  4. Arnold Hauser - a biography

    DEFF Research Database (Denmark)

    Larsen, Mihail

    It seems reasonable to regard Arnold Hauser's own biography in three different stories. First an official one, dealing with his public appearance through his publications. Another story has to be told about his personal life concentrating on his relationships with other intellectuals important...... to his biography. The last story deals with his self-estimation as an intellectual in a modern society....

  5. Albert Einstein a biography

    CERN Document Server

    Fölsing, Albrecht


    Albert Einstein's achievements are not just milestones in the history of science; decades ago they became an integral part of the twentieth-century world in which we live. Like no other modern physicist he altered and expanded our understanding of nature. Like few other scholars, he stood fully in the public eye. In a world changing with dramatic rapidity, he embodied the role of the scientist by personal example. Albrecht Folsing, relying on previously unknown sources and letters, brings Einstein's "genius" into focus. Whereas former biographies, written in the tradition of the history of science, seem to describe a heroic Einstein who fell to earth from heaven, Folsing attempts to reconstruct Einstein's thought in the context of the state of research at the turn of the century. Thus, perhaps for the first time, Einstein's surroundings come to light.

  7. «La Perfecta Casada»: from the Model to Representations. Francisca Zorrilla’s Biography, Written by her Husband

    Directory of Open Access Journals (Sweden)



    Full Text Available The existence of feminine models for Castilian women in the «postridentine» age is well known. Among these models, it stands out a work written by the Augustinian Fray Luis de León (1583. The great number of editions of the work proves its great success. «La Perfecta Casada» set a prototype of what a married woman should be and was read by many women. Decades after the appearance of this work, another was published in Alcalá (1661, which is not an ideal proposal but the story of a real life: the posthumous biography of Francisca Zorrilla written by her husband, Gabriel Álvarez de Velasco, judge at the «Chancillería» of Santa Fe. Her life, especially her married life, was exemplary. This work focuses on the biographical genre, on the author, on the story of life in its descriptive aspect, as well as on the adjustment to the archetype.

  8. Herman Melville, an Artist without a Biography

    Directory of Open Access Journals (Sweden)

    Mychailo Kalinichenko


    Full Text Available The article actualizes the necessity to specify methodological, historical and literary priorities, which may ensure the production of a biography of the creative work of Herman Melville, the author of the widely famous novel Moby-Dick. The urgency of the search for a principally new scholarly paradigm is conditioned by the crisis state of numerous North American biographies of the artist, which are primarily aimed at the exploration of documental materials. As the result of this scholarly devotion to obsolete positivistic, empirical models of thought, the existing variations of Melville's biography (including the authoritative two-volume biographical work of professor H. Parker leave unanswered the issues of creative character: the connections of the writer with the social and cultural reality of the United States of the first half of the nineteenth century remain unreciprocated; the problem of Melville's artistic evolution also awaits proper solutions. The author of the article realizes a textual comprehension of the writer's creativity and personal life. Biographical circumstances of the process of his artistic maturation are reviewed in terms of their connections with the discursive practices of Melville's age.

  10. Wu Chien-Shiung: A brief biography (United States)

    Chiang, Tsai-Chien


    My first encounter with professor Wu Chien-Shiung, a leading experimental physicist, 31 years ago inspired me to write her biography. I received much encouragement when planning this biography, especially from Dr. Yang Chen Ning, whose biography I wrote later. The real challenges in writing Wu's biography were finding the balance between both sides of her life and overcoming the obstacle that, unlike theoretical physicists (such as Yang), experimental physicists are inclined more to deeds than to words.

  11. Bookshelf. John Adams biography

    International Nuclear Information System (INIS)

    Billinge, Roy


    Full text: When John Bertram Adams died on 3 March 1984, CERN lost one of its principal architects. The late Sir John Adams was a very private person who rarely confided in his colleagues. This made the job of his biographer particularly difficult. Michael Crowley- Milling has succeeded admirably, and has performed a very important service. Is it a potted history of CERN, or the story of the building of the PS, or of the SPS? Yes, all of these, but most of all it is a thoughtful and discerning biography and a fitting tribute to a veritable giant of European science and technology. The sub-title,' Engineer Extraordinary' refers not only to John's outstanding ability as a builder of accelerators, but perhaps even more importantly, as a builder of teams and an 'engineer of opinions'. The book describes how John's attention to detail and intuitive engineering skills developed during the early part of his career, when working in radar research, and how he emerged as a natural leader in the building of the CERN PS. Then later, how his statesmanship enabled him to ''...rescue it (the 300 GeV Programme) from seeming political disaster and nurse it through technical problems to a successful conclusion.'' One crucial part of this process described is the visit to CERN in 1970 by Margaret Thatcher, at that time UK Secretary of State for Education and Science, and her subsequent letters of thanks, not only to Bernard Gregory as Director General, but also to John. It is interesting to speculate to what extent the good impression made on that occasion helped many years later, when as Prime Minister Mrs Thatcher decided that Britain should stay in CERN! After the successful commissioning of the SPS, the book goes on to describe the period when the two CERN Laboratories were merged under two Directors General. Unfortunately I found this part a little too low key, given that John and Leon van Hove presided over what was undoubtedly

  13. Ethnomusicological biography of the traditional folk musician: Biography of the gusle-player

    Directory of Open Access Journals (Sweden)

    Lajić-Mihajlović Danka


    Full Text Available With the development of ethnomusicology from a comparative discipline to an anthropologically oriented science there has been an increase in the significance of the biography of folk musicians as scientific sources. The intention of the anthropological thought to accept and theoretically consider human nature as open and dynamic, has been realized in the ethnomusicological plane through the understanding of music as a product of thinking and behaviour of a particular musician in given circumstances. The concept of an artist is especially complex in the field of oral music culture, where creation and performance are connected in one person and the transferring process involves direct communication. The attempt to overcome the dichotomy of the musicological and sociological, i. e. anthropological attitude in ethnomusicology by synthesizing concepts which involve music, culture and man has brought particular importance to the relations between individual biographies and 'biographies of the collective' - relevant historical ethnological, anthropological, sociological, culturological, religion ideological and other types of data. Observations enlightening the social side of the folk musician's personality make the necessary 'frame' for the biography: from 'objective' social circumstances which modelled it to the opinion of the cultural environment about his performing. The folk musician's biography oriented towards ethnomusicology involves the result of a critical evaluation of the picture based on the emic and ethic vision autobiographical data and the observations of others, primarily researchers. The complexity of a biographical discourse in ethnomusicology can be perfectly seen in the example of the gusle-player's biography, as a genre-determined solo role in the tradition. For studying the relation between a person and a style of music expression, concerning gusle-players it is important to bear in mind the change in the profile of gusle

  14. Gauß eine Biographie

    CERN Document Server

    Mania, Hubert


    Daniel Kehlmann hat ihn wiederentdeckt, den bedeutendsten Mathematiker der Neuzeit: Karl Friedrich Gauß (1777 1855). Seine überragenden wissenschaftlichen Leistungen waren schon seinen Zeitgenossen bewusst. Da Gauß jedoch nur einen Bruchteil seiner Entdeckungen veröffentlichte, erschloss sich erst der Nachwelt die Tiefgründigkeit und Reichweite seines Werks. Hubert Mania schildert in dieser ersten umfassenden Biographie die Geschichte eines genialen Wissenschaftlers und zugleich eine ganze Epoche. Gauß war ein Mann, der in einer Welt des Aufbruchs völlig zurückgezogen lebte. Dabei hat er wie kaum ein anderer unsere Sicht der Welt revolutioniert. Als Erster formulierte er eine nichteuklidische Geometrie und schuf damit die unentbehrliche Grundlage zu Einsteins Entwicklung der allgemeinen Relativitätstheorie. Eine glänzend geschriebene Biographie des weltberühmten und doch so unbekannten Genies Karl Friedrich Gauß.

  19. Researching Risk: Narrative, Biography, Subjectivity

    Directory of Open Access Journals (Sweden)

    Karen Henwood


    Full Text Available This article contributes to the development of methodological practices promoting greater epistemic reflexivity in risk research and in social science generally. Knowledge of the specific practices researchers will find useful cannot exist separately from any particular empirical project. Accordingly, we report on, and provide a reflective account of, the "nuclear risk" project that was part of the Social Contexts and Responses to Risk (SCARR network in the UK (2003-2008. A key focus is exploring the value of narrative methods—especially narrative elicitation methods—for understanding people's perceptions of, and ways of living with, risk. We credit our deployment of a narrative method with producing a rich form of data on risk-biography intersections, which have carried great significance in our analytical work on the way biographical experiences, dynamically unfolding through space and time, can be interrupted by risk events. Arguments from the literature on reflexive modernity are deployed to make the case for: researching risk in everyday life as a problematic in and of itself; placing concepts of risk-biography, risk-reflexivity and risk-subjectivity at centre stage; and finding ways to inquire into the social and psychic complexities involved in the dynamic construction and reconstruction of risk phenomena.

  6. Ethical issues in ageing and biography. (United States)

    Kenyon, G M


    The increasing use of biographical materials in research and intervention in the field of ageing gives rise to significant ethical issues. In this inquiry, four of these issues are explicated. First, the notion of informed consent is explored in relation to selected contexts of research and intervention in ageing and biography. Second, the issues of autonomy and competence are considered from the point of view of identifying contexts where biography is a prerequisite for ethically responsive action. The third ethical issue concerns respecting the groundrules of various biographical approaches. Finally, the notions of authenticity and truth in lifestories are explored in an attempt to clarify the limitations and expectations of ageing and biography. The discussion of these ethical issues proceeds on the basis of an argument that indicates the fundamental importance of biographical ageing or the stories we are.

  13. Marital Biography, Social Security Receipt, and Poverty. (United States)

    Lin, I-Fen; Brown, Susan L; Hammersmith, Anna M


    Increasingly, older adults are unmarried, which could mean a larger share is at risk of economic disadvantage. Using data from the 2010 Health and Retirement Study, we chart the diverse range of marital biographies, capturing marital sequences and timing, of adults who are age eligible for Social Security and examine three indicators of economic well-being: Social Security receipt, Social Security benefit levels, and poverty status. Partnereds are disproportionately likely to receive Social Security and they enjoy relatively high Social Security benefits and very low poverty levels. Among singles, economic well-being varies by marital biography and gender. Gray divorced and never-married women face considerable economic insecurity. Their Social Security benefits are relatively low, and their poverty rates are quite high (over 25%), indicating Social Security alone is not sufficient to prevent these women from falling into poverty. By comparison, gray widoweds are the most advantaged singles.

  14. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705). (United States)

    Moxham, Noah


    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  17. Telling Lives in Science: Essays on Scientific Biography

    International Nuclear Information System (INIS)

    Harman, Peter


    This collection of ten essays by historians of science, several of them biographers, is concerned with the role of scientific biography in forming conceptions of science and scientists. The essays include studies of the biographies of individual scientists, assessments of the aims and style of scientific portraits in different historical contexts, examinations of changing biographical interpretations of scientists, and much discussion of the methodological issues involved in the writing of scientific biographies. Many historians consider biography to be an ambiguous genre, its appeal based on nostalgia rather than history, with a focus on personality rather than historical context, but the biographer can reply that scientific biography reveals the practice of science at its most fundamental level. Indeed, scientific biography has provided a powerful medium in which public conceptions of science have been established. Einstein observed that 'the essential being of a man of my type lies in what he thinks and how he thinks', and his Autobiographical Notes suppress personality in favour of physics. But the biographer may see matters differently, and wish to integrate the public and the private life of the scientist. In their substantial introduction the editors discuss these and other problems, and the book is directed to the professional concerns of historians of science. While there is little here on the history of physics, Geoffrey Cantor's essay on public images of Faraday as constructed in popular biographies, a discussion of conflicting portraits of Faraday as romantic genius or hard-working slogger, may interest readers of this journal.

    Comparing the sources of a novel and a biography leads to the paradox that the freedom of fiction can allow a more “realistic” treatment of character than the restriction of biography to documented facts allows.

  19. A self-psychological approach to the study of biography: the interplay of narratives in psychoanalysis and biography. (United States)

    Hershberg, Sandra G


    This chapter is an exploration of the psychoanalytic aspects of biography and the biographical aspects of psychoanalysis. The narratives that emerge from biography and psychoanalytic treatment incorporate elements of empathy, ideology (theory), and transference/countertransference and are co-constructed within an intersubjective field involving the subjectivities of both participants, the biographer and her subject and the analyst and her analysand. I will provide examples that demonstrate the way in which these processes play out in the biographical realm. Correspondingly, I will illustrate the way in which the analyst's biography and analysand's autobiography change in the course of the psychoanalytic treatment. Salient differences between biographical and psychoanalytic endeavors are also discussed.

    Full Text Available With "life history of things" approach, devel-oped by archeologists and anthropologists, as museolo-gists and heritologists we can identify meaning trans-formations of the same thing, from its creating till today. This "biography" approach suggests thing’s unforeseea-ble semantic potential. So, museum object is not just evidence of certain past, but it potentially testifies about all its pasts, i.e. realities. This premise is recognized as a starting point for insight and analysis of different memory cultures and its transformations through the thing’s "life", and for developing a fusion between herit-age theory and museology, memory culture and bio-graphical approach to things. We can identify presences and absences in collective memory and its ever changing interrelation, organized or spontaneous, with personal memory and memory of other groups, like family. Thus, (former museum object is potential testimony of its museum sojourn, professional, social and political con-texts of acquisition, interpretation, presentation and, at last, putting away in boxes, or of its shifting to another institution. These premises are examined on example of entirety of former museum objects from, now closed, Museum of Illegal Partisan Printing Offices in Belgrade, Serbia

Einstein observed that 'the essential being of a man of my type lies in what he thinks and how he thinks', and his Autobiographical Notes suppress personality in favour of physics. But the biographer may see matters differently, and wish to integrate the public and the private life of the scientist. In their substantial introduction the editors discuss these and other problems, and the book is directed to the professional concerns of historians of science. While there is little here on the history of physics, Geoffrey Cantor's essay on public images of Faraday as constructed in popular biographies, a discussion of conflicting portraits of Faraday as romantic genius or hard-working slogger, may interest readers of this journal.

  6. A ''model'' geophysics program

    International Nuclear Information System (INIS)

    Nyquist, J.E.


    In 1993, I tested a radio-controlled airplane designed by Jim Walker of Brigham Young University for low-elevation aerial photography. Model-air photography retains most of the advantages of standard aerial photography --- the photographs can be used to detect lineaments, to map roads and buildings, and to construct stereo pairs to measure topography --- and it is far less expensive. Proven applications on the Oak Ridge Reservation include: updating older aerial records to document new construction; using repeated overflights of the same area to capture seasonal changes in vegetation and the effects of major storms; and detecting waste trench boundaries from the color and character of the overlying grass. Aerial photography is only one of many possible applications of radio-controlled aircraft. Currently, I am funded by the Department of Energy's Office of Technology Development to review the state of the art in microavionics, both military and civilian, to determine ways this emerging technology can be used for environmental site characterization. Being particularly interested in geophysical applications, I am also collaborating with electrical engineers at Oak Ridge National Laboratory to design a model plane that will carry a 3-component flux-gate magnetometer and a global positioning system, which I hope to test in the spring of 1994

  7. Whey protein stories - An experiment in writing a multidisciplinary biography. (United States)

    Jensen, Tenna; Bechshoeft, Rasmus L; Giacalone, Davide; Otto, Marie Haulund; Castro-Mejía, Josue; Bin Ahmad, Hajar Fauzan; Reitelseder, Søren; Jespersen, Astrid Pernille


    This is an experimental, dual-purpose article about whey protein and how to conduct interdisciplinary analyses and writings. On the one hand, this article is a multidisciplinary commodity biography, which consists of five descriptions of whey protein written by the five different research groups involved in the interdisciplinary research project CALM(Counteracting Age-related loss of Skeletal Muscle Mass). On the other hand, it is a meta-analysis, which aims to uncover and highlight examples of how the five descriptions contribute to each other with insights into the contextualisation of knowledge, contrasts between the descriptions and the new dimensions they bring to established fields of interest. The meta-analysis also contains a discussion of interdisciplinary study objects and the usefulness of the multidisciplinary commodity biography as a format for interdisciplinary publications. The article contributes to the field of food studies with a multidisciplinary biography of whey protein - including its sensory qualities and challenges, insights into its cultural history, its nutritional value and effects on the human body and an analysis of how it is perceived by people who consume it. The biography thereby expands upon existing understandings of whey protein while discussing the usefulness of employing the commodity biography format in interdisciplinary writing. Moreover, the article contributes to the field of interdisciplinary research by providing a practical example of a joint publication and reflections upon the existence, interaction and possibilities of monodisciplinary knowledge structures within interdisciplinary studies and publications.

  8. Model Checker for Java Programs (United States)

    Visser, Willem


    Java Pathfinder (JPF) is a verification and testing environment for Java that integrates model checking, program analysis, and testing. JPF consists of a custom-made Java Virtual Machine (JVM) that interprets bytecode, combined with a search interface to allow the complete behavior of a Java program to be analyzed, including interleavings of concurrent programs. JPF is implemented in Java, and its architecture is highly modular to support rapid prototyping of new features. JPF is an explicit-state model checker, because it enumerates all visited states and, therefore, suffers from the state-explosion problem inherent in analyzing large programs. It is suited to analyzing programs less than 10kLOC, but has been successfully applied to finding errors in concurrent programs up to 100kLOC. When an error is found, a trace from the initial state to the error is produced to guide the debugging. JPF works at the bytecode level, meaning that all of Java can be model-checked. By default, the software checks for all runtime errors (uncaught exceptions), assertions violations (supports Java s assert), and deadlocks. JPF uses garbage collection and symmetry reductions of the heap during model checking to reduce state-explosion, as well as dynamic partial order reductions to lower the number of interleavings analyzed. JPF is capable of symbolic execution of Java programs, including symbolic execution of complex data such as linked lists and trees. JPF is extensible as it allows for the creation of listeners that can subscribe to events during searches. The creation of dedicated code to be executed in place of regular classes is supported and allows users to easily handle native calls and to improve the efficiency of the analysis.

  10. Interactive differential equations modeling program

    International Nuclear Information System (INIS)

    Rust, B.W.; Mankin, J.B.


    Due to the recent emphasis on mathematical modeling, many ecologists are using mathematics and computers more than ever, and engineers, mathematicians and physical scientists are now included in ecological projects. However, the individual ecologist, with intuitive knowledge of the system, still requires the means to critically examine and adjust system models. An interactive program was developed with the primary goal of allowing an ecologist with minimal experience in either mathematics or computers to develop a system model. It has also been used successfully by systems ecologists, engineers, and mathematicians. This program was written in FORTRAN for the DEC PDP-10, a remote terminal system at Oak Ridge National Laboratory. However, with relatively minor modifications, it can be implemented on any remote terminal system with a FORTRAN IV compiler, or equivalent. This program may be used to simulate any phenomenon which can be described as a system of ordinary differential equations. The program allows the user to interactively change system parameters and/or initial conditions, to interactively select a set of variables to be plotted, and to model discontinuities in the state variables and/or their derivatives. One of the most useful features to the non-computer specialist is the ability to interactively address the system parameters by name and to interactively adjust their values between simulations. These and other features are described in greater detail

  13. (Anti-Biography and Neo-Impressionism

    Directory of Open Access Journals (Sweden)

    Foa, Michelle


    Full Text Available This article analyzes neo-impressionism in relation to the biographical model of art criticism and art history that became increasingly prevalent in France over the course of the 19th century. Examining the critical response to the neo-impressionists, as well as some of their pictures and writings, I argue for the centrality of questions of authorship, individuality, and subjectivity to the group and its reception. I identify a distinctly anti-biographical tendency in the movement, one that disquieted the critics and led them to try and re-inscribe biographical meaning back into the work of Georges Seurat. Indeed, though Seurat instituted a divide between his work and his life in a variety of ways, he also insisted throughout his career on his paternity over the neo-impressionist method. In all of these ways, the relationship between the self and art was a significant and problematic issue for the neo-impressionists and the critics around them.

  18. The olmec hatchet: biography and landscape

    International Nuclear Information System (INIS)

    Jaime R, O.


    All study of archaeological characterization parts of the macrostructure of the materials. For the above-mentioned, in our methodology it has preceded the physical description of this materials and their registration. Once inspected and studied the macrostructure of our corpus of information it is necessary to analyze it but it details using several techniques whose scale of work reaches the mineral proportions. To characterize the rock type we use the X-ray diffraction technique. The first problem that we had presented in our investigation was to know the rock type of most of our samples of axes. At macroscopic level we had received different assignments to the same rock: it was said that it was calcareous rock, shale, until it was suggested that it was a clay: caolinite. The diagnostic was made by different geologists. To leave the ambiguity I decided to carry out the analysis of X-ray diffraction. By this way we characterized our material. The problem had consisted of that the rocks had gone for a diagenetic process. When being per millennia under swamp conditions and sour floors, the rocks had lost temper in their external aspect, with what they looked like another type of rocks. The rocks are made up of minerals that in turn they are made up of atoms. The minerals are crystalline solids in the nature and it is possible to analyze them through the X rays. So that it can identify the crystalline organization of the minerals which are those that constitute a rock, it is necessary that the contained electrons in the atoms should be excited so that then they can liberate that energy and being able to read the pattern that they form. This study carries out by means of an electronic microscope of variable pressure Jeol model marks 5900 and another one carries out microanalysis for EDS by means of a detecting Oxford ISIS. This analysis gives us the existent elements in the sample. It was carried out the observation and taken of images of their topography, as well as

  8. Hesychios of Miletos and his Biography of Aristotle

    Directory of Open Access Journals (Sweden)

    Mikhail Egorochkin


    Full Text Available The paper consists of two parts. The first introductory part considers all the available testimonies about life and works of Hesychios of Miletos, the Byzantine historian and encyclopaedist of the 6th cent. A.D. The Introduction also contains a brief overview of the research literature on the issue. Some new assumptions are made about the dating and the purpose of the Roman and General History attributed to Hesychios. In particular, I suggest that the History was written in the early years of the reign of Justinian I and, perhaps, was intended for the upbringing and education of Hesychios’ son John. The second part of the paper contains a translation of the biography of Aristotle, which was attributed to Hesychios by V. Rose and which is believed to be a part of his Onomatologos or Table of Eminent Writers. The main value of this Biography is an extensive list of Aristotle’s writings. The translation is annotated and accompanied by an index of correspondences between the list of Hesychios and the two other extant lists of Aristotle’s works, belonging to Diogenes Laertius and Ptolemy-al-Garib.

  10. Using Biographies to Illustrate the Intrapersonal and Interpersonal Dynamics of Science (United States)

    Mori, Monica; Larson, Susan


    We describe using biographies in teaching a course about the intrapersonal and interpersonal dynamics of science, with an emphasis on the professional and personal experiences of women in science. In our course, Life of a Psychologist: Experiences of Women in Science, students examine biographies and scientific research written by female psychologists across the main research areas of psychology. Biographies by these female psychologists and research on the experiences of women scientists are used to highlight the intrapersonal and interpersonal dynamics of science. Intrapersonal dynamics refer to the changes that occur within a person, such as developing an identity as a scientist, having a voice, and achieving success. Interpersonal dynamics refer to exchanges between people, such as collaborating on research, mentorship, and balancing personal and professional lives. Qualitative data support using biographies in teaching about the dynamics of science. Suggestions for using biographies in other courses are provided. PMID:23493947

  11. Efficacy of ACA strategies in biography-driven science teaching: an investigation (United States)

    MacDonald, Grizelda L.; Miller, Stuart S.; Murry, Kevin; Herrera, Socorro; Spears, Jacqueline D.


    This study explored the biography-driven approach to teaching culturally and linguistically diverse students in science education. Biography-driven instruction (BDI) embraces student diversity by incorporating students' sociocultural, linguistic, cognitive, and academic dimensions of their biographies into the learning process (Herrera in Biography-driven culturally responsive teaching. Teachers College Press, New York, 2010). Strategies have been developed (Herrera, Kavimandan and Holmes in Crossing the vocabulary bridge: differentiated strategies for diverse secondary classrooms. Teachers College Press, New York, 2011) that provide teachers with instructional routines that facilitate BDI. Using systematic classroom observations we empirically demonstrate that these activate, connect, affirm, strategies are likely to be effective in increasing teachers' biography-driven practices. Implications for theory and practice are discussed.

  12. Model Checking JAVA Programs Using Java Pathfinder (United States)

    Havelund, Klaus; Pressburger, Thomas


    This paper describes a translator called JAVA PATHFINDER from JAVA to PROMELA, the "programming language" of the SPIN model checker. The purpose is to establish a framework for verification and debugging of JAVA programs based on model checking. This work should be seen in a broader attempt to make formal methods applicable "in the loop" of programming within NASA's areas such as space, aviation, and robotics. Our main goal is to create automated formal methods such that programmers themselves can apply these in their daily work (in the loop) without the need for specialists to manually reformulate a program into a different notation in order to analyze the program. This work is a continuation of an effort to formally verify, using SPIN, a multi-threaded operating system programmed in Lisp for the Deep-Space 1 spacecraft, and of previous work in applying existing model checkers and theorem provers to real applications.

  14. Language Teaching Models in Teacher Training Programs


    Aslan, Alper


    Any language teacher who has gone through some kind of training program for the teaching of English should be familiar with various specific language teaching models that constitute the core of the training process. A language teaching model is a guide that helps the trainee to sequence the activities designed for the expectations and needs of learners in a lesson. This paper reviews the common language teaching models in teacher training programs (PPP, OHE, III, TTT, TBLT, ESA, ARC) and disc...

  15. Biography and Action: A Schutzian Perspective to Life-world

    Directory of Open Access Journals (Sweden)

    Hermílio Santos


    Full Text Available Starting with the discussion on free-will and action, this paper discusses how Alfred Schutz approaches these issues for the comprehension of life-world. After a brief overview on how contemporary philosophers as Ernst Tugendhat and Ulrich Pothast face these problem, it is argued that for Schutz action plays a central role in his conception of life-world. The article goes further and advocates for the importance of exploring individual biographies as a way to provide an accurate understanding of actions. By the end of this text, it is suggested that the biographical narrative approach, as proposed by Fritz Schütze, as well as by Gabriele Rosenthal, is an important contribution to the Schutz’ perspective of the life-world and to adequately explore the most different social phenomena.

  19. Academic program models for undergraduate biomedical engineering. (United States)

    Krishnan, Shankar M


    There is a proliferation of medical devices across the globe for the diagnosis and therapy of diseases. Biomedical engineering (BME) plays a significant role in healthcare and advancing medical technologies thus creating a substantial demand for biomedical engineers at undergraduate and graduate levels. There has been a surge in undergraduate programs due to increasing demands from the biomedical industries to cover many of their segments from bench to bedside. With the requirement of multidisciplinary training within allottable duration, it is indeed a challenge to design a comprehensive standardized undergraduate BME program to suit the needs of educators across the globe. This paper's objective is to describe three major models of undergraduate BME programs and their curricular requirements, with relevant recommendations to be applicable in institutions of higher education located in varied resource settings. Model 1 is based on programs to be offered in large research-intensive universities with multiple focus areas. The focus areas depend on the institution's research expertise and training mission. Model 2 has basic segments similar to those of Model 1, but the focus areas are limited due to resource constraints. In this model, co-op/internship in hospitals or medical companies is included which prepares the graduates for the work place. In Model 3, students are trained to earn an Associate Degree in the initial two years and they are trained for two more years to be BME's or BME Technologists. This model is well suited for the resource-poor countries. All three models must be designed to meet applicable accreditation requirements. The challenges in designing undergraduate BME programs include manpower, facility and funding resource requirements and time constraints. Each academic institution has to carefully analyze its short term and long term requirements. In conclusion, three models for BME programs are described based on large universities, colleges, and

  20. Review of Margaret Mahler: A biography of the psychoanalyst. (United States)

    Bergner, Sharone


    Reviews the book, Margaret Mahler: A biography of the psychoanalyst by Alma Halbert Bond (see record 2008-07778-000). This psychobiography tells an evocative tale of the late Margaret Mahler's embattled, difficult, yet highly productive life. Mahler was a developmental researcher and a psychoanalyst. Her delineation of the separation-individuation process dramatically shifted psychoanalytic developmental theory, altering psychoanalytic understanding of pathogenesis and treatment. Her understanding of the mother-child matrix, as well as her approach to studying it, directly affected psychoanalytic child therapy as well, focusing clinical attention on the moment-by-moment vicissitudes of early development and also upon the possibility of altering its course through therapeutic intervention in the mother-child relationship. The book suffers from a number of problems: the narrative is sloppy, marred by numerous jarring, obvious, even surprising flaws. There is tremendous repetitiveness-sentences and whole passages are repeated verbatim within several pages. There are multiple errors, inconsistencies, and contradictions, including in the chapter notes and bibliography. Along with this shoddiness, there is reliance upon antiquated, sometimes simply inaccurate, conceptualizations and definitions of psychoanalytic and psychological ideas.

  1. Biografie fittizie di personaggi storici. (Auto)biografia, soggettività, teoria nel romanzo contemporaneo [Fictional Biographies of Historical Characters. (Auto)biography, Subjectivity, Theory in the Contemporary Novel


    Boldrini, Lucia


    Starting from the observation that both biography and the novel have been declared to be in a state of crisis in the twentieth century, this book studies how the phenomenon of fictional biographies of historical characters (novels that re-write the life of historical personages) exploits these two crises in order to rejuvenate both the novel and biography. "Biografie fittizie e personaggi storici" thus analyses the relationship that this fiction establishes with the theory and practice of bio...

  2. Logic integer programming models for signaling networks. (United States)

    Haus, Utz-Uwe; Niermann, Kathrin; Truemper, Klaus; Weismantel, Robert


    We propose a static and a dynamic approach to model biological signaling networks, and show how each can be used to answer relevant biological questions. For this, we use the two different mathematical tools of Propositional Logic and Integer Programming. The power of discrete mathematics for handling qualitative as well as quantitative data has so far not been exploited in molecular biology, which is mostly driven by experimental research, relying on first-order or statistical models. The arising logic statements and integer programs are analyzed and can be solved with standard software. For a restricted class of problems the logic models reduce to a polynomial-time solvable satisfiability algorithm. Additionally, a more dynamic model enables enumeration of possible time resolutions in poly-logarithmic time. Computational experiments are included.

  3. Description of mathematical models and computer programs

    International Nuclear Information System (INIS)


    The paper gives a description of mathematical models and computer programs for analysing possible strategies for spent fuel management, with emphasis on economic analysis. The computer programs developed, describe the material flows, facility construction schedules, capital investment schedules and operating costs for the facilities used in managing the spent fuel. The computer programs use a combination of simulation and optimization procedures for the economic analyses. Many of the fuel cycle steps (such as spent fuel discharges, storage at the reactor, and transport to the RFCC) are described in physical and economic terms through simulation modeling, while others (such as reprocessing plant size and commissioning schedules, interim storage facility commissioning schedules etc.) are subjected to economic optimization procedures to determine the approximate lowest-cost plans from among the available feasible alternatives

  4. Transcultural Experience and Multiple Biographies as a Research Topic

    Directory of Open Access Journals (Sweden)

    Maciej Falski


    Full Text Available Transcultural Experience and Multiple Biographies as a Research Topic Transculturality refers to the traditional understanding of culture as self-contained, concentrated around its own center and producing clear borders. “Trans” signifies the act of crossing; it signifies overcoming such borders. It looks at phenomena, people, and notions that are not limited to one communicational environment, but are represented in multiple locations, or contexts. Or rather—they cannot be fully ascribed to one “culture,” because they exhibit, traits of both (or more cultures. Culture studies often describe, also, people with “trans” life stories; it is not a matter of simple crossing of borders, living a bit in one environment and a bit in another. The point is that their sense of belonging is of a mixed, ambiguous character, and their identity is blurred. It is a question of practices that they draw from two or more sources, creating a peculiar amalgam characteristic of living “in between.” Transculturality, just like multiple biographies, means both partial belonging and dual belonging, which is very well illustrated by the case studies presented in the volume: they have in a way, varied roots, which means they bear unique, hybrid fruit.   Doświadczenie transkulturowe i biografie wielorakie jako temat badawczy Transkulturowość odnosi się do tradycyjnego pojmowania kultury jako samowystarczalnej, skoncentrowanej na sobie i wytwarzającej wyraźne granice. Przyrostek „trans” oznacza akt przekraczania tak wytyczonych granic. Kategoria transkulturowości skłania do patrzenia na zjawiska, biografie i pojęcia jako coś, co nie ogranicza się do jednego środowiska komunikacyjnego, lecz występuje bądź przejawia się w wielu miejscach i kontekstach. Można też powiedzieć, że nie można ich przypisać do jednej „kultury”, ponieważ reprezentują cechy dwóch (lub więcej wspólnot kulturowych. Studia kulturowe często zajmuj

    Directory of Open Access Journals (Sweden)

    A. E. Molchanov


    Full Text Available Algebraic program models with procedures are designed to analyze program semantic properties on their models called program schemes. Procedural liberisation problem and equivalence problem are stated for program models with procedures in which both defining parameters are chosen independently. Program models with procedures built over a given program model without procedures are investigated. Algorithms for both stated tasks are proposed for models where an additional restriction is applied: the intersection emptiness problem is solvable in the program model without procedures. Polynomial estimates for the complexity of the algorithms are shown. Some topics for further investigation are proposed.

    Karen H. Warren


    Full Text Available PDDP, the parallel data distribution preprocessor, is a data parallel programming model for distributed memory parallel computers. PDDP implements high-performance Fortran-compatible data distribution directives and parallelism expressed by the use of Fortran 90 array syntax, the FORALL statement, and the WHERE construct. Distributed data objects belong to a global name space; other data objects are treated as local and replicated on each processor. PDDP allows the user to program in a shared memory style and generates codes that are portable to a variety of parallel machines. For interprocessor communication, PDDP uses the fastest communication primitives on each platform.

  7. ZATPAC: a model consortium evaluates teen programs. (United States)

    Owen, Kathryn; Murphy, Dana; Parsons, Chris


    How do we advance the environmental literacy of young people, support the next generation of environmental stewards and increase the diversity of the leadership of zoos and aquariums? We believe it is through ongoing evaluation of zoo and aquarium teen programming and have founded a consortium to pursue those goals. The Zoo and Aquarium Teen Program Assessment Consortium (ZATPAC) is an initiative by six of the nation's leading zoos and aquariums to strengthen institutional evaluation capacity, model a collaborative approach toward assessing the impact of youth programs, and bring additional rigor to evaluation efforts within the field of informal science education. Since its beginning in 2004, ZATPAC has researched, developed, pilot-tested and implemented a pre-post program survey instrument designed to assess teens' knowledge of environmental issues, skills and abilities to take conservation actions, self-efficacy in environmental actions, and engagement in environmentally responsible behaviors. Findings from this survey indicate that teens who join zoo/aquarium programs are already actively engaged in many conservation behaviors. After participating in the programs, teens showed a statistically significant increase in their reported knowledge of conservation and environmental issues and their abilities to research, explain, and find resources to take action on conservation issues of personal concern. Teens also showed statistically significant increases pre-program to post-program for various conservation behaviors, including "I talk with my family and/or friends about things they can do to help the animals or the environment," "I save water...," "I save energy...," "When I am shopping I look for recycled products," and "I help with projects that restore wildlife habitat."

  9. Database structure for plasma modeling programs

    International Nuclear Information System (INIS)

    Dufresne, M.; Silvester, P.P.


    Continuum plasma models often use a finite element (FE) formulation. Another approach is simulation models based on particle-in-cell (PIC) formulation. The model equations generally include four nonlinear differential equations specifying the plasma parameters. In simulation a large number of equations must be integrated iteratively to determine the plasma evolution from an initial state. The complexity of the resulting programs is a combination of the physics involved and the numerical method used. The data structure requirements of plasma programs are stated by defining suitable abstract data types. These abstractions are then reduced to data structures and a group of associated algorithms. These are implemented in an object oriented language (C++) as object classes. Base classes encapsulate data management into a group of common functions such as input-output management, instance variable updating and selection of objects by Boolean operations on their instance variables. Operations are thereby isolated from specific element types and uniformity of treatment is guaranteed. Creation of the data structures and associated functions for a particular plasma model is reduced merely to defining the finite element matrices for each equation, or the equations of motion for PIC models. Changes in numerical method or equation alterations are readily accommodated through the mechanism of inheritance, without modification of the data management software. The central data type is an n-relation implemented as a tuple of variable internal structure. Any finite element program may be described in terms of five relational tables: nodes, boundary conditions, sources, material/particle descriptions, and elements. Equivalently, plasma simulation programs may be described using four relational tables: cells, boundary conditions, sources, and particle descriptions

  10. Transnational nursing programs: models, advantages and challenges. (United States)

    Wilson, Michael


    Conducting transnational programs can be a very rewarding activity for a School, Faculty or University. Apart from increasing the profile of the university, the conduct of transnational programs can also provide the university with openings for business opportunities, consultative activities, and collaborative research. It can also be a costly exercise placing an enormous strain on limited resources with little reward for the provider. Transnational ventures can become nonviable entities in a very short period of time due to unanticipated global economic trends. Transnational courses offered by Faculties of Business and Computing are commonplace, however, there is a growing number of health science programs, particularly nursing that are being offered transnational. This paper plans an overview of several models employed for the delivery of transnational nursing courses and discusses several key issues pertaining to conducting courses outside the host university's country.

  11. The NIAID Radiation Countermeasures Program business model. (United States)

    Hafer, Nathaniel; Maidment, Bert W; Hatchett, Richard J


    The National Institute of Allergy and Infectious Diseases (NIAID) Radiation/Nuclear Medical Countermeasures Development Program has developed an integrated approach to providing the resources and expertise required for the research, discovery, and development of radiation/nuclear medical countermeasures (MCMs). These resources and services lower the opportunity costs and reduce the barriers to entry for companies interested in working in this area and accelerate translational progress by providing goal-oriented stewardship of promising projects. In many ways, the radiation countermeasures program functions as a "virtual pharmaceutical firm," coordinating the early and mid-stage development of a wide array of radiation/nuclear MCMs. This commentary describes the radiation countermeasures program and discusses a novel business model that has facilitated product development partnerships between the federal government and academic investigators and biopharmaceutical companies.

  12. Stellar Atmospheric Modelling for the ACCESS Program (United States)

    Morris, Matthew; Kaiser, Mary Elizabeth; Bohlin, Ralph; Kurucz, Robert; ACCESS Team


    A goal of the ACCESS program (Absolute Color Calibration Experiment for Standard Stars) is to enable greater discrimination between theoretical astrophysical models and observations, where the comparison is limited by systematic errors associated with the relative flux calibration of the targets. To achieve these goals, ACCESS has been designed as a sub-orbital rocket borne payload and ground calibration program, to establish absolute flux calibration of stellar targets at high resolution spectra in addition to the HST/CALSPEC data, we have generated stellar atmosphere models for ACCESS flight candidates, as well as a selection of A and G stars from the CALSPEC database. Stellar atmosphere models were generated using Atlas 9 and Atlas 12 Kurucz stellar atmosphere software. The effective temperature, log(g), metallicity, and redenning were varied and the chi-squared statistic was minimized to obtain a best-fit model. A comparison of these models and the results from interpolation between grids of existing models will be presented. The impact of the flexibility of the Atlas 12 input parameters (e.g. solar metallicity fraction, abundances, microturbulent velocity) is being explored.

  15. Can Household Benefit from Stochastic Programming Models?

    DEFF Research Database (Denmark)

    Rasmussen, Kourosh Marjani; Madsen, Claus A.; Poulsen, Rolf


    The Danish mortgage market is large and sophisticated. However, most Danish mortgage banks advise private home-owners based on simple, if sensible, rules of thumb. In recent years a number of papers (from Nielsen and Poulsen in J Econ Dyn Control 28:1267–1289, 2004 over Rasmussen and Zenios in J...... Risk 10:1–18, 2007 to Pedersen et al. in Ann Oper Res, 2013) have suggested a model-based, stochastic programming approach to mortgage choice. This paper gives an empirical comparison of performance over the period 2000–2010 of the rules of thumb to the model-based strategies. While the rules of thumb...

  16. Genetic Programming for Automatic Hydrological Modelling (United States)

    Chadalawada, Jayashree; Babovic, Vladan


    One of the recent challenges for the hydrologic research community is the need for the development of coupled systems that involves the integration of hydrologic, atmospheric and socio-economic relationships. This poses a requirement for novel modelling frameworks that can accurately represent complex systems, given, the limited understanding of underlying processes, increasing volume of data and high levels of uncertainity. Each of the existing hydrological models vary in terms of conceptualization and process representation and is the best suited to capture the environmental dynamics of a particular hydrological system. Data driven approaches can be used in the integration of alternative process hypotheses in order to achieve a unified theory at catchment scale. The key steps in the implementation of integrated modelling framework that is influenced by prior understanding and data, include, choice of the technique for the induction of knowledge from data, identification of alternative structural hypotheses, definition of rules, constraints for meaningful, intelligent combination of model component hypotheses and definition of evaluation metrics. This study aims at defining a Genetic Programming based modelling framework that test different conceptual model constructs based on wide range of objective functions and evolves accurate and parsimonious models that capture dominant hydrological processes at catchment scale. In this paper, GP initializes the evolutionary process using the modelling decisions inspired from the Superflex framework [Fenicia et al., 2011] and automatically combines them into model structures that are scrutinized against observed data using statistical, hydrological and flow duration curve based performance metrics. The collaboration between data driven and physical, conceptual modelling paradigms improves the ability to model and manage hydrologic systems. Fenicia, F., D. Kavetski, and H. H.

  17. Time and death in compiled adab "biographies"

    Directory of Open Access Journals (Sweden)

    Kilpatrick, Hilary


    Full Text Available In mediaeval Arabic belles-lettres (adab, accounts of lives are usually made up of quite short reports akhbār. These akhbār. are arranged in different ways, one of which is chronological order, but the compilers of such accounts apparently accord relative insignificance to chronological order. This paper examines some "biographies" compiled by al-Ṣūlī and Abū 1-Faraj al-Iṣbahānī, showing that temporal progression can exist in a "biographical" presentation, either alone or more often combined with other ways of organising the material. It then focuses on the placing of subjects' deaths in life accounts and on how they are integrated with the rest of the material. In conclusion, I suggest that when temporal progression is absent in "biographical" presentations, this should be seen as reflecting a mediaeval Arabic approach to life writing which differs from modem expectations but has its own rationale.

    En el género árabe medieval del adab (bellas letras, los relatos de vidas están normalmente compuestos a base de pequeñas noticias (ajbār. Estos ajbār están organizados de distintas maneras, una de las cuales es el orden cronológico, aunque los compiladores de tales noticias dan aparentemente poca importancia a tal orden. Este artículo estudia algunas «biografías» recogidas por al-Ṣūlī y Abū 1-Faraŷ al-Iṣbahānī, y muestra que la progresión temporal puede existir en las presentaciones «biográficas», sola o junto con otras formas de organizar el material. En él se analiza también el lugar que las muertes de los personajes ocupan en el relato de sus vidas, y cómo se integran en el resto del material. En conclusión, propongo que si la progresión temporal está ausente en las presentaciones «biográficas», ello se debe a la manera característica que la literatura árabe medieval tiene de enfocar los relatos de vida, que posee su propia lógica, aunque difiera

    Richard Waller's ‘Life of Dr Robert Hooke’, prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting thi...

  20. Python Program to Select HII Region Models (United States)

    Miller, Clare; Lamarche, Cody; Vishwas, Amit; Stacey, Gordon J.


    HII regions are areas of singly ionized Hydrogen formed by the ionizing radiaiton of upper main sequence stars. The infrared fine-structure line emissions, particularly Oxygen, Nitrogen, and Neon, can give important information about HII regions including gas temperature and density, elemental abundances, and the effective temperature of the stars that form them. The processes involved in calculating this information from observational data are complex. Models, such as those provided in Rubin 1984 and those produced by Cloudy (Ferland et al, 2013) enable one to extract physical parameters from observational data. However, the multitude of search parameters can make sifting through models tedious. I digitized Rubin's models and wrote a Python program that is able to take observed line ratios and their uncertainties and find the Rubin or Cloudy model that best matches the observational data. By creating a Python script that is user friendly and able to quickly sort through models with a high level of accuracy, this work increases efficiency and reduces human error in matching HII region models to observational data.

  20. The lived experience of volunteering in a palliative care biography service. (United States)

    Beasley, Elizabeth; Brooker, Joanne; Warren, Narelle; Fletcher, Jane; Boyle, Christopher; Ventura, Adriana; Burney, Susan


    Many patients approaching death experience hopelessness, helplessness, and a depressed mood, and these factors can contribute to a difficult end-of-life (EoL) period. Biography services may assist patients in finding meaning and purpose at this time. The aim of our study was to investigate the lived experience of volunteers involved in a biography service in Melbourne, Australia, using a qualitative methodology. The participants were 10 volunteers who had participated in a biography service within a private palliative care service. Each volunteer was interviewed separately using a study-specific semistructured interview guide. The transcripts of these interviews were then subjected to thematic analysis. Analysis yielded the following themes: motivations for volunteering; dealing with death, dying, and existential issues; psychosocial benefits of volunteering; and benefits and challenges of working with patients and their families. Our results indicated that volunteering gave the volunteers a deeper appreciation of existential issues, and helped them to be more appreciative of their own lives and gain a deeper awareness of the struggles other people experience. They also suggested that volunteers felt that their involvement contributed to their own personal development, and was personally rewarding. Furthermore, the results highlighted that volunteers found that encounters with family members were sometimes challenging. While some were appreciative, others imposed time limits, became overly reliant on the volunteers, and were sometimes offended, hurt, and angered by what was included in the final biography. It is hoped that the findings of the current study will provide direction for improvements in the biography services that will benefit patients, family members, and volunteers. In particular, our findings highlight the need to provide ongoing support for volunteers to assist them in handling the challenges of volunteering in a palliative care setting.

In it in practice (with reference to the person of outstanding German scientist Karl Jaspers are considered the basic methods, applied during the process of preparation of the intellectual biography, the circle of research problem is defined, typical for the given direction and their specific character is explained. Special attention is given to interdisciplinary as the basic condition of a successful scientific work on the given direction of intellectual history. A number of problems is listed in the article with which the historian, making the intellectual biography, anyway faces. The necessity of overcoming highly specialized scientific frames during the preparation of the intellectual biography becomes abundantly clear as it is impossible to understand the historical determinates of foldings of the whole system of scientific outlook of the intellectual without the reference to the system analysis of its scientific views, without immersing to the sphere of his professional interests which, as is known, can be far from history. The specified fact is the main reason for criticism of the direction of intellectual history from the adherents of “pure” history. The author defines a circle of research problems, among which are: definition of a circle of the research problems, objectively rising before the historian-intellectualist, realization of the selection of methods of research, relevant to the solution of objectives, demonstration of a bright example of practical application of methods of interdisciplinary research within writing of the intellectual biography of Jaspers.

    The staff of the Nuclear Regulatory Commission is performing nuclear power plant design certification reviews based on a design process plan that describes the human factors engineering (HFE) program elements that are necessary and sufficient to develop an acceptable detailed design specification and an acceptable implemented design. There are two principal reasons for this approach. First, the initial design certification applications submitted for staff review did not include detailed design information. Second, since human performance literature and industry experiences have shown that many significant human factors issues arise early in the design process, review of the design process activities and results is important to the evaluation of an overall design. However, current regulations and guidance documents do not address the criteria for design process review. Therefore, the HFE Program Review Model (HFE PRM) was developed as a basis for performing design certification reviews that include design process evaluations as well as review of the final design. A central tenet of the HFE PRM is that the HFE aspects of the plant should be developed, designed, and evaluated on the basis of a structured top-down system analysis using accepted HFE principles. The HFE PRM consists of ten component elements. Each element in divided into four sections: Background, Objective, Applicant Submittals, and Review Criteria.

    Full Text Available Recent researches have shown that, everywhere in various sciences the systems are following stacked-based stored change behavior when subjected to events or varying environments “on and above” their normal situations. This paper presents a generalized data stack programming (GDSP model which is developed to describe the system changes under varying environment. These changes which are captured with different ways such as sensor reading are stored in matrices. Extraction algorithm and identification technique are proposed to extract the different layers between images and identify the stack class the object follows; respectively. The general multi-stacking network is presented including the interaction between various stack-based layering of some applications. The experiments prove that the concept of stack matrix gives average accuracy of 99.45%.

  7. Modeling Weather Impact on Ground Delay Programs (United States)

    Wang, Yao; Kulkarni, Deepak


    Scheduled arriving aircraft demand may exceed airport arrival capacity when there is abnormal weather at an airport. In such situations, Federal Aviation Administration (FAA) institutes ground-delay programs (GDP) to delay flights before they depart from their originating airports. Efficient GDP planning depends on the accuracy of prediction of airport capacity and demand in the presence of uncertainties in weather forecast. This paper presents a study of the impact of dynamic airport surface weather on GDPs. Using the National Traffic Management Log, effect of weather conditions on the characteristics of GDP events at selected busy airports is investigated. Two machine learning methods are used to generate models that map the airport operational conditions and weather information to issued GDP parameters and results of validation tests are described.

    Full Text Available In Switzerland, 39% of nursing home residents have a dementia related disease. Behavioral symptoms are increasingly observed as dementia progresses. These symptoms impair patients’ quality of life and are distressing to family caregivers and nurses. A person-centered approach, which includes the resident’s individual biography, reduces such symptoms. The most current literature describes how therapists include biographical information in designated therapies. However person-centered care takes place not only in specific activities. Nurses are responsible for their patients’ care 24 hours a day.

  12. A Component-based Programming Model for Composite, Distributed Applications (United States)

    Eidson, Thomas M.; Bushnell, Dennis M. (Technical Monitor)


    The nature of scientific programming is evolving to larger, composite applications that are composed of smaller element applications. These composite applications are more frequently being targeted for distributed, heterogeneous networks of computers. They are most likely programmed by a group of developers. Software component technology and computational frameworks are being proposed and developed to meet the programming requirements of these new applications. Historically, programming systems have had a hard time being accepted by the scientific programming community. In this paper, a programming model is outlined that attempts to organize the software component concepts and fundamental programming entities into programming abstractions that will be better understood by the application developers. The programming model is designed to support computational frameworks that manage many of the tedious programming details, but also that allow sufficient programmer control to design an accurate, high-performance application.

  14. Programming models for energy-aware systems (United States)

    Zhu, Haitao

    Energy efficiency is an important goal of modern computing, with direct impact on system operational cost, reliability, usability and environmental sustainability. This dissertation describes the design and implementation of two innovative programming languages for constructing energy-aware systems. First, it introduces ET, a strongly typed programming language to promote and facilitate energy-aware programming, with a novel type system design called Energy Types. Energy Types is built upon a key insight into today's energy-efficient systems and applications: despite the popular perception that energy and power can only be described in joules and watts, real-world energy management is often based on discrete phases and modes, which in turn can be reasoned about by type systems very effectively. A phase characterizes a distinct pattern of program workload, and a mode represents an energy state the program is expected to execute in. Energy Types is designed to reason about energy phases and energy modes, bringing programmers into the optimization of energy management. Second, the dissertation develops Eco, an energy-aware programming language centering around sustainability. A sustainable program built from Eco is able to adaptively adjusts its own behaviors to stay on a given energy budget, avoiding both deficit that would lead to battery drain or CPU overheating, and surplus that could have been used to improve the quality of the program output. Sustainability is viewed as a form of supply and demand matching, and a sustainable program consistently maintains the equilibrium between supply and demand. ET is implemented as a prototyped compiler for smartphone programming on Android, and Eco is implemented as a minimal extension to Java. Programming practices and benchmarking experiments in these two new languages showed that ET can lead to significant energy savings for Android Apps and Eco can efficiently promote battery awareness and temperature awareness in real

    Full Text Available This paper analyzes the interesting technique of adaptation of the film Becoming Jane, a biopic on the life of Jane Austen, released in 2007. Loosely based on Jon Spence's biography Becoming Jane Austen, the film faces the problem of the scarcity of information on Jane Austen's life through a technique that, if not original nor always satisfying, is nevertheless worth being studied. By recurring to the character descriptions and the anecdotes narrated in the novels, the film (and Spence's book too "fills in the blanks" in Austen's life by adding touches of romance with questionable historical accuracy and fictionalizes the writer's biography in order to adapt it to the stereotype of modern romantic film heroines.

  20. Tell me a story: MMPI responses and personal biography in the case of a serial killer. (United States)

    Nichols, David S


    The interpretation of MMPI (Hathaway & McKinley, 1943) profiles has emphasized a language of pathological attribution that often serves the interests of clinical description and actuarial prediction better than those of individual case formulation and an understanding of the adaptive forces involved in the production of symptomatic behavior. In this article, I illustrate a contrasting approach, one that emphasizes MMPI items and scales as instruments of personal biography, with the case of the serial murderer Jeffrey Dahmer.

    The life of George Price (1922-1975), the eccentric polymath genius and father of the Price equation, is used as a prism and counterpoint through which to consider an age-old evolutionary conundrum: the origins of altruism. This biographical project, and biography and history more generally, are considered in terms of the possibility of using form to convey content in particular ways. Closer to an art form than a science, this approach to scholarship presents both a unique challenge and promise.

  6. The many lives of Charles Darwin: early biographies and the definitive evolutionist. (United States)

    Lightman, Bernard


    This article focuses on the early book-length biographies of Darwin published from his death in 1882 up to 1900. By making 1900 the cutoff point I can examine the biographies produced when the iconic figure was not yet set in stone, and before the rediscovery of Mendel's work in the early twentieth century and the anniversary celebrations of 1909 changed the way in which Darwin was regarded. Darwin's biographers dealt with three major themes. First, several biographers emphasized his scientific abilities, in particular his powers of observation and his prowess in conducting experiments. Second, many biographers discussed his character, a key issue in determining whether or not he could be trusted as a scientific guide. Finally, his scientific theories and religious beliefs, and how they related to the evolutionary controversy, formed a topic taken up by most biographers. By focusing on these three themes, the biographies published before 1900 were important in shaping the image of Darwin that was forming in American and British culture.

  7. Troubadour Biographies and the Value of Authentic Love: Daude de Pradas and Uc de Saint Circ

    Directory of Open Access Journals (Sweden)

    Thomas Hinton


    Full Text Available The idea of an essential connection between the quality of a song and the sincerity of the emotion it expresses ("I sing because I love" is a topos used in various ways by troubadours, one which lent itself naturally to discussion of their relationship to audiences and to other poets. The topos transferred across to the thirteenth-century biographies (vidas found alongside the songs in numerous manuscripts, as in the arresting claim, made in the vida about Daude de Pradas, that his songs "did not spring from love and therefore did not find favour with audiences." Elsewhere, however, the biographies give a different account of inauthenticity, as the edge which allows troubadours to exercise control over their social environment; significantly, this version of the topos appears in the vida for Uc de Saint Circ, who is believed to be the main author of the corpus. In these contrasting accounts of poetic inauthenticity, we can see the biographies wrestling with questions of control and definition of the cultural capital of troubadour lyric: patron and poet, cleric and lay. The thirteenth century saw authors and their audiences increasingly asserting the lasting cultural value of vernacular literature in general, and (through its association with troubadour production Occitan in particular. Accordingly, these texts reflect the poets' engagement with the court audiences for whom they were writing, at the same time as they look ahead to the enduring record of posterity.

  9. Energy efficiency in nonprofit agencies: Creating effective program models

    Energy Technology Data Exchange (ETDEWEB)

    Brown, M.A.; Prindle, B.; Scherr, M.I.; White, D.L.


    Nonprofit agencies are a critical component of the health and human services system in the US. It has been clearly demonstrated by programs that offer energy efficiency services to nonprofits that, with minimal investment, they can educe their energy consumption by ten to thirty percent. This energy conservation potential motivated the Department of Energy and Oak Ridge National Laboratory to conceive a project to help states develop energy efficiency programs for nonprofits. The purpose of the project was two-fold: (1) to analyze existing programs to determine which design and delivery mechanisms are particularly effective, and (2) to create model programs for states to follow in tailoring their own plans for helping nonprofits with energy efficiency programs. Twelve existing programs were reviewed, and three model programs were devised and put into operation. The model programs provide various forms of financial assistance to nonprofits and serve as a source of information on energy efficiency as well. After examining the results from the model programs (which are still on-going) and from the existing programs, several replicability factors'' were developed for use in the implementation of programs by other states. These factors -- some concrete and practical, others more generalized -- serve as guidelines for states devising program based on their own particular needs and resources.

  10. Modeling, Specification and Construction of PLC-programs

    Directory of Open Access Journals (Sweden)

    E. V. Kuzmin


    Full Text Available A new approach to construction of reliable discrete PLC-programs with timers — programming based on specification and verification — is proposed. Timers are modelled in a discrete way. For the specification of a program behavior we use the linear-time temporal logic LTL. Programming is carried out in the ST-language according to a LTLspecification. A new approach to programming of PLC is shown by an example. The proposed programming approach provides an ability of a correctness analysis of PLC-programs using the model checking method. The programming requires fulfillment of the following two conditions: 1 a value of each variable should be changed not more than once per one full PLC-program implementation (per one full working cycle of PLC; 2 a value of each variable should only be changed in one place of a PLC-program. Under the proposed approach the change of the value of each program variable is described by a pair of LTL-formulas. The first LTL-formula describes situations that increase the value of the corresponding variable, the second LTL-formula specifies conditions leading to a decrease of the variable value. The LTL-formulas (used for specification of the corresponding variable behavior are constructive in the sense that they construct the PLC-program, which satisfies temporal properties expressed by these formulas. Thus, the programming of PLC is reduced to the construction of LTL-specification of the behavior of each program variable.

    This report describes the methodology for using a genetic programming model to develop tracking behaviors for autonomous, microscale robotic vehicles. The use of such vehicles for surveillance and detection operations has become increasingly important in defense and humanitarian applications. Through an evolutionary process similar to that found in nature, the genetic programming model generates a computer program that when downloaded onto a robotic vehicle's on-board computer will guide the robot to successfully accomplish its task. Simulations of multiple robots engaged in problem-solving tasks have demonstrated cooperative behaviors. This report also discusses the behavior model produced by genetic programming and presents some results achieved during the study

We use symbolic representation of algorithmic game semantics, where concrete values are replaced with symbolic ones. In this way, we can compactly...... represent program families with infinite integers as so-called (finite-state) featured symbolic automata. Specifically designed model checking algorithms are then employed to verify safety of all programs from a family at once and pinpoint those programs that are unsafe (respectively, safe).

    Cardoso, Jorge; Poels, Geert


    This SpringerBrief explores the internal workings of service systems. The authors propose a lightweight semantic model for an effective representation to capture the essence of service systems. Key topics include modeling frameworks, service descriptions and linked data, creating service instances, tool support, and applications in enterprises.Previous books on service system modeling and various streams of scientific developments used an external perspective to describe how systems can be integrated. This brief introduces the concept of white-box service system modeling as an approach to mo

    Full Text Available On the formation of Cioran’s vision of the world and man, influenced largely his belonging to precisely this and no other nation. Romanian fatalism, inability to illusions, seeing the inevitable, the Romanian people’s faith in the fact that sin and creation are the same and constant accusations against this creation are the constitutiveelements of Cioran’s thought. Carrying the baggage of experiences of the nation thrown out of history and time, Cioran, as a Romanian emigrant in France, found the best model for his own writing in rhetorical and satirical tradition of the French moralists of the seventeenth and eighteenth centuries, who were a combination of“lyrical sublimity and cynicism”, gentleness and hell. They showed him not only what is uncompromising in pursuing the motives of human action, looking at every thing from many different perspectives, or suspicion of any kind of doctrine, but they also became for him a model of style. Of all literary forms cultivated by moralists, Cioranappreciated most the fragment, that is to say a closed form, often paradoxical and witty that having nothing in common with the characteristic for large systems long strings of argument – that was a form of recording experience, and like this experience, assumed discontinuity. Being a spokesperson for the “philosophy of the onlymoments”, Cioran advocated not only against the system, but also against academic philosophy – grown with indifference, regardless of the state of mind, it seemed to him the result of reduction of vitality and a kind of escape into the impersonal world of unrest. State, which fully made Cioran realize the futility resorting to this kind of philosophy, was insomnia, from which the Romanian philosopher had suffered more or less since he was seventeen. According to the author of the Fall in the Time insomnia and boredom are the “minimum imbalance”, which we have to experience, when we want to get closer to some

  2. Consideration of an applied model of public health program infrastructure. (United States)

    Lavinghouze, René; Snyder, Kimberly; Rieker, Patricia; Ottoson, Judith


    Systemic infrastructure is key to public health achievements. Individual public health program infrastructure feeds into this larger system. Although program infrastructure is rarely defined, it needs to be operationalized for effective implementation and evaluation. The Ecological Model of Infrastructure (EMI) is one approach to defining program infrastructure. The EMI consists of 5 core (Leadership, Partnerships, State Plans, Engaged Data, and Managed Resources) and 2 supporting (Strategic Understanding and Tactical Action) elements that are enveloped in a program's context. We conducted a literature search across public health programs to determine support for the EMI. Four of the core elements were consistently addressed, and the other EMI elements were intermittently addressed. The EMI provides an initial and partial model for understanding program infrastructure, but additional work is needed to identify evidence-based indicators of infrastructure elements that can be used to measure success and link infrastructure to public health outcomes, capacity, and sustainability.

  3. Research on teacher education programs: logic model approach. (United States)

    Newton, Xiaoxia A; Poon, Rebecca C; Nunes, Nicole L; Stone, Elisa M


    Teacher education programs in the United States face increasing pressure to demonstrate their effectiveness through pupils' learning gains in classrooms where program graduates teach. The link between teacher candidates' learning in teacher education programs and pupils' learning in K-12 classrooms implicit in the policy discourse suggests a one-to-one correspondence. However, the logical steps leading from what teacher candidates have learned in their programs to what they are doing in classrooms that may contribute to their pupils' learning are anything but straightforward. In this paper, we argue that the logic model approach from scholarship on evaluation can enhance research on teacher education by making explicit the logical links between program processes and intended outcomes. We demonstrate the usefulness of the logic model approach through our own work on designing a longitudinal study that focuses on examining the process and impact of an undergraduate mathematics and science teacher education program.

  4. Soviet “Life Canon” in scientist’s biography and problem of its overcoming

    Directory of Open Access Journals (Sweden)

    Khazagerov Georgii Georgievich


    Full Text Available This article is dedicated to one of the fragments of modern textual culture, namely the presentation of the image of the scientist, usually presented in the book, devoted to anniversaries. Often it is the memories of students. Scientific pathos of the article is due to the fact that these memories do not always create a life image of the scientist, not realizing his appointment. Often different publications not only smooth personal traits of individuals, but also smooth individual features of the style of the authors and individual differences of their texts. The article identifies the causes of these phenomena. One of them is blind, non-functional copy of topos characteristic of Soviet biographies. It is, for example, a topos of poverty and democratic origin of the scientist who during the Soviet biographies was intended to carry out agitation and didactic function. Combining topos with biographical frame results in a maximum leveling in the representation of a person. Thus it appears what the article calls “Soviet life canon.” Another reason for the smoothing of individual style and create a speculative form of teaching is the penetration in the biographical genre of officialese expressing indifferent attitude to people. Concerning modern biographies of scientists officialese involves business style, that serves genres of reviews, i.e. all that is related to business decision-making relating to the work of the scientist. The article pointed out ways to overcome these negative trends in modern publications related to the demand for intimization category, which primarily should be shown in the plot structure of the narration.

    Andreyev, N I; Kurtyka, T; Oberli, L R; Perini, D; Russenschuck, Stephan; Siegel, N; Siemko, A; Tommasini, D; Vanenkov, I; Walckiers, L


    Superconducting single and twin aperture 1-m long dipole magnets are currently being fabricated at CERN at a rate of about one per month in the framework of the short dipole model program for the LHC. The program allows to study performance improvements coming from refinements in design, components and assembly options and to accumulate statistics based on a small-scale production. The experience thus gained provides in turn feedback into the long magnet program in industry. In recent models initial quenching fields above 9 T have been obtained and after a short training the conductor limit at 2 K is reached, resulting in a central bore field exceeding 10 T. The paper describes the features of recent single aperture models, the results obtained during cold tests and the plans to ensure the continuation of a vigorous model program providing input for the fabrication of the main LHC dipoles.

  12. Applying Model Checking to Industrial-Sized PLC Programs

    CERN Document Server

    AUTHOR|(CDS)2079190; Darvas, Daniel; Blanco Vinuela, Enrique; Tournier, Jean-Charles; Bliudze, Simon; Blech, Jan Olaf; Gonzalez Suarez, Victor M


    Programmable logic controllers (PLCs) are embedded computers widely used in industrial control systems. Ensuring that a PLC software complies with its specification is a challenging task. Formal verification has become a recommended practice to ensure the correctness of safety-critical software but is still underused in industry due to the complexity of building and managing formal models of real applications. In this paper, we propose a general methodology to perform automated model checking of complex properties expressed in temporal logics (\\eg CTL, LTL) on PLC programs. This methodology is based on an intermediate model (IM), meant to transform PLC programs written in various standard languages (ST, SFC, etc.) to different modeling languages of verification tools. We present the syntax and semantics of the IM and the transformation rules of the ST and SFC languages to the nuXmv model checker passing through the intermediate model. Finally, two real cases studies of \\CERN PLC programs, written mainly in th...

    Novotný, Jan


    The time in which we live is characterized by an ever-increasing amount of data that we are able to explore and acquire. In all fields of science we could find some examples. Processing large volumes of information thus brings the requirement for engaging computational science. With increasing demands on data processing is advantageous to use new technology and start using parallel computation. Effective use of current technology requires from programmers new knowledge and skills. They meet with the countless new programming models and tools. In this article, we summarize the most commonly used programming models and points which good programming model should meet. The article also try to highlight the reasons why one should use a structured parallel programming.

  20. SPSS and SAS programming for the testing of mediation models. (United States)

    Dudley, William N; Benuzillo, Jose G; Carrico, Mineh S


    Mediation modeling can explain the nature of the relation among three or more variables. In addition, it can be used to show how a variable mediates the relation between levels of intervention and outcome. The Sobel test, developed in 1990, provides a statistical method for determining the influence of a mediator on an intervention or outcome. Although interactive Web-based and stand-alone methods exist for computing the Sobel test, SPSS and SAS programs that automatically run the required regression analyses and computations increase the accessibility of mediation modeling to nursing researchers. To illustrate the utility of the Sobel test and to make this programming available to the Nursing Research audience in both SAS and SPSS. The history, logic, and technical aspects of mediation testing are introduced. The syntax files sobel.sps and, created to automate the computation of the regression analysis and test statistic, are available from the corresponding author. The reported programming allows the user to complete mediation testing with the user's own data in a single-step fashion. A technical manual included with the programming provides instruction on program use and interpretation of the output. Mediation modeling is a useful tool for describing the relation between three or more variables. Programming and manuals for using this model are made available.

  1. Report of the 2014 Programming Models and Environments Summit

    Energy Technology Data Exchange (ETDEWEB)

    Heroux, Michael [US Dept. of Energy, Washington, DC (United States); Lethin, Richard [US Dept. of Energy, Washington, DC (United States)


    Programming models and environments play the essential roles in high performance computing of enabling the conception, design, implementation and execution of science and engineering application codes. Programmer productivity is strongly influenced by the effectiveness of our programming models and environments, as is software sustainability since our codes have lifespans measured in decades, so the advent of new computing architectures, increased concurrency, concerns for resilience, and the increasing demands for high-fidelity, multi-physics, multi-scale and data-intensive computations mean that we have new challenges to address as part of our fundamental R&D requirements. Fortunately, we also have new tools and environments that make design, prototyping and delivery of new programming models easier than ever. The combination of new and challenging requirements and new, powerful toolsets enables significant synergies for the next generation of programming models and environments R&D. This report presents the topics discussed and results from the 2014 DOE Office of Science Advanced Scientific Computing Research (ASCR) Programming Models & Environments Summit, and subsequent discussions among the summit participants and contributors to topics in this report.

  2. Modelling the work flow of a nuclear waste management program

    International Nuclear Information System (INIS)

    Hoeyer Mortensen, K.; Pinci, V.


    In this paper we describe a modelling project to improve a nuclear waste management program in charge of the creation of a new system for the permanent disposal of nuclear waste. SADT (Structural Analysis and Design Technique) is used in order to provide a work-flow description of the functions to be performed by the waste management program. This description is then translated into a number of Coloured Petri Nets (CPN or CP-nets) corresponding to different program functions where additional behavioural inscriptions provide basis for simulation. Each of these CP-nets is simulated to produce timed event charts that are useful for understanding the behaviour of the program functions under different scenarios. Then all the CPN models are linked together to form a single stand-alone application that is useful for validating the interaction and cooperation between the different program functions. A technique for linking executable CPN models is developed for supporting large modelling projects and parallel development of independent CPN models. (au) 11 refs

  3. Modeling and prioritizing demand response programs in power markets

    International Nuclear Information System (INIS)

    Aalami, H.A.; Moghaddam, M. Parsa; Yousefi, G.R.


    One of the responsibilities of power market regulator is setting rules for selecting and prioritizing demand response (DR) programs. There are many different alternatives of DR programs for improving load profile characteristics and achieving customers' satisfaction. Regulator should find the optimal solution which reflects the perspectives of each DR stakeholder. Multi Attribute Decision Making (MADM) is a proper method for handling such optimization problems. In this paper, an extended responsive load economic model is developed. The model is based on price elasticity and customer benefit function. Prioritizing of DR programs can be realized by means of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Considerations of ISO/utility/customer regarding the weighting of attributes are encountered by entropy method. An Analytical Hierarchy Process (AHP) is used for selecting the most effective DR program. Numerical studies are conducted on the load curve of the Iranian power grid in 2007. (author)

    Abdelwahed, Mohamed F.


    One of the seismological programs to manipulate seismic data is SGRAPH program. It consists of integrated tools to perform advanced seismological techniques. SGRAPH is considered a new system for maintaining and analyze seismic waveform data in a stand-alone Windows-based application that manipulate a wide range of data formats. SGRAPH was described in detail in the first part of this paper. In this part, I discuss the advanced techniques including in the program and its applications in seismology. Because of the numerous tools included in the program, only SGRAPH is sufficient to perform the basic waveform analysis and to solve advanced seismological problems. In the first part of this paper, the application of the source parameters estimation and hypocentral location was given. Here, I discuss SGRAPH waveform modeling tools. This paper exhibits examples of how to apply the SGRAPH tools to perform waveform modeling for estimating the focal mechanism and crustal structure of local earthquakes.

  6. Results of a Formal Mentorship Program for Internal Medicine Residents: Can We Facilitate Genuine Mentorship? (United States)

    Cohee, Brian M; Koplin, Stephen A; Shimeall, William T; Quast, Timothy M; Hartzell, Joshua D


    Mentorship programs are perceived as valuable, yet little is known about the effect of program design on mentoring effectiveness. We developed a program focused on mentoring relationship quality and evaluated how subsequent relationships compared to preexisting informal pairings. Faculty members were invited by e-mail to participate in a new mentoring program. Participants were asked to complete a biography, subsequently provided to second- and third-year internal medicine residents. Residents were instructed to contact available mentors, and ultimately designate a formal mentor. All faculty and residents were provided a half-day workshop training, written guidelines, and e-mails. Reminders were e-mailed and announced in conferences approximately monthly. Residents were surveyed at the end of the academic year. Thirty-seven faculty members completed the biography, and 70% (26 of 37) of residents responded to the survey. Of the resident respondents, 77% (20 of 26) chose a formal mentor. Of the remainder, most had a previous informal mentor. Overall, 96% (25 of 26) of the residents had identified a mentor of some kind compared to 50% (13 of 26) before the intervention (P mentors identified them as actual mentors. Similar numbers of residents described their mentors as invested in the mentorship, and there was no statistical difference in the number of times mentors and mentees met. Facilitated selection of formal mentors produced relationships similar to preexisting informal ones. This model may increase the prevalence of mentorship without decreasing quality.

  7. Programming biological models in Python using PySB. (United States)

    Lopez, Carlos F; Muhlich, Jeremy L; Bachman, John A; Sorger, Peter K


    Mathematical equations are fundamental to modeling biological networks, but as networks get large and revisions frequent, it becomes difficult to manage equations directly or to combine previously developed models. Multiple simultaneous efforts to create graphical standards, rule-based languages, and integrated software workbenches aim to simplify biological modeling but none fully meets the need for transparent, extensible, and reusable models. In this paper we describe PySB, an approach in which models are not only created using programs, they are programs. PySB draws on programmatic modeling concepts from little b and ProMot, the rule-based languages BioNetGen and Kappa and the growing library of Python numerical tools. Central to PySB is a library of macros encoding familiar biochemical actions such as binding, catalysis, and polymerization, making it possible to use a high-level, action-oriented vocabulary to construct detailed models. As Python programs, PySB models leverage tools and practices from the open-source software community, substantially advancing our ability to distribute and manage the work of testing biochemical hypotheses. We illustrate these ideas using new and previously published models of apoptosis.

  8. Automatic generation of Fortran programs for algebraic simulation models

    International Nuclear Information System (INIS)

    Schopf, W.; Rexer, G.; Ruehle, R.


    This report documents a generator program by which econometric simulation models formulated in an application-orientated language can be transformed automatically in a Fortran program. Thus the model designer is able to build up, test and modify models without the need of a Fortran programmer. The development of a computer model is therefore simplified and shortened appreciably; in chapter 1-3 of this report all rules are presented for the application of the generator to the model design. Algebraic models including exogeneous and endogeneous time series variables, lead and lag function can be generated. In addition, to these language elements, Fortran sequences can be applied to the formulation of models in the case of complex model interrelations. Automatically the generated model is a module of the program system RSYST III and is therefore able to exchange input and output data with the central data bank of the system and in connection with the method library modules can be used to handle planning problems.

  9. Psychologist, physician and philosopher:the stages of P. Yа. Galperin’s scientific biography

    Directory of Open Access Journals (Sweden)

    Marina A. Stepanova


    Full Text Available The paper contains the description of Pyotr Ya. Galperin’s scientific biography stages. P.Ya. Galperin (1902–1988 is an outstanding Russian psychologist, the founder of an original psychological concept. The paper shows how P.Ya. Galperin’s scientific views were logically developing when he was working on the theory of gradual development of human intellectual activity that analyzes the process of constructing basic components of mental activity and creates the conditions for transforming the action into a psychological phenomenon. The biography is compiled on the basis of publications and talks of P.Ya. Galperin, the memories of colleagues and friends, using numerous archives. By now, only the main events in the life of a scientist have been marked. The paper presents the data that could be verified by referring to P.Yа. Galperin’s CV and data of the Academic Council of the Faculty of Psychology, Lomonosov Moscow State University, stored in the Archive of Lomonosov Moscow State University, and P.Yа. Galperin’s science archive passed by the grandson Yakov I. Abramson to the Archive of the Institute of Psychology of the Russian Academy of Sciences. The family archives failed to survive because of the frequent relocation, and P.Ya. Galperin did not write a detailed autobiography, so the task of clarifying the facts of his biography is relevant. All periods of P.Ya. Galperin’s scientific creative life are presented, his participation in scientific and practical events starting with the mid-1920s is mentioned. The 1930- 1940s are the most difficult years for event recovery. 55 years of professional and personal life (from 1943 and until his death in 1988 are associated with Lomonosov Moscow State University, therefore the focus is on P.Ya. Galperin as an outstanding Professor of Moscow University, i.e. the author of the original theory of the orientating nature and function of human mind, the organizing force in psychology. The

  12. Utility of Small Animal Models of Developmental Programming. (United States)

    Reynolds, Clare M; Vickers, Mark H


    Any effective strategy to tackle the global obesity and rising noncommunicable disease epidemic requires an in-depth understanding of the mechanisms that underlie these conditions that manifest as a consequence of complex gene-environment interactions. In this context, it is now well established that alterations in the early life environment, including suboptimal nutrition, can result in an increased risk for a range of metabolic, cardiovascular, and behavioral disorders in later life, a process preferentially termed developmental programming. To date, most of the mechanistic knowledge around the processes underpinning development programming has been derived from preclinical research performed mostly, but not exclusively, in laboratory mouse and rat strains. This review will cover the utility of small animal models in developmental programming, the limitations of such models, and potential future directions that are required to fully maximize information derived from preclinical models in order to effectively translate to clinical use.

The report also describes management concepts helpful in managing a technology transfer program.

  14. Transforming PLC Programs into Formal Models for Verification Purposes

    CERN Document Server

    Darvas, D; Blanco, E


    Most of CERN’s industrial installations rely on PLC-based (Programmable Logic Controller) control systems developed using the UNICOS framework. This framework contains common, reusable program modules and their correctness is a high priority. Testing is already applied to find errors, but this method has limitations. In this work an approach is proposed to transform automatically PLC programs into formal models, with the goal of applying formal verification to ensure their correctness. We target model checking which is a precise, mathematical-based method to check formalized requirements automatically against the system.

  15. Model-based automated testing of critical PLC programs.

    CERN Document Server

    Fernández Adiego, B; Tournier, J-C; González Suárez, V M; Bliudze, S


    Testing of critical PLC (Programmable Logic Controller) programs remains a challenging task for control system engineers as it can rarely be automated. This paper proposes a model based approach which uses the BIP (Behavior, Interactions and Priorities) framework to perform automated testing of PLC programs developed with the UNICOS (UNified Industrial COntrol System) framework. This paper defines the translation procedure and rules from UNICOS to BIP which can be fully automated in order to hide the complexity of the underlying model from the control engineers. The approach is illustrated and validated through the study of a water treatment process.

    Haxthausen, Anne Elisabeth; Peleska, Jan


    In this article, the feasibility of a unified modelling and programming paradigm is discussed from the perspective of large scale system development and verification in collaborative development environments. We motivate the necessity to utilise multiple formalisms for development and verification......, in particular for complex cyber-physical systems or systems of systems. Though modelling, programming, and verification will certainly become more closely integrated in the future, we do not expect a single formalism to become universally applicable and accepted by the development and verification communities...

    Energy Technology Data Exchange (ETDEWEB)

    Moore, Walter J.


    Erwin Schroedinger (1887-1961) was a pioneer of quantum physics, one of the most important scientist of the 20th century at all and a charming Austrian. He was a man with a passionate interest for men and ideas. Mostly known he became by his representation of quantum theory in the form of wave mechanics, for which he obtained the Nobel prize for physics and naturally by the famous thought experiment ''Schroedingers cat''. Walter Moore's biography is quite near to the person of Schroedinger and presents his scientific work in the context of his friendships, his interset for mysticism, and in front of the moving background of the political events in Germany and Austria.

    Full Text Available Muhammad ʿAbd al-Malik al-Mutawakkil (1942-2014, professor of political science at Sanaa University, deputy secretary-general of the Union of Popular Forces, and pioneer of the human rights movement in South Arabia, was one of the few home de lettres in Yemen whose intellectual clout extended far into the Arab world. As an outstanding figure of political and scholarly life in the southern tip of the Arabian Peninsula, his vita exemplifies the ups and downs of Yemeni politics in the post-imamic, republican era up to the fall of ʿAli ʿAbdallah Salih, just as his writings are an enlightening guide to the understanding of the latter and the Yemeni social fabric as a whole. This article seeks to provide a political biography of a man whose calm and sensible voice many will find missing in these times of turmoil.

    Full Text Available This article discusses the book Ecce homo, by Nietzsche, defending that the text is an interpretation of the philosopher himself on her own thought, not to give the book a sacred tone, nor to stress his biography, but affirming a dissonant thought that indicates his philosophical ambition. With no constraints, Nietzsche presents his conflicts, passions, deceptions, announcing a tragic dimension of life that is not guided by pessimism, but by happiness of living intensely, understanding suffering as one of the facets of life. His philosophy derives from a life demand, transfigured by an experience that promotes self cultivation and the possibility of “becoming what one really is” through the “applying” of one’s own genealogic method.

  4. Selective neurophysiologic responses to music in instrumentalists with different listening biographies. (United States)

    Margulis, Elizabeth Hellmuth; Mlsna, Lauren M; Uppunda, Ajith K; Parrish, Todd B; Wong, Patrick C M


    To appropriately adapt to constant sensory stimulation, neurons in the auditory system are tuned to various acoustic characteristics, such as center frequencies, frequency modulations, and their combinations, particularly those combinations that carry species-specific communicative functions. The present study asks whether such tunings extend beyond acoustic and communicative functions to auditory self-relevance and expertise. More specifically, we examined the role of the listening biography--an individual's long term experience with a particular type of auditory input--on perceptual-neural plasticity. Two groups of expert instrumentalists (violinists and flutists) listened to matched musical excerpts played on the two instruments (J.S. Bach Partitas for solo violin and flute) while their cerebral hemodynamic responses were measured using fMRI. Our experimental design allowed for a comprehensive investigation of the neurophysiology (cerebral hemodynamic responses as measured by fMRI) of auditory expertise (i.e., when violinists listened to violin music and when flutists listened to flute music) and nonexpertise (i.e., when subjects listened to music played on the other instrument). We found an extensive cerebral network of expertise, which implicates increased sensitivity to musical syntax (BA 44), timbre (auditory association cortex), and sound-motor interactions (precentral gyrus) when listening to music played on the instrument of expertise (the instrument for which subjects had a unique listening biography). These findings highlight auditory self-relevance and expertise as a mechanism of perceptual-neural plasticity, and implicate neural tuning that includes and extends beyond acoustic and communication-relevant structures.

  6. Unauthorised Biographies: An Analysis Under the Perspective of Robert Alexy's External Theory

    Directory of Open Access Journals (Sweden)

    Adriana Inomata


    Full Text Available The present paperwork aimed to analyse whether or not the publication of a biography should require the prior authorisation from the subject  or their family. As there is, in this case, a collision between personality rights and freedom of speech, the proportionality test was used to solve such conflict. The first step was to define biography as a non-ficctional genre. The paperwork then aimed to define the theory of the principles, the external theory of the restriction of fundamental rights and the proportionality test developed by jurist Robert Alexy, which are largely used in Brazil by authors like Virgílio Afonso da Silva, Ingo Wolfgang Sarlet and Daniel Sarmento. It was observed that when fundamental rights collide, the proportionality must be verified and as a result there is a conditional precedence relation between the rights. In such case, the ceding right will be restricted by the preciding one. The external theory is a recognised manner of verifying whether the restriction of a fundamental right is legit or if it is a violation. The need for prior authorisation, based on the personality protection, restricts freedom of speech, on the other hand, its exemption is based on the right to freedom of speech. By applying the aforementioned method, a particular rule was developed and the conditions for it to be applicable: freedom of speech prevails over personality rights in given conditions (public figure, over suitable means, no expectation for privacy in the publication, diligence in the verification of truth or social and journalistic interest over the information

    The previous research showed that there were indicators of water crisis in the northern and eastern part of Denpasar city and most of coastal area experienced on seawater intrusion. The recommended water conservation programs were rainwater harvesting and educate the community to develop a water saving and environmentally conscious culture. This research was conducted to built the community based educational model on water conservation program through ergonomics SHIP approach which placed the human aspect as the first consideration, besides the economic and technically aspects. The stakeholders involved in the program started from the problem analyses to the implementation and the maintenance as well. The model was built through three main steps, included determination of accepted design; building the recharge wells by involving local communities; guidance and assistance in developing a water saving and environmentally conscious culture for early childhood, elementary and junior high school students, community and industry. The program was implemented based on the “TRIHITA KARANA” concept, which means the relationship between human to God, human-to-human, and human to environment. Through the development of the model, it is expected to grow a sense of belonging and awareness from the community to maintain the sustainability of the program.

    Full Text Available The term "grandiose pseudo-clasicism", introduced to the study of fashion in socialism by Djurdja Bartlett, does not hold ground in the case of Yugoslav/Serbian offical fashion industry. Instead, I claim that a more appropriate term would be "grandiose exotism", since Yugoslav/Serbian fashion did not build its identity on the pseudoclassical esthetical models, but on the incorporation of exotic motives and patterns form the national thesaurus. "Grandiose exotism" was a part of the wider project of "national-style" fashion that dominated the history of Yugoslav/Serbian fashion during the 1960s. This form of fashion production was a convenient means for the presentation of Yugoslav idiosyncrasies. Since it corresponded with the characteristics of the social and political milieu of the Yugoslav state, "national-style" fashion symbolically represented the aspects of the identity of Yugoslavia as a socialist and non-aligned country. Therefore, the socialist regime gave a highly representative and commercialized role to grandiose exotism, as an exclusive style in national fashion. However, in the domain of everyday practices, exclusive fashion production was denied high cultural value, since its products were subjected to processes of commoditization and exchanged for very low sums of money. Parallel to the processes of commoditization, there was the process of informal singularization carried out by groups who had access to warehouse stocks of haute couture. Unfortunately, the lack of data on the further cultural biography of these objects disables us to fully study the destiny of exclusive pieces of Yugoslav fashion production in socialism.

  11. Menu variations for diabetes mellitus patients using Goal Programming model (United States)

    Dhoruri, Atmini; Lestari, Dwi; Ratnasari, Eminugroho


    Diabetes mellitus (DM) was a chronic metabolic disease characterized by higher than normal blood glucose level (normal blood glucose level = = 80 -120 mg/dl). In this study, type 2 DM which mostly caused by unhealthy eating habits would be investigated. Related to eating habit, DM patients needed dietary menu planning with an extracare regarding their nutrients intake (energy, protein, fat and carbohydrate). Therefore, the measures taken were by organizing nutritious dietary menu for diabetes mellitus patients. Dietary menu with appropriate amount of nutrients was organized by considering the amount of calories, proteins, fats and carbohydrates. In this study, Goal Programming model was employed to determine optimal dietary menu variations for diabetes mellitus patients by paying attention to optimal expenses. According to the data obtained from hospitals in Yogyakarta, optimal menu variations would be analyzed by using Goal Programming model and would be completed by using LINGO computer program.

  17. Supporting universal prevention programs: a two-phased coaching model. (United States)

    Becker, Kimberly D; Darney, Dana; Domitrovich, Celene; Keperling, Jennifer Pitchford; Ialongo, Nicholas S


    Schools are adopting evidence-based programs designed to enhance students' emotional and behavioral competencies at increasing rates (Hemmeter et al. in Early Child Res Q 26:96-109, 2011). At the same time, teachers express the need for increased support surrounding implementation of these evidence-based programs (Carter and Van Norman in Early Child Educ 38:279-288, 2010). Ongoing professional development in the form of coaching may enhance teacher skills and implementation (Noell et al. in School Psychol Rev 34:87-106, 2005; Stormont et al. 2012). There exists a need for a coaching model that can be applied to a variety of teacher skill levels and one that guides coach decision-making about how best to support teachers. This article provides a detailed account of a two-phased coaching model with empirical support developed and tested with coaches and teachers in urban schools (Becker et al. 2013). In the initial universal coaching phase, all teachers receive the same coaching elements regardless of their skill level. Then, in the tailored coaching phase, coaching varies according to the strengths and needs of each teacher. Specifically, more intensive coaching strategies are used only with teachers who need additional coaching supports, whereas other teachers receive just enough support to consolidate and maintain their strong implementation. Examples of how coaches used the two-phased coaching model when working with teachers who were implementing two universal prevention programs (i.e., the PATHS curriculum and PAX Good Behavior Game [PAX GBG]) provide illustrations of the application of this model. The potential reach of this coaching model extends to other school-based programs as well as other settings in which coaches partner with interventionists to implement evidence-based programs.

  18. Use of linear programming models in experimentation with plant nutrients

    Directory of Open Access Journals (Sweden)

    Mauro Brino Garcia


    Full Text Available Nutrition is an important issue of plant cultivation and experimentation with plant nutrients is a supporting tool for agriculture. However, use of high purity grade reagents as nutrient sources can be expensive and increases the cost of an experiment. The objective of this study was to minimize the acquisition cost of high purity grade reagents in experiments on plant nutrient deficiency by using the missing element technique through linear programming models, and to generate recommendation tables for preparation of culture solutions, as well as to quantify gains through a simulated experiment. Two linear programming models were formulated containing concentration constraints for each nutrient in the culture solution. Model A was based on 16 reagents for preparation of the culture solution, while model B was based on 27 reagents, looking to increase choice options. Results showed that both models minimized the acquisition cost of reagents, allowing a 9.03% reduction in model A and a 25.98% reduction in model B. The missing sulfur treatment proved the most costly for reagent acquisition while the missing nitrogen treatment proved the least costly. It was concluded that the formulated models were capable of reducing acquisition costs of reagents, yet the recommendations generated by them should be tested and checked for practical viability.

  19. Programming Models for Concurrency and Real-Time (United States)

    Vitek, Jan

    Modern real-time applications are increasingly large, complex and concurrent systems which must meet stringent performance and predictability requirements. Programming those systems require fundamental advances in programming languages and runtime systems. This talk presents our work on Flexotasks, a programming model for concurrent, real-time systems inspired by stream-processing and concurrent active objects. Some of the key innovations in Flexotasks are that it support both real-time garbage collection and region-based memory with an ownership type system for static safety. Communication between tasks is performed by channels with a linear type discipline to avoid copying messages, and by a non-blocking transactional memory facility. We have evaluated our model empirically within two distinct implementations, one based on Purdue’s Ovm research virtual machine framework and the other on Websphere, IBM’s production real-time virtual machine. We have written a number of small programs, as well as a 30 KLOC avionics collision detector application. We show that Flexotasks are capable of executing periodic threads at 10 KHz with a standard deviation of 1.2us and have performance competitive with hand coded C programs.

  20. A Programming Model for Massive Data Parallelism with Data Dependencies

    International Nuclear Information System (INIS)

    Cui, Xiaohui; Mueller, Frank; Potok, Thomas E.; Zhang, Yongpeng


    Accelerating processors can often be more cost and energy effective for a wide range of data-parallel computing problems than general-purpose processors. For graphics processor units (GPUs), this is particularly the case when program development is aided by environments such as NVIDIA s Compute Unified Device Architecture (CUDA), which dramatically reduces the gap between domain-specific architectures and general purpose programming. Nonetheless, general-purpose GPU (GPGPU) programming remains subject to several restrictions. Most significantly, the separation of host (CPU) and accelerator (GPU) address spaces requires explicit management of GPU memory resources, especially for massive data parallelism that well exceeds the memory capacity of GPUs. One solution to this problem is to transfer data between the GPU and host memories frequently. In this work, we investigate another approach. We run massively data-parallel applications on GPU clusters. We further propose a programming model for massive data parallelism with data dependencies for this scenario. Experience from micro benchmarks and real-world applications shows that our model provides not only ease of programming but also significant performance gains

  1. Modeling and prototyping of biometric systems using dataflow programming (United States)

    Minakova, N.; Petrov, I.


    The development of biometric systems is one of the labor-intensive processes. Therefore, the creation and analysis of approaches and techniques is an urgent task at present. This article presents a technique of modeling and prototyping biometric systems based on dataflow programming. The technique includes three main stages: the development of functional blocks, the creation of a dataflow graph and the generation of a prototype. A specially developed software modeling environment that implements this technique is described. As an example of the use of this technique, an example of the implementation of the iris localization subsystem is demonstrated. A variant of modification of dataflow programming is suggested to solve the problem related to the undefined order of block activation. The main advantage of the presented technique is the ability to visually display and design the model of the biometric system, the rapid creation of a working prototype and the reuse of the previously developed functional blocks.

  2. Hybrid programming model for implicit PDE simulations on multicore architectures

    KAUST Repository

    Kaushik, Dinesh


    The complexity of programming modern multicore processor based clusters is rapidly rising, with GPUs adding further demand for fine-grained parallelism. This paper analyzes the performance of the hybrid (MPI+OpenMP) programming model in the context of an implicit unstructured mesh CFD code. At the implementation level, the effects of cache locality, update management, work division, and synchronization frequency are studied. The hybrid model presents interesting algorithmic opportunities as well: the convergence of linear system solver is quicker than the pure MPI case since the parallel preconditioner stays stronger when hybrid model is used. This implies significant savings in the cost of communication and synchronization (explicit and implicit). Even though OpenMP based parallelism is easier to implement (with in a subdomain assigned to one MPI process for simplicity), getting good performance needs attention to data partitioning issues similar to those in the message-passing case. © 2011 Springer-Verlag.

    Many building stock models employ archetype-buildings in order to capture the essential characteristics of a diverse building stock. However, these models often require multiple archetypes, which make them inflexible. This paper proposes an array-programming based model, which calculates the heat...... demand of each building separately. This approach makes it possible to study any subset of the building stock without loss of information. Moreover, the calculated heat demand can readily be compared to a registered consumption in individual buildings to account for discrepancies. Results show, that we...

  6. An occupational medical program for a 'model' uranium mill

    International Nuclear Information System (INIS)

    Miller, H.T.


    The basic purpose of occupational health programs in uranium milling are to insure that no employee receives an exposure to carcinogenic, mutagenic, teratogenic, highly toxic, pneumoconiosis-producing, or dangerous physical agents that could result in chronic or acute injury and to assure that significant concentrations or levels of the above are not present in either the plant or general environment. This paper defines a model mill as consisting of crushing, sizing, acid leach, separation, solvent extraction, drying and packaging operations and describes the employee health hazards associated with each. It also describes a type program consisting of a balanced combination of exposure monitoring and survey, air samples, personnel dosimetry, bioassay, training, medical surveillance, and emergency planning based on the employee exposure situation. Experience with such a program is also discussed, and some techniques of practically meeting the regulatory requirements and protecting the worker are outlined. (Auth.)

    NUCIRC is a steady-state thermal-hydraulic code used for design and performance analyses of CANDU Heat Transport System. The code is used to build PHT model in Wolsong NPP and to calculate channel flow distribution. Wolsong NPP has to calculate channel flow distribution and quality of coolant at the ROH header after every outage by OPP (Operating Policy and Principal). PHT modeling work is time consuming which need a lot of operation experience and specialty. It is very difficult to build PHT model as plant operator in two weeks which is obligate for plant operation after every outage. That is why Wolsong NPP develop NUMODEL (NUcirc MODELing) with many-years experience and a know-how of using NUCIRC code. NUMODEL is computer program which is used to create PHT model based on utilizing NUCIRC code

    An effective office ergonomics program can predict positive results in reducing musculoskeletal injury rates, enhancing productivity, and improving staff well-being and job satisfaction. Its objective is to provide a systematic solution to manage the potential risk of musculoskeletal disorders among computer users in an office setting. A FITS Model office ergonomics program is developed. The FITS Model Office Ergonomics Program has been developed which draws on the legislative requirements for promoting the health and safety of workers using computers for extended periods as well as previous research findings. The Model is developed according to the practical industrial knowledge in ergonomics, occupational health and safety management, and human resources management in Hong Kong and overseas. This paper proposes a comprehensive office ergonomics program, the FITS Model, which considers (1) Furniture Evaluation and Selection; (2) Individual Workstation Assessment; (3) Training and Education; (4) Stretching Exercises and Rest Break as elements of an effective program. An experienced ergonomics practitioner should be included in the program design and implementation. Through the FITS Model Office Ergonomics Program, the risk of musculoskeletal disorders among computer users can be eliminated or minimized, and workplace health and safety and employees' wellness enhanced.

    Adrienne Kegye


    Full Text Available Background Patients receiving cancer treatment start lifestyle changes mostly at the end of the treatment during the rehabilitation period. Most often, the first step is a dietary change and physical exercises built into the daily routine. Patients who do this in groups led by qualified therapists and based on professional counseling can build more effective and more permanent changes into their life. To develop a complex rehabilitation program which, in the short term, aims to familiarize patients with a lifestyle which harmonizes the physical, mental, spiritual and social spheres of life and, in the long term, to build it into their everyday life in order to ameliorate the physical and mental state and reduce the psychological symptoms and the isolation of patients. The physical component focuses on diet and exercise. The psycho-social-spiritual support focuses on discovering inner sources of strength, developing active coping mechanisms and helping to achieve more open communication. Participants and procedure In February and March 2011, 8 patients treated for malignant tumors participated in the model program. The components of the model program were psychotherapy, physiotherapy, cancer consultation, nutrition counseling, creative activities and walking. Results During the period of the model program the isolation of the patients decreased and their social support and ability of coping with the illness ameliorated. They reported an ease in anxiety and depression in their everyday activities. According to feedback, their communication with each other, with the staff and with their relatives became more open. Altogether this had advantageous effects on the functioning of the ward and the mood of the staff. Conclusions The rehabilitation program confirmed that beside individual psycho-social support, beneficial and economic psycho-social support can be provided for the patients in group form along with the most effective assignment of the

A different view is appropriate to a wide class of problem, perhaps including some problems in High Energy Physics. The programmer's task is regarded as having three main stages: first, an explicit model is constructed of the reality with which the program is concerned; second, this model is elaborated to produce the required program outputs; third, the resulting program is transformed to run efficiently in the execution environment. The first two stages deal in network structures of sequential processes; only the third is concerned with procedure hierarchies. (orig.)

The programmer's task is regarded as having three main stages: first, an explicit model is constructed of the reality with which the program is concerned; second, this model is elaborated to produce the required program outputs; third, the resulting program is transformed to run efficiently in the execution environment. The first two stages deal in network structures of sequential processes; only the third is concerned with procedure hierarchies.

  17. Using Runtime Analysis to Guide Model Checking of Java Programs (United States)

    Havelund, Klaus; Norvig, Peter (Technical Monitor)


    This paper describes how two runtime analysis algorithms, an existing data race detection algorithm and a new deadlock detection algorithm, have been implemented to analyze Java programs. Runtime analysis is based on the idea of executing the program once. and observing the generated run to extract various kinds of information. This information can then be used to predict whether other different runs may violate some properties of interest, in addition of course to demonstrate whether the generated run itself violates such properties. These runtime analyses can be performed stand-alone to generate a set of warnings. It is furthermore demonstrated how these warnings can be used to guide a model checker, thereby reducing the search space. The described techniques have been implemented in the b e grown Java model checker called PathFinder.

  18. Comparison of Building Energy Modeling Programs: Building Loads

    Energy Technology Data Exchange (ETDEWEB)

    Zhu, Dandan [Tsinghua Univ., Beijing (China); Hong, Tianzhen [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Yan, Da [Tsinghua Univ., Beijing (China); Wang, Chuang [Tsinghua Univ., Beijing (China)


    This technical report presented the methodologies, processes, and results of comparing three Building Energy Modeling Programs (BEMPs) for load calculations: EnergyPlus, DeST and DOE-2.1E. This joint effort, between Lawrence Berkeley National Laboratory, USA and Tsinghua University, China, was part of research projects under the US-China Clean Energy Research Center on Building Energy Efficiency (CERC-BEE). Energy Foundation, an industrial partner of CERC-BEE, was the co-sponsor of this study work. It is widely known that large discrepancies in simulation results can exist between different BEMPs. The result is a lack of confidence in building simulation amongst many users and stakeholders. In the fields of building energy code development and energy labeling programs where building simulation plays a key role, there are also confusing and misleading claims that some BEMPs are better than others. In order to address these problems, it is essential to identify and understand differences between widely-used BEMPs, and the impact of these differences on load simulation results, by detailed comparisons of these BEMPs from source code to results. The primary goal of this work was to research methods and processes that would allow a thorough scientific comparison of the BEMPs. The secondary goal was to provide a list of strengths and weaknesses for each BEMP, based on in-depth understandings of their modeling capabilities, mathematical algorithms, advantages and limitations. This is to guide the use of BEMPs in the design and retrofit of buildings, especially to support China’s building energy standard development and energy labeling program. The research findings could also serve as a good reference to improve the modeling capabilities and applications of the three BEMPs. The methodologies, processes, and analyses employed in the comparison work could also be used to compare other programs. The load calculation method of each program was analyzed and compared to

  3. An integer programming model for distal humerus fracture fixation planning. (United States)

    Maratt, Joseph D; Peaks, Ya-Sin A; Doro, Lisa Case; Karunakar, Madhav A; Hughes, Richard E


    To demonstrate the feasibility of an integer programming model to assist in pre-operative planning for open reduction and internal fixation of a distal humerus fracture. We describe an integer programming model based on the objective of maximizing the reward for screws placed while satisfying the requirements for sound internal fixation. The model maximizes the number of bicortical screws placed while avoiding screw collision and favoring screws of greater length that cross multiple fracture planes. The model was tested on three types of total articular fractures of the distal humerus. Solutions were generated using 5, 9, 21 and 33 possible screw orientations per hole. Solutions generated using 33 possible screw orientations per hole and five screw lengths resulted in the most clinically relevant fixation plan and required the calculation of 1,191,975 pairs of screws that resulted in collision. At this level of complexity, the pre-processor took 104 seconds to generate the constraints for the solver, and a solution was generated in under one minute in all three cases. Despite the large size of this problem, it can be solved in a reasonable amount of time, making use of the model practical in pre-surgical planning.

    We present an extension of the programming-by-contract (PBC) paradigm to a concurrent and distributed environment.  Classical PBC is characterized by absolute conformance of code to its specification, assigning blame in case of failures, and a hierarchical, cooperative decomposition model – none...... of which extend naturally to a distributed environment with multiple administrative peers. We therefore propose a more nuanced contract model based on quantifiable performance of implementations; assuming responsibility for success; and a fundamentally adversarial model of system integration, where each...... component provider is optimizing its behavior locally, with respect to potentially conflicting demands.  This model gives rise to a game-theoretic formulation of contract-governed process interactions that supports compositional reasoning about contract conformance....

  7. A model for a national low level waste program

    International Nuclear Information System (INIS)

    Blankenhorn, James A.


    A national program for the management of low level waste is essential to the success of environmental clean-up, decontamination and decommissioning, current operations and future missions. The value of a national program is recognized through procedural consistency and a shared set of resources. A national program requires a clear waste definition and an understanding of waste characteristics matched against available and proposed disposal options. A national program requires the development and implementation of standards and procedures for implementing the waste hierarchy, with a specitic emphasis on waste avoidance, minimization and recycling. It requires a common set of objectives for waste characterization based on the disposal facility's waste acceptance criteria, regulatory and license requirements and performance assessments. Finally, a national waste certification program is required to ensure compliance. To facilitate and enhance the national program, a centralized generator services organization, tasked with providing technical services to the generators on behalf of the national program, is necessary. These subject matter experts are the interface between the generating sites and the disposal facility(s). They provide an invaluable service to the generating organizations through their involvement in waste planning prior to waste generation and through championing implementation of the waste hierarchy. Through their interface, national treatment and transportation services are optimized and new business opportunities are identified. This national model is based on extensive experience in the development and on-going management of a national transuranic waste program and management of the national repository, the Waste Isolation Pilot Plant. The Low Level Program at the Savannah River Site also successfully developed and implemented the waste hierarchy, waste certification and waste generator services concepts presented below.

  8. Balancing Biography and Institutional History: Eric Worrell’s Australian Reptile Park

    Directory of Open Access Journals (Sweden)

    Nancy Cushing


    Full Text Available When a young naturalist opened his new wildlife park at Wyoming on the NSW Central Coast in the late 1950s, he gave it his own name: Eric Worrell’s Australian Reptile Park. Through the park, Worrell made a significant contribution to environmental education, the development of knowledge of captive animal care and display and the provision of antivenoms for the bites of a range of dangerous creatures. More than this, it was the geographic and emotional centre of Worrell’s world: the fulfilment of a childhood dream, a home for his family and a site for forming new personal and professional relationships. In preparation for the jubilee of the park, its history is being written by two academics from the University of Newcastle. An attractive means of creating the necessary narrative structure and human interest to ensure the wide appeal of this history is to follow Worrell’s lead and place his life at the centre of this institutional history. This is the direction suggested by the written sources on the park and it is accentuated by many of our oral informants who organise their memories of the park around Worrell. To what extent can an institutional history be a biography of the person at the heart of that institution? Is it possible to disentangle the life from the institution? This article offers some preliminary answers to these questions through a case study of the writing of a history of Eric Worrell’s Australian Reptile Park.

  9. Biography, policy and language teaching practices in a multilingual context: Early childhood classrooms in Mauritius

    Directory of Open Access Journals (Sweden)

    Aruna Ankiah-Gangadeen


    Full Text Available Language policies in education in multilingual postcolonial contexts are often driven by ideological considerations more veered towards socio-economic and political viability for the country than towards the practicality at implementation level. Centuries after the advent of colonisation, when culturally and linguistically homogenous countries helped to maintain the dominion of colonisers, the English language still has a stronghold in numerous countries due to the material rewards it offers. How then are the diversity of languages – often with different statuses and functions in society – reconciled in the teaching and learning process? How do teachers deal with the intricacies that are generated within a situation where children are taught in a language that is foreign to them? This paper is based on a study involving pre-primary teachers in Mauritius, a developing multilingual African country. The aim was to understand how their approach to the teaching of English was shaped by their biographical experiences of learning the language. The narrative inquiry methodology offered rich possibilities to foray into these experiences, including the manifestations of negotiating their classroom pedagogy in relation to their own personal historical biographies of language teaching and learning, the policy environment, and the pragmatic classroom specificities of diverse, multilingual learners. These insights become resources for early childhood education and teacher development in multilingual contexts caught within the tensions between language policy and pedagogy.

    Full Text Available On the basis of previously published author’s works about biographies of individual ships, considered Russian-Spanish ship’s exchange as an aspect of naval cooperation between Russia and Spain. There is offer a periodization of this process. The first period (1810-1820-s. associated with the sale for the Spanish fleet the Russian Baltic Fleet at the end of the Napoleonic wars, that reasons were on the needing to regain the Spanish colonies in Latin America. On two parties there were purchased five battleships and six frigates. The second period (1904-1917 associated with negotiations for the purchasing for Russian a Spanish warships during the Russian-Japanese war, and the acquisition of five Spanish trawlers in 1915 for the needs of the Arctic Ocean Flotilla. The third period (1936-1939 – mutual capture of merchant vessels and the Soviet aid for Republican Spain, when it was handed over to four torpedo boats G-5-class, two of which at the end of the Civil War were served in the Nationalists Navy.

  11. Constructing history in biography: a symposium on William Osler: a life in medicine. Introduction. (United States)

    Lella, J W


    William Osler's medical career spanned two centuries and three nations: Canada, the United States, and Great Britain. Though not an especially noted scientist, he was an innovative teacher, a professional organizer, and mentor and colleague to many grateful--indeed, sometimes adoring--students and colleagues, some of whom became influential in the Anglo-Saxon medical world. Since his death, Osler has been the subject of an enormous body of literature, fed by numerous Osler societies throughout the world. Among these is the American Osler Society, upon whose recent review panel this symposium is based. In it, three Oslerians--Philip Teigen, Earl Nation, and Joseph Lella--use Michael Bliss's book as the starting point for reading historical themes in Osler's life from their own standpoints. Bliss responds to these views by stressing the factual underpinnings of his book and by interpreting it, the first major biography of Osler since Cushing, in the context of his other works in the history of medicine as another study of the emergence of "health care as a secular replacement for traditional religious faith in the supernatural."

  12. The psychosocial impacts of multimedia biographies on persons with cognitive impairments. (United States)

    Damianakis, Thecla; Crete-Nishihata, Masashi; Smith, Karen L; Baecker, Ronald M; Marziali, Elsa


    The purpose of this feasibility pilot project was to observe Alzheimer's disease (AD) and mild cognitive impairment (MCI) patients' responses to personalized multimedia biographies (MBs). We developed a procedure for using digital video technology to construct DVD-based MBs of persons with AD or MCI, documented their responses to observing their MBs, and evaluated the psychosocial benefits. An interdisciplinary team consisting of multimedia biographers and social workers interviewed 12 family members of persons with AD and MCI and collected archival materials to best capture the families' and patients' life histories. We filmed patients' responses to watching the MBs and conducted follow-up interviews with the families and patients at 3 and 6 months following the initial viewing. Qualitative analytic strategies were used for extracting themes and key issues identified in both the filmed and the interview response data. Analysis of the interview and video data showed how evoked long-term memories stimulated reminiscing, brought mostly joy but occasionally moments of sadness to the persons with cognitive impairments, aided family members in remembering and better understanding their loved ones, and stimulated social interactions with family members and with formal caregivers. This study demonstrates the feasibility of using readily available digital video technology to produce MBs that hold special meaning for individuals experiencing AD or MCI and their families.

  13. Optical Neural Network Models Applied To Logic Program Execution (United States)

    Stormon, Charles D.


    Logic programming is being used extensively by Artificial Intelligence researchers to solve problems including natural language processing and expert systems. These languages, of which Prolog is the most widely used, promise to revolutionize software engineering, but much greater performance is needed. Researchers have demonstrated the applicability of neural network models to the solution of certain NP-complete problems, but these methods are not obviously applicable to the execution of logic programs. This paper outlines the use of neural networks in four aspects of the logic program execution cycle, and discusses results of a simulation of three of these. Four neural network functional units are described, called the substitution agent, the clause filter, the structure processor, and the heuristics generator, respectively. Simulation results suggest that the system described may provide several orders of magnitude improvement in execution speed for large logic programs. However, practical implementation of the proposed architecture will require the application of optical computing techniques due to the large number of neurons required, and the need for massive, adaptive connectivity.

  14. Evaluation of Medical Education virtual Program: P3 model. (United States)

    Rezaee, Rita; Shokrpour, Nasrin; Boroumand, Maryam


    In e-learning, people get involved in a process and create the content (product) and make it available for virtual learners. The present study was carried out in order to evaluate the first virtual master program in medical education at Shiraz University of Medical Sciences according to P3 Model. This is an evaluation research study with post single group design used to determine how effective this program was. All students 60 who participated more than one year in this virtual program and 21 experts including teachers and directors participated in this evaluation project. Based on the P3 e-learning model, an evaluation tool with 5-point Likert rating scale was designed and applied to collect the descriptive data. Students reported storyboard and course design as the most desirable element of learning environment (2.30±0.76), but they declared technical support as the less desirable part (1.17±1.23). Presence of such framework in this regard and using it within the format of appropriate tools for evaluation of e-learning in universities and higher education institutes, which present e-learning curricula in the country, may contribute to implementation of the present and future e-learning curricula efficiently and guarantee its implementation in an appropriate way.

  15. Genetic Programming and Standardization in Water Temperature Modelling

    Directory of Open Access Journals (Sweden)

    Maritza Arganis


    Full Text Available An application of Genetic Programming (an evolutionary computational tool without and with standardization data is presented with the aim of modeling the behavior of the water temperature in a river in terms of meteorological variables that are easily measured, to explore their explanatory power and to emphasize the utility of the standardization of variables in order to reduce the effect of those with large variance. Recorded data corresponding to the water temperature behavior at the Ebro River, Spain, are used as analysis case, showing a performance improvement on the developed model when data are standardized. This improvement is reflected in a reduction of the mean square error. Finally, the models obtained in this document were applied to estimate the water temperature in 2004, in order to provide evidence about their applicability to forecasting purposes.

  16. Mathematical model for HIV spreads control program with ART treatment (United States)

    Maimunah; Aldila, Dipo


    In this article, using a deterministic approach in a seven-dimensional nonlinear ordinary differential equation, we establish a mathematical model for the spread of HIV with an ART treatment intervention. In a simplified model, when no ART treatment is implemented, disease-free and the endemic equilibrium points were established analytically along with the basic reproduction number. The local stability criteria of disease-free equilibrium and the existing criteria of endemic equilibrium were analyzed. We find that endemic equilibrium exists when the basic reproduction number is larger than one. From the sensitivity analysis of the basic reproduction number of the complete model (with ART treatment), we find that the increased number of infected humans who follow the ART treatment program will reduce the basic reproduction number. We simulate this result also in the numerical experiment of the autonomous system to show how treatment intervention impacts the reduction of the infected population during the intervention time period.

  17. Stochastic programming framework for Lithuanian pension payout modelling

    Directory of Open Access Journals (Sweden)

    Audrius Kabašinskas


    Full Text Available The paper provides a scientific approach to the problem of selecting a pension fund by taking into account some specific characteristics of the Lithuanian Republic (LR pension accumulation system. The decision making model, which can be used to plan a long-term pension accrual of the Lithuanian Republic (LR citizens, in an optimal way is presented. This model focuses on factors that influence the sustainability of the pension system selection under macroeconomic, social and demographic uncertainty. The model is formalized as a single stage stochastic optimization problem where the long-term optimal strategy can be obtained based on the possible scenarios generated for a particular participant. Stochastic programming methods allow including the pension fund rebalancing moment and direction of investment, and taking into account possible changes of personal income, changes of society and the global financial market. The collection of methods used to generate scenario trees was found useful to solve strategic planning problems.

  18. Mathematical Modeling of Intestinal Iron Absorption Using Genetic Programming. (United States)

    Colins, Andrea; Gerdtzen, Ziomara P; Nuñez, Marco T; Salgado, J Cristian


    Iron is a trace metal, key for the development of living organisms. Its absorption process is complex and highly regulated at the transcriptional, translational and systemic levels. Recently, the internalization of the DMT1 transporter has been proposed as an additional regulatory mechanism at the intestinal level, associated to the mucosal block phenomenon. The short-term effect of iron exposure in apical uptake and initial absorption rates was studied in Caco-2 cells at different apical iron concentrations, using both an experimental approach and a mathematical modeling framework. This is the first report of short-term studies for this system. A non-linear behavior in the apical uptake dynamics was observed, which does not follow the classic saturation dynamics of traditional biochemical models. We propose a method for developing mathematical models for complex systems, based on a genetic programming algorithm. The algorithm is aimed at obtaining models with a high predictive capacity, and considers an additional parameter fitting stage and an additional Jackknife stage for estimating the generalization error. We developed a model for the iron uptake system with a higher predictive capacity than classic biochemical models. This was observed both with the apical uptake dataset used for generating the model and with an independent initial rates dataset used to test the predictive capacity of the model. The model obtained is a function of time and the initial apical iron concentration, with a linear component that captures the global tendency of the system, and a non-linear component that can be associated to the movement of DMT1 transporters. The model presented in this paper allows the detailed analysis, interpretation of experimental data, and identification of key relevant components for this complex biological process. This general method holds great potential for application to the elucidation of biological mechanisms and their key components in other complex

  20. C++, objected-oriented programming, and astronomical data models (United States)

    Farris, A.


    Contemporary astronomy is characterized by increasingly complex instruments and observational techniques, higher data collection rates, and large data archives, placing severe stress on software analysis systems. The object-oriented paradigm represents a significant new approach to software design and implementation that holds great promise for dealing with this increased complexity. The basic concepts of this approach will be characterized in contrast to more traditional procedure-oriented approaches. The fundamental features of objected-oriented programming will be discussed from a C++ programming language perspective, using examples familiar to astronomers. This discussion will focus on objects, classes and their relevance to the data type system; the principle of information hiding; and the use of inheritance to implement generalization/specialization relationships. Drawing on the object-oriented approach, features of a new database model to support astronomical data analysis will be presented.

  2. Optimal timing of joint replacement using mathematical programming and stochastic programming models. (United States)

    Keren, Baruch; Pliskin, Joseph S


    The optimal timing for performing radical medical procedures as joint (e.g., hip) replacement must be seriously considered. In this paper we show that under deterministic assumptions the optimal timing for joint replacement is a solution of a mathematical programming problem, and under stochastic assumptions the optimal timing can be formulated as a stochastic programming problem. We formulate deterministic and stochastic models that can serve as decision support tools. The results show that the benefit from joint replacement surgery is heavily dependent on timing. Moreover, for a special case where the patient's remaining life is normally distributed along with a normally distributed survival of the new joint, the expected benefit function from surgery is completely solved. This enables practitioners to draw the expected benefit graph, to find the optimal timing, to evaluate the benefit for each patient, to set priorities among patients and to decide if joint replacement should be performed and when.

  4. A Stochastic Programming Model for Fuel Treatment Management

    Directory of Open Access Journals (Sweden)

    Mohannad Kabli


    Full Text Available This work considers a two-stage stochastic integer programming (SIP approach for optimizing fuel treatment planning under uncertainty in weather and fire occurrence for rural forests. Given a set of areas for potentially performing fuel treatment, the problem is to decide the best treatment option for each area under uncertainty in future weather and fire occurrence. A two-stage SIP model is devised whose objective is to minimize the here-and-now cost of fuel treatment in the first-stage, plus the expected future costs due to uncertain impact from potential fires in the second-stage calculated as ecosystem services losses. The model considers four fuel treatment options: no treatment, mechanical thinning, prescribed fire, and grazing. Several constraints such as budgetary and labor constraints are included in the model and a standard fire behavior model is used to estimate some of the parameters of the model such as fuel levels at the beginning of the fire season. The SIP model was applied to data for a study area in East Texas with 15 treatment areas under different weather scenarios. The results of the study show, for example, that unless the expected ecosystem services values for an area outweigh fuel treatment costs, no treatment is the best choice for the area. Thus the valuation of the area together with the probability of fire occurrence and behavior strongly drive fuel treatment choices.

  7. Groundwater modelling of Aespoe using the ECLIPSE program

    Energy Technology Data Exchange (ETDEWEB)

    Wokil, H.


    The pre-investigations indicated that the dominant rocks ranged in composition from true granite to dioritic or gabbroic rocks. In conjunction with these investigations at the area, a number of indications were obtained of high transmissive fracture zones. To be able to understand the fracture zone NE-1 as well as possible, a number of hydraulic tests were performed, for example a tracer test. The program ECLIPSE 100 is one of the standard programs in the oil industry which is used to simulate oil fields. ECLIPSE 100 is a multi-facility simulator and it can be used to simulate 1, 2 and 3 phase systems, one option is oil, two phase options are oil/gas, oil/water or gas/water, and the third option is oil/gas/water. Good results were obtained from the simulator match of the tracer concentration versus time to the measured values from the tracer test of the fracture zone NE-1. The simulation was less successful in modelling the draw-down of water in the wells. We were also unable to reach a balance situation for the water pressure prior to injecting the tracer in order to accommodate several weeks of leakage into the tunnel prior to the tracer test. As a main conclusion, we found the results of the simulation to be satisfactory and we believe that further work should be done to adapt the program completely for groundwater simulation. 19 refs, 10 tabs, 13 figs.

  8. Cooperative Fish and Wildlife Research Units - A model partnership program (United States)

    Dennerline, Donald E.; Childs, Dawn E.


    The U.S. Geological Survey (USGS) Cooperative Fish and Wildlife Research Units (CRU) program is a unique model of cooperative partnership among the USGS, other U.S. Department of the Interior and Federal agencies, universities, State fish and wildlife agencies, and the Wildlife Management Institute. These partnerships are maintained as one of the USGS’s strongest links to Federal and State land and natural resource management agencies.Established in 1935 to meet the need for trained professionals in the growing field of wildlife management, the program currently consists of 40 Cooperative Fish and Wildlife Research Units located on university campuses in 38 States and supports 119 research scientist positions when fully funded. The threefold mission of the CRU program is to (1) conduct scientific research for the management of fish, wildlife, and other natural resources; (2) provide technical assistance to natural resource managers in the application of scientific information to natural resource policy and management; and (3) train future natural resource professionals.

  9. Faculty development program models to advance teaching and learning within health science programs. (United States)

    Lancaster, Jason W; Stein, Susan M; MacLean, Linda Garrelts; Van Amburgh, Jenny; Persky, Adam M


    Within health science programs there has been a call for more faculty development, particularly for teaching and learning. The primary objectives of this review were to describe the current landscape for faculty development programs for teaching and learning and make recommendations for the implementation of new faculty development programs. A thorough search of the pertinent health science databases was conducted, including the Education Resource Information Center (ERIC), MEDLINE, and EMBASE, and faculty development books and relevant information found were reviewed in order to provide recommendations for best practices. Faculty development for teaching and learning comes in a variety of forms, from individuals charged to initiate activities to committees and centers. Faculty development has been effective in improving faculty perceptions on the value of teaching, increasing motivation and enthusiasm for teaching, increasing knowledge and behaviors, and disseminating skills. Several models exist that can be implemented to support faculty teaching development. Institutions need to make informed decisions about which plan could be most successfully implemented in their college or school.

  10. Integer programming model for optimizing bus timetable using genetic algorithm (United States)

    Wihartiko, F. D.; Buono, A.; Silalahi, B. P.


    Bus timetable gave an information for passengers to ensure the availability of bus services. Timetable optimal condition happened when bus trips frequency could adapt and suit with passenger demand. In the peak time, the number of bus trips would be larger than the off-peak time. If the number of bus trips were more frequent than the optimal condition, it would make a high operating cost for bus operator. Conversely, if the number of trip was less than optimal condition, it would make a bad quality service for passengers. In this paper, the bus timetabling problem would be solved by integer programming model with modified genetic algorithm. Modification was placed in the chromosomes design, initial population recovery technique, chromosomes reconstruction and chromosomes extermination on specific generation. The result of this model gave the optimal solution with accuracy 99.1%.

  11. ModelArchiver—A program for facilitating the creation of groundwater model archives (United States)

    Winston, Richard B.


    ModelArchiver is a program designed to facilitate the creation of groundwater model archives that meet the requirements of the U.S. Geological Survey (USGS) policy (Office of Groundwater Technical Memorandum 2016.02,, ModelArchiver version 1.0 leads the user step-by-step through the process of creating a USGS groundwater model archive. The user specifies the contents of each of the subdirectories within the archive and provides descriptions of the archive contents. Descriptions of some files can be specified automatically using file extensions. Descriptions also can be specified individually. Those descriptions are added to a readme.txt file provided by the user. ModelArchiver moves the content of the archive to the archive folder and compresses some folders into .zip files.As part of the archive, the modeler must create a metadata file describing the archive. The program has a built-in metadata editor and provides links to websites that can aid in creation of the metadata. The built-in metadata editor is also available as a stand-alone program named FgdcMetaEditor version 1.0, which also is described in this report. ModelArchiver updates the metadata file provided by the user with descriptions of the files in the archive. An optional archive list file generated automatically by ModelMuse can streamline the creation of archives by identifying input files, output files, model programs, and ancillary files for inclusion in the archive.

  12. Optimizing Crawler4j using MapReduce Programming Model (United States)

    Siddesh, G. M.; Suresh, Kavya; Madhuri, K. Y.; Nijagal, Madhushree; Rakshitha, B. R.; Srinivasa, K. G.


    World wide web is a decentralized system that consists of a repository of information on the basis of web pages. These web pages act as a source of information or data in the present analytics world. Web crawlers are used for extracting useful information from web pages for different purposes. Firstly, it is used in web search engines where the web pages are indexed to form a corpus of information and allows the users to query on the web pages. Secondly, it is used for web archiving where the web pages are stored for later analysis phases. Thirdly, it can be used for web mining where the web pages are monitored for copyright purposes. The amount of information processed by the web crawler needs to be improved by using the capabilities of modern parallel processing technologies. In order to solve the problem of parallelism and the throughput of crawling this work proposes to optimize the Crawler4j using the Hadoop MapReduce programming model by parallelizing the processing of large input data. Crawler4j is a web crawler that retrieves useful information about the pages that it visits. The crawler Crawler4j coupled with data and computational parallelism of Hadoop MapReduce programming model improves the throughput and accuracy of web crawling. The experimental results demonstrate that the proposed solution achieves significant improvements with respect to performance and throughput. Hence the proposed approach intends to carve out a new methodology towards optimizing web crawling by achieving significant performance gain.

  13. Academic Biography in the Context of the Anti-Formalist Campaign of the 1930s

    Directory of Open Access Journals (Sweden)

    Yelena N. Penskaya


    Full Text Available The paper is focused around two biographical themes. Theme one is history of demolishing Leningrad school of dramatic theory developed in the State Institute of History of Art (GIII in the 1920s. In 1931, the GIII was closed by a Sovnarkom resolution and transformed into Len- ingrad division of the State Academy of Art Studies (LOGAIS established by the same resolu- tion. Theme two is description of the ‘academic traumatism’, traumatic behavior and its bio- graphical effects caused by destruction of a whole scientific trend during the anti-formalism campaign of the early 1930s. Based on archival documents (from the Russian State Archive of Literature and Art, shorthand notes and reports on discussions of the 1930s, we analyze behav- ioral tactics of initiators, participants and victims of the longstanding stigmatization and catalog absolutory, denunciative and repentant narratives. In particular, this paper analyzes the un- published letter to the editors of Rabochiy i Teatr journal written by Alexander Slonimsky, one of the key players in development and obliteration of dramatic theory associated primarily with Alexei Gvozdev’s group and with transformation and dissolution of the leading humanities in- stitutes. The text of the letter appears to be engrained in the complicated mosaic of measures aimed to discredit Meyerhold’s theater practice and Gvozdev as the leader of the scientific school. Deliberate misinterpretation and corruption of self-descriptions along with reconstruc- tion of biographies are some of the most crucial factors that affected reception of cultural pro- jects and their creators in the 1930s and later.

  14. A Biography of Distinguished Scientist Gilbert Newton Lewis (by Edward S. Lewis) (United States)

    Harris, Reviewed By Harold H.


    until 1904, when he accepted a position that would not be considered a shrewd career move: Superintendent of Weights and Measures in Manila, Philippines! He was there only one year, but it was apparently a productive time, both in a minimally equipped laboratory and with the possible nascence of some of his ideas about bonding. In 1905, Lewis accepted a staff position at MIT, under A. A. Noyes, where he remained until 1912. At MIT, he continued his experimental work on thermodynamic systems and the development of modern thermodynamics, following the lead of J. W. Gibbs, whose work was being largely ignored by other chemists. As Noyes moved increasingly into administrative responsibilities, Lewis took over more and more of the supervision of scientific work in the laboratory. It was the capable job that he did for Noyes that led to his being offered a Professorship and Chair of the College of Chemistry at the University of California, Berkeley. The same spirit of adventure that took Lewis to Manila may be what led to his moving to scientifically backward California. In 1912, there was no serious science going on the Left Coast, and Berkeley was isolated from the nearest civilization (Chicago) by days of travel. Lewis initiated the expansion of great science westward, not only to Berkeley, but also to Caltech (in those days Throop Institute), UCLA, and Stanford. By dint of his contributions to thermodynamics and bonding theory (suggesting that electrons bond in pairs, long before there was quantum mechanical justification for such a strange idea), and his organizational and leadership talents, he turned the Berkeley Chemistry Department from a nonentity into one of the finest anywhere. Later in his career, he contributed to the understanding of the role of isotopes in chemistry and physics. This biography includes a useful listing of Lewis's 168 scientific publications. In an age when many renowned scientists have multiples of this number, it is perhaps good to be

  15. Replacement model of city bus: A dynamic programming approach (United States)

    Arifin, Dadang; Yusuf, Edhi


    This paper aims to develop a replacement model of city bus vehicles operated in Bandung City. This study is driven from real cases encountered by the Damri Company in the efforts to improve services to the public. The replacement model propounds two policy alternatives: First, to maintain or keep the vehicles, and second is to replace them with new ones taking into account operating costs, revenue, salvage value, and acquisition cost of a new vehicle. A deterministic dynamic programming approach is used to solve the model. The optimization process was heuristically executed using empirical data of Perum Damri. The output of the model is to determine the replacement schedule and the best policy if the vehicle has passed the economic life. Based on the results, the technical life of the bus is approximately 20 years old, while the economic life is an average of 9 (nine) years. It means that after the bus is operated for 9 (nine) years, managers should consider the policy of rejuvenation.

  16. Parallel phase model : a programming model for high-end parallel machines with manycores.

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Junfeng (Syracuse University, Syracuse, NY); Wen, Zhaofang; Heroux, Michael Allen; Brightwell, Ronald Brian


    This paper presents a parallel programming model, Parallel Phase Model (PPM), for next-generation high-end parallel machines based on a distributed memory architecture consisting of a networked cluster of nodes with a large number of cores on each node. PPM has a unified high-level programming abstraction that facilitates the design and implementation of parallel algorithms to exploit both the parallelism of the many cores and the parallelism at the cluster level. The programming abstraction will be suitable for expressing both fine-grained and coarse-grained parallelism. It includes a few high-level parallel programming language constructs that can be added as an extension to an existing (sequential or parallel) programming language such as C; and the implementation of PPM also includes a light-weight runtime library that runs on top of an existing network communication software layer (e.g. MPI). Design philosophy of PPM and details of the programming abstraction are also presented. Several unstructured applications that inherently require high-volume random fine-grained data accesses have been implemented in PPM with very promising results.

  17. Changing community health behaviors: a model for program development and management. (United States)

    Hargreaves, M R; Laitakari, J K; Huff, F; Rautaharju, P M


    A model has been proposed to improve program development and management of behavior change programs with large-scale community impact. It can be applied to epidemiologic problems of which lifestyle is an important component, such as heart disease, adolescent pregnancy, hypertension, weight control, and cancer control and prevention programs. The model combines two previously existing models: one indicating that program development is an ongoing cyclical process which starts with uncertainty yet can progress to institutionalization with suitable testing; and the second model indicating that program management within each developmental cycle progresses through specific phases which can be hampered by plateaus and setbacks. Nine systems are essential for program development and operations: education (philosophy, objectives, and content), communications, reward, intervention, program process, program development, and program evaluation. These systems can be used as a guide to facilitate selection from the many guidelines recommended in the literature, and to ensure coordination of innovative program elements.

  18. Lytton Strachey, a Rebellious Man of Peculiarity: A Review of Holroyd’s Lytton Strachey: The New Biography

    Directory of Open Access Journals (Sweden)

    Qinchao Xu


    Full Text Available Lytton Strachey: The New Biography is an important biography by Michael Holroyd, portraying the extraordinary life of Lytton Strachey, who is also a biographer, in detail. Based on reading the text of Lytton Strachey: The New Biography, this paper analyzes Lytton Strachey’s most distinct character - rebel combined with the social background and the theory of “the New Biography” in three aspects. First, Strachey’s rebellious character in his daily life is analyzed. His beating falsetto, ironic tone and ambiguous silence make him mysterious; his unique dressing style makes him different in the Victorian Age when people tended to wear similar clothes with others in dark suits; and at this time people were all optimistic because of their powerful country while Strachey was always surrounded by a mysterious pessimistic air. Second, Strachey’s view of love is analyzed. He had a strong tendency of homosexual and most of his lovers in his life were males. While, in the Victorian Age, homosexual was illegal. Under the pressure of morality and law, Strachey still followed his heart and fell in love with his boys. His life interprets what love really is — his love is a kind of humanistic love, rather than simple lust. Third, this paper analyzes Strachey’s feminist and religious view. He was one of the supporters and participants of the feminist movement in the 19th century. In the society which was dominated by males, Strachey realized that human are born equally. Therefore, he started to fight for the females’ rights. In addition, in order to think independently, Strachey did not follow the crowds blindly to believe in God.

  19. A sample theory-based logic model to improve program development, implementation, and sustainability of Farm to School programs. (United States)

    Ratcliffe, Michelle M


    Farm to School programs hold promise to address childhood obesity. These programs may increase students’ access to healthier foods, increase students’ knowledge of and desire to eat these foods, and increase their consumption of them. Implementing Farm to School programs requires the involvement of multiple people, including nutrition services, educators, and food producers. Because these groups have not traditionally worked together and each has different goals, it is important to demonstrate how Farm to School programs that are designed to decrease childhood obesity may also address others’ objectives, such as academic achievement and economic development. A logic model is an effective tool to help articulate a shared vision for how Farm to School programs may work to accomplish multiple goals. Furthermore, there is evidence that programs based on theory are more likely to be effective at changing individuals’ behaviors. Logic models based on theory may help to explain how a program works, aid in efficient and sustained implementation, and support the development of a coherent evaluation plan. This article presents a sample theory-based logic model for Farm to School programs. The presented logic model is informed by the polytheoretical model for food and garden-based education in school settings (PMFGBE). The logic model has been applied to multiple settings, including Farm to School program development and evaluation in urban and rural school districts. This article also includes a brief discussion on the development of the PMFGBE, a detailed explanation of how Farm to School programs may enhance the curricular, physical, and social learning environments of schools, and suggestions for the applicability of the logic model for practitioners, researchers, and policy makers.

  20. Optimizing Biorefinery Design and Operations via Linear Programming Models

    Energy Technology Data Exchange (ETDEWEB)

    Talmadge, Michael; Batan, Liaw; Lamers, Patrick; Hartley, Damon; Biddy, Mary; Tao, Ling; Tan, Eric


    The ability to assess and optimize economics of biomass resource utilization for the production of fuels, chemicals and power is essential for the ultimate success of a bioenergy industry. The team of authors, consisting of members from the National Renewable Energy Laboratory (NREL) and the Idaho National Laboratory (INL), has developed simple biorefinery linear programming (LP) models to enable the optimization of theoretical or existing biorefineries. The goal of this analysis is to demonstrate how such models can benefit the developing biorefining industry. It focuses on a theoretical multi-pathway, thermochemical biorefinery configuration and demonstrates how the biorefinery can use LP models for operations planning and optimization in comparable ways to the petroleum refining industry. Using LP modeling tools developed under U.S. Department of Energy's Bioenergy Technologies Office (DOE-BETO) funded efforts, the authors investigate optimization challenges for the theoretical biorefineries such as (1) optimal feedstock slate based on available biomass and prices, (2) breakeven price analysis for available feedstocks, (3) impact analysis for changes in feedstock costs and product prices, (4) optimal biorefinery operations during unit shutdowns / turnarounds, and (5) incentives for increased processing capacity. These biorefinery examples are comparable to crude oil purchasing and operational optimization studies that petroleum refiners perform routinely using LPs and other optimization models. It is important to note that the analyses presented in this article are strictly theoretical and they are not based on current energy market prices. The pricing structure assigned for this demonstrative analysis is consistent with $4 per gallon gasoline, which clearly assumes an economic environment that would favor the construction and operation of biorefineries. The analysis approach and examples provide valuable insights into the usefulness of analysis tools for

    Full Text Available Valdosta State University and the Valdosta City Schools (Valdosta, GA partnered in 2008 to form the Valdosta Early College Academy (VECA. VECA epitomizes the early college concept of (a admitting underperforming students with multiple risk factors for dropping out of school (e.g., low socioeconomic status, minority, and first-generation high school or college and (b providing college level dual enrollment courses. VECA is very different than nearly every other early college school in the nation. Most (85% of the 200 early colleges currently operating in the United States begin with students in the 9th grade. Nearly all of the remaining early colleges begin with 7th grade; only a few are 6–12-grade schools. VECA targets two primary priorities, (a innovations that complement the implementation of higher standards and high-quality assessments and (b innovations that support college access and success. The primary purpose of this paper is to chronicle the genesis and development of VECA. This program is very successful, replete with research opportunities, and represents a model early college program. We plan to continue to grow VECA to ultimately include grades six through twelve and to research that growth and development.

  4. A Tool for Performance Modeling of Parallel Programs

    Directory of Open Access Journals (Sweden)

    J.A. González


    Full Text Available Current performance prediction analytical models try to characterize the performance behavior of actual machines through a small set of parameters. In practice, substantial deviations are observed. These differences are due to factors as memory hierarchies or network latency. A natural approach is to associate a different proportionality constant with each basic block, and analogously, to associate different latencies and bandwidths with each "communication block". Unfortunately, to use this approach implies that the evaluation of parameters must be done for each algorithm. This is a heavy task, implying experiment design, timing, statistics, pattern recognition and multi-parameter fitting algorithms. Software support is required. We present a compiler that takes as source a C program annotated with complexity formulas and produces as output an instrumented code. The trace files obtained from the execution of the resulting code are analyzed with an interactive interpreter, giving us, among other information, the values of those parameters.

  5. A Model Program for Translational Medicine in Epilepsy Genetics (United States)

    Smith, Lacey A.; Ullmann, Jeremy F. P.; Olson, Heather E.; El Achkar, Christelle M.; Truglio, Gessica; Kelly, McKenna; Rosen-Sheidley, Beth; Poduri, Annapurna


    Recent technological advances in gene sequencing have led to a rapid increase in gene discovery in epilepsy. However, the ability to assess pathogenicity of variants, provide functional analysis, and develop targeted therapies has not kept pace with rapid advances in sequencing technology. Thus, although clinical genetic testing may lead to a specific molecular diagnosis for some patients, test results often lead to more questions than answers. As the field begins to focus on therapeutic applications of genetic diagnoses using precision medicine, developing processes that offer more than equivocal test results is essential. The success of precision medicine in epilepsy relies on establishing a correct genetic diagnosis, analyzing functional consequences of genetic variants, screening potential therapeutics in the preclinical laboratory setting, and initiating targeted therapy trials for patients. We describe the structure of a comprehensive, pediatric Epilepsy Genetics Program that can serve as a model for translational medicine in epilepsy. PMID:28056630

    McElveen, John T; Blackburn, Erin L; Green, J Douglas; McLear, Patrick W; Thimsen, Donald J; Wilson, Blake S


    Evaluate the effectiveness of remote programming for cochlear implants. Retrospective review of the cochlear implant performance for patients who had undergone mapping and programming of their cochlear implant via remote connection through the Internet. Postoperative Hearing in Noise Test and Consonant/Nucleus/Consonant word scores for 7 patients who had undergone remote mapping and programming of their cochlear implant were compared with the mean scores of 7 patients who had been programmed by the same audiologist over a 12-month period. Times required for remote and direct programming were also compared. The quality of the Internet connection was assessed using standardized measures. Remote programming was performed via a virtual private network with a separate software program used for video and audio linkage. All 7 patients were programmed successfully via remote connectivity. No untoward patient experiences were encountered. No statistically significant differences could be found in comparing postoperative Hearing in Noise Test and Consonant/Nucleus/Consonant word scores for patients who had undergone remote programming versus a similar group of patients who had their cochlear implant programmed directly. Remote programming did not require a significantly longer programming time for the audiologist with these 7 patients. Remote programming of a cochlear implant can be performed safely without any deterioration in the quality of the programming. This ability to remotely program cochlear implant patients gives the potential to extend cochlear implantation to underserved areas in the United States and elsewhere.

  10. Linear programming model can explain respiration of fermentation products.

    Directory of Open Access Journals (Sweden)

    Philip Möller

    Full Text Available Many differentiated cells rely primarily on mitochondrial oxidative phosphorylation for generating energy in the form of ATP needed for cellular metabolism. In contrast most tumor cells instead rely on aerobic glycolysis leading to lactate to about the same extent as on respiration. Warburg found that cancer cells to support oxidative phosphorylation, tend to ferment glucose or other energy source into lactate even in the presence of sufficient oxygen, which is an inefficient way to generate ATP. This effect also occurs in striated muscle cells, activated lymphocytes and microglia, endothelial cells and several mammalian cell types, a phenomenon termed the "Warburg effect". The effect is paradoxical at first glance because the ATP production rate of aerobic glycolysis is much slower than that of respiration and the energy demands are better to be met by pure oxidative phosphorylation. We tackle this question by building a minimal model including three combined reactions. The new aspect in extension to earlier models is that we take into account the possible uptake and oxidation of the fermentation products. We examine the case where the cell can allocate protein on several enzymes in a varying distribution and model this by a linear programming problem in which the objective is to maximize the ATP production rate under different combinations of constraints on enzymes. Depending on the cost of reactions and limitation of the substrates, this leads to pure respiration, pure fermentation, and a mixture of respiration and fermentation. The model predicts that fermentation products are only oxidized when glucose is scarce or its uptake is severely limited.

    Full Text Available Mário Cláudio’s novel, Tiago Veiga, uma biografia (2011, is a long and uni­que biography that follows the path of former biographies. Three distinct forms of memory writing can be detached here among other singularities. Firstly, there is the idea of a challenging and well aware heteronimic pro­cess that is focused in the misterious life of Tiago Veiga. Secondly, there is the biographic portrait that is constructed within the observance of the gender codes and beholds a wide scope of intertextual rememberances. Finally, this becomes a unique crytical biography of Portugal during one century, because it recreates the cosmopolitan life of an unknown character born in 1910.

The genesis of Armorican arrowheads are in all likelihood explained by a climate of increasing social competition, which express itself in Brittany by an individualization of burial rites, a development of metalworking and a reorganization of territories.In this article, we will stress on raw materials selection, technology and know-how, as well as use-wear analyses. All these approaches will help us to trace the biographies of the Armorican arrowheads.

  14. Fish Processed Production Planning Using Integer Stochastic Programming Model (United States)

    Firmansyah, Mawengkang, Herman


    Fish and its processed products are the most affordable source of animal protein in the diet of most people in Indonesia. The goal in production planning is to meet customer demand over a fixed time horizon divided into planning periods by optimizing the trade-off between economic objectives such as production cost and customer satisfaction level. The major decisions are production and inventory levels for each product and the number of workforce in each planning period. In this paper we consider the management of small scale traditional business at North Sumatera Province which performs processing fish into several local seafood products. The inherent uncertainty of data (e.g. demand, fish availability), together with the sequential evolution of data over time leads the production planning problem to a nonlinear mixed-integer stochastic programming model. We use scenario generation based approach and feasible neighborhood search for solving the model. The results which show the amount of each fish processed product and the number of workforce needed in each horizon planning are presented.

  16. The Component Model of Infrastructure: A Practical Approach to Understanding Public Health Program Infrastructure (United States)

    Snyder, Kimberly; Rieker, Patricia P.


    Functioning program infrastructure is necessary for achieving public health outcomes. It is what supports program capacity, implementation, and sustainability. The public health program infrastructure model presented in this article is grounded in data from a broader evaluation of 18 state tobacco control programs and previous work. The newly developed Component Model of Infrastructure (CMI) addresses the limitations of a previous model and contains 5 core components (multilevel leadership, managed resources, engaged data, responsive plans and planning, networked partnerships) and 3 supporting components (strategic understanding, operations, contextual influences). The CMI is a practical, implementation-focused model applicable across public health programs, enabling linkages to capacity, sustainability, and outcome measurement. PMID:24922125

  17. Lytton Strachey : l’historien intime de deux reines Lytton Strachey’s Intimate Biographies of Two Queens

    Directory of Open Access Journals (Sweden)

    Jeannine Hayat


    Full Text Available The British writer Lytton Strachey (1880-1932 wrote biographies of the two most eminent Queens of England: Queen Victoria (1921 and Elizabeth and Essex (1928. The two books made him a very famous historian. However, he would personally have preferred to be admired for his poetry or his plays, for he was a very gifted literary author. Nevertheless many of Strachey’s readers have appreciated his conception of biography, as a means of personal confession while studying the destiny of a public figure. Indeed the Stracheyan way of life, free from Victorian moral standards and guided by the rules of the Bloomsbury group, inspired his story of Victoria and Elizabeth. Both Queens at the end of their lives and at the height of their power carried on strange love affairs: Victoria with her Scottish gillie and Elizabeth with the Earl of Essex, thirty years her younger. In fact, both romances subtly reflect Strachey’s own love affairs. He was himself engaged in a kind of common life with Dora Carrington— the painter, thirteen years younger than him, with whom he was not sexually involved— while he engaged in numerous homosexual love affairs.

  18. The biography of scientists as a means of communicating science: analogies concerning a hermeneutic or empirical problem

    Directory of Open Access Journals (Sweden)

    Maria Francisca Carneiro


    Full Text Available Sometimes scientists live real dramas or undergo social and psychological conflicts which have a positive or negative influence on the development and recognition of their research, discoveries and inventions in society, including the way they are recorded in history. This being so, the question is: to what extent can science be communicated to the public at large by the use of scientists' biographies as a motivational strategy? The controversy arises from the fact that usual (classical science has traditionally argued for the separation (or de-linking of the research (the object from the researcher (the subject.Thus, if the above-mentioned motivational strategy is used in scientific communication, it could break a dominant methodological trend and consequently lead to a questioning of the myth of axiological neutrality in science. The communication of science by means of scientists' biographies could be useful for reaching a specific public, more directed towards emotional aspects, thereby awakening its interest in science, even amid cultural differences and in environments where interest in science and its utility is lacking. It could also reveal human aspects of the everyday life of scientists, bringing them closer to the public at large, which would contribute to the dissemination of science and knowledge.

  20. An abort-aware model of transactional programming


    Etessami, Kousha; Godefroid, Patrice


    There has been a lot of recent research on transaction-based concurrent programming, aimed at offering an easier concurrent programming paradigm that enables programmers to better exploit the parallelism of modern multi-processor machines, such as multi-core microprocessors. We introduce Transactional State Machines (TSMs) as an abstract finite-datamodel of transactional shared-memory concurrent programs. TSMs are a variant of concurrent boolean programs (or concurrent extended recursive stat...

  1. The Father Friendly Initiative within Families: Using a logic model to develop program theory for a father support program. (United States)

    Gervais, Christine; de Montigny, Francine; Lacharité, Carl; Dubeau, Diane


    The transition to fatherhood, with its numerous challenges, has been well documented. Likewise, fathers' relationships with health and social services have also begun to be explored. Yet despite the problems fathers experience in interactions with healthcare services, few programs have been developed for them. To explain this, some authors point to the difficulty practitioners encounter in developing and structuring the theory of programs they are trying to create to promote and support father involvement (Savaya, R., & Waysman, M. (2005). Administration in Social Work, 29(2), 85), even when such theory is key to a program's effectiveness (Chen, H.-T. (2005). Practical program evaluation. Thousand Oaks, CA: Sage Publications). The objective of the present paper is to present a tool, the logic model, to bridge this gap and to equip practitioners for structuring program theory. This paper addresses two questions: (1) What would be a useful instrument for structuring the development of program theory in interventions for fathers? (2) How would the concepts of a father involvement program best be organized? The case of the Father Friendly Initiative within Families (FFIF) program is used to present and illustrate six simple steps for developing a logic model that are based on program theory and demonstrate its relevance.

  2. Development of a Program Logic Model and Evaluation Plan for a Participatory Ergonomics Intervention in Construction (United States)

    Jaegers, Lisa; Dale, Ann Marie; Weaver, Nancy; Buchholz, Bryan; Welch, Laura; Evanoff, Bradley


    Background Intervention studies in participatory ergonomics (PE) are often difficult to interpret due to limited descriptions of program planning and evaluation. Methods In an ongoing PE program with floor layers, we developed a logic model to describe our program plan, and process and summative evaluations designed to describe the efficacy of the program. Results The logic model was a useful tool for describing the program elements and subsequent modifications. The process evaluation measured how well the program was delivered as intended, and revealed the need for program modifications. The summative evaluation provided early measures of the efficacy of the program as delivered. Conclusions Inadequate information on program delivery may lead to erroneous conclusions about intervention efficacy due to Type III error. A logic model guided the delivery and evaluation of our intervention and provides useful information to aid interpretation of results. PMID:24006097

  4. Education Model Program on Water-Energy Research: A New STEM Graduate Program from Development through Evaluation (United States)

    McCay, D.; Fiorenza, P.; Lautz, L.


    More than half of Ph.D. scientists and engineers find employment in non-academic sectors. Recognizing the range of career options for graduate degree holders and the need to align graduate education with the expectations of prospective employers, the National Science Foundation (NSF) created the NSF Research Traineeship (NRT) program. To date, over 100 NRT programs have been funded. As these programs are implemented, it is important to assess their progress, successes, and challenges. This presentation describes the ongoing evaluation of one NRT program, "Education Model Program on Water-Energy Research" (or EMPOWER) at Syracuse University. Through seminars, mini-grants, professional development activities, field courses, internship opportunities, and coursework, EMPOWER's goal is to equip students with the skills needed for the range of career options in water and energy. In collaboration with an external evaluator, EMPOWER is examining the fidelity of the program to proposed goals, providing feedback to inform project improvement (formative assessment) and assessing the effectiveness of achieving program goals (summative assessment). Using a convergent parallel mixed method design, qualitative and quantitative data were collected to develop a full assessment of the first year of the program. Evaluation findings have resulted in several positive changes to the program. For example, EMPOWER students perceive themselves to have high technical skills, but the data show that the students do not believe that they have a strong professional network. Based on those findings, EMPOWER offered several professional development events focused on building one's professional network. Preliminary findings have enabled the EMPOWER leadership team to make informed decisions about the ways the program elements can be redesigned to better meet student needs, about how to the make the program more effective, and determine the program elements that may be sustained beyond the funding

  7. EvoBuild: A Quickstart Toolkit for Programming Agent-Based Models of Evolutionary Processes (United States)

    Wagh, Aditi; Wilensky, Uri


    Extensive research has shown that one of the benefits of programming to learn about scientific phenomena is that it facilitates learning about mechanisms underlying the phenomenon. However, using programming activities in classrooms is associated with costs such as requiring additional time to learn to program or students needing prior experience with programming. This paper presents a class of programming environments that we call quickstart: Environments with a negligible threshold for entry into programming and a modest ceiling. We posit that such environments can provide benefits of programming for learning without incurring associated costs for novice programmers. To make this claim, we present a design-based research study conducted to compare programming models of evolutionary processes with a quickstart toolkit with exploring pre-built models of the same processes. The study was conducted in six seventh grade science classes in two schools. Students in the programming condition used EvoBuild, a quickstart toolkit for programming agent-based models of evolutionary processes, to build their NetLogo models. Students in the exploration condition used pre-built NetLogo models. We demonstrate that although students came from a range of academic backgrounds without prior programming experience, and all students spent the same number of class periods on the activities including the time students took to learn programming in this environment, EvoBuild students showed greater learning about evolutionary mechanisms. We discuss the implications of this work for design research on programming environments in K-12 science education.

  9. Risk assessment to an integrated planning model for UST programs

    International Nuclear Information System (INIS)

    Ferguson, K.W.


    The US Postal Service maintains the largest civilian fleet in the United States totaling approximately 180,000 vehicles. To support the fleets daily energy requirements, the Postal Service also operates one of the largest networks of underground storage tanks nearly 7,500 nationwide. A program to apply risk assessment to planning, budget development and other management actions was implemented during September, 1989. Working closely with a consultant, the postal service developed regulatory and environmental risk criteria and weighting factors for a ranking model. The primary objective was to identify relative risks for each underground tank at individual facilities. Relative risks at each facility were determined central to prioritizing scheduled improvements to the tank network. The survey was conducted on 302 underground tanks in the Northeast Region of the US. An environmental and regulatory risk score was computed for each UST. By ranking the tanks according to their risk score, tanks were classified into management action categories including, but the limited to, underground tank testing, retrofit, repair, replacement and closure

  10. A program for verification of phylogenetic network models. (United States)

    Gunawan, Andreas D M; Lu, Bingxin; Zhang, Louxin


    Genetic material is transferred in a non-reproductive manner across species more frequently than commonly thought, particularly in the bacteria kingdom. On one hand, extant genomes are thus more properly considered as a fusion product of both reproductive and non-reproductive genetic transfers. This has motivated researchers to adopt phylogenetic networks to study genome evolution. On the other hand, a gene's evolution is usually tree-like and has been studied for over half a century. Accordingly, the relationships between phylogenetic trees and networks are the basis for the reconstruction and verification of phylogenetic networks. One important problem in verifying a network model is determining whether or not certain existing phylogenetic trees are displayed in a phylogenetic network. This problem is formally called the tree containment problem. It is NP-complete even for binary phylogenetic networks. We design an exponential time but efficient method for determining whether or not a phylogenetic tree is displayed in an arbitrary phylogenetic network. It is developed on the basis of the so-called reticulation-visible property of phylogenetic networks.

  12. Devil is in the details: Using logic models to investigate program process. (United States)

    Peyton, David J; Scicchitano, Michael


    Theory-based logic models are commonly developed as part of requirements for grant funding. As a tool to communicate complex social programs, theory based logic models are an effective visual communication. However, after initial development, theory based logic models are often abandoned and remain in their initial form despite changes in the program process. This paper examines the potential benefits of committing time and resources to revising the initial theory driven logic model and developing detailed logic models that describe key activities to accurately reflect the program and assist in effective program management. The authors use a funded special education teacher preparation program to exemplify the utility of drill down logic models. The paper concludes with lessons learned from the iterative revision process and suggests how the process can lead to more flexible and calibrated program management. Copyright © 2017 Elsevier Ltd.

  14. Thermal models of buildings. Determination of temperatures, heating and cooling loads. Theories, models and computer programs

    Energy Technology Data Exchange (ETDEWEB)

    Kaellblad, K.


    The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meet the authorities requirements given in building codes. All these situations require good calculation methods. The main purpose of this report is to present the authors work with problems related to thermal models and calculation methods for determination of temperatures and heating or cooling loads in buildings. Thus the major part of the report deals with treatment of solar radiation in glazing systems, shading of solar and sky radiation and the computer program JULOTTA used to simulate the thermal behavior of rooms and buildings. Other parts of thermal models of buildings are more briefly discussed and included in order to give an overview of existing problems and available solutions. A brief presentation of how thermal models can be built up is also given and it is a hope that the report can be useful as an introduction to this part of building physics as well as during development of calculation methods and computer programs. The report may also serve as a help for the users of energy related programs. Independent of which method or program a user choose to work with it is his or her own responsibility to understand the limits of the tool, else wrong conclusions may be drawn from the results 52 refs, 22 figs, 4 tabs

The program texts are provided.

  18. Prenatal programming of sexual partner preference: the ram model. (United States)

    Roselli, C E; Stormshak, F


    In our laboratory, the domestic ram is used as an experimental model to study the early programming of neural mechanisms underlying same-sex partner preference. This interest developed from the observation that approximately 8% of domestic rams are sexually attracted to other rams (male-oriented) in contrast to the majority of rams that are attracted to oestrous ewes (female-oriented). One prominent feature of sexual differentiation in many species is the presence of a sexually dimorphic nucleus (SDN) in the preoptic/anterior hypothalamus that is larger in males than in females. Lesion studies in rats and ferrets implicate the SDN in the expression of sexual preferences. We discovered an ovine SDN (oSDN) in the preoptic/anterior hypothalamus that is smaller in male- than in female-oriented rams and similar in size to the oSDN of ewes. Neurones of the oSDN show abundant aromatase expression that is also reduced in male-oriented compared to female-oriented rams. This observation suggests that sexual partner preferences are neurologically hard-wired and could be influenced by hormones. Aromatase-containing neurones constitute a nascent oSDN as early as day 60 of gestation, which becomes sexually dimorphic by day 135 of gestation when it is two-fold larger in males than in females. Exposure of fetal female lambs to exogenous testosterone from days 30-90 of gestation resulted in a masculinised oSDN. These data demonstrate that the oSDN develops prenatally and may influence adult sexual preferences. Surprisingly, inhibition of aromatase activity in the brain of ram foetuses during the critical period did not interfere with defeminisation of adult sexual partner preference or oSDN volume. These results fail to support an essential role for neural aromatase in the sexual differentiation of sheep brain and behaviour. Thus, we propose that oSDN morphology and male-typical partner preferences may instead be programmed through an androgen receptor mechanism not involving

  19. The Development Study of a Medical Ethics Education Program by Using Simple ISD Model. (United States)

    Kim, Young Jon; Yoo, Hyoo Hyun; Joo, Chan Uhng


    Simple instructional systems design (ISD) model is based on a fast development, usability test, and continuos feedback, which are necessary for educational program development in medical school. This study aims to figure out the usability of Simple ISD model for a medical ethics education program by describing a developmental details of each phase and its evaluation results. Research has been conducted in two steps. First, while researchers participated in the program development by using Simple ISD model, we collected empirical data of each development activities. Second, the developed program was evaluated by students' web-based usability test, a 8-students' focus group interview and 5 faculty members' individual interviews in 4 domains; learning contents, instructional methods and strategies, achievement evaluation, and self-evaluation. Following the circular process of analysis, design, development, and usability test of Simple ISD model, a 10-week medical ethics program covering 9 instructional topics was developed. The average points of response on the developed medical ethics program in 2008 and 2009 are increased from 3.96 to 4.59 and 4.41, respectively. The prospects and limitations of the program are discussed. From a development study of the medical ethics program by using Simple ISD model, we could implement a more usable medical ethics program, and found 4 different usability of the Simple ISD model; the rapid development of educational program, program improvement by continuous feedback, faculty members' engagement in instructional design, and professional development of the faculty members.

    Directory of Open Access Journals (Sweden)

    Susanne Bressan


    Full Text Available How do extraordinary experiences, especially during childhood and adolescence, affect political attitudes? Most studies focusing on political movements only implicitly address the connection between biographical experiences and political attitudes. Moreover, a detailed understanding of these impacts often remains merely hypothetical. Biographical studies increasingly address the relationship between politics and biography through empirical and hermeneutic approaches. For his doctoral thesis, Dirk MICHEL conducts autobiographical narrative interviews with 20 Jewish Israelis. Based on their extraordinary biographical experiences, MICHEL categorized the interviewees into two groups—the "German Zionists" and the "German Holocaust survivors." He then conducts semi-structured interviews with each of the participants with the aim of analyzing their political attitudes. However, the conceptual categorization of the interviewees, the empirical investigation of the research question and the subsequent analysis all challenge the underpinning theoretical and methodological concepts of the study.

    Larsen, Per; Karlsson, Sven; Madsen, Jan


    Modern computers often use multi-core architectures, cov- ering clusters of homogeneous cores for high performance computing,to heterogeneous architectures typically found in embedded systems. To efficiently program such architectures, it is important to be able to par- tition and map programs onto...... the cores of the architecture. We believe that communication patterns need to become explicit in the source code to make it easier to analyze and partition parallel programs. Extraction of these patterns are difficult to automate due to limitations in compiler techniques when determining the effects...... of pointers.

We present a dependency directive, expressing the input and output relation between program parts and pointers to shared data, as well...

  10. Updating Linear Schedules with Lowest Cost: a Linear Programming Model (United States)

    Biruk, Sławomir; Jaśkowski, Piotr; Czarnigowska, Agata


    Many civil engineering projects involve sets of tasks repeated in a predefined sequence in a number of work areas along a particular route. A useful graphical representation of schedules of such projects is time-distance diagrams that clearly show what process is conducted at a particular point of time and in particular location. With repetitive tasks, the quality of project performance is conditioned by the ability of the planner to optimize workflow by synchronizing the works and resources, which usually means that resources are planned to be continuously utilized. However, construction processes are prone to risks, and a fully synchronized schedule may expire if a disturbance (bad weather, machine failure etc.) affects even one task. In such cases, works need to be rescheduled, and another optimal schedule should be built for the changed circumstances. This typically means that, to meet the fixed completion date, durations of operations have to be reduced. A number of measures are possible to achieve such reduction: working overtime, employing more resources or relocating resources from less to more critical tasks, but they all come at a considerable cost and affect the whole project. The paper investigates the problem of selecting the measures that reduce durations of tasks of a linear project so that the cost of these measures is kept to the minimum and proposes an algorithm that could be applied to find optimal solutions as the need to reschedule arises. Considering that civil engineering projects, such as road building, usually involve less process types than construction projects, the complexity of scheduling problems is lower, and precise optimization algorithms can be applied. Therefore, the authors put forward a linear programming model of the problem and illustrate its principle of operation with an example.

    This report describes the development and testing of the Kansas Technology Transfer Model (KTTM) which is to be utilized as a regional model for the development of other technology transfer programs for independent operators throughout oil-producing regions in the US. It describes the linkage of the regional model with a proposed national technology transfer plan, an evaluation technique for improving and assessing the model, and the methodology which makes it adaptable on a regional basis. The report also describes management concepts helpful in managing a technology transfer program. The original Tertiary Oil Recovery Project (TORP) activities, upon which the KTTM is based, were developed and tested for Kansas and have proved to be effective in assisting independent operators in utilizing technology. Through joint activities of TORP and the Kansas Geological Survey (KGS), the KTTM was developed and documented for application in other oil-producing regions. During the course of developing this model, twelve documents describing the implementation of the KTTM were developed as deliverables to DOE. These include: (1) a problem identification (PI) manual describing the format and results of six PI workshops conducted in different areas of Kansas, (2) three technology workshop participant manuals on advanced waterflooding, reservoir description, and personal computer applications, (3) three technology workshop instructor manuals which provides instructor material for all three workshops, (4) three technologies were documented as demonstration projects which included reservoir management, permeability modification, and utilization of a liquid-level acoustic measuring device, (5) a bibliography of all literature utilized in the documents, and (6) a document which describes the KTTM.

  19. LDA-Based Unified Topic Modeling for Similar TV User Grouping and TV Program Recommendation. (United States)

    Pyo, Shinjee; Kim, Eunhui; Kim, Munchurl


    Social TV is a social media service via TV and social networks through which TV users exchange their experiences about TV programs that they are viewing. For social TV service, two technical aspects are envisioned: grouping of similar TV users to create social TV communities and recommending TV programs based on group and personal interests for personalizing TV. In this paper, we propose a unified topic model based on grouping of similar TV users and recommending TV programs as a social TV service. The proposed unified topic model employs two latent Dirichlet allocation (LDA) models. One is a topic model of TV users, and the other is a topic model of the description words for viewed TV programs. The two LDA models are then integrated via a topic proportion parameter for TV programs, which enforces the grouping of similar TV users and associated description words for watched TV programs at the same time in a unified topic modeling framework. The unified model identifies the semantic relation between TV user groups and TV program description word groups so that more meaningful TV program recommendations can be made. The unified topic model also overcomes an item ramp-up problem such that new TV programs can be reliably recommended to TV users. Furthermore, from the topic model of TV users, TV users with similar tastes can be grouped as topics, which can then be recommended as social TV communities. To verify our proposed method of unified topic-modeling-based TV user grouping and TV program recommendation for social TV services, in our experiments, we used real TV viewing history data and electronic program guide data from a seven-month period collected by a TV poll agency. The experimental results show that the proposed unified topic model yields an average 81.4% precision for 50 topics in TV program recommendation and its performance is an average of 6.5% higher than that of the topic model of TV users only. For TV user prediction with new TV programs, the average

  20. An OpenACC-Based Unified Programming Model for Multi-accelerator Systems

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Jungwon [ORNL; Lee, Seyong [ORNL; Vetter, Jeffrey S [ORNL


    This paper proposes a novel SPMD programming model of OpenACC. Our model integrates the different granularities of parallelism from vector-level parallelism to node-level parallelism into a single, unified model based on OpenACC. It allows programmers to write programs for multiple accelerators using a uniform programming model whether they are in shared or distributed memory systems. We implement a prototype of our model and evaluate its performance with a GPU-based supercomputer using three benchmark applications.

  1. On the Terminological Mistake in the Biography of the Astrakhan Cossack Regiment Commander, Major General P.S. Popov

    Directory of Open Access Journals (Sweden)

    Astafyev Evgeniy V.


    Full Text Available On the basis of authentic documents of the late 18th – early 19th centuries, stored in federal and regional archives of Russia, as well as published materials, the article analyzes the reasons of the terminological mistake made in the biography of commander of Astrakhan’s Cossack regiment, major general P.S. Popov, which had been reproduced in the scientific works for longer than 100 years. So well known person in the Lower Volga region, P.S. Popov was purposefully chosen as an object of historical research. His biography is not typical for the people of provincial hereditary Russian nobility of this period, Astrakhan and Saratov’s nobility in this case, where, although rather conventionally, he was linked for a long time in the historical literature. Thanks to the current research, it was determined that P.S. Popov was born in Walachia, evidently not very rich noble family. For a long time he served in Bug Cossack regiment, where got promoted from Arnaut captain to officer rank. He took part in many campaigns of Russian-Turkish war, was repeatedly injured, and distinguished himself during the capture of the fortresses Ochakov and Ismail. P.S. Popov was awarded the order of St. John of Jerusalem, and golden mark for capture of Ismail. P.S. Popov was married to a daughter of Astrakhan priest, and had seven sons and daughters in this spousal. Already serving in Astrakhan province, he purchased a seigneury for himself and descendants in Tsaritsyn district of the Saratov province. His descendants settled in the Lower Volga region, kept the seigneury in possession, served in military and civil services.

    International Nuclear Information System (INIS)

    Domingos, Roberto P.; Schirru, Roberto; Martinez, Aquilino S.


    This work presents a Genetic Programming paradigm and a nuclear application. A field of Artificial Intelligence, based on the concepts of Species Evolution and Natural Selection, can be understood as a self-programming process where the computer is the main agent responsible for the discovery of a program able to solve a given problem. In the present case, the problem was to find a mathematical expression in symbolic form, able to express the existent relation between equivalent ratio of a fuel cell, the enrichment of fuel elements and the multiplication factor. Such expression would avoid repeatedly reactor physics codes execution for core optimization. The results were compared with those obtained by different techniques such as Neural Networks and Linear Multiple Regression. Genetic Programming has shown to present a performance as good as, and under some features superior to Neural Network and Linear Multiple Regression. (author). 10 refs., 8 figs., 1 tabs

    Lusk, E.L.; Pieper, S.C.; Butler, R.M.


    This is the story of a simple programming model, its implementation for extreme computing, and a breakthrough in nuclear physics. A critical issue for the future of high-performance computing is the programming model to use on next-generation architectures. Described here is a promising approach: program very large machines by combining a simplified programming model with a scalable library implementation. The presentation takes the form of a case study in nuclear physics. The chosen application addresses fundamental issues in the origins of our Universe, while the library developed to enable this application on the largest computers may have applications beyond this one.

    Full Text Available MATLAB-programs of some discrete random event has been developed and intended (1 as an exercise at the study of Algorithmization and Programming Course, and (2 for carrying out some "experiments" by lecturing the Course of Probability and Statistics Theory, or at its self-study by students. The programs allows to do several probabilistic experiments in a necessary amount M, using the random number generator, to count up frequency of "favorable events" appearance and compare it to theoretical probability. This displays the Law of large numbers, i.e. approaching experimental results to theory with unlimited increase of М. The work, however, lies not only in this pragmatic result. It should encourage students to study problems of Probability Theory by means of creation appropriate computer codes. The most easy and quick way to this leads to MATLAB-environment. That is why the paper suggests principles of programming in it along with creation of graphical user interface (GUI.

    We describe new capabilities for modeling MPEC problems within the Pyomo modeling software. These capabilities include new modeling components that represent complementar- ity conditions, modeling transformations for re-expressing models with complementarity con- ditions in other forms, and meta-solvers that apply transformations and numeric optimization solvers to optimize MPEC problems. We illustrate the breadth of Pyomo's modeling capabil- ities for MPEC problems, and we describe how Pyomo's meta-solvers can perform local and global optimization of MPEC problems.

  14. INTERLINE, a railroad routing model: program description and user's manual

    International Nuclear Information System (INIS)

    Peterson, B.E.


    INTERLINE is an interactive computer program that finds likely routes for shipments over the US railroad system. It is based on a shortest path algorithm modified both to reflect the nature of railroad company operations and to accommodate computer resource limitations in dealing with a large transportation network. The first section of the report discusses the nature of railroad operations and routing practices in the United States, including the tendency to concentrate traffic on a limited number of mainlines, the competition for traffic by different companies operating in the same corridors, and the tendency of originating carriers to retain traffic on their systems before transferring it to terminating carriers. The theoretical foundation and operation of shortest path algorithms are described, as well as the techniques used to simulate actual operating practices within this framework. The second section is a user's guide that describes the program operation and data structures, program features, and user access. 11 refs., 11 figs

  15. Stochastic Fractional Programming Approach to a Mean and Variance Model of a Transportation Problem

    Directory of Open Access Journals (Sweden)

    V. Charles


    Full Text Available In this paper, we propose a stochastic programming model, which considers a ratio of two nonlinear functions and probabilistic constraints. In the former, only expected model has been proposed without caring variability in the model. On the other hand, in the variance model, the variability played a vital role without concerning its counterpart, namely, the expected model. Further, the expected model optimizes the ratio of two linear cost functions where as variance model optimize the ratio of two non-linear functions, that is, the stochastic nature in the denominator and numerator and considering expectation and variability as well leads to a non-linear fractional program. In this paper, a transportation model with stochastic fractional programming (SFP problem approach is proposed, which strikes the balance between previous models available in the literature.

  20. Uncertain and multi-objective programming models for crop planting structure optimization

    Directory of Open Access Journals (Sweden)

    Mo LI,Ping GUO,Liudong ZHANG,Chenglong ZHANG


    Full Text Available Crop planting structure optimization is a significant way to increase agricultural economic benefits and improve agricultural water management. The complexities of fluctuating stream conditions, varying economic profits, and uncertainties and errors in estimated modeling parameters, as well as the complexities among economic, social, natural resources and environmental aspects, have led to the necessity of developing optimization models for crop planting structure which consider uncertainty and multi-objectives elements. In this study, three single-objective programming models under uncertainty for crop planting structure optimization were developed, including an interval linear programming model, an inexact fuzzy chance-constrained programming (IFCCP model and an inexact fuzzy linear programming (IFLP model. Each of the three models takes grayness into account. Moreover, the IFCCP model considers fuzzy uncertainty of parameters/variables and stochastic characteristics of constraints, while the IFLP model takes into account the fuzzy uncertainty of both constraints and objective functions. To satisfy the sustainable development of crop planting structure planning, a fuzzy-optimization-theory-based fuzzy linear multi-objective programming model was developed, which is capable of reflecting both uncertainties and multi-objective. In addition, a multi-objective fractional programming model for crop structure optimization was also developed to quantitatively express the multi-objective in one optimization model with the numerator representing maximum economic benefits and the denominator representing minimum crop planting area allocation. These models better reflect actual situations, considering the uncertainties and multi-objectives of crop planting structure optimization systems. The five models developed were then applied to a real case study in Minqin County, north-west China. The advantages, the applicable conditions and the solution methods

  1. Modeling Activities in the Department of Energy’s Atmospheric Sciences Program

    Energy Technology Data Exchange (ETDEWEB)

    Fast, Jerome D.; Ghan, Steven J.; Schwartz, Stephen E.


    The Department of Energy's Atmospheric Science Program (ASP) conducts research pertinent to radiative forcing of climate change by atmospheric aerosols. The program consists of approximately 40 highly interactive peer-reviewed research projects that examine aerosol properties and processes and the evolution of aerosols in the atmosphere. Principal components of the program are instrument development, laboratory experiments, field studies, theoretical investigations, and modeling. The objectives of the Program are to 1) improve the understanding of aerosol processes associated with light scattering and absorption properties and interactions with clouds that affect Earth's radiative balance and to 2) develop model-based representations of these processes that enable the effects of aerosols on Earth's climate system to be properly represented in global-scale numerical climate models. Although only a few of the research projects within ASP are explicitly identified as primarily modeling activities, modeling actually comprises a substantial component of a large fraction of ASP research projects. This document describes the modeling activities within the Program as a whole, the objectives and intended outcomes of these activities, and the linkages among the several modeling components and with global-scale modeling activities conducted under the support of the Department of Energy's Climate Sciences Program and other aerosol and climate research programs.

  2. Modelling and Formal Verification of Timing Aspects in Large PLC Programs

    CERN Document Server

    Fernandez Adiego, B; Blanco Vinuela, E; Tournier, J-C; Gonzalez Suarez, V M; Blech, J O


    One of the main obstacle that prevents model checking from being widely used in industrial control systems is the complexity of building formal models out of PLC programs, especially when timing aspects need to be integrated. This paper brings an answer to this obstacle by proposing a methodology to model and verify timing aspects of PLC programs. Two approaches are proposed to allow the users to balance the trade-off between the complexity of the model, i.e. its number of states, and the set of specifications possible to be verified. A tool supporting the methodology which allows to produce models for different model checkers directly from PLC programs has been developed. Verification of timing aspects for real-life PLC programs are presented in this paper using NuSMV.

    Sarela, Antti; Whittaker, Frank; Korhonen, Ilkka


    Cardiac rehabilitation programs are comprehensive life-style programs aimed at preventing recurrence of a cardiac event. However, the current programs have globally significantly low levels of uptake. Home-based model can be a viable alternative to hospital-based programs. We developed and analysed a service and business model for home based cardiac rehabilitation based on personal mentoring using mobile phones and web services. We analysed the different organizational and economical aspects of setting up and running the home based program and propose a potential business model for a sustainable and viable service. The model can be extended to management of other chronic conditions to enable transition from hospital and care centre based treatments to sustainable home-based care.

    Parallel programming is designed for the use of parallel computer systems for solving time-consuming problems that cannot be solved on a sequential computer in a reasonable time. These problems can be divided into two classes: 1. Processing large data arrays (including processing images and signals in real time)2. Simulation of complex physical processes and chemical reactions For each of these classes, prospective methods are designed for solving problems. For data processing, one of the most promising technologies is the use of artificial neural networks. Particles-in-cell method and cellular automata are very useful for simulation. Problems of scalability of parallel algorithms and the transfer of existing parallel programs to future parallel computers are very acute now. An important task is to optimize the use of the equipment (including the CPU cache) of parallel computers. Along with parallelizing information processing, it is essential to ensure the processing reliability by the relevant organization ...

  17. Keys to the House: Unlocking Residential Savings With Program Models for Home Energy Upgrades

    Energy Technology Data Exchange (ETDEWEB)

    Grevatt, Jim [Energy Futures Group (United States); Hoffman, Ian [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Hoffmeyer, Dale [US Department of Energy, Washington, DC (United States)


    After more than 40 years of effort, energy efficiency program administrators and associated contractors still find it challenging to penetrate the home retrofit market, especially at levels commensurate with state and federal goals for energy savings and emissions reductions. Residential retrofit programs further have not coalesced around a reliably successful model. They still vary in design, implementation and performance, and they remain among the more difficult and costly options for acquiring savings in the residential sector. If programs are to contribute fully to meeting resource and policy objectives, administrators need to understand what program elements are key to acquiring residential savings as cost effectively as possible. To that end, the U.S. Department of Energy (DOE) sponsored a comprehensive review and analysis of home energy upgrade programs with proven track records, focusing on those with robustly verified savings and constituting good examples for replication. The study team reviewed evaluations for the period 2010 to 2014 for 134 programs that are funded by customers of investor-owned utilities. All are programs that promote multi-measure retrofits or major system upgrades. We paid particular attention to useful design and implementation features, costs, and savings for nearly 30 programs with rigorous evaluations of performance. This meta-analysis describes program models and implementation strategies for (1) direct install retrofits; (2) heating, ventilating and air-conditioning (HVAC) replacement and early retirement; and (3) comprehensive, whole-home retrofits. We analyze costs and impacts of these program models, in terms of both energy savings and emissions avoided. These program models can be useful guides as states consider expanding their strategies for acquiring energy savings as a resource and for emissions reductions. We also discuss the challenges of using evaluations to create program models that can be confidently applied in

  19. A simulation model of IT risk on program trading (United States)

    Xia, Bingying; Jiang, Wenbao; Luo, Guangxuan


    The biggest difficulty for Program trading IT risk measures lies in the loss of data, in view of this situation, the current scholars approach is collecting court, network and other public media such as all kinds of accident of IT both at home and abroad for data collection, and the loss of IT risk quantitative analysis based on this database. However, the IT risk loss database established by this method can only fuzzy reflect the real situation and not for real to make fundamental explanation. In this paper, based on the study of the concept and steps of the MC simulation, we use computer simulation method, by using the MC simulation method in the "Program trading simulation system" developed by team to simulate the real programming trading and get the IT risk loss of data through its IT failure experiment, at the end of the article, on the effectiveness of the experimental data is verified. In this way, better overcome the deficiency of the traditional research method and solves the problem of lack of IT risk data in quantitative research. More empirically provides researchers with a set of simulation method are used to study the ideas and the process template.

    In 2001, the Norwegian Goat Health Service initiated the Healthier Goats program (HG), with the aim of eradicating caprine arthritis encephalitis, caseous lymphadenitis, and Johne's disease (caprine paratuberculosis) in Norwegian goat herds. The aim of the present study was to explore how control and eradication of the above-mentioned diseases by enrolling in HG affected milk yield by comparison with herds not enrolled in HG. Lactation curves were modeled using a multilevel cubic spline regression model where farm, goat, and lactation were included as random effect parameters. The data material contained 135,446 registrations of daily milk yield from 28,829 lactations in 43 herds. The multilevel cubic spline regression model was applied to 4 categories of data: enrolled early, control early, enrolled late, and control late. For enrolled herds, the early and late notations refer to the situation before and after enrolling in HG; for nonenrolled herds (controls), they refer to development over time, independent of HG. Total milk yield increased in the enrolled herds after eradication: the total milk yields in the fourth lactation were 634.2 and 873.3 kg in enrolled early and enrolled late herds, respectively, and 613.2 and 701.4 kg in the control early and control late herds, respectively. Day of peak yield differed between enrolled and control herds. The day of peak yield came on d 6 of lactation for the control early category for parities 2, 3, and 4, indicating an inability of the goats to further increase their milk yield from the initial level. For enrolled herds, on the other hand, peak yield came between d 49 and 56, indicating a gradual increase in milk yield after kidding. Our results indicate that enrollment in the HG disease eradication program improved the milk yield of dairy goats considerably, and that the multilevel cubic spline regression was a suitable model for exploring effects of disease control and eradication on milk yield.

  5. As-Built documentation of programs to implement the Robertson and Doraiswamy/Thompson models (United States)

    Valenziano, D. J. (Principal Investigator)


    The software which implements two spring wheat phenology models is described. The main program routines for the Doraiswamy/Thompson crop phenology model and the basic Robertson crop phenology model are DTMAIN and BRMAIN. These routines read meteorological data files and coefficient files, accept the planting date information and other information from the user, and initiate processing. Daily processing for the basic Robertson program consists only of calculation of the basic Robertson increment of crop development. Additional processing in the Doraiswamy/Thompson program includes the calculation of a moisture stress index and correction of the basic increment of development. Output for both consists of listings of the daily results.

  6. Fractured rock modeling in the National Waste Terminal Storage Program: a review of requirements and status

    Energy Technology Data Exchange (ETDEWEB)

    St. John, C.; Krug, A.; Key, S.; Monsees, J.


    Generalized computer codes capable of forming the basis for numerical models of fractured rock masses are being used within the NWTS program. Little additional development of these codes is considered justifiable, except in the area of representation of discrete fractures. On the other hand, model preparation requires definition of medium-specific constitutive descriptions and site characteristics and is therefore legitimately conducted by each of the media-oriented projects within the National Waste Terminal Storage program. However, it is essential that a uniform approach to the role of numerical modeling be adopted, including agreement upon the contribution of modeling to the design and licensing process and the need for, and means of, model qualification for particular purposes. This report discusses the role of numerical modeling, reviews the capabilities of several computer codes that are being used to support design or performance assessment, and proposes a framework for future numerical modeling activities within the NWTS program.

  9. Portfolio optimization by using linear programing models based on genetic algorithm (United States)

    Sukono; Hidayat, Y.; Lesmana, E.; Putra, A. S.; Napitupulu, H.; Supian, S.


    In this paper, we discussed the investment portfolio optimization using linear programming model based on genetic algorithms. It is assumed that the portfolio risk is measured by absolute standard deviation, and each investor has a risk tolerance on the investment portfolio. To complete the investment portfolio optimization problem, the issue is arranged into a linear programming model. Furthermore, determination of the optimum solution for linear programming is done by using a genetic algorithm. As a numerical illustration, we analyze some of the stocks traded on the capital market in Indonesia. Based on the analysis, it is shown that the portfolio optimization performed by genetic algorithm approach produces more optimal efficient portfolio, compared to the portfolio optimization performed by a linear programming algorithm approach. Therefore, genetic algorithms can be considered as an alternative on determining the investment portfolio optimization, particularly using linear programming models.

  17. Causal Analysis for Performance Modeling of Computer Programs

    Directory of Open Access Journals (Sweden)

    Jan Lemeire


    Full Text Available Causal modeling and the accompanying learning algorithms provide useful extensions for in-depth statistical investigation and automation of performance modeling. We enlarged the scope of existing causal structure learning algorithms by using the form-free information-theoretic concept of mutual information and by introducing the complexity criterion for selecting direct relations among equivalent relations. The underlying probability distribution of experimental data is estimated by kernel density estimation. We then reported on the benefits of a dependency analysis and the decompositional capacities of causal models. Useful qualitative models, providing insight into the role of every performance factor, were inferred from experimental data. This paper reports on the results for a LU decomposition algorithm and on the study of the parameter sensitivity of the Kakadu implementation of the JPEG-2000 standard. Next, the analysis was used to search for generic performance characteristics of the applications.

  18. NYC Epi Scholars program: promoting applied health disparities research in an urban public health department-a program model. (United States)

    Blake, Janice; Choden, Tsering; Hemans-Henry, Calaine; Koppaka, Ram; Greene, Carolyn


    Although health disparities research has already contributed to decreased mortality and morbidity in underserved communities, more work is needed. The NYC Epi Scholars program of the New York City Department of Health and Mental Hygiene (NYC DOHMH) aims to address gaps in critical public health needs and to train future public health leaders in epidemiology. The program is designed to increase racial/ethnic and socioeconomic diversity in the public health workforce, to provide fieldwork and practica opportunities, and to cultivate future leaders in epidemiology and public health. Since its inception in 2007, the NYC Epi Scholars program of the NYC DOHMH has sought talented epidemiology students interested in gaining practical experience in applied health disparities research. NYC Epi Scholars is open to graduate epidemiology students who have demonstrated achievement and leadership potential and gives them an opportunity to provide high-quality research assistance to projects that identify and address health disparities of public health significance. Many of the program's 32 alumni have made notable contributions to public health: publishing articles in peer-reviewed journals; making presentations at national and international conferences; and after graduating, pursuing careers at the DOHMH, Centers for Disease Control and Prevention, the Environmental Protection Agency, and the National Institutes of Health. Because of its noted success, the NYC Epi Scholars program may serve as a "best-practice" model for expansion in other urban health departments.

  20. Controlled Optimal Design Program for the Logit Dose Response Model

    Directory of Open Access Journals (Sweden)

    Jiaqiao Hu


    Full Text Available The assessment of dose-response is an integral component of the drug development process. Parallel dose-response studies are conducted, customarily, in preclinical and phase 1, 2 clinical trials for this purpose. Practical constraints on dose range, dose levels and dose proportions are intrinsic issues in the design of dose response studies because of drug toxicity, efficacy, FDA regulations, protocol requirements, clinical trial logistics, and marketing issues. We provide a free on-line software package called Controlled Optimal Design 2.0 for generating controlled optimal designs that can incorporate prior information and multiple objectives, and meet multiple practical constraints at the same time. Researchers can either run the web-based design program or download its stand-alone version to construct the desired multiple-objective controlled Bayesian optimal designs. Because researchers often adopt ad-hoc design schemes such as the equal allocation rules without knowing how efficient such designs would be for the design problem, the program also evaluates the efficiency of user-supplied designs.

  13. An analysis of comprehensive health promotion programs' consistency with the systems model of health. (United States)

    Meek, J


    Purpose. The purpose of this article is to report a review and analysis of the concordance between current comprehensive corporate health promotion programs as described in the published literature and the systems model of health and to explore emerging trends in the field of health promotion. Search Methods. MEDLINE, BIOSIS, and PsycINFO searches were conducted from 1985 to 1991, and the bibliographies of articles thus obtained were back searched for additional descriptions of corporate health promotion programs. Inclusive criteria included "comprehensive" corporate programs, published in peer-reviewed journals or books, and descriptions adequate enough to permit coding in the majority of analysis matrix categories. Out of 63 identified programs, 16 met the inclusion criteria; 47 were excluded. A common reason for rejection was the limitation imposed by inadequate program descriptions in the published literature. Major Findings. On average, the comprehensive corporate programs reviewed were initiated between 1984 and 1987 and set in the context of a manufacturing firm with over 10,000 employees. A minority of programs (12.5%) consistently satisfied systems model criteria. The most common category of programs were those which were inconsistent (44%), meeting some of the criteria of a systems model of health promotion, but not all. The mechanistic medical and public health models predominated strongly (63%) with the preeminent goal being individual risk factor modification. Conclusions. The limitations of the published literature do not permit strong conclusions about the number or degree to which current corporate comprehensive programs are concordant with the systems model of health. Although mechanistic models of health predominated, there is evidence that a number of comprehensive programs were inconsistent with the mechanistic model, meeting some of the criteria, but also meeting some systems model criteria. To continue the advancement of health promotion with

    Cliffe, K.A.; Morris, S.T.; Porter, J.D.


    NAMMU is a computer program for modelling groundwater flow and transport through porous media. This document provides an overview of the use of the program for geosphere modelling in performance assessment calculations and gives a detailed description of the program itself. The aim of the document is to give an indication of the grounds for having confidence in NAMMU as a performance assessment tool. In order to achieve this the following topics are discussed. The basic premises of the assessment approach and the purpose of and nature of the calculations that can be undertaken using NAMMU are outlined. The concepts of the validation of models and the considerations that can lead to increased confidence in models are described. The physical processes that can be modelled using NAMMU and the mathematical models and numerical techniques that are used to represent them are discussed in some detail. Finally, the grounds that would lead one to have confidence that NAMMU is fit for purpose are summarised

  17. Automated Generation of Formal Models from ST Control Programs for Verification Purposes

    CERN Document Server

    Fernandez Adiego, B; Tournier, J-C; Blanco Vinuela, E; Blech, J-O; Gonzalez Suarez, V


    In large industrial control systems such as the ones installed at CERN, one of the main issues is the ability to verify the correct behaviour of the Programmable Logic Controller (PLC) programs. While manual and automated testing can achieve good results, some obvious problems remain unsolved such as the difficulty to check safety or liveness properties. This paper proposes a general methodology and a tool to verify PLC programs by automatically generating formal models for different model checkers out of ST code. The proposed methodology defines an automata-based formalism used as intermediate model (IM) to transform PLC programs written in ST language into different formal models for verification purposes. A tool based on Xtext has been implemented that automatically generates models for the NuSMV and UPPAAL model checkers and the BIP framework.

    Recent results showed PPAD-completeness of the problem of computing an equilibrium for Fisher's market model under additively separable, piecewise-linear, concave utilities. We show that introducing perfect price discrimination in this model renders its equilibrium polynomial time computable. Moreover, its set of equilibria are captured by a convex program that generalizes the classical Eisenberg-Gale program, and always admits a rational solution.

  2. Microgrid Reliability Modeling and Battery Scheduling Using Stochastic Linear Programming

    Energy Technology Data Exchange (ETDEWEB)

    Cardoso, Goncalo; Stadler, Michael; Siddiqui, Afzal; Marnay, Chris; DeForest, Nicholas; Barbosa-Povoa, Ana; Ferrao, Paulo


    This paper describes the introduction of stochastic linear programming into Operations DER-CAM, a tool used to obtain optimal operating schedules for a given microgrid under local economic and environmental conditions. This application follows previous work on optimal scheduling of a lithium-iron-phosphate battery given the output uncertainty of a 1 MW molten carbonate fuel cell. Both are in the Santa Rita Jail microgrid, located in Dublin, California. This fuel cell has proven unreliable, partially justifying the consideration of storage options. Several stochastic DER-CAM runs are executed to compare different scenarios to values obtained by a deterministic approach. Results indicate that using a stochastic approach provides a conservative yet more lucrative battery schedule. Lower expected energy bills result, given fuel cell outages, in potential savings exceeding 6percent.

  3. Improving pregnancy outcome during imprisonment: a model residential care program. (United States)

    Siefert, K; Pimlott, S


    The female prison population has increased dramatically in recent years. Most women prisoners are involved with drugs, and as many as 25 percent are pregnant or have delivered within the past year. Reproductive health and drug treatment services for women in prison are inadequate, if they are available at all, and although illicit drugs are readily available in prison, drug-involved pregnant women often are incarcerated to protect fetal health. Studies of pregnancy outcome among women prisoners have demonstrated high rates of perinatal mortality and morbidity. This article examines issues related to pregnancy among women prisoners and describes an innovative residential program designed for pregnant, drug-dependent women in a state adult corrections system. Social workers can play an important role in promoting policy reform and improved services for this underserved population.

  4. Dedication Pierre Binétruy (1955 - 2017): A scientific biography

    International Nuclear Information System (INIS)


    Pierre Binétruy, born in 1955, obtained his “state doctorate” in 1980 under the direction of Mary K. Gaillard, with a thesis on “Theoretical aspects and phenomenology of gauge theories”. From 1979 to 1986, he held several positions as postdoctoral fellow at CERN and in the United States (University of California at Berkeley, University of Florida, University of Chicago). In 1986, he was recruited as a CNRS researcher at the LAPP, Annecy-le-Vieux and 4 years later as a professor at the University of Paris XI in the Laboratory of Theoretical Physics. In 2003, he was named professor at the University Paris Diderot. His main interests evolved from high-energy particle physics (notably supersymmetry) to cosmology and gravitation, and he worked in particular on the interface between the study of the primordial Universe and the theories of fundamental interactions. Recent interests included inflation models, dark energy, and the cosmic gravitational wave background. During a prolific career, he has published seminal papers that have received more than 1000 citations each. For his research he has received several awards, such as the Thibaud Prize, the Paul Langevin Award from the SFP, and was named Berkeley Miller Professor in 1999. He was arguably one of the most brilliant theorists of his time. His memory will also remain because, to paraphrase André Malraux, he combined “spirit and courage”. He knew that it is not sufficient to seek scientific truth but that one must also have the courage to organize the community for the scientific goals that this imposes and to also fight within the institutions to defend them. Our more senior colleagues will remember the extraordinary intellectual atmosphere that animated the Supersymmetry Research Group (a CNRS “groupement de recherche”), which he initiated and directed from 1997 to 2004, transforming it into an unprecedented crossroads of experimenters and theorists, of new ideas both from theory and from

Specifically, RBM is a deep learning algorithm that used in the project to increase it\\'s time performance using some efficient parallel implementation by OpenACC tool with best possible optimizations on RBM to harness the massively parallel power of NVIDIA GPUs. GPUs development in the last few years has contributed to growing the concept of deep learning. OpenACC is a directive based ap-proach for computing where directives provide compiler hints to accelerate code. The traditional Restricted Boltzmann Ma-chine is a stochastic neural network that essentially perform a binary version of factor analysis. RBM is a useful neural net-work basis for larger modern deep learning model, such as Deep Belief Network. RBM parameters are estimated using an efficient training method that called Contrastive Divergence. Parallel implementation of RBM is available using different models such as OpenMP, and CUDA. But this project has been the first attempt to apply OpenACC model on RBM.

  10. Modelling the Influence of Awareness Programs by Media on the Drinking Dynamics

    Directory of Open Access Journals (Sweden)

    Hai-Feng Huo


    Full Text Available We develop a nonlinear mathematical model with the effect of awareness programs on the binge drinking. Due to the fact that awareness programs are capable of inducing behavioral changes in nondrinkers, we introduce a separate class by avoiding contacts with the heavy drinkers. Furthermore we assume that cumulative density of awareness programs increases at a rate proportional to the number of heavy drinkers. We establish some sufficient conditions for the stability of the alcohol free and the alcohol present equilibria and give some numerical simulations to explain our main result. Our results show that awareness programs is an effective measure in reducing alcohol problems.

  11. An interdisciplinary clinical advancement program within a patient-centered care model. (United States)

    D'Avirro, J; Dotson, T; LaPierre, B; Marshall, W; Mishler, M B; Tanger, J L


    Restructuring in health care does not have to compromise the pursuit of clinical excellence and quality patient care. The clinical advancement program (CAP) at the Hospital for Special Care is a newly developed multidisciplinary reward and recognition program for clinical staff. The program is integrated into the hospital's structure of service line management and, unlike traditional advancement programs, is open to all levels of care providers: professional personnel, technical staff, and aides. This article describes the basic features of the CAP model and how its was developed by a multidisciplinary task force.

  12. Sensitivity Analysis of the Integrated Medical Model for ISS Programs (United States)

    Goodenow, D. A.; Myers, J. G.; Arellano, J.; Boley, L.; Garcia, Y.; Saile, L.; Walton, M.; Kerstman, E.; Reyes, D.; Young, M.


    Sensitivity analysis estimates the relative contribution of the uncertainty in input values to the uncertainty of model outputs. Partial Rank Correlation Coefficient (PRCC) and Standardized Rank Regression Coefficient (SRRC) are methods of conducting sensitivity analysis on nonlinear simulation models like the Integrated Medical Model (IMM). The PRCC method estimates the sensitivity using partial correlation of the ranks of the generated input values to each generated output value. The partial part is so named because adjustments are made for the linear effects of all the other input values in the calculation of correlation between a particular input and each output. In SRRC, standardized regression-based coefficients measure the sensitivity of each input, adjusted for all the other inputs, on each output. Because the relative ranking of each of the inputs and outputs is used, as opposed to the values themselves, both methods accommodate the nonlinear relationship of the underlying model. As part of the IMM v4.0 validation study, simulations are available that predict 33 person-missions on ISS and 111 person-missions on STS. These simulated data predictions feed the sensitivity analysis procedures. The inputs to the sensitivity procedures include the number occurrences of each of the one hundred IMM medical conditions generated over the simulations and the associated IMM outputs: total quality time lost (QTL), number of evacuations (EVAC), and number of loss of crew lives (LOCL). The IMM team will report the results of using PRCC and SRRC on IMM v4.0 predictions of the ISS and STS missions created as part of the external validation study. Tornado plots will assist in the visualization of the condition-related input sensitivities to each of the main outcomes. The outcomes of this sensitivity analysis will drive review focus by identifying conditions where changes in uncertainty could drive changes in overall model output uncertainty. These efforts are an integral

  13. Bourbaki's structure theory in the problem of complex systems simulation models synthesis and model-oriented programming (United States)

    Brodsky, Yu. I.


    The work is devoted to the application of Bourbaki's structure theory to substantiate the synthesis of simulation models of complex multicomponent systems, where every component may be a complex system itself. An application of the Bourbaki's structure theory offers a new approach to the design and computer implementation of simulation models of complex multicomponent systems—model synthesis and model-oriented programming. It differs from the traditional object-oriented approach. The central concept of this new approach and at the same time, the basic building block for the construction of more complex structures is the concept of models-components. A model-component endowed with a more complicated structure than, for example, the object in the object-oriented analysis. This structure provides to the model-component an independent behavior-the ability of standard responds to standard requests of its internal and external environment. At the same time, the computer implementation of model-component's behavior is invariant under the integration of models-components into complexes. This fact allows one firstly to construct fractal models of any complexity, and secondly to implement a computational process of such constructions uniformly-by a single universal program. In addition, the proposed paradigm allows one to exclude imperative programming and to generate computer code with a high degree of parallelism.

  14. A Multiobjective Programming Method for Ranking All Units Based on Compensatory DEA Model

    Directory of Open Access Journals (Sweden)

    Haifang Cheng


    Full Text Available In order to rank all decision making units (DMUs on the same basis, this paper proposes a multiobjective programming (MOP model based on a compensatory data envelopment analysis (DEA model to derive a common set of weights that can be used for the full ranking of all DMUs. We first revisit a compensatory DEA model for ranking all units, point out the existing problem for solving the model, and present an improved algorithm for which an approximate global optimal solution of the model can be obtained by solving a sequence of linear programming. Then, we applied the key idea of the compensatory DEA model to develop the MOP model in which the objectives are to simultaneously maximize all common weights under constraints that the sum of efficiency values of all DMUs is equal to unity and the sum of all common weights is also equal to unity. In order to solve the MOP model, we transform it into a single objective programming (SOP model using a fuzzy programming method and solve the SOP model using the proposed approximation algorithm. To illustrate the ranking method using the proposed method, two numerical examples are solved.

  15. A Model of Computation for Bit-Level Concurrent Computing and Programming: APEC (United States)

    Ajiro, Takashi; Tsuchida, Kensei

    A concurrent model of computation and a language based on the model for bit-level operation are useful for developing asynchronous and concurrent programs compositionally, which frequently use bit-level operations. Some examples are programs for video games, hardware emulation (including virtual machines), and signal processing. However, few models and languages are optimized and oriented to bit-level concurrent computation. We previously developed a visual programming language called A-BITS for bit-level concurrent programming. The language is based on a dataflow-like model that computes using processes that provide serial bit-level operations and FIFO buffers connected to them. It can express bit-level computation naturally and develop compositionally. We then devised a concurrent computation model called APEC (Asynchronous Program Elements Connection) for bit-level concurrent computation. This model enables precise and formal expression of the process of computation, and a notion of primitive program elements for controlling and operating can be expressed synthetically. Specifically, the model is based on a notion of uniform primitive processes, called primitives, that have three terminals and four ordered rules at most, as well as on bidirectional communication using vehicles called carriers. A new notion is that a carrier moving between two terminals can briefly express some kinds of computation such as synchronization and bidirectional communication. The model's properties make it most applicable to bit-level computation compositionally, since the uniform computation elements are enough to develop components that have practical functionality. Through future application of the model, our research may enable further research on a base model of fine-grain parallel computer architecture, since the model is suitable for expressing massive concurrency by a network of primitives.

  16. Bayesian Model Development for Analysis of Open Source Information to Support the Assessment of Nuclear Programs

    Energy Technology Data Exchange (ETDEWEB)

    Gastelum, Zoe N.; Whitney, Paul D.; White, Amanda M.


    Pacific Northwest National Laboratory has spent several years researching, developing, and validating large Bayesian network models to support integration of open source data sets for nuclear proliferation research. Our current work focuses on generating a set of interrelated models for multi-source assessment of nuclear programs, as opposed to a single comprehensive model. By using this approach, we can break down the models to cover logical sub-problems that can utilize different expertise and data sources. This approach allows researchers to utilize the models individually or in combination to detect and characterize a nuclear program and identify data gaps. The models operate at various levels of granularity, covering a combination of state-level assessments with more detailed models of site or facility characteristics. This paper will describe the current open source-driven, nuclear nonproliferation models under development, the pros and cons of the analytical approach, and areas for additional research.

  18. Compartment modelling in nuclear medicine: a new program for the determination of transfer coefficients

    International Nuclear Information System (INIS)

    Hallstadius, L.


    In many investigations concerning transport/exchange of matter in a natural system, e.g. functional studies in nuclear medicine, it is advantageous to relate experimental results to a model of the system. A new computer program is presented for the determination of linear transfer coefficients in a compartment model from experimentally observed time-compartment content curves. The program performs a least-square fit with the specified precision of the observed values as weight factors. The resulting uncertainty in the calculated transfer coefficients may also be assessed. The application of the program in nuclear medicine is demonstrated and discussed. (author)

  20. PrimeSupplier Cross-Program Impact Analysis and Supplier Stability Indicator Simulation Model (United States)

    Calluzzi, Michael


    PrimeSupplier, a supplier cross-program and element-impact simulation model, with supplier solvency indicator (SSI), has been developed so that the shuttle program can see early indicators of supplier and product line stability, while identifying the various elements and/or programs that have a particular supplier or product designed into the system. The model calculates two categories of benchmarks to determine the SSI, with one category focusing on agency programmatic data and the other focusing on a supplier's financial liquidity. PrimeSupplier was developed to help NASA smoothly transition design, manufacturing, and repair operations from the Shuttle program to the Constellation program, without disruption in the industrial supply base.

  2. A Comparison of Four Software Programs for Implementing Decision Analytic Cost-Effectiveness Models. (United States)

    Hollman, Chase; Paulden, Mike; Pechlivanoglou, Petros; McCabe, Christopher


    The volume and technical complexity of both academic and commercial research using decision analytic modelling has increased rapidly over the last two decades. The range of software programs used for their implementation has also increased, but it remains true that a small number of programs account for the vast majority of cost-effectiveness modelling work. We report a comparison of four software programs: TreeAge Pro, Microsoft Excel, R and MATLAB. Our focus is on software commonly used for building Markov models and decision trees to conduct cohort simulations, given their predominance in the published literature around cost-effectiveness modelling. Our comparison uses three qualitative criteria as proposed by Eddy et al.: "transparency and validation", "learning curve" and "capability". In addition, we introduce the quantitative criterion of processing speed. We also consider the cost of each program to academic users and commercial users. We rank the programs based on each of these criteria. We find that, whilst Microsoft Excel and TreeAge Pro are good programs for educational purposes and for producing the types of analyses typically required by health technology assessment agencies, the efficiency and transparency advantages of programming languages such as MATLAB and R become increasingly valuable when more complex analyses are required.

  3. Curriculum inventory: Modeling, sharing and comparing medical education programs. (United States)

    Ellaway, Rachel H; Albright, Susan; Smothers, Valerie; Cameron, Terri; Willett, Timothy


    Abstract descriptions of how curricula are structured and run. The American National Standards Institute (ANSI) MedBiquitous Curriculum Inventory Standard provides a technical syntax through which a wide range of different curricula can be expressed and subsequently compared and analyzed. This standard has the potential to shift curriculum mapping and reporting from a somewhat disjointed and institution-specific undertaking to something that is shared among multiple medical schools and across whole medical education systems. Given the current explosion of different models of curricula (time-free, competency-based, socially accountable, distributed, accelerated, etc.), the ability to consider this diversity using a common model has particular value in medical education management and scholarship. This article describes the development and structure of the Curriculum Inventory Standard as a way of standardizing the modeling of different curricula for audit, evaluation and research purposes. It also considers the strengths and limitations of the current standard and the implications for a medical education world in which this level of commonality, precision, and accountability for curricular practice is the norm rather than the exception.

  4. Prenatal centrifugation: A model for fetal programming of adult weight? (United States)

    Baer, Lisa A.; Rushing, Linda; Wade, Charles E.; Ronca, April E.


    'Fetal programming' is a newly emerging field that is revealing astounding insights into the prenatal origins of adult disease, including metabolic, endocrine, and cardiovascular pathophysiology. In the present study, we tested the hypothesis that rat pups conceived, gestated and born at 2-g have significantly reduced birth weights and increased adult body weights as compared to 1-g controls. Offspring were produced by mating young adult male and female rats that were adapted to 2-g centrifugation. Female rats underwent conception, pregnancy and birth at 2-g. Newborn pups in the 2-g condition were removed from the centrifuge and fostered to non-manipulated, newly parturient dams maintained at 1-g. Comparisons were made with 1-g stationary controls, also cross- fostered at birth. As compared to 1-g controls, birth weights of pups gestated and born at 2-g were significantly reduced. Pup body weights were significantly reduced until Postnatal day (P)12. Beginning on P63, body weights of 2-g-gestated offspring exceeded those of 1-g controls by 7-10%. Thus, prenatal rearing at 2-g restricts neonatal growth and increases adult body weight. Collectively, these data support the hypothesis that 2-g centrifugation alters the intrauterine milieu, thereby inducing persistent changes in adult phenotype.

  5. Modeling hospital infrastructure by optimizing quality, accessibility and efficiency via a mixed integer programming model. (United States)

    Ikkersheim, David; Tanke, Marit; van Schooten, Gwendy; de Bresser, Niels; Fleuren, Hein


    The majority of curative health care is organized in hospitals. As in most other countries, the current 94 hospital locations in the Netherlands offer almost all treatments, ranging from rather basic to very complex care. Recent studies show that concentration of care can lead to substantial quality improvements for complex conditions and that dispersion of care for chronic conditions may increase quality of care. In previous studies on allocation of hospital infrastructure, the allocation is usually only based on accessibility and/or efficiency of hospital care. In this paper, we explore the possibilities to include a quality function in the objective function, to give global directions to how the 'optimal' hospital infrastructure would be in the Dutch context. To create optimal societal value we have used a mathematical mixed integer programming (MIP) model that balances quality, efficiency and accessibility of care for 30 ICD-9 diagnosis groups. Typical aspects that are taken into account are the volume-outcome relationship, the maximum accepted travel times for diagnosis groups that may need emergency treatment and the minimum use of facilities. The optimal number of hospital locations per diagnosis group varies from 12-14 locations for diagnosis groups which have a strong volume-outcome relationship, such as neoplasms, to 150 locations for chronic diagnosis groups such as diabetes and chronic obstructive pulmonary disease (COPD). In conclusion, our study shows a new approach for allocating hospital infrastructure over a country or certain region that includes quality of care in relation to volume per provider that can be used in various countries or regions. In addition, our model shows that within the Dutch context chronic care may be too concentrated and complex and/or acute care may be too dispersed. Our approach can relatively easily be adopted towards other countries or regions and is very suitable to perform a 'what-if' analysis.

  7. [Opportunities of team psychotherapy in hospice-palliative care. Results of a model program]. (United States)

    Kegye, Adrienne; Pádi, Eva


    Hospice care has been developing for 20 years. In the framework of the high standard palliative treatment hospice care involves symptom control as well as the psychosocial support of patients and their relatives. Developed as a model, the aims of the psychoeducational and supporting program were to reduce the psychological symptoms, form the active coping mechanisms, reduce feeling of isolation and help the communication of the patients treated in the Oncological Rehabilitation and Hospice Department of the Vaszary Kolos Hospital in Esztergom, Hungary. The program consisted of the following elements: analiticly orientated team psychoterapy, creative occupation, physiotherapy, dietetics guidance and oncological consulting. During the model supporting program the authors observed significant changes in both the patients and staff members which had a positive impact on the department's operation and the atmosphere, too. The model program showed that in team work can give beneficial and cost-efficient psychosocial support to patients using the carers' energy in the most effective way.

  8. Culturally relevant model program to prevent and reduce agricultural injuries. (United States)

    Helitzer, D L; Hathorn, G; Benally, J; Ortega, C


    Limited research has explored pesticide injury prevention among American Indian farmers. In a five-year agricultural intervention, a university-community partnership, including the University of New Mexico School of Medicine, New Mexico State University, Shiprock Area Cooperative Extension Service, and Navajo Nation communities, used a culturally relevant model to introduce and maintain safe use of integrated pest management techniques. We applied the Diffusion of Innovations theory and community-based approaches to tailor health promotion strategies for our intervention. In a longitudinal study with repeated measures, we trained six "model farmers" to be crop management experts in pesticide safety, application, and control. Subsequently, these model farmers worked with 120 farm families randomized into two groups: intervention (Group 1) and delayed intervention (Group 2). Measurements included a walk-through analysis, test of knowledge and attitudes, and yield analysis. Both groups demonstrated improvements in pesticide storage behaviors after training. Test scores regarding safety practices improved significantly: from 57.3 to 72.4 for Group 1 and from 52.6 to 76.3 for Group 2. Group 1 maintained their knowledge and safety practices after the intervention. Attitudes about pesticides and communication of viewpoints changed across the study years. With pesticides and fertilizer, the number of corn ears increased by 56.3% and yield (kg m(-2)) of alfalfa increased by 41.2%. The study combined traditional farming practices with culturally relevant approaches and behavior change theory to affect knowledge, safety practices, attitudes, communication channels, and crop yield. Storage behaviors, use of pesticides and safety and application equipment, and safety practice knowledge changed significantly, as did attitudes about social networking, social support, and the compatibility and relative advantage of pesticides for farms.

  10. Translation techniques for distributed-shared memory programming models

    Energy Technology Data Exchange (ETDEWEB)

    Fuller, Douglas James [Iowa State Univ., Ames, IA (United States)


    The high performance computing community has experienced an explosive improvement in distributed-shared memory hardware. Driven by increasing real-world problem complexity, this explosion has ushered in vast numbers of new systems. Each new system presents new challenges to programmers and application developers. Part of the challenge is adapting to new architectures with new performance characteristics. Different vendors release systems with widely varying architectures that perform differently in different situations. Furthermore, since vendors need only provide a single performance number (total MFLOPS, typically for a single benchmark), they only have strong incentive initially to optimize the API of their choice. Consequently, only a fraction of the available APIs are well optimized on most systems. This causes issues porting and writing maintainable software, let alone issues for programmers burdened with mastering each new API as it is released. Also, programmers wishing to use a certain machine must choose their API based on the underlying hardware instead of the application. This thesis argues that a flexible, extensible translator for distributed-shared memory APIs can help address some of these issues. For example, a translator might take as input code in one API and output an equivalent program in another. Such a translator could provide instant porting for applications to new systems that do not support the application's library or language natively. While open-source APIs are abundant, they do not perform optimally everywhere. A translator would also allow performance testing using a single base code translated to a number of different APIs. Most significantly, this type of translator frees programmers to select the most appropriate API for a given application based on the application (and developer) itself instead of the underlying hardware.

  11. Evidence, models, conservation programs and limits to management (United States)

    Nichols, J.D.


    Walsh et al. (2012) emphasized the importance of obtaining evidence to assess the effects of management actions on state variables relevant to objectives of conservation programs. They focused on malleefowl Leipoa ocellata, ground-dwelling Australian megapodes listed as vulnerable. They noted that although fox Vulpes vulpes baiting is the main management action used in malleefowl conservation throughout southern Australia, evidence of the effectiveness of this action is limited and currently debated. Walsh et al. (2012) then used data from 64 sites monitored for malleefowl and foxes over 23 years to assess key functional relationships relevant to fox control as a conservation action for malleefowl. In one set of analyses, Walsh et al. (2012) focused on two relationships: fox baiting investment versus fox presence, and fox presence versus malleefowl population size and rate of population change. Results led to the counterintuitive conclusion that increases in investments in fox control produced slight decreases in malleefowl population size and growth. In a second set of analyses, Walsh et al. (2012) directly assessed the relationship between investment in fox baiting and malleefowl population size and rate of population change. This set of analyses showed no significant relationship between investment in fox population control and malleefowl population growth. Both sets of analyses benefited from the incorporation of key environmental covariates hypothesized to influence these management relationships. Walsh et al. (2012) concluded that "in most situations, malleefowl conservation did not effectively benefit from fox baiting at current levels of investment." In this commentary, I discuss the work of Walsh et al. (2012) using the conceptual framework of structured decision making (SDM). In doing so, I accept their analytic results and associated conclusions as accurate and discuss basic ideas about evidence, conservation and limits to management.

    Kurylo, M. J.; DeCola, P. L.; Kaye, J. A.


    Under the mandate contained in the FY 1976 NASA Authorization Act, the National Aeronautics and Space Administration (NASA) has developed and is implementing a comprehensive program of research, technology development, and monitoring of the Earth's upper atmosphere, with emphasis on the upper troposphere and stratosphere. This program aims at expanding our chemical and physical understanding to permit both the quantitative analysis of current perturbations as well as the assessment of possible future changes in this important region of our environment. It is carried out jointly by the Upper Atmosphere Research Program (UARP) and the Atmospheric Chemistry Modeling and Analysis Program (ACMAP), both managed within the Research Division in the Office of Earth Science at NASA. Significant contributions to this effort have also been provided by the Atmospheric Effects of Aviation Project (AEAP) of NASA's Office of Aero-Space Technology. The long-term objectives of the present program are to perform research to: understand the physics, chemistry, and transport processes of the upper troposphere and the stratosphere and their control on the distribution of atmospheric chemical species such as ozone; assess possible perturbations to the composition of the atmosphere caused by human activities and natural phenomena (with a specific emphasis on trace gas geographical distributions, sources, and sinks and the role of trace gases in defining the chemical composition of the upper atmosphere); understand the processes affecting the distributions of radiatively active species in the atmosphere, and the importance of chemical-radiative-dynamical feedbacks on the meteorology and climatology of the stratosphere and troposphere; and understand ozone production, loss, and recovery in an atmosphere with increasing abundances of greenhouse gases. The current report is composed of two parts. Part 1 summarizes the objectives, status, and accomplishments of the research tasks supported

  13. An Analysis of OpenACC Programming Model: Image Processing Algorithms as a Case Study

    Directory of Open Access Journals (Sweden)

    M. J. Mišić


    Full Text Available Graphics processing units and similar accelerators have been intensively used in general purpose computations for several years. In the last decade, GPU architecture and organization changed dramatically to support an ever-increasing demand for computing power. Along with changes in hardware, novel programming models have been proposed, such as NVIDIA’s Compute Unified Device Architecture (CUDA and Open Computing Language (OpenCL by Khronos group. Although numerous commercial and scientific applications have been developed using these two models, they still impose a significant challenge for less experienced users. There are users from various scientific and engineering communities who would like to speed up their applications without the need to deeply understand a low-level programming model and underlying hardware. In 2011, OpenACC programming model was launched. Much like OpenMP for multicore processors, OpenACC is a high-level, directive-based programming model for manycore processors like GPUs. This paper presents an analysis of OpenACC programming model and its applicability in typical domains like image processing. Three, simple image processing algorithms have been implemented for execution on the GPU with OpenACC. The results were compared with their sequential counterparts, and results are briefly discussed.

  16. A multi-objective programming model for assessment the GHG emissions in MSW management

    International Nuclear Information System (INIS)

    Mavrotas, George; Skoulaxinou, Sotiria; Gakis, Nikos; Katsouros, Vassilis; Georgopoulou, Elena


    Highlights: • The multi-objective multi-period optimization model. • The solution approach for the generation of the Pareto front with mathematical programming. • The very detailed description of the model (decision variables, parameters, equations). • The use of IPCC 2006 guidelines for landfill emissions (first order decay model) in the mathematical programming formulation. - Abstract: In this study a multi-objective mathematical programming model is developed for taking into account GHG emissions for Municipal Solid Waste (MSW) management. Mathematical programming models are often used for structure, design and operational optimization of various systems (energy, supply chain, processes, etc.). The last twenty years they are used all the more often in Municipal Solid Waste (MSW) management in order to provide optimal solutions with the cost objective being the usual driver of the optimization. In our work we consider the GHG emissions as an additional criterion, aiming at a multi-objective approach. The Pareto front (Cost vs. GHG emissions) of the system is generated using an appropriate multi-objective method. This information is essential to the decision maker because he can explore the trade-offs in the Pareto curve and select his most preferred among the Pareto optimal solutions. In the present work a detailed multi-objective, multi-period mathematical programming model is developed in order to describe the waste management problem. Apart from the bi-objective approach, the major innovations of the model are (1) the detailed modeling considering 34 materials and 42 technologies, (2) the detailed calculation of the energy content of the various streams based on the detailed material balances, and (3) the incorporation of the IPCC guidelines for the CH 4 generated in the landfills (first order decay model). The equations of the model are described in full detail. Finally, the whole approach is illustrated with a case study referring to the application

  7. A new neural network model for solving random interval linear programming problems. (United States)

    Arjmandzadeh, Ziba; Safi, Mohammadreza; Nazemi, Alireza


    This paper presents a neural network model for solving random interval linear programming problems. The original problem involving random interval variable coefficients is first transformed into an equivalent convex second order cone programming problem. A neural network model is then constructed for solving the obtained convex second order cone problem. Employing Lyapunov function approach, it is also shown that the proposed neural network model is stable in the sense of Lyapunov and it is globally convergent to an exact satisfactory solution of the original problem. Several illustrative examples are solved in support of this technique. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. Possibility/Necessity-Based Probabilistic Expectation Models for Linear Programming Problems with Discrete Fuzzy Random Variables

    Directory of Open Access Journals (Sweden)

    Hideki Katagiri


    Full Text Available This paper considers linear programming problems (LPPs where the objective functions involve discrete fuzzy random variables (fuzzy set-valued discrete random variables. New decision making models, which are useful in fuzzy stochastic environments, are proposed based on both possibility theory and probability theory. In multi-objective cases, Pareto optimal solutions of the proposed models are newly defined. Computational algorithms for obtaining the Pareto optimal solutions of the proposed models are provided. It is shown that problems involving discrete fuzzy random variables can be transformed into deterministic nonlinear mathematical programming problems which can be solved through a conventional mathematical programming solver under practically reasonable assumptions. A numerical example of agriculture production problems is given to demonstrate the applicability of the proposed models to real-world problems in fuzzy stochastic environments.

    This paper describes an innovative evaluation model applied to TRANSPETRO's 'Marine Terminals Standardization Program' based on updating approaches of programs evaluation and organizational learning. Since the program was launched in 2004, the need for having an evaluation model able to evaluate its implementation progress, to measure the degree of standards compliance and its potential economic, social and environmental impacts has become evident. Within a vision of safe and environmentally responsible operations of marine terminals, this evaluation model was jointly designed by TRANSPETRO and PUC-Rio to promote continuous improvement and learning in operational practices and in the standardization process itself. TRANSPETRO believes that standardization supports its services and management innovation capability by creating objective and internationally recognized parameters, targets and metrology for its business activities. The conceptual model and application guidelines for this important tool are presented in this paper, as well as the next steps towards its implementation. (author)

  10. Model-based schedulability analysis of safety critical hard real-time Java programs

    DEFF Research Database (Denmark)

    Bøgholm, Thomas; Kragh-Hansen, Henrik; Olsen, Petur


    In this paper, we present a novel approach to schedulability analysis of Safety Critical Hard Real-Time Java programs. The approach is based on a translation of programs, written in the Safety Critical Java profile introduced in [21] for the Java Optimized Processor [18], to timed automata models...... verifiable by the Uppaal model checker [23]. Schedulability analysis is reduced to a simple reachability question, checking for deadlock freedom. Model-based schedulability analysis has been developed by Amnell et al. [2], but has so far only been applied to high level specifications, not actual...... implementations in a programming language. Experiments show that model-based schedulability analysis can result in a more accurate analysis than possible with traditional approaches, thus systems deemed non-schedulable by traditional approaches may in fact be schedulable, as detected by our analysis. Our approach...

  11. Support Method of Model Description Error Detection on a Programming Environment for Multi Agent Simulation (United States)

    Itakura, Kota; Hatakeyama, Go; Akiyoshi, Masanori; Komoda, Norihisa

    Recently, there are various proposals on tool for multi-agent simulation. However, in such simulation tools, analysts who do not have programming skill spend a lot of time to develop programs because notation of simulation models is not defined sufficiently and programming language is varied on tools. To solve this problem, a programming environment that defines the notation of simulation model has poposed. In this environment, analysts can design simulation with a graph representation and get the program code without writing programs. However, it is difficult to find errors that cause unintended behavior in simulation. Therefore, we propose a support method as a model debugger which helps users to find errors. The debugger generates candidates of errors, using a user's report of unintended behavior based on “typical report patterns”. Candidates of errors are extracted from “tree structure of error-inducing factors” that consists of source patterns of errors. In this paper, we executed experiments that compare time needed for examinees to find errors. Experimental results show the time to find errors by utilizing our model debugger is shortened.

  14. Sustainable Cost Models for mHealth at Scale: Modeling Program Data from m4RH Tanzania. (United States)

    Mangone, Emily R; Agarwal, Smisha; L'Engle, Kelly; Lasway, Christine; Zan, Trinity; van Beijma, Hajo; Orkis, Jennifer; Karam, Robert


    There is increasing evidence that mobile phone health interventions ("mHealth") can improve health behaviors and outcomes and are critically important in low-resource, low-access settings. However, the majority of mHealth programs in developing countries fail to reach scale. One reason may be the challenge of developing financially sustainable programs. The goal of this paper is to explore strategies for mHealth program sustainability and develop cost-recovery models for program implementers using 2014 operational program data from Mobile for Reproductive Health (m4RH), a national text-message (SMS) based health communication service in Tanzania. We delineated 2014 m4RH program costs and considered three strategies for cost-recovery for the m4RH program: user pay-for-service, SMS cost reduction, and strategic partnerships. These inputs were used to develop four different cost-recovery scenarios. The four scenarios leveraged strategic partnerships to reduce per-SMS program costs and create per-SMS program revenue and varied the structure for user financial contribution. Finally, we conducted break-even and uncertainty analyses to evaluate the costs and revenues of these models at the 2014 user volume (125,320) and at any possible break-even volume. In three of four scenarios, costs exceeded revenue by $94,596, $34,443, and $84,571 at the 2014 user volume. However, these costs represented large reductions (54%, 83%, and 58%, respectively) from the 2014 program cost of $203,475. Scenario four, in which the lowest per-SMS rate ($0.01 per SMS) was negotiated and users paid for all m4RH SMS sent or received, achieved a $5,660 profit at the 2014 user volume. A Monte Carlo uncertainty analysis demonstrated that break-even points were driven by user volume rather than variations in program costs. These results reveal that breaking even was only probable when all SMS costs were transferred to users and the lowest per-SMS cost was negotiated with telecom partners. While this

  16. Treatment effects model for assessing disease management: measuring outcomes and strengthening program management. (United States)

    Wendel, Jeanne; Dumitras, Diana


    This paper describes an analytical methodology for obtaining statistically unbiased outcomes estimates for programs in which participation decisions may be correlated with variables that impact outcomes. This methodology is particularly useful for intraorganizational program evaluations conducted for business purposes. In this situation, data is likely to be available for a population of managed care members who are eligible to participate in a disease management (DM) program, with some electing to participate while others eschew the opportunity. The most pragmatic analytical strategy for in-house evaluation of such programs is likely to be the pre-intervention/post-intervention design in which the control group consists of people who were invited to participate in the DM program, but declined the invitation. Regression estimates of program impacts may be statistically biased if factors that impact participation decisions are correlated with outcomes measures. This paper describes an econometric procedure, the Treatment Effects model, developed to produce statistically unbiased estimates of program impacts in this type of situation. Two equations are estimated to (a) estimate the impacts of patient characteristics on decisions to participate in the program, and then (b) use this information to produce a statistically unbiased estimate of the impact of program participation on outcomes. This methodology is well-established in economics and econometrics, but has not been widely applied in the DM outcomes measurement literature; hence, this paper focuses on one illustrative application.

  17. Biography of Aureal T. Cross: World class coal geologist, palynologist, paleobotanist and educator

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, Tom L. [Department of Plant Biology, School of Integrative Biology, University of Illinois, Urbana, IL 61801 (United States)


    An Ohioan by birth, June 4, 1916, in Findlay, Hancock County, Aureal T. Cross grew up an Iowan on a dairy farm near Waterloo at Castle Hill. He was the second of five children of Congregational Minister Raymond W. and Mrs. Myra Jane Coon Cross. Aureal's grade school education was mostly in a one-room school at Castle Hill, then to East Waterloo, junior high and high school, where music was as important as farm work before and after classes. On a history and music scholarship at Coe College in Cedar Rapids, Aureal was drawn to L. R. Wilson's physical geology course and the summer reconnaissance trips. Graduating from Coe College in 1939 with an honors thesis on pollen analysis, Aureal completed his Masters in 1941 and a PhD thesis in 1943 at the University of Cincinnati with J. H. Hoskins on Pennsylvanian age plants from coal-balls. During 1942-1946 he taught premedical U.S. Navy students at the University of Notre Dame with a 1943-1944 leave as a National Research Council Fellow. Aureal and Christina Aleen Teyssier met during 1943 in Pittsburgh and married in 1945. Aureal replaced K. E. Caster, his paleontology mentor, for three and one half years (1946-1949) in the Geology Department at Cincinnati, and did field mapping for the Ohio Geological Survey during the summers. Cross established (1949-1957) productive graduate training and research programs in the West Virginia University Geology Department and the West Virginia Geologic and Economic Survey where he had dual appointments. His move (1957-1961) to Exploration Geology, at Amoco's Pan American Petroleum Corporation Research Center in Tulsa, Oklahoma, permitted him to develop and supervise a major palynological research group. The return to academia (1961) at Michigan State University in East Lansing resulted in one of the most comprehensive graduate training programs in paleobotany, palynology, biostratigraphy and paleoecology in North America. Although Aureal Cross officially retired in 1986

  18. HPC parallel programming model for gyrokinetic MHD simulation

    Naitou, Hiroshi; Yamada, Yusuke; Tokuda, Shinji; Ishii, Yasutomo; Yagi, Masatoshi


    The 3-dimensional gyrokinetic PIC (particle-in-cell) code for MHD simulation, Gpic-MHD, was installed on SR16000 (“Plasma Simulator”), which is a scalar cluster system consisting of 8,192 logical cores. The Gpic-MHD code advances particle and field quantities in time. In order to distribute calculations over large number of logical cores, the total simulation domain in cylindrical geometry was broken up into N DD-r × N DD-z (number of radial decomposition times number of axial decomposition) small domains including approximately the same number of particles. The axial direction was uniformly decomposed, while the radial direction was non-uniformly decomposed. N RP replicas (copies) of each decomposed domain were used (“particle decomposition”). The hybrid parallelization model of multi-threads and multi-processes was employed: threads were parallelized by the auto-parallelization and N DD-r × N DD-z × N RP processes were parallelized by MPI (message-passing interface). The parallelization performance of Gpic-MHD was investigated for the medium size system of N r × N θ × N z = 1025 × 128 × 128 mesh with 4.196 or 8.192 billion particles. The highest speed for the fixed number of logical cores was obtained for two threads, the maximum number of N DD-z , and optimum combination of N DD-r and N RP . The observed optimum speeds demonstrated good scaling up to 8,192 logical cores. (author)

  19. Educational Program Evaluation Model, From the Perspective of the New Theories

    Directory of Open Access Journals (Sweden)

    Soleiman Ahmady


    Full Text Available Introduction: This study is focused on common theories that influenced the history of program evaluation and introduce the educational program evaluation proposal format based on the updated theory. Methods: Literature searches were carried out in March-December 2010 with a combination of key words, MeSH terms and other free text terms as suitable for the purpose. A comprehensive search strategy was developed to search Medline by the PubMed interface, ERIC (Education Resources Information Center and the main journal of medical education regarding current evaluation models and theories. We included all study designs in our study. We found 810 articles related to our topic, and finally 63 with the full text article included. We compared documents and used expert consensus for selection the best model. Results: We found that the complexity theory using logic model suggests compatible evaluation proposal formats, especially with new medical education programs. Common components of a logic model are: situation, inputs, outputs, and outcomes that our proposal format is based on. Its contents are: title page, cover letter, situation and background, introduction and rationale, project description, evaluation design, evaluation methodology, reporting, program evaluation management, timeline, evaluation budget based on the best evidences, and supporting documents. Conclusion: We found that the logic model is used for evaluation program planning in many places, but more research is needed to see if it is suitable for our context.

  20. Implementing three evidence-based program models: early lessons from the Teen Pregnancy Prevention Replication Study. (United States)

    Kelsey, Meredith; Layzer, Jean


    This article describes some of the early implementation challenges faced by nine grantees participating in the Teen Pregnancy Prevention Replication Study and their response to them. The article draws on information collected as part of a comprehensive implementation study. Sources include site and program documents; program officer reports; notes from site investigation, selection and negotiation; ongoing communications with grantees as part of putting the study into place; and semi-structured interviews with program staff. The issues faced by grantees in implementing evidence-based programs designed to prevent teen pregnancy varied by program model. Grantees implementing a classroom-based curriculum faced challenges in delivering the curriculum within the constraints of school schedules and calendars (program length and size of class). Grantees implementing a culturally tailored curriculum faced a series of challenges, including implementing the intervention as part of the regular school curriculum in schools with diverse populations; low attendance when delivered as an after-school program; and resistance on the part of schools to specific curriculum content. The third set of grantees, implementing a program in clinics, faced challenges in identifying and recruiting young women into the program and in retaining young women once they were in the program. The experiences of these grantees reflect some of the complexities that should be carefully considered when choosing to replicate evidence-based programs. The Teen Pregnancy Prevention replication study will provide important context for assessing the effectiveness of some of the more widely replicated evidence-based programs.
