    A brief overview is presented of the current materials and structures research geared toward propulsion applications for NASA s Subsonic Fixed Wing Project one of four projects within the Fundamental Aeronautics Program of the NASA Aeronautics Research Mission Directorate. The Subsonic Fixed Wing (SFW) Project has selected challenging goals which anticipate an increasing emphasis on aviation s impact upon the global issue of environmental responsibility. These goals are greatly reduced noise, reduced emissions and reduced fuel consumption and address 25 to 30 years of technology development. Successful implementation of these demanding goals will require development of new materials and structural approaches within gas turbine propulsion technology. The Materials and Structures discipline, within the SFW project, comprise cross-cutting technologies ranging from basic investigations to component validation in laboratory environments. Material advances are teamed with innovative designs in a multidisciplinary approach with the resulting technology advances directed to promote the goals of reduced noise and emissions along with improved performance.

    more complicated matter than meeting targets. While success may ultimately be justified in terms of a correspondence between aims and achievements, the understanding of both aspects is highly dependent on the project process. An example of a successful project that did not meet the original performance...... targets will serve to show that success is at matter of perspective as much as it is a matter of achievement. Other types of research, e.g. social psychology, have addressed the issue of success more explicitly. I draw on such literature to conceptualize project success anew and to reestablish...

    The experiences of the Juxian County Family Planning Committee of Shandong Province, China, were discussed in terms of the integration of family planning with income generation activities in rural areas. The integrated program was initiated in 1988 with pilot programs established by the Qiaoshan Family Planning Association to develop marketable skills in carpet weaving and grass braiding in Xiazhuang Town and Qiaoshan Township. The program gave priority of admission to women with only children and those who practiced family planning. 1400 women were recruited in these factories. Other income generation programs were developed for silkworm breeding and silk reeling, woolen embroidery, and printing. High ranking officials of the China Family Planning Association commended the work in income generation and family planning in Juxian County. This recognition spurred the second phase of development by the county family planning association: the establishment of village operated factories and mills for native products. By the end of 1991, there were 26 such projects in the county and per capita income to women increased by RMB 678 yuan. In the third stage of 1992, the number of association enterprises increased to 196 with recruitment of over 18,000 reproductive age women. The programs were initiated with collective funds from farmers and villages. The 170 projects in 1992 were developed with an investment of 9.6 million yuan, of which 2.26 million yuan was from individuals (23.5%). Emphasis was placed on self-reliance and recruitment of women with one child, women with 2 daughters and tubal ligations, and family planning motivators. The consequences of the integrated program were weakening traditional customs of marriage and childbearing, improvement in socioeconomic status of women, and effective service delivery of family planning and maternal and child health care services.

    Construction of infrastructure project is different from buildings. The main difference is term of project site where infrastructure project need to command a long stretch while building mostly confine to a limited area. As such factors that are critical to infrastructure project may not be that significant to building project and vice versa. Flood mitigation can be classified under infrastructure projects under which their developments are planned by the government with the specific objective to reduce or avoid the negative effects of flood to the environment and livelihood. One of the indicators in project success is delay. The impact of project delay in construction industry is significant that it decelerates the projects implementation, specifically the government projects. This study attempted to identify and compare the success factors between infrastructure and building projects, as such comparison rarely found in the current literature. A model of flood mitigation projects' success factors was developed by merging the experts' views and reports from the existing literature. The experts' views were obtained from the responses to open-ended questions on the required fundamentals to achieve successful completion of flood mitigation projects. An affinity analysis was applied to these responses to develop the model. The developed model was then compared to the established success factors found in building project, extracted from the previous studies to identify the similarities and differences between the two models. This study would assist the government and construction players to become more effective in constructing successful flood mitigation projects for the future practice in a flood-prone country like Malaysia.

  16. Project Management Yinyang: Coupling project success and client satisfaction

    Directory of Open Access Journals (Sweden)

    Greg Stewart Usher

    2017-06-01

    Full Text Available Our research applies paradox theory to a project management construct to help project management researchers and practitioners understand the tensions that can exist between project success and client satisfaction. Our research highlights that although project success and client satisfaction are both present within a project management construct, they also belong to different functional systems. Project success and client satisfaction have different systemic-discourses and use different language games to convey information. These distinctions can create latent and sometimes salient tensions within the project management construct that project managers must understand, embrace, and work with. We have used a Grounded Theory (GT methodology to explore the lived experience of project managers, and from this have identified a phenomenon which we have termed project management yinyang. Project management yinyang is the state that exists when both project success and Client satisfaction are tightly coupled within the project management construct. Project management yinyang highlights that these two phenomena cannot be viewed as separate elements because the ‘seed’ of each exists within the other. And to truly achieve one, you must also achieve the other. Our findings indicate that in order to create project management yinyang the project manager must embrace a paradoxical yet holistic philosophy. They must understand the complementarity, interdependency, and structural coupling that exists between the positivist and interpretivist paradigms within the project management construct. They must understand how satisfaction (Yin and success (Yang are created through focus. Furthermore, they must understand how project management yinyang is separate from, but borne from, the convergence of the other two elements.

    This study presents exploratory work and seeks to identify and evaluate the success and failure factors that could form a guideline for further study and to some extent help professionals to understand some critical aspects that impact project performance concerning construction in India. A total of 55 attributes affecting the performance of construction projects are analysed in terms of their level of influence on four key performance criteria – schedule, cost, quality, and no disputes – using a two-stage questionnaire survey. These attributes are then further analysed, interpreted and evaluated.   Based on the critical success factors obtained from the study, a neural network model-based predictive model for project performance has been developed. The performance prediction models have been derived for all four project performance criteria. Further, a hypothesis that ‘project success’ is influenced by ‘success traits’ has also been formulated. The hypothesized positive inter-relationships betwe...

    Full Text Available Aim/purpose - The study aims to investigate the relationship among the leadership, operational efficiency and project success in general and the impact of transformational leadership and operational efficiency on project success in particular. Design/methodology/approach - Mean comparison from descriptive statistics and multiple linear regression from inferential statistics was used to determine the association between variables and further impact of the transformational leadership and operational efficiency on project success in the development sector. The paper presents the results of a survey conducted among 200 employees from the top, middle & lower management levels of various national & international development organizations working in Pakistan like Microfinance Banks and other Rural Support Programs. Statistical Package for Social Sciences (SPSS was used to process data. Findings - The result shows positive association among transformational leadership, operational efficiency and project success. In addition, it was found that transformational leadership and operational efficiency have a positive and statistically significant impact on the project success. It is concluded that both transformational leadership and operational efficiency are vital to achieving the optimum level of success in any project, especially in the development sector. Research implications/limitations - The integral limitation of the study was the respondents because most of the development organizations have their operations in rural areas where access was difficult because of limited time and resources. In addition, such organizations are always reluctant to provide survey feedback. Originality/value/contribution - The paper contribution is in the theoretical and practical knowledge of the project success factors in the development sector which is still a somehow unexplored area. Regulators of the development sector may be benefited from this study.

  20. Structuring lighting retrofit projects for success

    International Nuclear Information System (INIS)

    Fetters, J.L.

    1993-01-01

    Several trends are converging to create a substantial market for lighting retrofits in these uncertain economic times. Low interest rates are making investments in buildings more attractive than alternative financial investments such as CD's. With activity in the new construction market at an all time low, savvy contractors are turning to the retrofit market - restoring, renovating and upgrading existing buildings. Heightened environmental concerns are fueling lighting incentive programs from the electric utilities and the EPA. Improvements in lighting technology are arriving in the marketplace at an accelerated rate. Building occupants are demanding higher quality workplaces and managers are seeking higher levels of productivity. Replacing older lighting equipment can substantially improve lighting efficiency, decrease energy and maintenance costs and, at the same time, improve the workplace by increasing lighting quality Lighting retrofit projects have a demonstrated track record, reducing lighting costs on the order of 50%. This experience can be applied to help structure retrofit projects. But, in order to reap all the benefits available from a retrofit project, it must be structured for success. The retrofit option introduces a unique series of issues for building owners, managers and engineers. The best way to prevent these issues from undermining the success of retrofit projects is to anticipate and completely plan for them. Successful retrofit projects run smoothER and stay within budgetary constraints. Three important considerations will guide the successful project: (1) Start comprehensive planning early, (2) Investigate existing conditions, and (3) Be sensitive to owner/occupants needs keep building operational

  3. Leadership success within disaster restoration projects.

    Science.gov (United States)

    Rapp, Randy R; Baroudi, Bassam

    2014-01-01

    Successful project managers draw their performance from essential leadership traits, as guided by their core values.Within disaster recovery, contractors who mitigate, repair, and reconstruct the built environment are often faced with challenges exceeding the norm. The effective leader is commonly expected to consider stakeholder motivations within distressing situations as well as other external and environmental factors when seeking to lead the project team to successful outcomes. This research is most concerned with leadership within the context of disaster restoration of the built environment. Its stimulus comes from the Restoration Industry Association (RIA)'s efforts to highlight leadership traits and core values for its Certified Restorer Body of Knowledge but would be of value to others associated with disaster recovery operations. Among organizations whose membership includes thousands of practitioners who restore and reconstruct the built environment after disasters, the RIA is the only one yet to formally and substantially research which core values and leader traits are deemed critical for the success of efforts to manage the means and methods applied on recovery job sites. Forty-six seasoned disaster restoration industry project professionals voluntarily responded to a survey questionnaire that sought their opinions about the traits and core values that they consider most important for successful disaster restoration project leadership. The most important leader traits were effective communication, professional competence, and leadership by example. The most important restoration industry values were integrity, compassion, and trustworthiness. The recognized imperative of compassion was unexpected in light of stereotypes often associated with construction-related contractors. This and other findings permit disaster response and recovery stakeholders to better understand qualities they should wish to see in leaders of contractor organizations, which

  4. Successful Control of Major Project Budgets

    2016-07-01

    Full Text Available This paper differs from scientific papers describing current research. In line with the theme of this special issue, it challenges conventional risk management practice against the background of former research results successfully finished decades ago. It is well-known that conventional practice frequently results in budget overruns of large projects. International reviews document that. Severe delays of schedules are also well-known. This paper describes successful research results from almost three decades ago, which successfully challenges this severe problem and has led to new practices. The research involved is an unusual mix: Scandinavian researchers from psychology, statistical theory and engineering economy. The resulting procedure has been widely used since around 1990 and challenges conventional procedures. The procedure is documented to be able to yield statistically correct prognoses, when the “rules of the game” have been correctly followed. After a short summary of the basic situation, this paper summarizes the research, followed by some resulting experiences, focusing on two recent studies each of 40 infrastructures and other major projects. In both sets, the actual final cost largely equaled the expected project cost. This result is a marked change from international past and present experience. Finally, the need for further research and progress is discussed.

  6. Examination of the relationship between project management critical success factors and project success of oil and gas drilling projects

    Science.gov (United States)

    Alagba, Tonye J.

    Oil and gas drilling projects are the primary means by which oil companies recover large volumes of commercially available hydrocarbons from deep reservoirs. These types of projects are complex in nature, involving management of multiple stakeholder interfaces, multidisciplinary personnel, complex contractor relationships, and turbulent environmental and market conditions, necessitating the application of proven project management best practices and critical success factors (CSFs) to achieve success. Although there is some practitioner oriented literature on project management CSFs for drilling projects, none of these is based on empirical evidence, from research. In addition, the literature has reported alarming rates of oil and gas drilling project failure, which is attributable not to technical factors, but to failure of project management. The aim of this quantitative correlational study therefore, was to discover an empirically verified list of project management CSFs, which consistent application leads to successful implementation of oil and gas drilling projects. The study collected survey data online, from a random sample of 127 oil and gas drilling personnel who were members of LinkedIn's online community "Drilling Supervisors, Managers, and Engineers". The results of the study indicated that 10 project management factors are individually related to project success of oil and gas drilling projects. These 10 CSFs are namely; Project mission, Top management support, Project schedule/plan, Client consultation, Personnel, Technical tasks, Client acceptance, Monitoring and feedback, Communication, and Troubleshooting. In addition, the study found that the relationships between the 10 CSFs and drilling project success is unaffected by participant and project demographics---role of project personnel, and project location. The significance of these findings are both practical, and theoretical. Practically, application of an empirically verified CSFs list to oil

  10. Quantum theory of successive projective measurements

    International Nuclear Information System (INIS)

    Johansen, Lars M.

    2007-01-01

    We show that a quantum state may be represented as the sum of a joint probability and a complex quantum modification term. The joint probability and the modification term can both be observed in successive projective measurements. The complex modification term is a measure of measurement disturbance. A selective phase rotation is needed to obtain the imaginary part. This leads to a complex quasiprobability: The Kirkwood distribution. We show that the Kirkwood distribution contains full information about the state if the two observables are maximal and complementary. The Kirkwood distribution gives another picture of state reduction. In a nonselective measurement, the modification term vanishes. A selective measurement leads to a quantum state as a non-negative conditional probability. We demonstrate the special significance of the Schwinger basis

    Full Text Available The success of international construction projects is fraught with various challenges such as competitiveness, lack of resources, versatile global economy, and specific conditions in the host country. Malaysian contractors have been venturing into global construction market since early 1980s. However, their venturing was not successful all the time. The number of international projects awarded to Malaysian contractors has reduced drastically during the past decade. Taking advantage of this experience, this paper aims to identify the success criteria and success factors of international construction projects. The data was collected from 120 respondents using a questionnaire survey and analysed using principal component analysis and regression analysis. The results revealed three principal criteria of project success namely, Management Success, Functional Success, and Organisation Success. The main components of success factors include Team Power and Skills, Resource Availability, External Environment, Organisation Capability, Project Support, and Project Organisation. Further analysis emphasized the importance of strong financing capacity of contractors, project social environment, and competence of the project manager in achieving project success. The results of this paper can serve as a guideline for contractors and project managers to achieve success in this context. Future studies may provide in-depth analysis of success criteria and success factors specific for construction project type and host-country location.

    Full Text Available The relationship between psychological empowerment of stakeholders and project success is an important thing that must be known by project manager. This research developed and tested the model to predict how well the impact of stakeholder psychological empowerment on project success. Stakeholder psychological empowerment was defined to have five indicator variables covering intrinsic motivation, opportunity to perform, ability to perform, task behaviors, and contextual behaviors. Meanwhile, project success can be measured by cost performance, time performance, quality performance, profitability, and customer satisfaction. In this study, it was hypothesized that stakeholder psychological empowerment influenced project success. Based on the data obtained from a questionnaire survey carried out to 204 respondents, structural equation modeling (SEM was used for predicting the performance of project success. It was found that stakeholder psychological empowerment influenced project success, especially on the ability to perform of stakeholders.

    Full Text Available Successful management of an information technology (IT project is the most desirable for all organisations and stakeholders. Many researchers elaborated that risk management is a key part of project management for any project size. Risk management is so critical because it provides project managers with a forward-looking view of both threats and opportunities to improve the project success. The objectives of this research are to explore organisational factors affecting IT project success and risk management practices influencing IT project success. Risk management practices include risk identification, risk analysis, risk response planning, and risk monitoring and control. The IT project success is measured by process performance and product performance. Data are collected from 200 project managers, IT managers, and IT analysts in IT firms through questionnaires and analysed using Independent Sample t-test, One-way ANOVA, and Multiple Linear Regression at the statistical significance level of 0.05. The results show that the differences in organisational types affect IT project success in all aspects, while the differences on organisational sizes affect IT project success in the aspect of product performance and total aspects. Risk identification and risk response planning influence the process performance and the total aspects of IT project success. Risk identification has the highest positive influence on product performance, followed closely by risk response, while risk analysis negatively influences product performance.

    In May 1998, the US Environmental Agency (EPA) certified the US Department of Energy's (DOE) Waste Isolation Pilot Plant (WIPP) as being in compliance with all of the applicable regulations governing the permanent disposal of spent nuclear fuel, high-level waste, and transuranic radioactive waste. The WIPP, a transuranic waste repository, is the first deep geologic repository in the US to have successfully demonstrated regulatory compliance with long-term radioactive waste disposal regulations and be certified to receive wastes. Many lessons were learned throughout the 25-year history of the WIPP--from site selection to the ultimate successful certification. The experiences and lessons learned from the WIPP may be of general interest to other repository programs in the world. The lessons learned include all facets of a repository program: programmatic, managerial, regulatory, technical, and social. This paper addresses critical issues that arose during the 25 years of WIPP history and how they influenced the program

    Last October, the ARPS initiated a new observing project to make photometric observations of asteroids which reach a phase angle of 0.2° or less at opposition. The stimulus for this followed the naming last year of asteroid (7102) in honour of Neil Bone, our former Meteor Section Director, who sadly died last year. It turned out that (7102) would reach opposition on January 18 this year at an unusually low phase angle - just 0.03°. This is so small an angle that if you were standing on the asteroid on this date, you would be able to see the Earth transiting across the face of the Sun! The probability that (7102) would attain such a low phase angle is about once in several hundred years. So our project was set up with a view to observing its namesake along with a selection of thirteen other asteroids, which also happened to pass through very low phase angle at their opposition during the period 2009 October-2010 March.

    Full Text Available The purpose of this paper is to rank construction projects' success in a post delivery phase. To attain this objective, a data envelopment analysis (DEA approach is used. The model's output is a project success index which is calculated based on five project success criteria. These criteria which are determined by a two-round Delphi questionnaire survey are time performance, cost performance, quality, HSE, and customer satisfaction. The input factors which have effects on the output measures are Organizational Sponsorship, Project Manager Competency, Customer Organization, Project Operational Environment and Organizational Experience. The tool adopted to determine these factors is questionnaire. This model is applied for 9 projects with different importance of output and input factors and the reasonable result is achieved for ranking these projects.

    Existing research on antecedent of funding success mainly focuses on basic project properties such as funding goal, duration, and project category. In this study, we view the process by which project owners raise funds from backers as a persuasion process through project descriptions. Guided by the unimodel theory of persuasion, this study identifies three exemplary antecedents (length, readability, and tone) from the content of project descriptions and two antecedents (past experience and past expertise) from the trustworthy cue of project descriptions. We then investigate their impacts on funding success. Using data collected from Kickstarter, a popular crowdfunding platform, we find that these antecedents are significantly associated with funding success. Empirical results show that the proposed model that incorporated these antecedents can achieve an accuracy of 73 % (70 % in F-measure). The result represents an improvement of roughly 14 percentage points over the baseline model based on informed guessing and 4 percentage points improvement over the mainstream model based on basic project properties (or 44 % improvement of mainstream's performance over informed guessing). The proposed model also has superior true positive and true negative rates. We also investigate the timeliness of project data and find that old project data is gradually becoming less relevant and losing predictive power to newly created projects. Overall, this study provides evidence that antecedents identified from project descriptions have incremental predictive power and can help project owners evaluate and improve the likelihood of funding success.

  9. Successful healthcare programs and projects: organization portfolio management essentials.

    2005-01-01

    Many healthcare organization projects take more time and resources than planned and fail to deliver desired business outcomes. Healthcare IT is a major component of many projects and often undeservedly receives the blame for failure. Poor results are often not a result of faulty healthcare IT or poor project management or poor project execution alone. Many projects fail because of poor portfolio management--poor planning and management of the portfolio of initiatives designed to meet an organization's strategic goals. Because resources are limited, portfolio management enables organizations to more strategically allocate and manage their resources so care delivery, service delivery, and initiatives that advance organizations toward their strategic goals, including healthcare IT initiatives, can be accomplished at the levels of quality and service desired by an organization. Proper portfolio management is the essential foundation for program and project success and supports overall organization success. Without portfolio management, even programs and projects that execute flawlessly may not meet desired objectives. This article discusses the essential requirements for porfolio management. These include opportunity identification, return on investment (ROI) forecast, project prioritization, capacity planning (inclusive of human, financial, capital, and facilities resources), work scheduling, program and project management and execution, and project performance and value assessment. Portfolio management is essential to successful healthcare project execution. Theories are drawn from the Organizational Project Management Maturity Model (OPM3) work of the Project Management Institute and other leading strategy, planning, and organization change management research institutes.

  11. Understanding Megaproject Success beyond the Project Close-Out Stage

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Project success has always been an important topic in the project management literature. One of the main discussions is concerned with how a project’s success is evaluated and what factors lead to achieving this success. Traditionally project success has been measured at the point where the project outputs are handed over, after the close out phase. Recently, questions have been raised in the literature as to whether we should be evaluating project success beyond the close out phase, to better account for organizational and societal outcomes.  However, not much has been published about how the long term impacts and outcomes are measured. This is of particular concern in megaprojects as they often attract a high level of public attention and political interest, and have both direct and indirect impacts on the community, environment, and national budgets. In this paper the authors review success factors and criteria that are applicable to projects in general and megaprojects in particular. They identify the significance of evaluating outcomes and impact and propose an ex-post project evaluation (EPPE framework for megaprojects.

    Purpose The purpose of this paper is to present findings from a study of factors that affect continuous improvement (CI) project success in hospitals. Design/methodology/approach Quantitative regression analysis was performed on Likert scale survey responses. Qualitative thematic analysis was performed on open-ended survey responses and written reports on CI projects. Findings The paper identifies managerial and employee factors that affect project success. These factors include managerial support, communication, and affective commitment. Affective commitment is the extent to which employees perceive the change as being needed or necessary. Practical implications The results highlight how managerial decisions, approaches to communication - including communication before, during and after CI projects affect project success. The results also show that success depends on the way employees perceive proposed changes. This suggests the need for a more individualized approach to CI, lean, and broader change initiatives. Originality/value This research is the first to fuse project success and sustainability theory to CI projects, beyond Kaizen events, in healthcare environments. The research is particularly important at a time when healthcare organizations are required to make rapid changes with limited resources as they work toward outcome-based assessment and reimbursement rules.

    Full Text Available Absorption of European funds is on top of Romania’s public agenda for the last years although the first programming period has ended and the necessary lessons were learned so far. To have a high degree of absorption of funds provided by the EU must be of quality projects and their implementation to be successful. Through this work we aimed to investigate the success factors of infrastructure projects with European funding in Romania, Bulgaria, Moldova, Ukraine, Serbia and Kosovo, and identify critical success factors of these projects through a research surveying the teams of consultants and support personnel from the countries in an international consulting company. The research results are therefore constitute the empirical evidence of what constitutes critical success factors of infrastructure projects financed by the European Union and can be used as a starting point for scientific studies of the management of European projects or other actions that investigates measures that can be taken to improve the success rate of projects implemented in the area mentioned above.One of the contributions of this paper is to identify the critical success factors of success factors present in literature. With more so as they are critical success factors of infrastructure projects with European funding still required field studies and analysis performed in the present context. In addition, the critical factors were operationalized in a conceptual framework. Moreover, this framework includes leadership style of project manager as critical success factor has been identified in the research as the most important in the context in which it was conducted. As such, this paper demonstrates, with the necessary limitations, the importance of management style of project managers in the context of specific European funded infrastructure projects. And this is happening even though there are sophisticated project management tools availabe and relevant knowledge exists

  18. Critical Success Factors for Malaysian Construction Projects: An Investigative Review

    Full Text Available Construction projects play an important role in the advancement of a nation through infrastructure development that leads to economic growth. They are planned carefully to accomplish certain goals. However, not all the projects achieved the goals as per planned. Many factors contribute to the successes and failures, and it becomes an interesting arena for research. The primary objective of this paper is to outline the development trend of project success measurement globally and locally. The research method employed was to make selected reviews on critical success factors' (CSFs literature and to compare international standards and progress in incorporating human behavioural aspects of project management to the situation in Malaysia. A somewhat similar pattern can be observed in Malaysia where the studies have departed from the usual criteria of time, cost and quality, to define project success in a more holistic way. However, the domestic industry has failed to respond to the emerging trend globally as there has yet been any widely published research on the importance of human-related factors towards project success. A consolidated framework of CSFs has therefore, been proposed in responding to the findings. This paper fulfils an identified need as there has been a dearth of research on the subject matter locally.

    2012-05-01

    Full Text Available This study evaluates the concept of success in project management that is applicable to the IT universe, from the classical theory associated with the techniques of project management. Therefore, it applies the theoretical analysis associated to the context of information technology in enterprises as well as the classic literature of traditional project management, focusing on its application in business information technology. From the literature developed in the first part of the study, four propositions were prepared for study which formed the basis for the development of the field research with three large companies that develop projects of Information Technology. The methodology used in the study predicted the development of the multiple case study. Empirical evidence suggests that the concept of success found in the classical literature in project management adjusts to the environment management of IT projects. Showed that it is possible to create the model of standard IT projects in order to replicate it in future derivatives projects, which depends on the learning acquired at the end of a long and continuous process and sponsorship of senior management, which ultimately results in its merger into the company culture.

    Full Text Available The International Successful School Principalship Project (ISSPP has been actively conducting research about the work of successful principals since 2001. Findings from four project books and eight models derived from this project are synthesised into a model of successful school leadership. Building on Gurr, Drysdale and Mulford’s earlier model, the work of school leaders is described as engaging within the school context to influence student and school outcomes through interventions in teaching and learning, school capacity building, and the wider context. The qualities a leader brings to their role, a portfolio approach to using leadership ideas, constructing networks, collaborations and partnerships, and utilising accountability and evaluation for evidence-informed improvement, are important additional elements. The model is applicable to all in leadership roles in schools.

  4. Servant leadership behaviors of aerospace and defense project managers and their relation to project success

    Science.gov (United States)

    Dominik, Michael T.

    The success of a project is dependent in part on the skills, knowledge, and behavior of its leader, the project manager. Despite advances in project manager certifications and professional development, the aerospace and defense industry has continued to see highly visible and expensive project failures partially attributable to failures in leadership. Servant leadership is an emerging leadership theory whose practitioners embrace empowerment, authenticity, humility, accountability, forgiveness, courage, standing back, and stewardship, but has not yet been fully examined in the context of the project manager as leader. The objective of this study was to examine the relationship between servant leadership behaviors demonstrated by aerospace and defense project managers and the resulting success of their projects. Study participants were drawn from aerospace and defense oriented affinity groups from the LinkedInRTM social media web system. The participants rated their project managers using a 30-item servant leadership scale, and rated the success of their project using a 12-item project success scale. One hundred and fifteen valid responses were analyzed from 231 collected samples from persons who had worked for a project manager on an aerospace and defense project within the past year. The results of the study demonstrated statistically significant levels of positive correlation to project success for all eight servant leadership factors independently evaluated. Using multiple linear regression methods, the servant leadership factors of empowerment and authenticity were determined to be substantial and statistically significant predictors of project success. The study results established the potential application of servant leadership as a valid approach for improving outcomes of projects.

    2015-07-01

    Full Text Available Since there is a lack of studies about the relationship of IT project manager competencies and project success, this paper will address the following research question: Which competencies should IT project managers develop in order to achieve success in IT projects? To answer this question, we conducted a qualitative research with an exploratory approach. To collect data, twelve (12 in-depth interviews were done with Brazilian project managers from different companies from several business sectors. The analysis results pointed out that for our respondents the most needed category of competencies are team management, business domain knowledge,  communication, project management and people skills. As other authors have affirmed, technical skills were considered to be less relevant to project success than interpersonal and intrapersonal competencies.

    2017-04-01

    According to demographers, psychologists, sociologists and economists diverse groups, which are groups of different race, ethnicity, gender and sexual orientation, are more innovative than homogeneous groups. This is also true for groups working together in research collaborations and international cooperation involving a culturally and functionally diverse mix of individuals who have to be integrated into an effective unit - a project team. If the goal is scientific excellence, diversity should be an essential ingredient to conduct science on high level productivity, quality and innovation. Effective teamwork is a key to project success and prime responsibilities of the project manager. Therefore, the project manager has to take into consideration different characteristics such as cultures, languages, and different values related to individual project partners. Here we show how diversity can affect the performance of a research project. Furthermore, the presentation indicates skills and abilities which are required for the management in order to deal also with the challenges of diversity in research projects. The presentation is based on insights experienced in the context of an Innovative Training Network (ITN) project within Marie Skłodowska-Curie Actions of the European HORIZON 2020 program and TRION a Collaborative Research Project in the Framework of the Trilateral Program of the German Research Foundation.

    This paper presented a historical summary of traditional project management along with a discussion on the project management and development philosophy that can be used in a large infrastructure company that develops and operates its own projects and facilities. Two case studies from the experiences of TransCanada Pipelines Limited were also presented. It was suggested that companies seeking a first-rate reputation must maintain a long-term focus with emphasis on the improvement of the total process and harmony with the environment and community. This paper explained how project managers can create balance between the proponents, stakeholders, participants and the people and the environment while ensuring a cost effective quality product over time. Successful project managers were shown to understand and manage the components of scope, time, cost, quality, human resources, communication, risk, purchasing, safety and harmony with the community. Project development from the perspective of an owner-operator was presented with reference to consistency in approach and the decision making process. It was concluded that although project managers should focus on controlling and minimizing capital expenditures during project engineering and construction, the many elements that contribute to a project's value should also be recognized. 10 refs., 6 figs.

  11. Successful integration of fast track projects into turnarounds

    Williams, J. Patrick; Loureiro, Ramon C. [KBC Advanced Technologies, Surrey (United Kingdom)

    2012-07-01

    Fast track projects can provide quick wins and competitive advantage. However, in most cases the implementation of these projects requires a shutdown for installing the necessary tie-ins or integration into an upcoming turnaround (TA). Depending on the nature of the project and complexity of the TA, the integration can be seamless or result in cost or duration overruns and safety incidents. The risk of such overruns and safety incidents increases with the amount of project work to be integrated into the operations, maintenance and inspection schedules to be executed during the TA. The risk further increases with TA size and other factors. If not planned and scheduled properly and in a timely fashion, capital projects, in particular fast track projects trying to take advantage of an upcoming TA, can severely impact both TA performance, and the safety and reliability of the facility until the next opportunity for eliminating the defects introduced during the TA. Successful TAs are those delivered in a safe, on time, on budget manner, and with the quality standards needed for a leak-free start-up and a safe and reliable operation over the next run cycle. This paper discusses the key elements that are required to minimize the TA risks derived from the inclusion of fast track projects and how to establish the cut off criteria to either cancel or defer the project, or delay the TA in order to balance TA scope freeze and the case for compelling economics.(author)

    The rapid economic development has increased the demand for construction of infrastructure and facilities globally. Sustainable development and globalization are the new ‘Zeitgeist’ of the 21st century. In order to implement these projects successfully and to meet the functional aim of the projects within their lifetime, an efficient project management practice is needed. The aim of this study is to identify the critical success factors (CSFs) and the extent of use of project management practice which affects project success, especially during the implementation stage. Data were obtained from self-administered questionnaires with 232 respondents. A mixed method of data collection was adopted using semi-structured interview and questionnaire approach. The result of the analysis of data obtained showed that new and emerging criteria such as customer satisfaction, competency of the project team, and performance of subcontractors/suppliers are becoming measures of success in addition to the classic iron triangle’s view of time, cost and quality. An insight on the extent of use of different project management practice in the industry was also achieved from the study.

Effective Project Management overcomes these types of challenges. This study identifies the success factors which are important for project management in construction project success. From the literature review, 26 factors were found to be critical. Project managers, construction managers, civil engineers, contractors and site engineers were the respondents. After analyzing the data in SPSS software, the dominant factors from the regression analysis are top management support, competent project team, abilities to solve problems, realistic cost and time estimates, information/communication, competency of the project manager are the 6 factors out of 12 in 26 factors. Effective communication between stakeholders got highest priority and client involvement, good leadership, clarity of project goals got second priority. Informal communication gives better results compared to formal communications like written formats. To remove communication barrier with the stakeholders, informal communication like speaking face-to-face with the language this fits for the stakeholders.

    Unlike user created password, number of biometrics is limited for creating account in different organizations. Transformed biometrics attempts to solve the problem by transforming the biometric into another form, which is unique to the particular organization. This makes the availability of different transformed biometrics in different organizations transformed from the same biometrics and helps in foolproof transactions. In this article a novel approach to transformed biometrics using successive projection technique is suggested .In the proposed technique, the user can register up to 5*4n-1 organizations if the length of the biometric password is 'n'.

    Award of the degree MD has special relevance in Germany since the underlying research project can be started during the qualification for admission to doctoral training. This leads to a large number of thesis projects with a not always sufficiently pronounced enthusiasm and thus poor chances of success. Accordingly a case control study was undertaken in the Department of Human Medicine, Witten/Herdecke University to investigate reported drop-outs of thesis projects. In autumn 2012 all students in the clinical phases of human medicine education were surveyed using a self-conceived questionnaire on previously initiated or terminated thesis projects, "terminated" is defined as the unsuccessful ending of a project after working for at least 3 months. Individually reported thesis terminations were evaluated using defined items in a 4-stage Likert scale regarding thesis plan and project, subsequently, graduate students who successfully completed a project received the same questionnaire. The items possibly corresponding to process determinants were averaged to a total of 7 dimensions prior to the analysis; the resulting scores were normalised in value ranges 0.0 to 1.0 (1.0 = optimal project situation) whereby individual items could be included in several scores. By means of 5 items a primary endpoint from the faculty's perspective on "compliance with formal procedures" was aggregated; by means of a two-sided Wilcoxon test at the 5 % level students with unsuccessful and successful courses were compared along the corresponding scores. 181 of 276 students from 7 study semesters participated in the screening; details of 17 terminations and 23 currently successful courses could be evaluated in the case control study. For significant differences (p thesis projects to the responsible committees. A weakness is the low number of evaluable self-reported drop-outs as well as the overall moderate response rate.

  20. Impact of Leadership Styles on Project Success – The Case of a Multinational Company

    Directory of Open Access Journals (Sweden)

    Bálint Blaskovics

    2014-11-01

    Full Text Available Literature on project success mainly focused on identifying and analyzing success criteria and critical success factors. Success criteria are used for evaluating the success of a project and critical success factors are those factors which increase the potential for achieving project success. However, the interrelationships among them were rarely analyzed, although researchers highlighted the importance of these interrelationships. The aim of the paper is to identify a leadership style, of which project managers can maximize the potential for achieving project success. Project success is analyzed from the point of view of success criteria. This approach manages the shortcoming mentioned above, the lack of analyzing interrelationships among critical success factors and success criteria. This outcome is drawn from qualitative field research at a subsidiary of a Scandinavian-based multinational company.

    2014-05-01

    Since the 1990s, French operational managers and scientists have been involved in the environmental restoration of rivers. The European Water Framework Directive (2000) highlights the need for feedback from restoration projects and for evidence-based evaluation of success. Based on 44 French pilot projects that included such an evaluation, the present study includes: 1) an introduction to restoration projects based on their general characteristics 2) a description of evaluation strategies and authorities in charge of their implementation, and 3) a focus on the evaluation of results and the links between these results and evaluation strategies. The results show that: 1) the quality of an evaluation strategy often remains too poor to understand well the link between a restoration project and ecological changes; 2) in many cases, the conclusions drawn are contradictory, making it difficult to determine the success or failure of a restoration project; and 3) the projects with the poorest evaluation strategies generally have the most positive conclusions about the effects of restoration. Recommendations are that evaluation strategies should be designed early in the project planning process and be based on clearly-defined objectives. Copyright © 2014 Elsevier Ltd.

    The energy change is the most important common work of the German after-war history. And it offers a unique collective field of learning, how the socio-ecological transformation can be converted in practice. If the energy change succeeds in an industrial country like Germany, many other countries can follow this example. The Bund fuer Umwelt und Naturschutz Deutschland (BUND) and the Vereinigung Deutscher Wissenschaftler (VDW) show as editors, what now must be done in order that the energy change becomes a success. Because currently threatens the energy change to be slowed down by the policy and talked to death by many stakeholders in the industry. This book demonstrates why the energy change is necessary and how it can succeed. It shows what has to be done and wants to use the existing enthusiasm in order to lead the common project energy change jointly to success. What is needed is a long-term policy that finally takes the reduction of energy consumption in attack.

    For the past two years, Cal Poly's rocket program has been aggressively exploring the concept of remotely controlled, fixed wing, flyable rocket boosters. This program, embodied by a group of student engineers known as Cal Poly Space Systems, has successfully demonstrated the idea of a rocket design that incorporates a vertical launch pattern followed by a horizontal return flight and landing. Though the design is meant for supersonic flight, CPSS demonstrators are deployed at a subsonic speed. Many steps have been taken by the club that allowed the evolution of the StarBooster prototype to reach its current size: a ten-foot tall, one-foot diameter, composite material rocket. Progress is currently being made that involves multiple boosters along with a second stage, third rocket.

    2015-11-01

    Full Text Available In the built environment (BE sector, the co-creation process of design demands understanding of requirements (as viewed by parties involved, mobilisation of tacit knowledge, negotiation, and complex exchange of information. The need to collaborate over distance has further exacerbated the complexity of the process, and, in itself, represents a significant challenge for BE professionals who are increasingly expected to undertake this process within globally distributed virtual teams. The research aims to identify key success factors and develop guidance for international collaborative design projects, via the implementation of collaborative design courses in UK and Canadian universities over three academic years. Questionnaire surveys, focus groups, observation of online meetings, personal reflections provided data for the analysis. The findings reveal the significance of the perceived risk of collaboration and a difference in preferred communication mode between architects and civil/structural engineers. These findings suggest the impact of training in the subject discipline, and that the opportunity for co-located working has helped the development of trust. The guidance is aimed at BE educators who wish to implement this activity in their courses.

    2007-01-01

    Projects are the engines that drive innovation from idea to commercialization. In fact, the number of projects in most organizations today is expanding while operations is shrinking. Yet, since many companies still focus on operational excellence and efficiency, most projects fail--largely because conventional project management concepts cannot adapt to a dynamic business environment. Moreover, top managers neglect their company's project activity, and line managers treat all their projects alike--as part of operations. Based on an unprecedented study of more than 600 projects in a variety of businesses and organizations around the globe, "Reinventing Project Management" provides a new and highly adaptive model for planning and managing projects to achieve superior business results.

  12. Application fuzzy multi-attribute decision analysis method to prioritize project success criteria

    Phong, Nguyen Thanh; Quyen, Nguyen Le Hoang Thuy To

    2017-11-01

    Project success is a foundation for project owner to manage and control not only for the current project but also for future potential projects in construction companies. However, identifying the key success criteria for evaluating a particular project in real practice is a challenging task. Normally, it depends on a lot of factors, such as the expectation of the project owner and stakeholders, triple constraints of the project (cost, time, quality), and company's mission, vision, and objectives. Traditional decision-making methods for measuring the project success are usually based on subjective opinions of panel experts, resulting in irrational and inappropriate decisions. Therefore, this paper introduces a multi-attribute decision analysis method (MADAM) for weighting project success criteria by using fuzzy Analytical Hierarchy Process approach. It is found that this method is useful when dealing with imprecise and uncertain human judgments in evaluating project success criteria. Moreover, this research also suggests that although cost, time, and quality are three project success criteria projects, the satisfaction of project owner and acceptance of project stakeholders with the completed project criteria is the most important criteria for project success evaluation in Vietnam.

    1992-12-01

    Redwing is the largest completed Cleanroom software engineering project in IBM, both in terms of lines of code and project staffing. The product provides a decision-support facility that utilizes artificial intelligence (AI) technology for predicting and preventing complex operating problems in an MVS environment. The project used the Cleanroom process for development and realized a defect rate of 2.6 errors/KLOC, measured from first execution. This represents the total amount of errors that were found in testing and installation at three field test sites. Development productivity was 486 LOC/PM, which included all development labor expended in design specification through completion of incremental testing. In short, the Redwing team produced a complex systems software product with an extraordinarily low error rate, while maintaining high productivity. All of this was accomplished by a project team using Cleanroom for the first time. An 'introductory implementation' of Cleanroom was defined and used on Redwing. This paper describes the quality and productivity results, the Redwing project, and how Cleanroom was implemented.

Ltd, Haiyang, Shandong 265118 (China)

    2010-06-15

    Chinese electric power industry has adopted Build-Operate-Transfer (BOT) approach in a number of projects to alleviate the pressure of sole state-owned investment. The Chinese government has taken enormous efforts to create an environment to facilitate the application of BOT approach in electric power projects. Moreover, the growing attention on the sustainability issues puts the traditional major source of electricity - thermal power project under more strict scrutiny. As a result, various renewable energy projects, particularly the wind power projects have involved private sector funds. Both thermal power and wind power projects via BOT approach have met with a varying degree of success. Therefore, it is imperative to understand the factors contributing towards the success of both types of BOT power projects. Using an extensive literature survey, this paper identifies 31 success factors under 5 categories for Chinese BOT electric power projects. This is followed by a questionnaire survey to exam relative significance of these factors. The results reveal the different levels of significance of success factors for BOT thermal power projects versus wind power projects. Finally, survey results were analyzed to explore the underlying construction and distributions among the identified success factors. This study provides a valuable reference for all involved parties that are interested in developing BOT electric power projects in China. (author)

    2013-01-01

    Full Text Available The success of IT projects is influenced by risk and risk management according to the existing project management literature. The paper emphasizes the role of risk management and its contribution to projects success in the existing literature. The methodology applied is based on documentary study review and analysis of the concepts used by the literature. We analyzed the literature published between 1978 and 2012 from the main IT project management journals and publications. The results are that risk management is a very important component of the project management process and it is assumed implicitly to work in favour of project success. We also performed a quantitative analysis of how risk management processes affect the subjective and objective performance of IT projects in Romanian IT companies.

    Every business suffers from excessive regulations, unpredictable changes in legislation, various kinds of the political rent, extorting practices like 'big business social responsibility' and more. The industries with long-term return-of-investment (ROI) are most vulnerable to political and legal risks. For the nuclear industry, long-lasted public perception of radiation as an imminent threat caused the present over-regulation look natural. Therefore ROI is above two decades, essentially precluding private entrepreneurship activity. While durable solution includes changing public perception and updating regulation, both are 'facts on the ground' and 'habits are hard to break'. Political alliances, appeal to public opinion and lobbying are legitimate methods for promoting industry's interests in a democratic state. However in case of the nuclear industry, bureaucratic and political interests seem too strong to be overpowered by regular lobbying activities. Durable solutions we are searching for should not only eliminate the present legal and political obstacles, but also prevent them in near- to middle-term future. Such solutions would mitigate risks and remove barriers in number of industries, including nuclear industry as well. Particularly, 'not in my backyard' (NIMBY) attitude to nuclear installations is often viewed as a formidable problem. However, this problem has pretty old and reliable solution via compensation for real estate devaluation, if such takes place. Such solution may preclude some projects, but makes others predictable and reliable (e.g. in sparsely populated or relatively poor areas)

    Conserving viable populations of plant species requires that they have high probabilities of long-term persistence within natural habitats, such as a chance of extinction in 100 years of less than 5% (Menges 1991, 1998; Brown 1994; Pavlik 1994; Chap. 1, this Vol.). For endangered and threatened species that have been severely reduces in range and whose habitats have been fragmented, important species conservation strategies may include augmenting existing populations or restoring new viable populations (Bowles and Whelan 1994; Chap. 2, this Vol.). Restoration objectives may include increasing population numbers to reduce extinction probability, deterministic manipulations to develop a staged cohort structure, or more complex restoration of a desired genetic structure to allow outcrossing or increase effective population size (DeMauro 1993, 1994; Bowles et al. 1993, 1998; Pavlik 1994; Knapp and Dyer 1998; Chap. 2, this Vol.). These efforts may require translocation of propagules from existing (in situ) populations, or from ex situ botanic gardens or seed storage facilities (Falk et al. 1996; Guerrant and Pavlik 1998; Chap. 2, this Vol.). Population viability analysis (PVA) can provide a critical foundation for plant restoration, as it models demographic projections used to evaluate the probability of population persistence and links plant life history with restoration strategies. It is unknown how well artificially created populations will meet demographic modeling requirements (e.g., due to artificial cohort transitions) and few, if any, PVAs have been applied to restorations. To guide application of PVA to restored populations and to illustrate potential difficulties, we examine effects of planting different life stages, model initial population sizes needed to achieve population viability, and compare demographic characteristics between natural and restored populations. We develop and compare plant population restoration viability analysis (PRVA) case studies of

    Project success is strongly linked to communication and cooperation between stakeholders. This research explores the relationship between trust and communication and tests the influence of these factors upon project success and success criteria for international development projects financed by multilateral institutions in sub-Saharan Africa. The research analyses the coordinators' perceptions of project success, communication climate and interpersonal relationship between himself and his stakeholders (task manager in the multilateral agency, national supervisor) and within the project team. Data were collected from questionnaires completed by project coordinators of development projects. The statistical analysis confirms that trust and communication between players are proxy variables. Trust between the task manager and the coordinator is the key success factor, whereas team cohesion is the second most important factor. Trust between the coordinator and his national supervisor does not play a prominent role, although the task manager considers significant local autonomy for the coordinator a prerequisite for funding a subsequent phase when the project comes to an end.

    Land-use planning poses a significant barrier to the further development of on-shore wind energy in many countries. There has been increasing discussion regarding the use of public participation in the planning process in order to address concerns of local residents and ease conflicts. This research explores the dynamics of the planning process for wind energy in England, Wales and Denmark in order to better understand the factors influencing project success. Through 18 in-depth case studies, it investigates the degree of local community participation in the planning process and the stability of the network of individuals and organisations involved in the project to determine their relationship to the public's acceptance of the project and the planning outcome. The study draws on the frameworks of public participation in planning and actor-network theories in order to develop indicators of the level of community involvement and network formation for each case. The analysis discusses predictions made by the theoretical approaches as to the importance of these variables to the success of new projects. The results indicate that projects with high levels of participatory planning are more likely to be publicly accepted and successful. In addition, stable supporting networks are more likely to form. The presence of a stable network of supporters is not found to be related to project acceptance and success; however, the absence of a stable network of opponents is found to be necessary for project acceptance and success in receiving planning permission

    The largest source of funding for alternative fuel vehicle and infrastructure projects in the U.S. Department of Energy's Clean Cities program's history came from the American Recovery and Reinvestment Act (Recovery Act). In 2009, the 25 cost-share projects totaled nearly $300 million in federal government investment. This effort included the involvement of 50 Clean Cities coalitions and their nearly 700 stakeholder partners who provided an additional $500 million in matching funds to support projects in their local communities. In total, those 25 projects established 1,380 alternative fueling stations and put more than 9,000 alternative fuel and advanced technology vehicles on the road. Together, these projects displaced 154 million gasoline gallon equivalents (GGE) of petroleum and averted 254,000 tons of greenhouse gas (GHG) emissions, while supporting U.S. energy independence and contributing to regional economic development. During post-project interviews, project leaders consistently cited a number of key components - ranging from technical and logistical factors, to administrative capabilities - for accomplishing an effective and impactful project. This report summarizes the high-level project design and administrative considerations for conducting a successful transportation project.

    Full Text Available The paper proposes a systematization of the key success factors of projects, through the theoretical review of family-owned companies operating in the EU market. It is the small and medium companies that in their own way contribute to the overall success of the national economy in terms of economic activity, increased employment, development activities and defining better business environment. The theoretical review observed numerous studies of family businesses, and the contribution of this work is in the systematization of the results of previous research – over three horizons, i.e., over the role of managers in the creation of successful projects (or owner if it is a family enterprise, institutional support for companies in Serbia and the EU, specific industries and the parent (regional markets where a family company operates. Project management, as a general representation of the concept of implementation of strategic and operational endeavors, contains many specifics in terms of critical success factors of projects depending on the environment in which they are implemented. The goal of the paper is reflected in the identification and presentation of critical success factors of projects implemented in family companies. The paper concludes with a discussion of the research results in relation to the existing, similar research studies, as well as with the announcement of future research, which will examine the conclusions drawn on a real sample.

    ENGLISH ABSTRACT: Manufacturing companies operate in a business environment where incremental growth may be achieved through expansion and renewal of existing plant and facilities. Effective management of the critical success factors of such capital development projects may also provide competitive advantage. These projects tend to be of a brown-field nature, characterised by a significant level of risk arising from the interaction between the project implementation and concurrent operation of the existing physical asset base. So it is vital to understand the factors that influence the success of capital expansion and renewal projects in the brown-field context. Although each project has unique features, there are critical success factors that can be customised for successful outcomes in the brown-field environment. This study identifies five critical success factors applicable to brown-field capital expansion and renewal projects. Managerial focus on the critical factors, and the prospects for successful brown-field projects, are discussed in the paper.

    To explore factors of human capital related to project success that employees expect from nurse managers. Human capital refers to those resources that managers working with projects possess, such as abilities, knowledge and qualities of character. The data were collected by open interviews (n=14) with nurses, public health nurses and nurse managers working in primary health care and a hospital. Data analysis was carried out using qualitative content analysis. The main factors of human capital related to project success proved to be as follows: (1) management of enthusiastic project culture, (2) management of regeneration and (3) management of emotional intelligence. Future research is needed on the kind of means nurse managers use in human capital management in projects and how they see their possibilities in managing human capital. Human capital management skills should be underlined as an important competence area when recruiting a nurse manager. The success of health care projects cannot be improved only through education or by training of nurse managers; in addition, projects need nurse managers who understand workplace spirituality and have high emotional intelligence. © 2011 The Authors.

    A success probability orientated optimization model for resource al ocation of the technological innovation multi-project system is studied. Based on the definition of the technological in-novation multi-project system, the leveling optimization of cost and success probability is set as the objective of resource al ocation. The cost function and the probability function of the optimization model are constructed. Then the objective function of the model is constructed and the solving process is explained. The model is applied to the resource al ocation of an enterprise’s technological innovation multi-project system. The results show that the pro-posed model is more effective in rational resource al ocation, and is more applicable in maximizing the utility of the technological innovation multi-project system.

    2014-11-01

    Evaluation is essential for the management of international projects or networks in health technology assessment (HTA). It extends beyond the normal process of project management by incorporating qualitative dimensions and provides information about a project's effectiveness and achievements. This article aimed to identify the factors that are important for the success of international HTA projects. The European network for Health Technology Assessment Joint Action (EUnetHTA JA) is presented as an exemplar. METHODS for the evaluation of international HTA projects include interviews, focus groups, questionnaires, observations and documentary review, and the key points of these approaches have been summarized. The impact and effectiveness of the EUnetHTA JA was evaluated by questionnaires of project participants and external stakeholders, and by documentary review. The response rate for the three annual questionnaires sent to project participants ranged from 86 percent to 88 percent and for external stakeholders ranged from 65 percent to 88 percent. Key factors for project success included production of deliverables according to the workplan, achievement of objectives, added value generated, effective communication, involvement of external stakeholders, workstream management and progress from the preceding EUnetHTA 2006-2008 project. The experience of this project can inform the evaluation of future international HTA collaborations, such as the EUnetHTA 2nd Joint Action and HTAsiaLink. A high response rate was achieved to the self-completion questionnaires and the strategy followed is recommended for evaluation of international HTA projects. Future assessments of international HTA projects should strive to measure outcomes and impact, not just outputs and process.

Full text of publication follows: This paper explores the history and lessons learned on the United States' Department of Energy's (DoE's) Fernald Closure Project - from the completion of the uranium-production mission to the implementation of the Records of Decision defining the cleanup standards and the remedies that were achieved. Cleaning up Fernald and returning it to the people of Ohio was a $4.4 billion dollar mega environmental-remediation project that was completed in October 2006. During a period of nearly 37 years, Fernald produced 250,000 tons of high-purity, low-enriched uranium for the U.S. defense program, generating more than six million tons of liquid and solid waste as it carried out its Cold War mission. The facility was shut down in 1989 and clean up began in 1992, when Fluor won the contract to clean up the site. The project comprised four phases: 1. Determining the extent of damage to the environment and groundwater at, and adjacent to, the production facilities 2. Selecting cleanup criteria - final end states that had to be met to protect human health and the environment 3. Selecting and implementing the remedial actions that would meet the cleanup goals 4. Doing the work safely, compliantly and cost-effectively. In the project's early stages, there were strained relationships and total distrust between the local community and the DOE as a result of aquifer contamination and potential health effects to the workers and local residents.

    Full Text Available Examining the interrelationships among critical success factors (CSFs for public private partnership (PPP projects is of importance for improving PPP project performance and maintaining the sustainability of PPP project implementation. Previous studies mostly focused on the identification of the CSFs for PPP projects; limited studies investigated the interrelationships among CSFs. Hence, the research objectives are (a to determine the interrelationships among CSFs of PPP projects taking into account the public and (b to identify influence paths contributing to take advantage of CSFs in the process of PPP implementation. A literature review and expert interviews were adopted to construct the CSFs framework; nine hypotheses were constructed and tested by the structural equation modelling (SEM based on the data collected from a questionnaire survey. This research reveals that the relationship between public and private partners is the leader-follower relationship, not the partnership relationship, in PPP projects, indicating that the responsibilities, power or resources existing among partners are very unequal. It also highlights that public involvement has a negative effect on the process of service provisions, and costs and risks exist in the process of public involvement in PPP projects. The determined interrelationships among CSFs will contribute to the sustainability and success of a PPP project.

    Directory of Open Access Journals (Sweden)

    Annie Maddison Warren

    2016-11-01

    Full Text Available Since the beginning of modern project management in the 1960s, academic researchers have sought to identify a definitive list of Critical Success Factors (CSFs, the key things that project managers must get right in order to deliver a successful product. With the advent of Information Technology (IT projects and, more recently, projects to deliver Enterprise Resource Planning (ERP systems, attention has turned to identifying definitive lists of CSFs for these more specific project types. The purpose of this paper is to take stock of this research effort by examining how thinking about each type of project has evolved over time, before producing a consolidated list of CSFs for each as a basis for comparison. This process reveals a high degree of similarity, leading to the conclusion that the goal of identifying a generic list of CSFs for project management has been achieved. Therefore, rather than continuing to describe lists of CSFs, researchers could increase the value of their contribution by taking a step forward and focusing on why, despite this apparent knowledge of how to ensure their success, ERP projects continue to fail.

    Full Text Available Success has always been the ultimate goal of construction projects, and different researchers have tried to evaluate it using different factors. Although specialized industrial construction usually involves very large scale projects with a high degree of technological complexity, research has mostly focused on civil and residential success factors. Experiences in Industrial Plants projects can help to improve project management and productivity in such a specialized sector. In this kind of projects, the contractual arrangement is one of the core differences on Project management and thus project success. This research seeks to develop a schema for classifying critical success factors as well as a methodology for evaluating projects. This methodology was adopted to evaluate critical success factors in Industrial Plants projects with different contractual arrangements. Findings suggest that although the construction stage has been the focus of many studies, the first stages are decisive for the success of projects; contract construction projects consider project planning to be more important; lump sum contract construction projects give greater importance to monitoring the benefits; bidding competition projects consider the available technology with greater rigor, etc. The results indicate that different Industrial Plants projects involve different success factors and management characteristics to achieve project objectives.En cualquier proyecto de construcción el principal objetivo es que sea exitoso y por lo tanto a lo largo del tiempo diferentes investigadores han tratado de evaluar los factores que influyen en el éxito de proyectos. En el ámbito de la construcción estas investigaciones se han enfocado principalmente a obras civiles y residenciales. Este artículo muestra resultados que provienen de proyectos de construcción industrial especializada que incluyen proyectos de gran escala con un alto grado de complejidad tecnol

    To identify the characteristics of successful research projects at an internal medicine residency program with an established research curriculum. The authors collected data about all research projects initiated by or involving medicine residents from 2006 to 2013 at Baystate Medical Center, using departmental files and institutional review board applications. Resident and mentor characteristics were determined using personnel files and Medline searches. Using multivariable models, the authors identified predictors of successful completion of projects using adjusted prevalence ratios (PRs). The primary outcome was manuscript publication by resident and secondary outcome was either publication or regional/national presentation. Finally, residents were surveyed to identify barriers and/or factors contributing to project completion. Ninety-four research projects were identified: 52 (55.3%) projects achieved the primary outcome and 72 (76.5%) met the secondary outcome, with overlap between categories. Most study designs were cross-sectional (41, 43.6%) or retrospective cohort (30, 31.9%). After adjustment, utilization of the epidemiology/biostatistical core (PR = 2.09; 95% CI: 1.36, 3.21), established publication record of resident (PR = 1.54, 95% CI: 1.14, 2.07), and resident with U.S. medical education (PR = 1.39, 95% CI: 1.02, 1.90) were associated with successful completion of projects. Mentor publication record (PR = 3.13) did not retain significance due to small sample size. Most respondents (65%) cited "lack of time" as a major project barrier. Programs seeking to increase resident publications should consider an institutional epidemiology/biostatistical core available to all residency research projects, and residents should choose experienced mentors with a track record of publications.

    The Qinshan Phase III (CANDU) Project, the largest-scale cooperative project between China and Canada, was completed in 2003 well in advance of the schedule and 10% under budget. The Third Qinshan (Phase III) Nuclear Power Plant (TQNPP) was built in record times: Unit 1 achieved commercial operation on December 31, 2002 and Unit 2 on July 20, 2003, 43 days and 115 days ahead of schedule respectively. Improvements in design and construction methods allowed Unit 1 to be constructed in 51.5 months from First Concrete to Criticality - a record in China for nuclear power plants. The key factors are project management and project management tools, quality assurance, construction methods, electronic documentation with configuration control that provides up-to-date on-line information, CADDS design linked with material management and control. New design and construction techniques were introduced by combining conventional AECL practices with working experiences in China. The most advanced tools and techniques for achieving optimum construction quality, schedule and cost were used. Successful application of advanced project management methods and tools has benefited TQNPC in its subsequent plant operation, and the Chinese contractors in advancing their capabilities in future nuclear projects in China as well as enhancing their opportunities internationally. Excellent co-operation and teamwork within the integrated TQNPC/AECL Commissioning Team with well documented QA program, process and procedures also contributed to the remarkable success of the Project. AECL's initial assessment, based on lessons learned, showed that the project schedule could readily be reduced to 66 months and the capital costs reduced by 25% for a replication project. AECL is building on this experience and successful results of TQNPP in its Advanced CANDU Reactor TM (ACR TM ) ** design. (authors)

    2016-06-01

    Full Text Available The implementation of public private partnership (PPP procurement method is expected to help governments in the development of infrastructures and provides an opportunity for the reduction in the governments’ debt profiles. This method has been adopted in Nigeria for more than a decade and with these years of implementation, few infrastructural projects have been developed using this method while some have been unsuccessful. This study aims to examine the PPP projects implementation in Nigeria and identify the most critical factors that could determine the success of such projects. A total of 184 questionnaires were received from public and private sectors’ participants in the implementation of PPP projects. An exploratory factor analysis identified seven critical success factors as projects feedback, leadership focus, risk allocation and economic policy, good governance and political support, short construction period, favourable socio-economic factors, and delivering publicly needed service. This study shows that more developmental projects could be delivered through PPP if the government could focus on these main factors in the implementation process. The result will influence policy development towards PPP and guide the partners in the development of PPP projects.

  13. Management of Interface between Main Contractor and Subcontractors for Successful Project Outcomes

    Directory of Open Access Journals (Sweden)

    Harry White

    2014-01-01

    Full Text Available There has been increased dependence on subcontracting within the construction industry, the operational relationship between the Main Contractor (MC and Subcontractor (SC plays a significant role in successful delivery of projects. Through the literature review this paper argues that despite SCs bring added value to construction projects, the increased reliance on SCs has strained relationships between the MC and SC. Also MCs are more concerned with risk and price reduction which undermine the relationship heavily. Current practices in the construction industry in managing SCs were evaluated through a case study and semi-structured interviews. A questionnaire survey was used to investigate the ways of facilitating the interface between the MC and SC in general. The study highlighted that prevailing adverse relationships and culture in the industry are influencing the success of construction projects. The lack of trust is a key factor affecting the relationships between MC and SCs. However, the proactive involvement of the MC with SCs in maintaining continuity of the team from procurement to construction stage and transparency in the processes were key success factors for successful completion of the project.

    Collaborative partnerships are critical to achieving health equity. As such, it is important to understand what contributes to the success of such partnerships. This paper describes the Alaska Fourth R collaborative, a multisectoral group of agencies (including education, health and human services, the violence against women sector, the governor's council on domestic violence, and an external evaluator) that successfully planned, implemented and evaluated a multi-focus health education program statewide. The purpose of this paper was to explore the ways in which seven pre-identified factors contributed to the successful achievement of the collaborative's goals. This project was grounded in community-based research principles, and collectively, the group chose to use Roussos and Fawcett's (2000) seven-factor model as the basis for the project. Using this model as a guide, semi-structured interviews were conducted with five leaders from the key organizations in the collaborative. In interviews, stakeholders described how each of the seven factors functioned in the Alaska collaborative to contribute to project success, with a particular focus on the critical role of relationships. Three specific relationship facets emerged as cross-cutting themes: flexibility, transparency, and prioritization. In sum, taking the time to build deep and authentic relationships, and then developing a shared vision and mission within the context of relationships that are flexible, transparent and prioritized, provided a strong foundation for future success in this collaborative.

    The Los Alamos National Laboratory (the Laboratory) Chemistry and Metallurgy Research (CMR) Facility, constructed in 1952, is currently under going a major, multi-year demolition and construction project. Many of the operations required under this project (i.e., design, demolition, decontamination, construction, and waste management) mimic the processes required of a large scale decontamination and decommissioning (D and D) job and are identical to the requirements of any of several upgrades projects anticipated for the laboratory and other Department of Energy (DOE) sites. For these reasons the CMR upgrades Project is seen as an ideal model facility--to test the application and measure the success of waste minimization techniques which could be implemented for any similar projects. The purpose of this paper will be to discuss the successful completion of a waste stream analysis. The analyses performed was to measure the potential impact of waste generation, in terms of volume and costs, for a reconfiguration option being considered to change the approach and execution of the original project

  18. Success Stories in Radiotherapy Development Projects: Lessons Learned from Radiotherapy Development Projects. Chapter 29

    Zubizarreta, E.; Van Der Merwe, D.

    2017-01-01

    This chapter examines some problems found to be common in the process of setting up, running or expanding radiotherapy facilities. The establishment of radiotherapy services is essential to consolidate any national cancer control plan. In other words, such a plan cannot exist without radiotherapy. The IAEA guidance on setting up a radiotherapy programme covering the clinical, medical physics, radiation protection and safety aspects gives an estimate of one teletherapy machine needed per million population]. The IAEA’s Directory of Radiotherapy Centres (DIRAC) shows that the number of megavoltage (MV) machines per million population varies from 8.2 in the United States of America to 5.5 in western Europe. There are still many countries without a single radiotherapy department, especially in Africa, and many others have very low coverage, e.g. up to one external beam radiotherapy machine to cover a population of 35 million, which is close to having no coverage. There are many possible reasons for this situation. In many low income countries, the combination of lower life expectancy, low income taxes, a small budget for public health, and unmet basic needs such as housing, prevention and/or treatment of infectious diseases (malaria, tuberculosis, human immunodeficiency virus (HIV), diarrhoea), drinkable water and sewerage makes the cancer control problem a lower priority. The indicators shown illustrate these points. Establishing a radiotherapy programme requires careful planning, including the requirement for successive phases. Resources should be available for designing, building, purchasing, maintaining and replacing equipment, and for providing training in its use. In the case of a first radiotherapy facility with basic staffing levels, there is not likely to be enough expertise to guide and oversee the process in many or all of these areas.

    Full Text Available Issues that dominate the construction industry for the long time such as time overrun, cost overrun, quality of construction and also safety during the construction process are difficult to resolve because of several factors involved which amongst them are leadership quality in the industry. Solving these issues can make the industry more sustainable in nature. This paper presents the need of leadership quality among construction parties involved to steer a construction project successfully. Literature work found that 11 leadership qualities to ensure construction project success. From the frequency analysis, five most dominant leadership qualities are team building, communication skill, visioning, planning & strategy skill, and decision making. Beside the literature, this study also seeks an opinion from a senior leader of a successful construction company regarding the need of these qualities amongst parties to resolve the construction issues. The results from an interview session indicate that he fully agreed with the need of all the qualities in the construction industry. This shows that there is a strong relationship between solving the issues with the leadership quality in ensuring construction project success. These qualities should be further investigated to acquire a better representation of leadership quality in resolving construction issues for Malaysia construction industry.

    Our findings indicate that managers perceive the marketplace in multiple ways during the NPD process and also that differences exist in metric equivalence across successful and unsuccessful NPD projects. Also, although half of the marketplace variables are positively related to NPD success, managers in Finnish technology companies appear to attach higher relative importance to market attractiveness rather than market competitiveness variables. Marketplace variables appear to be less important than in the Korean and Chinese samples, and much more important than  in the Canadian sample in the Mishra et all study (1996, and similarly much more important than in the Cooper study (1979b.

    Over the past 26 years, several factors have contributed to INVAP's projection into domestic and overseas operations. Of these, the most recognized is of course the technological capabilities INVAP keeps developing to satisfy our customer's requirements. In a second thought, the other factor is the strategic objective of providing specific purpose customer oriented solutions. The less obvious third important factor in this trilogy is the successful application of Project Management techniques and methods. INVAP's vision on Project Management encompasses well known concepts as: Integrated Management, Proactive solutions, Cost Control and Reporting, Quality Assurance, Target Schedules, Performance Requirements, Risk Management, Configuration Management and Integrated Logistic Support. After 2 years of execution of the Replacement Research Reactor Project for the Australian Nuclear Science and Technology Organization, our Project Management methodology have allowed us to timely meet all project milestones, complete basic and detail engineering, timely deliver the preliminary safety reports, manufacture and test technological concepts in specifically built mock ups and overcome risky situations -like the economical panorama in Argentina- without jeopardizing our Contractual commitments. Present paper depicts the practical approach INVAP has for Project Management -particularly within the Nuclear Division-, and a description of the tools to such aim developed. (author)

  4. Privatization Financing Alternatives: Blending Private Capital and Public Resources for a Successful Project

    1998-10-19

    The U.S. Department of Energy (DOE) launched the Contract Reform Initiative in 1994 in order to improve the effectiveness and effkiency of managing major projects and programs. The intent of this initiative is to help DOE harness both technical and market forces to reduce the overall cost of accomplishing DOE's program goals. The new approach transfers greater risk to private contractors in order to develop incentives that align contractor performance with DOE's objectives. In some cases, this goal can be achieved through public-private partnerships wherein the govermhent and the contractor share risks associated with a project in a way that optimizes its economics. Generally, this requires that project risks are allocated to the party best equipped to manage and/or underwrite them. While the merits of privatization are well documented, the question of how privatized services should be financed is often debated. Given the cost of private sector equity and debt, it is difficult to ignore the lure of the government's "risk free" cost of capital. However, the source of financing for a project is an integral part of its overall risk allocation, and therefore, participation by the government as a financing source could alter the allocation of risks in the project, diminishing the incentive structure. Since the government's participation in the project's financing often can be a requirement for financial feasibility, the dilemma of structuring a role for the government without undermining the success of the project is a common and difficult challenge faced by policymakers around the world. However, before reverting to a traditional procurement approach where the government enters into a cost-plus risk profile, the government should exhaust all options that keep the private entity at risk for important aspects of the project. Government participation in a project can include a broad range of options and can be applied with precision to bridge a

    Full Text Available To achieve the objectives of continuous improvement programs, construction managers must link the achievement of quality with cost. This paper aims to associate project management success (PMS with cost of control (COC activities in an empirical manner. Thus, the purpose is to determine the extent to which COC activities impact PMS. Quantitative method was adopted to collect data from Malaysian building companies using postal and email surveys. Hypothesis is tested using correlation and simple linear regression analysis. The findings of this study indicate that COC activities are positively associated with the PMS. The empirical evidences obtained from this research, provides financial justification for all quality improvement efforts. This can assist building contractors to enhance the success of project management by reducing the level of business failures due to poor quality, cost overruns, and delays.

    The elements that determine the success of development projects on goats and the prerequisites for ensuring this are discussed in the context of the bewildering diversity of goat genetic resources, production systems, multifunctionality, and opportunities for responding to constraints for productivity enhancement. Key determinants for the success of pro-poor projects are the imperatives of realistic project design, resolution of priorities and positive impacts to increase investments and spur agricultural growth, and appropriate policy. Throughout the developing world, there exist 97% of the total world population of 921 million goats across all agro-ecological zones (AEZs), including 570 breeds and 64% share of the breeds. They occupy a very important biological and socio-economic niche in farming systems making significant multifunctional contributions especially to food, nutrition and financial security, stability of farm households, and survival of the poor in the rural areas. Definitions are given of successful and failed projects. The analyses highlighted in successful projects the value of strong participatory efforts with farmers and climate change. Climate change effects on goats are inevitable and are mediated through heat stress, type of AEZ, water availability, quantity and quality of the available feed resources and type of production system. Within the prevailing production systems, improved integrated tree crops - ruminant systems are underestimated and are an important pathway to enhance C sequestration. Key development strategies and opportunities for research and development (R and D) are enormous, and include inter alia defining a policy framework, resolution of priority constraints using systems perspectives and community-based participatory activities, application of yield-enhancing technologies, intensification, scaling up, and impacts.

    Full Text Available E-government implementations in developing countries still face difficulties, leading to a large failure ratio. This is too high a cost for developing countries. Analysis of the reasons behind success and failure of e-government projects is still an interesting domain of investigation. Several approaches were advanced and success and failure factors have been stipulated, but factors pertinent to Public Administration have yet to be investigated and analyzed. This work builds on the results of earlier research, analyzing the factors behind the change in performance of the different sites of a specific project, reasons of their original success, and the relapse of one site. It reviews in detail the factors advanced by previous works and integrates for the first time the results obtained by 3 different research methodologies. It clarifies the causality between different factors presumed to individually affect the e-government implementations, thus enabling the disambiguation between the main and secondary less effective causes of failure. The success and failure factors significance and relative importance are identified, revealing the recommended track of action for the set-back remedy.

    2016-02-01

    The Citizen School Project (Escola Cidadã) was implemented from 1993 to 2004 in Porto Alegre, capital of the Brazilian state of Rio Grande do Sul. This article presents the conception behind the Citizen School Project, the basic mechanisms created to implement and evaluate its strengths and weaknesses, and some of its contradictions. After contextualising the educational reforms in Brazil during the 1980s and 1990s, the authors demonstrate how the Citizen School Project's emphasis on participation and democratisation was a radical departure from Brazil's traditional public education system. Next, they present the three main goals and structures of the Citizen School Project - democratisation of access to schools, democratisation of schools' administration, and democratisation of access to knowledge. They conclude by discussing some pedagogic, social and political dynamics which appear to be strong legacies of this pedagogical project. The authors also argue that the Citizen School Project has both improved the quality of education in Porto Alegre and is an important contribution to our collective thinking about the politics of "successful" educational policies.

    As part of the component development of TsAGI’s new subsonic wind tunnel where the air flow velocity in the closed test section is up to 160 m/sec hydraulic and thermal characteristics of air cooler are calculated. The air cooler is one of the most important components due to its highest hydraulic resistance in the whole wind tunnel design. It is important to minimize its hydraulic resistance to ensure the energy efficiency of wind tunnel fans and the cost-cutting of tests. On the other hand the air cooler is to assure the efficient cooling of air flow in such a manner as to maintain the temperature below 40 °C for seamless operation of measuring equipment. Therefore the relevance of this project is driven by the need to develop the air cooler that would demonstrate low hydraulic resistance of air and high thermal effectiveness of heat exchanging surfaces; insofar as the cooling section must be given up per unit time with the amount of heat Q=30 MW according to preliminary evaluations. On basis of calculation research some variants of air cooler designs are proposed including elliptical tubes, round tubes, and lateral plate-like fins. These designs differ by the number of tubes and plates, geometrical characteristics and the material of finned surfaces (aluminium or cooper). Due to the choice of component configurations a high thermal effectiveness is achieved for finned surfaces. The obtained results form the basis of R&D support in designing the new subsonic wind tunnel.

    In recent years, the development of geothermal plants in Germany has increased significantly due to a favorable political setting and resulting financial incentives. However, most projects are developed by local communities or private investors, which cannot afford a project to fail. To cover the risk of total loss if the geothermal well should not provide the energy output necessary for an economically viable project, investors try to procure insurances for this worst case scenario. In order to issue such insurances, the insurance companies insist on so called probability-of-success studies (POS studies), in which the geological risk for not achieving the necessary temperatures and/or flow rates for an economically successful project is quantified. Quantifying the probability of reaching a minimum temperature, which has to be defined by the project investors, is relatively straight forward as subsurface temperatures in Germany are comparatively well known due tens of thousands of hydrocarbon wells. Moreover, for the German Molasse Basin a method to characterize the hydraulic potential of a site based on pump test analysis has been developed and refined in recent years. However, to quantify the probability of reaching a given flow rate with a given drawdown is much more challenging in areas where pump test data are generally not available (e.g. the North German Basin). Therefore, a new method based on log and core derived porosity and permeability data was developed to quantify the geological risk of reaching a determined flow rate in such areas. We present both methods for POS studies and show how subsurface data such as pump tests or log and core measurements can be used to predict the chances of a potential geothermal project from a geological point of view.

The field research involved 415 projects from nine different economic sectors. Data was gathered through a questionnaire applied to managers and project team members. Results showed that there are significant and positive impacts in the adoption of Risk Management practices on project success. It also showed that there is dependence between perceived success and the presence/absence of a risk manager, i.e., the presence of a risk manager has positive impacts on project success. The major limitation of this study concerns the methodological choice: non-probability sample survey based on respondents perception. The work promotes the integration between Risk Management practices and projects performance

  17. Nonlinear interaction model of subsonic jet noise.

    2008-08-13

    Noise generation in a subsonic round jet is studied by a simplified model, in which nonlinear interactions of spatially evolving instability modes lead to the radiation of sound. The spatial mode evolution is computed using linear parabolized stability equations. Nonlinear interactions are found on a mode-by-mode basis and the sound radiation characteristics are determined by solution of the Lilley-Goldstein equation. Since mode interactions are computed explicitly, it is possible to find their relative importance for sound radiation. The method is applied to a single stream jet for which experimental data are available. The model gives Strouhal numbers of 0.45 for the most amplified waves in the jet and 0.19 for the dominant sound radiation. While in near field axisymmetric and the first azimuthal modes are both important, far-field sound is predominantly axisymmetric. These results are in close correspondence with experiment, suggesting that the simplified model is capturing at least some of the important mechanisms of subsonic jet noise.

    The Department of Energy (DOE) at the Fernald Environmental Management Project (FEMP), near Cincinnati, Ohio, has successfully impacted the safety, cost and schedule goals of the Decontamination and Dismantling (D ampersand D) Program by using the art of implosions. An implosion is the act of bringing a structure down in a well planned and directed manner using explosive materials. Three major structures in three separate projects were imploded using this well known commercial technology. Safety is, and will always be, the major consideration with each of the projects. As each project succeeded another, the work process used new and improved methods to lower the risk to the environment, provide a safer workplace by reducing the exposure of high risk work and reducing the spread of lead, asbestos and radioactive materials. The time frame for dismantlement of the steel structures was greatly improved, thus reducing the total project cost. The lessons learned were incorporated from one project to another, to continually improve the work process. A number of alternatives were considered for the removal of the structures, seven, four and three stories in height. The subcontractor and its demolition sub-tier contractor worked in a fixed price lump sum contract environment. While skeptical at first, the subcontractor realized the benefits of the technology, a win-win situation for all participants. The overall planning of each of the events was tied to the needs of the client (DOE), the stakeholders and the community surrounding the site, and the continuing progress at the Fernald site. The recording and application of several key lessons learned in the sequence of implosions, will be the key issues of interest in this paper. Each project offered interesting opportunities for contingency planning, coordination, safety culture adjustments, and high regard for the protection of surrounding structures

  3. Projected near-future levels of temperature and pCO2 reduce coral fertilization success.

    Directory of Open Access Journals (Sweden)

    Full Text Available Increases in atmospheric carbon dioxide (pCO2 are projected to contribute to a 1.1-6.4°C rise in global average surface temperatures and a 0.14-0.35 reduction in the average pH of the global surface ocean by 2100. If realized, these changes are expected to have negative consequences for reef-building corals including increased frequency and severity of coral bleaching and reduced rates of calcification and reef accretion. Much less is known regarding the independent and combined effects of temperature and pCO2 on critical early life history processes such as fertilization. Here we show that increases in temperature (+3°C and pCO2 (+400 µatm projected for this century negatively impact fertilization success of a common Indo-Pacific coral species, Acropora tenuis. While maximum fertilization did not differ among treatments, the sperm concentration required to obtain 50% of maximum fertilization increased 6- to 8- fold with the addition of a single factor (temperature or CO2 and nearly 50- fold when both factors interact. Our results indicate that near-future changes in temperature and pCO2 narrow the range of sperm concentrations that are capable of yielding high fertilization success in A. tenuis. Increased sperm limitation, in conjunction with adult population decline, may have severe consequences for coral reproductive success. Impaired sexual reproduction will further challenge corals by inhibiting population recovery and adaptation potential.

    A successful fieldwide CO{sub 2} miscible gas injection project has been underway at the East Vacuum Grayburg San Andres Unit (EVGSAU) in eastern New Mexico, USA since 1985. This presentation follows the evolution of CO{sub 2} miscible gas WAG injection operations at EVGSAU and discusses some of the significant changes in reservoir strategy management which have been implemented over the past 13 years. These changes parallel the evolution in the industry's understanding of and experience with CO{sub 2} miscible gs injection processes. The operating problems and reservoir management challenges encountered at East Vacuum - injection performance, sweep efficiency, effective management of WAG operations, rapidly changing requirements for handling produced gas, and maintaining efficient utilization of injected CO{sub 2} - reflect the kinds of challenges typically encountered in managing a large CO{sub 2} injection project. 1 fig., 1 tab.

    Pay for success (PFS) is a type of social impact investing that uses private capital to finance proven prevention programs that help a government reduce public expenditures or achieve greater value. We conducted an analysis of the first eleven PFS projects in the United States to investigate the potential of PFS as a strategy for financing and disseminating interventions aimed at improving population health and health equity. The PFS approach has significant potential for bringing private-sector resources to interventions regarding social determinants of health. Nonetheless, a number of challenges remain, including structuring PFS initiatives so that optimal prevention benefits can be achieved and ensuring that PFS interventions and evaluation designs are based on rigorous research principles. In addition, increased policy attention regarding key PFS payout issues is needed, including the "wrong pockets" problem and legal barriers to using federal Medicaid funds as an investor payout source.

    Measuring project success level is a challenging activity. This area of works has attracted many researchers to look deeper into the method of measurement, success factor identification, risk management, and many others relevant topics. However, the project management scope is limited until the project handover stage. After a project handover, the control of a project management changes from Project Management Team to the project owner/commercialization team. From an investor’s point of view, the success of a project delivery needs to be followed by the success of commercialization phase. This paper aims to present an approach on how we track and measure the progress and success level of a project investment in the commercialization phase. This is an interesting topic which probably often being forgotten in many practical case. Our proposed concept modify Freeman and Beale concept by estimating the variance between the Planned Net Present Value / Annual Worth (as it is in the Feasibility Study Document) and the Actual Net Present Value / Annual Worth (until the point time of evaluation). The gap will lead us to the next analysis and give us some important information, especially exposing whether our project investment performs better than the planning or underperformed. Some corrective actions can be suggested based on the provided information. Practical cases to exercise the concept is also provided and discussed; one case in a property sector in the middle of commercialization phase, and another case in a Power Plant investment approaching the end of commercialization phase.

  9. An empirical study on the critical success factors of small to medium sized projects in a South African mining company

    2014-08-01

    Full Text Available Projects that fail, for whatever reason, can impact negatively on society, organisations, and other stakeholders. A number of researchers have identified various critical success factors (CSFs that can influence the outcome and success of a project. This research therefore aims to determine the CSFs that influence various success measures of small- to medium-sized projects at a South African mining company, Exxaro Resources’ Grootegeluk Coal Mine. Other objectives of this research include determining the extent of the impacts of these CSFs on the different success measures of a project. The investigation suggests that there are correlations among CSFs, and that certain factors impact the outcome of projects far more than others. This research finds that the single most important CSF for small- to medium-sized projects is the selection of a competent project manager. The competent project manager is characterised by a group of interrelated CSF factors: good leadership, commitment, and learning from past experiences. Based on the research results, other CSFs are discussed and explored in order for recommendations to be made on how this mining company, and possibly other organisations, can achieve greater project success.

    China has 800,000 villages-one person out of seven on the globe is living in a Chinese rural settlement. Yet the global discussions about the situation in China is currently characterised by a disproportionate focus on the development of towns and until now circumstances have generally been neglected in the rural areas, where 70% of the Chinese population is still living. Within the 5 years of the SUCCESS project research, this set of actual problems has been considered and analysed under the principle of sustainability: "What to maintain?" "What to change?" were the overall research questions asked in the SUCCESS project; the researchers were looking for answers under a sustainability regime, respecting the need to raise the quality of life in the villages. Several interweaving processes were used to achieve results: the inter-disciplinary research process between many areas of expertise, the trans-disciplinary process between the researchers and the Chinese villagers, and a negotiation process that made the connection between these two processes. The introduction describes the basic sustainability definition that was orienting the whole study. The innovation lays mostly in the methodology: the inter-disciplinary research co-operation related to practice and to involving the affected communities is needed to manage the significant and growing imbalances between urban and rural areas regarding their sustainability. In the transdisciplinary work, the project developed "village future sentences" that describe the local outcome of the research as one step towards better theoretical understanding of the mechanisms that could lead to a sustainable future, and they also managed to start sustainability processes in the case study sites. The integrated approach of the project helped generating future scenarios for these villages covering all aspects of their development, including urban design issues. Out of these scenarios, the villages developed small projects that could

    Directory of Open Access Journals (Sweden)

    Sandra K Znajda

    2014-01-01

    Full Text Available The lack of clear indications of success in integrated conservation and development projects has resulted in strong criticisms of these projects, and a call for the return to conservation activities that exclude local communities. Impeding this discussion is the lack of clarity around how project success is defined and measured in conservation and development projects, especially in terms of development goals. This study involved an in-depth exploration of two agroforestry-focused conservation and development projects in Nicaragua to provide insights into how success in reaching development goals is interpreted in such projects. In both projects, development was equated with increased household income, in contrast to more contemporary definitions that include aspects such as self-respect and social integration. Both projects in turn relied on income as a measure of development success, which ultimately lessened attention to impacts not easily measured quantitatively as well as participant perspectives on desired goals. The paper concludes with a discussion of implications for conservation practitioners; specifically the need for better alignment of project goals with contemporary explanations of development, and a need to move beyond primarily numerical indicators to measure change through an interdisciplinary approach in order to have a more comprehensive understanding of project impacts.

    Although the Three Gorges Project (TGP) may have affected the population structure and distribution of plant and animal communities, few studies have analyzed the effect of this project on small mammal communities. Therefore, the present paper compares the small mammal communities inhabiting the beaches of Dongting Lake using field investigations spanning a 20-year period, both before and after the TGP was implemented. Snap traps were used throughout the census. The results indicate that the TGP caused major changes to the structure of the small mammal community at a lake downstream of the dam. First, species abundance on the beaches increased after the project commenced. The striped field mouse (Apodemus agrarius) and the Norway rat (Rattus norvegicus), which rarely inhabited the beach before the TGP, became abundant (with marked population growth) once water was impounded by the Three Gorges Reservoir. Second, dominant species concentration indices exhibited a stepwise decline, indicating that the community structure changed from a single dominant species to a more diverse species mix after TGP implementation. Third, the regulation of water discharge release by the TGP might have caused an increase in the species diversity of the animal community on the beaches. A significant difference in diversity indices was obtained before and after the TGP operation. Similarity indices also indicate a gradual increase in species numbers. Hence, a long-term project should be established to monitor the population fluctuations of the Yangtze vole (Microtus fortis), the striped field mouse and the Norway rat to safeguard against population outbreaks (similar to the Yangtze vole outbreak in 2007), which could cause crop damage to adjacent farmland, in addition to documenting the succession process of the small mammal community inhabiting the beaches of Dongting Lake. © 2013 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley

    A numerical method for computing the subsonic flow around multi-element airfoil systems was developed, allowing for flow separation at one or more elements. Besides multiple rear separation also sort bubbles on the upper surface and cove bubbles can approximately be taken into account. Also, compressibility effects for pure subsonic flow are approximately accounted for. After presentation the method is applied to several examples and improved in some details. Finally, the present limitations and desirable extensions are discussed.

    Full Text Available IT projects hold a huge importance to economic growth. Today, half of the capital investments are in IT technology. IT systems and projects are extensive and time consuming; thus implying that its failure is not affordable, so proper feasibility study of assessing project success factors is required. A current methodology like Fuzzy Cognitive Maps has been experimented for identifying and evaluating the success factors in IT projects, but this technique has certain limitations. This paper discusses two new approaches to evaluate IT project success: Extended Fuzzy Cognitive Maps (E-FCM & Neutrosophic Cognitive Maps (NCM.The limitations of FCM like non consideration for non-linear, conditional, time delay weights and indeterminate relations are targeted using E-FCM and NCM in this paper.

    The purpose of this article is to describe a collaborative project designed to recruit and retain students from underrepresented minorities and disadvantaged backgrounds into nursing education. Ethnic minorities remain underrepresented in the nursing workforce in comparison to the general population. The numbers of minorities enrolled in nursing education programs are insufficient to meet the health care workforce diversity needs of the future. High school students were provided with a preprofessional education program to prepare them for admission into a nursing program. Retention strategies were implemented for newly admitted and enrolled nursing education students. Twenty-one high school students enrolled in a nursing education program. The students enrolled in the nursing education program graduated and passed the licensure examination. Early recruitment and multiprong retention programs can be successful in diversifying the registered nurse workforce.

    This paper discusses the successful completion of a RCRA (Resource Conservation and Recovery Act) closure of a HF (hydrofluoric acid) tank car at FEMP, which is on the national priorities list of hazardous waste sites and is undergoing CERCLA remediation. The HF tank car closure was conducted by FERMCO. Through a combination of sound planning and team work, the HF tank car was closed safely and ahead of schedule. During > 22,000 hr field work required for construction modifications and neutralization of 9,600 gallons of HF and decontamination rinseates, there were no OSHA recordable incidents. The system design avoided additional costs by maximizing use of existing equipment and facilities. This successful closure of the HF tank car demonstrates FEMP's commitment to reducing risks and cleaning up the facility in a manner consistent with objectives of RCRA regulations and the Ohio EPA hazardous waste rules. This in turn facilitated ongoing negotiations with Ohio EPA to integrate RCRA closure and the ongoing CERCLA remediation activities. This paper addresses why the unit was clean closed under an approved RCRA Closure Plan. Integration of EPA regulations for RCRA and CERCLA programs and the DOE-Orders impacting design, construction and operation of an acid neutralization system is also reviewed. The paper concludes with a discussion of lessons learned in the process in preparing the closure plant and through final project close out

    Successful research management requirements include; equal teamwork and efficient coordination, in order to increase the impact of the research outcomes and provide added value knowledge. Aim of this paper is to discuss the strategies that have been followed during the RN4CAST study, the largest nursing multi-country research project ever conducted in Europe. The paper focuses on the core research strategies rather than on the administrative activities, which are inevitably also required for the success of a large scale research. This paper is an extension of a conference presentation in the International Conference of the European Federation for Medical Informatics (MIE) 2011 in Oslo, and was subsequently published in the Studies in Health Technology and Informatics book series (IOS Press) under the title "Research management: the case of RN4CAST." Management of a multicountry nursing survey requires the use of common data collection tools, applicable to every context, research protocols supporting the scope of the research, data models for multi-country analyses and global dissemination strategies. Challenges that may be faced during the implementation of the study include the individualized confrontation of obstacles during data collection, the coherence of national procedures (for example permissions for data collection) in European level, and the challenge to gain information of added value for the EU, by aggregating the national survey results through a powerful data analysis model. Communication strategies are also discussed.

    The energy change is the most important common work of the German after-war history. And it offers a unique collective field of learning, how the socio-ecological transformation can be converted in practice. If the energy change succeeds in an industrial country like Germany, many other countries can follow this example. The Bund fuer Umwelt und Naturschutz Deutschland (BUND) and the Vereinigung Deutscher Wissenschaftler (VDW) show as editors, what now must be done in order that the energy change becomes a success. Because currently threatens the energy change to be slowed down by the policy and talked to death by many stakeholders in the industry. This book demonstrates why the energy change is necessary and how it can succeed. It shows what has to be done and wants to use the existing enthusiasm in order to lead the common project energy change jointly to success. What is needed is a long-term policy that finally takes the reduction of energy consumption in attack.

The growth of human presence in its surroundings during the last three decades, has caused the right-of-way to be totally confined by luxury housing developments, streets, highways and resorts, as well as by the local communities and their activities, schools, and commerce. The pipeline runs through the Serra do Mar unstable mountain range slopes, with sequences of very steep hills and ravines followed by swamps and rivers. The success of such a challenging project - assembling the new line in a narrow ROW with all its restrictions, where the old line was still in operation, and complying with the tight work schedule required by PETROBRAS, was only possible due to a carefully managed combination of: accurate planning, best engineering methods and equipment and experienced workforce, deeply integrated in a massive effort towards safety, environmental care and social responsibility.

  2. The project on site - setting the scene for successful industrial relations

    The site construction performance at Torness and Heysham 2 has been described in various other papers during the Conference and in common with other large projects undertaken over the last 20 years a final judgement will be made as to whether, in simple terms, they were ''good'' or ''bad'' sites. Although there are many individuals or organisations who may make this judgement, it is unlikely that the basic conclusion will differ. What may differ however is the list of reasons that will be advanced to explain the final result. Looking at the investigations made into past projects, the reasons advanced for their success or otherwise can range from the geographical location of the site to material delivery problems, design changes, safety issues, or even the state of the overall national economic climate during the period under scrutiny. Where industrial relations problems are singled out, they can usually be linked to one or more of the factors mentioned. When looking at the complexity of projects such as Torness and Heysham, it is to be expected that unlooked for difficulties and problems will always arise but it is equally true that there is sufficient experience and expertise available in the industry for many possible problem areas to be anticipated and ''designed'' out before work even commences on site. This paper will be looking at the clients' role in creating a suitable environment for contractors to fully manage all aspects of their site operation and to ensure that acute problems can receive the full attention of all parties and not have to be set against a continuing background of unnecessary irritations.

  3. IUE project comes to an end after 18+ years of extremely successful orbital operations

    Science.gov (United States)

    1996-08-01

    At a meeting of the Science Programme Committee (SPC) of the European Space Agency (ESA) in February, the decision was taken to terminate the orbital operations of the International Ultraviolet Explorer (IUE) satellite on September 30. Science operations will terminate shortly before that date to allow the necessary end-of-life testing of the spacecraft. Only a year ago, when NASA - the major partner in the IUE project - decided to terminate its IUE science operations, ESA had been able to extend its support to include full responsibility for the scientific operations, under the "hybrid science operations" scheme, and thus maintain this important capability for the astrophysics community. As a consequence of the budgetary restrictions placed on ESA's Science Programme, the earlier recommendation of the Space Science Advisory Committee (SSAC), to terminate the operations of IUE in coordination with NASA in September, was accepted by the SPC. The IUE project, using a 45cm ultraviolet telescope for spectroscopic observations in the waveband 115 to 320 nm, has been carried out jointly by NASA, ESA and the British PPARC (formerly SERC). Launched in 1978, its designed lifetime was only three years. In July, the SPC agreed to complete the IUE Final Archive by the end of 1997, allowing the project to reprocess all its spectroscopic observations (numbering over 100,000) with a newly designed reduction, significantly improving on the normal direct processing done during the operational phase of the IUE project. The resulting homogeneous data archive on the ultraviolet radiation of cosmic sources, collected over the 18+ years of the operational project, will remain an important resource for astrophysical studies for many years to come. This has been one of the most successful astrophysics projects in space science, with more than 3,500 papers in refereed journals based on the observational results of the spectrographs. Over 500 doctoral dissertations have used its results

    The present study deals with development and validation of a fully explicit, compressible Runge-Kutta-4 (RK4) Navier-Stokes solver in the opensource CFD programming environment OpenFOAM. The background motivation is to shift towards explicit density based solution strategy and thereby avoid using the pressure based algorithms which are currently proposed in the standard OpenFOAM release for Large-Eddy Simulation (LES). This shift is considered necessary in strongly compressible flows when Ma > 0.5. Our application of interest is related to the pre-mixing stage in direct injection gas engines where high injection pressures are typically utilized. First, the developed flow solver is discussed and validated. Then, the implementation of subsonic inflow conditions using a forcing region in combination with a simplified nozzle geometry is discussed and validated. After this, LES of mixing in compressible, round jets at Ma = 0.3, 0.5 and 0.65 are carried out. Respectively, the Reynolds numbers of the jets correspond to Re = 6000, 10000 and 13000. Results for two meshes are presented. The results imply that the present solver produces turbulent structures, resolves a range of turbulent eddy frequencies and gives also mesh independent results within satisfactory limits for mean flow and turbulence statistics.

    Within the context of the Heidelberg Basin Drilling Project (Gabriel et al. 2008), a detailed sediment succession is presented here based upon deep drillings taken at Heidelberg UniNord and Mannheim Käfertal. Sediment structures, and micromorphological and pollen analyses were conducted and used to reconsider some of the climate transitions within the lower Pleistocene. A new and novel scenario is postulated regarding the preservation of Quaternary sediment packages within the Cenozoic Graben environment of the Heidelberg basin. The palynological evidence comprises the periods of warm climate of the Holsteinian (mainly Abies (fir), some Fagus (beech), Pterocarya & Azolla); the Cromerian (Pinus-Picea-QM (pine-spruce-QM)); the Bavelian (Abies, Tsuga (hemlock fir), QM & phases of increased NAP including Pinus); the Waalian (Abies, Tsuga, QM); and the Tiglian (Fagus & early Pleistocene taxa especially Sciadopytis, downward increasing Tertiary taxa). The sediment package was studied both macroscopically and microscopically. Both techniques provide evidence of fluvial, lacustrine and mass movement sedimentary processes. Some include evidence of periglacial processes (silt droplets within fine grained sands indicative of frozen ground conditions). The periglacial structures are often, not always, accompanied by pollen spectra dominated by pine and NAP. E.g. the Tiglian part of the succession shows periglacial sediment structures at its base and top but not in its middle sections. I.e. it appears not as a series of warm and cold phases but rather as a constant warm period with warm-cold-alternations at its bottom and top. All results illustrate sediment preservation in the Heidelberg basin almost throughout the Quaternary. This may be due to tectonic subsidence, but also to compaction by sediment loading of underlying fine sediments (Oligocene to Quaternary) leading to incomplete but virtually continuous sediment preservation (Tanner et al. 2009).

    The successive projections algorithm (SPA) is widely used to select variables for multiple linear regression (MLR) modeling. However, SPA used only once may not obtain all the useful information of the full spectra, because the number of selected variables cannot exceed the number of calibration samples in the SPA algorithm. Therefore, the SPA-MLR method risks the loss of useful information. To make a full use of the useful information in the spectra, a new method named "consensus SPA-MLR" (C-SPA-MLR) is proposed herein. This method is the combination of consensus strategy and SPA-MLR method. In the C-SPA-MLR method, SPA-MLR is used to construct member models with different subsets of variables, which are selected from the remaining variables iteratively. A consensus prediction is obtained by combining the predictions of the member models. The proposed method is evaluated by analyzing the near infrared (NIR) spectra of corn and diesel. The results of C-SPA-MLR method showed a better prediction performance compared with the SPA-MLR and full-spectra PLS methods. Moreover, these results could serve as a reference for combination the consensus strategy and other variable selection methods when analyzing NIR spectra and other spectroscopic techniques.

    In the past years the Dutch program Reduction Other Greenhouse Gases (ROB) focused on the enhancement, development and implementation of measures aimed at reducing emissions of non-CO2 greenhouse gases. The main focus was directed to agriculture. Cooling and landfills. SenterNovem (currently named NL Agency) offered options for subsidies, knowledge and advice to start working on the reduction of non-CO2 greenhouse gases. A few examples of successful projects financed by ROB subsidy are briefly discussed. [Dutch] Het programma Reductie Overige Broeikasgassen (ROB) richtte zich de afgelopen jaren op het bevorderen, ontwikkelen en toepassen van maatregelen ter vermindering van de uitstoot van niet-CO2 broeikasgassen. De aandacht ging hierbij vooral uit naar de emissies van overige broeikasgassen afkomstig uit de landbouw, koeling en stortplaatsen. SenterNovem (nu het Agentschap NL) bood subsidiemogelijkheden, kennis en advies om met de reductie van niet-CO2 broeikasgassen aan de slag te gaan.

    Spectral analysis technique based on near infrared (NIR) sensor is a powerful tool for complex information processing and high precision recognition, and it has been widely applied to quality analysis and online inspection of agricultural products. This paper proposes a new method to address the instability of small sample sizes in the successive projections algorithm (SPA) as well as the lack of association between selected variables and the analyte. The proposed method is an evaluated bootstrap ensemble SPA method (EBSPA) based on a variable evaluation index (EI) for variable selection, and is applied to the quantitative prediction of alcohol concentrations in liquor using NIR sensor. In the experiment, the proposed EBSPA with three kinds of modeling methods are established to test their performance. In addition, the proposed EBSPA combined with partial least square is compared with other state-of-the-art variable selection methods. The results show that the proposed method can solve the defects of SPA and it has the best generalization performance and stability. Furthermore, the physical meaning of the selected variables from the near infrared sensor data is clear, which can effectively reduce the variables and improve their prediction accuracy.

    1999-01-01

    To estimate the effect of subsonic and supersonic aircraft exhaust on the stratospheric concentration of NO(y), we employ a trajectory model initialized with air parcels based on the standard release scenarios. The supersonic exhaust simulations are in good agreement with 2D and 3D model results and show a perturbation of about 1-2 ppbv of NO(y) in the stratosphere. The subsonic simulations show that subsonic emissions are almost entirely trapped below the 380 K potential temperature surface. Our subsonic results contradict results from most other models, which show exhaust products penetrating above 380 K, as summarized. The disagreement can likely be attributed to an excessive vertical diffusion in most models of the strong vertical gradient in NO(y) that forms at the boundary between the emission zone and the stratosphere above 380 K. Our results suggest that previous assessments of the impact of subsonic exhaust emission on the stratospheric region above 380 K should be considered to be an upper bound.

    Full Text Available In project management context, time management is one of the most important factors affecting project success. This paper proposes a new method to solve research project scheduling problems (RPSP containing Fuzzy Graphical Evaluation and Review Technique (FGERT networks. Through the deliverables of this method, a proper estimation of project completion time (PCT and success probability can be achieved. So algorithms were developed to cover all features of the problem based on three main parameters “duration, occurrence probability, and success probability.” These developed algorithms were known as PR-FGERT (Parallel and Reversible-Fuzzy GERT networks. The main provided framework includes simplifying the network of project and taking regular steps to determine PCT and success probability. Simplifications include (1 equivalent making of parallel and series branches in fuzzy network considering the concepts of probabilistic nodes, (2 equivalent making of delay or reversible-to-itself branches and impact of changing the parameters of time and probability based on removing related branches, (3 equivalent making of simple and complex loops, and (4 an algorithm that was provided to resolve no-loop fuzzy network, after equivalent making. Finally, the performance of models was compared with existing methods. The results showed proper and real performance of models in comparison with existing methods.

  16. MAXIMUM PRINCIPLE FOR SUBSONIC FLOW WITH VARIABLE ENTROPY

    Full Text Available Maximum principle for subsonic flow is fair for stationary irrotational subsonic gas flows. According to this prin- ciple, if the value of the velocity is not constant everywhere, then its maximum is achieved on the boundary and only on the boundary of the considered domain. This property is used when designing form of an aircraft with a maximum critical val- ue of the Mach number: it is believed that if the local Mach number is less than unit in the incoming flow and on the body surface, then the Mach number is less then unit in all points of flow. The known proof of maximum principle for subsonic flow is based on the assumption that in the whole considered area of the flow the pressure is a function of density. For the ideal and perfect gas (the role of diffusion is negligible, and the Mendeleev-Clapeyron law is fulfilled, the pressure is a function of density if entropy is constant in the entire considered area of the flow. Shows an example of a stationary sub- sonic irrotational flow, in which the entropy has different values on different stream lines, and the pressure is not a function of density. The application of the maximum principle for subsonic flow with respect to such a flow would be unreasonable. This example shows the relevance of the question about the place of the points of maximum value of the velocity, if the entropy is not a constant. To clarify the regularities of the location of these points, was performed the analysis of the com- plete Euler equations (without any simplifying assumptions in 3-D case. The new proof of the maximum principle for sub- sonic flow was proposed. This proof does not rely on the assumption that the pressure is a function of density. Thus, it is shown that the maximum principle for subsonic flow is true for stationary subsonic irrotational flows of ideal perfect gas with variable entropy.

    ENGLISH ABSTRACT: Transnet Freight Rail in South Africa has faced projects delays in its multi-project environment. This study takes South Africa as representative of developing countries, and develops the Critical Success Factors (CSFs model for multiple projects success, with the goal of expanding the conventional model by adding the demographic characteristics of the business units involved in the multiple projects. The empirical results showing the greatest number of success factors are people-related, with the focus on team selection and team commitment. Two demographic characteristics are of importance when managing multiple projects: the size of the business unit, and the employees’ project experience.

    The first experiments on the subsonic laminar microjets escaping from the nozzles of rectangular shape are carried out. The nozzle size is 83.3x3823 microns. Reynolds number calculated by the nozzle height and the average flow velocity at the nozzle exit ranged from 58 to 154. The working gas was air at room temperature. The velocity decay and velocity fluctuations along the center line of the jet are determined. The fundamental difference between the laminar microjets characteristics and subsonic turbulent jets of macro size is shown. Based on measurements of velocity fluctuations it is shown the presence of laminar-turbulent transition in microjets and its location is determined.

    2017-12-01

    Full Text Available We investigate students’ sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues in each project, and constructing chronological descriptions of those events. Cross-case analysis focused on identifying emergent themes with respect to five dimensions of project ownership: student agency, instructor mentorship, peer collaboration, interest and value, and affective responses. Our within- and cross-case analyses yielded three major findings. First, coupling division of labor with collective brainstorming can help balance student agency, instructor mentorship, and peer collaboration. Second, students’ interest in the project and perceptions of its value can increase over time; initial student interest in the project topic is not a necessary condition for student ownership of the project. Third, student ownership is characterized by a wide range of emotions that fluctuate as students alternate between extended periods of struggle and moments of success while working on their projects. These findings not only extend the literature on student ownership into a new educational domain—namely, upper-division physics labs—they also have concrete implications for the design of experimental physics projects in courses for which student ownership is a desired learning outcome. We describe the course and projects in sufficient detail that others can adapt our results to their particular contexts.

    Large wood (LW) jams have long been utilized as a stream restoration strategy to create fish habitat, with a strong focus on Coho salmon in the Pacific Northwest. These projects continue to be implemented despite limited understanding of their success in streams of different size. In this study, we assessed the changes triggered by LW introductions in 10 alluvial plane bed reaches with varying drainage areas (3.9-22 km²) and bankfull widths (6.4-14.7 m) in one Oregon Coast Range basin. In this basin, LW was added in an effort to improve winter rearing habitat for Coho salmon. We used detailed topographic mapping (0.5 m² resolution) to describe the local stream and floodplain geometry. Pebble counts were used to monitor changes in average substrate size after the LW addition. Field surveys were conducted immediately after the LW were installed, in the summer of 2016, and one year after installation, in the summer of 2017. We used geomorphic change detection analysis to quantify the amount of scour and deposition at each site along with changes in average bankfull width. Then we determined the relative amount of change among all sites to identify which size stream changed the most. We also modeled fluctuations in water surface elevation at each site, correlating frequency and inundation of the LW with geomorphic changes detected from the topographic surveys. Preliminary results show an increase in channel width and floodplain connectivity at all sites, indicating an increase in off-channel habitat for juvenile Coho salmon. Bankfull widths increased up to 75% in small sites and up to 25% in large sites. Median grain size became coarser in large streams (increased up to 20%), while we saw a similar amount of fining at smaller sites. The overall increase in channel width is compensated by an overall decrease in bed elevation at both large and small sites, suggesting the maintenance of overall geomorphic equilibrium. Further work will include quantifying these

    This paper addresses the factors involved in effectively implementing a world-class program/project management information system funded by multiple nations. Along with many other benefits, investing in and utilizing such systems improves delivery and drive accountability for major expenditures. However, there are an equally large number of impediments to developing and using such systems. To be successful, the process requires a dynamic combining of elements and strategic sequencing of initiatives. While program/project-management systems involve information technologies, software and hardware, they represent only one element of the overall system.. Technology, process, people and knowledge must all be integrated and working in concert with one another to assure a fully capable system. Major system implementations occur infrequently, and frequently miss established targets in relatively small organizations (with the risk increasing with greater complexity). The European Bank of Reconstruction (EBRD) is midway through just such an implementation. The EBRD is using funds from numerous donor countries to sponsor development of an overarching program management system. The system will provide the Russian Federation with the tools to effectively manage prioritizing, planning, and physically decommissioning assets i n northwest Russia to mitigate risks associated the Soviet era nuclear submarine program. Project-management delivery using world-class techniques supported by aligned systems has been proven to increase the probability of delivering on-time and on-budget, assuring those funding such programs optimum value for money. However, systems deployed to manage multi-laterally funded projects must be developed with appropriate levels of consideration given to unique aspects such as: accommodation of existing project management methods, consideration for differences is management structures and organizational behaviors, incorporation of unique strengths, and subtle

  8. Three dimensional steady subsonic Euler flows in bounded nozzles

    Science.gov (United States)

    Chen, Chao; Xie, Chunjing

    The existence and uniqueness of three dimensional steady subsonic Euler flows in rectangular nozzles were obtained when prescribing normal component of momentum at both the entrance and exit. If, in addition, the normal component of the voriticity and the variation of Bernoulli's function at the entrance are both zero, then there exists a unique subsonic potential flow when the magnitude of the normal component of the momentum is less than a critical number. As the magnitude of the normal component of the momentum approaches the critical number, the associated flows converge to a subsonic-sonic flow. Furthermore, when the normal component of vorticity and the variation of Bernoulli function are both small, the existence and uniqueness of subsonic Euler flows with non-zero vorticity are established. The proof of these results is based on a new formulation for the Euler system, a priori estimate for nonlinear elliptic equations with nonlinear boundary conditions, detailed study for a linear div-curl system, and delicate estimate for the transport equations.

    Increasing efforts are being made globally on capacity building. North-south research partnerships have contributed significantly to enhancing the research capacity in low- and middle-income countries (LMICs) over the past few decades; however, a lack of skilled researchers to inform health policy development persists, particularly in LMICs. The EU FP7 funded African/Asian Regional Capacity Development (ARCADE) projects were multi-partner consortia aimed to develop a new generation of highly trained researchers from universities across the globe, focusing on global health-related subjects: health systems and services research and research on social determinants of health. This article aims to outline the successes, challenges and lessons learned from the life course of the projects, focusing on the key outputs and experiences of developing and implementing these two projects together with sub-Saharan African, Asian and European institution partners. Sixteen participants from 12 partner institutions were interviewed. The data were analysed using thematic content analysis, which resulted in four themes and three sub-categories. These data were complemented by a review of project reports. The results indicated that the ARCADE projects have been successful in developing and delivering courses, and have reached over 920 postgraduate students. Some partners thought the north-south and south-south partnerships that evolved during the project were the main achievement. However, others found there to be a 'north-south divide' in certain aspects. Challenges included technical constraints and quality assurance. Additionally, adapting new teaching and learning methods into current university systems was challenging, combined with not being able to award students with credits for their degrees. The ARCADE projects were introduced as an innovative and ambitious project idea, although not designed appropriately for all partner institutions. Some challenges were underestimated

    The potential impacts of citizen science initiatives are increasing across the globe, albeit in an imbalanced manner. In general, there is a strong element of trial and error in most projects, and the comparison of best practices and project structure between different initiatives remains difficult. In Brazil, the participation of volunteers in environmental research is limited. Identifying the factors related to citizen science projects' success and longevity within a global perspective can contribute for consolidating such practices in the country. In this study, we explore past and present projects, including a case study in Brazil, to identify the spatial and temporal trends of citizen science programs as well as their best practices and challenges. We performed a bibliographic search using Google Scholar and considered results from 2005-2014. Although these results are subjective due to the Google Scholar's algorithm and ranking criteria, we highlighted factors to compare projects across geographical and disciplinary areas and identified key matches between project proponents and participants, project goals and local priorities, participant profiles and engagement, scientific methods and funding. This approach is a useful starting point for future citizen science projects, allowing for a systematic analysis of potential inconsistencies and shortcomings in this emerging field.

    To describe the evolution and results of health projects run in hospitals and managed by Nursing Coordinators. A convenience sample of 13 north Italian hospital, and a sample of 56 Nursing Coordinators with a permanent position from at least 1 year, was contacted. The following information was collected with a structured interview: projects run in 2009, topic, if bottom up or top down, number of staff involved and state (ended, still running, stopped). In 2009 Nursing Coordinators started 114 projects (mean 1.8±1.2 each): 94 (82.5%) were improvement projects, 17 (14.9%) accreditation, and 3 (2.6%) research. The projects involved 2.732 staff members (73.7%; average commitment 84 hours); 55 (48.2%) projects were still running, 52 (45.6%) completed, for 5 (4.4%) there was no assessment and 2 (1.8%) had been stopped. Nurses are regularly involved in several projects. A systematic monitoring of the results obtained and stabilization strategies are scarce. Due to the large number of resources invested, a correct management and the choice of areas relevant for patients' problems and needs are pivotal.

  14. Public project success as seen in a broad perspective.: Lessons from a meta-evaluation of 20 infrastructure projects in Norway.

    2018-08-01

    Infrastructure projects in developed countries are rarely evaluated ex-post. Despite their number and scope, our knowledge about their various impacts is surprisingly limited. The paper argues that such projects must be assessed in a broad perspective that includes both operational, tactical and strategic aspects, and unintended as well as intended effects. A generic six-criteria evaluation framework is suggested, inspired by a framework frequently used to evaluate development assistance projects. It is tested on 20 Norwegian projects from various sectors (transport, defence, ICT, buildings). The results indicate that the majority of projects were successful, especially in operational terms, possibly because they underwent external quality assurance up-front. It is argued that applying this type of standardized framework provides a good basis for comparison and learning across sectors. It is suggested that evaluations should be conducted with the aim of promoting accountability, building knowledge about infrastructure projects, and continuously improve the tools, methods and governance arrangements used in the front-end of project development.

    2002-01-01

    Since 1998, the Department of Energy's (DOE) Office of Environmental Management has funded the Accelerated Site Technology Deployment (ASTD) Program to expedite deployment of alternative technologies that can save time and money for the environmental cleanup at DOE sites across the nation. The ASTD program has accelerated more than one hundred deployments of new technologies under 76 projects that focus on a broad spectrum of EM problems. More than 25 environmental restoration projects have been initiated to solve the following types of problems: characterization of the subsurface using chemical, radiological, geophysical, and statistical methods; treatment of groundwater contaminated with DNAPLs, metals, or radionuclides; and other projects such as landfill covers, purge water management systems, and treatment of explosives-contaminated soils. One of the major goals of the ASTD Program is to deploy a new technology or process at multiple DOE sites. ASTD projects are encouraged to identify subsequent deployments at other sites. Some of the projects that have successfully deployed technologies at multiple sites focusing on cleanup of contaminated groundwater include: Permeable Reactive Barriers (Monticello, Rocky Flats, and Kansas City), treating uranium and organics in groundwater; and Dynamic Underground Stripping (Portsmouth, and Savannah River), thermally treating DNAPL source zones. Each year more and more new technologies and approaches are being used at DOE sites due to the ASTD program. DOE sites are sharing their successes and communicating lessons learned so that the new technologies can replace the baseline or standard approaches at DOE sites, thus expediting cleanup and saving money

    2013-01-01

    A conceptual design and cost estimate for a subsonic flight research vehicle designed to support NASA's Environmentally Responsible Aviation (ERA) project goals is presented. To investigate the technical and economic feasibility of modifying an existing aircraft, a highly modified Boeing 717 was developed for maturation of technologies supporting the three ERA project goals of reduced fuel burn, noise, and emissions. This modified 717 utilizes midfuselage mounted modern high bypass ratio engines in conjunction with engine exhaust shielding structures to provide a low noise testbed. The testbed also integrates a natural laminar flow wing section and active flow control for the vertical tail. An eight year program plan was created to incrementally modify and test the vehicle, enabling the suite of technology benefits to be isolated and quantified. Based on the conceptual design and programmatic plan for this testbed vehicle, a full cost estimate of $526M was developed, representing then-year dollars at a 50% confidence level.

    Full Text Available Nowadays, project-based organizations need to utilize intellectual capital and knowledge to become leader in their business activities. The new approach to use knowledge based skills from one side and development of the new complicated products from the other side have increased the need for designing a lessons learned model. The purpose of this paper is to design a lessons learned model to improve the success of new product development for project oriented organizations. The study designs a questionnaire in Likert scale and distributes it among 56 experts who were well informed about various techniques of new product development and lessons learned. Cronbach alphas for all components of the survey were well above the desirable level. The results of the survey have indicated that there were positive and meaningful relationships between lessons learned components and the success of the new product development.

    The recently completed project to repair the ChNPP Unit 3/4 ventilation stack is the first international project providing a direct physical improvement and safety upgrade at the Shelter (Ukrytie) facility. The 1986 explosion at Chernobyl NPP Unit 4 severely damaged the ventilation stack framework of bracing and its foundation. At one node, where six elements of the framework joined together, one element was completely missing one element was torn from the node and left hanging from its other end, and one element was badly bent and dented. Foundation supports were knocked measurably off plumb. Repair of the ChNPP ventilation stack is the first international project providing direct physical improvement and safety upgrade at the Shelter facility. The repairs have restored the stack to full design strength, from an emergency condition with a high probability of collapse

    The significance of public awareness (PA) programme at Kudankulam Nuclear Power Project (KKNPP) was well recognised since the inception stage itself and several PA programme were organised around Kudankulam through different means of communication. In its chequered progress, the Kudankulam project has seen ups and downs from the initial stage and in the year 2011, the site witnessed an impasse due to public interest and concerns on nuclear projects. Subsequently PA programmes were taken up on a war footing with persistent efforts, public fear on nuclear energy and safety concerns were allayed among local public in the villages in and around Kudankulam and also far and wide in Tamil Nadu and Kerala. This paper discusses the various measures initiated to disseminate the right information and educating public on nuclear energy as a clean energy option for environmental safety. In addition, it is a requirement of the country in the face of impending climate change concerns and warming of the earth's surface

    The Watershed Dynamics project is a partnership between Northwestern University, the Consortium of Universities for the Advancement of Hydrologic Science (CUAHSI), and the GLOBE Program (Global Learning and Observations to Benefit the Environment). The goal of the project is to develop inquiry-based educational materials that use authentic scientific data and analysis techniques to teach students about the watershed. The relationship between Northwestern, CUAHSI, and GLOBE allows each partner to contribute to the development of the project in the area of their expertise. Science researchers from CUAHSI share science content knowledge and data access through the development of their Hydrologic Information System (HIS). Curriculum developers at Northwestern write inquiry-based curriculum using GIS technology to access and analyze live data. The GLOBE Program is a worldwide hands-on, primary and secondary school-based science education program that provides teacher training opportunities to a network of teachers around the world. This partnership allows each partner to bring their area of expertise to the project and make the best use of one another's resources. The Watershed Dynamics project can serve as a model for future partnerships between the science and education communities. The Office of Science, Technology, Engineering, and Math Education Partnerships (OSEP) at Northwestern is a service organization that supports Northwestern researchers in developing proposals and implementing research projects that incorporate K-12 educational components, particularly in the fields of science, technology, engineering and mathematics (STEM). OSEP assists faculty with the development of sound plans for education and outreach that reflect current research on learning and educational reform and provides expertise in STEM education materials development, learning technologies, and professional development for K-12 teachers and facilitators in informal education institutions

    The establishment of the Norwegian Fractionation Project (Project) was of major importance in preserving national self-sufficiency when plasma, cryoprecipitate and small batch factor IX-concentrates were replaced by virus inactivated products in the last part of the 1980s. Fractionation was performed abroad by contract with Octapharma after tenders on the European market. All Norwegian blood banks (>50) participated in the Project. Total yearly production was 50-60 tons of mainly recovered plasma. From 1993 solvent detergent (SD) treated plasma has replaced other plasma for transfusion. The blood banks paid for the fractionation and/or viral inactivation process, while the plasma remained the property of the blood banks and the final products were returned to the blood banks. The Project sold surplus products to other Norwegian blood banks and the majority of the coagulation factor concentrates to The Institute of Haemophilia and Rikshospitalet University Hospital. Both plasma and blood bank quality was improved by the Project. Clinical experience with the products has been satisfactory and self-sufficiency has been achieved for all major plasma proteins and SD plasma, but a surplus exceeding 3 years consumption of albumin has accumulated due to decreasing clinical use.The Project has secured high yields of the fractionated products and the net income from the produced products is NOK 1115 (140 Euros or US dollars) per litre plasma. An increasing surplus of albumin and the possibility of significant sales abroad of currently not fractionated IVIgG, could lead to a reorganisation of the Project from that of a co-ordinator to a national plasma handling unit. This unit could buy the plasma from the blood banks and have the plasma fractionated by contract after tender, before selling the products back for cost recovery. The small blood banks could produce plasma for products for the Norwegian market, while surplus products from the larger blood banks which are

    With recent reports of public enquiries into failure to care, universities are under pressure to ensure that candidates selected for undergraduate nursing programmes demonstrate academic potential as well as characteristics and values such as compassion, empathy and integrity. The Multiple Mini Interview (MMI) was used in one university as a way of ensuring that candidates had the appropriate numeracy and literacy skills as well as a range of communication, empathy, decision-making and problem-solving skills as well as ethical insights and integrity, initiative and team-work. To ascertain whether there is evidence of bias in MMIs (gender, age, nationality and location of secondary education) and to determine the extent to which the MMI is predictive of academic success in nursing. A longitudinal retrospective analysis of student demographics, MMI data and the assessment marks for years 1, 2 and 3. One university in southwest London. One cohort of students who commenced their programme in September 2011, including students in all four fields of nursing (adult, child, mental health and learning disability). Inferential statistics and a Bayesian Multilevel Model. MMI in conjunction with MMI numeracy test and MMI literacy test shows little or no bias in terms of ages, gender, nationality or location of secondary school education. Although MMI in conjunction with numeracy and literacy testing is predictive of academic success, it is only weakly predictive. The MMI used in conjunction with literacy and numeracy testing appears to be a successful technique for selecting candidates for nursing. However, other selection methods such as psychological profiling or testing of emotional intelligence may add to the extent to which selection methods are predictive of academic success on nursing.

    Propagation of heat fronts relevant to astrophysical plasmas is challenging in the supersonic regime. Plasma Te changes affect opacity and equation of state without hydrodynamic change. In the subsonic phase density perturbations form at material interfaces as the plasma responds to radiation pressure of the front. Recent experiments at OMEGA studied this transition in aerogel foams driven by a hohlraum. In COAX, two orthogonal backlighters drive x-ray radiography and K-shell absorption spectroscopy to diagnose the subsonic shape of the front and supersonic Te profiles. Past experiments used absorption spectroscopy in chlorinated foams to measure the heat front; however, Cl dopant is not suitable for higher material temperatures at NIF. COAX has developed use of Sc and Ti dopants to diagnose Te between 60-100eV and 100-180eV. Analysis with PrismSPECT using OPLIB tabular opacity data will evaluate the platform's ability to advance radiation transport in this regime.

    The opportunity exists for academia and the nursing executive community to collaboratively create cultures of excellence. One university formed relationships of collaborative synergy with nurse executives to provide practicum experiences of value for both the graduate nursing administration students and the health care facilities. The strategic preceptor partnerships offer graduate students the invaluable opportunity to experience the in-depth, real world perspective of nursing administration resulting in the enrichment of their academic scholarship. A final practicum work project is designed collaboratively with the preceptor and completed by the end of the second practicum semester. The resulting practicum project is an example of a mutually rewarding experience for the graduate nursing administration student and the preceptor. The collaborative synergistic model is a win-win situation for the university and the health care facility.

North–south research partnerships have contributed significantly to enhancing the research capacity in low- and middle-income countries (LMICs over the past few decades; however, a lack of skilled researchers to inform health policy development persists, particularly in LMICs. The EU FP7 funded African/Asian Regional Capacity Development (ARCADE projects were multi-partner consortia aimed to develop a new generation of highly trained researchers from universities across the globe, focusing on global health-related subjects: health systems and services research and research on social determinants of health. This article aims to outline the successes, challenges and lessons learned from the life course of the projects, focusing on the key outputs and experiences of developing and implementing these two projects together with sub-Saharan African, Asian and European institution partners. Design: Sixteen participants from 12 partner institutions were interviewed. The data were analysed using thematic content analysis, which resulted in four themes and three sub-categories. These data were complemented by a review of project reports. Results: The results indicated that the ARCADE projects have been successful in developing and delivering courses, and have reached over 920 postgraduate students. Some partners thought the north–south and south–south partnerships that evolved during the project were the main achievement. However, others found there to be a ‘north–south divide’ in certain aspects. Challenges included technical constraints and quality assurance. Additionally, adapting new teaching and learning methods into current university systems was challenging, combined with not being able to award students with credits for their degrees. Conclusion: The ARCADE projects were introduced as an innovative and ambitious project idea, although not designed

Image: courtesy of Don Mitchell, FNAL. The 11-Tesla dipole project originated from a proposal made by High Luminosity LHC project coordinator, Lucio Rossi, in September 2010. To cope with the increasing amount of debris hitting the magnets when increasing the number of collisions produced by the LHC, he suggested replacing a few 8-Tesla dipole magnets in the LHC tunnel with shorter, stronger 11-Tesla magnets in order to create enough space to install additional collimators. The only way to achieve this goal is to use advanced niobium-tin technology. Rossi’s proposal aligned well with the goals of Fermilab’s High-Field Magnet R&D programme, which aims t...

If, in addition, the normal component of the voriticity and the variation of Bernoulli's function at the exit are both zero, then there exists a unique subsonic potential flow when the magnitude of the normal component of the momentum is less than a critical number. As the magnitude of the normal compon...

    Albeit the understanding that construction waste is caused by activities ranging from all stages of project delivery process, research efforts have been concentrated on design and construction stages, while the possibility of reducing waste through materials procurement process is widely neglected. This study aims at exploring and confirming strategies for achieving waste-efficient materials procurement in construction activities. The study employs sequential exploratory mixed method approach as its methodological framework, using focus group discussion, statistical analysis and structural equation modelling. The study suggests that for materials procurement to enhance waste minimisation in construction projects, the procurement process would be characterised by four features. These include suppliers' commitment to low waste measures, low waste purchase management, effective materials delivery management and waste-efficient Bill of Quantity, all of which have significant impacts on waste minimisation. This implies that commitment of materials suppliers to such measures as take back scheme and flexibility in supplying small materials quantity, among others, are expected of materials procurement. While low waste purchase management stipulates the need for such measures as reduced packaging and consideration of pre-assembled/pre-cut materials, efficient delivery management entails effective delivery and storage system as well as adequate protection of materials during the delivery process, among others. Waste-efficient specification and bill of quantity, on the other hand, requires accurate materials take-off and ordering of materials based on accurately prepared design documents and bill of quantity. Findings of this study could assist in understanding a set of measures that should be taken during materials procurement process, thereby corroborating waste management practices at other stages of project delivery process.

    The German "Dr med" plays a specific role in doctoral thesis settings since students may start the underlying doctoral project during their studies at medical school. If a Medical Faculty principally encourages this approach, then it should support the students in performing the respective projects as efficiently as possible. Consequently, it must be ensured that students are able to implement and complete a doctoral project in parallel to their studies. As a characteristic efficiency feature of these "Dr med" initiatives, the proportion of doctoral projects successfully completed shortly after graduating from medical school is proposed and illustrated. The proposed characteristic can be estimated by the time period between the state examination (date of completion of the qualifying medical examination) and the doctoral examination. Completion of the doctoral project "during their medical studies" was then characterised by a doctoral examination no later than 12 months after the qualifying medical state examination. To illustrate the estimation and interpretation of this characteristic, it was retrospectively estimated on the basis of the full sample of all doctorates successfully completed between July 2009 and June 2012 at the Department of Human Medicine at the Faculty of Health of the University of Witten/Herdecke. During the period of investigation defined, a total number of 56 doctoral examinations were documented, 30 % of which were completed within 12 months after the qualifying medical state examination (95% confidence interval 19 to 44 %). The median duration between state and doctoral examination was 27 months. The proportion of doctoral projects completed parallel to the medical studies increased during the investigation period from 14 % in the first year (July 2009 till June 2010) to 40 % in the third year (July 2011 till June 2012). Only about a third of all "Dr med" projects at the Witten/Herdecke Faculty of Health were completed during or close to

    Westinghouse Electric Company, LLC (WEC) has been providing advanced Instrumentation and Control (I and C) technology for the C E System 80, Korean Standard Nuclear Power Plant (KSNP), since the early 1990's. I and C equipment and technical support has been provided for a progression of these plants including Yonggwang Units 3,4,5,6, Ulchin Units 3,4,5,6, Shin Kori Units 1 and 2, Shin Wolsong Units 1 and 2, and most recently for Shin Kori Units 3 and 4. These I and C programs have been highly successful and have helped to contribute to the outstanding plant availability for the commissioned units at Yonggwang 3,4,5, and 6 and Ulchin 3,4,5, and 6; which are currently providing power on the grid. WEC has also recently delivered I and C equipment for Shin Kori Units 1 and 2 and Shin Wolsong Units 1 and 2 and is supporting the installation and startup of the equipment. In addition, WEC is in the initial design stages for providing an integrated protection system that will be deployed at Shin Kori Units 3 and 4 which are the first units to implement the APR1400; an advanced reactor of indigenous Korean design, which is based on the previous generation Optimized Power Reactor OPR1000. The success of the I and C programs has been the result of careful consideration of the appropriate technology to employ, applying comprehensive quality assurance measures, providing appropriate technical support and consultation services, implementation of a program of continued I and C logistic support, maintaining a professional and experienced I and C work force, and maintaining a strong and mutually supportive partnership with the Korea Power Engineering Company (KOPEC) and with Korea Hydro and Nuclear Power (KHNP). WEC takes great pride in its on going I and C partnership with Korea, which has included not only providing equipment and technical support services, but also completion of a comprehensive Technology Transfer program. This program was implemented to promote local 'elf

    The New York University (NYU) Health Sciences Library used a new method to arrange in-depth discussions with basic science researchers. The objective was to identify collaborators for a new National Library of Medicine administrative supplement. The research took place at the NYU Health Sciences Library. Using the National Institutes of Health (NIH) RePORTER, forty-four researchers were identified and later contacted through individualized emails. Nine researchers responded to the email followed by six in-person or phone discussions. At the conclusion of this process, two researchers submitted applications for supplemental funding, and both of these applications were successful. This method confirmed these users could benefit from the skills and knowledge of health sciences librarians, but they are largely unaware of this.

    This paper describes simultaneous, synchronized, high-frequency measurements of both unsteady flow in the wake of a tension-cone decelerator in subsonic flow (by PIV) and the unsteady shape of the decelerator (by photogrammetry). The purpose of these measurements was to develop the test techniques necessary to validate numerical methods for computing fluid-structure interactions of flexible decelerators. A critical need for this effort is to map fabric surfaces that have buckled or wrinkled so that code developers can accurately represent them. This paper describes a new photogrammetric technique that performs this measurement. The work was done in support of the Entry, Descent, and Landing discipline within the Supersonics Project of NASA s Fundamental Aeronautics Program.

    CH2M Hill Plateau Remediation Company (CHPRC) recently completed construction and start-up of the $25 million 100-HX Groundwater Pump and Treat Project for the Department of Energy (DOE) at its Hanford Reservation site in Washington State. From the onset, the 100-HX Project Leadership Team was able to successfully blend the science and technology of a state-of-the-art groundwater pump and treat system with the principles, tools, and techniques of traditional industrial-type construction and project management. From the 1940's through most of the 1980's, the United States used the Hanford Site to produce nuclear material for national defense at reactor sites located along the Columbia River. While the reactors were operational, large volumes of river water were treated with sodium dichromate (to inhibit corrosion of the reactor piping) and used as a coolant for the reactors. After a single pass through the reactor and before being discharged back to the river, the coolant water was sent to unlined retention basins to cool and to allow the short-lived radioactive contaminants to decay. As a result of these operations, hexavalent chromium was introduced to the vadose zone, and ultimately into the groundwater aquifer and the adjacent Columbia River. In addition, numerous leaks and spills of concentrated sodium dichromate stock solution over the lifetime of reactor operations led to higher concentrations of chromate in the vadose zone and groundwater in localized areas. As a result, the 100 Area was included in the National Priorities List sites under the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA). The mission of the 100-HX Project is to significantly reduce the concentration of hexavalent chromium in the groundwater by treating up to 3.8 billion gallons (14,300 mega-liters) of contaminated water over its first nine years of operations. In order to accomplish this mission, groundwater scientists and geologists using

    Originally designed in Quebec, the MOI project was a collaboration between two professors of social work from Quebec and two members of the Peruvian NGO called SUR in Villa de Salvador, one of poorest slum areas on the outskirts of Lima. The approach is founded on the notion that the body is the primary instrument through which a person can interact with the world around him or her, and that the physical and mental health of an individual exists within the context of healthy conditions of life that must include at least a basic social and health infrastructure as well as healthy hygiene practices on the part of individuals, families and the local community. Preschool children (ages 4-6), study a different part of the body and its proper care each week through classroom observation games. Parents' help is requested to modify unhealthy conditions, at the same time to enrich the children's experience and to mobilize the community to improve health conditions. During the 1991 cholera epidemic, not a single case was counted in the experimental district, despite its clearly socio-economically impoverished status, and despite the fact that the Ministry of Health recorded 86,650 cases in the Lima-Callao district, accounting for about 40% of the total number of cases in the Peru. The prior work made it easier to explain how cholera is spread and what special new measures needed to be taken in addition to the hygiene habits already taught.(ABSTRACT TRUNCATED AT 250 WORDS)

    In 1984, the U.S. Congress issued the Carl D. Perkins Act, which charges vocational educators to increase their focus on two broad themes: (a) the elimination of sexual bias and sexual stereotyping in vocational education and (b) the provision of marketable skills to the economically deprived of the nation's work force. In response to this charter, an industry/education partnership was established among the Illinois State Board of Education, Norther Illinois University, and the Westinbghouse Nuclear Training Center. In essence, these partners established Project WANT - Women's Access to Nuclear Technology - with two premier goals: (a) to increase women's awareness regarding nuclear career opportunities and (b) to train and place women in technical professions within the nuclear industry. Feedback from the U.S. Department of Energy (DOE), the Atomic Industrial Forum, and the Bureau of Labor Statistics identifies that <2% of all technical positions within the nuclear power industry are held by women. Hence, one may conclude that there is a definite need to promote sexual equity in the nuclear industry and that Illinois represents a unique environment of opportunity to accomplish this

    environment possible in whatever form the focus group takes place. Suggestions for future research include recruiting participants from online classes and attempting to engage more disenfranchised students in other studies. Similar to new types of focus group methods due to technological advances, academic interventions for students facing failing grades are also increasing due to the internet and new methods of service delivery. The contextual aspect of this research involved asking students to participate in an initial focus group session, four weeks of email updates, and a final focus group session in which students participated in the same group as the initial session. The purpose of the focus groups was to evaluate whether or not the universities' attempts to help students succeed in a course known in the past for high failure rates through a program known as the Early Alert Project was succeeding. Interview data were analyzed using thematic coding to evaluate available support services using a comprehensive implementation evaluation model which included effort, monitoring, process, components; and treatment specification. The primary findings were although students believed the university was trying to help them succeed, Early Alert Project efforts were adversely received. In addition, participants felt that although there were enough support services to help them succeed in the course, the components of the support system were confusing and not organized in any systematic manner. Suggestions for further research included researching delivery of this type of communication that might be more amenable to the students who received it and applying this research to other courses to examine whether the same results occur. Finally, implications of the use of traditional methods and academic support services are discussed in addition to the effect of the research itself upon its participants.

  9. Looking back on a successful project. The Restoration of the Royal Palace in Amsterdam

    Full Text Available After 1968, few changes were made to the Royal Palace in Amsterdam and eventually the palace was no longer functionally and technically up-to-date. Initially, the most recent restoration was only aimed at remedying that situation. Also, the project was split up and priority was given to fixing up the interior. Gradually, the actual restoration gained prominence. In 2007 it was decided to also restore the 1808 furniture. Until 2006, the government architect had hardly been involved in the restoration of the interior. This architect, Krijn van den Ende, was advised by various committees. Prior restorations (1929-1939 and 1960-1968 had restored the palace to its 17th-century state as best as possible. The most recent restoration respected this, while at the same time it aimed at connecting the 17th century character of the building to the unique collection of Empire furniture. This furniture was restored, as were the chandeliers and candelabras. All the ceilings on the first floor were studied and treated and the paintings between the beams were meticulously restored. A very important aspect was the restoration of the so-called ‘Bataven’ series in the galleries. Much of the work concerned making the building conform to contemporary standards. Once again the palace is now a suitable venue for official occasions. The inevitable addition of a lift did however cause quite a stir. Accessibility was improved and more representative rooms are now open to the public than before. The government architect was involved already in the preparatory stages of the second part of the restoration, which concerned the façades and the roofs. In executing the actual work a support committee provided advice and direction on his behalf. Although the sandstone is generally of a high quality, before 1968 a limited number of deteriorating blocks had been replaced. This time too, a number of blocks needed attention. The heavy scaffolding that needed to be installed for

    Mauritania, a country of 3.4 million people, did not have any radiotherapy facility until 2009. As is usually the case in countries without radiotherapy services, cancer patients with a need for this treatment travelled to neighbouring countries (Morocco or Tunisia) or to Europe to receive it, or switched to alternative forms of care. Cancer is a rising cause of death in Mauritania. According to WHO estimates, about 2200 people died of cancer in 2011, of whom 1400 were aged below 70 years of age. The number of patients sent abroad for treatment by the National Health Insurance Fund rose to 500 patients in 2007, causing a significant drain on the State budget. Cancer was the main cause of health related travel abroad. The average cost of such travel was two million ouguiya per patient (US $8000). Through a technical cooperation project initiated in 2009 between the Mauritanian Government and the IAEA, the latter assisted the country with the establishment and operation of its first radiotherapy facility. The National Oncology Centre, including a radiotherapy department, was built in Nouakchott in 2010 and began operation in early 2011 with a limited staff, all hired from abroad. Its equipment includes a modern medical linac with a multileaf collimator and portal imaging, a CT simulator, a 3-D CRT TPS and a remote afterloading HDR brachytherapy system. The centre was planned with an additional bunker, where a second accelerator can be installed in the future. Except for the training of the Department Head, the entire professional team has been trained through the IAEA’s technical cooperation fellowship programme. The centre treated a total of 250 patients in 2012 and treated 176 in the first half of 2013. Most patients undergo simulation and computerized radiotherapy treatment planning. The centre ensures the sustainability of the equipment through full maintenance contracts for the major radiation equipment and source replacements for the HDR brachytherapy unit.

  11. Numerical Calculation of Interaction Between Plane Jet and Subsonic Flow

    Full Text Available The paper makes numerical calculation of interaction between plane jet and subsonic flow. Its aim is to determine the jet trajectory, velocity profiles, distribution of pressure coefficient on the plate surface at different jet angles, namely ωj=45°; 90°; 105° and at low blowing strengths ( ≤1.5 as well as a to make comparison with the experimental data of other authors.To simulate a two-dimensional jet in the subsonic flow the software package “CAD SolidWorks Flow Simulation” has been used. Initially, the test task was solved with its calculation results compared with experimental ones [6.8] in order to improve the convergence; the size of the computational domain and a computational grid within the k-ε turbulence model were selected. As a result of the calculation, were identified and analysed the pressure values, jet trajectories, and velocity profiles. In the graphs the solid lines show calculation results, and dots represent experimental data.From the calculation results it is seen that, with increasing intensity of the reduced mass flow ¯q in the above range, the change of the jet pressure coefficient p¯ distribution behind a slotted nozzle is almost linear and significant. Before the nozzle, with increasing ¯q the pressure coefficient increases slightly.Analysis of results has shown that blowing of jets with ωj>90ω, provides a greater perturbation of the subsonic flow. Thus, the jet penetrates into the flow deeper, forms a dead region of the greater length, and more significantly redistributes the pressure coefficient on the surface of the plate.The calculation results are in good compliance with the experimental data both for the jet axis and for the pressure coefficient distribution on the plate surface. The research results can be used in the designing the jet control of aircrafts.

Aircraft capable of carrying 130 passengers 2,780 km (1500 n.mi.); 200 passengers 5,560 km (3000 n.mi.); and 400 passengers on a 9,265 km (5000 n.mi.) radius mission, were designed parametrically. Both liquid hydrogen and conventionally fueled versions were generated for each payload/range in order that comparisons could be made. Aircraft in each mission category were compared on the basis of weight, size, cost, energy utilization, and noise.

EMPACTS faculty use community based projects to increase deeper learning of course content through "real-world" service experiences. Learners develop personal and interpersonal work and communication skills as they plan, execute and complete project goals together. Technology is used as a tool to solve problems and to publish the products of their learning experiences. Courses across a broad STEM curriculum integrate the EMPACTS project experience into the overall learning outcomes as part of the learning college mission of preparing 2Y graduates for future academic and/or workforce success. Since the program began in 2005, there have been over 200 completed projects/year. Student driven successes have led to the establishment of an EMPACTS Technology Corp, which is funded through scholarship and allows EMPACTS learners the opportunity to serve and learn from one another as "peer instructors." Engineering and 3D graphic design teams have written technology proposals and received funding for 3D printing replication projects, which have benefited the college as a whole through grant opportunities tied to these small scale successes. EMPACTS students engage in a variety of outreachprojects with area schools as they share the successes and joys of self directed, inquiry, project based learning. The EMPACTS Program has successfully trained faculty and students in the implementation of the model and conduct semester to semester and once a year workshops for college and K-12 faculty, who are interested in

    There is a long history of cooperation between students at the University of Colorado, Boulder and professional engineers and scientists at LASP, which has led to many successful space missions with direct student involvement. The recent student-led missions include the Student Nitric Oxide Explorer (SNOE, 1998 - 2002), the Student Dust Counter (SDC) on New Horizons (2006 - present), the Colorado Student Space Weather Experiment (CSSWE), being a very successful NSF CubeSat that launched in September 2012, and the NASA Miniature X-ray Solar Spectrometer (MinXSS) CubeSat (launch will be in early 2015). Students are involved in all aspects of the design, and they experience the full scope of the mission process from concept, to fabrication and test, and mission operations. A significant part of the student involvement in the CubeSat projects is gained by using the CubeSat development as a focal point for an existing two-semester course sequence in CU's Aerospace Engineering Sciences (AES) Department: the Space Hardware Design section of Graduate Projects I & II (ASEN 5018 & ASEN 6028). The goal of these courses is to teach graduate students how to design and build systems using a requirement-based approach and fundamental systems engineering practices. The two-semester sequence takes teams of about 15 students from requirements definition and preliminary design through manufacturing, integration, and testing. In addition to the design process, students learn key professional skills such as working effectively in groups, finding solutions to open-ended problems, and actually building a system to their own set of specifications. The partnership between AES and LASP allows us to include engineering professionals in the mix, thus more effectively training science and engineering students for future roles in the civilian or commercial space industry. The mentoring process with LASP engineers helps to mitigate risk of the inexperience of the students and ensures consistent

  16. Modelling of subsonic COIL with an arbitrary magnetic modulation

    Science.gov (United States)

    Beránek, Jaroslav; Rohlena, Karel

    2007-05-01

    The concept of 1D subsonic COIL model with a mixing length was generalized to include the influence of a variable magnetic field on the stimulated emission cross-section. Equations describing the chemical kinetics were solved taking into account together with the gas temperature also a simplified mixing model of oxygen and iodine molecules. With the external time variable magnetic field the model is no longer stationary. A transformation in the system moving with the mixture reduces partial differential equations to ordinary equations in time with initial conditions given either by the stationary flow at the moment when the magnetic field is switched on combined with the boundary conditions at the injector. Advantage of this procedure is a possibility to consider an arbitrary temporal dependence of the imposed magnetic field and to calculate directly the response of the laser output. The method was applied to model the experimental data measured with the subsonic version of the COIL device in the Institute of Physics, Prague, where the applied magnetic field had a saw-tooth dependence. We found that various values characterizing the laser performance, such as the power density distribution over the active zone cross-section, may have a fairly complicated structure given by combined effects of the delayed reaction to the magnetic switching and the flow velocity. This is necessarily translated in a time dependent spatial inhomogeneity of output beam intensity profile.

  17. A modification of the successive projections algorithm for spectral variable selection in the presence of unknown interferents.

    This work proposes a modification to the successive projections algorithm (SPA) aimed at selecting spectral variables for multiple linear regression (MLR) in the presence of unknown interferents not included in the calibration data set. The modified algorithm favours the selection of variables in which the effect of the interferent is less pronounced. The proposed procedure can be regarded as an adaptive modelling technique, because the spectral features of the samples to be analyzed are considered in the variable selection process. The advantages of this new approach are demonstrated in two analytical problems, namely (1) ultraviolet-visible spectrometric determination of tartrazine, allure red and sunset yellow in aqueous solutions under the interference of erythrosine, and (2) near-infrared spectrometric determination of ethanol in gasoline under the interference of toluene. In these case studies, the performance of conventional MLR-SPA models is substantially degraded by the presence of the interferent. This problem is circumvented by applying the proposed Adaptive MLR-SPA approach, which results in prediction errors smaller than those obtained by three other multivariate calibration techniques, namely stepwise regression, full-spectrum partial-least-squares (PLS) and PLS with variables selected by a genetic algorithm. An inspection of the variable selection results reveals that the Adaptive approach successfully avoids spectral regions in which the interference is more intense. Copyright © 2011 Elsevier B.V.

    This paper reviews the past 5 years of experiments utilizing radiographic techniques to study defiagration in thermal explosions in HMX based formulations. Details of triggering and timing synchronization are given. Radiographic images collected using both protons and x-rays are presented. Comparisons of experiments with varying size, case confinement, binder, and synchronization are presented. Techniques for quantifying the data in the images are presented and a mechanism for post-ignition burn propagation in a thermal explosion is discussed. From these experiments, we have observed a mechanism for sub-sonic defiagration with both gas phase convective and solid phase conductive burning. The convective front velocity is directly measured from the radiographic images and consumes only a small fraction of the HE. It lights the HE as it passes beginning the slower solid state conductive burn process. This mechanism is used to create a model to simulate the radiographic results and a comparison will be shown.

    Tai, T. C.; Kidwell, G. H., Jr.

    1984-01-01

    A numerical procedure for optimizing the design of the circulation control airfoil for use at high subsonic speeds is presented. The procedure consists of an optimization scheme coupled with a viscous potential flow analysis for the blowing jet. The desired airfoil is defined by a combination of three baseline shapes (cambered ellipse and cambered ellipse with drooped and spiraled trailing edges). The coefficients of these shapes are used as design variables in the optimization process. Under the constraints of lift augmentation and lift-to-drag ratios, the airfoil, optimized at free-stream Mach 0.54 and alpha = -2 degrees can be characterized as a cambered ellipse with a drooped trailing edge. Experimental tests support the performance improvement predicted by numerical optimization.

    Enhanced geothermal systems (EGS) are gaining in popularity as a technology that can be used to increase areas for geothermal resource procurement. One of the most important factors in the success of an EGS system is the success of the subsurface reservoir that is used for fluid flow and heat mining through advection. There are numerous challenges in stimulating a successful reservoir, including maintaining flow rates, minimizing leak off, preventing short-circuiting, and reducing the risk of microseismicity associated with subsurface activity. Understanding past examples of stimulation can be invaluable in addressing these challenges. This study provides an overview of stimulation methods that have been employed in EGS systems from 1974-2017. We include all geothermal reservoirs and demonstration projects that have experienced hydrofracturing, chemical stimulation, and induced thermal stress for a comprehensive list. We also examine different metrics and measures of success in geothermal reservoir stimulation to draw conclusions and provide recommendations for future projects. Multiple project characteristics are reported including geologic setting, stress conditions, reservoir temperature, injection specifics, resulting microseismicity, and overall project goals. Insight into optimal and unproductive stimulation methods is crucial to conserving mental capital, utilizing project funding, and ensuring EGS technology advances as efficiently as possible.

    This report summarizes the Truss Braced Wing (TBW) work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, consisting of Boeing Research and Technology, Boeing Commercial Airplanes, General Electric, Georgia Tech, Virginia Tech, NextGen Aeronautics, and Microcraft. A multi-disciplinary optimization (MDO) environment defined the geometry that was further refined for the updated SUGAR High TBW configuration. Airfoil shapes were tested in the NASA TCT facility, and an aeroelastic model was tested in the NASA TDT facility. Flutter suppression was successfully demonstrated using control laws derived from test system ID data and analysis models. Aeroelastic impacts for the TBW design are manageable and smaller than assumed in Phase I. Flutter analysis of TBW designs need to include pre-load and large displacement non-linear effects to obtain a reasonable match to test data. With the updated performance and sizing, fuel burn and energy use is reduced by 54% compared to the SUGAR Free current technology Baseline (Goal 60%). Use of the unducted fan version of the engine reduces fuel burn and energy by 56% compared to the Baseline. Technology development roadmaps were updated, and an airport compatibility analysis established feasibility of a folding wing aircraft at existing airports.

    This Test Report summarizes the Truss Braced Wing (TBW) Aeroelastic Test (Task 3.1) work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, which includes the time period of February 2012 through June 2014. The team consisted of Boeing Research and Technology, Boeing Commercial Airplanes, Virginia Tech, and NextGen Aeronautics. The model was fabricated by NextGen Aeronautics and designed to meet dynamically scaled requirements from the sized full scale TBW FEM. The test of the dynamically scaled SUGAR TBW half model was broken up into open loop testing in December 2013 and closed loop testing from January 2014 to April 2014. Results showed the flutter mechanism to primarily be a coalescence of 2nd bending mode and 1st torsion mode around 10 Hz, as predicted by analysis. Results also showed significant change in flutter speed as angle of attack was varied. This nonlinear behavior can be explained by including preload and large displacement changes to the structural stiffness and mass matrices in the flutter analysis. Control laws derived from both test system ID and FEM19 state space models were successful in suppressing flutter. The control laws were robust and suppressed flutter for a variety of Mach, dynamic pressures, and angle of attacks investigated.

    1995-01-01

    Prediction of the detailed dynamic behavior in rocket propellant feed systems and engines and other such high-energy fluid systems requires precise analysis to assure structural performance. Designs sometimes require placement of bluff bodies in a flow passage. Additionally, there are flexibilities in ducts, liners, and piping systems. A design handbook and interactive data base have been developed for assessing flow/structural interactions to be used as a tool in design and development, to evaluate applicable geometries before problems develop, or to eliminate or minimize problems with existing hardware. This is a compilation of analytical/empirical data and techniques to evaluate detailed dynamic characteristics of both the fluid and structures. These techniques have direct applicability to rocket engine internal flow passages, hot gas drive systems, and vehicle propellant feed systems. Organization of the handbook is by basic geometries for estimating Strouhal numbers, added mass effects, mode shapes for various end constraints, critical onset flow conditions, and possible structural response amplitudes. Emphasis is on dense fluids and high structural loading potential for fatigue at low subsonic flow speeds where high-frequency excitations are possible. Avoidance and corrective measure illustrations are presented together with analytical curve fits for predictions compiled from a comprehensive data base.

    The most prolific star formers in cosmological history lie in a regime where dense filament structures carried substantial mass into the galaxy to sustain star formation without producing a shock. However, hydrodynamic instabilities present on the filament surface limit the ability of such structures to deliver dense matter deeply enough to sustain star formation. Simulations lack the finite resolution necessary to allow fair treatment of the instabilities present at the stream boundary. Using the Omega EP laser, we simulate this mode of galaxy formation with a cold, dense, filament structure within a hotter, subsonic flow and observe the interface evolution. Machined surface perturbations stimulate the development of the Kelvin-Helmholtz (KH) instability due to the resultant shear between the two media. A spherical crystal imaging system produces high-resolution radiographs of the KH structures along the filament surface. The results from the first experiments of this kind, using a rod with single-mode, long-wavelength modulations, will be discussed. This work is funded by the U.S. Department of Energy, through the NNSA-DS and SC-OFES Joint Program in High-Energy-Density Laboratory Plasmas, Grant Number DE-NA0002956, and the National Laser User Facility Program, Grant Number DE-NA0002719, and through.

    2013-01-01

    National Aeronautics and Space Administration Dryden Flight Research Center acquired a Gulfstream III (GIII) aircraft to serve as a testbed for aeronautics flight research experiments. The aircraft is referred to as SCRAT, which stands for SubsoniC Research Aircraft Testbed. The aircraft's mission is to perform aeronautics research; more specifically raising the Technology Readiness Level (TRL) of advanced technologies through flight demonstrations and gathering high-quality research data suitable for verifying the technologies, and validating design and analysis tools. The SCRAT has the ability to conduct a range of flight research experiments throughout a transport class aircraft's flight envelope. Experiments ranging from flight-testing of a new aircraft system or sensor to those requiring structural and aerodynamic modifications to the aircraft can be accomplished. The aircraft has been modified to include an instrumentation system and sensors necessary to conduct flight research experiments along with a telemetry capability. An instrumentation power distribution system was installed to accommodate the instrumentation system and future experiments. An engineering simulation of the SCRAT has been developed to aid in integrating research experiments. A series of baseline aircraft characterization flights has been flown that gathered flight data to aid in developing and integrating future research experiments. This paper describes the SCRAT's research systems and capabilities.

  11. Chaos control for the plates subjected to subsonic flow

    Norouzi, Hamed; Younesian, Davood

    2016-07-01

    The suppression of chaotic motion in viscoelastic plates driven by external subsonic air flow is studied. Nonlinear oscillation of the plate is modeled by the von-Kármán plate theory. The fluid-solid interaction is taken into account. Galerkin's approach is employed to transform the partial differential equations of the system into the time domain. The corresponding homoclinic orbits of the unperturbed Hamiltonian system are obtained. In order to study the chaotic behavior of the plate, Melnikov's integral is analytically applied and the threshold of the excitation amplitude and frequency for the occurrence of chaos is presented. It is found that adding a parametric perturbation to the system in terms of an excitation with the same frequency of the external force can lead to eliminate chaos. Variations of the Lyapunov exponent and bifurcation diagrams are provided to analyze the chaotic and periodic responses. Two perturbation-based control strategies are proposed. In the first scenario, the amplitude of control forces reads a constant value that should be precisely determined. In the second strategy, this amplitude can be proportional to the deflection of the plate. The performance of each controller is investigated and it is found that the second scenario would be more efficient.

  12. Subsonic leaky Rayleigh waves at liquid-solid interfaces.

    2002-05-01

    The paper is devoted to the study of leaky Rayleigh waves at liquid-solid interfaces close to the border of the existence domain of these modes. The real and complex roots of the secular equation are computed for interface waves at the boundary between water and a binary isotropic alloy of gold and silver with continuously variable composition. The change of composition of the alloy allows one to cross a critical velocity for the existence of leaky waves. It is shown that, contrary to popular opinion, the critical velocity does not coincide with the phase velocity of bulk waves in liquid. The true threshold velocity is found to be smaller, the correction being of about 1.45%. Attention is also drawn to the fact that using the real part of the complex phase velocity as a velocity of leaky waves gives only approximate value. The most interesting feature of the waves under consideration is the presence of energy leakage in the subsonic range of the phase velocities where, at first glance, any radiation by harmonic waves is not permitted. A simple physical explanation of this radiation with due regard for inhomogeneity of radiated and radiating waves is given. The controversial question of the existence of leaky Rayleigh waves at a water/ice interface is reexamined. It is shown that the solution considered previously as a leaky wave is in fact the solution of the bulk-wave-reflection problem for inhomogeneous waves.

  13. Experimental investigation on a high subsonic compressor cascade flow

    2015-08-01

    Full Text Available With the aim of deepening the understanding of high-speed compressor cascade flow, this paper reports an experimental study on NACA-65 K48 compressor cascade with high subsonic inlet flow. With the increase of passage pressurizing ability, endwall boundary layer behavior is deteriorated, and the transition zone is extended from suction surface to the endwall as the adverse pressure gradient increases. Cross flow from endwall to midspan, mixing of corner boundary layer and the main stream, and reversal flow on the suction surface are caused by corner separation vortex structures. Passage vortex is the main corner separation vortex. During its movement downstream, the size grows bigger while the rotating direction changes, forming a limiting circle. With higher incidence, corner separation is further deteriorated, leading to higher flow loss. Meanwhile, corner separation structure, flow mixing characteristics and flow loss distribution vary a lot with the change of incidence. Compared with low aspect-ratio model, corner separation of high aspect-ratio model moves away from the endwall and is more sufficiently developed downstream the cascade. Results obtained present details of high-speed compressor cascade flow, which is rare in the relating research fields and is beneficial to mechanism analysis, aerodynamic optimization and flow control design.

    The Department of the Interior (DOI) partnered with the National Fish and Wildlife Foundation (NFWF) to administer an external funding competition to support coastal resilience projects in the region affected by Hurricane Sandy. The projects complement the DOI Bureau-led projects, but are led by state and local governments, universities, non-profits, community groups, tribes, and other non-Federal entities. In total, the Hurricane Sandy Resilience Program invested over $750 million in approximately 180 projects to repair damage and improve the resilience of habitats, communities and infrastructure to future storms and sea level rise. Project activities include waterway connection and opening, living shoreline, marsh restoration, community resilience planning, data/mapping/modeling, and beach and dune restoration. DOI and NFWF initiated a resilience assessment in 2015 to evaluate the impact of this investment. The assessment began by clarifying the program's resilience goals and the development of ecological and socio-economic metrics across the project activities. Using these metrics, the evaluation is assessing the ecological and community outcomes, cost effectiveness of activities, improved scientific understanding, and temporal and spatial scaling of benefits across resilience activities. Recognizing the unique opportunity afforded by the scale and distribution of projects, NFWF and DOI have invested in monitoring through 2024 to better understand how these projects perform over time. This presentation will describe the evaluation questions, approach, long-term monitoring, online metrics portal, and findings to date.

    The need for environmental protection challenges societies to deal with difficult problems because strategies designed by scientists to protect the environment often create negative effects on impoverished local residents. We investigated the effects of China's national and regional policies related to environmental protection and rehabilitation projects in inland river basins, by studying the effect of projects in the Heihe and Shiyang river basins, in northwest China. Interviews and surveys were conducted at 30 sites in the lower reaches of these two arid basins, an area that has experienced severe ecological degradation. The survey results show the ecological rehabilitation projects adversely affected the livelihoods of 70.35% of foresters, 64.89% of farmers and 62.24% of herders in the Minqing region in the lower Shiyang River Basin; also, the projects negatively affected 51.9% of residents in the Ejin Qi in the lower Heihe River Basin. This caused 16.33% of foresters, 39.90% of farmers and 45.32% of herders in the Minqing region to not support the project and 37.5% of residents in the Ejin Qi region said they will deforest and graze again after the project ends. The negative impacts of the policies connected to the projects cause these attitudes. The projects prohibit felling and grazing and require residents to give up groundwater mining; this results in a great amount of uncompensated economic loss to them. Extensive survey data document the concerns of local residents, concerns that are supported by the calculation of actual incomes. In addition, the surveys results show poorer interviewees believe the projects greatly affected their livelihoods. While citizens in this region support environment protection work, the poor require considerable assistance if one expects them to support this type of work. Governmental assistance can greatly improve their living conditions, and hence encourage them to participate in and support the implementation of the projects

    The Environmental Health/Home Safety Education Project (Proyecto de Salud Ambiental y Seguridad en el Hogar) has been developed in response to a wide array of severe and often preventable environmental health issues occurring in and around homes on the U.S.-Mexico border. Utilizing well-trained community members, called promotoras , homes are visited and assessed for potential environmental hazards, including home fire and food safety issues. Data analyzed from project years 2002 to 2005 shows a significant impact in knowledge levels and initial behavior change among targeted participants as it relates to fire and food safety issues. Since the initiation of the project in 1999, hundreds of participants have improved their quality of life by making their homes safer. The project has proven to be sustainable, replicable, flexible, and attractive to funders.

  3. Final Verification Success Story Using the Triad Approach at the Oak Ridge National Laboratory's Melton Valley Soils and Sediment Project

    2006-01-01

    The United States Environmental Protection Agency recently published guidance on the Triad approach, which supports the use of smarter, faster, and better technologies and work strategies during environmental site assessment, characterization, and cleanup. The Melton Valley Soils and Sediment Project (Project) at the Oak Ridge National Laboratory embraced this three-pronged approach to characterize contaminants in soil/sediment across the 1000-acre Melton Valley Watershed. Systematic Project Planning is the first of three prongs in the Triad approach. Management initiated Project activities by identifying key technical personnel, included regulators early in the planning phase, researched technologies, and identified available resources necessary to meet Project objectives. Dynamic Work Strategies is the second prong of the Triad approach. Core Team members, including State and Federal regulators, helped develop a Sampling and Analysis Plan that allowed experienced field managers to make real-time, in-the-field decisions and, thus, to adjust to conditions unanticipated during the planning phase. Real-time Measurement Technologies is the third and last prong of the Triad approach. To expedite decision-making, the Project incorporated multiple in-field technologies, including global positioning system equipment integrated with field screening instrumentation, magnetometers for utility clearance, and an on-site gamma spectrometer (spec) for rapid contaminant speciation and quantification. As a result of a relatively complex but highly efficient program, a Project field staff of eight collected approximately 1900 soil samples for on-site gamma spec analysis (twenty percent were also shipped for off-site analyses), 4.7 million gamma radiation measurements, 1000 systematic beta radiation measurements, and 3600 systematic dose rate measurements between July 1, 2004, and October 31, 2005. The site database previously contained results for less than 500 soil samples dating

    The translation of healthcare research into practice is typically challenging and limited in effectiveness. The Theoretical Domains Framework (TDF) identifies 12 domains of behaviour determinants which can be used to understand the principles of behavioural change, a key factor influencing implementation. The Accelerated Chest pain Risk Evaluation (ACRE) project has successfully translated research into practice, by implementing an intervention to improve the assessment of low to intermediate risk patients presenting to emergency departments (EDs) with chest pain. The aims of this paper are to describe use of the TDF to determine which factors successfully influenced implementation and to describe use of the TDF as a tool to evaluate implementation efforts and which domains are most relevant to successful implementation. A 30-item questionnaire targeting clinicians was developed using the TDF as a guide. Questions encompassed ten of the domains of the TDF: Knowledge; Skills; Social/professional role and identity; Beliefs about capabilities; Optimism; Beliefs about consequences; Intentions; Memory, attention and decision processes; Environmental context and resources; and Social influences. Sixty-three of 176 stakeholders (36 %) responded to the questionnaire. Responses for all scales showed that respondents were highly favourable to all aspects of the implementation. Scales with the highest mean responses were Intentions, Knowledge, and Optimism, suggesting that initial education and awareness strategies around the ACRE project were effective. Scales with the lowest mean responses were Environmental context and resources, and Social influences, perhaps highlighting that implementation planning could have benefitted from further consideration of the factors underlying these scales. The ACRE project was successful, and therefore, a perfect case study for understanding factors which drive implementation success. The overwhelmingly positive response suggests that it

    Berns, Darren H.; Sankovic, John M.; Sarmiento, Charles J.

    1993-01-01

    To investigate high frequency arc instabilities observed in subsonic-arc-attachment thrusters, a 3 kW, segmented-anode arcjet was designed and tested using hydrogen as the propellant. The thruster nozzle geometry was scaled from a 30 kW design previously tested in the 1960's. By observing the current to each segment and the arc voltage, it was determined that the 75-200 kHz instabilities were results of axial movements of the arc anode attachment point. The arc attachment point was fully contained in the subsonic portion of the nozzle for nearly all flow rates. The effects of isolating selected segments were investigated. In some cases, forcing the arc downstream caused the restrike to cease. Finally, decreasing the background pressure from 18 Pa to 0.05 Pa affected the pressure distribution in the nozzle, including the pressure in the subsonic arc chamber.

The thruster nozzle geometry was scaled from a 30 kW design previously tested in the 1960's. By observing the current to each segment and the arc voltage, it was determined that the 75-200 kHz instabilities were results of axial movements of the arc anode attachment point. The arc attachment point was fully contained in the subsonic portion of the nozzle for nearly all flow rates. The effects of isolating selected segments were investigated. In some cases, forcing the arc downstream caused the restrike to cease. Finally, decreasing the background pressure from 18 to 0.05 Pa affected the pressure distribution in the nozzle including the pressure in the subsonic arc chamber.

    The project called Adotta scienza e arte nella tua classe ("Adopt Science and Art in your class"), on the interconnection between science and art, has been addressed to the Italian secondary middle and high school involving more than 200 teachers and about 2200 students. The main purpose of this project is to make the young students aware of the strong link between science and art is a unique cultural and interdisciplinary occasion. To reach this goal, the Adotta project asked students to produce an artwork inspired by the interpretation of a quotation among a hundred commented quotes by physicists, mathematicians, scientist, writers, artists, accompanied by an original short sentence written by students themselves. More than 1000 artworks have been produced and collected in two galleries on Facebook. From their analysis emerges the students' feeling about science, which is usually associated to human brain, based on mathematical laws and related to technological progress, but it is also a powerful tool that should be responsibly used. This project also valorizes teachers' role in scientific education through activities that encourage students to recognize science in every aspect of their lives.

    Heterogeneous chemistry of HCl, as a main reservoir of chlorine content gases, has been considered after plume cooling and ice particle formation. The HCl, HNO{sub 3}, N{sub 2}O{sub 5} uptake efficiencies by frozen water were obtained in a Knudsen-cell flow reactor at the subsonic cruise conditions. The formation of ice particles in the plume of subsonic aircraft is simulated to describe the kinetics of gaseous HCl loss due to heterogeneous processes. It is shown that the HCl uptake by frozen water particles may play an important role in the gaseous HCl depletion in the aircraft plume. (author) 14 refs.

    Tseng, K.; Morino, L.

    1975-01-01

    A general theory for study, oscillatory or fully unsteady potential compressible aerodynamics around complex configurations is presented. Using the finite-element method to discretize the space problem, one obtains a set of differential-delay equations in time relating the potential to its normal derivative which is expressed in terms of the generalized coordinates of the structure. For oscillatory flow, the motion consists of sinusoidal oscillations around a steady, subsonic or supersonic flow. For fully unsteady flow, the motion is assumed to consist of constant subsonic or supersonic speed for time t or = 0 and of small perturbations around the steady state for time t 0.

  12. Interaction between plasma synthetic jet and subsonic turbulent boundary layer

    2017-04-01

    This paper experimentally investigates the interaction between a plasma synthetic jet (PSJ) and a subsonic turbulent boundary layer (TBL) using a hotwire anemometer and phase-locked particle imaging velocimetry. The PSJ is interacting with a fully developed turbulent boundary layer developing on the flat wall of a square wind tunnel section of 1.7 m length. The Reynolds number based on the freestream velocity (U∞ = 20 m/s) and the boundary layer thickness (δ99 = 34.5 mm) at the location of interaction is 44 400. A large-volume (1696 mm3) three-electrode plasma synthetic jet actuator (PSJA) with a round exit orifice (D = 2 mm) is adopted to produce high-speed (92 m/s) and short-duration (Tjet = 1 ms) pulsed jets. The exit velocity variation of the adopted PSJA in a crossflow is shown to remain almost identical to that in quiescent conditions. However, the flow structures emanating from the interaction between the PSJ and the TBL are significantly different from what were observed in quiescent conditions. In the midspan xy plane (z = 0 mm), the erupted jet body initially follows a wall-normal trajectory accompanied by the formation of a distinctive front vortex ring. After three convective time scales the jet bends to the crossflow, thus limiting the peak penetration depth to approximately 0.58δ99. Comparison of the normalized jet trajectories indicates that the penetration ability of the PSJ is less than steady jets with the same momentum flow velocity. Prior to the jet diminishing, a recirculation region is observed in the leeward side of the jet body, experiencing first an expansion and then a contraction in the area. In the cross-stream yz plane, the signature structure of jets in a crossflow, the counter-rotating vortex pair (CVP), transports high-momentum flow from the outer layer to the near-wall region, leading to a fuller velocity profile and a drop in the boundary layer shape factor (1.3 to 1.2). In contrast to steady jets, the CVP produced by the PSJ

    Introduction: The Disease Management Project Breast Cancer (DMP Breast Cancer) was first launched in Hesse in 2004. The project is supported by the health insurance companies in Hesse and the Professional Association of Gynaecologists in Hesse. The aim is to offer structured treatment programmes to all women diagnosed with breast cancer in Hesse by creating intersectoral cooperations between coordinating clinics, associated hospitals and gynaecologists in private practice who registered in the DMP programme. Method: Between 1 January 2005 and 30 June 2011, 13 973 women were enrolled in the DMP programme. Results: After data cleansing, survival rates were calculated for a total of 11 214 women. The 5-year overall survival (OS) rate was 86.3 %; survival rates according to tumour stage on presentation were 92.2 % (pT1) and 82.3 % (pT2), respectively. The impact of steroid hormone receptor status on survival (87.8 % for receptor-positive cancers vs. 78.9 % for receptor-negative cancers) and of age at first diagnosis on survival (≤ 35 years = 91 %) were calculated. Conclusion: The project showed that intersectoral cooperation led to significant improvements in the quality of treatment over time, as measured by quality indicators and outcomes after treatment.

    This article describes the activities and interim outcomes of a multi-site development project called Project Career, designed to promote cognitive support technology (CST) use and employment success for college and university students with traumatic brain injuries (TBIs). To obtain early intervention results from participants in Project Career's first 18 months of operation. Fifty-six students with TBI have participated to date across three implementation sites in Massachusetts, Ohio, and West Virginia, with 25 of these participants being military veterans. Descriptive analyses provide information regarding the participants, the barriers they face due to their TBI in obtaining a post-secondary education, and the impact services provided by Project Career have had to date in ameliorating those difficulties. Inferential statistical analyses provide preliminary results regarding program effectiveness. Preliminary results indicate the program is encouraging students to use CST strategies in the form of iPads and cognitive enhancement applications (also known as 'apps'). Significant results indicate participants are more positive, independent, and social; participants have a more positive attitude toward technology after six months in the program; and participants reported significantly improved experiences with technology during their first six months in the program. Participating students are actively preparing for their careers after graduation through a wide range of intensive vocational supports provided by project staff members.

    1986-01-01

    Taken together as stones in a mosaic, the individual successes and failures of various nuclear plant construction programs begin to form a larger picture. Certain prerequisites to good experience become apparent. They are: agreement of need, constancy of purpose, rationalization of vendor/utility organizations, stable regulatory environment and plant standardization. Equally important is a belief that power plant costs can be contained and the commitment to do something about them. A Calvinist approach to spending, namely that costs are preordained and cannot be affected by mere men, is self-defeating. There is no escaping these conclusions nor the need to implement them

    2014-10-01

    Full Text Available Growth and fiscal policy conducive to economic development have been severely jeopardized in most NATO member countries since 2008. In sharp contrast, China has experienced only a relatively slower GDP growth, which it has mitigated with a fiscally expansionary outlook. Under these conditions, when can we expect the politico-military position of NATO to be challenged? This paper surveys amphibious force projection capabilities in six countries: the USA, the UK, France, Russia, India and the People's Republic of China (PRC. An assessment of the current capability for aircraft carrier building and a survey of carrier-related ambitions is undertaken to offer projections of probable aircraft carrier fleets by 2030. The three non-NATO countries are far better positioned to build aircraft carriers than the three NATO members, with China in the lead. Nevertheless, there is a high probability of the continued military dominance of the USA and NATO, but also of a military build-up focusing on the Indian Ocean.

    2011-01-01

    The National Aeronautics and Space Administration's Dryden Flight Research Center completed flight testing of adaptive controls research on the Full-Scale Advance Systems Testbed (FAST) in January of 2011. The research addressed technical challenges involved with reducing risk in an increasingly complex and dynamic national airspace. Specific challenges lie with the development of validated, multidisciplinary, integrated aircraft control design tools and techniques to enable safe flight in the presence of adverse conditions such as structural damage, control surface failures, or aerodynamic upsets. The testbed is an F-18 aircraft serving as a full-scale vehicle to test and validate adaptive flight control research and lends a significant confidence to the development, maturation, and acceptance process of incorporating adaptive control laws into follow-on research and the operational environment. The experimental systems integrated into FAST were designed to allow for flexible yet safe flight test evaluation and validation of modern adaptive control technologies and revolve around two major hardware upgrades: the modification of Production Support Flight Control Computers (PSFCC) and integration of two, fourth-generation Airborne Research Test Systems (ARTS). Post-hardware integration verification and validation provided the foundation for safe flight test of Nonlinear Dynamic Inversion and Model Reference Aircraft Control adaptive control law experiments. To ensure success of flight in terms of cost, schedule, and test results, emphasis on risk management was incorporated into early stages of design and flight test planning and continued through the execution of each flight test mission. Specific consideration was made to incorporate safety features within the hardware and software to alleviate user demands as well as into test processes and training to reduce human factor impacts to safe and successful flight test. This paper describes the research configuration

    Full Text Available Mutual relations between family and professional life have been for many years one of the most important fields of research in economics, sociology and, more and more often, pedagogy, which focuses on searching for factors protecting from the development of burnout syndrome and aims at increasing the effectiveness of pedagogic efforts. Due to the above, this article, being a draft of a research project, is dedicated to the facilitating effect of family life on professional life of the penitentiary staff. The authors take a stance that the feeling of satisfaction from family life can not only significantly neutralize the feeling of failure but, primarily, contribute to the search for more and more innovative forms of work.

    Under the auspices of the National Science Foundation's Advanced Technological Education Grant and the Department of Education's Title V/HSI Grant, Palomar College students from a variety of disciplines have not only been exposed to the high growth field of geospatial technologies, but have also been exposed to the geosciences and regional environmental issues in their GIS courses. By integrating introductory Physical Geography topics such as liquefaction, subsidence, ozone depletion, plate tectonics, and coastal processes in the introductory GIS curriculum, GIS students from fields ranging from Archaeology to Zoology were exposed to basic geosciences theories in a series of hands-on interactive exercises, while gaining competency in geospatial technologies. Additionally, as students undertake interdisciplinary service learning projects under the supervision of experts in the private, governmental, and nonprofit sectors, students were introduced to the STEM workplace, forged invaluable professional connections, applied their classroom knowledge to advance research (e.g. analyzing migration patterns of cephalopod), and analyzed regional environmental issues (e.g. distribution of invasive plants in state natural preserves). In order to further the retention and completion of students in GIS, Earth Science, and other STEM courses, a STEM Student Learning Center was constructed, whereby students can receive services such as supplemental instruction, walk-in tutoring, STEM counseling and transfer advising, as well as faculty and peer mentoring.

    The National Health Disparities Report notes that Hispanics have poorer quality of care in 23 of 38 core measures. The result of this disparity is great personal and health system costs, which could be reduced. Prior studies have focused on access and language. We studied outcomes improvement. The purpose of this project was to develop a replicable theory-based outcomes improvement model for delivery of nursing care to Hispanic patients. The Leininger Sunrise Enabler approach was used to design a program specific to the cultural needs of a home care population. Outcome and Assessment Information Set (OASIS) data from 125 unduplicated home care patients were tracked. Nursing care delivery was analyzed using ethnographic research techniques. Delivery of nursing care using a culturally congruent approach reduced acute hospitalization and emergent care visits. Medication management and customer and nursing satisfaction also improved. National standards for culturally and linguistically appropriate services in health care help reduce healthcare disparities, but improving Hispanic outcomes requires moving beyond symptoms and symptom management to transcultural care. The estimated savings to the health care system are significant.

    Full Text Available Purpose—This paper aims to develop a unique instrument to be used for both assessing business ideas and monitoring the respective social enterprises while taking off, eventually IT-supported.Design/methodology/approach—A sample of 25 cases was selected—in the framework of a regional development project in the Horezu micro-region, Romania (the IDEALIS Project implementation is scheduled for 2011-2012. Each case corresponds to a business idea for starting-up a social enterprise (either agricultural co-operative or co-operative enterprise in the region. The first phase of this project is to assess the viability of each business idea, and the second phase is to monitor the social start-ups as they are taking off. In both phases an original decision method is used, implanted on a methodology to assess the business idea’s probability to succeed. This paper was prepared after the completion of the first phase while an IT application was considered as a vehicle to use the proposed method for monitoring the newly created social enterprises.Findings/results—The proposed instrument (ABIDIS: Assessing Business Ideas by the DISTEH method was successfully used to associate a score to each business idea and, consequently, to rank the respective social enterprises accordingly: the higher the rank, the higher the chances to succeed. It is expected that social enterprises are considered for financial aid according to this ranking.Research limitations/implications—ABIDIS instrument is more useful when analyzed against a database of similar social enterprises and/or compared to its own historic data (which is monitoring actually. Amid successful method development and its use for assessing the chances of the social enterprises’ ideas to succeed, the practical use of the proposed methodology for monitoring the recently established social enterprises is still in progress. Furthermore, the rightness of the assessment is a matter of time—as it is going

    The problem of subsonic flow past three-dimensional micro-electro-mechanical-type (MEMS-type) heating elements placed on a flat surface, where the MEMS devices have hump-shaped surfaces, is investigated using the triple-deck theory. The compressible Navier–Stokes equations supplemented by the energy equation are considered in the limit when the Reynolds number is large. The dimensions of the MEMS devices considered are such that the flow perturbations are governed by the three-dimensional subsonic triple-deck equations formulated with the aid of method of matched expansions. The linear analysis of these equations is presented and our results provide an insight into how the MEMS heating elements may be used to positively control the local flow properties. (paper)

  11. Efficient solutions to the Euler equations for supersonic flow with embedded subsonic regions

    Science.gov (United States)

    Walters, Robert W.; Dwoyer, Douglas L.

    1987-01-01

    A line Gauss-Seidel (LGS) relaxation algorithm in conjunction with a one-parameter family of upwind discretizations of the Euler equations in two dimensions is described. Convergence of the basic algorithm to the steady state is quadratic for fully supersonic flows and is linear for other flows. This is in contrast to the block alternating direction implicit methods (either central or upwind differenced) and the upwind biased relaxation schemes, all of which converge linearly, independent of the flow regime. Moreover, the algorithm presented herein is easily coupled with methods to detect regions of subsonic flow embedded in supersonic flow. This allows marching by lines in the supersonic regions, converging each line quadratically, and iterating in the subsonic regions, and yields a very efficient iteration strategy. Numerical results are presented for two-dimensional supersonic and transonic flows containing oblique and normal shock waves which confirm the efficiency of the iteration strategy.

    This paper proposes a new variable selection method for nonlinear multivariate calibration, combining the Successive Projections Algorithm for interval selection (iSPA) with the Kernel Partial Least Squares (Kernel-PLS) modelling technique. The proposed iSPA-Kernel-PLS algorithm is employed in a case study involving a Vis-NIR spectrometric dataset with complex nonlinear features. The analytical problem consists of determining Brix and sucrose content in samples from a sugar production system, on the basis of transflectance spectra. As compared to full-spectrum Kernel-PLS, the iSPA-Kernel-PLS models involve a smaller number of variables and display statistically significant superiority in terms of accuracy and/or bias in the predictions.

    High-mass star forming regions are typically thought to be dominated by supersonic motions. We present combined Very Large Array and Green Bank Telescope (VLA+GBT) observations of NH3 (1,1) and (2,2) in the infrared dark cloud (IRDC) G035.39-00.33, tracing cold and dense gas down to scales of 0.07 pc. We find that, in contrast to previous, similar studies of IRDCs, more than a third of the fitted ammonia spectra show subsonic non-thermal motions (mean line width of 0.71 km s-1), and sonic Mach number distribution peaks around ℳ = 1. As possible observational and instrumental biases would only broaden the line profiles, our results provide strong upper limits to the actual value of ℳ, further strengthening our findings of narrow line widths. This finding calls for a re-evaluation of the role of turbulent dissipation and subsonic regions in massive-star and cluster formation. Based on our findings in G035.39, we further speculate that the coarser spectral resolution used in the previous VLA NH3 studies may have inhibited the detection of subsonic turbulence in IRDCs. The reduced turbulent support suggests that dynamically important magnetic fields of the 1 mG order would be required to support against possible gravitational collapse. Our results offer valuable input into the theories and simulations that aim to recreate the initial conditions of high-mass star and cluster formation.

    Full Text Available The article presents description and results of experiments on a ballistic track and subsonic wind tunnel. The subject of study is important an issue such as the assessment of the influence of the bullet head shape on the accuracy of shooting parameters at subsonic muzzle velocity. The article points to the features of examined precision of guided and unguided aircraft, refers to the main disturbing factors. In addition, it outlines the most well known ways to improve the flight precision of unguided munitions. The article presents the geometric parameters of bullets and their scale models used in the experiments. It describes the experimental facilities and the studies themselves. Particular attention is paid to the analysis of experimental air-gun firings. Results for different muzzle velocities of flight are compared. The paper notes an ambiguity in comparison of accuracy and head drag coefficient. The results are clearly aligned with the data purging in the little turbulent subsonic wind tunnel. The article describes in detail the use of the method for visualizing a structure of the flow for the delimitation of attached flow and estimation of stagnation zone. A revealed physical picture has comprehensive theoretical underpinning. The conclusions of the work also give a advices on selecting a bullet to have the best dispersion parameters.

    Determining fat content in hamburgers is very important to minimize or control the negative effects of fat on human health, effects such as cardiovascular diseases and obesity, which are caused by the high consumption of saturated fatty acids and cholesterol. This study proposed an alternative analytical method based on Near Infrared Spectroscopy (NIR) and Successive Projections Algorithm for interval selection in Partial Least Squares regression (iSPA-PLS) for fat content determination in commercial chicken hamburgers. For this, 70 hamburger samples with a fat content ranging from 14.27 to 32.12 mg kg- 1 were prepared based on the upper limit recommended by the Argentinean Food Codex, which is 20% (w w- 1). NIR spectra were then recorded and then preprocessed by applying different approaches: base line correction, SNV, MSC, and Savitzky-Golay smoothing. For comparison, full-spectrum PLS and the Interval PLS are also used. The best performance for the prediction set was obtained for the first derivative Savitzky-Golay smoothing with a second-order polynomial and window size of 19 points, achieving a coefficient of correlation of 0.94, RMSEP of 1.59 mg kg- 1, REP of 7.69% and RPD of 3.02. The proposed methodology represents an excellent alternative to the conventional Soxhlet extraction method, since waste generation is avoided, yet without the use of either chemical reagents or solvents, which follows the primary principles of Green Chemistry. The new method was successfully applied to chicken hamburger analysis, and the results agreed with those with reference values at a 95% confidence level, making it very attractive for routine analysis.

    A whole complement ELISA-based assay kit, primarily designed to screen for deficiencies in components of the complement system was developed during a European Union grant involving more than a dozen European scientists and a small-medium enterprise company (Wieslab, which later merged into Eurodiagnostica). The consortium was led by Prof. Mohamed R. Daha who had already guided a preceding European grant which prepared the ground for this endeavor to create a novel and sophisticated complement measurement tool. The final result of the grant was a scientific publication (Seelen et al., 2005, J. Immunol. Methods 296, 187-198) and a commercially available complement deficiency screening kit, WIESLAB(®) Complement system Screen. Thereafter, the group decided to carry on with a grant, located at Innsbruck Medical University, and supported by royalties and unrestricted educational grants from Eurodiagnostica, Malmö, entitled "Search for Applications for WIESLAB(®) Complement system Screen (SAW)" with the aim to look for further applications of this assay. During the latter project the group organized several scientific meetings aimed at evaluating the use of the assay as well as developing further branches of its platform. A look back over almost two decades reveals a great story of excellent research which was also commercially successful, fulfilling the aims of European Union grants. It is also a story of ageless friendship, only possible due to the vision and guidance of an exceptional manager: Moh Daha. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A systematic study is presented to guide the selection of a numerical solution strategy for URANS computation of a subsonic transport configuration undergoing simulated forced oscillation about its pitch axis. Forced oscillation is central to the prevalent wind tunnel methodology for quantifying aircraft dynamic stability derivatives from force and moment coefficients, which is the ultimate goal for the computational simulations. Extensive computations are performed that lead in key insights of the critical numerical parameters affecting solution convergence. A preliminary linear harmonic analysis is included to demonstrate the potential of extracting dynamic stability derivatives from computational solutions.

    Multi-Mission Earth Entry Vehicles (MMEEVs) are blunt-body vehicles designed with the purpose of transporting payloads from outer space to the surface of the Earth. To achieve high-reliability and minimum weight, MMEEVs avoid use of limited-reliability systems, such as parachutes, retro-rockets, and reaction control systems and rely on the natural aerodynamic stability of the vehicle throughout the Entry, Descent, and Landing (EDL) phase of flight. The Multi-Mission Systems Analysis for Planetary Entry (M-SAPE) parametric design tool is used to facilitate the design of MMEEVs for an array of missions and develop and visualize the trade space. Testing in NASA Langley?s Vertical Spin Tunnel (VST) was conducted to significantly improve M-SAPE?s subsonic aerodynamic models. Vehicle size and shape can be driven by entry flight path angle and speed, thermal protection system performance, terminal velocity limitations, payload mass and density, among other design parameters. The objectives of the VST testing were to define usable subsonic center of gravity limits, and aerodynamic parameters for 6-degree-of-freedom (6-DOF) simulations, for a range of MMEEV designs. The range of MMEEVs tested was from 1.8m down to 1.2m diameter. A backshell extender provided the ability to test a design with a much larger payload for the 1.2m MMEEV.

  9. On fluttering modes for aircraft wing model in subsonic air flow.

    2014-12-08

    The paper deals with unstable aeroelastic modes for aircraft wing model in subsonic, incompressible, inviscid air flow. In recent author's papers asymptotic, spectral and stability analysis of the model has been carried out. The model is governed by a system of two coupled integrodifferential equations and a two-parameter family of boundary conditions modelling action of self-straining actuators. The Laplace transform of the solution is given in terms of the 'generalized resolvent operator', which is a meromorphic operator-valued function of the spectral parameter λ, whose poles are called the aeroelastic modes. The residues at these poles are constructed from the corresponding mode shapes. The spectral characteristics of the model are asymptotically close to the ones of a simpler system, which is called the reduced model. For the reduced model, the following result is shown: for each value of subsonic speed, there exists a radius such that all aeroelastic modes located outside the circle of this radius centred at zero are stable. Unstable modes, whose number is always finite, can occur only inside this 'circle of instability'. Explicit estimate of the 'instability radius' in terms of model parameters is given.

    A wind tunnel investigation was conducted on a generic, high-wing transport model in the Langley 14- by 22-Foot Subsonic Tunnel. This report contains pressure data that document effects of various model configurations and free-stream conditions on wing pressure distributions. The untwisted wing incorporated a full-span, leading-edge Krueger flap and a part-span, double-slotted trailing-edge flap system. The trailing-edge flap was tested at four different deflection angles (20 deg, 30 deg, 40 deg, and 60 deg). Four wing configurations were tested: cruise, flaps only, Krueger flap only, and high lift (Krueger flap and flaps deployed). Tests were conducted at free-stream dynamic pressures of 20 psf to 60 psf with corresponding chord Reynolds numbers of 1.22 x 10(exp 6) to 2.11 x 10(exp 6) and Mach numbers of 0.12 to 0.20. The angles of attack presented range from 0 deg to 20 deg and were determined by wing configuration. The angle of sideslip ranged from minus 20 deg to 20 deg. In general, pressure distributions were relatively insensitive to free-stream speed with exceptions primarily at high angles of attack or high flap deflections. Increasing trailing-edge Krueger flap significantly reduced peak suction pressures and steep gradients on the wing at high angles of attack. Installation of the empennage had no effect on wing pressure distributions. Unpowered engine nacelles reduced suction pressures on the wing and the flaps.

    2017-04-01

    During the last decades, the number of large research projects has increased and therewith the requirement for multidisciplinary, multisectoral collaboration. Such complex and large-scale projects pose new competencies to form, manage, and use large, diverse teams as a competitive advantage. For complex projects the effort is magnified because multiple large international research consortia involving academic and non-academic partners, including big industries, NGOs, private and public bodies, all with cultural differences, individually discrepant expectations on teamwork and differences in the collaboration between national and multi-national administrations and research organisations, challenge the organisation and management of such multi-partner research consortia. How many partners are needed to establish and conduct collaboration with a multidisciplinary and multisectoral approach? How much personnel effort and what kinds of management techniques are required for such projects. This presentation identifies advantages and challenges of large research projects based on the experiences made in the context of an Innovative Training Network (ITN) project within Marie Skłodowska-Curie Actions of the European HORIZON 2020 program. Possible strategies are discussed to circumvent and avoid conflicts already at the beginning of the project.

    Three separate studies have shown operational, weight, and cost advantages for commercial subsonic transport aircraft using an all-electric secondary power system. The first study in 1982 showed that all-electric secondary power systems produced the second largest benefit compared to four other technology upgrades. The second study in 1985 showed a 10 percent weight and fuel savings using an all-electric high frequency (20 kHz) secondary power system. The last study in 1991 showed a 2 percent weight savings using today's technology (400 Hz) in an all-electric secondary power system. This paper will compare the 20 kHz and 400 Hz studies, analyze the 2 to 10 percent difference in weight savings and comment on the common benefits of the all-electric secondary power system.

The mesoscale transformation of gas composition was included on the base of the box model simulations. It has been found that the transformation of the exhausted gases in sub-grid scale is able to influence the results of the modelling. The radiative forcing caused by gas, sulfate aerosol, soot and contrails changes was estimated as big as 0.12-0.15 W/m{sup 2} (0.08 W/m{sup 2} globally and annually averaged). (author) 10 refs.

    While the emphasis of commercial, large aircraft engines is placed on low fuel consumption at high subsonic flight and the turbofan engines with high bypass ratio are dominating, high speed turboprop (ATP) of Mach 0.85 class with low fuel consumption are emerging. UHB with bypass ratio of 15 - 20 are planned with expection for application to intermediate size commercial planes. The pressure ratio is continuously rizing for improved cycle efficiency, reaching 35 - 40 in highest cases. Trends in design technique include: Use of computational aerodynamics and application of two-dimensional structural analysis and the digital simulation of engine characteristics. In the field of large, high bypass turbofan, serious competition is seen between GE and PNA at the thrust level of 5 - 60,000 pounds. Several engines for fighting planes have been approved in the type test and accepted as candidates for next generation of fighting planes including Japan. (15 figs, 36 refs)

    1978-01-01

    The Green's function method and the computer program SOUSSA (Steady Oscillatory and Unsteady Subsonic and Supersonic Aerodynamics) are reviewed. The Green's function method is applied to the fully unsteady potential equation yielding an integro-differential-delay equation. This equation is approximated by a set of differential-delay equations in time using the finite element method. The Laplace transform is used to yield a matrix relating the velocity potential to the normal wash. The matrix of the generalized aerodynamic forces is obtained by premultiplying and postmultiplying the matrices relating generalized forces to the potential and the normal wash by the generalized coordinates. The program SOUSSA is compared with existing numerical results. Results indicate that the program is not only general, flexible, and easy to use, but also accurate and fast.

    CERN Document Server

    Hariharan, S I

    2003-01-01

    This paper introduces a competitive computational approach for determining time-dependent far-field sound generated by subsonic flows around lifting airfoils. The procedure assumes the linearity of the sound field away from a bounded region surrounding the airfoil. It is assumed that the sound pressure on the boundary of this enclosed region (referred to as the Kirchhoff surface) is specified, possibly by another procedure such as solving the full Euler equations. Away from the Kirchhoff surface, the Euler equations are linearized about a uniform mean flow. It is well known that linearized Euler equations can be uncoupled into a scalar convective wave equation. However, due to the anisotropy present in the convective wave equation, it is difficult to compute solutions. In this context, direct numerical simulation of the convective wave equation requires proper numerical descriptions of far-field boundary conditions which is a non-trivial task. Moreover, if accurate far-field conditions can be formulated, the ...

    Reproductive success in wild- and first generation hatchery-origin spring Chinook males was examined by allowing the fish to compete for spawning opportunities in two sections of an observation stream. Behavioral observations were used to characterize the frequency of aggression and courting activities. Microsatellite DNA from each male and fry collected from the observation stream were used in pedigree analyses to estimate reproductive success. The coefficient of variation in male reproductive success equaled 116 and 86% in the two populations. No differences were detected in reproductive success due to hatchery or wild origin. Nor were any behavioral differences found between hatchery and wild males. Although statistical power was low due to intrinsic variation a great deal of overlap existed in the reproductive success values of hatchery and wild males. Significant disparities existed among the males on their ability to produce offspring. Males achieving high reproductive success mated with numerous females, were socially dominant, aggressive, and tended to stay in localized areas, courting and spawning with females that were adjacent to one another.

    Full Text Available O gerente de projeto, no seu papel de liderança, é um elemento-chave, tanto para o sucesso dos empreendimentos que coordena, quanto para a implementação das estratégias das organizações. Adicionalmente, pode se tornar importante para o futuro da organização, ao usar sua capacidade empreendedora para vislumbrar novas necessidades e oportunidades. No entanto, o gerente de projetos tem responsabilidades operacionais, de planejamento, monitoramento, contabilização e controle do projeto, que muitas vezes contrastam com as características de um empreendedor. Ante essas visões contraditórias sobre o gerente de projetos torna-se relevante avaliar se as características de um empreendedor quando incorporadas no perfil de um gerente se refletem em projetos mais bem sucedidos do ponto de vista empresarial. Para esta avaliação, foi feita uma pesquisa de campo com 164 gerentes de projetos, em sua maioria homens, com estudos de pós-graduação e bastante experientes. A análise não-paramétrica indicou uma tendência de se ter projetos mais bem sucedidos quanto maior for a tendência empreendedora do gerente de projetos. Houve um destaque para a tendência criativa, para a qual se pôde observar um impacto positivo sobre inúmeros critérios de sucesso.A project manager as a leader is the key element to assure the success of the ventures he/she is responsible for and to implement the organization strategies. Besides, the project manager can be very important to the future of the organization by applying entrepreneur skills aiming at needs and new opportunities. However, he/she has operational responsibilities such as planning, monitoring, and accounting and control of the project which can, some times, conflict with characteristics of an entrepreneur. Therefore, it is relevant to evaluate whether a project manager has the required entrepreneur skills which when combined the skills of a manger result in successful projects. In order to

    This report presents results of the work completed on the preliminary design of Fan 3 of NASA s 22-inch Fan Low Noise Research project. Fan 3 was intended to build on the experience gained from Fans 1 and 2 by demonstrating noise reduction technology that surpasses 1992 levels by 6 dB. The work was performed as part of NASA s Advanced Subsonic Technology (AST) program. Work on this task was conducted in the areas of CFD code validation, acoustic prediction and validation, rotor parametric studies, and fan exit guide vane (FEGV) studies up to the time when a NASA decision was made to cancel the design, fabrication and testing phases of the work. The scope of the program changed accordingly to concentrate on two subtasks: (1) Rig data analysis and CFD code validation and (2) Fan and FEGV optimization studies. The results of the CFD code validation work showed that this tool predicts 3D flowfield features well from the blade trailing edge to about a chord downstream. The CFD tool loses accuracy as the distance from the trailing edge increases beyond a blade chord. The comparisons of noise predictions to rig test data showed that both the tone noise tool and the broadband noise tool demonstrated reasonable agreement with the data to the degree that these tools can reliably be used for design work. The section on rig airflow and inlet separation analysis describes the method used to determine total fan airflow, shows the good agreement of predicted boundary layer profiles to measured profiles, and shows separation angles of attack ranging from 29.5 to 27deg for the range of airflows tested. The results of the rotor parametric studies were significant in leading to the decision not to pursue a new rotor design for Fan 3 and resulted in recommendations to concentrate efforts on FEGV stator designs. The ensuing parametric study on FEGV designs showed the potential for 8 to 10 EPNdB noise reduction relative to the baseline.

    The project called 'Adotta scienza e arte nella tua classe' ('Adopt Science and Art in your class'), on the interconnection between science and art, has been addressed to the Italian secondary middle and high school involving more than 200 teachers and about 2200 students. The main purpose of this project is to make the young students aware of the strong link between science and art is a unique cultural and interdisciplinary occasion. To reach this goal, the Adotta project asked students to produce an artwork inspired by the interpretation of a quotation among a hundred commented quotes by physicists, mathematicians, scientist, writers, artists, accompanied by an original short sentence written by students themselves. More than 1000 artworks have been produced and collected in two galleries on Facebook. From their analysis emerges the students’ feeling about science, which is usually associated to human brain, based on mathematical laws and related to technological progress, but it is also a powerful tool that should be responsibly used. This project also valorizes teachers’ role in scientific education through activities that encourage students to recognize science in every aspect of their lives.

    A logarithmic-singularity correction factor is derived for use in kernel function methods associated with Multhopp's subsonic lifting-surface theory. Because of the form of the factor, a relation was formulated between the numbers of chordwise and spanwise control points needed for good accuracy. This formulation is developed and discussed. Numerical results are given to show the improvement of the computation with the new correction factor.

    A growing need for broad dissemination of current scientific research and improved scientific literacy requires new models of professional development that allow for direct collaboration between educators and university researchers. One example is a project funded by the National Science Foundation (NSF) as part of a study titled, "Reconstructing 2500 years of environmental change at the periphery of Rome: Integrating paleoecology and socioeconomic history to understand human response to climate." This project involves a team of middle school teachers working with researchers at the University of Nevada, Reno (UNR) to gain first-hand knowledge in multidisciplinary research connecting science and society, and applies a similar approach in the classroom. In 2013, the team's science teacher traveled to Italy as a member of the science research group. A series of workshops introduced the remaining teachers to the research project. Teachers collaborated to develop a Project Based Learning (PBL) unit that incorporated Next Generation Science Standards and encompassed English, Social Studies, Math, and Science curricula using a pedagogical approach different from the single subject-based PBL's usually taught in their school district. The PBL unit draws on the NSF study and focuses on exploring the balance between economic and environmental issues surrounding local wetlands. In May 2014, 160 middle school students worked in groups to create and test a question about physio-chemical parameters in a nearby wetland and used these data to discuss local economic development. Initially, students claimed polarized views of environmental issues or economic development interests; however, during a multimedia session showcasing results, students communicated more informed perspectives that clearly incorporated knowledge gained from their own research. Some students were able to make recommendations for good practices involving planned economic development near the wetland

    1998-01-01

    Project financing was defined ('where a lender to a specific project has recourse only to the cash flow and assets of that project for repayment and security respectively') and its attributes were described. Project financing was said to be particularly well suited to power, pipeline, mining, telecommunications, petro-chemicals, road construction, and oil and gas projects, i.e. large infrastructure projects that are difficult to fund on-balance sheet, where the risk profile of a project does not fit the corporation's risk appetite, or where higher leverage is required. Sources of project financing were identified. The need to analyze and mitigate risks, and being aware that lenders always take a conservative view and gravitate towards the lowest common denominator, were considered the key to success in obtaining project financing funds. TransAlta Corporation's project financing experiences were used to illustrate the potential of this source of financing

    This report summarizes the hybrid electric concept design, analysis, and modeling work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, consisting of Boeing Research and Technology, Boeing Commercial Airplanes, General Electric, and Georgia Tech.Performance and sizing tasks were conducted for hybrid electric versions of a conventional tube-and-wing aircraft and a hybrid wing body. The high wing Truss Braced Wing (TBW) SUGAR Volt was updated based on results from the TBW work (documented separately) and new engine performance models. Energy cost and acoustic analyses were conducted and technology roadmaps were updated for hybrid electric and battery technology. NOx emissions were calculated for landing and takeoff (LTO) and cruise. NPSS models were developed for hybrid electric components and tested using an integrated analysis of superconducting and non-superconducting hybrid electric engines. The hybrid electric SUGAR Volt was shown to produce significant emissions and fuel burn reductions beyond those achieved by the conventionally powered SUGAR High and was able to meet the NASA goals for fuel burn. Total energy utilization was not decreased but reduced energy cost can be achieved for some scenarios. The team was not able to identify a technology development path to meet NASA's noise goals

    1994-01-01

    Increasing competition among airline manufacturers and operators has highlighted the issue of aircraft efficiency. Fewer aircraft orders have led to an all-out efficiency improvement effort among the manufacturers to maintain if not increase their share of the shrinking number of aircraft sales. Aircraft efficiency is important in airline profitability and is key if fuel prices increase from their current low. In a continuing effort to improve aircraft efficiency and develop an optimal performance technology base, NASA Dryden Flight Research Center developed and flight tested an adaptive performance seeking control system to optimize the quasi-steady-state performance of the F-15 aircraft. The demonstrated technology is equally applicable to transport aircraft although with less improvement. NASA Dryden, in transitioning this technology to transport aircraft, is specifically exploring the feasibility of applying adaptive optimal control techniques to performance optimization of redundant control effectors. A simulation evaluation of a preliminary control law optimizes wing-aileron camber for minimum net aircraft drag. Two submodes are evaluated: one to minimize fuel and the other to maximize velocity. This paper covers the status of performance optimization of the current fleet of subsonic transports. Available integrated controls technologies are reviewed to define approaches using active controls. A candidate control law for adaptive performance optimization is presented along with examples of algorithm operation.

    Fourteen foam insulation specimens were tested. Some were plain foam while others contained flame retardants, chopped fiberglass reinforcement and/or vapor barriers. The thermal performance of the insulation was determined by measuring the rate at which LH2 boiled from an aluminum tank insulated with the test material. The test specimens were approximately 50 mm (2 in.) thick. They were structurally scaled so that the test cycle would duplicate the maximum thermal stresses predicted for the thicker insulation of an aircraft liquid hydrogen fuel tank during a typical subsonic flight. The simulated flight cycle of approximately 10 minutes duration heated the other insulation surface to 316 K (110 F) and cooled it to 226 K (20 F) while the inner insulation surface remained at liquid hydrogen temperature of 20 K (-423 F). Two urethane foam insulations exceeded the initial life goal of 2400 simulated flight cycles and sustained 4400 cycles with only minor damage. The addition of fiberglass reinforcement of flame retardant materials to an insulation degraded thermal performance and/or the life of the foam material. Installation of vapor barriers enhanced the structural integrity of the material but did not improve thermal performance. All of the foams tested were available materials; none were developed specifically for LH2 service.

The critical conditions for the occurrence of chaotic motions are obtained. The chaotic features on the system parameters are discussed in detail. The conditions for subharmonic bifurcations are also obtained. For the system with no structural damping, chaotic motions can occur through infinite subharmonic bifurcations of odd orders. Furthermore, we confirm our theoretical predictions by numerical simulations. The theoretical results obtained here can help us to eliminate or suppress large nonlinear vibrations and chaotic motions of the nonlinear viscoelastic plates. Based on Melnikov method, complex dynamical behaviors of the nonlinear viscoelastic plates can be controlled by modifying the system parameters.

    Recent developments have reduced fan and jet noise contributions to overall subsonic aircraft jet-engine noise. Now, aircraft designers are turning their attention toward reducing engine core noise. The NASA Glenn Research Center and NASA Langley Research Center have teamed to investigate the development of a compact, lightweight acoustic liner based on oxide/oxide ceramic matrix composite (CMC) materials. The NASA team has built upon an existing oxide/oxide CMC sandwich structure concept that provides monotonal noise reduction. Oxide/oxide composites have good high temperature strength and oxidation resistance, which could allow them to perform as core liners at temperatures up to 1000C (1832F), and even higher depending on the selection of the composite constituents. NASA has initiated the evaluation of CMC-based liners that use cells of different lengths (variable-depth channels) or effective lengths to achieve broadband noise reduction. Reducing the overall liner thickness is also a major goal, to minimize the volume occupied by the liner. As a first step toward demonstrating the feasibility of our concepts, an oxide/oxide CMC acoustic testing article with different channel lengths was tested. Our approach, summary of test results, current status, and goals for the future are reported.

    Nonlinear evolution of disturbances in an axisymmetric, high subsonic, high Reynolds number hot jet with forced eigenmodes is studied using the Parabolized Stability Equations (PSE) approach to understand how modes interact with one another. Both frequency and azimuthal harmonic interactions are analyzed by setting up one or two modes at higher initial amplitudes and various phases. While single mode excitation leads to harmonic growth and jet noise amplification, controlling the evolution of a specific mode has been made possible by forcing two modes (m 1 , n 1 ), (m 2 , n 2 ), such that the difference in azimuth and in frequency matches the desired “target” mode (m 1 − m 2 , n 1 − n 2 ). A careful setup of the initial amplitudes and phases of the forced modes, defined as the “killer” modes, has allowed the minimizing of the initially dominant instability in the near pressure field, as well as its estimated radiated noise with a 15 dB loss. Although an increase of the overall sound pressure has been found in the range of azimuth and frequency analyzed, the present paper reveals the possibility to make the initially dominant instability ineffective acoustically using nonlinear interactions with forced eigenmodes

    A subsonic thermal spraying technique (STS) was used to make different biocomposite coatings on titanium alloys for preparing three kinds of implants: 8Ti2G, HA and 8H2B, respectively. The implants were embedded in a region of jaw of dogs whose teeth were pulled out three months previously. The dogs, in two groups, were killed 30 days and 90 days, respectively, after they were operated on. Osteointegration between the implants and host bone was investigated by x-ray, histology and the SEM technique. The results showed that the three kinds of coatings all exhibited good biocompatibility and synostosis, but their osteointegration capability showed a difference and decreased in the sequence of 8H2B, HA and 8Ti2G. The activity of coating, which promoted the reactions between implants and bone tissue, was further increased by the addition of bioglass in the 8H2B coating. Subsequently, chemical bonding was formed, and the osteointegration strength was increased. The study provided a new approach to prepare biocomposite coatings. The 8H2B implants, which formed an integral functional biocomposite coating on Ti alloys, showed a better osteointegration capability with bioactivity and pore gradient variation. A theoretical base was provided for the biocomposite coating application.

Performs calculations for different tilt angles of the jet ωj blowing and constructs the fields of velocities and pressures of the flow, jet trajectory, as well as calculates the pressure coefficients on the plate surface.To solve this problem, the CAD Solidworks Flow Simulation software was used. This package contains the solution of the Nowier-Stokes equation, which is necessary for modeling this problem.To test operation capability of the closing condition (k-th model of turbulence and proper choice of the boundaries of the computational domain, was solved a test problem forThe solution analysis has shown that the k-th model of turbulence was capable, and has a good agreement with other authors' experiment results [4]. Based on the selected conditions, further calculations were carried out for different tilt angles of jet blowing.In the course of research activities, it was revealed that the tilt angle of the jet blowing has a strong impact on redistribution of velocity and pressure in the area of the jet interaction, which allows the efficient use of such jets to control aerodynamic characteristics of the aircraft with the same power consumption for blowing out the gas. The solution of this problem is very relevant in wide application in aviation and rocket and space technology.

    1979-01-01

    The aerodynamic design of a wind-tunnel model of a wing representative of that of a subsonic jet transport aircraft, fitted with winglets, was performed using two recently developed optimal wing-design computer programs. Both potential flow codes use a vortex lattice representation of the near-field of the aerodynamic surfaces for determination of the required mean camber surfaces for minimum induced drag, and both codes use far-field induced drag minimization procedures to obtain the required spanloads. One code uses a discrete vortex wake model for this far-field drag computation, while the second uses a 2-D advanced panel wake model. Wing camber shapes for the two codes are very similar, but the resulting winglet camber shapes differ widely. Design techniques and considerations for these two wind-tunnel models are detailed, including a description of the necessary modifications of the design geometry to format it for use by a numerically controlled machine for the actual model construction.

    The Intergovernmental Panel on Climate Change estimated a peak increase in ozone ranging from 7-12 ppbv (zonal and annual average, and relative to a baseline with no aircraft), due to the subsonic aircraft in the year 2015, corresponding to aircraft emissions of 1.3 TgN/year. This range of values presumably reflects differences in model input (e.g., chemical mechanism, ground emission fluxes, and meteorological fields), and algorithms. The model implemented by the Global Modeling Initiative allows testing the impact of individual model components on the assessment calculations. We present results of the impact of doubling the 1995 aircraft emissions of NOx, corresponding to an extra 0.56 TgN/year, utilizing meteorological data from NASA's Data Assimilation Office (DAO), the Goddard Institute for Space Studies (GISS), and the Middle Atmosphere Community Climate Model, version 3 (MACCM3). Comparison of results to observations can be used to assess the model performance. Peak ozone perturbations ranging from 1.7 to 2.2 ppbv of ozone are calculated using the different fields. These correspond to increases in total tropospheric ozone ranging from 3.3 to 4.1 Tg/Os. These perturbations are consistent with the IPCC results, due to the difference in aircraft emissions. However, the range of values calculated is much smaller than in IPCC.

  10. Extension of analytical indicial aerodynamics to generic trapezoidal wings in subsonic flow

    Directory of Open Access Journals (Sweden)

    Andrea DA RONCH

    2018-04-01

    Full Text Available Analytical indicial aerodynamic functions are calculated for several trapezoidal wings in subsonic flow, with a Mach number 0.3 ≤ Ma ≤ 0.7. The formulation herein proposed extends well-known aerodynamic theories, which are limited to thin aerofoils in incompressible flow, to generic trapezoidal wing planforms. Firstly, a thorough study is executed to assess the accuracy and limitation of analytical predictions, using unsteady results from two state-of-the-art computational fluid dynamics solvers as cross-validated benchmarks. Indicial functions are calculated for a step change in the angle of attack and for a sharp-edge gust, each for four wing configurations and three Mach numbers. Then, analytical and computational indicial responses are used to predict dynamic derivatives and the maximum lift coefficient following an encounter with a one-minus-cosine gust. It is found that the analytical results are in excellent agreement with the computational results for all test cases. In particular, the deviation of the analytical results from the computational results is within the scatter or uncertainty in the data arising from using two computational fluid dynamics solvers. This indicates the usefulness of the developed analytical theories. Keywords: Analytical approach, CFD, Compressible flow, Gust response, Indicial aerodynamics, Trapezoidal wing

    1993-01-01

    This report represents a general theory applicable to axial, radial, and mixed flow turbomachines operating at subsonic and supersonic speeds with a finite number of blades of finite thickness. References reflect the evolution of computational methods used, from the inception of the theory in the 50's to the high-speed computer era of the 90's. Two kinds of relative stream surfaces, S(sub 1) and S(sub 2), are introduced for the purpose of obtaining a three-dimensional flow solution through the combination of two-dimensional flow solutions. Nonorthogonal curvilinear coordinates are used for the governing equations. Methods of computing transonic flow along S(sub 1) and S(sub 2) stream surfaces are given for special cases as well as for fully three-dimensional transonic flows. Procedures pertaining to the direct solutions and inverse solutions are presented. Information on shock wave locations and shapes needed for computations are discussed. Experimental data from a Deutsche Forschungs- und Versuchsanstalt fur Luft- und Raumfahrt e.V. (DFVLR) rotor and from a Chinese Academy of Sciences (CAS) transonic compressor rotor are compared with the computed flow properties.

    In the framework of jet noise computation, a numerical simulation of a subsonic turbulent hot jet is performed using large-eddy simulation. A geometrical tripping is used in order to trigger the turbulence at the nozzle exit. In a first part, the validity of the simulation is assessed by comparison with experimental measurements. The mean and rms velocity fields show good agreement, so do the azimuthal composition of the near pressure field and the far field spectra. Discrepancies remain close to the nozzle exit which lead to a limited overestimation of the pressure levels in both near and far fields, especially near the 90{sup ∘} angular sector. Two point correlation analyses are then applied to the data obtained from the simulation. These enable to link the downstream acoustic radiation, which is the main direction of radiation, to pressure waves developing in the shear layer and propagating toward the potential core end. The intermittency of the downstream acoustic radiation is evidenced and related to the coherent structures developing in the shear layer.

    As DOE continues to forge ahead and re-evaluate post cold war missions, facilities that were constructed and operated for DOE/DOD over the past 50+ years are coming to the end of their useful life span. These various facilities throughout the country had served a very useful purpose in our nations history; however, their time of Cold War materials production has come to an end. With this looming finalization comes a decision as to how to remedy their existence: D and R the facilities and return to ''Greenfield''; or, retrofit the existing facilities to accommodate the newer missions of the DOE Complex. The 105-K Reactor Building located at the Savannah River Site in Aiken, South Carolina was retrofit on an accelerated project schedule for a new mission called K-Area Materials Storage (KAMS). Modifications to the former defense reactor's building and equipment will allow storage of Plutonium from the Rocky Flats Site in Colorado and other materials deemed necessary by the Department of Energy. Proper project planning and activity sequencing allowed the DOE and the Westinghouse Savannah River Company to realize savings from: the recycling and/or reuse of modified facility components; reduction and reclassification of waste; reduction in radiological area footprint (rollbacks)

    Since the late 1980s, the concept of ‘ successful ageing’ has set the frame for discourse about contemporary ageing research. Through an analysis of the reception to John W. Rowe and Robert L. Kahn's launch of the concept of ‘ successful ageing’ in 1987, this article maps out the important themes...... and discussions that have emerged from the interdisciplinary field of ageing research. These include an emphasis on interdisciplinarity; the interaction between biology, psycho-social contexts and lifestyle choices; the experiences of elderly people; life-course perspectives; optimisation and prevention...... strategies; and the importance of individual, societal and scientific conceptualisations and understandings of ageing. By presenting an account of the recent historical uses, interpretations and critiques of the concept, the article unfolds the practical and normative complexities of ‘ successful ageing’....

    This study examines the determinants of citation success among authors who have recently published their work in economic history journals. Besides offering clues about how to improve one's scientific impact, our citation analysis also sheds light on the state of the field of economic history...... find similar patterns when assessing the same authors' citation success in economics journals. As a novel feature, we demonstrate that the diffusion of research — publication of working papers, as well as conference and workshop presentations — has a first-order positive impact on the citation rate........ Consistent with our expectations, we find that full professors, authors appointed at economics and history departments, and authors working in Anglo-Saxon and German countries are more likely to receive citations than other scholars. Long and co-authored articles are also a factor for citation success. We...

  17. The Peruvian Citizen Perception and Expectation toward the e-Government. The Electronic Tax Payment as a Successful e-Gov Project

    2010-05-01

    Full Text Available In this chapter, the authors try to stand out how the Latin American governments, specifically the Peruvian government, can evaluate its efforts implementing electronic administration initiatives, identifying what the citizen expects from the electronic administration and how he or she perceives it, applying an evaluation model to the electronic tax payment service implemented, as a successful initiative at Latin-America. The proposed model to achieve this, was developed by one of the authors during his doctoral dissertation (Cardona, 2004 and evaluated by the other one as dissertation judge. It includes five different independent and latent constructs, Attitude, Aptitude, Trust, Relevance and Satisfaction that affect two dependent and latent constructs, the Citizen Perception and the Citizen Expectative towards its relationship with the Public Administration through the use of Information and Communication Technologies - ICT, under the effect of illustrative variables related with citizen, institutions and context.

    A safe delivery is part of a good start in life, and a continuous focus on preventing harm during delivery is crucial, even in settings with a good safety record. In January 2013, the labour unit at Copenhagen University Hospital, Hvidovre, undertook a quality improvement (QI) project to prevent asphyxia and reduced the percentage of newborns with asphyxia by 48%. The change theory consisted of two primary elements: (1) the clinical content, including three clinical bundles of evidence-based care, a 'delivery bundle', an 'oxytocin bundle' and a 'vacuum extraction bundle'; (2) an implementation theory, including improving skills in interpretation of cardiotocography, use of QI methods and participation in a national learning network. The Model for Improvement and Deming's system of profound knowledge were used as a methodological framework. Data on compliance with the care bundles and the number of deliveries between newborns with asphyxia (Apgar statistical process control. Compliance with all three clinical care bundles improved to 95% or more, and the percentages of newborns with pH <7 and Apgar <7 after 5 min were reduced by 48% and 31%, respectively. In general, the QI approach strengthened multidisciplinary teamwork, systematised workflow and structured communication around the deliveries. Changes included making a standard memo in the medical record, the use of a bedside whiteboard, bedside handovers, shared decisions with a peer when using an oxytocin infusion and the use of a checklist before vacuum extractions. This QI project illustrates how aspects of patient safety, such as the prevention of asphyxia, can be improved using QI methods to more reliably implement best practice, even in high-performing systems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The many individual salamanders, frogs, caecilians, and their larvae encountered during the course of an inventory or monitoring project will have to be identified to species. Depending on the goals and sampling method(s) used, some individuals will be identified from a distance by their calls, others will be handled. At the same time, some will be marked for recapture, and others will be sampled as vouchers. For each, certain minimum data should be recorded. In this section, data pertaining to locality and sampling methodology are considered, information on microhabitats and specimen vouchers is covered in sections that follow. I feel strongly that the data outlined here should be the minimum for any project. Investigators with specific goals may require additional types of data as well.Standardized, printed sheets containing the required data categories provide a convenient, inexpensive, and effective way to ensure that all the desired information is recorded in a consistent format, Data sheets should be well organized, printed on good-quality paper (75%-100% cotton content) and include extra space (e.g., other side of sheet) for notes that do not fit preestablished categoriesData should be recorded in the field with permanent (waterproof) ink as simply and directly as possible. I strongly recommend against the use of data codes in the field; it is too easy to forget codes or to enter the wrong code. Original data sheets can be photocopied for security, but they should not be copied by hand. If data are to be coded for computer analysis, the original or photocopied sheets should be used for data entry to minimize transcription errors. Some workers prefer recording information on small tape recorders; this also works well if a list of the standard data categories is checked during taping to ensure that all required information is recorded. Information recorded on tapes should be transcribed to data sheets or into a computer within 24 hours of the sample.

    Full Text Available Background: Obesity in adolescence is the strongest risk factor for obesity in adulthood. This study aimed to evaluate the effects of a comprehensive lifestyle intervention on different anthropometric indices in 12–16-year-old boy adolescents after 12 Weeks of Intervention. Methods: A total of 96 male adolescents from two schools participated in this study. The schools were randomly assigned to intervention (53 students and control school (43 students. Height and weight of students were measured and their body mass index (BMI was calculated. Body fat percent (BF and body muscle percent (BM was assessed using a bioimpedance analyzer considering the age, gender, and height of students at baseline and after intervention. The obesity reduction intervention was implemented in the intervention school based on the Ottawa charter for health promotion. Results: Twelve weeks of intervention decreased BF percent in the intervention group in comparison with the control group (decreased by 1.81% in the intervention group and increased by 0.39% in the control group, P < 0.01. However, weight, BMI, and BM did not change significantly. Conclusions: The result of this study showed that a comprehensive lifestyle intervention decreased the body fat percent in obese adolescents, although these changes was not reflected in the BMI. It is possible that BMI is not a good indicator in assessment of the success of obesity management intervention.

    2003-01-01

    In the Yakima Spring Chinook supplementation program, wild fish are brought into the Cle Elum Hatchery, artificially crossed, reared, transferred to acclimation sites, and released into the upper Yakima River as smolts. When these fish mature and return to the Yakima River most of them will be allowed to spawn naturally; a few, however, will be brought back to the hatchery and used for research purposes. In order for this supplementation approach to be successful, hatchery-origin fish must be able to spawn and produce offspring under natural conditions. Recent investigations on salmonid fishes have indicated that exposure to hatchery environments during juvenile life may cause significant behavioral, physiological, and morphological changes in adult fish. These changes appear to reduce the reproductive competence of hatchery fish. In general, males are more affected than females; species with prolonged freshwater rearing periods are more strongly impacted than those with shorter rearing periods; and stocks that have been exposed to artificial culture for multiple generations are more impaired than those with a relatively short exposure history to hatchery conditions.

    Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy. Blood samples were taken at three time points: Before, four weeks after and two years after adjuvant chemotherapy. Serum AMH-levels were evaluated in a central laboratory by a quantitative immunoassay AMH Gen II ELISA (Beckman Coulter, Brea, USA). Median age was 36 years (21-40 years). Median serum AMH-level before chemotherapy was 1.37 ng/ml (range chemotherapy AMH-levels dropped in 98.6% of the patients to chemotherapy induced amenorrhea occurred only in 50.6% of the patients. In this analysis, premenopausal patients showed a high rate of ovarian impairment reflected by low AMH-levels after chemotherapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Near-peer facilitators (senior students serving as facilitators to their more junior peers) bring a unique student-based perspective to teaching. With fewer years of teaching experience however, students who become involved in a facilitator role typically develop related skills quickly through a process of trial-and-error within the classroom. The aim of this paper is to report on the authors' own experiences and reflections as student near-peer facilitators for an inquiry-based project in an undergraduate anatomy course. Three areas of the facilitator experience are explored: (1) offering adequate guidance as facilitators of inquiry, (2) motivating students to engage in the inquiry process, and (3) fostering creativity in learning. A practical framework for providing guidance to students is discussed which offers facilitators a scaffold for asking questions and assisting students through the inquiry process. Considerations for stimulating intrinsic motivations toward inquiry learning are made, paying attention to ways in which facilitators might influence feelings of motivation towards learning. Also, the role of creativity in inquiry learning is explored by highlighting the actions facilitators can take to foster a creative learning environment. Finally, recommendations are made for the development of formalized training programs that aid near-peer facilitators in the acquisition of facilitation skills before entering into a process of trial-and-error within the classroom. © 2013 American Association of Anatomists.

    Two streams in the Imnaha River subbasin (Camp Creek and Little Sheep Creek) and eight streams in the Grande Ronde River subbasin (Catherine, Deer, Five Points, Fly, Indian, Lookingglass, Meadow, and Sheep creeks) were selected as study streams to evaluate the success and impacts of steelhead supplementation in northeast Oregon. The habitat of the study streams was inventoried to compare streams and to evaluate whether habitat might influence the performance parameters we will measure in the study. The mean fecundity of hatchery and natural steelhead 1-salts returning to Little Sheep Creek fish facility in 1990 and 1991 ranged from 3,550 to 4,663 eggs/female; the mean fecundity of hatchery and natural steelhead 2-salts ranged from 5,020 to 5,879 eggs/female. Variation in length explained 57% of the variation in fecundity of natural steelhead, but only 41% to 51% of the variation in fecundity of hatchery steelhead. Adult steelhead males had an average spermatocrit of 43.9% at spawning. We were also able to stain sperm cells so that viable cells could be distinguished from dead cells. Large, red disc tags may be the most useful for observing adults on the spawning grounds. The density of wild, juvenile steelhead ranged from 0 fish/l00{sup 2} to 35.1 (age-0) and 14.0 (age-1) fish/l00m{sup 2}. Evidence provided from the National Marine Fisheries Service suggests that hatchery and wild fish within a subbasin are genetically similar. The long-term experimental design is presented as a component of this report.

    Full text: At present an active development of digital communication technologies has resulted in reduction of their cost and increase of their possibilities. As a result the remote monitoring systems gain new development. The increase of the requirements to a safety level on potentially dangerous and very important objects makes such systems extremely attractive for using in a system of national departmental or international control and inspections. Purpose of using such systems is to provide control for correctness of subject to the control-regulated procedures performance, performance of management or inspection bodies' instructions and operating of existing protection systems, at integration with them. This control is independent from object staff. The remote monitoring systems usage by supervising bodies at an object gives following advantages: timely reception of information; increase of information volume at the expense of constant non physically presence of an onsite inspector; increase of received information objectivity at the expense of the fact of 'undeclared inspections' realization; an opportunity of application modern information technologies for analysis and storage of digital information; reduction of impact on object's work; reduction of volume of physical inspections and expenses for their realization. All above was reflected in the material protect, control and accounting (MPC and A) operational monitoring (MOM) program, begun under Russian-American cooperation in the field of MPC and A in 2001. MOM program purpose is to control double application materials and radioactive divided materials, activity of the people under MPC and A program and procedures ensuring performance of guarantees on special nuclear material (SNM) protection and non-proliferation. The Moscow engineering-physics institute (state university) (MEPhl) was chosen as an object of realization of MOM system pilot project. The reasons are that MEPhl is installed under framework of

    A test was conducted in the Langley 14 by 22 Foot Subsonic Tunnel to determine the effect of the reverse-thrust flow field of a wing-mounted advanced ducted propeller on the aerodynamic characteristics of a semispan subsonic high-lift transport model. The advanced ducted propeller (ADP) model was mounted separately in position alongside the wing so that only the aerodynamic interference of the propeller and nacelle affected the aerodynamic performance of the transport model. Mach numbers ranged from 0.14 to 0.26; corresponding Reynolds numbers ranged from 2.2 to 3.9 x 10(exp 6). The reverse-thrust flow field of the ADP shielded a portion of the wing from the free-stream airflow and reduced both lift and drag. The reduction in lift and drag was a function of ADP rotational speed and free-stream velocity. Test results included ground effects data for the transport model and ADP configuration. The ground plane caused a beneficial increase in drag and an undesirable slight increase in lift. The ADP and transport model performance in ground effect was similar to performance trends observed for out of ground effect. The test results form a comprehensive data set that supports the application of the ADP engine and airplane concept on the next generation of advanced subsonic transports. Before this investigation, the engine application was predicted to have detrimental ground effect characteristics. Ground effect test measurements indicated no critical problems and were the first step in proving the viability of this engine and airplane configuration.

    2003-01-01

    This paper introduces a competitive computational approach for determining time-dependent far-field sound generated by subsonic flows around lifting airfoils. The procedure assumes the linearity of the sound field away from a bounded region surrounding the airfoil. It is assumed that the sound pressure on the boundary of this enclosed region (referred to as the Kirchhoff surface) is specified, possibly by another procedure such as solving the full Euler equations. Away from the Kirchhoff surface, the Euler equations are linearized about a uniform mean flow. It is well known that linearized Euler equations can be uncoupled into a scalar convective wave equation. However, due to the anisotropy present in the convective wave equation, it is difficult to compute solutions. In this context, direct numerical simulation of the convective wave equation requires proper numerical descriptions of far-field boundary conditions which is a non-trivial task. Moreover, if accurate far-field conditions can be formulated, the computational cost of direct simulation can be prohibitive even in a modest computational domain. In this paper, we present an alternate solution procedure. First, the problem is transformed via the Laplace transform (with appropriate initial conditions) into a reduced wave equation. The convective term in the reduced wave equation is removed using a dependent variable transformation. Then we use Gothert's rule, to obtain a Helmholtz like equation with complex wave number, which is subsequently solved using double layer potential theory. Finally upon application of numerical inverse Laplace transform techniques, far-field acoustic pressure is obtained as a function of space and time

    The 1985 ACT airplane is the Final Active Controls Technology (ACT) Airplane with the addition of three-axis fly by wire. Thus it retains all the efficiency features of the full ACT system plus the weight and cost savings accruing from deletion of the mechanical control system. The control system implements the full IAAC spectrum of active controls except flutter-mode control, judged essentially nonbeneficial, and incorporates new control surfaces called flaperons to make the most of wing-load alleviation. This redundant electronic system is conservatively designed to preserve the extreme reliability required of crucial short-period pitch augmentation, which provides more than half of the fuel savings.

    Carrying out a project as planned is not a guarantee for success. Projects may fail because project management does not take the requirements, wishes and concerns of stakeholders sufficiently into account. Projects can only be successful though contributions from stakeholders. And in the end, it is the stakeholders that evaluate whether they find that the project is a success. To manage stakeholders effectively, you need to know your stakeholders, their behaviours and attitudes towards the project. In Project Stakeholder Management, the authors give guidance on how to adopt an analytical and s

    A new aeroacoustic measurement capability has been developed for use in open-jet testing in the NASA Langley 14- by 22-Foot Subsonic Tunnel (14x22 tunnel). A suite of instruments has been developed to characterize noise source strengths, locations, and directivity for both semi-span and full-span test articles in the facility. The primary instrument of the suite is a fully traversable microphone phased array for identification of noise source locations and strengths on models. The array can be mounted in the ceiling or on either side of the facility test section to accommodate various test article configurations. Complementing the phased array is an ensemble of streamwise traversing microphones that can be placed around the test section at defined locations to conduct noise source directivity studies along both flyover and sideline axes. A customized data acquisition system has been developed for the instrumentation suite that allows for command and control of all aspects of the array and microphone hardware, and is coupled with a comprehensive data reduction system to generate information in near real time. This information includes such items as time histories and spectral data for individual microphones and groups of microphones, contour presentations of noise source locations and strengths, and hemispherical directivity data. The data acquisition system integrates with the 14x22 tunnel data system to allow real time capture of facility parameters during acquisition of microphone data. The design of the phased array system has been vetted via a theoretical performance analysis based on conventional monopole beamforming and DAMAS deconvolution. The performance analysis provides the ability to compute figures of merit for the array as well as characterize factors such as beamwidths, sidelobe levels, and source discrimination for the types of noise sources anticipated in the 14x22 tunnel. The full paper will summarize in detail the design of the instrumentation

    An important goal for modern fluid mechanics experiments is to provide datasets which present a challenge for Computational Fluid Dynamics simulations to reproduce. Such "CFD validation experiments" should be well-characterized and well-documented, and should investigate flows which are difficult for CFD to calculate. It is also often convenient for the experiment to be challenging for CFD in some aspects while simple in others. This report is part of the continuing documentation of a series of experiments conducted to characterize the flow around an axisymmetric, modified-cosine-shaped, wall-mounted hill named "FAITH" (Fundamental Aero Investigates The Hill). Computation of this flow is easy in some ways - subsonic flow over a simple shape - while being complex in others - separated flow and boundary layer interactions. The primary set of experiments were performed on a 15.2 cm high, 45.7 cm base diameter machined aluminum model that was tested at mean speeds of 50 m/s (Reynolds Number based on height = 500,000). The ratio of model height to boundary later height was approximately 3. The flow was characterized using surface oil flow visualization, Cobra probe to determine point-wise steady and unsteady 3D velocities, Particle Image Velocimetry (PIV) to determine 3D velocities and turbulence statistics along specified planes, Pressure Sensitive Paint (PSP) to determine mean surface pressures, and Fringe Imaging Skin Friction (FISF) to determine surface skin friction magnitude and direction. A set of pathfinder experiments were also performed in a water channel on a smaller scale (5.1 cm high, 15.2 cm base diameter) sintered nylon model. The water channel test was conducted at a mean test section speed of 3 cm/s (Reynolds Number of 1500), but at the same ratio of model height to boundary layer thickness. Dye injection from both the model and an upstream rake was used to visualize the flow. This report summarizes the experimental set-up, techniques used, and data

    We have carried out a numerical study of the influence of the upstream Mach number on the flutter of a two-dimensional, cantilevered, flexible plate subject to a subsonic, inviscid, open flow. We have assumed a linear elastic model for the plate and that the fluid flow is governed by the linearized potential theory. The fluid equations are solved with a novel frequency-domain, finite differences method to obtain the generalized aerodynamic forces as a function of the plate displacements. Then, these generalized forces are coupled to the equation of motion of the plate and an eigenvalue analysis is performed to find the flutter point. The obtained results are in good agreement with those of related theoretical and experimental studies found in the literature. To the best of our knowledge, the analysis performed here is the first self-consistent, parametric study of the influence of the compressibility on the flutter point of a two-dimensional cantilevered plate in subsonic flow.

  3. Wind tunnel investigation of the interaction and breakdown characteristics of slender wing vortices at subsonic, transonic, and supersonic speeds

    The vortex dominated aerodynamic characteristics of a generic 65 degree cropped delta wing model were studied in a wind tunnel at subsonic through supersonic speeds. The lee-side flow fields over the wing-alone configuration and the wing with leading edge extension (LEX) added were observed at M (infinity) equals 0.40 to 1.60 using a laser vapor screen technique. These results were correlated with surface streamline patterns, upper surface static pressure distributions, and six-component forces and moments. The wing-alone exhibited vortex breakdown and asymmetry of the breakdown location at the subsonic and transonic speeds. An earlier onset of vortex breakdown over the wing occurred at transonic speeds due to the interaction of the leading edge vortex with the normal shock wave. The development of a shock wave between the vortex and wing surface caused an early separation of the secondary boundary layer. With the LEX installed, wing vortex breakdown asymmetry did not occur up to the maximum angle of attack in the present test of 24 degrees. The favorable interaction of the LEX vortex with the wing flow field reduced the effects of shock waves on the wing primary and secondary vortical flows. The direct interaction of the wing and LEX vortex cores diminished with increasing Mach number. The maximum attainable vortex-induced pressure signatures were constrained by the vacuum pressure limit at the transonic and supersonic speeds.

    Full Text Available The emerging concept of successful aging is based on evidence that in healthy individual when they get aged, there are  considerable variations in physiological functions alteration. Some people exhibiting greater, but others very few or no age related alteration. The first is called poor aging and the later is called successful pattern of aging (Lambert SW, 2008. Thus, in the simple words the successful aging concept is define as an opportunity of old people to stay  active and productive condition despite they get aged chronologically. Aging itself might be defined as the progressive accumulation of changes with time associated with or responsible for the ever-increasing susceptibility to disease and death which accompanies advancing age (Harman D, 1981. The time needed to accumulate changes is attributable to aging process. The marked emerging questions are how does aging happen and where does aging start? To answer these questions and because of the complexity of aging process, there are more than 300 aging theories have been proposed to explain how and where aging occured and started respectively. There are too many to enumerate theories and classification of aging process. In summary, all of these aging theories can be grouped into three clusters: 1. Genetics program theory, this theory suggests that aging is resulted from program directed by the genes; 2. Epigenetic theory, in these theory aging is resulted from environmental random events not determined by the genes; 3. Evolutionary theory, which propose that aging is a medium for disposal mortal soma in order to avoid competition between organism and their progeny for food and space, did not try to explain how aging occur, but possibly answer why aging occur (De la Fuente. 2009. Among the three groups of aging theories, the epigenetic theory is useful to explain and try to solve the enigma of aging which is prominently caused by internal and external environmental influences

  8. Population success.

    Science.gov (United States)

    1982-01-01

    "The commitment to population programs is now widespread," says Rafael Salas, Executive Director of the UNFPA, in its report "State of World Population." About 80% of the total population of the developing world live in countries which consider their fertility levels too high and would like them reduced. An important impetus came from the World Conference of 1974. The Plan of Action from the conference projected population growth rates in developing countries of 2.0% by 1985. Today it looks as though this projection will be realized. While in 1969, for example, only 26 developing countries had programs aimed at lowering or maintaining fertility levels, by 1980 there were 59. The International Population Conference, recently announced by the UN for 1984, will, it is hoped, help sustain that momentum. Cuba is the country which has shown the greatest decline in birth rate so far. The birth rate fell 47% between 1965-1970 and 1975-1980. Next came China with a 34% decline in the same period. After these came a group of countries--each with populations of over 10 million--with declines of between 15 and 25%: Chile, Colombia, India, Indonesia, the Republic of Korea, Malaysia and Thailand. Though birth rates have been dropping significantly the decline in mortality rates over recent years has been less than was hoped for. The 1974 conference set 74 years as the target for the world's average expectation of life, to be reached by the year 2000. But the UN now predicts that the developing countries will have only reached 63 or 64 years by then. High infant and child mortality rates, particularly in Africa, are among the major causes. The report identifies the status of women as an important determinant of family size. Evidence from the UNFPA-sponsored World Fertility Survey shows that in general the fertility of women decreases as their income increases. It also indicates that women who have been educated and who work outside the home are likely to have smaller families

  10. Development of Multi-perspective Diagnostics and Analysis Algorithms with Applications to Subsonic and Supersonic Combustors

    Wickersham, Andrew Joseph

    : Fourier analysis, proper orthogonal decomposition (POD), and wavelet analysis (WA). These algorithms were first demonstrated and tested on imaging measurements obtained from one perspective in a sub-sonic combustor (up to Mach 0.2). The results show that these algorithms are effective in extracting the key physics from large datasets, including the characteristic frequencies of flow-flame interactions especially during transient processes such as lean blow off and ignition. After these relatively simple tests and demonstrations, these algorithms were applied to process the measurements obtained from multi-perspective in the supersonic combustor. compared to past analyses (which have been limited to data obtained from one perspective only), the availability of data at multiple perspective provide further insights into the flame and flow structures in high speed flows. In summary, this work shows that high speed chemiluminescence is a simple yet powerful combustion diagnostic. Especially when combined with FBEs and the analyses algorithms described in this work, such diagnostics provide full-field imaging at high repetition rate in challenging flows. Based on such measurements, a wealth of information can be obtained from proper analysis algorithms, including characteristic frequency, dominating flame modes, and even multi-dimensional flame and flow structures.

  12. Photon Doppler Velocimeter to Measure Entrained Additive Manufactured Bulk Metal Powders in Hot Subsonic and Supersonic Oxygen Gas

    Science.gov (United States)

    Tylka, Jonathan

    2016-01-01

    Parts produced by additive manufacturing, particularly selective laser melting (SLM), have been shown to silt metal particulate even after undergoing stringent precision aerospace cleaning processes (Lowrey 2016). As printed parts are used in oxygen systems with increased pressures, temperatures, and gas velocity, the risk of ignition by particle impact, the most common direct ignition source of metals in oxygen, substantially increases. The White Sands Test Facility (WSTF), in collaboration with Marshall Space Flight Center (MSFC), desires to test the ignitability of SLM metals by particle impact in heated oxygen. The existing test systems rely on gas velocity calculations to infer particle velocity in both subsonic and supersonic particle impact systems. Until now, it was not possible to directly measure particle velocity. To increase the fidelity of planned SLM ignition studies, it is necessary to validate that the Photon Doppler Velocimetry(PDV) test system can accurately measure particle velocity.

    1989-01-01

    Slender wing vortex flows at subsonic, transonic, and supersonic speeds were investigated in a 6 x 6 ft wind tunnel. Test data obtained include off-body and surface flow visualizations, wing upper surface static pressure distributions, and six-component forces and moments. The results reveal the transition from the low-speed classical vortex regime to the transonic regime, beginning at a freestream Mach number of 0.60, where vortices coexist with shock waves. It is shown that the onset of core breakdown and the progression of core breakdown with the angle of attack were sensitive to the Mach number, and that the shock effects at transonic speeds were reduced by the interaction of the wing and the lead-edge extension (LEX) vortices. The vortex strengths and direct interaction of the wing and LEX cores (cores wrapping around each other) were found to diminish at transonic and supersonic speeds.

    Longitudinal performance comparisons between flight derived and predicted values are presented for the first five NASA Space Shuttle Columbia flights. Though subsonic comparisons are emphasized, comparisons during the transonic and low supersonic regions of flight are included. Computed air data information based on the remotely sensed atmospheric measurements as well as in situ Orbiter Air Data System (ADS) measurements were incorporated. Each air data source provides for comparisons versus the predicted values from the LaRC data base. Principally, L/D, C sub L, and C sub D, comparisons are presented, though some pitching moment results are included. Similarities in flight conditions and spacecraft configuration during the first five flights are discussed. Contributions from the various elements of the data base are presented and the overall differences observed between the flight and predicted values are discussed in terms of expected variations. A discussion on potential data base updates is presented based on the results from the five flights to date.

This article describes and assesses the planning, performance, and outcome of this initiative, branded ORCID @ CMU. Design and Methods: The article chronicles why and how ORCID was integrated at CMU, including the rationale for changes in strategic plans. It assesses researcher participation in the project using transaction log and content analyses, and the performance of the ORCID project team using recommendations in the Jisc ORCID project report, frankly reporting the team’s successes and failures. The article concludes with lessons learned that should inform ORCID integration projects and expectations at other institutions. Results: The ORCID @ CMU web application was a great success. However, the project team did not allow enough time to prepare or devote enough attention to advocacy. The marketing message was not sufficiently persuasive and the marketing channels were not particularly effective. The overall participation rate in ORCID @ CMU was far below the target of 40%, though participation in many demographics exceeded the goal. Conclusions: Strategic planning does not guarantee success. Secure more than lip service from senior administrators. Recruit champions from across the institution. Develop a message that resonates with researchers. Allow sufficient time to prepare. Empower the project manager. Start with the low hanging fruit. Develop special outreach to doctoral students and postdocs.

  16. Computational Fluid Dynamic Simulation (CFD and Experimental Study on Wing-external Store Aerodynamic Interference of a Subsonic Fighter Aircraft

    2003-01-01

    Full Text Available The main objective of the present work is to study the effect of an external store on a subsonic fighter aircraft. Generally most modern fighter aircrafts are designed with an external store installation. In this study, a subsonic fighter aircraft model has been manufactured using a computer numerical control machine for the purpose of studying the effect of the aerodynamic interference of the external store on the flow around the aircraft wing. A computational fluid dynamic (CFD simulation was also carried out on the same configuration. Both the CFD and the wind tunnel testing were carried out at a Reynolds number 1.86×105 to ensure that the aerodynamic characteristic can certify that the aircraft will not be face any difficulties in its stability and controllability. Both the experiments and the simulation were carried out at the same Reynolds number in order to verify each other. In the CFD simulation, a commercial CFD code was used to simulate the interference and aerodynamic characteristics of the model. Subsequently, the model together with an external store was tested in a low speed wind tunnel with a test section sized 0.45 m×0.45 m. Measured and computed results for the two-dimensional pressure distribution were satisfactorily comparable. There is only a 19% deviation between pressure distribution measured in wind tunnel testing and the result predicted by the CFD. The result shows that the effect of the external storage is only significant on the lower surface of the wing and almost negligible on the upper surface of the wing. Aerodynamic interference due to the external store was most evident on the lower surface of the wing and almost negligible on the upper surface at a low angle of attack. In addition, the area of influence on the wing surface by the store interference increased as the airspeed increased.

    Full Text Available Business Intelligence can bring critical capabilities to an organization, but the implementation of such capabilities is often plagued with problems. Why is it that certain projects fail, while others succeed? The aim of this article is to identify the factors that are present in successful Business Intelligence projects and to organize them into a framework of critical success factors. A survey was conducted during the spring of 2011 to collect primary data on Business Intelligence projects. Findings confirm that Business Intelligence projects are wrestling with both technological and non-technological problems, but the non-technological problems are found to be harder to solve as well as more time consuming than their counterparts. The study also shows that critical success factors for Business Intelligence projects are different from success factors for Information Systems projects in general. Business Intelligences projects have critical success factors that are unique to the subject matter. Major differences can be found primarily among non-technological factors, such as the presence of a specific business need and a clear vision to guide the project. Success depends on types of project funding, the business value provided by each iteration in the project and the alignment of the project to a strategic vision for Business Intelligence at large. Furthermore, the study provides a framework for critical success factors that, explains sixty-one percent of variability of success for projects. Areas which should be given special attention include making sure that the Business Intelligence solution is built with the end users in mind, that the Business Intelligence solution is closely tied to the company’s strategic vision and that the project is properly scoped and prioritized to concentrate on the best opportunities first.

    The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and the fluid pressure was 34 MPa. The southern tip of the Reykjanes peninsula is the landward extension of the Mid-Atlantic Ridge in Iceland. Reykjanes is unique among Icelandic geothermal systems in that it is recharged by seawater, which has a critical point of 406 °C at 29.8 MPa. The geologic setting and fluid characteristics at Reykjanes provide a geochemical analog that allows us to investigate the roots of a mid-ocean ridge submarine black smoker hydrothermal system. Drilling began with deepening an existing 2.5 km deep vertical production well (RN-15) to 3 km depth, followed by inclined drilling directed towards the main upflow zone of the system, for a total slant depth of 4659 m ( ˜ 4.5 km vertical depth). Total circulation losses of drilling fluid were encountered below 2.5 km, which could not be cured using lost circulation blocking materials or multiple cement jobs. Accordingly, drilling continued to the total depth without return of drill cuttings. Thirteen spot coring attempts were made below 3 km depth. Rocks in the cores are basalts and dolerites with alteration ranging from upper greenschist facies to amphibolite facies, suggesting that formation temperatures at depth exceed 450 °C. High-permeability circulation-fluid loss zones (feed points or feed zones) were detected at multiple depth levels below 3 km depth to bottom. The largest circulation losses (most permeable zones) occurred between the bottom of the casing and 3.4 km depth. Permeable zones encountered below 3.4 km accepted less than 5 % of the injected water. Currently, the project is attempting soft stimulation to increase deep permeability. While it is too early to speculate on the energy potential of this well and its economics, the IDDP

    A 1/4-scale wind tunnel model of an airplane configuration developed for short duration flight at subsonic speeds in the Martian atmosphere has been tested in the Langley Research Center Transonic Dynamics Tunnel. The tunnel was pumped down to extremely low pressures to represent Martian Mach/Reynolds number conditions. Aerodynamic data were obtained and upper and lower surface wind pressures were measured at one spanwise station on some configurations. Three unswept wings of the same planform but different airfoil sections were tested. Horizontal tail incidence was varied as was the deflection of plain and split trailing-edge flaps. One unswept wing configuration was tested with the lower part of the fuselage removed and the vertical/horizontal tail assembly inverted and mounted from beneath the fuselage. A sweptback wing was also tested. Tests were conducted at Mach numbers from 0.50 to 0.90. Wing chord Reynolds number was varied from 40,000 to 100,000 and angles of attack and sideslip were varied from -10deg to 20deg and -10deg to 10deg, respectively.

    An experimental investigation of a series of four convergent-divergent exhaust nozzles was conducted in the Lewis 8-by-6 foot supersonic wind tunnel at Mach numbers of 0.1, 0.6, 1.6, and 2.0 over a range of nozzle pressure ratios. The thrust characteristics of these nozzles were determined by a pressure-integration technique. From a thrust standpoint, a nozzle designed to give uniform parallel flow at the exit had no advantage over the simple geometric design with conical convergent and divergent sections. The rapid-divergent nozzles might be competitive with the more gradual-divergent nozzles since the relatively short length of these nozzles would be advantageous from a weight standpoint and might result in smaller thrust losses due to friction. The thrusts, with friction losses neglected, were predicted satisfactorily by one-dimensional theory for the nozzles with relatively gradual divergence. The thrusts of the rapid-divergent designs were several percentages below the theoretical values at the design pressure ratio or above, while at low pressure ratios there was a considerable effect of free-stream Mach number, with thrusts considerably above theoretical values at subsonic speeds and somewhat above theoretical values at supersonic speeds. This Mach numb effect appeared to be related to the variation of the model base pressure with free-stream Mach number.

    Experimental data have shown that combustor temperature non-uniformities can lead to the excessive heating of first-stage rotor blades in turbines. This heating of the rotor blades can lead to thermal fatigue and degrade turbine performance. The results of recent studies have shown that variations in the circumferential location (clocking) of the hot streak relative to the first-stage vane airfoils can be used to minimize the adverse effects of the hot streak. The effects of the hot streak/airfoil count ratio on the heating patterns of turbine airfoils have also been evaluated. In the present investigation, three-dimensional unsteady Navier-Stokes simulations have been performed for a single-stage high-pressure turbine operating in high subsonic flow. In addition to a simulation of the baseline turbine, simulations have been performed for circular and elliptical hot streaks of varying sizes in an effort to represent different combustor designs. The predicted results for the baseline simulation show good agreement with the available experimental data. The results of the hot streak simulations indicate: that a) elliptical hot streaks mix more rapidly than circular hot streaks, b) for small hot streak surface area the average rotor temperature is not a strong function of hot streak temperature ratio or shape, and c) hot streaks with larger surface area interact with the secondary flows at the rotor hub endwall, generating an additional high temperature region.

    The scattering of sound at a sudden area expansion in a duct with subsonic mean flow has been modelled with a multimodal method. Technological applications are for instance internal combustion engine exhaust silencers and silencers in industrial duct systems. Both two-dimensional (2D) rectangular and 2D cylindrical geometry and uniform mean flow as well as non-uniform mean flow profiles are considered. Model results for the scattering of plane waves in case of uniform flow, in which case an infinitely thin shear layer is formed downstream of the area expansion, are compared to results obtained by other models in literature. Generally good agreement is found. Furthermore, model results for the scattering are compared to experimental data found in literature. Also here fairly good correspondence is observed. When employing a turbulent pipe flow profile in the model, instead of a uniform flow profile, the prediction for the downstream transmission- and upstream reflection coefficient is improved. However, worse agreement is observed for the upstream transmission and downstream reflection coefficient. On the contrary, employing a non-uniform jet flow profile, which represents a typical shear layer flow downstream of the expansion, gives worse agreement for the downstream transmission- and the upstream reflection coefficient, whereas prediction for the upstream transmission and downstream reflection coefficient improves.

    Boundary layer separation is detrimental to the lift and drag of most aeronautical applications. Many vortex generators (VG), both passive and active have been designed to reduce these drawbacks. This study targets to investigate the effectiveness of hybrid micro-VGs, which combine both active and passive micro-VGs in controlling separation under subsonic conditions. NACA 4415 airfoils installed with passive, active and hybrid micro-VGs each are designed, 3D printed, and tested in a wind tunnel at 26.19 m/s under Re = 2.5x105. The lift and drag measurements from a 3-component force balance prove that hybrid micro-VGs increase lift by up to 21.2%, increase drag by more than 11.3% and improve lift-to-drag ratio by at least 8.6% until up to 33.7%. From this research, it is believed that hybrid micro-VGs are competitive to the performance of active VGs and a better configuration is to be considered to reduce parasitic drag and outstand active VGs.

    Full Text Available The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and the fluid pressure was 34 MPa. The southern tip of the Reykjanes peninsula is the landward extension of the Mid-Atlantic Ridge in Iceland. Reykjanes is unique among Icelandic geothermal systems in that it is recharged by seawater, which has a critical point of 406 °C at 29.8 MPa. The geologic setting and fluid characteristics at Reykjanes provide a geochemical analog that allows us to investigate the roots of a mid-ocean ridge submarine black smoker hydrothermal system. Drilling began with deepening an existing 2.5 km deep vertical production well (RN-15 to 3 km depth, followed by inclined drilling directed towards the main upflow zone of the system, for a total slant depth of 4659 m ( ∼  4.5 km vertical depth. Total circulation losses of drilling fluid were encountered below 2.5 km, which could not be cured using lost circulation blocking materials or multiple cement jobs. Accordingly, drilling continued to the total depth without return of drill cuttings. Thirteen spot coring attempts were made below 3 km depth. Rocks in the cores are basalts and dolerites with alteration ranging from upper greenschist facies to amphibolite facies, suggesting that formation temperatures at depth exceed 450 °C. High-permeability circulation-fluid loss zones (feed points or feed zones were detected at multiple depth levels below 3 km depth to bottom. The largest circulation losses (most permeable zones occurred between the bottom of the casing and 3.4 km depth. Permeable zones encountered below 3.4 km accepted less than 5 % of the injected water. Currently, the project is attempting soft stimulation to increase deep permeability. While it is too early to speculate on the

  1. An efficient finite differences method for the computation of compressible, subsonic, unsteady flows past airfoils and panels

    Science.gov (United States)

    Colera, Manuel; Pérez-Saborid, Miguel

    2017-09-01

    A finite differences scheme is proposed in this work to compute in the time domain the compressible, subsonic, unsteady flow past an aerodynamic airfoil using the linearized potential theory. It improves and extends the original method proposed in this journal by Hariharan, Ping and Scott [1] by considering: (i) a non-uniform mesh, (ii) an implicit time integration algorithm, (iii) a vectorized implementation and (iv) the coupled airfoil dynamics and fluid dynamic loads. First, we have formulated the method for cases in which the airfoil motion is given. The scheme has been tested on well known problems in unsteady aerodynamics -such as the response to a sudden change of the angle of attack and to a harmonic motion of the airfoil- and has been proved to be more accurate and efficient than other finite differences and vortex-lattice methods found in the literature. Secondly, we have coupled our method to the equations governing the airfoil dynamics in order to numerically solve problems where the airfoil motion is unknown a priori as happens, for example, in the cases of the flutter and the divergence of a typical section of a wing or of a flexible panel. Apparently, this is the first self-consistent and easy-to-implement numerical analysis in the time domain of the compressible, linearized coupled dynamics of the (generally flexible) airfoil-fluid system carried out in the literature. The results for the particular case of a rigid airfoil show excellent agreement with those reported by other authors, whereas those obtained for the case of a cantilevered flexible airfoil in compressible flow seem to be original or, at least, not well-known.

  2. Strategies for successful software development risk management

    Full Text Available Nowadays, software is becoming a major part of enterprise business. Software development is activity connected with advanced technology and high level of knowledge. Risks on software development projects must be successfully mitigated to produce successful software systems. Lack of a defined approach to risk management is one of the common causes for project failures. To improve project chances for success, this work investigates common risk impact areas to perceive a foundation that can be used to define a common approach to software risk management. Based on typical risk impact areas on software development projects, we propose three risk management strategies suitable for a broad area of enterprises and software development projects with different amounts of connected risks. Proposed strategies define activities that should be performed for successful risk management, the one that will enable software development projects to perceive risks as soon as possible and to solve problems connected with risk materialization. We also propose a risk-based approach to software development planning and risk management as attempts to address and retire the highest impact risks as early as possible in the development process. Proposed strategies should improve risk management on software development projects and help create a successful software solution.

    Full Text Available The complexity of sustainable development and societal transitions require both analytical understandings of how coupled human-environment systems function and transdisciplinary science-to-practice approaches. The academic discourse has advanced in developing a framework for defining success in transdisciplinary research (TDR. Further empirical evidence is needed to validate the proposed concepts with TDR case studies. This paper applies a widely used TDR framework to test and critically evaluate its design principles and criteria of success with five TDR case studies the author is intimately familiar with. Overall, the design principles of the framework are validated for the five cases. Additional design principles are derived from the case analysis and proposed to complement the applied framework: (1 A project origin from society as opposed to with and for society; (2 Quickly available initiation funding; (3 Flexibility in time, objectives and methods throughout the research process; (4 Acceptance of process vs. project results; (5 Inclusion of public science communication; and (6 A demand-driven transition to a prolonged or new project partnership. The complementing principles are proposed for integration in the applied framework and are subject to further empirical testing. The reflexive empirical approach I have taken in this paper offers a key step towards removing institutional barriers for successful TDR, demonstrating how conceptual frameworks can be applied.

    2014-07-01

    Full Text Available This study describes a government–academia–industry joint training project that produces Vietnamese midlevel technical managers. To ensure collaboration success, a proactive assessment methodology was developed as a supplement to the conventional project management practices. In the postproject feedback, the funding agencies acknowledged that the project fulfilled its contractual obligations and achieved its objectives. The implementing university was pleased as it broke ground in this type of collaboration in Taiwan. The industrial partners, however, were not so sure about the effectiveness of this collaborative training endeavor because there were many skirmishes between company supervisors and Vietnamese interns caused by the interns’ self-interested perception and expectation. Consequently, a theoretical framework for predicting internship acceptance and preventing unfavorable perceptions was proposed to strengthen the proactive assessment methodology. Collaboration research, funding agencies, academia, and industry could all benefit from this study.

    The results of a comparative study using the unsteady aerodynamic lifting surface theory, known as the Doublet Lattice method, and experimental subsonic steady- and unsteady-pressure measurements, are presented for a high-aspect-ratio supercritical wing model. Comparisons of pressure distributions due to wing angle of attack and control-surface deflections were made. In general, good correlation existed between experimental and theoretical data over most of the wing planform. The more significant deviations found between experimental and theoretical data were in the vicinity of control surfaces for both static and oscillatory control-surface deflections.

    Poort, Eltjo R.; Pramono, Agung; Perdeck, Michiel; Clerc, Viktor; van Vliet, Hans

    This chapter presents the analysis and key findings of a survey on architectural knowledge sharing. The responses of 97 architects working in the Dutch IT Industry were analyzed by correlating practices and challenges with project size and success. Impact mechanisms between project size, project success, and architectural knowledge sharing practices and challenges were deduced based on reasoning, experience and literature. We find that architects run into numerous and diverse challenges sharing architectural knowledge, but that the only challenges that have a significant impact are the emotional challenges related to interpersonal relationships. Thus, architects should be careful when dealing with emotions in knowledge sharing.

  16. The prediction of noise and installation effects of high-subsonic dual-stream jets in flight

    Science.gov (United States)

    Saxena, Swati

    Both military and civil aircraft in service generate high levels of noise. One of the major contributors to this noise generated from the aircraft is the jet engine exhaust. This makes the study of jet noise and methods to reduce jet noise an active research area with the aim of designing quieter military and commercial aircraft. The current stringent aircraft noise regulations imposed by the Federal Aviation Administration (FAA) and other international agencies, have further raised the need to perform accurate jet noise calculations for more reliable estimation of the jet noise sources. The main aim of the present research is to perform jet noise simulations of single and dual-stream jets with engineering accuracy and assess forward flight effects on the jet noise. Installation effects such as caused by the pylon are also studied using a simplified pylon nozzle configuration. Due to advances in computational power, it has become possible to perform turbulent flow simulations of high speed jets, which leads to more accurate noise predictions. In the present research, a hybrid unsteady RANS-LES parallel multi-block structured grid solver called EAGLEJet is written to perform the nozzle flow calculations. The far-field noise calculation is performed using solutions to the Ffowcs Williams and Hawkings equation. The present calculations use meshes with 5 to 11 million grid points and require about three weeks of computing time with about 100 processors. A baseline single stream convergent nozzle and a dual-stream coaxial convergent nozzle are used for the flow and noise analysis. Calculations for the convergent nozzle are performed at a high subsonic jet Mach number of Mj = 0.9, which is similar to the operating conditions for commercial aircraft engines. A parallel flow gives the flight effect, which is simulated with a co-flow Mach number, Mcf varying from 0.0 to 0.28.

    Organizations that follow the principles of good Earned Value Management (EVM) create an environment that allows teams to successfully operate and thrive ? even in the face of challenges that could negatively impact their projects. Earned Value Project Management (EVPM) is a methodology used to measure and communicate the real physical progress of a project taking into account the work completed, the time taken and the costs incurred to complete that work. As a result, EVPM allows more educated and effective management decision-making, which helps evaluate and control project risk by measuring project progress in monetary terms. In the first two editions of Earned Value Project Management, Quentin W. Fleming and Joel M. Koppelman provided guidance for project management practitioners already familiar with EVPM, was well as those who were new to the use of this technique. The third edition expanded the information available on of EVPM for medium and smaller projects while still being relevant for larger projec...

    Achieving success in enterprise systems (ES) implementations is challenging. The success rate is not high in view of the sums invested by many organizations in these companywide systems. The literature is charged with reasons for unsuccessful implementations, such as a lack of top management...... support and insufficient change management. Contrary to this research, empirical data from an ES re-implementation in a Scandinavian high-tech company shows successful implementation despite many problematic shifts in outsourcing partners. Therefore, it is natural to ask: why was the re......-implementation of the ES at SCANDI successful despite the major troubles encountered during the project? Building an analysis based on ten Critical Success Factors (CSFs) combined with an investigation into the institutional structures at play, we present several reasons for the successful implementation.

    In September of 2003, twenty-nine hatchery and twenty-eight wild spring chinook adults were placed into the observation stream located at the Cle Elum Supplementation Research Facility. In, addition 20 precocious males, 7 hatchery and 13 wild, were simultaneously released into the structure. As in previous years, the fish had small amounts of fin material removed prior to being introduced into the stream so that microsatellite DNA based pedigree analyses could be performed on their subsequent progeny. The entire 127 m long by 7.9 m wide stream was made available to this group of fish. Continuous behavioral observations were made while the females prepared nests and spawned. Moreover, standard measurements of adult longevity, spawning participation, water velocity, redd sizes, gravel composition, water temperature and flow were taken. Fry produced from these fish started to emigrate from the stream in early January 2004. They were trapped and sub-sampled for later microsatellite DNA analyses. In mid May of 2004 fry emergence from the channel was complete and residual fish were captured by seine and electro-fishing so that the entire juvenile population could be proportionately sampled. Audiotape records of the behavior of wild and hatchery adults spawning in the observation stream in 2001 were transcribed into continuous ethograms. Courting, agonistic, and location data were extracted from these chronological records and analyzed to characterize the reproductive behavior of both hatchery and wild fish. In addition, a ''gold standard'' pedigree analysis was completed on the fry originating from the adults placed into the observation stream in 2001. Behavioral and morphological data collected on hatchery and wild males were linked to the results of the pedigree analysis to ascertain what factors affected their reproductive success (RS) or capacity to produce fry. Individual RS values were calculated for each male placed into the observation stream

There are also suggested some indicators which can be used to develop the incubator tasks. Once it has been defined the topic about incubation in the country, it is provided information about the items determining the company performance within an incubator. In order to do this, it is shown the way the Instituto Nacional de Investigaciones Nucleares can provide not only its facilities but also qualified personnel working for them. Thus it is given a scheme along with a brief organization description and key personnel for the incubator, stating the functions and responsibilities per each one of the persons who are part of the project direction and leading. The bases for the incubator are stated, as well as the requirements to start-up a company being supported by a company incubator. The key points to have a succesful development for the incubator are: the service it can give as well as the guidelines for companies entrance, which are classified into two sorts of customers, external and internal. It is also included a market research about the main product derived from creating a company incubator, as well as the sub-products, the market area, this is directed to the people who will benefit from it, the supply and demand involved with ININ. The main tool used was Business Plan, which defines its importance within the organization and activities guide, it is also included the Business Plan structure

  3. Underestimation of Project Costs

    Large projects almost always exceed their budgets. Estimating cost is difficult and estimated costs are usually too low. Three different reasons are suggested: bad luck, overoptimism, and deliberate underestimation. Project management can usually point to project difficulty and complexity, technical uncertainty, stakeholder conflicts, scope changes, unforeseen events, and other not really unpredictable bad luck. Project planning is usually over-optimistic, so the likelihood and impact of bad luck is systematically underestimated. Project plans reflect optimism and hope for success in a supposedly unique new effort rather than rational expectations based on historical data. Past project problems are claimed to be irrelevant because "This time it's different." Some bad luck is inevitable and reasonable optimism is understandable, but deliberate deception must be condemned. In a competitive environment, project planners and advocates often deliberately underestimate costs to help gain project approval and funding. Project benefits, cost savings, and probability of success are exaggerated and key risks ignored. Project advocates have incentives to distort information and conceal difficulties from project approvers. One naively suggested cure is more openness, honesty, and group adherence to shared overall goals. A more realistic alternative is threatening overrun projects with cancellation. Neither approach seems to solve the problem. A better method to avoid the delusions of over-optimism and the deceptions of biased advocacy is to base the project cost estimate on the actual costs of a large group of similar projects. Over optimism and deception can continue beyond the planning phase and into project execution. Hard milestones based on verified tests and demonstrations can provide a reality check.

    An active controls technology (ACT) system architecture was selected based on current technology system elements and optimal control theory was evaluated for use in analyzing and synthesizing ACT multiple control laws. The system selected employs three redundant computers to implement all of the ACT functions, four redundant smaller computers to implement the crucial pitch-augmented stability function, and a separate maintenance and display computer. The reliability objective of probability of crucial function failure of less than 1 x 10 to the -9th power per flight of 1 hr can be met with current technology system components, if the software is assumed fault free and coverage approaching 1.0 can be provided. The optimal control theory approach to ACT control law synthesis yielded comparable control law performance much more systematically and directly than the classical s-domain approach. The ACT control law performance, although somewhat degraded by the inclusion of representative nonlinearities, remained quite effective. Certain high-frequency gust-load alleviation functions may require increased surface rate capability.

    Full Text Available The purpose of the article is to define the essence of project scope management process, its components, as well as to develop an algorithm of project scope management in terms of pharmaceutical production. Methodology. To carry out the study, available information sources on standards of project management in whole and elements of project scope management in particular are analysed. Methods of system and structural analysis, logical generalization are used to study the totality of subprocesses of project scope management, input and output documents, and to provide each of them. Methods of network planning are used to construct a precedence diagram of project scope management process. Results of the research showed that components of the project scope management are managing the scope of the project product and managing the content of project work. It is the second component is investigated in the presented work as a subject of research. Accordingly, it is defined that project scope management process is to substantiate and bring to the realization the necessary amount of work that ensures the successful implementation of the project (achievement of its goal and objectives of individual project participants. It is also determined that the process of managing the project scope takes into account the planning, definition of the project scope, creation of the structure of project work, confirmation of the scope and management of the project scope. Participants of these subprocesses are: customer, investor, and other project participants – external organizations (contractors of the project; project review committee; project manager and project team. It is revealed that the key element of planning the project scope is the formation of the structure of design work, the justification of the number of works, and the sequence of their implementation. It is recommended to use the following sequence of stages for creating the structure of project work

  10. Mergers: Success versus failure

    International Nuclear Information System (INIS)

    Carley, G. R.

    1997-01-01

    Successful mergers in the context of long-term value creation, as measured by return realized on investor-provided capital, were discussed. In essence, a successful merger is characterized by being motivated by a sound business reason and strategy for the merger, a reasonable price and sound execution. The acquiror's pre-merger success in managing a company is a good indicator of future success. Poorly managed companies that acquire other companies generally continue to be poorly managed with no significant increase in shareholder value. Prior to the acquisition, identification of the potential target, assessment of the people involved on both sides of the transaction, thorough knowledge of the target's potential for value creation, financial implications (debt, equity, terms and demand, tax implications, the potential effect of the proposed acquisition on the acquiror's business plan) and finally the execution of the process itself, are the important determinants of successful mergers

    Macro-and microjets facilities for generation of the round and plane subsonic jets are designed and fabricated. Automated measuring system (AMS - 2) for the spatial - temporal hot - wire anemometric visualization of jet flow field is designed and fabricated. Coordinate device and unit of the measurement, collecting, storage and processing of hot - wire anemometric information were integrated in the AMS. Coordinate device is intended for precision movement of the hot - wire probe in jet flow field according to the computer program. At the same time accuracy of the hot - wire probe movement is 5 microns on all three coordinates (x, y, z). Unit of measurement, collecting, storage and processing of hot - wire anemometric information is intended for the hot - wire anemometric measurement of the jet flow field parameters (registration of the mean - U and fluctuation - u' characteristics of jet flow velocity), their accumulation and preservation in the computer memory, and also carries out their processing according to certain programms.

    In this paper we study the boundary-layer separation produced in a high-speed subsonic boundary layer by a small wall roughness. Specifically, we present a direct numerical simulation (DNS) of a two-dimensional boundary-layer flow over a flat plate encountering a three-dimensional Gaussian-shaped hump. This work was motivated by the lack of DNS data of boundary-layer flows past roughness elements in a similar regime which is typical of civil aviation. The Mach and Reynolds numbers are chosen to be relevant for aeronautical applications when considering small imperfections at the leading edge of wings. We analyze different heights of the hump: The smaller heights result in a weakly nonlinear regime, while the larger result in a fully nonlinear regime with an increasing laminar separation bubble arising downstream of the roughness element and the formation of a pair of streamwise counterrotating vortices which appear to support themselves.

    The flow field behind a circular arc nozzle with exhaust jet was studied at subsonic free stream Mach numbers. A conical probe was used to measure the pitot pressure in the jet and free stream regions. Pressure data were recorded for two nozzle configurations at nozzle pressure ratios of 2.0, 2.9, and 5.0. At each set of test conditions, the probe was traversed from the jet center line into the free stream region at seven data acquisition stations. The survey began at the nozzle exit and extended downstream at intervals. The pitot pressure data may be applied to the evaluation of computational flow field models, as illustrated by a comparison of the flow field data with results of inviscid jet plume theory.

    Recent developments of the Green's function method and the computer program SOUSSA (Steady, Oscillatory, and Unsteady Subsonic and Supersonic Aerodynamics) are reviewed and summarized. Applying the Green's function method to the fully unsteady (transient) potential equation yields an integro-differential-delay equation. With spatial discretization by the finite-element method, this equation is approximated by a set of differential-delay equations in time. Time solution by Laplace transform yields a matrix relating the velocity potential to the normal wash. Premultiplying and postmultiplying by the matrices relating generalized forces to the potential and the normal wash to the generalized coordinates one obtains the matrix of the generalized aerodynamic forces. The frequency and mode-shape dependence of this matrix makes the program SOUSSA useful for multiple frequency and repeated mode-shape evaluations.

    A Large Field-of-View Particle Image Velocimetry (LFPIV) system has been developed for rotor wake diagnostics in the 14-by 22-Foot Subsonic Tunnel. The system has been used to measure three components of velocity in a plane as large as 1.524 meters by 0.914 meters in both forward flight and hover tests. Overall, the system performance has exceeded design expectations in terms of accuracy and efficiency. Measurements synchronized with the rotor position during forward flight and hover tests have shown that the system is able to capture the complex interaction of the body and rotor wakes as well as basic details of the blade tip vortex at several wake ages. Measurements obtained with traditional techniques such as multi-hole pressure probes, Laser Doppler Velocimetry (LDV), and 2D Particle Image Velocimetry (PIV) show good agreement with LFPIV measurements.

    2005-01-01

    Forecasts have indicated that despite some uncertainties in Coalbed methane (CBM) technology and concerns over the environmental effects of CBM production, the CBM industry is expected to grow rapidly over the next decade. This conference reviewed a variety of CBM project management strategies adopted by Canadian companies, ranging from initial site assessment through to commercial production. Pipeline and infrastructure requirements for the CBM industry were reviewed, and an overview of CBM regulations was provided. Exploration techniques and recommended practices for CBM hydraulic fracturing were presented. It was noted that in addition to environmental concerns over surface water discharge of CBM produced water, subsurface management issues are being increasingly scrutinized by environmentalists. Various commercialization strategies for CBM production were also reviewed, including well spacing management techniques; infrastructure demands and capitalized costs. Factors to ensure cost-effective high volume production in the shale gas industry were also reviewed. Of the 23 presentations given at this conference, 8 were catalogued separately for inclusion in this database. refs., tabs., figs
