Red Mandela: Contests of auto-biography and Auto/biography in South Africa

Directory of Open Access Journals (Sweden)

Ciraj Rassool

Full Text Available This article examines the case of the red Mercedes-Benz built in 1990 by workers at the Mercedes-Benz plant in East London and presented to Nelson Mandela as a gift shortly after his release from prison. During the 1990s a biographic order marked by a discourse of heroic leaders was growing in South Africa, where biographic narration and self-narration played a noticeable and, at times, substantial part in political transformation and reconstruction. Nelson Mandela's 'long walk to freedom' became the key trope for South Africa's history, narrated as the triumph of reconciliation. The presentation of the car to Nelson Mandela in 1990 occurred at a time of transition in the life of his auto/biography, from the biography of desire for the absent revolutionary leader to the biography of a statesman and president. This partly explains the ambiguous, double-edged history of the gift, as a labour of love on the part of NUMSA workers and as donation by Mercedes-Benz South Africa (the corporate version of these events emphasised the 'friendship' that was 'sparked' between Nelson Mandela and Mercedes-Benz South Africa. Inspired by the East London autoworkers' commitment to produce the car for Mandela, as well as by the resilience some of them showed during their nine-week strike and sleep-in in the plant soon afterwards, Simon Gush's installation Red has intervened in how those events should be remembered. By choosing to exhibit the disassembled body panels of a replica car alongside reconstructed displays of sleep-in strike beds made of scaffolding, foam, upholstery and car headrests, with imagined uniforms of striking workers, Gush has chosen to appropriate the history of the events of 1990 from the celebratory frames of the Mandela biographic order. The installation turns into an inquiry into the labour process and the events of the strike that was critical of the reconciliatory and celebratory understanding of the gift as a product of a partnership

Whey protein stories - An experiment in writing a multidisciplinary biography.

2016-12-01

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.

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

Science.gov (United States)

Moxham, Noah

2016-03-01

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.

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

2017-01-01

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.

Sylvia Plath and the Dangers of Biography

Directory of Open Access Journals (Sweden)

Selma Asotić

2015-09-01

Full Text Available 2013 marked the 50th anniversary of the death of Sylvia Plath and was commemorated by a flurry of new publications on the life and work of the late poet. The renewed interest in Sylvia Plath also revitalized the decades-old debate on the interdependence of her poems and her biography. This paper investigates and problematizes the way in which poetry in general and the work of Sylvia Plath in particular are read and interpreted. It tries to shed some light on the “biographical fallacy” which has for so long plagued critical approaches to her work and shows ways in which S. Plath’s own poetic method differs from the method of confessional writers such as Robert Lowell, in the hope of revealing why S. Plath’s work cannot and should not be approached through the prism of her biography.

The lived experience of volunteering in a palliative care biography service.

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

2015-10-01

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.

[History of thought tendencies in biography - a cultural historical synopsis].

Science.gov (United States)

Dieckhöfer, K

1980-01-01

Biography, presumably, the oldest form of historiography, is rudimentally already found in the Attic comedy. Reference is made to Xenophon and his representation of leading personalities and predominance problems as well as to Aristotle through whose school the empiric exploration of the individual personality in philosophy was firmly established. To Theophrast's pictures of human weakness are added new psychological aspects under Aristoxenos. In the biographical work of Nepos the picture of the habits of famous men was shown on a subhistorical level. While Plutarch's character descriptions are fully rationalistic there can be no doubt that a moral value judgement is passed. The Concepts "experience" and "inner development" were therefore unknown in the antique biography. Herder, as the onset of the writing of scientific biographies, is considered the promotor of an objectivating biographical and autobiographical method. Reference is made to Dilthey's theory of knowledge and his theory of cognition, particularly to his cultural-historical approach, whereby a close relationship to Gruhle ("understanding psychology"), Jaspers ("The art of sympathising understanding") as well as Birnbaum ("pathographic methodology") becomes evident.

The many lives of Charles Darwin: early biographies and the definitive evolutionist.

Science.gov (United States)

Lightman, Bernard

2010-12-20

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.

Non-authorized biographies and the ilegitimacy of fiction

Directory of Open Access Journals (Sweden)

Melina Girardi Fachin

2016-08-01

Full Text Available This article aims at reflecting about non-authorized biographies. The choice of exploring the topic not only through law but in a dialog with literature opens up new theoretical horizons. The limits of the social subject as well as the limits of the fictional character in a narrative are not always clear in order to define the borders between intimacy and public life. As for Law, a recent trial by the Brazilian Supreme Court, the Direct Action of Unconstitutionality (Ação Direta de Inconstitucionalidade – ADI 4815, shed more light on the subject, which, nonetheless, is still unconcluded, considering how generic the guarantees of freedom of expression and intimacy defense are in the Brazilian constitutional order. Keeping all that in mind and considering that previous authorization for the publication of biographies is a form of censorship, our intention is to debate the topic considering the density and the new ideas that literature can offer.

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.

KARL JASPERS’ INTELLECTUAL BIOGRAPHY OR EXPERIENCE OF HISTORICAL RESEARCH OF PHILISOPHER’S LIFE AND WORK

Султана Гильмидиновна Кцоева

Full Text Available The article is devoted to a such genre of historical research as intellectual biography. 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.

Telling different stories, making new realities: The ontological politics of 'addiction' biographies.

Science.gov (United States)

Pienaar, Kiran; Dilkes-Frayne, Ella

2017-06-01

Personal narratives of alcohol and other drug addiction circulate widely in popular culture and they also have currency in professional therapeutic settings. Despite this, relatively little research has explored the conventions operating in these narratives and how they shape people's experiences and identities. While research in this area often proceeds on the premise that addiction biographies are straightforwardly 'true' accounts, in this paper we draw on the insights of critical alcohol and other drug scholarship, and the concept of 'ontological politics' to argue that biographies produce normative ideas about addiction and those said to be experiencing it. Our analysis compares traditional addiction narratives with the biographies we reconstructed from qualitative interviews with 60 people in Australia who describe themselves as having an 'addiction', 'dependence' or drug 'habit'. We track how addiction is variously enacted in these accounts and comment on the effects of particular enactments. By attending to the ways in which people cope, even thrive, with the kind of consumption that would attract a diagnosis of addiction or dependence, the biographies we produced disrupt the classic narrative of increasing drug use, decline and eventual collapse. Doing so allows for consideration of the benefits of consumption, as well as the ways that people carefully regulate it to minimise harms. It also constitutes individuals as active in managing consumption-an important move that challenges dominant understandings of addiction as a disorder of compulsivity. We conclude by considering the implications of our attempt to provide an alternative range of narratives, which resonate with people's diverse experiences. Crown Copyright © 2017.

Albert Einstein a biography

CERN Document Server

Fölsing, Albrecht

1997-01-01

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.

AHP 40: Review: The Social Life of Tibetan Biography

Full Text Available The book under review is a part of Lexington Books' series "Studies in Modern Tibetan Culture." The author, Amy Holmes-Tagchungdarpa, has a background in Religious Studies and researched the interrelationships between textual biography and social community networks of the Tibetan Buddhist lineage holder and Mahāmudrā and Dzogchen master, Tokden Shakya Shri (1853–1919 from Latokh, which at the time was a kingdom and one of five polities in Kham, Eastern Tibet, and today is in Chamdo County in the Tibet Autonomous Region. She interviewed contemporary students and family of Shakya Shri as well as translated excerpts from the master's biography, the Garland of Flowers. The Tibetan text is not appended, but interested readers can refer to the complete translation of the Garland of Flowers by Elio Guarisco (2009. An old black and white photo of the master, as well as photos of his community in Nepal and the stupas his followers helped to renovate, are included in the book. A map showing the regions of Shakya Shri's residences and spiritual influence would have been useful. ...

THE BIOGRAPHIES OF ROMAN EMPERORS BY KOŽIČIĆ. FAITHFULNESS TO THE SOURCE AND ORIGINALITY IN TRANSLATING

Directory of Open Access Journals (Sweden)

Tomislav Mrkonjić

2012-01-01

Full Text Available The question relating to the dependence on the source, namely, the matter concerning the originality of the translation of Kožičić’s Biographies (Knjižice od žitija rimskih arhijerejov i cesarov, Rijeka, 1531 was resolved only partially by Günther Tutschke for the reason that he didn’t know the source of the Biographies of the Roman emperors. Since the author of this article has ascertained that the biographical source on the emperors was the work of Giovanni Battista Cipelli (Egnatius, De Caesaribus libri tres, in this article he wishes to present the context in which the translations were produced, compare the structure of the source with the translation, juxtapose the texts known as “Excursus” (De Parthorum et Persarum imperio, Romae captivitas, Maomethis ortus, De origine Turcarum as well as compare individual biographies. The conclusion is that Kožičić demonstrated a certain level of originality in his translations regarding the structure, the selection and elaboration of the “Excursus”, and in converting particular terminology. In many instances he integrated the biographies with the information regarding the local history, especially concerning Croats and southern Slavs.

Athletes confessions: the sports biography as an interaction ritual.

Science.gov (United States)

Thing, L F; Ronglan, L T

2015-04-01

Commercialization of emotions is not a new phenomenon but in Denmark there is a new general trend to tell and sell personal stories in the media. Personal deprivation and crises are also major topics in sports media. This paper focuses on sports biographies as a book genre that is reviving in popularity. The paper approaches the topic through the biographies of one Danish athlete: the former professional cyclist, Jesper Skibby, who writes about his doping disclosure and shares his personal dilemmas as a former elite sportsman. The thematic text analysis orientates around social interactions, emotions, and personality constructions. Inspired by microsociology with a Durkheimian flavor of Goffman and Hochschild, themes including "face work," "interaction rituals," and "emotions management" are discussed. The analysis claims that sharing personal information in the media is not only a means of confession and reclaiming status but is also business and management - on an intimate level. Telling the story of the corrosion of a sporting character has become a hot issue, an entertainment, and not least a commercial commitment. © 2014 John Wiley & Sons A/S.

An experimental ‘Life’ for an experimental life : Richard Waller's biography of Robert Hooke (1705)

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...

Re-working biographies: Women's narratives of pregnancy whilst living with epilepsy.

Science.gov (United States)

Weckesser, Annalise; Denny, Elaine

2017-07-01

This paper explores the multiple ways experiences of pregnancy and early motherhood come to 'rework' the biographies of women living with epilepsy. Pregnancy is explored as a temporarily concurrent status alongside the long-term condition of epilepsy. Narrative interviews were conducted with 32 women from across the UK. Analysis of these narratives suggests that biographical disruption and continuity are both useful in the conceptualisation of women's diverse experiences of pregnancy and epilepsy. Such findings challenge the notion that the presence of a condition over a long period of time leads to the normalisation of illness. Participants' narratives demonstrate that, for some, pregnancy and early motherhood may be disruptive and can raise concerns regarding an ever present condition that may previously have been taken for granted. Findings also indicate the need for a greater consideration of gender and care responsibilities, as well explorations of concomitant conditions, in the theorising of biographies and chronic illness.

American Prometheus. The Triumph and Tragedy of J. Robert Oppenheimer. Biography; J. Robert Oppenheimer. Die Biographie

Energy Technology Data Exchange (ETDEWEB)

Bird, Kai; Sherwin, Martin J.

2009-07-01

A definitive portrait of legendary scientist J. Robert Oppenheimer, the ''father'' of the atomic bomb, discusses his seminal role in the twentieth-century scientific world, as well as his lesser-known roles as family man, supposed communist, and head of Princeton's Institute for Advanced Studies. ''American Prometheus'' is a rich evocation of America in mid-century and a compelling portrait of scientist J. Robert Oppenheimer, a man shaped by its major events--the Depression, World War II, and the Cold War. (orig.) [German] J. Robert Oppenheimer (1904-1967), der ''Vater der Atombombe'', zaehlt zu den schillerndsten Figuren der juengeren Zeitgeschichte. Fuer ihre glaenzende Biographie des ''amerikanischen Prometheus'' erhielten der Journalist Kai Bird und der Historiker Martin J. Sherwin den Pulitzer-Preis. Exemplarisch lassen sie das Drama eines Forschers lebendig werden, der sich zwischen Erkenntnisdrang und ethischer Verantwortung entscheiden muss. Oppenheimer leitete das streng geheime Manhattan-Projekt in der Wueste von New Mexico, wo am 16. Juli 1945 die erste Atombombe gezuendet wurde. Kurz darauf starben in Hiroshima und Nagasaki mehr als 200 000 Menschen durch die neue ''Wunderwaffe'' - die Menschheit war ins Atomzeitalter eingetreten. Erschuettert von der Zerstoerungskraft seiner Schoepfung, engagierte sich Oppenheimer fortan gegen den Einsatz nuklearer Waffen. Das machte ihn im Amerika der McCarthy-Aera verdaechtig. Er geriet ins Visier des FBI, wurde als Spion der Sowjetunion verleumdet und musste den Staatsdienst quittieren. Sein Privatleben wurde an die Oeffentlichkeit gezerrt, seine Wohnung verwanzt, sein Telefon abgehoert. Erst 1963 rehabilitierte ihn Praesident Kennedy. Ueber dreissig Jahre hinweg haben die Autoren Interviews mit Oppenheimers Angehoerigen, Freunden und Kollegen gefuehrt, FBI-Akten gesichtet, Tonbaender von Reden und Verhoeren

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.

TRACES OF MEMORY. PRELIMINARY REMARKS ON IDENTITY AND BIOGRAPHY OF CRIMEAN TATARS

Directory of Open Access Journals (Sweden)

Irena Borowik

2011-01-01

Full Text Available The article is devoted to the preliminary analysis of biographical interviews, taken with representatives of Crimean Tatars returning to Crimean Peninsula and settling in the places that they or their ancestors used to live before deportation. The research was conducted in summer of 2008 and 2009, 20 interviews were taken with consideration of age, sex, place of living and level of education. Traces of memory are understood in this article as repeatable elements of biographical narratives. By this virtue those repeated elements refer not only to individual identity but they also build collective identity, more precisely national in this case. The key element of the article is the third part of it where relations between memory and identity are explored in collected biographies. As it appeared in all life-stories deportation from Crimea and return after years are crucial elements of construction of biographies and in all cases it has a form of trajectories. The general conclusion is that memory of these painful events and celebration of it is functional for building the strong collective identity which is based on traditional values, religious and political integration of national minority.

With his discovery that measuring values of complementary fundamental quantities in the microscopic world cannot by arbitrarily precisely determined cutted Werner Heisenberg the Gordian knot for the finishing of quantum theory developed by Planck, Einstein, and others and opened by this a new ''golden era'' in the physics of the 20th century. On the base of the documents from his life and work, i. e. deeds, letters and reports of contemporaries, as well as the published and unpublished essays, books, and articles of Heisenberg - also the later on found, publications or manuscripts mainly coming from the inheritance - resulted this systematic biography of Heisenberg. The author, the last doctoral candidate of Heisenberg relied furthermore on factual and personal knowledges, mainly own remembrances on his doctoral father and his teachers, colleagues, and students. Because of the interest of an authentical biography of the theoretical physicist Heisenberg the presentation of the mathematical approaches and the corresponding derivations could not completely be abandoned. This biography appeals by this both to a scientifically cultivated as a wider in science interested audience and covers the first phase of Heisenberg's life until his Nobel price 1933. [German] Mit seiner Entdeckung, dass sich Messwerte komplementaerer Groessen in der mikroskopischen Welt nicht beliebig genau bestimmen lassen, durchschnitt Werner Heisenberg den Gordischen Knoten zur Vollendung der von Planck, Einstein und anderen entwickelten Quantentheorie und eroeffnete damit ein neues ''goldenes Zeitalter'' in der Physik des 20.

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

Directory of Open Access Journals (Sweden)

Thomas Hinton

2017-05-01

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.

A life of Erwin Schroedinger; Erwin Schroedinger. Eine Biographie

Energy Technology Data Exchange (ETDEWEB)

Moore, Walter J.

2012-07-01

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

Posthumous Testimony for Dr. Leo Gross and his Family / Restoration of the 'Lost' Biography of a Physician Victim of the Holocaust

Science.gov (United States)

Hildebrandt, Sabine; Von Villiez, Anna; Seidelman, William E

At a time when the last direct witnesses of the Holocaust are passing, new approaches to the restoration of 'lost' biographies of victims need to be considered. This investigation describes the potential of an international collaboration including surviving family members. Archival documents discovered in Jerusalem in 1983 concerned a discussion on the cancellation of a medical licence for a German Jewish physician, Dr. Leo Gross of Kolberg, who had been disenfranchised from medical practice under Nazi law. After applying for a medical licence during a 1935 visit to Palestine, Gross remigrated to Germany, where he was imprisoned in a concentration camp. No further information was found until 2014, when a group of scholars linked a variety of archival and internet-accessible sources and located a nephew of Gross. The nephew's testimony, cross-referenced against data from other sources, enabled the reconstruction of the 'lost' biography of his uncle and family, in fact a posthumous testimony. The resulting narrative places Dr. Leo Gross within his professional and social network, and serves his commemoration within this context of family and community. The restored biography of Dr. Leo Gross presents an exemplary case study for the future of Holocaust testimony.

Selective neurophysiologic responses to music in instrumentalists with different listening biographies.

Science.gov (United States)

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

2009-01-01

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.

The personal is professional: Connecting white urban middle school science teachers' biographies to their teaching of all students

Science.gov (United States)

Oey, Esther Ruth

The purpose of this study was to examine if and in what ways white, urban middle school science teachers use experiences of being marginalized or feeling different to connect to students coming from backgrounds unlike their own---especially students who are racially, culturally, linguistically and otherwise different from them, the school culture and the dominant society. Personal biography was used to frame this study. Data consisted of structured and semi-structured interviews and classroom observations of one female and two male science teachers gathered over one academic year. Results indicated that experiences with difference may be used to inform teachers' practices, but personal biography alone was insufficient to enable the teachers to reflect on their experiences with race, class, gender, and difference. Also, attending to emotions appeared to be an important factor in helping students develop cognitive skills in science classrooms.

The Physicist and Astronomer Christoper Scheiner - Biography Letters, Works

Science.gov (United States)

Daxecker, Franz

The Jesuit priest Christopher Scheiner was one of the most influential astronomers of the first half of the 17th century. He was a creative and down-to-earth natural scientist who worked in the fields of astronomy, physics, optics and ophthalmology, while following his vocations as university lecturer, church builder and pastor. In scientific matters he was Galilei's opponent. Their dispute centred on the priority of discovery in regard to the sunspots. Scheiner was not the first to discover the sunspots, but he gave the most detailed account thereofin his main work "Rosa Ursina sive Sol". He was, however, ceaseless in his defense of the geocentric system. In 1891, Anton v.Braunmühl published a biography of Father Scheiner. Ever since then, new documents have come to light, justifying the publication of a new biography. Among the documents now available is Scheiner's hitherto unknown dissertation. Notes taken during his lectures in Ingolstadt provide valuable information on astronomy using the telescope, an invention of his lifetime. His exchange of letters with personalities like Archduke Leopold V of Austria-Tyrol, with scientists like Magini, Galilei, Gassendi, Kepler and confriars Rader, Guldin, Alber, Minutuli, Cysat und Kircher is a source of precious insights. Letters to Scheiner from the Father Generals of his order display evidence of his superiors' zero tolerance for the helincentric system. They also disclose Scheiner's wish to become a missionary in China, the financial difficulties he faced while trying to find a publisher for his "Rosa Ursina sive Sol" and his personal shortcomings. A Scheiner obituary from 1650 was found in Cracow in 2001. It contains information on the troublesome last years of his life and has finally allowed us to determine the year of his birth. Scheiner's personality has been praised as well as criticized by many authors - sometimes depending on their ideological backgrounds. This holds true especially regarding the argument

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.

Full Text Available I. Kotlyarevsky is an outstanding personality in the history of Ukrainian literature, whose name has become for many people a symbol of Ukraine, a symbol of spiritual unity around national values. It is not a surprise that the figure of the writer became not only the object of numerous scientific works, but also a source of inspiration for masters of artistic word. B. Levin іn his time made artistic exploration of the phenomenon of I. Kotlyarevsky. B. Levin’s interest of I. Kotlyarevsky emerged during large-scale preparation of Ukrainian community to celebrate the 200 anniversary of the birth of the writer. In 1969 B. Levin wrote the story “Evenings of Academic republic” by order of the memorial museum. It was included in the collection “Wreath to I. Kotlyarevsky”. This work engendered writer’s plan to elaborate biography of famous poltavets more detail. For almost twenty years (1972–1990 on the basis of collected and processed factual material B. Levin wrote a novel, in which seven- stories reflected the most important periods of Kotlyarevsky’s life. Kotlyarevsky’s biography in B. Levin's novel „Funny sage” is analyzed in the article; focused on the character of interactions of known biographical facts about the writer, supported by documentary material, from the author’s fiction. By artistic interpretation of writer’s life way B. Levin showed again a great importance of I. Kotlyarevsky in historical and cultural life of Ukraine.

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

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

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.

Full Text Available Recently the investigation of linguistic biographies has become popular among linguists for several reasons. Instead of studying formally-oriented, traditional approaches to second language acquisition and language learning, such research focuses on an individual’s conceptualisation of languages, language acquisition and living with and among multiple languages. Linguistic biographies can be either oral or written narratives, elicited by a researcher or produced by individuals. This includes language-learning memoirs as well. As some studies have demonstrated, a closer look at a linguistic history of a particular individual helps to discover new aspects that generally remain unnoticed in formally-oriented studies, such as the speaker’s personal attitudes, emotions attached to his/ her languages, self-expression in different languages, and instances of multilingual speech (for example, cross-linguistic influence, code-switching, etc.. However, a multilingual person’s narratives, either in written or oral form, should be treated with caution. It has been demonstrated in recent studies that grounded theory approach (i.e., coding and establishing emergent categories and content analysis alone cannot present a full picture of a linguistic biography. As Pavlenko (2007 argues, at least three kinds of reality should be considered: subject reality (how the narrator sees his/her life with multiple languages, text reality (that is, how the text of narration is structured, in what order events are presented and life reality (biographical facts. As in fieldwork in general, a researcher should be prepared to face discrepancies between the picture presented by the informant and other types of reality. From a methodological point of view, an informant should be interviewed several times in his/her different languages or, at the very least; a researcher should be familiar with the languages. In this sense, the European tradition of linguistic biographies

A life of Erwin Schroedinger. 2. ed.; Erwin Schroedinger. Eine Biographie

Moore, Walter J.

2015-07-01

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.

Ibn Isḥāq’s biography of Muḥammad and its epitome by Ibn Hishām were products of their time. A case of self-censorship applied by one of Ibn Isḥāq’s informants and two cases of censorship applied by Ibn Hishām, who omitted many of his predecessor’s materials, contribute to a better understanding of the social and political context of the biography.El estudio de la producción literaria medieval sobre la vida de Muḥammad debe ir de la mano del estudio de su historia, empresa para la que disponemos de rica información en una variedad de fuentes.

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

Directory of Open Access Journals (Sweden)

Jeannine Hayat

2007-01-01

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.

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

2007-10-01

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.

A Biography Between Spaces: M.N. Roy, from Indian nationalism to Mexican communism

Directory of Open Access Journals (Sweden)

Michael Goebel

2013-04-01

Full Text Available This paper traces the global travels of Indian revolutionary Manabendra Nath Roy (1884-1954, with special attention to the tension between nationalism and communism in his transnational political writings and networks. In particular, the article examines Roy's sojourn in revolutionary Mexico between 1917 and 1920, time during which he approached Marxism and signed as one of the founders of the Mexican Communist Party. The paper is therefore based on Roy's own writings, as well as on German and British diplomatic documents. The example of Roy's trajectory is used here to advance a number of more general arguments of theoretical nature regarding the advantages and problems of a transnational  historiography and its relation to biography as a historiographical genre.

The value of human life in contemporary society. The global biography project.

Science.gov (United States)

Nary, G

1997-12-01

The closing address at the 1997 First International Conference on Healthcare Resource Allocation for HIV/AIDS and Other Life-Threatening Illnesses is presented. The address discusses the extrinsic value of life and the three forms of material value: spiritual, economic, and political, placed on life by an outside source. It is argued that if spiritual currency, rather than economic or political currency, drove public policy there would be greater progress in reducing the global rate of HIV and more options for care. Further, lack of identity of those afflicted with HIV reduces them to mere statistics, thus decreasing their economic and political clout. Giving identities to people who are sick not only increases empathy but also increases their survivability. The establishment of the Global Biography Project seeks to reestablish spiritual currency as the international currency that underlies every nation's healthcare policies.

Directory of Open Access Journals (Sweden)

Susanne Bressan

2012-07-01

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.

Adolescent Agentic Orientations: Contemporaneous Family Influence, Parental Biography and Intergenerational Development.

Science.gov (United States)

Johnson, Monica Kirkpatrick; Hitlin, Steven

2017-10-01

Agentic orientations developed in adolescence have been linked to better health, well-being, and achievements in the years following. This study examines longitudinal parental influences on the development of adolescent children's agentic orientations, captured by the core constructs of mastery beliefs and generalized life expectations. Drawing on multigenerational panel data from the United States (1991-2011), the study examines contemporaneous family factors, but also how parental biographies (their own transition to adulthood) and parents' own adolescent agentic orientations influence their adolescent children. Study adolescents were 46% male, 52% white, and 15.6 years old on average. The findings indicate that parents' early orientations and experiences in the transition to adulthood have little effect on their children's mastery beliefs, but that parents' generalized life expectations (in adolescence) and having married before having the child were associated with their children's more optimistic life expectations. Contemporaneous family income and optimistic expectations among parents-as-adolescents were somewhat substitutable as positive influences on adolescents' optimistic life expectations. The findings contribute to our understanding of intergenerational and over-time influences on these key adolescent orientations.

HIV-positive men who have sex with men: biography, diversity in lifestyles, common experience of living with HIV. ANRS-EN12 VESPA Study, 2003.

2010-01-01

The conceptualisation of male who have sex with male (MSM) to account for male homosexual behaviour has been developed to facilitate the endorsement of prevention message since the advent of HIV infection. Population studies performed to understand and monitor sexual and preventive behaviour usually recruit respondents through gay-friendly channels such as media, sexual venues or festivals, leading to recruitment bias. Few studies question possible differences according to varying sexual biography and current behaviour within the MSM population. The random sample of HIV+ individuals treated in specialised outpatient clinics (ANRS-EN12-VESPA study, 2003) provides the opportunity to question the MSM conceptualisation regarding sexual biography, social characteristics, current sexual behaviour, use of condom, living with HIV (quality of life, discrimination and participation in NGOs). Among the 2932 respondents, 1309 men reported a lifetime male sexual partner. Information regarding sexual biography (lifetime and current numbers of male and female sexual partners, lifetime number of male and female stable couples) was computed using cluster analysis and identified five profiles: exclusive gay (53.7%), gay with some bisexuality (21.8%), gay with mixed sexual history (8.1%), bisexual (7.8%) and heterosexual with male-to-male sex (8.6%). The profiles matched self-identification better among the most exclusive homosexuals than among men with current bisexuality. These five subgroups differed regarding demographic and social characteristics (except migration status), their period of diagnosis, age and CD4 count at diagnosis. Sexual activity, steady partnership, number of male and female partners, use of sexual venues and illegal substance use were different across subgroups. Reversely, these groups are homogenous regarding experience of discrimination and involvement in People living with HIV/AIDS (PLWHA) activities. These findings among men living with HIV support the MSM

Full Text Available Many programming models for massively parallel machines exist, and each has its advantages and disadvantages. In this article we present a programming model that combines features from other programming models that (1 can be efficiently implemented on present and future Cray Research massively parallel processor (MPP systems and (2 are useful in constructing highly parallel programs. The model supports several styles of programming: message-passing, data parallel, global address (shared data, and work-sharing. These styles may be combined within the same program. The model includes features that allow a user to define a program in terms of the behavior of the system as a whole, where the behavior of individual tasks is implicit from this systemic definition. (In general, features marked as shared are designed to support this perspective. It also supports an opposite perspective, where a program may be defined in terms of the behaviors of individual tasks, and a program is implicitly the sum of the behaviors of all tasks. (Features marked as private are designed to support this perspective. Users can exploit any combination of either set of features without ambiguity and thus are free to define a program from whatever perspective is most appropriate to the problem at hand.

An Account of ... William Cullen: John Thomson and the Making of a Medical Biography.

Science.gov (United States)

Shuttleton, David E

2014-01-01

John Thomson's An Account of the Life, Lectures and Writings of William Cullen (1832; 1859) remains a primary source for the career of the most influential academic physician in eighteenth-century Scotland and is also a significant work of medical history. But this multi-authored text, begun around 1810 by the academic surgeon, John Thomson, but only completed in 1859 by Dr David Craigie, has its own complex history. This chapter addresses what this history can reveal about the development of medical biography as a literary genre. It argues that the Account is a hybrid work shaped by a complex array of practical, domestic, intellectual, and professional pressures, as Thomson, in seeking to bolster his own career, was caught between the demands of Cullen's children for a traditional "Life" and his own more theoretical and socio-cultural interests.

Boudenot, J.C. [Thales, 91 - Palaiseau (France)

2009-01-15

This article presents a short biography of Pauli in which we find the most important facts of his scientific career and some stunning sides of his personality. Pauli was born in 1900 in Vienna in an intellectual family. He was very soon interested in physics. At the age of 21 he published a relevant article on relativity, and the same year he presented a doctorate thesis on the quantum description of the H{sub 2}{sup +} molecular ion. As soon as 1925, Pauli discovered the exclusion principle (for which he will receive the Nobel prize in 1945), and was the first to calculate the energy levels of the hydrogen atom by using the Heisenberg formalism. In 1930, he suggested the existence of an unknown particle (the neutrino) to explain the continuous spectrum of the beta decay. In 1934, he found a link between the spin and the quantum statistics that is now called the spin-statistic theorem. Pauli died in december 1958 from a pancreas tumor. (A.C.)

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.

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

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.

Full Text Available Programs and project evaluation models can be extremely useful in project planning and management. The aim is to set the right questions as soon as possible in order to see in time and deal with the unwanted program effects, as well as to encourage the positive elements of the project impact. In short, different evaluation models are used in order to minimize losses and maximize the benefits of the interventions upon small or large social groups. This article introduces some of the most recently used evaluation models.

Bookshelf. John Adams biography

International Nuclear Information System (INIS)

Billinge, Roy

1993-01-01

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

Natalia Astrachan

2014-11-01

Full Text Available Biography of Socrates is regarded as a kind of artistic text, deliberately turned philosopher to all citizens of the Athenian Polis, built in ethical and aesthetic coordinates that are relevant in the development plan of the ancient drama, its two leading genres of tragedy and Comedy. The fate of Socrates interpreted as requiring reflection in the plane of intersection of the tragic and the comic, the interrelated experiences of tragic and comic catharsis. Fear and compassion of catharsis tragic, laughter and pleasure of catharsis comedy cover the fullness of the emotional spectrum, characterizing the relationship between the individual and the human community in their movement from the past through present to future. Comic unity of people takes place in space history, the background of the established, time-tested values. Tragic overcoming fragmentation one and many – to-background values are desirable or antivalues unwanted catastrophic future, the road to which pave risky individualistic actions of the tragic hero, artistically meaningful in the tragedy, under control of the human community. The discrepancy between the tragic fate of Socrates and his image in the Comedy of Aristophanes “Clouds” shows the essence of the relationship of individual and shares in the process of artistic creation and reception. Socratic dialogue, as well as ancient tragedy and Comedy are characterized from the point of view of their role in the formation of individual literary and artistic creativity. Ahead of the author of the literary works of his contemporaries associated with the process of artistic creativity, facing in the future. This is ahead of the curve generates the contradiction between the past and the future in the space of literary works, which may be resolved by the reception and interpretation.

Model Checker for Java Programs

Visser, Willem

2007-01-01

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.

A holographic model of reminiscence in the poetry of Czesław Miłosz

Directory of Open Access Journals (Sweden)

Agnieszka Rydz

2011-01-01

Full Text Available For a model of nostalgic memory in the poetry of Czesław Miłosz, based on the psychological phenomenon of reminiscence, an allegoric counterpart can be identified in the hologram metaphor (Douwe Draaisma. The question: “Who am I” – reappears in Miłosz’s late lyrical poetry when he ponders over both his biography and the biographies of others. The response is provided, for instance, in the concept of human dialectic biography (of subject and object, formulated by Paul Ricoeur in his philosophical analyses. Human memory remains equally dialectic, placed in the antinomy between memory and oblivion. Still, retrieving a detail which has been remembered evokes all experience along with its rich context. That is the holographic effect, described in literature as the “ghost image”. Also in poetry, the effacing of memory trace does not make a barrier for the restitution of recollection. “The Sun of Memory” beams through the lyric of the author of the collection of poems “This”.

Chim, Justine M Y

2014-01-01

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.

Interactive differential equations modeling program

International Nuclear Information System (INIS)

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

1976-01-01

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

The need for improving the representation of cloud processes in climate models has been one of the most important limitations of the reliability of climate-change simulations. Now in its third year, the National Science Foundation-funded Center for Multi-scale Modeling of Atmospheric Processes (CMMAP) at Colorado State University is addressing this problem through a revolutionary new approach to representing cloud processes on their native scales, including the cloud-scale interaction processes that are active in cloud systems. CMMAP has set ambitious education and human-resource goals to share basic information about the atmosphere, clouds, weather, climate, and modeling with diverse K-12 and public audiences through its affiliation with the Windows to the Universe (W2U) program at University Corporation for Atmospheric Research (UCAR). W2U web pages are written at three levels in English and Spanish. This information targets learners at all levels, educators, and families who seek to understand and share resources and information about the nature of weather and the climate system, and career role models from related research fields. This resource can also be helpful to educators who are building bridges in the classroom between the sciences, the arts, and literacy. Visitors to the W2U's CMMAP web portal can access a beautiful new clouds image gallery; information about each cloud type and the atmospheric processes that produce them; a Clouds in Art interactive; collections of weather-themed poetry, art, and myths; links to games and puzzles for children; and extensive classroom- ready resources and activities for K-12 teachers. Biographies of CMMAP scientists and graduate students are featured. Basic science concepts important to understanding the atmosphere, such as condensation, atmosphere pressure, lapse rate, and more have been developed, as well as 'microworlds' that enable students to interact with experimental tools while building fundamental knowledge

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

Directory of Open Access Journals (Sweden)

Nancy Cushing

2009-11-01

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.

Havelund, Klaus; Pressburger, Thomas

2000-01-01

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.

Cultural and Corporate Belonging in the Course of Transnational Biographies: A Case Study of a Sierra Leonean Immigrant in Germany

Directory of Open Access Journals (Sweden)

Jan Küver

2009-09-01

Full Text Available How does cultural and corporate affiliation emerge in transnational biographies? How does it develop under the influence of global and national power structures? These questions are addressed in this study that combines epistemological approaches dealing with the interplay of social and individual factors in identity formation with a structural analysis of historical power relations in form of racism and colonialism. Empirically this paper identifies how immigrants deal with challenges of integration into the host society and incorporate these experiences into their biographical self-construction. It concentrates on African and particularly Sierra Leonean immigrants in Germany. The findings are generated from a reconstructive analysis of selected biographical narrations which were scrutinized from different perspectives. URN: urn:nbn:de:0114-fqs0903234

The Buddhist Tzu Chi Silent Mentor Program promotes the donation of one's body to science as a selfless act by appealing to the Buddhist ethics of compassion and self-sacrifice. Together, faculty, families, and donors help medical students to learn the technical, spiritual, emotional, and psychological aspects of medicine. Students assigned to each "Silent Mentor" visit the family to learn about the donor's life. They see photos and hear family members' stories. Afterwards, students write a brief biography of the donor which is posted on the program website, in the medical school, and on the dissection table. In this paper, we: (1) summarize the Silent Mentor Program; (2) describe findings from an assessment of medical students who recently completed a new version of the program in Malaysia; and (3) explore how healthcare settings could benefit from this innovative program.

Unifying Model-Based and Reactive Programming within a Model-Based Executive

Science.gov (United States)

Williams, Brian C.; Gupta, Vineet; Norvig, Peter (Technical Monitor)

1999-01-01

Real-time, model-based, deduction has recently emerged as a vital component in AI's tool box for developing highly autonomous reactive systems. Yet one of the current hurdles towards developing model-based reactive systems is the number of methods simultaneously employed, and their corresponding melange of programming and modeling languages. This paper offers an important step towards unification. We introduce RMPL, a rich modeling language that combines probabilistic, constraint-based modeling with reactive programming constructs, while offering a simple semantics in terms of hidden state Markov processes. We introduce probabilistic, hierarchical constraint automata (PHCA), which allow Markov processes to be expressed in a compact representation that preserves the modularity of RMPL programs. Finally, a model-based executive, called Reactive Burton is described that exploits this compact encoding to perform efficIent simulation, belief state update and control sequence generation.

Scientists as role models in space science outreach

Science.gov (United States)

Alexander, D.

The direct participation of scientists significantly enhances the impact of any E/PO effort. This is particularly true when the scientists come from minority or traditionally under-represented groups and, consequently, become role models for a large number of students while presenting positive counter-examples to the usual stereotypes. In this paper I will discuss the impact of scientists as role models through the successful implementation of a set of space physics games and activities, called Solar Week. Targetted at middle-school girls, the key feature of Solar Week is the "Ask a Scientist" section enabling direct interaction between participating students and volunteer scientists. All of the contributing scientists are women, serving as experts in their field and providing role models to whom the students can relate. Solar Week has completed four sessions with a total of some 140 edcuators and 12,000+ students in over 28 states and 9 countries. A major success of the Solar Week program has been the ability of the students to learn more about the scientists as people, through online biographies, and to discuss a variety of topics ranging from science, to careers and common hobbies.

Lu, D R; Mao, F

1993-05-01

A computer program, PharmK, was developed for pharmacokinetic modeling of experimental data. The program was written in C computer language based on the high-level user-interface Macintosh operating system. The intention was to provide a user-friendly tool for users of Macintosh computers. An interactive algorithm based on the exponential stripping method is used for the initial parameter estimation. Nonlinear pharmacokinetic model fitting is based on the maximum likelihood estimation method and is performed by the Levenberg-Marquardt method based on chi 2 criterion. Several methods are available to aid the evaluation of the fitting results. Pharmacokinetic data sets have been examined with the PharmK program, and the results are comparable with those obtained with other programs that are currently available for IBM PC-compatible and other types of computers.

Academic program models for undergraduate biomedical engineering.

Krishnan, Shankar M

2014-01-01

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

RFQ modeling computer program

International Nuclear Information System (INIS)

Potter, J.M.

1985-01-01

The mathematical background for a multiport-network-solving program is described. A method for accurately numerically modeling an arbitrary, continuous, multiport transmission line is discussed. A modification to the transmission-line equations to accommodate multiple rf drives is presented. An improved model for the radio-frequency quadrupole (RFQ) accelerator that corrects previous errors is given. This model permits treating the RFQ as a true eight-port network for simplicity in interpreting the field distribution and ensures that all modes propagate at the same velocity in the high-frequency limit. The flexibility of the multiport model is illustrated by simple modifications to otherwise two-dimensional systems that permit modeling them as linear chains of multiport networks

Developing robotic behavior using a genetic programming model

Pryor, R.J.

1998-01-01

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

Testing the Structure of Hydrological Models using Genetic Programming

Science.gov (United States)

Selle, B.; Muttil, N.

2009-04-01

Genetic Programming is able to systematically explore many alternative model structures of different complexity from available input and response data. We hypothesised that genetic programming can be used to test the structure hydrological models and to identify dominant processes in hydrological systems. To test this, genetic programming was used to analyse a data set from a lysimeter experiment in southeastern Australia. The lysimeter experiment was conducted to quantify the deep percolation response under surface irrigated pasture to different soil types, water table depths and water ponding times during surface irrigation. Using genetic programming, a simple model of deep percolation was consistently evolved in multiple model runs. This simple and interpretable model confirmed the dominant process contributing to deep percolation represented in a conceptual model that was published earlier. Thus, this study shows that genetic programming can be used to evaluate the structure of hydrological models and to gain insight about the dominant processes in hydrological systems.

Database structure for plasma modeling programs

International Nuclear Information System (INIS)

Dufresne, M.; Silvester, P.P.

1993-01-01

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

Evolution of a minimal parallel programming model

International Nuclear Information System (INIS)

Lusk, Ewing; Butler, Ralph; Pieper, Steven C.

2017-01-01

Here, we take a historical approach to our presentation of self-scheduled task parallelism, a programming model with its origins in early irregular and nondeterministic computations encountered in automated theorem proving and logic programming. We show how an extremely simple task model has evolved into a system, asynchronous dynamic load balancing (ADLB), and a scalable implementation capable of supporting sophisticated applications on today’s (and tomorrow’s) largest supercomputers; and we illustrate the use of ADLB with a Green’s function Monte Carlo application, a modern, mature nuclear physics code in production use. Our lesson is that by surrendering a certain amount of generality and thus applicability, a minimal programming model (in terms of its basic concepts and the size of its application programmer interface) can achieve extreme scalability without introducing complexity.

This paper proposes a model-based training program for the skills necessary to operate advance avionics systems that incorporate advanced autopilots and fight management systems. The training model is based on a formalism, the operational procedure model, that represents the mission model, the rules, and the functions of a modem avionics system. This formalism has been defined such that it can be understood and shared by pilots, the avionics software, and design engineers. Each element of the software is defined in terms of its intent (What?), the rationale (Why?), and the resulting behavior (How?). The Advanced Computer Tutoring project at Carnegie Mellon University has developed a type of model-based, computer aided instructional technology called cognitive tutors. They summarize numerous studies showing that training times to a specified level of competence can be achieved in one third the time of conventional class room instruction. We are developing a similar model-based training program for the skills necessary to operation the avionics. The model underlying the instructional program and that simulates the effects of pilots entries and the behavior of the avionics is based on the operational procedure model. Pilots are given a series of vertical flightpath management problems. Entries that result in violations, such as failure to make a crossing restriction or violating the speed limits, result in error messages with instruction. At any time, the flightcrew can request suggestions on the appropriate set of actions. A similar and successful training program for basic skills for the FMS on the Boeing 737-300 was developed and evaluated. The results strongly support the claim that the training methodology can be adapted to the cockpit.

Testing the structure of a hydrological model using Genetic Programming

Selle, Benny; Muttil, Nitin

2011-01-01

SummaryGenetic Programming is able to systematically explore many alternative model structures of different complexity from available input and response data. We hypothesised that Genetic Programming can be used to test the structure of hydrological models and to identify dominant processes in hydrological systems. To test this, Genetic Programming was used to analyse a data set from a lysimeter experiment in southeastern Australia. The lysimeter experiment was conducted to quantify the deep percolation response under surface irrigated pasture to different soil types, watertable depths and water ponding times during surface irrigation. Using Genetic Programming, a simple model of deep percolation was recurrently evolved in multiple Genetic Programming runs. This simple and interpretable model supported the dominant process contributing to deep percolation represented in a conceptual model that was published earlier. Thus, this study shows that Genetic Programming can be used to evaluate the structure of hydrological models and to gain insight about the dominant processes in hydrological systems.

Programming for the Public Good: Ensuring Public Value Through the Cooperative Extension Program Development Model

Directory of Open Access Journals (Sweden)

Nancy Franz

2015-06-01

Full Text Available Effective Cooperative Extension programs produce important private and public value for individuals, families, businesses, and communities. However, the public value of Extension programming often goes unmeasured and unarticulated. Extension needs to reclaim its role as a key provider of public value for Land-Grant Universities through strong educational programs driven by infusing public value into all elements of the Extension Program Development Model. This article describes Extension’s public value movement including organizational, professional, program, and scholarship development efforts to enhance public good effectiveness articulation. Lessons learned, implications, and next steps for Extension’s public value success through a strong program development model are also shared.

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

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

ModelArchiver—A program for facilitating the creation of groundwater model archives

Science.gov (United States)

Winston, Richard B.

2018-03-01

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, https://water.usgs.gov/admin/memo/GW/gw2016.02.pdf, https://water.usgs.gov/ogw/policy/gw-model/). 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.

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...

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.

Hawkins, Stephanie R; Clinton-Sherrod, A Monique; Irvin, Neil; Hart, Laurie; Russell, Sarah Jane

2009-01-01

Sexual violence is a growing public health problem, and there is an urgent need to develop sexual violence prevention programs. Logic models have emerged as a vital tool in program development. The Centers for Disease Control and Prevention funded an empowerment evaluation designed to work with programs focused on the prevention of first-time male perpetration of sexual violence, and it included as one of its goals, the development of program logic models. Two case studies are presented that describe how significant positive changes can be made to programs as a result of their developing logic models that accurately describe desired outcomes. The first case study describes how the logic model development process made an organization aware of the importance of a program's environmental context for program success; the second case study demonstrates how developing a program logic model can elucidate gaps in organizational programming and suggest ways to close those gaps.

Programming biological models in Python using PySB.

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

2013-01-01

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.

2016-05-01

Full Text Available This article proposes and tests a set of performance indicators for the assessment of Bachelor and Master studies, from two perspectives: the study programs and the disciplines. The academic performance at the level of a study program shall be calculated based on success and efficiency rates, and at discipline level, on the basis of rates of efficiency, success and absenteeism. This research proposes a model of classification of the study programs within a Bachelor and Master cycle based on the education performance and efficiency. What recommends this model as a best practice model in academic management is the possibility of grouping a study program or a discipline in a particular category of efficiency

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

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.

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

1978-04-01

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.

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.

Logic integer programming models for signaling networks.

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

2009-05-01

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.

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

A CONCEPTUAL MODEL OF THE LIFE CYCLE OF THE PROGRAM

Марія Костянтинівна СУХОНОС

2016-02-01

Full Text Available A conceptual model of the life cycle of the program is proposed. This model is based on the value approach. As a resulting index, it uses a category of complex structural value. This model renders the process of the life cycle of the program in the context of time/result. It assumes the presence of four basic phases of the life cycle, namely, initiation, planning, executing and closing. Also, this model formalizes interconnection of management processes of integration of program and management of its community and subprocesses. Selection of a value approach for the forming of a resulting index of a program determines by a variety of results of the program. This is a result of its variety and complexity in the process of finding a criterion for evaluation. Worked out a mechanism for assessing the value of the program. It consists of four steps and involves using of conventional methods (decomposition and expert estimates. As a unit of measurement assumes to use points and rating scale with the maximum score a hundred points. A complex value, which is evaluated at one hundred points, is a result of the program. It is critically important in the process of current and final evaluation of the program.

Model-based control strategies for systems with constraints of the program type

Science.gov (United States)

Jarzębowska, Elżbieta

2006-08-01

The paper presents a model-based tracking control strategy for constrained mechanical systems. Constraints we consider can be material and non-material ones referred to as program constraints. The program constraint equations represent tasks put upon system motions and they can be differential equations of orders higher than one or two, and be non-integrable. The tracking control strategy relies upon two dynamic models: a reference model, which is a dynamic model of a system with arbitrary order differential constraints and a dynamic control model. The reference model serves as a motion planner, which generates inputs to the dynamic control model. It is based upon a generalized program motion equations (GPME) method. The method enables to combine material and program constraints and merge them both into the motion equations. Lagrange's equations with multipliers are the peculiar case of the GPME, since they can be applied to systems with constraints of first orders. Our tracking strategy referred to as a model reference program motion tracking control strategy enables tracking of any program motion predefined by the program constraints. It extends the "trajectory tracking" to the "program motion tracking". We also demonstrate that our tracking strategy can be extended to a hybrid program motion/force tracking.

2018-01-01

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 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.

Let’s sing our heroes: A comparison of biographical series for children in Kenya and South Africa

Directory of Open Access Journals (Sweden)

C.K. Muriungi

2004-07-01

Full Text Available In this article two series of biographies written for children, and dealing with prominent personalities in Kenya and South Africa, are compared. In the line of argumentation developed the aim is to examine the main features in these biographies, and to indicate the importance of biographies in the general field of children’s literature. By examining a sample text from each series the specific ways in which the authors mould these personalities into heroes of their countries are scrutinised. Furthermore the way in which gender is represented in the two series is also examined and it is argued that both men and women form part of any country’s gallery of heroes. Underlying the main argument of the article is the contention that biographies are important in perpetuating the stories of the two countries’ heroes: also in teaching the history of each country to the young. A general motif of hard work resonates in these works, and therefore it is asserted that individuals’ biographies can be used as anecdotes to communicate with and to inspire and encourage young readers. The authors of the biographies actually intervene by presenting children with role models. Furthermore these role models are not abstract fictional characters but real human beings who made great sacrifices for their countries – people with whom children are thus able to identify.

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

2014-07-01

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.

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.

Scientific biography, cognitive deficits, and laboratory practice. James McKeen Cattell and early American experimental psychology, 1880-1904.

Sokal, Michael M

2010-09-01

Despite widespread interest in individual life histories, few biographies of scientists make use of insights derived from psychology, another discipline that studies people, their thoughts, and their actions. This essay argues that recent theoretical work in psychology and tools developed for clinical psychological practice can help biographical historians of science create and present fuller portraits of their subjects' characters and temperaments and more nuanced analyses of how these traits helped shape their subjects' scientific work. To illustrate this thesis, the essay examines the early career of James McKeen Cattell--an influential late nineteenth- and early twentieth-century experimental psychologist--through a lens offered by psychology and argues that Cattell's actual laboratory practices derived from an "accommodation" to a long-standing "cognitive deficit." These practices in turn enabled Cattell to achieve more precise experimental results than could any of his contemporaries; and their students readily adopted them, along with their behavioral implications. The essay concludes that, in some ways, American psychology's early twentieth-century move toward a behavioral understanding of psychological phenomena can be traced to Cattell's personal cognitive deficit. It closes by reviewing several "remaining general questions" that this thesis suggests.

Wu, Juan; Ge, Xueqian

Linear programming is an important branch of operational research and it is a mathematical method to assist the people to carry out scientific management. GAMS is an advanced simulation and optimization modeling language and it will combine a large number of complex mathematical programming, such as linear programming LP, nonlinear programming NLP, MIP and other mixed-integer programming with the system simulation. In this paper, based on the linear programming model, the optimized investment decision-making of generation is simulated and analyzed. At last, the optimal installed capacity of power plants and the final total cost are got, which provides the rational decision-making basis for optimized investments.

GIGMF - A statistical model program

International Nuclear Information System (INIS)

Vladuca, G.; Deberth, C.

1978-01-01

The program GIGMF computes the differential and integrated statistical model cross sections for the reactions proceeding through a compound nuclear stage. The computational method is based on the Hauser-Feshbach-Wolfenstein theory, modified to include the modern version of Tepel et al. Although the program was written for a PDP-15 computer, with 16K high speed memory, many reaction channels can be taken into account with the following restrictions: the pro ectile spin must be less than 2, the maximum spin momenta of the compound nucleus can not be greater than 10. These restrictions are due solely to the storage allotments and may be easily relaxed. The energy of the impinging particle, the target and projectile masses, the spin and paritjes of the projectile, target, emergent and residual nuclei the maximum orbital momentum and transmission coefficients for each reaction channel are the input parameters of the program.

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

Mo LI,Ping GUO,Liudong ZHANG,Chenglong ZHANG

2016-03-01

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

Reynolds, Clare M; Vickers, Mark H

2018-01-01

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.

Modelling and Formal Verification of Timing Aspects in Large PLC Programs

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

2014-01-01

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.

The ASC Sequoia Programming Model

Seager, M

In the late 1980's and early 1990's, Lawrence Livermore National Laboratory was deeply engrossed in determining the next generation programming model for the Integrated Design Codes (IDC) beyond vectorization for the Cray 1s series of computers. The vector model, developed in mid 1970's first for the CDC 7600 and later extended from stack based vector operation to memory to memory operations for the Cray 1s, lasted approximately 20 years (See Slide 5). The Cray vector era was deemed an extremely long lived era as it allowed vector codes to be developed over time (the Cray 1s were faster in scalar mode than the CDC 7600) with vector unit utilization increasing incrementally over time. The other attributes of the Cray vector era at LLNL were that we developed, supported and maintained the Operating System (LTSS and later NLTSS), communications protocols (LINCS), Compilers (Civic Fortran77 and Model), operating system tools (e.g., batch system, job control scripting, loaders, debuggers, editors, graphics utilities, you name it) and math and highly machine optimized libraries (e.g., SLATEC, and STACKLIB). Although LTSS was adopted by Cray for early system generations, they later developed COS and UNICOS operating systems and environment on their own. In the late 1970s and early 1980s two trends appeared that made the Cray vector programming model (described above including both the hardware and system software aspects) seem potentially dated and slated for major revision. These trends were the appearance of low cost CMOS microprocessors and their attendant, departmental and mini-computers and later workstations and personal computers. With the wide spread adoption of Unix in the early 1980s, it appeared that LLNL (and the other DOE Labs) would be left out of the mainstream of computing without a rapid transition to these 'Killer Micros' and modern OS and tools environments. The other interesting advance in the period is that systems were being

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

2009-04-01

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.

Dependent-Chance Programming Models for Capital Budgeting in Fuzzy Environments

Institute of Scientific and Technical Information of China (English)

LIANG Rui; GAO Jinwu

2008-01-01

Capital budgeting is concerned with maximizing the total net profit subject to budget constraints by selecting an appropriate combination of projects. This paper presents chance maximizing models for capital budgeting with fuzzy input data and multiple conflicting objectives. When the decision maker sets a prospec-tive profit level and wants to maximize the chances of the total profit achieving the prospective profit level, a fuzzy dependent-chance programming model, a fuzzy multi-objective dependent-chance programming model, and a fuzzy goal dependent-chance programming model are used to formulate the fuzzy capital budgeting problem. A fuzzy simulation based genetic algorithm is used to solve these models. Numerical examples are provided to illustrate the effectiveness of the simulation-based genetic algorithm and the po-tential applications of these models.

Devil is in the details: Using logic models to investigate program process.

Science.gov (United States)

Peyton, David J; Scicchitano, Michael

2017-12-01

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.

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.

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

2004-01-01

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 sobel.sas, 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.

Gstat: a program for geostatistical modelling, prediction and simulation

Science.gov (United States)

Pebesma, Edzer J.; Wesseling, Cees G.

1998-01-01

Gstat is a computer program for variogram modelling, and geostatistical prediction and simulation. It provides a generic implementation of the multivariable linear model with trends modelled as a linear function of coordinate polynomials or of user-defined base functions, and independent or dependent, geostatistically modelled, residuals. Simulation in gstat comprises conditional or unconditional (multi-) Gaussian sequential simulation of point values or block averages, or (multi-) indicator sequential simulation. Besides many of the popular options found in other geostatistical software packages, gstat offers the unique combination of (i) an interactive user interface for modelling variograms and generalized covariances (residual variograms), that uses the device-independent plotting program gnuplot for graphical display, (ii) support for several ascii and binary data and map file formats for input and output, (iii) a concise, intuitive and flexible command language, (iv) user customization of program defaults, (v) no built-in limits, and (vi) free, portable ANSI-C source code. This paper describes the class of problems gstat can solve, and addresses aspects of efficiency and implementation, managing geostatistical projects, and relevant technical details.

LDA-Based Unified Topic Modeling for Similar TV User Grouping and TV Program Recommendation.

Science.gov (United States)

Pyo, Shinjee; Kim, Eunhui; Kim, Munchurl

2015-08-01

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

2014-01-01

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.

Full Text Available Publication of Russian translations by V.G. Tiesenhausen of extracts from Arabic sources on the history of the Golden Horde was a breakthrough in this research topic. Thanks to the work of V.G. Tiesenhausen, Russian historical school has become one of the leading research schools and remains such to the present day. However, the work of V.G. Tiesenhausen does not exhaust the entire storehouse of medieval historical and geographical literature in the Arabic language, as he states in the preface to his work. Proof of this is the fact that in voluminous work of V.G. Tiesenhausen we practically do not meet materials from the writings of historians dealing with the narrative biographies, although their works contain very valuable information about the history of the Golden Horde. As examples of such works, we can name the following: 1 al-Safadi (696 AH / 1297 – 764 AH / 1363, “Al-Wafi bi al-vafiyat” (الوافي بالوفياب أو تاريخ الصفدي (Complete Collection of Biographies of Deceased Persons or the History of al-Safadi; 2 al-Safadi (696 AH / 1297 – 764 AH / 1363, (أعيان العصر وأعوان النصر (Outstanding Personalities of this century, and the Champions of Victory; 3 al-Kutubi Muhamamd Shakir (d. 764 AH, (فوات الوفيات و الذيل عليها (Biographies of Deceased Persons not included (in the collection of Ibn Hallikan (608 AH / 1211 – 681 AH / 1282, and addition to them; 4 (al-Maqrisi Taqi al-Din (d. 845 AH, (كتاب المقفّى الكبير (Great Rhymed Book; 5 al-Asqalani Ibn Najar (d. 852 AH (الدرر الكامنة في أعيان المائة الثامنة (Hidden Pearls in a Biography of Outstanding Persons of the eighth century of Hijra; 6 Ibn Taghribirdi (813–874 AH (المنهل الصافي المستوفي بعد الوافي (Pure Completing Source after the “Full”.

2018-01-01

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.

The Model was updated to incorporate cost data from the most recent US planetary flight projects and extensively revised to more accurately capture the information in the historical cost data base. This data base is comprised of the historical cost data for 13 unmanned lunar and planetary flight programs. The revision was made with a two fold objective: to increase the flexibility of the model in its ability to deal with the broad scope of scenarios under consideration for future missions, and to maintain and possibly improve upon the confidence in the model's capabilities with an expected accuracy of 20%. The Model development included a labor/cost proxy analysis, selection of the functional forms of the estimating relationships, and test statistics. An analysis of the Model is discussed and two sample applications of the cost model are presented.

A model surveillance program is presented based on regulatory experience. The program consists of three phases: Program Delineation, Data Acquistion and Data Analysis. Each phase is described in terms of key quality assurance elements and some current philosophies is the United States Licensing Program. Other topics include the application of these ideas to test equipment used in the surveillance progam and audits of the established program. Program Delineation discusses the establishment of administrative controls for organization and the description of responsibilities using the 'Program Coordinator' concept, with assistance from Data Acquisition and Analysis Teams. Ideas regarding frequency of surveillance testing are also presented. The Data Acquisition Phase discusses various methods for acquiring data including operator observations, test procedures, operator logs, and computer output, for trending equipment performance. The Data Analysis Phase discusses the process for drawing conclusions regarding component/equipment service life, proper application, and generic problems through the use of trend analysis and failure rate data.

Wagh, Aditi; Wilensky, Uri

2018-04-01

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.

A model of nonparticipation in alcohol treatment programs.

Burton, T L; Williamson, D L

1997-01-01

Why do the vast majority of those who suffer harm from drinking fail to obtain treatment? Based on a review of research literature and educational and treatment program materials, a model of nonparticipation in treatment is proposed whereby particular population groups are separated out according to whether or not they exhibit specified characteristics related to both harm from drinking and attitudes towards treatment. Eleven groups have been identified in the model, each of which has different reasons for failing to seek and/or obtain treatment. It is suggested that differing educational program messages should be sent to each group. While the model does not purport to be wholly inclusive of all nonparticipation, it offers a basis for addressing the variety of disparate groups that suffer harm from drinking but do not obtain treatment.

Understanding science teacher enhancement programs: Essential components and a model

Science.gov (United States)

Spiegel, Samuel Albert

Researchers and practioners alike recognize that "the national goal that every child in the United States has access to high-quality school education in science and mathematics cannot be realized without the availability of effective professional development of teachers" (Hewson, 1997, p. 16). Further, there is a plethora of reports calling for the improvement of professional development efforts (Guskey & Huberman, 1995; Kyle, 1995; Loucks-Horsley, Hewson, Love, & Stiles, 1997). In this study I analyze a successful 3-year teacher enhancement program, one form of professional development, to: (1) identify essential components of an effective teacher enhancement program; and (2) create a model to identify and articulate the critical issues in designing, implementing, and evaluating teacher enhancement programs. Five primary sources of information were converted into data: (1) exit questionnaires, (2) exit surveys, (3) exit interview transcripts, (4) focus group transcripts, and (5) other artifacts. Additionally, a focus group was used to conduct member checks. Data were analyzed in an iterative process which led to the development of the list of essential components. The Components are categorized by three organizers: Structure (e.g., science research experience, a mediator throughout the program), Context (e.g., intensity, collaboration), and Participant Interpretation (e.g., perceived to be "safe" to examine personal beliefs and practices, actively engaged). The model is based on: (1) a 4-year study of a successful teacher enhancement program; (2) an analysis of professional development efforts reported in the literature; and (3) reflective discussions with implementors, evaluators, and participants of professional development programs. The model consists of three perspectives, cognitive, symbolic interaction, and organizational, representing different viewpoints from which to consider issues relevant to the success of a teacher enhancement program.

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

A Model of Computation for Bit-Level Concurrent Computing and Programming: APEC

Science.gov (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.

Full Text Available Ad Hoc wireless network faces more security threats than traditional network due to its P2P system structure and the limited node resources. In recent years, malicious program has become one of the most important researches on international network security and information security. The research of malicious programs on wireless network has become a new research hotspot in the field of malicious programs. This paper first analyzed the Ad Hoc network system structure, security threats, the common classification of malicious programs and the bionic propagation model. Then starting from the differential equations of the SEIR virus propagation model, the question caused by introducing the SEIR virus propagation model in Ad Hoc wireless network was analyzed. This paper improved the malicious program propagation model through introducing the network topology features and concepts such as immunization delay, and designed an improved algorithm combined with the dynamic evolution of malware propagation process. Considering of the network virus propagation characteristics, network characteristics and immunization strategy to improve simulation model experiment analysis, the experimental results show that both the immunization strategy and the degrees of node can affect the propagation of malicious program.

Demand response modeling considering Interruptible/Curtailable loads and capacity market programs

International Nuclear Information System (INIS)

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

2010-01-01

Recently, a massive focus has been made on demand response (DR) programs, aimed to electricity price reduction, transmission lines congestion resolving, security enhancement and improvement of market liquidity. Basically, demand response programs are divided into two main categories namely, incentive-based programs and time-based programs. The focus of this paper is on Interruptible/Curtailable service (I/C) and capacity market programs (CAP), which are incentive-based demand response programs including penalties for customers in case of no responding to load reduction. First, by using the concept of price elasticity of demand and customer benefit function, economic model of above mentioned programs is developed. The proposed model helps the independent system operator (ISO) to identify and employ relevant DR program which both improves the characteristics of the load curve and also be welcome by customers. To evaluate the performance of the model, simulation study has been conducted using the load curve of the peak day of the Iranian power system grid in 2007. In the numerical study section, the impact of these programs on load shape and load level, and benefit of customers as well as reduction of energy consumption are shown. In addition, by using strategy success indices the results of simulation studies for different scenarios are analyzed and investigated for determination of the scenarios priority. (author)

Modeling and prioritizing demand response programs in power markets

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

2010-01-01

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)

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.

A simulation model is developed to value energy efficiency improvement programs in Louisiana proposed to be delivered through a Public Benefits Fund. A uniform 1 mill/kW h non-bypassable surcharge on the electric rates of all electricity users is proposed to be distributed for low-income bill assistance, low-income weatherization, and energy efficiency programs across the residential and commercial sector of Louisiana. The economic and environmental impact of the energy improvement programs is coupled to a stochastic linear program to specify the resource allocation subject to policy and system constraints. The model is illustrated through a realistic policy scenario. (Author)

Transforming PLC Programs into Formal Models for Verification Purposes

CERN Document Server

Darvas, D; Blanco, E

2013-01-01

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.

Bourbaki's structure theory in the problem of complex systems simulation models synthesis and model-oriented programming

Science.gov (United States)

Brodsky, Yu. I.

2015-01-01

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.

2013-04-01

Introduction and diffusion of new disease management programs in healthcare is usually slow, but active theory-driven implementation seems to outperform other implementation strategies. However, we have only scarce evidence on the feasibility and real effect of such strategies in complex primary care settings where municipalities, general practitioners and hospitals should work together. The Central Denmark Region recently implemented a disease management program for chronic obstructive pulmonary disease (COPD) which presented an opportunity to test an active implementation model against the usual implementation model. The aim of the present paper is to describe the development of an active implementation model using the Medical Research Council's model for complex interventions and the Chronic Care Model. We used the Medical Research Council's five-stage model for developing complex interventions to design an implementation model for a disease management program for COPD. First, literature on implementing change in general practice was scrutinised and empirical knowledge was assessed for suitability. In phase I, the intervention was developed; and in phases II and III, it was tested in a block- and cluster-randomised study. In phase IV, we evaluated the feasibility for others to use our active implementation model. The Chronic Care Model was identified as a model for designing efficient implementation elements. These elements were combined into a multifaceted intervention, and a timeline for the trial in a randomised study was decided upon in accordance with the five stages in the Medical Research Council's model; this was captured in a PaTPlot, which allowed us to focus on the structure and the timing of the intervention. The implementation strategies identified as efficient were use of the Breakthrough Series, academic detailing, provision of patient material and meetings between providers. The active implementation model was tested in a randomised trial

Eukaryotes have long been reported to show temporal programs of replication, different portions of the genome being replicated at different times in S phase, with the added possibility of developmentally regulated changes in this pattern depending on species and cell type. Unicellular model organisms, primarily the budding yeast Saccharomyces cerevisiae, have been central to our current understanding of the mechanisms underlying the regulation of replication origins and the temporal program of replication in particular. But what exactly is a temporal program of replication, and how might it arise? In this article, we explore this question, drawing again on the wealth of experimental information in unicellular model organisms.

A goal programming model for environmental policy analysis: Application to Spain

International Nuclear Information System (INIS)

San Cristóbal, José Ramón

2012-01-01

Sustainable development has become an important part of international and national approaches to integrate economic, environmental, social and ethical considerations so that a good quality of life can be enjoyed by current and future generations for as long as possible. However, nowadays sustainable development is threatened by industrial pollution emissions which cause serious environmental problems. Due to a lack of adequate quantitative models for environmental policy analysis, there is a strong need for analytical models in order to know the effects of environmental policies. In the present paper, a goal programming model, based on an environmental/input–output linear programming model, is developed and applied to the Spanish economy. The model combines relations between economic, energy, social and environmental effects, providing valuable information for policy-makers in order to define and examine the different goals that must be implemented to reach sustainability. - Highlights: ► In this paper a goal programming model is developed. ► The model considers environmental, energy, social and economic goals. ► The model shows the effects of a reduction in greenhouse gasses emission and energy requirements. ► The model is applied to the Spanish economy.

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

2014-01-01

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.

An approach for evaluating utility-financed energy conservation programs. The economic welfare model

Energy Technology Data Exchange (ETDEWEB)

Costello, K W; Galen, P S

1985-09-01

The main objective of this paper is to illustrate how the economic welfare model may be used to measure the economic efficiency effects of utility-financed energy conservation programs. The economic welfare model is the theoretical structure that was used in this paper to develop a cost/benefit test. This test defines the net benefit of a conservation program as the change in the sum of consumer and producer surplus. The authors advocate the operation of the proposed cost/benefit model as a screening tool to eliminate from more detailed review those programs where the expected net benefits are less than zero. The paper presents estimates of the net benefit derived from different specified cost/benefit models for four illustrative pilot programs. These models are representative of those which have been applied or are under review by utilities and public utility commissions. From the numerical results, it is shown that net benefit is greatly affected by the assumptions made about the nature of welfare gains to program participants. The main conclusion that emerges from the numerical results is that the selection of a cost/benefit model is a crucial element in evaluating utility-financed energy conservation programs. The paper also briefly addresses some of the major unresolved issues in utility-financed energy conservation programs. 2 figs., 3 tabs., 10 refs. (A.V.)

User Guide and Documentation for Five MODFLOW Ground-Water Modeling Utility Programs

Science.gov (United States)

Banta, Edward R.; Paschke, Suzanne S.; Litke, David W.

2008-01-01

This report documents five utility programs designed for use in conjunction with ground-water flow models developed with the U.S. Geological Survey's MODFLOW ground-water modeling program. One program extracts calculated flow values from one model for use as input to another model. The other four programs extract model input or output arrays from one model and make them available in a form that can be used to generate an ArcGIS raster data set. The resulting raster data sets may be useful for visual display of the data or for further geographic data processing. The utility program GRID2GRIDFLOW reads a MODFLOW binary output file of cell-by-cell flow terms for one (source) model grid and converts the flow values to input flow values for a different (target) model grid. The spatial and temporal discretization of the two models may differ. The four other utilities extract selected 2-dimensional data arrays in MODFLOW input and output files and write them to text files that can be imported into an ArcGIS geographic information system raster format. These four utilities require that the model cells be square and aligned with the projected coordinate system in which the model grid is defined. The four raster-conversion utilities are * CBC2RASTER, which extracts selected stress-package flow data from a MODFLOW binary output file of cell-by-cell flows; * DIS2RASTER, which extracts cell-elevation data from a MODFLOW Discretization file; * MFBIN2RASTER, which extracts array data from a MODFLOW binary output file of head or drawdown; and * MULT2RASTER, which extracts array data from a MODFLOW Multiplier file.

To evaluate the potential annual net cost savings of implementing an ICU early rehabilitation program. Using data from existing publications and actual experience with an early rehabilitation program in the Johns Hopkins Hospital Medical ICU, we developed a model of net financial savings/costs and presented results for ICUs with 200, 600, 900, and 2,000 annual admissions, accounting for both conservative- and best-case scenarios. Our example scenario provided a projected financial analysis of the Johns Hopkins Medical ICU early rehabilitation program, with 900 admissions per year, using actual reductions in length of stay achieved by this program. U.S.-based adult ICUs. Financial modeling of the introduction of an ICU early rehabilitation program. Net cost savings generated in our example scenario, with 900 annual admissions and actual length of stay reductions of 22% and 19% for the ICU and floor, respectively, were $817,836. Sensitivity analyses, which used conservative- and best-case scenarios for length of stay reductions and varied the per-day ICU and floor costs, across ICUs with 200-2,000 annual admissions, yielded financial projections ranging from -$87,611 (net cost) to $3,763,149 (net savings). Of the 24 scenarios included in these sensitivity analyses, 20 (83%) demonstrated net savings, with a relatively small net cost occurring in the remaining four scenarios, mostly when simultaneously combining the most conservative assumptions. A financial model, based on actual experience and published data, projects that investment in an ICU early rehabilitation program can generate net financial savings for U.S. hospitals. Even under the most conservative assumptions, the projected net cost of implementing such a program is modest relative to the substantial improvements in patient outcomes demonstrated by ICU early rehabilitation programs.

Fournier, D.F. Jr.

1993-01-01

The Model Low Energy Installation Program is a demonstration of an installation-wide, comprehensive energy conservation program that meets the Department of Defense (DoD) energy management goals of reducing energy usage and costs by at least 20%. It employs the required strategies for meeting these goals, quantifies the environmental compliance benefits resulting from energy conservation and serves as a prototype for DoD wide application. This project will develop both analysis tools and implementation procedures as well as demonstrate the effectiveness of a comprehensive, coordinated energy conservation program based on state-of-the-art technologies. A military installation is in reality a small to medium sized city. It generally has a complete utilities infrastructure including water supply and distribution, sewage collection and treatment, electrical supply and distribution, central heating and cooling plants with thermal distribution, and a natural gas distribution system. These utilities are quite extensive and actually consume about 10-15% of the energy on the facility not counting the energy going into the central plants

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.

Full Text Available Purpose. To improve simulation and design of Automatic Control Systems in the SPICE-compatible programs and to obtain separate economic and universal macromodels of PWM controller. Development of an PWM controller economical macromodel for the study of automatic control systems (ACS in computer-aided design (ECAD  programs, which does not generate algorithmic failures in comparison with the existing models of PWM. Findings. Analysis of SPICE-family applications’ mathematical basis allowed to classifying existing models of PWM-controllers, defining their suitability for ACS simulation. The criteria for the synthesis of new models have been defined. For the SPICE 3G algorithms, the Switch and Averaged models based on behavioral elements has been developed. Universal and economical PWM controller macromodel based on the simple algorithm for determining the output signal with minimum numbers of input parameters has been designed. For the Automated Measuring magnetic susceptibility System, the macromodel of quasi-PWM signal generator have been designed, which is used in the compensation subsystem. This model is different from the existing ones: it synthesizes the staircase output signal instead the pulse one, thus, there is direct control of the amplitude of the output signal, which is taken averaged. The adequacy of the models is confirmed as comparison of the simulation results during investigations of the model already existing in the SPICE program, as well as the results of experiments with real ACS. The modeling of the PWM controller was carried out on the basis of behavioral elements from the ECAD library, simulation (solution of algebra-differential equations systems with programming elements is based on SPICE algorithms. The object of the study was the simulation process of ACS with the pulse-width principle of adjusting the output value. The subject of the research are the models of PWM controllers. Originality.

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.

A Programming Model for Massive Data Parallelism with Data Dependencies

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

2009-01-01

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

2014-01-01

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.

Solving a bi-objective mathematical programming model for bloodmobiles location routing problem

Directory of Open Access Journals (Sweden)

Masoud Rabbani

2017-01-01

Full Text Available Perishability of platelets, uncertainty of donors’ arrival and conflicting views in platelet supply chain have made platelet supply chain planning a problematic issue. In this paper, mobile blood collection system for platelet production is investigated. Two mathematical models are presented to cover the bloodmobile collection planning problem. The first model is a multi-objective fuzzy mathematical programming in which the bloodmobiles locations are considered with the aim of maximizing potential amount of blood collection and minimizing the operational cost. The second model is a vehicle routing problem with time windows which studies the shuttles routing problem. To tackle the first model, it is reformulated as a crisp multi objective linear programming model and then solved through a fuzzy multi objective programming approach. Several sensitivity analysis are conducted on important parameters to demonstrate the applicability of the proposed model. The proposed model is then solved by using a tailored Simulated Annealing (SA algorithm. The numerical results demonstrate promising efficiency of the proposed solution method.

2009-01-01

Full Text Available The volatility is a crucial variable in option pricing and hedging strategies. The aim of this paper is to provide some initial evidence of the empirical relevance of genetic programming to volatility's forecasting. By using real data from S&P500 index options, the genetic programming's ability to forecast Black and Scholes-implied volatility is compared between time series samples and moneyness-time to maturity classes. Total and out-of-sample mean squared errors are used as forecasting's performance measures. Comparisons reveal that the time series model seems to be more accurate in forecasting-implied volatility than moneyness time to maturity models. Overall, results are strongly encouraging and suggest that the genetic programming approach works well in solving financial problems.

Xu, Zeshui S; Chen, Jian

2008-10-01

Group decision making with preference information on alternatives is an interesting and important research topic which has been receiving more and more attention in recent years. The purpose of this paper is to investigate multiple-attribute group decision-making (MAGDM) problems with distinct uncertain preference structures. We develop some linear-programming models for dealing with the MAGDM problems, where the information about attribute weights is incomplete, and the decision makers have their preferences on alternatives. The provided preference information can be represented in the following three distinct uncertain preference structures: 1) interval utility values; 2) interval fuzzy preference relations; and 3) interval multiplicative preference relations. We first establish some linear-programming models based on decision matrix and each of the distinct uncertain preference structures and, then, develop some linear-programming models to integrate all three structures of subjective uncertain preference information provided by the decision makers and the objective information depicted in the decision matrix. Furthermore, we propose a simple and straightforward approach in ranking and selecting the given alternatives. It is worth pointing out that the developed models can also be used to deal with the situations where the three distinct uncertain preference structures are reduced to the traditional ones, i.e., utility values, fuzzy preference relations, and multiplicative preference relations. Finally, we use a practical example to illustrate in detail the calculation process of the developed approach.

2016-01-01

Tetrahedral-mesh geometries can be used in the MCNP code, but the MCNP code accepts only the geometry in the Abaqus input file format; hence, the existing tetrahedral-mesh models first need to be converted to the Abacus input file format to be used in the MCNP code. In the present study, we developed a simple but useful computer program, TET_2MCNP, for converting TetGen-generated tetrahedral-mesh models to the Abacus input file format. TET_2MCNP is written in C++ and contains two components: one for converting a TetGen output file to the Abacus input file and the other for the reverse conversion process. The TET_2MCP program also produces an MCNP input file. Further, the program provides some MCNP-specific functions: the maximum number of elements (i.e., tetrahedrons) per part can be limited, and the material density of each element can be transferred to the MCNP input file. To test the developed program, two tetrahedral-mesh models were generated using TetGen and converted to the Abaqus input file format using TET_2MCNP. Subsequently, the converted files were used in the MCNP code to calculate the object- and organ-averaged absorbed dose in the sphere and phantom, respectively. The results show that the converted models provide, within statistical uncertainties, identical dose values to those obtained using the PHITS code, which uses the original tetrahedral-mesh models produced by the TetGen program. The results show that the developed program can successfully convert TetGen tetrahedral-mesh models to Abacus input files. In the present study, we have developed a computer program, TET_2MCNP, which can be used to convert TetGen-generated tetrahedral-mesh models to the Abaqus input file format for use in the MCNP code. We believe this program will be used by many MCNP users for implementing complex tetrahedral-mesh models, including computational human phantoms, in the MCNP code

Lee, S.K.

1993-01-01

An effort is currently underway at NASA and the Department of Energy (DOE) to develop an accurate model for predicting nuclear thermal propulsion (NTP) system performance. The objective of the effort is to develop several levels of computer programs which vary in detail and complexity according to user's needs. The current focus is on the Level 1 steady-state, parametric system model. This system model will combine a general fluid mechanics program, SAFSIM, with the ability to analyze turbines, pumps, nozzles, and reactor physics. SAFSIM (System Analysis Flow SIMulator) is a FORTRAN computer program that simulates integrated performance of systems involving fluid mechanics, heat transfer, and reactor dynamics. SAFSIM has the versatility to allow simulation of almost any system, including a nuclear reactor system. The focus of this paper is the validation of SAFSIM's capabilities as a base computational engine for a nuclear thermal propulsion system model. Validation is being accomplished by modeling of a nuclear engine test using SAFSIM and comparing the results to known experimental data

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)

2017-08-01

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.

Original article Rehabilitation model program for seriously ill patients

Adrienne Kegye

2014-10-01

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

Conceptual models are an integral facet of long-term monitoring programs. Proposed linkages between drivers, stressors, and ecological indicators are identified within the conceptual model of most mandated programs. We empirically evaluate a conceptual model developed for a regional aquatic and riparian monitoring program using causal models (i.e., Bayesian path analysis). We assess whether data gathered for regional status and trend estimation can also provide insights on why a stream may deviate from reference conditions. We target the hypothesized causal pathways for how anthropogenic drivers of road density, percent grazing, and percent forest within a catchment affect instream biological condition. We found instream temperature and fine sediments in arid sites and only fine sediments in mesic sites accounted for a significant portion of the maximum possible variation explainable in biological condition among managed sites. However, the biological significance of the direct effects of anthropogenic drivers on instream temperature and fine sediments were minimal or not detected. Consequently, there was weak to no biological support for causal pathways related to anthropogenic drivers’ impact on biological condition. With weak biological and statistical effect sizes, ignoring environmental contextual variables and covariates that explain natural heterogeneity would have resulted in no evidence of human impacts on biological integrity in some instances. For programs targeting the effects of anthropogenic activities, it is imperative to identify both land use practices and mechanisms that have led to degraded conditions (i.e., moving beyond simple status and trend estimation). Our empirical evaluation of the conceptual model underpinning the long-term monitoring program provided an opportunity for learning and, consequently, we discuss survey design elements that require modification to achieve question driven monitoring, a necessary step in the practice of

Digital game-based learning (DGBL) makes use of the entertaining power of digital games for educational purposes. Effectiveness assessment of DGBL programs has been underexplored and no attempt has been made to simultaneously model both important components of DGBL: learning attainment (ie, educational purposes of DGBL) and engagement of users (ie, entertaining power of DGBL) in evaluating program effectiveness. This study aimed to describe and evaluate an Internet-based DGBL program, Professor Gooley and the Flame of Mind, which promotes mental health to adolescents in a positive youth development approach. In particular, we investigated whether user engagement in the DGBL program could enhance their attainment on each of the learning constructs per DGBL module and subsequently enhance their mental health as measured by psychological well-being. Users were assessed on their attainment on each learning construct, psychological well-being, and engagement in each of the modules. One structural equation model was constructed for each DGBL module to model the effect of users' engagement and attainment on the learning construct on their psychological well-being. Of the 498 secondary school students that registered and participated from the first module of the DGBL program, 192 completed all 8 modules of the program. Results from structural equation modeling suggested that a higher extent of engagement in the program activities facilitated users' attainment on the learning constructs on most of the modules and in turn enhanced their psychological well-being after controlling for users' initial psychological well-being and initial attainment on the constructs. This study provided evidence that Internet intervention for mental health, implemented with the technologies and digital innovations of DGBL, could enhance youth mental health. Structural equation modeling is a promising approach in evaluating the effectiveness of DGBL programs.

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

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

A Compromise Programming Model for Highway Maintenance Resources Allocation Problem

Directory of Open Access Journals (Sweden)

Hui Xiong

2012-01-01

Full Text Available This paper formulates a bilevel compromise programming model for allocating resources between pavement and bridge deck maintenances. The first level of the model aims to solve the resource allocation problems for pavement management and bridge deck maintenance, without considering resource sharing between them. At the second level, the model uses the results from the first step as an input and generates the final solution to the resource-sharing problem. To solve the model, the paper applies genetic algorithms to search for the optimal solution. We use a combination of two digits to represent different maintenance types. Results of numerical examples show that the conditions of both pavements and bridge decks are improved significantly by applying compromise programming, rather than conventional methods. Resources are also utilized more efficiently when the proposed method is applied.

2017-02-01

With the increasing data size in materials science, existing programming models no longer satisfy the application requirements. MapReduce is a programming model that enables the easy development of scalable parallel applications to process big data on cloud computing systems. However, this model does not directly support the processing of multiple related data, and the processing performance does not reflect the advantages of cloud computing. To enhance the capability of workflow applications in material data processing, we defined a programming model for material cloud applications that supports multiple different Map and Reduce functions running concurrently based on hybrid share-memory BSP called MaMR. An optimized data sharing strategy to supply the shared data to the different Map and Reduce stages was also designed. We added a new merge phase to MapReduce that can efficiently merge data from the map and reduce modules. Experiments showed that the model and framework present effective performance improvements compared to previous work.

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

Directory of Open Access Journals (Sweden)

V. Charles

2011-01-01

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.

The Father Friendly Initiative within Families: Using a logic model to develop program theory for a father support program.

Science.gov (United States)

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

2015-10-01

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.

There is a rich history in using program theories and logic models (PT/LM) for evaluation, monitoring, and program refinement in a variety of fields, such as health care, social and education programs. The use of these tools to evaluate and improve energy efficiency programs has been growing over the last 5-7 years. This paper provides an overview of the state-of-the-art methods of logic model development, with analysis that significantly contributed to: Assessing the logic behind how the program expects to be able to meets its ultimate goals, including the 'who', the 'how', and through what mechanism. In doing so, gaps and questions that still need to be addressed can be identified. Identifying and prioritize the indicators that should be measured to evaluate the program and program theory. Determining key researchable questions that need to be answered by evaluation/research, to assess whether the mechanism assumed to cause the changes in actions, attitudes, behaviours, and business practices is workable and efficient. Also will assess the validity in the program logic and the likelihood that the program can accomplish its ultimate goals. Incorporating analysis of prior like programs and social science theories in a framework to identify opportunities for potential program refinements. The paper provides an overview of the tools, techniques and references, and uses as example the energy efficiency program analysis conducted for the New York State Energy Research and Development Authority's (NYSERDA) New York ENERGY $MART SM programs

A Collective Case Study of Secondary Students' Model-Based Inquiry on Natural Selection through Programming in an Agent-Based Modeling Environment

Xiang, Lin

This is a collective case study seeking to develop detailed descriptions of how programming an agent-based simulation influences a group of 8 th grade students' model-based inquiry (MBI) by examining students' agent-based programmable modeling (ABPM) processes and the learning outcomes. The context of the present study was a biology unit on natural selection implemented in a charter school of a major California city during spring semester of 2009. Eight 8th grade students, two boys and six girls, participated in this study. All of them were low socioeconomic status (SES). English was a second language for all of them, but they had been identified as fluent English speakers at least a year before the study. None of them had learned either natural selection or programming before the study. The study spanned over 7 weeks and was comprised of two study phases. In phase one the subject students learned natural selection in science classroom and how to do programming in NetLogo, an ABPM tool, in a computer lab; in phase two, the subject students were asked to program a simulation of adaptation based on the natural selection model in NetLogo. Both qualitative and quantitative data were collected in this study. The data resources included (1) pre and post test questionnaire, (2) student in-class worksheet, (3) programming planning sheet, (4) code-conception matching sheet, (5) student NetLogo projects, (6) videotaped programming processes, (7) final interview, and (8) investigator's field notes. Both qualitative and quantitative approaches were applied to analyze the gathered data. The findings suggested that students made progress on understanding adaptation phenomena and natural selection at the end of ABPM-supported MBI learning but the progress was limited. These students still held some misconceptions in their conceptual models, such as the idea that animals need to "learn" to adapt into the environment. Besides, their models of natural selection appeared to be

Networked Timetable Stability Improvement Based on a Bilevel Optimization Programming Model

Directory of Open Access Journals (Sweden)

2014-01-01

Full Text Available Train timetable stability is the possibility to recover the status of the trains to serve as arranged according to the original timetable when the trains are disturbed. To improve the train timetable stability from the network perspective, the bilevel programming model is constructed, in which the upper level programming is to optimize the timetable stability on the network level and the lower is to improve the timetable stability on the dispatching railway segments. Timetable stability on the network level is defined with the variances of the utilization coefficients of the section capacity and station capacity. Weights of stations and sections are decided by the capacity index number and the degrees. The lower level programming focuses on the buffer time distribution plan of the trains operating on the sections and stations, taking the operating rules of the trains as constraints. A novel particle swarm algorithm is proposed and designed for the bilevel programming model. The computing case proves the feasibility of the model and the efficiency of the algorithm. The method outlined in this paper can be embedded in the networked train operation dispatching system.

Modelling the effects of U.S. ENERGY STARR appliance programs

2005-01-01

Numerous U.S. utilities and market transformation organizations have invested heavily in the ENERGY STAR program, designed to increase market penetration of energy-efficient products (e.g., home appliances, lighting products, windows). Major activities involve stimulating production and promotion of qualifying models, as well as stocking, sales support and financial incentives to customers-all of which entail considerable investments of public funds. Several studies have shown that customer awareness of ENERGY STAR has increased across the country, particularly where energy-efficiency programs have been most active. Furthermore, studies in regions with aggressive programs have shown that the market penetration of qualifying products has increased rapidly. Until recently, however, policy makers have lacked reliable studies that compare changes in market penetration across regions with and without programs while factoring out effects of demographic and other background factors (e.g., education, income, and climate). Also lacking have been attempts to assess whether heavy promotion of the ENERGY STAR brand with some appliances (e.g., clothes washers) has affected the market penetration of less-promoted qualifying appliances. In this paper, the authors address these issues, using a database of the market penetration of four major home appliances at national retailers in each of the individual states over a multi-year period, based on multivariate statistical models. Results include both analyses of the overall trend of market penetration (1998-2002) for the appliances considered and the incremental effects of the 2003 program. The results lead to recommendations regarding the design of programs supporting ENERGY STAR compliant appliances and the key components of those programs

Minakova, N.; Petrov, I.

2018-01-01

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.

Enhancement of weld failure and tube ejection model in PENTAP program

International Nuclear Information System (INIS)

Jung, Jaehoon; An, Sang Mo; Ha, Kwang Soon; Kim, Hwan Yeol

2014-01-01

The reactor vessel pressure, the debris mass, the debris temperature, and the component of material can have an effect on the penetration tube failure modes. Furthermore, these parameters are interrelated. There are some representative severe accident codes such as MELCOR, MAAP, and PENTAP program. MELCOR decides on a penetration tube failure by its failure temperature such as 1273K simply. MAAP considers all penetration failure modes and has the most advanced model for a penetration tube failure model. However, the validation work against the experimental data is very limited. PENTAP program which evaluates the possible penetration tube failure modes such as creep failure, weld failure, tube ejection, and a long term tube failure under given accident condition was developed by KAERI. The experiment for the tube ejection is being performed by KAERI. The temperature distribution and the ablation rate of both weld and lower vessel wall can be obtained through the experiment. This paper includes the updated calculation steps for the weld failure and the tube ejection modes of the PENTAP program to apply the experimental results. PENTAP program can evaluate the possible penetration tube failure modes. It still requires a large amount of efforts to increase the prediction of failure modes. Some calculation steps are necessary for applying the experimental and the numerical data in the PENTAP program. In this study, new calculation steps are added to PENTAP program to enhance the weld failure and tube ejection models using KAERI's experimental data which are the ablation rate and temperature distribution of weld and lower vessel wall

Tetrahedral-mesh geometries can be used in the MCNP code, but the MCNP code accepts only the geometry in the Abaqus input file format; hence, the existing tetrahedral-mesh models first need to be converted to the Abacus input file format to be used in the MCNP code. In the present study, we developed a simple but useful computer program, TET{sub 2}MCNP, for converting TetGen-generated tetrahedral-mesh models to the Abacus input file format. TET{sub 2}MCNP is written in C++ and contains two components: one for converting a TetGen output file to the Abacus input file and the other for the reverse conversion process. The TET{sub 2}MCP program also produces an MCNP input file. Further, the program provides some MCNP-specific functions: the maximum number of elements (i.e., tetrahedrons) per part can be limited, and the material density of each element can be transferred to the MCNP input file. To test the developed program, two tetrahedral-mesh models were generated using TetGen and converted to the Abaqus input file format using TET{sub 2}MCNP. Subsequently, the converted files were used in the MCNP code to calculate the object- and organ-averaged absorbed dose in the sphere and phantom, respectively. The results show that the converted models provide, within statistical uncertainties, identical dose values to those obtained using the PHITS code, which uses the original tetrahedral-mesh models produced by the TetGen program. The results show that the developed program can successfully convert TetGen tetrahedral-mesh models to Abacus input files. In the present study, we have developed a computer program, TET{sub 2}MCNP, which can be used to convert TetGen-generated tetrahedral-mesh models to the Abaqus input file format for use in the MCNP code. We believe this program will be used by many MCNP users for implementing complex tetrahedral-mesh models, including computational human phantoms, in the MCNP code.

Inexact Multistage Stochastic Chance Constrained Programming Model for Water Resources Management under Uncertainties

Directory of Open Access Journals (Sweden)

Hong Zhang

2017-01-01

Full Text Available In order to formulate water allocation schemes under uncertainties in the water resources management systems, an inexact multistage stochastic chance constrained programming (IMSCCP model is proposed. The model integrates stochastic chance constrained programming, multistage stochastic programming, and inexact stochastic programming within a general optimization framework to handle the uncertainties occurring in both constraints and objective. These uncertainties are expressed as probability distributions, interval with multiply distributed stochastic boundaries, dynamic features of the long-term water allocation plans, and so on. Compared with the existing inexact multistage stochastic programming, the IMSCCP can be used to assess more system risks and handle more complicated uncertainties in water resources management systems. The IMSCCP model is applied to a hypothetical case study of water resources management. In order to construct an approximate solution for the model, a hybrid algorithm, which incorporates stochastic simulation, back propagation neural network, and genetic algorithm, is proposed. The results show that the optimal value represents the maximal net system benefit achieved with a given confidence level under chance constraints, and the solutions provide optimal water allocation schemes to multiple users over a multiperiod planning horizon.

2017-08-01

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.

Mathematical models and algorithms for the computer program 'WOLF'

International Nuclear Information System (INIS)

Halbach, K.

1975-12-01

The computer program FLOW finds the nonrelativistic self- consistent set of two-dimensional ion trajectories and electric fields (including space charges from ions and electrons) for a given set of initial and boundary conditions for the particles and fields. The combination of FLOW with the optimization code PISA gives the program WOLF, which finds the shape of the emitter which is consistent with the plasma forming it, and in addition varies physical characteristics such as electrode position, shapes, and potentials so that some performance characteristics are optimized. The motivation for developing these programs was the desire to design optimum ion source extractor/accelerator systems in a systematic fashion. The purpose of this report is to explain and derive the mathematical models and algorithms which approximate the real physical processes. It serves primarily to document the computer programs. 10 figures

Identity as a narrative of autobiography

Directory of Open Access Journals (Sweden)

Luba Jakubowska

2010-12-01

Full Text Available This article is a proposal of identity research through its process and narrative character. As a starting point I present a definition of identity understood as the whole life process of finding identification. Next I present my own model of auto/biography-narrative research inspired by hermeneutic and phenomenological traditions of thinking about experiencing reality. I treat auto/biography-narrative research as a means of exploratory conduct, based on the narrator’s biography data, also considering the researcher’s autobiographical thought. In the final part of the article I focus on showing the narrative structure of identity and autobiography. I emphasise this relation in definitions qualifying autobiography as written life narration and identity as a narration of autobiography.

Program description of FIBRAM (Fiber Optic Radiation Attenuation Model): a radiation attenuation model for optical fibers

International Nuclear Information System (INIS)

Ingram, W.J.

1987-06-01

The report describes a fiber-optics system model and its computer implementation. This implementation can calculate the bit error ratio (BER) versus time for optical fibers that have been exposed to gamma radiation. The program is designed so that the user may arbitrarily change any or all of the system input variables and produce separate outputs. The primary output of the program is a table of the BER as a function of time. This table may be stored on magnetic media and later incorporated into computer graphic programs. The program was written in FORTRAN 77 for the IBM PC/AT/XT computers. Flow charts and program listings are included in the report

Improving energy efficiency and smart grid program analysis with agent-based end-use forecasting models

International Nuclear Information System (INIS)

Jackson, Jerry

2010-01-01

Electric utilities and regulators face difficult challenges evaluating new energy efficiency and smart grid programs prompted, in large part, by recent state and federal mandates and financial incentives. It is increasingly difficult to separate electricity use impacts of individual utility programs from the impacts of increasingly stringent appliance and building efficiency standards, increasing electricity prices, appliance manufacturer efficiency improvements, energy program interactions and other factors. This study reviews traditional approaches used to evaluate electric utility energy efficiency and smart-grid programs and presents an agent-based end-use modeling approach that resolves many of the shortcomings of traditional approaches. Data for a representative sample of utility customers in a Midwestern US utility are used to evaluate energy efficiency and smart grid program targets over a fifteen-year horizon. Model analysis indicates that a combination of the two least stringent efficiency and smart grid program scenarios provides peak hour reductions one-third greater than the most stringent smart grid program suggesting that reductions in peak demand requirements are more feasible when both efficiency and smart grid programs are considered together. Suggestions on transitioning from traditional end-use models to agent-based end-use models are provided.

In this study, we present an effective model All-Trans Retinoic Acid (ATRA)-induced differentiation of HL-60 cells. The model describes reinforcing feedback between an ATRA-inducible signalsome complex involving many proteins including Vav1, a guanine nucleotide exchange factor, and the activation of the mitogen activated protein kinase (MAPK) cascade. We decomposed the effective model into three modules; a signal initiation module that sensed and transformed an ATRA signal into program activation signals; a signal integration module that controlled the expression of upstream transcription factors; and a phenotype module which encoded the expression of functional differentiation markers from the ATRA-inducible transcription factors. We identified an ensemble of effective model parameters using measurements taken from ATRA-induced HL-60 cells. Using these parameters, model analysis predicted that MAPK activation was bistable as a function of ATRA exposure. Conformational experiments supported ATRA-induced bistability. Additionally, the model captured intermediate and phenotypic gene expression data. Knockout analysis suggested Gfi-1 and PPARg were critical to the ATRAinduced differentiation program. These findings, combined with other literature evidence, suggested that reinforcing feedback is central to hyperactive signaling in a diversity of cell fate programs.

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

Directory of Open Access Journals (Sweden)

2014-06-01

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.

Tang, H.T.; Graves, H.L.; Chen, P.C.

1991-01-01

The Large-Scale Seismic Test (LSST) Program at Hualien, Taiwan, is a follow-on to the soil-structure interaction (SSI) experiments at Lotung, Taiwan. The planned SSI studies will be performed at a stiff soil site in Hualien, Taiwan, that historically has had slightly more destructive earthquakes in the past than Lotung. The LSST is a joint effort among many interested parties. Electric Power Research Institute (EPRI) and Taipower are the organizers of the program and have the lead in planning and managing the program. Other organizations participating in the LSST program are US Nuclear Regulatory Commission (NRC), the Central Research Institute of Electric Power Industry (CRIEPI), the Tokyo Electric Power Company (TEPCO), the Commissariat A L'Energie Atomique (CEA), Electricite de France (EdF) and Framatome. The LSST was initiated in January 1990, and is envisioned to be five years in duration. Based on the assumption of stiff soil and confirmed by soil boring and geophysical results the test model was designed to provide data needed for SSI studies covering: free-field input, nonlinear soil response, non-rigid body SSI, torsional response, kinematic interaction, spatial incoherency and other effects. Taipower had the lead in design of the test model and received significant input from other LSST members. Questions raised by LSST members were on embedment effects, model stiffness, base shear, and openings for equipment. This paper describes progress in site preparation, design and construction of the model and development of an instrumentation plan

Wells, one of Lodge’s favourites, or remain a conventional life story immune to the tenets of contemporary life writing? Is it the work of a (self- historian, or a novelist? Does it belong to the “regime of truth,” or is it the product of memory? Finally, is it, indeed, a memoir (as its subtitle claims, or a specimen of self-biography? The paper will show special interest in the work’s generic characteristics and will offer an attempt to locate Quite a Good Time to Be Born on the map of contemporary life writing practices.

Development of a program logic model and evaluation plan for a participatory ergonomics intervention in construction.

2014-03-01

Intervention studies in participatory ergonomics (PE) are often difficult to interpret due to limited descriptions of program planning and evaluation. 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. 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. 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. © 2013 Wiley Periodicals, Inc.

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

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.

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. PMID:24954939

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

2017-12-01

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

High Performance Programming Using Explicit Shared Memory Model on Cray T3D1

Simon, Horst D.; Saini, Subhash; Grassi, Charles

1994-01-01

The Cray T3D system is the first-phase system in Cray Research, Inc.'s (CRI) three-phase massively parallel processing (MPP) program. This system features a heterogeneous architecture that closely couples DEC's Alpha microprocessors and CRI's parallel-vector technology, i.e., the Cray Y-MP and Cray C90. An overview of the Cray T3D hardware and available programming models is presented. Under Cray Research adaptive Fortran (CRAFT) model four programming methods (data parallel, work sharing, message-passing using PVM, and explicit shared memory model) are available to the users. However, at this time data parallel and work sharing programming models are not available to the user community. The differences between standard PVM and CRI's PVM are highlighted with performance measurements such as latencies and communication bandwidths. We have found that the performance of neither standard PVM nor CRI s PVM exploits the hardware capabilities of the T3D. The reasons for the bad performance of PVM as a native message-passing library are presented. This is illustrated by the performance of NAS Parallel Benchmarks (NPB) programmed in explicit shared memory model on Cray T3D. In general, the performance of standard PVM is about 4 to 5 times less than obtained by using explicit shared memory model. This degradation in performance is also seen on CM-5 where the performance of applications using native message-passing library CMMD on CM-5 is also about 4 to 5 times less than using data parallel methods. The issues involved (such as barriers, synchronization, invalidating data cache, aligning data cache etc.) while programming in explicit shared memory model are discussed. Comparative performance of NPB using explicit shared memory programming model on the Cray T3D and other highly parallel systems such as the TMC CM-5, Intel Paragon, Cray C90, IBM-SP1, etc. is presented.

This is Volume 3 of three volumes of documentation of the International Nuclear Model (INM). This volume presents the Program Description of the International Nuclear Model, which was developed for the Nuclear and Alternate Fuels Division (NAFD), Office of Coal, Nuclear, Electric and Alternate Fuels, Energy Information Administration (EIA), US Department of Energy (DOE). The International Nuclear Model (INM) is a comprehensive model of the commercial nuclear power industry. It simulates economic decisions for reactor deployment and fuel management decision based on an input set of technical economic and scenario parameters. The technical parameters include reactor operating characteristics, fuel cycle timing and mass loss factors, and enrichment tails assays. Economic parameters include fuel cycle costs, financial data, and tax alternatives. INM has a broad range of scenario options covering, for example, process constraints, interregional activities, reprocessing, and fuel management selection. INM reports reactor deployment schedules, electricity generation, and fuel cycle requirements and costs. It also has specialized reports for extended burnup and permanent disposal. Companion volumes to Volume 3 are: Volume 1 - Model Overview, and Volume 2 - Data Base Relationships

frameworks, we have in recent years pursued an agenda of translating hard-real-time embedded safety critical programs written in the Safety Critical Java Profile [33] into networks of timed automata [4] and subjecting those to automated analysis using the UPPAAL model checker [10]. Several tools have been...... built and the tools have been used to analyse a number of systems for properties such as worst case execution time, schedulability and energy optimization [12–14,19,34,36,38]. In this paper we will elaborate on the theoretical underpinning of the translation from Java programs to timed automata models...... and briefly summarize some of the results based on this translation. Furthermore, we discuss future work, especially relations to the work in [16,24] as Java recently has adopted first class higher order functions in the form of lambda abstractions....

Arjmandzadeh, Ziba; Safi, Mohammadreza; Nazemi, Alireza

2017-05-01

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.

Hybrid programming model for implicit PDE simulations on multicore architectures

KAUST Repository

Kaushik, Dinesh; Keyes, David E.; Balay, Satish; Smith, Barry F.

2011-01-01

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.

NASA's Lunar and Planetary Mapping and Modeling Program produces a suite of online visualization and analysis tools. Originally designed for mission planning and science, these portals offer great benefits for education and public outreach (EPO), providing access to data from a wide range of instruments aboard a variety of past and current missions. As a component of NASA's Science EPO Infrastructure, they are available as resources for NASA STEM EPO programs, and to the greater EPO community. As new missions are planned to a variety of planetary bodies, these tools are facilitating the public's understanding of the missions and engaging the public in the process of identifying and selecting where these missions will land. There are currently three web portals in the program: the Lunar Mapping and Modeling Portal or LMMP (http://lmmp.nasa.gov), Vesta Trek (http://vestatrek.jpl.nasa.gov), and Mars Trek (http://marstrek.jpl.nasa.gov). Portals for additional planetary bodies are planned. As web-based toolsets, the portals do not require users to purchase or install any software beyond current web browsers. The portals provide analysis tools for measurement and study of planetary terrain. They allow data to be layered and adjusted to optimize visualization. Visualizations are easily stored and shared. The portals provide 3D visualization and give users the ability to mark terrain for generation of STL files that can be directed to 3D printers. Such 3D prints are valuable tools in museums, public exhibits, and classrooms - especially for the visually impaired. Along with the web portals, the program supports additional clients, web services, and APIs that facilitate dissemination of planetary data to a range of external applications and venues. NASA challenges and hackathons are also providing members of the software development community opportunities to participate in tool development and leverage data from the portals.

Directory of Open Access Journals (Sweden)

Safiyullah Ferozkhan

2016-01-01

Full Text Available Gas compressor performance is vital in oil and gas industry because of the equipment criticality which requires continuous operations. Plant operators often face difficulties in predicting appropriate time for maintenance and would usually rely on time based predictive maintenance intervals as recommended by original equipment manufacturer (OEM. The objective of this work is to develop the computational model to find the isentropic head value using genetic programming. The isentropic head value is calculated from the OEM performance chart. Inlet mass flow rate and speed of the compressor are taken as the input value. The obtained results from the GP computational models show good agreement with experimental and target data with the average prediction error of 1.318%. The genetic programming computational model will assist machinery engineers to quantify performance deterioration of gas compressor and the results from this study will be then utilized to estimate future maintenance requirements based on the historical data. In general, this genetic programming modelling provides a powerful solution for gas compressor operators to realize predictive maintenance approach in their operations.

1993-09-01

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.

Optimal timing of joint replacement using mathematical programming and stochastic programming models.

Science.gov (United States)

Keren, Baruch; Pliskin, Joseph S

2011-12-01

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.

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.

Full Text Available Background: In order to help rheumatoid arthritis (RA patients in carrying out and attaining relevant self-care behaviors and adaptation to the physical limitations of this disease and, conse-quently, promoting their level of health status, an education program based on the PRECEDE component of the PRECEDE–PROCEED model targeting patients with RA was developed. This paper describes the planning of a RA Patient Education Program (RAPEP designed to promote their quality of life.Methods: The development of the program began with a comprehensive review of the literature. This included a review of the signs and symptoms of RA, accompanying functional disabilities, previous educational programs and the effect of the disease on the patient’s quality of life. Be-sides, in order to help inform RAPEP program development, and organize the survey according to the factors identified in the PRECEDE model a cross-sectional survey was applied on a non-prob-ability sample of 181 outpatients in Yazd, center of Iran.Results: The quality of life (QOL problem identified was the considerable low role functioning, health perception and physical functioning due to chronic pain. One of the most significant modi-fiable behavioral factors impacting pain and functional limitations was self-care behaviors in RA patients. Higher level of knowledge, attitude, self-efficacy, enabling factors and social support is associated with better self-care behavior.Conclusions: The PRECEDE component of the PRECEDE–PROCEED model provided a com-prehensive conceptual framework for the development of RAPEP aiming at RA patients in Yazd. Further research to evaluate this educational program is suggested.

The Assessment of Effectiveness of Geologic Isolation Systems (AEGIS) Program is developing and applying the methodology for assessing the far-field, long-term post-closure safety of deep geologic nuclear waste repositories. AEGIS is being performed by Pacific Northwest Laboratory (PNL) under contract with the Office of Nuclear Waste Isolation (OWNI) for the Department of Energy (DOE). One task within AEGIS is the development of methodology for analysis of the consequences (water pathway) from loss of repository containment as defined by various release scenarios. Analysis of the long-term, far-field consequences of release scenarios requires the application of numerical codes which simulate the hydrologic systems, model the transport of released radionuclides through the hydrologic systems to the biosphere, and, where applicable, assess the radiological dose to humans. Hydrologic and transport models are available at several levels of complexity or sophistication. Model selection and use are determined by the quantity and quality of input data. Model development under AEGIS and related programs provides three levels of hydrologic models, two levels of transport models, and one level of dose models (with several separate models). This is the third of 3 volumes of the description of the VTT (Variable Thickness Transient) Groundwater Hydrologic Model - second level (intermediate complexity) two-dimensional saturated groundwater flow

Sustainable Cost Models for mHealth at Scale: Modeling Program Data from m4RH Tanzania.

Full Text Available 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

Kaplan, Deanna M; deBlois, Madeleine; Dominguez, Violeta; Walsh, Michele E

Recent research suggests that school-based kindness education programs may benefit the learning and social-emotional development of youth and may improve school climate and school safety outcomes. However, how and to what extent kindness education programming influences positive outcomes in schools is poorly understood, and such programs are difficult to evaluate in the absence of a conceptual model for studying their effectiveness. In partnership with Kind Campus, a widely adopted school-based kindness education program that uses a bottom-up program framework, a methodology called concept mapping was used to develop a conceptual model for evaluating school-based kindness education programs from the input of 123 middle school students and approximately 150 educators, school professionals, and academic scholars. From the basis of this model, recommendations for processes and outcomes that would be useful to assess in evaluations of kindness education programs are made, and areas where additional instrument development may be necessary are highlighted. The utility of the concept mapping method as an initial step in evaluating other grassroots or non-traditional educational programming is also discussed. Copyright © 2016 Elsevier Ltd.

Full Text Available There is an ever-growing demand for sustainable development (SD plans, in order to foster a country’s economic growth by implementing suitable policies and initiative programs for the development of the primary, the secondary and the tertiary sectors. We present a multi-criteria modeling approach using the linear programming problem (LPP framework for a simultaneous optimization of these three sectors. Furthermore, we develop a fuzzy goal programming (FGP model that provides an optimal allocation of resources by achieving future goals on the gross domestic product (GDP, the electricity consumption (EC and the greenhouse gas (GHG emissions. Furthermore, a weighted model of FGP is presented to obtain varying solutions according to the priorities set by the decision-maker for achieving future goals of GDP growth, EC and GHG emissions. The presented models provide useful insight for decision-makers when implementing strategies across different sectors. As a model country, we chose India by the year 2030. A study of economic policies and sustainable development goals (SDGs for India is finally carried out.

A Hybrid Programming Framework for Modeling and Solving Constraint Satisfaction and Optimization Problems

Directory of Open Access Journals (Sweden)

Paweł Sitek

2016-01-01

Full Text Available This paper proposes a hybrid programming framework for modeling and solving of constraint satisfaction problems (CSPs and constraint optimization problems (COPs. Two paradigms, CLP (constraint logic programming and MP (mathematical programming, are integrated in the framework. The integration is supplemented with the original method of problem transformation, used in the framework as a presolving method. The transformation substantially reduces the feasible solution space. The framework automatically generates CSP and COP models based on current values of data instances, questions asked by a user, and set of predicates and facts of the problem being modeled, which altogether constitute a knowledge database for the given problem. This dynamic generation of dedicated models, based on the knowledge base, together with the parameters changing externally, for example, the user’s questions, is the implementation of the autonomous search concept. The models are solved using the internal or external solvers integrated with the framework. The architecture of the framework as well as its implementation outline is also included in the paper. The effectiveness of the framework regarding the modeling and solution search is assessed through the illustrative examples relating to scheduling problems with additional constrained resources.

Lee, Youn Myoung; Hwang, Yong Soo; Kang, Chul Hyung; Lee, Sung Ho

2009-12-01

Modeling study and development of a total system performance assessment (TSPA) program, by which an assessment of safety and performance for a low- and intermediate-level radioactive waste disposal repository with normal or abnormal nuclide release cases associated with the various FEPs involved in the performance of the proposed repository could be made has been carrying out by utilizing GoldSim under contract with KRMC. The report deals with a detailed conceptual modeling scheme by which a GoldSim program modules, all of which are integrated into a TSPA program as well as the input data set currently available. In-depth system models that are conceptually and rather practically described and then ready for implementing into a GoldSim program are introduced with plenty of illustrative conceptual models and sketches. The GoldSim program that will be finally developed through this project is expected to be successfully applied to the post closure safety assessment required both for the LILW repository and pyro processed repository by the regulatory body with both increased practicality and much reduced uncertainty

Using Runtime Analysis to Guide Model Checking of Java Programs

Science.gov (United States)

Havelund, Klaus; Norvig, Peter (Technical Monitor)

2001-01-01

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.

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

Energy Technology Data Exchange (ETDEWEB)

Kaellblad, K

1998-05-01

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

Carbajo, J.J.

1984-01-01

Extensive testing has been conducted in the Simulant Boiling Flow Visualization (SBFV) loop in which water is boiled in a vertical transparent tube by circulating hot glycerine in an annulus surrounding the tube. Tests ranged from nonboiling forced convection to oscillatory boiling natural convection. The program LOOP-W has been developed to analyze these tests. This program is a multi-leg, one-dimensional, two-phase equilibrium model with slip between the phases. In this study, a specific test, performed at low power where non-boiling forced convection was changed to boiling natural convection and then to non-boiling again, has been modeled with the program LOOP-W

Nagy, Christopher J; Fitzgerald, Brian M; Kraus, Gregory P

2014-01-01

Anesthesiology residency programs will be expected to have Milestones-based evaluation systems in place by July 2014 as part of the Next Accreditation System. The San Antonio Uniformed Services Health Education Consortium (SAUSHEC) anesthesiology residency program developed and implemented a Milestones-based feedback and evaluation system a year ahead of schedule. It has been named the Milestone-specific, Observed Data points for Evaluating Levels of performance (MODEL) assessment strategy. The "MODEL Menu" and the "MODEL Blueprint" are tools that other anesthesiology residency programs can use in developing their own Milestones-based feedback and evaluation systems prior to ACGME-required implementation. Data from our early experience with the streamlined MODEL blueprint assessment strategy showed substantially improved faculty compliance with reporting requirements. The MODEL assessment strategy provides programs with a workable assessment method for residents, and important Milestones data points to programs for ACGME reporting.

[Migration biography and culture as determinants of diagnostic and therapeutic processes in mentally ill immigrants. A systematic differentiation based on a qualitative content analysis of treatment courses].

Science.gov (United States)

Behrens, Katharina; Calliess, Iris Tatjana

2008-01-01

A systematic differentiation of culture- in contrast to migration-related influence factors in diagnostic and therapeutic processes is introduced. "Culture-related" refers to characteristics caused by values, behavior norms and religious attitudes of the ethnic community a person belongs to. "Migration-specific" refers to consequences of moving one's residence from one country to another (e. g., absence of family, trouble with authorities concerning the legal status or ambivalence with respect to returning to the home country). Based on a theoretic background of these determinants, categories for a content analysis were defined and applied to the treatment records of n = 55 first generation immigrants treated in a psychiatric day clinic of an university hospital. The results suggest that migration biography should not only be considered as affecting vulnerability in the genesis of a mental illness, but rather be classified as a factor of at least as much relevance for therapeutic situations as the usually named cultural diversity: summarizing the results of the qualitative content analysis of the entire treatment courses more cases were influenced by migration specific aspects rather than culture specific aspects.

Social change and women's health.

McDonough, Peggy; Worts, Diana; McMunn, Anne; Sacker, Amanda

2013-01-01

Over the past five decades, the organization of women's lives has changed dramatically. Throughout the industrialized world, paid work and family biographies have been altered as the once-dominant role of homemaker has given way to the role of secondary, dual, or even primary wage-earner. The attendant changes represent a mix of gains and losses for women, in which not all women have benefited (or suffered) equally. But little is known about the health consequences. This article addresses that gap. It develops a "situated biographies" model to conceptualize how life course change may influence women's health. The model stresses the role of time, both as individual aging and as the anchoring of lives in particular historical periods. "Situating" biographies in this way highlights two key features of social change in women's lives: the ambiguous implications for the health of women as a group, and the probable connections to growing social and economic disparities in health among them. This approach lays the groundwork for more integrated and productive population-based research about how historical transformations may affect women's health.

The NASA/National Space Science Data Center trapped radiation environment model program, 1964 - 1991

International Nuclear Information System (INIS)

Vette, J.I.

1991-11-01

The major effort that NASA, initially with the help of the United States Air Force (USAF), carried out for 27 years to synthesize the experimental and theoretical results of space research related to energetic charged particles into a quantitative description of the terrestrial trapped radiation environment in the form of model environments is detailed. The effort is called the Trapped Radiation Environment Modeling Program (TREMP). In chapter 2 the historical background leading to the establishment of this program is given. Also, the purpose of this modeling program as established by the founders of the program is discussed. This is followed in chapter 3 by the philosophy and approach that was applied in this program throughout its lifetime. As will be seen, this philosophy led to the continuation of the program long after it would have expired. The highlights of the accomplishments are presented in chapter 4. A view to future possible efforts in this arena is given in chapter 5, mainly to pass on to future workers the differences that are perceived from these many years of experience. Chapter 6 is an appendix that details the chronology of the development of TREMP. Finally, the references, which document the work accomplished over these years, are presented in chapter 7

1978-03-01

A generalized fish life-cycle population model and computer program have been prepared to evaluate the long-term effect of changes in mortality in age class 0. The general question concerns what happens to a fishery when density-independent sources of mortality are introduced that act on age class 0, particularly entrainment and impingement at power plants. This paper discusses the model formulation and computer program, including sample results. The population model consists of a system of difference equations involving age-dependent fecundity and survival. The fecundity for each age class is assumed to be a function of both the fraction of females sexually mature and the weight of females as they enter each age class. Natural mortality for age classes 1 and older is assumed to be independent of population size. Fishing mortality is assumed to vary with the number and weight of fish available to the fishery. Age class 0 is divided into six life stages. The probability of survival for age class 0 is estimated considering both density-independent mortality (natural and power plant) and density-dependent mortality for each life stage. Two types of density-dependent mortality are included. These are cannibalism of each life stage by older age classes and intra-life-stage competition

Zhao, Erdong; Li, Shangqi

2017-08-01

As the main body of power grid operation, county-level power supply enterprises undertake an important emission to guarantee the security of power grid operation and safeguard social power using order. The optimization of grid construction projects has been a key issue of power supply capacity and service level of grid enterprises. According to the actual situation of power grid construction project optimization of county-level power enterprises, on the basis of qualitative analysis of the projects, this paper builds a Bi-level programming model based on quantitative analysis. The upper layer of the model is the target restriction of the optimal portfolio; the lower layer of the model is enterprises’ financial restrictions on the size of the enterprise project portfolio. Finally, using a real example to illustrate operation proceeding and the optimization result of the model. Through qualitative analysis and quantitative analysis, the bi-level programming model improves the accuracy and normative standardization of power grid enterprises projects.

Wavelet-linear genetic programming: A new approach for modeling monthly streamflow

Science.gov (United States)

Ravansalar, Masoud; Rajaee, Taher; Kisi, Ozgur

2017-06-01

The streamflows are important and effective factors in stream ecosystems and its accurate prediction is an essential and important issue in water resources and environmental engineering systems. A hybrid wavelet-linear genetic programming (WLGP) model, which includes a discrete wavelet transform (DWT) and a linear genetic programming (LGP) to predict the monthly streamflow (Q) in two gauging stations, Pataveh and Shahmokhtar, on the Beshar River at the Yasuj, Iran were used in this study. In the proposed WLGP model, the wavelet analysis was linked to the LGP model where the original time series of streamflow were decomposed into the sub-time series comprising wavelet coefficients. The results were compared with the single LGP, artificial neural network (ANN), a hybrid wavelet-ANN (WANN) and Multi Linear Regression (MLR) models. The comparisons were done by some of the commonly utilized relevant physical statistics. The Nash coefficients (E) were found as 0.877 and 0.817 for the WLGP model, for the Pataveh and Shahmokhtar stations, respectively. The comparison of the results showed that the WLGP model could significantly increase the streamflow prediction accuracy in both stations. Since, the results demonstrate a closer approximation of the peak streamflow values by the WLGP model, this model could be utilized for the simulation of cumulative streamflow data prediction in one month ahead.

Coping modeling problem solving versus mastery modeling: effects on adherence, in-session process, and skill acquisition in a residential parent-training program.

Science.gov (United States)

Cunningham, C E; Davis, J R; Bremner, R; Dunn, K W; Rzasa, T

1993-10-01

This trial compared two approaches used to introduce parenting skills in a residential staff training program. Fifty staff were randomly assigned to: mastery modelling in which videotaped models demonstrated new skills, coping modelling problem solving (CMPS) in which participants formulated their own solutions to the errors depicted by videotaped models, or a waiting-list control group. In both, leaders used modelling, role playing, and homework projects to promote mastery and transfer of new skills. The skills of all groups improved, but CMPS participants attended more sessions, were late to fewer sessions, completed more homework, engaged in more cooperative in-session interaction, rated the program more positively, and reported higher job accomplishment scores. These data suggest that CMPS allowing participants to formulate their own solutions may enhance adherence and reduce the resistance observed in more didactic programs.

2008-01-01

NASA's Constellation Program is embarking on a new era of space exploration, returning to the Moon and beyond. The Constellation architecture will consist of a number of new spacecraft elements, including the Orion crew exploration vehicle, the Altair lunar lander, and the Ares family of launch vehicles. Each of these new spacecraft elements will need an electric power system, and those power systems will need to be designed to fulfill unique mission objectives and to survive the unique environments encountered on a lunar exploration mission. As with any new spacecraft power system development, preliminary design work will rely heavily on analysis to select the proper power technologies, size the power system components, and predict the system performance throughout the required mission profile. Constellation projects have the advantage of leveraging power system modeling developments from other recent programs such as the International Space Station (ISS) and the Mars Exploration Program. These programs have developed mature power system modeling tools, which can be quickly modified to meet the unique needs of Constellation, and thus provide a rapid capability for detailed power system modeling that otherwise would not exist.

A Pareto-optimal moving average multigene genetic programming model for daily streamflow prediction

Science.gov (United States)

Danandeh Mehr, Ali; Kahya, Ercan

2017-06-01

Genetic programming (GP) is able to systematically explore alternative model structures of different accuracy and complexity from observed input and output data. The effectiveness of GP in hydrological system identification has been recognized in recent studies. However, selecting a parsimonious (accurate and simple) model from such alternatives still remains a question. This paper proposes a Pareto-optimal moving average multigene genetic programming (MA-MGGP) approach to develop a parsimonious model for single-station streamflow prediction. The three main components of the approach that take us from observed data to a validated model are: (1) data pre-processing, (2) system identification and (3) system simplification. The data pre-processing ingredient uses a simple moving average filter to diminish the lagged prediction effect of stand-alone data-driven models. The multigene ingredient of the model tends to identify the underlying nonlinear system with expressions simpler than classical monolithic GP and, eventually simplification component exploits Pareto front plot to select a parsimonious model through an interactive complexity-efficiency trade-off. The approach was tested using the daily streamflow records from a station on Senoz Stream, Turkey. Comparing to the efficiency results of stand-alone GP, MGGP, and conventional multi linear regression prediction models as benchmarks, the proposed Pareto-optimal MA-MGGP model put forward a parsimonious solution, which has a noteworthy importance of being applied in practice. In addition, the approach allows the user to enter human insight into the problem to examine evolved models and pick the best performing programs out for further analysis.

Systemic Analysis, Mapping, Modeling, and Simulation of the Advanced Accelerator Applications Program

Guan, Yue; Laidler, James J.; Morman, James A.

2002-01-01

Advanced chemical separations methods envisioned for use in the Department of Energy Advanced Accelerator Applications (AAA) program have been studied using the Systemic Analysis, Mapping, Modeling, and Simulation (SAMMS) method. This integrated and systematic method considers all aspects of the studied process as one dynamic and inter-dependent system. This particular study focuses on two subjects: the chemical separation processes for treating spent nuclear fuel, and the associated non-proliferation implications of such processing. Two levels of chemical separation models are developed: level 1 models treat the chemical process stages by groups; and level 2 models depict the details of each process stage. Models to estimate the proliferation risks based on proliferation barrier assessment are also developed. This paper describes the research conducted for the single-stratum design in the AAA program. Further research conducted for the multi-strata designs will be presented later. The method and models described in this paper can help in the design of optimized processes that fulfill the chemical separation process specifications and non-proliferation requirements. (authors)

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.

An Environmental Management Maturity Model of Construction Programs Using the AHP-Entropy Approach

Directory of Open Access Journals (Sweden)

Libiao Bai

2018-06-01

Full Text Available The accelerating process of urbanization in China has led to considerable opportunities for the development of construction projects, however, environmental issues have become an important constraint on the implementation of these projects. To quantitatively describe the environmental management capabilities of such projects, this paper proposes a 2-dimensional Environmental Management Maturity Model of Construction Program (EMMMCP based on an analysis of existing projects, group management theory and a management maturity model. In this model, a synergetic process was included to compensate for the lack of consideration of synergies in previous studies, and it was involved in the construction of the first dimension, i.e., the environmental management index system. The second dimension, i.e., the maturity level of environment management, was then constructed by redefining the hierarchical characteristics of construction program (CP environmental management maturity. Additionally, a mathematical solution to this proposed model was derived via the Analytic Hierarchy Process (AHP-entropy approach. To verify the effectiveness and feasibility of this proposed model, a computational experiment was conducted, and the results show that this approach could not only measure the individual levels of different processes, but also achieve the most important objective of providing a reference for stakeholders when making decisions on the environmental management of construction program, which reflects this model is reasonable for evaluating the level of environmental management maturity in CP. To our knowledge, this paper is the first study to evaluate the environmental management maturity levels of CP, which would fill the gap between project program management and environmental management and provide a reference for relevant management personnel to enhance their environmental management capabilities.

Nutritional programming of gastrointestinal tract development. Is the pig a good model for man?

Guilloteau, Paul; Zabielski, Romuald; Hammon, Harald M; Metges, Cornelia C

2010-06-01

The consequences of early-life nutritional programming in man and other mammalian species have been studied chiefly at the metabolic level. Very few studies, if any, have been performed in the gastrointestinal tract (GIT) as the target organ, but extensive GIT studies are needed since the GIT plays a key role in nutrient supply and has an impact on functions of the entire organism. The possible deleterious effects of nutritional programming at the metabolic level were discovered following epidemiological studies in human subjects, and confirmed in animal models. Investigating the impact of programming on GIT structure and function would need appropriate animal models due to ethical restrictions in the use of human subjects. The aim of the present review is to discuss the use of pigs as an animal model as a compromise between ethically acceptable animal studies and the requirement of data which can be interpolated to the human situation. In nutritional programming studies, rodents are the most frequently used model for man, but GIT development and digestive function in rodents are considerably different from those in man. In that aspect, the pig GIT is much closer to the human than that of rodents. The swine species is closely comparable with man in many nutritional and digestive aspects, and thus provides ample opportunity to be used in investigations on the consequences of nutritional programming for the GIT. In particular, the 'sow-piglets' dyad could be a useful tool to simulate the 'human mother-infant' dyad in studies which examine short-, middle- and long-term effects and is suggested as the reference model.

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

International Nuclear Information System (INIS)

Hallstadius, L.

1986-01-01

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)

Hai-Feng Huo

2014-01-01

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.

Bringing Automated Model Checking to PLC Program Development - A CERN Case Study

CERN Document Server

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

2014-01-01

Verification of critical software is a high priority but a challenging task for industrial control systems. Model checking appears to be an appropriate approach for this purpose. However, this technique is not widely used in industry yet, due to some obstacles. The main obstacles encountered when trying to apply formal verification techniques at industrial installations are the difficulty of creating models out of PLC programs and defining formally the specification requirements. In addition, models produced out of real-life programs have a huge state space, thus preventing the verification due to performance issues. Our work at CERN (European Organization for Nuclear Research) focuses on developing efficient automatic verification methods for industrial critical installations based on PLC (Programmable Logic Controller) control systems. In this paper, we present a tool generating automatically formal models out of PLC code. The tool implements a general methodology which can support several input languages, ...

1992-01-01

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.

NEURO-FUZZY MODELING APPLIED IN PROGRAM MANAGEMENT TO INCREASE LOCAL PUBLIC ADMINISTRATION PERFORMANCE

Directory of Open Access Journals (Sweden)

Adrian-Mihai Zaharia-Radulescu

2016-07-01

Full Text Available One of the challenges in local public administration is dealing with an increasing number of competing requests coming from the communities they serve. The traditional approach would be to handle each request as a standalone project and be prioritized according to benefits and budget available. More and more nowadays program management is becoming a standard approach in managing the initiatives of local public administration. Program management approach is itself an enabler for performance in public sector organizations by allowing an organization to better coordinate its efforts and resources in managing a portfolio of projects. This paper aims to present how neuro-fuzzy modeling applied in program management can help an organization to increase its performance. Neuro-fuzzy modeling would lead organizations one step further by allowing them to simulate different scenarios and manage better the risks accompanying their initiatives. The research done by the authors is theoretical and combines knowledge from different areas and a neuro-fuzzy model is proposed and discussed.

EnergyPlus{trademark} is a new generation computer software analysis tool that has been developed, tested, and commercialized to support DOE's Building Technologies (BT) Program in terms of whole-building, component, and systems R&D (http://www.energyplus.gov). It is also being used to support evaluation and decision making of zero energy building (ZEB) energy efficiency and supply technologies during new building design and existing building retrofits. Version 1.0 of EnergyPlus was released in April 2001, followed by semiannual updated versions over the ensuing seven-year period. This report summarizes work performed by the University of Central Florida's Florida Solar Energy Center (UCF/FSEC) to expand the modeling capabilities of EnergyPlus. The project tasks involved implementing, testing, and documenting the following new features or enhancement of existing features: (1) A model for packaged terminal heat pumps; (2) A model for gas engine-driven heat pumps with waste heat recovery; (3) Proper modeling of window screens; (4) Integrating and streamlining EnergyPlus air flow modeling capabilities; (5) Comfort-based controls for cooling and heating systems; and (6) An improved model for microturbine power generation with heat recovery. UCF/FSEC located existing mathematical models or generated new model for these features and incorporated them into EnergyPlus. The existing or new models were (re)written using Fortran 90/95 programming language and were integrated within EnergyPlus in accordance with the EnergyPlus Programming Standard and Module Developer's Guide. Each model/feature was thoroughly tested and identified errors were repaired. Upon completion of each model implementation, the existing EnergyPlus documentation (e.g., Input Output Reference and Engineering Document) was updated with information describing the new or enhanced feature. Reference data sets were generated for several of the features to aid program users in selecting proper

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

Directory of Open Access Journals (Sweden)

Hideki Katagiri

2017-10-01

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.

Full Text Available Production planning is one of the most important functions in the process of production management. Production planning in the intermediate range of time is termed as aggregate production planning (APP. Aggregate production planning is an important upper level planning activity in a production management system. The present study tries to suggest an aggregate production planning model for products of Hafez tile factory during one year. Due to this fact that the director of the company seeks 3 main objectives to determine the optimal production rate, the linear goal planning method was employed. After solving the problem, in order to examine the efficiency and the distinctiveness of this method in compare to linear programming, the problem was modeled just by considering one objective then was solved by linear programming approach. The findings revealed the goal programming with multi objectives resulted more appropriate solution rather than linear programming with just one objective.

Full Text Available Introduction: Precise prediction of river flows is the key factor for proper planning and management of water resources. Thus, obtaining the reliable methods for predicting river flows has great importance in water resource engineering. In the recent years, applications of intelligent methods such as artificial neural networks, fuzzy systems and genetic programming in water science and engineering have been grown extensively. These mentioned methods are able to model nonlinear process of river flows without any need to geometric properties. A huge number of studies have been reported in the field of using intelligent methods in water resource engineering. For example, Noorani and Salehi (23 presented a model for predicting runoff in Lighvan basin using adaptive neuro-fuzzy network and compared the performance of it with neural network and fuzzy inference methods in east Azerbaijan, Iran. Nabizadeh et al. (21 used fuzzy inference system and adaptive neuro-fuzzy inference system in order to predict river flow in Lighvan river. Khalili et al. (13 proposed a BL-ARCH method for prediction of flows in Shaharchay River in Urmia. Khu et al. (16 used genetic programming for runoff prediction in Orgeval catchment in France. Firat and Gungor (11 evaluated the fuzzy-neural model for predicting Mendes river flow in Turkey. The goal of present study is comparing the performance of genetic programming and M5 model trees for prediction of Shaharchay river flow in the basin of Lake Urmia and obtaining a comprehensive insight of their abilities. Materials and Methods: Shaharchay river as a main source of providing drinking water of Urmia city and agricultural needs of surrounding lands and finally one of the main input sources of Lake Urmia is quite important in the region. For obtaining the predetermined goals of present study, average monthly flows of Shaharchay River in Band hydrometric station has been gathered from 1951 to 2011. Then, two third of mentioned

A multi-gene genetic programming technique is proposed as a new method to predict syngas yield production and the lower heating value for municipal solid waste gasification in a fluidized bed gasifier. The study shows that the predicted outputs of the municipal solid waste gasification process are in good agreement with the experimental dataset and also generalise well to validation (untrained) data. Published experimental datasets are used for model training and validation purposes. The results show the effectiveness of the genetic programming technique for solving complex nonlinear regression problems. The multi-gene genetic programming are also compared with a single-gene genetic programming model to show the relative merits and demerits of the technique. This study demonstrates that the genetic programming based data-driven modelling strategy can be a good candidate for developing models for other types of fuels as well.

SUBCALC, a Microsoft reg-sign Windows trademark application, allows users to map magnetic fields in or around electric utility substations from common types of substation equipment. SUBCALC allows users to create a substation using predefined transmission and distribution lines and other substation components and to quickly modify them to match the desired operating conditions. Users have the option of invoking Power Line Calculator, a program that integrates with SUBCALC, to define power line conditions such as currents, phase angles, power factor, or symmetric components for three-phase lines that are unbalanced or carry net current. SUBCALC 2.0 offers numerous modeling, user interface, and editing enhancements. For example, users can now produce multi-segmented linear profile plots, take spot measurements anywhere in the model, extend lines with automatic connectivity to preexisting structures, and produce phantom extensions of lines beyond the model to avoid a ''stunted'' appearance to the field map. The program's output is available in four possible formats, including a three-dimensional map of the magnetic field, two-dimensional contours, two-dimensional profile plots, and a table with statistical values. All formats may be printed, accompanied by a three-dimensional view of the world the user has drawn

Full Text Available An equilibrium chance-constrained multiobjective programming model with birandom parameters is proposed. A type of linear model is converted into its crisp equivalent model. Then a birandom simulation technique is developed to tackle the general birandom objective functions and birandom constraints. By embedding the birandom simulation technique, a modified genetic algorithm is designed to solve the equilibrium chance-constrained multiobjective programming model. We apply the proposed model and algorithm to a real-world inventory problem and show the effectiveness of the model and the solution method.

Patients' mental models and adherence to outpatient physical therapy home exercise programs.

Science.gov (United States)

Rizzo, Jon

2015-05-01

Within physical therapy, patient adherence usually relates to attending appointments, following advice, and/or undertaking prescribed exercise. Similar to findings for general medical adherence, patient adherence to physical therapy home exercise programs (HEP) is estimated between 35 and 72%. Adherence to HEPs is a multifactorial and poorly understood phenomenon, with no consensus regarding a common theoretical framework that best guides empirical or clinical efforts. Mental models, a construct used to explain behavior and decision-making in the social sciences, may serve as this framework. Mental models comprise an individual's tacit thoughts about how the world works. They include assumptions about new experiences and expectations for the future based on implicit comparisons between current and past experiences. Mental models play an important role in decision-making and guiding actions. This professional theoretical article discusses empirical research demonstrating relationships among mental models, prior experience, and adherence decisions in medical and physical therapy contexts. Specific issues related to mental models and physical therapy patient adherence are discussed, including the importance of articulation of patients' mental models, assessment of patients' mental models that relate to exercise program adherence, discrepancy between patient and provider mental models, and revision of patients' mental models in ways that enhance adherence. The article concludes with practical implications for physical therapists and recommendations for further research to better understand the role of mental models in physical therapy patient adherence behavior.

We present integer programming models for some variants of the farthest string problem. The number of variables and constraints is substantially less than that of the integer linear programming models known in the literature. Moreover, the solution of the linear programming-relaxation contains only a small proportion of noninteger values, which considerably simplifies the rounding process. Numerical tests have shown excellent results, especially when a small set of long sequences is given.

Based on the power conversion system of nuclear and conventional islands of Daya Bay Power Station, this paper models the thermal-hydraulic systems of primary and secondary loops for PWR by using the PWR best-estimate program-RELAP5. To simulate the full-scope power conversion system, not only the traditional basic system models of nuclear island, but also the major system models of conventional island are all considered and modeled. A comparison between the calculated results and the actual data of reactor demonstrates a fine match for Daya Bay Nuclear Power Station, and manifests the feasibility in simulating full-scope power conversion system of PWR by RELAP5 at the same time.

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

International Nuclear Information System (INIS)

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

1983-05-01

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

Programming models for energy-aware systems

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

In an indeterminacy economic environment, experts' knowledge about the returns of securities consists of much uncertainty instead of randomness. This paper discusses portfolio selection problem in uncertain environment in which security returns cannot be well reflected by historical data, but can be evaluated by the experts. In the paper, returns of securities are assumed to be given by uncertain variables. According to various decision criteria, the portfolio selection problem in uncertain environment is formulated as expected-variance-chance model and chance-expected-variance model by using the uncertainty programming. Within the framework of uncertainty theory, for the convenience of solving the models, some crisp equivalents are discussed under different conditions. In addition, a hybrid intelligent algorithm is designed in the paper to provide a general method for solving the new models in general cases. At last, two numerical examples are provided to show the performance and applications of the models and algorithm.

An inexact nonlinear mλ-measure fuzzy chance-constrained programming (INMFCCP) model is developed for irrigation water allocation under uncertainty. Techniques of inexact quadratic programming (IQP), mλ-measure, and fuzzy chance-constrained programming (FCCP) are integrated into a general optimization framework. The INMFCCP model can deal with not only nonlinearities in the objective function, but also uncertainties presented as discrete intervals in the objective function, variables and left-hand side constraints and fuzziness in the right-hand side constraints. Moreover, this model improves upon the conventional fuzzy chance-constrained programming by introducing a linear combination of possibility measure and necessity measure with varying preference parameters. To demonstrate its applicability, the model is then applied to a case study in the middle reaches of Heihe River Basin, northwest China. An interval regression analysis method is used to obtain interval crop water production functions in the whole growth period under uncertainty. Therefore, more flexible solutions can be generated for optimal irrigation water allocation. The variation of results can be examined by giving different confidence levels and preference parameters. Besides, it can reflect interrelationships among system benefits, preference parameters, confidence levels and the corresponding risk levels. Comparison between interval crop water production functions and deterministic ones based on the developed INMFCCP model indicates that the former is capable of reflecting more complexities and uncertainties in practical application. These results can provide more reliable scientific basis for supporting irrigation water management in arid areas.

How robotics programs influence young women's career choices : a grounded theory model

Craig, Cecilia Dosh-Bluhm

The fields of engineering, computer science, and physics have a paucity of women despite decades of intervention by universities and organizations. Women's graduation rates in these fields continue to stagnate, posing a critical problem for society. This qualitative grounded theory (GT) study sought to understand how robotics programs influenced young women's career decisions and the program's effect on engineering, physics, and computer science career interests. To test this, a study was mounted to explore how the FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition (FRC) program influenced young women's college major and career choices. Career theories suggested that experiential programs coupled with supportive relationships strongly influence career decisions, especially for science, technology, engineering, and mathematics careers. The study explored how and when young women made career decisions and how the experiential program and! its mentors and role models influenced career choice. Online focus groups and interviews (online and face-to-face) with 10 female FRC alumnae and GT processes (inductive analysis, open coding, categorizations using mind maps and content clouds) were used to generate a general systems theory style model of the career decision process for these young women. The study identified gender stereotypes and other career obstacles for women. The study's conclusions include recommendations to foster connections to real-world challenges, to develop training programs for mentors, and to nurture social cohesion, a mostly untapped area. Implementing these recommendations could help grow a critical mass of women in engineering, physics, and computer science careers, a social change worth pursuing.
