    Writing a good thesis provides a successful foundation for composing an essay. Teaching how to do that, however, is quite another matter. Teachers often say to students, "Find a thesis," or "Get a thesis," or "Bring in a thesis statement tomorrow," as if students could order one like a pizza, command it like a pet pooch, or grasp one out of thin…

  4. The tractable cognition thesis.

    Science.gov (United States)

    Van Rooij, Iris

    2008-09-01

    The recognition that human minds/brains are finite systems with limited resources for computation has led some researchers to advance the Tractable Cognition thesis: Human cognitive capacities are constrained by computational tractability. This thesis, if true, serves cognitive psychology by constraining the space of computational-level theories of cognition. To utilize this constraint, a precise and workable definition of "computational tractability" is needed. Following computer science tradition, many cognitive scientists and psychologists define computational tractability as polynomial-time computability, leading to the P-Cognition thesis. This article explains how and why the P-Cognition thesis may be overly restrictive, risking the exclusion of veridical computational-level theories from scientific investigation. An argument is made to replace the P-Cognition thesis by the FPT-Cognition thesis as an alternative formalization of the Tractable Cognition thesis (here, FPT stands for fixed-parameter tractable). Possible objections to the Tractable Cognition thesis, and its proposed formalization, are discussed, and existing misconceptions are clarified. 2008 Cognitive Science Society, Inc.

    2017-01-01

    The unobservability thesis (UT) states that the mental states of other people are unobservable. Both defenders and critics of UT seem to assume that UT has important implications for the mindreading debate. Roughly, the former argue that because UT is true, mindreaders need to infer the mental...... implications for the mindreading debate. On the other line of interpretation, UT may matter to the mindreading debate, in particular if we think of it as a thesis about the possible contents of perceptual experience. The upshot is that those who believe UT has implications for the mindreading debate need...... to be more specific about how they understand the thesis....

    Conduction of thesis by the students is one of their major academic activities. Thesis quality and acquired experiences are highly dependent on the supervision. Our study is aimed at identifing the challenges in thesis supervision from both students and faculty members point of view. This study was conducted using individual in-depth interviews and Focus Group Discussions (FGD). The participants were 43 students and faculty members selected by purposive sampling. It was carried out in Tehran University of Medical Sciences in 2012. Data analysis was done concurrently with data gathering using content analysis method. Our data analysis resulted in 162 codes, 17 subcategories and 4 major categories, "supervisory knowledge and skills", "atmosphere", "bylaws and regulations relating to supervision" and "monitoring and evaluation". This study showed that more attention and planning in needed for modifying related rules and regulations, qualitative and quantitative improvement in mentorship training, research atmosphere improvement and effective monitoring and evaluation in supervisory area.

    The majority of medical graduates in Germany complete a doctorate, even though a doctoral degree is not necessary for the practice of medicine. So far, little is known about doctoral candidates' view on the individual benefit a doctoral thesis has for them. Consequently, this is the subject of the present investigation. Data from surveys with graduates of the five medical faculties of Baden-Württemberg from the graduation years 2007/2008 (N=514) and 2010/2011 (N=598) were analysed. One and a half years after graduating 53% of those interviewed had completed their doctorate. When asked about their motivation for writing a doctoral thesis, participants answered most frequently "a doctorate is usual" (85%) and "improvement of job opportunities" (75%), 36% said that an academic career has been their primary motive. Less than 10% responded that they used their doctoral thesis as a means to apply for a job. The proportion of graduates working in health care is equally large among those who have completed a thesis and those who have not. Graduates who pursued a thesis due to scientific interest are also currently more interested in an academic career and recognise more opportunities for research. An implicit benefit of a medical thesis emerged with regard to the self-assessment of scientific competences as those who completed a doctorate rated their scientific competencies higher than those who have not. Although for the majority of physicians research interest is not the primary motivation for completing a doctorate, they might nevertheless achieve some academic competencies. For graduates pursuing an academic career the benefit of completing a medical thesis is more obvious.

    Thesis is one of major requirements for student in pursuing their bachelor degree. In fact, finishing the thesis involves a long process including consultation, writing manuscript, conducting the chosen method, seminar scheduling, searching for references, and appraisal process by the board of mentors and examiners. Unfortunately, most of students find it hard to match all the lecturers' free time to sit together in a seminar room in order to examine the thesis. Therefore, seminar scheduling process should be on the top of priority to be solved. Manual mechanism for this task no longer fulfills the need. People in campus including students, staffs, and lecturers demand a system in which all the stakeholders can interact each other and manage the thesis process without conflicting their timetable. A branch of computer science named Management Information System (MIS) could be a breakthrough in dealing with thesis management. This research conduct a method called clustering to distinguish certain categories using mathematics formulas. A system then be developed along with the method to create a well-managed tool in providing some main facilities such as seminar scheduling, consultation and review process, thesis approval, assessment process, and also a reliable database of thesis. The database plays an important role in present and future purposes.

    Full Text Available In the present action learning implementation, twelve action learning sets were conducted over eight years. The action learning sets consisted of students involved in undergraduate engineering research thesis work. The concurrent study accompanying this initiative, investigated the influence of the action learning environment on student approaches to learning and any accompanying academic, learning and personal benefits realised. The influence of preferred learning styles on set function and student adoption of the action learning process were also examined. The action learning environment implemented had a measurable significant positive effect on student academic performance, their ability to cope with the stresses associated with conducting a research thesis, the depth of learning, the development of autonomous learners and student perception of the research thesis experience. The present study acts as an addendum to a smaller scale implementation of this action learning approach, applied to supervision of third and fourth year research projects and theses, published in 2010.

  10. An Examination of the Neural Unreliability Thesis of Autism.

    Science.gov (United States)

    Butler, John S; Molholm, Sophie; Andrade, Gizely N; Foxe, John J

    2017-01-01

    An emerging neuropathological theory of Autism, referred to here as "the neural unreliability thesis," proposes greater variability in moment-to-moment cortical representation of environmental events, such that the system shows general instability in its impulse response function. Leading evidence for this thesis derives from functional neuroimaging, a methodology ill-suited for detailed assessment of sensory transmission dynamics occurring at the millisecond scale. Electrophysiological assessments of this thesis, however, are sparse and unconvincing. We conducted detailed examination of visual and somatosensory evoked activity using high-density electrical mapping in individuals with autism (N = 20) and precisely matched neurotypical controls (N = 20), recording large numbers of trials that allowed for exhaustive time-frequency analyses at the single-trial level. Measures of intertrial coherence and event-related spectral perturbation revealed no convincing evidence for an unreliability account of sensory responsivity in autism. Indeed, results point to robust, highly reproducible response functions marked for their exceedingly close correspondence to those in neurotypical controls. © The Author 2016.

    Writing a Bachelor thesis is the last step in obtaining a university degree. The thesis may be job- or research-orientated, but it must demonstrate certain degree-level competences. Rubrics are a useful way of unifying the assessment criteria. To design a system of rubrics for assessing the competences associated with the Bachelor thesis of a nursing degree, to examine the system's reliability and validity and to analyse results in relation to the final thesis mark. Cross-sectional and psychometric study conducted between 2012 and 2014. Nursing degree at a Spanish university. Twelve tutors who designed the system of rubrics. Students (n = 76) who wrote their Bachelor thesis during the 2013-2014 academic year. After deciding which aspects would be assessed, who would assess them and when, the tutors developed seven rubrics (drafting process, assessment of the written thesis by the supervisor and by a panel, student self-assessment, peer assessment, tutor evaluation of the peer assessment and panel assessment of the viva). We analysed the reliability (inter-rater and internal consistency) and validity (convergent and discriminant) of the rubrics, and also the relationship between the competences assessed and the final thesis mark. All the rubrics had internal consistency coefficients >0.80. The rubric for oral communication skills (viva) yielded inter-rater reliability of 0.95. Factor analysis indicated a unidimensional structure for all but one of the rubrics, the exception being the rubric for peer assessment, which had a two-factor structure. The main competences associated with a good quality Bachelor thesis were written communication skills and the ability to work independently. The assessment system based on seven rubrics is shown to be valid and reliable. Writing a Bachelor thesis requires a range of degree-level competences and it offers nursing students the opportunity to develop their evidence-based practice skills. Copyright © 2018 Elsevier Ltd.

This Thermal Signature Identification System (TheSIS) provides much more detail than conventional narrowband or quasi-static temperature profiling methods. This detail allows us to match components more thoroughly, detect subtle reversible shifts in performance, and investigate the cause of instabilities or irreversible changes. In particular, we create parameterized models of athermal fiber Bragg gratings (FBGs), delay line interferometers (DLIs), and distributed feedback (DFB) lasers, then subject the alternative models to selection via the Akaike Information Criterion (AIC). Detailed pairing of components, e.g. FBGs, is accomplished by means of weighted distance metrics or norms, rather than on the basis of a single parameter, such as center wavelength.

  6. The Lenoir thesis revisited: Blumenbach and Kant.

    Science.gov (United States)

    Zammito, John H

    2012-03-01

    Timothy Lenoir launched the historical study of German life science at the end of the 18th century with the claim that J. F. Blumenbach's approach was shaped by his reception of the philosophy of Immanuel Kant: a 'teleomechanism' that adopted a strictly 'regulative' approach to the character of organisms. It now appears that Lenoir was wrong about Blumenbach's understanding of Kant, for Blumenbach's Bildungstrieb entailed an actual empirical claim. Moreover, he had worked out the decisive contours of his theory and he had exerted his maximal influence on the so-called 'Göttingen School' before 1795, when Lenoir posits the main influence of Kant's thought took hold. This has crucial significance for the historical reconstruction of the German life sciences in the period. The Lenoir thesis can no longer serve as the point of departure for that reconstruction.

    Plant development is well described. However, full understanding of the regulation of processes associated with plant development is still missing. Present author-review of the Dr.Sc. thesis advances our understanding of the regulation of plant development by quantitative proteomics analyses of seed development of soybean, canola, castor, flax, and model plant arabidopsis in control and environmentally challenged environments. The analysis of greenhouse-grown soybean, canola, castor, and arabidospis provided complex characterization of metabolic processes during seed development, for instance, of carbon assimilation into fatty acids. Furthermore, the analyses of soybean and flax grown in Chernobyl area provided in-depth characterization of seed development in radio-contaminated environment. Soybean and flax were altered by radio-contaminated environment in different way. However, these alterations resulted into modifications in seed oil content. Further analyses showed that soybean and flax possess alterations of carbon metabolism in cytoplasm and plastids along with increased activity of photosynthetic apparatus. Our present experiments are focused on further characterization of molecular bases that might be responsible for alterations of seed oil content in Chernobyl grown plants. (author)

    2012-07-01

    The purpose of this study was to determine the future, in terms of scientific publication, of medical thesis (MT) defended in the Medical School of Lille 2 University (MSL2U) between January 1st, 2001 and December 31st, 2007. The collection of MT published as a corresponding scientific article was realized from PubMed(®). For every corresponding article, we determined the journal Impact Factor (IF), the language of publication and the rank of the student and his MT director in the author list. Analyses were also realized according to the group of speciality of the TM. In all, 11.3% of the 2150 MT defended in the MSL2U were followed up by a scientific publication. The average IF was 2.32 with a median at 1.75 and extreme values from 0 to 14.78. Seventy percent of the articles were published in English. The rank of the student was placed before his MT director (2.06 vs. 3.15). The MT defended by students in the field of medical specialities presented the highest rate of publication (25.1%). The general medicine was the second speciality the most productive in term of number of published articles (n=49) after medical specialities (n=103). The MT director and the PhD students must be more motivated to publish their results. The value of 11.3% could be considered as weak but, because of a huge lack of references, it is impossible to compare our results to those of other French medical schools. It remains important to reform the objectives and the modalities of the writing of a MT: should we not have to turn to thesis called "on article"? Copyright © 2012. Published by Elsevier Masson SAS.

    The bachelor thesis, a final year subject to obtain a nursing degree, presents an ideal opportunity for the development and assessment of professional competencies. Thus, it is necessary to specify that the structure of the bachelor thesis works as an element of review and reflection from both a pedagogical and professional perspective. To analyse the main elements of the bachelor thesis in the nursing degree 2015-16 in Spain. A transversal descriptive study was conducted using a quantitative documentary analysis via study guides or grade reports. The variables were the main academic elements of the bachelor thesis subject (credits, competencies, learning outcomes, contents, methodologies, training activities and assessment). A probabilistic sample of 66 institutions was studied using descriptive statistics with statistical measures of central tendency and measures of variability. The results showed a maximum range of 12 and a minimum of 6 European Credit Transfer and Accumulation System. The definition and number of competencies to be developed varied and the learning outcomes were formulated in only 40.9% of the guides consulted. The most widely used teaching methodologies and training activities were academic supervision (87.9%) and autonomous work (80.3%). Regarding types of work, basic investigation (34.8%), care plans (33.3%) and literature review (30,3%) ranked highest. No specific descriptors could be linked to the contents. Finally, two main assessment tools were found: process and product. The rubric is presented as a main element of the assessment. The bachelor thesis is conceived as autonomous, personal and original academic work. But no homogeneity was observed in the key development elements such as competencies, teaching strategies, or type of bachelor thesis. Therefore, the findings from the analysis and the bibliographic review are presented as recommendations as regards the outcome, structure and/or teaching elements linked to the bachelor thesis

  10. The Forman Thesis: 40 Years After

    Science.gov (United States)

    Carson, Cathryn; Kojevnikov, Alexei; Trischler, Helmuth

    Forty years ago, in 1971, Paul Forman published Weimar Culture, Causality, and Quantum Theory, 1918-1927: Adaptation by German Physicists and Mathematicians to a Hostile Intellectual Environment. His landmark study (too long, too thorough and too fundamental to be called simply an article) became immediately famous, and famously controversial. It has remained at the heart of debates about the historical relationship between science and culture ever since. The controversy surrounding the Forman Thesis was practically unavoidable, for Forman's work put forward and placed at the centre of a broader discussion the argument that the cultural values prevalent in a given place and time could influence the results of discipline-bound research, i.e. the very content of scientific knowledge. This idea, if still controversial, has since become commonly used in cultural studies of science, but at the time of its introduction it created uproar as it explicitly contradicted generally accepted and cherished beliefs about science. Yet tectonic shifts were already underway, if not always visible, that would eventually put those very beliefs into question. The Forman study both reflected and forwarded these shifts in our general perspectives on the nature and practice of science. Despite some heated objections to its findings, Forman's work has fundamentally changed directions of research in the history, sociology and philosophy of science and established itself as a classic in this group of fields, sometimes collectively called science studies. In subsequent decades it has been read and discussed in practically every graduate program that trains students in those fields, circulating in numerous copies and translated into many languages, while the original publication in the journal Historical Studies in the Physical Sciences has long become a bibliographic rarity…

  11. Instructable autonomous agents. Ph.D. Thesis

    Science.gov (United States)

    Huffman, Scott Bradley

    1994-01-01

    In contrast to current intelligent systems, which must be laboriously programmed for each task they are meant to perform, instructable agents can be taught new tasks and associated knowledge. This thesis presents a general theory of learning from tutorial instruction and its use to produce an instructable agent. Tutorial instruction is a particularly powerful form of instruction, because it allows the instructor to communicate whatever kind of knowledge a student needs at whatever point it is needed. To exploit this broad flexibility, however, a tutorable agent must support a full range of interaction with its instructor to learn a full range of knowledge. Thus, unlike most machine learning tasks, which target deep learning of a single kind of knowledge from a single kind of input, tutorability requires a breadth of learning from a broad range of instructional interactions. The theory of learning from tutorial instruction presented here has two parts. First, a computational model of an intelligent agent, the problem space computational model, indicates the types of knowledge that determine an agent's performance, and thus, that should be acquirable via instruction. Second, a learning technique, called situated explanation specifies how the agent learns general knowledge from instruction. The theory is embodied by an implemented agent, Instructo-Soar, built within the Soar architecture. Instructo-Soar is able to learn hierarchies of completely new tasks, to extend task knowledge to apply in new situations, and in fact to acquire every type of knowledge it uses during task performance - control knowledge, knowledge of operators' effects, state inferences, etc. - from interactive natural language instructions. This variety of learning occurs by applying the situated explanation technique to a variety of instructional interactions involving a variety of types of instructions (commands, statements, conditionals, etc.). By taking seriously the requirements of flexible

    2017-12-12

    Systematic reviews (SRs) have been proposed as a type of research methodology that should be acceptable for a graduate research thesis. The aim of this study was to analyse whether PhD theses in European biomedical graduate programs can be partly or entirely based on SRs. In 2016, we surveyed individuals in charge of European PhD programs from 105 institutions. The survey asked about acceptance of SRs as the partial or entire basis for a PhD thesis, their attitude towards such a model for PhD theses, and their knowledge about SR methodology. We received responses from 86 individuals running PhD programs in 68 institutions (institutional response rate of 65%). In 47% of the programs, SRs were an acceptable study design for a PhD thesis. However, only 20% of participants expressed a personal opinion that SRs meet the criteria for a PhD thesis. The most common reasons for not accepting SRs as the basis for PhD theses were that SRs are 'not a result of a PhD candidate's independent work, but more of a team effort' and that SRs 'do not produce enough new knowledge for a dissertation'. The majority of participants were not familiar with basic concepts related to SRs; questions about meta-analyses and the type of plots frequently used in SRs were correctly answered by only one third of the participants. Raising awareness about the importance of SRs and their methodology could contribute to higher acceptance of SRs as a type of research that forms the basis of a PhD thesis.

  3. How to create a journal article from a thesis.

    2012-01-01

    To identify strategies to assist in the publication of research arising from a postgraduate thesis or dissertation. There are many benefits to publishing a journal article from a completed thesis, including contributing knowledge to the writer's chosen field, career enhancement and personal satisfaction. However, there are also numerous obstacles for the newly graduated student in crafting an article fit for a specialist publication from a thesis. The author conducted a search of the title, abstract and keywords of the Cinahl, Scopus and Proquest databases, from 1990 to 2010: The author searched for the words: 'journal article' or 'manuscript; 'thesis' or 'dissertation'. The author excluded papers if: they pertained to allocation of authorship to someone other than the academic adviser; related to undergraduate issues rather than graduate dissertations; were discussions of the merits of a PhD by 'publication' instead of 'by thesis'; were not published in a peer-reviewed journal; or were not in English. The relationship between adviser and student changes as the student becomes a graduate, and new roles for the student and adviser need to be negotiated. Students need to realise that writing a paper from a thesis is usually going to be more difficult than they anticipate, but the application of strategies discussed in this paper should make the task manageable. Furthermore, universities might wish to consider alternatives in which published papers emerge before the examination of a thesis, such as requiring students to write a paper as part of their coursework.

    2008-07-01

    THESIS is a concept for a medium class mission designed for spectroscopic characterization of extrasolar planets between 2-14 microns. The concept leverages off the recent first-steps made by Spitzer and Hubble in characterizing the atmospheres of alien gas giants. Under favourable circumstances, THESIS is capable of identifying biogenic molecules in habitable-zone planets, thereby determining conditions on worlds where life might exist. By systematically characterizing many worlds, from rocky planets to gas-giants, THESIS would deliver transformational science of profound interest to astronomers and the general public.

  5. An evaluation of the process and initial impact of disseminating a nursing e-thesis.

    Macduff, Colin

    2009-05-01

    This paper is a report of a study conducted to evaluate product, process and outcome aspects of the dissemination of a nursing PhD thesis via an open-access electronic institutional repository. Despite the growth of university institutional repositories which make theses easily accessible via the world wide web, nursing has been very slow to evaluate related processes and outcomes. Drawing on Stake's evaluation research methods, a case study design was adopted. The case is described using a four-phase structure within which key aspects of process and impact are reflexively analysed. In the conceptualization/re-conceptualization phase, fundamental questions about the purpose, format and imagined readership for a published nursing PhD were considered. In the preparation phase, seven key practical processes were identified that are likely to be relevant to most e-theses. In the dissemination phase email invitations were primarily used to invite engagement. The evaluation phase involved quantitative indicators of initial impact, such as page viewing and download statistics and qualitative feedback on processes and product. Analysis of process and impact elements of e-thesis dissemination is likely to have more than intrinsic value. The advent of e-theses housed in web-based institutional repositories has the potential to transform thesis access and use. It also offers potential to transform the nature and scope of thesis production and dissemination. Nursing scholars can exploit and evaluate such opportunities.

    2017-02-01

    Full Text Available This descriptive action research focused on the satisfaction of the students on the advising practices of their thesis advisers. The 28 respondents of the study were purposively and incidentally chosen. The findings, derived from the use of unstructured interview and survey questionnaire, revealed that most of the students are satisfied with their thesis advisers in terms of their knowledge of student’s research, professional characteristics and qualities, and personality factors as revealed by the overall weighted mean values of 2.68, 2.72, and 2.72 respectively. The students along thesis advising observed various practices of the faculty members. Students chose their advisers based on their availability, field of specialization, and coaching and mentoring abilities. Based on the findings, this study recommends that the faculty members be given more training to further enhance their abilities in thesis advising. The college may also tap other research-reputable faculty members to become research advisers. An orientation activity among the students may also be conducted to assist them in choosing the faculty member with an appropriate research reputation and also to brief them on the roles they will play as thesis advisers. The need to revisit the policies of the School of Graduate Studies (SGS is also highly recommended. Hence, this study proposes some amendments on the existing guidelines of the department along thesis advising.

    The supervision process is characterized by differences between the supervisors' and the students' expectations before the start of writing a bachelor thesis as well as after its completion. A review of the literature did not reveal any scientifically tested questionnaire for evaluating nursing students' expectations of the supervision process when writing a bachelor thesis. The aim of the study was to determine the construct validity and internal consistency reliability of a questionnaire for measuring nursing students' expectations of the bachelor thesis supervision process. The study had a developmental and methodological design carried out in four steps including construct validity and internal consistency reliability statistical procedures: construction of the items, assessment of face validity, data collection and data analysis. This study was conducted at a university in southern Sweden, where students on the "Nursing student thesis, 15 ECTS" course were consecutively selected for participation. Of the 512 questionnaires distributed, 327 were returned, a response rate of 64%. Five factors with a total variance of 74% and good communalities, ≥0.64, were extracted from the 10-item STQ. The internal consistency of the 10 items was 0.68. The five factors were labelled: The nature of the supervision process, The supervisor's role as a coach, The students' progression to self-support, The interaction between students and supervisor and supervisor competence. A didactic, useful and secure questionnaire measuring nursing students' expectations of the bachelor thesis supervision process based on three main forms of supervision was created.

  13. Rethinking neuroethics in the light of the extended mind thesis.

    Science.gov (United States)

    Levy, Neil

    2007-09-01

    The extended mind thesis is the claim that mental states extend beyond the skulls of the agents whose states they are. This seemingly obscure and bizarre claim has far-reaching implications for neuroethics, I argue. In the first half of this article, I sketch the extended mind thesis and defend it against criticisms. In the second half, I turn to its neuroethical implications. I argue that the extended mind thesis entails the falsity of the claim that interventions into the brain are especially problematic just because they are internal interventions, but that many objections to such interventions rely, at least in part, on this claim. Further, I argue that the thesis alters the focus of neuroethics, away from the question of whether we ought to allow interventions into the mind, and toward the question of which interventions we ought to allow and under what conditions. The extended mind thesis dramatically expands the scope of neuroethics: because interventions into the environment of agents can count as interventions into their minds, decisions concerning such interventions become questions for neuroethics.

    1987-01-01

    Functional Programming (FP) sup BAC87 is an alternative to conventional imperative programming languages. This thesis describes an FP interpreter implementation. Superficially, FP appears to be a simple, but very inefficient language. Its simplicity, however, allows it to be interpreted quickly. Much of the inefficiency can be removed by simple interpreter techniques. This thesis describes the Illinois Functional Programming (IFP) interpreter, an interactive functional programming implementation which runs under both MS-DOS and UNIX. The IFP interpreter allows functions to be created, executed, and debugged in an environment very similar to UNIX. IFP's speed is competitive with other interpreted languages such as BASIC.

  17. Science as an ally of religion: a Muslim appropriation of 'the conflict thesis'.

    Science.gov (United States)

    Yalcinkaya, M Alper

    2011-06-01

    John W. Draper's History of the Conflict between Religion and Science (1874) is commonly regarded as the manifesto of the 'conflict thesis'. The superficiality of this thesis has been demonstrated in recent studies, but to read Draper's work only as a text on 'science versus religion' is to miss half of its significance, as it also involved evaluations of individual religions with respect to their attitudes towards science. Due to Draper's favourable remarks on Islam, the Ottoman author Ahmed Midhat translated his work into Turkish, and published it along with his own comments on Draper's arguments. Midhat interpreted Islam using the cues provided by Draper, and portrayed it as the only religion compatible with science. While his Christian readers condemned Draper for his approach to Islam, Midhat transformed the 'conflict thesis' into a proclamation that Islam and science were allies in opposition to Christian encroachment on the Ottoman Empire. This paper analyses Midhat's appropriation of Draper's work and compares it to the reaction of Draper's Christian readers. It discusses the context that made an alliance between Islam and science so desirable for Midhat, and emphasizes the impact of the historico-geographical context on the encounters between and representations of science and religion.

Data are presented using descriptive statistics, and the χ 2 test served to compare the results among supervisors with the earlier data from the longitudinal survey of doctoral students. Not applicable. This survey is an observational study. Of 3653 potential participants, 1069 (29.3%) supervising 3744 doctoral candidates participated in the study. Supervisors considered themselves to be highly motivated and to offer adequate supervision. On the other hand, 87% stated that they did not feel well prepared for thesis supervision. Supervisors gave lack of timeliness of doctoral students and personal differences (p=0.024 and p=0.001) as the main reasons for terminating thesis projects. Doctoral students predominantly mentioned methodological problems and difficult subjects as critical issues (p=0.001 and pthesis supervisors and medical students feel ill prepared for their roles in the process of a medical dissertation. Contradictory reasons for terminating medical thesis projects based on supervisors' and students' self-assessment suggest a lack of communication and true scientific collaboration between supervisors and doctoral students as the major underlying issue that requires resolution.

    Full Text Available Introduction: The undergraduate thesis rather than a requirement to graduate, are a way of doing research. Previous studies show a thesis published between 2.7% to 17.6% in indexed journals. Objective: Describe the characteristics of the undergraduate thesis of the Faculty of a medical school. Bibliometric study. 221 theses were reviewed, collecting: Year, number of authors, advisers, and references, study population, and national priorities for health research. A search was performed on Google Scholar to assess publication. Descriptive statistics were used. Results: Being lower production in the years 2008-2010 was observed. 91.6% had one advisor, 76% descriptive, 82.8% in hospital population, and 62.4% of adults. Theses displayed between 2010-2014 72.9% did not correspond to any national health research priority. Only 6.8% was based on literature of the last five years. Only 9 (4.1% were published in a scientific journal indexed. Conclusions: The undergraduate thesis were characterized as descriptive, hospital, adults, literature based on outdated and not in line with the national priorities for health research. The publication is low.

    Kusurkar, Rashmi

    2012-08-01

    The aims of this thesis were to gather insights and investigate the factors influencing, outcomes and applications of medical students' motivation. This thesis consists of three literature reviews, four research papers and two application papers. Two research studies investigated the relationships of student motivation with study strategy, effort and academic performance through structural equation modelling and cluster analysis. The relationships of age, maturity, gender and educational background with motivation were investigated through multiple regression analysis. The results of this thesis were 1. Developments in medical education appear to have undervalued student motivation. 2. Motivation is an independent variable in medical education; intrinsic motivation is significantly associated with deep study strategy, high study effort and good academic performance. 3. Motivation is a dependent variable in medical education and is significantly affected by age, maturity, gender, educational background; intrinsic motivation is enhanced by providing students with autonomy, feedback and emotional support. 4. Strength of motivation for medical school can be reliably measured by Strength of Motivation for Medical School questionnaire. The conclusion of this thesis was that it is important to give consideration to motivation in medical education because intrinsic motivation leads to better learning and performance and it can be enhanced through giving students autonomy in learning, feedback about competence and emotional support.

The thesis...... years, knowledge on the use of interior materials and textiles are still rather limited. Contemporary hospital design has been widely criticised of being too institutional and clinical, and one of the main reasons for this experience may be related to the use of ‘cold’, hard-surfaced materials...... of plastic, vinyl and steel. These materials also dominate the new hospitals, designed and constructed these years, and despite the increased focus on the design concept healing architecture, the rational requirements of ef cient cleaning and maintenance still seems to direct the interior design of hospital...

    Full Text Available ABSTRACT. The indigenous education in Brazil has its founding milestone in the first catechetical actions of the Jesuits in the second half of the sixteenth century. In this long trajectory up to the present day the education of the indigenous peoples that inhabit the Brazilian territory has been the subject of controversies and discussions at the governmental and academic levels, which has generated numerous studies. This research had as objective to elaborate a bibliometric panorama of the scientific production on indigenous education present in theses and dissertations of the Brazilian Digital Library of Thesis and Dissertations (BDTD / IBICT through bibliometric methodology. The corpus analyzed was composed of 173 postgraduate studies defended in the country between 1996 and 2016. The results indicate that the Southeast and South regions, respectively, concentrate the largest number of papers and that the Education area is the majority in the Scientific production of the thesis and dissertations recovered.

  18. Feynman's thesis: A new approach to quantum theory

    International Nuclear Information System (INIS)

    Das, Ashok

    2007-01-01

    It is not usual for someone to write a book on someone else's Ph.D. thesis, but then Feynman was not a usual physicist. He was without doubt one of the most original physicists of the twentieth century, who has strongly influenced the developments in quantum field theory through his many ingenious contributions. Path integral approach to quantum theories is one such contribution which pervades almost all areas of physics. What is astonishing is that he developed this idea as a graduate student for his Ph.D. thesis which has been printed, for the first time, in the present book along with two other related articles. The early developments in quantum theory, by Heisenberg and Schroedinger, were based on the Hamiltonian formulation, where one starts with the Hamiltonian description of a classical system and then promotes the classical observables to noncommuting quantum operators. However, Dirac had already stressed in an article in 1932 (this article is also reproduced in the present book) that the Lagrangian is more fundamental than the Hamiltonian, at least from the point of view of relativistic invariance and he wondered how the Lagrangian may enter into the quantum description. He had developed this idea through his 'transformation matrix' theory and had even hinted on how the action of the classical theory may enter such a description. However, although the brief paper by Dirac contained the basic essential ideas, it did not fully develop the idea of a Lagrangian description in detail in the functional language. Feynman, on the other hand, was interested in the electromagnetic interactions of the electron from a completely different point of view rooted in a theory involving action-at-a-distance. His theory (along with John Wheeler) did not have a Hamiltonian description and, in order to quantize such a theory, he needed an alternative formulation of quantum mechanics. When the article by Dirac was brought to his attention, he immediately realized what he was

  20. TCP Packet Trace Analysis. M.S. Thesis

    Science.gov (United States)

    Shepard, Timothy J.

    1991-01-01

    Examination of a trace of packets collected from the network is often the only method available for diagnosing protocol performance problems in computer networks. This thesis explores the use of packet traces to diagnose performance problems of the transport protocol TCP. Unfortunately, manual examination of these traces can be so tedious that effective analysis is not possible. The primary contribution of this thesis is a graphical method of displaying the packet trace which greatly reduce, the tediousness of examining a packet trace. The graphical method is demonstrated by the examination of some packet traces of typical TCP connections. The performance of two different implementations of TCP sending data across a particular network path is compared. Traces many thousands of packets long are used to demonstrate how effectively the graphical method simplifies examination of long complicated traces. In the comparison of the two TCP implementations, the burstiness of the TCP transmitter appeared to be related to the achieved throughput. A method of quantifying this burstiness is presented and its possible relevance to understanding the performance of TCP is discussed.

    Presentation of programs with user interface that can be accessed online through the website of course greatly provide user benefits. User can easily access the program they need. There are usability values that serve as a benchmark for the success of a user accessible program, ie efficiency, effectiveness, and convenience. These usability values also determine the development of the program for the better use. Therefore, on the review title thesis program that will be implemented in STT Dumai was measured usability evaluation. It aims to see which sides are not yet perfect and need to be improved to improve the performance and utilization of the program. Usability evaluation was measured by using smartPLS software. Database used was the result of respondent questionnaires that include questions about the experience when they used program. The result of a review of thesis title program implemented in STT Dumai has an efficiency value of 22.615, the effectiveness of 20.612, and satisfaction of 33.177.

    Sorg, H; Betzler, C; Grieswald, C; Schwab, C G G; Tilkorn, D J; Hauser, J

    2016-06-01

    The postdoctoral lecturer thesis in medicine represents an essential success factor for the career of a physician; however, there is controversial discussion on whether this reflects academic competence or is more a career booster. In this context we conducted a survey among postdoctoral medical lecturers with the aim to evaluate the significance of this qualification. The online survey was performed using a questionnaire requesting biographical parameters and subjective ratings of topics concerning the postdoctoral lecturer thesis. Overall 628 questionnaires were included in the study. The significance of the postdoctoral qualification was rated high in 68.6 % and was seen to be necessary for professional advancement in 71.0 %. The chances of obtaining a full professorship after achieving a postdoctoral qualification were rated moderate to low (68.1 %); nevertheless, 92.3 % would do it again and 86.5 % would recommend it to colleagues. Accordingly, 78.8 % were against its abolishment. Wishes for reforms included standardized federal regulations, reduced dependency on professors and more transparency. The postdoctoral lecturer qualification in medicine is highly valued and the majority of responders did not want it to be abolished. Although the chances for a full professorship were only rated low, successful graduation seems to be beneficial for the career; however, there is a need for substantial structural and international changes.

  3. The functional matrix hypothesis revisited. 3. The genomic thesis.

    Science.gov (United States)

    Moss, M L

    1997-09-01

    Although the initial versions of the functional matrix hypothesis (FMH) theoretically posited the ontogenetic primacy of "function," it is only in recent years that advances in the morphogenetic, engineering, and computer sciences provided an integrated experimental and numerical data base that permitted recent significant revisions of the FMH--revisions that strongly support the primary role of function in craniofacial growth and development. Acknowledging that the currently dominant scientific paradigm suggests that genomic, instead of epigenetic (functional) factors, regulate (cause, control) such growth, an analysis of this continuing controversy was deemed useful. Accordingly the method of dialectical analysis, is employed, stating a thesis, an antithesis, and a resolving synthesis based primarily on an extensive review of the pertinent current literature. This article extensively reviews the genomic hypothesis and offers a critique intended to remove some of the unintentional conceptual obscurantism that has recently come to surround it.

  4. The polarizability of diatomic helium. Ph.D. Thesis

    Science.gov (United States)

    Fortune, P. J.

    1974-01-01

    The calculation of the electric dipole polarizability tensor of the He 2 dimer is described, and the results are used in the computation of several dielectric and optical properties of helium gas, at both high (322 K) and low (4 K) temperatures. The properties considered are the second dielectric virial coefficient, the second Kerr virial coefficient, and the depolarization ratio of the integrated intensities for the Raman scattering experiments. The thesis consists of five parts: the polarizability and various properties are defined; the calculation of the polarizability in the long-range region in terms of a quantum mechanical multipole expansion is described; the calculation of the He2 polarizability in the overlap region via coupled Hartree-Fock perturbation theory is described; the calculation of the quantum pair distribution function for both the He-3 and He-4 isotopes at 4 K is discussed; and the calculated values of the properties of helium gas are given.

  5. The challenge of giving written thesis feedback to nursing students.

    Tuvesson, Hanna; Borglin, Gunilla

    2014-11-01

    Providing effective written feedback on nursing student's assignments can be a challenging task for any assessor. Additionally, as the student groups tend to become larger, written feedback is likely to gain an overall more prominent position than verbal feedback. Lack of formal training or regular discussion in the teaching faculty about the skill set needed to provide written feedback could negatively affect the students' learning abilities. In this brief paper, we discuss written feedback practices, whilst using the Bachelor of Science in Nursing thesis as an example. Our aim is to highlight the importance of an informed understanding of the impact written feedback can have on students. Creating awareness about this can facilitate the development of more strategic and successful written feedback strategies. We end by offering examples of some relatively simple strategies for improving this practice. Copyright © 2014 Elsevier Ltd. All rights reserved.

  6. [Medecine and chemistry in the context of the Enlightenment: the thesis of the Lausanne physician Marc-Louis Vullyamoz].

    Science.gov (United States)

    Terrier, Georges

    2003-01-01

    The chemico-medical essay "De sale lactis essentiali" is a thesis presented in Leyden in 1756 by a physician from Lausanne, M.-L. Vullyamoz, to obtain the medical degree. It shows that chemistry has become a university science connected with medicine and that combustion was explained at that time by G. E. Stahl's theory of the phlogiston. It reminds us that the hypotheses of this German physician, which were part of the animistic doctrine, were widely adopted in Europe. In chemistry they began to fade in 1789 after the publication of Lavoisier's work on oxydation. Nevertheless, they have contributed to establish a modern science. In medicine Stahl's animism evolved towards vitalism, which survived in several forms. Vullyamoz's thesis, which presents chemical experiences intended to analyse and promote a popular medicine, is a testimony of the spirit of Enlightenment, which rejects dogmatism and tries to understand facts through observation and the use of reason.

    2014-01-01

    We surveyed physicians who obtained their medical degree with a thesis in 2011 from the seven medical schools in Lima to know the characteristics of the degree by thesis process, as well as participants’ motivations and perceptions of that process. We included 98 students who did a thesis (87% of total); 99% conducted observational thesis, 30% did so in groups of three. The main motivation was that it was good for their curriculum vitae (94%). At the university where the thesis is compulsory, the process began with the choice of topic and adviser. Perceived “greatest” and “least” difficulty in the process was the completion of administrative procedures (53%) and selection of their advisor (11%), respectively. Administrative timeliness and processes should be reviewed so as not to impede the completion of thesis, since the new University Act requires the completion of a thesis to graduate.

  9. Arnoldus Van Rhijn on aphasia: a forgotten thesis.

    Science.gov (United States)

    Eling, Paul

    2011-01-01

    Aphasia formed a central topic in the discussion on localization of function in the nineteenth century, in particular in France, Germany and Great Brittain. Little is known on contributions from the Netherlands. This paper aims to discuss the contents of Arnoldus Van Rhijn's dissertation on aphasia, written in 1868 and one of the very few Dutch contributions to aphasiology in the nineteenth century. Added to this paper is a translation of the "Physiological Part" of Van Rhijn's dissertation. Van Rhijn discussed three cases with acquired aphasia. He rejected Broca's notion of a cortical center for the articulation of speech and instead regarded the cortex as the site where the will exerted its influence. He argued that there is a certain form of specialization: the will to say something is localized at a different place than the will to write. According to Van Rhijn, the highest motor centers are localized in the subcortical gray areas. Van Rhijn concluded that aphasia may result from lesions to the cortical centers involved in speaking, or from a disconnection of the cortical and subcortical centers. Very little work was done on aphasia in the 19th century in the Netherlands. Van Rhijn's thesis, from an aphasiological point of view of limited value, does show that the notions of "centers", "connections", and "disorders due to disconnections" were generally known before Wernicke, also in the Netherlands.

  10. The History and Significance of the Incommensurability Thesis

    Science.gov (United States)

    Pearce, James Jacob

    The incommensurability thesis (IT) maintains that there are no non-prejudicial means of choosing between competing theories in the empirical sciences. If true, IT would entail that natural science is a fundamentally subjective or irrational activity. Should this latter claim prove justifiable, then empirical science cannot be regarded as an organ of objective knowledge, and "scientific realism" is eo ipso false. I follow the origin of IT from its pre-history in Logical Positivism, through certain preliminary philosophical developments in the work of Karl Popper, W. V. O. Quine, Stephen Toulmin and N. R. Hanson, to the eventual formulation and introduction of IT by Thomas Kuhn and Paul Feyerabend. I then examine the rigorous criticism of IT by various philosophers since about 1964, and discuss different methods of objective theory comparison which have been advanced by such philosophers as Hilary Putnam, W. H. Newton-Smith, Michael Devitt, Hartry Field, Philip Kitcher and Howard Sankey. I conclude by arguing for two counterintuitive claims: (1) Even if true, IT fails to provide evidence against scientific realism. (2) In fact, the truth of IT actually furnishes evidence for a necessary condition for scientific realism, and hence evidence which can be construed as indirectly favorable to scientific realism.

  11. Nozzle Flow with Vibrational Nonequilibrium. Ph.D. Thesis

    Science.gov (United States)

    Landry, John Gary

    1995-01-01

    Flow of nitrogen gas through a converging-diverging nozzle is simulated. The flow is modeled using the Navier-Stokes equations that have been modified for vibrational nonequilibrium. The energy equation is replaced by two equations. One equation accounts for energy effects due to the translational and rotational degrees of freedom, and the other accounts for the affects due to the vibrational degree of freedom. The energy equations are coupled by a relaxation time which measures the time required for the vibrational energy component to equilibrate with the translational and rotational energy components. An improved relaxation time is used in this thesis. The equations are solved numerically using the Steger-Warming flux vector splitting method and the Implicit MacCormack method. The results show that uniform flow is produced outside of the boundary layer. Nonequilibrium exists in both the converging and diverging nozzle sections. The boundary layer region is characterized by a marked increase in translational-rotational temperature. The vibrational temperature remains frozen downstream of the nozzle, except in the boundary layer.

  12. Analysis of the morality of intention in nuclear deterrence, with special reference to final retaliation. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Zink, J.A.

    1990-01-01

    Quite apart from its apparent political obsolescence, the policy of nuclear deterrence is vulnerable to attack for its seemingly obvious immorality. Nuclear war is blatantly immoral, and nuclear deterrence requires a genuine intention to resort to the nuclear retaliation which would precipitate such a war. Therefore, since it is wrong to intend that which is wrong to do, deterrence is immoral. This thesis seeks to examine the nature of the deterrent intention as a means of verifying the soundness of the above deontological argument. This examination is carried out by first suggesting an acceptable notion of intention in general and then, after analysing the views of deterrent intention by other writers, proceeding to demonstrate the uniqueness of that intention. Having done this, and having explored the possibility that deterrence need not contain a genuine intention to retaliate, the thesis moves on to suggest and defend a moral principle which states that endeavours requiring the formation of an immoral intention may nevertheless be moral. Called the Principle of Double Intention (and based on the Principle of Double Effect), it offers a method for the moral assessment of agents who form immoral intentions within larger contexts. By applying this principle to nuclear deterrence, it is demonstrated that agents who undertake such a policy may be morally justified in doing so, provided certain conditions are met. The thesis closes with a refutation of the objection that an agent cannot rationally form an intention (such as that required in deterrence) which he has no reason to carry out.

Specifically, the study attempt to study: firstly, the faculty collaboration network; andsecondly, the degree and nature of inter-disciplinary collaboration, as reflected in the compositionof the thesis committees. A total 751 Master’s theses published by the eight LIS in the periodsfrom 2006 to 2011 were analyzed. Data extracted included the composition of each committeemember-ship and research topics covered in these theses. Furthermore, data about the faculty’sbackground were also collected, including gender, seniority, department affiliation, highest degreereceived, with which the faculty’s degree of interdisciplinary collaboration, as reflected in the thesiscommittee they appeared, could be analyzed. With the theses committee composition data, networksof faculty collaboration were generated where each faulty member were represented by a node,and the strength of their collaboration was represented by the frequency of their co-appeared inthese committees. Various network measures, such as centrality, clustering coefficient, E-I indexwere used to study the cohesion of each department and the LIS filed as a whole. Three diversitymeasures: Shannon, Simpson, and Gini coefficient, were used to assess the degree of interdisciplinarityof each department and faculty. Regression analyses showed that the number of these advised,seniority, and thesis topic diversity were the significant predictor of a faculty’s centrality in the LISnetwork.

    2018-01-01

    Over the course of my career, I have experienced the thesis in different ways. This reflection paper will relay my encounters with, what I am calling, thesis-objects (to borrow a concept from object relations). I encountered the thesis-objects at different phases of my professional development: when I was a student, a supervisor for Smith MSW students, a PhD applicant, and chair of the Alumni Thesis Award Committee. My relationship with each thesis-object has refined me and granted me new perspective and personal growth. When I was a student, the thesis was a coach helping me develop tools to answer important questions. When I was a supervisor, the thesis was a bridge-builder strengthening my relationships with supervisees. Then, when I was a PhD applicant, the thesis was a door-opener providing me means to access PhD opportunities. Now that I am a chair, the thesis is a teacher opening my eyes to new intellectual terrain and pressing social problems. PMID:29479118

This paper reports on a small part of the results of a study in attempting to identify students’ ability and difficulties in writing an English undergraduate thesis in a state university in Indonesia. The paper centres around the students’ ability and difficulties in writing a data presentation and discussion chapter, which are related to critical capacity looked at in this study. The paper begins with a brief introduction, which presents the background and the theories underpinning the study. This will be followed by an account of the methodology, in which it is argued that the study used a case study method, particularly text analysis  and involved  nine theses  selected randomly and analysed based on the elements of a conventional research report and the Transitivity system of systemic functional grammar, developed by Halliday. The paper then delineates the results, showing that despite their  good control in the discourse semantic level, students in general still need a lot of guidance and assistance in writing a data presentation and discussion chapter. Recommendation for further research will conclude the paper. Abstrak: Kemampuan Berpikir Kritis Mahasiswa dalam Menulis Tesis.

    Zilsel's thesis on the artisanal origins of modern science remains one of the most original proposals about the emergence of scientific modernity. We propose to inspect the scientific developments in Iberia in the early modern period using Zilsel's ideas as a guideline. Our purpose is to show that his ideas illuminate the situation in Iberia but also that the Iberian case is a remarkable illustration of Zilsel's thesis. Furthermore, we argue that Zilsel's thesis is essentially a sociological explanation that cannot be applied to isolated cases; its use implies global events that involve extended societies over large periods of time.

    To explore the thesis experience of recent Master of Health Professions Education (MHPE) graduates in the University of Illinois at Chicago (UIC) program. This is a qualitative case study exploring the experience of MHPE graduates between 2014 and 2016 (n=31). Using convenience sampling, all graduates with an email address (n=30) were invited to participate in an online survey and semi-structured interviews. Interviews were completed in-person or via telephone or video conference; interviewers collected detailed notes and audio recordings.  Two authors independently analyzed the data iteratively using thematic analysis and discrepancies were discussed and resolved. Survey results (n=20, 67%) revealed an average graduation of 5.1 years; 10 graduates (33%) were interviewed. Three themes related to the thesis experience were identified: success factors, challenges, and outcomes. Success factors, when present, promoted completion of a thesis; these included: a supportive program environment, time management, available resources, MHPE foundational coursework, aligning theses with career goals, and identifying a project with limited scope. Challenges made thesis completion more difficult for graduates; these included: institutional factors, personal or professional responsibilities, burnout, externally-imposed deadlines, and barriers in the research process. Despite these challenges, completing the thesis resulted in many professional or personal benefits (outcomes). Multiple success factors and challenges were identified in the master's thesis process among MHPE graduates at UIC. These findings can help students conducting education-based scholarship through the master's thesis process. This study also informs program evaluation and improvements and outlines personal and professional outcomes of completing a master's thesis.

    Ensuring achievement of research experience by students is one of the most important goals of the thesis-conduction process and evaluation of student satisfaction with this process is one of the most imperative challenges herein. The aim of this study is to investigate the satisfaction of dental students passing the thesis educational course from the Isfahan Dental School. Sixty-two dental students who had graduated in2011, from the Isfahan Dental School, participated in this descriptive cross-sectional study. The postgraduate Research Experience Questionnaire (PREQ) was used for data collection. The questionnaire evaluated student satisfaction in seven domains: Thesis supervision, skill development, intellectual climate, infrastructure, thesis examination, goals and expectations, and overall satisfaction. The data were analyzed on an SPSS software using descriptive and inferential statistics. The mean score of satisfaction of the participants was 75 ± 12. On the basis of their scores, satisfaction in 3.2% of them was slow, in 33.9%was medium, in 61.3% was good and in 1.6% was high. The highest satisfaction was found to be in thesis supervision and the least was in the intellectual climate domain. There was no significant statistical difference between satisfaction and gender (P = 0.46). Considering the results, to increase student satisfaction for passing the thesis courses, it is necessary to improve the intellectual climate in dental schools and also increase the research budget for more financial support of students to carry out their projects.

    Full Text Available The aquisition of clinical and practical skills is the main target during the speciality training program. On the other hand, acquisition of skills in reading and interpreting scientific knowledge are also important training targets in order to develop and update clinical practice constantly. The process of thesis preparation during the speciality training provides an important opportunity to capture the skills in interpreting scientific knowledge. In Turkey, thesis writing has been obligatory for completion of speciality training for several years. Recently, there has been a discussion about the obligation for clinicians to write a thesis, especially those who are undertaking specialist training in education and research hospitals. The aim of this study was to evaluate the pros and cons of thesis writing during speciality training using a questionnaire that was sent to specialists. This descriptive and analytical study was conducted as an e-questionnaire between December, 2013, and May, 2014. A likert scale consisted of 18 questions has been prepared in accordance with this study. Th e questionnaire was sent to 1536 physicians. 328 of the questionnaires have been included in the study by evaluating the responses obtained from 345 of the participants. Th e response rate was 23%. Th e Cronbach alpha coeff icient was 0.77. Out of the 328 questionnaires, 11.9 %were from Basic Medical Sciences, 57%from Internal Medical Sciences, and 30.2%from Surgical Medical Sciences. Among the respondents, the percentage of specialists, assistant professors, associate professors and professors were 20.7%, 8.2%, 13.7%, and 57.3%, respectively. Independent of specialty field and aff iliation, the respondents concluded that the conduction and thesis writing contributed to their scientific career in spite of the common problems they encountered regarding adequate time for preparation. Furthermore, they concluded that thesis writing had a positive eff ect in the

    Many universities and colleges in low-income and middle-income countries require a masters dissertation or thesis for as part of postgraduate training, and some colleges offer a 1-year to 2-year diploma of child health as a clinical qualification to enable skills in child health for generalists, or as part of the early phase of paediatric training. This paper describes the stages of doing a research project for such a masters or diploma, and describes in detail how to write a minor thesis. The paper is designed to provide a practical approach for junior researchers, and their supervisors. Colleges differ in their formal requirements of a minor thesis (word count, line spacing, referencing style), but this paper outlines the principles and practical issues rarely covered elsewhere. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

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

    1996-08-01

    This report summarizes the papers included as part of a doctoral thesis. It starts with the history of the greenhouse effect and proceeds with the international efforts to control man-made air pollution. In 1990 the UN established the Intergovernmental Negotiation Committee for Climate Change (INC), the task of which was to prepare the negotiations for the UN`s Framework Convention on Climate Change (FCCC), which came into force in 1994. The commitments of the signatories are not legally binding, quantitatively. The FCCC established a Conference of the Parties (COP) as the supreme body of the convention. Its first session was held in Berlin in 1995. The Berlin Mandate established a process that would enable the Parties to take actions for the period after 2000. A possible international climate agreement is often evaluated in terms of its efficiency or cost-effectiveness. Calculations are extremely complex and involve great uncertainties. Countries may not agree on the methods of calculation. There are several studies on cost-benefit analyses for controlling global warming, based on various simplifications. The thesis focuses on the cost-effectiveness of possible climate agreements and covers only CO{sub 2}. The implications of limited participation in a climate agreement are discussed. The design of a climate treaty should take into account how different policy instruments can be used to influence the emissions from non-participants. The final section discusses the impact on cost-effectiveness of a trade able quota system if some counties have market power. 59 refs.

Search for plagiarism in 33 thesis introductions using a Google search algorithm, characterizes of the study type and we search in electronic form if the thesis mentor have published articles in scientific journals. We found evidence of plagiarism in 27/33 introductions, 37.3% (171/479) of all the paragraphs analyzed had some degree of plagiarism, literal plagiarism was the most frequent (20/27) and journals were the most common sources of plagiarism (19/27). The characteristics of the studies were observational (32/33), cross-sectional (30/33), descriptive (25/33) and retrospective (19/33). None of the authors had published in a scientific journal, and only nine of his tutors of them had at least one publication. No association was found between the characteristics of the thesis and the presence of plagiarism. In conclusion, we found a high frequency of plagiarism in theses analyzed. Is responsibility of medical schools take the necessary actions to detect and avoid plagiarism among their students.

  2. The Ethical Justification of the Thesis that Separates Law from Morality Through John Austin

    Directory of Open Access Journals (Sweden)

    Galvão Rabelo

    2015-12-01

    Full Text Available The british legal philosopher John Austin stands at the threshold of the evolution of the legal positivist tradition. His work, which dates back to the first half of the 19th century, was especially important to establish the basic elements of this school of legal understanding. Among his contributions to the legal positivist doctrine, lies the creation of the thesis that separates morality from law. Under an ethical context, however, John Austin was an ardent utilitarian who defended the use of the principle of utility as the only rational criteria for the unveiling of superior moral standards (divine laws. Considering both dimensions of his understanding, it has long been wondered if his utilitarian ethics have influenced, somehow, his legal theory, especially in regards to the separation thesis. Said thesis, which is in the center of the legal positivist tradition, has been interpreted in different ways in contemporary legal debate. A particular branch, called ethical positivism, opened new perspectives to the study of this tradition, defending the legal positivism theory as a morally satisfactory theoretical model for the contemporary legal systems. Hence, using the main premise of ethical positivism (which states that there are moral reasons to defend the separation thesis as an interprative and methodological tool, this paper plans on revisiting the link between John Austins legal and ethical convictions, in order to comprehend what were the moral reasons which led him to defend the separation of what law is and what it should be.

  4. Possible future HERA analyses

    International Nuclear Information System (INIS)

    Geiser, Achim

    2015-12-01

    A variety of possible future analyses of HERA data in the context of the HERA data preservation programme is collected, motivated, and commented. The focus is placed on possible future analyses of the existing ep collider data and their physics scope. Comparisons to the original scope of the HERA pro- gramme are made, and cross references to topics also covered by other participants of the workshop are given. This includes topics on QCD, proton structure, diffraction, jets, hadronic final states, heavy flavours, electroweak physics, and the application of related theory and phenomenology topics like NNLO QCD calculations, low-x related models, nonperturbative QCD aspects, and electroweak radiative corrections. Synergies with other collider programmes are also addressed. In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation. Due to well-established data and MC sets, calibrations, and analysis procedures the manpower and expertise needed for a particular analysis is often very much smaller than that needed for an ongoing experiment. Since centrally funded manpower to carry out such analyses is not available any longer, this contribution not only targets experienced self-funded experimentalists, but also theorists and master-level students who might wish to carry out such an analysis.

    1996-12-31

    The overall objectives of the project `Feasibility of electricity production from biomass by pressurized gasification systems` within the EC Research Programme JOULE II were to evaluate the potential of advanced power production systems based on biomass gasification and to study the technical and economic feasibility of these new processes with different type of biomass feed stocks. This report was prepared as part of this R and D project. The objectives of this task were to perform fuel analyses of potential woody and herbaceous biomasses with specific regard to the gasification properties of the selected feed stocks. The analyses of 15 Scandinavian and European biomass feed stock included density, proximate and ultimate analyses, trace compounds, ash composition and fusion behaviour in oxidizing and reducing atmospheres. The wood-derived fuels, such as whole-tree chips, forest residues, bark and to some extent willow, can be expected to have good gasification properties. Difficulties caused by ash fusion and sintering in straw combustion and gasification are generally known. The ash and alkali metal contents of the European biomasses harvested in Italy resembled those of the Nordic straws, and it is expected that they behave to a great extent as straw in gasification. Any direct relation between the ash fusion behavior (determined according to the standard method) and, for instance, the alkali metal content was not found in the laboratory determinations. A more profound characterisation of the fuels would require gasification experiments in a thermobalance and a PDU (Process development Unit) rig. (orig.) (10 refs.)

  8. Analyses of MHD instabilities

    International Nuclear Information System (INIS)

    Takeda, Tatsuoki

    1985-01-01

    In this article analyses of the MHD stabilities which govern the global behavior of a fusion plasma are described from the viewpoint of the numerical computation. First, we describe the high accuracy calculation of the MHD equilibrium and then the analysis of the linear MHD instability. The former is the basis of the stability analysis and the latter is closely related to the limiting beta value which is a very important theoretical issue of the tokamak research. To attain a stable tokamak plasma with good confinement property it is necessary to control or suppress disruptive instabilities. We, next, describe the nonlinear MHD instabilities which relate with the disruption phenomena. Lastly, we describe vectorization of the MHD codes. The above MHD codes for fusion plasma analyses are relatively simple though very time-consuming and parts of the codes which need a lot of CPU time concentrate on a small portion of the codes, moreover, the codes are usually used by the developers of the codes themselves, which make it comparatively easy to attain a high performance ratio on the vector processor.

  9. Uncertainty Analyses and Strategy

    International Nuclear Information System (INIS)

    Kevin Coppersmith

    2001-01-01

    The DOE identified a variety of uncertainties, arising from different sources, during its assessment of the performance of a potential geologic repository at the Yucca Mountain site. In general, the number and detail of process models developed for the Yucca Mountain site, and the complex coupling among those models, make the direct incorporation of all uncertainties difficult. The DOE has addressed these issues in a number of ways using an approach to uncertainties that is focused on producing a defensible evaluation of the performance of a potential repository. The treatment of uncertainties oriented toward defensible assessments has led to analyses and models with so-called ''conservative'' assumptions and parameter bounds, where conservative implies lower performance than might be demonstrated with a more realistic representation. The varying maturity of the analyses and models, and uneven level of data availability, result in total system level analyses with a mix of realistic and conservative estimates (for both probabilistic representations and single values). That is, some inputs have realistically represented uncertainties, and others are conservatively estimated or bounded. However, this approach is consistent with the ''reasonable assurance'' approach to compliance demonstration, which was called for in the U.S. Nuclear Regulatory Commission's (NRC) proposed 10 CFR Part 63 regulation (64 FR 8640 [DIRS 101680]). A risk analysis that includes conservatism in the inputs will result in conservative risk estimates. Therefore, the approach taken for the Total System Performance Assessment for the Site Recommendation (TSPA-SR) provides a reasonable representation of processes and conservatism for purposes of site recommendation. However, mixing unknown degrees of conservatism in models and parameter representations reduces the transparency of the analysis and makes the development of coherent and consistent probability statements about projected repository

  10. Micromechanical Analyses of Sturzstroms

    Science.gov (United States)

    Imre, Bernd; Laue, Jan; Springman, Sarah M.

    2010-05-01

    Sturzstroms are very fast landslides of very large initial volume. As type features they display extreme run out, pared with intensive fragmentation of the involved blocks of rock within a collisional flow. The inherent danger to the growing communities in alpine valleys below future potential sites of sturzstroms must be examined and results of predictions of endangered zones allow to impact upon the planning processes in these areas. This calls for the ability to make Type A predictions, according to Lambe (1973), which are done before an event. But Type A predictions are only possible if sufficient understanding of the mechanisms involved in a process is available. The motivation of the doctoral thesis research project presented is therefore to reveal the mechanics of sturzstroms in more detail in order to contribute to the development of a Type A run out prediction model. It is obvious that a sturzstrom represents a highly dynamic collisional granular regime. Thus particles do not only collide but will eventually crush each other. Erismann and Abele (2001) describe this process as dynamic disintegration, where kinetic energy is the main driver for fragmenting the rock mass. In this case an approach combining the type features long run out and fragmentation within a single hypothesis is represented by the dynamic fragmentation-spreading model (Davies and McSaveney, 2009; McSaveney and Davies, 2009). Unfortunately, sturzstroms, and fragmentation within sturzstroms, can not be observed directly in a real event because of their long "reoccurrence time" and the obvious difficulties in placing measuring devices within such a rock flow. Therefore, rigorous modelling is required in particular of the transition from static to dynamic behaviour to achieve better knowledge of the mechanics of sturzstroms, and to provide empirical evidence to confirm the dynamic fragmentation-spreading model. Within this study fragmentation and their effects on the mobility of sturzstroms

    (ee'p) experiments allow to measure the missing energy distribution as well as the momentum distribution of the extracted proton in the nucleus versus the missing energy. Such experiments are presently conducted on SACLAY's A.L.S. 300 Linac. Electrons and protons are respectively analysed by two spectrometers and detected in their focal planes. Counting rates are usually low and include time coincidences and accidentals. Signal-to-noise ratio is dependent on the physics of the experiment and the resolution of the coincidence, therefore it is mandatory to get a beam current distribution as flat as possible. Using new technologies has allowed to monitor in real time the behavior of the beam pulse and determine when the duty cycle can be considered as being good with respect to a numerical basis

  12. EEG analyses with SOBI.

    The motivating vision behind Sandia's MENTOR/PAL LDRD project has been that of systems which use real-time psychophysiological data to support and enhance human performance, both individually and of groups. Relevant and significant psychophysiological data being a necessary prerequisite to such systems, this LDRD has focused on identifying and refining such signals. The project has focused in particular on EEG (electroencephalogram) data as a promising candidate signal because it (potentially) provides a broad window on brain activity with relatively low cost and logistical constraints. We report here on two analyses performed on EEG data collected in this project using the SOBI (Second Order Blind Identification) algorithm to identify two independent sources of brain activity: one in the frontal lobe and one in the occipital. The first study looks at directional influences between the two components, while the second study looks at inferring gender based upon the frontal component.

    New technologies for acquisition of genomic data, while offering unprecedented opportunities for genetic discovery, also impose severe burdens of interpretation and penalties for multiple testing. The Pathway-based Analyses Group of the Genetic Analysis Workshop 19 (GAW19) sought reduction of multiple-testing burden through various approaches to aggregation of highdimensional data in pathways informed by prior biological knowledge. Experimental methods testedincluded the use of "synthetic pathways" (random sets of genes) to estimate power and false-positive error rate of methods applied to simulated data; data reduction via independent components analysis, single-nucleotide polymorphism (SNP)-SNP interaction, and use of gene sets to estimate genetic similarity; and general assessment of the efficacy of prior biological knowledge to reduce the dimensionality of complex genomic data. The work of this group explored several promising approaches to managing high-dimensional data, with the caveat that these methods are necessarily constrained by the quality of external bioinformatic annotation.

    When prosecuting crimes, the main question to answer is often who had a motive and the possibility to commit the crime. When investigating cyber crimes, the question of possibility is often hard to answer, as in a networked system almost any location can be accessed from almost anywhere. The most...... common tool to answer this question, analysis of log files, faces the problem that the amount of logged data may be overwhelming. This problems gets even worse in the case of insider attacks, where the attacker’s actions usually will be logged as permissible, standard actions—if they are logged at all....... Recent events have revealed intimate knowledge of surveillance and control systems on the side of the attacker, making it often impossible to deduce the identity of an inside attacker from logged data. In this work we present an approach that analyses the access control configuration to identify the set...

  16. Network class superposition analyses.

    Directory of Open Access Journals (Sweden)

    Carl A B Pearson

    Full Text Available Networks are often used to understand a whole system by modeling the interactions among its pieces. Examples include biomolecules in a cell interacting to provide some primary function, or species in an environment forming a stable community. However, these interactions are often unknown; instead, the pieces' dynamic states are known, and network structure must be inferred. Because observed function may be explained by many different networks (e.g., ≈ 10(30 for the yeast cell cycle process, considering dynamics beyond this primary function means picking a single network or suitable sample: measuring over all networks exhibiting the primary function is computationally infeasible. We circumvent that obstacle by calculating the network class ensemble. We represent the ensemble by a stochastic matrix T, which is a transition-by-transition superposition of the system dynamics for each member of the class. We present concrete results for T derived from boolean time series dynamics on networks obeying the Strong Inhibition rule, by applying T to several traditional questions about network dynamics. We show that the distribution of the number of point attractors can be accurately estimated with T. We show how to generate Derrida plots based on T. We show that T-based Shannon entropy outperforms other methods at selecting experiments to further narrow the network structure. We also outline an experimental test of predictions based on T. We motivate all of these results in terms of a popular molecular biology boolean network model for the yeast cell cycle, but the methods and analyses we introduce are general. We conclude with open questions for T, for example, application to other models, computational considerations when scaling up to larger systems, and other potential analyses.

    Resta, Robert G.; McCarthy Veach, Patricia; Charles, Sarah; Vogel, Kristen; Blase, Terri

    2010-01-01

    Publication of original research, clinical experiences, and critical reviews of literature are vital to the growth of the genetic counseling field, delivery of genetic counseling services, and professional development of genetic counselors. Busy clinical schedules, lack of time and funding, and training that emphasizes clinical skills over research skills may make it difficult for new genetic counselors to turn their thesis projects into publications. This paper summarizes and elaborates upon a presentation aimed at de-mystifying the publishing process given at the 2008 National Society of Genetic Counselors Annual Education Conference. Specific topics include familiarizing prospective authors, particularly genetic counseling students, with the basics of the publication process and related ethical considerations. Former students’ experiences with publishing master’s theses also are described in hopes of encouraging new genetic counselors to submit for publication papers based on their thesis projects.

  19. The new "new racism" thesis: limited government values and race-conscious policy attitudes.

    Science.gov (United States)

    Gainous, Jason

    2012-01-01

    Some contend that Whites’ application of values to form opinions about race-conscious policy may constitute a subtle form of racism. Others challenge the new racism thesis, suggesting that racism and values are exclusive in their influence. Proponents of the thesis assert that many Whites’ attitudes about such policy are structured by a mix of racism and American individualism. The author suggests that an even more subtle form of racism may exist. Racism may actually be expressed in opposition to big government. The test results presented here indicate that the effects of limited-government values on attitudes about race-conscious policy are conditional on levels of racial prejudice for many Whites, whereas the effects on racially ambiguous social welfare policy attitudes are not. The author contends that these results provide support to the argument that racism still exists and has found a new subtle expression.

    Uecker, Jeremy E; Lucke, Glenn

    2011-12-01

    This study instead focuses on culture wars among religious elites-clergy-and tests three aspects of the culture wars thesis: (1) whether cultural wars exist at all among religious elites, (2) whether clergy attitudes are polarized on these issues, and (3) whether religious authority or religious affiliation is more salient in creating culture wars cleavages. Using data from a large random sample of Protestant clergy, we find a substantial amount of engagement in culture wars by all types of Protestant clergy. The amount of polarization is more attributable to views of religious authority (i.e., biblical inerrancy) than to religious tradition. Moreover, polarization among clergy is somewhat more evident on culture wars issues than on other social and political issues. These findings are generally supportive of the culture wars thesis and should help return examinations of culture wars back to where they were originally theorized to be waged: among elites.

    2017-08-01

    Full Text Available The aim of this paper is to study the Jürgen Habermas´s vision of genetic manipulation; in particular, it will be addressed critically his assumption that the genetically engineered person would loose his awareness of authorship. In the author´s view, positive genetic intervention —one that is to genetically enhance the subject— would eliminate the awareness of authorship of that subject, as well as his self-understanding as moral agent. Two aspects of the question will be approached: firstly, the correctness or incorrectness of Habermas´s thesis. Secondly, the relevance of the thesis to oppose positive eugenics. Could be other arguments considered within Habermas´s conceptual framework to oppose positive eugenics?

  2. The denial of death thesis: sociological critique and implications for palliative care.

    Science.gov (United States)

    Zimmermann, Camilla; Rodin, Gary

    2004-03-01

    It has become commonplace to say that contemporary western society is 'death-denying'. This characterization, which sociologists have termed the 'denial of death thesis', first arose in the social science, psychological and clinical medical literature in the period between 1955 and 1985. During the same time period, the hospice and palliative care movements were developing and in part directed themselves against the perceived cultural denial of death in western society. While the denial of death has been taken for granted by the lay public as well as by clinicians, in the sociological literature it has been increasingly questioned. In this paper we use sociological critiques of the denial of death thesis to raise critical questions about the theory and practice of contemporary palliative care. In particular, we argue that the emphasis of palliative care should not be on extinguishing the denial of death but on the relief of suffering.

  9. Increasing the number of feminist scientists: why feminist aims are not served by the Underdetermination Thesis

    Science.gov (United States)

    Intemann, Kristen

    2008-11-01

    Recent feminist philosophers of science have argued that feminist values can contribute to rational decisions about which scientific theories to accept. On this view, increasing the number of feminist scientists is important for ensuring rational and objective theory acceptance. The Underdetermination Thesis has played a key role in arguments for this view [Anderson (1995) Hypatia 10(3), 50 84; Hankinson Nelson (1990) Who knows? From Quine to a feminist empiricism. Temple University Press, Philadelphia; Longino (1990) Science as social knowledge. Princeton University Press, Princeton; Longino (2002) The fate of knowledge. Princeton University Press, Princeton; Kourany (2003) Philosophy of Science 70, 1 14]. This thesis is alleged to open an argumentative “gap” between evidence and theory acceptance and provide a rationale for filling the gap with feminist values. While I agree with the conclusion that feminist values can contribute to rational decisions about which theories to accept, I argue that the Underdetermination Thesis cannot support this claim. First, using earlier arguments [Laudan (1990) in: R. Giere (ed) Minnesota studies in the philosophy of science, vol 14, pp 267 297; Slezak (1991) International Studies in Philosophy of Science 5, 241 256; Pinnick (1994) Philosophy of Science 61, 664 657] I show that Underdetermination cannot, by itself, establish that feminist values should fill the gap in theory acceptance. Secondly, I argue that the very use of the Underdetermination Thesis concedes that feminist values are extra-scientific, a-rational, factors in theory acceptance. This concession denies feminists grounds to explain why their values contribute to rational scientific reasoning. Finally, I propose two alternative ways to explain how feminist values can contribute to rational theory acceptance that do not rely on Underdetermination.

  13. Seismic fragility analyses

    International Nuclear Information System (INIS)

    Kostov, Marin

    2000-01-01

    In the last two decades there is increasing number of probabilistic seismic risk assessments performed. The basic ideas of the procedure for performing a Probabilistic Safety Analysis (PSA) of critical structures (NUREG/CR-2300, 1983) could be used also for normal industrial and residential buildings, dams or other structures. The general formulation of the risk assessment procedure applied in this investigation is presented in Franzini, et al., 1984. The probability of failure of a structure for an expected lifetime (for example 50 years) can be obtained from the annual frequency of failure, β E determined by the relation: β E ∫[d[β(x)]/dx]P(flx)dx. β(x) is the annual frequency of exceedance of load level x (for example, the variable x may be peak ground acceleration), P(fI x) is the conditional probability of structure failure at a given seismic load level x. The problem leads to the assessment of the seismic hazard β(x) and the fragility P(fl x). The seismic hazard curves are obtained by the probabilistic seismic hazard analysis. The fragility curves are obtained after the response of the structure is defined as probabilistic and its capacity and the associated uncertainties are assessed. Finally the fragility curves are combined with the seismic loading to estimate the frequency of failure for each critical scenario. The frequency of failure due to seismic event is presented by the scenario with the highest frequency. The tools usually applied for probabilistic safety analyses of critical structures could relatively easily be adopted to ordinary structures. The key problems are the seismic hazard definitions and the fragility analyses. The fragility could be derived either based on scaling procedures or on the base of generation. Both approaches have been presented in the paper. After the seismic risk (in terms of failure probability) is assessed there are several approaches for risk reduction. Generally the methods could be classified in two groups. The

    Full Text Available Students, who are working on the thesis, have some difficulties caused by internal and external factors. Those problems can disrupt the completion of their thesis, such as the tendency to do academic procrastination. Increasing achievement motivation can reduce academic procrastination. This study aims to look at the role of achievement motivation (hope of success and fear of failure in predicting academic procrastination. The study used a quantitative approach by distributing academic procrastination and achievement motivation questionnaires. The study involved 182 students who were working on a thesis as samples, which were obtained by using accidental sampling technique. Data were analyzed using multiple regressions. It showed that the hope of success and fear of failure have a significant role in predicting academic procrastination (R2 = 13.8%, F = 14,356, p <0.05. The hope of success can decrease academic procrastination, while fear of failure can improve it. Thus, interventions to reduce academic procrastination can be delivered by increasing students hope of success.

    2013-11-01

    Generic skills or transferable skills have been discussed in terms of whether or not skills learned in one context can be transferred into another context. The current study was aimed to explore nurses' self-perceptions of the knowledge and skills they had obtained while writing a Bachelor's thesis in nursing education, their experience of the extent of transfer and utilization in their current work. Responding nurses (N=42) had all worked from 1 to 1.5 years after their final examination and had completed a questionnaire that was structured with open-ended questions. Only five nurses reported that they were unable to use any of the knowledge and skills they had obtained from writing a thesis. A majority of the nurses (37/42) could give many examples of the practical application of the skills and knowledge they had obtained. Our findings indicate that writing a thesis as part of an undergraduate degree program plays a major role in the acquisition and development of knowledge and skills which can subsequently be transferred into and utilized in nursing practice.

    1999-12-01

    A doctoral thesis is described analyzing the relationships between demographic growth and economic and social development in Mali. The hypothesis is stated that demographic growth impedes economic development and any improvement in populations¿ standards of living. The hypothesis was verified using data for the period from 1960 to the present. Over that period, Mali conducted two general population censuses in 1976 and 1987, as well as several demographic research studies. The thesis is comprised of 4 parts, of which the first generally describes Mali. The second part analyzes the relationship between population growth and economic and social development in Mali. Study results are presented, followed by an analysis of the effects of economic and social development upon population growth in Mali through factors such as urbanization, education level, literacy, income, employment, occupation, gross domestic or gross national product by inhabitant, infant mortality rate, life expectancy at birth, contraceptive practice, fertility opinions and desires, women¿s status, and migration in Mali. Analysis indicates that Mali has not completely begun its demographic transition, but that traditional pronatalist behaviors are changing. Population policies and programs are explored in the third part of the thesis, followed by the fourth part which focuses upon methodological questions.

  4. A channel profile analyser

    International Nuclear Information System (INIS)

    Gobbur, S.G.

    1983-01-01

    It is well understood that due to the wide band noise present in a nuclear analog-to-digital converter, events at the boundaries of adjacent channels are shared. It is a difficult and laborious process to exactly find out the shape of the channels at the boundaries. A simple scheme has been developed for the direct display of channel shape of any type of ADC on a cathode ray oscilliscope display. This has been accomplished by sequentially incrementing the reference voltage of a precision pulse generator by a fraction of a channel and storing ADC data in alternative memory locations of a multichannel pulse height analyser. Alternative channels are needed due to the sharing at the boundaries of channels. In the flat region of the profile alternate memory locations are channels with zero counts and channels with the full scale counts. At the boundaries all memory locations will have counts. The shape of this is a direct display of the channel boundaries. (orig.)

  5. Reliability Analyses of Groundwater Pollutant Transport

    Energy Technology Data Exchange (ETDEWEB)

    Dimakis, Panagiotis

    1997-12-31

    This thesis develops a probabilistic finite element model for the analysis of groundwater pollution problems. Two computer codes were developed, (1) one using finite element technique to solve the two-dimensional steady state equations of groundwater flow and pollution transport, and (2) a first order reliability method code that can do a probabilistic analysis of any given analytical or numerical equation. The two codes were connected into one model, PAGAP (Probability Analysis of Groundwater And Pollution). PAGAP can be used to obtain (1) the probability that the concentration at a given point at a given time will exceed a specified value, (2) the probability that the maximum concentration at a given point will exceed a specified value and (3) the probability that the residence time at a given point will exceed a specified period. PAGAP could be used as a tool for assessment purposes and risk analyses, for instance the assessment of the efficiency of a proposed remediation technique or to study the effects of parameter distribution for a given problem (sensitivity study). The model has been applied to study the greatest self sustained, precipitation controlled aquifer in North Europe, which underlies Oslo`s new major airport. 92 refs., 187 figs., 26 tabs.

  6. NOAA's National Snow Analyses

    NOAA's National Operational Hydrologic Remote Sensing Center (NOHRSC) routinely ingests all of the electronically available, real-time, ground-based, snow data; airborne snow water equivalent data; satellite areal extent of snow cover information; and numerical weather prediction (NWP) model forcings for the coterminous U.S. The NWP model forcings are physically downscaled from their native 13 km2 spatial resolution to a 1 km2 resolution for the CONUS. The downscaled NWP forcings drive an energy-and-mass-balance snow accumulation and ablation model at a 1 km2 spatial resolution and at a 1 hour temporal resolution for the country. The ground-based, airborne, and satellite snow observations are assimilated into the snow model's simulated state variables using a Newtonian nudging technique. The principle advantages of the assimilation technique are: (1) approximate balance is maintained in the snow model, (2) physical processes are easily accommodated in the model, and (3) asynoptic data are incorporated at the appropriate times. The snow model is reinitialized with the assimilated snow observations to generate a variety of snow products that combine to form NOAA's NOHRSC National Snow Analyses (NSA). The NOHRSC NSA incorporate all of the available information necessary and available to produce a "best estimate" of real-time snow cover conditions at 1 km2 spatial resolution and 1 hour temporal resolution for the country. The NOHRSC NSA consist of a variety of daily, operational, products that characterize real-time snowpack conditions including: snow water equivalent, snow depth, surface and internal snowpack temperatures, surface and blowing snow sublimation, and snowmelt for the CONUS. The products are generated and distributed in a variety of formats including: interactive maps, time-series, alphanumeric products (e.g., mean areal snow water equivalent on a hydrologic basin-by-basin basis), text and map discussions, map animations, and quantitative gridded products

  7. A numerical study of fundamental shock noise mechanisms. Ph.D. Thesis - Cornell Univ.

    Science.gov (United States)

    Meadows, Kristine R.

    1995-01-01

    The results of this thesis demonstrate that direct numerical simulation can predict sound generation in unsteady aerodynamic flows containing shock waves. Shock waves can be significant sources of sound in high speed jet flows, on helicopter blades, and in supersonic combustion inlets. Direct computation of sound permits the prediction of noise levels in the preliminary design stage and can be used as a tool to focus experimental studies, thereby reducing cost and increasing the probability of a successfully quiet product in less time. This thesis reveals and investigates two mechanisms fundamental to sound generation by shocked flows: shock motion and shock deformation. Shock motion is modeled by the interaction of a sound wave with a shock. During the interaction, the shock wave begins to move and the sound pressure is amplified as the wave passes through the shock. The numerical approach presented in this thesis is validated by the comparison of results obtained in a quasi-one dimensional simulation with linear theory. Analysis of the perturbation energy demonstrated for the first time that acoustic energy is generated by the interaction. Shock deformation is investigated by the numerical simulation of a ring vortex interacting with a shock. This interaction models the passage of turbulent structures through the shock wave. The simulation demonstrates that both acoustic waves and contact surfaces are generated downstream during the interaction. Analysis demonstrates that the acoustic wave spreads cylindrically, that the sound intensity is highly directional, and that the sound pressure level increases significantly with increasing shock strength. The effect of shock strength on sound pressure level is consistent with experimental observations of shock noise, indicating that the interaction of a ring vortex with a shock wave correctly models a dominant mechanism of shock noise generation.

    Interestingly, there are very few guidelines in the literature to assist novice nurse PhD examiners. In this paper, we aim to provide information to nurses, researchers or early career academics who have little experience in assessing a university thesis. The article provides background information about recent changes in the university sector; overviews some research on experienced examiners views; presents factors that differentiate between high and low quality PhD theses; and outlines some pointers that may be useful when marking at the doctoral level.

    Directory of Open Access Journals (Sweden)

    Aida Sotelo Céspedes

    2016-08-01

    Full Text Available This essay questions the place given to the human body in our time because of the consequences of the western thesis of human exception and its presence in Descartes' cogito that led to modern science, and also because of the effects of fragmentation, politicization and merchandising of life in the second modernity, derived from the capitalist discourse. As a counterpoint not necessarily grounded on those beliefs and deviations of scientific and social morality, forty years ago people began to talk about bioethics. Today, it is necessary to update its teaching, and that means its secularization and independence of law, which more often than not has been against ethics.

  11. Vibro-spring particle size distribution analyser

    International Nuclear Information System (INIS)

    Patel, Ketan Shantilal

    2002-01-01

    This thesis describes the design and development of an automated pre-production particle size distribution analyser for particles in the 20 - 2000 μm size range. This work is follow up to the vibro-spring particle sizer reported by Shaeri. In its most basic form, the instrument comprises a horizontally held closed coil helical spring that is partly filled with the test powder and sinusoidally vibrated in the transverse direction. Particle size distribution data are obtained by stretching the spring to known lengths and measuring the mass of the powder discharged from the spring's coils. The size of the particles on the other hand is determined from the spring 'intercoil' distance. The instrument developed by Shaeri had limited use due to its inability to measure sample mass directly. For the device reported here, modifications are made to the original configurations to establish means of direct sample mass measurement. The feasibility of techniques for measuring the mass of powder retained within the spring are investigated in detail. Initially, the measurement of mass is executed in-situ from the vibration characteristics based on the spring's first harmonic resonant frequency. This method is often erratic and unreliable due to the particle-particle-spring wall interactions and the spring bending. An much more successful alternative is found from a more complicated arrangement in which the spring forms part of a stiff cantilever system pivoted along its main axis. Here, the sample mass is determined in the 'static mode' by monitoring the cantilever beam's deflection following the wanton termination of vibration. The system performance has been optimised through the variations of the mechanical design of the key components and the operating procedure as well as taking into account the effect of changes in the ambient temperature on the system's response. The thesis also describes the design and development of the ancillary mechanisms. These include the pneumatic

    Carol Davila, the father of the Romanian modern medicine, made decisive contributions to the development of health sciences in the Romanian Principalities in the last decades of the nineteenth century. The merit of his scientific work was recognized beyond the borders of his country. His life (not devoid of anecdotic instances and unknown episodes) and especially his work have aroused considerable interest among numerous medical historians. This paper presents a historical study elaborated in France, but until recently ignored, dedicated to the biography of Carol Davila. It concerns the medical doctoral thesis (State Diploma) elaborated by Joseph Adler (born 1910 in Botoşani, Romania) under the supervision of professor Maxime Laignel-Lavastine, whose interest in Romania is well-known. Professor Laignel-Lavastine held the office of Secretary General of the International Society of History of Medicine (ISHM), founded in 1921, (replaced in this position by another French professor with links to Romania: Jules Guiart). The thesis comprises 48 pages and an exhaustive bibliography. It represents a token of the appreciation given to Davila's achievements by Europe's medical community.

    Medeiros, Marcelo; Diniz, Debora; Schwartz, Ida Vanessa Doederlein

    2013-04-01

    This paper evaluates the hypothesis that the judicialization of medicine for mucopolysaccharidosis in Brazil is an action promoted by economic elites. Previous studies upholding the thesis of judicialization by elites in the case of other types of medication that are more costly for the Unified Health Service are discussed. An analysis of all 196 processes containing information about judicial processes brought to court between February 2006 and December 2010 that ended by determining that the State should provide such medication free of charge to patients was conducted. There is evidence that attorneys' fees were covered by entities interested in the results of judicialization, such as the distributors or pharmaceutical industries. Patients may also be migrating for diagnosis and treatment to university centers that are a benchmark for medical innovation in the country, as the option for public health services is related to their higher technical and scientific capacity. Therefore, the resort to private lawyers, indicators of social exclusion based on the address of patients and the use of public health services, are not adequate class information to corroborate or refute the thesis of judicialization by the elites.

  15. Want to Improve Undergraduate Thesis Writing? Engage Students and Their Faculty Readers in Scientific Peer Review

    One of the best opportunities that undergraduates have to learn to write like a scientist is to write a thesis after participating in faculty-mentored undergraduate research. But developing writing skills doesn't happen automatically, and there are significant challenges associated with offering writing courses and with individualized mentoring. We present a hybrid model in which students have the structural support of a course plus the personalized benefits of working one-on-one with faculty. To optimize these one-on-one interactions, the course uses BioTAP, the Biology Thesis Assessment Protocol, to structure engagement in scientific peer review. By assessing theses written by students who took this course and comparable students who did not, we found that our approach not only improved student writing but also helped faculty members across the department—not only those teaching the course—to work more effectively and efficiently with student writers. Students who enrolled in this course were more likely to earn highest honors than students who only worked one-on-one with faculty. Further, students in the course scored significantly better on all higher-order writing and critical-thinking skills assessed. PMID:21633069

  17. Reality Television, The Hills and the Limits of the Immaterial Labour Thesis

    Directory of Open Access Journals (Sweden)

    Alison Mary Virginia Hearn

    2010-05-01

    Full Text Available This paper will examine the immaterial labour thesis as proposed by Michael Hardt and Antonio Negri through a case study of reality television production practices, specifically those of the MTV program, The Hills. Because immaterial labour is rooted in individual intelligence, affect, and social communicative capacities, Hardt and Negri contend that economic value in the form of labour power can no longer be adequately measured and quantified and that this immeasurability contains revolutionary potential. But, given the current global economic meltdown, and the persistent and very material suffering of people all over the globe, how legitimate and responsible are these claims? Drawing from interviews with reality television workers and the work of George Caffentzis, Massimo de Angelis, David Harvie and others, this paper will test the limits of the immaterial labour thesis, arguing that, rather than disappearing, capital continues to impose measurement systems to determine socially necessary labour time no matter how diffuse or social that labour might be, and that this imposition continues to produce the alienation and exploitation of many for the benefit of a few.

    Murdock, J.M.

    1994-12-01

    The purpose of this thesis was to investigate the factors affecting the allowability determination of defense contractor environmental remediation costs. The primary objective of this thesis was to determine what policies and contracting cost principles the Department of Defense (DOD) should develop to address environmental costs in a consistent manner, providing a `single face` to industry. A secondary objective was to develop an audit framework and questions to allow for consistent policy analysis and application to a contractor`s proposed environmental remediation costs based upon the materiality of the situation. Background material was presented to show the amount and complexity of environmental regulations, the effects of current judicial decisions and DOD`s efforts to develop a consistent policy. Research material was provided from Congress, the General Accounting Office, DOD, defense contractors, California, Washington, industry associations and environmental protection coalitions. The researcher`s analysis of the material produced an environmental cost principle. This cost principle was applied to a current environmental claim, producing an audit framework and tailored list of cost and/or pricing data analysis, questions. Both the cost principle and audit framework are recommended for incorporation into DOD`s final environmental cost allowability decision.

    Full Text Available Recently I completed a performative (creative PhD in the School of Creative Communication (now the Faculty of Design and Creative Practice at the University of Canberra, Australia, where such doctorates were established only in 2002. Since I completed in 2006, I have been contemplating some process issues that emerged during my three and a half year's studies. While conferring with fellow students and colleagues at three universities in England, I found that the many of the problems they encountered were similar and so were not due uniquely to the innovative phase that I encountered, but were part of a wider scenario. At my university, the requirements for a creative doctorate are a creative component (equivalent to about 60,000 words and a theoretical component (exegesis of about 30,000 words. The physical outcome of my thesis is two artist's books: one, Tissue, is autobiographical, while questioning the nature of autobiography, memory and identity. The other, Re-Picturing My Life, is the theoretical component, examining several paradigms including issues of methodology; the value of art as research; theories of memory, identity, autobiography, and human interactions with objects. I have placed some of my text/images in this paper to provide a taste of the work in my thesis. My paper reflects on performative work in the context of academic research, and the resilience, determination and sense of humour needed to complete a doctorate successfully in this valuable area of endeavour.

  20. Radiation and scattering from cylindrically conformal printed antennas. Ph.D. Thesis Final Report

    Science.gov (United States)

    Kempel, Leo C.; Volakis, John L.

    1994-01-01

    Microstrip patch antennas offer considerable advantages in terms of weight, aerodynamic drag, cost, flexibility, and observables over more conventional protruding antennas. These flat patch antennas were first proposed over thirty years ago by Deschamps in the United States and Gutton and Baisinot in France. Such antennas have been analyzed and developed for planar as well as curved platforms. However, the methods used in these designs employ gross approximations, suffer from extreme computational burden, or require expensive physical experiments. The goal of this thesis is to develop accurate and efficient numerical modeling techniques which represent actual antenna structures mounted on curved surfaces with a high degree of fidelity. In this thesis, the finite element method is extended to cavity-backed conformal antenna arrays embedded in a circular, metallic, infinite cylinder. Both the boundary integral and absorbing boundary mesh closure conditions will be used for terminating the mesh. These two approaches will be contrasted and used to study the scattering and radiation behavior of several useful antenna configurations. An important feature of this study will be to examine the effect of curvature and cavity size on the scattering and radiation properties of wraparound conformal antenna arrays.

  1. THE WEBER THESIS OF CALVINISM AND CAPITALISM--ITS VARIOUS VERSIONS AND THEIR "FATE" IN SOCIAL SCIENCE.

    Zafirovski, Milan

    2016-01-01

    The paper identifies and examines various multiple renditions of the so-called Weber Thesis of an historical association and convergence between ascetic Protestantism, above all Calvinism, and the emergence and development of modern capitalism as an economic spirit and system. Specifically, it detects at least four different versions and formulations or interpretations, thus casting doubt in the common view of the Weber Thesis as a single and monolithic theory or hypothesis. The paper also considers the status of the multiple versions of the Weber Thesis in post-Weberian and contemporary sociology and related disciplines like economics and history. It concludes that the weaker, relaxed renditions of the Weber Thesis have attained a greater success and more endured in contemporary social science than have its stronger, stricter versions. © 2015 Wiley Periodicals, Inc.

    The Asian population in Britain has grown, representing the second largest ethnic group; Bangladeshi, Pakistani, and Indian nationalities are prevalent (Jivraj, 2012 ; Office for National Statistics, 2013 ). Yet, we know relatively little about the nature and extent of their substance use. Jayakody et al. ( 2006 ) argue ethnic minority groups may be influenced by the norms and values of the dominant culture. Given recreational drug use has undergone a process of normalization in Britain (Aldridge et al., 2011 ; Parker et al., 1998 , 2002 ), we explore the degree to which this is occurring in a Bangladeshi and Pakistani community of Muslim faith in Northern England; a group typically assumed to reject substance use because of robust religious and cultural values. To examine the extent, frequency, and nature of substance use, and associated attitudes. A cross-sectional study collecting qualitative data from a sample (N = 43) of adolescents accessing a drug service and a range of professionals working with them during 2014. We also present analyses of routinely collected quantitative client data. Adolescent interviewees reported extensive personal experience smoking skunk cannabis, and professionals working in the community confirmed many young Asians smoked it. Its consumption appeared to be accommodated into the daily lives of young people and the supply of it also showed signs of acceptance. Skunk cannabis may be undergoing a process of normalization within some Asian communities in Britain. Our study has significant implications for the normalization thesis, finding evidence for normalization within a subpopulation that is typically perceived to resist this trend.

    2009-01-01

    The prominent philosopher, theologian, physician, musicologist and organ soloist Albert Schweitzer (14. 1. 1875-4. 9. 1965) submitted his MD thesis Kritik der von medizinischer Seite veröffentlichten Pathographien uber Jesus (Criticism of the medical pathographies on Jesus) in 1913. Very soon he published this work under the title Die psychiatrische Beurteilung Jesu. Darstellung und Kritik (The psychiatric evaluation of Jesus. Description and criticism) in order to reach a broader audience. Schweitzer's explicit motive for selecting this topic was to influence the theological debate by means of a M. D. thesis on psychiatric pathographies on Jesus. He was confronted with a lot of reproaches. These reproaches contended that his theological opinions had been supporting tendencies to describe Jesus as a mentally ill person or a religious fanatic. In addition, some authors of pathographies on Jesus (De Loosten, Binet-Sanglé, Hirsch, Rasmussen) characterized Jesus as mentally ill, suffering from paranoia. Schweitzer intended to reject the reproaches considering himself and the postulates of the authors of the pathographies. Schweitzer combined in a transdisciplinary way theological, psychiatric and psychopathological arguments. He did this in a very convincing way. Although Schweitzer did not deal with a central or explicit psychiatric question, he implicitly postulated transdisciplinary approaches for proper retrospective pathographies on historic persons. At the age of thirty, Schweitzer decided to finish his academic career and to begin studies in medicine as a preparation for work as a physician in Africa. This decision provoked much lack of understanding in his personal environment. Therefore it may be possible that a very personal motive contributed to the selection of the topic of the MD thesis. Among psychiatric authorities, Albert Schweitzer's interest in the criticisms of psychiatric pathographies and his transdisciplinary approach to this topic encountered

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

    It is clear that lithium fluoride thermoluminescent (Tl) material is the most superior among all other commercially available Tl-materials. This fact leads to various application in radiation dosimetry because of its tissue equivalent response to radiation . However, this advantage is greatly defected by high cost of LiF, its complicated behaviour under heat treatment and radiation damage effect. therefore, great efforts are still made in many laboratories in order to obtain a lost cost tissue equivalent Tl-dosimeter. In the frame of the present thesis, the Tl - properties of some naturally occurring materials were studied for the sake of possible substitution of LiF. A brief but condense theoretical analysis of the Tl - mechanism in solids were treated and discussed to enable direct intercomparison with experimental data. The primary investigations lead to the selection of three promising natural occurring materials; namely; quartz, Feldspar and barite

    According to a good definition, evidence-based medicine (EBM) is: "The explicit, conscientious, and judicious use of the current best evidence in making decisions about the care of individual patients (and populations)". More appropriate in a clinical context like that of physical and rehabilitation medicine (PRM) is looking at evidence based clinical practice (EBCP), whose definition is: "The integration of best research evidence with clinical expertise and patient values". In the past the term evidence-based physical and rehabilitation medicine (EBPRM) was also proposed. In this thesis, after some historical notes on EBM and on PRM, we will discuss why in our view EBPRM must be the real foundation of our everyday PRM clinical practice.

    2015-12-01

    According to the Russo-Williamson Thesis, causal claims in the health sciences need to be supported by both difference-making and mechanistic evidence. In this article, we attempt to determine whether Evidence-based Medicine (EBM) can be improved through the consideration of mechanistic evidence. We discuss the practical composition and function of each RWT evidence type and propose that exposure-outcome evidence (previously known as difference-making evidence) provides associations that can be explained through a hypothesis of causation, while mechanistic evidence provides finer-grained associations and knowledge of entities that ultimately explains a causal hypothesis. We suggest that mechanistic evidence holds untapped potential to add value to the assessment of evidence quality in EBM and propose initial recommendations for the integration of mechanistic and exposure-outcome evidence to improve EBM by robustly leveraging available evidence in support of good medical decisions.

In the third chapter there are presented the experimental data obtained from different samples prepared in different temperature and magnetic field conditions. The obtained results are finally interpreted in the frame of existent or original models. (M.I.C.). 31 Refs

  12. Magnesium and its transport in tilapia and carp: A study based on nuclear methods. Thesis

    Energy Technology Data Exchange (ETDEWEB)

    van der Velden, J.A.

    1993-01-01

    The experiments described in this thesis deal with the production of radiotracers for magnesium and the magnesium metabolism of freshwater tilapia and carp. In chapter 2 the technique of instrumental neutron activation analysis, and the production and properties of two radioisotopes of magnesium are described. In chapter 3 the magnesium distribution and the magnesium inventory of carp and tilapia is described, mainly by the use of instrumental neutron activation analysis. Chapter 4 deals with magnesium transport (in vivo and in vitro) between the water and fish and food and fish. In chapter 5 effects of a low-magnesium diet on tissue mineral concentrations, on the ion regulation and on magnesium transport of fish is described. Chapter 6 deals with the effects of low ambient magnesium on early life stages of the fish.

  13. A thesis on the Development of an Automated SWIFT Edge Detection Algorithm

    2016-07-28

    Throughout the world, scientists and engineers such as those at Los Alamos National Laboratory, perform research and testing unique only to applications aimed towards advancing technology, and understanding the nature of materials. With this testing, comes a need for advanced methods of data acquisition and most importantly, a means of analyzing and extracting the necessary information from such acquired data. In this thesis, I aim to produce an automated method implementing advanced image processing techniques and tools to analyze SWIFT image datasets for Detonator Technology at Los Alamos National Laboratory. Such an effective method for edge detection and point extraction can prove to be advantageous in analyzing such unique datasets and provide for consistency in producing results.

  14. Deep venous thrombosis: The valve cusp hypoxia thesis and its incompatibility with modern orthodoxy.

    Science.gov (United States)

    Malone, P Colm; Agutter, Paul S

    2016-01-01

    The valve cusp hypoxia thesis (VCHT) of the aetiology of deep venous thrombosis (DVT) was adumbrated in this journal in 1977 and fully articulated in 2008, the original hypothesis having been strongly corroborated by experiments published in 1981 and 1984. It presents a unitary account of the pathogenesis of venous thrombosis and embolism that is rooted in the pathophysiological tradition of Hunter, Virchow, Lister, Welch and Aschoff, a tradition traceable back to Harvey. In this paper we summarise the thesis in its mature form, consider its compatibility with recent advances in the DVT field, and ask why it has not yet been assimilated into the mainstream literature, which during the past half century has been dominated by a haematology-orientated 'consensus model'. We identify and discuss seven ways in which the VCHT is incompatible with these mainstream beliefs about the aetiology of venous thrombosis, drawing attention to: (1) the spurious nature of 'Virchow's triad'; (2) the crucial differences between 'venous thrombus' and 'clot'; the facts that (3) venous thrombi form in the valve pockets (VVPs), (4) DVT is not a primarily haematological condition, (5) the so-called 'thrombophilias' are not thrombogenic per se; (6) the conflict between the single unitary aetiology of DVT and the tacit assumption that the condition is 'multicausal'; (7) the inability of anticoagulants to prevent the initiation of venous thrombogenesis, though they do prevent the growth of thrombi to clinically significant size. In discussing point (7), we show that the VCHT indicates new approaches to mechanical prophylaxis against DVT. These approaches are then formulated as experimentally testable hypotheses, and we suggest methods for testing them preclinically using animal trials. Copyright © 2015 Elsevier Ltd.

  15. Effects of medical school selection on student motivation: a PhD thesis report.

    Science.gov (United States)

    2018-02-01

    High stakes are involved in student selection, for both medical schools and applicants. This thesis investigated the effects of selection on the medical student population and applicant pool in the Dutch setting. This thesis consists of six papers: two quantitative studies, one qualitative study, two mixed methods studies and one perspective paper based on a review of the literature. (1) Compared with a lottery, selection does not result in a student population with better motivation, engagement and performance, both in the clinical and pre-clinical phases of the study. (2) Selection seems to have a temporary stimulating effect on student motivation through enhancing perceived autonomy, competence and relatedness. (3) Applicants adopt a strategic approach, based on the selection procedure, in their choice of medical school. (4) The description of an applicant's motivation is not a reliable and valid tool to assess motivation during selection. (5) Gaining healthcare experience is crucial for applicants' motivation, but inequalities in access to such experiences can demotivate certain student groups from applying to medical school. (6) The gains yielded from selection compared with a lottery seem to be small. Unintentionally induced self-selection among certain groups of students and biased selection procedures may compromise student diversity. The added value of selection procedures compared with a weighted lottery for admitting students to medical school is questionable. Students are generally motivated and perform well, irrespective of how they enrolled in medical school. Selection yields only small gains, while student diversity may be hampered.

  16. SUPERVISING IN ENGLISH: THE DOCTORAL THESIS, PROFES­SOR/ STUDENT DISCOURSE, AND SOCIAL PRACTICE

    Directory of Open Access Journals (Sweden)

    Jane Mattisson

    2014-04-01

    Full Text Available y article investigates the situation, goals, and discourse praxis of professors supervising doctoral students writing in English. It is part of a wider project examining student-teacher interaction which is designed to improve written communication, particularly at the higher levels of academic study. Like the students they supervise, the five professors studied are English as a Foreign Language users, and all give instruction exclusively in English. Based on separate interviews with each professor, my study demonstrates that there is a tendency among doctoral supervisors to focus on the content and form of the thesis to the detriment of socio-cultural practice, i.e., the discourse between the professor and student, as well as the recognition of the text as a piece of social practice, shaped by a particular kind of academic public and the rules of scholarship that have been developed over time. The type of social practice that students bring with them varies from culture to culture. I argue that a doctoral thesis bears witness not only to the student’s ability to conduct research at a high level, but also to the creation of a distinct scholarly identity that is the result of effective discourse between professor and student, whereby the professor communicates “the rules of the game” that lead to a successful career both at university and after. My paper reflects on how we as teachers/supervisors can promote the formation of scholarly identity through the medium of English as a Foreign Language. I do so by focusing on the five supervisors’ knowledge of English, their ability to provide guidance in English, and their awareness of the importance of promoting scholarly identity in English. The article concludes with some reflections on the type of support required, if any, from native English teachers.

  17. Understanding the Complex Relationship between Critical Thinking and Science Reasoning among Undergraduate Thesis Writers.

    2018-01-01

    Developing critical-thinking and scientific reasoning skills are core learning objectives of science education, but little empirical evidence exists regarding the interrelationships between these constructs. Writing effectively fosters students' development of these constructs, and it offers a unique window into studying how they relate. In this study of undergraduate thesis writing in biology at two universities, we examine how scientific reasoning exhibited in writing (assessed using the Biology Thesis Assessment Protocol) relates to general and specific critical-thinking skills (assessed using the California Critical Thinking Skills Test), and we consider implications for instruction. We find that scientific reasoning in writing is strongly related to inference , while other aspects of science reasoning that emerge in writing (epistemological considerations, writing conventions, etc.) are not significantly related to critical-thinking skills. Science reasoning in writing is not merely a proxy for critical thinking. In linking features of students' writing to their critical-thinking skills, this study 1) provides a bridge to prior work suggesting that engagement in science writing enhances critical thinking and 2) serves as a foundational step for subsequently determining whether instruction focused explicitly on developing critical-thinking skills (particularly inference ) can actually improve students' scientific reasoning in their writing. © 2018 J.

    Uysal Toraman, Aynur; Hamaratçılar, Güler; Tülü, Begüm; Erkin, Özüm

    2017-04-01

    The aim of this study was to investigate the effect of writing a bachelor's thesis on nursing students' attitudes towards research and development in nursing. The study sample consisted of 91 nursing students who were required to complete a bachelor's thesis and 89 nursing students who were not required to complete a bachelor's thesis. Data were collected via self-report questionnaire that was distributed in May and June 2012. The questionnaire comprised 3 parts: (1) demographic items; (2) questions about "scientific activities," and (3) the nursing students' attitudes towards and awareness of research and development within nursing scale (version 2). The mean age of the students was 23 (1.3) years. The students who wrote a bachelor's thesis achieved a median score of 110.0, whereas the students in the other group had a median score of 105.0 on the scale. All the items were assigned a 3 or higher. A statistically significant difference was found between the 2 groups in their attitudes towards and awareness of research (U = 3265.5; P = .025). The results of this study suggest that writing a thesis in nursing education has a positive influence on nursing students' attitudes towards and awareness of research and development in nursing. © 2017 John Wiley & Sons Australia, Ltd.

  1. Bridging the Gaps Between Students’ Prior Knowledge and Skills in Writing and the Expected Thesis Outcomes

    Full Text Available This research aimed to seek the light on how the advisors made a use of feedback during supervisory panel and find out how different ways and types of feedback impacted on student-writers’ thesis outcomes. Qualitative study was applied by involving three tenured lecturers at College of Islamic Studies, in Java as the research subjects. Two data collection techniques were applied, such as interview and documentation, to trace evidence on what types of feedback used, how students noticed, and how they impacted on subsequent drafts. This study revealed that indirect feedback using error codes and commentary was the most frequent form used during the advisory session. However, the mere use of feedback could only serve a short-term impact on the development of writing, and even it seemed only to spoon-feed them which could create burdens in writing. It was quite evident that engaging them in such self-regulated and interdependence group works, through problem-solving discussion and peer review, was much worthier as compared to only ask them to process the feedback themselves.

    Chatterjee, A.; Volakis, John L.; Nguyen, J.

    1994-01-01

    The mechanics of wave propagation in the presence of obstacles is of great interest in many branches of engineering and applied mathematics like electromagnetics, fluid dynamics, geophysics, seismology, etc. Such problems can be broadly classified into two categories: the bounded domain or the closed problem and the unbounded domain or the open problem. Analytical techniques have been derived for the simpler problems; however, the need to model complicated geometrical features, complex material coatings and fillings, and to adapt the model to changing design parameters have inevitably tilted the balance in favor of numerical techniques. The modeling of closed problems presents difficulties primarily in proper meshing of the interior region. However, problems in unbounded domains pose a unique challenge to computation, since the exterior region is inappropriate for direct implementation of numerical techniques. A large number of solutions have been proposed but only a few have stood the test of time and experiment. The goal of this thesis is to develop an efficient and reliable partial differential equation technique to model large three dimensional scattering problems in electromagnetics.

  3. Entrepreneurial proliferation: Russia`s nuclear industry suits the buyers market. Master`s thesis

    Energy Technology Data Exchange (ETDEWEB)

    Whalen, T.D.; Williams, A.R.

    1995-06-01

    The Soviet Union collapsed in December 1991, bringing an end to four decades of the Cold War. A system of tight centralized controls has given way to chaotic freedom and un-managed, entrepreneurial capitalism. Of immediate concern to most world leaders has been the control and safety of over 30,000 Soviet nuclear weapons. After 1991, the Soviet, centralized system of management lost one key structural element: a reliable `human factor` for nuclear material control. The Soviet systems for physical security and material control are still in place in the nuclear inheritor states - Russia, Ukraine, Khazakhnstan, and Belarus - but they do not restrain or regulate their nuclear industry. In the chaos created by the Soviet collapse, the nonproliferation regime may not adequately temper the supply of the nuclear materials of the new inheritor states. This could permit organizations or states seeking nuclear weapons easier access to fissile materials. New initiatives such as the United States Cooperative Threat Reduction program, which draws upon U.S. technology and expertise to help the NIS solve these complex problems, are short-tern tactics. At present there are no strategies which address the long-tern root problems caused by the Soviet collapse.This thesis demonstrates the extent of the nuclear control problems in Russia. Specifically, we examine physical security, material control and accounting regulation and enforcement, and criminal actions. It reveals that the current lack of internal controls make access to nuclear materials easier for aspiring nuclear weapons States.

  4. The Radical Plasticity Thesis: How the Brain Learns to be Conscious.

    Science.gov (United States)

    Cleeremans, Axel

    2011-01-01

    In this paper, I explore the idea that consciousness is something that the brain learns to do rather than an intrinsic property of certain neural states and not others. Starting from the idea that neural activity is inherently unconscious, the question thus becomes: How does the brain learn to be conscious? I suggest that consciousness arises as a result of the brain's continuous attempts at predicting not only the consequences of its actions on the world and on other agents, but also the consequences of activity in one cerebral region on activity in other regions. By this account, the brain continuously and unconsciously learns to redescribe its own activity to itself, so developing systems of meta-representations that characterize and qualify the target first-order representations. Such learned redescriptions, enriched by the emotional value associated with them, form the basis of conscious experience. Learning and plasticity are thus central to consciousness, to the extent that experiences only occur in experiencers that have learned to know they possess certain first-order states and that have learned to care more about certain states than about others. This is what I call the "Radical Plasticity Thesis." In a sense thus, this is the enactive perspective, but turned both inwards and (further) outwards. Consciousness involves "signal detection on the mind"; the conscious mind is the brain's (non-conceptual, implicit) theory about itself. I illustrate these ideas through neural network models that simulate the relationships between performance and awareness in different tasks.

  5. Failure analysis and modeling of a multicomputer system. M.S. Thesis

    Subramani, Sujatha Srinivasan

    1990-01-01

    This thesis describes the results of an extensive measurement-based analysis of real error data collected from a 7-machine DEC VaxCluster multicomputer system. In addition to evaluating basic system error and failure characteristics, we develop reward models to analyze the impact of failures and errors on the system. The results show that, although 98 percent of errors in the shared resources recover, they result in 48 percent of all system failures. The analysis of rewards shows that the expected reward rate for the VaxCluster decreases to 0.5 in 100 days for a 3 out of 7 model, which is well over a 100 times that for a 7-out-of-7 model. A comparison of the reward rates for a range of k-out-of-n models indicates that the maximum increase in reward rate (0.25) occurs in going from the 6-out-of-7 model to the 5-out-of-7 model. The analysis also shows that software errors have the lowest reward (0.2 vs. 0.91 for network errors). The large loss in reward rate for software errors is due to the fact that a large proportion (94 percent) of software errors lead to failure. In comparison, the high reward rate for network errors is due to fast recovery from a majority of these errors (median recovery duration is 0 seconds).

  6. The animal sensorimotor organization: a challenge for the environmental complexity thesis.

    Science.gov (United States)

    Keijzer, Fred; Arnellos, Argyris

    2017-01-01

    Godfrey-Smith's environmental complexity thesis (ECT) is most often applied to multicellular animals and the complexity of their macroscopic environments to explain how cognition evolved. We think that the ECT may be less suited to explain the origins of the animal bodily organization, including this organization's potentiality for dealing with complex macroscopic environments. We argue that acquiring the fundamental sensorimotor features of the animal body may be better explained as a consequence of dealing with internal bodily-rather than environmental complexity. To press and elucidate this option, we develop the notion of an animal sensorimotor organization (ASMO) that derives from an internal coordination account for the evolution of early nervous systems. The ASMO notion is a reply to the question how a collection of single cells can become integrated such that the resulting multicellular organization becomes sensitive to and can manipulate macroscopic features of both the animal body and its environment. In this account, epithelial contractile tissues play the central role in the organization behind complex animal bodies. In this paper, we relate the ASMO concept to recent work on epithelia, which provides empirical evidence that supports central assumptions behind the ASMO notion. Second, we discuss to what extent the notion applies to basic animal architectures, exemplified by sponges and jellyfish. We conclude that the features exhibited by the ASMO are plausibly explained by internal constraints acting on and within this multicellular organization, providing a challenge for the role the ECT plays in this context.

    2016-01-01

    Today, postgraduate students experience a variety of stresses and anxiety in different situations of academic cycle. Stress and anxiety have been defined as a syndrome shown by emotional exhaustion and reduced personal goal achievement. This article addresses the causes and different strategies of coping with this phenomena by PhD students at Iranian Universities of Medical Sciences. The study was conducted by a qualitative method using conventional content analysis approach. Through purposive sampling, 16 postgraduate medical sciences PhD students were selected on the basis of theoretical sampling. Data were gathered through semistructured interviews and field observations. Six hundred fifty-four initial codes were summarized and classified into 4 main categories and 11 subcategories on the thematic coding stage dependent on conceptual similarities and differences. The obtained codes were categorized under 4 themes including "thesis as a major source of stress," "supervisor relationship," "socioeconomic problem," and "coping with stress and anxiety." It was concluded that PhD students experience stress and anxiety from a variety of sources and apply different methods of coping in effective and ineffective ways. Purposeful supervision and guidance can reduce the cause of stress and anxiety; in addition, coping strategy must be in a thoughtful approach, as recommended in this study.

  8. On Engster's care-justification of the specialness thesis about healthcare.

    Rumbold, Benedict

    2017-08-01

    To say health is 'special' is to say that it has a moral significance that differentiates it from other goods (cars, say or radios) and, as a matter of justice, warrants distributing it separately. In this essay, I critique a new justification for the specialness thesis about healthcare (STHC) recently put forth by Engster. I argue that, regrettably, Engster's justification of STHC ultimately fails and fails on much the same grounds as have previous justifications of STHC. However, I also argue that Engster's argument still adds something valuable to the debate around STHC insofar as it reminds us that the moral significance of healthcare may be wider than simply its effect on the incidence of disability and disease: one further reason we may think healthcare is morally significant is because it concerns the treatment and care of those who are already unwell.

  9. Space-Bounded Church-Turing Thesis and Computational Tractability of Closed Systems.

    Braverman, Mark; Schneider, Jonathan; Rojas, Cristóbal

    2015-08-28

    We report a new limitation on the ability of physical systems to perform computation-one that is based on generalizing the notion of memory, or storage space, available to the system to perform the computation. Roughly, we define memory as the maximal amount of information that the evolving system can carry from one instant to the next. We show that memory is a limiting factor in computation even in lieu of any time limitations on the evolving system-such as when considering its equilibrium regime. We call this limitation the space-bounded Church-Turing thesis (SBCT). The SBCT is supported by a simulation assertion (SA), which states that predicting the long-term behavior of bounded-memory systems is computationally tractable. In particular, one corollary of SA is an explicit bound on the computational hardness of the long-term behavior of a discrete-time finite-dimensional dynamical system that is affected by noise. We prove such a bound explicitly.

  10. Coded throughput performance simulations for the time-varying satellite channel. M.S. Thesis

    Science.gov (United States)

    Han, LI

    1995-01-01

    The design of a reliable satellite communication link involving the data transfer from a small, low-orbit satellite to a ground station, but through a geostationary satellite, was examined. In such a scenario, the received signal power to noise density ratio increases as the transmitting low-orbit satellite comes into view, and then decreases as it then departs, resulting in a short-duration, time-varying communication link. The optimal values of the small satellite antenna beamwidth, signaling rate, modulation scheme and the theoretical link throughput (in bits per day) have been determined. The goal of this thesis is to choose a practical coding scheme which maximizes the daily link throughput while satisfying a prescribed probability of error requirement. We examine the throughput of both fixed rate and variable rate concatenated forward error correction (FEC) coding schemes for the additive white Gaussian noise (AWGN) channel, and then examine the effect of radio frequency interference (RFI) on the best coding scheme among them. Interleaving is used to mitigate degradation due to RFI. It was found that the variable rate concatenated coding scheme could achieve 74 percent of the theoretical throughput, equivalent to 1.11 Gbits/day based on the cutoff rate R(sub 0). For comparison, 87 percent is achievable for AWGN-only case.

    The objective of this study was to describe the development of a primary care medical student's thesis. In 1995, as part of its primary care clerkship, the Charles R. Drew University of Medicine and Science (Drew University), College of Medicine created a curriculum requiring medical students to develop, design, and implement a research project during their 2-year longitudinal clinical experience. For this study, we reviewed all student research projects generated between 1995 and 2004. Among the 112 research projects, topics covered included internal medicine (29.5%), obstetrics and gynecology (OBGYN; 22%), psychosocial issues (20.5%), pediatrics (9%), public health/epidemiology (8%), medical education (8%), and surgery (3%). Mentors included faculty from internal medicine (16%), dean's office (16%), pediatrics (13%), family medicine (11%), non-Drew faculty (10%), OBGYN (9%), psychiatry (9%), surgery (9%), emergency medicine (4%), and pathology/radiology departments (3%). The students' survey showed that 83% agreed that the mentors were valuable, 72% admitted that their knowledge about the research process was improved, about 50% indicated that they were more competitive during residency application, and 80% claimed that they obtained satisfaction from accomplishing a goal. Students are able to conduct and present a primary care research project as a requirement of their medical training. Most students find the experience beneficial and positive.

  13. Reminiscing about thesis work with E T Jaynes at Stanford in the 1950s

    Cummings, Frederick W.

    2013-11-01

    Abstract A short personal and historical account of the field of radiation interacting with (two-level) atoms is given. Subsequent to 1963, developments and extensions have been extensive and fruitful. One of the most fortunate changes in my life came in late 1957. I was looking for a thesis advisor, after two years of graduate course-work at Stanford. I chanced to see a notice of an upcoming lecture by a professor named Edwin T Jaynes. I could not understand from the announcement what he intended to talk about, but I was searching; I went to find out. That decision was a very lucky one. Ed was talking about a subject that inspired him then, and had been for many years, namely his concept of 'Max-Ent'. 'Maximum-Entropy' is a subject now close to my heart also. Ed's very-clear, well-thought-out papers, spread over many subsequent years, are transforming the field of probability (albeit too gradually) to the 'subjective' outlook of Bayes. (A recent book 'Maximum Entropy and Ecology' [1] will probably convert many nay-sayers to 'Max-Ent'.) I went into Ed's office (late 1957) and asked if I could work with him on a thesis. Did he have a problem for me? Yes, he did. Somewhat to my surprise, he asked me to look into the 'maser problem', involving a comparison of the semi-classical theory of radiation to a proper quantum treatment. To make a two-year story short, Ed's guidance was expert. (I imagine that if another of Ed's students (e.g. Joe Eberly) had come into his office fifteen minutes before me, the 'Jaynes-Cummings' (J-C) model would now perhaps be called otherwise, e.g., the 'J-E' model). In the two-year time frame (~1958-60), Ed had a number of other PhD dissertation students whom I knew; these included Joe Eberly, Doug Scalapino, Baldwin Robertson, Larry Davis and Mike Duggan. My thesis work under Ed reminds me of a story about Michelangelo and his famous 'Pieta'. Michelangelo was an old man about then, so he hired a young craftsman to do much of the physical

    Representative sampling and adequate sample preparation are key factors for successful performance of further steps in foodomic analyses, as well as for correct data interpretation. Incorrect sampling and improper sample preparation can be sources of severe bias in foodomic analyses. It is well known that both wrong sampling and sample treatment cannot be corrected anymore. These, in the past frequently neglected facts, are now taken into consideration, and the progress in sampling and sample preparation in foodomics is reviewed here. We report the use of highly sophisticated instruments for both high-performance and high-throughput analyses, as well as miniaturization and the use of laboratory robotics in metabolomics, proteomics, peptidomics and genomics.

  18. Getting used to academic public speaking: global self-esteem predicts habituation in blood pressure response to repeated thesis presentations.

    Science.gov (United States)

    Elfering, Achim; Grebner, Simone

    2012-06-01

    Global self-esteem was tested to predict quicker cardiovascular adaptation during stressful oral thesis presentation and faster habituation from the first to the second and third thesis presentations. Nineteen graduate students initially rated their global self-esteem and afterwards orally presented their theses proposals in 20-min presentations to their thesis supervisor and peers. A second and third presentation of the revised thesis concepts took place at 4-weeks intervals. Ambulatory blood pressure and heart rate were assessed repeatedly during the presentations. Post-talk self ratings of stressfulness indicated presentations to be a strong public speaking stressor. One hundred and thirty-eight measurements of systolic (SBP), diastolic blood pressure (DBP), and heart rate (HR) showed a significant adaptation (decrease) during presentations. There was an overall mean level decrease from the first to the second, and the second to the third presentations in HR, but not in SBP and DBP. However, habituation in SBP and DBP across three presentations was significantly faster (p < .05) in those participants who initially reported higher levels of global self-esteem. Higher global self-esteem did not foster adaptation within the presentations. Self-esteem is discussed as an important individual resource that allows successful coping with recurring evaluative threats.

  2. The Radical Plasticity Thesis: How the Brain Learns to be Conscious

    Science.gov (United States)

    Cleeremans, Axel

    2011-01-01

    In this paper, I explore the idea that consciousness is something that the brain learns to do rather than an intrinsic property of certain neural states and not others. Starting from the idea that neural activity is inherently unconscious, the question thus becomes: How does the brain learn to be conscious? I suggest that consciousness arises as a result of the brain's continuous attempts at predicting not only the consequences of its actions on the world and on other agents, but also the consequences of activity in one cerebral region on activity in other regions. By this account, the brain continuously and unconsciously learns to redescribe its own activity to itself, so developing systems of meta-representations that characterize and qualify the target first-order representations. Such learned redescriptions, enriched by the emotional value associated with them, form the basis of conscious experience. Learning and plasticity are thus central to consciousness, to the extent that experiences only occur in experiencers that have learned to know they possess certain first-order states and that have learned to care more about certain states than about others. This is what I call the “Radical Plasticity Thesis.” In a sense thus, this is the enactive perspective, but turned both inwards and (further) outwards. Consciousness involves “signal detection on the mind”; the conscious mind is the brain's (non-conceptual, implicit) theory about itself. I illustrate these ideas through neural network models that simulate the relationships between performance and awareness in different tasks. PMID:21687455

    The importance of research, as promoted by the CanMEDS framework, is widely acknowledged. Many medical students in Germany work on a research project as part of their doctoral thesis whilst still going to medical school. However, a significant amount of projects are abandoned unfinished, which leads to substantial wastage of resources. One reason for this is an information deficit concerning undergraduate research projects. To counteract this, we introduced an annual event at LMU Munich called DoktaMed with more than 600 visitors each year. It combines medical convention and research fair including keynote lectures, workshops and poster sessions as well as an exhibition of research groups and institutes. DoktaMed is a peer-to-peer event organized by a team of 40 students. A needs analysis before its implementation underlined the information deficit as a possible cause for the high rate of abandoned projects. In the annual evaluation, visitors of DoktaMed rate the event with an average grade of 2.1 on a six-level Likert scale (n=558, SD=1.06, with "1=very good", "6=poor"). They stated to now feel better informed about the topic and regarded visiting DoktaMed as a worthwhile investment of time. Students are generally satisfied with the event and feel better informed after visiting DoktaMed. However, many students never visit DoktaMed for various reasons. A possible improvement would be to present a greater number of clinical studies in addition to the laboratory work that DoktaMed focuses on now. Evaluation after six years of DoktaMed is very promising. Visitors seem to be better informed. Nevertheless there is space for improvement in order to get more students and more faculty members involved. More studies are needed to assess long-term effects.

  5. Efficient modeling of interconnects and capacitive discontinuities in high-speed digital circuits. Thesis

    Oh, K. S.; Schutt-Aine, J.

    1995-01-01

    Modeling of interconnects and associated discontinuities with the recent advances high-speed digital circuits has gained a considerable interest over the last decade although the theoretical bases for analyzing these structures were well-established as early as the 1960s. Ongoing research at the present time is focused on devising methods which can be applied to more general geometries than the ones considered in earlier days and, at the same time, improving the computational efficiency and accuracy of these methods. In this thesis, numerically efficient methods to compute the transmission line parameters of a multiconductor system and the equivalent capacitances of various strip discontinuities are presented based on the quasi-static approximation. The presented techniques are applicable to conductors embedded in an arbitrary number of dielectric layers with two possible locations of ground planes at the top and bottom of the dielectric layers. The cross-sections of conductors can be arbitrary as long as they can be described with polygons. An integral equation approach in conjunction with the collocation method is used in the presented methods. A closed-form Green's function is derived based on weighted real images thus avoiding nested infinite summations in the exact Green's function; therefore, this closed-form Green's function is numerically more efficient than the exact Green's function. All elements associated with the moment matrix are computed using the closed-form formulas. Various numerical examples are considered to verify the presented methods, and a comparison of the computed results with other published results showed good agreement.

  6. A thesis investigating the impact of energy related environmental factors on domestic window design

    Science.gov (United States)

    McEvoy, Michael Edward

    In recent years the extent of glazing in houses has been tightly controlled by the Building Regulations in order to save energy. In addition guidelines derived from passive solar principles prescribe the distribution of domestic windows between elevations according to their orientation. This thesis studies the impact of these energy-related environmental factors on domestic window design. The first of these investigations determined the degree to which limitations on the area and arrangement of windows are significant in terms of daylighting. The experiments measured the effect that passive solar requirements and detailed aspects of window design have on the quality of daylighting in houses. The volume of background ventilation required for domestic accommodation has recently been increased. As a result, in a well-sealed construction, heat loss due to background ventilation becomes a larger part of the total heat loss and larger air movements become a potential cause of draughts. The ventilation experiment sought to establish the impact of these more onerous requirements on comfort within rooms. The third experiment combines these factors and asks the question: Could windows be actively involved in overcoming some of these difficulties by being used to preheat ventilation air in order to diminish the extent of heat loss and to alleviate the problem of cold draughts? Also by designing the window to reclaim heat from the room might it be possible to offset the window's thermal inadequacy? Through analysis of responses to a questionnaire and the use of optimisation techniques, scenarios were suggested for the future modification of windows in relation to energy and health expectations. The conclusions form a commentary on recent and future revisions to the Building Regulations and determine whether or not the Regulations facilitate the environmental engineering of windows as an active component of a building's whole environmental system.

  8. Analysing and Comparing Encodability Criteria

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Encodings or the proof of their absence are the main way to compare process calculi. To analyse the quality of encodings and to rule out trivial or meaningless encodings, they are augmented with quality criteria. There exists a bunch of different criteria and different variants of criteria in order to reason in different settings. This leads to incomparable results. Moreover it is not always clear whether the criteria used to obtain a result in a particular setting do indeed fit to this setting. We show how to formally reason about and compare encodability criteria by mapping them on requirements on a relation between source and target terms that is induced by the encoding function. In particular we analyse the common criteria full abstraction, operational correspondence, divergence reflection, success sensitiveness, and respect of barbs; e.g. we analyse the exact nature of the simulation relation (coupled simulation versus bisimulation that is induced by different variants of operational correspondence. This way we reduce the problem of analysing or comparing encodability criteria to the better understood problem of comparing relations on processes.

    James, Adrian Martin

    This thesis describes the design and development of the FONEMA instrument to be flown aboard the Russian mission to Mars in 1996. Many probes have flown to Mars yet despite this many mysteries still remain, among them the nature of the interaction of the solar wind with the planetary obstacle. In this thesis I will present some of the results from earlier spacecraft and the models of the interaction that they suggest paying particular attention to the contribution of ion analysers. From these results it will become clear that a fast ion sensor is needed to resolve many of the questions about the magnetosphere of Mars. The FONEMA instrument was designed for this job making use of a novel electrostatic mirror and particle collimator combined with parallel magnetic and electrostatic fields to resolve the ions into mass and energy bins. Development and production of the individual elements is discussed in detail.

  18. Method for optimizing resource allocation in a government organization. Ph.D. Thesis

    Afarin, James

    1994-01-01

    The managers in Federal agencies are challenged to control the extensive activities in government and still provide high-quality products and services to the American taxpayers. Considering today's complex social and economic environment and the $3.8 billion daily cost of operating the Federal Government, it is evident that there is a need to develop decision-making tools for accurate resource allocation and total quality management. The goal of this thesis is to provide a methodical process that will aid managers in Federal Government to make budgetary decisions based on the cost of services, the agency's objectives, and the customers' perception of the agency's product. A general resource allocation procedure was developed in this study that can be applied to any government organization. A government organization, hereafter the 'organization,' is assumed to be a multidivision enterprise. This procedure was applied to a small organization for the proof of the concept. This organization is the Technical Services Directorate (TSD) at the NASA Lewis Research Center in Cleveland, Ohio. As part of the procedure, a nonlinear programming model was developed to account for the resources of the organization, the outputs produced by the organization, the decision-maker's views, and the customers' satisfaction with the organization. The information on the resources of the organization was acquired from current budget levels of the organization and the human resources assigned to the divisions. The outputs of the organization were defined and measured by identifying metrics that assess the outputs, the most challenging task in this study. The decision-maker's views are represented in the model as weights assigned to the various outputs and were quantified by using the analytic hierarchy process. The customer's opinions regarding the outputs of the organization were collected through questionnaires that were designed for each division individually. Following the philosophy of

  5. Optical characterization of OLED emitter properties by radiation pattern analyses

    Energy Technology Data Exchange (ETDEWEB)

    Flaemmich, Michael

    2011-09-08

    Researches in both, academia and industry are investigating optical loss channels in OLED layered systems by means of optical simulation tools in order to derive promising concepts for a further enhancement of the overall device performance. Besides other factors, the prospects of success of such optimization strategies rely severely on the credibility of the optical input data. The present thesis provides a guideline to measure the active optical properties of OLED emitter materials in situ by radiation pattern analyses. Reliable and widely applicable methods are introduced to determine the internal electroluminescence spectrum, the profile of the emission zone, the dipole emitter orientation, and the internal luminescence quantum efficiency of emissive materials from the optical far field emission of OLEDs in electrical operation. The proposed characterization procedures are applied to sets of OLEDs containing both, fluorescent polymeric materials as well as phosphorescent small-molecular emitters, respectively. On the one hand, quite expected results are obtained. On the other hand, several novel and truly surprising results are found. Most importantly, this thesis contains the first report of a non-isotropic, mainly parallel emitter orientation in a phosphorescent small-molecular guest-host system (Ir(MDQ)2(acac) in a-NPD). Due to the latter result, emitter orientation based optimization of phosphorescent OLEDs seems to be within reach. Since parallel dipoles emit preferably into air, the utilization of smart emissive materials with advantageous molecular orientation is capable to boost the efficiency of phosphorescent OLEDs by 50%. Materials design, the influence of the matrix material and the substrate, as well as film deposition conditions are just a few parameters that need to be studied further in order to exploit the huge potential of the dipole emitter orientation in phosphorescent OLEDs.

  6. Managing risk and marginalizing identities: on the society-of-captives thesis and the harm of social dis-ease.

    Arrigo, Bruce A

    2013-06-01

    This article develops the constitutive features of the society-of-captives thesis as suggested by Arrigo and Milovanovic, and Arrigo, Bersot, and Sellers. The relevance of this thesis is briefly explored in relation to the institutional and community-based treatment philosophies that currently inform the mental health and criminal justice systems. This exploration specifies how risk (being human and doing humanness differently) is managed symbolically, linguistically, materially, and culturally. The management of this risk extends to the kept as well as to their keepers, regulators, and watchers (i.e., the society of captives). This article calls for a new clinical praxis (being/doing a critical mindfulness) designed to overcome the totalizing madness (the harm of social dis-ease) that follows from managing risk fearfully and marginalizing identities desperately as reified recursively through society's captivity. The ethical underpinnings of this clinical praxis represent an emergent direction for undertaking correctional policy reform.

An important part of work was performed also in solving of scientific and technical tasks appointed within bilateral projects of co-operation between UJD and its international partnership organisations as well as within international projects ordered and financed by the European Commission. All these activities served as an independent support for UJD in its deterministic and probabilistic safety assessment of nuclear installations. A special attention was paid to a review of probabilistic safety assessment study of level 1 for NPP Mochovce. The probabilistic safety analysis of NPP related to the full power operation was elaborated in the study and a contribution of the technical and operational improvements to the risk decreasing was quantified. A core damage frequency of the reactor was calculated and the dominant initiating events and accident sequences with the major contribution to the risk were determined. The target of the review was to determine the acceptance of the sources of input information, assumptions, models, data, analyses and obtained results, so that the probabilistic model could give a real picture of the NPP. The review of the study was performed in co-operation of UJD with the IAEA (IPSART mission) as well as with other external organisations, which were not involved in the elaboration of the reviewed document and probabilistic model of NPP. The review was made in accordance with the IAEA guidelines and methodical documents of UJD and US NRC. In the field of calculation safety analyses the UJD activity was focused on the analysis of an operational event, analyses of the selected accident scenarios

    This article provides an in-depth analysis of the wrongness of killing by comparing different versions of three influential views: the traditional view that killing is always wrong; the liberal view that killing is wrong if and only if the victim does not want to be killed; and Don Marquis‟ future...... of value account of the wrongness of killing. In particular, I illustrate the advantages that a basic version of the liberal view and a basic version of the future of value account have over competing alternatives. Still, ultimately none of the views analysed here are satisfactory; but the different...

  11. Methodological challenges in carbohydrate analyses

    2007-07-01

    Full Text Available Carbohydrates can provide up to 80% of the dry matter in animal diets, yet their specific evaluation for research and diet formulation is only now becoming a focus in the animal sciences. Partitioning of dietary carbohydrates for nutritional purposes should reflect differences in digestion and fermentation characteristics and effects on animal performance. Key challenges to designating nutritionally important carbohydrate fractions include classifying the carbohydrates in terms of nutritional characteristics, and selecting analytical methods that describe the desired fraction. The relative lack of information on digestion characteristics of various carbohydrates and their interactions with other fractions in diets means that fractions will not soon be perfectly established. Developing a system of carbohydrate analysis that could be used across animal species could enhance the utility of analyses and amount of data we can obtain on dietary effects of carbohydrates. Based on quantities present in diets and apparent effects on animal performance, some nutritionally important classes of carbohydrates that may be valuable to measure include sugars, starch, fructans, insoluble fiber, and soluble fiber. Essential to selection of methods for these fractions is agreement on precisely what carbohydrates should be included in each. Each of these fractions has analyses that could potentially be used to measure them, but most of the available methods have weaknesses that must be evaluated to see if they are fatal and the assay is unusable, or if the assay still may be made workable. Factors we must consider as we seek to analyze carbohydrates to describe diets: Does the assay accurately measure the desired fraction? Is the assay for research, regulatory, or field use (affects considerations of acceptable costs and throughput? What are acceptable accuracy and variability of measures? Is the assay robust (enhances accuracy of values? For some carbohydrates, we

    Full Text Available This is a report of a study designed to examine the process of thesis—a final (research-based paper for undergrads prior to academic completion—writing of English Department students who graduated in Academic Year 2007/2008. Using a descriptive method, this case study aimed to describe the stages, to identify the problems, and to explore the techniques of solving problems used by respondents in the thesis writing by involving six students who had engaged in writing and research project course. The data concerning writing stages, problems, and coping with strategies were collected by using questionnaires, interviews, and documentation (thesis. The results showed that all participants went through the thesis writing stages determined by Faculty of Adab of UIN Sunan Gunung Djati, Bandung, namely: 1 Starting process; 2 Researching; 3 Reporting; and 4 Doing consultation. These also showed that all respondents encountered: 1 Procedural problems, which were likely to be the major problems shared by all respondents; 2 Academic problems; and 3 Nonacademic problems. However, whatever problems they dealt with, each of them had his/her own strategies to cope with. The procedural and academic problems were coped with by reading, doing consultation, and peer-collaboration. Meanwhile, non-academic problems were solved by having a rest and managing time.

    2008-12-01

    '"Forman thesis', published in 1971, argued for a historical linkage among the intellectual atmosphere of Weimar Germany, popular revolts against determinism and materialism, and the creation of the revolutionary new theory of quantum mechanics. Paul Forman's long essay on "Weimar Culture" has shaped research agendas in numerous fields, from the history and philosophy of physics to German history to the sociology of scientific knowledge. Despite its status as a classic and its transformative effect, Weimar Culture has always inspired as much critique as assent. In particular in the history of science, cohorts of students and two generations of scholars have debated the Forman thesis as a conceptual tool for linking scientific change with cultural processes. The Forman thesis raises critical questions for both the ongoing debates over cultural approaches to the history of science and the burgeoning newer scholarship on physics in and beyond Weimar Germany. Exploring these implications has been the aim of a transnational project of the three authors of this article which sheds some light on these debates and briefly introduces the following papers of this special issue devoted to Paul Forman and his seminal works in the history of science.

    2012-01-01

    Full Text Available Traditionally, the development of oral feeding is viewed as a continuous, unitary process in which reflex-dominated sucking behavior gives rise to a more varied and volitional feeding behavior. In contrast, we consider the thesis that the infant develops two separable ingestive systems, one for suckling and one for feeding. First, we apply an evolutionary perspective, recognizing that suckling-feeding is a universal, mammalian developmental sequence. We find that in mammalian evolution, feeding systems in offspring were established prior to the evolution of lactation, and therefore suckling is a separable feature that was added to feeding. We next review an experimental literature that characterizes suckling and feeding as separable in terms of their topography, sensory controls, physiological controls, neural substrates, and experience-based development. Together, these considerations constitute a view of “dual ingestive systems.” The thesis, then, is that suckling is not a simple precursor of feeding but is a complete behavior that emerges, forms, and then undergoes a dissolution that overlaps with the emergence of independent feeding. This thesis guides us to focus differently on the challenges of properly managing and facilitating oral ingestion in infants, especially those born preterm, prior to the developmental onset of suckling.

  19. Theorising and Analysing Academic Labour

    Directory of Open Access Journals (Sweden)

    Thomas Allmer

    2018-01-01

    Full Text Available The aim of this article is to contextualise universities historically within capitalism and to analyse academic labour and the deployment of digital media theoretically and critically. It argues that the post-war expansion of the university can be considered as medium and outcome of informational capitalism and as a dialectical development of social achievement and advanced commodification. The article strives to identify the class position of academic workers, introduces the distinction between academic work and labour, discusses the connection between academic, information and cultural work, and suggests a broad definition of university labour. It presents a theoretical model of working conditions that helps to systematically analyse the academic labour process and to provide an overview of working conditions at universities. The paper furthermore argues for the need to consider the development of education technologies as a dialectics of continuity and discontinuity, discusses the changing nature of the forces and relations of production, and the impact on the working conditions of academics in the digital university. Based on Erik Olin Wright’s inclusive approach of social transformation, the article concludes with the need to bring together anarchist, social democratic and revolutionary strategies for establishing a socialist university in a commons-based information society.

  20. CFD analyses in regulatory practice

    2012-01-01

    Numerical software is used in nuclear regulatory procedures for many problems in the fields of neutron physics, structural mechanics, thermal hydraulics etc. Among other things, the software is employed in dimensioning and designing systems and components and in simulating transients and accidents. In nuclear technology, analyses of this kind must meet strict requirements. Computational Fluid Dynamics (CFD) codes were developed for computing multidimensional flow processes of the type occurring in reactor cooling systems or in containments. Extensive experience has been accumulated by now in selected single-phase flow phenomena. At the present time, there is a need for development and validation with respect to the simulation of multi-phase and multi-component flows. As insufficient input by the user can lead to faulty results, the validity of the results and an assessment of uncertainties are guaranteed only through consistent application of so-called Best Practice Guidelines. The authors present the possibilities now available to CFD analyses in nuclear regulatory practice. This includes a discussion of the fundamental requirements to be met by numerical software, especially the demands upon computational analysis made by nuclear rules and regulations. In conclusion, 2 examples are presented of applications of CFD analysis to nuclear problems: Determining deboration in the condenser reflux mode of operation, and protection of the reactor pressure vessel (RPV) against brittle failure.

  2. Hydrogen Analyses in the EPR

    2008-01-01

    In severe accidents with core melting large amounts of hydrogen may be released into the containment. The EPR provides a combustible gas control system to prevent hydrogen combustion modes with the potential to challenge the containment integrity due to excessive pressure and temperature loads. This paper outlines the approach for the verification of the effectiveness and efficiency of this system. Specifically, the justification is a multi-step approach. It involves the deployment of integral codes, lumped parameter containment codes and CFD codes and the use of the sigma criterion, which provides the link to the broad experimental data base for flame acceleration (FA) and deflagration to detonation transition (DDT). The procedure is illustrated with an example. The performed analyses show that hydrogen combustion at any time does not lead to pressure or temperature loads that threaten the containment integrity of the EPR. (authors)

    Hanford Environmental Dose Reconstruction (HEDR) Project staff are developing mathematical models to be used to estimate the radiation dose that individuals may have received as a result of emissions since 1944 from the US Department of Energy's (DOE) Hanford Site near Richland, Washington. An uncertainty and sensitivity analyses plan is essential to understand and interpret the predictions from these mathematical models. This is especially true in the case of the HEDR models where the values of many parameters are unknown. This plan gives a thorough documentation of the uncertainty and hierarchical sensitivity analysis methods recommended for use on all HEDR mathematical models. The documentation includes both technical definitions and examples. In addition, an extensive demonstration of the uncertainty and sensitivity analysis process is provided using actual results from the Hanford Environmental Dose Reconstruction Integrated Codes (HEDRIC). This demonstration shows how the approaches used in the recommended plan can be adapted for all dose predictions in the HEDR Project

  7. Analysing performance through value creation

    Adrian TRIFAN

    2015-12-01

    Full Text Available This paper draws a parallel between measuring financial performance in 2 variants: the first one using data offered by accounting, which lays emphasis on maximizing profit, and the second one which aims to create value. The traditional approach to performance is based on some indicators from accounting data: ROI, ROE, EPS. The traditional management, based on analysing the data from accounting, has shown its limits, and a new approach is needed, based on creating value. The evaluation of value based performance tries to avoid the errors due to accounting data, by using other specific indicators: EVA, MVA, TSR, CVA. The main objective is shifted from maximizing the income to maximizing the value created for shareholders. The theoretical part is accompanied by a practical analysis regarding the creation of value and an analysis of the main indicators which evaluate this concept.

In this thesis we address the problem of understanding the semantics of access control policy language XACML, in particular XACML version 3.0....... The main focus of this thesis is modelling and analysing access control policies in XACML 3.0. There are two main contributions in this thesis. First, we study and formalise XACML 3.0, in particular the Policy Decision Point (PDP). The concrete syntax of XACML is based on the XML format, while its standard...... semantics is described normatively using natural language. The use of English text in standardisation leads to the risk of misinterpretation and ambiguity. In order to avoid this drawback, we define an abstract syntax of XACML 3.0 and a formal XACML semantics. Second, we propose a logic-based XACML analysis...

    We are compiling the most comprehensive database of M dwarfs ever built, CARMENCITA, the CARMENES Cool dwarf Information and daTa Archive, which will be the CARMENES 'input catalogue'. In addition to the science preparation with low- and high-resolution spectrographs and lucky imagers, we compile a huge pile of public data on over 2200 M dwarfs, and analyse them, mostly using virtual-observatory tools. Here we describe four specific actions carried out by master students. They mine public archives for additional high-resolution spectroscopy (UVES, FEROS and HARPS), multi-band photometry (FUV-NUV-u-B-g-V-r-R-i-J-H-Ks-W1-W2-W3-W4), X-ray data (ROSAT, XMM-Newton and Chandra), and periods, rotational velocities and Hα pseudo-equivalent widths. As described, there are many interdependences between all these data.

    Alexander, Keith; Taylor, Alexander J.; Dennis, Mark R.

    2017-02-01

    Long, flexible physical filaments are naturally tangled and knotted, from macroscopic string down to long-chain molecules. The existence of knotting in a filament naturally affects its configuration and properties, and may be very stable or disappear rapidly under manipulation and interaction. Knotting has been previously identified in protein backbone chains, for which these mechanical constraints are of fundamental importance to their molecular functionality, despite their being open curves in which the knots are not mathematically well defined; knotting can only be identified by closing the termini of the chain somehow. We introduce a new method for resolving knotting in open curves using virtual knots, which are a wider class of topological objects that do not require a classical closure and so naturally capture the topological ambiguity inherent in open curves. We describe the results of analysing proteins in the Protein Data Bank by this new scheme, recovering and extending previous knotting results, and identifying topological interest in some new cases. The statistics of virtual knots in protein chains are compared with those of open random walks and Hamiltonian subchains on cubic lattices, identifying a regime of open curves in which the virtual knotting description is likely to be important.

  13. Digital image analyser for autoradiography

    1985-01-01

    The most critical parameter in quantitative autoradiography for assay of tissue concentrations of tracers is the ability to obtain precise and accurate measurements of optical density of the images. Existing high precision systems for image analysis, rotating drum densitometers, are expensive, suffer from mechanical problems and are slow. More moderately priced and reliable video camera based systems are available, but their outputs generally do not have the uniformity and stability necessary for high resolution quantitative autoradiography. The authors have designed and constructed an image analyser optimized for quantitative single and multiple tracer autoradiography which the authors refer to as a memory-mapped charged-coupled device scanner (MM-CCD). The input is from a linear array of CCD's which is used to optically scan the autoradiograph. Images are digitized into 512 x 512 picture elements with 256 gray levels and the data is stored in buffer video memory in less than two seconds. Images can then be transferred to RAM memory by direct memory-mapping for further processing. Arterial blood curve data and optical density-calibrated standards data can be entered and the optical density images can be converted automatically to tracer concentration or functional images. In double tracer studies, images produced from both exposures can be stored and processed in RAM to yield ''pure'' individual tracer concentration or functional images. Any processed image can be transmitted back to the buffer memory to be viewed on a monitor and processed for region of interest analysis

    Recriticality in a BWR has been studied for a total loss of electric power accident scenario. In a BWR, the B{sub 4}C control rods would melt and relocate from the core before the fuel during core uncovery and heat-up. If electric power returns during this time-window unborated water from ECCS systems will start to reflood the partly control rod free core. Recriticality might take place for which the only mitigating mechanisms are the Doppler effect and void formation. In order to assess the impact of recriticality on reactor safety, including accident management measures, the following issues have been investigated in the SARA project: 1. the energy deposition in the fuel during super-prompt power burst, 2. the quasi steady-state reactor power following the initial power burst and 3. containment response to elevated quasi steady-state reactor power. The approach was to use three computer codes and to further develop and adapt them for the task. The codes were SIMULATE-3K, APROS and RECRIT. Recriticality analyses were carried out for a number of selected reflooding transients for the Oskarshamn 3 plant in Sweden with SIMULATE-3K and for the Olkiluoto 1 plant in Finland with all three codes. The core state initial and boundary conditions prior to recriticality have been studied with the severe accident codes SCDAP/RELAP5, MELCOR and MAAP4. The results of the analyses show that all three codes predict recriticality - both superprompt power bursts and quasi steady-state power generation - for the studied range of parameters, i. e. with core uncovery and heat-up to maximum core temperatures around 1800 K and water flow rates of 45 kg/s to 2000 kg/s injected into the downcomer. Since the recriticality takes place in a small fraction of the core the power densities are high which results in large energy deposition in the fuel during power burst in some accident scenarios. The highest value, 418 cal/g, was obtained with SIMULATE-3K for an Oskarshamn 3 case with reflooding

Since recriticality takes place in a small fraction of the core, the power densities are high, which results in large energy deposition in the fuel during power burst in some accident scenarios. The highest value, 418 cal g{sup -1}, was obtained with SIMULATE-3K for an Oskarshamn 3 case with reflooding rate of 2000 kg s{sup -1}. In most cases, however, the predicted energy deposition was smaller, below the regulatory limits for fuel failure, but close to or above recently observed thresholds for fragmentation and dispersion of high burn-up fuel.

    Recriticality in a BWR during reflooding of an overheated partly degraded core, i.e. with relocated control rods, has been studied for a total loss of electric power accident scenario. In order to assess the impact of recriticality on reactor safety, including accident management strategies, the following issues have been investigated in the SARA project: (1) the energy deposition in the fuel during super-prompt power burst; (2) the quasi steady-state reactor power following the initial power burst; and (3) containment response to elevated quasi steady-state reactor power. The approach was to use three computer codes and to further develop and adapt them for the task. The codes were SIMULATE-3K, APROS and RECRIT. Recriticality analyses were carried out for a number of selected reflooding transients for the Oskarshamn 3 plant in Sweden with SIMULATE-3K and for the Olkiluoto 1 plant in Finland with all three codes. The core initial and boundary conditions prior to recriticality have been studied with the severe accident codes SCDAP/RELAP5, MELCOR and MAAP4.

    Recriticality in a BWR has been studied for a total loss of electric power accident scenario. In a BWR, the B 4 C control rods would melt and relocate from the core before the fuel during core uncovery and heat-up. If electric power returns during this time-window unborated water from ECCS systems will start to reflood the partly control rod free core. Recriticality might take place for which the only mitigating mechanisms are the Doppler effect and void formation. In order to assess the impact of recriticality on reactor safety, including accident management measures, the following issues have been investigated in the SARA project: 1. the energy deposition in the fuel during super-prompt power burst, 2. the quasi steady-state reactor power following the initial power burst and 3. containment response to elevated quasi steady-state reactor power. The approach was to use three computer codes and to further develop and adapt them for the task. The codes were SIMULATE-3K, APROS and RECRIT. Recriticality analyses were carried out for a number of selected reflooding transients for the Oskarshamn 3 plant in Sweden with SIMULATE-3K and for the Olkiluoto 1 plant in Finland with all three codes. The core state initial and boundary conditions prior to recriticality have been studied with the severe accident codes SCDAP/RELAP5, MELCOR and MAAP4. The results of the analyses show that all three codes predict recriticality - both superprompt power bursts and quasi steady-state power generation - for the studied range of parameters, i. e. with core uncovery and heat-up to maximum core temperatures around 1800 K and water flow rates of 45 kg/s to 2000 kg/s injected into the downcomer. Since the recriticality takes place in a small fraction of the core the power densities are high which results in large energy deposition in the fuel during power burst in some accident scenarios. The highest value, 418 cal/g, was obtained with SIMULATE-3K for an Oskarshamn 3 case with reflooding

    To evaluate associations between sensations of ocular itch and dry eye (DE) symptoms, including ocular pain, and DE signs. A cross-sectional study of 324 patients seen in the Miami Veterans Affairs eye clinic was performed. The evaluation consisted of questionnaires regarding ocular itch, DE symptoms, descriptors of neuropathic-like ocular pain (NOP), and evoked pain sensitivity testing on the forehead and forearm, followed by a comprehensive ocular surface examination including corneal mechanical sensitivity testing. Analyses were performed to examine for differences between those with and without subjective complaints of ocular itch. The mean age was 62 years with 92% being male. Symptoms of DE and NOP were more frequent in patients with moderate-severe ocular itch compared to those with no or mild ocular itch symptoms. With the exception of ocular surface inflammation (abnormal matrix metalloproteinase 9 testing) which was less common in those with moderate-severe ocular itch symptoms, DE signs were not related to ocular itch. Individuals with moderate-severe ocular itch also demonstrated greater sensitivity to evoked pain on the forearm and had higher non-ocular pain, depression, and post-traumatic stress disorders scores, compared to those with no or mild itch symptoms. Subjects with moderate-severe ocular itch symptoms have more severe symptoms of DE, NOP, non-ocular pain and demonstrate abnormal somatosensory testing in the form of increased sensitivity to evoked pain at a site remote from the eye, consistent with generalized hypersensitivity.

    Full Text Available Carbon nanotubes (CNTs were synthesized by a catalytic chemical vapor deposition method (CCVD of ethylene over alumina and silica supported bimetallic catalysts based on Fe, Co and Ni. The catalysts were prepared by a precipitation method, calcined at 600 °C and in situ reduced in hydrogen flow at 700 °C. The CNTs growth was carried out by a flow the mixture of C2H4 and nitrogen over the catalyst powder in a horizontal oven. The structure and morphology of as-synthesized CNTs were characterized using SEM. The as-synthesized nanotubes were purified by acid and basic treatments in order to remove impurities such as amorphous carbon, graphite nanoparticles and metal catalysts. XRD and DTA/TG analyses showed that the amounts of by-products in the purified CNTs samples were reduced significantly. According to the observed results, ethylene is an active carbon source for growing high-density CNTs with high yield but more on alumina-supported catalysts than on their silica- supported counterparts. The last might be explained by SMSI formed in the case of alumina-supported catalysts, resulting in higher active phase dispersion.

    1991-01-01

    An advanced implementation of the direct boundary element method (BEM) applicable to free-vibration, periodic (steady-state) vibration and linear and nonlinear transient dynamic problems involving two and three-dimensional isotropic solids of arbitrary shape is presented. Interior, exterior, and half-space problems can all be solved by the present formulation. For the free-vibration analysis, a new real variable BEM formulation is presented which solves the free-vibration problem in the form of algebraic equations (formed from the static kernels) and needs only surface discretization. In the area of time-domain transient analysis, the BEM is well suited because it gives an implicit formulation. Although the integral formulations are elegant, because of the complexity of the formulation it has never been implemented in exact form. In the present work, linear and nonlinear time domain transient analysis for three-dimensional solids has been implemented in a general and complete manner. The formulation and implementation of the nonlinear, transient, dynamic analysis presented here is the first ever in the field of boundary element analysis. Almost all the existing formulation of BEM in dynamics use the constant variation of the variables in space and time which is very unrealistic for engineering problems and, in some cases, it leads to unacceptably inaccurate results. In the present work, linear and quadratic isoparametric boundary elements are used for discretization of geometry and functional variations in space. In addition, higher order variations in time are used. These methods of analysis are applicable to piecewise-homogeneous materials, such that not only problems of the layered media and the soil-structure interaction can be analyzed but also a large problem can be solved by the usual sub-structuring technique. The analyses have been incorporated in a versatile, general-purpose computer program. Some numerical problems are solved and, through comparisons

    Although Kraepelin and his oeuvre have been in scientific focus over the past decades, main aspects have still been neglected. Thus the exact circumstances under which and on what topic Kraepelin wrote his habilitation thesis and qualified as university lecturer (in Germany the prerequisite to be appointed as professor) are still widely unknown. This study reconstructs his habilitation at the Medical Faculty of Leipzig University in 1882. The study reveals the difficulties he had to habilitate on a topic from Wilhelm Wundt's experimental psychology and the opposition he faced from Paul Flechsig. Yet Kraepelin succeeded, mainly due to a positive review by neurologist Wilhelm Erb on his study "On the Influence of Acute Diseases on the Development of Mental Illnesses" (1881/82). This work must be regarded as his actual habilitation thesis. It provides an update of organic psychiatric disorders following acute inflammatory diseases and a meta-analysis on the basis of raw data. In addition it discusses possibilities to categorize and understand the pathophysiological mechanism of these disorders and to classify them into those appearing when the fever rises and those occurring when it falls, which has a high impact from a very modern psychoimmunological viewpoint.

    Pawnee Nation of Oklahoma Energy Option Analyses In 2003, the Pawnee Nation leadership identified the need for the tribe to comprehensively address its energy issues. During a strategic energy planning workshop a general framework was laid out and the Pawnee Nation Energy Task Force was created to work toward further development of the tribe’s energy vision. The overarching goals of the “first steps” project were to identify the most appropriate focus for its strategic energy initiatives going forward, and to provide information necessary to take the next steps in pursuit of the “best fit” energy options. Description of Activities Performed The research team reviewed existing data pertaining to the availability of biomass (focusing on woody biomass, agricultural biomass/bio-energy crops, and methane capture), solar, wind and hydropower resources on the Pawnee-owned lands. Using these data, combined with assumptions about costs and revenue streams, the research team performed preliminary feasibility assessments for each resource category. The research team also reviewed available funding resources and made recommendations to Pawnee Nation highlighting those resources with the greatest potential for financially-viable development, both in the near-term and over a longer time horizon. Findings and Recommendations Due to a lack of financial incentives for renewable energy, particularly at the state level, combined mediocre renewable energy resources, renewable energy development opportunities are limited for Pawnee Nation. However, near-term potential exists for development of solar hot water at the gym, and an exterior wood-fired boiler system at the tribe’s main administrative building. Pawnee Nation should also explore options for developing LFGTE resources in collaboration with the City of Pawnee. Significant potential may also exist for development of bio-energy resources within the next decade. Pawnee Nation representatives should closely monitor

    Full Text Available This paper aims to discuss the comparative terms of arsis and thesis in the study of Western music. The purpose of the study is to study the forms of music from the terms of language and its application, because there are many elements of music that are not understandable. Method of this study uses classical literature and musicology approach in which the great phrase rhythm of Gregorian music was more appropriately take a literary term; arsis and thesis. The focus of this study is to discuss the terms of Arsis and Thesis used in the section of rhythm elements of non-traditional music. This study reveals several musical terms in which there are similarities and differences between the rhythm and bars of music. The similarities and differences in the analysis are based on the history of Western music from Gregorian music. Gregorian was monophonic music that still existed in Europe until the 19th century. There were only two phrases in Gregorian music; when the melody moved up and when it moved down. In this case, there were two main elements in Gregorian music; they were different in rhythmic and they were in one rhythm of music. Arsis is a hard melody while thesis is a soft melody. It could be said that arsis and thesis are also parts of the dynamics form of music work. Keywords: arsis; Thesis; music rhythm; non-traditional music.

  8. Dynamics of energy systems: Methods of analysing technology change

    Energy Technology Data Exchange (ETDEWEB)

    Neij, Lena

    1999-05-01

    Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. Two types of methods have been considered, methods of analysing and projecting the dynamics of future technology change and methods of evaluating policy instruments effecting technology change, i.e. market transformation programmes. Two methods are focused on analysing the dynamics of future technology change; vintage models and experience curves. Vintage models, which allow for complex analysis of annual streams of energy and technological investments, are applied to the analysis of the time dynamics of electricity demand for lighting and air-distribution in Sweden. The results of the analyses show that the Swedish electricity demand for these purposes could decrease over time, relative to a reference scenario, if policy instruments are used. Experience curves are used to provide insight into the prospects of diffusion of wind turbines and photo voltaic (PV) modules due to cost reduction. The results show potential for considerable cost reduction for wind-generated electricity, which, in turn, could lead to major diffusion of wind turbines. The results also show that major diffusion of PV modules, and a reduction of PV generated electricity down to the level of conventional base-load electricity, will depend on large investments in bringing the costs down (through R D and D, market incentives and investments in niche markets) or the introduction of new generations of PV modules (e.g. high-efficiency mass-produced thin-film cells). Moreover, a model has been developed for the evaluation of market transformation programmes, i.e. policy instruments that effect technology change and the introduction and commercialisation of energy

    2014-01-01

    The purpose of this thesis is to improve the photon selection of the CMS SinglePhoton search for Supersymmetry by using multivariate analyses.The Single-Photon search aims to find Supersymmetry (SUSY) in data taken by theCompact Muon Solenoid (CMS) detector at the Large Hadron Collider located atthe research center CERN. SUSY is an extension of the standard model of particlephysics. The search is designed for a general gauge mediation scenario, which describes the gauge mediated SUSY breaking. The analysis uses final states with jets,at least one photon and missing transverse energy. A data-driven prediction of themultijet background is performed for the analysis. For this purpose, photon candidates have to be classified into two selections.In this thesis the usage of multivariate analyses for the photon candidate classification is studied. The methods used are Fisher Discriminant, Boosted Decision Treesand Artificial Neural Networks. Their performance is evaluated with respect to different aspects impor...

  11. Analysing Smart Metering Systems from a Consumer Perspective

    Science.gov (United States)

    Yesudas, Rani

    Many countries are deploying smart meters and Advanced Metering Infrastructure systems as part of demand management and grid modernisation efforts. Several of these projects are facing consumer resistance. The advertised benefits to the consumer appear mainly monetary but detailed analysis shows that financial benefits are hard to realise since the fixed services charges are high. Additionally, the data collected from smart meters have security and privacy implications for the consumer. These projects failed to consider end-users as an important stakeholder group during planning stages resulting in the design and roll-out of expensive systems, which do not demonstrate clear consumer benefits. The overall goal of the research reported in this thesis was to improve the smart metering system to deliver consumer benefits that increase confidence and acceptance of these projects. The smart metering system was examined from an end-user perspective for realistic insights into consumer concerns. Processes from Design Science Research methodology were utilised to conduct this research due to the utilitarian nature of the objective. Consumer segmentation was central to the proposed measures. Initially, a consumer-friendly risk analysis framework was devised, and appropriate requirement elicitation techniques were identified. Control options for smart meter data transfer and storage were explored. Various scenarios were analysed to determine consumer-friendly features in the smart metering system, including control options for smart meter data transfer and storage. Proposed functionalities (billing choices, feedback information and specific configurations to match the needs of different user segments) were studied using the Australian smart metering system. Smart meters vary in capabilities depending on the manufacturer, mode and place of deployment. The research showed that features proposed in this thesis are implementable in smart meters, by examining their applicability

  15. Models for transient analyses in advanced test reactors

    International Nuclear Information System (INIS)

    Gabrielli, Fabrizio

    2011-01-01

    Several strategies are developed worldwide to respond to the world's increasing demand for electricity. Modern nuclear facilities are under construction or in the planning phase. In parallel, advanced nuclear reactor concepts are being developed to achieve sustainability, minimize waste, and ensure uranium resources. To optimize the performance of components (fuels and structures) of these systems, significant efforts are under way to design new Material Test Reactors facilities in Europe which employ water as a coolant. Safety provisions and the analyses of severe accidents are key points in the determination of sound designs. In this frame, the SIMMER multiphysics code systems is a very attractive tool as it can simulate transients and phenomena within and beyond the design basis in a tightly coupled way. This thesis is primarily focused upon the extension of the SIMMER multigroup cross-sections processing scheme (based on the Bondarenko method) for a proper heterogeneity treatment in the analyses of water-cooled thermal neutron systems. Since the SIMMER code was originally developed for liquid metal-cooled fast reactors analyses, the effect of heterogeneity had been neglected. As a result, the application of the code to water-cooled systems leads to a significant overestimation of the reactivity feedbacks and in turn to non-conservative results. To treat the heterogeneity, the multigroup cross-sections should be computed by properly taking account of the resonance self-shielding effects and the fine intra-cell flux distribution in space group-wise. In this thesis, significant improvements of the SIMMER cross-section processing scheme are described. A new formulation of the background cross-section, based on the Bell and Wigner correlations, is introduced and pre-calculated reduction factors (Effective Mean Chord Lengths) are used to take proper account of the resonance self-shielding effects of non-fuel isotopes. Moreover, pre-calculated parameters are applied

    Stage migration is an accepted explanation for the association between lymph node (LN) yield and outcome in colon cancer. To investigate whether the alternative thesis of immune response is more likely, we performed a retrospective study. We enrolled 239 cases of node negative cancers, which were categorized according to the number of LNs with diameters larger than 5 mm (LN5) into the groups LN5-very low (0 to 1 LN5), LN5-low (2 to 5 LN5), and LN5-high (≥6 LN5). Significant differences were found in pT3/4 cancers with median survival times of 40, 57, and 71 months (P = .022) in the LN5-very low, LN5-low, and LN5-high groups, respectively. Multivariable analysis revealed that LN5 number and infiltration type were independent prognostic factors. LN size is prognostic in node negative colon cancer. The correct explanation for outcome differences associated with LN harvest is probably the activation status of LNs. Copyright © 2015 Elsevier Inc. All rights reserved.

    To determine if paraproteinemic keratopathy (PPK) in the setting of monoclonal gammopathy of undetermined significance (MGUS) causes distinct patterns of corneal opacification that can be distinguished from hereditary, immunologic, or inflammatory causes. A retrospective, interventional study of patients showed distinct bilateral opacity patterns of the cornea at the eye clinics of Hanau, Mainz, Helsinki, Marburg, and Berlin between 1993 and 2015. Data on patient characteristics and clinical features on ophthalmic examination were collected, and serum protein profiles were evaluated. A literature review and analysis of all published studies of MGUS with PPK is also presented. The largest group of patients diagnosed with MGUS-induced PPK is analyzed in this study. We studied 22 eyes of 11 patients (6 male, aged 43 to 65, mean age 54; 5 female, aged 49 to 76, mean age 61) with distinct corneal opacities and visual impairment who were first suspected of having hereditary, inflammatory, or immunologic corneal entities. Subsequently, serum protein electrophoresis revealed MGUS to be the cause of the PPK. Literature review revealed 72 patients with bilateral PPK (34 male, mean age 57; 38 female, mean age 58) in 51 studies of MGUS published from 1934 to 2015 and disclosed six additional corneal opacity patterns. This thesis shows that MGUS is not always an asymptomatic disorder, in contrast to the hematologic definition, which has no hint of PPK. The MGUS-induced PPK can mimic many other diseases of the anterior layer of the eye. A new clinical classification for PPK in MGUS is proposed.

    This paper discusses the practice of cost-benefit analyses of transportation infrastructure investment projects from the meta-theoretical perspective of critical realism. Such analyses are based on a number of untenable ontological assumptions about social value, human nature and the natural......-to-pay investigations. Accepting the ontological and epistemological assumptions of cost-benefit analysis involves an implicit acceptance of the ethical and political values favoured by these assumptions. Cost-benefit analyses of transportation investment projects tend to neglect long-term environmental consequences...

  14. Severity of complicated versus uncomplicated subthreshold depression: New evidence on the "Monotonicity Thesis" from the national comorbidity survey.

    Science.gov (United States)

    Wakefield, Jerome C; Schmitz, Mark F

    2017-04-01

    "Complicated" subthreshold depression (CsD) includes at least one of six pathosuggestive "complicated" symptoms: >6 months duration, marked role impairment, sense of worthlessness, suicidal ideation, psychotic ideation, and psychomotor retardation. "Uncomplicated" subthreshold depression (UsD) has no complicated features. Whereas studies show that complicated (CMDD) versus uncomplicated (UMDD) major depression differ substantially in severity and prognosis, UsD and CsD severity has not been previously compared. This study evaluates UsD and CsD pathology validator levels and examines whether the complicated/uncomplicated distinction offers incremental concurrent validity over the standard number-of-symptoms dimension as a depression severity measure. Using nationally representative community data from the National Comorbidity Survey, seven depression lifetime history subgroups were identified: one MDD screener symptom (n=1432); UsD (n=430); CsD (n=611); UMDD (n=182); and CMDD with 5-6 symptoms (n=518), 7 symptoms (n=217), and 8-9 symptoms (n=291). Severity was evaluated using five concurrent pathology validators: suicide attempt, interference with life, help seeking, hospitalization, and generalized anxiety disorder. CsD validator levels are substantially higher than both UsD and UMDD levels, and similar to mild CMDD, disconfirming the "monotonicity thesis" that severity increase with symptom number. Complicated/uncomplicated status predicts severity, and when complicatedness is controlled, number of symptoms no longer predicts validator levels. Diagnoses were based on respondents' fallible retrospective symptom reports during a lay-administered structured interview, which may not yield diagnoses comparable to clinicians' assessments. CsD is more severe than UsD and comparable to mild MDD. Complicated status more validly indicates depression severity than the standard number-of-symptoms measure. Copyright © 2017 Elsevier B.V.

    2001-01-01

    An analyse has been carried out in ST concerning the total costs for the division. Even though the target was the maintenance costs in ST, the global budget over has been analysed. This has been done since there is close relation between investments & consolidation and the required level for maintenance. The purpose of the analyse was to focus on maintenance cost in ST as a ratio of total maintenance costs over the replacement value of the equipment, and to make some comparisons with other industries and laboratories. Families of equipment have been defined and their corresponding ratios calculated. This first approach gives us some "quantitative" measurements. This analyse should be combined with performance indicators (more "qualitative" measurements) that are telling us how well we are performing. This will help us in defending our budget, make better priorities, and we will satisfy the requirements from our external auditors.

    Probabilistic risk analyses of nuclear power plants are carried out by systematically analyzing the possible consequences of a broad spectrum of causes of accidents. The risk can be expressed in the probabilities for melt down, radioactive releases, or harmful effects for the environment. Following risk policies for chemical installations as expressed in the mandatory nature of External Safety Reports (EVRs) or, e.g., the publication ''How to deal with risks'', probabilistic risk analyses are required for nuclear power plants

  2. Planning for Increased Bioenergy use - Strategies for Minimising Environmental Impacts and Analysing the Consequences

    International Nuclear Information System (INIS)

    Jonsson, Anna

    2006-08-01

    There are several goals aimed at increasing the use of renewable energy in the Swedish energy system. Bioenergy is one important renewable energy source and there is a potential to increase its use in the future. This thesis aimed to develop and analyse strategies and tools that could be used when planning for conversion to bioenergy-based heating systems and the building of new residential areas with bioenergy-based heating. The goal was to enable the increase of bioenergy and simultaneously minimise the negative health effects caused by emissions associated with the combustion of bioenergy. The thesis consists of two papers. Paper I concerned existing residential areas and conversion from electric heating and individual heating systems, such as firewood and oil boilers, to more modern and low-emitting pellet techniques and small-scale district heating. Paper II concerned new residential areas and how to integrate bioenergy-based heating systems that cause impacts on local air quality into the physical planning process through using Geographical Information Systems (GIS) and a meteorological dispersion model, ALARM. The results from Paper I indicated that it was possible to convert areas currently using electric heating to pellet techniques and small-scale district heating without degrading local air quality. Furthermore, it was possible to decrease high emissions caused by firewood boilers by replacing them with pellet boilers. The results from Paper II highlighted that GIS and ALARM were advantageous for analysing local air quality characteristics when planning for new residential areas and before a residential area is built: thus, avoiding negative impacts caused by bioenergy-based combustion. In conclusion, the work procedures developed in this thesis can be used to counteract negative impacts on local air quality with increasing use of bioenergy in the heating system.

  3. The Accuracy of Parameter Estimation in System Identification of Noisy Aircraft Load Measurement. Ph.D. Thesis

    Science.gov (United States)

    Kong, Jeffrey

    1994-01-01

    This thesis focuses on the subject of the accuracy of parameter estimation and system identification techniques. Motivated by a complicated load measurement from NASA Dryden Flight Research Center, advanced system identification techniques are needed. The objective of this problem is to accurately predict the load experienced by the aircraft wing structure during flight determined from a set of calibrated load and gage response relationship. We can then model the problem as a black box input-output system identification from which the system parameter has to be estimated. Traditional LS (Least Square) techniques and the issues of noisy data and model accuracy are addressed. A statistical bound reflecting the change in residual is derived in order to understand the effects of the perturbations on the data. Due to the intrinsic nature of the LS problem, LS solution faces the dilemma of the trade off between model accuracy and noise sensitivity. A method of conflicting performance indices is presented, thus allowing us to improve the noise sensitivity while at the same time configuring the degredation of the model accuracy. SVD techniques for data reduction are studied and the equivalence of the Correspondence Analysis (CA) and Total Least Squares Criteria are proved. We also looked at nonlinear LS problems with NASA F-111 data set as an example. Conventional methods are neither easily applicable nor suitable for the specific load problem since the exact model of the system is unknown. Neural Network (NN) does not require prior information on the model of the system. This robustness motivated us to apply the NN techniques on our load problem. Simulation results for the NN methods used in both the single load and the 'warning signal' problems are both useful and encouraging. The performance of the NN (for single load estimate) is better than the LS approach, whereas no conventional approach was tried for the 'warning signals' problems. The NN design methodology is also

    A mass separated neutral particle energy analyser which could simultaneously measure hydrogen and deuterium atoms emitted from tokamak plasma was constructed. The analyser was calibrated for the energy and mass separation in the energy range from 0.4 keV to 9 keV. In order to investigate the behavior of deuteron and proton in the JFT-2 tokamak plasma heated with ion cyclotron wave and neutral beam injection, this analyser was installed in JFT-2 tokamak. It was found that the energy spectrum could be determined with sufficient accuracy. The obtained ion temperature and ratio of deuteron and proton density from the energy spectrum were in good agreement with the value deduced from Doppler broadening of TiXIV line and the line intensities of H sub(α) and D sub(α) respectively.

    Hammonds, C.J.; Mayhall, J.A.

    1987-01-01

    The complex geometry of the Advance Toroidal Facility (ATF) vacuum vessel required special analysis techniques in investigating the structural behavior of the design. The response of a large-scale finite element model was found for transportation and operational loading. Several computer codes and systems, including the National Magnetic Fusion Energy Computer Center Cray machines, were implemented in accomplishing these analyses. The work combined complex methods that taxed the limits of both the codes and the computer systems involved. Using MSC/NASTRAN cyclic-symmetry solutions permitted using only 1/12 of the vessel geometry to mathematically analyze the entire vessel. This allowed the greater detail and accuracy demanded by the complex geometry of the vessel. Critical buckling-pressure analyses were performed with the same model. The development, results, and problems encountered in performing these analyses are described. 5 refs., 3 figs

    Some analyses of the heat conduction and elastic/inelastic stresses, carried out in Power Reactor and Nuclear Fuel Development Corporation (PNC) in fiscal 1973 using ANSYS (Engineering Analysis System) program, are summarized. In chapter I, the present state of structural analysis programs available for a FBR (fast breeder reactor) in PNC is explained. Chapter II is a brief description of the ANSYS current status. In chapter III are presented 8 examples of the steady-state and transient thermal analyses for fast-reactor plant components, and in chapter IV 5 examples of the inelastic structural analysis. With the advance in the field of finite element method, its applications in design study should extend progressively in the future. The present report, it is hoped, will contribute as references in similar analyses and at the same time help to understand the deformation and strain behaviors of structures. (Mori, K.)

    Gouffon, A; Zermizoglou, R

    1990-12-01

    The IAEA Safety Guide 50-SG-S8 devoted to 'Safety Aspects of Foundations of Nuclear Power Plants' indicates that operator of a NPP should establish a program for inspection of safe operation during construction, start-up and service life of the plant for obtaining data needed for estimating the life time of structures and components. At the same time the program should ensure that the safety margins are appropriate. Periodic safety analysis are an important part of the safety inspection program. Periodic safety reports is a method for testing the whole system or a part of the safety system following the precise criteria. Periodic safety analyses are not meant for qualification of the plant components. Separate analyses are devoted to: start-up, qualification of components and materials, and aging. All these analyses are described in this presentation. The last chapter describes the experience obtained for PWR-900 and PWR-1300 units from 1986-1989.

    A 30-channel time analyser is described. The time analyser was designed and built for pulsed neutron research but can be applied to other uses. Most of the logic is performed by means of ferrite memory core and transistor switching circuits. This leads to great versatility, low power consumption, extreme reliability and low cost. The analyser described provides channel Widths from 10 {mu}s to 10 ms; arbitrarily wider channels are easily obtainable. It can handle counting rates up to 2000 counts/min in each channel with less than 1% dead time loss. There is a provision for an initial delay equal to 100 channel widths. An input pulse de-randomizer unit using tunnel diodes ensures exactly equal channel widths. A brief description of the principles involved in core switching circuitry is given. The core-transistor transfer loop is compared with the usual core-diode loops and is shown to be more versatile and better adapted to the making of a time analyser. The circuits derived from the basic loop are described. These include the scale of ten, the frequency dividers and the delay generator. The current drivers developed for driving the cores are described. The crystal-controlled clock which controls the width of the time channels and synchronizes the operation of the various circuits is described. The detector pulse derandomizer unit using tunnel diodes is described. The scheme of the time analyser is then described showing how the various circuits can be integrated together to form a versatile time analyser. (author)

    A set of measurment control data analyses was selected for use by analysts responsible for maintaining measurement quality of nuclear materials accounting instrumentation. The analyses consist of control charts for bias and precision and statistical tests used as analytic supplements to the control charts. They provide the desired detection sensitivity and yet can be interpreted locally, quickly, and easily. The control charts provide for visual inspection of data and enable an alert reviewer to spot problems possibly before statistical tests detect them. The statistical tests are useful for automating the detection of departures from the controlled state or from the underlying assumptions (such as normality). 8 refs., 3 figs., 5 tabs

    This document is intended to provide a broad overview of the sources, characteristics, and analyses of natural and forced oscillatory behaviors in power systems. These aspects are necessarily linked. Oscillations appear in measurements with distinguishing characteristics derived from the oscillation’s source. These characteristics determine which analysis methods can be appropriately applied, and the results from these analyses can only be interpreted correctly with an understanding of the oscillation’s origin. To describe oscillations both at their source within a physical power system and within measurements, a perspective from the boundary between power system and signal processing theory has been adopted.

  12. Risk and reliability analyses (LURI) and expert judgement techniques

    International Nuclear Information System (INIS)

    Pyy, P.; Pulkkinen, U.

    1998-01-01

    Probabilistic safety analysis (PSA) is currently used as a regulatory licensing tool in risk informed and plant performance based regulation. More often also utility safety improvements are based on PSA calculations as one criterion. PSA attempts to comprehensively identify all important risk contributors, compare them with each other, assess the safety level and suggest improvements based on its findings. The strength of PSA is that it is capable to provide decision makers with numerical estimates of risks. This makes decision making easier than the comparison of purely qualitative results. PSA is the only comprehensive tool that compactly attempts to include all the important risk contributors in its scope. Despite the demonstrated strengths of PSA, there are some features that have reduced its uses. For example, the PSA scope has been limited to the power operation and process internal events (transients and LOCAs). Only lately, areas such as shutdown, external events and severe accidents have been included in PSA models in many countries. Problems related to modelling are, e.g., that rather static fault and event tree models are commonly used in PSA to model dynamic event sequences. Even if a valid model may be generated, there may not be any other data sources to be used than expert judgement. Furthermore, there are a variety of different techniques for human reliability assessment (HRA) giving varying results. In the project Reliability and Risk Analyses (LURI) these limitations and shortcomings have been studied. In the decision making area, case studies on the application of decision analysis and a doctoral thesis have been published. Further, practical aid has been given to utilities and regulatory decision making. Model uncertainty effect on PSA results has been demonstrated by two case studies. Human reliability has been studied both in the integrated safety analysis study and in the study of maintenance originated NPP component faults based on the

  13. Historical Consciousness in Youth. Theoretical and Exemplary Empirical Analyses

    Directory of Open Access Journals (Sweden)

    Carlos Kölbl

    2001-09-01

    Full Text Available The thesis that historical consciousness is an anthropological competence and category is called into question. A concept of modern historical consciousness is outlined which from then on serves as a working concept. This kind of historical consciousness, it is argued, is not a universal anthropological fact, but a result of the development of occidental cultures and societies. Long since a great number of groups and individuals have been deeply affected by this development in which the establishment of a scientific world view and methodical thinking played a major role. Their historical consciousness is modern since it refers to a radically temporalized and dynamic world and since it ties partial representations of this world to (implicit criteria of validity. Moreover it is closely connected with the possibility of self-critical reflections which are grounded in the historically mediated encounter with strangers. After a concise overview of the important questions and the state of the art in different disciplines, selected results of a broader qualitative-empirical study are presented. In the group discussions which were carried out with young people—only results from a discussion with thirteen to fourteen year old grammar-school pupils (Gymnasiasten are presented here—the analysis revealed clear indicators of a specifically modern historical consciousness. Looked at closely this consciousness is committed in a surprisingly high degree to scientific-methodical standards of rationality. One may welcome this as a successful implementation of a life form oriented towards rationality into young people's everyday life or deplore it as a symptom of the distortion of pragmatic orientations for activity and living by scientific standards: first of all it is a fact that the commitment to tie the reconstruction of past realities, historical events and contexts to an operation of knowledge which is intersubjectively transparent and rationally

    2014-06-01

    Full Text Available I den danske såvel som den internationale radiolitteratur er bud på metoder til analyse af radiomediet sparsomme. Det skyldes formentlig, at radiomediet er svært at analysere, fordi det er et medie, der ikke er visualiseret i form af billeder eller understøttet af printet tekst. Denne artikel har til formål at beskrive en ny kvantitativ metode til analyse af radio, der tager særligt hensyn til radiomediets modalitet – lyd struktureret som et lineært forløb i tid. Metoden understøtter dermed både radiomediet som et medie i tid og som et blindt medie. Metoden er udviklet i forbindelse med en komparativ analyse af kulturprogrammer på P1 og Radio24syv lavet for Danmarks Radio. Artiklen peger på, at metoden er velegnet til analyse af ikke kun radio, men også andre medieplatforme samt forskellige journalistiske stofområder.

  9. Reputation strength as a determinant of faculty employment: a test of the step-down thesis among clinical psychology doctoral programs.

    Science.gov (United States)

    Roberts, Michael C; Ilardi, Stephen S; Johnson, Rebecca J

    2006-07-01

    This study tested the folkloristic belief that doctoral degree recipients who pursue academic careers typically wind up at institutions ranked lower in prestige than the institutions at which they trained (the step-down thesis). We used a database of faculty members in 150 clinical psychology doctoral programs accredited by the American Psychological Association, and compared each faculty member's training institution with the current employing institution on three distinct reputation ranking systems: The Center (University of Florida, Gainesville) for overall university reputation, the National Research Council (Washington, DC) for doctoral degree department reputation, and the news magazine, U.S. News and World Report ranking for clinical psychology training program reputation. Although support for the step-down thesis was found across all three ranking systems, a disproportionately large number of professors were also observed to move laterally in terms of their employing institution's reputation.

  10. Grey literature in meta-analyses.

    Science.gov (United States)

    Conn, Vicki S; Valentine, Jeffrey C; Cooper, Harris M; Rantz, Marilyn J

    2003-01-01

    In meta-analysis, researchers combine the results of individual studies to arrive at cumulative conclusions. Meta-analysts sometimes include "grey literature" in their evidential base, which includes unpublished studies and studies published outside widely available journals. Because grey literature is a source of data that might not employ peer review, critics have questioned the validity of its data and the results of meta-analyses that include it. To examine evidence regarding whether grey literature should be included in meta-analyses and strategies to manage grey literature in quantitative synthesis. This article reviews evidence on whether the results of studies published in peer-reviewed journals are representative of results from broader samplings of research on a topic as a rationale for inclusion of grey literature. Strategies to enhance access to grey literature are addressed. The most consistent and robust difference between published and grey literature is that published research is more likely to contain results that are statistically significant. Effect size estimates of published research are about one-third larger than those of unpublished studies. Unfunded and small sample studies are less likely to be published. Yet, importantly, methodological rigor does not differ between published and grey literature. Meta-analyses that exclude grey literature likely (a) over-represent studies with statistically significant findings, (b) inflate effect size estimates, and (c) provide less precise effect size estimates than meta-analyses including grey literature. Meta-analyses should include grey literature to fully reflect the existing evidential base and should assess the impact of methodological variations through moderator analysis.

    This paper critiques the case for flexibilisation of labour markets. It evidences that influential claims for this in terms of an insider-outsider thesis by former Nobel economics committee member Assar Lindbeck and the British economist Dennis Snower were purely theoretical without offering any evidence, or recognising contrary evidence. It cites a recent admission by the IMF that there is no basis for claiming that protection of employee rights inhibits economic efficiency and cites also a ...

    Full Text Available Background: University based research is an integral part of many prestigious medical schools worldwide. The benefits of student-conducted research have long been highlighted in the literature. This article aims to identify the insights of medical students concerning research training, including perceived hurdles in the way of conducting research, and the utility of a research thesis in acquiring a Doctor of Medicine degree.Methods: A total of 808 medical students at Jordan University of Science and Technology were selected by random sampling with a confidence level of 95%. A survey was constructed by a group of students through literature review and group discussions. The survey utilized polar and Likert scale questions to collect data from the students. Statistical inferences were then obtained through analysis of means and one sample t-test of the hypothesis.Results: A total of 687 students filled out the survey (85%. Analysis shows that respondents have a strong and positive attitude towards research. The respondents with past research experience constituted 14.3% of those surveyed. Those respondents identified the barriers faced by them during their experience. The students showed high degree of agreement that a research thesis should be a prerequisite for graduation with statistical significance of p-value ≤0.05.Conclusion: Modifying the curriculum to include research methodology is recommended, and developing it to incorporate a thesis as a requirement for graduation may be advised upon further review.

    Energy Technology Data Exchange (ETDEWEB)

    1994-10-04

    Evaporator candidate feed from tank 241-AP-108 (108-AP) was sampled under prescribed protocol. Physical, inorganic, and radiochemical analyses were performed on tank 108-AP. Characterization of evaporator feed tank waste is needed primarily for an evaluation of its suitability to be safely processed through the evaporator. Such analyses should provide sufficient information regarding the waste composition to confidently determine whether constituent concentrations are within not only safe operating limits, but should also be relevant to functional limits for operation of the evaporator. Characterization of tank constituent concentrations should provide data which enable a prediction of where the types and amounts of environmentally hazardous waste are likely to occur in the evaporator product streams.

  2. Soil analyses by ICP-MS (Review)

    International Nuclear Information System (INIS)

    Yamasaki, Shin-ichi

    2000-01-01

    Soil analyses by inductively coupled plasma mass spectrometry (ICP-MS) are reviewed. The first half of the paper is devoted to the development of techniques applicable to soil analyses, where diverse analytical parameters are carefully evaluated. However, the choice of soil samples is somewhat arbitrary, and only a limited number of samples (mostly reference materials) are examined. In the second half, efforts are mostly concentrated on the introduction of reports, where a large number of samples and/or very precious samples have been analyzed. Although the analytical techniques used in these reports are not necessarily novel, valuable information concerning such topics as background levels of elements in soils, chemical forms of elements in soils and behavior of elements in soil ecosystems and the environment can be obtained. The major topics discussed are total elemental analysis, analysis of radionuclides with long half-lives, speciation, leaching techniques, and isotope ratio measurements. (author)

    1981-01-01

    Physical adsorption studies have been shown to be extremely valuable in studying the chemistry and structure of dispersed materials. Many processes rely on the access to the large amount of surface made available by the high degree of dispersion. Conversely, there are many applications where consolidation of the dispersed solids is required. Several systems (silica gel, alumina catalysts, mineralogic alumino-silicates, and yttrium oxide plasters) have been studied to show the type and amount of chemical and structural information that can be obtained. Some review of current theories is given and additional concepts are developed based on statistical and thermodynamic arguments. The results are applied to sorption data to show that detailed sorption analyses are extremely useful and can provide valuable information that is difficult to obtain by any other means. Considerable emphasis has been placed on data analyses and interpretation of a nonclassical nature to show the potential of such studies that is often not recognized nor utilized

    This paper describes improved capabilities for analyses of nuclear fuel shipping containers within SCALE -- a modular code system for Standardized Computer Analyses for Licensing Evaluation. Criticality analysis improvements include the new KENO V, a code which contains an enhanced geometry package and a new control module which uses KENO V and allows a criticality search on optimum pitch (maximum k-effective) to be performed. The SAS2 sequence is a new shielding analysis module which couples fuel burnup, source term generation, and radial cask shielding. The SAS5 shielding sequence allows a multidimensional Monte Carlo analysis of a shipping cask with code generated biasing of the particle histories. The thermal analysis sequence (HTAS1) provides an easy-to-use tool for evaluating a shipping cask response to the accident capability of the SCALE system to provide the cask designer or evaluator with a computational system that provides the automated procedures and easy-to-understand input that leads to standarization

    Die computergestützte bildbasierte Analyse der Herzfunktionen ist mittlerweile Standard in der Kardiologie. Die verfügbaren Produkte erfordern meist ein hohes Maß an Benutzerinteraktion und somit einen erhöhten Zeitaufwand. In dieser Arbeit wird ein Ansatz vorgestellt, der dem Kardiologen eine größtenteils automatische Analyse der Herzfunktionen mittels MRT-Bilddaten ermöglicht und damit Zeitersparnis schafft. Hierbei werden alle relevanten herzphysiologsichen Parameter berechnet und mithilfe von Diagrammen und Graphen visualisiert. Diese Berechnungen werden evaluiert, indem die ermittelten Werte mit manuell vermessenen verglichen werden. Der hierbei berechnete mittlere Fehler liegt mit 2,85 mm für die Wanddicke und 1,61 mm für die Wanddickenzunahme immer noch im Bereich einer Pixelgrösse der verwendeten Bilder.

    Kwak, H.-Y.; Kim, D.-J.; Jeon, J.-S.

    2003-01-01

    Exergetic and thermoeconomic analyses were performed for a 500-MW combined cycle plant. In these analyses, mass and energy conservation laws were applied to each component of the system. Quantitative balances of the exergy and exergetic cost for each component, and for the whole system was carefully considered. The exergoeconomic model, which represented the productive structure of the system considered, was used to visualize the cost formation process and the productive interaction between components. The computer program developed in this study can determine the production costs of power plants, such as gas- and steam-turbines plants and gas-turbine cogeneration plants. The program can be also be used to study plant characteristics, namely, thermodynamic performance and sensitivity to changes in process and/or component design variables

  8. Kinetic stability analyses in a bumpy cylinder

    International Nuclear Information System (INIS)

    Dominguez, R.R.; Berk, H.L.

    1981-01-01

    Recent interest in the ELMO Bumpy Torus (EBT) has prompted a number of stability analyses of both the hot electron rings and the toroidal plasma. Typically these works employ the local approximation, neglecting radial eigenmode structure and ballooning effects to perform the stability analysis. In the present work we develop a fully kinetic formalism for performing nonlocal stability analyses in a bumpy cylinder. We show that the Vlasov-Maxwell integral equations (with one ignorable coordinate) are self-adjoint and hence amenable to analysis using numerical techniques developed for self-adjoint systems of equations. The representation we obtain for the kernel of the Vlasov-Maxwell equations is a differential operator of arbitrarily high order. This form leads to a manifestly self-adjoint system of differential equations for long wavelength modes

    Cavitation instabilities have been predicted for a single void in a ductile metal stressed under high triaxiality conditions. In experiments for a ceramic reinforced by metal particles a single dominant void has been observed on the fracture surface of some of the metal particles bridging a crack......, and also tests for a thin ductile metal layer bonding two ceramic blocks have indicated rapid void growth. Analyses for these material configurations are discussed here. When the void radius is very small, a nonlocal plasticity model is needed to account for observed size-effects, and recent analyses......, while the surrounding voids are represented by a porous ductile material model in terms of a field quantity that specifies the variation of the void volume fraction in the surrounding metal....

  11. Analysing organic transistors based on interface approximation

    International Nuclear Information System (INIS)

    Akiyama, Yuto; Mori, Takehiko

    2014-01-01

    Temperature-dependent characteristics of organic transistors are analysed thoroughly using interface approximation. In contrast to amorphous silicon transistors, it is characteristic of organic transistors that the accumulation layer is concentrated on the first monolayer, and it is appropriate to consider interface charge rather than band bending. On the basis of this model, observed characteristics of hexamethylenetetrathiafulvalene (HMTTF) and dibenzotetrathiafulvalene (DBTTF) transistors with various surface treatments are analysed, and the trap distribution is extracted. In turn, starting from a simple exponential distribution, we can reproduce the temperature-dependent transistor characteristics as well as the gate voltage dependence of the activation energy, so we can investigate various aspects of organic transistors self-consistently under the interface approximation. Small deviation from such an ideal transistor operation is discussed assuming the presence of an energetically discrete trap level, which leads to a hump in the transfer characteristics. The contact resistance is estimated by measuring the transfer characteristics up to the linear region

  14. BWR core melt progression phenomena: Experimental analyses

    International Nuclear Information System (INIS)

    Ott, L.J.

    1992-01-01

    In the BWR Core Melt in Progression Phenomena Program, experimental results concerning severe fuel damage and core melt progression in BWR core geometry are used to evaluate existing models of the governing phenomena. These include control blade eutectic liquefaction and the subsequent relocation and attack on the channel box structure; oxidation heating and hydrogen generation; Zircaloy melting and relocation; and the continuing oxidation of zirconium with metallic blockage formation. Integral data have been obtained from the BWR DF-4 experiment in the ACRR and from BWR tests in the German CORA exreactor fuel-damage test facility. Additional integral data will be obtained from new CORA BWR test, the full-length FLHT-6 BWR test in the NRU test reactor, and the new program of exreactor experiments at Sandia National Laboratories (SNL) on metallic melt relocation and blockage formation. an essential part of this activity is interpretation and use of the results of the BWR tests. The Oak Ridge National Laboratory (ORNL) has developed experiment-specific models for analysis of the BWR experiments; to date, these models have permitted far more precise analyses of the conditions in these experiments than has previously been available. These analyses have provided a basis for more accurate interpretation of the phenomena that the experiments are intended to investigate. The results of posttest analyses of BWR experiments are discussed and significant findings from these analyses are explained. The ORNL control blade/canister models with materials interaction, relocation and blockage models are currently being implemented in SCDAP/RELAP5 as an optional structural component

    A mathematical model for fibrous structures using a direction dependent scaling law is presented. The orientation of fibrous nets (e.g. paper) is analysed with a method based on the curvelet transform. The curvelet-based orientation analysis has been tested successfully on real data from paper samples: the major directions of fibrefibre orientation can apparently be recovered. Similar results are achieved in tests on data simulated by the new model, allowing a comparison with ground truth

    In order to carry out the evaluation of safety status analyses by the safety assessor within the periodical safety reviews of nuclear power plants safety goal oriented requirements have been formulated together with complementary evaluation criteria. Their application in an inter-disciplinary coopertion covering the subject areas involved facilitates a complete safety goal oriented assessment of the plant status. The procedure is outlined briefly by an example for the safety goal 'reactivity control' for BWRs. (orig.) [de

  20. Application of RUNTA code in flood analyses

    Perez Martin, F.; Benitez Fonzalez, F.

    1994-01-01

    Flood probability analyses carried out to date indicate the need to evaluate a large number of flood scenarios. This necessity is due to a variety of reasons, the most important of which include: - Large number of potential flood sources - Wide variety of characteristics of flood sources - Large possibility of flood-affected areas becoming inter linked, depending on the location of the potential flood sources - Diversity of flood flows from one flood source, depending on the size of the rupture and mode of operation - Isolation times applicable - Uncertainties in respect of the structural resistance of doors, penetration seals and floors - Applicable degrees of obstruction of floor drainage system Consequently, a tool which carries out the large number of calculations usually required in flood analyses, with speed and flexibility, is considered necessary. The RUNTA Code enables the range of possible scenarios to be calculated numerically, in accordance with all those parameters which, as a result of previous flood analyses, it is necessary to take into account in order to cover all the possible floods associated with each flood area

  1. An analyser for power plant operations

    International Nuclear Information System (INIS)

    Rogers, A.E.; Wulff, W.

    1990-01-01

    Safe and reliable operation of power plants is essential. Power plant operators need a forecast of what the plant will do when its current state is disturbed. The in-line plant analyser provides precisely this information at relatively low cost. The plant analyser scheme uses a mathematical model of the dynamic behaviour of the plant to establish a numerical simulation. Over a period of time, the simulation is calibrated with measurements from the particular plant in which it is used. The analyser then provides a reference against which to evaluate the plant's current behaviour. It can be used to alert the operator to any atypical excursions or combinations of readings that indicate malfunction or off-normal conditions that, as the Three Mile Island event suggests, are not easily recognised by operators. In a look-ahead mode, it can forecast the behaviour resulting from an intended change in settings or operating conditions. Then, when such changes are made, the plant's behaviour can be tracked against the forecast in order to assure that the plant is behaving as expected. It can be used to investigate malfunctions that have occurred and test possible adjustments in operating procedures. Finally, it can be used to consider how far from the limits of performance the elements of the plant are operating. Then by adjusting settings, the required power can be generated with as little stress as possible on the equipment. (6 figures) (Author)

    Shaker, John F.

    1995-01-01

    In order to deploy large flexible space structures it is necessary to develop support systems that are strong and lightweight. The most recent example of this aerospace design need is vividly evident in the space station solar array assembly. In order to accommodate both weight limitations and strength performance criteria, ABLE Engineering has developed the Folding Articulating Square Truss (FASTMast) support structure. The FASTMast is a space truss/mechanism hybrid that can provide system support while adhering to stringent packaging demands. However, due to its slender nature and anticipated loading, stability characterization is a critical part of the design process. Furthermore, the dire consequences surely to result from a catastrophic instability quickly provide the motivation for careful examination of this problem. The fundamental components of the space station solar array system are the (1) solar array blanket system, (2) FASTMast support structure, and (3) mast canister assembly. The FASTMast once fully deployed from the canister will provide support to the solar array blankets. A unique feature of this structure is that the system responds linearly within a certain range of operating loads and nonlinearly when that range is exceeded. The source of nonlinear behavior in this case is due to a changing stiffness state resulting from an inability of diagonal members to resist applied loads. The principal objective of this study was to establish the failure modes involving instability of the FASTMast structure. Also of great interest during this effort was to establish a reliable analytical approach capable of effectively predicting critical values at which the mast becomes unstable. Due to the dual nature of structural response inherent to this problem, both linear and nonlinear analyses are required to characterize the mast in terms of stability. The approach employed herein is one that can be considered systematic in nature. The analysis begins with one

    1978-12-01

    Trace elements and their mobilization constitute an important consideration in the development of new fossil fuel technologies. Shale oil produced by in situ retorting of oil shale is an alternative fossil energy source. This study deals with the analysis of trace elements in various shale oil products using instrumental neutron activation analysis (INAA). INAA offers several advantages for those elements for which it is applicable. The greatest advantage is the lack of sample preparation prior to analysis, which greatly simplifies the process and prevents sample contamination. The elements for which analyses are reported in this study are aluminum, antimony, arsenic, bromine, cerium, chlorine, chromium, cobalt, copper, gallium, gold, iodine, iron, manganese, mercury, molybdenum, potassium, selenium, sodium, sulfur, tungsten, vanadium, and zinc

    The use of inelastic analysis methods instead of the traditional elastic analysis methods in the design of radioactive material (RAM) transport packagings leads to a better understanding of the response of the package to mechanical loadings. Thus, better assessment of the containment, thermal protection, and shielding integrity of the package after a structure accident event can be made. A more accurate prediction of the package response can lead to enhanced safety and also allow for a more efficient use of materials, possibly leading to a package with higher capacity or lower weight. This paper discusses the advantages and disadvantages of using inelastic analysis in the design of RAM shipping packages. The use of inelastic analysis presents several problems to the package designer. When using inelastic analysis the entire nonlinear response of the material must be known, including the effects of temperature changes and strain rate. Another problem is that there currently is not an acceptance criteria for this type of analysis that is approved by regulatory agencies. Inelastic analysis acceptance criteria based on failure stress, failure strain , or plastic energy density could be developed. For both elastic and inelastic analyses it is also important to include other sources of stress in the analyses, such as fabrication stresses, thermal stresses, stresses from bolt preloading, and contact stresses at material interfaces. Offsetting these added difficulties is the improved knowledge of the package behavior. This allows for incorporation of a more uniform margin of safety, which can result in weight savings and a higher level of confidence in the post-accident configuration of the package. In this paper, comparisons between elastic and inelastic analyses are made for a simple ring structure and for a package to transport a large quantity of RAM by rail (rail cask) with lead gamma shielding to illustrate the differences in the two analysis techniques

    The availability of complete genomic sequences for hundreds of organisms promises to make obtaining genome-wide estimates of substitution rates, selective constraints and other molecular evolution variables of interest an increasingly important approach to addressing broad evolutionary questions. Two of the programs most widely used for this purpose are codeml and baseml, parts of the PAML (Phylogenetic Analysis by Maximum Likelihood) suite. A significant drawback of these programs is their lack of a graphical user interface, which can limit their user base and considerably reduce their efficiency. We have developed IDEA (Interactive Display for Evolutionary Analyses), an intuitive graphical input and output interface which interacts with PHYLIP for phylogeny reconstruction and with codeml and baseml for molecular evolution analyses. IDEA's graphical input and visualization interfaces eliminate the need to edit and parse text input and output files, reducing the likelihood of errors and improving processing time. Further, its interactive output display gives the user immediate access to results. Finally, IDEA can process data in parallel on a local machine or computing grid, allowing genome-wide analyses to be completed quickly. IDEA provides a graphical user interface that allows the user to follow a codeml or baseml analysis from parameter input through to the exploration of results. Novel options streamline the analysis process, and post-analysis visualization of phylogenies, evolutionary rates and selective constraint along protein sequences simplifies the interpretation of results. The integration of these functions into a single tool eliminates the need for lengthy data handling and parsing, significantly expediting access to global patterns in the data.

    The safety evaluation of HTRs may be based on the three methods presented here: The licensing procedure, the probabilistic risk analysis, and the damage extent analysis. Thereby all safety aspects - from normal operation to the extreme (hypothetical) accidents - of the HTR are covered. The analyses within the licensing procedure of the HTR-1160 have shown that for normal operation and for the design basis accidents the radiation exposures remain clearly below the maximum permissible levels as prescribed by the radiation protection ordinance, so that no real hazard for the population will avise from them.

    Applications of a multi-layer neural network to numerical analyses are described. We are mainly concerned with the computed tomography and the solution of differential equations. In both cases as the objective functions for the training process of the neural network we employed residuals of the integral equation or the differential equations. This is different from the conventional neural network training where sum of the squared errors of the output values is adopted as the objective function. For model problems both the methods gave satisfactory results and the methods are considered promising for some kind of problems. (author)

    The phaco machine is frequently overlooked as the crucial surgical instrument it is. Understanding how to set parameters is initiated by understanding fundamental concepts of machine function. This study analyses the critical concepts of partial occlusion phaco, occlusion phaco and pump technology. In addition, phaco energy categories as well as variations of phaco energy production are explored. Contemporary power modulations and pump controls allow for the enhancement of partial occlusion phacoemulsification. These significant changes in the anterior chamber dynamics produce a balanced environment for phaco; less complications; and improved patient outcomes.

    The Olympus "Quickrate", a photometer built for both kinetic and end point analysis was evaluated in this laboratory. Aspartate transaminase, lactate dehydrogenase, hydroxybutyrate dehydrogenase, creatine kinase, alkaline phosphatase and gamma glutamyl transpeptidase were measured in the kinetic mode and glucose, urea, total protein, albumin, bilirubin, calcium and iron in the end point mode. Overall, good correlation was observed with routine methodologies and the precision of the methods was acceptable. An electrical evaluation was also performed. In our hands, the instrument proved to be simple to use and gave no trouble. It should prove useful for paediatric and emergency work, and as a back up for other analysers.

  18. Analyses of containment structures with corrosion damage

    Cherry, J.L.

    1997-01-01

    Corrosion damage that has been found in a number of nuclear power plant containment structures can degrade the pressure capacity of the vessel. This has prompted concerns regarding the capacity of corroded containments to withstand accident loadings. To address these concerns, finite element analyses have been performed for a typical PWR Ice Condenser containment structure. Using ABAQUS, the pressure capacity was calculated for a typical vessel with no corrosion damage. Multiple analyses were then performed with the location of the corrosion and the amount of corrosion varied in each analysis. Using a strain-based failure criterion, a open-quotes lower boundclose quotes, open-quotes best estimateclose quotes, and open-quotes upper boundclose quotes failure level was predicted for each case. These limits were established by: determining the amount of variability that exists in material properties of typical containments, estimating the amount of uncertainty associated with the level of modeling detail and modeling assumptions, and estimating the effect of corrosion on the material properties

  19. Analyser Framework to Verify Software Components

    Rolf Andreas Rasenack

    2009-01-01

    Full Text Available Today, it is important for software companies to build software systems in a short time-interval, to reduce costs and to have a good market position. Therefore well organized and systematic development approaches are required. Reusing software components, which are well tested, can be a good solution to develop software applications in effective manner. The reuse of software components is less expensive and less time consuming than a development from scratch. But it is dangerous to think that software components can be match together without any problems. Software components itself are well tested, of course, but even if they composed together problems occur. Most problems are based on interaction respectively communication. Avoiding such errors a framework has to be developed for analysing software components. That framework determines the compatibility of corresponding software components. The promising approach discussed here, presents a novel technique for analysing software components by applying an Abstract Syntax Language Tree (ASLT. A supportive environment will be designed that checks the compatibility of black-box software components. This article is concerned to the question how can be coupled software components verified by using an analyzer framework and determines the usage of the ASLT. Black-box Software Components and Abstract Syntax Language Tree are the basis for developing the proposed framework and are discussed here to provide the background knowledge. The practical implementation of this framework is discussed and shows the result by using a test environment.

    PAHKO project involved experiments on the PACTEL facility and computer simulations of selected experiments. The experiments focused on the performance of Passive Safety Injection Systems (PSIS) of Advanced Light Water Reactors (ALWRs) in Small Break Loss-Of-Coolant Accident (SBLOCA) conditions. The PSIS consisted of a Core Make-up Tank (CMT) and two pipelines (Pressure Balancing Line, PBL, and Injection Line, IL). The examined PSIS worked efficiently in SBLOCAs although the flow through the PSIS stopped temporarily if the break was very small and the hot water filled the CMT. The experiments demonstrated the importance of the flow distributor in the CMT to limit rapid condensation. The project included validation of three thermal-hydraulic computer codes (APROS, CATHARE and RELAP5). The analyses showed the codes are capable to simulate the overall behaviour of the transients. The detailed analyses of the results showed some models in the codes still need improvements. Especially, further development of models for thermal stratification, condensation and natural circulation flow with small driving forces would be necessary for accurate simulation of the PSIS phenomena.

    Preliminary system-level analyses of the interfaces between at-reactor used fuel management, consolidated storage facilities, and disposal facilities, along with the development of supporting logistics simulation tools, have been initiated to provide the U.S. Department of Energy (DOE) and other stakeholders with information regarding the various alternatives for managing used nuclear fuel (UNF) generated by the current fleet of light water reactors operating in the United States. An important UNF management system interface consideration is the need for ultimate disposal of UNF assemblies contained in waste packages that are sized to be compatible with different geologic media. Thermal analyses indicate that waste package sizes for the geologic media under consideration by the Used Fuel Disposition Campaign may be significantly smaller than the canisters being used for on-site dry storage by the nuclear utilities. Therefore, at some point along the UNF disposition pathway, there could be a need to repackage fuel assemblies already loaded and being loaded into the dry storage canisters currently in use. The implications of where and when the packaging or repackaging of commercial UNF will occur are key questions being addressed in this evaluation. The analysis demonstrated that thermal considerations will have a major impact on the operation of the system and that acceptance priority, rates, and facility start dates have significant system implications.

  2. Sensitivity in risk analyses with uncertain numbers.

    Energy Technology Data Exchange (ETDEWEB)

    Tucker, W. Troy; Ferson, Scott

    2006-06-01

    Sensitivity analysis is a study of how changes in the inputs to a model influence the results of the model. Many techniques have recently been proposed for use when the model is probabilistic. This report considers the related problem of sensitivity analysis when the model includes uncertain numbers that can involve both aleatory and epistemic uncertainty and the method of calculation is Dempster-Shafer evidence theory or probability bounds analysis. Some traditional methods for sensitivity analysis generalize directly for use with uncertain numbers, but, in some respects, sensitivity analysis for these analyses differs from traditional deterministic or probabilistic sensitivity analyses. A case study of a dike reliability assessment illustrates several methods of sensitivity analysis, including traditional probabilistic assessment, local derivatives, and a ''pinching'' strategy that hypothetically reduces the epistemic uncertainty or aleatory uncertainty, or both, in an input variable to estimate the reduction of uncertainty in the outputs. The prospects for applying the methods to black box models are also considered.

    2017-03-01

    Bipartite networks have attracted considerable interest in various fields. Fractality and multifractality of unipartite (classical) networks have been studied in recent years, but there is no work to study these properties of bipartite networks. In this paper, we try to unfold the self-similarity structure of bipartite networks by performing the fractal and multifractal analyses for a variety of real-world bipartite network data sets and models. First, we find the fractality in some bipartite networks, including the CiteULike, Netflix, MovieLens (ml-20m), Delicious data sets and (u, v)-flower model. Meanwhile, we observe the shifted power-law or exponential behavior in other several networks. We then focus on the multifractal properties of bipartite networks. Our results indicate that the multifractality exists in those bipartite networks possessing fractality. To capture the inherent attribute of bipartite network with two types different nodes, we give the different weights for the nodes of different classes, and show the existence of multifractality in these node-weighted bipartite networks. In addition, for the data sets with ratings, we modify the two existing algorithms for fractal and multifractal analyses of edge-weighted unipartite networks to study the self-similarity of the corresponding edge-weighted bipartite networks. The results show that our modified algorithms are feasible and can effectively uncover the self-similarity structure of these edge-weighted bipartite networks and their corresponding node-weighted versions.

    A scanning electron microscope (SEM) and an energy dispersive X-ray analyzer (EDAX) have been used to obtain information that clarifies the three mechanisms of coke formation in ethylene furnaces, and to analyze the metal condition at the exit of furnace. The results can be used to examine furnace operations and develop improved ethylene plant practices. In this first of four articles on the analyses of coke and metal samples, the coking mechanisms and coke deposits in a section of tube from an actual ethylene furnace (Furnace A) from a plant on the Texas Gulf Coast are discussed. The second articles in the series will analyze the condition of the tube metal in the same furnace. To show how coke deposition and metal condition dependent on the operating parameters of an ethylene furnace, the third article in the series will show the coke deposition in a Texas Gulf Coast furnace tube (Furnace B) that operated at shorter residence time. The fourth article discusses the metal condition in that furnace. Some recommendations, based on the analyses and findings, are offered in the fourth article that could help extend the life of ethylene furnace tubes, and also improve overall ethylene plant operations

    This paper presents an overview of an effort initiated in 1976 by the International Working Group on Fast Reactors (IWGFR) of the International Atomic Energy Agency (IAEA) to evaluate detailed and simplified inelastic analysis methods for piping systems with particular emphasis on piping bends. The procedure was to collect from participating member IAEA countries descriptions of tests and test results for piping systems or bends (with emphasis on high temperature inelastic tests), to compile, evaluate, and issue a selected number of these problems for analysis, and to compile and make a preliminary evaluation of the analyses results. Of the problem descriptions submitted three were selected to be used: a 90 0 -elbow at 600 0 C with an in-plane transverse force; a 90 0 -elbow with an in-plane moment; and a 180 0 -elbow at room temperature with a reversed, cyclic, in-plane transverse force. A variety of both detailed and simplified analysis solutions were obtained. A brief comparative assessment of the analyses is contained in this paper. 15 figures

  6. Ethics of cost analyses in medical education.

    Science.gov (United States)

    Walsh, Kieran

    2013-11-01

    Cost analyses in medical education are rarely straightforward, and rarely lead to clear-cut conclusions. Occasionally they do lead to clear conclusions but even when that happens, some stakeholders will ask difficult but valid questions about what to do following cost analyses-specifically about distributive justice in the allocation of resources. At present there are few or no debates about these issues and rationing decisions that are taken in medical education are largely made subconsciously. Distributive justice 'concerns the nature of a socially just allocation of goods in a society'. Inevitably there is a large degree of subjectivity in the judgment as to whether an allocation is seen as socially just or ethical. There are different principles by which we can view distributive justice and which therefore affect the prism of subjectivity through which we see certain problems. For example, we might say that distributive justice at a certain institution or in a certain medical education system operates according to the principle that resources must be divided equally amongst learners. Another system may say that resources should be distributed according to the needs of learners or even of patients. No ethical system or model is inherently right or wrong, they depend on the context in which the educator is working.

    Laramie E Duncan

    Full Text Available The quest to understand the neurobiology of schizophrenia and bipolar disorder is ongoing with multiple lines of evidence indicating abnormalities of glia, mitochondria, and glutamate in both disorders. Despite high heritability estimates of 81% for schizophrenia and 75% for bipolar disorder, compelling links between findings from neurobiological studies, and findings from large-scale genetic analyses, are only beginning to emerge.Ten publically available gene sets (pathways related to glia, mitochondria, and glutamate were tested for association to schizophrenia and bipolar disorder using MAGENTA as the primary analysis method. To determine the robustness of associations, secondary analyses were performed with: ALIGATOR, INRICH, and Set Screen. Data from the Psychiatric Genomics Consortium (PGC were used for all analyses. There were 1,068,286 SNP-level p-values for schizophrenia (9,394 cases/12,462 controls, and 2,088,878 SNP-level p-values for bipolar disorder (7,481 cases/9,250 controls.The Glia-Oligodendrocyte pathway was associated with schizophrenia, after correction for multiple tests, according to primary analysis (MAGENTA p = 0.0005, 75% requirement for individual gene significance and also achieved nominal levels of significance with INRICH (p = 0.0057 and ALIGATOR (p = 0.022. For bipolar disorder, Set Screen yielded nominally and method-wide significant associations to all three glial pathways, with strongest association to the Glia-Astrocyte pathway (p = 0.002.Consistent with findings of white matter abnormalities in schizophrenia by other methods of study, the Glia-Oligodendrocyte pathway was associated with schizophrenia in our genomic study. These findings suggest that the abnormalities of myelination observed in schizophrenia are at least in part due to inherited factors, contrasted with the alternative of purely environmental causes (e.g. medication effects or lifestyle.

    The dissolution of the Soviet Union resulted in sudden, widespread, and fundamental changes to Russian society. The former social welfare system-with its broad guarantees of employment, healthcare, education, and other forms of social support-was dismantled in the shift toward democracy, rule of law, and a free-market economy. This unique natural experiment provides a rare opportunity to examine the potentially disintegrative effects of rapid social change on deviance, and thus to evaluate one of Durkheim's core tenets. We took advantage of this opportunity by performing interrupted time-series analyses of annual age-adjusted homicide, suicide, and alcohol-related mortality rates for the Russian Federation using data from 1956 to 2002, with 1992-2002 as the postintervention time-frame. The ARIMA models indicate that, controlling for the long-term processes that generated these three time series, the breakup of the Soviet Union was associated with an appreciable increase in each of the cause-of-death rates. We interpret these findings as being consistent with the Durkheimian hypothesis that rapid social change disrupts social order, thereby increasing the level of crime and deviance.

    The DepUty (dependencies utility) can be classified as a project and process management tool. The main goal of DepUty is to assist by means of source code analysis and graphical representation using UML, in understanding dependencies of sub-systems and packages in CMS Object Oriented software, to understand architectural structure, and to schedule code release in modularised integration. It also allows a new-comer to more easily understand the global structure of CMS software, and to void circular dependencies up-front or re-factor the code, in case it was already too close to the edge of non-maintainability. The authors will discuss the various views DepUty provides to analyse package dependencies, and illustrate both the metrics and style checking facilities it provides

  13. Response surface use in safety analyses

    International Nuclear Information System (INIS)

    Prosek, A.

    1999-01-01

    When thousands of complex computer code runs related to nuclear safety are needed for statistical analysis, the response surface is used to replace the computer code. The main purpose of the study was to develop and demonstrate a tool called optimal statistical estimator (OSE) intended for response surface generation of complex and non-linear phenomena. The performance of optimal statistical estimator was tested by the results of 59 different RELAP5/MOD3.2 code calculations of the small-break loss-of-coolant accident in a two loop pressurized water reactor. The results showed that OSE adequately predicted the response surface for the peak cladding temperature. Some good characteristic of the OSE like monotonic function between two neighbor points and independence on the number of output parameters suggest that OSE can be used for response surface generation of any safety or system parameter in the thermal-hydraulic safety analyses.(author)

    Full Text Available The Harappan Civilization occupies a unique place among the early civilizations of the world with its well planned urban settlements, advanced handicraft and technology, religious and trade activities. Using a Geographical Information Systems (GIS, this study presents spatial analyses that locate urban settlements on a digital elevation model (DEM according to the three phases of early, mature and late. Understanding the relationship between the spatial distribution of Harappan sites and the change in some factors, such as topographic features, river passages or sea level changes, will lead to an understanding of the dynamism of this civilization. It will also afford a glimpse of the factors behind the formation, development, and decline of the Harappan Civilization.

  15. The plant design analyser and its applications

    1992-01-01

    Consideration is given to the history of computational methods for the non-linear dynamic analysis of plant behaviour. This is traced from analogue to hybrid computers. When these were phased out simulation languages were used in the batch mode and the interactive computational capabilities were lost. These have subsequently been recovered using mainframe computing architecture in the context of small models using the Prototype Plant Design Analyser. Given the development of parallel processing architectures, the restriction on model size can be lifted. This capability and the use of advanced Work Stations and graphics software has enabled an advanced interactive design environment to be developed. This system is generic and can be used, with suitable graphics development, to study the dynamics and control behaviour of any plant or system for minimum cost. Examples of past and possible future uses are identified. (author)

  16. Abundance analyses of thirty cool carbon stars

    International Nuclear Information System (INIS)

    Utsumi, Kazuhiko

    1985-01-01

    The results were previously obtained by use of the absolute gf-values and the cosmic abundance as a standard. These gf-values were found to contain large systematic errors, and as a result, the solar photospheric abundances were revised. Our previous results, therefore, must be revised by using new gf-values, and abundance analyses are extended for as many carbon stars as possible. In conclusion, in normal cool carbon stars heavy metals are overabundant by factors of 10 - 100 and rare-earth elements are overabundant by a factor of about 10, and in J-type cool carbon stars, C 12 /C 13 ratio is smaller, C 2 and CN bands and Li 6708 are stronger than in normal cool carbon stars, and the abundances of s-process elements with respect to Fe are nearly normal.

  17. Analysing Medieval Urban Space; a methodology

    Directory of Open Access Journals (Sweden)

    Marlous L. Craane MA

    2007-08-01

    Full Text Available This article has been written in reaction to recent developments in medieval history and archaeology, to study not only the buildings in a town but also the spaces that hold them together. It discusses a more objective and interdisciplinary approach for analysing urban morphology and use of space. It proposes a 'new' methodology by combining town plan analysis and space syntax. This methodology was trialled on the city of Utrecht in the Netherlands. By comparing the results of this 'new' methodology with the results of previous, more conventional, research, this article shows that space syntax can be applied successfully to medieval urban contexts. It does this by demonstrating a strong correlation between medieval economic spaces and the most integrated spaces, just as is found in the study of modern urban environments. It thus provides a strong basis for the use of this technique in future research of medieval urban environments.

  18. Reliability and safety analyses under fuzziness

    International Nuclear Information System (INIS)

    Onisawa, T.; Kacprzyk, J.

    1995-01-01

    Fuzzy theory, for example possibility theory, is compatible with probability theory. What is shown so far is that probability theory needs not be replaced by fuzzy theory, but rather that the former works much better in applications if it is combined with the latter. In fact, it is said that there are two essential uncertainties in the field of reliability and safety analyses: One is a probabilistic uncertainty which is more relevant for mechanical systems and the natural environment, and the other is fuzziness (imprecision) caused by the existence of human beings in systems. The classical probability theory alone is therefore not sufficient to deal with uncertainties in humanistic system. In such a context this collection of works will put a milestone in the arguments of probability theory and fuzzy theory. This volume covers fault analysis, life time analysis, reliability, quality control, safety analysis and risk analysis. (orig./DG). 106 figs

    We identify the chemical elements and element ratios that should be analyzed to address many of the issues identified by the Committee on Planetary and Lunar Exploration (COMPLEX). We determined that most of these issues require two sensitive instruments to analyze the necessary complement of elements. In addition, it is useful in many cases to use one instrument to analyze the outermost planetary surface (e.g. to determine weathering effects), while a second is used to analyze a subsurface volume of material (e.g., to determine the composition of unaltered planetary surface material). This dual approach to chemical analyses will also facilitate the calibration of orbital and/or Earth-based spectral observations of the planetary body. We determined that in many cases the scientific issues defined by COMPLEX can only be fully addressed with combined packages of instruments that would supplement the chemical data with mineralogic or visual information.

    2014-02-01

    Full Text Available Given the complexity of terrorism, solutions based on single factors are destined to fail. Systems thinking offers various tools for helping researchers and policy makers comprehend terrorism in its entirety. We have developed a semi-quantitative systems thinking approach for characterising relationships between variables critical to terrorism and their impact on the system as a whole. For a better understanding of the mechanisms underlying terrorism, we present a 16-variable model characterising the critical components of terrorism and perform a series of highly focused analyses. We show how to determine which variables are best suited for government intervention, describing in detail their effects on the key variable—the political influence of a terrorist network. We also offer insights into how to elicit variables that destabilise and ultimately break down these networks. Because we clarify our novel approach with fictional data, the primary importance of this paper lies in the new framework for reasoning that it provides.

    An economic-analysis summary was presented for the manufacture of crystalline-silicon modules involving silicon ingot/sheet, growth, slicing, cell manufacture, and module assembly. Economic analyses provided: useful quantitative aspects for complex decision-making to the Flat-plate Solar Array (FSA) Project; yardsticks for design and performance to industry; and demonstration of how to evaluate and understand the worth of research and development both to JPL and other government agencies and programs. It was concluded that future research and development funds for photovoltaics must be provided by the Federal Government because the solar industry today does not reap enough profits from its present-day sales of photovoltaic equipment.

  4. Level 2 probabilistic event analyses and quantification

    2003-01-01

    In this paper an example of quantification of a severe accident phenomenological event is given. The performed analysis for assessment of the probability that the debris released from the reactor vessel was in a coolable configuration in the lower drywell is presented. It is also analysed the assessment of the type of core/concrete attack that would occur. The coolability of the debris ex-vessel evaluation by an event in the Simplified Boiling Water Reactor (SBWR) Containment Event Tree (CET) and a detailed Decomposition Event Tree (DET) developed to aid in the quantification of this CET event are considered. The headings in the DET selected to represent plant physical states (e.g., reactor vessel pressure at the time of vessel failure) and the uncertainties associated with the occurrence of critical physical phenomena (e.g., debris configuration in the lower drywell) considered important to assessing whether the debris was coolable or not coolable ex-vessel are also discussed

    System models have recently been introduced to model organisations and evaluate their vulnerability to threats and especially insider threats. Especially for the latter these models are very suitable, since insiders can be assumed to have more knowledge about the attacked organisation than outside...... attackers. Therefore, many attacks are considerably easier to be performed for insiders than for outsiders. However, current models do not support explicit specification of different behaviours. Instead, behaviour is deeply embedded in the analyses supported by the models, meaning that it is a complex......, if not impossible task to change behaviours. Especially when considering social engineering or the human factor in general, the ability to use different kinds of behaviours is essential. In this work we present an approach to make the behaviour a separate component in system models, and explore how to integrate...

  6. ATLAS helicity analyses in beauty hadron decays

    2000-01-01

    The ATLAS detector will allow a precise spatial reconstruction of the kinematics of B hadron decays. In combination with the efficient lepton identification applied already at trigger level, ATLAS is expected to provide large samples of exclusive decay channels cleanly separable from background. These data sets will allow spin-dependent analyses leading to the determination of production and decay parameters, which are not accessible if the helicity amplitudes are not separated. Measurement feasibility studies for decays B/sub s //sup 0/ to J/ psi phi and Lambda /sub b//sup 0/ to Lambda J/ psi , presented in this document, show the experimental precisions that can be achieved in determination of B/sub s//sup 0/ and Lambda /sub b //sup 0/ characteristics.

    2013-01-01

    The objective of this paper is to analyze the stability of the rotational motion of a symmetrical spacecraft, in a circular orbit. The equilibrium points and regions of stability are established when components of the gravity gradient torque acting on the spacecraft are included in the equations of rotational motion, which are described by the Andoyer's variables. The nonlinear stability of the equilibrium points of the rotational motion is analysed here by the Kovalev-Savchenko theorem. With the application of the Kovalev-Savchenko theorem, it is possible to verify if they remain stable under the influence of the terms of higher order of the normal Hamiltonian. In this paper, numerical simulations are made for a small hypothetical artificial satellite. Several stable equilibrium points were determined and regions around these points have been established by variations in the orbital inclination and in the spacecraft principal moment of inertia. The present analysis can directly contribute in the maintenance of the spacecraft's attitude

  10. Cointegration Approach to Analysing Inflation in Croatia

    Lena Malešević-Perović

    2009-06-01

    Full Text Available The aim of this paper is to analyse the determinants of inflation in Croatia in the period 1994:6-2006:6. We use a cointegration approach and find that increases in wages positively influence inflation in the long-run. Furthermore, in the period from June 1994 onward, the depreciation of the currency also contributed to inflation. Money does not explain Croatian inflation. This irrelevance of the money supply is consistent with its endogeneity to exchange rate targeting, whereby the money supply is determined by developments in the foreign exchange market. The value of inflation in the previous period is also found to be significant, thus indicating some inflation inertia.

    We generated a comprehensive atlas of the immunologic cellular networks within human malignant pleural mesothelioma (MPM) using mass cytometry. Data-driven analyses of these high-resolution single-cell data identified 2 distinct immunologic subtypes of MPM with vastly different cellular composition, activation states, and immunologic function; mass spectrometry demonstrated differential abundance of MHC-I and -II neopeptides directly identified between these subtypes. The clinical relevance of this immunologic subtyping was investigated with a discriminatory molecular signature derived through comparison of the proteomes and transcriptomes of these 2 immunologic MPM subtypes. This molecular signature, representative of a favorable intratumoral cell network, was independently associated with improved survival in MPM and predicted response to immune checkpoint inhibitors in patients with MPM and melanoma. These data additionally suggest a potentially novel mechanism of response to checkpoint blockade: requirement for high measured abundance of neopeptides in the presence of high expression of MHC proteins specific for these neopeptides.

    2004-01-01

    Severe accidents in light water reactors involve complex physical phenomena. In the past there has been a heavy reliance on simple assumptions regarding physical phenomena alongside of probability methods to evaluate risks associated with severe accidents. Recently GE has developed realistic methodologies that permit deterministic evaluations of severe accident progression and of some of the associated phenomena in the case of Boiling Water Reactors (BWRs). These deterministic analyses indicate that with appropriate system modifications, and operator actions, core damage can be prevented in most cases. Furthermore, in cases where core-melt is postulated, containment failure can either be prevented or significantly delayed to allow sufficient time for recovery actions to mitigate severe accidents

    Directory of Open Access Journals (Sweden)

    Yannick Manche

    1999-06-01

    Full Text Available Le concept de risque repose sur deux notions :l'aléa, qui représente le phénomène physique par son amplitude et sa période retour ;la vulnérabilité, qui représente l'ensemble des biens et des personnes pouvant être touchés par un phénomène naturel.Le risque se définit alors comme le croisement de ces deux notions. Cette vision théorique permet de modéliser indépendamment les aléas et la vulnérabilité.Ce travail s'intéresse essentiellement à la prise en compte de la vulnérabilité dans la gestion des risques naturels. Son évaluation passe obligatoirement par une certaine analyse spatiale qui prend en compte l'occupation humaine et différentes échelles de l'utilisation de l'espace. Mais l'évaluation spatiale, que ce soit des biens et des personnes, ou des effets indirects se heurte à de nombreux problèmes. Il faut estimer l'importance de l'occupation de l'espace. Par ailleurs, le traitement des données implique des changements constants d'échelle pour passer des éléments ponctuels aux surfaces, ce que les systèmes d'information géographique ne gèrent pas parfaitement. La gestion des risques entraîne de fortes contraintes d'urbanisme, la prise en compte de la vulnérabilité permet de mieux comprendre et gérer les contraintes spatiales qu'impliquent les risques naturels. aléa, analyse spatiale, risques naturels, S.I.G., vulnérabilité

    2018-01-01

    The presence of matter in the path of relic photons causes distortions in the angular pattern of the cosmic microwave background (CMB) temperature fluctuations, modifying their properties in a slight but measurable way. Recently, the Planck Collaboration released the estimated convergence map, an integrated measure of the large-scale matter distribution that produced the weak gravitational lensing (WL) phenomenon observed in Planck CMB data. We perform exhaustive analyses of this convergence map calculating the variance in small and large regions of the sky, but excluding the area masked due to Galactic contaminations, and compare them with the features expected in the set of simulated convergence maps, also released by the Planck Collaboration. Our goal is to search for sky directions or regions where the WL imprints anomalous signatures to the variance estimator revealed through a χ2 analyses at a statistically significant level. In the local analysis of the Planck convergence map, we identified eight patches of the sky in disagreement, in more than 2σ, with what is observed in the average of the simulations. In contrast, in the large regions analysis we found no statistically significant discrepancies, but, interestingly, the regions with the highest χ2 values are surrounding the ecliptic poles. Thus, our results show a good agreement with the features expected by the Λ cold dark matter concordance model, as given by the simulations. Yet, the outliers regions found here could suggest that the data still contain residual contamination, like noise, due to over- or underestimation of systematic effects in the simulation data set.

    The ITER Vacuum Vessel has upper, equatorial, and lower ports used for equipment installation, diagnostics, heating and current drive systems, cryo-vacuum pumping, and access inside the vessel for maintenance. At the level of the divertor, the nine lower ports for remote handling, cryo-vacuum pumping and diagnostic are inclined downwards and toroidally located each every 40 o . The cryopump port has additionally a branch to allocate a second cryopump. The ports, as openings in the Vacuum Vessel, permit radiation streaming out of the vessel which affects the heating in the components in the outer regions of the machine inside and outside the ports. Safety concerns are also raised with respect to the dose after shutdown at the cryostat behind the ports: in such zones the radiation dose level must be kept below the regulatory limit to allow personnel access for maintenance purposes. Neutronic analyses have been required to qualify the ITER project related to the lower ports. A 3-D model was used to take into account full details of the ports and the lower machine surroundings. MCNP version 5 1.40 has been used with the FENDL 2.1 nuclear data library. The ITER 40 o model distributed by the ITER Organization was developed in the lower part to include the relevant details. The results of a first analysis, focused on cryopump system only, were recently published. In this paper more complete data on the cryopump port and analysis for the remote handling port and the diagnostic rack are presented; the results of both analyses give a complete map of the radiation loads in the outer divertor ports. Nuclear heating, dpa, tritium production, and dose rates after shutdown are provided and the implications for the design are discussed.

    To report the psychometrics of the Glaucoma Treatment Compliance Assessment Tool (GTCAT), a new questionnaire designed to assess adherence with glaucoma therapy. We developed the questionnaire according to the constructs of the Health Belief Model. We evaluated the questionnaire using data from a cross-sectional study with focus groups (n = 20) and a prospective observational case series (n=58). Principal components analysis provided assessment of construct validity. We repeated the questionnaire after 3 months for test-retest reliability. We evaluated predictive validity using an electronic dosing monitor as an objective measure of adherence. Focus group participants provided 931 statements related to adherence, of which 88.7% (826/931) could be categorized into the constructs of the Health Belief Model. Perceived barriers accounted for 31% (288/931) of statements, cues-to-action 14% (131/931), susceptibility 12% (116/931), benefits 12% (115/931), severity 10% (91/931), and self-efficacy 9% (85/931). The principal components analysis explained 77% of the variance with five components representing Health Belief Model constructs. Reliability analyses showed acceptable Cronbach's alphas (>.70) for four of the seven components (severity, susceptibility, barriers [eye drop administration], and barriers [discomfort]). Predictive validity was high, with several Health Belief Model questions significantly associated (P <.05) with adherence and a correlation coefficient (R (2)) of .40. Test-retest reliability was 90%. The GTCAT shows excellent repeatability, content, construct, and predictive validity for glaucoma adherence. A multisite trial is needed to determine whether the results can be generalized and whether the questionnaire accurately measures the effect of interventions to increase adherence.

    The Solar Dynamic Power Module being developed for Space Station Freedom uses a eutectic mixture of LiF-CaF2 phase change material (PCM) contained in toroidal canisters for thermal energy storage. Presented are the results from heat transfer analyses of a PCM containment canister. One and two dimensional finite difference computer models are developed to analyze heat transfer in the canister walls, PCM, void, and heat engine working fluid coolant. The modes of heat transfer considered include conduction in canister walls and solid PCM, conduction and pseudo-free convection in liquid PCM, conduction and radiation across PCM vapor filled void regions, and forced convection in the heat engine working fluid. Void shape, location, growth or shrinkage (due to density difference between the solid and liquid PCM phases) are prescribed based on engineering judgment. The PCM phase change process is analyzed using the enthalpy method. The discussion of the results focuses on how canister thermal performance is affected by free convection in the liquid PCM and void heat transfer. Characterizing these effects is important for interpreting the relationship between ground-based canister performance (in 1-g) and expected on-orbit performance (in micro-g). Void regions accentuate canister hot spots and temperature gradients due to their large thermal resistance. Free convection reduces the extent of PCM superheating and lowers canister temperatures during a portion of the PCM thermal charge period. Surprisingly small differences in canister thermal performance result from operation on the ground and operation on-orbit. This lack of a strong gravity dependency is attributed to the large contribution of container walls in overall canister energy redistribution by conduction.

    Terrestrial far ultraviolet (FUV) airglow emissions have been suggested as a means for remote sensing the structure of the upper atmosphere. The energy which leads to the excitation of FUV airglow emissions is solar irradiance at extreme ultraviolet (EUV) and soft x-ray wavelengths. Solar irradiance at these wavelengths is known to be highly variable; studies of nitric oxide (NO) in the lower thermosphere have suggested a variability of more than an order of magnitude in the solar soft x-ray irradiance. To properly interpret the FUV airflow, the magnitude of the solar energy deposition must be known. Previous analyses have used the electron impact excited Lyman-Birge-Hopfield (LBH) bands of N2 to infer the flux of photoelectrons in the atmosphere and thus to infer the magnitude of the solar irradiance. This dissertation presents the first simultaneous measurements of the FUV airglow, the major atmospheric constituent densities, and the solar EUV and soft x-ray irradiances. The measurements were made on three flights of an identical sounding rocket payload at different levels of solar activity. The linear response in brightness of the LBH bands to variations in solar irradiance is demonstrated. In addition to the N2 LBH bands, atomic oxygen lines at 135.6 and 130.4 nm are also studied. Unlike the LBH bands, these emissions undergo radiative transfer effects in the atmosphere. The OI emission at 135.6 nm is found to be well modeled using a radiative transfer calculation and the known excitation processes. Unfortunately, the assumed processes leading to OI 130.4 nm excitation are found to be insufficient to reproduce the observed variability of this emission. Production of NO in the atmosphere is examined; it is shown that a lower than previously reported variability in the solar soft x-ray irradiance is required to explain the variability of NO.

    Spectroscopy is one of the most powerful tools to study the physical properties and chemical composition of very diverse astrophysical environments. In principle, each nuclide has a unique set of spectral features; thus, establishing the presence of a specific material at astronomical distances requires no more than finding a laboratory spectrum of the right material that perfectly matches the astronomical observations. Once the presence of a substance is established, a careful analysis of the observational characteristics (wavelengths or frequencies, intensities, and line profiles) allows one to determine many physical parameters of the environment in which the substance resides, such as temperature, density, velocity, and so on. Because of this great diagnostic potential, ground-based and space-borne astronomical observatories often include instruments to carry out spectroscopic analyses of various celestial objects and events. Of particular interest is molecular spectroscopy at infrared wavelengths. From the spectroscopic point of view, molecules differ from atoms in their ability to vibrate and rotate, and quantum physics inevitably causes those motions to be quantized. The energies required to excite vibrations or rotations are such that vibrational transitions generally occur at infrared wavelengths, whereas pure rotational transitions typically occur at sub-mm wavelengths. Molecular vibration and rotation are coupled though, and thus at infrared wavelengths, one commonly observes a multitude of ro-vibrational transitions (see Figure 13.1). At lower spectral resolution, all transitions blend into one broad ro-vibrational molecular band. The isotope. Molecular spectroscopy thus allows us to see a difference of one neutron in an atomic nucleus that is located at astronomical distances! Since the detection of the first interstellar molecules (the CH [21] and CN [14] radicals), more than 150 species have been detected in space, ranging in size from diatomic

    André Feil (1884-1955) was a French physician best recognized for his description, coauthored with Maurice Klippel, of patients with congenital fusion of cervical vertebrae, a condition currently known as Klippel-Feil syndrome. However, little is known about his background aside from the fact that he was a student of Klippel and a physician who took a keen interest in describing congenital anomalies. Despite the relative lack of information on Feil, his contributions to the fields of spinal disease and teratology extended far beyond science to play an integral role in changing the misguided perception shrouding patients with disfigurements, defects, deformities, and so-called monstrous births. In particular, Feil's 1919 medical school thesis on cervical abnormalities was a critical publication in defying long-held theory and opinion that human "monstrosities," anomalies, developmental abnormalities, and altered congenital physicality were a consequence of sinful behavior or a reversion to a primitive state. Indeed, his thesis on a spinal deformity centering on his patient, L. Joseph, was at the vanguard for a new view of a patient as nothing less than fully human, no matter his or her physicality or appearance.
