Sample records for civil engineering genius

  1. Discovery Mondays: 'The civil engineering genius of the 100-metre deep underground caverns'

    CERN Multimedia

    2004-01-01

    CERN is first and foremost a place where physicists study particle collisions. But to be able to observe the infinitely small, they need huge pieces of equipment, the accelerators and detectors, whose construction, some 100 metres below the earth's surface calls on the services of other fascinating disciplines. Take civil engineering, for example. For the construction of the LHC some 420 000 cubic metres of rock have had to be excavated for the 6500 metres of tunnel, 6 new shafts and 32 underground chambers and caverns. To avoid disrupting other experiments in progress, the work on these exceptional structures has had to be done without creating vibrations. The ATLAS experiment hall, a huge cathedral-like structure 100 metres below ground, is another mind-blowing feat of civil engineering. Its construction involved the use of ground-breaking technology, such as the system for suspending the ceiling put in place during the excavation work. At the next Discovery Monday, the specialists responsible for...

    Powell, Philip M.

    1987-01-01

    The article reviews six conceptions of genius and offers a seventh. Three types of genius (analytic, synthetic, and integrated) are defined. Common to all three is the sustained ability to use analysis and synthesis (i.e., to be both linear and creative in approaching complex problems). (Author/DB)

  4. Reverse engineering genius: historiometric studies of superlative talent.

    Science.gov (United States)

    Simonton, Dean Keith

    2016-08-01

    Although genius has been defined in the dictionary as requiring an IQ above 140, this definition depends on an arbitrary methodological decision made by Lewis Terman for his longitudinal study of more than 1500 intellectually gifted children, a study that occupies four of the five volumes of Genetic Studies of Genius. Yet, only the second volume, by Catharine Cox, studied bona fide geniuses, by applying historiometric methods to 301 highly eminent creators and leaders. After defining historiometric research, I examine the difference between historical genius and intellectual giftedness with respect to heterogeneous intellects, personality differences, and early development and show that the actual relation between IQ and genius is small and heavily contingent on domain-specific assessment, the operation of traits like persistence and openness to experience, and the impact of diversifying experiences, including both developmental adversity and subclinical psychopathology. Hence, the dictionary definition of "genius" has minimal, if any, justification. If, using historiometric methods, one works backward from recognized geniuses, such as those studied by Cox, one might not obtain the kind of sample that Terman obtained for his longitudinal study. The two methods produce two distinct subgroups of the larger population. © 2016 New York Academy of Sciences.

    2001-01-01

    Construction work on the civil engineering contract started at Point 5 in August 1998. The new surface buildings and underground structures are necessary to accommodate the CMS detector for the LHC Project. The principal underground works consist of two new shafts, two parallel caverns separated by a supporting pillar, and a number of small connection tunnels and service galleries. A dispute resolution procedure has been included in the contract, whereby a Panel of Adjudicators may be called upon to make a decision in the case of a difference or dispute between the parties. The aim of this paper is to present CERN's first experience of civil engineering Adjudication arising from problems encountered with the ground freezing technique employed to allow construction of two new shafts.

  3. Claims in civil engineering contracts

    CERN Document Server

    Speirs, N A

    1999-01-01

    This paper considers claims arising during civil engineering construction contracts. The meaning of the word 'claim' is considered and its possible implications for additional cost and time to completion. The conditions of the construction contract selected will influence the risk apportionment between contractor and client and the price offered by the contractor for the work. Competitive bidding constraints and profit margins in the construction industry, however, may also influence the price offered. This in turn can influence the likelihood of claims arising. The client from his point of view is concerned to complete the work within an agreed time and budget. The circumstances under which claims may arise are reviewed in relation to typical conditions of contract. These circumstances are then related to the CERN LHC civil works. Ways of avoiding claims, where this is possible, are considered. Finally, the means of evaluation of claims and their settlement are considered.

    2012-02-01

    Full Text Available The civil engineering industry now faces with many problems such as poorly planned projects, breach of the delivery date, erroneous budget estimation, uncontrolled system functionality changes, and inappropriate documentation that all lead to the dissatisfaction of clients. One of the main concerns of civil engineering industry is to develop the talent of its human resources, since the quality and innovation of its products and services depend to a great extent on the knowledge, the ability and the talent that civil engineers apply in the development process. A competency framework defines a set of knowledge, skills, and behaviors that professionals must have to excel in their careers. A competency framework facilitates the identification of training needs and guides the design of a professional development program. In this paper we propose a competency framework for civil engineers, whose design is based on the activities and interactions that they perform during the civil development process. Thus, competency framework for civil engineers defines a set of knowledge, abilities and key behaviors, with special emphasis in the soft skills. The organization that adopts this framework must define and integrate the specific competencies needed by for civil engineers to allow them to fulfill their goals.

  16. CIVIL ENGINEERS' ROLES IN PUBLIC WORKS

    Science.gov (United States)

    Murata, Teruaki

    Recently, the public interests are becoming high in the way of executing public works and the future direction of infrastructure development, which raises nation-wide discussion on these issues. How should we make our country's growth strategy for sustainable development? How should we realize the grand design of infrastructure needed for the implementation of such a strategy? It is obvious that further discussions are needed for these challenging questions. With an aim to promote such discussions, this paper reviews the history of public works and the professional practices (or accomplishments) of our great civil engineers, and discusses the future of public works and the roles of civil engineers based on their origin. Further, in this paper, the author, as the chairman of the Public Works Committee of Japan Civil Engineering Contractors Association, introduces the Association's proposal of "realization of an attractive construction industry." However, for its realization, sustainable institutional arrangements under social consensus are indispensable. Also, individual engineer must establish his/her own identity based on sense of social ethics. It is the author's hope that, through these journals, the professional practices of civil engineers will be widely known to the public with objective logics and discussed to achieve social consensus.

    2004-01-01

    For more than a century, important civil engineering structures such as bridges, high-rise buildings, dams and marine platforms have contained iron or steel as the reinforcement for concrete or wood (ISIS Canada Strategic Plan, 2000). The useful lives of such structures have often been severely limited by the corrosion of this ferrous component. Much thought has been given in recent years to constructing structures that are lighter, stronger and non-corrosive. These innovative structures are new and for these to be accepted by the engineering community monitoring is mandatory. ISIS Canada has been developing such structures and monitoring them. In this paper, innovative bridge decks that have been implemented is described.

  8. Active IR-applications in civil engineering

    2002-06-01

    Applications of IR-thermography in civil engineering are not limited to the identification of heat losses in building envelopes. As it is well known from other areas of non-destructive testing, active IR-thermographic methods such as cooling down or lock-in thermography improves the results in many investigations. In civil engineering these techniques have not been used widely. Mostly thermography is used in a quasi-static manner. The interpretation of moisture measurements with thermography on surfaces can be very difficult due to several overlapping effects: emissivity changes due to composition, heat transfer through wet sections of the specimen, cooling through air flow or reflected spurious radiation sources. These effects can be reduced by selectively measuring the reflection in two wavelength windows, one on an absorption band of water and another in a reference band and then combining the results in a moisture index image. Cooling down thermography can be used to identify subsurface structural deficiencies. For building materials like concrete these measurements are performed on a much longer time scale than in flash lamp experiments. A quantitative analysis of the full cooling down process over several minutes can reliably identify defects at different depths. Experiments at BAM have shown, that active thermography is capabale of identifying structural deficiencies or moist areas in building materials much more reliable than quasi-static thermography.

    CERN Document Server

    Rammer, H

    1999-01-01

    For the first time at CERN, new shafts and caverns will be excavated inside a surface building. The LHC civil engineering construction for the ATLAS experiment has been designed such that the experimental hall will be completed to the extent that it can provide a secure, weatherproof and sound insulated covering to the shaft excavation area. The construction of the two access shafts and the experimental cavern will follow and will be carried out inside the building. This unconventional method of working allows the excavation of the Molasse rock in the dry, which is essential for this type of rock, and ensures reduced environmental pollution by noise and dust. The paper will present the technical infrastructure required for this particular construction method, explain its advantages and disadvantages, and compare it with a conventional method of underground excavations to be used on the same work site for the construction of the service cavern.

    CERN Document Server

    Alves, P; Pepinster, P; van Baaren, W; CERN. Geneva. ST Division

    2003-01-01

    The use and age of the civil engineering structure (office buildings, halls, tunnels) and of tertiary technical equipment (mainly HVAC and electricity) at CERN is such that their renovation must be considered in the near future. Due to the large number of buildings and equipment in these conditions, and the restricted budget available it is extremely important to define priorities. The aim of this paper is to give an overview of the current conditions and the related problems, based on data analysis of CERN database and confronting it with the inventory made at CERN by an external company. After having identified the most frequent problems and repairs to carry out, a planning for intervention is therefore presented optimizing the safety aspects, maintenance costs and comfort for the users. The timescale of this intervention is related to the money that will be available in the coming years.

    Energy Technology Data Exchange (ETDEWEB)

    Jaeger, Jean-Marc [SETEC TPI, Tour Gamma D 58, quai de la Rapee, 75583 Paris (France)

    2005-07-01

    SETEC TPI will address the 'Aging' topic of the Dijon Symposium by talking about: aging in civil engineering materials and structures, prevention of aging phenomena, in-operation monitoring of degradations related to aging and compensatory measures required to maintain a good safety level. Works as the Millau viaduct, the EdF skyscraper at La Defense - Paris, the renovation of the Grand Palais of Paris and special structures with Monaco's floating dam as well as the 'number 10' shaped gateway boat at Marseilles are illustrations for the issues discussed. The durability of civil engineering structures has become a major concern for designers. The Millau viaduct is designed for a service life of 120 years, and the Monaco dam for 100 years. Calculation rules have been evolving toward the incorporation of the concept of life cycle, for example, the Eurocodes 2 rules (reinforced concrete). The talk will expose the factors which are being taken into account to delay aging versus structure types. This part will be focused towards materials and corresponding regulations: - Reinforced concrete (coating of reinforcements, opening of cracks, choice of reinforcement types), BAEL and Eurocodes 2 rules; - Frame steel (protection, sacrificial anode), CM66 and Eurocodes 3 rules. New materials will also be mentioned: - Ultra high-performance fiber/concrete, with the example of CERACEM applied at Millau for the covering of the toll area barrier; - Titanium, which is starting to appear in the building trades, as for instance for the Beijing China Opera House shell. The second part of the talk will be devoted to a specific case namely, the 'number 10' shaped gateway bridge, a prestressed concrete structure immersed in the Port of Marseilles, which will be used to illustrate the aging phenomenon in a corrosive environment. We will focus on the types of inspection series performed by the Autonomous Port Authority of Marseilles to check the behavior of

  7. Pluridisciplinarity vs. interdisciplinarity in civil engineering education in seismic areas

    Directory of Open Access Journals (Sweden)

    Emil-Sever GEORGESCU

    2012-12-01

    Full Text Available Civil engineers are involved in building and maintaining a built environment that meets the sustainable development requirements. This environment is interdisciplinary in its nature, as it results from an interaction between different actors (architects, city planners, authorities, clients, civil engineers. Professional formation and training of engineers is a result of the didactic and technical efforts, which later will be reflected in the way constructions are being designed and built, so that engineers are not considered simple workers. Thus, when discussing professional formation and training of engineers, one should debate the necessary steps they have to take in their relationship with other disciplines. Practicing civil engineering in seismic risk areas in Romania adds specific requirements.

    2014-06-01

    How can leaders build an organization that is capable of innovating continually over time? By creating a community that is both willing and able to innovate. To be willing, the community must share a sense of purpose, values, and rules of engagement. When Luca de Meo was Volkswagen's head of marketing communication, he fostered a sense of purpose in his team by asking its members to reflect on what being part of VW meant to them; strengthened their shared values by encouraging them to use the brand's three components-innovation, responsibility, and value-to guide their work; and built significant responsibility and autonomy into their rules of engagement. To be able, companies must generate ideas through discourse and debate; experiment quickly, reflect, and adjust; and make decisions that combine disparate and even opposing ideas. Bill Coughran, an SVP of engineering at Google, employed these capabilities both to solve the company's near-term data storage needs and to make progress toward a next-generation solution.

    2013-01-01

    The potential hazard resulting from uncontained turbine engine rotor blade failure has always been the long-term concern of each aero engine manufacturer,and to fully contain the failed blades under critical operating conditions is also one of the most important considerations to meet the rotor integrity requirements.Usually,there are many factors involving the engine containment capability which need to be reviewed during the engine design phases,such as case thickness,rotor support structure,blade weight and shape,etc.However,the premier method to demonstrate the engine containment capability is the fan blade-off test and margin of safety (MS) analysis.Based on a concrete engine model,this paper aims to explain the key points of aero engine containment requirements in FAR Part 33,and introduces the implementation of MS analysis and fan blade-off test in the engine airworthiness certification.Through the introduction,it would be greatly helpful to the industrial community to evaluate the engine containment capability and prepare the final test demonstration in engine certification procedure.

  16. Situated learning methodologies and assessment in civil engineering structures education

    Science.gov (United States)

    Bertz, Michael Davis

    This thesis describes an overarching study of civil engineering undergraduate structural education through student performance in recalling and applying basic structural engineering knowledge, and the viability of alternative situated learning environments for more effectively supporting the learning of this knowledge. To properly ground this study, a thorough investigation of related work in assessment, cognitive science, educational technology, and design education was completed, with connections and applications to civil engineering education highlighted. The experimental work of the thesis is organized into three parts: an assessment of civil engineering undergraduates' fundamental structural engineering knowledge and abilities; the development and testing of a software support environment for situated learning, the Civil Engineering Learning Library (CELL); and, the implementation and evaluation of the design studio, a pedagogical model for situated learning in the classroom. The results of the assessment study indicate that civil engineering seniors (and also students earlier in the curriculum) have difficulty retaining and applying basic knowledge of structural behavior, especially doing so in a flexible fashion in design situations. The survey also suggests that visualization plays an important role in understanding structural behavior. Tests with the CELL system show that a cognitively-flexible multimedia environment can support structural learning, but were inconclusive about whether the computer-based system helped the students to learn better than conventional classroom lecture. Two trial implementations of the design studio indicate that the studio model can serve as a powerful situated learning environment, and that it can be scaled up to reasonable class sizes. Significant requirements are associated with this model, however, primarily in faculty involvement, but also in physical resources and student time. In addition to these conclusions about the

  1. Morphological Characteristics of the Language used in Civil Engineering

    Directory of Open Access Journals (Sweden)

    Liliana RICINSCHI

    2014-12-01

    Full Text Available This paper aims at investigating the particular features of civil engineering written discourse. A first assumption is made that the language employed in civil engineering is a subcategory of English for Specific Purposes. As part of ESP, it is thus bound to have a set of specialized lexical and grammatical features which are not in the repertoire of the non-users of that particular domain: complex noun phrases, special use of articles, special use of modal verbs, frequency of the passive voice and of present tense simple, long complex sentences, collocations, specialized terminology. Focus will be laid on demonstrating that the morphological features mentioned above are present in the texts selected for analysis. The texts belong to different domains related to civil engineering, namely steel structures, concrete constructions, building materials and railway systems. Two main morphological categories will be analysed in detail, i.e. the noun and the verb. In the part referring to the nominal component, the noun phrases used in the corpus, the special use of the articles and a process which we consider typical for this type of discourse, i.e. nominalisation, will be investigated. In the section focusing on the verb, the voice, tense, aspect and the values of the modal verbs used in civil engineering texts will be analysed.

    Ghostly figures can be seen wandering the cavern that will eventually house the ATLAS experiment, part of the LHC at CERN. Quite fitting since the detector will hunt the illusive 'ghostly' particles, such as the Higgs boson and dark matter. These engineers are excavating the huge cavern that has to be anchored from above as the detector will fill so much space that there is no room for support pillars.

    This special issue of Journal of Geophysics and Engineering offers a diverse panorama of approaches and technologies that aim to characterize and analyse the state of conservation and health of cultural heritage and civil infrastructure. In particular, it provides a significant overview not only of the effectiveness but also of the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques. The choice of diagnostic strategy depends on the material (concrete, masonry), the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment, etc). The paper by Fornaro et al reports an important technological advance in the field of slow deformation monitoring of civil infrastructure by means of differential interferometric synthetic aperture radar (SAR) from satellite platforms. The paper shows how the joint exploitation of the last generation of X-band SAR sensors, such as TerraSAR-X, and novel tomographic approaches makes possible advanced multi-dimensional imaging of real structures such as the Las Vegas Monorail. Within the same SAR-based applications, Tapete et al tested the capability of persistent scatterer interferometry (PSI) techniques in the preventative diagnosis of deformation threatening the structural stability of archaeological monuments and buried structures in the Roman Forum, Palatino Hill and Oppio Hill in the centre of Rome. A PSInSAR processing approach, based on the use of the SqueeSAR algorithm, has been shown to be highly suitable for retrieving not only information about displacements of the archaeological remains, but also evidence of criticalities affecting partially or totally buried structures, such as those discovered at Nero's Golden

    Full Text Available Substantial changes, not only in the demographic composition of the Australian workforce, but also,in the roles and expectations of men and women, have led to organisational and employee attempts to reconcile work and non-work demands. Research suggests that when work-family balance practices are introduced they can greatly enhance organisational efficency. However factors embedded in the organisational culture can undermine these policies rendering them ineffective. This quantitative study examined the relationship between the perceptions of a supportive work culture and some work and non-work experiences of Australian male civil engineers. The research investigated the prevalence of organisational values supportive of work-life balances as well as the level of work-family conflict perceived by those engineers. This paper reports some initial results of the study. These indicated that male civil engineers experienced moderate levels of work-family conflict but do not perceive their organisations to be very supportive of employee nneeds to balance work and personal life. However those that reported a supportive work environment also reported higher levels of organisational commitment, greater job and life satisfaction as well as lower level of work-family conflict and lower intentions to quit. The implications of the findings for organisations employing civil engineers are discussed.

    Full Text Available The profession of Civil Engineer requires beyond what you think of good courses and studies, it requires its employees to act with all the intensity of their intelligence and skills. This study aimed to analyze the profile of Civil Engineering students of a college in the state of São Paulo, and its specific purpose was to identify the logical-mathematical and spatial intelligences among them in their respective semesters. Therefore chose to research qualitative and inductive nature and exploratory. It was applied in the classroom a semi-structured questionnaire where your respondents were students enrolled from first to tenth semester during the second half of 2015, and this sample was separated randomly 20% of its total. The results showed that the profile of these students still needs to be worked professionally since the requirement lies with calculations and space notions.

  1. LHC Civil Engineering Construction Contracts Cost Monitoring and Budget Forecasting

    CERN Document Server

    Skelton, K

    2000-01-01

    The Civil Engineering project for the LHC is estimated at 350 MCHF, of which about 316 MCHF is for the construction contracts. These contracts are based on a system of remeasurement whereby the consultant estimates the quantities required for the construction of each structure and the contractor commits himself to the unit price, which define the initial tender price. There are many factors that affect the final price for these contracts, from increases or decreases in quantities of the estimated amounts in the original bill of quantities to variations to the contract. This paper will look at how these factors change costs at the individual level of a structure to the overall costs of the contract. It will look at how the Civil Engineering Group monitors these changes to calculate cash flows and final costs and how this information is used as a basis for budget forecasts.

  2. Outsourced design services lessons learned from LHC civil engineering

    CERN Document Server

    Watson, T

    2003-01-01

    In April 1996 CERN awarded three contracts for the provision of civil engineering design and site supervision services associated with the LHC Project. These three contracts with an average value at signature of 12MCHF were placed using the “two envelope” award system. Eight firms from six member states were integrated into three Joint Ventures. For Projects prior to the LHC, CERN would have carried out the design and supervision using in-house staff. The change to out-sourced services represented a major step for CERN. After seven years, the contracts are now coming to their conclusion. This paper aims to discuss the reasons why these contracts were originally implemented, the lessons than have been learnt over the last seven years and conclusions on how CERN could approach the need for civil engineering design services in the future.

    Osborne, J A

    1999-01-01

    Civil engineering work commenced in August 1998 at LEP Point 5 for the underground and surface works necessary to accommodate the CMS detector for the LHC project. The principal underground works consist of two parallel caverns, separated by a support pillar, two new shafts, a number of smaller connection and service galleries and tunnel enlargements on the existing LEP tunnel. The surface works consist of the 140 m long SX building for the detector assembly and numerous other steel and concrete structures necessary for the installation and operation of CMS. The civil engineering design and supervision has been awarded to a joint venture of Gibb (UK), SGI (Switzerland) and Geoconsult (Austria), and the contracting to a joint venture of Dragados (Spain) and Seli (Italy) for 112 MCHF. The aim of this paper is to discuss the management of this contract and in particular how the various parties interact in order to work most efficiently.

    1999-01-01

    Since July 1994, the CERN Civil Engineering group within the ST division has been preparing and engaging contracts related to the Large Hadron Collider (LHC) project. Several of these contracts have values in excess of 10 MCHF and will be executed over a number of years; as such they represent an important part of the infrastructure works required for the LHC. To date, in excess of two hundred and fifty companies have been consulted in relation to these contracts. Contracts or orders have been placed with over thirty companies or joint ventures of companies from nearly all the CERN Member States. This paper aims to show the inter-relationships between these contracts and how the Civil Engineering group is carrying out the management of these important LHC contracts. The organization of the group will be explained along with the roles of individual members within the group.

    2014-06-01

    Full Text Available The work of Building and Civil engineering demands a greater knowledge, skill and precision in quantity estimation.The manual method of estimating quantities for building and civil engineering works has posed potential problem areas on work that is undertaken. The low reliability of manual estimation indicates discrepancies in the accuracy of quantities computed manually,hence,the introduction of a digital computation.It is envisaged that this method will greatly reduce the complexities of different aspects when computing quantities for projects, as well as reduce the time to complete the computation and therefore projects can be started earlier.The paper reviewed the procedures involved in the development of a computer program for the digital computation of Building and Civil engineering quantities.The program was developed using Microsoft Visual C SHARP (C# programming language and Microsoft Visual studio. The steps/procedure used in achieving the development of the computer program was (1.designing the application interface,(2 adding controls to the window and (3writing codes behind the interface.The digital computation was tested using a proposed Road project and a proposed administrative buildingand the results showed an average of 100% of the items has 0 to 10 percentage difference for the road and 92% for the building in the final outputs of the quantities obtained through the manual computation and the digital computation and the software could therefore be said to be accurate and reliable.

    2013-06-20

    Behavior analysis of construction safety systems is of fundamental importance to avoid accidental injuries. Traditionally, measurements of dynamic actions in civil engineering have been done through accelerometers, but high-speed cameras and image processing techniques can play an important role in this area. Here, we propose using morphological image filtering and Hough transform on high-speed video sequence as tools for dynamic measurements on that field. The presented method is applied to obtain the trajectory and acceleration of a cylindrical ballast falling from a building and trapped by a thread net. Results show that safety recommendations given in construction codes can be potentially dangerous for workers.

    2016-01-01

    This collection focuses on the development of novel approaches to address one of the most pressing challenges of civil engineering, namely the mitigation of natural hazards. Numerous engineering books to date have focused on, and illustrate considerable progress toward, mitigation of individual hazards (earthquakes, wind, and so forth.). The current volume addresses concerns related to overall safety, sustainability and resilience of the built environment when subject to multiple hazards: natural disaster events that are concurrent and either correlated (e.g., wind and surge); uncorrelated (e.g., earthquake and flood); cascading (e.g., fire following earthquake); or uncorrelated and occurring at different times (e.g., wind and earthquake). The authors examine a range of specific topics including methodologies for vulnerability assessment of structures, new techniques to reduce the system demands through control systems; instrumentation, monitoring and condition assessment of structures and foundations; new te...

  3. Geophysical Methods for Non-Destructive Testing in Civil Engineering

    Science.gov (United States)

    Niederleithinger, E.

    2013-12-01

    Many non-destructive testing (NDT) methods for civil engineering (e. g. ultrasonics, radar) are similar to geophysical techniques. They just differ in scale, material under investigation and vocabulary used. In spite of the fact that the same principles of physics and mathematics apply to both fields, exchange has been limited in the past. But since a few years more and more geophysical knowledge is used in civil engineering. One of the focal points in research is to improve ultrasonic testing of concrete to be able to image the inside even of large, complex structures and to detect any deterioration as early as possible. One of the main issues is the heterogeneity of concrete, including aggregates, reinforcement, cracks and many other features. Our current research focuses on three points. One is the application of state of the art geophysical migration techniques as Reverse Time Migration (RTM) to image vertical faces or the backside of voids and ducts in thick concrete structures, which isn't possible with conventional techniques used in NDT. Second, we have started to use seismic interferometric techniques to interpolate ultrasonic traces, which can't be measured directly for technical reasons. Third, we are using coda wave interferometry to detect concrete degradation due to load, fatigue, temperature or other influences as early as possible. Practical examples of the application of these techniques are given and potential future research directions will be discussed. It will be shown, how a subset of these techniques can be used for innovative monitoring systems for civil infrastructure.

    Construction work on the civil engineering contracts at Point 1 and Point 5 started in 1998. The new surface buildings and underground structures are necessary to accommodate the ATLAS and CMS detectors for the LHC Project. The principal underground works at both points consist of two new shafts, two caverns along with a number of small connection tunnels and galleries. At Point 1, the works are 90% complete. Most of the surface buildings as well as the shafts and one of the two new caverns have been completed, and the construction of the second cavern is well underway. At Point 5, the works are 70% complete. Most of the surface buildings as well as the shafts and the pillar have been completed. With excavation of the two large caverns complete, the concreting of the final linings has started. The aim of this paper is to present the status of the civil engineering on these worksites and in particular the challenges encountered constructing the experimental caverns.

    2013-01-01

    Full Text Available Civil engineering is a branch of science that covers a broad range of areas where experimental procedures often plays an important role. The research in this field is usually supported by experimental structures able to test physical and mathematical models and to provide measurement results with acceptable accuracy. To assure measurement quality, a metrology probabilistic approach can provide valuable mathematical and computational tools especially suited to the study, evaluation and improvement of measurement processes in its different components (modeling, instrumentation performance, data processing, data validation and traceability, emphasizing measurement uncertainty evaluation as a tool to the analysis of results and to promote the quality and capacity associated with decision-making. This paper presents some of the research held by the metrology division of the Portuguese civil engineering research institutes, focused on the contribution of measurement uncertainty studies to a variety of frameworks, such as testing for metrological characterization and physical and mathematical modeling. Experimental data will be used to illustrate practical cases.

For any project to be successful the project team members must take collective and individual responsibility for their role in the project implementation. The organisational goal is “to make money now and in the future”. To achieve this goal the organization must provide value to its clientele. The clients are searching for the silver bullet; double the performance at half the price. TQM provides a means to achieve this goal.

    Nellen, Philipp M.; Broennimann, Rolf; Sennhauser, Urs J.; Askins, Charles G.; Putnam, Martin A.

    1995-09-01

    We report on civil engineering applications of wavelength multiplexed optical-fiber Bragg grating arrays produced directly on the draw tower for testing and surveying advanced structures and material like carbon fiber reinforced concrete elements and prestressing tendons. We equipped a 6 m X 0.9 m X 0.5 m concrete cantilever beam reinforced with carbon fiber lamellas with fiber Bragg grating sensors. Static and dynamic strain levels up to 1500 micrometers /m were measured with a Michelson interferometer used as Fourier spectrometer with resolutions of about 10 micrometers /m for all sensors. Comparative measurements with electrical resistance strain gauges were in good agreement with the fiber optic results. We used the fiber sensors in two different arrangements: some Bragg grating array elements measured the local strain while others were configured in an extensometric way to measure moderate strain over 0.1-1 m.

    Nellen, Philipp M.; Broennimann, Rolf; Frank, Andreas; Mauron, Pascal; Sennhauser, Urs J.

    1999-12-01

    In civil engineering it is of interest to monitor long-term performance of structures made of new lightweight materials like glass or carbon fiber reinforced polymers (GFRP/CFRP). In contrast to surface applied optical fiber sensors, embedded sensors are expected to be better protected against rough handling and harsh environmental conditions. We report on two recently done fiber optical sensor applications in civil engineering. Both include structurally embedded fiber Bragg grating (BG) arrays but have different demands with respect to their operation. For the first application fiber BGs were embedded in GFRP rockbolts of 3 - 5 m in length either of 3, 8, or 22 mm diameter. The sensor equipped rockbolts are made for distributed measurements of boulder motion during tunnel construction and operation and should withstand strain up to 1.6%. Rockbolt sensors were field tested in a tunnel near Sargans in Switzerland. For a second application fiber BGs were embedded in CFRP wires of 5 mm diameter used for the pre- stressing cables of a 56 m long bridge near Lucerne in Switzerland. The permanent load on the cable corresponds to 0.8% strain. Due to the embedded sensors, strain decay inside the cable anchoring heads could be measured for the first time during loading and operation of the cables. For both applications mechanical and thermal loading tests were performed to assess the function of these new elements. Also, temperature and strain sensitivity were calibrated. Reliability studies with respect to stress transfer, fiber mechanical failure, and wavelength shift caused by thermal BG decay as well as monitoring results of both applications are presented.

  15. Assessing the Use of Failure Case Studies in Civil Engineering Education

    Directory of Open Access Journals (Sweden)

    Elleithy Wael

    2016-01-01

    Full Text Available Civil engineering failures, unfortunately, occur from time to time leading to serious consequences. It is of importance that civil engineering undergraduate students are made aware of cases of failure in the past, and hence, to enhance their ability of identification of potential deficiencies. Investigating past cases of civil engineering failures has been carried out in UNMC for the last five years. The students are required to research, investigate and write essays reporting on these failures, detailing the causes and lessons learned. This study was conducted in order to assess the effectiveness of such approach. The outcomes of this study indicate that the use of civil engineering failure as case studies enhances the students’ educational experiences. In addition to the technical learning benefits from past civil engineering failure case studies, there are also impacts on students’ attitudes which has significant implications in their expected profession.

  17. Fiber-optic sensor applications in civil and geotechnical engineering

    Habel, Wolfgang R.; Krebber, Katerina

    2011-09-01

    Different types of fiber-optic sensors based on glass or polymeric fibers are used to evaluate material behavior or to monitor the integrity and long-term stability of load-bearing structure components. Fiber-optic sensors have been established as a new and innovative measurement technology in very different fields, such as material science, civil engineering, light-weight structures, geotechnical areas as well as chemical and high-voltage substations. Very often, mechanical quantities such as deformation, strain or vibration are requested. However, measurement of chemical quantities in materials and structure components, such as pH value in steel reinforced concrete members also provides information about the integrity of concrete structures. A special fiber-optic chemical sensor for monitoring the alkaline state (pH value) of the cementitious matrix in steel-reinforced concrete structures with the purpose of early detection of corrosion-initiating factors is described. The paper presents the use of several fiber-optic sensor technologies in engineering. One example concerns the use of highly resolving concrete-embeddable fiber Fabry-Perot acoustic emission (AE) sensors for the assessment of the bearing behaviour of large concrete piles in existing foundations or during and after its installation. Another example concerns fiber Bragg grating (FBG) sensors attached to anchor steels (micro piles) to measure the strain distribution in loaded soil anchors. Polymer optical fibers (POF) can be — because of their high elasticity and high ultimate strain — well integrated into textiles to monitor their deformation behaviour. Such "intelligent" textiles are capable of monitoring displacement of soil or slopes, critical mechanical deformation in geotechnical structures (dikes, dams, and embankments) as well as in masonry structures during and after earthquakes.

  18. Civil engineering work to raise the level of Route Goward

    CERN Multimedia

    2013-01-01

    Civil engineering work to raise the level of Route Goward will take place during Long Shutdown 1. The work will begin on 18 March 2013 and is expected to last around 5 months.   Route Goward runs over the top of the PS tunnel and is the only access route to the inside of the ring. The layer of shielding backfill beneath this road is the thinnest anywhere on the PS ring. As the purpose of this shielding is to protect against the ionising radiation emitted by the accelerator when in operation, this road has been classified as a “supervised radiation area” according to radiation protection regulations. This classification was merely a temporary solution and, on the recommendation of the PS Radiation Working Group (PSRWG), the decision has been taken to raise the surface level permanently by around 2 m in order to increase the thickness of the shielding and thus lower the dose rate to that of a non-designated area. As the PS tunnel itself is unable to withstand the weight of t...

    2017-01-01

    Full Text Available The article researches issues related to the relevance of applying renewable energy sources for civil engineering. The aim of the work is the study of modern approaches to designing buildings, using low-grade energy of the ground. The research methodology is based on the complex analysis of international design experience and on identifying the strengths and weaknesses of objects that use low-grade heat. We have identified the prospects of applying it for domestic construction practice. The state policy in the field of the efficient use of energy resources has been analyzed, and the vector of energy-saving programs development for the Samara Region has been defined. The research describes the impact of using geothermal energy on the architectural and planning solutions of buildings, as well as the peculiar features of the latter’s design, which are related primarily to the increase of energy efficiency. As a result, in the article a conclusion is made that the objects under investigation may be considered as one of the vectors of sustainable architecture development.

    Muography techniques applied to geological structures greatly improved in the past ten years. Recent applications demonstrate the interest of the method not only to perform structural imaging but also to monitor the dynamics of inner movements like magma ascent inside volcanoes or density variations in hydrothermal systems. Muography time-resolution has been studied thanks to dedicated experiments, e.g. in a water tower tank. This paper presents the activities of the DIAPHANE collaboration between particle- and geo-physicists and the most recent results obtained in the field of volcanology, with a focus on the main target, the Soufrière of Guadeloupe active volcano. Special emphasis is given on the monitoring of the dome's inner volumes opacity variations, that could be ascribed to the hydrothermal system dynamics (vaporization of inner liquid water in coincidence with the appearance of new fumaroles at the summit). I also briefly present results obtained in the fields of civil engineering (study of urban underground tunnels) and archaelogy (greek tumulus scanning).

  1. Charles Darwin: genius or plodder?

    Science.gov (United States)

    Wilkins, Adam S

    2009-11-01

    There is no doubt about the magnitude of Charles Darwin's contributions to science. There has, however, been a long-running debate about how brilliant he was. His kind of intelligence was clearly different from that of the great physicists who are deemed geniuses. Here, the nature of Darwin's intelligence is examined in the light of Darwin's actual style of working. Surprisingly, the world of literature and the field of neurobiology might supply more clues to resolving the puzzle than conventional scientific history. Those clues suggest that the apparent discrepancy between Darwin's achievements and his seemingly pedestrian way of thinking reveals nothing to Darwin's discredit but rather a too narrow and inappropriate set of criteria for "genius." The implications of Darwin's particular creative gifts with respect to the development of scientific genius in general are briefly discussed.

  11. Applications and issues of GIS as tool for civil engineering modeling

    Science.gov (United States)

    Miles, S.B.; Ho, C.L.

    1999-01-01

    A tool that has proliferated within civil engineering in recent years is geographic information systems (GIS). The goal of a tool is to supplement ability and knowledge that already exists, not to serve as a replacement for that which is lacking. To secure the benefits and avoid misuse of a burgeoning tool, engineers must understand the limitations, alternatives, and context of the tool. The common benefits of using GIS as a supplement to engineering modeling are summarized. Several brief case studies of GIS modeling applications are taken from popular civil engineering literature to demonstrate the wide use and varied implementation of GIS across the discipline. Drawing from the case studies, limitations regarding traditional GIS data models find the implementation of civil engineering models within current GIS are identified and countered by discussing the direction of the next generation of GIS. The paper concludes by highlighting the potential for the misuse of GIS in the context of engineering modeling and suggests that this potential can be reduced through education and awareness. The goal of this paper is to promote awareness of the issues related to GIS-based modeling and to assist in the formulation of questions regarding the application of current GIS. The technology has experienced much publicity of late, with many engineers being perhaps too excited about the usefulness of current GIS. An undoubtedly beneficial side effect of this, however, is that engineers are becoming more aware of GIS and, hopefully, the associated subtleties. Civil engineers must stay informed of GIS issues and progress, but more importantly, civil engineers must inform the GIS community to direct the technology development optimally.

    2014-01-01

    The Imperial College of Engineering (ICE or Kobu-Daigakko) in Tokyo, founded in 1873 under the auspices of the Ministry of Public Works, was one of the most prominent modern institutions of engineering education in early Meiji Japan. Previous studies have revealed that the ICE offered large scale practical training programs at enterprises of the Ministry, which sometimes lasted several months, and praised their ideal combination of theory and practice. In reality, it has been difficult to evaluate the quality of education at the ICE mainly because of scarcity of sources. ICE students published a collection of memoirs for alumni members, commemorating the fiftieth-year of the history of the Tokyo Imperial University. Drawing on the previously neglected collection of students' memoires, this paper appraises the education of civil engineering offered by the ICE. The paper also compares this collection with other official records of the college, and confirms it as a reliable source, even though it contains some minor errors. The author particularly uses the memoirs by Ayahiko Ishibashi, one of the first graduates from its civil engineering course, who left sufficient reminiscences on education that he received. This paper, as a result, illustrates that the main practical training for the students of civil engineering was limited to designing process, including surveying. Furthermore, practical training that Ishibashi received at those enterprises often lacked a plan, and its effectiveness was questionable.

    American Society for Testing and Materials. Philadelphia

    2006-01-01

    1.1 This practice covers the procedures for computing characteristic values of material properties of polymeric composite materials intended for use in civil engineering structural applications. The characteristic value is a statistically-based material property representing the 80 % lower confidence bound on the 5th-percentile value of a specified population. Characteristic values determined using this standard practice can be used to calculate structural member resistance values in design codes for composite civil engineering structures and for establishing limits upon which qualification and acceptance criteria can be based. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Non destructive testing of civil engineering infrastructures is becoming of primary importance for their diagnosis, residual time life estimation and/or structural health monitoring. A particularity of civil engineering application is the large size of the survey zones and the expected low cost of inspection. In this context non contact ultrasonics may offer the possibility to built robots that can automatically scan large areas (or eventually be integrated in moving vehicles) to recover mechanical properties of material or to perform imagery for geometrical information recovery. In this paper we present two possible applications of in situ laser ultrasonics : one is the detection of voids in tendon duct with the impact echo method, the other is the use of surface waves to recover mechanical properties of the first centimetres of concrete structures (here after called cover concrete).

    2017-01-01

    This book describes basic reliability concepts – parametric ALT plan, failure mechanism and design, and reliability testing with acceleration factor and sample size equation. A generalized life-stress failure model with a new effort concept has been derived and recommended to calculate the acceleration factor of the mechanical system. The new sample size equation with the acceleration factor has also been derived to carry out the parametric ALT. This new parametric ALT should help a mechanical/civil engineer to uncover the design parameters affecting reliability during the design process of the mechanical system. Consequently, it should help companies to improve product reliability and avoid recalls due to the product/structure failures in the field. As the improper or missing design parameters in the design phase are experimentally identified by this new reliability design method - parametric ALT, the mechanical/civil engineering system might improve in reliability by the increase in lifetime and the reduc...

    2016-04-01

    During capital and/or maintenance dredging operations, large amounts of material are produced. Instead of their discharge, dredged sediments may be a valuable natural resource if not contaminated. One of the possible areas of application is civil engineering. In the present work, the environmental status of seaport dredged sediment was evaluated in order to investigate its potential applicability as a secondary raw material. Sediments were analysed for element concentrations in digested samples, aqueous extracts and fractions from sequential extraction; for fluoride, chloride and sulphate concentrations in aqueous extracts; and for tributyltin (TBT). Granulometric and mineralogical compositions were also analysed. The elemental impact was evaluated by calculation of the enrichment factors. The total element concentrations determined showed moderate contamination of the dredged sediments as was confirmed also by their moderate enrichment factors, presumably as a result of industrial and port activities. Elemental concentrations in the aqueous extract were very low and therefore do not represent any hazard for the environment. The water-soluble element concentrations were under the threshold levels set by the EU Directive on the landfill of waste, on the basis of which the applicability of dredged sediments in civil engineering is evaluated, while the content of chloride and sulphate were above the threshold levels. It was found out that due to the large amounts of sediment available, civil engineering applications such as the construction of embankments and backfilling is the most beneficial recycling solution at present.

  4. Civil engineering at the crossroads in the twenty-first century.

    Ramírez, Francisco; Seco, Andres

    2012-12-01

    The twenty-first century presents a major challenge for civil engineering. The magnitude and future importance of some of the problems perceived by society are directly related to the field of the civil engineer, implying an inescapable burden of responsibility for a group whose technical soundness, rational approach and efficiency is highly valued and respected by the citizen. However, the substantial changes in society and in the way it perceives the problems that it considers important call for a thorough review of our structures, both professional and educational; so that our profession, with its undeniable historical prestige, may modernize certain approaches and attitudes in order to continue to be a reliable instrument in the service of society, giving priority from an ethical standpoint to its actions in pursuit of "the public good". It possesses important tools to facilitate this work (new technologies, the development of communications, the transmission of scientific thought.···); but there is nevertheless a need for deep reflection on the very essence of civil engineering: what we want it to be in the future, and the ability and willingness to take the lead at a time when society needs disinterested messages, technically supported, reasonably presented and dispassionately transmitted.

  5. Smart Sensing Technologies for Structural Health Monitoring of Civil Engineering Structures

    Directory of Open Access Journals (Sweden)

    M. Sun

    2010-01-01

    Full Text Available Structural Health Monitoring (SHM aims to develop automated systems for the continuous monitoring, inspection, and damage detection of structures with minimum labour involvement. The first step to set up a SHM system is to incorporate a level of structural sensing capability that is reliable and possesses long term stability. Smart sensing technologies including the applications of fibre optic sensors, piezoelectric sensors, magnetostrictive sensors and self-diagnosing fibre reinforced composites, possess very important capabilities of monitoring various physical or chemical parameters related to the health and therefore, durable service life of structures. In particular, piezoelectric sensors and magnetorestrictive sensors can serve as both sensors and actuators, which make SHM to be an active monitoring system. Thus, smart sensing technologies are now currently available, and can be utilized to the SHM of civil engineering structures. In this paper, the application of smart materials/sensors for the SHM of civil engineering structures is critically reviewed. The major focus is on the evaluations of laboratory and field studies of smart materials/sensors in civil engineering structures.

  6. Numerical Prediction of Differences in Micromechanical Fracture Sequence in Notched and Un-Notched Wires for Civil Engineering Applications

    Directory of Open Access Journals (Sweden)

    Adewole, K.K.

    2014-01-01

    Full Text Available The need to employ simulation-based investigations of fracture of civil engineering structures has been emphasised recently in literature. In this paper, three dimensional finite element simulations revealed that the cup and cone fracture process in channel-shaped notched wire for civil engineering applications begins with a slant fracture at the root of the outer edge of the channel-shaped notch and follows a slant to flat fracture sequence. These results demonstrate that the fracture origin in cup and cone fracture in notched wires for civil engineering applications does not necessarily begin with a flat fracture at the center of the wire and does not necessarily follows the flat to slant fracture sequence or propagation generally reported in literature. These results further demonstrate the need to employ simulation-based methodologies in conjunction with or as an alternative to purely experimental fractographic analysis for an accurate failure analysis of wires used for civil engineering applications.

  7. Defining Gas Turbine Engine Performance Requirements for the Large Civil TiltRotor (LCTR2)

    2013-01-01

    Defining specific engine requirements is a critical part of identifying technologies and operational models for potential future rotary wing vehicles. NASA's Fundamental Aeronautics Program, Subsonic Rotary Wing Project has identified the Large Civil TiltRotor (LCTR) as the configuration to best meet technology goals. This notional vehicle concept has evolved with more clearly defined mission and operational requirements to the LCTR-iteration 2 (LCTR2). This paper reports on efforts to further review and refine the LCTR2 analyses to ascertain specific engine requirements and propulsion sizing criteria. The baseline mission and other design or operational requirements are reviewed. Analysis tools are described to help understand their interactions and underlying assumptions. Various design and operational conditions are presented and explained for their contribution to defining operational and engine requirements. These identified engine requirements are discussed to suggest which are most critical to the engine sizing and operation. The most-critical engine requirements are compared to in-house NASA engine simulations to try to ascertain which operational requirements define engine requirements versus points within the available engine operational capability. Finally, results are summarized with suggestions for future efforts to improve analysis capabilities, and better define and refine mission and operational requirements.

  8. Exploring Advanced Technology Gas Turbine Engine Design and Performance for the Large Civil Tiltrotor (LCTR)

    Science.gov (United States)

    Snyder, Christopher A.

    2014-01-01

    A Large Civil Tiltrotor (LCTR) conceptual design was developed as part of the NASA Heavy Lift Rotorcraft Systems Investigation in order to establish a consistent basis for evaluating the benefits of advanced technology for large tiltrotors. The concept has since evolved into the second-generation LCTR2, designed to carry 90 passengers for 1,000 nautical miles at 300 knots, with vertical takeoff and landing capability. This paper explores gas turbine component performance and cycle parameters to quantify performance gains possible for additional improvements in component and material performance beyond those identified in previous LCTR2 propulsion studies and to identify additional research areas. The vehicle-level characteristics from this advanced technology generation 2 propulsion architecture will help set performance levels as additional propulsion and power systems are conceived to meet ever-increasing requirements for mobility and comfort, while reducing energy use, cost, noise and emissions. The Large Civil Tiltrotor vehicle and mission will be discussed as a starting point for this effort. A few, relevant engine and component technology studies, including previous LCTR2 engine study results will be summarized to help orient the reader on gas turbine engine architecture, performance and limitations. Study assumptions and methodology used to explore engine design and performance, as well as assess vehicle sizing and mission performance will then be discussed. Individual performance for present and advanced engines, as well as engine performance effects on overall vehicle size and mission fuel usage, will be given. All results will be summarized to facilitate understanding the importance and interaction of various component and system performance on overall vehicle characteristics.

    1997-12-31

    Concrete structures which are encountered at EDF, like all civil engineering structures, age. In order to adapt the maintenance conditions of these structures, particularly to extend their service life, and also to prepare constructions of future structures, tools for predicting the behaviour of these structures in their environment should be available. For EDF the technical risks are high and consequently very appropriate R and D actions are required. In this context the Direction des Etudes et Recherches (DER) has developed a methodology for analysing concrete structure behaviour modelling. This approach has several aims: - making a distinction between the problems which refer to the existing models and those which require R and D; - displaying disciplinary links between different problems encountered on EDF structures (non-linear mechanical, chemical - hydraulic - mechanical coupling, etc); - listing of the existing tools and positioning the DER `Aster` finite element code among them. This document is a state of the art of scientific knowledge intended to shed light on the fields in which one should be involved when there is, on one part a strong requirement on the side of structure operators, and on the other one, the present tools do not allow this requirement to be satisfactorily met. The analysis has been done on 12 scientific subjects: 1) Hydration of concrete at early ages: exothermicity, hardening, autogenous shrinkage; 2) Drying and drying shrinkage; 3) Alkali-silica reaction and bulky stage formation; 4) Long term deterioration by leaching; 5) Ionic diffusion and associated attacks: the chlorides case; 6) Permeability / tightness of concrete; 7) Concretes -nonlinear behaviour and cracking (I): contribution of the plasticity models; 8) Concretes - nonlinear behaviour and cracking (II): contribution of the damage models; 9) Concretes - nonlinear behaviour and cracking (III): the contribution of the probabilistic analysis model; 10) Delayed behaviour of

    Einstein, H.H.; Barvenik, M.J.

    1975-01-01

    A comprehensive description of grouting applications in civil engineering is presented that can serve as a basis for the selection of grouting methods in the borehole sealing problem. The breadth and depth of the study was assured by conducting the main part of the review, the collection and evaluation of information, without specifically considering the borehole sealing problem (but naturally incorporating any aspect of civil engineering applications that could be of potential use). Grouting is very much an art and not a science. In most cases, it is a trial and error procedure where an inexpensive method is initially tried and then a more expensive one is used until the desired results are obtained. Once a desired effect is obtained, it is difficult to credit any one procedure with the success because the results are due to the summation of all the methods used. In many cases, the method that proves successful reflects a small abnormality in the ground or structure rather than its overall characteristics. Hence, successful grouting relies heavily on good engineering judgement and experience, and not on a basic set of standard correlations or equations. 800 references. (JRD)

  13. Infrared Emissivity Measurements of Building and Civil Engineering Materials: A New Device for Measuring Emissivity

    Science.gov (United States)

    Monchau, Jean-Pierre; Marchetti, Mario; Ibos, Laurent; Dumoulin, Jean; Feuillet, Vincent; Candau, Yves

    2014-10-01

    The knowledge of the infrared emissivity of materials used in buildings and civil engineering structures is useful for two specific approaches. First, quantitative diagnosis of buildings or civil engineering infrastructures by infrared thermography requires emissivity values in the spectral bandwidth of the camera used for measurements, in order to obtain accurate surface temperatures; for instance, emissivity in the band III domain is required when using cameras with uncooled detectors (such as micro-bolometer arrays). Second, setting up accurate thermal balances by numerical modeling requires the total emissivity value for a large wavelength domain; this is, for instance, the case for computing the road surface temperature to predict ice occurrence. Furthermore, periodical surveys of emissivity variations due to aging or soiling of surfaces could be useful in many situations such as thermal mapping of roads or building insulation diagnosis. The use of portable emissivity measurement devices is required for that purpose. A device using an indirect measurement method was previously developed in our lab; the method uses measurement of the reflectivity from a modulated IR source and requires calibration with a highly reflective surface. However, that device uses a low-frequency, thermal modulation well adapted to laboratory measurements but unfit for fast and in situ measurements. Therefore, a new, portable system which retains the principle of an indirect measurement but uses a faster-frequency, mechanical modulation more appropriate to outdoor measurements was developed.

  19. Free vibration analysis of civil engineering structures by component-wise models

    Carrera, Erasmo; Pagani, Alfonso

    2014-09-01

    Higher-order beam models are used in this paper to carry out free vibration analysis of civil engineering structures. Refined kinematic fields are developed using the Carrera Unified Formulation (CUF), which allows for the implementation of any-order theory without the need for ad hoc formulations. The principle of virtual displacements in conjunction with the finite element method (FEM) is used to formulate stiffness and mass matrices in terms of fundamental nuclei. The nuclei depend neither on the adopted class of beam theory nor on the FEM approximation along the beam axis. This paper focuses on a particular class of CUF models that makes use of Lagrange polynomials to discretize cross-sectional displacement variables. This class of models are referred to as component-wise (CW) in recent works. According to the CW approach, each structural component (e.g. columns, walls, frame members, and floors) can be modeled by means of the same 1D formulation. A number of typical civil engineering structures (e.g. simple beams, arches, truss structures, and complete industrial and civil buildings) are analyzed and CW results are compared to classical beam theories (Euler-Bernoulli and Timoshenko), refined beam models based on Taylor-like expansions of the displacements on the cross-section, and classical solid/shell FEM solutions from the commercial code MSC Nastran. The results highlight the enhanced capabilities of the proposed formulation. It is in fact demonstrated that CW models are able to replicate 3D solid results with very low computational efforts.

  1. Utilization of electromigration in civil and environmental engineering--processes, transport rates and matrix changes.

    Ottosen, Lisbeth M; Christensen, Iben V; Rorig-Dalgård, Inge; Jensen, Pernille E; Hansen, Henrik K

    2008-07-01

    Electromigration (movement of ions in an applied electric field) is utilized for supply or extraction of ions from various porous materials within both civil and environmental engineering. In civil engineering, most research has been conducted on the removal of chlorides from concrete to hinder reinforcement corrosion while in environmental engineering remediation of heavy metal polluted soil is the issue most studied. Never the less, experiments have been conducted with utilization for several other materials and purposes within both engineering fields. Even though there are many topics of common interest in the use of electromigration for the two fields, there is no tradition for collaboration. The present paper is a review with the aim of pointing out areas of shared interest. Focus is laid on the purposes of the different processes, transport rates of various ions in different materials and on changes in the matrix itself. Desorption and dissolution of the target elements into ionic form is a key issue to most of the processes, and can be the limiting step. The removal rate is generally below 1 cm day(- 1), but it can be much less than 1 mm day(- 1) when desorption is slow and insufficient. Matrix changes occurs under the action of the applied electric field and it includes both physico-chemical and hydrological changes. Some of the solid phases is weathered and new can be formed. Increased fundamental understanding of the effects and side effects, when applying the electric field to a porous material, can lead to improvement of the known technologies and possibly to new applications.

    2017-06-01

    The use of the Discrete Element Method (DEM) for industrial civil engineering industrial applications is currently limited due to the computational demands when large numbers of particles are considered. The graphics processing unit (GPU) with its highly parallelized hardware architecture shows potential to enable solution of civil engineering problems using discrete granular approaches. We demonstrate in this study the pratical utility of a validated GPU-enabled DEM modeling environment to simulate industrial scale granular problems. As illustration, the flow discharge of storage silos using 8 and 17 million particles is considered. DEM simulations have been performed to investigate the influence of particle size (equivalent size for the 20/40-mesh gravel) and induced shear stress for two hopper shapes. The preliminary results indicate that the shape of the hopper significantly influences the discharge rates for the same material. Specifically, this work shows that GPU-enabled DEM modeling environments can model industrial scale problems on a single portable computer within a day for 30 seconds of process time.

    We report on civil engineering applications of a fiber optic distributed strain sensor. It consists of a sensing fiber and a high performance optical time domain reflectometer (OTDR), for measuring both strain and optical loss distribution along optical fibers by accessing only one end of the fiber. The OTDR can measure distributed strain with an accuracy of better than +/- 60 X 10-6 and a high spatial resolution of up to 1 m over a 10 km long fiber. In model experiments using the OTDR, we measured the strain changes in fibers attached to the surface of a concrete test beam. The performance of the fiber strain sensor was tested by measuring the strain distribution in optical fibers and comparing the results with resistance strain gage measurements for several loads. We found that the two sets of results were similar, and in addition, we demonstrated experimentally that the sensor was able to measure an induced strain change of less than 100 by 10-6, which is nearly the elastic limit of the concrete material. These results show the potential of the OTDR to extend the application of monitoring systems to such areas as large building diagnostics for civil engineering.

    Geosynthetics,factory-manufactured polymer materials,have been successfully used to solve many geotechnical problems in civil engineering.Two common applications are earth stabilization and erosion control.Geosynthetics used for earth stabilization include but are not limited to stabilized slopes,walls,embankments,and roads.Geosynthetics used for erosion control are mostly related to slopes,river channels and banks,and pond spillways.To enhance environmental sustainability,vegetation has been increasingly planted on the facing or surfaces of these earth structures.Under such a condition,geosynthetics mainly function as surficial soil stabilization while vegetation provides green appearance and erosion protection of earth surfaces.Recently,geosynthetic or geosynthetic-like material has been used to form green walls outside or inside buildings to enhance sustainability.Geosynthetics and vegetation are often integrated to provide combined benefits.The interaction between geosynthetics and vegetation is important for the sustainability of the earth and building wall surfaces.This paper provides a review of the current practice and research in the geosynthetic stabilization of vegetated earth and building surfaces for environmental sustainability in civil engineering with the emphases on geosynthetic used for erosion protection,geosynthetic-stabilized slopes,geosynthetic-stabilized unpaved shoulders and parking lots,and geosynthetic-stabilized vegetated building surfaces.

    2015-02-01

    In this paper, we report on the vibration and displacement monitoring of civil engineering structures using a state of the art image assisted total station (IATS) and passive target markings. By utilizing the telescope camera of the total station, it is possible to capture video streams in real time with 10fps and an angular resolution of approximately 2″/px. Due to the high angular resolution resulting from the 30x optical magnification of the telescope, large distances to the object to be monitored are possible. The laser distance measurement unit integrated in the total station allows to precisely set the camera's focus position and to relate the angular quantities gained from image processing to units of length. To accurately measure the vibrations and displacements of civil engineering structures, we use circular target markings rigidly attached to the object. The computation of the targets' centers is performed by a least squares adjustment of an ellipse according to the Gauß-Helmert model from which the parameters of the ellipse and their standard deviations are derived. In laboratory experiments, we show that movements can be detected with an accuracy of better than 0.2mm for single frames and distances up to 30m. For static applications, where many video frames can be averaged, accuracies of better than 0.05mm are possible. In a field test on a life-size footbridge, we compare the vibrations measured by the IATS to reference values derived from accelerometer measurements.

    For large civil engineering structures and base establishments, for example, bridges, super-high buildings, long-span space structures, offshore platforms and pipe systems of water & gas supply, their lives are up to a few decades or centuries. Damaged by environmental loads, fatigue effects, corrosion effects and material aging, these structures experience inevitably such side effects as damage accumulation, resistance reduction and even accidents. The traditional civil structure is a kind of passive one, whose performance and status are unpredictable to a great extent, but the informatics' introduction breaks a new path to obtain the status of the structure, thus it is an important research direction to evaluate and improve reliability of civil structures by the use of monitoring and health diagnosis technique, and this also assures the security of service for civil engineering structures. Smart material structure, originated from the aerospace sector, has been a research hotspot in civil engineering, medicine, shipping, and so on. For structural health monitoring of civil engineering, the research about high-performance sensing unit of smart material structure is very important, and this will possibly push further the development and application of monitoring and health diagnosis techniques. At present, piezoelectric materials are one of the most widely used sensing materials among the research of smart material structures. As one of the piezoelectric materials, PVDF(Polyvinylidene Fluoride)film is widely considered for the advantages of low cost, good mechanical ability, high sensibility, the ability of being easily placed and resistance of corrosion. However, only a few studies exit about building a mature monitoring system using PVDF. In this paper, for the sake of using PVDF for sensing unit for structural local monitoring of civil engineering, the strain sensing properties of PVDF are studied in detail. Firstly, the operating mechanism of PVDF is analyzed

    GPR was introduced in Spain in 1990, and the first significant work was the PhD thesis of H. Lorenzo in 1994. Due to its versatile applicability, the employ has been increased and actually, GPR is extensively used in detection of pipes, wiring and urban services mainly. During the last years, this method was also widely utilized in the detection of graves from the civil war and in forensic studies, with irregular results. It was also commonly applied in archaeology. Actually exists more than 20 private companies offering geotechnical services by means of GPR. Also, several public institutions as Universities and Research Institutes base part of their research in GPR or in GPR applications. Notwithstanding, no training courses of specific formation on GPR is offered, but in several doctorate programs it is possible to work with GPR. Also, in many schools, GPR is part of the geophysical formation of graduate students. However, no national guidelines and rules exist, and each company defines the investigation protocols. Nevertheless, one of the aims of the Comisión Española de Geodesia y Geofísica (Spanish Committee for Geodesy and Geophysics) is to define guidelines for the GPR studies. Probably, the existence of national guidelines or perhaps European guidelines could be the most effective way to promote the responsible use of GPR in different domains. On the other hand, perhaps recommendations on the use of combined methodologies could be a practical way to persuade in the application of geophysical non-destructive technologies. The CEDEX, Centro de Estudios y Experimentación de Obras Públicas (Center for Studies and Experimentation in Civil Engineering), which is a civil engineering research agency in Spain, offers different test sites to calibrate and evaluate the method. It is an autonomous organization, organically ascribed at present to the Ministry of Fomento, and functionally ascribed to the Ministries of Fomento and Medioambiente of Spain, giving

    2016-08-01

    Design for safety (DfS) (also known as prevention through design, safe design and Construction (Design and Management)) promotes early consideration of safety and health hazards during the design phase of a construction project. With early intervention, hazards can be more effectively eliminated or controlled leading to safer worksites and construction processes. DfS is practiced in many countries, including Australia, the UK, and Singapore. In Singapore, the Manpower Ministry enacted the DfS Regulations in July 2015, which will be enforced from August 2016 onwards. Due to the critical role of civil and structural (C&S) engineers during design and construction, the DfS knowledge, attitude and practices (KAP) of C&S engineers have significant impact on the successful implementation of DfS. Thus, this study aims to explore the DfS KAP of C&S engineers so as to guide further research in measuring and improving DfS KAP of designers. During the study, it was found that there is a lack of KAP studies in construction management. Therefore, this study also aims to provide useful lessons for future applications of the KAP framework in construction management research. A questionnaire was developed to assess the DfS KAP of C&S engineers. The responses provided by 43 C&S engineers were analyzed. In addition, interviews with experienced construction professionals were carried out to further understand perceptions of DfS and related issues. The results suggest that C&S engineers are supportive of DfS, but the level of DfS knowledge and practices need to be improved. More DfS guidelines and training should be made available to the engineers. To ensure that DfS can be implemented successfully, there is a need to study the contractual arrangements between clients and designers and the effectiveness of different implementation approaches for the DfS process. The questionnaire and findings in this study provided the foundation for a baseline survey with larger sample size, which is

    The use of high-temperature materials is especially important in power station construction,heating systems engineering, furnace industry, chemical and petrochemical industry, waste incineration plants, coal gasification plants and for flying gas turbines in civil and military aircrafts and helicopters. Particularly in recent years, the development of new processes and the drive to improve the economics of existing processes have increased the requirements significantly so that it is necessary to change from well-proven materials to new alloys. Hitherto, heat resistant ferritic steels sufficed in conventional power station constructions for temperatures up to 550℃ newly developed ferritic/martensitic steels provide sufficient strength up to about 600-620℃. In new processes, e.g. fiuidized-bed combustion of coal, process temperatures up to 900℃ occur. However, this is not the upper limit, since in combustion engines, e.g. gas turbines. Material temperatures up to 1100℃ are reached locally. Similar development trends can also be identified in the petrochemical industry and in the heat treatment and furnace engineering. The advance to ever higher material temperatures now not only has the consequence of having to use materials with enhanced high-strength properties, considerable attention now also has to be given to their chemical stability in corrosive media. Therefore not only examples of the use of high-temperature alloys for practical applications will be given but also be contributed to some general rules for material selection with regard to their high-temperature strength and corrosion resistance.

    Full Text Available The aim of this paper is to apply both time- and frequency-domain-based approaches on real-life civil engineering structures and to assess their capability for damage detection. The methodology is based on Principal Component Analysis of the Hankel matrix built from output-only measurements and of Frequency Response Functions. Damage detection is performed using the concept of subspace angles between a current (possibly damaged state and a reference (undamaged state. The first structure is the Champangshiehl Bridge located in Luxembourg. Several damage levels were intentionally created by cutting a growing number of prestressed tendons and vibration data were acquired by the University of Luxembourg for each damaged state. The second example consists in reinforced and prestressed concrete panels. Successive damages were introduced in the panels by loading heavy weights and by cutting steel wires. The illustrations show different consequences in damage identification by the considered techniques.

    The civil-engineering work for the construction of the Linac 4 accelerator has started on 22 October on the Mont Citron, the mound just opposite Restaurant No. 2 between the Computer Centre and the PS complex. Initially the work will involve excavating the mound and transporting the spoil to the area in front of Building SM18. This first phase of work will last for about five months until April 2009. The large number of lorries will cause disruption to traffic on the Route Rutherford, part of the Route Einstein and in the transfer tunnel between the two sites. Traffic lights for alternating traffic will be in operation at each end of the tunnel since there is insufficient room for two lorries travelling in opposite directions to use it at the same time. Consequently, users are strongly recommended not to use the tunnel except for transporting equipment between the two sites. Users not transporting equipment are strongly recommended ...

    Li, Jian; Ruiz-Sandoval, Manuel; Spencer, Billie F.; Elnashai, Amr S.

    2014-03-01

    System identification of civil engineering structures are often formulated as Multiple-Input, Multiple-Output (MIMO) problems due to the complexity of loading conditions such as differential ground motion, which is also multi-directional in nature. Such MIMO system identification problems are challenging due to strong coupling between the contributions of multiple ground motion inputs to each individual response. Compared with Single-Input, Multiple-Output (SIMO) system identification, MIMO problems are often more computationally complex and error prone. In this paper, a new system identification strategy is proposed in which a more complex MIMO problem is converted into a number of SIMO problems by decoupling the contribution of multiple inputs to the outputs. A QR-factorization based approach is adopted for the decoupling and its accuracy is investigated. The effectiveness of the proposed strategy is demonstrated through applications to a two-span straight bridge and a four-span curved bridge, both are highway bridges.

Different from conventional approaches, the EET provides a more comprehensive and objective way to systematically identify external energy factors affecting reliability. The EFM introduces energy loss into a traditional Function Model to identify internal energy sources affecting reliability. The combination creates a sound way to enumerate the energies to which a system may be exposed during its lifetime. We input these energies into planning an accelerated life test, a Multi Environment Over Stress Test. The test objective is to discover weak links and interactions among the system and the energies to which it is exposed, and design them out. As an example, the methods are applied to the pipe in subsea pipeline. However, they can be widely used in other civil engineering industries as well. The proposed method is compared with current methods.

    The Boeing Company is investigating the feasibility of building a second generation supersonic transport. If current studies support its viability, this airplane, known as the High Speed Civil Transport (HSCT), could be launched early in the next century. The HSCT will cruise at Mach 2.4, be over 300 feet long, have an initial range of between 5000 and 6000 NM, and carry approximately 300 passengers. We are presently involved in developing an advanced flight deck for the HSCT. As part of this effort we are undertaking a human engineering analysis that involves a top-down, mission driven approach that will allow a systematic determination of flight deck functional and information requirements. The present paper describes this work.

    In April 1996, CERN awarded three contracts for civil engineering design services associated with the LHC project. The three contracts were awarded to three different joint ventures of firms from five member states. The total bid price for these services was in excess of 35 MCHF and the contracts will run for up to seven years. This paper aims to discuss and analyze the experience gained to date in the management of these contracts. In particular, the paper will address the issues of conditions of contract and specification for this form of contract. Current experience with each of the three consultants will be presented with the areas of difficulty highlighted. Conclusions will be made regarding future use of such contracts and in particular the way in which CERN must change in order to work efficiently with external designers.

    The age of the civil engineering structure (office buildings, halls) and of tertiary technical equipment (mainly HVAC and electricity) at CERN is such that their renovation must be considered in the near future. Due to the large number of buildings and equipment in these conditions, and the restricted budget available, it is extremely important to define priorities. The aim of this note is to give the picture of the current conditions and the related problems, based on the backlog of CERN database (MP5) and confronting it with the inventory made at CERN by an external company. After having identified the most frequent problems and repairs to carry out, a planning for intervention is therefore presented optimizing the safety aspects, maintenance costs and comfort for the users. The timescale of this intervention is related to the money that will be available in the coming years.

    Ground Penetrating Radar (GPR) is a safe, non-destructive and non-invasive imaging technique that can be effectively used for advanced inspection of composite structures and for diagnostics affecting the whole life-cycle of civil engineering works. GPR provides high resolution images of structures and subsurface through wide-band electromagnetic waves. It can be employed for the surveying of roads, pavements, bridges, tunnels, for detecting underground cavities and voids, for utility sensing, for the inspection of buildings, reinforced concrete and pre-cast concrete structures, for geotechnical investigation, in foundation design, as well as for several other purposes. Penetration and resolution of GPR depend primarily on the transmitting frequency of the equipment, the antenna characteristics, the electrical properties of the ground or of the surveyed material, and the contrasting electrical properties of the targets with respect to the surrounding medium. Generally there is a direct relationship between the transmitter frequency and the resolution that can be obtained; conversely there is an inverse relationship between frequency and penetration depth. GPR works best in dry ground environments, but can also give good results in wet, saturated materials; it does not work well in saline conditions, in high-conductivity media and through dense clays which limit signal penetration. Different approaches can be employed in the processing of collected GPR data. Once data have been processed, they still have to be analysed. This is a challenging problem, since interpretation of GPR radargrams is typically non-intuitive and considerable expertise is needed. In the presence of a complex scenario, an accurate electromagnetic forward solver is a fundamental tool for the validation of data interpretation. It can be employed for the characterization of scenarios, as a preliminary step that precedes a survey, or to gain a posteriori a better understanding of measured data. It

    2009-12-01

    Full Text Available Oggi la teoria della conservazione urbana sta affrontando aspetti intangibili – notabilmente il concetto del “genius loci”. Ma questa idea potenzialmente vaga deve essere compresa nei termini che permettono un suo effettivo utilizzo. L’autore argomenta che tale questione può essere affrontata attraverso un approfondimento della complessità della scienza rivelando i modi attraverso i quali un sistema nella sua interezza può essere scomposto in elementi dinamici. All’interno dei tessuti storici noi siamo conservatori, siamo utilizzatori, siamo consumatori e, inevitabilmente, siamo coloro che attuano le modifiche. Il nostro compito non è di far resistere quell’insieme, ma di poterlo gestire in maniera più dinamica e di pretendere un più ampio concetto di conservazione. Questo atteggiamento va oltre il dualismo basato sul modello di pensiero del “genius loci” ma abbraccia una più efficace aspettativa di crescita organica.

    Full Text Available In a globalized era it is not enough to have a professional qualification to ensure economic and professional success. The academic background of professionals must be adequate to face challenges and solve problems of a globalized and dynamic world. Civil engineers face many complications when seeking an international career. There are many differences within the profession globally such as: resources, workforce, climate, language, culture, philosophies, regulations, etc. which raise the entry barriers to fully practice as a civil engineer. The International accreditations play a major role as the first evidence of the civil engineer technical proficiency. These assure the quality of the higher education curricula and add value to the human capital on an international context. Despite the fact that many Mexican Universities have academic programs which have international accreditations, civil engineer graduates cannot easily work across borders. This paper describes the impact that international accreditation has for civil engineers when seeking an international career.

    This paper investigates the applicability of CDM to civil engineering projects through a case study on the project to extend Port Samainda in Indonesia. The goal of this project is to improve the physical distribution system of the port so that it can accommodate increasing future demand for the cargo transportation. Based on the project report by JICA (2002), we first outline the predicted demand for the cargo transportation and select possible three options in which a cargo vessel with different capabilities and respective port facilities are assigned. For each option, CO2 emissions from both cargo and dredging vessels are predicted and compared. It is found that the total CO2 emission may be reduced significantly by introducing a large-draft vessel and deep navigation channels. This feature becomes more prominent if a traveling distance of the cargo vessels is long enough so that CO2 emissions from cargo vessels dominates those of dredging vessels. This observation supports the applicability of CDM to civil engineering projects because reduction of the CO2 emission is attained by improving distribution systems through civil engineering works such as extension of the port and the maintenance dredging. Finally, we discuss future problems to be investigated for the practical application of CDM to a civil engineering project.

    2015-05-01

    Mathematics and engineering are inexorably and significantly linked and essentially required in analyzing and accessing thought to make good judgment when dealing in complex and varied engineering problems. A study in the current engineering education curriculum to explore how the critical thinking and mathematical thinking relates to one another, is therefore timely crucial. Unfortunately, there is not much information available explicating about the link. This paper aims to report findings of a critical review as well as to provide brief description of an on-going research aimed to investigate the dispositions of critical thinking and the relationship and integration between critical thinking and mathematical thinking during the execution of civil engineering tasks. The first part of the paper reports an in-depth review on these matters based on rather limited resources. The review showed a considerable form of congruency between these two perspectives of thinking, with some prevalent trends of engineering workplace tasks, problems and challenges. The second part describes an on-going research to be conducted by the researcher to investigate rigorously the relationship and integration between these two types of thinking within the perspective of civil engineering tasks. A reasonably close non-participant observations and semi-structured interviews will be executed for the pilot and main stages of the study. The data will be analyzed using constant comparative analysis in which the grounded theory methodology will be adopted. The findings will serve as a useful grounding for constructing a substantive theory revealing the integral relationship between critical thinking and mathematical thinking in the real civil engineering practice context. The substantive theory, from an angle of view, is expected to contribute some additional useful information to the engineering program outcomes and engineering education instructions, aligns with the expectations of

    2015-10-01

    This paper examines how Fyodor Dostoevsky was used as an example in the debate over genius as a pathological phenomenon in nineteenth century medicine and criminal anthropology. When Dostoevsky's novels became known in Western Europe medical interest in the relation between genius and insanity reached its pinnacle. A known epileptic, Dostoevsky was exceptionally well suited to illustrate Cesare Lombroso's theory of genius as an epileptoid psychosis. Dostoevsky was also claimed as an example by the rivalling Lyon school, whose representatives argued that Dostoevsky's life and works demonstrate that genius is a higher form of health rather than a pathological deviation.

    Full Text Available The civil and environmental engineering disciplines have identified the levels of knowledge about sustainability that are desirable for students to achieve as they graduate with a bachelor’s degree, as well as sustainability-related competencies to be obtained during a master’s degree, and on-the-job, prior to professional licensure. Different pedagogies are better suited to help students attain these levels of cognitive ability, while also developing affective outcomes. This paper provides examples of different methods that have been used at one institution to educate engineering students about sustainability, supported with data that indicates whether the method successfully achieved the targeted learning outcomes. Lectures, in-class active learning, readings, and appropriately targeted homework assignments can achieve basic sustainability knowledge and comprehension by requiring students to define, identify, and explain aspects of sustainability. Case studies and the application of software tools are good methods to achieve application and analysis competencies. Project-based learning (PBL and project-based service-learning (PBSL design projects can reach the synthesis level and may also develop affective outcomes related to sustainability. The results provide examples that may apply to a wider range of disciplines and suggest sustainability outcomes that are particularly difficult to teach and/or assess.

    Full Text Available Scientific and professional interests of civil engineering mainly include structures, hydraulics, geotechnical engineering, environment, and transportation issues. Topics included in the context of the above may concern urban environment issues, urban planning, hydrological modelling, study of hazards and road construction. Land cover information contributes significantly on the study of the above subjects. Land cover information can be acquired effectively by visual image interpretation of satellite imagery or after applying enhancement routines and also by imagery classification. The Landsat Data Continuity Mission (LDCM – Landsat 8 is the latest satellite in Landsat series, launched in February 2013. Landsat 8 medium spatial resolution multispectral imagery presents particular interest in extracting land cover, because of the fine spectral resolution, the radiometric quantization of 12bits, the capability of merging the high resolution panchromatic band of 15 meters with multispectral imagery of 30 meters as well as the policy of free data. In this paper, Landsat 8 multispectral and panchromatic imageries are being used, concerning surroundings of a lake in north-western Greece. Land cover information is extracted, using suitable digital image processing software. The rich spectral context of the multispectral image is combined with the high spatial resolution of the panchromatic image, applying image fusion – pansharpening, facilitating in this way visual image interpretation to delineate land cover. Further processing concerns supervised image classification. The classification of pansharpened image preceded multispectral image classification. Corresponding comparative considerations are also presented.

    Veres, Joseph P.; Thurman, Douglas R.

    2010-01-01

    This paper focuses on the conceptual design of a two spool compressor for the NASA Large Civil Tilt Rotor engine, which has a design-point pressure ratio goal of 30:1 and an inlet weight flow of 30.0 lbm/sec. The compressor notional design requirements of pressure ratio and low-pressure compressor (LPC) and high pressure ratio compressor (HPC) work split were based on a previous engine system study to meet the mission requirements of the NASA Subsonic Rotary Wing Projects Large Civil Tilt Rotor vehicle concept. Three mean line compressor design and flow analysis codes were utilized for the conceptual design of a two-spool compressor configuration. This study assesses the technical challenges of design for various compressor configuration options to meet the given engine cycle results. In the process of sizing, the technical challenges of the compressor became apparent as the aerodynamics were taken into consideration. Mechanical constraints were considered in the study such as maximum rotor tip speeds and conceptual sizing of rotor disks and shafts. The rotor clearance-to-span ratio in the last stage of the LPC is 1.5% and in the last stage of the HPC is 2.8%. Four different configurations to meet the HPC requirements were studied, ranging from a single stage centrifugal, two axi-centrifugals, and all axial stages. Challenges of the HPC design include the high temperature (1,560deg R) at the exit which could limit the maximum allowable peripheral tip speed for centrifugals, and is dependent on material selection. The mean line design also resulted in the definition of the flow path geometry of the axial and centrifugal compressor stages, rotor and stator vane angles, velocity components, and flow conditions at the leading and trailing edges of each blade row at the hub, mean and tip. A mean line compressor analysis code was used to estimate the compressor performance maps at off-design speeds and to determine the required variable geometry reset schedules of the

    Fly ash based on biofuels or coal has been used as construction material for a long time in roads and other civil engineering applications. Some example, where it has been used in roadbase and subbase of gravel roads, are in the counties of Uppsala, Soedermanland, Vaestmanland and in Finland. The use of fly ash has contributed to good function for example as bearing capacity, thaw and frost capacity and good durability. This has also reduced costs for maintenance. The objective of this project was to develop a manual to provide a base for contemporary use of fly ash in road constructions. In the manual experience from studies, field tests and regulations has been compiled. The manual handles fly ash as base for products to be used in base and subbase in gravel roads. Future user of the guidelines are mainly consultant engineers and contractors. However the aim of the manual is to also support road administrators, environmental authorities and industry. The project has been carried out parallel to another ongoing national project titled 'Guidelines, Use of alternative materials in civil engineering'. The objective of that project is to establish a base for handling of alternative materials in Sweden. Fly ash in gravel roads are mainly used in two typical applications, one without any additive in a single layer and one with fly ash mixed with gravel. The use of flyash provides functional properties such as increased stiffness, stability and enhanced frost and thaw capacity for the road construction in total. Furthermore the products based on fly ash will have low permeability and good frost and thaw durability. These properties are for example related to fly ash quality, design and construction and are in general expected to be better than for traditional constructions using, for example, sand or gravel. The properties can be enhanced further by using binders such as cement and Merit. Fly ash should always be used above the ground water table with

    Full Text Available This contribution is dedicated to demonstrating the high potential and manifold applications of state-of-the-art computational fluid dynamics (CFD tools for free-surface flows in civil and environmental engineering. All simulations were performed with the academic research code ELBE (efficient lattice boltzmann environment, http://www.tuhh.de/elbe. The ELBE code follows the supercomputing-on-the-desktop paradigm and is especially designed for local supercomputing, without tedious accesses to supercomputers. ELBE uses graphics processing units (GPU to accelerate the computations and can be used in a single GPU-equipped workstation of, e.g., a design engineer. The code has been successfully validated in very different fields, mostly related to naval architecture and mechanical engineering. In this contribution, we give an overview of past and present applications with practical relevance for civil engineers. The presented applications are grouped into three major categories: (i tsunami simulations, considering wave propagation, wave runup, inundation and debris flows; (ii dam break simulations; and (iii numerical wave tanks for the calculation of hydrodynamic loads on fixed and moving bodies. This broad range of applications in combination with accurate numerical results and very competitive times to solution demonstrates that modern CFD tools in general, and the ELBE code in particular, can be a helpful design tool for civil and environmental engineers.

    Highlights: ► A seismic load can be of any type from force-controlled to displacement-controlled. ► Seismic input and structural features play a concurrent role in seismic load categorization. ► A margin index is introduced, which controls seismic load categorization. ► A formula is given for calculating the margin index. ► A formula is given that provides the primary part of a seismically-induced stress. -- Abstract: Both civil and mechanical engineers come across loads of the force-controlled type (qualified as “primary”) or of the displacement-controlled type (qualified as “secondary”). For decades, different authors with either civil or mechanical backgrounds have been debating whether a particular seismic load should be classified as primary or secondary, but without apparent mutual understanding or mutual benefit so far. The purpose of this paper is to bring some clarity to the subject by considering a family of oscillators, which are characterized by their ductile capacity, μ{sub u}, and their “effective stiffness factor”, τ. The considered range of τ values (0 < τ < 1) enables to cover all cases from the perfect damage to the perfect non-damage models. A structural index λ is also introduced, which is a mix of ductility and effective stiffness factor. It is concluded that a seismic input cannot be a priori regarded as primary or secondary. Both the λ value of the structure or component and the slope, p, of the input spectrum in the vicinity of its (dominant) natural frequency should be considered concurrently when making a decision about stress categorization. A margin index m is introduced, which controls seismic load/stress categorization. A formula is given that provides the primary part of a seismically-induced stress.

    2009-12-01

    Researchers at the University of Vermont were awarded a NSF-sponsored Department Level Reform (DLR) grant to incorporate a systems approach to engineering problem solving within the civil and environmental engineering programs. A systems approach challenges students to consider the environmental, social, and economic aspects within engineering solutions. Likewise, sustainability requires a holistic approach to problem solving that includes economic, social and environmental factors. Our reform has taken a multi-pronged approach in two main areas that include implementing: a) a sequence of three systems courses related to environmental and transportation systems that introduce systems thinking, sustainability, and systems analysis and modeling; and b) service-learning (SL) projects as a means of practicing the systems approach. Our SL projects are good examples of inquiry-based learning that allow students to emphasize research and learning in areas of most interest to them. The SL projects address real-world open-ended problems. Activities that enhance IT and soft skills for students are incorporated throughout the curricula. Likewise, sustainability has been a central piece of the reform. We present examples of sustainability in the SL and modeling projects within the systems courses (e.g., students have used STELLA™ systems modeling software to address the impact of different carbon sequestration strategies on global climate change). Sustainability in SL projects include mentoring home schooled children in biomimicry projects, developing ECHO exhibits and the design of green roofs, bioretention ponds and porous pavement solutions. Assessment includes formative and summative methods involving student surveys and focus groups, faculty interviews and observations, and evaluation of student work.

    2010-12-01

    Full Text Available La letteratura recente mostra i limiti della moderna teoria urbanistica di fronte alla complessità di un mondo nuovo che è il risultato di trasformazioni politiche, economiche e sociali. Il genius loci nella dimensione storica della città è quello che sopravvive alle strutture funzionali in continua evoluzione e conferisce un carattere indelebile alla città e al paesaggio, attraverso diversi fenomeni urbani, tutti parte di una esperienza unica e riconoscibile. La dimensione contemporanea della città storica, vale a dire il genius saeculi, richiede un continuo aggiornamento dei temi collettivi, degli spazi pubblici e dei contenuti che sono assegnati alle forme storiche dalle persone che vivono e abitano quei luoghi, e l’inserimento di nuovi significati, nuovi valori, nuove forme di vita sociale. Questa dunque è la sfida per il nuovo Millennio: conciliare lo spirito del luogo, il genius loci, con lo spirito del tempo, il genius saeculi, recuperando i valori della storia attraverso la loro conservazione e la loro combinazione nel tempo presente secondo un modello sostenibile.

    2015-12-01

    Full Text Available It is common knowledge that hedging devices as a rhetorical technique common in all persuasive writing are considerably important in scientific discourse, for they are tools which facilitate presenting claims or arguments in a polite, acceptable and respectful manner. In addition, they are discoursal resources available to a scientific writer’s propositions to express uncertainty, skepticism, and open-mindedness. Research articles are an important means of communication between different members of a discourse community, and will be convincing to a certain extent only when authors are able to employ rhetorical conventions, such as hedging devices, persuasively. However, hedging is a problematic aspect in EAP learning since rarely are the learners able to hedge their statements appropriately, engineering students not being an exception. Therefore, this article tends to linguistically analyze the function of rhetorical impact of using hedging devices in the results and discussion part of a civil engineering research article published in the Asian Journal of Civil Engineering (Building & Housing to conclude that a greater and more systematic attention should be given to hedging devices considering their importance in EAP. The implication is that students, especially the Non Native English Speakers, be taught how to recognize and effectively use hedging devices in their writing as they do not seem to be familiar with hedges and therefore find it particularly difficult to hedge their statements appropriately.

    Aging of transport infrastructures combined with traffic and climatic solicitations contribute to the reduction of their performances. To address and quantify the resilience of civil engineering structure, investigations on robust, fast and efficient methods are required. Among research works carried out at IFSTTAR, methods for long term monitoring face an increasing demand. Such works take benefits of this last decade technological progresses in ICT domain. The present study follows the ISTIMES European project [1], which aimed at demonstrate the ability of different electromagnetic sensing techniques, processing methods and ICT architecture, to be used for long term monitoring of critical transport infrastructures. Thanks to this project a multi-sensing techniques system, able to date and synchronize measurements carried out by infrared thermography coupled with various measurements data (i.e. weather parameters), have been designed, developed and implemented on real site [2]. Among experiments carried out on real transport infrastructure, it has been shown, for the "Musmesci" bridge deck (Italy), that by using infrared thermal image sequence with weather measurements during sevral days it was possible to develop analysis methods able to produce qualitative and quantitative data [3]. In the present study, added functionalities were designed and added to the "IrLAW" system in order to reach full autonomy in term of power supply, very long term measurement capability (at least 1 year) and automated data base feeding. The surveyed civil engineering structures consist in two concrete beams of 16 m long and 21 T weight each. One of the two beams was damage by high energy mechanical impact at the IFSTTAR falling rocks test station facilities located in the French Alpes [4]. The system is composed of one IR uncooled microbolometric camera (FLIR SC325) with a 320X240 Focal Plane Array detector in band III, a weather station VAISALA WXT520, a GPS, a failover power supply

  8. Advanced spatio-temporal filtering techniques for photogrammetric image sequence analysis in civil engineering material testing

    2016-01-01

    The paper shows advanced spatial, temporal and spatio-temporal filtering techniques which may be used to reduce noise effects in photogrammetric image sequence analysis tasks and tools. As a practical example, the techniques are validated in a photogrammetric spatio-temporal crack detection and analysis tool applied in load tests in civil engineering material testing. The load test technique is based on monocular image sequences of a test object under varying load conditions. The first image of a sequence is defined as a reference image under zero load, wherein interest points are determined and connected in a triangular irregular network structure. For each epoch, these triangles are compared to the reference image triangles to search for deformations. The result of the feature point tracking and triangle comparison process is a spatio-temporally resolved strain value field, wherein cracks can be detected, located and measured via local discrepancies. The strains can be visualized as a color-coded map. In order to improve the measuring system and to reduce noise, the strain values of each triangle must be treated in a filtering process. The paper shows the results of various filter techniques in the spatial and in the temporal domain as well as spatio-temporal filtering techniques applied to these data. The best results were obtained by a bilateral filter in the spatial domain and by a spatio-temporal EOF (empirical orthogonal function) filtering technique.

    Measuring the electrical permittivity of civil engineering materials is important for a range of ground penetrating radar (GPR) and pavement moisture measurement applications. Compacted unbound granular (UBG) pavement materials present a number of preparation and measurement challenges using conventional characterisation techniques. As an alternative to these methods, a modified free-space (MFS) characterisation approach has previously been investigated. This paper describes recent work to optimise and validate the MFS technique. The research included finite difference time domain (FDTD) modelling to better understand the nature of wave propagation within material samples and the test apparatus. This research led to improvements in the test approach and optimisation of sample sizes. The influence of antenna spacing and sample thickness on the permittivity results was investigated by a series of experiments separating antennas and measuring samples of nylon and water. Permittivity measurements of samples of nylon and water approximately 100 mm and 170 mm thick were also compared, showing consistent results. These measurements also agreed well with surface probe measurements of the nylon sample and literature values for water. The results indicate permittivity estimates of acceptable accuracy can be obtained using the proposed approach, apparatus and sample sizes.

    Fiber reinforced polymer (FRP) materials are currently used for strengthening civil engineering infrastructures. The strengthening system is dependant on the bond characteristics of the FRP to the external surface of the structure to be effective in resisting the applied loads. This paper presents an innovative self-monitoring FRP strengthening system. The system consists of two components which can be embedded in FRP materials to monitor the global and local behavior of the strengthened structure respectively. The first component of the system is designed to evaluate the applied load acting on a structure based on elongation of the FRP layer along the entire span of the structure. Success of the global system has been demonstrated using a full-scale prestressed concrete bridge girder which was loaded up to failure. The test results indicate that this type of sensor can be used to accurately determine the load prior to failure within 15 percent of the measured value. The second sensor component consists of fiber Bragg grating sensors. The sensors were used to monitor the behavior of steel double-lap shear splices tested under tensile loading up to failure. The measurements were used to identify abnormal structural behavior such as epoxy cracking and FRP debonding. Test results were also compared to numerical values obtained from a three dimensional shear-lag model which was developed to predict the sensor response.

    Full Text Available This project work addresses the crucial need to encourage undergraduate civil and environmental engineering students to gain employment skills and training right from the start of their studies so that their overall employability increases; their confidence level in networking with industry and within the workplace increases; and so that they are successfully able to obtain employment after finishing their studies. This initiative is a stepping-stone employability exercise which focuses specifically on first year students to help them engage with industry right from the start of their course. It is proposed that they would gain some realistic work experience both individually and as part of group within a virtual work environment using an action learning approach. The virtual environment used was based on SecondLife, a popular virtual reality programme. A pilot scheme was set up and run at Brunel University during the summer of 2014 using eight self-selecting first year students. The scheme’s outputs were extensively monitored and evaluated to assess its impact on the development of employability skills. This approach may prove a cost effective way of letting students gain an insight into the workplace whilst improving these skills. It may also prove a way for employers to select from a large range of students the best to actually undertake their real work-based internships.

    Full Text Available Environmental and sustainability assessment tools have an important role in moving towards a better world, bringing knowledge and raising awareness. In the architecture and civil engineering sector, these assessment tools help in moving forward to constructions that have less economic, environmental and social impacts. At present, there are numerous assessment tools and methods with different approaches and scopes that have been analyzed in numerous technical reviews. However, there is no agreement about which method should be used for each evaluation case. This research paper synthetically analyzes the main sustainability assessment methods for the construction sector, comparing their strengths and weaknesses in order to present the challenges of the Spanish Integrated Value Model for Sustainability Assessment (MIVES. MIVES is a Multi-Criteria Decision Making method based on the value function concept and the Seminars of experts. Then, this article analyzes MIVES advantages and weak points by going through its methodology and two representative applications. At the end, the area of application of MIVES is described in detail along with the general application cases of the main types of assessment tools and methods.

    2008-01-01

    The civil-engineering work for the construction of the Linac 4 accelerator will start on 22 October on the Mont Citron, the mound just opposite Restaurant No. 2 between the Computer Centre and the PS complex. Initially the work will involve excavating the mound and transporting the spoil to the area in front of Building SM18. This first phase of work will last for about five months until April 2009. The large number of lorries will cause disruption to traffic on the Route Rutherford, part of the Route Einstein and in the transfer tunnel between the two sites. Traffic lights for alternating traffic will be in operation at each end of the tunnel since there is insufficient room for two lorries travelling in opposite directions to use it at the same time. Consequently, users are strongly recommended not to use the tunnel except for transporting equipment between the two sites. Users not transporting equipment are strongly recommended to use Gates A and B. In parallel, a temporary roundabout will be installed ...

    2009-04-01

    The paper describes an experiment which took place in Iasi town, Romania, consisted in two different topographical survey techniques applied for one and the same objective placed in a block within the city (western part) - a thermal power station. The purpose was to compare those methods and to determine which one is proper to be used in this domain in terms of fastness, optimization and speed of data processing. First technique applied for our survey was the classical one, with a total station. Using the CAD technique, we obtained a final product (a dwg file) and a list of coordinates (a text file). The second method, which we focused our attention more, was the measurement with a very precise 3D laser scanstation, also very suitable in archeology. The data obtained were processed with special software. Result was a 3D model of the thermal power plant composed of measurable cloud point data. Finally, analyzing the advantages and disadvantages of each method, we came to the conclusion that the 3D laser scanning which we used matches well the application, in this case civil engineering, but the future of accepting and implementing this technique is in the hands of Romanian authorities.

    This study is aimed for investigation of fly ash binder with suitable properties for civil engineering needs. The fly ash from Czech brown coal power plant Prunerov II was used and mechanically activated to achieve suitable particle size for alkaline activation of hardening process. This process is driven by dissolution of aluminosilicate content of fly ash and by subsequent development of inorganic polymeric network called geopolymer. Hardening kinetics at 25 and 30 °C were measured by strain controlled small amplitude oscillatory rheometry with strain of 0.01 % and microstructure of hardened binder was evaluated by scanning electron microscopy. Strength development of hardened binder was investigated according to compressional and flexural strength for a period of 180 days. Our investigation finds out, that mechanically activated fly ash can be comparable to metakaolin geopolymers, according to setting time and mechanical parameters even at room temperature curing. Moreover, on the bases of long time strength development, achieved compressional strength of 134.5 after 180 days is comparable to performance of high grade Portland cement concretes.

  16. Development and evaluation of a long range image-based monitoring system for civil engineering structures

    Science.gov (United States)

    Ehrhart, Matthias; Lienhart, Werner

    2015-04-01

    Today, many large-scale civil engineering structures are permanently monitored to provide early warnings and to initiate counter actions from structural failure. Total station measurements are commonly used to determine 3D movements of selected points with measurement intervals of several minutes or hours. However, these measurements do not provide information on the vibration behavior of the structures. For this purpose, other sensors like accelerometers have to be installed on the object. In this paper, we present a monitoring system based on a state of the art image assisted total station (IATS) suitable for the measurement of absolute 3D coordinates and the determination of the structure's natural frequencies. The 3D coordinates can be determined with an accuracy of a few millimeters using conventional total station measurements. For analyzing the structure's natural frequencies, the telescope camera of the IATS is used in combination with dedicated image processing techniques optimized for artificial and natural targets. While the determination of 3D coordinates based on total station measurements is common practice, the idea of using the total station's image data for frequency analysis is new. Consequently, investigations on the achievable performance are pending for commercially available products. We therefore evaluate the potential of this technique at a life-size footbridge by comparison with accelerometer measurements. We demonstrate that with our developed monitoring concept and state of the art hardware, accelerometer measurements can be replaced in several monitoring situations by IATS measurements and image processing techniques.

    Full Text Available The objective of this research is to present and support the implementation of a teaching methodology based on active learning in a programming course taught to students of the first year of the civil engineering career. The active learning techniques used are project-based learning and collaborative learning. The research methodology is the study of three cases. The application of this methodology is supported by the increase in the percentages of achievement of the learning results obtained by the students of the same course in which this methodology was implemented (academic year 2015, to the detriment of students where a traditional methodology of teaching was applied (academic year 2013-2014. To evaluate the achievement, formative and summative evaluations were used by the teaching staff (heteroevaluation, and a self-assessment was implemented at the end of the course as well. From the obtained results it is evident that, when applying an active methodology, the students increase their achievement in each learning result; they reduce the gap between their perception of what is learned and the evaluation of teachers; and they improve their attitudinal skills (self-learning, teamwork, development and presentation of reports, among other benefits.

    2014-01-01

    Full Text Available Nowadays, software artifacts are ubiquitous in our lives being an essential part of home appliances, cars, cell phones, and even in more critical activities like aeronautics and health sciences. In this context software failures may produce enormous losses, either economical or, in the worst case, in human lives. Software analysis is an area in software engineering concerned with the application of diverse techniques in order to prove the absence of errors in software pieces. In many cases different analysis techniques are applied by following specific methodological combinations that ensure better results. These interactions between tools are usually carried out at the user level and it is not supported by the tools. In this work we present HeteroGenius, a framework conceived to develop tools that allow users to perform hybrid analysis of heterogeneous software specifications. HeteroGenius was designed prioritising the possibility of adding new specification languages and analysis tools and enabling a synergic relation of the techniques under a graphical interface satisfying several well-known usability enhancement criteria. As a case-study we implemented the functionality of Dynamite on top of HeteroGenius.

    The application of non-destructive testing and evaluation (NDT/NDE) methodologies in civil engineering has raised a growing interest during the last years because of its potential impact in several different scenarios. As a consequence, Ground Penetrating Radar (GPR) technologies have been widely adopted as an instrument for the inspection of the structural stability of buildings and for the detection of cracks and voids. In this framework, the development and validation of GPR algorithms and methodologies represents one of the most active research areas within the ELEDIA Research Center of the University of Trento. More in detail, great efforts have been devoted towards the development of inversion techniques based on the integration of deterministic and stochastic search algorithms with multi-focusing strategies. These approaches proved to be effective in mitigating the effects of both nonlinearity and ill-posedness of microwave imaging problems, which represent the well-known issues arising in GPR inverse scattering formulations. More in detail, a regularized multi-resolution approach based on the Inexact Newton Method (INM) has been recently applied to subsurface prospecting, showing a remarkable advantage over a single-resolution implementation [1]. Moreover, the use of multi-frequency or frequency-hopping strategies to exploit the information coming from GPR data collected in time domain and transformed into its frequency components has been proposed as well. In this framework, the effectiveness of the multi-resolution multi-frequency techniques has been proven on synthetic data generated with numerical models such as GprMax [2]. The application of inversion algorithms based on Bayesian Compressive Sampling (BCS) [3][4] to GPR is currently under investigation, as well, in order to exploit their capability to provide satisfactory reconstructions in presence of single and multiple sparse scatterers [3][4]. Furthermore, multi-scaling approaches exploiting level

    Many consulting assignments undertaken by Oxand within the framework of life-cycle management of existing nuclear civil engineering structures, relied on taking into account the structure's level of deterioration, the quantitative estimate of its residual strength capacity and the future progression of this capacity over time. The developments of structure assessment techniques allow more and more the integration of the real state of the existing structure by enhancing the value of measures and investigations carried out on structures. On one hand, this information allows to take into account the structure's ageing and therefore estimate the residual resistance and reliability. On the other hand, by investigating the real properties of the structure and of its operation, refined calculations can sometimes highlight a resistance margin of the structure 'such as built' higher than the one considered during design. The precision on the 'real' reliability of the structure allows to refine its management and thus to optimize the infrastructure's performance. Developments of assessment methods are increasingly oriented toward probabilistic approaches. Although they go out of the 'classical regulatory' framework, they bring precision on the 'real' reliability of the structure. Using higher assessment levels needs to have more important and precise input data, what can lead to the need to carry out more detailed investigations. However, these methods offer interesting ways, which can provide, in certain cases, useful additional information for the decision-making of actions to be engaged. The methodology is illustrated with the case of a network of reinforced concrete beams, which are subjected to a rapid increase in their mechanical stresses. In particular this example shows that investigations on the real performances of materials can provided a significant contribution in managing the risks of unavailability

    Full Text Available Introduction: Ludwig van Beethoven, one of the greatest composers in History, was tormented for his whole life by a progressive deafness without definitive diagnosis. Many authors published studies about the etiologic possibilities of the deafness of the music genius with different explanations about his auditory loss. In this work, the author discusses the implications of Beethoven's progressive deafness to the creation of his word, as well as etiologic assumptions of his disease. Would Beethoven have had the same ingeniousness he showed in his symphonies if he did not have hypacusis and tinnitus? What is the influence of his deafness on his work and life? Could he have had a more precise diagnosis and specially a treatment nowadays? Would we have the brilliant composer if he had deafness today? We surely could not have!

    Concrete Non Destructive Characterisation is one of the important issues to evaluate the life duration in the present and future civil engineering structures. The damaging modes of the structures often imply the phases of the appearance and after growth of the cracks. We have to detect, identify and characterize them. The characterization result must lead to a diagnosis of the criticality of a crack regarding to the integrity of the structure and its ability to fulfill its function. The Non Destructive Evaluation techniques are numerous but the ultrasonic ones are able to give an answer to both the characterization and the follow-up of the defect on site. Yet if this method is potentially relevant to detect and identify the cracks in the concrete, we have today a certain amount of locks to remove in order to offer robust and reproducible industrial solutions. These locks range from research points like the description of the real propagation of linear or non linear ultrasonic waves in a heterogeneous material, to more industrial concepts such as the development of devices designed to be applied in the concrete control. For this purpose, we present our latest works on this topic. We develop an overview of the problem: first, to extract the most important theoretical solutions to analyse an unstopping and closed crack in concrete with an only one face access. Then we suggest a methodology to apply one of these solutions on site. A first step of this work after having chosen a solution is to check the ability of the technique to detect a crack, and its sensitivity to the length, depth and opening of the crack. We have developed an experimental plan based on theoretical concept to compare the linear and non linear survey on a set of specimens composed of concrete beams cracked to different depths. We describe the devices and give the latest results. The non linear technique is able to extract information on the size of the cracks. It is an important step to progress in

    Full Text Available Geosynthetics is the term used to describe a range of generally polymeric products used to solve some civil engineeringproblems. The term is generally regarded to encompass eight main product categories: geotextiles, geogrids, geonets,geomembranes, geosynthetic clay liners, geofoam, geocells (cellular confinement and geocomposites. The syntheticpolymeric nature of these products makes them suitable for use in the ground where high levels of durability arerequired. Not only because, properly formulated, they can also be used in exposed applications. Geosynthetics areavailable in a wide range of forms and materials, each to suit a slightly different end use. These products have a widerange of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic,and private development applications including roads, airfields, railroads, embankments, retaining structures,reservoirs, canals, dams, erosion control, sediment control, landfill liners, landfill covers, mining, aquaculture andagriculture. The paper presents basic aspects of geotextiles, drainage, geocomposite designissues and technicalsolutions of their use.

    The engineering careers models were diverse in Europe, and are adopting now in Spain the Bolonia process for European Universities. Separated from older Universities, that are in part technically active, Civil Engineering (Caminos, Canales y Puertos) started at end of 18th century in Spain adopting the French models of Upper Schools for state civil servants with exam at entry. After 1800 intense wars, to conserve forest regions Ingenieros de Montes appeared as Upper School, and in 1855 also the Ingenieros Agrónomos to push up related techniques and practices. Other Engineers appeared as Upper Schools but more towards private factories. These ES got all adapted Lower Schools of Ingeniero Tecnico. Recently both grew much in number and evolved, linked also to recognized Professions. Spanish society, into European Community, evolved across year 2000, in part highly well, but with severe discordances, that caused severe youth unemployment with 2008-2011 crisis. With Bolonia process high formal changes step in from 2010-11, accepted with intense adaptation. The Lower Schools are changing towards the Upper Schools, and both that have shifted since 2010-11 various 4-years careers (Grado), some included into the precedent Professions, and diverse Masters. Acceptation of them to get students has started relatively well, and will evolve, and acceptation of new grades for employment in Spain, Europe or outside will be essential. Each Grado has now quite rigid curricula and programs, MOODLE was introduced to connect pupils, some specific uses of Personal Computers are taught in each subject. Escuela de Agronomos centre, reorganized with its old name in its precedent buildings at entrance of Campus Moncloa, offers Grados of Agronomic Engineering and Science for various public and private activities for agriculture, Alimentary Engineering for alimentary activities and control, Agro-Environmental Engineering more related to environment activities, and in part Biotechnology also

  20. The Making of a Genius: Richard P. Feynman

    2012-01-01

    In 1965 the Nobel Foundation honored Sin-Itiro Tomonaga, Julian Schwinger, and Richard Feynman for their fundamental work in quantum electrodynamics and the consequences for the physics of elementary particles. In contrast to both of his colleagues only Richard Feynman appeared as a genius before the public. In his autobiographies he managed to connect his behavior, which contradicted several social and scientific norms, with the American myth of the "practical man". This connection led to the image of a common American with extraordinary scientific abilities and contributed extensively to enhance the image of Feynman as genius in the public opinion. Is this image resulting from Feynman's autobiographies in accordance with historical facts? This question is the starting point for a deeper historical analysis that tries to put Feynman and his actions back into historical context. The image of a "genius" appears then as a construct resulting from the public reception of brilliant scientific research.

    This work aims at presenting the main results achieved by Working Group (WG) 1 "Novel Ground Penetrating Radar instrumentation" of the COST (European COoperation in Science and Technology) Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar" (www.cost.eu, www.GPRadar.eu). The principal goal of the Action, which started in April 2013 and is ending in October 2017, is to exchange and increase scientific-technical knowledge and experience of Ground Penetrating Radar techniques in civil engineering, whilst promoting throughout Europe the effective use of this safe non-destructive technique. The Action involves more than 300 Members from 28 COST Countries, a Cooperating State, 6 Near Neighbour Countries and 6 International Partner Countries. The most interesting achievements of WG1 include: 1. The state of the art on GPR systems and antennas was composed; merits and limits of current GPR systems in civil engineering applications were highlighted and open issues were identified. 2. The Action investigated the new challenge of inferring mechanical (strength and deformation) properties of flexible pavement from electromagnetic data. A semi-empirical method was developed by an Italian research team and tested over an Italian test site: a good agreement was found between the values measured by using a light falling weight deflectometer (LFWD) and the values estimated by using the proposed semi-empirical method, thereby showing great promises for large-scale mechanical inspections of pavements using GPR. Subsequently, the method was tested on a real scale, on an Italian road in the countryside: again, a good agreement between LFWD and GPR data was achieved. As a third step, the method was tested at larger scale, over three different road sections within the districts of Madrid and Guadalajara, in Spain: GPR surveys were carried out at the speed of traffic for a total of 39 kilometers, approximately; results were collected by using different GPR antennas

    The aim of this study was to use the Hiroshima University - Dental Behavioral Inventory (HU-DBI) to compare oral health attitudes and behavior of dental and civil engineering students in Colombia. The HU-DBI's survey consisting of twenty dichotomous responses (agree-disagree) regarding tooth brushing, was completed at University Antonio Narino for the dental students and the University of Cauca for the civil engineering students. The Spanish version of the HU-DBI questionnaire was taken by 182 of 247 dental students and 411 of 762 engineering students. The data was-statistically analyzed by the chi-square test and backward logistic regression. Compared to the engineering students, the dental students were more likely to agree with questions such as "I am bothered by the color of my gums"(OR = 2.2, 95% CI: 1.3-3.7),"I think I can clean my teeth well without using toothpaste" (OR = 3.0, 95% CI: 1.5-5.9), "I have used a dye to see how clean my teeth are" (OR = 2.9, 95% CI: 1.9-4.3), and "I have had my dentist tell me that I brush very well" (OR = 2.0, 95% CI: 1.3-3.1). The dental education curriculum in a dental school compared to a civil engineering school in Colombia indicated that a three-phase curriculum in didactics and clinics increased oral health attitudes and behavior from entry to graduation.

    2005-01-01

    Stress distribution of holed geotextile cross-section under uniaxial and double-axial tension is analyzed with the boundary element method (BEM). The calculation results indicate that stress distribution of holed geotextile crosssection is greatly related to the dimension of the specimen, the size of the hole, the shape of the hole and the tensile condition, and the stress concentration area of holed geotextile from the side of the hole to 3-4 times of the hole diameter should be strengthened in order to improve quality of the projects. These results could provide guidance for engineering application of geotextiles.

  4. Detecting steel rods and micro-piles: A case history in a civil engineering application

    Science.gov (United States)

    Orlando, Luciana

    2012-06-01

    Investigating engineered structures with GPR is challenging because quite often the scale of important features is similar or smaller that the natural scale of heterogeneity in the material. In this paper I summarize the key factors and use numerical simulations and real data examples to illustrate the tradeoff between detection and resolution. The targets were micro-piles and steel bars with diameters 0.13 m and 0.02 m, respectively, and embedded in an ancient wall that consists of an aggregate of stones ranging in size from 1 cm to half meter, mortar and air. The data were collected with center frequency antennas of 200, 600, 2000 MHz which provide increasing resolution. The model and measurement results indicate that lower resolution may result in a better understanding of the structure imaged with GPR. In fact, high resolution profiles show enhanced anomalies caused by heterogeneities in the host material, making data interpretation more difficult. This study shows that GPR survey design must be clear about the particular engineering objective and requires selecting the optimal frequency and bandwidth depending on the target dimension.

  5. STRATEGY FOR IMPROVEMENT OF SAFETY AND EFFICIENCY OF COMPUTER-AIDED DESIGN ANALYSIS OF CIVIL ENGINEERING STRUCTURES ON THE BASIS OF THE SYSTEM APPROACH

    Directory of Open Access Journals (Sweden)

    Zaikin Vladimir Genrikhovich

    2012-12-01

    Full Text Available The authors highlight three problems of the age of information technologies and proposes the strategy for their resolution in relation to the computer-aided design of civil engineering structures. The authors express their concerns in respect of globalization of software programmes designated for the analysis of civil engineering structures and employed outside of Russia. The problem of the poor quality of the input data has reached Russia. Lately, the rate of accidents of buildings and structures has been growing not only in Russia. Control over efficiency of design projects is hardly performed. This attitude should be changed. Development and introduction of CAD along with the application the efficient methods of projection of behaviour of building structures are in demand. Computer-aided calculations have the function of a logical nucleus, and they need proper control. The system approach to computer-aided calculations and technologies designated for the projection of accidents is formulated by the authors. Two tasks of the system approach and fundamentals of the strategy for its implementation are formulated. The study of cases of negative results of computer-aided design of engineering structures was performed and multi-component design patterns were developed. Conclusions concerning the results of researches aimed at regular and wide-scale implementation of the strategy fundamentals are formulated. Organizational and innovative actions concerning the projected behaviour of civil engineering structures proposed in the strategy are to facilitate: safety and reliability improvement of buildings and structures; saving of building materials and resources; improvement of labour efficiency of designers; modernization and improvement of accuracy of projected behaviour of buildings and building standards; closer ties between civil and building engineering researchers and construction companies; development of competitive environment to boost

  6. CloudGenius: Automated Decision Support for Migrating Multi-Component Enterprise Applications to Clouds

    CERN Document Server

    Menzel, Michael

    2011-01-01

    One of the key problems in migrating multi-component enterprise applications to Clouds is selecting the best mix of VM images and Cloud infrastructure services. A migration process has to ensure that Quality of Service (QoS) requirements are met, while satisfying conflicting selection criteria, e.g. throughput and cost. When selecting Cloud services, application engineers must consider heterogeneous sets of criteria and complex dependencies across multiple layers impossible to resolve manually. To overcome this challenge, we present the generic recommender framework CloudGenius and an implementation that leverage well known multi-criteria decision making technique Analytic Hierarchy Process to automate the selection process based on a model, factors, and QoS requirements related to enterprise applications. In particular, we introduce a structured migration process for multi-component enterprise applications, clearly identify the most important criteria relevant to the selection problem and present a multi-cri...

    The teaching of mathematics is invariably language-based, but spatial-temporal (ST) reasoning (making a mental image and thinking ahead in space and time) is crucial to the understanding of math. Here we report that Big Seed, a demanding ST video game, based upon the mathematics of knot theory and previously applied to understanding DNA structure and function, can be used to reveal innate ST reasoning. Big Seed studies with middle and elementary school children provide strong evidence that ST reasoning ability is not only innate but far exceeds optimistic expectations based on age, the percentage of children achieving exceptional ST performance in less than 7 h of training, and retention of ability.

    A moment tensor inversion (MTI) code originally developed to compute source mechanisms from mining-induced seismicity data is now being used in the laboratory in a civil engineering research environment. Quantitative seismology methods designed for geological environments are being tested with the aim of developing techniques to assess and monitor fracture processes in structural concrete members such as bridge girders. In this paper, we highlight aspects of the MTI_Toolbox programme that make it applicable to performing inversions on acoustic emission (AE) data recorded by networks of uniaxial sensors. The influence of the configuration of a seismic network on the conditioning of the least-squares system and subsequent moment tensor results for a real, 3-D network are compared to a hypothetical 2-D version of the same network. This comparative analysis is undertaken for different cases: for networks consisting entirely of triaxial or uniaxial sensors; for both P and S-waves, and for P-waves only. The aim is to guide the optimal design of sensor configurations where only uniaxial sensors can be installed. Finally, the findings of recent laboratory experiments where the MTI_Toolbox has been applied to a concrete beam test are presented and discussed.

    Full Text Available The purpose of the research is to discover which employability skills may be developed by students from technical universities in order to meet market demands. Since graduates from technical universities face unemployment or over qualification for vacant jobs, we presumed that there is a misalignment between employers’ expectations concerning graduates’ skills and what they really get from school. Therefore, we conceived a questionnaire to see the demands of the business environment regarding graduates’ technical and professional skills. After analyzing the data, we proposed an interdisciplinary module system, where the mentors coming from the companies involved in the study teach voluntary or optional courses and applications in the domains where they have expertise. We used the employability skills model to find that mix of competencies that may help graduates find jobs in their field of knowledge. This innovative method serves universities, students and companies as well: the prestige of a university is quantified by the experts delivered into the labor market; companies will have well prepared employees in their specific area, with less costs; students will find jobs which will match their expectations, giving them motivation to perform. The limitation of the present research is that the study refers only to the Civil Engineering specialization of the Technical University Cluj-Napoca Romania.

  11. Experimental Investigation of the Effects of Reverse Bending and Straightening Process on Carbon Steel Bars used for Civil Engineering Applications

    Adewole, K. K.

    2014-01-01

    Full Text Available This paper presents an experimental investigation of the effects of reverse bending and straightening process on the mechanical properties of a typical carbon steel bar used for civil engineering applications. Twenty four specimens each were used for the metallogarphy, microhardness and tensile tests. The investigation revealed that the reverse bending and straightening process has no significant effect on the bars’ through-thickness microstructure and hardness. However, the reverse bending and straightening process reduces the yield load, ultimate load, and displacement at fracture of the bars by 4.27%, 2.58%, and 18.62% respectively. These results highlight the need to take into consideration the effects of the previous loading history of the bars/wires, particularly the reduction in the displacement at fracture and consequently, the ductility of the bars/wires in the design and fitness for purpose assessment of components made from them, since the bars/wires could experience high strain during installation and in service due to overloads.

  12. Development of Rapid, Continuous Calibration Techniques and Implementation as a Prototype System for Civil Engineering Materials Evaluation

    Until recently, civil engineering material calibration data could only be obtained from material sample cores or via time consuming, stationary calibration measurements in a limited number of locations. Calibration data are used to determine material propagation velocities of electromagnetic waves in test materials for use in layer thickness measurements and subsurface imaging. Limitations these calibration methods impose have been a significant impediment to broader use of nondestructive evaluation methods such as ground-penetrating radar (GPR). In 2006, a new rapid, continuous calibration approach was designed using simulation software to address these measurement limitations during a Federal Highway Administration (FHWA) research and development effort. This continuous calibration method combines a digitally-synthesized step-frequency (SF)-GPR array and a data collection protocol sequence for the common midpoint (CMP) method. Modeling and laboratory test results for various data collection protocols and materials are presented in this paper. The continuous-CMP concept was finally implemented for FHWA in a prototype demonstration system called the Advanced Pavement Evaluation (APE) system in 2009. Data from the continuous-CMP protocol is processed using a semblance/coherency analysis to determine material propagation velocities. Continuously calibrated pavement thicknesses measured with the APE system in 2009 are presented. This method is efficient, accurate, and cost-effective.

  13. Ways of Realization of the Pragmatic Potential of Color Naming "Green" in English Advertising Texts in Civil Engineering Sphere

    2017-03-01

    Full Text Available Color naming is the subject of the representatives of different branches of knowledge – ethnographers, philologists, culture experts, psychologists, political scientists and many other professionals. The ability of color units to transmit values that go beyond the designation of color, is widely used in the literature, in everyday speech, in the advertising field. In recent years, interest has increased in linguistics to the study of color naming in advertising function. The present work is devoted to identifying ways of lexeme nomination «green» in the English-language advertising texts of civil engineering sphere. Most extra-linguistic factors are the cause of changes in the semantic structure of the word. The global environmental crisis, the issue of harmonization of man and nature contribute to the development of relations in this terminological adjective meaning of «environmentally friendly». In the studied texts the following methods of updating the value of «green» are presented: terminologization, varying forms, the creation of a pun. Inclusion in the text of comparatives and superlatives results in deliberate ambiguity statements: on the one hand, it is reported on the benefits of environmentally friendly products, on the other – the color component is updated. Ambiguity of the «green» advertising has a pragmatic focus, it is meant to attract the attention of potential consumers, create a positive image of the product, increase evaluative statements.

    2016-10-01

    The extractive and construction industries rely heavily on accurate geospatial data to control position, location, alignment, and orientation of planned excavations. Recent advancements in the survey industry, through the use of terrestrial laser scanning, can now provide engineering teams with three-dimensional (3-D) data in unprecedented detail via georeferenced point clouds. Furthermore, equipment is now available that provides fully mobile automated mapping solutions, independent of satellite positioning, utilizing simultaneous localization and mapping. This paper evaluates the surveying capability of three fully mobile automated mapping solutions against a benchmark laser scanning survey undertaken at the underground Camborne School of Mines Test Mine facility. The study highlights that handheld automated mapping solutions, in which closed-loops can be formed, have the potential to provide quicker data collection and processing time, as well as the required accuracy for underground surveying applications. However, the automated solution was unable to produce the necessary point cloud density to identify low-angled discontinuities that may have a major safety implication, leading to potential rockfall.

    2015-09-01

    This article examines the application of knowledge creation learning and innovation to higher education in construction. The objectives are to demonstrate the application of the course based on knowledge creation learning to mass teaching and to analyse whether knowledge creation learning improves student motivation and learning. The empirical data (n = 120) consist of the results of a student survey from two university-level courses. The first course, Basics of Construction Management and Economics (n = 79), was developed on the basis of knowledge creation, and the second course, Building Project (n = 41), was implemented using the case-based learning method. The results, based on student self-assessments, showed that case-based learning supported the learning process more effectively than did the course based on knowledge creation. On the other hand, the results showed the relevance of applying knowledge creation-based learning to the mass teaching of construction in higher education. The findings of this empirical study suggest that more attention should focus on developing students' metacognitive skills in engineering education.

  2. Energy evaluation on bounded nonlinear control laws for civil engineering applications

    In the last decades researchers in the field of structural engineering have challenged the idea of facing natural hazard mitigation problems by adding to structures particular systems which are designed to protect buildings, bridges and other facilities from the damaging effects of destructive environmental actions. Among most protective systems and devices, active structural control, although having already reached the stage of full-implemented systems, still need theoretical investigation to achieve a complete exploitation of its capacity in reducing structural vibrations. In most of the operating systems (e.g. Soong and Reinhorn, 1993), linear control laws based on some quadratic performance function criteria are used since the design process for these linear strategies are fully developed and investigated. Moreover, the performances of structural systems controlled by linear techniques bring about some question concerning the complete and wise utilization of the capacity of control devices. Indeed, some of these inefficiencies are evident such as the inability to produce a significant peak response reduction in the first cycles of recorded or simulated time histories. (e.g. Reinhorn et al., 1993). Realizing that the expected maximum value for the required control force is a fundamental parameter in all processes to design the complete control system, in this paper it is shown that appropriate nonlinear control laws can significantly enhance the reduction of the system response under the same constraints imposed on the control force. Energy evaluation on the performance of different kinds of nonlinearities are reported such that a common base is built to perform comparative studies. These techniques have been successfully experimented on a structural model with ground excitations supplied by shaking table (e.g. Gattulli et al., 1994).

    Alexis Carrel was a Frenchman from Lyon, who gained fame at the Rockefeller Institute in New York at the beginning of the 20th century. He was the first to demonstrate that arteriovenous anastomoses were possible. Alexis Carrel was awarded the Nobel Prize for his contributions to vascular surgery and transplantation in 1912. He was a versatile scientist, who made numerous discoveries from the design of an antiseptic solution to treat injuries during the First World War to tissue culture and engineering, and organ preservation, making him the father of solid organ transplantation. Together, with the famous aviator and engineer Charles Lindbergh, they were the first scientists capable of keeping an entire organ alive outside of the body, using a perfusion machine. Due to his many dubious ideas and his association with fascism in the 1930s and during the Second World War, many of his scientific achievements have been forgotten today and taken for granted.

    In recent years, significant advances have been made in business organization and management. The growing demands of clients as well as the globalization of world markets are among the many factors that have led to the establishment of systems of quality control and environmental management as a competitive strategy for businesses. When compared to other professional sectors, the construction sector has been slower to respond to environmental problems and to adopt Environmental Management Systems (EMS). In the world today the ISO 14001 standard is currently the main frame of reference used by construction companies to implement this type of management system. This article presents the results of a general study regarding the evaluation of the application of the ISO 14001 standard at civil engineering construction worksites in the Community of Madrid (Spain), specifically pertaining to requirement 4.4.1, Resources, roles, responsibilities, and authority. According to requirement 4.4.1, company executives should appoint people responsible for implementing the EMS and also specify their responsibilities and functions. The personnel designated for supervising environmental work should also have sufficient authority to establish and maintain the EMS. The results obtained were the following: - EMS supervisors did not generally possess adequate training and solid experience in construction work and in the environment. Furthermore, supervisors were usually forced to combine their environmental work with other tasks, which made their job even more difficult. - Generally speaking, supervisors were not given sufficient authority and autonomy because productivity at the construction site had priority over environmental management. This was due to the fact that the company management did not have a respectful attitude toward the environment, nor was the management actively involved in the establishment of the EMS. - Insufficient resources were allocated to the Environmental

    In this research, survey of awareness and attitude to high level radioactive waste (HLW) disposal on 36 students of a postgraduate course was conducted. They have been studying civil and rock engineering, so they belong to 'the Group' that acquires high education, culture and faculty to understand the science in geological disposal of HLW. First of all the awareness of danger or safety to HLW disposal was examined. Some 23% regard HLW disposal as safe, on the contrary 60% feel danger. This is similar to the awareness of the average public. And some 72% think that HLW should be disposal, but only 6% agree the repository in their town. It shows that the Group of high education has a tendency of calmly understand the necessity of disposal, but they also have a nature so-called 'not in my back yard (NIMBY)'. After that, the students were divided in two groups. Then, one group received information from the promoter, and another received information from opponents. The result of second questionnaire shows that the awareness of danger is affected strongly by given information even in this Group, but they become thoughtful and prudent in their opinion and decision-making as increasing information.

    2014-10-01

    Full Text Available The understanding of creativity in the social sciencies became more complex with the course of time. The concepts of creative individual, creative process and environment are discussed. Looking at the environment, distinction was made on three levels: macro, meso and micro. The impact of environments on creativity is analyzed, focusing attention on the collective creativity as the positive micro-environmental factor for innovations. Insights are gained about the tendency to move from an exclusive, elite, narrow concept of creativity, measured by the creation of products and their abundance, towards a broader, democratic concept of everyday creativity of the most people. The conclusion is that the creative industries of the exceptional creativity of genius or talent and mysticism are gradually transformed to broader creativity as the governed system, emphasizing creativity links with internal elements of the system and with the social context.

    2010-01-01

    Peter Watson's virtuoso sweep through modern German thought and culture, from 1750 to the present day, will challenge and confound both the stereotypes the world has of Germany and those that Germany has of itself. From the end of the Baroque era and the death of Bach to the rise of Hitler in 1933, Germany was transformed from a poor relation among Western nations into a dominant intellectual and cultural force—more creative and influential than France, Britain, Italy, Holland, and the United States. In the early decades of the twentieth century, German artists, writers, scholars, philosophers, scientists, and engineers were leading their freshly unified country to new and unimagined heights. By 1933, Germans had won more Nobel Prizes than any other nationals, and more than the British and Americans combined. Yet this remarkable genius was cut down in its prime by Adolf Hitler and his disastrous Third Reich—a brutal legacy that has overshadowed the nation's achievements ever since. How did the Germans t...

    Producers, authorities and users have acknowledged the need for common environmental guidelines for residues. The objective of this project has been to develop a proposal for common environmental guidelines for reuse of ash in civil engineering applications. The project has a narrow risk assessment perspective and focus on a set of substances where a well developed environmental policy and knowledge are available. Health aspects for construction workers are not covered in the project. The starting point in the risk assessment is the assumption that ashes may be used just like any conventional construction material. Special requirements or regulations regarding precautionary actions in the handling of ashes, regarding the site or surroundings will be avoided. The guiding principle has been the precautionary principle: reuse of ash is acceptable only if it constitute an insignificant risk to health and environment. The calculations are based on defined emission- and exposure scenarios. The concept of insignificant risk imply that the impact in the defined points of compliance does not exceed established health- and environmental criteria. The model address health risks associated with spreading of particles and exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries and consumption of ground water. Off-site environmental effects in surface waters and in soil as well as health- and environmental risks in the post use phase are also considered. Exposure by dust is addressed in the same way as in the Swedish Environmental Protection Agency's guidelines for contaminated soil. The guidelines values for exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries are total content, whereas the guidelines for exposure by consumption of ground water or environmental effects in surface waters are based on leaching properties of the ash. The guidelines rely on a conceptual model, defined emissions and

    Nowadays, Touro amphibolites (La Coruna, Spain) are exploited as crushed-rock aggregates in civil engineering. These materials are mainly used as ballast for road construction. Therefore, it is interesting to study these materials in function of several parameters obtained directly in quarry faces. For this purpose, the same techniques and tests previously applied in other fields such as natural stone have been used. The aim of this work is to study the quality and durability of Touro amphibolites when subjected to extreme temperature, water and salt (NaCl) actions. The NaCl is included in this study because it is commonly used as fluxing material in pavements and roads. The quality of these amphibolites, a classification based on the concrete and road tests and the techniques applied, is good. The best properties of these materials are their low porosity and high ability to compact. They also have a high durability under the action of extreme temperatures, salts and water. These results also indicate that these amphibolites can better support high temperature rather than low temperature degradation. (Author)

  10. Modeling In-Use Steel Stock in China’s Buildings and Civil Engineering Infrastructure Using Time-Series of DMSP/OLS Nighttime Lights

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available China’s rapid urbanization has led to increasing steel consumption for buildings and civil engineering infrastructure. The in-use steel stock in the same is considered to be closely related to social welfare and urban metabolism. Traditional approaches for determining the in-use steel stock are labor-intensive and time-consuming processes and always hindered by the availability of statistical data. To address this issue, this study proposed the use of long-term nighttime lights as a proxy to effectively estimate in-use steel stock for buildings (IUSSB and civil engineering infrastructure (IUSSCE at the provincial level in China. Significant relationships between nighttime lights versus IUSSB and IUSSCE were observed for provincial variables in a single year, as well as for time series variables of a single province. However, these relationships were found to differ among provinces (referred to as “inter-individual differences” and with time (referred to as “temporal differences”. Panel regression models were therefore proposed to estimate IUSSB and IUSSCE in consideration of the temporal and inter-individual differences based on a dataset covering 1992–2007. These models were validated using data for 2008, and the results showed good estimation for both IUSSB and IUSSCE. The proposed approach can be used to easily monitor the dynamic of IUSSB and IUSSCE in China. This should be critical in providing valuable information for policy making regarding regional development of buildings and infrastructure, sustainable urban resource management, and cross-boundary material recycling.

    1997-01-01

    The recent results from the HEIDELBERG-MOSCOW experiment have demonstrated the large potential of double beta decay to search for new physics beyond the Standard Model. To increase by a major step the present sensitivity for double beta decay and dark matter search much bigger source strengths and much lower backgrounds are needed than used in experiments under operation at present or under construction. We present here a study of a project proposed recently, which would operate one ton of 'naked' enriched GErmanium-detectors in liquid NItrogen as shielding in an Underground Setup (GENIUS). It improves the sensitivity to neutrino masses to 0.01 eV. A ten ton version would probe neutrino masses even down to 10^-3 eV. The first version would allow to test the atmospheric neutrino problem, the second at least part of the solar neutrino problem. Both versions would allow in addition significant contributions to testing several classes of GUT models. These are especially tests of R-parity breaking supersymmetry mo...

    Scientist. Innovator. Rebel. For decades, Freeman Dyson has been regarded as one of the world’s most important thinkers. The Atlantic wrote, “In the range of his genius, Freeman Dyson is heir to Einstein – a visionary who has reshaped thinking in fields from math to astrophysics to medicine, and who has conceived nuclear-propelled spaceships designed to transport human colonists to distance planets.” Salon.com says that, “what sets Dyson apart among an elite group of scientists is the conscience and compassion he brings to his work.” Now, in this first complete biography of Dyson, author Phillip F. Schewe examines the life of a man whose accomplishments have shaped our world in many ways. From quantum physics to national defense, from space to biotechnology, Dyson’s work has cemented his position as a man whose influence goes far beyond the field of theoretical physics. It even won him the million dollar Templeton prize for his writing about science and religion. Recently, Dyson has made head...

    Directory of Open Access Journals (Sweden)

    Aleksandr Vladimirovich Lugovtsov

    2012-09-01

    Full Text Available The non-governmental industrial sector of Russia is growing from year to year as a result of privatization program consistently held by the government. In the beginning of the 90-s, the heads of state have decided not to hold the state industrial policy any more reasoning from the idea of market self-regulation. The enterprises of the military-industrial complex of Russia, as a result, were in a grave condition because there were no state orders anymore. The enterprises were offered to produce civil engineering production because it was considered that there were no more enemies to fight against. As time goes by, some enterprises became bankrupt. But the majority has survived under the direction of smart owners despite but not due to the conditions of survival of that time. The life has shown that the state industrial policy is indispensable, especially when Russia is near to enter into the WTO. There are no more obstacles on the path to this, but nobody knowsexactly which enterprises will become bankrupt, what will be with those people who will lose their work and which enterprises will continue working and how. It is not clear neither at federal level nor at regional or municipal. In this paper, the modern operating conditions and opportunities to modernize the non-governmental industrial sector are analyzed. Performatives on education reform regarding the young engineers and economists aimed to reduce the period of their adaptation at work have been formulated.

  15. Problems Related to the Siting of the Laboratory Building for Civil Engineering Department at the University of Warmia and Mazury in Olsztyn, Poland

    Zagroba, Marek

    2016-10-01

    This paper deals with the conditions underlying and the problems arising from the siting of a building with specialist laboratories in a developed part of the university campus in Olsztyn, Poland. The topography of the terrain and the need to house civil engineering laboratories in the planned building had an immense impact on the shape of the building and consequently on its foundations, whose dimensions responded to the ground conditions and the specification of various loads they would have to support, including the equipment for the laboratories. The siting of a building as a step in the construction process entails several problems, which are first taken into consideration at the stage of making preliminary concept plans and are subsequently verified while working on the final construction plan. The required information included geotechnical documentation, survey of the ground conditions and the data regarding the predicted loads on the building, necessary to select the right type of foundations. All these problems grow in importance when dealing with such unique buildings like the discussed example of a laboratory building for the Civil Engineering Department, built on a site within a conservation zone on the campus of the University of Warmia and Mazury in Olsztyn, Poland. The specific character of the building and the specialist equipment with which it was to be furnished (a resistance testing machine, a 17-meter-long wave flume) necessitated a series of analyses prior to the siting of the building and selecting suitable foundations. In turn, the fact that the new building was to be erected in the conservation zone meant that collaboration with the Heritage Conservation Office had to be undertaken at the stage of making the plan and continued during the construction works. The Heritage Officer's recommendations concerning the building's shape, divisions, dimensions, materials used, etc., created a situation where the team of designers and architects had to

  16. Factors that Influence Female Folk to engage in Building and Civil Engineering Construction Site Work in Nigeria – a case Study of Isoko Women

    Directory of Open Access Journals (Sweden)

    O. Osubor (Fniqs, Rqs

    2016-11-01

    Full Text Available From early times, building and civil engineering construction has been a male dominated industry. But in today’s contemporary times, the women folk have broken this monotony of male domination. This is evident in the building and engineering industry. Isoko land in the south of Delta State, although women have broken from the stereotype of home keeping into construction, their level of engagement is at the lowest ebb as casual and unskilled workers. This study looks at the factors that encourage female to engage in construction especially at the lowest ebb and the implications for the woman, society, and construction industry. Oral interview methodology was adopted in this study. The response of five local contractors/employers and 60 women interviewed at construction site formed the data for this study. A simple percentage was used to analyze data generated. Findings reveal that poverty and unemployment, lack of education and skill, family responsibility and environmental factors top the reasons. Policies that encourage and make it mandatory for women to progress in education and skill acquisition, provide a future for women in construction and stop discrimination against women will be a step in the right direction. Such policies are recommended.

  5. The Avant-Gardist, the Male Genius and the Proprietor

    Directory of Open Access Journals (Sweden)

    2007-05-01

    Full Text Available As the title suggests, this article will deal not only with the avant-garde and the romantic idea of geniality but also with the much more mundane concept of literary property. Even though the law might seem alien to the lofty ideals of the avant-garde artist, the construction of the creative genius and the birth of copyright will eventually prove to be quite closely connected. But before I move on to the legal part I would like to start with the essentials: with the author, or the artist. The American artist John de Andreas sculpture The Artist and his model from 1980 is probably one of the most revealing pictures of the avant-gardist selfconception ever made. This is a picture of the artist at work, but I will argue it can also be regarded as a legal character. What meets the eye is however very far from the law as we know it. de Andreas sculpture is a self-portrait of the artist at work: a highly naturalistic full-scale portrait of two people. One of them is a naked woman, resting casually on a white socket and looking down on the other who is a fully dressed man. As the title clearly states, the sculpture depicts the classical relation between The Artist and his Model, and it is no coincidence that the artist has a male pronoun and the model a female body. The roles of the artist and his model are traditional stereotypes which we can find in most books on art history - one is an artist and the other is a model; one is a man and the other is a woman; one is dressed and the other one is undressed.

  6. Muslim Genius; Ibn Sina’s Effects on Cardiology

    Sabri Onur Caglar

    2014-10-01

    Full Text Available  Ibn Sina (980-1037 was born in the village of Afshana, near Bukhara. Ibn Sina received his early education in his town and by the age of 10 he became a Quran Hafiz. He had exceptional intellectual skills. In some of his teenage years he lived in Anatolia. At the age of sixteen he dedicated all his efforts to learn medicine and when he was eighteen, he gained the status of a reputed physician. His synthesis of Islamic medicine, al Qanun reputed physician fi’l tibb (The Canon of Medicine, was the final authority on medical problems in the world for several centuries. His most significant medical works are the Qanun (Canon and a thesis on cardiac drugs”. The Canon of Medicine (Qanun: Law of Medicine is one of the most famous books in the history of medicine. This book is a five volume medical encyclopedia that was completed in 1025. The eleventh section of the third book primarily deals with different kinds of heart diseases, their effects, and treatment. It should be remembered that the Canon of Avicenna was written in early 11th century and it should be reviewed in the light of the state of knowledge concerning heart diseases and their treatment attained at that time. Researchers today have the advantage of highly advanced instruments which were not available to Ibn Sina 1000 years ago. That he wrote this section of the Canon in such detail and compiled a separate thesis on heart drugs are enough to prove that he had a clear understanding of the fatal character of heart diseases. He was a really scientific genius and medical practitioner. About 1000 years ago, he created many medical hypotheses and tried to discover unknown things related with humanity. Especially anatolian muslim researchers have to follow this way if they want to be succeeded or add some fantastic discoveries on science.

    2013-11-01

    Many fluids lab facilities and their associated student experiences were built back in the 1960-1970 time frames. They typically consisted of large facilities that included wind tunnels, flumes, wet wells, pump stations, etc. Today these labs are physically and pedagogically out dated and the need for lab space is forcing the closing of large scale labs. This is the same basic problem within the Swanson School of Engineering at the University of Pittsburgh. Thus we have replaced all the old equipment and lab experiences with small bench top experiments with a focus on applying the large body of knowledge associate with better student learning experiences. This paper will describe the concepts behind the design of the new experiments and the learning improvements discovered as a result of moving from a few large experiments to a larger number of smaller scale experiments.

    The aim of this research was to present a pilot plant for the treatment of stormwater sediments and to compare the decontamination rate to that obtained by landfarming. The possibilities for reuse of the treated sediments in civil engineering are also studied. Four sediments from retention/infiltration ponds or from street sweeping were studied. In each case organic matter (OM), total hydrocarbons (TH) and polycyclic aromatic hydrocarbons (PAH) were measured. Geotechnical tests were carried out to evaluate the reuse possibilities of the treated sediments. Treatment by means of the pilot plant was efficient at reducing TH and PAH concentrations: THs were reduced by 53-97% and PAHs were decreased by 60-95%. By comparison, a reduction of 45-75% in TH concentration is obtained with landfarming, whereas there is no significant decrease in PAHs. Furthermore, geotechnical tests showed that the treated fractions from the pilot plant can be reused as road embankments and as a capping layer. These results are most encouraging and show that stormwater sediments can valuably be reused after treatment in a pilot plant. Landfarming is less efficient but this technique could be used as a pretreatment in the case of high TH pollution.

    áticos Abstract The latest amendments to the Law on Higher Education strengthened the role and importance of cooperation between the universities and socio-economic environment. The idea of curriculum based on learning outcomes should facilitate cooperation of universities with external stakeholders (e.g. employers, representatives of professional organizations in the process of educational offer development. The employers expect graduates to have a high level of competence that are a synthesis of theoretical knowledge, practical skills and personal features. In their opinion, the role of the education system is to  prepare  graduates practically for the profession and to provide them with a wide array of professional skills. Most frequently mentioned weakness of university graduates is the lack of experience and practical skills. Initially, the participation of employers in curriculum design was symbolic. It was the result of lack of interest or the requirement for graduates for very specific skills needed for a given position in the company. The participation of employers in the curriculum design and evaluation of its quality has increased since the representatives of employers were included in the external evaluation committees. The most effective forms of employers' participation in creating a curriculum of study e.g. dual study, common post-graduate study, internships, technical trips, dedicated lectures etc. were discussed on the basis of civil engineering in technical university. The participation of employers is increasingly more conscious. However, there is still a need to seek mechanisms and methods for consulting that would really involve employers into cooperation, and at the same time would not generate more red tape on any side.

The research data were then analyzed by statistics and non-metric dimensional scaling method. The results showed that these students had positively patriotism and national pride, and were very interested in society, politics, science progresses and life meanings with the similar understandings or opinions. Happy family was the primary life goal only followed by career success for the most students. The relationships among 10 basic values defined by Schwartz were much different for students with different majors, genders, residences before college life,consumptions,provinces,one-child or multi-child families, which indicated those factors have some impact on the values of the students. For the whole sample, 10 basic values of civil engineering students newly graduated from university had the characteristics of clustering. Hedonism and power were negatively related to the other values,and the distribution of achievement value was much different from the structural relationship proposed by Schwartz and testified by many other overseas researches, which might be attributed to the deferent understandings of achievement between the Eastern culture and Western culture. The methods and results could be referred to the research and education for college students.%选择北京大学国情研究中心编制的《2007年全国公民价值观状况调查问卷》[8]中的部分问题,采用问卷调查的方法,对436名2011届土建类部分专业的大学毕业生进行价值观调查.对调研数据采用数理统计和多尺度降维方法进行相关性分析.结果表明:土建类毕业生大多具有较高的爱国热情和民族自豪感,对社会、政治、科技进步和人

    This work aims at presenting the ongoing research activities carried out in Working Group 1 'Novel GPR instrumentation' of the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (www.GPRadar.eu). The principal goal of the COST Action TU1208 is to exchange and increase scientific-technical knowledge and experience of GPR techniques in civil engineering, simultaneously promoting throughout Europe the effective use of this safe and non-destructive technique in the monitoring of infrastructures and structures. Working Group 1 (WG1) of the Action focuses on the development of innovative GPR equipment dedicated for civil engineering applications. It includes three Projects. Project 1.1 is focused on the 'Design, realisation and optimisation of innovative GPR equipment for the monitoring of critical transport infrastructures and buildings, and for the sensing of underground utilities and voids.' Project 1.2 is concerned with the 'Development and definition of advanced testing, calibration and stability procedures and protocols, for GPR equipment.' Project 1.3 deals with the 'Design, modelling and optimisation of GPR antennas.' During the first year of the Action, WG1 Members coordinated between themselves to address the state of the art and open problems in the scientific fields identified by the above-mentioned Projects [1, 2]. In carrying our this work, the WG1 strongly benefited from the participation of IDS Ingegneria dei Sistemi, one of the biggest GPR manufacturers, as well as from the contribution of external experts as David J. Daniels and Erica Utsi, sharing with the Action Members their wide experience on GPR technology and methodology (First General Meeting, July 2013). The synergy with WG2 and WG4 of the Action was useful for a deep understanding of the problems, merits and limits of available GPR equipment, as well as to discuss how to quantify the reliability of GPR results.

  16. GENIUS: A tool for multi-disciplinary and multi-scalar databases

    2013-12-01

    Cities are responsible for the majority of energy consumption on the planet. As a consequence, researches regarding energy use in urban context have been increasing for the last decades. Recently the interrelationship between city, energy consumption and urban microclimate appeared as a key component of urban sustainability. To be accurate, those studies must take into account a multidisciplinary urban context and modelling tools need high definition data. Nevertheless, at the city scale, input data is either imprecise or only available for small areas. In particular, there is a lack of information about buildings footprints, roofs sloping, envelope materials, etc. Moreover, the existing data do not allow researchers to explore prospective issues such as climate change or future urban development. In this sense, we developed a new tool called GENIUS (GENerator of Interactive Urban blockS) to build high definition and evolutionary maps from available databases. GENIUS creates maps composed of archetypical neighbourhood coming as shape-files of polygons with additional information (height, age, use, thermal insulation, etc.). Those archetypical neighbourhoods come to seven types of urban blocks that can be found in most European cities. Those types can be compared with Stewart and Oke Local Climate Zones (LCZ). The first step of our method is to transform an existing map into an 'archetypical map'. To do this, the urban database of the IGN (French Geographical Institute) was used. The maps were divided into cells of 250 meters resolution. For each cell, about 40 morphological indicators were calculated. Seven groups of blocks were then identified by means of Principal Component Analysis. GENIUS databases are also able to evolve through time. As a matter of fact, the initial map is transformed, year after year, by taking into account changes in density and urban history. In that sense, GENIUS communicates with NEDUM, a model developed by the CIRED (International

  12. Music, musicians, and the brain: an exploration of musical genius. The 2004 presidential address.

    Science.gov (United States)

    Popp, A John

    2004-12-01

    The concept of musical genius used to frame a discussion of the "art" practiced by neurosurgeons is the focus of the 2004 Presidential Address to the American Association of Neurological Surgeons (AANS). The musical genius, in contrast to the musically talented individual, is profiled and placed in the pantheon of those who have demonstrated extraordinary creativity. Observations and speculations about the specialization and elaboration of brain structures in musicians evolve into a discussion of artificial intelligence as a foil to what constitutes the essence of humanity. Taking an inductive approach, the author juxtaposes the conclusion about "music, musicians, and the brain" with the theme of the 2004 annual meeting of the AANS, "Advancing Patient Care Through Technology and Creativity," to elaborate on the characteristics of the consummate neurosurgeon. (Note: Musical vignettes used in the address can be found in the accompanying article posted on Neurosurgical Focus http://www.aans.org/education/journal/neurosurgical).

    S-Genius is a new universal scatterometry platform, which gathers all the LTM-CNRS know-how regarding the rigorous electromagnetic computation and several inverse problem solver solutions. This software platform is built to be a userfriendly, light, swift, accurate, user-oriented scatterometry tool, compatible with any ellipsometric measurements to fit and any types of pattern. It aims to combine a set of inverse problem solver capabilities — via adapted Levenberg- Marquard optimization, Kriging, Neural Network solutions — that greatly improve the reliability and the velocity of the solution determination. Furthermore, as the model solution is mainly vulnerable to materials optical properties, S-Genius may be coupled with an innovative material refractive indices determination. This paper will a little bit more focuses on the modified Levenberg-Marquardt optimization, one of the indirect method solver built up in parallel with the total SGenius software coding by yours truly. This modified Levenberg-Marquardt optimization corresponds to a Newton algorithm with an adapted damping parameter regarding the definition domains of the optimized parameters. Currently, S-Genius is technically ready for scientific collaboration, python-powered, multi-platform (windows/linux/macOS), multi-core, ready for 2D- (infinite features along the direction perpendicular to the incident plane), conical, and 3D-features computation, compatible with all kinds of input data from any possible ellipsometers (angle or wavelength resolved) or reflectometers, and widely used in our laboratory for resist trimming studies, etching features characterization (such as complex stack) or nano-imprint lithography measurements for instance. The work about kriging solver, neural network solver and material refractive indices determination is done (or about to) by other LTM members and about to be integrated on S-Genius platform.

    Communications between civilizations within our galaxy at the present level of radio engineering is possible, although civilizations must begin to search for each other to achieve this. If an extra-terrestrial civilization possessing a technology at our level wishes to make itself known and will transmit special radio signals to do this, then it can be picked up by us at a distance of several hundreds of light years using already existing radio telescopes and specially built radio receivers. If it wishes, this civilization can also send us information without awaiting our answer.

  15. Of Genius and Epiphany: Schlafes Bruder, Das Parfum, and Babette's Feast

    Directory of Open Access Journals (Sweden)

    Nicholas Vazsonyi

    1999-06-01

    Full Text Available At first sight, all three works under consideration— Schlafes Bruder (1992, Das Parfum (1985, and Babette's Feast (1950—appear to conform to "postmodern" conventions, such as a rejection of logocentrism or a playful borrowing of pre-existing literary motifs and styles. However, all three works also revive the category of "natural genius," despite the twentieth-century rejection of romantic idealism in matters of aesthetics. Moreover, these "geniuses" create "masterpieces," which invariably trigger epiphanous moments for the untrained and unsuspecting audiences to whom they are presented. This is true even for the otherwise parody- and pastiche-filled Perfume , where the phenomenon of genius and the irresistible effect of a "masterpiece" is treated seriously nonetheless. The article compares these three texts, revealing surprising correspondences in ideas, themes, and often even in the choice of words. It further ponders whether these authors have abandoned the post-Nietzschean relativization of "beauty" and "truth" by returning unreflectedly to a sentimental romanticism, or whether they suggest the transcendence of postmodernism.

  17. Knowing more than they can tell: An assessment of genre awareness among students in writing intensive zoology and civil engineering courses

    Science.gov (United States)

    Hanson, Joleen Kidwell

    Developing genre awareness as a means of "learning how to learn" in new writing situations is a goal of four recently proposed writing pedagogies that recognize the context-dependent nature of standards for "good writing" (Devitt, Reiff, and Bawarshi (2004); Beaufort (2007); Johns (2008); Downs and Wardle (2007)). Yet other scholars argue that useful genre knowledge cannot be taught explicitly in the classroom, but must be acquired tacitly through participation in a workplace or other discourse community (Dias et al. (1999); Freedman (1994); Smit (2004)). This qualitative study investigates the range of variability and potential sources of genre awareness among undergraduates who had not received explicit teaching about genre awareness. It presents students' explicit understanding of why particular genre conventions are followed in a particular context by examining what they could tell about learning the advanced lab report in writing-in-the-major courses in either Zoology or Civil Engineering. Research data includes surveys of all students in three courses (n=112), interviews with a subset in each course (n=24) and with all instructors (n=7), samples of graded student lab reports, and classroom observations. Overall, few study participants demonstrated genre awareness as defined by Devitt. Students showed limited awareness of the rhetorical purposes of the advanced lab report and even less awareness of the values and beliefs embedded in its discourse conventions. Disciplinary identification and mentoring experiences were found to be factors that might contribute to the development of genre awareness. Unexpected findings were that some insecure writers showed relatively high overall genre awareness, while some confident writers showed relatively low genre awareness. Further research is needed to refine an assessment instrument that could be readily used by other researchers. However, the instrument for assessing genre awareness that was developed for this project

    Swedish producers, authorities and users have acknowledged the need for common environmental guidelines for residues. The objective of this project has been to develop a proposal for common environmental guidelines for reuse of ash in civil engineering applications. The project has a narrow risk assessment with application on an strictly nearfield, local perspective and focus on a limited set of substances. Health aspects for construction workers are not covered in the project. The starting point in the risk assessment is the assumption that ashes may be used just like any conventional construction material. Special requirements or regulations regarding precautionary actions in the handling of ashes, regarding the site or surroundings will be avoided. The guiding principle has been the precautionary principle: reuse of ash is acceptable only if it constitute an insignificant risk to health and environment. The calculations are based on defined emission- and exposure scenarios. The concept of insignificant risk imply that the impact in the defined points of compliance does not exceed established health- and environmental criteria. The model address health risks associated with spreading of particles and exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries and consumption of ground water. Off-site environmental effects in surface waters and in soil as well as health- and environmental risks in the post use phase are also considered. Exposure by dust is addressed in the same way as in the Swedish Environmental Protection Agency's guidelines for contaminated soil [12]. The guidelines values for exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berrys are total content, whereas the guidelines for exposure by consumption of ground water or environmental effects in surface waters are based on leaching properties of the ash. The guidelines rely on a conceptual model, defined emissions and

    Team Sports has been suggested as a suitable environment to investigate creative behavior. This study’s purpose was two-fold: first, it intended to identify the effects of the Skills4Genius sports-bases training program in thinking, motor, and in-game creative behavior in team sports. Second, it aimed to investigate the relationship between creative thinking and in-game creativity. Forty children from primary school were allocated into control (n = 18, age: 9.2±0.4) and experimental (n = 22, age: 9.5±0.7) groups. The experimental group participated in a five-month training program involving either creative thinking, diversification, physical literacy, and nonlinear pedagogy approaches (Skills4Genius). Variables in the study included: a) creative thinking; b) motor performance (vertical jump, speed, and agility); c) in-game individual creative behavior (attempts, fluency, and versatility); and d) in-game collective behavior (positional regularity). The results suggested that the Skills4Genius program fostered creative thinking, agility, and speed performance. Moreover, it stretched the in-game individual creative behavior mainly through the improvement of the attempts and versatility of the player’s actions. Lastly, it nurtured a better learning of the tactical principles, whereas the children were more coordinated with their teammates’ and opponents’ positioning. Additionally, this study presents a positive correlation linking creative thinking and in-game creative performance. These findings highlighted that creativity is facilitated while players become more thinking and game-skilled. Coaches and educators may apply this functional environment to inspire children’s disposition to move outside the box and trigger a creative spark in team sports players. Notwithstanding, the sports environment is ideally suited for fostering creative behavior, a higher-order disposition that will go on to differentiate the everyday life of a child. PMID:28231260

  10. From Narcissus to Genius through the Work of Pleshette DeArmitt

    Directory of Open Access Journals (Sweden)

    Marygrace Hemme

    2015-12-01

    Full Text Available Through my reading of the section of Pleshette Dearmitt’s book The Right to Narcissism, entitled “Kristeva: the Rebirth of Narcissus,” I illustrate the way in which DeArmitt’s reading of Narcissus is reflected in Julia Kristeva’s conception of genius. DeArmitt describes narcissism as a structure through which subjectivity, language, self-love, and love for the other come about. Narcissism develops through a metaphorical relation of identification with a “loving third” in which the subject-in-formation is transferred to the site of the other, to the place from which he or she is seen and heard through the words of the mother directed at an other. The emerging subject catches the words of others and repeats them. The speech of the other, then, is a model or pattern with which the subject-in-formation identifies repeatedly, and it is through identifying with the third that the forming subject becomes like the other, a speaking subject herself. All love comes from narcissism because it is a repetition of this identification and transference. I connect this account to Kristeva’s Female Genius Trilogy by claiming that these works are love stories since they are based on a repetition of the narcissistic structure on a cultural level in their content and in their form, though for each genius it manifests through a different register. For Hannah Arendt the relation is between the actor and the spectator; for Melanie Klein it is between the analyst and the analysand; and for Colette it is between the writer and the reader.

  15. CloudGenius: Decision Support for Web Server Cloud Migration

    CERN Document Server

    Menzel, Michael

    2012-01-01

    Cloud computing is the latest computing paradigm that delivers hardware and software resources as virtualized services in which users are free from the burden of worrying about the low-level system administration details. Migrating Web applications to Cloud services and integrating Cloud services into existing computing infrastructures is non-trivial. It leads to new challenges that often require innovation of paradigms and practices at all levels: technical, cultural, legal, regulatory, and social. The key problem in mapping Web applications to virtualized Cloud services is selecting the best and compatible mix of software images (e.g., Web server image) and infrastructure services to ensure that Quality of Service (QoS) targets of an application are achieved. The fact that, when selecting Cloud services, engineers must consider heterogeneous sets of criteria and complex dependencies between infrastructure services and software images, which are impossible to resolve manually, is a critical issue.

    Swedish producers, authorities and users have acknowledged the need for common environmental guidelines for residues. The objective of this project has been to develop a proposal for common environmental guidelines for reuse of ash in civil engineering applications. The project has a narrow risk assessment with application on an strictly nearfield, local perspective and focus on a limited set of substances. Health aspects for construction workers are not covered in the project. The starting point in the risk assessment is the assumption that ashes may be used just like any conventional construction material. Special requirements or regulations regarding precautionary actions in the handling of ashes, regarding the site or surroundings will be avoided. The guiding principle has been the precautionary principle: reuse of ash is acceptable only if it constitute an insignificant risk to health and environment. The calculations are based on defined emission- and exposure scenarios. The concept of insignificant risk imply that the impact in the defined points of compliance does not exceed established health- and environmental criteria. The model address health risks associated with spreading of particles and exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berries and consumption of ground water. Off-site environmental effects in surface waters and in soil as well as health- and environmental risks in the post use phase are also considered. Exposure by dust is addressed in the same way as in the Swedish Environmental Protection Agency's guidelines for contaminated soil [12]. The guidelines values for exposure by dust, oral intake, dermal contact and intake by vegetables or wild grown berrys are total content, whereas the guidelines for exposure by consumption of ground water or environmental effects in surface waters are based on leaching properties of the ash. The guidelines rely on a conceptual model, defined emissions and

    Schwartz, Stephan A

    2010-01-01

    Two hundred years of reductive materialism has failed to explain the extraordinary experiences we know as moments of genius, religious epiphany, and psychic insight. This paper proposes that these three experiences are in essence the same experience, differentiated only by intention and context. It reaches this conclusion based on well-conducted experimental research across the continuum of science--work that proposes a new interdependent model of consciousness that takes into consideration a nonlocal linkage or entanglement, as an aspect of consciousness not limited by space and time. The paper surveys some of the most important relevant research from quantum biology, physics, psychology, medicine, anthropology, and parapsychology. It proposes that more attention should be paid to the autobiographies, correspondence, and journals of men and women to whom history unequivocally accords the designation of genius, saint, or psychic, offering examples from these sources. And it presents comparisons between ethnohistorical material and spiritual traditions, suggesting they arrive at a similar worldview. Finally, it proposes that meditation research, some examples of which are cited, be seen in the context of psychophysical self-regulation, and that it offers one powerful avenue for producing these exceptional experiences.

    Full Text Available The history, present and future of the compression ignition engine is a fascinating story that spans over 100 years, from the time of Rudolf Diesel to the highly regulated and computerized engines of the 21st Century. The development of these engines provided inexpensive, reliable and high power density machines to allow transportation, construction and farming to be more productive with less human effort than in any previous period of human history. The concept that fuels could be consumed efficiently and effectively with only the ignition of pressurized and heated air was a significant departure from the previous coal-burning architecture of the 1800s. Today, the compression ignition engine is undergoing yet another revolution. The equipment that provides transport, builds roads and infrastructure, and harvests the food we eat needs to meet more stringent requirements than ever before. How successfully 21st Century engineers are able to make compression ignition engine technology meet these demands will be of major influence in assisting developing nations (with over 50% of the world’s population achieve the economic and environmental goals they seek.

    A nitrogen decision support system in the form of a game (NitroGenius) was developed for the Second International Nitrogen Conference. The aims were to: i) improve understanding among scientists and policy makers about the complexity of nitrogen pollution problems in an area of intensive agricultural, industrial, and transportation activity (The Netherlands); and ii) search for optimal policy solutions to prevent pollution effects at lowest economic and social costs. NitroGenius includes a model of nitrogen flows at relevant spatial and temporal scales including emissions of ammonia and nitrogen oxides and contamination of surface- and groundwaters. NitroGenius also includes an economic model describing relationships for important sectors and impacts of different nitrogen control measures on Gross Domestic Product (GDP), unemployment, energy use, and environmental costs. About 50 teams played NitroGenius during the Second International Nitrogen Conference. The results show that careful planning and selection of abatement options can solve Dutch nitrogen problems at reasonable cost.

  13. Gendering Prayer: Millennial-generation Catholics and the Embodiment of Feminine Genius and Authentic Masculinity

    Directory of Open Access Journals (Sweden)

    Katherine Anne Dugan

    2017-06-01

    Full Text Available This article examines the relationship between prayer practices and gendered subjectivity among a group of millennial-generation Catholic men and women. Drawing on ethnographic work, this case study illuminates the role of prayer in shaping how, why, and with what sorts of struggles young and culturally-savvy women and men embodied gender complementarity in the twenty-first century U.S. This article proposes gendering prayer as an analytic for understanding how prayer cultivated these Catholics in the habits of feminine genius and authentic masculinity. By comparing women’s and men’s practices, I argue that these young adults were flourishing in the modern world, even as they rejected egalitarian gender roles in favor of multiple modes of submission within gender essentialism. This work contributes to anthropological scholarship focused on gender performance in daily Catholic life.

    Ludwig van Beethoven is nowadays considered to be one of the greatest composers in the history of music and his myth-like reputation is enhanced by his deafness; however, deafness was not the only condition which affected his genius. Due to the many lamentations contained in his letters about continuously recurring health problems, various attempts at an interpretation of Beethoven's personality have been undertaken. These included psychoanalytical considerations with respect to his father-mother relationship and also diagnostic attempts with reference to the symptoms of a possible borderline personality syndrome. The aim of this article is to comprehensively analyze the diseases of the patient Beethoven from the perspective of specialized medical disciplines based on new research results, to summarize various discipline-specific considerations and to make a contemporary assessment from the viewpoint of current scientific results.

    Daniel Storage

    Full Text Available Women and African Americans-groups targeted by negative stereotypes about their intellectual abilities-may be underrepresented in careers that prize brilliance and genius. A recent nationwide survey of academics provided initial support for this possibility. Fields whose practitioners believed that natural talent is crucial for success had fewer female and African American PhDs. The present study seeks to replicate this initial finding with a different, and arguably more naturalistic, measure of the extent to which brilliance and genius are prized within a field. Specifically, we measured field-by-field variability in the emphasis on these intellectual qualities by tallying-with the use of a recently released online tool-the frequency of the words "brilliant" and "genius" in over 14 million reviews on RateMyProfessors.com, a popular website where students can write anonymous evaluations of their instructors. This simple word count predicted both women's and African Americans' representation across the academic spectrum. That is, we found that fields in which the words "brilliant" and "genius" were used more frequently on RateMyProfessors.com also had fewer female and African American PhDs. Looking at an earlier stage in students' educational careers, we found that brilliance-focused fields also had fewer women and African Americans obtaining bachelor's degrees. These relationships held even when accounting for field-specific averages on standardized mathematics assessments, as well as several competing hypotheses concerning group differences in representation. The fact that this naturalistic measure of a field's focus on brilliance predicted the magnitude of its gender and race gaps speaks to the tight link between ability beliefs and diversity.

    The persistent mad-genius controversy concerns whether creativity and psychopathology are positively or negatively correlated. Remarkably, the answer can be "both"! The debate has unfortunately overlooked the fact that the creativity-psychopathology correlation can be expressed as two independent propositions: (a) Among all creative individuals, the most creative are at higher risk for mental illness than are the less creative and (b) among all people, creative individuals exhibit better mental health than do noncreative individuals. In both propositions, creativity is defined by the production of one or more creative products that contribute to an established domain of achievement. Yet when the typical cross-sectional distribution of creative productivity is taken into account, these two statements can both be true. This potential compatibility is here christened the mad-genius paradox. This paradox can follow logically from the assumption that the distribution of creative productivity is approximated by an inverse power function called Lotka's law. Even if psychopathology is specified to correlate positively with creative productivity, creators as a whole can still display appreciably less psychopathology than do people in the general population because the creative geniuses who are most at risk represent an extremely tiny proportion of those contributing to the domain. The hypothesized paradox has important scientific ramifications.

    styles, which raises the question of how to assess the individual student’s learning where widely different strategies with widely differing results are employed. While offering many interesting possibilities, the integration of these historically separated disciplines embraces paradoxes......, and uses PBL and project-oriented models for its educational form. There is a distinct difference between engineering and architecture in their evolutionary backgrounds and their varying degree of emphasis on natural science. Both present different forms of problem solving that appeal to different learning...... and contradictions reflected in the differences inherent in two pedagogical models used by the university, problem-based learning and project-oriented learning. However, in order for this to be adequately demonstrated, suitable forms of evaluation are necessary. A case is made for the review of assessment criteria...

  13. From ``wiggly structures'' to ``unshaky towers'': problem framing, solution finding, and negotiation of courses of actions during a civil engineering unit for elementary students

    Roth, Wolff-Michael

    1995-12-01

    The present study was designed to investigate problem- and solution-related activity of elementary students in ill-defined and open-ended settings. One Grade 4/5 class of 28 students engaged in the activities of the “Engineering for Children: Structures” curriculum, designed as a vehicle for introducing science concepts, providing ill-defined problem solving contexts, and fostering positive attitudes towards science and technology. Data included video recordings, ethnographic field notes, student produced artefacts (projects and engineering logbooks), and interviews with teachers and observers. These data supported the notion of problems, solutions, and courses of actions as entities with flexible ontologies. In the course of their negotiations, students demonstrated an uncanny competence to frame and reframe problems and solutions and to decide courses of actions of different complexities in spite of the ambiguous nature of (arte)facts, plans, and language. A case study approach was chosen as the literary device to report these general findings. The discussion focuses on the inevitably ambiguous nature of (arte)facts, plans, and language and the associated notion of “interpretive flexibility.” Suggestions are provided for teachers on how to deal with interpretive flexibility without seeking recourse to the didactic approaches of direct teaching. But what happens when problems and solutions are negotiable, when there are no longer isolated problems which one tries to solve but problems which maintain complex linkages with ensembles of other problems and diverse constraints, or when problems and solutions are simultaneously invented?

    Full Text Available The European Union increases the judiciary cooperation in civil and comercial cases with trans-border incidence, based on the principle of mutual recognition of judiciary rulings. The aim of adopting frame-legislation is to ensure the developement of civil procedures. The Council Regulations no. 44/2001 on the competence, the recognition and the enforcement of judiciary rulings in civil and commercial cases is a “real” Code of civil procedure in this matter, to be applied in the member states, thus ensuring the free circulation of the judiciary rulings according to the principles of mutual recognition, mutual trust and reinforcement of juridical security in the union. The community civil procedural code prevails over the national procedural code. The Regulations ensure the administration of the community justice and through their rules avoid the pronunciation, in the member states, of rulings that are irreconcilable with each other, the direct beneficiaries being legal and natural persons.
