The Coolness of Capitalism Today

Directory of Open Access Journals (Sweden)

Jim McGuigan

2012-05-01

Full Text Available This paper is about the reconciliation of cultural analysis with political economy in Marxist-inspired research on communications. It traces how these two traditions became separated with the development of a one-dimensional and consumerist cultural studies, on the one-hand, and a more classically Marxist political economy of communications, on the other hand, that was accused of holding a simplistic and erroneous concept of ideology. The paper defends a conception of ideology as distorted communication motivated by unequal power relations and sketches a multidimensional mode of cultural analysis that takes account of the moments of production, consumption and textual meaning in the circulation of communications and culture. In accordance with this framework of analysis, the cool-capitalism thesis is outlined and illustrated with reference to Apple, the ‘cool’ corporation. And, the all-purpose mobile communication device is selected as a key and urgent focus of attention for research on commodity fetishism and labour exploitation on a global scale today.

Neutrinos today

International Nuclear Information System (INIS)

Pontecorvo, B.; Bilen'kij, S.

1987-01-01

After the famous 1983 discovery of intermediate W, Z 0 bosons it may be stated with certainty that W, Z 0 are entirely responsible for the production of neutrinos and for their interactions. Neutrino physics notions are presented from this point of view in the first four introductory, quite elementary, paragraphs of the paper. The following seven paragraphs are more sophisticated. They are devoted to the neutrino mass and neutrino mixing question, which is the most actual problem in today neutrino physics. Vacuum neutrino oscillations, matter neutrino oscillations and netrinoless double-decay are considered. Solar neutrino physics is discussed in some detail from the point of view of vacuum and matter neutrino oscillations. The role played by neutrinos in the Universe is briefly considered. In the last paragraph there discussed the probable observation by different groups of neutrinos connected with the Supernova 1987 A: the first observation of gravitational star collapse (at least the general rehearsal of such observation) opens up a new era in astronomy of today exerimental physics and astrophysics is presented at the end of the paper in the form of a Table

Gilson, Krapiec and Christian Philosophy Today

Directory of Open Access Journals (Sweden)

Pawel Tarasiewicz

2015-12-01

Full Text Available The author undertakes an attempt to answer the following question: is Christian philosophy possible today? The question seems to be of great importance due to the fact that what Christians who try to do philosophy usually encounter is bitter criticism which comes to them from two sides at once: that of academy and that of the Church. In short, for academy their philosophy is too Christian, and for the Church it is too academic. Being indebted to the insights of Étienne Gilson and Mieczyslaw A. Krapiec (the original Polish spelling: Mieczysław Albert Krąpiec, pronounced: myechisuaf albert krompyetz, the author comes to the conclusion thatChristian philosophy is possible today only if: 1 it isnot identified with the art of persuasion, as its final end lies in gaining understanding rather than being convincing, 2 itis the work of a Christian, and 3 it has thereal world as its object and metaphysics as its method. ForChristian philosophy—which in essence consists indoing philosophy by Christians in order to get morerational understanding of their religious faith—shouldbe identified with theperfection of the intellect achieved by practicingthe classical philosophy of being.

Review of best estimate plus uncertainty methods of thermal-hydraulic safety analysis

International Nuclear Information System (INIS)

Prosek, A.; Mavko, B.

2003-01-01

In 1988 United States Nuclear Regulatory Commission approved the revised rule on the acceptance of emergency core cooling system (ECCS) performance. Since that there has been significant interest in the development of codes and methodologies for best-estimate loss-of-coolant accident (LOCAs) analyses. Several new best estimate plus uncertainty methods (BEPUs) were developed in the world. The purpose of the paper is to review the developments in the direction of best estimate approaches with uncertainty quantification and to discuss the problems in practical applications of BEPU methods. In general, the licensee methods are following original methods. The study indicated that uncertainty analysis with random sampling of input parameters and the use of order statistics for desired tolerance limits of output parameters is today commonly accepted and mature approach.

Pedrò, Francesc

2012-01-01

In all OECD countries, digital media and connectedness are integral to the lives of todays learners. It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

A comparative critical study between FMEA and FTA risk analysis methods

Science.gov (United States)

Cristea, G.; Constantinescu, DM

2017-10-01

Today there is used an overwhelming number of different risk analyses techniques with acronyms such as: FMEA (Failure Modes and Effects Analysis) and its extension FMECA (Failure Mode, Effects, and Criticality Analysis), DRBFM (Design Review by Failure Mode), FTA (Fault Tree Analysis) and and its extension ETA (Event Tree Analysis), HAZOP (Hazard & Operability Studies), HACCP (Hazard Analysis and Critical Control Points) and What-if/Checklist. However, the most used analysis techniques in the mechanical and electrical industry are FMEA and FTA. In FMEA, which is an inductive method, information about the consequences and effects of the failures is usually collected through interviews with experienced people, and with different knowledge i.e., cross-functional groups. The FMEA is used to capture potential failures/risks & impacts and prioritize them on a numeric scale called Risk Priority Number (RPN) which ranges from 1 to 1000. FTA is a deductive method i.e., a general system state is decomposed into chains of more basic events of components. The logical interrelationship of how such basic events depend on and affect each other is often described analytically in a reliability structure which can be visualized as a tree. Both methods are very time-consuming to be applied thoroughly, and this is why it is oftenly not done so. As a consequence possible failure modes may not be identified. To address these shortcomings, it is proposed to use a combination of FTA and FMEA.

2016-01-01

Full Text Available In the world today for the exploitation of oil reservoirs by artificial lift methods are applied different types of deep pumps (piston, centrifugal, screw, hydraulic, water jet pumps and gas lift (continuous, intermittent and plunger. Maximum values of oil production achieved by these exploitation methods are significantly different. In order to select the optimal exploitation method of oil well, the multicriteria analysis models are used. In this paper is presented an analysis of the multicriteria model's application known as VIKOR, TOPSIS, ELECTRE, AHP and PROMETHEE for selection of optimal exploitation method for typical oil well at Serbian exploration area. Ranking results of applicability of the deep piston pumps, hydraulic pumps, screw pumps, gas lift method and electric submersible centrifugal pumps, indicated that in the all above multicriteria models except in PROMETHEE, the optimal method of exploitation are deep piston pumps and gas lift.

Lebovits, Allen

2012-09-01

There are many external influences in today's market force that impair the relationship between the pain medicine specialist and the patient, and ultimately prevent optimal quality of care. This article explores the ethical challenges facing the pain medicine specialist in today's increasingly "business" environment and will offer solutions for maintaining the professionalism of pain medicine. Four commonly encountered bioethical principles in the practice of pain medicine are reviewed: beneficence, nonmaleficence, justice, and autonomy. The following ethical challenges of the pain medicine specialist are reviewed: practicing outside ones specialty area, practice characteristics, the consultant role, the economic lure of aggressive intervention, not evaluating for and treating comorbid psychopathology, reimbursement pressures, workers' compensation, and use of unproven methods. Solutions offered include collegial associations, social responsibility, legislative initiatives, pain education, interdisciplinary evaluation and treatment, improved relationships with third-party payers, reduced racial disparities, and ethics education. Ethics is the "roadmap" that enables the pain medicine specialist to navigate the increasingly murky waters of practicing pain management today by maintaining the professionalism necessary to combat today's "business" pressures.

2004-09-01

Full Text Available Years ago, exploration was done through surface observations and „divining rods“ – now, it is done by satellites, microprocessors, remote sensing, and supercomputers. In the 1970´ s, the exploration success rate was 14 percent, today, it is nearly 29 percent. Not so long ago, three – dimension (3D seismic diagnostic techniques helped recover 25-50 percent of the oil in place – now, 4D seismic helps recover up to 70 percent of the oil in place. 3D and 4D seismic and earth imaging systems also help in understanding the subsurface flow of other fluids, such as groundwater and pollutants.Seismic surveys – a technique in which sound waves are bounced off underground rock struktures to reveal possible oil and gas bearing formation – are now standard fare for the modern petroleum industry. But today’s seismic methods are best at locating „structural traps“ where faults or folds in the underground rock have created zones where oil can become trapped.

Nuclear energy today

International Nuclear Information System (INIS)

2003-01-01

Energy is the power of the world's economies, whose appetite for this commodity is increasing as the leading economies expand and developing economies grow. How to provide the energy demanded while protecting our environment and conserving natural resources is a vital question facing us today. Many parts of our society are debating how to power the future and whether nuclear energy should play a role. Nuclear energy is a complex technology with serious issues and a controversial past. Yet it also has the potential to provide considerable benefits. In pondering the future of this imposing technology, people want to know. - How safe is nuclear energy? - Is nuclear energy economically competitive? - What role can nuclear energy play in meeting greenhouse gas reduction targets? - What can be done with the radioactive waste it generates? - Does its use increase the risk of proliferation of nuclear weapons? - Are there sufficient and secure resources to permit its prolonged exploitation? - Can tomorrow's nuclear energy be better than today's? This publication provides authoritative and factual replies to these questions. Written primarily to inform policy makers, it will also serve interested members of the public, academics, journalists and industry leaders. (author)

Application of WSP method in analysis of environmental samples

International Nuclear Information System (INIS)

Stacho, M.; Slugen, V.; Hinca, R.; Sojak, S.; Krnac, S.

2014-01-01

Detection of activity in natural samples is specific especially because of its low level and high background interferences. Reduction of background interferences could be reached using low background chamber. Measurement geometry in shape of Marinelli beaker is commonly used according to low level of activity in natural samples. The Peak Net Area (PNA) method is the world-wide accepted technique for analysis of gamma-ray spectra. It is based on the net area calculation of the full energy peak, therefore, it takes into account only a fraction of measured gamma-ray spectrum. On the other hand, the Whole Spectrum Processing (WSP) approach to the gamma analysis makes possible to use entire information being in the spectrum. This significantly raises efficiency and improves energy resolution of the analysis. A principal step for the WSP application is building up the suitable response operator. Problems are put in an appearance when suitable standard calibration sources are unavailable. It may be occurred in the case of large volume samples and/or in the analysis of high energy range. Combined experimental and mathematical calibration may be a suitable solution. Many different detectors have been used to register the gamma ray and its energy. HPGe detectors produce the highest resolution commonly available today. Therefore they are they the most often used detectors in natural samples activity analysis. Scintillation detectors analysed using PNA method could be also used in simple cases, but for complicated spectra are practically inapplicable. WSP approach improves resolution of scintillation detectors and expands their applicability. WSP method allowed significant improvement of the energetic resolution and separation of "1"3"7Cs 661 keV peak from "2"1"4Bi 609 keV peak. At the other hand the statistical fluctuations in the lower part of the spectrum highlighted by background subtraction causes that this part is still not reliably analyzable. (authors)

The Prospects of Radical Change Today

Directory of Open Access Journals (Sweden)

Slavoj Žižek

2018-05-01

Full Text Available In this contribution, Slavoj Žižek takes the occasion of Marx’s bicentenary for reflecting on the prospects of radical change today. First, it is shown that under Stalinism, Lenin’s works were quoted out of context in an arbitrary way in order to legitimise arbitrary political measures. Marxism thereby became an ideology that justified brutal subjective interventions. Second, this contribution poses the question of the revolutionary subject and democracy today. It stresses the role of both contingency and strategy in revolutions. In political assemblages taking place on public squares, the inert mass of ordinary people is transubstantiated into a politically engaged united force. The basic political problem today is how to best reconfigure democracy. Third, this contribution analyses the “interesting times” we live in. These are times that feature multiple crises, right-wing populism à la Donald Trump and Marine Le Pen, the lower classes’ opposition to immigration, and the refugee crisis. Questions about human rights and their violation and about radical change need to be asked in this context.

After a longer starting period many radiation techniques have prevailed practically. Today radiation processes are usual components of chemistry, biology, medicine, and technologies in the most common sense. This paper deals with the latest state of radiation chemistry, whereas the possible practical applications are in the foreground of discussion as to reach mainly practicians in laboratory and industry. But also physicians, pharmacists and chemical engineers should be informed about the possibilities of application of high energyy radiation. Because radiation chemistry has also enriched works of related subjects, for example physical, organic and inorganic chemistry, this paper will also be of interest for experts of these disciplines.

Methods of Cinematic Narrative in Today’s Ghazal

Directory of Open Access Journals (Sweden)

Mohsen Mohammadi fesharaki

2014-07-01

Full Text Available  Abstract With Highlighted presence of video m edia in society, its impact on other branches of art and poetry is seen more than before. At the beginning of being familiar with movie in Iran's traditional society, the subject was somehow a taboo and there was no trace of its influence on literature. Due to their poets' worldview, Nimaian poetry and subsequently blank verse reconciled with cinema earlier than classical poetry , but after Iran revolution and deep transformations resulting from war, Ghazal considered cinema and methods of narrative in cinema with a new look. This process is clearly evident in the lyric poets of the post- revolution.  Narrative  "In the simplest sense, narrative is a story that occurs during time and the narrator is one who narrates the story" (Khalil, 1383: p 107. Better expressed, "The story is what is said and narration is how to say it" (Afkhami, 1382: p 59. One of the main concerns of Nima is entering narrative element as an effective actor in poetry, but perhaps as intensely as contemporary poets of Ghazal have noticed to this Nima's advice, today his followers do not.   Narrative in Persian poetry   Narratives form a large part of Persian literature . Narrative poem dates back to the first versified epics . In Persian , narrative poetry is often versified in the form of couplet-poem and in two meter of Motaghareb and Hazaj as follows :   1 - " national epic narratives   2 - historical narratives   3 - love and public narratives   4 - allegorical or moral narratives "( Dad, 13 80: narrative poetry entry   Characteristics of narrative Ghazal   1- The first outcome of narrative Ghazal is the strength of its vertical axis . This artistically makes Ghazal a systematic and coherent structure in which verse or hemistich is no more a semantic unit , but all parts of poem carries the burden of meaning of the poem , so verses can no longer move or change .   2

Purpose of this research is defining requirements to benchmarking methods of assessing national or regional innovation systems and compare them basing on assumption, that innovation system is aligned with sustainable development concept. Analysis of goal sets and concepts, which underlie observed international composite innovation indexes, comparison of their metrics and calculation techniques, allowed us to reveal opportunities and limitations of using these methods in frames of sustainable development concept. We formulated targets of innovation development on the base of innovation priorities of sustainable socio-economic development. Using comparative analysis of indexes with these targets, we revealed two methods of assessing innovation systems, maximally connected with goals of sustainable development. Nevertheless, today no any benchmarking method, which meets need of innovation systems assessing in compliance with sustainable development concept to a sufficient extent. We suggested practical directions of developing methods, assessing innovation systems in compliance with goals of societal sustainable development.

Applications of Automation Methods for Nonlinear Fracture Test Analysis

Science.gov (United States)

Allen, Phillip A.; Wells, Douglas N.

2013-01-01

Using automated and standardized computer tools to calculate the pertinent test result values has several advantages such as: 1. allowing high-fidelity solutions to complex nonlinear phenomena that would be impractical to express in written equation form, 2. eliminating errors associated with the interpretation and programing of analysis procedures from the text of test standards, 3. lessening the need for expertise in the areas of solid mechanics, fracture mechanics, numerical methods, and/or finite element modeling, to achieve sound results, 4. and providing one computer tool and/or one set of solutions for all users for a more "standardized" answer. In summary, this approach allows a non-expert with rudimentary training to get the best practical solution based on the latest understanding with minimum difficulty.Other existing ASTM standards that cover complicated phenomena use standard computer programs: 1. ASTM C1340/C1340M-10- Standard Practice for Estimation of Heat Gain or Loss Through Ceilings Under Attics Containing Radiant Barriers by Use of a Computer Program 2. ASTM F 2815 - Standard Practice for Chemical Permeation through Protective Clothing Materials: Testing Data Analysis by Use of a Computer Program 3. ASTM E2807 - Standard Specification for 3D Imaging Data Exchange, Version 1.0 The verification, validation, and round-robin processes required of a computer tool closely parallel the methods that are used to ensure the solution validity for equations included in test standard. The use of automated analysis tools allows the creation and practical implementation of advanced fracture mechanics test standards that capture the physics of a nonlinear fracture mechanics problem without adding undue burden or expense to the user. The presented approach forms a bridge between the equation-based fracture testing standards of today and the next generation of standards solving complex problems through analysis automation.

The most important contributions of Einstein involve 5 fields of physics : the existence of quanta (light quanta, stimulated radiation emission and Bose-Einstein condensation), relativity, fluctuations (Brownian motion and thermodynamical fluctuations), the basis of quantum physics and cosmology (cosmological constant and the expansion of the universe). Diverse and renowned physicists have appreciated the development of modern physics from Einstein's ideas to the knowledge of today. This book is a collective book that gathers their work under 7 chapters: 1) 1905, a new beginning; 2) from the Einstein, Podolsky and Rosen's article to quantum information (cryptography and quantum computers); 3) the Bose-Einstein condensation in gases; 4) from stimulated emission to the today's lasers; 5) Brownian motion and the fluctuation-dissipation theory; 6) general relativity; and 7) cosmology.

Challenging today's nuclear industry to be competitive in a changing tomorrow

International Nuclear Information System (INIS)

Plug, B.

1996-01-01

As the millennium approaches, the future of the nuclear power generation appears desolate. Today's nuclear executives are facing challenges resulting from worldwide change and have forced utilities to reevaluate their corporation's future directions. The nuclear industry must be competitive more than ever to address today's rapid changing marketplace and pressures exerted from: regulatory reformation; increased competition; changes in technology; customer evolution; and globalization. These factors have compelled nuclear executives to address questions such as: What impact will these changes have on today's marketplace, and on my corporation? What will characterize tomorrow's successful nuclear facility? How can today's nuclear corporation compete in tomorrow's marketplace? Will my corporation survive? (author)

Decomposition method for analysis of closed queuing networks

Directory of Open Access Journals (Sweden)

Yu. G. Nesterov

2014-01-01

Full Text Available This article deals with the method to estimate the average residence time in nodes of closed queuing networks with priorities and a wide range of conservative disciplines to be served. The method is based on a decomposition of entire closed queuing network into a set of simple basic queuing systems such as M|GI|m|N for each node. The unknown average residence times in the network nodes are interrelated through a system of nonlinear equations. The fact that there is a solution of this system has been proved. An iterative procedure based on Newton-Kantorovich method is proposed for finding the solution of such system. This procedure provides fast convergence to solution. Today possibilities of proposed method are limited by known analytical solutions for simple basic queuing systems of M|GI|m|N type.

Psychoanalysis today

FONAGY, PETER

2003-01-01

The paper discusses the precarious position of psychoanalysis, a therapeutic approach which historically has defined itself by freedom from constraint and counted treatment length not in terms of number of sessions but in terms of years, in today's era of empirically validated treatments and brief structured interventions. The evidence that exists for the effectiveness of psychoanalysis as a treatment for psychological disorder is reviewed. The evidence base is significant and growing, but less than might meet criteria for an empirically based therapy. The author goes on to argue that the absence of evidence may be symptomatic of the epistemic difficulties that psychoanalysis faces in the context of 21st century psychiatry, and examines some of the philosophical problems faced by psychoanalysis as a model of the mind. Finally some changes necessary in order to ensure a future for psychoanalysis and psychoanalytic therapies within psychiatry are suggested. PMID:16946899

Velocity measurement technology can be traced back to the pitot tube velocity measurement method in the 18th century and today's velocity measurement technology use the acoustic and radar technology, with the Doppler principle developed technology advances, in order to develop the measurement method is more suitable for the measurement of velocity, the purpose is to get a more accurate measurement data and with the surface velocity theory, the maximum velocity theory and the indicator theory to obtain the mean velocity. As the main research direction of this article is to review the literature of the velocity measurement techniques and analysis methods, and to explore the applicability of the measurement method of the velocity measurement instruments, and then to describe the advantages and disadvantages of the different mean velocity profiles analysis method. Adequate review of the references of this study will be able to provide a reference for follow-up study of the velocity measurement. Review velocity measurement literature that different velocity measurement is required to follow the different flow conditions measured be upgraded its accuracy, because each flow rate measurement method has its advantages and disadvantages. Traditional velocity instrument can be used at low flow and RiverRAD microwave radar or imaging technology measurement method may be applied in high flow. In the tidal river can use the ADCP to quickly measure river vertical velocity distribution. In addition, urban rivers may be used the CW radar to set up on the bridge, and wide rivers can be used RiverRAD microwave radar to measure the velocities. Review the relevant literature also found that using Ultrasonic Doppler Current Profiler with the Chiu's theory to the velocity of observing automation work can save manpower and resources to improve measurement accuracy, reduce the risk of measurement, but the great variability of river characteristics in Taiwan and a lot of drifting floating

Full text: Recently, much attention is paid to the research and development of effective metal remediation methods. In industry, for the removal of metals from the industrial solutions and wastes, the expensive ion-exchange resin method of metal sorption is used today. The microbiological methods are much less expensive, are available and provide its application in natural conditions. The search for molybdenum bio sorbent was performed amongst Actinomyces strains. The 18 of Streptomyces strains were used. The data showed that all investigated strains uptake the molybdenum from the solution in various degrees. The molybdenum determination was performed using neutron activation analysis technique. In a nuclear reactor, the samples were treated with a steady flow of neutrons (5.1·10 13 ) n·cm -2 sec -1 in 20 hours. The samples were stored for 6-7 days before analysis. The Actinomyces biomass uptake capacity was up to 94.5 %. The 8 cultures have the most high uptake capacity that varied from 87.4 to 94.5 %. Streptomyces sp. 39 and Streptomyces sp.32 have the lowest bio-sorption capacity amongst studied strains, which was 46.6% and 40 % respectively, whereas the bio sorption capacity of other cultures varied from 55.8 to 64.1%. The influence of some physical and chemical parameters (culture age, pH, temperature) on molybdenum bio-sorption was studied. Data showed that the change in pH, temperature and cultivation period lead to the increase of bio-sorption capacity

If the super conductor industry settles out at a temperature of -100 0 F or above, mechanical refrigeration will be vying for the cooling business. Today there very definitely is a break point in the application of equipment at approximately -120 0 F or 189 0 K. Other technologies are generally utilized below this level. However, with market potential comes invention and breakthroughs in refrigeration can also occur. Today standard refrigeration systems are cost effective, reliable and produced in the millions for high temperature applications of +10 0 F to +40 0 F evaporator temperature. Lower temperatures require additional hardware, consume additional power and are produced today in limited quantities for special applications

Full Text Available Chloropropanols are known as undesired food contaminants liberated during the processing of various food products. When the adverse effects of chloropropanols, especially 3-monochloropropane-1,2-diol (3-MCPD, 2-monochloropropane-1,3-diol (2-MCPD and glycidols along with their esters were first understood, the studies about the detection and mitigation of these compounds were accelerated. 3-MCPD, which was detected in food products in higher amounts when compared to other chloropropanols, usually occurs during refining process of vegetable oils, especially in deodorisation step. The novel methods in terms of the analysis of 3-MCPD and other chloropropanols are continuously updated. However, there are two basic methods today namely direct and indirect methods. Direct methods enable to detect all of the esters individually, yet, due to the necessity of a huge number of reference standards, indirect methods are currently more preferred. The first essential step of reducing chloropropanols in food products is to determine the proper analysis method. In this review, general information, new developments in analysis methods, mitigation studies and the toxigolocial data about various chloropropanols were summarized.

The worldwide market for superconductive products may exceed $1 billion in 1987. These products are expanding the frontiers of science, revolutionizing the art of medical diagnosis, and developing the energy technology of the future. In general, today's customers for superconductive equipment want the highest possible performance, almost regardless of cost. The products operate within a few degrees of absolute zero, and virtually all are fabricated from niobium or niobium alloys-so far the high-temperature superconductors discovered in 1986 and 1987 have had no impact on these markets. The industry shows potential and profound societal impact, even without the new materials

Corrosion issues in nuclear industry today

International Nuclear Information System (INIS)

Cattant, F.; Crusset, D.; Feron, D.

2008-01-01

In the context of global warming, nuclear energy is a carbon-free source of power and so is a meaningful option for energy production without CO 2 emissions. Currently, there are more than 440 commercial nuclear reactors, accounting for about 15% of electric power generation in the world, and there has not been a major accident in over 20 years. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this. The re-emergence of nuclear power today is founded on the present generation of nuclear reactors meeting the demands of extended service life, ensuring the cost competitiveness of nuclear power and matching enhanced safety requirements. Nuclear power plant engineers should be able to demonstrate such integrity and reliability of their system materials and components as to enable nuclear power plants to operate beyond their initial design life. Effective waste management is another challenge for sustainable nuclear energy today; more precisely, a solution is needed for the management of high-level and long-lived intermediate-level radioactive waste over the very long term. Most nuclear countries are currently gathering the data needed to assess the feasibility of a deep geological waste repository, including the prediction of the behaviour of materials over several thousands of years. The extended service life of nuclear power plants and the need for permanent disposal for nuclear waste are today's key issues in the nuclear industry. We focus here on the major role that corrosion plays in these two factors, and on the French approaches to these two issues. (authors)

Energy supply today and tomorrow, national and global

International Nuclear Information System (INIS)

Ott, G.

2003-01-01

A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

The surface analysis methods

International Nuclear Information System (INIS)

Deville, J.P.

1998-01-01

Nowadays, there are a lot of surfaces analysis methods, each having its specificity, its qualities, its constraints (for instance vacuum) and its limits. Expensive in time and in investment, these methods have to be used deliberately. This article appeals to non specialists. It gives some elements of choice according to the studied information, the sensitivity, the use constraints or the answer to a precise question. After having recalled the fundamental principles which govern these analysis methods, based on the interaction between radiations (ultraviolet, X) or particles (ions, electrons) with matter, two methods will be more particularly described: the Auger electron spectroscopy (AES) and x-rays photoemission spectroscopy (ESCA or XPS). Indeed, they are the most widespread methods in laboratories, the easier for use and probably the most productive for the analysis of surface of industrial materials or samples submitted to treatments in aggressive media.

STOCHASTIC METHODS IN RISK ANALYSIS

Directory of Open Access Journals (Sweden)

Vladimíra OSADSKÁ

2017-06-01

Full Text Available In this paper, we review basic stochastic methods which can be used to extend state-of-the-art deterministic analytical methods for risk analysis. We can conclude that the standard deterministic analytical methods highly depend on the practical experience and knowledge of the evaluator and therefore, the stochastic methods should be introduced. The new risk analysis methods should consider the uncertainties in input values. We present how large is the impact on the results of the analysis solving practical example of FMECA with uncertainties modelled using Monte Carlo sampling.

Fixing health care from the inside, today.

Science.gov (United States)

Spear, Steven J

2005-09-01

Today, you are about as safe in a U.S. hospital as you would be parachuting off a bridge or a building. But it doesn't have to be that way. Right now, some hospitals are making enormous short-term improvements, with no legislation or market reconfiguration and little or no capital investment. Instead of waiting for sweeping changes in market mechanisms, these institutions are taking an operations approach to patient care. In case after detailed case, the article describes how doctors, nurses, technicians, and managers are radically increasing the effectiveness of patient care and dramatically lowering its cost by applying the same capabilities in operations design and improvement that drive the famous Toyota Production System. They are removing ambiguity in the output, responsibilities, connections, and methods of their work processes. These changes-which can be done in the course of an ordinary workday, sometimes in a matter of hours-are designed to make the following crystal clear: Which patient gets which procedure (output); Who does which aspect of the job (responsibility); Exactly which signals are used to indicate that the work should begin (connection); and Precisely how each step is carried out (method). Equally important, managers are being transformed from rescuers who arrive with ready-made solutions into problem solvers who help colleagues learn the experimental method. Thus, these hospitals are breaking free of the work-around culture that routinely obscures the root causes of so many problems, creates so much waste, and leads to so many unnecessary deaths.

Alternative motor fuels today and tomorrow

Bensaid, B.

2004-01-01

Today, petroleum products account for 97% of the energy consumed in road transport. The purpose of replacing these products with alternative energies is to reduce oil dependence as well as greenhouse gas emissions. The high price of oil has promoted the use of 'conventional' alternative motor fuels (biofuels, LPG, NGV) and also renewed interest in syn-fuels (GTL, CTL, BTL) that have already given rise to industrial and pilot projects.

Comparison of nuclear analytical methods with competitive methods

International Nuclear Information System (INIS)

1987-10-01

The use of nuclear analytical techniques, especially neutron activation analysis, already have a 50 year old history. Today several sensitive and accurate, non-nuclear trace element analytical techniques are available and new methods are continuously developed. The IAEA is supporting the development of nuclear analytical laboratories in its Member States. In order to be able to advise the developing countries which methods to use in different applications, it is important to know the present status and development trends of nuclear analytical methods, what are their benefits, drawbacks and recommended fields of application, compared with other, non-nuclear techniques. In order to get an answer to these questions the IAEA convened this Advisory Group Meeting. This volume is the outcome of the presentations and discussions of the meeting. A separate abstract was prepared for each of the 21 papers. Refs, figs, tabs

Vaccination ecosystem health check: achieving impact today and sustainability for tomorrow.

Science.gov (United States)

Saadatian-Elahi, Mitra; Bloom, David; Plotkin, Stanley; Picot, Valentina; Louis, Jacques; Watson, Michael

2017-01-01

Vaccination is a complex ecosystem with several components that interact with one another and with the environment. Today's vaccine ecosystem is defined by the pursuit of polio eradication, the drive to get as many of the new vaccines to as many people as possible and the research and development against immunologically challenging diseases. Despite these successes, vaccine ecosystem is facing keys issues with regard to supply/distribution and cost/profitability asymmetry that risk slowing its global growth. The conference "Vaccination ecosystem health check: achieving impact today and sustainability for tomorrow" held in Annecy-France (January 19-21, 2015) took stock of the health of today's vaccination ecosystem and its ability to reliably and sustainably supply high-quality vaccines while investing in tomorrow's needed innovation. Small and decreasing numbers of suppliers/manufacturing facilities; paucity of research-driven companies; regulatory pressures; market uncertainties; political prioritization; anti-vaccine movements/complacency; and technological and programmatic issues were acknowledged as the major challenges that could weaken today's vaccination ecosystem. The expert panel discussed also drivers and barriers to a sustainable vaccination ecosystem; the metrics of a vaccination ecosystem; and what should be added, removed, increased, or reduced to maintain the health of the vaccination ecosystem.

New forecasting methodology indicates more disease and earlier mortality ahead for today's younger Americans.

Science.gov (United States)

Reither, Eric N; Olshansky, S Jay; Yang, Yang

2011-08-01

Traditional methods of projecting population health statistics, such as estimating future death rates, can give inaccurate results and lead to inferior or even poor policy decisions. A new "three-dimensional" method of forecasting vital health statistics is more accurate because it takes into account the delayed effects of the health risks being accumulated by today's younger generations. Applying this forecasting technique to the US obesity epidemic suggests that future death rates and health care expenditures could be far worse than currently anticipated. We suggest that public policy makers adopt this more robust forecasting tool and redouble efforts to develop and implement effective obesity-related prevention programs and interventions.

Energy financing in today's world - a banker's viewpoint

International Nuclear Information System (INIS)

Mackrell, Ian

1991-01-01

If the world runs on energy, the energy industry runs on finance. Supplying the industry's huge appetite for funds -on the scale and in the form required - has always posed a major challenge to the international banking community. But in some respects that challenge is greater today than it has ever been, not only because of the industry's escalating requirements but also because of the way bank's attitudes have been changing in the recent past. One reason for this is the rapidly evolving scene within the energy business in response to the harsher competitive conditions and the greater uncertainties of tomorrow. However, the other major factor is that banking itself has been undergoing significant change as a result of severe pressures and constraints, both internal and external. Some of the key global trends and issues affecting energy financing in today's world are considered here. (author)

Artificial insemination in pigs today.

Science.gov (United States)

Knox, R V

2016-01-01

Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms.

Knee arthrography today

International Nuclear Information System (INIS)

Otto, H.; Kallenberger, R.

1987-01-01

The role of knee arthrography today is demonstrated and technical problems are discussed. Among a lot of variants the position of the patient and the choice of contrast media play a great part concerning the result of the examination. Mild complications occur in 0.25% of the examinations, severe and live threatening complications are extremely rare. Diagnosis of meniscal lesions is most important for knee arthrography; arthroscopy and arthrography are complementary examinations and not mutually exclusive, they achieve combined an accuracy of 97-98%. In the same way arthrography is able to evaluate the condropathy of the femoro-tibial joint, whereas accuracy of arthroscopy in the diagnosis of patellar chondropathy is much higher. There is a great reliability of arthrography regarding the evaluation of lesions of the capsule, but accuracy in lesions of the cruciate ligaments is low. Arthrography is very suitable for evaluation of Baker-cysts, since indications for almost occuring internal derangement of the knee are even available. Knee arthrography is a complex and safe procedure with very less discomfort for the patient; it has a central position in the evaluation of lesions of the knee. (orig.) [de

Aromatics are the essential building blocks for some of the largest petrochemical products in today's use. To the vast majority they are consumed to produce intermediates for polymer products and, hence, contribute to our modern lifestyle. Their growth rates are expected to be in line with GDP growth in future. This contrasts the significantly lower growth rates of the primary sources for aromatics - fuel processing and steam cracking of naphtha fractions. A supply gap can be expected to open up in future for which creative solutions will be required. (orig.)

Seismic design and analysis methods

International Nuclear Information System (INIS)

Varpasuo, P.

1993-01-01

Seismic load is in many areas of the world the most important loading situation from the point of view of structural strength. Taking this into account it is understandable, that there has been a strong allocation of resources in the seismic analysis during the past ten years. In this study there are three areas of the center of gravity: (1) Random vibrations; (2) Soil-structure interaction and (3) The methods for determining structural response. The solution of random vibration problems is clarified with the aid of applications in this study and from the point of view of mathematical treatment and mathematical formulations it is deemed sufficient to give the relevant sources. In the soil-structure interaction analysis the focus has been the significance of frequency dependent impedance functions. As a result it was obtained, that the description of the soil with the aid of frequency dependent impedance functions decreases the structural response and it is thus always the preferred method when compared to more conservative analysis types. From the methods to determine the C structural response the following four were tested: (1) The time history method; (2) The complex frequency-response method; (3) Response spectrum method and (4) The equivalent static force method. The time history appeared to be the most accurate method and the complex frequency-response method did have the widest area of application. (orig.). (14 refs., 35 figs.)

Constructing an Intelligent Patent Network Analysis Method

Directory of Open Access Journals (Sweden)

Chao-Chan Wu

2012-11-01

Full Text Available Patent network analysis, an advanced method of patent analysis, is a useful tool for technology management. This method visually displays all the relationships among the patents and enables the analysts to intuitively comprehend the overview of a set of patents in the field of the technology being studied. Although patent network analysis possesses relative advantages different from traditional methods of patent analysis, it is subject to several crucial limitations. To overcome the drawbacks of the current method, this study proposes a novel patent analysis method, called the intelligent patent network analysis method, to make a visual network with great precision. Based on artificial intelligence techniques, the proposed method provides an automated procedure for searching patent documents, extracting patent keywords, and determining the weight of each patent keyword in order to generate a sophisticated visualization of the patent network. This study proposes a detailed procedure for generating an intelligent patent network that is helpful for improving the efficiency and quality of patent analysis. Furthermore, patents in the field of Carbon Nanotube Backlight Unit (CNT-BLU were analyzed to verify the utility of the proposed method.

Combination of radiological and nuclear medical imaging in animals: an overview about the today's possibilities

International Nuclear Information System (INIS)

Behe, M.; Keil, B.; Kiessling, A.; Heverhagen, J.T.; Alfke, H.; Boehm, I.; Gotthardt, M.

2007-01-01

Molecular imaging of small animals has made considerable progress in the last years. Various research fields are interested in imaging small animals due to the lower numbers of animals per experiment. This has advantages with respect to financial, ethical and research aspects. Non-invasive imaging allows examination of one animal several times during the same experiment. This makes it possible to follow a pathological process in the same animal over time. However, the radiological methods used such as magnetic resonance imaging or computed tomography as well as the nuclear medicine methods such as single photon emission computed tomography or positron emission tomography suffer from disadvantages. Molecular aspects are limited in the radiological methods while anatomical localization is difficult in nuclear medicine. The fusion of these methods leads to additional information. This review shows today's possibilities with their advantages as well as disadvantages. (orig.)

The surface analysis methods; Les methodes d`analyse des surfaces

Energy Technology Data Exchange (ETDEWEB)

Deville, J.P. [Institut de Physique et Chimie, 67 - Strasbourg (France)

1998-11-01

Nowadays, there are a lot of surfaces analysis methods, each having its specificity, its qualities, its constraints (for instance vacuum) and its limits. Expensive in time and in investment, these methods have to be used deliberately. This article appeals to non specialists. It gives some elements of choice according to the studied information, the sensitivity, the use constraints or the answer to a precise question. After having recalled the fundamental principles which govern these analysis methods, based on the interaction between radiations (ultraviolet, X) or particles (ions, electrons) with matter, two methods will be more particularly described: the Auger electron spectroscopy (AES) and x-rays photoemission spectroscopy (ESCA or XPS). Indeed, they are the most widespread methods in laboratories, the easier for use and probably the most productive for the analysis of surface of industrial materials or samples submitted to treatments in aggressive media.

The Use of Object-Oriented Analysis Methods in Surety Analysis

Energy Technology Data Exchange (ETDEWEB)

Craft, Richard L.; Funkhouser, Donald R.; Wyss, Gregory D.

1999-05-01

Object-oriented analysis methods have been used in the computer science arena for a number of years to model the behavior of computer-based systems. This report documents how such methods can be applied to surety analysis. By embodying the causality and behavior of a system in a common object-oriented analysis model, surety analysts can make the assumptions that underlie their models explicit and thus better communicate with system designers. Furthermore, given minor extensions to traditional object-oriented analysis methods, it is possible to automatically derive a wide variety of traditional risk and reliability analysis methods from a single common object model. Automatic model extraction helps ensure consistency among analyses and enables the surety analyst to examine a system from a wider variety of viewpoints in a shorter period of time. Thus it provides a deeper understanding of a system's behaviors and surety requirements. This report documents the underlying philosophy behind the common object model representation, the methods by which such common object models can be constructed, and the rules required to interrogate the common object model for derivation of traditional risk and reliability analysis models. The methodology is demonstrated in an extensive example problem.

Today's threat and tomorrow's reaction

International Nuclear Information System (INIS)

Moore, L.R.

2002-01-01

Full text: The events of September 11 have only confirmed our past nightmares and warnings to industries, agencies, and governments. The threat of even more significant catastrophic attacks, using nuclear materials, was just as real ten years ago, as it is today. In many cases, our vulnerability remains the same as years ago. There is a dire need for all organizations to agree upon threats and vulnerabilities, and to implement appropriate protections, for nuclear materials or other 'means' to achieve an event of mass destruction. All appropriate organizations (industries, agencies, and governments) should be able to define, assess, and recognize international threats and vulnerabilities in the same manner. In complimentary fashion, the organizations should be able to implement safeguards against this consistent generic threat. On an international scale the same threats, and most vulnerabilities, pose high risks to all of these organizations and societies. Indeed, in today's world, the vulnerabilities of one nation may clearly pose great risk to another nation. Once threats and vulnerabilities are consistently recognized, we can begin to approach their mitigation in a more 'universal' fashion by the application of internationally recognized and accepted security measures. The path to recognition of these security measures will require agreement on many diverse issues. However, once there is general agreement, we can then proceed to the acquisition of diverse national and international resources with which to implement the security measures 'universally' to eliminate 'weak-links' in the chain of nuclear materials, on a truly international scale. I would like to discuss: developing a internationally acceptable 'generic' statement of threat, vulnerability assessment process, and security measure; proposing this international statement of threat, vulnerability assessment process, and appropriate security measures to organizations (industries, agencies, and governments

"Children are from heaven" or how today children respect adults

Barbara Vogrinec

2007-06-01

Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

1976-01-01

The rapid development in recent years of energy dispersive x-ray fluorescence analysis has been based primarily on improvements in semiconductor detector x-ray spectrometers. However, the whole analysis system performance is critically dependent on the availability of optimum methods of excitation for the characteristic x rays in specimens. A number of analysis facilities based on various methods of excitation have been developed over the past few years. A discussion is given of the features of various excitation methods including charged particles, monochromatic photons, and broad-energy band photons. The effects of the excitation method on background and sensitivity are discussed from both theoretical and experimental viewpoints. Recent developments such as pulsed excitation and polarized photons are also discussed

The review of the modeling methods and numerical analysis software for nanotechnology in material science

differential equations can be used. In the cases when pairwise forces depend not only on distance between surfaces of particles, the development of special-purpose algorithms and software is required. The investigation at lower spatial level can be done with help of quantum chemistry packages. In the middle between microstructural and atomistic levels there was a gap corresponding to the scale 1...100 nm. At this level properties of material are considerably affected by size; this fact is proposed to be considered when defining nanostructure of constructional composite. Today there are a lot of achievements in development of modeling methods and software; however, there are still several problems to be solved. The system approach to the analysis of problem, followed by selection of proper modeling methods, algorithms and software tools, is the key for design of new efficient building materials.

CSM research: Methods and application studies

Knight, Norman F., Jr.

1989-01-01

Computational mechanics is that discipline of applied science and engineering devoted to the study of physical phenomena by means of computational methods based on mathematical modeling and simulation, utilizing digital computers. The discipline combines theoretical and applied mechanics, approximation theory, numerical analysis, and computer science. Computational mechanics has had a major impact on engineering analysis and design. When applied to structural mechanics, the discipline is referred to herein as computational structural mechanics. Complex structures being considered by NASA for the 1990's include composite primary aircraft structures and the space station. These structures will be much more difficult to analyze than today's structures and necessitate a major upgrade in computerized structural analysis technology. NASA has initiated a research activity in structural analysis called Computational Structural Mechanics (CSM). The broad objective of the CSM activity is to develop advanced structural analysis technology that will exploit modern and emerging computers, such as those with vector and/or parallel processing capabilities. Here, the current research directions for the Methods and Application Studies Team of the Langley CSM activity are described.

Crosscheck Principle in Pediatric Audiology Today: A 40-Year Perspective.

Science.gov (United States)

Hall, James W

2016-09-01

The crosscheck principle is just as important in pediatric audiology as it was when first described 40 years ago. That is, no auditory test result should be accepted and used in the diagnosis of hearing loss until it is confirmed or crosschecked by one or more independent measures. Exclusive reliance on only one or two tests, even objective auditory measures, may result in a auditory diagnosis that is not clear or perhaps incorrect. On the other hand, close and careful analysis of findings for a test battery consisting of objective procedures and behavioral tests whenever feasible usually leads to prompt and accurate diagnosis of auditory dysfunction. This paper provides a concise review of the crosscheck principle from its introduction to its clinical application today. The review concludes with a description of a modern test battery for pediatric hearing assessment that supplements traditional behavioral tests with a variety of independent objective procedures including aural immittance measures, otoacoustic emissions, and auditory evoked responses.

CERN Document Server

Vakilipourtakalou, Pourya

2016-01-01

Today computation is an inseparable part of scientific research. Specially in Particle Physics when there is a classification problem like discrimination of Signals from Backgrounds originating from the collisions of particles. On the other hand, Monte Carlo simulations can be used in order to generate a known data set of Signals and Backgrounds based on theoretical physics. The aim of Machine Learning is to train some algorithms on known data set and then apply these trained algorithms to the unknown data sets. However, the most common framework for data analysis in Particle Physics is ROOT. In order to use Machine Learning methods, a Toolkit for Multivariate Data Analysis (TMVA) has been added to ROOT. The major consideration in this report is the parallelization of some TMVA methods, specially Cross-Validation and BDT.

Investigation on method of elasto-plastic analysis for piping system (benchmark analysis)

International Nuclear Information System (INIS)

Kabaya, Takuro; Kojima, Nobuyuki; Arai, Masashi

2015-01-01

This paper provides method of an elasto-plastic analysis for practical seismic design of nuclear piping system. JSME started up the task to establish method of an elasto-plastic analysis for nuclear piping system. The benchmark analyses have been performed in the task to investigate on method of an elasto-plastic analysis. And our company has participated in the benchmark analyses. As a result, we have settled on the method which simulates the result of piping exciting test accurately. Therefore the recommended method of an elasto-plastic analysis is shown as follows; 1) An elasto-plastic analysis is composed of dynamic analysis of piping system modeled by using beam elements and static analysis of deformed elbow modeled by using shell elements. 2) Bi-linear is applied as an elasto-plastic property. Yield point is standardized yield point multiplied by 1.2 times, and second gradient is 1/100 young's modulus. Kinematic hardening is used as a hardening rule. 3) The fatigue life is evaluated on strain ranges obtained by elasto-plastic analysis, by using the rain flow method and the fatigue curve of previous studies.

1983-01-01

A complete census of all the biogas plants operating or under construction today in Italy has been carried out. This shows that more than 60 full-scale plants treating animal wastes are today in operation. Then there are several pilot and experimental plants built by the numerous Italian firms that design and sell anaerobic digesters and by various research groups of the universities and of state agencies. Some plants, among which some large-size ones, have been self-built by the farmers. The great amount of collected data allowed us to focus the main technological choices regarding materials, mixing and heating systems, technological cycles and to confront them with the performance of the plants and with the principal technical issues and the problems of management that can be found on large scale plants. Then the analysis of daily biogas production allowed us to determine real parameters of specific production for various kinds of animal wastes and animal farms. Other interesting data concern the main technological means used to transform the biogas into energy: in Italy, for the presence of Flat Industries that produce the TOTEM, the prevalent choice is toward cogeneration of electricity and heat. Anyway there are interesting examples of utilization of biogas for drying forages, for steam generation in cheese factories, and compressed, as a fuel for farm tractors and cars. A complete photographic documentation of all the plants enclosed in the census is also available. 3 refs., 1 fig., 23 tabs.

Speckle metrology in the nanoworld, as it is perceived today, and how it may affect industry

Science.gov (United States)

Pryputniewicz, Ryszard J.

2010-09-01

My memory goes back to my early collage studies that were almost entirely on the scale of "macroworld", as we practiced/perceived it some four decades ago. Since that time things have changed a lot constantly decreasing the scales of interest, at times at rather rapid pace, with monumental advances leading to the scales we work with today and plan for tomorrow. During that change/transition there were "meso" and "micro" developments characterized by changes in scales/sizes of things of interest. Today's scale of interest is "nano" and we are already not only working with "picotechnology", but are even reaching beyond while constantly "planning and projecting" the scales/worlds of the future. Advancement of any technology, especially new emerging ones as we witness/experience them today, is facilitated by the use of all available solution strategies. One of the emerging strategies that affect almost anything currently being developed and/or used, in the today's nanoworld, is based on recent advances of microelectromechanical systems (MEMS). Today MEMS affect almost everything we do from household appliances, via cars we drive and planes that whisk us from continent to continent, to spaceships used for search of/and exploration of other worlds. The modern microsensors are also used to explore for and produce petroleum products that are used in multitude of today's applications. To facilitate these advances a great majority of MEMS is used in the form of sensors. However development of MEMS in general and sensors in particular poses one of the greatest challenges in today's experimental mechanics. Among MEMS, the greatest contemporary interest is in the area of inertial sensors because they have numerous uses ranging from everyday applications to highly specialized ones, including many industrial platforms. As such they have tremendous potential to affect future of humanity. However, advances in MEMS, such as pressure and temperature sensors as well as gyroscopes and

Little is known about reproductive function in girls with youth-onset type 2 diabetes. To characterize girls with irregular menses, and effects of glycemic treatments on menses and sex steroids in the Treatment Options for Type 2 Diabetes in Youth (TODAY) study. Differences in demographic, metabolic, and hormonal characteristics between regular vs. irregular menses groups were tested; treatment group (metformin +/- rosiglitazone, metformin + lifestyle) effect on menses and sex steroids over time in the study was assessed. This is a secondary analysis of TODAY data. Multi-center study in an academic setting. TODAY girls not on hormonal contraception and those > 1-year post-menarche were included. Irregular menses was defined as irregular menses. Those with irregular vs. regular menses had higher body mass index (BMI) (p=0.001), AST (p=0.001), free androgen index (p=0.0003), total testosterone (p=0.01); and lower sex-hormone binding globulin (SHBG) (p=0.004) and estradiol (p=0.01). Differences remained after adjusting for BMI. There was no treatment group effect on menses or sex steroids at 12 or 24 months, and no association of sex steroids with measures of insulin sensitivity or secretion. Menstrual dysfunction is common in girls with recently diagnosed T2D and associated with alterations in sex steroids, SHBG, and AST, but not with alteration in insulin sensitivity or β-cell function, and did not improve with 2 years of anti-hyperglycemic treatment.

2016-01-01

Full Text Available The dimensionality reduction methods are algorithms mapping the set of data in subspaces derived from the original space, of fewer dimensions, that allow a description of the data at a lower cost. Due to their importance, they are widely used in processes associated with learning machine. This article presents a comparative analysis of PCA, PPCA and KPCA dimensionality reduction methods. A reconstruction experiment of worm-shape data was performed through structures of landmarks located in the body contour, with methods having different number of main components. The results showed that all methods can be seen as alternative processes. Nevertheless, thanks to the potential for analysis in the features space and the method for calculation of its preimage presented, KPCA offers a better method for recognition process and pattern extraction

Pathways to lean software development: An analysis of effective methods of change

Science.gov (United States)

Hanson, Richard D.

This qualitative Delphi study explored the challenges that exist in delivering software on time, within budget, and with the original scope identified. The literature review identified many attempts over the past several decades to reform the methods used to develop software. These attempts found that the classical waterfall method, which is firmly entrenched in American business today was to blame for this difficulty (Chatterjee, 2010). Each of these proponents of new methods sought to remove waste, lighten out the process, and implement lean principles in software development. Through this study, the experts evaluated the barriers to effective development principles and defined leadership qualities necessary to overcome these barriers. The barriers identified were issues of resistance to change, risk and reward issues, and management buy-in. Thirty experts in software development from several Fortune 500 companies across the United States explored each of these issues in detail. The conclusion reached by these experts was that visionary leadership is necessary to overcome these challenges.

Instrumental neutron activation analysis as a routine method for rock analysis

International Nuclear Information System (INIS)

Rosenberg, R.J.

1977-06-01

Instrumental neutron activation methods for the analysis of geological samples have been developed. Special emphasis has been laid on the improvement of sensitivity and accuracy in order to maximize tha quality of the analyses. Furthermore, the procedures have been automated as far as possible in order to minimize the cost of the analysis. A short review of the basic literature is given followed by a description of the principles of the method. All aspects concerning the sensitivity are discussed thoroughly in view of the analyst's possibility of influencing them. Experimentally determined detection limits for Na, Al, K, Ca, Sc, Cr, Ti, V, Mn, Fe, Ni, Co, Rb, Zr, Sb, Cs, Ba, La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Yb, Lu, Hf, Ta, Th and U are given. The errors of the method are discussed followed by actions taken to avoid them. The most significant error was caused by flux deviation, but this was avoided by building a rotating sample holder for rotating the samples during irradiation. A scheme for the INAA of 32 elements is proposed. The method has been automated as far as possible and an automatic γ-spectrometer and a computer program for the automatic calculation of the results are described. Furthermore, a completely automated uranium analyzer based on delayed neutron counting is described. The methods are discussed in view of their applicability to rock analysis. It is stated that the sensitivity varies considerably from element to element and instrumental activation analysis is an excellent method for the analysis of some specific elements like lanthanides, thorium and uranium but less so for many other elements. The accuracy is good varying from 2% to 10% for most elements. Instrumental activation analysis for most elements is rather an expensive method there being, however, a few exceptions. The most important of these is uranium. The analysis of uranium by delayed neutron counting is an inexpensive means for the analysis of large numbers of samples needed for

Quantitative analysis method for ship construction quality

Directory of Open Access Journals (Sweden)

FU Senzong

2017-03-01

Full Text Available The excellent performance of a ship is assured by the accurate evaluation of its construction quality. For a long time, research into the construction quality of ships has mainly focused on qualitative analysis due to a shortage of process data, which results from limited samples, varied process types and non-standardized processes. Aiming at predicting and controlling the influence of the construction process on the construction quality of ships, this article proposes a reliability quantitative analysis flow path for the ship construction process and fuzzy calculation method. Based on the process-quality factor model proposed by the Function-Oriented Quality Control (FOQC method, we combine fuzzy mathematics with the expert grading method to deduce formulations calculating the fuzzy process reliability of the ordinal connection model, series connection model and mixed connection model. The quantitative analysis method is applied in analyzing the process reliability of a ship's shaft gear box installation, which proves the applicability and effectiveness of the method. The analysis results can be a useful reference for setting key quality inspection points and optimizing key processes.

The quantitative analysis of myocardial SPECT images is a powerful tool to extract the highly specific radio tracer uptake in these studies. If compared to normal data bases, the uptake values can be calibrated on an individual basis. Doing so increases the reproducibility of the analysis substantially. Based on the development over the last three decades starting from planar scinitigraphy, this paper discusses the methods used today incorporating the changes due to tomographic image acquisitions. Finally, the limitations of these approaches as well as consequences from most recent hardware developments, commercial analysis packages and a wider view of the description of the left ventricle are discussed.

Tiptoeing to chromosome tips: facts, promises and perils of today's human telomere biology.

Science.gov (United States)

Fajkus, J; Simícková, M; Maláska, J

2002-04-29

The past decade has witnessed an explosion of knowledge concerning the structure and function of chromosome terminal structures-telomeres. Today's telomere research has advanced from a pure descriptive approach of DNA and protein components to an elementary understanding of telomere metabolism, and now to promising applications in medicine. These applications include 'passive' ones, among which the use of analysis of telomeres and telomerase (a cellular reverse transcriptase that synthesizes telomeres) for cancer diagnostics is the best known. The 'active' applications involve targeted downregulation or upregulation of telomere synthesis, either to mortalize immortal cancer cells, or to rejuvenate mortal somatic cells and tissues for cellular transplantations, respectively. This article reviews the basic data on structure and function of human telomeres and telomerase, as well as both passive and active applications of human telomere biology.

Accident Analysis and Barrier Function (AEB) Method. Manual for Incident Analysis

International Nuclear Information System (INIS)

Svenson, Ola

2000-02-01

The Accident Analysis and Barrier Function (AEB) Method models an accident or incident as a series of interactions between human and technical systems. In the sequence of human and technical errors leading to an accident there is, in principle, a possibility to arrest the development between each two successive errors. This can be done by a barrier function which, for example, can stop an operator from making an error. A barrier function can be performed by one or several barrier function systems. To illustrate, a mechanical system, a computer system or another operator can all perform a given barrier function to stop an operator from making an error. The barrier function analysis consists of analysis of suggested improvements, the effectiveness of the improvements, the costs of implementation, probability of implementation, the cost of maintaining the barrier function, the probability that maintenance will be kept up to standards and the generalizability of the suggested improvement. The AEB method is similar to the US method called HPES, but differs from that method in different ways. To exemplify, the AEB method has more emphasis on technical errors than HPES. In contrast to HPES that describes a series of events, the AEB method models only errors. This gives a more focused analysis making it well suited for checking other HPES-type accident analyses. However, the AEB method is a generic and stand-alone method that has been applied in other fields than nuclear power, such as, in traffic accident analyses

Inelastic analysis methods for piping systems

International Nuclear Information System (INIS)

Boyle, J.T.; Spence, J.

1980-01-01

The analysis of pipework systems which operate in an environment where local inelastic strains are evident is one of the most demanding problems facing the stress analyst in the nuclear field. The spatial complexity of even the most modest system makes a detailed analysis using finite element techniques beyond the scope of current computer technology. For this reason the emphasis has been on simplified methods. It is the aim of this paper to provide a reasonably complete, state-of-the-art review of inelastic pipework analysis methods and to attempt to highlight areas where reliable information is lacking and further work is needed.

Limitations of systemic accident analysis methods

Directory of Open Access Journals (Sweden)

Casandra Venera BALAN

2016-12-01

Full Text Available In terms of system theory, the description of complex accidents is not limited to the analysis of the sequence of events / individual conditions, but highlights nonlinear functional characteristics and frames human or technical performance in relation to normal functioning of the system, in safety conditions. Thus, the research of the system entities as a whole is no longer an abstraction of a concrete situation, but an exceeding of the theoretical limits set by analysis based on linear methods. Despite the issues outlined above, the hypothesis that there isn’t a complete method for accident analysis is supported by the nonlinearity of the considered function or restrictions, imposing a broad vision of the elements introduced in the analysis, so it can identify elements corresponding to nominal parameters or trigger factors.

2016-01-01

Enterprise models are created for documenting and communicating the structure and state of Business and Information Technologies elements of an enterprise. After models are completed, they are mainly used to support analysis. Model analysis is an activity typically based on human skills and due to the size and complexity of the models, this process can be complicated and omissions or miscalculations are very likely. This situation has fostered the research of automated analysis methods, for supporting analysts in enterprise analysis processes. By reviewing the literature, we found several analysis methods; nevertheless, they are based on specific situations and different metamodels; then, some analysis methods might not be applicable to all enterprise models. This paper presents the work of compilation (literature review), classification, structuring, and characterization of automated analysis methods for enterprise models, expressing them in a standardized modeling language. In addition, we have implemented the analysis methods in our modeling tool.

Lu Xifeng; Zhang Yixiong; Ai Honglei; Wang Xinjun; He Feng

2014-01-01

The simplified analysis method and the detailed analysis method were used for the fatigue analysis of the nozzle on the main piping. Because the structure of the oblique safety injection nozzle is complex and some more severe transients are subjected. The results obtained are more penalized and cannot be validate when the simplified analysis method used for the fatigue analysis. It will be little conservative when the detailed analysis method used, but it is more complex and time-consuming and boring labor. To reduce the conservatism and save time, the mixed analysis method which combining the simplified analysis method with the detailed analysis method is used for the fatigue analysis. The heat transfer parameters between the fluid and the structure which used for analysis were obtained by heat transfer property experiment. The results show that the mixed analysis which heat transfer property is considered can reduce the conservatism effectively, and the mixed analysis method is a more effective and practical method used for the fatigue analysis of the oblique safety injection nozzle.

Analysis of vignette method data in sociological research

Directory of Open Access Journals (Sweden)

Zh V Puzanova

2016-12-01

Full Text Available The article considers the vignette method as a projective technique that can be an alternative for the traditional methods in mass surveys. The authors present an example of the study of the social representations of an intelligent man with the vignette method: identify the meaning of the concept ‘social representations’ suggested by S. Moscovici, a scientist who introduced its conceptualization and empirical interpretation; and describe the structure of social representations which consists of a ‘core’ and a ‘periphery’ according to the theory of J.-C. Abric. The article shows the process of creating vignettes, choosing their number and conditions for the tool application. The main emphasis is made on the analysis of data obtained through the vignette method by calculating indices, discriminant analysis and logistic regression, and the explanation for the application of these three techniques is given. The authors describe the research procedure, the creation of the tool and the sample; compare the results of each method of analysis. Discriminant analysis and logistic regression data confirm each other, which is an important verification of the results of different methods of analysis.

EMA beamline at SIRIUS: extreme condition X-ray methods of analysis

Full text: The EMA beamline (Extreme condition X-ray Methods of Analysis) is one of the hard x-ray undulator beamlines within the first phase of the new synchrotron source in Brazil (Sirius project). This beamline is thought to make a difference where a high brilliance (high flux of up to 2 x 10 14 photons/sec with beam size down to 0.5 x 0.5 μm 2 ) is essential, which is the case for extreme pressures that require small focus and time-resolved that require high photon flux. With that in mind we propose the beamline to have two experimental hutches to cover most of the extreme condition techniques today employed at synchrotron laboratories worldwide. These two stations are thought to provide the general infrastructure for magnets and lasers experiments, which may evolve as new scientific problems appear. In addition to the hutches, support laboratories will be strongly linked and supportive to the experiments at the beamline, covering high pressure instrumentations using diamond anvil cells and pump-and-probe requirements for ultrafast and high power lasers. Along these lines, we will describe the following techniques covered at this beamline: magnetic spectroscopy (XMCD) and scattering (XRMS) under high pressure and very low temperature in order to fully probe both ferromagnetic and antiferromagnetic materials and the dependence with pressure; extreme pressure and temperature XRD and XAS experiments using very small diamond culet anvils and high power lasers.

Full Text Available Audit sampling involves the application of audit procedures to less than 100% of items within an account balance or class of transactions. Our article aims to study audit sampling in audit of financial statements. As an audit technique largely used, in both its statistical and nonstatistical form, the method is very important for auditors. It should be applied correctly for a fair view of financial statements, to satisfy the needs of all financial users. In order to be applied correctly the method must be understood by all its users and mainly by auditors. Otherwise the risk of not applying it correctly would cause loose of reputation and discredit, litigations and even prison. Since there is not a unitary practice and methodology for applying the technique, the risk of incorrectly applying it is pretty high. The SWOT analysis is a technique used that shows the advantages, disadvantages, threats and opportunities. We applied SWOT analysis in studying the sampling method, from the perspective of three players: the audit company, the audited entity and users of financial statements. The study shows that by applying the sampling method the audit company and the audited entity both save time, effort and money. The disadvantages of the method are difficulty in applying and understanding its insight. Being largely used as an audit method and being a factor of a correct audit opinion, the sampling method’s advantages, disadvantages, threats and opportunities must be understood by auditors.

The aim of this study is to determine which health resorts existed in 1897 in Istria, Carinthia and Styria region, how many of them are still in use today and how the spas and their offer were represented in the past and how they are represented today. The study is based on the textbook Balneotherapie II (Bibliothek des Arztes 1900) by prof. dr. Julius Glax. The second source of our study is based on the currently available presentation of the health resorts from the internet. The textbook Balneotherapie was intended for the post graduate education of physicians and general practitioners, so they could advise the patient on further treatment in an appropriate health resort. In the chapter Balneographie the author represented 1200 health resorts all over the world. From the book we have chosen the following regions: Istria, Carinthia and Styria which used to be three parts of the Austro-Hungarian Empire. Today they are divided in to three neighboring states: Croatia (Istria), Slovenia (Istria, Carinthia, Styria) and Austria (Carinthia, Styria). Within these regions Glax presented 22 health resorts, 19 of them are still working today. Barbarabad/Barbara bath (Carinthia, Austria) does not exist either as a resort or as a city. Rimske toplice (Römerbad/Roman baths) and Rimski vrelec (Römerquelle/ Roman springs) in Styria region do not function as health resorts any more. Nowadays we make a difference between spa and health resorts. Spa resorts offer numerous forms of recreation for better well being. Health resorts offer health services, as well as neglected, but various forms of alternative treatments and recreation. Each spa and health resort is represented in brochures and on the World Wide Web individually. Tradition is usually not mentioned, it is neglected but the exception is Opatija (Abbazia) which past is usually presented in the brochures. The museum of medical tourism was opened in November 2007 in Opatija where you can admire the development of Opatija

Lee, Uk Jae; Jung, Yun Song; Kim, Hee Reyoung [UNIST, Ulsan (Korea, Republic of)

2016-05-15

When the sample of several mixed radioactive nuclides is measured, it is difficult to divide each nuclide due to the overlapping of spectrums. For this reason, simple mathematical analysis method for spectrum analysis of the mixed beta ray source has been studied. However, existing research was in need of more accurate spectral analysis method as it has a problem of accuracy. The study will describe the contents of the separation methods of the mixed beta ray source through the analysis of the beta spectrum slope based on the curve fitting to resolve the existing problem. The fitting methods including It was understood that sum of sine fitting method was the best one of such proposed methods as Fourier, polynomial, Gaussian and sum of sine to obtain equation for distribution of mixed beta spectrum. It was shown to be the most appropriate for the analysis of the spectrum with various ratios of mixed nuclides. It was thought that this method could be applied to rapid spectrum analysis of the mixed beta ray source.

Karl Marx and the Study of Media and Culture Today

Directory of Open Access Journals (Sweden)

Christian Fuchs

2014-02-01

Full Text Available The task of this paper discusses the role of Marx in analysing media, communica-tion and culture today. An analysis of three contemporary Cultural Studies works – Lawrence Grossberg’s monograph Cultural Studies in the Future Tense, John Hartley’s monograph Digital Futures for Cultural and Media Studies and Paul Smith’s edited volume The Renewal of Cultural Studies – shows that there is an agreement that the economy needs to be taken more into account by Cultural Studies, but disagreement on which approach should be taken and what the role of Karl Marx’s works shall be. The paper argues that Marx’s labour theory of value is especially important for critically analysing the media, culture and communica-tion. Labour is still a blind spot of the study of culture and the media, although this situation is slowly improving. It is maintained that the turn away from Marx in Cultural and Media Studies was a profound mistake that should be reverted. Only an engagement with Marx can make Cultural and Media Studies topical, politically relevant, practical and critical, in the current times of global crisis and resurgent critique.

Eurycoma longifolia jack (Tongkat Ali, Genus: Eurycoma; Family, Simaroubaceae) is one of the most popular tropical herbal plants. The plant contains a series of quassinoids, which are mainly responsible for its bitter taste. The plant extract, especially roots, are exclusively used (traditionally) for enhancing testosterone levels in men. The roots also have been used in indigenous traditional medicines for its unique anti-malarial, anti-pyretic, antiulcer, cytotoxic and aphrodisiac properties. As part of an on-going research on the bioactive compound of Eurycoma longifolia and evaluation for an optimized analysis method and parameter that influence in LC-MS analysis were carried out. Identification of the bioactive compounds was based on comparison of calculated retention time and mass spectral data with literature values. Examination of the Eurycoma longifolia sample showed some variations and differences in terms of parameters in LC-MS. However, combined method using methanol as the solvent with injection volume 1.0 μL and analysis in ultra scan mode and acetic acid as acidic modifier is the optimum method for LCMS analysis of Eurycoma longifolia because it successfully detected the optimum mass of compounds with good resolution and perfectly separated within a short analysis time.

Multivariate meta-analysis of genetic association studies and genome-wide association studies has received a remarkable attention as it improves the precision of the analysis. Here, we review, summarize and present in a unified framework methods for multivariate meta-analysis of genetic association studies and genome-wide association studies. Starting with the statistical methods used for robust analysis and genetic model selection, we present in brief univariate methods for meta-analysis and we then scrutinize multivariate methodologies. Multivariate models of meta-analysis for a single gene-disease association studies, including models for haplotype association studies, multiple linked polymorphisms and multiple outcomes are discussed. The popular Mendelian randomization approach and special cases of meta-analysis addressing issues such as the assumption of the mode of inheritance, deviation from Hardy-Weinberg Equilibrium and gene-environment interactions are also presented. All available methods are enriched with practical applications and methodologies that could be developed in the future are discussed. Links for all available software implementing multivariate meta-analysis methods are also provided.

BEPU methods and combining of uncertainties

Prosek, A.; Mavko, B.

2004-01-01

After approval of the revised rule on the acceptance of emergency core cooling system (ECCS) performance in 1988 there has been significant interest in the development of codes and methodologies for best-estimate loss-of-coolant accident (LOCAs) analyses. The Code Scaling, Applicability and Uncertainty (CSAU) evaluation method was developed and demonstrated for large-break (LB) LOCA in a pressurized water reactor. Later several new best estimate plus uncertainty methods (BEPUs) were developed in the world. The purpose of the paper is to identify and compare the statistical approaches of BEPU methods and present their important plant and licensing applications. The study showed that uncertainty analysis with random sampling of input parameters and the use of order statistics for desired tolerance limits of output parameters is today commonly accepted approach. The existing BEPU methods seems mature enough while the future research may be focused on the codes with internal assessment of uncertainty. (author)

Energy And Environment in Urban Regeneration. Studies for a Method of Analysis of Urban Periphery

Directory of Open Access Journals (Sweden)

Paolo De Pascali

2014-05-01

Full Text Available Despite planning of urban regeneration has been theorized from several decades, today activating concrete programs encounters major difficulties. Moreover, the structural nature of economic crisis and the operators tendency to maintaining obsolete models of urban transformation certainly do not help to overcome the stalemate.The article argues, however, that this framework appears to evolve under the influence of some external factors that bring to the fore the importance of the energy - environmental components in the renewal of the existing city.This address, focused on the concept of urban environment, seems to identify new principles of economic environmental sustainability of the city that converge towards social models of smart community and urban models of smart city.The article then describes the research in progress regarding an operative method to define explicit and replicable bases of the urban environment concept to be considered in plans of urban renewal. Main fields of observation and measurement are “urban comfort” and “anthropogenic load (pollution”. An experimental application of the analysis is developed on the eastern area of Rome. Finally, the paper offers specific lines for the research development.

A fully digitalized reactor protection system, which is called the IDiPS-RPS, was developed through the KNICS project. The IDiPS-RPS has four redundant and separated channels. Each channel is mainly composed of a group of bistable processors which redundantly compare process variables with their corresponding setpoints and a group of coincidence processors that generate a final trip signal when a trip condition is satisfied. Each channel also contains a test processor called the ATIP and a display and command processor called the COM. All the functions were implemented in software. During the development of the safety software, various software safety analysis methods were applied, in parallel to the verification and validation (V and V) activities, along the software development life cycle. The software safety analysis methods employed were the software hazard and operability (Software HAZOP) study, the software fault tree analysis (Software FTA), and the software failure modes and effects analysis (Software FMEA)

Advanced analysis methods in particle physics

Energy Technology Data Exchange (ETDEWEB)

Bhat, Pushpalatha C.; /Fermilab

2010-10-01

Each generation of high energy physics experiments is grander in scale than the previous - more powerful, more complex and more demanding in terms of data handling and analysis. The spectacular performance of the Tevatron and the beginning of operations of the Large Hadron Collider, have placed us at the threshold of a new era in particle physics. The discovery of the Higgs boson or another agent of electroweak symmetry breaking and evidence of new physics may be just around the corner. The greatest challenge in these pursuits is to extract the extremely rare signals, if any, from huge backgrounds arising from known physics processes. The use of advanced analysis techniques is crucial in achieving this goal. In this review, I discuss the concepts of optimal analysis, some important advanced analysis methods and a few examples. The judicious use of these advanced methods should enable new discoveries and produce results with better precision, robustness and clarity.

Spectroscopic chemical analysis methods and apparatus are disclosed which employ deep ultraviolet (e.g. in the 200 nm to 300 nm spectral range) electron beam pumped wide bandgap semiconductor lasers, incoherent wide bandgap semiconductor light emitting devices, and hollow cathode metal ion lasers to perform non-contact, non-invasive detection of unknown chemical analytes. These deep ultraviolet sources enable dramatic size, weight and power consumption reductions of chemical analysis instruments. In some embodiments, Raman spectroscopic detection methods and apparatus use ultra-narrow-band angle tuning filters, acousto-optic tuning filters, and temperature tuned filters to enable ultra-miniature analyzers for chemical identification. In some embodiments Raman analysis is conducted along with photoluminescence spectroscopy (i.e. fluorescence and/or phosphorescence spectroscopy) to provide high levels of sensitivity and specificity in the same instrument.

This study examined parental factors associated with outcomes of youth in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial. Of 699 youth with type 2 diabetes in the TODAY cohort, 623 (89.1%) had a parent participate and provide data at baseline, including weight, HbA1c, blood pressure, symptoms of depression, binge eating (BE), and medical history. Youth were followed 2-6.5 years. Data were analyzed using regression models and survival curve methods. Parental diabetes (43.6% of parents) was associated with higher baseline HbA1c (P parent, P = 0.0002). Parental hypertension (40.6% of parents) was associated with hypertension in youth during TODAY (40.4% vs. 27.4% of youth with and without parental hypertension had hypertension, P = 0.0008) and with higher youth baseline BMI z scores (P = 0.0038). Parents had a mean baseline BMI of 33.6 kg/m(2). Parental obesity (BMI >30 kg/m(2)) was associated with higher baseline BMI z scores in the youth (P parents (20.6% of parents) were related to youth depressive symptoms at baseline only (P = 0.0430); subclinical BE in parents was related to the presence of subclinical BE (P = 0.0354) and depressive symptoms (P = 0.0326) in youth throughout the study period. Parental diabetes and hypertension were associated with lack of glycemic control, hypertension, and higher BMI z scores in youth. Further research is needed to better understand and address parental biological and behavioral factors to improve youth health outcomes. © 2015 by the American Diabetes Association.

Smith, Derek R; Watson, Roger

2016-11-01

A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Discussion paper. Published literature and relevant websites. The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be 'does it have a Twitter and/or Facebook site, or a blog (or all three)'; and 'does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?' Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication). © 2016 John Wiley & Sons Ltd.

Moulin, D.

1987-01-01

This report represents an attempt to review the mechanical analysis methods reported in the literature to account for the specific behaviour that we call buckling under strain. In this report, this expression covers all buckling mechanisms in which the strains imposed play a role, whether they act alone (as in simple buckling under controlled strain), or whether they act with other loadings (primary loading, such as pressure, for example). Attention is focused on the practical problems relevant to LMFBR reactors. The components concerned are distinguished by their high slenderness ratios and by rather high thermal levels, both constant and variable with time. Conventional static buckling analysis methods are not always appropriate for the consideration of buckling under strain. New methods must therefore be developed in certain cases. It is also hoped that this review will facilitate the coding of these analytical methods to aid the constructor in his design task and to identify the areas which merit further investigation

Evaluation and presentation of analysis methods for reception analysis in reprocessing

International Nuclear Information System (INIS)

Mainka, E.

1985-01-01

The fissile material content in the dissolving or balancing tank of a reprocessing plant has special significance in nuclear fuel balancing. This is the first opportunity for destructive analysis of the fuel content of the material after burn-up of fuel elements in the reactor. In the current state-of-the-art, all balancing methods are based directly or indirectly on data obtained by chemical analysis. The following methods are evaluated: Mass-spectroscopic isotope dilution analysis, X-ray fluorescence spectroscopy, Isotopic correlation, Gamma absorptiometry, Redox titration, Emission spectroscopy after plasma excitation, Alpha spectroscopy, and Laser Raman spectroscopy

Alternative methods for the seismic analysis of piping systems

International Nuclear Information System (INIS)

Anon.

1993-01-01

This document is a review of 12 methods and criteria for the seismic analysis of piping systems. Each of the twelve chapters in this document cover the important technical aspects of a given method. The technical aspects presented are those the Subcommittee on Dynamic Stress Criteria believe important to the application of the method, and should not be considered as a positive or negative endorsement for any of the methods. There are many variables in an analysis of a piping system that can influence the selection of the analysis method and criteria to be applied. These variable include system configuration, technical issues, precedent, licensing considerations, and regulatory acceptance. They must all be considered in selecting the appropriate seismic analysis method and criteria. This is relevant for nuclear power plants

An introduction to USITC enterprise analysis

Energy Technology Data Exchange (ETDEWEB)

Ostic, J.K.

1997-10-01

The United States Integrated Textile Complex (USITC) consists of fiber, textile, apparel, and retail firms who manufacture and distribute natural and synthetic fiber products. In today`s competitive global economy, USITC companies who team together to form supply chains require relationships which promote responsiveness to consumer demand, encourage business partnerships, and make effective use of resources. These supply chains, or pipelines, are being analyzed to improve time and cost performance. Enterprise analysis is the application of analysis methods and simulation tools to predict integrated performance of these pipelines. Through the use of scenario analysis, various alternatives in pipeline coordination and configuration can be assessed. Simply put, the end result is to design the pipeline so that the product the customer demands is delivered, in the right place, at the right time. In September 1996, industrial participants of the Demand Activated Manufacturing Architecture (DAMA) project completed the Phase 1 pipeline analysis study. The analysis identified opportunities to improve productivity and efficiency among five supply chain members, and proposed a generic modeling architecture and methodology that, if implemented, would identify actions necessary to improve supply-chain coordination among its members. The architecture and methodology are being pursued during the Phase 2 analysis, which is scheduled to be completed by the end of FY 1997. The goal of the Phase 2 analysis is to propose actionable recommendations to supply-chain members leading to a reduction of pipeline lead-time by 50%.

Religious Renaissance in China Today

Directory of Open Access Journals (Sweden)

Richard Madsen

2011-01-01

Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

Meshless methods in biomechanics bone tissue remodelling analysis

CERN Document Server

Belinha, Jorge

2014-01-01

This book presents the complete formulation of a new advanced discretization meshless technique: the Natural Neighbour Radial Point Interpolation Method (NNRPIM). In addition, two of the most popular meshless methods, the EFGM and the RPIM, are fully presented. Being a truly meshless method, the major advantages of the NNRPIM over the FEM, and other meshless methods, are the remeshing flexibility and the higher accuracy of the obtained variable field. Using the natural neighbour concept, the NNRPIM permits to determine organically the influence-domain, resembling the cellulae natural behaviour. This innovation permits the analysis of convex boundaries and extremely irregular meshes, which is an advantage in the biomechanical analysis, with no extra computational effort associated.   This volume shows how to extend the NNRPIM to the bone tissue remodelling analysis, expecting to contribute with new numerical tools and strategies in order to permit a more efficient numerical biomechanical analysis.

Cask crush pad analysis using detailed and simplified analysis methods

International Nuclear Information System (INIS)

Uldrich, E.D.; Hawkes, B.D.

1997-01-01

A crush pad has been designed and analyzed to absorb the kinetic energy of a hypothetically dropped spent nuclear fuel shipping cask into a 44-ft. deep cask unloading pool at the Fluorinel and Storage Facility (FAST). This facility, located at the Idaho Chemical Processing Plant (ICPP) at the Idaho national Engineering and Environmental Laboratory (INEEL), is a US Department of Energy site. The basis for this study is an analysis by Uldrich and Hawkes. The purpose of this analysis was to evaluate various hypothetical cask drop orientations to ensure that the crush pad design was adequate and the cask deceleration at impact was less than 100 g. It is demonstrated herein that a large spent fuel shipping cask, when dropped onto a foam crush pad, can be analyzed by either hand methods or by sophisticated dynamic finite element analysis using computer codes such as ABAQUS. Results from the two methods are compared to evaluate accuracy of the simplified hand analysis approach

Introduction to the Special Issue on Advancing Methods for Analyzing Dialect Variation.

Science.gov (United States)

Clopper, Cynthia G

2017-07-01

Documenting and analyzing dialect variation is traditionally the domain of dialectology and sociolinguistics. However, modern approaches to acoustic analysis of dialect variation have their roots in Peterson and Barney's [(1952). J. Acoust. Soc. Am. 24, 175-184] foundational work on the acoustic analysis of vowels that was published in the Journal of the Acoustical Society of America (JASA) over 6 decades ago. Although Peterson and Barney (1952) were not primarily concerned with dialect variation, their methods laid the groundwork for the acoustic methods that are still used by scholars today to analyze vowel variation within and across languages. In more recent decades, a number of methodological advances in the study of vowel variation have been published in JASA, including work on acoustic vowel overlap and vowel normalization. The goal of this special issue was to honor that tradition by bringing together a set of papers describing the application of emerging acoustic, articulatory, and computational methods to the analysis of dialect variation in vowels and beyond.

Nawaz, Ather

2012-01-01

This study investigates how the choice of analysis method for card sorting studies affects the suggested information structure for websites. In the card sorting technique, a variety of methods are used to analyse the resulting data. The analysis of card sorting data helps user experience (UX......) designers to discover the patterns in how users make classifications and thus to develop an optimal, user-centred website structure. During analysis, the recurrence of patterns of classification between users influences the resulting website structure. However, the algorithm used in the analysis influences...... the recurrent patterns found and thus has consequences for the resulting website design. This paper draws an attention to the choice of card sorting analysis and techniques and shows how it impacts the results. The research focuses on how the same data for card sorting can lead to different website structures...

Schmid, E.

1987-03-01

Today important chemical substances like proteins can be produced easily and in large amounts. The primary structure of proteins can be analysed automatically, however the procedure can take some months of time. A novel method, fast atom bombardment mass spectrometry (FAB-MS) in combination with enzymatic degradation not only decreases the analysis time, but gives also additional information about the primary structure. Especially for the verification of protein structures - which is important for recombinant proteins - FAB-MS is a very useful method. 40 refs., 56 figs. (P.W.)

2017-08-01

Background For a 2- to 6-year period, interventionists for the TODAY (Treatment Options for type 2 Diabetes in Adolescents and Youth) randomized clinical trial delivered a family-based, behavioral weight-loss program (the TODAY Lifestyle Program) to 234 youth with type 2 diabetes. Interventionists held at least a bachelor's degree in psychology, social work, education, or health-related field and had experience working with children and families, especially from diverse ethnic and socioeconomic backgrounds. This article describes the administrative and organizational structure of the lifestyle program and how the structure facilitated collaboration among study leadership and lifestyle interventionists on the tailoring of the program to best suit the needs of the trial's diverse patient population. Methods During the pilot phase and throughout the duration of the trial, the interventionists' experiences in delivering the intervention were collected in a variety of ways including membership on study committees, survey responses, session audio recordings, and feedback during in-person trainings. Results The experiences of interventionists conveyed to study leadership through these channels resulted in decisions to tailor the lifestyle intervention's delivery location and ways to supplement the standardized educational materials to better address the needs of a diverse patient population. Conclusion The methods used within the TODAY study to encourage and utilize interventionists' experiences while implementing the lifestyle program may be useful to the design of future multi-site, clinical trials seeking to tailor behavioral interventions in a standardized, and culturally and developmentally sensitive manner.

Recent Advances in the Method of Forces: Integrated Force Method of Structural Analysis

Science.gov (United States)

Patnaik, Surya N.; Coroneos, Rula M.; Hopkins, Dale A.

1998-01-01

Stress that can be induced in an elastic continuum can be determined directly through the simultaneous application of the equilibrium equations and the compatibility conditions. In the literature, this direct stress formulation is referred to as the integrated force method. This method, which uses forces as the primary unknowns, complements the popular equilibrium-based stiffness method, which considers displacements as the unknowns. The integrated force method produces accurate stress, displacement, and frequency results even for modest finite element models. This version of the force method should be developed as an alternative to the stiffness method because the latter method, which has been researched for the past several decades, may have entered its developmental plateau. Stress plays a primary role in the development of aerospace and other products, and its analysis is difficult. Therefore, it is advisable to use both methods to calculate stress and eliminate errors through comparison. This paper examines the role of the integrated force method in analysis, animation and design.

Methods of quantitative analysis of nuclear energy hazards

Papp, R.; Caldarola, L.; Helm, F.; Jansen, P.; McGrath, P.; Weber, G.

1975-03-01

Risk can be defined as the sum of all possible damage types weighted with their associated cumulative probability distributions of occurrence. Risk defined in this manner is not very suitable for comparison purposes. In order to be able to synthetically express the risk by means of a single parameter, two problems must be solved: 1) For each damage type an average value must be calculated which accounts not only for the occurence probability distribution but also for the degree and importance of the damage to human society. 2) The total average value (the risk) must be calculated by weighting each average damage type with a corresponding second importance function which represents the importance and acceptability of the particular damage type to human society. Here it must be pointed out that the above mentioned problems are directly connected to the problem of 'risk acceptance', which will be as well discussed as the risk associated with the entire nuclear fuel cycle. Finally, recommendations for further research work are given in section V which are thought to be needed in order to render these methods in the near future more generally applicable and accepted than they are today.

Today computers play an important role in the development of complex mechanical systems, such as cars, railway vehicles or machines. Efficient simulation of these systems is only possible when based on methods that explore the strong link between numerics and computational mechanics. This book gives insight into modern techniques of numerical mathematics in the light of an interesting field of applications: multibody dynamics. The important interaction between modeling and solution techniques is demonstrated by using a simplified multibody model of a truck. Different versions of this mechanical model illustrate all key concepts in static and dynamic analysis as well as in parameter identification. The book focuses in particular on constrained mechanical systems. Their formulation in terms of differential-algebraic equations is the backbone of nearly all chapters. The book is written for students and teachers in numerical analysis and mechanical engineering as well as for engineers in industrial research labor...

A comparison of analysis methods to estimate contingency strength.

Science.gov (United States)

Lloyd, Blair P; Staubitz, Johanna L; Tapp, Jon T

2018-05-09

To date, several data analysis methods have been used to estimate contingency strength, yet few studies have compared these methods directly. To compare the relative precision and sensitivity of four analysis methods (i.e., exhaustive event-based, nonexhaustive event-based, concurrent interval, concurrent+lag interval), we applied all methods to a simulated data set in which several response-dependent and response-independent schedules of reinforcement were programmed. We evaluated the degree to which contingency strength estimates produced from each method (a) corresponded with expected values for response-dependent schedules and (b) showed sensitivity to parametric manipulations of response-independent reinforcement. Results indicated both event-based methods produced contingency strength estimates that aligned with expected values for response-dependent schedules, but differed in sensitivity to response-independent reinforcement. The precision of interval-based methods varied by analysis method (concurrent vs. concurrent+lag) and schedule type (continuous vs. partial), and showed similar sensitivities to response-independent reinforcement. Recommendations and considerations for measuring contingencies are identified. © 2018 Society for the Experimental Analysis of Behavior.

Application of status uncertainty analysis methods for AP1000 LBLOCA calculation

International Nuclear Information System (INIS)

Zhang Shunxiang; Liang Guoxing

2012-01-01

Parameter uncertainty analysis is developed by using the reasonable method to establish the response relations between input parameter uncertainties and output uncertainties. The application of the parameter uncertainty analysis makes the simulation of plant state more accuracy and improves the plant economy with reasonable security assurance. The AP1000 LBLOCA was analyzed in this paper and the results indicate that the random sampling statistical analysis method, sensitivity analysis numerical method and traditional error propagation analysis method can provide quite large peak cladding temperature (PCT) safety margin, which is much helpful for choosing suitable uncertainty analysis method to improve the plant economy. Additionally, the random sampling statistical analysis method applying mathematical statistics theory makes the largest safety margin due to the reducing of the conservation. Comparing with the traditional conservative bounding parameter analysis method, the random sampling method can provide the PCT margin of 100 K, while the other two methods can only provide 50-60 K.

Comparability of river suspended-sediment sampling and laboratory analysis methods

Science.gov (United States)

Groten, Joel T.; Johnson, Gregory D.

2018-03-06

Accurate measurements of suspended sediment, a leading water-quality impairment in many Minnesota rivers, are important for managing and protecting water resources; however, water-quality standards for suspended sediment in Minnesota are based on grab field sampling and total suspended solids (TSS) laboratory analysis methods that have underrepresented concentrations of suspended sediment in rivers compared to U.S. Geological Survey equal-width-increment or equal-discharge-increment (EWDI) field sampling and suspended sediment concentration (SSC) laboratory analysis methods. Because of this underrepresentation, the U.S. Geological Survey, in collaboration with the Minnesota Pollution Control Agency, collected concurrent grab and EWDI samples at eight sites to compare results obtained using different combinations of field sampling and laboratory analysis methods.Study results determined that grab field sampling and TSS laboratory analysis results were biased substantially low compared to EWDI sampling and SSC laboratory analysis results, respectively. Differences in both field sampling and laboratory analysis methods caused grab and TSS methods to be biased substantially low. The difference in laboratory analysis methods was slightly greater than field sampling methods.Sand-sized particles had a strong effect on the comparability of the field sampling and laboratory analysis methods. These results indicated that grab field sampling and TSS laboratory analysis methods fail to capture most of the sand being transported by the stream. The results indicate there is less of a difference among samples collected with grab field sampling and analyzed for TSS and concentration of fines in SSC. Even though differences are present, the presence of strong correlations between SSC and TSS concentrations provides the opportunity to develop site specific relations to address transport processes not captured by grab field sampling and TSS laboratory analysis methods.

Safety relief valve alternate analysis method

International Nuclear Information System (INIS)

Adams, R.H.; Javid, A.; Khatua, T.P.

1981-01-01

An experimental test program was started in the United States in 1976 to define and quantify Safety Relief Valve (SRV) phenomena in General Electric Mark I Suppression Chambers. The testing considered several discharged devices and was used to correlate SRV load prediction models. The program was funded by utilities with Mark I containments and has resulted in a detailed SRV load definition as a portion of the Mark I containment program Load Definition Report (LDR). The (USNRC) has reviewed and approved the LDR SRV load definition. In addition, the USNRC has permitted calibration of structural models used for predicting torus response to SRV loads. Model calibration is subject to confirmatory in-plant testing. The SRV methodology given in the LDR requires that transient dynamic pressures be applied to a torus structural model that includes a fluid added mass matrix. Preliminary evaluations of torus response have indicated order of magnitude conservatisms, with respect to test results, which could result in unrealistic containment modifications. In addition, structural response trends observed in full-scale tests between cold pipe, first valve actuation and hot pipe, subsequent valve actuation conditions have not been duplicated using current analysis methods. It was suggested by others that an energy approach using current fluid models be utilized to define loads. An alternate SRV analysis method is defined to correct suppression chamber structural response to a level that permits economical but conservative design. Simple analogs are developed for the purpose of correcting the analytical response obtained from LDR analysis methods. Analogs evaluated considered forced vibration and free vibration structural response. The corrected response correlated well with in-plant test response. The correlation of the analytical model at test conditions permits application of the alternate analysis method at design conditions. (orig./HP)

Analysis and study on core power capability with margin method

International Nuclear Information System (INIS)

Liu Tongxian; Wu Lei; Yu Yingrui; Zhou Jinman

2015-01-01

Core power capability analysis focuses on the power distribution control of reactor within the given mode of operation, for the purpose of defining the allowed normal operating space so that Condition Ⅰ maneuvering flexibility is maintained and Condition Ⅱ occurrences are adequately protected by the reactor protection system. For the traditional core power capability analysis methods, such as synthesis method or advanced three dimension method, usually calculate the key safety parameters of the power distribution, and then verify that these parameters meet the design criteria. For PWR with on-line power distribution monitoring system, core power capability analysis calculates the most power level which just meets the design criteria. On the base of 3D FAC method of Westinghouse, the calculation model of core power capability analysis with margin method is introduced to provide reference for engineers. The core power capability analysis of specific burnup of Sanmen NPP is performed with the margin method. The results demonstrate the rationality of the margin method. The calculation model of the margin method not only helps engineers to master the core power capability analysis for AP1000, but also provides reference for engineers for core power capability analysis of other PWR with on-line power distribution monitoring system.

Gunar, O V; Sakhno, N G

2015-12-30

The total uncertainty of quantitative microbiological methods, used in pharmaceutical analysis, consists of several components. The analysis of the most important sources of the quantitative microbiological methods variability demonstrated no effect of culture media and plate-count techniques in the estimation of microbial count while the highly significant effect of other factors (type of microorganism, pharmaceutical product and individual reading and interpreting errors) was established. The most appropriate method of statistical analysis of such data was ANOVA which enabled not only the effect of individual factors to be estimated but also their interactions. Considering all the elements of uncertainty and combining them mathematically the combined relative uncertainty of the test results was estimated both for method of quantitative examination of non-sterile pharmaceuticals and microbial count technique without any product. These data did not exceed 35%, appropriated for a traditional plate count methods. Copyright © 2015 Elsevier B.V. All rights reserved.

Researchers have previously developed a multitude of methods designed to identify biological pathways associated with specific clinical or experimental conditions of interest, with the aim of facilitating biological interpretation of high-throughput data. Before practically applying such pathway analysis (PA) methods, we must first evaluate their performance and reliability, using datasets where the pathways perturbed by the conditions of interest have been well characterized in advance. However, such 'ground truths' (or gold standards) are often unavailable. Furthermore, previous evaluation strategies that have focused on defining 'true answers' are unable to systematically and objectively assess PA methods under a wide range of conditions. In this work, we propose a novel strategy for evaluating PA methods independently of any gold standard, either established or assumed. The strategy involves the use of two mutually complementary metrics, recall and discrimination. Recall measures the consistency of the perturbed pathways identified by applying a particular analysis method to an original large dataset and those identified by the same method to a sub-dataset of the original dataset. In contrast, discrimination measures specificity-the degree to which the perturbed pathways identified by a particular method to a dataset from one experiment differ from those identifying by the same method to a dataset from a different experiment. We used these metrics and 24 datasets to evaluate six widely used PA methods. The results highlighted the common challenge in reliably identifying significant pathways from small datasets. Importantly, we confirmed the effectiveness of our proposed dual-metric strategy by showing that previous comparative studies corroborate the performance evaluations of the six methods obtained by our strategy. Unlike any previously proposed strategy for evaluating the performance of PA methods, our dual-metric strategy does not rely on any ground truth

2008-01-01

Investment in commercial sodium cooled fast reactor (SFR) power plants will become possible only if SFRs achieve economic competitiveness as compared to light water reactors and other Generation IV reactors. Toward that end, we have launched efforts to improve the economics and safety of SFRs from the thermal design and safety analyses perspectives at Idaho National Laboratory. From the thermal design perspective, an innovative hybrid loop-pool SFR design has been proposed. This design takes advantage of the inherent safety of a pool design and the compactness of a loop design to further improve economics and safety. From the safety analyses perspective, we have initiated an effort to develop a high fidelity reactor system safety code

Brezina, Tadej; Graser, Anita; Leth, Ulrich

2017-04-01

Space, and in particular public space for movement and leisure, is a valuable and scarce resource, especially in today's growing urban centres. The distribution and absolute amount of urban space—especially the provision of sufficient pedestrian areas, such as sidewalks—is considered crucial for shaping living and mobility options as well as transport choices. Ubiquitous urban data collection and today's IT capabilities offer new possibilities for providing a relation-preserving overview and for keeping track of infrastructure changes. This paper presents three novel methods for estimating representative sidewalk widths and applies them to the official Viennese streetscape surface database. The first two methods use individual pedestrian area polygons and their geometrical representations of minimum circumscribing and maximum inscribing circles to derive a representative width of these individual surfaces. The third method utilizes aggregated pedestrian areas within the buffered street axis and results in a representative width for the corresponding road axis segment. Results are displayed as city-wide means in a 500 by 500 m grid and spatial autocorrelation based on Moran's I is studied. We also compare the results between methods as well as to previous research, existing databases and guideline requirements on sidewalk widths. Finally, we discuss possible applications of these methods for monitoring and regression analysis and suggest future methodological improvements for increased accuracy.

2014-01-01

The prompt decay constant α has significant application on the physical design and safety analysis in nuclear facilities. To overcome the difficulty of a value calculation with Monte-Carlo method, and improve the precision, a new method based on the neutron noise analysis technology was presented. This method employs the stochastic simulation and the theory of neutron noise analysis technology. Firstly, the evolution of stochastic neutron was simulated by discrete-events Monte-Carlo method based on the theory of generalized Semi-Markov process, then the neutron noise in detectors was solved from neutron signal. Secondly, the neutron noise analysis methods such as Rossia method, Feynman-α method, zero-probability method, and cross-correlation method were used to calculate a value. All of the parameters used in neutron noise analysis method were calculated based on auto-adaptive arithmetic. The a value from these methods accords with each other, the largest relative deviation is 7.9%, which proves the feasibility of a calculation method based on neutron noise analysis stochastic simulation.

Gouvela, John

2004-01-01

Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes. Over the next six years, we expect these methodologies to merge with other improvements into a consolidated office culture with all processes being guided by

A biosegmentation benchmark for evaluation of bioimage analysis methods

Directory of Open Access Journals (Sweden)

Kvilekval Kristian

2009-11-01

Full Text Available Abstract Background We present a biosegmentation benchmark that includes infrastructure, datasets with associated ground truth, and validation methods for biological image analysis. The primary motivation for creating this resource comes from the fact that it is very difficult, if not impossible, for an end-user to choose from a wide range of segmentation methods available in the literature for a particular bioimaging problem. No single algorithm is likely to be equally effective on diverse set of images and each method has its own strengths and limitations. We hope that our benchmark resource would be of considerable help to both the bioimaging researchers looking for novel image processing methods and image processing researchers exploring application of their methods to biology. Results Our benchmark consists of different classes of images and ground truth data, ranging in scale from subcellular, cellular to tissue level, each of which pose their own set of challenges to image analysis. The associated ground truth data can be used to evaluate the effectiveness of different methods, to improve methods and to compare results. Standard evaluation methods and some analysis tools are integrated into a database framework that is available online at http://bioimage.ucsb.edu/biosegmentation/. Conclusion This online benchmark will facilitate integration and comparison of image analysis methods for bioimages. While the primary focus is on biological images, we believe that the dataset and infrastructure will be of interest to researchers and developers working with biological image analysis, image segmentation and object tracking in general.

Academic dishonesty today, unethical practices tomorrow?

Science.gov (United States)

LaDuke, Rebekah D

2013-01-01

The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

The analytical study of the logic circuits described in this report clearly shows the fruitful efficiency of the methods proposed by Binary Analysis. This study is a very new approach in logic and these mathematical methods are systematically precise in their applications. The detailed operations of an automatic system are to be studied in a way which cannot be reached by other methods. The definition and utilization of transition equations allow the determination of the different commutations in the auxiliary switch functions of a sequential system. This new way of analysis digital circuits will certainly develop in a very near future [fr

Neutron activation analysis: principle and methods

Reddy, A.V.R.; Acharya, R.

2006-01-01

Neutron activation analysis (NAA) is a powerful isotope specific nuclear analytical technique for simultaneous determination of elemental composition of major, minor and trace elements in diverse matrices. The technique is capable of yielding high analytical sensitivity and low detection limits (ppm to ppb). Due to high penetration power of neutrons and gamma rays, NAA experiences negligible matrix effects in the samples of different origins. Depending on the sample matrix and element of interest NAA technique is used non-destructively, known as instrumental neutron activation analysis (INAA), or through chemical NAA methods. The present article describes principle of NAA, different methods and gives a overview some applications in the fields like environment, biology, geology, material sciences, nuclear technology and forensic sciences.

Analysis of concrete beams using applied element method

Science.gov (United States)

Lincy Christy, D.; Madhavan Pillai, T. M.; Nagarajan, Praveen

2018-03-01

The Applied Element Method (AEM) is a displacement based method of structural analysis. Some of its features are similar to that of Finite Element Method (FEM). In AEM, the structure is analysed by dividing it into several elements similar to FEM. But, in AEM, elements are connected by springs instead of nodes as in the case of FEM. In this paper, background to AEM is discussed and necessary equations are derived. For illustrating the application of AEM, it has been used to analyse plain concrete beam of fixed support condition. The analysis is limited to the analysis of 2-dimensional structures. It was found that the number of springs has no much influence on the results. AEM could predict deflection and reactions with reasonable degree of accuracy.

Fujikawa, Takeshi; Kurohashi, Michiya; Inoue, Yoshio

1975-01-01

Modal analysis method was developed for the vibration analysis of piping system in nuclear or chemical plants, with finite element theory, and verified by sinusoidal vibration method. The natural vibration equation for pipings was derived with stiffness, attenuation and mass matrices, and eigenvalues are obtained with usual method, then the forced vibration equation for pipings was derived with the same manner, and the special solutions are given by modal method from the eigenvalues of the natural vibration equation. Three simple piping models (one, two and three dimensional) were made, and the natural vibration frequency was measured with forced input from an electrical dynamic shaker and a sound speaker. The experimental values of natural vibration frequency showed good agreement with the results by the analytical method. Therefore the theoretical approach for piping system vibration was proved to be valid. (Iwase, T.)

Methods for Recovering Microorganisms from Solid Surfaces Used in the Food Industry: A Review of the Literature

Directory of Open Access Journals (Sweden)

Perrine Gay-Perret

2013-11-01

Full Text Available Various types of surfaces are used today in the food industry, such as plastic, stainless steel, glass, and wood. These surfaces are subject to contamination by microorganisms responsible for the cross-contamination of food by contact with working surfaces. The HACCP-based processes are now widely used for the control of microbial hazards to prevent food safety issues. This preventive approach has resulted in the use of microbiological analyses of surfaces as one of the tools to control the hygiene of products. A method of recovering microorganisms from different solid surfaces is necessary as a means of health prevention. No regulation exists for surface microbial contamination, but food companies tend to establish technical specifications to add value to their products and limit contamination risks. The aim of this review is to present the most frequently used methods: swabbing, friction or scrubbing, printing, rinsing or immersion, sonication and scraping or grinding and describe their advantages and drawbacks. The choice of the recovery method has to be suitable for the type and size of the surface tested for microbiological analysis. Today, quick and cheap methods have to be standardized and especially easy to perform in the field.

Substructure method has been preferably adopted for soil-structure interaction analysis because of its simplicity and economy in practical application. However, substructure method has some limitation in application and does not always give reliable results especially for embedded structures or layered soil conditions. The objective of this study to validate the reliability of the soil-structure interaction analysis results by the proposed substructure method using lumped-parameter model and suggest a method of seismic design of nuclear power plant structures with specific design conditions. In this study, theoretic background and modeling technique of soil-structure interaction phenomenon have been reviewed and an analysis technique based on substructure method using lumped-parameter model has been suggested. The practicality and reliability of the proposed method have been validated through the application of the method to the seismic analysis of the large-scale seismic test models. A technical guide for practical application and evaluation of the proposed method have been also provided through the various type parametric.

Phase Plane Analysis Method of Nonlinear Traffic Phenomena

Directory of Open Access Journals (Sweden)

Wenhuan Ai

2015-01-01

Full Text Available A new phase plane analysis method for analyzing the complex nonlinear traffic phenomena is presented in this paper. This method makes use of variable substitution to transform a traditional traffic flow model into a new model which is suitable for the analysis in phase plane. According to the new model, various traffic phenomena, such as the well-known shock waves, rarefaction waves, and stop-and-go waves, are analyzed in the phase plane. From the phase plane diagrams, we can see the relationship between traffic jams and system instability. So the problem of traffic flow could be converted into that of system stability. The results show that the traffic phenomena described by the new method is consistent with that described by traditional methods. Moreover, the phase plane analysis highlights the unstable traffic phenomena we are chiefly concerned about and describes the variation of density or velocity with time or sections more clearly.

Stochastic seismic floor response analysis method for various damping systems

International Nuclear Information System (INIS)

Kitada, Y.; Hattori, K.; Ogata, M.; Kanda, J.

1991-01-01

A study using the stochastic seismic response analysis method which is applicable for the estimation of floor response spectra is carried out. It is pointed out as a shortcoming in this stochastic seismic response analysis method, that the method tends to overestimate floor response spectra for low damping systems, e.g. 1% of the critical damping ratio. An investigation on the cause of the shortcoming is carried out and a number of improvements in this method were also made to the original method by taking correlation of successive peaks in a response time history into account. The application of the improved method to a typical BWR reactor building is carried out. The resultant floor response spectra are compared with those obtained by deterministic time history analysis. Floor response spectra estimated by the improved method consistently cover the response spectra obtained by the time history analysis for various damping ratios. (orig.)

The concept of the hierarchical fuzzy rule based method aims to evaluate the data from virtual team interaction instances related to implementation of project tasks. The suggested method is designed for project managers or virtual team leaders to help in virtual teamwork evaluation that is based on captured data analysis. The main point of the method is the ability to repeat human thinking and expert valuation process for data analysis by applying fuzzy logic: fuzzy sets, fuzzy signatures and fuzzy rules. The fuzzy set principle used in the method allows evaluation criteria numerical values to transform into linguistic terms and use it in constructing fuzzy rules. Using a fuzzy signature is possible in constructing a hierarchical criteria structure. This structure helps to solve the problem of exponential increase of fuzzy rules including more input variables. The suggested method is aimed to be applied in the virtual collaboration software as a real time teamwork evaluation tool. The research shows that by applying fuzzy logic for team collaboration data analysis it is possible to get evaluations equal to expert insights. The method includes virtual team, project task and team collaboration data analysis. The advantage of the suggested method is the possibility to use variables gained from virtual collaboration systems as fuzzy rules inputs. Information on fuzzy logic based virtual teamwork collaboration evaluation has evidence that can be investigated in the future. Also the method can be seen as the next virtual collaboration software development step.

An advanced probabilistic structural analysis method for implicit performance functions

1989-01-01

In probabilistic structural analysis, the performance or response functions usually are implicitly defined and must be solved by numerical analysis methods such as finite element methods. In such cases, the most commonly used probabilistic analysis tool is the mean-based, second-moment method which provides only the first two statistical moments. This paper presents a generalized advanced mean value (AMV) method which is capable of establishing the distributions to provide additional information for reliability design. The method requires slightly more computations than the second-moment method but is highly efficient relative to the other alternative methods. In particular, the examples show that the AMV method can be used to solve problems involving non-monotonic functions that result in truncated distributions.

Overview of methods for uncertainty analysis and sensitivity analysis in probabilistic risk assessment

International Nuclear Information System (INIS)

Iman, R.L.; Helton, J.C.

1985-01-01

Probabilistic Risk Assessment (PRA) is playing an increasingly important role in the nuclear reactor regulatory process. The assessment of uncertainties associated with PRA results is widely recognized as an important part of the analysis process. One of the major criticisms of the Reactor Safety Study was that its representation of uncertainty was inadequate. The desire for the capability to treat uncertainties with the MELCOR risk code being developed at Sandia National Laboratories is indicative of the current interest in this topic. However, as yet, uncertainty analysis and sensitivity analysis in the context of PRA is a relatively immature field. In this paper, available methods for uncertainty analysis and sensitivity analysis in a PRA are reviewed. This review first treats methods for use with individual components of a PRA and then considers how these methods could be combined in the performance of a complete PRA. In the context of this paper, the goal of uncertainty analysis is to measure the imprecision in PRA outcomes of interest, and the goal of sensitivity analysis is to identify the major contributors to this imprecision. There are a number of areas that must be considered in uncertainty analysis and sensitivity analysis for a PRA: (1) information, (2) systems analysis, (3) thermal-hydraulic phenomena/fission product behavior, (4) health and economic consequences, and (5) display of results. Each of these areas and the synthesis of them into a complete PRA are discussed

Probabilistic methods in fire-risk analysis

International Nuclear Information System (INIS)

Brandyberry, M.D.

1989-01-01

The first part of this work outlines a method for assessing the frequency of ignition of a consumer product in a building and shows how the method would be used in an example scenario utilizing upholstered furniture as the product and radiant auxiliary heating devices (electric heaters, wood stoves) as the ignition source. Deterministic thermal models of the heat-transport processes are coupled with parameter uncertainty analysis of the models and with a probabilistic analysis of the events involved in a typical scenario. This leads to a distribution for the frequency of ignition for the product. In second part, fire-risk analysis as currently used in nuclear plants is outlines along with a discussion of the relevant uncertainties. The use of the computer code COMPBRN is discussed for use in the fire-growth analysis along with the use of response-surface methodology to quantify uncertainties in the code's use. Generalized response surfaces are developed for temperature versus time for a cable tray, as well as a surface for the hot gas layer temperature and depth for a room of arbitrary geometry within a typical nuclear power plant compartment. These surfaces are then used to simulate the cable tray damage time in a compartment fire experiment

Methods of charged-particle activation analysis

Chaudhri, M. Anwar; Chaudhri, M. Nasir; Jabbar, Q.; Nadeem, Q.

2006-01-01

The accuracy of Chaudhri's method for charged-particle activation analysis published in J. Radioanal. Chem. (1977) v. 37 p. 243 has been further demonstrated by extensive calculations. The nuclear reactions 12 C(d,n) 13 N, 63 Cu( 3 He,p) 65 Zn, 107 Ag(α,n) 110 In and 208 Pb(d,p) 209 Pb, the cross sections of which were easily available, have been examined for the detection of 12 C, 63 Cu, 107 Ag and 208 Pb, respectively, in matrices of Cu, Zr and Pb, at the bombarding energies of 4 - 22 MeV. The 'standard' is assumed to be in a carbon matrix. It has been clearly demonstrated that Chaudhri's method, which makes the charged particle activation analysis as simple as neutron activation analysis, provides results which are almost identical to, or only about 1-2 % different, from the results obtained using the full 'Activity Equation' involving solving complex integrals. It is valid even when the difference in the average atomic weights of matrices of the standard and the sample is large. (author)

The same analysis approach: Practical protection against the pitfalls of novel neuroimaging analysis methods.

Science.gov (United States)

Görgen, Kai; Hebart, Martin N; Allefeld, Carsten; Haynes, John-Dylan

2017-12-27

Standard neuroimaging data analysis based on traditional principles of experimental design, modelling, and statistical inference is increasingly complemented by novel analysis methods, driven e.g. by machine learning methods. While these novel approaches provide new insights into neuroimaging data, they often have unexpected properties, generating a growing literature on possible pitfalls. We propose to meet this challenge by adopting a habit of systematic testing of experimental design, analysis procedures, and statistical inference. Specifically, we suggest to apply the analysis method used for experimental data also to aspects of the experimental design, simulated confounds, simulated null data, and control data. We stress the importance of keeping the analysis method the same in main and test analyses, because only this way possible confounds and unexpected properties can be reliably detected and avoided. We describe and discuss this Same Analysis Approach in detail, and demonstrate it in two worked examples using multivariate decoding. With these examples, we reveal two sources of error: A mismatch between counterbalancing (crossover designs) and cross-validation which leads to systematic below-chance accuracies, and linear decoding of a nonlinear effect, a difference in variance.

Dual ant colony operational modal analysis parameter estimation method

Science.gov (United States)

Sitarz, Piotr; Powałka, Bartosz

2018-01-01

Operational Modal Analysis (OMA) is a common technique used to examine the dynamic properties of a system. Contrary to experimental modal analysis, the input signal is generated in object ambient environment. Operational modal analysis mainly aims at determining the number of pole pairs and at estimating modal parameters. Many methods are used for parameter identification. Some methods operate in time while others in frequency domain. The former use correlation functions, the latter - spectral density functions. However, while some methods require the user to select poles from a stabilisation diagram, others try to automate the selection process. Dual ant colony operational modal analysis parameter estimation method (DAC-OMA) presents a new approach to the problem, avoiding issues involved in the stabilisation diagram. The presented algorithm is fully automated. It uses deterministic methods to define the interval of estimated parameters, thus reducing the problem to optimisation task which is conducted with dedicated software based on ant colony optimisation algorithm. The combination of deterministic methods restricting parameter intervals and artificial intelligence yields very good results, also for closely spaced modes and significantly varied mode shapes within one measurement point.

Computational methods for nuclear criticality safety analysis

International Nuclear Information System (INIS)

Maragni, M.G.

1992-01-01

Nuclear criticality safety analyses require the utilization of methods which have been tested and verified against benchmarks results. In this work, criticality calculations based on the KENO-IV and MCNP codes are studied aiming the qualification of these methods at the IPEN-CNEN/SP and COPESP. The utilization of variance reduction techniques is important to reduce the computer execution time, and several of them are analysed. As practical example of the above methods, a criticality safety analysis for the storage tubes for irradiated fuel elements from the IEA-R1 research has been carried out. This analysis showed that the MCNP code is more adequate for problems with complex geometries, and the KENO-IV code shows conservative results when it is not used the generalized geometry option.

Present status of reactor physics in the United States and Japan-II. 1. Deterministic Transport Methods for Reactor Analysis

International Nuclear Information System (INIS)

Adams, Marvin L.

2001-01-01

We discuss deterministic transport methods used today in neutronic analysis of nuclear reactors. This discussion is not exhaustive; our goal is to provide an overview of the methods that are most widely used for analyzing light water reactors (LWRs) and that (in our opinion) hold the most promise for the future. The current practice of LWR analysis involves the following steps: 1. Evaluate cross sections from measurements and models. 2. Obtain weighted-average cross sections over dozens to hundreds of energy intervals; the result is a 'fine-group' cross-section set. 3. [Optional] Modify the fine-group set: Further collapse it using information specific to your class of reactors and/or alter parameters so that computations better agree with experiments. The result is a 'many-group library'. 4. Perform pin cell transport calculations (usually one-dimensional cylindrical); use the results to collapse the many-group library to a medium-group set, and/or spatially average the cross sections over the pin cells. 5. Perform assembly-level transport calculations with the medium-group set. It is becoming common practice to use essentially exact geometry (no pin cell homogenization). It may soon become common to skip step 4 and use the many-group library. The output is a library of few-group cross sections, spatially averaged over the assembly, parameterized to cover the full range of operating conditions. 6. Perform full-core calculations with few-group diffusion theory that contains significant homogenizations and limited transport corrections. We discuss steps 4, 5, and 6 and focus mainly on step 5. One cannot review a large topic in a short summary without simplifying reality, omitting important details, and neglecting some methods that deserve attention; for this we apologize in advance.

[Health care in today's Western Belarus in the inter-war period (1921-1939)].

Science.gov (United States)

Tiszczenko, E M

2001-01-01

During the inter-war period, today's Western Belarus, which under the Treaty of Riga constituted part of the Second Polish Republic, stood out for its higher morbidity in various disease categories than other regions of the country. Heightened threats of epidemics prevailed in that area, and typhoid fever, trachoma, tuberculois and venereal disease were serious health problems. Specific features of the health care of today's Western Belarus could be observed that set it apart from both that of Eastern Belarus forming a part of the Soviet Union as well as from the central and western provinces of Poland. Compared with Eastern Belarus, there was a lack of health services, including anti-tuberculosis, anti-venereal and paediatric dispensaries, or they were in the process of being created. But physicians' self-government bodies functioned, as did out-patient care with dispensary-like elements and health care provided by local health centres. There also existed the institution of full-time family doctors within the insured health-care system - something lacking in Eastern Belarus. As in other voivodships (provinces) of the Second Republic, there existed multi-sector health care: state, local, insurance-based and private. The Western Belarus had Poland's smallest number of physicians, new hospital beds and pharmacies. On the other hand, today's Western Belarus stands out by virtue of maintaining field-medicine traditions. To this day, assistant medical officers provide health care to the rural population - an arrangement not typical of the central and western provinces fo pre-war Poland.

Bayesian data analysis in population ecology: motivations, methods, and benefits

Science.gov (United States)

Dorazio, Robert

2016-01-01

During the 20th century ecologists largely relied on the frequentist system of inference for the analysis of their data. However, in the past few decades ecologists have become increasingly interested in the use of Bayesian methods of data analysis. In this article I provide guidance to ecologists who would like to decide whether Bayesian methods can be used to improve their conclusions and predictions. I begin by providing a concise summary of Bayesian methods of analysis, including a comparison of differences between Bayesian and frequentist approaches to inference when using hierarchical models. Next I provide a list of problems where Bayesian methods of analysis may arguably be preferred over frequentist methods. These problems are usually encountered in analyses based on hierarchical models of data. I describe the essentials required for applying modern methods of Bayesian computation, and I use real-world examples to illustrate these methods. I conclude by summarizing what I perceive to be the main strengths and weaknesses of using Bayesian methods to solve ecological inference problems.

Two-level method with coarse space size independent convergence

Energy Technology Data Exchange (ETDEWEB)

Vanek, P.; Brezina, M. [Univ. of Colorado, Denver, CO (United States); Tezaur, R.; Krizkova, J. [UWB, Plzen (Czech Republic)

1996-12-31

The basic disadvantage of the standard two-level method is the strong dependence of its convergence rate on the size of the coarse-level problem. In order to obtain the optimal convergence result, one is limited to using a coarse space which is only a few times smaller than the size of the fine-level one. Consequently, the asymptotic cost of the resulting method is the same as in the case of using a coarse-level solver for the original problem. Today`s two-level domain decomposition methods typically offer an improvement by yielding a rate of convergence which depends on the ratio of fine and coarse level only polylogarithmically. However, these methods require the use of local subdomain solvers for which straightforward application of iterative methods is problematic, while the usual application of direct solvers is expensive. We suggest a method diminishing significantly these difficulties.

Novel variational approach for analysis of photonic crystal slabs

International Nuclear Information System (INIS)

Aram, Mohammad Hasan; Khorasani, Sina

2015-01-01

We propose a new method, based on variational principle, for the analysis of photonic crystal (PC) slabs. Most of the methods used today treat PC slabs as three-dimensional (3D) crystal, and this makes these methods very time and/or memory consuming. In our proposed method, we use the Bloch theorem to expand the field on infinite plane waves, whose amplitudes depend on the component perpendicular to the slab surface. By approximating these amplitudes with appropriate functions, we can find modes of PC slabs almost as fast as we can find modes of two-dimensional crystals. In addition to this advantage, we can also calculate radiation modes with this method, which is not feasible with the 3D plane wave expansion method. (paper)

Sustainable power and scenic beauty: The Niagara River Water Diversion Treaty and its relevance today

International Nuclear Information System (INIS)

Sedoff, Andrei; Schott, Stephan; Karney, Bryan

2014-01-01

Niagara Falls and the Niagara River have always attracted great public interest due to their natural beauty, their enormous potential for electricity generation, their recreational value and as an important ecosystem. There have been simultaneous efforts to preserve this unique natural wonder and harness its power through hydroelectric development projects by both the United States and Canada. This paper explores the evolution of these efforts that culminated with the signing of the 1950 Niagara River Water Diversion Treaty that established minimum water flow rates to protect the “scenic beauty” of the falls, allowing the remaining water to be diverted for power production. We examine the rationale that led to specific water flow restrictions and question to what extent they are relevant today, as water intake capacity on the Canadian side has just been extended by around 25%. We find that current restrictions under the Niagara River Water Treaty (that expired in 2000) are not based on sound scientific evidence and estimate the upper limit of potential foregone benefits from clean electricity generation and greenhouse gas reductions. We identify a number of important issues that emerged in the last decades and that would justify an exploration of new treaty rules. - Highlights: • We examine the history of water diversion at Niagara Falls. • We examine the rationale that led to water flow restrictions over Niagara Falls and its relevance today. • We estimate the opportunity cost of foregone energy generation with the new Canadian intake capacity. • Water flow stipulations were not based on the sound scientific or ecosystem analysis. • A renegotiation of the 1950 Niagara River Water Diversion Treaty is overdue

Method of signal analysis

International Nuclear Information System (INIS)

Berthomier, Charles

1975-01-01

A method capable of handling the amplitude and the frequency time laws of a certain kind of geophysical signals is described here. This method is based upon the analytical signal idea of Gabor and Ville, which is constructed either in the time domain by adding an imaginary part to the real signal (in-quadrature signal), or in the frequency domain by suppressing negative frequency components. The instantaneous frequency of the initial signal is then defined as the time derivative of the phase of the analytical signal, and his amplitude, or envelope, as the modulus of this complex signal. The method is applied to three types of magnetospheric signals: chorus, whistlers and pearls. The results obtained by analog and numerical calculations are compared to results obtained by classical systems using filters, i.e. based upon a different definition of the concept of frequency. The precision with which the frequency-time laws are determined leads then to the examination of the principle of the method and to a definition of instantaneous power density spectrum attached to the signal, and to the first consequences of this definition. In this way, a two-dimensional representation of the signal is introduced which is less deformed by the analysis system properties than the usual representation, and which moreover has the advantage of being obtainable practically in real time [fr

The application of instrumental neutron activation analysis for the determination of long-lived rare earth elements (REE) in rock samples is considered in this work. Two different methods are statistically compared: the well established external standard method carried out using standard reference materials, and the internal standard method (ISM), using Fe, determined through X-ray fluorescence analysis, as an element-comparator. The ISM proved to be the more precise method for a wide range of REE contents and can be recommended for routine practice. (author)

An electromagnetic modeling method for eddy current signal analysis is necessary before an experiment is performed. Electromagnetic modeling methods consists of the analytical method and the numerical method. Also, the numerical methods can be divided by Finite Element Method(FEM), Boundary Element Method(BEM) and Volume Integral Method(VIM). Each modeling method has some merits and demerits. Therefore, the suitable modeling method can be chosen by considering the characteristics of each modeling. This report explains the principle and application of each modeling method and shows the comparison modeling programs

Multiple predictor smoothing methods for sensitivity analysis.

Energy Technology Data Exchange (ETDEWEB)

Helton, Jon Craig; Storlie, Curtis B.

2006-08-01

The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Specifically, sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (1) locally weighted regression (LOESS), (2) additive models, (3) projection pursuit regression, and (4) recursive partitioning regression. The indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility (i.e., the Waste Isolation Pilot Plant). As shown by the example illustrations, the use of smoothing procedures based on nonparametric regression techniques can yield more informative sensitivity analysis results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and model predictions are present.

2002-01-01

The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of th...

Ignatius of Loyola on medical education. Or: Should today's Jesuits continue to run health sciences schools?

Science.gov (United States)

Welie, Jos V M

2003-01-01

There are present 28 Jesuit colleges and universities in the United States, which together offer more than 50 health sciences degree programs. But as the Society's membership is shrinking and the financial risks involved in sponsoring health sciences education are rising, the question arises whether the Society should continue to sponsor health sciences degree programs. In fact, at least eight Jesuit health sciences schools have already closed their doors. This paper attempts to contribute to the resolution of this urgent question by reexamining Ignatius own views on health sciences education and, more specifically, his prohibition of the Society's sponsoring medical education. It concludes on the basis of an historical analysis of Ignatius' views that there is insufficient support for today's Jesuits to maintain their engagement in medical and health care education.

Stress classification is not only one of key steps when pressure vessel component is designed by analysis, but also a difficulty which puzzles engineers and designers at all times. At present, for calculating and categorizing the stress field of pressure vessel components, there are several computation methods of design by analysis such as Stress Equivalent Linearization, Two-Step Approach, Primary Structure method, Elastic Compensation method, GLOSS R-Node method and so on, that are developed and applied. Moreover, ASME code also gives an inelastic method of design by analysis for limiting gross plastic deformation only. When pressure vessel components design by analysis, sometimes there are huge differences between the calculating results for using different calculating and analysis methods mentioned above. As consequence, this is the main reason that affects wide application of design by analysis approach. Recently, a new approach, presented in the new proposal of a European Standard, CEN's unfired pressure vessel standard EN 13445-3, tries to avoid problems of stress classification by analyzing pressure vessel structure's various failure mechanisms directly based on elastic-plastic theory. In this paper, some stress classification methods mentioned above, are described briefly. And the computational methods cited in the European pressure vessel standard, such as Deviatoric Map, and nonlinear analysis methods (plastic analysis and limit analysis), are depicted compendiously. Furthermore, the characteristics of computational methods of design by analysis are summarized for selecting the proper computational method when design pressure vessel component by analysis.

Three-Phase Harmonic Analysis Method for Unbalanced Distribution Systems

Directory of Open Access Journals (Sweden)

Jen-Hao Teng

2014-01-01

Full Text Available Due to the unbalanced features of distribution systems, a three-phase harmonic analysis method is essential to accurately analyze the harmonic impact on distribution systems. Moreover, harmonic analysis is the basic tool for harmonic filter design and harmonic resonance mitigation; therefore, the computational performance should also be efficient. An accurate and efficient three-phase harmonic analysis method for unbalanced distribution systems is proposed in this paper. The variations of bus voltages, bus current injections and branch currents affected by harmonic current injections can be analyzed by two relationship matrices developed from the topological characteristics of distribution systems. Some useful formulas are then derived to solve the three-phase harmonic propagation problem. After the harmonic propagation for each harmonic order is calculated, the total harmonic distortion (THD for bus voltages can be calculated accordingly. The proposed method has better computational performance, since the time-consuming full admittance matrix inverse employed by the commonly-used harmonic analysis methods is not necessary in the solution procedure. In addition, the proposed method can provide novel viewpoints in calculating the branch currents and bus voltages under harmonic pollution which are vital for harmonic filter design. Test results demonstrate the effectiveness and efficiency of the proposed method.

Ransom, Jonathan B.; Broduer, Steve (Technical Monitor)

2001-01-01

Engineers are challenged to produce better designs in less time and for less cost. Hence, to investigate novel and revolutionary design concepts, accurate, high-fidelity results must be assimilated rapidly into the design, analysis, and simulation process. This assimilation should consider diverse mathematical modeling and multi-discipline interactions necessitated by concepts exploiting advanced materials and structures. Integrated high-fidelity methods with diverse engineering applications provide the enabling technologies to assimilate these high-fidelity, multi-disciplinary results rapidly at an early stage in the design. These integrated methods must be multifunctional, collaborative, and applicable to the general field of engineering science and mechanics. Multifunctional methodologies and analysis procedures are formulated for interfacing diverse subdomain idealizations including multi-fidelity modeling methods and multi-discipline analysis methods. These methods, based on the method of weighted residuals, ensure accurate compatibility of primary and secondary variables across the subdomain interfaces. Methods are developed using diverse mathematical modeling (i.e., finite difference and finite element methods) and multi-fidelity modeling among the subdomains. Several benchmark scalar-field and vector-field problems in engineering science are presented with extensions to multidisciplinary problems. Results for all problems presented are in overall good agreement with the exact analytical solution or the reference numerical solution. Based on the results, the integrated modeling approach using the finite element method for multi-fidelity discretization among the subdomains is identified as most robust. The multiple-method approach is advantageous when interfacing diverse disciplines in which each of the method's strengths are utilized. The multifunctional methodology presented provides an effective mechanism by which domains with diverse idealizations are

Full Text Available The paper presents a method for the analysis of nonlinear behaviour of reinforced concrete bent elements subjected to short-term static load. The considerations in the range of modelling of deformation processes of reinforced concrete element were carried out. The method of structure effort analysis was developed using the finite difference method. The Dynamic Relaxation Method, which — after introduction of critical damping — allows for description of the static behaviour of a structural element, was used to solve the system of nonlinear equilibrium equations. In order to increase the method effectiveness in the range of the post-critical analysis, the Arc Length Parameter on the equilibrium path was introduced into the computational procedure.[b]Keywords[/b]: reinforced concrete elements, physical nonlinearity, geometrical nonlinearity, dynamic relaxation method, arc-length method

Skateboarding injuries of today

Forsman, L; Eriksson, A

2001-01-01

Background—Skateboarding injuries have increased with the rise in popularity of the sport, and the injury pattern can be expected to have changed with the development of both skateboard tricks and the materials used for skateboard construction. Objective—To describe the injury pattern of today. Methods—The pattern of injuries, circumstances, and severity were investigated in a study of all 139 people injured in skateboarding accidents during the period 1995–1998 inclusive and admitted to the University Hospital of Umeå. This is the only hospital in the area, serving a population of 135 000. Results—Three of the 139 injured were pedestrians hit by a skateboard rider; the rest were riders. The age range was 7–47 years (mean 16). The severity of the injuries was minor (AIS 1) to moderate (AIS 2); fractures were classified as moderate. The annual number of injuries increased during the study period. Fractures were found in 29% of the casualties, and four children had concussion. The most common fractures were of the ankle and wrist. Older patients had less severe injuries, mainly sprains and soft tissue injuries. Most children were injured while skateboarding on ramps and at arenas; only 12 (9%) were injured while skateboarding on roads. Some 37% of the injuries occurred because of a loss of balance, and 26% because of a failed trick attempt. Falls caused by surface irregularities resulted in the highest proportion of the moderate injuries. Conclusions—Skateboarding should be restricted to supervised skateboard parks, and skateboarders should be required to wear protective gear. These measures would reduce the number of skateboarders injured in motor vehicle collisions, reduce the personal injuries among skateboarders, and reduce the number of pedestrians injured in collisions with skateboarders.

Mitchell, Cassie S; Cates, Ashlyn; Kim, Renaid B; Hollinger, Sabrina K

2015-01-01

Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

2009-12-01

Among the towns constellating the Dalmatian coast, Ragusa (today Dubrovnik, Croatia), stands out, both because of its location in the middle of the Eastern Adriatic coast and its long-lasting, independent history of a Modern Age town and its small coastal territory. An important intelligence crossroads, squeezed as it was in between powerful and influential neighbours, such as the Ottoman Empire and the Republic of Venice, in its history (1358-1808) the Republic of Ragusa did experience heavily damaging earthquakes. We narrate the story of these earthquakes, which were recorded in the historical documentation of the Republic (today stored at the State Archives of Dubrovnik - Drzavni arhiv u Dubrovniku) as well as in documents from officers of other Mediterranean countries and letters of individuals. Of special note is the 6 April 1667 earthquake, which inflicted a permanent scar on the Republic. The earthquake's direct effects and their consequences caused a serious financial crisis, so critical that it took over 50 years for Ragusa to recover. This large earthquake is reappraised on the basis of newly investigated sources, and effects of the damage within the city walls are detailed. A seismic history of Ragusa is finally proposed, supported by full-text coeval records.

Methods for Force Analysis of Overconstrained Parallel Mechanisms: A Review

Liu, Wen-Lan; Xu, Yun-Dou; Yao, Jian-Tao; Zhao, Yong-Sheng

2017-11-01

The force analysis of overconstrained PMs is relatively complex and difficult, for which the methods have always been a research hotspot. However, few literatures analyze the characteristics and application scopes of the various methods, which is not convenient for researchers and engineers to master and adopt them properly. A review of the methods for force analysis of both passive and active overconstrained PMs is presented. The existing force analysis methods for these two kinds of overconstrained PMs are classified according to their main ideas. Each category is briefly demonstrated and evaluated from such aspects as the calculation amount, the comprehensiveness of considering limbs' deformation, and the existence of explicit expressions of the solutions, which provides an important reference for researchers and engineers to quickly find a suitable method. The similarities and differences between the statically indeterminate problem of passive overconstrained PMs and that of active overconstrained PMs are discussed, and a universal method for these two kinds of overconstrained PMs is pointed out. The existing deficiencies and development directions of the force analysis methods for overconstrained systems are indicated based on the overview.

In a recent paper, Pietro Cipresso et al proposed the PsychoPass method, a simple way to create strong passwords that are easy to remember. However, the method has some security issues that need to be addressed. To perform a security analysis on the PsychoPass method and outline the limitations of and possible improvements to the method. We used the brute force analysis and dictionary attack analysis of the PsychoPass method to outline its weaknesses. The first issue with the Psychopass method is that it requires the password reproduction on the same keyboard layout as was used to generate the password. The second issue is a security weakness: although the produced password is 24 characters long, the password is still weak. We elaborate on the weakness and propose a solution that produces strong passwords. The proposed version first requires the use of the SHIFT and ALT-GR keys in combination with other keys, and second, the keys need to be 1-2 distances apart. The proposed improved PsychoPass method yields passwords that can be broken only in hundreds of years based on current computing powers. The proposed PsychoPass method requires 10 keys, as opposed to 20 keys in the original method, for comparable password strength.

Lempen, Olivia; Midgley, Nick

2006-01-01

The aim of this research study was to investigate the role of children's dreams in the practice of child psychoanalysis today, and to explore contemporary psychoanalytic understanding of children's dreams. This pilot study consisted of two stages. The first involved a document analysis of published articles in The Psychoanalytic Study of the Child, making a comparison between those of the early 1950s and the 1990s, in order to see in what way the discourse around children's dreams within the psychoanalytic literature has changed over time. The second stage, based on questionnaires and in-depth interviews, attempted to understand in more detail the way contemporary child analysts, working in the Anna Freudian tradition, think about dreams and use them in their clinical practice. Results suggest that there has been a decreased focus on dreams in a clinical context over time, and that this may partly be a consequence of changing theoretical models and changes in training. When work with dreams does take place, it appears that child analysts have

Nurse leaders' perceptions of what compromises successful leadership in today's acute inpatient environment.

The purpose of this study was to gain an understanding of nurse leaders' perceptions of both the value of their roles in today's health care setting and their beliefs about how power and gender interface with role worth. Support for the theoretical significance of this research stemmed from Kanter's Structural Theory of Organizational Behavior. Four leaders were recruited at the executive level and 12 at the director/managerial level. The results of the deductive analysis supported Kanter's theory. Eighty-three percent of the nurse leaders validated that access to power, opportunity, information, and resources created an empowered environment, producing a climate that fostered leadership success and enhanced levels of job satisfaction among nurses. This study provided groundwork on the kinds of leadership traits that foster nursing satisfaction and on whether or not gender influences leadership effectiveness. The findings of this study are both timely and relevant for nurse leaders faced with the effects of the current supply-and-demand nursing shortage and with fiscal restraints mandated by managed care and regulatory agencies.

The development and negotiation of an Engineering, Procurement and Construction (EPC) contract is a multi-disciplined and time consuming process. Relative to the first wave on new nuclear build projects of the 1950's - 1970's, today's EPC contracts are more complex for a variety of reasons including more demanding regulatory and environmental requirements, global supply chain versus localization issues and different world wide economic considerations. This paper discusses the impacts of some of these challenges on developing an EPC contract in today's Nuclear Renaissance. (authors)

The magnetic-relaxation method is considered of the quantitative analysis of inorganic substances based on time dependence of magnetic nuclei relaxation on the quantity of paramagnetic centres in a solution. The characteristic is given of some methods of measuring nuclear magnetic relaxation times: method of weak oscillation generator and pulse methods. The effect of temperature, general solution viscosity, diamagnetic salt concentration, medium acidity on nuclear relaxation velocity is described. The determination sensitivity is estimated and the means of its increase definable concentration intervals and method selectivity are considered. The method application when studying complexing in the solution is described. A particular attention is given to the investigation of heteroligand homocentre, heterocentre and protonated complexes as well as to the problems of particle exchange of the first coordination sphere with particles from the mass of solution. The equations for equilibrium constant calculation in different systems are given. Possibilities of determining diamagnetic ions by the magnetic-relaxation method using paramagnetic indicators are confirmed by the quantitative analysis of indium, gallium, thorium and scandium in their salt solutions

Dependability Analysis Methods For Configurable Software

Configurable software systems are systems which are built up by standard software components in the same way as a hardware system is built up by standard hardware components. Such systems are often used in the control of NPPs, also in safety related applications. A reliability analysis of such systems is therefore necessary. This report discusses what configurable software is, and what is particular with respect to reliability assessment of such software. Two very commonly used techniques in traditional reliability analysis, viz. failure mode, effect and criticality analysis (FMECA) and fault tree analysis are investigated. A real example is used to illustrate the discussed methods. Various aspects relevant to the assessment of the software reliability in such systems are discussed. Finally some models for quantitative software reliability assessment applicable on configurable software systems are described. (author)

Analysis of spectral methods for the homogeneous Boltzmann equation

KAUST Repository

Filbet, Francis; Mouhot, Clé ment

2011-01-01

The development of accurate and fast algorithms for the Boltzmann collision integral and their analysis represent a challenging problem in scientific computing and numerical analysis. Recently, several works were devoted to the derivation of spectrally accurate schemes for the Boltzmann equation, but very few of them were concerned with the stability analysis of the method. In particular there was no result of stability except when the method was modified in order to enforce the positivity preservation, which destroys the spectral accuracy. In this paper we propose a new method to study the stability of homogeneous Boltzmann equations perturbed by smoothed balanced operators which do not preserve positivity of the distribution. This method takes advantage of the "spreading" property of the collision, together with estimates on regularity and entropy production. As an application we prove stability and convergence of spectral methods for the Boltzmann equation, when the discretization parameter is large enough (with explicit bound). © 2010 American Mathematical Society.

Full Text Available the article considers models of risk assessment that can be applied to cargo transportation, for forecasting possible damage in the form of financial and material costs in order to reduce the percentage of probability of their occurrence. The analysis of risk by the method «Criterion. Event. Rule" is represented. This method is based on the collection of information by various methods, assigning an assessment to the identified risks, ranking and formulating a report on the analysis. It can be carried out as a fully manual mechanical method of information collecting and performing calculations or can be brought to an automated level from data collection to the delivery of finished results (but in this case some nuances that could significantly influence the outcome of the analysis can be ignored. The expert method is of particular importance, since it relies directly on human experience. In this case, a special role is played by the human factor. The collection of information and the assigned assessments to risk groups depend on the extent to which experts agree on this issue. The smaller the fluctuations in the values ​​of the estimates of the experts, the more accurate and optimal the results will be.

Metal speciation: survey of environmental methods of analysis

As part of a recent task under the EPRI Analytical Methods Qualification Program (RP 1851), TRW has surveyed the methods available for monitoring metal species in typical utility aqueous discharge streams. Methods for determining the individual species of these metals can become important in a regulatory sense as the EPA transitions to assessment of environmental risk based on bioavailability. For example, EPA considers methyl mercury and Cr(VI) much more toxic to the aquatic environment than inorganic mercury or Cr(III). The species of a given element can also differ in their transport and bioaccumulation. Methods for speciation generally include a selective separation step followed by standard metals analysis. Speciation, therefore, is mainly derived from the separation step and not from the method of final quantisation. Examples of separation/analysis include: selective extraction followed by graphite furnace atomic absorption or ICP-MS; separation by GC followed by metals detection; chelation and/or direct separation by LC followed by UV measurement or metals detection; and ion chromatography with conductivity, UV, or metals detection. There are a number of sampling issues associated with metal species such as stabilization (maintaining oxidation state), absorption, and filtration that need to be addressed in order to obtain and maintain a representative sample for analysis. 45 refs., 1 tab.

Economic analysis of alternative LLW disposal methods

Foutes, C.E.

1987-01-01

The Environmental Protection Agency (EPA) has evaluated the costs and benefits of alternative disposal technologies as part of its program to develop generally applicable environmental standards for the land disposal of low-level radioactive waste (LLW). Costs, population health effects and Critical Population Group (CPG) exposures resulting from alternative waste treatment and disposal methods were developed and input into the analysis. The cost-effectiveness analysis took into account a number of waste streams, hydrogeologic and climatic region settings, and waste treatment and disposal methods. Total costs of each level of a standard included costs for packaging, processing, transportation, and burial of waste. Benefits are defined in terms of reductions in the general population health risk (expected fatal cancers and genetic effects) evaluated over 10,000 years. A cost-effectiveness ratio, was calculated for each alternative standard. This paper describes the alternatives considered and preliminary results of the cost-effectiveness analysis

To develop and validate an image analysis method for quantitative analysis of γ-oryzanol in cold pressed rice bran oil. TLC-densitometric and TLC-image analysis methods were developed, validated, and used for quantitative analysis of γ-oryzanol in cold pressed rice bran oil. The results obtained by these two different quantification methods were compared by paired t-test. Both assays provided good linearity, accuracy, reproducibility and selectivity for determination of γ-oryzanol. The TLC-densitometric and TLC-image analysis methods provided a similar reproducibility, accuracy and selectivity for the quantitative determination of γ-oryzanol in cold pressed rice bran oil. A statistical comparison of the quantitative determinations of γ-oryzanol in samples did not show any statistically significant difference between TLC-densitometric and TLC-image analysis methods. As both methods were found to be equal, they therefore can be used for the determination of γ-oryzanol in cold pressed rice bran oil.

Radioactive hydrogen isotope, tritium is one of the radionuclides which is the most released in the environment during the normal operation of nuclear facilities. The increase of nuclear activities and the development of future generations of reactors, like the EPR and ITER, would lead to a significant increase of tritium effluents in the atmosphere and in the natural waters, thus raising many worries and questions. Aware about the importance of this question, the national association of local information commissions (ANCLI) wished to make a status of the existing knowledge concerning tritium and organized in 2008 a colloquium at Orsay (France) with an inquiring approach. The scientific committee of the ANCLI, renowned for its expertise skills, mobilized several nuclear specialists to carry out this thought. This book represents a comprehensive synthesis of today's knowledge about tritium, about its management and about its impact on the environment and on human health. Based on recent scientific data and on precise examples, it treats of the overall questions raised by this radionuclide: 1 - tritium properties and different sources (natural and anthropic), 2 - the problem of tritiated wastes management; 3 - the bio-availability and bio-kinetics of the different tritium species; 4 - the tritium labelling of environments; 5 - tritium measurement and modeling of its environmental circulation; 6 - tritium radio-toxicity and its biological and health impacts; 7 - the different French and/or international regulations concerning tritium.

Digital dream analysis: a revised method.

Science.gov (United States)

Bulkeley, Kelly

2014-10-01

This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams. A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four "classic" sets of dreams: The male and female "Norm" dreams of Hall and Van de Castle (1966), the "Engine Man" dreams discussed by Hobson (1988), and the "Barb Sanders Baseline 250" dreams examined by Domhoff (2003). A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis. Copyright © 2014 Elsevier Inc. All rights reserved.

Soft Tissue Tumors - Imaging Methods: Imaging methods play an important diagnostic role in soft tissue tumors concerning a preoperative evaluation of localization, size, topographic relationship, dignity, and metastatic disease. The present paper gives an overview about diagnostic methods available today such as ultrasound, thermography, roentgenographic plain films and xeroradiography, radionuclide methods, computed tomography, lymphography, angiography, and magnetic resonance imaging. Besides sonography particularly computed tomography has the most important diagnostic value in soft tissue tumors. The application of a recently developed method, the magnetic resonance imaging, cannot yet be assessed in its significance. (orig.) [de

Application of Stochastic Sensitivity Analysis to Integrated Force Method

X. F. Wei

2012-01-01

Full Text Available As a new formulation in structural analysis, Integrated Force Method has been successfully applied to many structures for civil, mechanical, and aerospace engineering due to the accurate estimate of forces in computation. Right now, it is being further extended to the probabilistic domain. For the assessment of uncertainty effect in system optimization and identification, the probabilistic sensitivity analysis of IFM was further investigated in this study. A set of stochastic sensitivity analysis formulation of Integrated Force Method was developed using the perturbation method. Numerical examples are presented to illustrate its application. Its efficiency and accuracy were also substantiated with direct Monte Carlo simulations and the reliability-based sensitivity method. The numerical algorithm was shown to be readily adaptable to the existing program since the models of stochastic finite element and stochastic design sensitivity are almost identical.

Full Text Available Clustering methods are recently so advanced elaborated algorithms for large collection data analysis that they have been already included today to data mining methods. Clustering methods are nowadays larger and larger group of methods, very quickly evolving and having more and more various applications. In the article, our research concerning usefulness of clustering methods in customer segmentation to manage advertisement campaign is presented. We introduce results obtained by using four selected methods which have been chosen because their peculiarities suggested their applicability to our purposes. One of the analyzed method k-means clustering with random selected initial cluster seeds gave very good results in customer segmentation to manage advertisement campaign and these results were presented in details in the article. In contrast one of the methods (hierarchical average linkage was found useless in customer segmentation. Further investigations concerning benefits of clustering methods in customer segmentation to manage advertisement campaign is worth continuing, particularly that finding solutions in this field can give measurable profits for marketing activity.

The application of laser interferometry in industrial non-destructive testing and material characterization is becoming more prevalent since this method provides non-contact full-field inspection of the test object. However their application only limited to the qualitative analysis, current trend has changed to the development of this method by the introduction of quantitative analysis, which attempts to detail the defect examined. This being the design feature for a ranges of object size to be examined. The growing commercial demand for quantitative analysis for NDT and material characterization is determining the quality of optical and analysis instrument. However very little attention is currently being paid to understanding, quantifying and compensating for the numerous error sources which are a function of interferometers. This paper presents a comparison of measurement analysis using the established theoretical approach and the new approach, taken into account the factor of divergence illumination and other geometrical factors. The difference in the measurement system could be associated in the error factor. (Author)

Comparison of global sensitivity analysis methods – Application to fuel behavior modeling

Energy Technology Data Exchange (ETDEWEB)

Ikonen, Timo, E-mail: timo.ikonen@vtt.fi

2016-02-15

Highlights: • Several global sensitivity analysis methods are compared. • The methods’ applicability to nuclear fuel performance simulations is assessed. • The implications of large input uncertainties and complex models are discussed. • Alternative strategies to perform sensitivity analyses are proposed. - Abstract: Fuel performance codes have two characteristics that make their sensitivity analysis challenging: large uncertainties in input parameters and complex, non-linear and non-additive structure of the models. The complex structure of the code leads to interactions between inputs that show as cross terms in the sensitivity analysis. Due to the large uncertainties of the inputs these interactions are significant, sometimes even dominating the sensitivity analysis. For the same reason, standard linearization techniques do not usually perform well in the analysis of fuel performance codes. More sophisticated methods are typically needed in the analysis. To this end, we compare the performance of several sensitivity analysis methods in the analysis of a steady state FRAPCON simulation. The comparison of importance rankings obtained with the various methods shows that even the simplest methods can be sufficient for the analysis of fuel maximum temperature. However, the analysis of the gap conductance requires more powerful methods that take into account the interactions of the inputs. In some cases, moment-independent methods are needed. We also investigate the computational cost of the various methods and present recommendations as to which methods to use in the analysis.

Full Text Available A green transportation system composed of transit, busses and bicycles could be a significant in alleviating traffic congestion. However, the inaccuracy of current transit ridership forecasting methods is imposing a negative impact on the development of urban transit systems. Traffic Analysis Zone (TAZ delineating is a fundamental and essential step in ridership forecasting, existing delineating method in four-step models have some problems in reflecting the travel characteristics of urban transit. This paper aims to come up with a Transit Traffic Analysis Zone delineation method as supplement of traditional TAZs in transit service analysis. The deficiencies of current TAZ delineating methods were analyzed, and the requirements of Transit Traffic Analysis Zone (TTAZ were summarized. Considering these requirements, Thiessen Polygon was introduced into TTAZ delineating. In order to validate its feasibility, Beijing was then taken as an example to delineate TTAZs, followed by a spatial analysis of office buildings within a TTAZ and transit station departure passengers. Analysis result shows that the TTAZs based on Thiessen polygon could reflect the transit travel characteristic and is of in-depth research value.

Halász Amadé

2015-12-01

Full Text Available Computer-aided colour analysis can facilitate cyclostratigraphic studies. Here we report on a case study involving the development of a digital colour analysis method for examination of the Boda Claystone Formation which is the most suitable in Hungary for the disposal of high-level radioactive waste. Rock type colours are reddish brown or brownish red, or any shade between brown and red. The method presented here could be used to differentiate similar colours and to identify gradual transitions between these; the latter are of great importance in a cyclostratigraphic analysis of the succession. Geophysical well-logging has demonstrated the existence of characteristic cyclic units, as detected by colour and natural gamma. Based on our research, colour, natural gamma and lithology correlate well. For core Ib-4, these features reveal the presence of orderly cycles with thicknesses of roughly 0.64 to 13 metres. Once the core has been scanned, this is a time- and cost-effective method.

The ultimate goals of this research are to cultivate the capability of accurate 551 analysis and to develop the effective soil-structure interaction analysis method and computer program by comparing analysis results obtained in Lotung/Hualien lS5T project. In this research, the scope of this study is to establish the method of soil-structure interaction analysis using hyperlement and to develop a computer program of 551 analysis, to do parametric study for the comprehension of the characteristics and the applicability of hyper elements and to verify the validity and the applicability of this method(or program) through the analysis of seismic response of Hualien lS5T project. In this study, we verified the validity and the efficiency of the soil-structure interaction analysis method using hyper elements and developed computer programs using hyper elements. Based on the I-dimensional wave propagation theory, we developed a computer program of free-field analysis considering the primary non-lineriry of seismic responses. And using this program, we computed the effective ground earthquake motions of soil regions. The computer programs using hyper elements can treat non-homogeneity of soil regions very easily and perform the analysis quickly by the usage of the analytical solutions in horizontal direction. 50 this method would be very efficient and practical method

Design Analysis Method for Multidisciplinary Complex Product using SysML

Directory of Open Access Journals (Sweden)

Liu Jihong

2017-01-01

Full Text Available In the design of multidisciplinary complex products, model-based systems engineering methods are widely used. However, the methodologies only contain only modeling order and simple analysis steps, and lack integrated design analysis methods supporting the whole process. In order to solve the problem, a conceptual design analysis method with integrating modern design methods has been proposed. First, based on the requirement analysis of the quantization matrix, the user’s needs are quantitatively evaluated and translated to system requirements. Then, by the function decomposition of the function knowledge base, the total function is semi-automatically decomposed into the predefined atomic function. The function is matched into predefined structure through the behaviour layer using function-structure mapping based on the interface matching. Finally based on design structure matrix (DSM, the structure reorganization is completed. The process of analysis is implemented with SysML, and illustrated through an aircraft air conditioning system for the system validation.

A new hydrogen-removal method of aluminum melt, spray degassing, is presented. The thermodynamic and kinetic analysis of the method are discussed. A comparison between the thermodynamics and kinetics of the spray degassing method and rotary impellor degassing method is made. The thermodynamic analysis shows that the relationship between the final hydrogen content of the aluminum melt and the ratio of purge gas flow rate to melt flow rate is linear. The result of thermodynamic calculation shows that, in spray degassing, when the ratio of G/q is larger than 2.2 x 10 -6 , the final hydrogen content will be less than 0.1 ml/100 g Al. From the kinetic analysis, the degassing effect is affected by both the size of melt droplets and the time that melt droplets move from sprayer to the bottom of the treatment tank. In numerical calculation, the hydrogen in aluminum melt can be degassed to 0.05 ml/100 g Al from 0.2 ml/100 g Al in 0.02 s with the spray degassing method. Finally, the water-model experiments are presented with the spray degassing method and rotary impellor degassing method. Melt experiments are also presented. Both the water-model experiments and the melt experiments show that the degassing effect of the spray degassing method is better than that of the rotary impeller method

Cost–benefit analysis method for building solutions

International Nuclear Information System (INIS)

Araújo, Catarina; Almeida, Manuela; Bragança, Luís; Barbosa, José Amarilio

2016-01-01

Highlights: • A new cost–benefit method was developed to compare building solutions. • The method considers energy performance, life cycle costs and investment willingness. • The graphical analysis helps stakeholders to easily compare building solutions. • The method was applied to a case study showing consistency and feasibility. - Abstract: The building sector is responsible for consuming approximately 40% of the final energy in Europe. However, more than 50% of this consumption can be reduced through energy-efficient measures. Our society is facing not only a severe and unprecedented environmental crisis but also an economic crisis of similar magnitude. In light of this, EU has developed legislation promoting the use of the Cost-Optimal (CO) method in order to improve building energy efficiency, in which selection criteria is based on life cycle costs. Nevertheless, studies show that the implementation of energy-efficient solutions is far from ideal. Therefore, it is very important to analyse the reasons for this gap between theory and implementation as well as improve selection methods. This study aims to develop a methodology based on a cost-effectiveness analysis, which can be seen as an improvement to the CO method as it considers the investment willingness of stakeholders in the selection process of energy-efficient solutions. The method uses a simple graphical display in which the stakeholders’ investment willingness is identified as the slope of a reference line, allowing easy selection between building solutions. This method will lead to the selection of more desired – from stakeholders’ point of view – and more energy-efficient solutions than those selected through the CO method.

Estekanchi, H.E.; Vafai, A.; Sadeghazar, M.

2004-01-01

In this paper, a new method for performance based earthquake analysis and design has been introduced. In this method, the structure is subjected to accelerograms that impose increasing dynamic demand on the structure with time. Specified damage indexes are monitored up to the collapse level or other performance limit that defines the endurance limit point for the structure. Also, a method for generating standard intensifying accelerograms has been described. Three accelerograms have been generated using this method. Furthermore, the concept of Endurance Time has been described by applying these accelerograms to single and multi degree of freedom linear systems. The application of this method for analysis of complex nonlinear systems has been explained. Endurance Time method provides a uniform approach to seismic analysis and design of complex structures that can be applied in numerical and experimental investigations

The paper shows some of these methods, respectively: variance analysis, covariance analysis, segmentation and discriminant analysis with the mention - for every method – of applicability area for marketing research.

Advances in probabilistic risk analysis

International Nuclear Information System (INIS)

Hardung von Hardung, H.

1982-01-01

Probabilistic risk analysis can now look back upon almost a quarter century of intensive development. The early studies, whose methods and results are still referred to occasionally, however, only permitted rough estimates to be made of the probabilities of recognizable accident scenarios, failing to provide a method which could have served as a reference base in calculating the overall risk associated with nuclear power plants. The first truly solid attempt was the Rasmussen Study and, partly based on it, the German Risk Study. In those studies, probabilistic risk analysis has been given a much more precise basis. However, new methodologies have been developed in the meantime, which allow much more informative risk studies to be carried out. They have been found to be valuable tools for management decisions with respect to backfitting, reinforcement and risk limitation. Today they are mainly applied by specialized private consultants and have already found widespread application especially in the USA. (orig.) [de

Lag profile inversion method for EISCAT data analysis

Directory of Open Access Journals (Sweden)

I. I. Virtanen

2008-03-01

Full Text Available The present standard EISCAT incoherent scatter experiments are based on alternating codes that are decoded in power domain by simple summation and subtraction operations. The signal is first digitised and then different lagged products are calculated and decoded in real time. Only the decoded lagged products are saved for further analysis so that both the original data samples and the undecoded lagged products are lost. A fit of plasma parameters can be later performed using the recorded lagged products. In this paper we describe a different analysis method, which makes use of statistical inversion in removing range ambiguities from the lag profiles. An analysis program carrying out both the lag profile inversion and the fit of the plasma parameters has been constructed. Because recording the received signal itself instead of the lagged products allows very flexible data analysis, the program is constructed to use raw data, i.e. IQ-sampled signal recorded from an IF stage of the radar. The program is now capable of analysing standard alternating-coded EISCAT experiments as well as experiments with any other kind of radar modulation if raw data is available. The program calculates the ambiguous lag profiles and is capable of inverting them as such but, for analysis in real time, time integration is needed before inversion. We demonstrate the method using alternating code experiments in the EISCAT UHF radar and specific hardware connected to the second IF stage of the receiver. This method produces a data stream of complex samples, which are stored for later processing. The raw data is analysed with lag profile inversion and the results are compared to those given by the standard method.

Annular dispersed flow analysis model by Lagrangian method and liquid film cell method

International Nuclear Information System (INIS)

Matsuura, K.; Kuchinishi, M.; Kataoka, I.; Serizawa, A.

2003-01-01

A new annular dispersed flow analysis model was developed. In this model, both droplet behavior and liquid film behavior were simultaneously analyzed. Droplet behavior in turbulent flow was analyzed by the Lagrangian method with refined stochastic model. On the other hand, liquid film behavior was simulated by the boundary condition of moving rough wall and liquid film cell model, which was used to estimate liquid film flow rate. The height of moving rough wall was estimated by disturbance wave height correlation. In each liquid film cell, liquid film flow rate was calculated by considering droplet deposition and entrainment flow rate. Droplet deposition flow rate was calculated by Lagrangian method and entrainment flow rate was calculated by entrainment correlation. For the verification of moving rough wall model, turbulent flow analysis results under the annular flow condition were compared with the experimental data. Agreement between analysis results and experimental results were fairly good. Furthermore annular dispersed flow experiments were analyzed, in order to verify droplet behavior model and the liquid film cell model. The experimental results of radial distribution of droplet mass flux were compared with analysis results. The agreement was good under low liquid flow rate condition and poor under high liquid flow rate condition. But by modifying entrainment rate correlation, the agreement become good even under high liquid flow rate. This means that basic analysis method of droplet and liquid film behavior was right. In future work, verification calculation should be carried out under different experimental condition and entrainment ratio correlation also should be corrected

The ATR and support facilities along with an overview of current programs will be reviewed, but the main focus of the presentation will be on the impact that today's economic and regulatory concerns have had on the operation of this test reactor. Today's economic and regulatory concerns have demanded more work be completed at lower cost while increasing the margin of safety. By the beginning of the 1990 s, federal budgets for research generally and particularly for nuclear research had decreased dramatically. Many national needs continued to require testing in the ATR; but demanded lower cost, increased efficiency, improved performance, and an increased margin of safety. At the same time budgets were decreasing, there was an increase in regulatory compliance activity. The new standards imposed higher margins of safety. The new era of greater openness and higher safety standards complemented research demands to work safer, smarter and more efficiently. Several changes were made at the ATR to meet the demands of the sponsors and public. Such changes included some workforce reductions, securing additional program sponsors, upgrading some facilities, dismantling other facilities, and implementing new safety programs. (author)

Audio information plays a rather important role in the increasing digital content that is available today, resulting in a need for methodologies that automatically analyze such content: audio event recognition for home automations and surveillance systems, speech recognition, music information retrieval, multimodal analysis (e.g. audio-visual analysis of online videos for content-based recommendation), etc. This paper presents pyAudioAnalysis, an open-source Python library that provides a wide range of audio analysis procedures including: feature extraction, classification of audio signals, supervised and unsupervised segmentation and content visualization. pyAudioAnalysis is licensed under the Apache License and is available at GitHub (https://github.com/tyiannak/pyAudioAnalysis/). Here we present the theoretical background behind the wide range of the implemented methodologies, along with evaluation metrics for some of the methods. pyAudioAnalysis has been already used in several audio analysis research applications: smart-home functionalities through audio event detection, speech emotion recognition, depression classification based on audio-visual features, music segmentation, multimodal content-based movie recommendation and health applications (e.g. monitoring eating habits). The feedback provided from all these particular audio applications has led to practical enhancement of the library.

Beyond perturbation introduction to the homotopy analysis method

Solving nonlinear problems is inherently difficult, and the stronger the nonlinearity, the more intractable solutions become. Analytic approximations often break down as nonlinearity becomes strong, and even perturbation approximations are valid only for problems with weak nonlinearity.This book introduces a powerful new analytic method for nonlinear problems-homotopy analysis-that remains valid even with strong nonlinearity. In Part I, the author starts with a very simple example, then presents the basic ideas, detailed procedures, and the advantages (and limitations) of homotopy analysis. Part II illustrates the application of homotopy analysis to many interesting nonlinear problems. These range from simple bifurcations of a nonlinear boundary-value problem to the Thomas-Fermi atom model, Volterra''s population model, Von Kármán swirling viscous flow, and nonlinear progressive waves in deep water.Although the homotopy analysis method has been verified in a number of prestigious journals, it has yet to be ...

Paired comparisons analysis: an axiomatic approach to ranking methods

In this paper we present an axiomatic analysis of several ranking methods for general tournaments. We find that the ranking method obtained by applying maximum likelihood to the (Zermelo-)Bradley-Terry model, the most common method in statistics and psychology, is one of the ranking methods that

Information and meaning revisiting Shannon's theory of communication and extending it to address todays technical problems.

This paper has three goals. The first is to review Shannon's theory of information and the subsequent advances leading to today's statistics-based text analysis algorithms, showing that the semantics of the text is neglected. The second goal is to propose an extension of Shannon's original model that can take into account semantics, where the 'semantics' of a message is understood in terms of the intended or actual changes on the recipient of a message. The third goal is to propose several lines of research that naturally fall out of the proposed model. Each computational approach to solving some problem rests on an underlying model or set of models that describe how key phenomena in the real world are represented and how they are manipulated. These models are both liberating and constraining. They are liberating in that they suggest a path of development for new tools and algorithms. They are constraining in that they intentionally ignore other potential paths of development. Modern statistical-based text analysis algorithms have a specific intellectual history and set of underlying models rooted in Shannon's theory of communication. For Shannon, language is treated as a stochastic generator of symbol sequences. Shannon himself, subsequently Weaver, and at least one of his predecessors are all explicit in their decision to exclude semantics from their models. This rejection of semantics as 'irrelevant to the engineering problem' is elegant and combined with developments particularly by Salton and subsequently by Latent Semantic Analysis, has led to a whole collection of powerful algorithms and an industry for data mining technologies. However, the kinds of problems currently facing us go beyond what can be accounted for by this stochastic model. Today's problems increasingly focus on the semantics of specific pieces of information. And although progress is being made with the old models, it seems natural to develop or

[Poliomyelitis in Landsteiner's time and today].

At a meeting of the Royal and Imperial Association of Physicians in Vienna on December 18, 1908 Dr. Karl Landsteiner reported on the successful experimental transmission of poliomyelitis from man to ape in a study which he undertook together with Erwin Popper. In a scientific article that was published shortly after the meeting, Landsteiner wrote that "the poliomyelitis virus belongs to the group of filterable micro-organisms". Soon, Landsteiner's results were confirmed by other colleagues. During a congress in Washington 1912 Landsteiner declared that the development of a vaccine against poliomyelitis might prove difficult but was certainly possible in his opinion. It took another 45 years before the first polio vaccine was available (1955 Salk) and another 5 years until the oral vaccine (1960 Sabin) was implemented. The incidence of poliomyelitis decreased dramatically in industrial countries as a result of vaccination. Today, poliomyelitis is still an enormous threat in developing countries. Together with many national and international institutions the WHO fights this situation very hard by means of vaccination campaigns. The incidence of side effects and insufficient reactions is small with both vaccines. New techniques in the field of molecular biology and a good knowledge of the poliovirus make it likely that further improvements on the vaccines which are currently available will take place.

In this Letter, we apply the homotopy analysis method to differential-difference equations. We take the discrete KdV equation as an example, and successfully obtain double periodic wave solutions and solitary wave solutions. It illustrates the validity and the great potential of the homotopy analysis method in solving discrete KdV equation. Comparisons are made between the results of the proposed method and exact solutions. The results reveal that the proposed method is very effective and convenient

Statistical trend analysis methods for temporal phenomena

We consider point events occurring in a random way in time. In many applications the pattern of occurrence is of intrinsic interest as indicating a trend or some other systematic feature in the rate of occurrence. The purpose of this report is to survey briefly different statistical trend analysis methods and illustrate their applicability to temporal phenomena in particular. The trend testing of point events is usually seen as the testing of the hypotheses concerning the intensity of the occurrence of events. When the intensity function is parametrized, the testing of trend is a typical parametric testing problem. In industrial applications the operational experience generally does not suggest any specified model and method in advance. Therefore, and particularly, if the Poisson process assumption is very questionable, it is desirable to apply tests that are valid for a wide variety of possible processes. The alternative approach for trend testing is to use some non-parametric procedure. In this report we have presented four non-parametric tests: The Cox-Stuart test, the Wilcoxon signed ranks test, the Mann test, and the exponential ordered scores test. In addition to the classical parametric and non-parametric approaches we have also considered the Bayesian trend analysis. First we discuss a Bayesian model, which is based on a power law intensity model. The Bayesian statistical inferences are based on the analysis of the posterior distribution of the trend parameters, and the probability of trend is immediately seen from these distributions. We applied some of the methods discussed in an example case. It should be noted, that this report is a feasibility study rather than a scientific evaluation of statistical methods, and the examples can only be seen as demonstrations of the methods. 14 refs, 10 figs.
