    The mining and energy industries present unique challenges to engineers, who must navigate sometimes competing responsibilities and codes of conduct, such as personal senses of right and wrong, professional ethics codes, and their employers' corporate social responsibility (CSR) policies. Corporate social responsibility (CSR) is the current dominant framework used by industry to conceptualize firms' responsibilities to their stakeholders, yet has it plays a relatively minor role in engineering ethics education. In this article, we report on an interdisciplinary pedagogical intervention in a petroleum engineering seminar that sought to better prepare engineering undergraduate students to critically appraise the strengths and limitations of CSR as an approach to reconciling the interests of industry and communities. We find that as a result of the curricular interventions, engineering students were able to expand their knowledge of the social, rather than simply environmental and economic dimensions of CSR. They remained hesitant, however, in identifying the links between those social aspects of CSR and their actual engineering work. The study suggests that CSR may be a fruitful arena from which to illustrate the profoundly sociotechnical dimensions of the engineering challenges relevant to students' future careers.

    Geostatistics is a common tool in reservoir characterisation. Several texts discuss the subject, however this book differs in its approach and audience from currently available material. Written from the basics of statistics it covers only those topics that are needed for the two goals of the text: to exhibit the diagnostic potential of statistics and to introduce the important features of statistical modeling. This revised edition contains expanded discussions of some materials, in particular conditional probabilities, Bayes Theorem, correlation, and Kriging. The coverage of estimation, variability, and modeling applications have been updated. Seventy examples illustrate concepts and show the role of geology for providing important information for data analysis and model building. Four reservoir case studies conclude the presentation, illustrating the application and importance of the earlier material. This book can help petroleum professionals develop more accurate models, leading to lower sampling costs.

    Full Text Available The upstream of the petroleum industry involves itself in the business of oil and gas exploration and production (E & P activities. While the exploration activities find oil and gas reserves, the production activities deliver oil and gas to the downstream of the industry. The petroleum production is definitely the heart of the petroleum industry. Petroleum production engineering is that part of petroleum engineering that attempts to maximize oil and gas production in a cost-effective manner. To achieve this objective, production engineers need to have a thorough understanding of the petroleum production systems with which they work. The purpose of this paper is to identify the most important advances in petroleum production engineering in the past decade. Of course, a review paper in the allotted space simply cannot do justice to all new technologies, especially those that are advances to established techniques. We then expound upon two technologies that we feel have made already or have the capacity of quantum impact on the petroleum industry. These are high-permeability fracturing (often referred to in the vernacular as frac-pack and variants and complex well architecture which deals with wells with a main or mother bore from which branches are drilled.

    Full Text Available This present research aims at identifying register used in the conversations among petroleum engineers by examining the linguistic feature which is viewed from the aspect of the field, the tenor and the mode of discourse of the Systemic Functional Linguistics (SFL approach. Findings show that in the field of discourse, all terms of register found in the experiential domain analysis function as technical terms, of which the two major forms of nouns and verbs (i.e., single-word and compound/phrasal word forms are the most frequent categories identified among other kinds of technical terms. The goal orientation appears to have both short and long term while the social activity results in exchanges among participants. In the tenor of discourse, the agentive role is said to be equal and the social role is considered as non-hierarchic. The social distance within the interaction is said to be minimal which is excessively characterized by the use of informal form of expressions. In the mode of discourse, the language role exists equally of both constitutive and ancillary identified by the use of present simple tense and non-present tenses, that is, future simple, past simple and present perfect. The channel is in phonic form. The medium is in spoken with visual contact as it is largely characterized by the use of endophoric reference as well as pronouns.

  11. Engineering geology studies in the National Petroleum Reserve, Alaska

    Kachadoorian, Reuben; Crory, F.E.

    1984-01-01

    Engineering geology studies were conducted in direct support of the exploration program in the National Petroleum Reserve, Alaska. The studies included laboratory and field tests and observations to address design and construction problems of airfields, roads, drill pads and foundations, and to evaluate their actual performance. Permafrost containing large amounts of near surface ground ice as wedges, masses, and intergranular ice, required that all construction activity not disturb the thermal regime of the ground surface, which could lead to thaw of permafrost and ground subsidence. Summer activity, therefore was not allowable, yet the winter climate was so harsh that winter work was slow and inefficient. To allow summer operations at well sites planned for all year activity, it was necessary to adapt existing techniques for arctic construction and to devise new ones. The design and construction of facilities at the deep exploration wells at Inigok, Tunalik, and Lisburne posed the greatest challenge. These sites, requiring a year or more to drill, could only be attempted if continuous access to drilling and logistic supplies could be assured throughout the year, including the possibility of bringing in another drill rig, in the event of a blowout. Thus all-seasons airstrips were required at these wells. Sufficient quantities of local gravel were not readily available at the Inigok and Tunalik sites to construct the airstrips with the required 6 feet or more of gravel to prevent the underlying permafrost from thawing. Therefore, insulation was used to maintain the subbase of local sands in a continuously frozen state, which in turn was overlain by 15 inches of gravel or sandy gravel. Tests at the U.S. Army Waterways Experimental Station defined the minimum thickness of gravel required above the insulation to provide the desired bearing capacity for the C-130 type aircraft without crushing the insulation. Field testing also included the evaluation of another design

    By the year 2000, there will be far fewer international service companies, but they will be larger and more capable. The service company engineer will have to better understand the needs and problems of the international oil companies, as he will have to work in partnership with their personnel in mostly hostile environments. He will have to be broader and more of a systems thinker. He will have to be proficient in computer and software technology and an effective team player with good communication and interpersonal skills. The paper details the technical problems that the engineer will have to face and the qualifications that will be required of an entry level service company engineer at that time. The environment in the year 2000 in which the EandP service company engineer will have to function is addressed as background to the above forecasts. Projections are provided for the likely economic, political and business climates at that time.

    Hanging casing strings are used for oil and brine transfer in the domal salt storage caverns of the Strategic Petroleum Reserve (SPR). Damage to these casings is of concern because hanging string replacement is costly and because of implications on cavern stability. Although the causes of casing damage are not always well defined, many events leading to damage are assumed to be the result of salt falls impacting the hanging strings. However, in some cases, operational aspects may be suspected. The history of damage to hanging strings is updated in this study to include the most recent events. Potential general domal and local operational and material factors that could influence the tendency for caverns to have salt falls are examined in detail. As a result of this examination, general factors, such as salt dome anomalies and crude type, and most of the operational factors, such as geometry, location and depressurizations, are not believed to be primary causes of casing damage. Further analysis is presented of the accumulation of insolubles during cavern solutioning and accumulation of salt fall material on the cavern floor. Inaccuracies in sump geometry probably make relative cavern insolubles contents uncertain. However, determination of the salt fall accumulations, which are more accurate, suggest that the caverns with the largest salt fall accumulations show the greatest number of hanging string events. There is good correlation between the accumulation rate and the number of events when the event numbers are corrected to an equivalent number for a single hanging string in a quiescent, operating cavern. The principal factor that determines the propensity for a cavern to exhibit this behavior is thought to be the effect of impurity content on the fracture behavior of salt.

  16. Estimating decades-long trends in petroleum field energy return on investment (EROI) with an engineering-based model.

    2017-01-01

    This paper estimates changes in the energy return on investment (EROI) for five large petroleum fields over time using the Oil Production Greenhouse Gas Emissions Estimator (OPGEE). The modeled fields include Cantarell (Mexico), Forties (U.K.), Midway-Sunset (U.S.), Prudhoe Bay (U.S.), and Wilmington (U.S.). Data on field properties and production/processing parameters were obtained from a combination of government and technical literature sources. Key areas of uncertainty include details of the oil and gas surface processing schemes. We aim to explore how long-term trends in depletion at major petroleum fields change the effective energetic productivity of petroleum extraction. Four EROI ratios are estimated for each field as follows: The net energy ratio (NER) and external energy ratio (EER) are calculated, each using two measures of energy outputs, (1) oil-only and (2) all energy outputs. In all cases, engineering estimates of inputs are used rather than expenditure-based estimates (including off-site indirect energy use and embodied energy). All fields display significant declines in NER over the modeling period driven by a combination of (1) reduced petroleum production and (2) increased energy expenditures on recovery methods such as the injection of water, steam, or gas. The fields studied had NER reductions ranging from 46% to 88% over the modeling periods (accounting for all energy outputs). The reasons for declines in EROI differ by field. Midway-Sunset experienced a 5-fold increase in steam injected per barrel of oil produced. In contrast, Prudhoe Bay has experienced nearly a 30-fold increase in amount of gas processed and reinjected per unit of oil produced. In contrast, EER estimates are subject to greater variability and uncertainty due to the relatively small magnitude of external energy investments in most cases.

    In this study, the combustion characteristics and emissions of two different petroleum diesel fuels (No. 1 and No. 2) and biodiesel from soybean oil were compared. The tests were performed at steady state conditions in a four-cylinder turbocharged DI diesel engine at full load at 1400-rpm engine speed. The experimental results compared with No. 2 diesel fuel showed that biodiesel provided significant reductions in PM, CO, and unburned HC, the NO(x) increased by 11.2%. Biodiesel had a 13.8% increase in brake-specific fuel consumption due to its lower heating value. However, using No. 1 diesel fuel gave better emission results, NO(x) and brake-specific fuel consumption reduced by 16.1% and 1.2%, respectively. The values of the principal combustion characteristics of the biodiesel were obtained between two petroleum diesel fuels. The results indicated that biodiesel may be blended with No. 1 diesel fuel to be used without any modification on the engine.

    Experiments are conducted on engine performance and sprays and a characteristics analysis is made between diesel and mixed liquefied petroleum gas (LPG)/diesel injection engines. The performance test results show that with LPG the mixed ratio increases, engine power reduces slightly, fuel consumption and engine noise have almost no change, pollutant emissions of smoke, CO and NO{sub x} at full load are improved significantly, but the amount of unburned HC increases. The experimental results of the sprays indicate that because of flash boiling injection of mixed fuel, mean diameters in a spray decrease, the number distribution curve of fuel droplet size moves towards smaller diameters, small-size droplet numbers increase, spray quality is good and engine smoke reduces accordingly. Because large-size droplet diameters show almost no change and small-size droplet diameters decrease, the relative span factor and dispersion boundary factor of the droplet diameter increase. High-resolution digital camera photography is invaluable when carrying out a comparative investigation of spray. (author)

  20. A Typical Case Study: Solid Waste Management in Petroleum Refineries

    2008-01-01

    Full Text Available The current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel production and land filling. Waste management models have a common approach of assignment of generating sources to landfills, transfer stations sitting, site selection for landfills, etc. but recently new integrated models have been developed and applied. Waste management system in an industrial complexes uses multi-objective mixed integer programming approach for the running of existing facilities in dynamic net work flow models with nonlinear costs of management. The latest multi-objective mixed integer programming techniques are applied to resolve the potential conflict between environmental and economic goals and to evaluate sustainable strategies for waste management. In this approach, material recycling in an economic sense exhibits huge indirect benefits, although the emphasis of environmental quality as a major objective in decision-making drives the optimal solution toward pro-recycling programs. The use of grey and fuzzy system theories as uncertainty analysis tools as an enhancement of this modeling analysis proves to be highly profitable. A multi-objective optimization model based on the goal programming approach has been developed and tested in this study for passable management of solid waste generated by a typical petroleum refining industry in the state of Kuwait. The analytic hierarchy process, a decision-making approach, including qualitative and quantitative aspects of a problem, has been integrated in the model to prioritize the conflicting goals existing in the waste management problems of the petroleum

    Full Text Available Increased environmental awareness and depletion of resources are driving the industries to develop viable alternative fuels like vegetable oils, compresed natural gas, liquid petroleum gas, producer gas, and biogas in order to provide suitable substitute to diesel for compression ignition engine. In this investigation, a single cylinder, vertical, air-cooled diesel engine was modified to use liquid petroleum gas in dual fuel mode. The liquefied petroleum gas, was mixed with air and supplied through intake manifold. The liquid fuel neem oil or diesel was injected into the combustion chamber. The performance, emission, and combustion characteristics were studied and compared for neat fuel and dual fuel mode. The experimental results on dual fuel engine show a reduction in oxides of nitrogen up to 70% of the rated power and smoke in the entire power range. However the brake thermal efficiency was found decreased in low power range due to lower calorific value of liquid petroleum gas, and increase in higher power range due to the complete burning of liquid petroleum gas. Hydrocarbon and carbon monoxide emissions were increased significantly at lower power range and marginal variation in higher power range.

    Contamination of soil by petroleum products is a current problem in several countries in the world. In Algeria, this negative phenomenon is highly remarked in Saharan region. Numerous studies at the University of Ouargla that we will review in this paper, have tried to find an effective solution to eliminate the hydrocarbons from the soil by the technique of "biodegradation" which is a natural process based on microorganisms such as Bacillus megaterium and Pseudomonas aeruginosa. Presence of aboriginal strain Bacillus megaterium in the soil samples with different ages of contamination has shown a strong degradation of pollutants. This strain chosen for its short time of generation which is performing as seen the best yields of elimination of hydrocarbons assessed at 98 % biostimule by biosurfactant, also 98% on a sample wich bioaugmente by urea, and 86 % of the sample which biostimule by nutrient solution. The rate of biodegradation of the contaminated soil by crude oil using the strain Pseudomonas aeruginosa is higher in the presence of biosurfactant 53 % that in his absence 35 %. Another elimination technique wich is washing the contaminated soil's sample by centrifugation in the presence of biosurfactant where The rate of hydrocarbons mobilized after washing soil by centrifugation is of 50 % and 76 % but without centrifugation it was of 46% to 79%. Those processes have great capacity in the remobilization of hydrocarbons and acceleration of their biodegradation; thus, they deserve to be further developed in order to prevent environmental degradation in the region of Ouargla.

    Recycling waste materials produced in our daily life is considered as an additional resource of a wide range of materials and it conserves the environment. Used engine oil and used cooking oil are two oils disposed off in large quantities as a by-product of our daily life. This study aims at providing white bio oil, bio petroleum diesel and heavy fuel from the disposed oils. Toxic organic materials suspected to be present in the used engine oil were separated using vacuum column chromatography to reduce the time needed for the separation process and to avoid solvent usage. The compounds separated were detected by gas chromatography-mass spectrometry (GC-MS) and found to contain toxic aromatic carboxylic acids. Used cooking oils (thermally cracked from usage) were collected and separated by vacuum column chromatography. White bio oil produced was examined by GC-MS. The white bio oil consists of non-toxic hydrocarbons and is found to be a good alternative to white mineral oil which is significantly used in food industry, cosmetics and drugs with the risk of containing polycyclic aromatic compounds which are carcinogenic and toxic. Different portions of the used cooking oil and used engine were mixed to produce several blends for use as heavy oil fuels. White bio oil was used to produce bio petroleum diesel by blending it with petroleum diesel and kerosene. The bio petroleum diesel produced passed the PETRONAS flash point and viscosity specification test. The heat of combustion of the two blends of heavy fuel produced was measured and one of the blends was burned to demonstrate its burning ability. Higher heat of combustion was obtained from the blend containing greater proportion of used engine oil. This study has provided a successful recycled alternative for white bio oil, bio petroleum fuel and diesel which can be an energy source.

  6. Innovation and performance: The case of the upstream petroleum sector

    Science.gov (United States)

    Persaud, A. C. Jai

    This thesis investigates innovation in the upstream crude oil and natural gas sector, a strategic part of the Canadian economy and a vital industry for North American energy trade and security. Significant interest exists in understanding innovation in this sector from a private and public policy perspective. Interest in the sector has intensified recently due to concerns about world oil supply, Canada's oil sands development, and the potential that Canada may become an "energy superpower." The study examines the factors that drive companies involved in exploration, development, and production in the upstream petroleum sector to innovate and the impact of their innovation activities through major technologies on their performance. The thesis focuses on process innovation, which involves the adoption of new or significantly improved production processes, and is distinct from product innovation, which is based on the development and commercialization of a product with improved product characteristics to deliver new services to the consumer. The thesis provides a comprehensive review of the literature and develops an investigative model framework to examine the drivers of innovation and the impact of innovation on performance in the upstream petroleum sector. The research employs a survey questionnaire that was developed to obtain data and information, which was missing in the literature or not publicly available to test key relationships of innovation and performance indicators. In addition to the survey questionnaire, a number of knowledgeable experts in the industry were also interviewed.

    The geology and reservoir-engineering data were integrated in the 2002 U.S. Geological Survey assessment of the National Petroleum Reserve in Alaska (NPRA). VVhereas geology defined the analog pools and fields and provided the basic information on sizes and numbers of hypothesized petroleum accumulations, reservoir engineering helped develop necessary equations and correlations, which allowed the determination of reservoir parameters for better quantification of in-place petroleum volumes and recoverable reserves. Seismic- and sequence-stratigraphic study of the NPRA resulted in identification of 24 plays. Depth ranges in these 24 plays, however, were typically greater than depth ranges of analog plays for which there were available data, necessitating the need for establishing correlations. The basic parameters required were pressure, temperature, oil and gas formation volume factors, liquid/gas ratios for the associated and nonassociated gas, and recovery factors. Finally, the re sults of U.S. Geological Survey deposit simulation were used in carrying out an economic evaluation, which has been separately published. Copyright ?? 2005.

    Full Text Available The present work involves the synthesis of a petroleum-based fuel by the catalytic pyrolysis of waste plastics. Catalytic pyrolysis involves the degradation of the polymeric materials by heating them in the absence of oxygen and in the presence of a catalyst. In the present study different oil samples are produced using different catalysts under different reaction conditions from waste plastics. The synthesized oil samples are subjected to a parametric study based on the oil yield, selectivity of the oil, fuel properties, and reaction temperature. Depending on the results from the above study, an optimization of the catalyst and reaction conditions was done. Gas chromatography-mass spectrometry of the selected optimized sample was done to find out its chemical composition. Finally, performance analysis of the selected oil sample was carried out on a compression ignition (CI engine. Polythene bags are selected as the source of waste plastics. The catalysts used for the study include silica, alumina, Y zeolite, barium carbonate, zeolite, and their combinations. The pyrolysis reaction was carried at polymer to catalyst ratio of 10 : 1. The reaction temperature ranges between 400°C and 550°C. The inert atmosphere for the pyrolysis was provided by using nitrogen as a carrier gas.

    Full Text Available Recently, the depletion of petroleum resources and the impact of exhaust emission caused by combustion towards environmental has been forced to all researchers to come out with an alternative ways to prevent this situation become worse. Liquefied petroleum gas (LPG is the most compatible and have a potential to become a source of energy for internal combustion engine. Unfortunately, the investigation of LPG in internal combustion engine among researcher still have a gap in research. Thus, in this study a 1-Dimensional simulation CAMPRO 1.6L engine model using GT-Power is developed to predict the performances of engines that using LPG as a fuel for internal combustion engine. The constructed model simulation will throughout the validation process with the experimental data to make sure the precision of this model. The validation process shows that the results have a good agreement between the simulation model and the experimental data. As a result, the performance of LPG simulation model shows that a Brake Torque (BT, Brake Power (BP and Brake Mean Effective Pressure (BMEP were significantly improved in average of 7% in comparison with gasoline model. In addition, Brake Specific Fuel Consumption (BSFC also shows an improvement by 5%, which is become more economic. Therefore, the developed GT-Power model offer a successful fuel conversion to LPG systems via retrofit technology to provide comprehensive support for implementation of energy efficient and environmental friendly vehicles.

    Economics at the Federal Trade Commission (FTC) covers both the antitrust and consumer protection missions. In this year's essay, we focus mainly on the competition-side of the agency. Drawing on a wealth of recent research, we provide descriptive and analytical information about the petroleum industry. Mergers, as always, were a major preoccupation of the FTC, and we discuss a few oil industry mergers as well as one leading litigated case - Arch Coal's acquisition of Triton Coal. Finally, we review the empirical literature on the effects of vertical restraints, noting that the literature supporting an animus toward such restraints is surprisingly weak.

  18. Interface modeling to predict well casing damage for big hill strategic petroleum reserve.

    Energy Technology Data Exchange (ETDEWEB)

    Ehgartner, Brian L.; Park, Byoung Yoon

    2012-02-01

    Oil leaks were found in well casings of Caverns 105 and 109 at the Big Hill Strategic Petroleum Reserve site. According to the field observations, two instances of casing damage occurred at the depth of the interface between the caprock and top of salt. This damage could be caused by interface movement induced by cavern volume closure due to salt creep. A three dimensional finite element model, which allows each cavern to be configured individually, was constructed to investigate shear and vertical displacements across each interface. The model contains interfaces between each lithology and a shear zone to examine the interface behavior in a realistic manner. This analysis results indicate that the casings of Caverns 105 and 109 failed by shear stress that exceeded shear strength due to the horizontal movement of the top of salt relative to the caprock, and tensile stress due to the downward movement of the top of salt from the caprock, respectively. The casings of Caverns 101, 110, 111 and 114, located at the far ends of the field, are predicted to be failed by shear stress in the near future. The casings of inmost Caverns 107 and 108 are predicted to be failed by tensile stress in the near future.

    Unintentional carbon monoxide poisonings and fatalities lead to many toxicity cases. Given the unusual physical properties of carbon monoxide-in that the gas is odorless and invisible-unorganized and erroneous methods in obtaining engineering evidence as required during the discovery process often occurs. Such evidence gathering spans domains that include building construction, appliance installation, industrial hygiene, mechanical engineering, combustion and physics. In this paper, we attempt to place a systematic framework that is relevant to key aspects in engineering evidence gathering for unintentional carbon monoxide poisoning cases. Such a framework aims to increase awareness of this process and relevant issues to help guide legal counsel and expert witnesses.

    2015-01-01

    Full Text Available In this study, we have investigated the recovery of energy lost as waste heat from exhaust gas and engine coolant, using an improved thermoelectric generator (TEG in a LPG fueled SI engine. For this purpose, we have designed and manufactured a 5-layer heat exchanger from aluminum sheet. Electrical energy generated by the TEG was then used to produce hydrogen in a PEM water electrolyzer. The experiment was conducted at a stoichiometric mixture ratio, 1/2 throttle position and six different engine speeds at 1800-4000 rpm. The results of this study show that the configuration of 5-layer counterflow produce a higher TEG output power than 5-layer parallel flow and 3-layer counterflow. The TEG produced a maximum power of 63.18 W when used in a 5-layer counter flow configuration. This resulted in an improved engine performance, reduced exhaust emission as well as an increased engine speed when LPG fueled SI engine is enriched with hydrogen produced by the PEM electrolyser supported by TEG. Also, the need to use an extra evaporator for the LPG fueled SI engine is eliminated as LPG heat exchangers are added to the fuel line. It can be concluded that an improved exhaust recovery system for automobiles can be developed by incorporating a PEM electrolyser, however at the expense of increasing costs.

    A case study was used to illustrate the challenge of evaluating clean technologies and making modifications to an alkylation unit at a refinery in the United Kingdom. The alkylation unit used hydrogen flouride as an alkylation catalyst and generated fluoridic wastes that required further treatment. The alkylation process is used to produce a high value petroleum blend used for transport fuels. Acidic catalysts are used to eliminate the need for high temperatures and pressures. The study identified possible alterations to enable partial recycling. Different system boundaries were identified. The study considered technological, social, environmental and economic changes associated with the implementation of the process. A life cycle inventory of various processes considered for the refinery was presented. Possible technological changes that could avoid, reduce, or enable partial recycling waste were presented. Losses to relief systems, defluorinators, potassium hydroxide (KOH) treaters, and neutralization systems were also considered. Results of the study showed that the decision-making process involved trade-offs between costs and benefits with considerable uncertainties. It was concluded that the financial scale of projects cannot be used as a guide to systematic sustainability assessment. 50 refs., 3 tabs., 6 figs.

    CONOCOPHILLIPS views Social Investment as an important element of contributing to social progress and achieving its view of Sustainable Growth. According to CONOCOPHILLIPS a company's ability to grow depends not only on its business successes but also on its reputation as a corporate citizen. This reputation is built largely by responsible civic actions, social investment and environmental stewardship. The company invests in programs that provide sustainable community development, benefit the stakeholders, are aligned with its strategic business objectives, and are consistent with its core values. CONOCOPHILLIPS recognizes that the most effective corporate social investment is achieved by pro actively identifying the key community needs and by entering into strategic partnerships with agencies and organizations that serve good causes. In Rio de Janeiro, Phillips Petroleum do Brasil, a subsidiary of CONOCOPHILLIPS, has been working with Projeto Uere, a non-profit non-governmental organization (NGO) that runs an educational program for children living under social risk in Favela da Mare. Projeto Uere performs preventive work, helping children overcome their learning and social difficulties. The Projeto Uere case study results will highlight the application of some of CONOCOPHILLIPS social investment policies and strategies used to select and evaluate partnership projects in Brazil.

    1997-01-01

    Geology and reservoir characteristics of Manitoba`s producing horizons were described, and recent activity in exploration and development prospects for the immediate future were reviewed. These prospects have improved considerably, thanks to recent efforts of the Manitoba Department of Energy and Mines to ensure that barriers to petroleum investment are eliminated. As a result of these and related efforts by the Manitoba government the investment climate is stable and competitive. Advantages in Manitoba include availability of Crown land at comparatively low prices, drilling and exploration incentives, low drilling and completion costs, and easy access to markets. Development drilling opportunities exist for each of Manitoba`s five producing formations (the sandstones of the Jurassic Melita and Amaranth formations, and the Mississippian Bakken Formation, and the carbonates of the Mississipian Lodgepole and Mission Canyon formations). Sample economic scenarios run on three development scenarios and modelled after typical Manitoba oil play were very favorable, indicating a potential rate of return on investments of 25 to 37 per cent and pay-out in 2.6 to 3.2 years. 10 refs., 7 tabs., 5 figs.

    Full Text Available Test results indicate that a fully loaded engine, fed with 10 vol % ethanol and petrol blends, has power output reduced by 1.67–3.2% at 1400 and 1800 rev/min, while the specific fuel consumption can be slightly increased (up to 4% at 1400 rev/min, and slightly decreased at 1800 rev/min. Carbon monoxide CO emissions of the fully loaded engine running on biofuel blend E10 are reduced by about 0–50% compared to those observed when petrol is used. To introduce ethanol and petrol blends with higher E20 concentration as an engine fuel, special adjustment of the fuel system is needed.Article in Lithuanian

    Full Text Available The article covers the use of geosynthetic casings in hydraulic engineering. The authors describe the structure of earth dams that have geosynthetic casings used as the reinforcement of downstream slopes. Results of stability calculations are provided. The authors consider several examples of effective application of advanced geosynthetic materials used in combination with local building materials as structural elements of hydraulic engineering facilities. Their analysis has demonstrated a strong potential and expediency of application of geosynthetic casings in the course of construction and renovation of low-pressure earth dams. The authors have also developed a new structure of an earth dam. The new earth dam has geosynthetic casings used as structural reinforcing elements of the crown and the downstream slope. The dam structure contemplates the overflow of high water. The structural strengths of the proposed solution include a smaller material consumption rate, lower labour intensiveness and cost of the slope reinforcement due to the application of local building materials used to fill the casings, fast and easy depositing of slope reinforcing elements, and high workability of its dismantling for repair purposes. The authors have also completed the analysis of stability of geosynthetic casings of downstream slopes of an earth dam. The analysis has proven high efficiency of a small slope ratio in combination with its anchorage and reinforcement of the downstream toe with the help of high-strength geogrids.

    Full Text Available In situ and ex situ bioremediation of oil contaminated effluent pits, sludge pits, oil spilled land and tank bottom, and effluent treatment plant (ETP oily sludge was carried out at Ankleshwar, Mehsana, Assam and Cauvery Asset of Oil and Natural Gas Corporation Limited (ONGC, India. The types of contaminant were heavy paraffinic, asphaltic and light crude oil and emulsified oily sludge /contaminated soil. An indigenous microbial consortium was developed by assembling four species of bacteria, isolated from various oil contaminated sites of India, which could biodegrade different fractions of total petroleum hydrocarbon (TPH of the oily waste to environment friendly end products. The said consortium was on a large scale field applied to the above oil installations and it successfully bioremediated 30,706 tonnes of different types of oily waste. In 65 case studies of different batch size of in situ and ex situ bioremediation processes, the initial TPH content varying from 69.20 to 662.70 g/kg of oily waste has been biodegraded to 5.30 – 16.90 g/kg of oily waste in a range of 2 to 33 months. Biodegradation rate varied in the range of 0.22 – 1.10 Kg TPH /day/m2 area due to the climatic condition of the treatment zone and the type of waste treated. The bioremediated soil was non-toxic and natural vegetation was found to be grown on the same ground. Successful eco-restoration of one large effluent pit of 26,000 m2 area was carried out by cultivation of local fish species after completion of bioremediation. Bioremediation technology has helped ONGC with the management of their hazardous oily wastes in an environment friendly manner. DOI: http://dx.doi.org/10.5755/j01.erem.68.2.5632

    2010-06-01

    Full Text Available Petroleum refining process produces a large amount of atmospheric pollutants including greenhouse gases which are attributed to global warming. The international community inevitably addressed the global warming issue by introducing a market-based mechanism known as Emission Trading Systems (ETS under the Kyoto Protocol which imposes binding limits to developed nations using three flexibility mechanisms, including the Clean Development Mechanism (CDM. This case study was carried out in a petroleum refinery in Malaysia to explore the possibility for the refinery to participate in CDM. Information was collected through observatory field survey at the refinery and documentation review. Results show that the current monitoring tool using indirect calculation of fuel consumption provides a comprehensive coverage of emission sources but the reporting frequency should be increased for data accuracy. An accounting system was then created to predict the emissions gap of the refinery with reference to the baseline-year set by the Kyoto Protocol. It was concluded that the refinery showed promising potential to participate in CDM to benefit from technology transfer by selling their ‘credits’ to Annex I countries despite the uncertainty on the impact of the carbon market in a Non-Annex I country.

    Petroleum coke or "petcoke" is a solid material created during petroleum refinement and is distributed via transfer facilities that may be located in densely populated areas. The health impacts from petcoke exposure to residents living in proximity to such facilities were evaluated for a petcoke transfer facilities located in Chicago, Illinois. Site-specific, margin of safety (MOS) and margin of exposure (MOE) analyses were conducted using estimated airborne and dermal exposures. The exposure assessment was based on a combined measurement and modeling program that included multiyear on-site air monitoring, air dispersion modeling, and analyses of soil and surfaces in residential areas adjacent to two petcoke transfer facilities located in industrial areas. Airborne particulate matter less than 10 microns (PM10) were used as a marker for petcoke. Based on daily fence line monitoring, the average daily PM10 concentration at the KCBX Terminals measured on-site was 32 μg/m(3), with 89% of 24-hr average PM10 concentrations below 50 μg/m(3) and 99% below 100 μg/m(3). A dispersion model estimated that the emission sources at the KCBX Terminals produced peak PM10 levels attributed to the petcoke facility at the most highly impacted residence of 11 μg/m(3) on an annual average basis and 54 μg/m(3) on 24-hr average basis. Chemical indicators of petcoke in soil and surface samples collected from residential neighborhoods adjacent to the facilities were equivalent to levels in corresponding samples collected at reference locations elsewhere in Chicago, a finding that is consistent with limited potential for off-site exposure indicated by the fence line monitoring and air dispersion modeling. The MOE based upon dispersion model estimates ranged from 800 to 900 for potential inhalation, the primary route of concern for particulate matter. This indicates a low likelihood of adverse health effects in the surrounding community. Implications: Handling of petroleum coke at

    Increasing demand for petroleum has stimulated industry to develop sustainable production of chemicals and biofuels using microbial cell factories. Fatty acids of chain lengths from C6 to C16 are propitious intermediates for the catalytic synthesis of industrial chemicals and diesel-like biofuels. The abundance of genetic information available for Escherichia coli and specifically, fatty acid metabolism in E. coli, supports this bacterium as a promising host for engineering a biocatalyst for the microbial production of fatty acids. Recent successes rooted in different features of systems metabolic engineering in the strain design of high-yielding medium chain fatty acid producing E. coli strains provide an emerging case study of design methods for effective strain design. Classical metabolic engineering and synthetic biology approaches enabled different and distinct design paths towards a high-yielding strain. Here we highlight a rational strain design process in systems biology, an integrated computational and experimental approach for carboxylic acid production, as an alternative method. Additional challenges inherent in achieving an optimal strain for commercialization of medium chain-length fatty acids will likely require a collection of strategies from systems metabolic engineering. Not only will the continued advancement in systems metabolic engineering result in these highly productive strains more quickly, this knowledge will extend more rapidly the carboxylic acid platform to the microbial production of carboxylic acids with alternate chain-lengths and functionalities.

  3. THE ROLE OF TIPPING IN REDUCING LABOUR COSTS: CASE OF SECTOR RETAIL PETROLEUM PRODUCTS

    2014-05-01

    Full Text Available The purpose of this paper was to determine whether tipping could reduce labour costs in the petroleum products retail sector. The research we present was designed on the basis of survey results gathered from Slovenian petrol stations in 2009 and 2010. We have identified the following factors in the tipping process: job satisfaction, flexibility, service quality, satisfaction, motivation and the factor of receiving tips. The analysis showed correlation between methods used to increase the value of tips and better service quality, increased financial and numerical flexibility, motivation, satisfaction upon receipt of tips and the method used to increase the value of tips. In order to decrease labour costs we propose that the management take control of tipping and integrates tips into the reward system. Also, the employees should be made aware about how tipping improves service and increases their income.

    Full Text Available The high economic growth in the past few years and increasing industrialization coupled with a burgeoning population have created a lot of concern for India’s energy scenario. India’s crude oil production has not shown significant growth in the last 10 or more years whereas its refining capacity has grown by more than 20% over the last 5 years. Oil consumption is growing at approximately 4.1% per year and natural gas consumption is growing at 68% per year. Therefore, evaluation performances and pushing energy companies to improve become important issues. The purpose of this research is of evaluation the performance of Indian energy industry under multiple different inputs and outputs criteria. The data envelopment analysis (DEA and grey theory are used to conduct this study. There are total 14 public sector undertakings (PSUs under this industry and no any private company. However, only 10 of them are mature enough to be published in India stock markets. Therefore, the realistic data of all 10 companies are used for this evaluation. The results demonstrate that Gas Authority of India Limited (GAIL, Chennai Petroleum Corporation Limited (CPCL, and Oil India Limited (OIL are the top 3 of ranking influences. This integrated numerical study gives a better “past-present-future” insights into evaluation performance in India energy industry.

    Hill Air Force Base (AFB) tested several conventional and innovative approaches to develop a cleanup strategy for a jet-fuel release to soil and groundwater at its petroleum, oil, and lubricant (POL) tank farm site. The technologies applied at the site include bioventing, skimming and sorbent-removal of light, nonaqueous-phase liquid (LNAPL), and vacuum-assisted free-product recovery (bioslurping). Detailed field investigation and numerical contaminant transport modeling using BIOPLUME II{reg_sign} documented intrinsic remediation as a viable cleanup alternatives for the dissolved-phase contamination. Based on field treatability studies, bioslurping was not as attractive an option as a combination of LNAPL recovery and bioventing to reduce the mass of contaminants in the source at this site. Evaluation of site geochemical data indicated biodegradation occurs through intrinsic processes including aerobic respiration, denitrification, iron reduction, sulfanogenesis, and methanogenesis. The modeling effort concluded that the contamination could be naturally attenuated within 13 years provided there was minimal source removal.

    Full Text Available Industrialization is highly desirable for the sustenance of a nation’s economy and the enhancement of the citizenry’s well being. However the negative impact precipitated by introduction of its unwanted by – products into ecological system may be catastrophic if allowed to build up and uncontrolled. Urban Air pollution due to activities of process industries is one of the main problems faced by the industrial area of the world. Experimental analysis was carried out on gas flare to determine the extent of air pollution by the petroleum refinery industry on the concentrations of NO, CO, SO2 and total hydrocarbon. Attempt at the modeling pollutant concentration from the flare point using visual basic is hereby presented. The model equation was used to simulate the concentration of pollutants at distance of 20, 40, 60, and 80, 100, to 1000 away from the flare point. The result of the simulation of model developed from the modified principle of gaseous dispersion by Gaussian showed a good agreement with the experimental results with average correction coefficient of 0.99. Results obtained reveled that the concentration of pollutants are unacceptable compare to the Federal Environmental protection Agency set limit. The dispersion pattern of pollutants showed that the extent of spreading is dependent on nearness to the source of flare, wind speed, temperature etc.

  1. Damage-Tolerant Fan Casings for Jet Engines

    Science.gov (United States)

    2006-01-01

    All turbofan engines work on the same principle. A large fan at the front of the engine draws air in. A portion of the air enters the compressor, but a greater portion passes on the outside of the engine this is called bypass air. The air that enters the compressor then passes through several stages of rotating fan blades that compress the air more, and then it passes into the combustor. In the combustor, fuel is injected into the airstream, and the fuel-air mixture is ignited. The hot gasses produced expand rapidly to the rear, and the engine reacts by moving forward. If there is a flaw in the system, such as an unexpected obstruction, the fan blade can break, spin off, and harm other engine components. Fan casings, therefore, need to be strong enough to contain errant blades and damage-tolerant to withstand the punishment of a loose blade-turned-projectile. NASA has spearheaded research into improving jet engine fan casings, ultimately discovering a cost-effective approach to manufacturing damage-tolerant fan cases that also boast significant weight reduction. In an aircraft, weight reduction translates directly into fuel burn savings, increased payload, and greater aircraft range. This technology increases safety and structural integrity; is an attractive, viable option for engine manufacturers, because of the low-cost manufacturing; and it is a practical alternative for customers, as it has the added cost saving benefits of the weight reduction.

    Science.gov (United States)

    Young, Eileen

    The underrepresentation of women in science, technology, engineering and mathematics (STEM) college programs is a troublesome local, national and global phenomenon. The topic of this doctoral thesis specifically focused on the underrepresentation of women in the field of engineering and more specifically on the factors that women may perceive as chiefly motivating them to choose engineering as a college major. By not choosing to major in engineering, women forego intellectual opportunities and the financial rewards that engineering careers can provide. Their absence means that the field of engineering also suffers from the lack of contributions from a diverse workforce. Women who graduated from a specific community college's engineering program in the United States were the focus of this qualitative study. Grounded in achievement motivation theory, and in particular expectancy-value theory of academic and career choice, this research was guided by two questions: How do women perceive their academic self-efficacies and expectations for success as influencing their decisions to enroll in engineering? How do women perceive their subjective task values as influencing their decisions to enroll in engineering? This single, holistic case study with one main unit of analysis incorporated a written questionnaire, individual interviews and a focus group meeting as the three instruments used to collect data. The qualitative data, cyclically coded, shed light on the complex mechanisms of academic and career choice.

    Adoption of advanced automated SE (ASE) tools would be more favored if a business case could be made that these tools are more valuable than alternate methods. In theory, software prediction models can be used to make that case. In practice, this is complicated by the 'local tuning' problem. Normally. predictors for software effort and defects and threat use local data to tune their predictions. Such local tuning data is often unavailable. This paper shows that assessing the relative merits of different SE methods need not require precise local tunings. STAR 1 is a simulated annealer plus a Bayesian post-processor that explores the space of possible local tunings within software prediction models. STAR 1 ranks project decisions by their effects on effort and defects and threats. In experiments with NASA systems. STARI found one project where ASE were essential for minimizing effort/ defect/ threats; and another project were ASE tools were merely optional.

    Full Text Available Petroleum has been and still remains, in equal measure, a friend and an enemy to humanity: a friend for its use in numerous applications over the years, from the lubrication of cart axles to jet fuel; an enemy for creating permanent conflicts between countries, leading to a global conflagration. This layout has perpetuated for over two millennia, until today.The problem of petroleum has a multitude of aspects: economic, political, financial, social, military, legislative and, last but not least, scientific and technical. It has taken a share of sacrifices, which may not be overlooked, to be rightfully called “black gold.” Subject to continuous development, petroleum is still indispensable to our quotidian life, although attempts have been made to replace it with alternative energy sources due to its negative effects on the planet, which are increasingly visible.The present state of petroleum industry is the result of a continuous labor of many generations of researchers, professors, engineers, technicians, foremen, and workers, especially from petroleum producing countries.  Romania is one of the first petroleum producers and ranked first in Europe and among the first nations worldwide until the end of the 19th century.  During the 20th century, a large number of oil and gas reservoirs were discovered in many countries on all continents; even today Romania still remains an important producer with encouraging perspectives.Romanian contributions to the progress of petroleum industry are noticeable, being appreciated and implemented by the major companies worldwide.  This work intends to present just several of these contributions, some of which are highlighted and highly regarded.

    to the problem-need specified in the beginning of the project, but producing a novel formulation (chemical product design) represents a method that results to a completely xylene-free process which is environmentally and economically more interesting than those generated via the more traditional process......Three solutions for removing the dangerous volatile organic compound (VOC) xylene from an industrial coating process are presented and compared. Two of them are based on classical process engineering principles, i.e., development of separation-cleaning methods such as incineration and adsorption....... The last approach is somewhat different and is based on the so-called product engineering concept, i.e., in this case, a change of the formulation so that xylene is entirely eliminated from the process. It is shown that both the process and the product engineering approaches yield viable solutions...

    Full Text Available A microbiological assessment of soil polluted by refined petroleum was carried out in Eluama community, Isuikwuato LGA, Abia State, Nigeria between March and October, 2012. The aim of the study is to examine the long-term kinetics of refined petroleum oil contaminated soil in this area from pipeline vandalization in the year 2000 and to assess the extent of biodegradation with respect to length of time of the spill. The microbiological examination of the soil samples were conducted by serial diluting and then inoculating the soil samples on different growth media. Several microbiological and biochemical methods were applied in order to isolate and identify the microorganisms accustomed to the soil sample. An unpolluted farmland served as control. Results showed a decrease in microbial load of soil as distance approaches seepage area. The control has a total heterotrophic bacteria count of 22.3 x 106 CFU/ml which decreases towards the seepage area (4.1 x 106 CFU/ml. The total fungi count also decreases from the control (5.9 x 106 CFU/ml towards the seepage area (1.2 x 106 CFU/ml. Micococcus sp and Pseudomonas aeroginosa were predominant in the seepage area up to 30m away from the seepage area. Other bacteria identified after this distance include Bacillus sp, Klebsiella pneumonia, Streptomyces sp, Streptococcus sp and Staphylococcus aureus while the predominant fungi were Aspergillus niger and Mucor sp. The marked decrease of heterotrophic bacteria and fungi in the petroleum polluted area compared with the control (the unpolluted farmland shows the unsuitability of the soil for agricultural purpose, as full remediation has not taken place.

    One of the huge concerns on the higher engineer education is the lag of real cases study that the future professionals need in the work and corporation market. This concern was reflected in Bologna higher education system including recommendations in this respect. The knowhow as why this or other methodology is one of the keys to resolve this problem. In the last courses given in Department of Crop Production, at the Agronomy Engineer School of Madrid (Escuela Técnica Superior de Ingenieros Agrónomos, UPM) we have developed more than one hundred applications in Microsoft Excel®. Our aim was to show different real scenarios which the future Agronomic Engineers can be found in their professional life and with items related to crop production field. In order to achieve our target, each application in Excel presents a file text in which is explained the theoretical concepts and the objectives, as well as some resources used from Excel syntax. In this way, the student can understand and use of such application, even they can modify and customize it for a real case presented in their context and/or master project. This electronic monograph gives an answer to the need to manage data in several real scenarios showed in lectures, calculus resolution, information analysis and manage worksheets in a professional and student level.

    The theory and practice of information engineering is being actively developed at Sandia National Laboratories. The main output of Sandia is information. Information is created, analyzed and distributed. It is the life blood of our design laboratory. The proper management of information will have a large, positive impact on staff productivity. In order to achieve the potential benefits of shared information a commonly understood approach is needed, and the approach must be implemented in a CASE (Computer-Aided Software Engineering) tool that spans the entire life cycle of information. The commonly understood approach used at Sandia is natural language. More specifically, it is a structured subset of English. Users and system developers communicate requirements and commitments that they both understand. The approach is based upon NIAM (Nijssen's Information Analysis Methodology). In the last three years four NIAM training classes have been given at Sandia. The classes were all at the introductory level, with the latest class last October having an additional seminar highlighting successful projects. The continued growth in applications using NIAM requires an advanced class. The class will develop an information model for the Ultimate CASE Tool.'' This paper presents the requirements that have been established for the Ultimate CASE Tool'' and presents initial models. 4 refs., 1 tab.

    A case study was conducted during 1994-2013 on several groups of process engineering students to see what was needed to transform a single course from a teacher-centred to a student-centred learning environment (SCLE). Development work was done incrementally, using Herbart's didactic triangle as a theoretical framework. The effects of the changes in learning environment were analysed using quantitative (student attendance, pass rate, attrition, grades) and qualitative data (student feedback). Guiding the didactic relation, i.e. the studying done by students, by continuous assessment was found to be very useful. Using SCLEs that emphasise student responsibility and activity in learning has been found in this case to enhance student learning considerably.

    Since the physical and chemical characteristics of biogas, some problems such as slow combustion speed, uncompleted burned fuel and high exhaust temperature will occur in its applications in engine. The biogas engine model library was built with the object-oriented language Modelica, the performance of a four-stroke spark-ignition gas engine operating with natural gas/liquefied petroleum gas-biogas blends were investigated. Natural gas (33 %, 67 % and 100%) and liquefied petroleum gas (5%, 10% and 15%) were added to the biogas and were simulated as the fuel of SI engine. The effects of natural gas/liquefied petroleum gas-biogas blends on the performance of spark-ignition engine used for electricity production were numerical investigated, the results were validated through the experiments on a gasoline modified gas engine. The results suggest that: There is an improvement in brake thermal efficiency and brake powers with the addition of natural gas/liquefied petroleum gas in biogas. The feature of reusable and object-orien-ted of Modelica will enhance the modeling and simulation of biogas engine performance greatly not only in accuracy but simulation efficiency, this would be efficient for the design and the optimum work of the biogas fuelled engine.%针对由沼气成分及其理化特性导致的内燃机燃用沼气时会发生燃烧速度慢、后燃严重、排气温度高等问题,将生物质燃气内燃机作为研究对象,基于可重用性及面向对象的Modelica语言建立内燃机模型库,将生物质燃气为燃料对四缸四冲程火花点火内燃机性能进行分析.通过仿真研究不同比例天然气(体积分数分别为33%,67%及100%)和LPG(体积分数分别为5%,10%及15%)对内燃机性能的影响,并在一台原汽油机改装的生物质燃气内燃机进行实验验证.结果表明:随着天然气/LPG的加入,内燃机的热效率及功率有所提高,且随着生物质燃气中天然气/LPG体积分数的增加,内

    The objective of this project was to isolate and characterize thermophilic bacterial cultures that can be used for the selective removal of nitrogen, sulfur, and/or metals in the biorefining of petroleum. The project was completed on schedule and no major difficulties were encountered. Significant progress was made on multiple topics relevant to the development of a petroleum biorefining process capable of operating at thermophilic temperatures. New cultures capable of selectively cleaving C-N or C-S bonds in molecules relevant to petroleum were obtained, and the genes encoding the enzymes for these unique biochemical reactions were cloned and sequenced. Genetic tools were developed that enable the use of Thermus thermophilus as a host to express any gene of interest, and information was obtained regarding the optimum conditions for the growth of T. thermophilus. The development of a practical biorefining process still requires further research and the future research needs identified in this project include the development of new enzymes and pathways for the selective cleavage of C-N or C-S bonds that have higher specific activities, increased substrate range, and are capable of functioning at thermophilic temperatures. Additionally, there is a need for process engineering research to determine the maximum yield of biomass and cloned gene products that can be obtained in fed-batch cultures using T. thermophilus, and to determine the best configuration for a process employing biocatalysts to treat petroleum.

    Full Text Available Genetic engineering (GE offers an expanding array of strategies for enhancing disease resistance of crop plants in sustainable ways, including the potential for reduced pesticide usage. Certain GE applications involve transgenesis, in some cases creating a metabolic pathway novel to the GE crop. In other cases, only cisgenessis is employed. In yet other cases, engineered genetic changes can be so minimal as to be indistinguishable from natural mutations. Thus, GE crops vary substantially and should be evaluated for risks, benefits, and social considerations on a case-by-case basis. Deployment of GE traits should be with an eye towards long-term sustainability; several options are discussed. Selected risks and concerns of GE are also considered, along with genome editing, a technology that greatly expands the capacity of molecular biologists to make more precise and targeted genetic edits. While GE is merely a suite of tools to supplement other breeding techniques, if wisely used, certain GE tools and applications can contribute to sustainability goals.

    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.

  13. Ethical considerations in tissue engineering research: Case studies in translation.

    Baker, Hannah B; McQuilling, John P; King, Nancy M P

    2016-04-15

    Tissue engineering research is a complex process that requires investigators to focus on the relationship between their research and anticipated gains in both knowledge and treatment improvements. The ethical considerations arising from tissue engineering research are similarly complex when addressing the translational progression from bench to bedside, and investigators in the field of tissue engineering act as moral agents at each step of their research along the translational pathway, from early benchwork and preclinical studies to clinical research. This review highlights the ethical considerations and challenges at each stage of research, by comparing issues surrounding two translational tissue engineering technologies: the bioartificial pancreas and a tissue engineered skeletal muscle construct. We present relevant ethical issues and questions to consider at each step along the translational pathway, from the basic science bench to preclinical research to first-in-human clinical trials. Topics at the bench level include maintaining data integrity, appropriate reporting and dissemination of results, and ensuring that studies are designed to yield results suitable for advancing research. Topics in preclinical research include the principle of "modest translational distance" and appropriate animal models. Topics in clinical research include key issues that arise in early-stage clinical trials, including selection of patient-subjects, disclosure of uncertainty, and defining success. The comparison of these two technologies and their ethical issues brings to light many challenges for translational tissue engineering research and provides guidance for investigators engaged in development of any tissue engineering technology.

    2015-05-01

    Full Text Available Mining engineering involves the design, planning and management of operations for the development, production and eventual rehabilitation of resource extraction. These activities draw on a diverse set of skills. University of British Columbia mining engineers have traditionally been highly regarded for their strengths in the technical aspects of mining and mineral process but also for their understanding of the application of principles of sustainability and social responsibility. The current view of the UBC Mining curriculum demands the integration of aspects of environmental and social sciences shaping the future of tertiary engineering education. The solution is developing a curriculum that is focused on key learning objectives that are a reflection of all these external pressures. This paper examines the challenge of curriculum reform and the emergence of learning communities at the Norman B. Keevil Institute of Mining Engineering at the University of British Columbia, Canada.

    2009-02-01

    Full Text Available A major challenge in engineering education is retaining student interest in the engineering discipline. Active student involvement in engineering projects is one way of retaining student interest. Such involvement can only be realized if project inception comes entirely from the student. This paper presents a software game, RMU Monopoly, developed as a project requirement for a software engineering course and describes the challenges and gains of implementing such a project. The RMU Monopoly was proposed by three junior software engineering students. The game is a multi-platform software program that allows up to eight players and implements the rules of the Monopoly board game. To ensure agility the game was developed using the spiral software development model. The Software Requirements Specification (SRS document was finalized through an iterative procedure. Standard Unified Modeling Language (UML diagrams were used for product design. A Risk Mitigation, Monitoring, and Management Plan (RMMM was developed to ensure proactive risk management. Gantt chart, weekly progress meetings and weekly scrum meetings were used to track project progress. C# and Sub- Version were used in a client-server architecture to develop the software. The project was successful in retaining student interest in the software engineering discipline

    2012-10-15

    The purpose of this report is to summarise the findings of the scientific and technical work undertaken by CONCAWE to assess the feasibility and potential benefit of characterising petroleum UVCB substances (Substances of Unknown or Variable Composition, Complex reaction products or Biological Materials) beyond the recommendations issued by CONCAWE for the substance identification of petroleum substances under REACH. REACH is the European Community Regulation on chemicals and their safe use (EC 1907/2006). It deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The report is based on Member Company experience of the chemical analysis of petroleum UVCB substances, including analysis in support of REACH registrations undertaken in 2010. This report is structured into four main sections, namely: Section 1 which provides an introduction to the subject of petroleum UVCB substance identification including the purpose of the report, regulatory requirements, the nature of petroleum UVCB substances, and CONCAWE's guidance to Member Companies and other potential registrants. Section 2 provides a description of the capabilities of each of the analytical techniques described in the REACH Regulation. This section also includes details on the type of analytical information obtained by each technique and an evaluation of what each technique can provide for the characterisation of petroleum UVCB substances. Section 3 provides a series of case studies for six petroleum substance categories (low boiling point naphthas, kerosene, heavy fuel oils, other lubricant base oils, residual aromatic extracts and bitumens) to illustrate the value of the information derived from each analytical procedure, and provide an explanation for why some techniques are not scientifically necessary. Section 4 provides a summary of the conclusions reached from the technical investigations undertaken by CONCAWE Member Companies, and summarising the

  14. Signal Analysis of Automotive Engine Spark Ignition System using Case-Based Reasoning (CBR) and Case-based Maintenance (CBM)

    Science.gov (United States)

    Huang, H.; Vong, C. M.; Wong, P. K.

    2010-05-01

    With the development of modern technology, modern vehicles adopt electronic control system for injection and ignition. In traditional way, whenever there is any malfunctioning in an automotive engine, an automotive mechanic usually performs a diagnosis in the ignition system of the engine to check any exceptional symptoms. In this paper, we present a case-based reasoning (CBR) approach to help solve human diagnosis problem. Nevertheless, one drawback of CBR system is that the case library will be expanded gradually after repeatedly running the system, which may cause inaccuracy and longer time for the CBR retrieval. To tackle this problem, case-based maintenance (CBM) framework is employed so that the case library of the CBR system will be compressed by clustering to produce a set of representative cases. As a result, the performance (in retrieval accuracy and time) of the whole CBR system can be improved.

    Glenn R. Gaudette

    2012-01-01

    Full Text Available In a biomedical engineering lab at Worcester Polytechnic Institute, co-author Dr. Glenn R. Gaudette and his research team are investigating the effects of stem cell therapy on the regeneration of function in damaged cardiac tissue in laboratory rats. Each instance of stem cell experimentation on a rat yields hundreds of data sets that must be carefully captured, documented and securely stored so that the data will be easily accessed and retrieved for papers, reports, further research, and validation of findings, while meeting NIH guidelines for data sharing. After a brief introduction to the bioengineering field and stem cell research, this paper focuses on the experimental workflow and the data generated in one instance of stem cell experimentation; the lab’s data management practices; and how Dr. Gaudette teaches data management to the lab’s incoming graduate students each semester. The co-authors discuss the haphazard manner by which engineering and science students typically learn data management practices, and advocate for the integration of formal data management instruction in higher education STEM curricula. The paper concludes with a discussion of the Frameworks for a Data Management Curriculum developed collaboratively by the co-authors’ institutions -- the University of Massachusetts Medical School and Worcester Polytechnic Institute -- to teach data management best practices to students in the sciences, health sciences, and engineering.

    Oil companies rarely carry out themselves the important works planned in the framework of their investments or of the exploitation of their facilities. In most cases, they act as prime contractor and generate a huge market of equipments, services and engineering needs in which many companies of various size are involved and make the overall para-petroleum industry. The French position on this market was asserted very early thanks to the continuation of ambitious R and D programs, very often carried out in the framework of the CEP and M and of the COPREP, which have permitted to build and maintain a solid technological knowledge. In this context, the lack of regular statistical data about the French para-petroleum industry has led, since 1978, the group of para-petroleum and para-gas companies, the CEP and M and the former COPREP (now the Committee of petroleum and marine studies - CEP and M), and the French institute of petroleum (IFP), to launch an annual inquiry at the national scale. This document makes a brief overview of the international context of the petroleum industry and then presents the last results of the 2004 inquiry about the French para-petroleum industry. Some data are foreseen for 2005, based on the estimations supplied by the companies themselves. (J.S.)

    This report studies the factors hindering increased utilization of associated petroleum gas (APG) in Russia. The issue of flaring versus utilization is studied from a Technology Innovation System (TIS) perspective, seeing the non-utilization issue as a problem of technology diffusion. There are many technological options available for APG utilization, but a main blocking mechanism in the Russian case is the Gazprom monopoly on gas transportation via their pipelines. A commonly discussed solution is policy to ensure third party access, but this study finds that this solution holds little potential, as its ramifications are too extensive and unacceptable to the key actor Gazprom. More promising solutions may be found in small, emerging engineering companies. (Author)

    2010-09-01

    Full Text Available Reverse logistics has gained increasing attention in recent years as a channel for companies to achieve operational excellence. The process involves manipulation of returned materials, or even products, which forms a pivotal role in sustainable development throughout the whole supply chains. To make reverse logistics possible, process re-engineering may need to be carried out. However, the processes involved in reengineering are practically complicated. Objectives, benefits, and applicability of any process re-engineering require a careful and detailed strategic planning. This paper aims to propose an easy-to-follow step-by-step framework for practitioners to perform process re-engineering, to learn and identify the critical issues in each step, and to be successful in applying process re-engineering in order to enhance reverse logistics performance. A learner-centred approach is adopted based on a case study of process re-engineering, which is demonstrated in the paper for explanation.

This paper introduces the definition of cloud drilling and its differentiation from the existing drilling model. Cloud drilling system is composed of cloud-providing terminal, cloud requester and cloud drilling platform. The conifguration of the system includes physical resources zone, service zone and application zone. The services model is divided into infrastructure service, cloud platform service and cloud software service. The service platform is managed in three patterns–public cloud, private cloud and mixed cloud–and characterized with IOT, virtualization, service standardization, coordination and intelligence. The paper also comes up with suggestions on study and development of oil engineering technology for cloud drilling, manufacture of equipment, and adoption of intelligent solutions.

  14. Linking biomedical engineering ethics case study approach and policy.

    Science.gov (United States)

    Dibrell, William; Dobie, Elizabeth Ann

    2007-01-01

    In this paper we link bioengineering case study methods to the development of policy. The case study approach to ethics is an excellent way to show the complex nature of practical/moral reasoning. This approach can, however, lead to a kind of overwhelming complexity. The individual nature of each case makes it difficult to identify the most important information and difficult to see what moral considerations are most relevant. In order to make the overwhelming complexity less debilitating, we present a framework for moral decision making derived from suggestions made by W.D. Ross and Virginia Held. Ross articulates the multiple sources of morality and Held deepens the discussion by reminding us of the foundational importance of care and sympathy to our moral natures. We show how to use the notion of prima facie duty and discuss moral conflict. In doing this, we show how the framework, applied to cases, can be of assistance in helping us develop policies and codes of ethics with sufficient plasticity to be useful in the complex world of the bioengineer.

  20. Using Student Video Cases to Assess Pre-service Elementary Teachers' Engineering Teaching Responsiveness

    Dalvi, Tejaswini; Wendell, Kristen

    2016-10-01

    Our study addresses the need for new approaches to prepare novice elementary teachers to teach both science and engineering, and for new tools to measure how well those approaches are working. This in particular would inform the teacher educators of the extent to which novice teachers are developing expertise in facilitating their students' engineering design work. One important dimension to measure is novice teachers' abilities to notice the substance of student thinking and to respond in productive ways. This teacher noticing is particularly important in science and engineering education, where students' initial, idiosyncratic ideas and practices influence the likelihood that particular instructional strategies will help them learn. This paper describes evidence of validity and reliability for the Video Case Diagnosis (VCD) task, a new instrument for measuring pre-service elementary teachers' engineering teaching responsiveness. To complete the VCD, participants view a 6-min video episode of children solving an engineering design problem, describe in writing what they notice about the students' science ideas and engineering practices, and propose how a teacher could productively respond to the students. The rubric for scoring VCD responses allowed two independent scorers to achieve inter-rater reliability. Content analysis of the video episode, systematic review of literature on science and engineering practices, and solicitation of external expert educator responses establish content validity for VCD. Field test results with three different participant groups who have different levels of engineering education experience offer evidence of construct validity.

    Crude oil refining is an industrial activity known as very pollutant, as all other activities of the petroleum industry, regarding either the volume or the concentration of the resides involved, thus generating emissions, effluents and solid wastes. The aim of the present work is to study solid waste management of a certain petroleum refinery, located in Rio de Janeiro. On the solid wastes management of that refinery, the following aspects were considered: origin and period of generation, conditioning, storage, transportation, treatment and final disposal. After listing all the resides and through analysis of the industrial wastes (norms, terms, inventory), the industrial process and office routines were then analyzed. The solid wastes were divided in two categories: industrial and administrative wastes. As far as destination is concerned, resides classified as Class I are either co-processed or incinerated, while Class II and Class III wastes, when not recycled, are sent to industrial or sanitary landfill. Finally, after analyzing the wastes management of the refinery, it has been proposed a plan of achievements in order to enhance the environmental goal of the refinery. (author)

    2010-07-01

    Full Text Available As Data Mining for Secure Software Engineering improves software productivity and quality, software engineers are increasingly applying data mining algorithms to various software engineering tasks. However mining software engineering data poses several challenges, requiring various algorithms to effectively mine sequences, graphs and text from such data. Software engineering data includes code bases, execution traces, historical code changes,mailing lists and bug data bases. They contains a wealth of information about a projects-status, progress and evolution. Using well established data mining techniques, practitioners and researchers can explore the potential of this valuable data in order to better manage their projects and do produce higher-quality software systems that are delivered on time and with in budget. Data mining can be used in gathering and extracting latent security requirements, extracting algorithms and business rules from code, mining legacy applications for requirements and business rules for new projects etc. Mining algorithms for software engineering falls into four main categories: Frequent pattern mining – finding commonly occurring patterns; Pattern matching – finding data instances for given patterns; Clustering – grouping data into clusters and Classification – predicting labels of data based on already labeled data.

    Clark, Robin; Andrews, Jane

    2014-11-01

    This paper begins with the argument that within modern-day society, engineering has shifted from being the scientific and technical mainstay of industrial, and more recently digital change to become the most vital driver of future advancement. In order to meet the inevitable challenges resulting from this role, the nature of engineering education is constantly evolving and as such engineering education has to change. The paper argues that what is needed is a fresh approach to engineering education - one that is sufficiently flexible so as to capture the fast-changing needs of engineering education as a discipline, whilst being pedagogically suitable for use with a range of engineering epistemologies. It provides an overview of a case study in which a new approach to engineering education has been developed and evaluated. The approach, which is based on the concept of scholarship, is described in detail. This is followed by a discussion of how the approach has been put into practice and evaluated. The paper concludes by arguing that within today's market-driven university world, the need for effective learning and teaching practice, based in good scholarship, is fundamental to student success.

    Rupp, Madeline

    The following master's thesis is composed of two manuscripts describing STEM teachers' orientations to science teaching through engineering within the context of the Science Learning through Engineering Design (SLED) partnership. The framework guiding both studies was science teaching orientations, a component of pedagogical content knowledge. Data were collected via semi-structured interviews, multi-day classroom observations, pre- and post-observation interviews, implementation plans, and written reflections. Data sources were analyzed to generate two orientations to science teaching through engineering design for each participant. The first manuscript illustrates a single case study conducted with a sixth grade STEM teacher. Results of this study revealed a detailed picture of the teacher's goals, practices, assessments, and general views when teaching science through engineering design. Common themes across the teacher's instruction were used to characterize her orientations to science teaching through engineering design. Overall, the teacher's orientations showed a shift in her practice from didactic to student-centered methods of teaching as a result of integrating engineering design-based curriculum. The second manuscript describes a comparative case study of two sixth grade SLED participants. Results of this study revealed more complex and diverse relationships between the teachers' orientations to teaching science through engineering design and their instruction. Participants' orientations served as filters for instruction, guided by their divergent purposes for science teaching. Furthermore, their orientations and resulting implementation were developed from knowledge gained in teacher education, implying that teacher educators and researchers can use this framework to learn more about how teachers' knowledge is used to integrate engineering and science practices in the K-12 classroom.

  3. Preferential Petroleum Migration Pathways in Eastern Pearl River Mouth Basin,Offshore South China Sea

    2009-01-01

    Secondary petroleum migration in the eastern Pearl River Mouth basin was modeled using the three-dimensional PATHWAYSTM model,which assumes that the positions of petroleum migration pathways are controlled by the morphology of the sealing surfaces.The modeling results have accurately predicted the petroleum occurrences.Most commercial petroleum accumulations are along the predicted preferential petroleum migration pathways (PPMP),and most large fields (petroleum reserves greater than 1×108 t) have more than one preferential petroleum migration pathways to convey petroleum to the traps.The lateral migration distance for oil in the LH11-1 field,the largest oilfield so far discovered in the Pearl River Mouth basin,was more than 80 km.The case study suggests that in lacustrine fault basins,petroleum can migrate over a long distance to form large oilfields without driving force from groundwater flow.The focusing of petroleum originating from a large area of the generative kitchens into restricted channels seems to be essential not only for long-range petroleum migration in hydrostatic conditions,but also for the formation of large oil or gas fields.The strong porosity and permeability heterogeneities of the carrier beds and the relatively high prediction accuracy by a model that does not take into consideration of the effect of heterogeneity suggest that the positions of petroleum migration pathways in heterogeneous carrier beds with relatively large dipping angles are determined primarily by the morphology of the sealing surfaces at regional scales.

  4. Irreversibilities and efficiency at maximum power of heat engines: the illustrative case of a thermoelectric generator.

    2012-03-01

    Energy conversion efficiency at maximum output power, which embodies the essential characteristics of heat engines, is the main focus of the present work. The so-called Curzon and Ahlborn efficiency η(CA) is commonly believed to be an absolute reference for real heat engines; however, a different but general expression for the case of stochastic heat engines, η(SS), was recently found and then extended to low-dissipation engines. The discrepancy between η(CA) and η(SS) is here analyzed considering different irreversibility sources of heat engines, of both internal and external types. To this end, we choose a thermoelectric generator operating in the strong-coupling regime as a physical system to qualitatively and quantitatively study the impact of the nature of irreversibility on the efficiency at maximum output power. In the limit of pure external dissipation, we obtain η(CA), while η(SS) corresponds to the case of pure internal dissipation. A continuous transition between from one extreme to the other, which may be operated by tuning the different sources of irreversibility, also is evidenced.

    Petroleum hydrocarbon pollutants are recalcitrant compounds and are classified as priority pollutants. Cleaning up of these pollutants from environment is a real world problem. Bioremediation has become a major method employed in restoration of petroleum hydrocarbon polluted environments that makes use of natural microbial biodegradation activity. Petroleum hydrocarbons utilizing microorganisms are ubiquitously distributed in environment. They naturally biodegrade pollutants and thereby remove them from the environment. Removal of petroleum hydrocarbon pollutants from environment by applying oleophilic microorganisms (individual isolate/consortium of microorganisms) is ecofriendly and economic. Microbial biodegradation of petroleum hydrocarbon pollutants employs the enzyme catalytic activities of microorganisms to enhance the rate of pollutants degradation. This article provides an overview about bioremediation for petroleum hydrocarbon pollutants. It also includes explanation about hydrocarbon metabolism in microorganisms with a special focus on new insights obtained during past couple of years.

    Pollock, Meagan C.

    richly describe the diversity of experiences. A multiple case study analysis, this study answers the question: How do gender, class, race, and other components of intersectionality, influence high school females' experiences in engineering? Nine young women taking a high school engineering course in a suburban high school in Central Texas during the school year 2011-2012 volunteered to participate. The students were observed in their engineering classes for half of the spring 2012 semester, with bi-weekly interviews with the students, monthly interviews with the teacher, and a single interview with a parent of each volunteer. The nine rich case studies provide us with new stories that help prevent us from narrowing the experiences of women to a single incomplete stereotype, because these young women vary across race, socioeconomic backgrounds, and sexual orientation. Although each story is unique, there are commonalities among their experiences, including family, influence, classroom environment, biases, and beliefs. By drawing from their collective experiences in high school engineering, the findings direct us toward recommendations for educators, parents, engineering curriculum developers, designers of teacher professional development, and future research to improve equity and access for every student in engineering.

    Full Text Available This article describes an action research project conducted at Los Alamos National Laboratory (LANL to resolve a problem with the ability of licensed and/or certified engineers to obtain the ethics-related professional development units or hours (PDUs or PDHs needed to maintain their credentials. Because of the recurring requirement and the static nature of the information, an initial, in-depth training followed by annually updated refresher training was proposed. A case model approach, with online delivery, was selected as the optimal pedagogical model for the refresher training. In the first two years, the only data that was collected was throughput and information retention. Response rates indicated that the approach was effective in helping licensed professional engineers obtain the needed PDUs. The rates of correct responses suggested that knowledge transfer regarding ethical reasoning had occurred in the initial training and had been retained in the refresher. In FY13, after completing the refresher, learners received a survey asking their opinion of the effectiveness and utility of the course, as well as their impressions of the case study format vs. the typical presentation format. Results indicate that the courses have been favorably received and that the case study method supports most of the pedagogical needs of adult learners as well as, if not better than, presentation-based instruction. Future plans for improvement are focused on identifying and evaluating methods for enriching online delivery of the engineering ethics cases.

This is now being extended to petroleum by building on the joint classification of the Society of Petroleum Engineers (SPE), the World Petroleum Congresses (WPC) and the American Association of Petroleum Geologists (AAPG). The UNFC is a 3-dimansional classification. This: Is necessary in order to migrate accounts of resource quantities that are developed on one or two of the axes to the common basis; Provides for more precise reporting and analysis. This is particularly useful in analyses of contingent resources. The characteristics of the SPE/WPC/AAPG classification has been preserved and enhanced to facilitate improved international and national petroleum resource management, corporate business process management and financial reporting. A UN intergovernmental committee responsible for extending the UNFC to extractive energy resources (coal, petroleum and uranium) will meet in Geneva on October 30th and 31st to review experiences gained and comments received during 2003. A recommended classification will then be delivered for consideration to the United Nations through the Committee on Sustainable Energy of the Economic Commission for Europe (UN ECE).

    2011-01-01

    Vibration mode shape description of an aero-engine casing structure using Zernike moment descriptor (ZMD) was introduced in this paper. The mode shapes of the aero-engine casing structure can be decomposed as a linear combination of a series of Zernike polynomials, with the feature of each Zernike polynomial reflecting a part of characteristic of mode shapes, based on Zernike moment transformation. Meanwhile, the reconstruction of mode shapes with ZMD was explored and its ability to filtering the noise contaminated in the mode shapes was studied. Simulation of the aero-engine casing structure indicated the advantage of this method to depict the mode shapes of a symmetric structure. Results demonstrate that the Zernike moment description of the mode shapes can effectively describe the double modes in the symmetric structure and also has the ability to remove or significantly reduce the influence of noise in the mode shapes. Such feature shows great practical value for further research on the correlation, model updating and model validation of the symmetric structure's finite element model.

    Full Text Available Electrical resistivity tomography (ERT is a non-invasive geophysical method of primary interest for addressing subsurface engineering problems. The method is based on the assumption that subsurface geological materials have significant resistivity contrasts that can be identified based on measurements on the surface. This paper presents three different case studies that have been carried out at different sites. The first case study visualizes the contrast between high resistivity zones of hard bedrocks and low resistivity zones of weathered rocks. Similar to the first case study, the second case study shows high resistivity contrasts that clearly distinguishes the shape of a footing located within the surrounding materials. The third case study shows no clear low resistivity zone that can be identified as a leaking zone. The 2D ERT survey method used in these three investigations has been shown to be useful as a cost-effective and rapid method to obtain wide area subsurface information that is relevant for subsurface engineering problems.

    Vielma, Karina I.

    Research points to the many obstacles that first-generation, Latina students face when attempting to enter fields in science, technology, engineering, and mathematics, STEM. This qualitative, case study examined the personal and educational experiences of first-generation Latina women who successfully navigated the STEM educational pipeline earning bachelor's, master's, and doctoral degrees in various fields of engineering. Three research questions guided the study: (1) How does a first-generation Latina engineer and scientist describe her life experiences as she became interested in STEM? (2) How does she describe her educational experiences as she navigated the educational pipeline in the physics, mathematics, and/or engineering field(s)? (3) How did she respond to challenges, obstacles and microaggressions, if any, while navigating the STEM educational pipeline? The study was designed using a combination of Critical Race Theory frameworks---Chicana feminist theory and racial microaggressions. Through a life history case study approach, the women shared their stories of success. With the participants' help, influential persons in their educational paths were identified and interviewed. Data were analyzed using crystallization and thematic results indicated that all women in this study identified their parents as planting the seed of interest through the introduction of mathematics. The women unknowingly prepared to enter the STEM fields by taking math and science coursework. They were guided to apply to STEM universities and academic programs by others who knew about their interest in math and science including teachers, counselors, and level-up peers---students close in age who were just a step more advanced in the educational pipeline. The women also drew from previous familial struggles to guide their perseverance and motivation toward educational degree completion. The lives of the women where complex and intersected with various forms of racism including

    2003-01-01

    Surface enhancement technologies such as shot peening, laser shock peening (LSP), and low plasticity burnishing (LPB) can provide substantial fatigue life improvement. However, to be effective, the compressive residual stresses that increase fatigue strength must be retained in service. For successful integration into turbine design, the process must be affordable and compatible with the manufacturing environment. LPB provides thermally stable compression of comparable magnitude and even greater depth than other methods, and can be performed in conventional machine shop environments on CNC machine tools. LPB provides a means to extend the fatigue lives of both new and legacy aircraft engines and ground-based turbines. Improving fatigue performance by introducing deep stable layers of compressive residual stress avoids the generally cost prohibitive alternative of modifying either material or design. The X-ray diffraction based background studies of thermal and mechanical stability of surface enhancement techniques are briefly reviewed, demonstrating the importance of minimizing cold work. The LPB process, tooling, and control systems are described. An overview of current research programs conducted for engine OEMs and the military to apply LPB to a variety of engine and aging aircraft components are presented. Fatigue performance and residual stress data developed to date for several case studies are presented including: * The effect of LPB on the fatigue performance of the nickel based super alloy IN718, showing fatigue benefit of thermal stability at engine temperatures. * An order of magnitude improvement in damage tolerance of LPB processed Ti-6-4 fan blade leading edges. * Elimination of the fretting fatigue debit for Ti-6-4 with prior LPB. * Corrosion fatigue mitigation with LPB in Carpenter 450 steel. *Damage tolerance improvement in 17-4PH steel. Where appropriate, the performance of LPB is compared to conventional shot peening after exposure to engine

    There is no doubt that Search Engines are playing a great role in Internet usage. But all the top search engines Google, Yahoo and Bing are having a critical flaw called "Openness of a Search Engine". An Internet user should be allowed to get the search results only when requested through Search engine's web page but the user must not be allowed to get the search results when requested through any web page that does not belong to the Search Engine. Only results of a search engine should be available to the Internet user but not the Search Engine. This paper explains the critical flaw called "Openness of Search Engine" with a case study on top 3 search engines 'Google', 'Yahoo' and 'Bing'. This paper conducts an attack based test using J2EE framework and proves that 'Google' passed the test and it strongly protects its Critical Search System, where 'Yahoo' and 'Bing' are failed to protect their Search Engines. But previously 'Google' also had other high severity issues with the Openness of search engine; this ...

  12. Re-Os geochronology and Os isotope fingerprinting of petroleum sourced from a Type I lacustrine kerogen: insights from the natural Green River petroleum system in the Uinta Basin and hydrous pyrolysis experiments

    2014-01-01

    Rhenium–osmium (Re–Os) geochronology of marine petroleum systems has allowed the determination of the depositional age of source rocks as well as the timing of petroleum generation. In addition, Os isotopes have been applied as a fingerprinting tool to correlate oil to its source unit. To date, only classic marine petroleum systems have been studied. Here we present Re–Os geochronology and Os isotope fingerprinting of different petroleum phases (oils, tar sands and gilsonite) derived from the lacustrine Green River petroleum system in the Uinta Basin, USA. In addition we use an experimental approach, hydrous pyrolysis experiments, to compare to the Re–Os data of naturally generated petroleum in order to further understand the mechanisms of Re and Os transfer to petroleum. The Re–Os geochronology of petroleum from the lacustrine Green River petroleum system (19 ± 14 Ma – all petroleum phases) broadly agrees with previous petroleum generation basin models (∼25 Ma) suggesting that Re–Os geochronology of variable petroleum phases derived from lacustrine Type I kerogen has similar systematics to Type II kerogen (e.g., Selby and Creaser, 2005a, Selby and Creaser, 2005b and Finlay et al., 2010). However, the large uncertainties (over 100% in some cases) produced for the petroleum Re–Os geochronology are a result of multiple generation events occurring through a ∼3000-m thick source unit that creates a mixture of initial Os isotope compositions in the produced petroleum phases. The 187Os/188Os values for the petroleum and source rocks at the time of oil generation vary from 1.4 to 1.9, with the mode at ∼1.6. Oil-to-source correlation using Os isotopes is consistent with previous correlation studies in the Green River petroleum system, and illustrates the potential utility of Os isotopes to characterize the spatial variations within a petroleum system. Hydrous pyrolysis experiments on the Green River Formation source rocks show that Re and Os transfer

    Recent discoveries and important oil shows have proven the existence of hydrocarbons in newly identified depocenters and reservoirs. In general, except for some areas around the producing fields, Tunisia is largely underdrilled. The national company ETAP has decided to release data and to publish a synthesis on the petroleum geology of Tunisia. The geology of Tunisia provides a fine example of the contrast between Alpine folding, which typifies northern Tunisia and the African craton area of the Saharan part. Eastern Tunisia corresponds to an unstable platform forming plains or low hills and extending eastwards to the shallow Pelagian Sea. There are a wide variety of basins: central and northern Tunisia represents a front basin the Saharan Ghadames basin or the Chott trough are sag basins; the Gulf of Gabes was formed as a distension margin the Gulf of Hammamet is a composite basin and several transversal grabens cut across the country, including offshore, and are rift-type basins. All these features are known to be oil prolific throughout the world. Two large fields and many modest-size pools are known in Tunisia. Oil and gas fields in the surrounding countries, namely the Saharan fields of Algeria and Libya the large Bouri field offshore Tripolitania and discoveries in the Italian part of the Straits of Sicily, suggest a corresponding potential in Tunisia. Exposed paleogeographic and structural maps, balanced sections, and examples of fields and traps will support an optimistic evaluation of the future oil exploration in Tunisia.

  18. The Strategic Petroleum Reserve: United States energy security, oil politics, and petroleum reserves policies in the twentieth century

    Science.gov (United States)

    Beaubouef, Bruce Andre

    The history of U.S. petroleum reserves policies in the twentieth century, including the Strategic Petroleum Reserve (SPR) program, provides a case study of the economic and political aspects of national security, and shows the ways in which the American political economy influences national security. One key problem plagued federal petroleum reserve programs and proposals throughout the twentieth century. In a political economy which traditionally placed strong emphasis upon the sanctity of private property and free markets, could the government develop an emergency petroleum reserve policy despite opposition from the private sector? Previous literature on the SPR and oil-stockpiling programs has largely disregarded the historical perspective, focusing instead upon econometric models, suggesting future oil-stockpiling policy options. This study will also make conclusions about the future of governmental oil-stockpiling policies, particularly with regard to the SPR program, but it will do so informed by a systematic history of the emergency petroleum reserve impulse in the twentieth century. Through a study of the emergency petroleum reserve impulse, one can see how the American political economy of oil and energy changed over the twentieth century. As petroleum became crucial to the military and then economic security of the United States, the federal government sought to develop emergency petroleum reserves first for the military, then for the civilian economy. But while the American petroleum industry could deliver the energy "goods" to American energy consumers at a reasonable price, the companies reigned supreme in the political equation. While that was true, federal petroleum reserve programs and proposals conflicted with and were overwhelmed by the historic American tradition of individual economic and private property rights. The depletion of American petroleum reserves changed that political equation, and the ensuing energy crises of the 1970s not only

    2009-04-01

    We present some analysis and conclusions from a case study of the culture and practices of scientists at the Met Office and Hadley Centre working on the development of software for climate and Earth System models using the MetUM infrastructure. The study examined how scientists think about software correctness, prioritize their requirements in making changes, and develop a shared understanding of the resulting models. We conclude that highly customized techniques driven strongly by scientific research goals have evolved for verification and validation of such models. In a formal software engineering context these represents costly, but invaluable, software integration tests with considerable benefits. The software engineering practices seen also exhibit recognisable features of both agile and open source software development projects - self-organisation of teams consistent with a meritocracy rather than top-down organisation, extensive use of informal communication channels, and software developers who are generally also users and science domain experts. We draw some general conclusions on whether these practices work well, and what new software engineering challenges may lie ahead as Earth System models become ever more complex and petascale computing becomes the norm.

    2012-12-01

    Meeting the increasing global demand for energy over the next several decades presents daunting challenges to engineers and scientists, including geoscientists of all disciplines. Many opportunities exist for geophysicists to find and produce oil and gas in a safe, environmentally responsible and affordable manner. Successful oil and gas exploration involves a 'Plates to Pores' approach that integrates multi-scale data from satellites, marine and land seismic and non-seismic field surveys, lab experiments, and even electron microscopy. The petroleum industry is at the forefront of using high performance computing to develop innovative methods to process and analyze large volumes of seismic data and perform realistic numerical modeling, such as finite element fluid flow and rock deformation simulations. Challenging and rewarding jobs in exploration, production and research exist for students with BS/BA, MS and PhD degrees. Geophysics students interested in careers in the petroleum industry should have a broad foundation in science, math and fundamental geosciences at the BS/BA level, as well as mastery of the scientific method, usually gained through thesis work at MS and PhD levels. Field geology or geophysics experience is also valuable. Other personal attributes typical for geoscientists to be successful in industry include a passion for solving complex geoscience problems, the flexibility to work on a variety of assignments throughout a career and skills such as teamwork, communication, integration and leadership. In this presentation we will give examples of research, exploration and production opportunities for geophysicists in petroleum companies and compare and contrast careers in academia vs. industry.

    The primary goal of the Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART) is to enable the design of revolutionary applications based on shape memory alloy (SMA) technology. In order to help realize this goal and reduce the development time and required experience for the fabrication of SMA actuation systems, several modeling tools have been developed for common actuator types and are discussed herein along with case studies, which highlight the capabilities and limitations of these tools. Due to their ability to sustain high stresses and recover large deformations, SMAs have many potential applications as reliable, lightweight, solid-state actuators. Their advantage over classical actuators can also be further improved when the actuator geometry is modified to fit the specific application. In this paper, three common actuator designs are studied: wires, which are lightweight, low-profile, and easily implemented; springs, which offer actuation strokes upwards of 200 at reduced mechanical loads; and torque tubes, which can provide large actuation forces in small volumes and develop a repeatable zero-load actuation response (known as the two-way shape memory effect). The modeling frameworks, which have been implemented in the design tools, are developed for each of these frequently used SMA actuator types. In order to demonstrate the versatility and flexibility of the presented design tools, as well as validate their modeling framework, several design challenges were completed. These case studies include the design and development of an active hinge for the deployment of a solar array or foldable space structure, an adaptive solar array deployment and positioning system, a passive air temperature controller for regulation flow temperatures inside of a jet engine, and a redesign of the Corvette active hatch, which allows for pressure equalization of the car interior.

    Evolutionary robotics (ER) is a powerful approach for the automatic synthesis of robot controllers, as it requires little a priori knowledge about the problem to be solved in order to obtain good solutions. This is particularly true for collective and swarm robotics, in which the desired behavior of the group is an indirect result of the control and communication rules followed by each individual. However, the experimenter must make several arbitrary choices in setting up the evolutionary process, in order to define the correct selective pressures that can lead to the desired results. In some cases, only a deep understanding of the obtained results can point to the critical aspects that constrain the system, which can be later modified in order to re-engineer the evolutionary process towards better solutions. In this article, we discuss the problem of engineering the evolutionary machinery that can lead to the desired result in the swarm robotics context. We also present a case study about self-organizing synchronization in a swarm of robots, in which some arbitrarily chosen properties of the communication system hinder the scalability of the behavior to large groups. We show that by modifying the communication system, artificial evolution can synthesize behaviors that scale properly with the group size.

    The prevalence of burns in the world is more than 800 cases per one million people each year and this is the second highest cause of death due to trauma after traffic accident. Many studies are turning to skin substitute methods of tissue engineering. The purpose of this study is to determine the composition of the collagen, chitosan, and lauric acid scaffold, as well as knowing the results of the characterization of the scaffold. The synthesis of chitosan collagen lauric acid scaffold as a skin tissue was engineered using freeze dried method. Results from making of collagen chitosan lauric acid scaffold was characterized physically, biologically and mechanically by SEM, cytotoxicity, biodegradation, and tensile strength. From the morphology test, the result obtained is that pore diameter size ranges from 94.11 to 140.1 µm for samples A,B,C,D, which are in the range of normal pore size 63-150 µm, while sample E has value below the standard which is about 37.87 to 47.36 µm. From cytotoxicity assay, the result obtained is the percentage value of living cells between 20.11 to 21.51%. This value is below 50% the standard value of living cells. Incompatibility is made possible because of human error mainly the replication of washing process over the standard. Degradation testing obtained values of 19.44% - 40% by weight which are degraded during the 7 days of observation. Tensile test results obtained a range of values of 0.192 - 3.53 MPa. Only sample A (3.53 MPa) and B (1.935 MPa) meet the standard values of skin tissue scaffold that is 1-24 MPa. Based on the results of the characteristics of this study, composite chitosan collagen scaffold with lauric acid plasticizer has a potential candidate for skin tissue engineering for skin burns cases.

    On the basis of diverse microfossils such as foraminifers, ostracods, micromulluscs, fossil spores and pollen and calcareous nannofossils derived from 14 drill holes, the sediments are divided into two part, the upper marine part and the lower nonmarine one. Marine part is subdivided into 4 foraminiferal zones and 3 nannofossil zones of Plio-Pleistocene age. In the lower part ranging from Oligocene to Late Miocene 4 palynomoph assemblages are established, which reflect climatic changes fluctuating between subtropical and cool temperate. Some fine sediments occurring in the South Sea continental shelf are rich in organic matter to be hydrocarbon source rock. The organic matter is mainly compared to type 3. However, lower part of the Geobuk-1 and Okdom-1 shows more oil prone geochemical characteristics than other wells. The kerosene is mixture type 1 and type 3 organic matter. The main oil generation zone located between 2,500 m and 3,000 m and gas generation zone from 3,500 m to 4,000 m approximately. Hydrocarbon accumulation could be expected in the trap formed in the period earlier than 10 Ma. as the hydrocarbon started to be expelled at 10 Ma. according to the modeling. Approximately 13,000 Line-km of multichannel seismic data integrated with 14 wells and gravity and magnetic data were analyzed to investigate the structural and stratigraphic evolution of southern part of offshore Korea. The northeast-southwest trending Taiwan-Sinzi Uplift Belt separates the area into two regions with different tectonic features, northwestern and southwestern regions. The potential hydrocarbon traps associated with anticline, tilted fault block, fault, unconformity, and rollover structure exist.

    This report consists of 2 subjects. 1) Petroleum resources assessment of the Kunsan Basin : Kunsan Basin is mainly filled with Cretaceous and Tertiary clastic sediments, and divided into Southwest Sub-basin, Central Sub-basin and Northeast Sub-basin by uplifts and faults developed in the basin. Microfossils were studied for the biostratigraphic works of drill wells in the Kunsan Basin. The microfossils include organic-walled microfossils such as spores, pollen and nonmarine dinoflagellates and calcareous microfossils such as ostracods, charophytes and gastropods. The fossil assemblages of the Kunsan Basin reveal nonmarine environments ranging from alluvial fan to shallow lacustrine and climatic variation between subtropical and cool temperate temperature in the arid/humid alternating conditions. According to the paleontological data, the Kunsan Basin was initiated in the Early Cretaceous and expanded during Paleogene followed by regional erosion at the closing time of Paleogene on which Neogene sediments have been accumulated. The Paleogene strata show laterally irregular thickness in each Epoch due to migrating depocenter. 2) Petroliferous basin analysis in Hapcheon area (I) : The Cretaceous Gyeongsang Supergroup consists of more than 9 Km sequences of sedimentary and volcanic rocks in Hapcheon-Changyong-Euiryong-Haman area and occupies the middle part of the Milyang subbasin. The Supergroup can be divided into three group; Sindong, Hayang and Yuchon groups in ascending order. Based on rock color, the Sindong Group can be subdivided into Nakdong, Hasandong and Jinju Formations. The Hayang Group can be subdivided into Chilgok, Silla Conglomerate, Haman and Jindong Formations. The Chilgok Formation includes basaltic lava and tuffs in the upper part. The Haman Formation has Kusandong tuff (keybed) in the uppermost part in the Changyong area, whereas the tuff is intercalated below the vocaniclastics in the Haman area.

    France, Todd

    Generating greater student interest in science, technology, engineering, and mathematics (STEM) has been a major topic of discussion among educators, policymakers, and researchers in recent years, as increasing the number of graduates in these fields is widely considered a necessary step for sustaining the progress of today's society. Fostering this interest must occur before students reach college, and substantial efforts have been made to engage students at K-12 levels in STEM-focused learning. Attempts to involve students in engineering, a vital and growing profession, yet one in which students often have little experience, have frequently emphasized the design and construction of physical products, a practice supported by project-based learning. This thesis examines the environment of an engineering high school course that employed the project-based model. The course is part of a dedicated curricular program which aims to provide students with positive experiences in engineering-related activities while also preparing them for the rigors of college. A case study was conducted to provide insight into the benefits and drawbacks of the learning model. The study's outcomes are intended to provide guidance to educators participating in the design and/or facilitation of project-based activities, particularly those involved with engineering education. The research was performed using a qualitative approach. Long-term engagement with course participants was deemed critical to gaining a comprehensive understanding of the interactions and events that transpired on a daily basis. Nine educators involved with the program were interviewed, as were nineteen of the course's thirty-nine students. A wealth of other relevant data -- including surveys, field notes, and evaluations of student work -- was compiled for analysis as well. The study findings suggest that experiences in problem solving and teamwork were the central benefits of the course. Limitations existed due to a

    Full Text Available Support looseness fault is a type of common fault in aeroengine. Serious looseness fault would emerge under larger unbalanced force, which would cause excessive vibration and even lead to rubbing fault, so it is important to analyze and recognize looseness fault effectively. In this paper, based on certain type turbofan engine structural features, a rotor-support-casing whole model for certain type turbofan aeroengine is established. The rotor and casing systems are modeled by means of the finite element beam method; the support systems are modeled by lumped-mass model; the support looseness fault model is also introduced. The coupled system response is obtained by numerical integral method. In this paper, based on the casing acceleration signals, the impact characteristics of symmetrical stiffness and asymmetric stiffness models are analyzed, finding that the looseness fault would lead to the longitudinal asymmetrical characteristics of acceleration time domain wave and the multiple frequency characteristics, which is consistent with the real trial running vibration signals. Asymmetric stiffness looseness model is verified to be fit for aeroengine looseness fault model.

    Full Text Available In this study, the education method which is different from traditional Chinese education methods for its accentuation of practical training is proposed. Compared with traditional engineering education methods, engineering-oriented practical training methodology is student-centered, contains various educational activities, requires interdisciplinary skills, values teamwork and have more objective evaluation methods. Based on the educational case of anti-skid control of railway train, a semi-physical simulation platform is introduced with details in design philosophy, system structure, operator interface and training process. The intention of creating the platform is to provide the students who use it with more hands-on experience since one of the key factors in transfer of learning is the diversion of practice. Based on the knowledge transfer theory, we encourage our students to do their work more independently and freely and the corresponding scores of their performance prove that the students who are better-rounded tend to perform well in the training courses we offered while those only with straight a scores may not outperform their classmates. Thus, the results indicate that this mode is effective in education and instructive to the reform of technological college education.

These issues will then be considered in more detail by referring to various approaches to the relationship between TA and technology development and by presenting a specific case study of an accompanying TA process over various development stages of the bioliq® process for converting dry biomass into fuel (Biomass to Liquid and chemicals. The accompanying TA work on the bioliq® process can, as a result of more than ten years of experience, be considered a successful technology assessment as it has opened up a new research field with a highly precautionary aspect on the one hand, and helped to win over technology‐oriented research institutes to reorienting their research work, on the other. The results of the TA studies allowed to assess e.g. the competitiveness of the bioliq® process at a very early stage. The mutual trust built up in the course of the historical development between the parties involved has always been essential for this ongoing accompanying TA process. TA has been proven, in this way, a useful tool to uncover new chances for engineering research and development, and to accompany the research process.

    High-sensitivity monitoring solutions are crucial for early warning systems of earth structures. In this paper, we discuss the design and implementation of such systems for natural and engineered slopes using two case studies. At the Gradenbach Observatory, one key element of the monitoring system is a large fiber optic strain rosette embedded in the slope. We demonstrate that the strain rosette can depict landslide deformations much earlier than geodetic sensors like GPS or total stations and is therefore well suitable for an early warning system. In a second application we report the construction of a reinforced earth structure using geogrids. A distributed fiber optic measurement system was installed to measure the current operating grade of the geogrids within the earth structure. About 2 km of Brillouin sensing cables were installed in the project area. It is demonstrated that the developed monitoring system is well suited for assessing the current state of health of reinforced earth structures.

    2016-01-01

    Full Text Available We first show that monomial ratio equations are not only very common in Physics and Engineering, but the natural type of equations in many practical problems. More precisely, in the case of models involving scale variables if the used formulas are not of this type they are not physically valid. The consequence is that when estimating the model parameters we are faced with systems of monomial ratio equations that are nonlinear and difficult to solve. In this paper, we provide an original algorithm to obtain the unique solutions of systems of equations made of linear combinations of monomial ratios whose coefficient matrix has a proper null space with low dimension that permits solving the problem in a simple way. Finally, we illustrate the proposed methods by their application to two practical problems from the hydraulic and structural fields.

    Design and analysis of Environmental Control and Life Support Systems (ECLSS) and Active Thermal Control Systems (ATCS) for spacecraft missions requires powerful software that is flexible and responsive to the demands of particular projects. CASE/A is an interactive trade study and analysis tool designed to increase productivity during all phases of systems engineering. The graphics-based command-driven package provides a user-friendly environment in which the engineer can analyze the performance and interface characteristics of an ECLS/ATC system. The package is useful during all phases of a spacecraft design program, from initial conceptual design trade studies to the actual flight, including pre-flight prediction and in-flight anomaly analysis. The CASE/A program consists of three fundamental parts: 1) the schematic management system, 2) the database management system, and 3) the simulation control and execution system. The schematic management system allows the user to graphically construct a system model by arranging icons representing system components and connecting the components with physical fluid streams. Version 4.1 contains 51 fully coded and documented default component routines. New components can be added by the user through the "blackbox" component option. The database management system supports the storage and manipulation of component data, output data, and solution control data through interactive edit screens. The simulation control and execution system initiates and controls the iterative solution process, displaying time status and any necessary diagnostic messages. In addition to these primary functions, the program provides three other important functional areas: 1) model output management, 2) system utility commands, and 3) user operations logic capacity. The model output management system provides tabular and graphical output capability. Complete fluid constituent mass fraction and properties data (mass flow, pressure, temperature

    The present century started with the creation of national petroleum companies, and it ends with those national petroleum companies exerting various types of efforts to increase the efficiency of their management. Especially, the efforts of these national petroleum companies are ever intensifying to adapt to new trends in the world petroleum market such as intensified competition, ever-deepening price unstableness, separation of structure between upstream and downstream portions, rapid development of petroleum development technologies, change of political systems and the demise of national borders, ever-increasing consciousness of environmental preservation, etc. Korea cannot be exempt from management rationalization efforts of national petroleum companies. Especially, Korea established its own national petroleum company in order to actively deal with these as its supply system is very weak. Therefore, the national petroleum company should create as many successful petroleum development businesses by actively carrying out petroleum development businesses domestically and overseas in order to establish a stable supply system of petroleum and to support the petroleum development businesses of civilian enterprises more effectively. The national petroleum company must, first of all, replace the bureaucracy with entrepreneurship. Esp., in order to enhance the efficiency of management, short- term outcome should not be emphasized over long-term tenure of petroleum development businesses, and excessive interference of government on the national petroleum company should be excluded. The entrepreneurship of the national petroleum company should be pursued in Positive-sum way, and its public image should be actively promoted through this. 35 refs., 11 figs., 32 tabs.

    different from that of gas displacement processes. The work is of experimental nature and clarifies several misconceptions in the literature. Based on experimental results, it is established that the main reason for high efficiency of solution gas drive from heavy oil reservoirs is due to low gas mobility. Chapter III presents the concept of the alteration of porous media wettability from liquid-wetting to intermediate gas-wetting. The idea is novel and has not been introduced in the petroleum literature before. There are significant implications from such as proposal. The most direct application of intermediate gas wetting is wettability alteration around the wellbore. Such an alteration can significantly improve well deliverability in gas condensate reservoirs where gas well deliverability decreases below dewpoint pressure. Part I of Chapter III studies the effect of gravity, viscous forces, interfacial tension, and wettability on the critical condensate saturation and relative permeability of gas condensate systems. A simple phenomenological network model is used for this study, The theoretical results reveal that wettability significantly affects both the critical gas saturation and gas relative permeability. Gas relative permeability may increase ten times as contact angle is altered from 0{sup o} (strongly liquid wet) to 85{sup o} (intermediate gas-wetting). The results from the theoretical study motivated the experimental investigation described in Part II. In Part II we demonstrate that the wettability of porous media can be altered from liquid-wetting to gas-wetting. This part describes our attempt to find appropriate chemicals for wettability alteration of various substrates including rock matrix. Chapter IV provides a comprehensive treatment of molecular, pressure, and thermal diffusion and convection in porous media Basic theoretical analysis is presented using irreversible thermodynamics.

  17. Creating a strategic plan for configuration management using computer aided software engineering (CASE) tools

    Smith, P.R.; Sarfaty, R.

    1993-05-01

    This paper provides guidance in the definition, documentation, measurement, enhancement of processes, and validation of a strategic plan for configuration management (CM). The approach and methodology used in establishing a strategic plan is the same for any enterprise, including the Department of Energy (DOE), commercial nuclear plants, the Department of Defense (DOD), or large industrial complexes. The principles and techniques presented are used world wide by some of the largest corporations. The authors used industry knowledge and the areas of their current employment to illustrate and provide examples. Developing a strategic configuration and information management plan for DOE Idaho Field Office (DOE-ID) facilities is discussed in this paper. A good knowledge of CM principles is the key to successful strategic planning. This paper will describe and define CM elements, and discuss how CM integrates the facility`s physical configuration, design basis, and documentation. The strategic plan does not need the support of a computer aided software engineering (CASE) tool. However, the use of the CASE tool provides a methodology for consistency in approach, graphics, and database capability combined to form an encyclopedia and a method of presentation that is easily understood and aids the process of reengineering. CASE tools have much more capability than those stated above. Some examples are supporting a joint application development group (JAD) to prepare a software functional specification document and, if necessary, provide the capability to automatically generate software application code. This paper briefly discusses characteristics and capabilities of two CASE tools that use different methodologies to generate similar deliverables.

    This case study analyzes the application of the cleanroom software development methodology to the development of production software at the NASA/Goddard Space Flight Center. The cleanroom methodology emphasizes human discipline in program verification to produce reliable software products that are right the first time. Preliminary analysis of the cleanroom case study shows that the method can be applied successfully in the FDD environment and may increase staff productivity and product quality. Compared to typical Software Engineering Laboratory (SEL) activities, there is evidence of lower failure rates, a more complete and consistent set of inline code documentation, a different distribution of phase effort activity, and a different growth profile in terms of lines of code developed. The major goals of the study were to: (1) assess the process used in the SEL cleanroom model with respect to team structure, team activities, and effort distribution; (2) analyze the products of the SEL cleanroom model and determine the impact on measures of interest, including reliability, productivity, overall life-cycle cost, and software quality; and (3) analyze the residual products in the application of the SEL cleanroom model, such as fault distribution, error characteristics, system growth, and computer usage.

    Full Text Available The attitude of students towards the integration of the internet as a study tool and communication channel in teaching and learning in engineering has been investigated. A study was carried out in the Faculty of Engineering, Ahmadu Bello University Zaria, Nigeria, aimed at investigating the effect of certain variables such as gender, course of study, computer experience, and the percentage of internet usage on teaching and learning processes. A well-structured questionnaire was administered to a randomly selected five hundred (500 male and female students across the seven (7 departments of the faculty and about 85% were filled and returned. The study also examines the university management's perspectives and strategies to incorporate internet usage in teaching and learning processes especially in engineering. Amazingly, responses received showed that experience in the use of the computer in surfing the internet for problem based activities mainly affects the level of internet usage across the faculty. This factor makes some students to misplace their priority in internet usage emphasizing on e-mail correspondence and social networking rather than sourcing for information and solving problems as it is done by a few students. Furthermore, findings support that internet cannot entirely substitute for traditional teaching and learning processes like text reading but can serve as a reasonable alternative when the latter is unavailable

  6. Modeling and forecasting petroleum futures volatility

    Sadorsky, Perry [York Univ., Schulich School of Business, Toronto, ON (Canada)

    2006-07-15

    Forecasts of oil price volatility are important inputs into macroeconometric models, financial market risk assessment calculations like value at risk, and option pricing formulas for futures contracts. This paper uses several different univariate and multivariate statistical models to estimate forecasts of daily volatility in petroleum futures price returns. The out-of-sample forecasts are evaluated using forecast accuracy tests and market timing tests. The TGARCH model fits well for heating oil and natural gas volatility and the GARCH model fits well for crude oil and unleaded gasoline volatility. Simple moving average models seem to fit well in some cases provided the correct order is chosen. Despite the increased complexity, models like state space, vector autoregression and bivariate GARCH do not perform as well as the single equation GARCH model. Most models out perform a random walk and there is evidence of market timing. Parametric and non-parametric value at risk measures are calculated and compared. Non-parametric models outperform the parametric models in terms of number of exceedences in backtests. These results are useful for anyone needing forecasts of petroleum futures volatility. (author)

    This article considers security assurance for power engineering machinery in the design and production phases. The Federal Law "On Technical Regulation" and the Customs Union Technical Regulations "On Safety of Machinery and Equipment" are analyzed in the legal, technical, and economic aspect with regard to power engineering machine industry products. From the legal standpoint, it is noted that the practical enforcement of most norms of the Law "On Technical Regulation" makes it necessary to adopt subordinate statutory instruments currently unavailable; moreover, the current level of adoption of technical regulations leaves much to be desired. The intensive integration processes observed in the Eurasian Region in recent years have made it a more pressing task to harmonize the laws of the region's countries, including their technical regulation framework. The technical aspect of analyzing the technical regulation of the Customs Union has been appraised by the IDEF0 functional modeling method. The object of research is a steam turbine plant produced at the turbine works. When developing the described model, we considered the elaboration of safety case (SC) requirements from the standpoint of the chief designer of the turbine works as the person generally responsible for the elaboration of the SC document. The economic context relies on risk analysis and appraisal methods. In their respect, these are determined by the purposes and objectives of analysis, complexity of considered objects, availability of required data, and expertise of specialists hired to conduct the analysis. The article proposes the description of all sources of hazard and scenarios of their actualization in all production phases of machinery life cycle for safety assurance purposes. The detection of risks and hazards allows forming the list of unwanted events. It describes the sources of hazard, various risk factors, conditions for their rise and development, tentative risk appraisals, and

    The use of laboratory animals in tissue engineering research is an important underexposed ethical issue. Several ethical questions may be raised about this use of animals. This article focuses on the possibilities of reducing the number of animals used. Given that there is considerable debate about the adequacy of the current animal models in tissue engineering research, we investigate whether it is possible to reduce the number of laboratory animals by selecting and using only those models that have greatest predictive value for future clinical application of the tissue engineered product. The field of articular cartilage tissue engineering is used as a case study. Based on a study of the scientific literature and interviews with leading experts in the field, an overview is provided of the animal models used and the advantages and disadvantages of each model, particularly in terms of extrapolation to the human situation. Starting from this overview, it is shown that, by skipping the small models and using only one large preclinical model, it is indeed possible to restrict the number of animal models, thereby reducing the number of laboratory animals used. Moreover, it is argued that the selection of animal models should become more evidence based and that researchers should seize more opportunities to choose or create characteristics in the animal models that increase their predictive value.

    Full Text Available This empirical study was conducted to determine factors that influence the career choice among engineers in a Malaysian manufacturing plant. Subjects of this study were taken from engineers in one of manufacturing plant in Malaysia. As hypothesized, the results suggest that perceptions of person-job fit and financial rewards are significant factors that influence the career choice of engineers. Contrast to our hypothesis, influence from family members does not have any impact in determining the career choice among engineers. Interventions in attracting more engineers to remain in their career path and limitations of the study are also being discussed in the paper.

    Six North Slope petroleum systems are identified, described, and mapped using oil-to-oil and oil-to-source rock correlations, pods of active source rock, and overburden rock packages. To map these systems, we assumed that: a) petroleum source rocks contain 3.2 wt. % organic carbon (TOC); b) immature oil-prone source rocks have hydrogen indices (HI) >300 (mg HC/gm TOC); c) the top and bottom of the petroleum (oil plus gas) window occur at vitrinite reflectance values of 0.6 and 1.0% Ro, respectively; and d) most hydrocarbons are expelled within the petroleum window. The six petroleum systems we have identified and mapped are: a) a southern system involving the Kuna-Lisburne source rock unit that was active during the Late Jurassic and Early Cretaceous; b) two western systems involving source rock in the Kingak-Blankenship, and GRZ-lower Torok source rock units that were active during the Albian; and c) three eastern systems involving the Shublik-Otuk, Hue Shale and Canning source rock units that were active during the Cenozoic. The GRZ-lower Torok in the west is correlative with the Hue Shale to the east. Four overburden rock packages controlled the time of expulsion and gross geometry of migration paths: a) a southern package of Early Cretaceous and older rocks structurally-thickened by early Brooks Range thrusting; b) a western package of Early Cretaceous rocks that filled the western part of the foreland basin; c) an eastern package of Late Cretaceous and Paleogene rocks that filled the eastern part of the foreland basin; and d) an offshore deltaic package of Neogene rocks deposited by the Colville, Canning, and Mackenzie rivers. This petroleum system poster is part of a series of Northern Alaska posters on modeling. The poster in this session by Saltus and Bird present gridded maps for the greater Northern Alaskan onshore and offshore that are used in the 3D modeling poster by Lampe and others.

    This paper examines the mission, structure and outputs of one organisation, the Student Platform for Engineering Education Development (SPEED), as a case study for how student-led organisations can use student involvement to promote and sustain student self-efficacy in an academic field. SPEED attracts young people to engineering through student participation in engineering education (EE). SPEED is a global, non-profit student organisation that functions as an interdisciplinary network to diversify dialogue, stimulate change and impact the development of EE and its effect on society. SPEED is directly attracting young people to engineering in various ways: the organisation of its keynote event, the Global Student Forum; facilitating interactions between globally minded, socially inclined engineers with aspirations to change the world; and through the global dissemination of SPEED\\'s work and practices through broad and relevant channels. Short-term outcomes are highlighted here. This case study can serve as a model for student engagement and involvement in other disciplines. © 2010 SEFI.

  20. A Case of Engineering Quality for Mobile Healthcare Applications Using Augmented Personal Software Process Improvement

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Mobile healthcare systems are currently considered as key research areas in the domain of software engineering. The adoption of modern technologies, for mobile healthcare systems, is a quick option for industry professionals. Software architecture is a key feature that contributes towards a software product, solution, or services. Software architecture helps in better communication, documentation of design decisions, risks identification, basis for reusability, scalability, scheduling, and reduced maintenance cost and lastly it helps to avoid software failures. Hence, in order to solve the abovementioned issues in mobile healthcare, the software architecture is integrated with personal software process. Personal software process has been applied successfully but it is unable to address the issues related to architectural design and evaluation capabilities. Hence, a new technique architecture augmented personal process is presented in order to enhance the quality of the mobile healthcare systems through the use of architectural design with integration of personal software process. The proposed process was validated by case studies. It was found that the proposed process helped in reducing the overall costs and effort. Moreover, an improved architectural design helped in development of high quality mobile healthcare system.

    ENGLISH ABSTRACT: Value engineering (VE has been effectively applied in many different areas. The results have been very encouraging, and many companies accept VE not only as a tool to reduce costs, but also to improve the quality of their produce and streamline their systems. This paper attempts to highlight the application of VE in agriculture, as in pistachio tree farms in Iran. It is found that by implementing VE, unnecessary cultivation costs are lowered. Many of the other factors that lead to the inefficient use of resources could be resolved. In this study, the province of Yazd Iran was studied. Unfortunately there are cases of mismanagement and problems in agriculture management; and the problems must be resolved to make the system of pistachio growing more efficient. The prime objective of this paper is to introduce the concept of value engineering and highlight its application in pistachio farms. The results suggest that it is essential to use Indian Neem pesticide, because it is economically feasible and environmentally friendly to pistachio trees.

    In western China.most petroliferous basins are superposed due to their multi-periodic tectonic evolution,and the mechanisms of petroleum migration and accumulation are so complex that much more sophisticated methodologies are necessary for depiction of these mechanisms and identification of petroleum occurrences.For this purpose,in this article,a new methodology was formulated which includes:(1) vertical identification of petroleum migration and accumulation fluid dynamic systems in the superposed basins;(2) analysis of the effect of large scale regional faults and fault combinations on the fluids exchange between the vertically identified different systems;(3) analysis of petroleum migration and accumulation in each vertically identified system,and establishment of appropriate geological model of petroleum migration and accumulation for each vertically identified system.Using this methodology,the satisfactory results obtained in the Lunnan Uplift of Tarim Basin and Ludong Uplift of Jungar Basin case studies are:(1) existence of different vertical fluid dynamic systems in western China's superposed basins which are very necessary for understanding the mechanism of petroleum migration and accumulation;(2) in deep system,long-distance lateral petroleum migration and accumulation mainly take place along the long time exposed unconformity with weathered,fractured or karst reservoir rocks;(3) regional faults are the main conducts for fluids migration from deep system up to middle and/or upper systems.As to middle and/or upper systems,regional faults play a role of "petroleum source".Small faults within middle and/or upper systems conduct petroleum to carrier beds with less impeding force;(4) petroleum migrated from deep system vertically up to middle and/or upper systems will migrate laterally in carrier beds of these systems and accumulate to form pools near or far from faults.

    Full Text Available A capstone project in current engineering education is often introduced to enable the holistic attainment of engineering knowledge by an engineering undergraduate. Essentially project-based in nature, there exists a need to ensure that part of the attainment process involves key industry practices – such practices being necessary in attaining the status of a professional engineer. Herein lies the synergy that can be made use of between industry and academia. By exposing engineering undergraduates to a project which addresses an engineering challenge and providing them with the opportunity to learn from professional engineers who are experts in the fields of safety, sustainability, quality management, ethics and project management, this culminates in the implementation of a prototype design which incorporates the amalgamation of knowledge from industry and academia. This paper presents the unique curriculum developed in a capstone project module, incorporating learning sessions from professional engineers in the five (5 key areas of industry practice highlighted above and how these have contributed to significantly enhancing the learning outcome and hence programme outcome attainment of the engineering undergraduates who have experienced the module.

  6. Framework for Small-Scale Experiments in Software Engineering: Guidance and Control Software Project: Software Engineering Case Study

    1998-01-01

    Software is becoming increasingly significant in today's critical avionics systems. To achieve safe, reliable software, government regulatory agencies such as the Federal Aviation Administration (FAA) and the Department of Defense mandate the use of certain software development methods. However, little scientific evidence exists to show a correlation between software development methods and product quality. Given this lack of evidence, a series of experiments has been conducted to understand why and how software fails. The Guidance and Control Software (GCS) project is the latest in this series. The GCS project is a case study of the Requirements and Technical Concepts for Aviation RTCA/DO-178B guidelines, Software Considerations in Airborne Systems and Equipment Certification. All civil transport airframe and equipment vendors are expected to comply with these guidelines in building systems to be certified by the FAA for use in commercial aircraft. For the case study, two implementations of a guidance and control application were developed to comply with the DO-178B guidelines for Level A (critical) software. The development included the requirements, design, coding, verification, configuration management, and quality assurance processes. This paper discusses the details of the GCS project and presents the results of the case study.

  19. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    Science.gov (United States)

    Lindberg, Robert E.; Pinelli, Thomas E.; Batterson, James G.

    2008-01-01

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

    In 2004, NASA faced major knowledge sharing challenges due to geographically isolated field centers that inhibited personnel from sharing experiences and ideas. Mission failures and new directions for the agency demanded better collaborative tools. In addition, with the push to send astronauts back to the moon and to Mars, NASA recognized that systems engineering would have to improve across the agency. Of the ten field centers, seven had not built a spacecraft in over 30 years, and had lost systems engineering expertise. The Systems Engineering Community of Practice came together to capture the knowledge of its members using the suite of collaborative tools provided by the NASA Engineering Network (NEN.) The NEN provided a secure collaboration space for over 60 practitioners across the agency to assemble and review a NASA systems engineering handbook. Once the handbook was complete, they used the open community area to disseminate it. This case study explores both the technology and the social networking that made the community possible, describes technological approaches that facilitated rapid setup and low maintenance, provides best practices that other organizations could adopt, and discusses the vision for how this community will continue to collaborate across the field centers to benefit the agency as it continues exploring the solar system.

    The focus on biodiesel research has shown a tremendous growth over the last few years. Several microbial and plant sources are being explored for the sustainable biodiesel production to replace the petroleum diesel. Conventional methods of biodiesel production have several limitations related to yield and quality, which led to development of new engineering strategies to improve the biodiesel production in plants, and microorganisms. Substantial progress in utilizing algae, yeast, and Escherichia coli for the renewable production of biodiesel feedstock via genetic engineering of fatty acid metabolic pathways has been reported in the past few years. However, in most of the cases, the successful commercialization of such engineering strategies for sustainable biodiesel production is yet to be seen. This paper systematically presents the drawbacks in the conventional methods for biodiesel production and an exhaustive review on the present status of research in genetic engineering strategies for production of biodiesel in plants, and microorganisms. Further, we summarize the technical challenges need to be tackled to make genetic engineering technology economically sustainable. Finally, the need and prospects of genetic engineering technology for the sustainable biodiesel production and the recommendations for the future research are discussed.

    The triangle model, as an intuitive platform for illustrating sustainability status and trends in economic development, seems to hold promise as an analytical management tool liable to be used by researchers and policy-makers at different levels due to its simplicity and flexibility. Based on the interrelationships among economic development, resource-energy consumption and environmental pollution, in conjunction with ecological performance and the triangle method, a definition for economic system sustainability (ESS) was proposed, and a novel triangle method was designed to evaluate economic system sustainability. This article selected Daqing city, an important industrial base of petroleum chemical industry in China, as a research region.As a case study, the triangle method was applied to assess the economic system sustainability of Daqing city. Daqing city is located in the western of Heilongjiang province, and covers a total area of 2.1219 million hm~2 with four counties and five districts under its administration. It had a total population of 2.693 million in 2006. The results show that the economic system sustainability of Daqing during 1991 - 2006 had a poor performance. The ESS of Daqing between 1991 and 1995 reveals a common sustainable trend, while that from 1996 to 2000 demonstrates a relatively strong sustainable trend, and has a common sustainable trend during 2001 - 2006.%三角模型作为一种直观的平台能够很好地图解区域可持续综合发展状况及长期趋势.由于具有直观性和简明性,三角模型易于被不同层次的学者和政策制定者理解和应用.根据经济发展、资源-能源消耗及环境污染的相互关系,结合生态学表现,利用三角模型工具分析评估区域经济可持续发展状况和长期趋势.本文选择我国最大的石油资源型城市--大庆市作为典型案例.大庆市位于黑龙江省西部,下辖5个区和4个县,2006年全市土地总面积为2.1219万hm~2,总人口269

    Pacella, Massimo; Grieco, Antonio; Blaco, Marzia

    2016-01-01

    In modern industry, the development of complex products involves engineering changes that frequently require redesigning or altering the products or their components. In an engineering change process, engineering change requests (ECRs) are documents (forms) with parts written in natural language describing a suggested enhancement or a problem with a product or a component. ECRs initiate the change process and promote discussions within an organization to help to determine the impact of a change and the best possible solution. Although ECRs can contain important details, that is, recurring problems or examples of good practice repeated across a number of projects, they are often stored but not consulted, missing important opportunities to learn from previous projects. This paper explores the use of Self-Organizing Map (SOM) to the problem of unsupervised clustering of ECR texts. A case study is presented in which ECRs collected during the engineering change process of a railways industry are analyzed. The results show that SOM text clustering has a good potential to improve overall knowledge reuse and exploitation.

    Full Text Available The paper presents studies on oil removal from soil by means of water elution with a help of shaking out the contaminants from the soil. The tests were performed on simulated soil samples contaminated with a mixture of petroleum hydrocarbons. The study consisted in recording the time influence and the number of elution cycles to remove contaminants from the soil. The samples were then subject to the determination of petroleum hydrocarbons, aliphatic hydrocarbons, and BTEX compounds (benzene, toluene, ethylbenzene, xylene. Due to adding various concentrations of petroleum into particular soil samples and applying different shaking times, it was possible to find out the impact of petroleum content and sample shaking duration on the course and possibility of petroleum substances removal by means of elution process.

    2016-07-01

    Full Text Available Nigeria ranks high among the community of oil producers both in the world. It is, therefore, paradoxical that Nigeria, with such profile in Organization of Petroleum Exporting Countries (OPEC statistics finds it difficult to optimize its supply distribution while spending so much money on transportation and distribution. This paper thus reviews the petroleum product supply and distribution systems in the country. Thus, we develop a single period, single product deterministic mathematical model to effectively distribute the product to the end user through the most effective channel to the interest of the economy of the country. In our model, we first consider a perfect condition in the petroleum industry irrespective of the production crises and conflicts like pipeline vandalism, communal instability. We then consider different scnearios that presumes several breakdown cases in pipeline connection to anaylze the survivability of the network of petroleum distribution.

  13. Detecting and (not) dealing with plagiarism in an engineering paper: beyond CrossCheck-a case study.

    Science.gov (United States)

    Zhang, Xin-xin; Huo, Zhao-lin; Zhang, Yue-hong

    2014-06-01

    In papers in areas such as engineering and the physical sciences, figures, tables and formulae are the basic elements to communicate the authors' core ideas, workings and results. As a computational text-matching tool, CrossCheck cannot work on these non-textual elements to detect plagiarism. Consequently, when comparing engineering or physical sciences papers, CrossCheck may return a low similarity index even when plagiarism has in fact taken place. A case of demonstrated plagiarism involving engineering papers with a low similarity index is discussed, and editor's experiences and suggestions are given on how to tackle this problem. The case shows a lack of understanding of plagiarism by some authors or editors, and illustrates the difficulty of getting some editors and publishers to take appropriate action. Consequently, authors, journal editors, and reviewers, as well as research institutions all are duty-bound not only to recognize the differences between ethical and unethical behavior in order to protect a healthy research environment, and also to maintain consistent ethical publishing standards.

    Science.gov (United States)

    Balakrishnan, Balamuralithara; Er, Pek Hoon; Visvanathan, Punita

    2013-09-01

    The unique properties of nanotechnology have made nanotechnology education and its related subjects increasingly important not only for students but for mankind at large. This particular technology brings educators to work together to prepare and produce competent engineers and scientists for this field. One of the key challenges in nanotechnology engineering is to produce graduate students who are not only competent in technical knowledge but possess the necessary attitude and awareness toward the social and ethical issues related to nanotechnology. In this paper, a research model has been developed to assess Malaysian nanotechnology engineering students' attitudes and whether their perspectives have attained the necessary objectives of ethical education throughout their programme of study. The findings from this investigation show that socio ethical education has a strong influence on the students' knowledge, skills and attitudes pertaining to socio ethical issues related to nanotechnology.

    2015-01-01

    The unusual GRB 110709B triggered Swift/BAT twice, with a time difference of $\\sim 11$ minutes. Its light curve presented three noticeable peaks but only two were originally identified. In this work, we describe each peak as due to a different central-engine phase: the first one is the millisecond-protomagnetar stage, the second one is the BH-formation collapse phase and the last one is the Collapsar scenario with a Blandford-Znajek engine. Additionally, we analyze and explain the afterglow phase evoking the standard fireball model. Our model can successfully describe the timescales, fluxes and spectral indices observed for GRB 110709B.

  17. A BLUEPRINT FOR RESEARCH-LED TEACHING ENGINEERING AT SCHOOLS: A CASE STUDY FOR TAYLOR’S UNIVERSITY

    Directory of Open Access Journals (Sweden)

    MUSHTAK AL-ATABI

    2013-04-01

    Full Text Available Although it is expected that research conducted at universities and institutions of higher learning will have some positive impact on the teaching quality, the literature seem to point in another direction. Available literature reports zero correlation between teaching and research. However, this need not be the case and a number of recommendations to create a positive correlation between teaching and research are proposed. This paper outlines a framework that utilises the Grand Challenges for Engineering and CDIO to create a clear link between teaching and research in Taylor’s School of Engineering. Aligning the academic staff research objectives to the Grand Challenges, creates a sense of purpose that extends beyond the academic staff to their students. Ensuring that students’ projects and other CDIO activities are derived from the academic staff research interests help creates a learning environment in which research and teaching are integrated. This integration is highly desirable as it benefits both the students and the academic staff.

  2. Development of a General Package for Resolution of Uncertainty-Related Issues in Reservoir Engineering

    Directory of Open Access Journals (Sweden)

    Liang Xue

    2017-02-01

    Full Text Available Reservoir simulations always involve a large number of parameters to characterize the properties of formation and fluid, many of which are subject to uncertainties owing to spatial heterogeneity and insufficient measurements. To provide solutions to uncertainty-related issues in reservoir simulations, a general package called GenPack has been developed. GenPack includes three main functions required for full stochastic analysis in petroleum engineering, generation of random parameter fields, predictive uncertainty quantifications and automatic history matching. GenPack, which was developed in a modularized manner, is a non-intrusive package which can be integrated with any existing commercial simulator in petroleum engineering to facilitate its application. Computational efficiency can be improved both theoretically by introducing a surrogate model-based probabilistic collocation method, and technically by using parallel computing. A series of synthetic cases are designed to demonstrate the capability of GenPack. The test results show that the random parameter field can be flexibly generated in a customized manner for petroleum engineering applications. The predictive uncertainty can be reasonably quantified and the computational efficiency is significantly improved. The ensemble Kalman filter (EnKF-based automatic history matching method can improve predictive accuracy and reduce the corresponding predictive uncertainty by accounting for observations.

The purpose of this study was to describe the existing knowledge transfer practices in selected aerospace companies as perceived by highly experienced engineers retiring from the company. Specifically it was designed to investigate and describe (a) the processes and procedures used to transfer knowledge, (b) the systems that encourage knowledge transfer, (c) the impact of management actions on knowledge transfer, and (d) constraining factors that might impede knowledge transfer. Methodology. A descriptive case study was the methodology applied in this study. Qualitative data were gathered from highly experienced engineers from 3 large aerospace companies in Southern California. A semistructured interview was conducted face-to-face with each participant in a private or semiprivate, non-workplace setting to obtain each engineer's perspectives on his or her company's current knowledge transfer practices. Findings. The participants in this study preferred to transfer knowledge using face-to-face methods, one-on-one, through actual troubleshooting and problem-solving scenarios. Managers in these aerospace companies were observed as having knowledge transfer as a low priority; they tend not to promote knowledge transfer among their employees. While mentoring is the most common knowledge transfer system these companies offer, it is not the preferred method of knowledge transfer among the highly experienced engineers. Job security and schedule pressures are the top constraints that impede knowledge transfer between the highly experienced engineers and their coworkers. Conclusions. The study data support the conclusion that the highly experienced engineers in the study's aerospace companies would more likely transfer their knowledge to those remaining in the industry if the transfer could occur face-to-face with management support and acknowledgement of their expertise and if their job security is not threatened. The study also supports the conclusion that managers

  7. Case study: Comparison of motivation for achieving higher performance between self-directed and manager-directed aerospace engineering teams

    Erlick, Katherine

    "The stereotype of engineers is that they are not people oriented; the stereotype implies that engineers would not work well in teams---that their task emphasis is a solo venture and does not encourage social aspects of collaboration" (Miner & Beyerlein, 1999, p. 16). The problem is determining the best method of providing a motivating environment where design engineers may contribute within a team in order to achieve higher performance in the organization. Theoretically, self-directed work teams perform at higher levels. But, allowing a design engineer to contribute to the team while still maintaining his or her anonymity is the key to success. Therefore, a motivating environment must be established to encourage greater self-actualization in design engineers. The purpose of this study is to determine the favorable motivational environment for design engineers and describe the comparison between two aerospace design-engineering teams: one self-directed and the other manager directed. Following the comparison, this study identified whether self-direction or manager-direction provides the favorable motivational environment for operating as a team in pursuit of achieving higher performance. The methodology used in this research was the case study focusing on the team's levels of job satisfaction and potential for higher performance. The collection of data came from three sources, (a) surveys, (b) researcher observer journal and (c) collection of artifacts. The surveys provided information regarding personal behavior characteristics, potentiality for higher performance and motivational attributes. The researcher journal provided information regarding team dynamics, individual interaction, conflict and conflict resolution. The milestone for performance was based on the collection of artifacts from the two teams. The findings from this study illustrated that whether the team was manager-directed or self-directed does not appear to influence the needs and wants of the

    Full Text Available Petroleum based hydrocarbon degrading and biosurfactant producing bacterial strain was isolated from an automobile engine. The strain was identified as Bacillus cereus DRDU1 on the basis of 16S rDNA sequencing analysis. The strain was found to be efficiently degrading 96% of kerosene making it a potential tool for bioremediation of petroleum based contaminants. Production and optimization of the biosurfactant produced by the isolate were also carried out. Surface hydrophobicity trait of isolate was found to be 60.67 ± 1.53% and foaming percentage of the crude biosurfactant was found to be 31.33 ± 0.58%. The presence of amino acids and sugar moieties in the biosurfactant was confirmed by biochemical tests and were further validated by FTIR (the Fourier transform infrared spectrometric analysis revealing the presence of υOH, υCOO, υCOOH, υCH (stretching, υNH, υCH2, υCH3, and υCH (bending, and υCO (ester in the surfactant. The decrease in contact angle of hydrocarbon oil from (30.67 ± 1.15° to (21.3 ± 1.53° respectively after 3 and 6 days of incubation reveals its potential to emulsify petroleum oil. Further, emulsification index (E24 of biosurfactant against kerosene, crude oil, and used engine oil were determined to be 55.33 ± 1.53%, 29.67 ± 1.53%, and 20 ± 1% respectively which attracts its future application in MEOR (microbial enhanced oil recovery process.

    The failure frequency of the Emergency Diesel Generator(EDG) at Nuclear Power Plants(NPPs) is not so much lower than that of the Marine engines, whereas the running hours of the diesel engine at NPPs is much less than those of the engines for commercial service. The primary factor results from the severe surveillance test requirements such as fast start, large number of starting test, fast load-run, high load running, etc. The other factor comes from the excessive maintenance based on the engine maker's instruction manual that did not incorporate the peculiar characteristics of the diesel engines at NPPs. In this paper, the present preventive maintenance program on the basis of the Pielstick diesel engines was reviewed for the purpose of securing the reliability of the emergency diesel generator at NPPs and the ways for its improvement were presented by referring to the overseas cases for their applications.

    María Ruth Vargas Leyva

    2000-11-01

    Full Text Available This is a study of the career trajectories of engineers in the company Sanyo Video Components. Three stages in the development of the professional career are recognized: initial career stage, mid-career and late stage career. Results indicate that the career’s trajectory is internally determined by the area of career development and job hierarchy. In external mobility, there are limitations of individual and family type; those of an individual type are age and area of career development; those of a family type are civil state, spouse’s occupation and the presence and number of children. The results of other studies are confirmed in relation to the engineers’ practical training in the business, based on the initial career stage, the step from the technical dimension to the administrative, and the decrease in promotion potential which comes with age, as well as the professional conversion process of engineers who have various types of professional training.

    Full Text Available Engineering Students in India like elsewhere worldwide need well designed classrooms furniture which can enable them to attend lectures without negative impact in the long run. Engineering students from India have not yet been involved in suggesting their requirements for improving the mostly out-dated furniture at their colleges. Among the available improvement techniques, Kano Model is one of the most effective improvement approaches. The main objective of the study was to identify and categorise all the main attributes regarding the classrooms furniture for the purpose of increasing student satisfaction in the long run. Kano Model has been well applied to make an exhaustive list of requirements for redesigning classroom furniture. Cronbach Alpha was computed with the help of SPSS 16.0 for validation purpose and it ranged between 0.8 and 0.9 which is a good internal consistency. Further research can be done by integrating Kano Model with Quality Function Deployment.

    Full Text Available Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies are not integrated. Therefore, they achieve less than desired improvements in productivity, or force management to make tradeoff decisions between software quality and developer efficiency. Thus the production lines have to be developed faster, too. A very important role in this development is Software Engineering because many production processes are 'computer aided', so software has to be designed for this production system. It seems very important to do the software engineering right and fast.

  2. Applying Pareto multi-criteria decision making in concurrent engineering: A case study of polyethylene industry

    Akbar A. Tabriz

    2011-07-01

    Full Text Available Concurrent engineering (CE is one of the widest known techniques for simultaneous planning of product and process design. In concurrent engineering, design processes are often complicated with multiple conflicting criteria and discrete sets of feasible alternatives. Thus multi-criteria decision making (MCDM techniques are integrated into CE to perform concurrent design. This paper proposes a design framework governed by MCDM technique, which are in conflict in the sense of competing for common resources to achieve variously different performance objectives such as financial, functional, environmental, etc. The Pareto MCDM model is applied to polyethylene pipe concurrent design governed by four criteria to determine the best alternative design to Pareto-compromise design.

  7. THE HYDROGEN-FUELLED INTERNAL COMBUSTION ENGINES FOR MARINE APPLICATIONS WITH A CASE STUDY

    Directory of Open Access Journals (Sweden)

    Ibrahim S. Seddiek

    2015-03-01

    Full Text Available Modern marine power plants have been designed to improve the overall ship’s efficiency. This pushed the designers of marine machinery to search for unconventional fuels for these plants. During the previous years, diesel oil has been extensively used on-board ships. Due to the high price of light diesel oil and the environmental problems resulting from the use of heavy fuel oil, it has become necessary to search for an alternative to traditional fuels. As a result, natural gas fuel has been used on-board some types of ships, especially short-voyage cruise ships. Unfortunately, there are still some technical and logistic problems related to the use of natural gas as a fuel, especially as it is considered a non-renewable energy source. The use of hydrogen fuel on-board ships, particularly in modern power plants may contribute to overcoming the above problems. The present paper considers the possibility of the use of hydrogen fuel for marine applications and discusses different stages of hydrogen gas cycle beginning with hydrogen generation process from clean energy until using it as fuel for internal combustion engines on-board one RO/RO ship, named Taba, operating in the Mediterranean Sea. Compared to the diesel engine, the hydrogen fuelled engine is found to be lower in thermal efficiency and fuel consumption, however, some adjustments are needed.

  10. Local Perceptions of Corporate Social Responsibility for Arctic Petroleum in the Barents Region

    Directory of Open Access Journals (Sweden)

    Ilan Kelman

    2016-11-01

    Full Text Available Corporate social responsibility (CSR is promoted and critiqued by many players involved in or opposed to petroleum exploration and extraction, although a common understanding of CSR's theoretical and practical meanings rarely exists. This paper uses Arctic petroleum in the Barents region (Norway and Russia to investigate local perceptions of CSR. We conducted open-ended, semi-structured interviews in four locations: Hammerfest, Murmansk, Komi Republic, and Nenets Autonomous Okrug (NAO. Interviewees included the local population, regional and local authorities, non-governmental organisations (NGOs, and petroleum company representatives. The field research suggests that those who gain directly from the petroleum industry and do not directly experience negative impacts were more inclined to be positive about the industry, although overall, general support for petroleum activity was high. In some cases, positive economic benefits resulted in greater tolerance of environmental risk. Sometimes, the industry and government were criticised by locals for failing to support a more equitable distribution of broader economic benefits. Rather than splitting along for-profit/NGO or indigenous/non-indigenous lines, our analysis suggests that those who are closer to the petroleum industry or its benefits, termed ‘insiders’, tend to be more positive than ‘outsiders’. This study is perhaps the first of its kind in its focus on local perceptions of CSR for Arctic petroleum across the Barents region. The findings of this study not only match with that of the previous literature on Arctic petroleum but also provide further practical and theoretical insights by indicating subtleties and nuances within the localities examined.

  11. Biotechnology in petroleum recovery. The microbial EOR

    Sen, Ramkrishna [Department of Biotechnology, Indian Institute of Technology (IIT), Kharagpur, West Bengal 721302 (India)

    2008-12-15

    Biotechnology has played a significant role in enhancing crude oil recovery from the depleted oil reservoirs to solve stagnant petroleum production, after a three-stage recovery process employing mechanical, physical and chemical methods. Biotechnologically enhanced oil recovery processes, known as microbial enhanced oil recovery (MEOR), involve stimulating indigenous reservoir microbes or injecting specially selected consortia of natural bacteria into the reservoir to produce specific metabolic events that lead to improved oil recovery. This also involves flooding with oil recovery agents produced ex situ by industrial or pilot scale fermentation. This paper essentially reviews the operating mechanisms and the progress made in enhanced oil recovery through the use of microbes and their metabolic products. Improvement in oil recovery by injecting solvents and gases or by energizing the reservoir microflora to produce them in situ for carbonate rock dissolution and reservoir re-pressurization has been enunciated. The role of biosurfactants in oil mobilization through emulsification and that of biopolymers for selective plugging of oil-depleted zones and for biofilm formation have been delineated. The spoil sport played by sulfate-reducing bacteria (SRB) in MEOR has also been briefly reviewed. The importance of mathematical models used in predicting the applicability of an MEOR strategy and the microbial growth and transport has been qualitatively discussed. The results of some laboratory studies and worldwide field trials applying ex situ and in situ MEOR technologies were compiled and interpreted. However, the potential of the MEOR technologies has not been fully realized due to poor yield of the useful microbial metabolic products, growth inhibition by accumulated toxic metabolites and longer time of incubation. A complete evaluation and assessment of MEOR from an engineering standpoint based on economics, applicability and performance is required to further

    Science.gov (United States)

    Langton, Stewart Gordon

    Two groups of students in introductory physics courses of an Access Program for engineering technologies were the subjects of this study. Students with a wide range of academic histories and abilities were enrolled in the program; many of the students were re-entry and academically unprepared for post-secondary education. Five years of historical data were evaluated to use as a benchmark for revised instruction. Data were gathered to describe the pre-course academic state of the students and their academic progress during two physics courses. Additional information was used to search for factors that might constrain academic success and as feedback for the instructional methods. The data were interpreted to regulate constructivist design features for the physics courses. The Engineering Technology Access Program was introduced to meet the demand from non-traditional students for admission to two-year engineering' technology programs, but who did not meet normal academic requirements. The duration of the Access Program was two terms for electronic and computer engineering students and three terms for civil and mechanical engineering students. The sequence of mathematics and physics courses was different for the two groups. The Civil/Mechanical students enrolled in their first mathematics course before undertaking their first physics course. The first mathematics and physics courses for the Electronics students were concurrent. Academic success in the two groups was affected by this difference. Over a five-year period the success rate of students graduating with a technology diploma was approximately twenty-five percent. Results from this study indicate that it was possible to reduce the very high attrition in the combined Access/Technology Programs. While the success rate for the Electronics students increased to 38% the rate for the Civil/Mechanical students increased dramatically to 77%. It is likely that several factors, related to the extra term in the Access

  13. Site characterization and petroleum hydrocarbon plume mapping

    Energy Technology Data Exchange (ETDEWEB)

    Ravishankar, K. [Harding Lawson Associates, Houston, TX (United States)

    1996-12-31

    This paper presents a case study of site characterization and hydrocarbon contamination plume mapping/delineation in a gas processing plant in southern Mexico. The paper describes innovative and cost-effective use of passive (non-intrusive) and active (intrusive) techniques, including the use of compound-specific analytical methods for site characterization. The techniques used, on a demonstrative basis, include geophysical, geochemical, and borehole drilling. Geochemical techniques used to delineate the horizontal extent of hydrocarbon contamination at the site include soil gas surveys. The borehole drilling technique used to assess the vertical extent of contamination and confirm geophysical and geochemical data combines conventional hollow-stem auguring with direct push-probe using Geoprobe. Compound-specific analytical methods, such as hydrocarbon fingerprinting and a modified method for gasoline range organics, demonstrate the inherent merit and need for such analyses to properly characterize a site, while revealing the limitations of noncompound-specific total petroleum hydrocarbon analysis. The results indicate that the techniques used in tandem can properly delineate the nature and extent of contamination at a site; often supplement or complement data, while reducing the risk of errors and omissions during the assessment phase; and provide data constructively to focus site-specific remediation efforts. 7 figs.

  14. A planning model for petroleum refineries

    Directory of Open Access Journals (Sweden)

    Pinto J.M.

    2000-01-01

    Full Text Available The main objective of this paper is to develop a nonlinear planning model for refinery production. The model described here represents a general petroleum refinery and its framework allows the implementation of nonlinear process models as well as blending relations. This model assumes the existence of several processing units, producing a variety of intermediate streams, with different properties, that can be blended to constitute the desired kinds of products. Two real-world applications are developed, one for the planning of diesel production in the RPBC refinery in Cubatão (SP and the other for the general production planning in the REVAP refinery in S. José dos Campos (SP. In both cases, different market scenarios were analyzed using the planning optimization and the results were compared with the current situation, in which there is no extensive use of planning decision support tools. Results revealed that there is a very large potential of profitability embedded in the planning activity, reaching several millions of dollars per year.

However, after the Iraq conflict, new regional situations are changing. China, for instance, with its growing up demand, will change the physiognomy of the oil market. In parallel, from Indonesia to Africa, petroleum and religion interfere and explain the new conflict areas. As for the US strategy, which is not limited to the energy paradigm, it largely integrates energy in the main lines of its diplomacy, from the 'Wide Middle East' to the 'Sahel initiative', and in its position with respect to Venezuela.

    The Ministry of Petroleum and Energy produces an annual environmental review in cooperation with the Norwegian Petroleum Directorate. The purpose of this publication is threefold: (1) to increase knowledge about the environmental aspects of Norwegian oil and gas activities, (2) to take a more detailed look at a specific topic which particularly concerns both the industry and the authorities, and identify the challenges and options faced, (3) to emphasise the governments goal of ensuring that Norway reconciles its role as a large energy producer with a pioneering position on environmental issues. This year's edition focuses on the topic of ''oil and fish - common sea''. Both the petroleum and fishing industries depend on the waters off Norway. Ever since petroleum activities began on the Norwegian continental shelf more than 30 years ago, the authorities have been keen to ensure that these two sectors can work in the same sea areas. What challenges and opportunities face the petroleum industry over discharges to the sea and living marine resources? How can the authorities ensure that this sector is able to coexist with the fisheries? These and similar questions about the relationship between the petroleum and fishing industries in their shared seas are covered in section two of this publication. Environment 2002 also incorporates a factual section, which covers the status of emissions/discharges, environmental impacts and measures to reduce discharges to the sea and emissions to the air from petroleum activities. The MPE hopes that a publication of this kind can enhance basic knowledge about petroleum activities and environmental issues.

    How much of the total Norwegian emissions to air comes from the petroleum sector? What is the Norwegian petroleum industry's contribution to the discharges to sea? How do the Norwegian authorities manage the environmental aspects relating to the petroleum industry? What does nmVOC mean? In co-operation with the Norwegian Petroleum Directorate the Norwegian Ministry of Petroleum and Energy issues this publication to answer questions such as these. We furthermore wish to provide comprehensive information about the environmental aspects relating to the Norwegian oil and gas operations. It is also important to demonstrate that the efforts to improve environmental efficiency in this industry is a continuous process and that measures have already been implemented to this effect. Each year we take a closer look at one topic which is of concern to the petroleum industry. In light of the new protocol under the Convention of Long-range Transboundary Air Pollution, we wish to focus on the offshore sectors emission of NO{sub x} in this issue and on the possibilities and challenges we face in this context. This publication also contains a section containing factual data, which i.a. describes the status of discharges and emissions, environmental effects and measures to reduce the emission of CO{sub 2}, NO{sub x}, nmVOC and the discharge of oil and chemicals. We hope that a publication like this will increase the public's general knowledge of how the petroleum industry addresses environmental issues. An important task of the Ministry of Petroleum and Energy is to help formulate general guidelines and measures in areas where energy policy and environmental policy interact. It is furthermore our aim to help Norway combine her role as a major oil producer of energy with the role of being a leader in the protection of the environment.

    The frontier basins of Colombia with hydrocarbon potential are numerous, have varying geological histories, and are in different stages of exploration development. In this paper, sedimentary or structural basins are classified as frontier petroleum basins if commercial discoveries of hydrocarbons are lacking, if the basin has not attained a high degree of exploration development, or if a new play concept has been perceived or developed for a portion of a mature exploration basin. Using these criteria for classification, the authors discuss the Cauca-Patia Choco-Pacifico, and Lower Magdalena basin complexes; the Cordillera Oriental foreland basin; and the Cesar-Rancheria, Sabana, and Amazonas basins. A comprehensive geological and structural setting of each of these frontier basins will be presented. The depositional and tectonic evolution of the basins will be highlighted, and the play concepts for each will be inventoried, catalogued, and categorized as to whether they are theoretical or established. The discussion of the available plays in each of these basins will include the main play concept elements of reservoirs traps, seals, source rocks, maturation, and timing. When detailed data permit, the reservoir and trap geometry will be presented.

    Many current Web-based learning environments facilitate the theoretical teaching of a subject but this may not be sufficient for those disciplines that require a significant use of graphic mechanisms to resolve problems. This research study looks at the use of an environment that can help students learn engineering drawing with Web-based CAD tools, including a self-correction component. A comparative study of 121 students was carried out. The students were divided into two experimental groups using Web-based interactive CAD tools and into two control groups using traditional learning tools. A statistical analysis of all the samples was carried out in order to study student behavior during the research and the effectiveness of these self-study tools in the learning process. The results showed that a greater number of students in the experimental groups passed the test and improved their test scores. Therefore, the use Web-based graphic interactive tools to learn engineering drawing can be considered a significant improvement in the teaching of this kind of academic discipline.

    Full Text Available The learning and development of teamwork skill is onlypossible if its achievement is a self-building process of the student. In turn,the teachers must become guides in the process of a learning which is notlimited only to the topic of their own course, but which must be imbedded witha good dose of this skill. Promotionof teamwork is not spontaneous but very often requires the use ofself-regulation within teams. The aim of the paper is to elucidateif positive or negative self-regulation of teams are useful to promoteteamwork. The paper presents some experiences onthe use of self-regulation of teams within ofactive teaching strategies that involve teamwork as a criticalskill in engineering education. The paper presents first the fundamentals ofthe learning strategy adopted, intended to develop teamwork abilities in thestudents. It then describes the context and challenges faced up in the casestudies, as well as the essentials of the learning activities proposed.Finally, the paper discusses the student’s achievement and perception. Althoughsome influence of unbalanced teams there exists, it can be stated that positiveself-regulation of teams is more easily accepted by teams than the negative ones,because of the influence on interpersonal relationships amongst students. Thetopics involved in this experience are energy related topics such as electricalinstallations, heat transfer, engineering thermodynamics or theory of circuits.

    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.

    Full Text Available Electrical engineering concepts are abstract in nature and difficult to explain using conventional teaching tools. The use of software in teaching holds the potential in providing better learning support as these tools can provide visual representations of complex circuits operation and waveforms for enhanced concept and procedural learning in power electronics. The software packages available for simulation of power electronic circuits include MATLAB, PSPICE and PSIM. In this study the author takes an example of an AC voltage controller to explain the software based teaching approach. The author used two software based simulation tools to explain the AC voltage controller concept and compare the software based approach with the blackboard and power point presentation based technique. Results of different approaches are compared in the last session of this paper, so it is helpful for the faculty of electrical engineering to find the various applications of MATLAB, SIMULINK and PSIM in teaching. Overall students find the simulation approach is helpful for their learning.

    Active learning methods can be appropriate in engineering, as their methodology promotes meta-cognition, independent learning and problem-solving skills. Problem-based learning is the educational process by which problem-solving activities and instructor's guidance facilitate learning. Its key characteristic involves posing a 'concrete problem' to initiate the learning process, generally implemented by small groups of students. Many universities have developed and used active methodologies successfully in the teaching-learning process. During the past few years, the University of the Basque Country has promoted the use of active methodologies through several teacher training programmes. In this paper, we describe and analyse the results of the educational experience using the problem-based learning (PBL) method in a physics course for undergraduates enrolled in the technical telecommunications engineering degree programme. From an instructors' perspective, PBL strengths include better student attitude in class and increased instructor-student and student-student interactions. The students emphasised developing teamwork and communication skills in a good learning atmosphere as positive aspects.

    An excess of lympho-haematopoietic (LH) cancers has been identified in the Australian petroleum industry through the Health Watch surveillance programme. A nested case-control study is being conducted to investigate this excess. This paper describes the methods used to provide quantitative estimates of benzene exposure for each of the subjects in the case-control study. Job histories were compiled for each subject from interviews and company employment records. Site visits and telephone interviews were used to identify the tasks included in each job title. Details about the tasks such as their frequency, the technology in use and about changes that had taken place over the years were also gathered. Exposure dated back to the late 1940s for a few subjects. Collaborating petroleum companies provided recent benzene exposure monitoring data. These were used to generate Base Estimates of exposure for each task, augmented with data from the literature where necessary. Past exposures were estimated from the Base Estimates by means of an exposure algorithm. The modifying effects of technological changes and changes to the product were used in the algorithm. The algorithm was then computed to give, for each job, for each subject, an estimate of average benzene exposure in ppm in the workplace atmosphere (Workplace Estimate). This value was multiplied by the years for which the job was held and these values summed to give an estimate of Cumulative Estimate of benzene in ppm-years. The occupational hygienists performing the exposure assessment did so without knowledge of the case or control status of subjects. Overall exposures to benzene in the Australian petroleum industry were low, and virtually all activities and jobs were below a time-weighted average of 5 ppm. Exposures in terminals were generally higher than at refineries. Exposures in upstream areas were extremely low. Estimates of Cumulative Estimate to benzene ranged from 0.005 to 50.9 ppm-years.

    In the twenty-first century, the urgent problems the world is facing (the UN Sustainable Development Goals) are increasingly related to vast and intricate 'systems of systems', which comprise both socio-technical and eco-systems. In order for engineers to adequately and responsibly respond to these problems, they cannot focus on only one technical or any other aspect in isolation, but must adopt a wider and multidisciplinary perspective of these systems, including an ethical and social perspective. Engineering curricula should therefore focus on what we call 'comprehensive engineering'. Comprehensive engineering implies ethical coherence, consilience of scientific disciplines, and cooperation between parties.

    Full Text Available Selecting the plant species to grow on aged petroleum hydrocarbons polluted soils is an important factor for a successful phytoremediation. Phytoremediation is a green technology that can become a promising solution for decontaminating polluted soils and ecological restoration of the landscape. Our comparative studies evaluate the effect of oil hydrocarbon pollution with high initial concentration on the growth leguminous plant species: Vicia sativa and Glycine max. The experimental block contains control variants, polluted soil unfertilized / fertilized with municipal sludge anaerobically stabilized in absence/presence of modified volcanic tuff amendment. After period of time the experiment’s soil in which plant species had grown well was sampled and analyzed for petroleum hydrocarbons removal. Both species showed promising efficiency in the phytoremediation of petroleum hydrocarbon highly polluted soils but a reduced growth of the surveyed plants was noticed. The efficiency of the petroleum hydrocarbons diminution is increased in the case of the addition of fertilizer 16.6 % for Vicia sativa and 30 % for Glycine max vs. the initial quantity. In the case of the phytoremediation of polluted soils treated with fertilizer and volcanic tuff, the efficiency of the petroleum hydrocarbons reduction was 72.9 % for Vicia sativa and 53.7 % for Glycine max.

    This article discusses the influence of environmental regulation on the adoption of new production techniques and on the improvement of existing techniques in the refining petroleum industry, namely at the Paulinia refinery (REPLAN). Describes the techniques adopted in order to fit refining processes into the regulation about environmental impacts (related to the protection of resources like water, air and soil), and also techniques adopted in order to produce less pollutant diesel and gasoline. This article has support on bibliographic research and data collected in REPLAN and CENPES, which permit characterize technologies adopted in REPLAN at the end of the 90s and the regulatory rules that drive them. The regulation is presented under an evolutionary approach, considering that technology develops along whit the socio-economic context, the environmental regulation is a related element which determines the search and selection of technologies able to comply with regulation ensuring economic viability. Regulation is also a determinant factor for the adoption of innovations in the refining industry. Specifically in REPLAN, the environmental regulation has required large investments in order to comply processes and products with the established standards. (author)

    We study the formalization of a collection of documents created for a Software Engineering project from an MKM perspective. We analyze how document and collection markup formats can cope with an open-ended, multi-dimensional space of primary and secondary classifications and relationships. We show that RDFa-based extensions of MKM formats, employing flexible "metadata" relationships referencing specific vocabularies for distinct dimensions, are well-suited to encode this and to put it into service. This formalized knowledge can be used for enriching interactive document browsing, for enabling multi-dimensional metadata queries over documents and collections, and for exporting Linked Data to the Semantic Web and thus enabling further reuse.

    São Paulo is the largest city in Brazil and one of the largest cities in the world. In 2004, São Paulo City Department of Health decided to implement a Healthcare Information System to support managing healthcare services and provide an ambulatory health record. The resulting information system is one of the largest public healthcare information systems ever built, with more than 2 million lines of code. Although statistics shows that most software projects fail, and the risks for the São Paulo initiative were enormous, the information system was completed on-time and on-budget. In this paper, we discuss the software engineering principles adopted that allowed to accomplish that project's goals, hoping that sharing the experience of this project will help other healthcare information systems initiatives to succeed.

    Muñoz, Enrique; Peña, Francisco J.

    2012-12-01

    We studied the efficiency of two different schemes for a quantum heat engine, by considering a single Dirac particle trapped in an infinite one-dimensional potential well as the “working substance.” The first scheme is a cycle, composed of two adiabatic and two isoenergetic reversible trajectories in configuration space. The trajectories are driven by a quasistatic deformation of the potential well due to an external applied force. The second scheme is a variant of the former, where isoenergetic trajectories are replaced by isothermal ones, along which the system is in contact with macroscopic thermostats. This second scheme constitutes a quantum analog of the classical Carnot cycle. Our expressions, as obtained from the Dirac single-particle spectrum, converge in the nonrelativistic limit to some of the existing results in the literature for the Schrödinger spectrum.

    For a small graduate program in environmental engineering in a rural state in the US, it is important for the program curriculum to stay in the mainstream. While resident student enrollment is approaching a steady level, international student enrollment increases steadily, this is due in part to the out-of-state tuition waiver provided to the students. Part-time students are a significant part of the program, these students have special needs that are different from traditional full-time students that must be taken into consideration in program planning. A small program provides an attentive atmosphere for students' learning, but it also has problems that a larger program would not encounter, such as competitiveness, personal conflicts, program identity, etc. Despite success in the past, the program is likely to merge with other related programs in the university during times of budget restrictions.

    The containment boundaries of most spent-fuel casks certified for use in the United States by the Nuclear Regulatory Commission are constructed with stainless steel, a material that is ductile in an engineering sense at all temperatures and for which, therefore, fracture mechanics principles are not relevant for the containment application. Ferritic materials may fail in a nonductile manner at sufficiently low temperatures, so fracture mechanics principles may be applied to preclude nonductile fracture. Because of the need to transport and store spent nuclear fuel safely in all types of climatic conditions, these vessels have regulatory lowest service temperatures that range down to -40 C (-40 F) for transport application. Such low service temperatures represent a severe challenge in terms of fracture toughness to many ferritic materials. Linear-elastic and elastic-plastic fracture mechanics principles provide a methodology for evaluating ferritic materials under such conditions.

  11. Technology Transfer Challenges: A Case Study of User-Centered Design in NASA's Systems Engineering Culture

    The Upper Stage (US) section of the National Aeronautics and Space Administration's (NASA) Ares I rocket will require internal access platforms for maintenance tasks performed by humans inside the vehicle. Tasks will occur during expensive critical path operations at Kennedy Space Center (KSC) including vehicle stacking and launch preparation activities. Platforms must be translated through a small human access hatch, installed in an enclosed worksite environment, support the weight of ground operators and be removed before flight - and their design must minimize additional vehicle mass at attachment points. This paper describes the application of a user-centered conceptual design process and the unique challenges encountered within NASA's systems engineering culture focused on requirements and "heritage hardware". The NASA design team at Marshall Space Flight Center (MSFC) initiated the user-centered design process by studying heritage internal access kits and proposing new design concepts during brainstorming sessions. Simultaneously, they partnered with the Technology Transfer/Innovative Partnerships Program to research inflatable structures and dynamic scaffolding solutions that could enable ground operator access. While this creative, technology-oriented exploration was encouraged by upper management, some design stakeholders consistently opposed ideas utilizing novel, untested equipment. Subsequent collaboration with an engineering consulting firm improved the technical credibility of several options, however, there was continued resistance from team members focused on meeting system requirements with pre-certified hardware. After a six-month idea-generating phase, an intensive six-week effort produced viable design concepts that justified additional vehicle mass while optimizing the human factors of platform installation and use. Although these selected final concepts closely resemble heritage internal access platforms, challenges from the application of the

    2013-07-01

    Full Text Available Increasingly competitive market environments have forced not only large manufacturing, but also smalland-medium size enterprises (SME to look for means to improve their operations in order to increase competitive strength. This paper presents an adaptation and adoption by a UK SME engineering service organisation, of lean management, industrial engineering, and automation metods developed within larger organisations. This SME sought to improve the overall performance of one of its core testing processes. An exploratory analysis, based on the lean management concept of “value added” and work measurement technique “time study”, was developed and carried out in order to understand the current performance of a testing process for gas turbine fuel flow dividers. A design for the automation of some operations of the testing process was followed as an approach to reduce non-value added activities, and improve the overall efficiency of the testing process. The overall testing time was reduced from 12.41 to 7.93 hours (36.09 percent while the man hours and non-value added time were also reduced from 23.91 to 12.94 hours (45.87 percent and from 11.08 to 6.69 (39.67 percent hours respectively. This resulted in an increase in process efficiency in terms of man hours from 51.91 to 61.28 percent. The contribution of this paper resides in presenting a case study that can be used as a guiding reference for managers and engineers to undertake improvement projects, in their organisations, similar to the one presented in this paper.

  9. THE INTEGRATION OF ENGINEERED AND INSTITUTIONAL CONTROLS: A CASE STUDY APPROACH WITH LESSONS LEARNED FROM PREVIOUSLY CLOSED SITES

    2005-02-01

    Environmental remediation efforts that are underway at hundreds of contaminated sites in the United States will not be able to remediate large portions of those sites to conditions that would permit unrestricted access. Rather, large volumes of waste materials, contaminated soils and cleanup residuals will have to be isolated either in place or in new, often on-site, disposal cells with long term monitoring, maintenance and institutional control needs. The challenge continues to be to provide engineering systems and controls that can ensure the protection of public health and the environment over very long time horizons (hundreds to perhaps thousands of years) with minimal intervention. Effective long term management of legacy hazardous and nuclear waste requires an integrated approach that addresses both the engineered containment and control system itself and the institutional controls and other responsibilities that are needed. Decisions concerning system design, monitoring and maintenance, and the institutional controls that will be employed are best done through a "risk-nformed, performance-based" approach. Such an approach should incorporate an analysis of potential "failure" modes and consequences for all important system features, together with lessons learned from experience with systems already in place. The authors will present the preliminary results of a case study approach that included several sites where contamination isolation systems including institutional controls have been implemented. The results are being used together with failure trees and logic diagrams that have been developed for both the engineered barriers and the institutional controls. The use of these analytical tools to evaluate the potential for different levels of failure and associated consequences will be discussed. Of special interest is the robustness of different approaches to providing long-term protection through redundancy and defense in depth.

    2008-01-01

    Full Text Available Dartmouth’s Critical Moments project is designed to promote discussions among faculty and graduate students about the retention of students, particularly women and minorities, in science, math, and engineering (SME disciplines. The first phase of the ongoing project has been the development of four case stories, which are fictionalized composites drawn from surveys and interviews of real Dartmouth students. The surveyed population was 125 students in general chemistry. Of the 77 who agreed to be interviewed, 61 reported having experienced a critical moment – i.e., a positive or negative event or time that had a significant impact on the student’s academic life. Leading critical moments were a poor grade on an exam; challenge from group work; excitement from an internship; and falling in love with a non-SME discipline from other coursework. Interviews of 13 students who had negative critical moments led to the development of case stories for: Antoinetta ’09, who had a disappointing group experience; Dalila ’08, who was poorly prepared; Greg ’09, who got in over his head in his first year; and Michelle ’08, who was shocked by her result in the first exam. The case stories are being discussed by graduate students, TA and faculty in various workshops at the Dartmouth Center for the Advancement of Learning.

    An analytical model for chatter stability prediction in bull-nose end milling of aero-engine casings is presented in this paper. And the mechanics and dynamics variations due to the complex cutter and workpiece geometry are considered by analyzing the effects of the lead angle on the milling process. Firstly, the tool-workpiece engagement region is obtained by using a previously developed method and divided into several disk elements along the tool-axis direction. Secondly, a 3D dynamic model for stability limit calculation is developed and simplified into a 1D model in normal direction considering only the dominant mode of the workpiece. Then the cutting force coefficients, the start and exit angles corresponding to each disk element are determined. And the total stability lobe diagram is calculated using an iterative algorithm. Finally, several experimental tests are carried out to validate the feasibility and effectiveness of the proposed prediction approach.

    This architecturally significant use case describes how the System acquires meteorological data to build atmospheric models used in automatic and interactive processing of infrasound data. The System requests the latest available high-resolution global meteorological data from external data centers and puts it into the correct formats for generation of infrasound propagation models. The system moves the meteorological data from Data Acquisition Partition to the Data Processing Partition and stores the meteorological data. The System builds a new atmospheric model based on the meteorological data. This use case is architecturally significant because it describes acquiring meteorological data from various sources and creating dynamic atmospheric transmission model to support the prediction of infrasonic signal detection

  20. Culturally responsive engineering education: A case study of a pre-college introductory engineering course at Tibetan Children's Village School of Selakui

    Science.gov (United States)

    Santiago, Marisol Mercado

    Culturally responsive teaching has been argued to be effective in the education of Indigenous youth. This approach emphasizes the legitimacy of a group's cultural heritage, helps to associate abstract academic knowledge with the group's sociocultural context, seeks to incorporate a variety of strategies to engage students who have different learning styles, and strives to integrate multicultural information in the educational contents, among other considerations. In this work, I explore the outcomes of a culturally responsive introductory engineering short course that I developed and taught to Tibetan students at Tibetan Children's Village of Selakui (in Uttarakhand, India). Based on my ethnographic research in Tibetan communities in northern India, I examine two research questions: (a) What are the processes to develop and implement a pre-college culturally responsive introductory engineering course? and (b) How do Tibetan culture and Buddhism influence the engineering design and teamwork of the pre-college Tibetan students who took the course? I designed then taught the course that featured elementary lectures on sustainability, introductory engineering design, energy alternatives, and manufacturing engineering. The course also included a pre-college engineering design project through which Tibetan high school students investigated a problem at the school and designed a possible solution to it. Drawing from postcolonial studies, engineering studies, engineering and social justice, Buddhist studies, and Tibetan studies, I provide an analysis of my findings. Based on my findings, I conclude that my culturally responsive approach of teaching was an effective method to help students feel that their cultural background was respected and included in a pre-college engineering course; however, some students felt resistance toward the teaching approach. In addition, the culturally relevant content that connected with their ways of living in their school, Tibetan
