  2. 2D analytical modeling of distortion and sky background in multi-fiber spectrographs the case of the Norris spectrograph at Palomar Mountain

    CERN Document Server

    Viton, M; Viton, Maurice; Milliard, Bruno

    2002-01-01

    A method for optimal reduction of data taken with multi-fiber spectrographs is described, based on global correction of their geometrical distortion. Though it was specifically developed for reducing observations performed at Palomar Mountain using the Norris fiber spectrograph, this method can be adapted to other types of multi-object spectrographs such as the multi-slit ones. Combined with a 2D analytical interpolation of sky-background that accounts for non-uniform spectral resolution, the Norris software package achieves very high accuracy in airglow subtraction, even in the near infrared (7000-9000A) where molecular band-emissions commonly induce strong artefacts that preclude clean sky subtraction whenever standard image processing techniques are used. Correlatively, an improvement by a factor of 2 on the precision of radial velocities is achievable. Throughout the paper possible improvements to the method are suggested for those devising similar packages for other instruments.

    Stored on a reel of microfilm are three faint and barely readable letters written on the occasion of Norris Bradbury’s fifteen-year anniversary as Director of the (then) Los Alamos Science Laboratory. The first letter, written by Los Alamos Public Relations Officer John V. Young, asks Oppenheimer to send a “congratulatory message to be read at a ceremony honoring Bradbury’s tenure as Laboratory Director. The second letter is Oppenheimer’s response to Young, and the third is Oppenheimer’s congratulatory message to Bradbury. The three letters are transcribed below.

  4. Henry Norris Russell and the Expanding Universe

    CERN Document Server

    DeVorkin, David H

    2013-01-01

    Henry Norris Russell, one of the most influential American astronomers of the first half of the 20th Century, had a special place in his heart for the Lowell Observatory. Although privately critical of the founder for his pronouncements about life on Mars and the superiority of the Mars Hill observing site, he always supported the Observatory in public and professional circles. He staunchly supported Tombaugh's detection of a planet as leading from Lowell's prediction, and always promoted V. M. Slipher's spectroscopic investigations of planetary and stellar phenomena. But how did he react to Slipher's puzzling detection of the extreme radial velocities of spiral nebulae starting in 1912, and how did he regard the extension and interpretation of those observations by Hubble and others in following decades? Here we describe the arc of Russell's reactions, dating from Slipher's first detection, as an indicator of how mainstream stellar astronomers reacted to the concept of an expanding universe.

    2007-12-01

    John Norris Bahcall, one of the most creative and influential astrophysicists of his generation — a scientist who helped prove what makes the Sun shine and helped make the Hubble Space Telescope a reality — passed away in Pasadena, California, on 17 August 2005. Bahcall died peacefully in his sleep from a rare blood disorder. For the past 35 years, Bahcall was the Richard Black Professor of Natural Sciences at the Institute for Advanced Study in Princeton, New Jersey, where he created one of the leading astrophysics programs in the world. Active and working to the end, Bahcall said that he was always grateful for a full and happy life that exceeded his wildest expectations. Bahcall died as he lived, surrounded by the family he loved, embracing life to its fullest, happy, working and joking to the end. Bahcall's stellar career encompassed seminal contributions in numerous fields of astrophysics as well as extraordinary leadership on behalf of the scientific community, including the American Astronomical Society, the American Physical Society, the National Academy of Sciences, NASA, and Congress. Bahcall's contributions made him one of the scientific leaders of his time. He had been recognized by numerous awards including the 1998 National Medal of Science from President Clinton, the Gold Medal of the Royal Astronomical Society, the Medal of the Swedish Royal Academy, the Dan David Award, the Fermi Award, the first Hans Bethe Prize, the Franklin Medal, the Comstock Prize in physics, NASA's Exceptional Scientific Achievement Medal, NASA's Distinguished Public Service Medal, and the top awards of the American Astronomical Society — including the Russell Award, the Heineman Prize, and the Warner Prize. Bahcall was elected to the National Academy of Sciences in 1976 and to the American Philosophical Society in 2001. He was the recipient of Honorary Degrees from numerous universities around the world. Bahcall's scientific interests and expertise ranged from neutrino

  7. Joseph Conrad's Lord Jim: Reconsiderations

    Directory of Open Access Journals (Sweden)

    Ali Albashir Mohammed Al-Haj

    2014-12-01

    Full Text Available The present study aims at reconsidering critically Joseph Conrad's Lord Jim. Joseph Conrad is a great master of English prose who writes normally of the sea, of the Eastern islands, of the English character as seen against a background of the exotic or faced with difficulties. The power of Conrad's feelings for Jim, as well as the force of his judgment  against him, are the responses  of a man mightily involved on two planes, one personal and one public , with the dynamics of good and evil. The evil in Lord Jim is one thing on the surface and another beneath our grasp. It is of course the evil of men who have no sense of loyalty to anything.

    Jim Pollack was an extraordinary scientist. Since receiving his Ph.D. from Harvard in 1965, he published hundreds of papers in scientific journals, encyclopedias, popular magazines, and books. The sheer volume of this kind of productivity is impressive enough, but when considering the diversity and detail of his work, these accomplishments seem almost superhuman. Jim studied and wrote about every planet in the solar system. For, this he was perhaps the most distinguished planetary scientist of his generation. He successfully identified the composition of Saturn's rings and Venus's clouds. With his collaborators, he created the first detailed models for the formation of the outer planets, and the general circulation of the Martian atmosphere. His interest in Mars dust storms provided a foundation for the "nuclear winter" theory that ultimately helped shape foreign policy in the cold war era. Jim's creative talents brought him many awards including the Kuiper Award of the Division of Planetary Sciences, the Leo Szilard Award of the American Physical Society, H. Julian Allen award of the Ames Research Center, and several NASA medals for exceptional scientific achievement.

    Multiple environmental tracers are used to investigate age distribution, evolution, and mixing in local- to regional-scale groundwater circulation around the Norris Geyser Basin area in Yellowstone National Park. Springs ranging in temperature from 3??C to 90??C in the Norris Geyser Basin area were sampled for stable isotopes of hydrogen and oxygen, major and minor element chemistry, dissolved chlorofluorocarbons, and tritium. Groundwater near Norris Geyser Basin is comprised of two distinct systems: a shallow, cool water system and a deep, high-temperature hydrothermal system. These two end-member systems mix to create springs with intermediate temperature and composition. Using multiple tracers from a large number of springs, it is possible constrain the distribution of possible flow paths and refine conceptual models of groundwater circulation in and around a large, complex hydrothermal system.

    In 1956 the Enrico Fermi Presidential Award was established to recognize scientists, engineers, and science policymakers who gave unstintingly over their careers to advance energy science and technology. The first recipient was John von Neumann. .1 Among those scientists who were thought eligible for the award were Hans Bethe, J. Robert Oppenheimer, and Edward Teller. In 1959 Norris Bradbury was asked to comment on the relative merits of each these three men, whom he knew well from their affiliation with Los Alamos. Below is a reproduction of the letter Bradbury sent to Dr. Warren C. Johnson of the AEC’s General Advisory Committee(GAC) containing his evaluation of each man. The letter might surprise those not accustomed to Bradbury’s modus operandi of providing very detailed and forthright answers to the AEC. The letter, itself, was found in cache of old microfilm. Whether because of the age of the microfilm or the quality of the filming process, portions of the letter are not legible. Where empty brackets appear, the word or words could not be read or deduced. Words appearing in brackets are guesses that appear, from the image, to be what was written. These guesses, of course, are just that – guesses.

    Frequent estimation of heat flux in active hydrothermal areas are required to monitor the variation in activity. Natural changes in geothermal and hydrothermal features can include rapid significant changes in surface temperature distribution and may be an indication of "re-plumbing" of the systems or potential hydrothermal explosions. Frequent monitoring of these systems can help Park managers make informed decisions on infrastructure development and/or take precautionary actions to protect the public. Norris Geyser Basin (NGB) is one of Yellowstone National Park's hottest and most dynamic basins. Airborne high-resolution thermal infrared remote sensing was used to estimate radiometric temperatures within NGB and allow for the estimation of the spatial and temporal distribution of surface temperatures and the heat flow budget. The airborne monitoring occurred in consecutive years 2008-2012 allowing for the temporal comparison of heat budget in NGB. Airborne thermal infrared images in the 8-12 µm bands with 1-m resolution were acquired using a FLIR SC640 scanner. Digital multispectral images in the green (0.57 μm), red (0.65 μm), and near infrared (0.80 μm) bands were also acquired to classify the terrain cover and support the atmospheric and emissivity correction of the thermal images. The airborne images were taken in the month of September on selected days with similar weather and under clear sky conditions. In the winter of 2012, images were also taken in March to compare the effect of the cold weather and snow cover on the heat budget. Consistent methods were used to acquire and process the images each year to limit the potential variability in the results to only the variability in the hydrothermal system. Data from radiation flux towers installed within the basin were used to compare with airborne radiometric surface temperatures and compensate for residual solar heating in the imagery. The presentation will discuss the different mechanisms involved in

    In 1940, during his second year of medical training, Jim Tanner expressed the desire to work, 'where physiology, psychology and sociology meet'. His subsequent exposure to the breadth of an American medical education and to the social and economic environment of post-war Europe distilled his belief in the importance of viewing the human in a broad context. Following his visits to the American longitudinal growth studies in 1948. Jim's dreams of a broad scientific discipline that incorporated both the biology and ecology of the human were strengthened by an inspirational group of embryonic human biologists with whom he developed '… the new Human Biology …' from the '… Physical Anthropology of old…'. With Jo Weiner, Derek Roberts, Geoffrey Harrison, Arthur Mourant, Nigel Barnicot and Kenneth Oakley, Jim was to form the Society for the Study of Human Biology in 1958. The development of human biology over the next 50 years was shaped by the expertise and diversity of that group of visionary scientists who conceived the scientific discipline of 'human biology' in which biology, behaviour and social context define the human species.

    The Jim Bridger Mine is located in southwestern Wyoming, 20 miles north of Rock Springs. Currently, the mine disturbs approximately 100 ac/yr. The mine is situated in the Red Desert, a region used primarily as winter range for sheep. The terrain is rolling, with draws and buttes that are typical of southwestern Wyoming. Precipitation varies between six and eight inches anually. Vegetation is sparse and consists mainly of shrubs and some native grasses, of which saltbush (Atriplex) and sagebrush (Artemesia) are dominant. Four subprojects have been initiated addressing the problems associated with vegetative response to stressed environments, water availability in reclaimed spoils, refaunation dynamics, and topsoil reapplication. A native and a mine spoil site were selected which have a similar slope and aspect. The treatments in the mine spoils include stored topsoil applied over minespoils, native topsoil applied over minespoils (i.e., no storage period), and straw mulch applied over the native topsoil on minespoils.

    Dissolved noble gas concentrations in springs are used to investigate boiling of hydrothermal water and mixing of hydrothermal and shallow cool water in the Norris Geyser Basin area. Noble gas concentrations in water are modeled for single stage and continuous steam removal. Limitations on boiling using noble gas concentrations are then used to estimate the isotopic effect of boiling on hydrothermal water, allowing the isotopic composition of the parent hydrothermal water to be determined from that measured in spring. In neutral chloride springs of the Norris Geyser Basin, steam loss since the last addition of noble gas charged water is less than 30% of the total hydrothermal discharge, which results in an isotopic shift due to boiling of ?? 2.5% ??D. Noble gas concentrations in water rapidly and predictably change in dual phase systems, making them invaluable tracers of gas-liquid interaction in hydrothermal systems. By combining traditional tracers of hydrothermal flow such as deuterium with dissolved noble gas measurements, more complex hydrothermal processes can be interpreted. ?? 2010 Elsevier B.V.

    This article, prepared from remarks made at the presentation of the James Flack Norris Award for 2001, offers some thoughts about how to enhance classroom and laboratory teaching. Many good practices, as well as behavior to avoid, can be obtained by recalling our own experiences as students and by analyzing the presentation styles of visiting speakers. Other qualities of effective teaching include (a) punctuality, (b) thorough preparation, (c) acquiring and sustaining contact with your class, (d) dealing with student questions that you cannot immediately answer, and (e) being serious and professional, yet compassionate and occasionally humorous. Ultimately, attitude is everything in teaching.

  15. Creativity, alcohol and drug abuse: the pop icon Jim Morrison.

    Science.gov (United States)

    Holm-Hadulla, Rainer M; Bertolino, Alina

    2014-01-01

    Alcohol and drug abuse is frequent among performers and pop musicians. Many of them hope that alcohol and drugs will enhance their creativity. Scientific studies are scarce and conclusions limited for methodological reasons. Furthermore, extraordinary creativity can hardly be grasped by empirical-statistical methods. Thus, ideographic studies are necessary to learn from extraordinarily creative persons about the relationship of creativity with alcohol and drugs. The pop icon Jim Morrison can serve as an exemplary case to investigate the interrelation between alcohol and drug abuse and creativity. Morrison's self-assessments in his works and letters as well as the descriptions by others are analyzed under the perspective of creativity research. In the lyrics of Jim Morrison and in biographical descriptions, we can see how Jim Morrison tried to cope with traumatic events, depressive moods and uncontrolled impulses through creative activities. His talent, skill and motivation to write creatively were independent from taking alcohol and drugs. He used alcohol and drugs to transgress restrictive social norms, to broaden his perceptions and to reinforce his struggle for self-actualization. In short, his motivation to create something new and authentic was reinforced by alcohol and drugs. More important was the influence of a supportive group that enabled Morrison's talents to flourish. However, soon the frequent use of high doses of alcohol and drugs weakened his capacity to realize creative motivation. Jim Morrison is an exemplary case showing that heavy drinking and the abuse of LSD, mescaline and amphetamines damages the capacity to realize creative motivation. Jim Morrison is typical of creative personalities like Amy Winehouse, Janis Joplin, Brian Jones and Jimmy Hendrix who burn their creativity in early adulthood through alcohol and drugs. We suppose that the sacrificial ritual of their decay offers some benefits for the excited spectators. One of these is the

    Familial exudative vitreoretinopathy (FEVR) is a disorder characterized by abnormal vascularization of the peripheral retina affecting both the retina and the vitreous body. This is a bilateral disorder and leads to a clinical phenotype resembling retinopathy of prematurity, but affected individuals experience a normal gestational period, and they do not have a history of oxygen therapy. Manifestations of the disorder may include retinal folds, retinal traction, sub- or intraretinal exudates, and in severe cases enophthalmos or phthisis ultimately leading to blindness. Autosomal dominant and X-linked patterns of segregation have been reported. We studied a large three-generation family in which FEVR segregated as an X-linked recessive trait. The Norrie gene was examined because of a prior report of mutation in this gene in a small X-linked FEVR family. Exons 1-3 of the Norrie gene were amplified and screened for mutations by single stranded conformational analysis. A variant conformer of exon 3 was observed in an affected male and in combination with the normal conformer in an obligate carrier female. Sequence analysis revealed a G{r_arrow}T transversion destroying an MspI restriction site. The mutation was present in all affected males, and all obligate carrier females were heterozygous for the mutation. The mutation was not present in unaffected males or in 108 randomly selected normal females. The G{r_arrow}T mutation leads to the substitution of a hydrophobic leucine residue for the positively charged arginine normally present at position 121 of the Norrie gene product. This study confirms that mutation in the Norrie gene can lead to the FEVR phenotype and the existence of allelic heterogeneity.

  2. Expression of the Norrie disease gene (Ndp) in developing and adult mouse eye, ear, and brain

    2011-01-01

    The Norrie disease gene (Ndp) codes for a secreted protein, Norrin, that activates canonical Wnt signaling by binding to its receptor, Frizzled-4. This signaling system is required for normal vascular development in the retina and for vascular survival in the cochlea. In mammals, the pattern of Ndp expression beyond the retina is poorly defined due to the low abundance of Norrin mRNA and protein. Here we characterize Ndp expression during mouse development by studying a knock-in mouse that carries the coding sequence of human placental alkaline phosphatase (AP) inserted at the Ndp locus (NdpAP). In the CNS, NdpAP expression is apparent by E10.5 and is dynamic and complex. The anatomically delimited regions of NdpAP expression observed prenatally in the CNS are replaced postnatally by widespread expression in astrocytes in the forebrain and midbrain, Bergman glia in the cerebellum, and Müller glia in the retina. In the developing and adult cochlea, NdpAP expression is closely associated with two densely vascularized regions, the stria vascularis and a capillary plexus between the organ of Corti and the spiral ganglion. These observations suggest the possibility that Norrin may have developmental and/or homeostatic functions beyond the retina and cochlea. PMID:21055480

    King, Thomas L.

    Full Text Available Abstract: A nineteenth-century American actor named Thomas Rice was sensationally popular as a blackface character named Jim Crow. His popularity is credited with giving birth to blackface minstrelsy as others began to imitate him in the hope of emulating his success. Rices Jim Crow provided a name for laws and customs designed to repudiate the emancipation of African slaves. Blackface minstrelsy staged an idealized version of slave life on a southern plantation. Paradoxically, as blackface revoked the emancipation of slaves on stage, it emancipated the American theatre from its British origins and its audience of recently immigrated laborers from a low social position. It even occasionally performed an ironic reversal of the subaltern status of the very African slaves whose freedom by proclamation and constitutional amendment the performance sought to negate. Contradictions in the history of blackface performance in the United States stage American anxieties about race, class, emancipation, and the very construction of the concepts of blackness and whiteness. Resumen: En el siglo XIX, Thomas Rice, un actor estadounidense, ganó mucha fama haciendo el papel de un personaje cuya cara estaba pintada de negro con el nombre Jim Crow. Se le da crédito a Rice la creación de grupos de actores que se pintaron la cara de negro (un estilo denominado blackface que luego otros se pusieron a imitarlos con la esperanza de emular su éxito. El Jim Crow de Rice dio nombre a una serie de leyes y costumbres diseñadas para repudiar la emancipación de esclavos africanos. Los espectáculos de los actores en blackface representaron una versión idealizada de la vida de los esclavos en una hacienda sureña. Paradójicamente, mientras el blackface revocó la emancipación de los esclavos sobre el escenario, emancipó el teatro estadounidense de sus orígenes británicas y su público que consistía en obreros inmigrantes de baja clase social.

    2013-07-01

    This study outlines the development and validation of a new 4-dimensional job insecurity measure (JIM). Items were generated from interviews with Australian employees facing an objective threat of job loss. The measure was then validated on a North American sample of 1,004 respondents. Exploratory and confirmatory factor analyses (EFA and CFA) with tests of sample invariance supported an 18-item measurement model consisting of 4 correlated but distinct subscales of insecurity: Job Loss, Job Changes, Marginalization, and Organizational Survival. The results indicate convergent and discriminant validity as well as high internal consistency for the instrument. Significant associations with psychological well-being (job related affective well-being, job satisfaction) and organizational attitudes (organizational commitment, trust in management, intention to resign) established the criterion-related validity of each subscale. These findings support the use of the instrument in academic and applied settings.

    1977-02-01

    Four subprojects have been developed for the Jim Bridger Mine near Rock Springs, Wyoming. This research addresses the problems associated with vegetative response to stressed environments, water availability in reclaimed spoils, refaunation dynamics, and snowpack management for reclamation. A fifth project, soil microbiota recovery dynamics, will also be done at the mine site. Research on vegetative adaptations to stressed ecosystems concentrates on productivity, population dynamics and energy allocation strategies as indicators of plant response to stress. Water availability studies address erosion and spoil moisture characteristics of the native ecosystem and selected reclamation treatments. Design snowfence systems studies will develop methodologies to maximize the amount of the precipitation which is available to vegetation. Animal species composition and density on revegetated areas are also being examined. Wildlife studies are also investigating the impacts of small mammals on revegetation. The microbiological component of topsoil is being investigated in stored and native topsoil. These experiments are designed to provide insight into the reclamation of communities, not just revegetation of mine spoils.

  14. An economic analysis of the Jim Bridger Power Plant carbon dioxide mineralization process

    Science.gov (United States)

    Christensen, Mikol Hans

    Concerns for rising levels of CO2 in the atmosphere have lead to a myriad of schemes to reduce emissions. Many of these are complicated, expensive, and untried. Coal-fired electrical generation accounts for about 49 percent of U.S. electricity generation. Shifting generation capacity away from coal is the goal of many, yet as this statistic shows, the U.S. has a heavy dependency on coal-fired base-load generation. What is needed is a way to retrofit existing coal fired power plants to mitigate at least some of the giga-tonnes of CO2 released annually. Carbon Capture and Storage in association with greenhouse gases are a major concern in the world today. This thesis is an outgrowth of a research partnership between the University of Wyoming and the Jim Bridger Power Plant (Rocky Mountain Power) to develop a process for capture and mineralization of flue gas carbon dioxide (CO 2) using an accelerated mineral carbonization process with fly ash particles as the absorbent. This process may have several advantages over other approaches because it is an environmentally acceptable, single step process occurring at near ambient pressures and temperatures that can compliment conventional CCS processes. In addition the use of fly ash particles as an absorbent avoids the costs of processing or engineering an absorbent. The purpose of this thesis is to evaluate the capture costs and economic feasibility of the mineralization process. Two models were used to estimate the capture costs and economic feasibility of the Jim Bridger Power Plant CO2 Mineralization Project (JBP). The first was a cost of capture model which was used to estimate CO2 capture costs and how changes in the CO2 to ash capture ratio and quantities of CO2 captured affect capture costs. The second was a financial feasibility model which considered the time value of money. This second model considered the net present value (NPV) and internal rate of return (IRR) for the process using different pricing scenarios

  16. Magnetospheric Plasma Physics : the Impact of Jim Dungey’s Research

    CERN Document Server

    Southwood, David; Mitton, Simon

    2015-01-01

    This book makes good background reading for much of modern magnetospheric physics. Its origin was a Festspiel for Professor Jim Dungey, former professor in the Physics Department at Imperial College on the occasion of his 90th birthday, 30 January 2013. Remarkably, although he retired 30 years ago, his pioneering and, often, maverick work in the 50’s through to the 70’s on solar terrestrial physics is probably more widely appreciated today than when he retired. Dungey was a theoretical plasma physicist. The book covers how his reconnection model of the magnetosphere evolved to become the standard model of solar-terrestrial coupling. Dungey’s open magnetosphere model now underpins a holistic picture explaining not only the magnetic and plasma structure of the magnetosphere, but also its dynamics which can be monitored in real time. The book also shows how modern day simulation of solar terrestrial coupling can reproduce the real time evolution of the solar terrestrial system in ways undreamt of in 1961 w...

  17. Love stories can be unpredictable: Jules et Jim in the vortex of life.

    Dercole, Fabio; Rinaldi, Sergio

    2014-06-01

    Love stories are dynamic processes that begin, develop, and often stay for a relatively long time in a stationary or fluctuating regime, before possibly fading. Although they are, undoubtedly, the most important dynamic process in our life, they have only recently been cast in the formal frame of dynamical systems theory. In particular, why it is so difficult to predict the evolution of sentimental relationships continues to be largely unexplained. A common reason for this is that love stories reflect the turbulence of the surrounding social environment. But we can also imagine that the interplay of the characters involved contributes to make the story unpredictable-that is, chaotic. In other words, we conjecture that sentimental chaos can have a relevant endogenous origin. To support this intriguing conjecture, we mimic a real and well-documented love story with a mathematical model in which the environment is kept constant, and show that the model is chaotic. The case we analyze is the triangle described in Jules et Jim, an autobiographic novel by Henri-Pierre Roché that became famous worldwide after the success of the homonymous film directed by François Truffaut.

    2016-05-01

    Full Text Available Le raccolte Platero y yo e Diario de un poeta reciencasado nate, come ricorda lo stesso Jiménez, da reali occasioni autobiografiche, e pubblicate nello stesso anno (1917 costituiscono uno snodo importante non solo nella produzione lirica del grande poeta di Moguer. In esse la novità è anzitutto di tipo formale: sperimentando con sempre maggiore consapevolezza il genere del poema in prosa, e contaminandolo, come si vede in modo particolare nel Diario, con la versificazione libera, Jiménez avvia una seconda fase della sua ricerca poetica. A quale tradizione lirica, in primo luogo ispanica, e poi europea, è possibile ascrivere l’ibridazione dei generi poetici sperimentata da Jiménez? Quale finalità lirica esorta il poeta ad adoperare il poema in prosa per narrare di personali esperienze biografiche? Che tipo di soggettività veicola questo genere-non genere della modernità? E più in generale: è possibile che l’autore andaluso attribuisca al poema in prosa, oltre che una funzione lirico-narrativa, precipui contenuti metapoetici? Nel presente studio si proverà a rispondere a tali interrogativi a partire dallo studio delle due opere menzionate, che hanno il vantaggio di definirsi come due campioni pressocché coevi dell’ibridismo del poeta. L’ipotesi è che in Platero e nel Diario Jiménez si faccia portavoce di una sorta di personale bilancio, non solo rispetto alla tradizione modernista ispanica, ma anche a quella europea. In controtendenza con quest’ultima, che trova il suo archetipo negli Spleen baudelairiani, per l’autore andaluso l’ibridazione dei generi lirici non è una modalità di rappresentazione della disarticolazione del moderno, ma al contrario, e piuttosto in linea con la generazione lirica ispanica a cui egli appartiene, di affermazione di una visione di un mondo coeso e denso di ethos.} Jiménez’s collections of poems Platero y yo and Diario de un poeta reciencasado, written after real

    2005-01-01

    A summary of advances in residual strength analyses methods for metallic structures that were realized under the leadership of Dr. James H. Starnes, Jr., is presented. The majority of research led by Dr. Starnes in this area was conducted in the 1990's under the NASA Airframe Structural Integrity Program (NASIP). Dr. Starnes, respectfully referred to herein as Jim, had a passion for studying complex response phenomena and dedicated a significant amount of research effort toward advancing damage tolerance and residual strength analysis methods for metallic structures. Jim's efforts were focused on understanding damage propagation in built-up fuselage structure with widespread fatigue damage, with the goal of ensuring safety in the aging international commercial transport fleet. Jim's major contributions in this research area were in identifying the effects of combined internal pressure and mechanical loads, and geometric nonlinearity, on the response of built-up structures with damage. Analytical and experimental technical results are presented to demonstrate the breadth and rigor of the research conducted in this technical area. Technical results presented herein are drawn exclusively from papers where Jim was a co-author.

  12. Characterizing Thermal features in Norris Basin, Yellowstone National Park, Using Multi- spectral Remote Sensing Data and Dynamic Calibration Procedures

    Hardy, C. C.; Queen, L. P.; Heasler, H. P.; Jaworowski, C.

    2007-12-01

    A thermal infrared remote sensing project was implemented to develop methods for identifying, classifying, and mapping thermal features. This study is directed at geothermal features, with the expectation that new protocols developed here will apply to the wildland fire thermal environment. Airborne multi-spectral digital imagery were acquired over the geothermally active Norris Basin region of Yellowstone National Park, USA. Two image acquisitions were flown, with one acquisition near solar noon and the other at night. Raw data from the five sensors were uncalibrated, so a vicarious calibration procedure was developed to compute reflectance for the visible and NIR bands using an independently calibrated hyperspectral dataset. Calibration of the thermal sensor band utilized a dynamic, in-scene calibration procedure that exploited natural, pseudo-invariant thermal reference targets instrumented with in situ kinetic temperature recorders. The calibrated reflectance and radiant temperature data from each acquisition were processed and analyzed to develop a suite of thermal attributes, including radiant temperatures, a daytime-nighttime temperature difference (DeltaT), albedo, an albedo derivative (one minus albedo), and apparent thermal inertia (ATI). The albedo terms were computed using a published weighed-average albedo algorithm based on ratios of the narrowband red and near-infrared (NIR) reflectances to total solar irradiance for the respective red and NIR bandpasses. The weighing factors for each band were the proportion of total solar irradiance incident on the surface within each segment represented by a respective bandpass. In the absence of verifiable "truth," a step-wise chain of unsupervised classification and multivariate analysis exercises was performed, drawing heavily on "fuzzy truth" to assess the quality, efficiency, and efficacy of classification procedures and results. A final classification synthesizes a "geothermal phenomenology" comprised of

We demonstrate that Metallosphaera yellowstonensis MK1, a facultative autotrophic archaeon isolated from a hyperthermal acidic hydrous ferric oxide (HFO) spring in Norris Geyser Basin, excretes formaldehyde during autotrophic growth. To determine the fate of formaldehyde in this low organic carbon environment, we incubated native microbial mat (containing M. yellowstonensis) from a HFO spring with (13)C-formaldehyde. Isotopic analysis of incubation-derived CO2 and biomass showed that formaldehyde was both oxidized and assimilated by members of the community. Autotrophy, formaldehyde oxidation, and formaldehyde assimilation displayed different sensitivities to chemical inhibitors, suggesting that distinct sub-populations in the mat selectively perform these functions. Our results demonstrate that electrons originally resulting from iron oxidation can energetically fuel autotrophic carbon fixation and associated formaldehyde excretion, and that formaldehyde is both oxidized and assimilated by different organisms within the native microbial community. Thus, formaldehyde can effectively act as a carbon and electron shuttle connecting the autotrophic, iron oxidizing members with associated heterotrophic members in the HFO community.

    1997-10-01

    Full Text Available opresente ensaio oferece uma exegese crítica dos sete livros que, até o final de 1997, o teórico e crítico britânico Christopher Norman dedicou ao pós-modernismo, considerando-se que a temática de Norris é a teoria pósmodernista, não os artefatos culturais ou processos pósmodernistas pelos quais ele demonstra pouco interesse. Nessa trajetória, são entrelaçados os fios de diversas questões: o entendimento de Norris do pós-modernismo; as objeções que ele faz à teoria pós-modernista; o teor de sua discordância de pensadores como Baudrillard com relação à Guerra do Golfo; a nota de desalento que pauta sua visão do pós-modernismo; o impacto do contexto político de direita de Margaret Thatcher sobre sua visão pessimista dos intelectuais pós-modernistas no início da década. Sobretudo, o ensaio rastreia a crítica reiterada de Norris à excessiva extensão conferida à lingüística saussureana, na sua opinião, a raiz de um mal-elaborado "relativismo cultural", bem como seu amplo comentário sobre o afastamento de Michel Foucault do pensamento de Kant. Norris crê que esse encontro ilustra, de forma exemplar, o afastamento pós-modernista dos valores iluministas de verdade, crítica e razão universal, cujo corolário, para ele, é a eliminação de qualquer vinculação, baseada em princípios, entre a prática intelectual e o domínio ético-político. O ensaio oferece, paralelamente, um número de críticas a Norris (inclusive seu hábito de processar diversas posições numa máquina teórica abstrata e imperdoável, aiJ ressaltar as muitas alternativas à teoria pós-modernista que ele explora (filosofias pós-analíticas do significado, filosofia da ciência, realismo causal, a desconstrução de Derrida e de Man.

  4. Tourism and the Hispanicization of race in Jim Crow Miami, 1945-1965.

    Science.gov (United States)

    Rose, Chanelle N

    2012-01-01

    This article examines how Miami's significant presence of Anglo Caribbean blacks and Spanish-speaking tourists critically influenced the evolution of race relations before and after the watershed 1959 Cuban Revolution. The convergence of people from the American South and North, the Caribbean, and Latin America created a border culture in a city where the influx of Bahamian blacks and Spanish-speakers, especially tourists, had begun to alter the racial landscape. To be sure, Miami had many parallels with other parts of the South in regard to how blackness was understood and enforced by whites during the first half of the twentieth century. However, I argue that the city's post-WWII meteoric tourist growth, along with its emergence as a burgeoning Pan-American metropolis, complicated the traditional southern black-white dichotomy. The purchasing power of Spanish-speaking visitors during the postwar era transformed a tourist economy that had traditionally catered to primarily wealthy white transplanted Northerners. This significant change to the city's tourist industry significantly influenced white civic leaders' decision to occasionally modify Jim Crow practices for Latin American vacationers. In effect, Miami's early Latinization had a profound impact on the established racial order as speaking Spanish became a form of currency that benefited Spanish-speaking tourists—even those of African descent. Paradoxically, this ostensibly peculiar racial climate aided the local struggle by highlighting the idiosyncrasies of Jim Crow while perpetuating the second-class status of native-born blacks.

    Objective To detect the pathogenic mutation in a Chinese family with Norrie disease.Methods Clinical diagnosis was based on familial history,clinical sign and B ultrasonic examination.Peripheral blood samples were obtained from all available members in a Chinese family with Norrie disease.Genomic DNA was extracted from lymphocytes by the standard SDS-proteinase K-phenol/chloroform method.Two coding exons and all intron-exon boundaries of the NDP gene were PCR amplified using three pairs of primers and subjected to automatic DNA sequence.The causative mutation was confirmed by restriction enzyme analysis and genotyping analysis in all members.Results Sequence analysis of NDP gene revealed a missense mutation c.220C > T (p.Arg74Cys ) in the proband and his mother. Further mutation identification by restriction enzyme analysis and genotyping analysis showed that the proband was homozygote of this mutation.His mother and other four unaffected members ( Ⅲ3,Ⅳ4,Ⅲ5 and Ⅱ2) were carriers of this mutation.The mutant amino acid located in the C-terminal cystine knot-like domain,which was critical motif for the structure and function of NDP. Conclusion A NDP missense mutation was identified in a Chinese family with Norrie disease.%目的 对我国诺里病一家系进行致病基因突变的鉴定,确定其家系中是否存在NDP基因突变.方法 基因家系研究.发现一个3代均患有诺里病的家系,共13人,患者3人,现存患者仅先证者1人,为20月龄男孩.根据诺里病家族史、临床体征及眼科B超检查对患者进行临床诊断;采集该家系成员外周血标本,常规提取基因组DNA;设计并合成3对特异性引物,通过PCR扩增NDP基因的外显子及外显子与内含子交界区,PCR产物直接测序;通过PCR产物限制性内切酶分析和基因型分析对家系所有13名成员进行突变鉴定.结果 基因测序结果显示先证者及其母亲均具有NDP基因突变c.220C> T(p.Arg74Cys),且先证者为

    Using data from 92 interviews, this article examines the narratives of African Americans' experiences as children and young adults during Jim Crow in the Southeast and Southwest. It gives voice to the realities of sexual assaults committed by ordinary White men who systematically terrorized African American families with impunity after the post-Reconstruction south until the 1960s. The interviewees discuss the short- and long-term impact of physical, mental, emotional, and sexual assaults in their communities. We discuss the top four prevalent themes that emerged related to sexual assault, specifically (a) the normalization of sexual assaults, (b) protective measures to avoid White violence, (c) the morality of African American women, and (d) the long-term consequences of assaults on children. © The Author(s) 2016.

    Full Text Available This paper looks at the genesis and development of the Jama’ah Islah Malaysia (JIM, a modernist-reformist Islamist organisation that today has played a vital and visible role in the political landscape of Malaysian politics. Little is known about the early genesis of JIM, and how it began in the 1970s and 1980s as a student-based cadre organisation, created by Malaysian Muslim students studying abroad in Europe and North America. JIM’s roots therefore lie in the Islamic Representative Council (IRC that was a semi-underground student-cadre movement that was created outside Malaysia, and which aimed to bring about the Islamisation of Malaysian society through the process of social and political mobilisation. Working through the archives of JIM today and interviewing the foundermembers of JIM and the IRC, this paper is the first historical account of the formation and development of IRC and JIM to be published.

    La lepra es una enfermedad que se caracteriza por la insidia de su presencia, su lenta evolución y la progresiva incapacidad que en sus víctimas causa.

    Esto y el temor que ha infundido desde tiempos bíblicos, han hecho que ante ella se haya mantenido una actitud ambivalente de negación hasta donde es posible y de rechazo irracional a quien la padece, por temor al contagio.

    Ejemplo de ello es el aura de sagrado misterio que envuelve la leyenda de los padecimientos del Adelantado don Gonzalo Jiménez de Quesada (1509-1579, conquistador del Nuevo Reino de Granada y fundador de Santafé de Bogotá en el año de 1538, muerto a la edad, avanzada para la época, de setenta años.

    No se puede afirmar, en forma definitiva, que el conquistador fuera leproso. Se acepta, acogiendo el argumento de autoridad que tiene el primer historiador médico entre nosotros, don Pedro María Ibáñez, quien escribió en 1884, en las Memorias para la Historia de la Medicina en Santa Fe, que en “1579 falleció en la ciudad de Mariquita, y de mal de lepra o elefancía de los

    1983-01-01

    Full Text Available Equally as demanding of others as he was of himself, Juan Ramón Jiménez conceived of literary criticism as a serious and exacting task. The critic and the poet, standing side by side, are devoted to complementary activities of mutual enrichment. However fragmentary and partial the critical opinions of Juan Ramón may be (also outspoken and polemical in nature, they are invaluable as a personal historical and aesthetic guide to about fifty or sixty years of Hispanic literary development (1900-1960. Not to take them into account is to fail to recognize a highly important aspect of his total artistic personality. These varied critical texts are a product of a first rate intelligence and the sensibility of a writer of consummate discrimination who was endowed not only with an excellent memory but also a very special talent for appreciating the authentic. Juan Ramón as a critic is quick to praise (San Juan, Bécquer, Dario, Unamuno and Machado and at the same time strong in his censure of certain contemporaries. Several recently collected volumes of miscellaneous critical materials have resolved the bibliographical muddle for the initial study of this fundamental aspect of the poet, but still particularly important are the expressionistic portraits of Españoles de tres mundos , longer tributes to Valle, Ortega and Villaespesa as well as the extensive lectures delivered in his latter years. Examination of these pages gives us an historical and creative overview of the period in which he lived and worked in addition to original considerations about the evolution of Hispanic poetry. Of course, one of the constant focal points of his literary criticism was the modernist epoch of his early days, a movement or attitude which he considered to be a modern twentieth century renaissance. Together with detailed study of these two areas of historical and aesthetic nature, in the ensuing pages some conclusions are pointed out as to the essence of poetry

    Directory of Open Access Journals (Sweden)

    Paula Murphy

    2009-03-01

    Full Text Available This article analyses Jim Sheridan’s film In America (2002, arguing that the American location reflects back imaginary images of Ireland to its Irish audience, in a manner similar to the mechanism described in Lacan’s discussion of his experiment of the inverted bouquet, which he uses to illustrate the three registers of the human psyche. It explores imaginary, symbolic and real dimensions of identity as they are articulated in the film, showing that, as in Lacan’s experiment, the symbolic dimension, which equates with the position of the human subject as social being, is the most powerful structuring force.  In Sheridan’s film, this dimension is embodied in Steven Spielberg’s film ET, a fictional narrative that allows Johnny, the father of the family, to articulate his grief and begin a new life.  Further, Sheridan’s film suggests that America is the imaginary locus of contemporary Irish identity, and that it can be understood as analogous to the spherical mirror of Lacan’s experiment.

He occupied important positions in the political administration of the Protectorate (as director of the political section of Melilla’s Oficina Central de Intervenciones and a senior official in the Department of Indigenous Affairs; he was fluent in Arab and Tamazight, and gained a sound knowledge of the geography of the Rif mountains. His military career, in which he achieved the rank of lieutenant colonel, was characterized by his strictly professional attitude. He was one of the few career officers in Africa who were faithful to Spain’s republican government and who did not participate in the military uprising of 1936. This discussion of his career brings into question some well-established ideas concerning Spanish colonial policy in Morocco.

  3. Relativity in Transylvania and Patusan: Finding the roots of Einstein's theories of relativity in "Dracula" and "Lord Jim"

    Science.gov (United States)

    Tatum, Brian Shane

    This thesis investigates the similarities in the study of time and space in literature and science during the modern period. Specifically, it focuses on the portrayal of time and space within Bram Stoker's Dracula (1897) and Joseph Conrad's Lord Jim (1899-1900), and compares the ideas presented with those later scientifically formulated by Albert Einstein in his special and general theories of relativity (1905-1915). Although both novels precede Einstein's theories, they reveal advanced complex ideas of time and space very similar to those later argued by the iconic physicist. These ideas follow a linear progression including a sense of temporal dissonance, the search for a communal sense of the present, the awareness and expansion of the individual's sense of the present, and the effect of mass on surrounding space. This approach enhances readings of Dracula and Lord Jim, illuminating the fascination with highly refined notions of time and space within modern European culture.

    Full Text Available José Jiménez Lozano is a unique writer in the Hispanic literary scene of these last decades. His work is vast and diverse, and this initial observation does not escape his narrative, which genre the write demonstrates more prolifically. Despite the apparent diversity, there is outstanding unity underlying Jiménez Lozano´s entire work. This unity lies not only on the constant return to the same matters, but also on the approaches or the reasons, from which his literary work begins. The writer reflects over his work and lets his ideas expand through the diverse manifestations of his ideas on prose. It is a talk about the rhetorical writing of this article, valuing the coherent existence between reflection and literary practice.José Jiménez Lozano es un escritor singular dentro del panorama literario hispánico de las últimas décadas. Su obra es vasta y diversa y a esta observación inicial no escapa su narrativa, género en el que el escritor se muestra más prolífico. A pesar de la diversidad aparente, existe una notable unidad subyacente a toda la obra de Jiménez Lozano. Esta unidad reposa no sólo sobre el regreso constante a unos mismos asuntos sino también sobre los planteamientos o fundamentos de los que parte su creación literaria. El escritor reflexiona sobre su labor y deja diseminado, a través de las diversas manifestaciones de su prosa de ideas, un discurso sobre la escritura que este artículo sintetiza, valorando, asimismo, la coherencia existente entre esta reflexión y la praxis literaria.

    2012-06-01

    Full Text Available In the manuscript of El virtuoso discreto [The Virtuous Discreet Man], the humanist and grammarian Bartolomé Jiménez Patón reveals himself to be a zealous defender of orthodoxy. This work, formulated as a complement to his pedagogical duties as Professor of Eloquence, manifests its author’s purpose of participating in the religious controversy of his times, particularly in those fundamental aspects that distance Tridentine Catholicism from Lutheranism. Thus, part of the work is dedicated to a reflection on the concept of the Church, free will and theological justification, the doctrine of which was central to the development of the Council of Trent and the seven sacraments. No less important in this manuscript is Patón’s impassioned condemnation of illuministic heresy, the only genuinely Spanish doctrine of this sort in the Modern Age, whose members were also known in Spanish as alumbrados or agapetas.En el ms. de El virtuoso discreto, el humanista y gramático Bartolomé Jiménez Patón se muestra como un receloso defensor de la ortodoxia. La obra, concebida como un complemento a su enseñanza en su cátedra de Elocuencia, evidencia el propósito de su autor de participar en la controversia religiosa de su tiempo, particularmente en aquellos aspectos fundamentales que distancian al catolicismo tridentino del luteranismo. Así, parte de la obra se ocupa en reflexionar sobre el concepto de Iglesia, el libre albedrío y la justificación, cuya doctrina fue central en el desarrollo del concilio de Trento, y los siete sacramentos. No menor importancia presenta su apasionada condena de la herejía iluminista, la única genuinamente española en la Edad Moderna, cuyos miembros fueron también conocidos como alumbrados o agapetas.

    Joseph Conrad is one of the most esteemed English writers of the 20th century. Conrad' s novels plumb the depth of the human soul and propose profound moral questions. Lord Jim is a great example to showcase Conrad' s concern about human nature. With the aid of Lacan' s theory of mirror stage, this paper aims to analyze the formation of Jim' s ideal-ego and the reasons for his failed pursuit of the ideal-ego.%约瑟夫·康拉德享誉20世纪英国文坛及世界文坛。他的众多小说关照到了人性的深度,提出深刻的道德问题,其代表作《吉姆爷》正是这样一部作品。它检视了人性的阴暗面,塑造了一个挫败的英雄形象-吉姆。吉姆的一生都在追逐他的英雄梦,渴望实现他的“理想自我”。本文试图用拉康的镜像理论来分析主人公吉姆的理想自我的形成以及最终毁灭的原因。

  11. Physical and hydrochemical evidence of lake leakage near Jim Woodruff lock and dam and ground-water inflow to Lake Seminole, and an assessment of karst features in and near the lake, southwestern Georgia and northwestern Florida

    Torak, Lynn J.; Crilley, Dianna M.; Painter, Jaime A.

    2006-01-01

    Hydrogeologic data and water-chemistry analyses indicate that Lake Seminole leaks into the Upper Floridan aquifer near Jim Woodruff Lock and Dam, southwestern Georgia and northwestern Florida, and that ground water enters Lake Seminole along upstream reaches of the lake's four impoundment arms (Chattahoochee and Flint Rivers, Spring Creek, and Fishpond Drain). Written accounts by U.S. Army Corps of Engineers geologists during dam construction in the late 1940s and early 1950s, and construction-era photographs, document karst-solution features in the limestone that comprise the lake bottom and foundation rock to the dam, and confirm the hydraulic connection of the lake and aquifer. More than 250 karst features having the potential to connect the lake and aquifer were identified from preimpoundment aerial photographs taken during construction. An interactive map containing a photomosaic of 53 photographic negatives was orthorectfied to digital images of 1:24,000-scale topographic maps to aid in identifying karst features that function or have the potential to function as locations of water exchange between Lake Seminole and the Upper Floridan aquifer. Some identified karst features coincide with locations of mapped springs, spring runs, and depressions that are consistent with sinkholes and sinkhole ponds. Hydrographic surveys using a multibeam echosounder (sonar) with sidescan sonar identified sinkholes in the lake bottom along the western lakeshore and in front of the dam. Dye-tracing experiments indicate that lake water enters these sinkholes and is transported through the Upper Floridan aquifer around the west side of the dam at velocities of about 500 feet per hour to locations where water 'boils up' on land (at Polk Lake Spring) and in the channel bottom of the Apalachicola River (at the 'River Boil'). Water discharging from Polk Lake Spring joins flow from a spring-fed ground-water discharge zone located downstream of the dam; the combined flow disappears into

His aim was to write novels in his capacity as a poet. As a result he wished to create novels as prolongation of his poems.

    2008-03-01

    Full Text Available This paper will examine the recurring theme of death in Jim Sheridan’s work, with particular focus on his 2003 film In America. This theme also links Sheridan’s work to one of his favourite directors, John Ford, whose work In America alludes to. While exploring the theme of death in Sheridan’s films, and how it connects with the work of Ford, this paper will consider responses to In America, the first film to be (partly shot in New York after the attack on the twin towers, in light of the tragedy of 9/11. It raises questions about the problematic positioning of this film by Sheridan and others not just with respect to the events of that day but also in relation to the 1981 hunger strikes in Northern Ireland. Furthermore, it questions the regressive politics involved in the depiction of the central black character in In America, Mateo, particularly as it relates to this theme of death.

    The Holy Bible is an important source of western literature creation. Almost all the western writers' greatly influenced by The Holy Bible. Joseph Conrad is no exception. In Lord Jim, Joseph Conrad innovated tively used the Biblical archetypes, based on the themes of the original sin, expiation and rebirth. With his h spirit, Conrad rewrote the Biblical story of the original sin to disclose humanity' s evil. Yet he went far beyond 1 of expiation and elevated the theme of the novel to a new height, he put forward that human could finally find works are and crearebirth if only they face the misery of life and confess to the God bravely.%《圣经》是西方文学创作的一个源泉,也是康拉德写作的灵感来源。《吉姆爷》一书中,康拉德从原罪主题、赎罪主题以及新生主题三个方面对圣经原型进行了阐释和创新。通过重现圣经的原罪故事,康拉德展示了人类的罪恶也突出了他对人性的关注和理解,他没有仅仅停留在接收惩罚这个层面上,而是把主题上升到勇于接受苦难,积极面对生活的精神层面,认为人类只要对罪真心悔过,最终必将获得新生。

    2012-01-01

    Beginning in July 2003 and lasting through September 2003, the Norris Geyser Basin in Yellowstone National Park exhibited an unusual increase in ground temperature and hydrothermal activity. Using hidden Markov model theory, we identify over five million high-frequency (>15 Hz) seismic events observed at a temporary seismic station deployed in the basin in response to the increase in hydrothermal activity. The source of these seismic events is constrained to within ~100 m of the station, and produced ~3500–5500 events per hour with mean durations of ~0.35–0.45 s. The seismic event rate, air temperature, hydrologic temperatures, and surficial water flow of the geyser basin exhibited a marked diurnal pattern that was closely associated with solar thermal radiance. We interpret the source of the seismicity to be due to the collapse of small steam bubbles in the hydrothermal system, with the rate of collapse being controlled by surficial temperatures and daytime evaporation rates.

  15. I'm Right and You're and Idiot — Jim Hoggan discusses the toxic state of public discourse and how to clean it up, by changing the communication climate

    Hoggan, J. C.

    2016-12-01

    Just as the natural environment can be polluted, so too can public discourse. I'm Right and You're an Idiot: The Toxic State of Public Discourse and How to Clean it Up examines the sorry state of today's public square, showing how polluted, polarized conversations discourage people from taking action on critical issues such as climate change, and demonstrating how we can clear the air and become more powerful and effective communicators. The most urgent environmental threat today is not climate change, species extinction or the declining health of oceans. Author Jim Hoggan says the more pressing problem is resistance to change that results from pollution in the public square. A smog of adversarial rhetoric, propaganda and polarization that comes from all sides, is stifling discussion and our ability to solve problems collectively. Hoggan has investigated this troubling state of public dialogue and in his new book he asks leading intellectuals why, despite overwhelming scientific evidence, so little is being done to address today's critical environmental challenges. As chair of the David Suzuki Foundation and founder of one of Canada's most successful PR firms, he is uniquely positioned to probe this question. During Hoggan's 30 years in crisis management he has dealt with food poisonings, labour disputes, multi-million dollar bank fraud, sawmill explosions, even bodies disappearing from funeral homes. He also authored the bestseller Climate Cover-Up, which took a critical look at science propaganda and the widespread echo chamber of media and think tanks that magnifies it. How do we improve public discourse and curb over-the-top advocacy, corrupt conversations and propaganda. How do we counteract polarization and gridlock? Hoggan sought answers from more than 60 outstanding scholars, ranging from a NASA scientist to deep-sea oceanographer. He tapped the brains of cognitive researchers, political pundits, philosophers, moral psychologists, corporate analysts and

    李菊花; 杨金才

    2016-01-01

    Harvest is Jim Crace’s recent novel.The paper argues that the novel can be categorized as a Gothic,not only because the theme,the characterization,the setting and plotting are traditionally gothical, but because it narrates in contemporary Gothic manifestations.The Gothic narrative helps to eliminate the sex opposition.By characterizing a female “living ghost”,the Gothic violence narrative reveals that the self is split and the “uncanny”is dispersing.The novel connects the present with historical materials to represent contemporary concerns,that is individual and collective anxiety.Meanwhile,it expresses Crace’s community vision by way of reclaiming “wilderness”discourse.%《收获》是英国作家吉姆·克雷斯2013年的新作。《收获》作为一部哥特小说,在主题、人物形象、环境刻画及情节构造等方面均借鉴了哥特传统,同时又融入了一些当代哥特叙事。小说不但试图通过哥特形式,消除性别二元对立,还通过“活体幽灵”的女性哥特暴力话语叙事,揭示主体自我分裂本质为“家”与“非家”暗恐的博弈;不仅拟写并反思历史,书写当代英国社会条件下的种种个体或集体的文化焦虑,还表达了克雷斯试图通过重塑荒野审美话语形成一种社会共同体性建构力量的愿景。

    This is the eighth Quarterly Technical Report for DOE Cooperative Agreement No. DE-FC26-00NT40895. A statement of the project objectives is included in the Introduction of this report. The final biomass co-firing test burn was conducted during this quarter. In this test (Test 14), up to 20% by weight dry switchgrass was comilled with Jim Walters No.7 mine coal and injected through the single-register burner. Jim Walters No.7 coal is a low-volatility, low-sulfur ({approx}0.7% S) Eastern bituminous coal. The results of this test are presented in this quarterly report. Progress has continued to be made in implementing a modeling approach to combine reaction times and temperature distributions from computational fluid dynamic models of the pilot-scale combustion furnace with char burnout and chemical reaction kinetics to predict NO{sub x} emissions and unburned carbon levels in the furnace exhaust. The REI Configurable Fireside Simulator (CFS) is now in regular use. Presently, the CFS is being used to generate CFD calculations for completed tests with Powder River Basin coal and low-volatility (Jim Walters No.7 Mine) coal. Niksa Energy Associates will use the results of these CFD simulations to complete their validation of the NOx/LOI predictive model. Work has started on the project final report.

    A 3-D MicroWave Studio model for the RF drive in the LANSCE DTL tank 4 has been built. Both eigensolver and time-domain modeling are used to evaluate maximal fields in the drive module and RF coupling. The LANSCE DTL tank 4 has recently been experiencing RF problems, which may or may not be related to its replaced RF coupler. This situation stimulated a request by Dan Rees to provide EM modeling of the RF drive in the DTL tank 4 (T4). Jim O'Hara provided a CAD model that was imported into the CST Microwave Studio (MWS) and after some modifications became a part of a simplified MWS model of the T4 RF drive. This technical note describes the model and presents simulation results.

    Justus von Liebig was one of the most vocal proponents of chemistry as the central science. He had a vision of chemistry as a discipline with shifting and overlapping boundaries with many fields, including biology, agriculture, and physics. However, it was not until the advent of scientific instrumentation enabling chemists to measure inorganic and organic materials on the nanogram level that the centrality of chemistry to art and archaeology was recognized. This talk is based on my own experience of that centrality.

Molecular biologists are clearly not listening. Not content with merely inserting the occasional gene into the genome of an existing organism. they are developing a whole new field, Synthetic Biology, which aims to engineer from first principles organisms with desirable, controllable qualities.

    Press release Geneva, 10 August 2016. In a paper published by the journal JHEP today, the MoEDAL experiment at CERN[1] narrows the window of where to search for a hypothetical particle, the magnetic monopole. Over the last decades, experiments have been trying to find evidence for magnetic monopoles at accelerators, including at CERN’s Large Hadron Collider. Such particles were first predicted by physicist Paul Dirac in the 1930s but have never been observed so far. “Today MoEDAL celebrates the release of its first physics result and joins the other LHC experiments at the discovery frontier," says Spokesperson of the MoEDAL experiment, James Pinfold. Just as electricity comes with two charges, positive and negative, so magnetism comes with two poles, North and South. The difference is that while it’s easy to isolate a positive or negative electric charge, nobody has ever seen a solitary magnetic charge, or monopole. If you take a bar magnet and cut it in half, you end up with two smaller bar magnets, ea...

    1997-06-01

    In the early 1980s several prominent scientists left the hallowed halls of respected universities seeking to exploit the revolution occurring in biology in an environment devoid of the bureaucratic and political confines of academia. The emergence of the biotechnology industry has been marked by both spectacular failures and success stories. Genentech was founded in 1976 by biochemist Herbert Boyer and venture capitalist Robert Swanson and went public in 1980. In 1995 Genentech merged with Roche Holdings Ltd., of Basel Switzerland. Distinguished from other biotech companies by the varied array of products it has brought to market, Genentech has also developed a unique corporate culture embodying many traditional academic values. Just as Genentech went public in 1980, Arthur D. Levinson, PhD, finished a post-doctoral appointment in Michael Bishop's lab at the University of California, San Francisco. Despite the disapproval of colleagues, he joined the fledgling company as a senior scientist. Working his way though the ranks, Levinson became Vice President of Research Technology in 1989 and was named President and CEO in 1995. Interviewed at the sprawling corporate headquarters in South San Francisco, Levinson reflected on the process of high risk science, the benefits of the private sector, and the changing relationship between biotech companies and the academic world.

  17. Identifying bubble collapse in a hydrothermal system using hidden Markov models

    2012-01-01

    Beginning in July 2003 and lasting through September 2003, the Norris Geyser Basin in Yellowstone National Park exhibited an unusual increase in ground temperature and hydrothermal activity. Using hidden Markov model theory, we identify over five million high-frequency (>15Hz) seismic events observed at a temporary seismic station deployed in the basin in response to the increase in hydrothermal activity. The source of these seismic events is constrained to within ???100 m of the station, and produced ???3500-5500 events per hour with mean durations of ???0.35-0.45s. The seismic event rate, air temperature, hydrologic temperatures, and surficial water flow of the geyser basin exhibited a marked diurnal pattern that was closely associated with solar thermal radiance. We interpret the source of the seismicity to be due to the collapse of small steam bubbles in the hydrothermal system, with the rate of collapse being controlled by surficial temperatures and daytime evaporation rates. copyright 2012 by the American Geophysical Union.

  18. Conclusions about properties of high-energy cosmic-rays drawn with limited recourse to hadronic models

    2016-01-01

    Determining the energy and mass of the highest energy cosmic rays requires knowledge of features of particle interactions at energies beyond those reached at the LHC. Inadequacies of the model predictions set against a variety of data are summarised and it is clear that firm statements about primary mass are premature. Nonetheless, conclusions of significance about the origin of the highest-energy cosmic rays can be deduced from the data. This paper is dedicated to my great friend and colleague, Jim Cronin, who died suddenly on 25 August 2016, without whom the Auger Collaboration would not have happened.

    2013-01-01

    Modeling of technical machines became a standard technique since computer became powerful enough to handle the amount of data relevant to the specific system. Simulation of an existing physical device requires the knowledge of all relevant quantities. Electric fields given by the surrounding boundary as well as magnetic fields caused by coils or permanent magnets have to be known. Internal sources for both fields are sometimes taken into account, such as space charge forces or the internal magnetic field of a moving bunch of charged particles. Used solver routines are briefly described and some bench-marking is shown to estimate necessary computing times for different problems. Different types of charged particle sources will be shown together with a suitable model to describe the physical model. Electron guns are covered as well as different ion sources (volume ion sources, laser ion sources, Penning ion sources, electron resonance ion sources, and H$^-$-sources) together with some remarks on beam transport.

  2. AC transport current loss in a coated superconductor in the Bean model

    2004-10-15

    A new and straightforward calculation is made of the loss in a very thin superconducting strip of rectangular cross-section (e.g. the coating on a coated superconductor) carrying ac transport current in zero applied magnetic field, with a similar strip acting as the return path. The computation is made assuming only that the strip is composed of uniform material which obeys Maxwell's equations and the Bean model. An important consequence of the Bean model is the existence of a field-free region about the middle of the superconductor cross-section. The present loss calculation is novel in two respects: (1) It uses for the first time an actual computation of the shape of the field-free region rather than using qualitative assumptions, and (2) it uses a new approach for making the loss calculation, based on a rigorous solution of Maxwell's equations for this problem. The rigorous solution correctly treats the problem as three-dimensional, having a time-dependent charge on the surface of the superconductor, and having the electric field described by both a vector and a scalar potential. Loss computations are made for the ratio of peak current to critical current in the approximate range of one-half to one, where within this range the loss decreases by about two powers of 10. The most important result coming out of the present calculation (made for the case of a distant return path large compared with the conductor cross-section dimensions but small compared with the length of the conductor), is a confirmation of Norris's previously estimated loss expression which he obtained in a different way.

    Although all chemists know the importance of chemistry in daily life, the rest of the population somehow does not seem to share this view. Each of us believes that we must teach chemistry to everyone, yet we have not succeeded in persuading everyone that they must study chemistry. The reason is often the methods used to communicate chemistry to the public. The arts (music, dance, drama, fine arts, etc.) are excellent vehicles to enhance understanding. For eample, most people are not interested in the concept of the ionic bond, but when presented like Shakespeare's Romeo and Juliet (with a love story between Sodium and Chlorine) everyone enjoys learning about the bonding relationship. In addition, the drama students who write and act out the script remember the concept far longer than would be expected through more conventional teaching methods. The same is true for the students who wrote and acted The Bondfather, and for the students who danced The Three States of Matter. (Our hero falls in love with Solid, but "When she warms to him, through his fingers she runs," and when his love heats up with Liquid, "Her love escaped from him just like a vapor.")

    2002-07-01

    This is the seventh Quarterly Technical Report for DOE Cooperative Agreement No. DE-FC26-00NT40895. A statement of the project objectives is included in the Introduction of this report. Two additional biomass co-firing test burns were conducted during this quarter. In the first test (Test 12), up to 20% by weight dry hardwood sawdust and switchgrass was comilled with Galatia coal and injected through the single-register burner. Liquid ammonia was intermittently added to the primary air stream to increase fuel-bound nitrogen and simulate cofiring with chicken litter. Galatia coal is a medium-sulfur ({approx} 1.2% S), high chlorine ({approx}0.5%) Illinois Basin coal. In the second test (Test 13), up to 20% by weight dry hardwood sawdust and switchgrass was comilled with Jim Walters No.7 mine coal and injected through the single-register burner. Jim Walters No.7 coal is a low-volatility, low-sulfur ({approx} 0.7% S) Eastern bituminous coal. The results of these tests are presented in this quarterly report. Progress has continued to be made in implementing a modeling approach to combine reaction times and temperature distributions from computational fluid dynamic models of the pilot-scale combustion furnace with char burnout and chemical reaction kinetics to predict NO{sub x} emissions and unburned carbon levels in the furnace exhaust. The Configurable Fireside Simulator has been delivered from REI, Inc. and is being tested with exiting CFD solutions. Preparations are under way for a final pilot-scale combustion experiment using the single-register burner fired with comilled mixtures of Jim Walters No.7 low-volatility bituminous coal and switchgrass. Because of the delayed delivery of the Configurable Fireside Simulator, it is planned to ask for a no-cost time extension for the project until the end of this calendar year. Finally, a paper describing this project that included preliminary results from the first four cofiring tests was presented at the 12th European

    2012-01-01

    Near-infrared reflectance photoacoustic spectroscopy (NIRS) was applied to fast determination of soil organic matter (SOM) by different quantitative methods. The dried samples of five different soil types in the middle and eastern China were selected to assess the quantitative estimation of SOM based on different modeling methods. First derivative, multiplicative scatter correction (MSC) and smoothing algorithms were used to preprocess the original spectra before the calibration models were developed. The results showed that different pre-processing algorithms markedly affected the accuracy of SOM calibration models. The sequence of SOM models with different pre-processing algorithms was MSC+ Norris-gap first derivative smoothing filter (NGFD) > MSC >Norris first derivative smoothing filter > standard normal variate (SNV) > Norris-gap second derivative smoothing filter (NGSD) > LOG > Savitzky-Golay first derivative (SGFD) > Savitzky-Golay second derivative (SGSD). The spectra processed with the combination of MSC and NGFD performed the best among all the pre-processing algorithms. In addition, the calibration model based on PLS-BPNN displayed the highest estimation accuracy with R2 of 0.97 and RMSEP of 1.88, followed by PLS, SMLR and PCR, while the validation model with independent data gave R2 of 0.97 and RMSEP of 1.72, respectively. These results indicated that PLS-BPNN based on MSC-NGFD spectra was a potentially optimal method for SOM estimation.%该研究的目的在于应用近红外光声光谱技术结合不同的定量分析方法实现5种不同类型土壤有机质含量的快速估测.对中国中、东部地区5种不同类型土壤风干样本进行光谱扫描,经过多元散射校正、一阶导数、二阶导数及平滑等预处理后,应用逐步多元回归(SMLR)、主成分分析(PCR)、偏最小二乘法(PLS)和偏最小二乘法-反向传播神经网络(PLS-BPNN)等方法建立土壤有机质含量的定量估测模型.结果显示,不同预

    Full Text Available Although film history has mostly been understood in national terms, there have also been attempts to present a general history of film styles. The history of film styles can be roughly divided into four distinct phases, each drawing on different aspects of narration. In the beginning, cinema privileged documentation and spectacle, presenting the exhibitionistic aspect of the new medium, whose structural characteristics had yet to be explored. Nöel Burch labeled this pre-narrative style a Primitive Mode of Representation, and this mode defied the narrative aspect of film-making. The shift towards narration occurred in the period between 1907 and 1909, when narrative films became the dominant mode of storytelling. The transition towards narrative cinema was mainly prompted by the demands of the market, which resulted in the gradual predominance of fictional narratives. The new style became known as the classical realist cinema, and Classical Hollywood Cinema became the leading representative.

    2012-03-01

    Full Text Available The Limits of Control is considered an American film, although it relies on funding coming from foreign countries and on a multinational cast. The analysis of American reviews shows a rejection of the movie that is seen as un-American; American critics fail to focus on the film maker’s original depiction of Spain. Conversely, Spanish critics warmly welcome Jarmusch’s film. Their interest centers on the new vision of Spain it offers, and on the ideological criticism expressed by the various characters. Such a national approval paradoxically stems from a filmic text where nationality is voluntarily deconstructed through themes that are cut off from any references to nationality, and from a general defiance towards language, which undermines the role of national idioms in the building of national identity.

  5. Structural Organization of Insulin Fibrils Based on Polarized Raman Spectroscopy: Evaluation of Existing Models.

    Science.gov (United States)

    Sereda, Valentin; Sawaya, Michael R; Lednev, Igor K

    2015-09-01

    Many different proteins undergo misfolding and self-assemble into amyloid fibrils, resulting in a range of neurodegenerative diseases. The limitations of conventional methods of structural biology for fibril characterization have led to the use of polarized Raman spectroscopy for obtaining quantitative structural information regarding the organization of amyloid fibrils. Herein, we report the orientation of selected chemical groups and secondary structure elements in aligned insulin fibrils, including β-sheets, which possess a high level of orientation in the cross-β core, and α-helices in the disordered portions of the fibrils. Strong orientation of disulfide bonds in amyloid fibrils was also revealed, indicating their association with the fibril core. The determined orientation of chemical groups provides strong constraints for modeling the overall structure of amyloid fibrils, including the core and disordered parts. The developed methodology allows for the validation of structural models proposed in the literature for amyloid fibrils. Specifically, the polarized Raman data obtained herein strongly agreed with two insulin fibril models (Jiménez et al., Proc. Natl. Acad. Sci. U. S. A. 2002, 99, 9196-9201 and Ivanova et al., Proc. Natl. Acad. Sci. U. S. A. 2009, 106, 18990-18995) yet revealed significant qualitative and quantitative differences. This work demonstrates the great potential of polarized Raman spectroscopy for structural characterization of anisotropic biological species.

    2016-09-01

    Idaho National Laboratory is currently evolving the modeling and simulation (M&S) capability that will enable improved core operation as well as design and analysis of TREAT experiments. This M&S capability primarily uses MAMMOTH, a reactor physics application being developed under the Multi-physics Object Oriented Simulation Environment (MOOSE) framework. MAMMOTH allows the coupling of a number of other MOOSE-based applications. In support of this research, INL is working with four universities to explore advanced solution methods that will complement or augment capabilities in MAMMOTH. This report consists of a collection of year end summaries of research from the universities performed in support of TREAT modeling and simulation. This research was led by Prof. Sedat Goluoglu at the University of Florida, Profs. Jim Morel and Jean Ragusa at Texas A&M University, Profs. Benoit Forget and Kord Smith at Massachusetts Institute of Technology, Prof. Leslie Kerby of Idaho State University and Prof. Barry Ganapol of University of Arizona. A significant number of students were supported at various levels though the projects and, for some, also as interns at INL.

Early researchers looked to the globin genes as an excellent model in which to examine gene regulation – bountifully expressed and displaying a remarkably consistent pattern of developmental activation and silencing. In parallel with the growth of research into expression of the globin genes, mutations within the β-globin gene were identified as the cause of the β-hemoglobinopathies such as sickle cell disease and β-thalassemia. These lines of enquiry stimulated the development of transgenic mouse models, first carrying individual human globin genes and then substantial human genomic fragments incorporating the multigenic human β-globin locus and regulatory elements. Finally, mice were devised carrying mutant human β-globin loci on genetic backgrounds deficient in the native mouse globins, resulting in phenotypes of sickle cell disease or β-thalassemia. These years of work have generated a group of model animals that display many features of the β-hemoglobinopathies and provided enormous insight into the mechanisms of gene regulation. Substantive differences in the expression of human and mouse globins during development have also come to light, revealing the limitations of the mouse model, but also providing opportunities to further explore the mechanisms of globin gene regulation. In addition, animal models of β-hemoglobinopathies have demonstrated the feasibility of gene therapy for these conditions, now showing success in human clinical trials. Such models remain in use to dissect the molecular events of globin gene regulation and to identify novel treatments based

    Directory of Open Access Journals (Sweden)

    Michael Piefel

    2007-02-01

    Full Text Available Today's software systems are too complex to implement them and model them using only one language. As a result, modern software engineering uses different languages for different levels of abstraction and different system aspects. Thus to handle an increasing number of related or integrated languages is the most challenging task in the development of tools. We use object oriented metamodelling to describe languages. Object orientation allows us to derive abstract reusable concept definitions (concept classes from existing languages. This language definition technique concentrates on semantic abstractions rather than syntactical peculiarities. We present a set of common concept classes that describe structure, behaviour, and data aspects of high-level modelling languages. Our models contain syntax modelling using the OMG MOF as well as static semantic constraints written in OMG OCL. We derive metamodels for subsets of SDL and UML from these common concepts, and we show for parts of these languages that they can be modelled and related to each other through the same abstract concepts.

  8. Promoting Models

    Science.gov (United States)

    Li, Qin; Zhao, Yongxin; Wu, Xiaofeng; Liu, Si

    There can be multitudinous models specifying aspects of the same system. Each model has a bias towards one aspect. These models often override in specific aspects though they have different expressions. A specification written in one model can be refined by introducing additional information from other models. The paper proposes a concept of promoting models which is a methodology to obtain refinements with support from cooperating models. It refines a primary model by integrating the information from a secondary model. The promotion principle is not merely an academic point, but also a reliable and robust engineering technique which can be used to develop software and hardware systems. It can also check the consistency between two specifications from different models. A case of modeling a simple online shopping system with the cooperation of the guarded design model and CSP model illustrates the practicability of the promotion principle.

    Concrete is perhaps one of the most widely used construction materials in the world. Engineers use it to build massive concrete dams, concrete waterways, highways, bridges, and even nuclear reactors. The advantages of using concrete is that it can be cast into any desired shape, it is durable, and very economical compared to structural steel. The disadvantages are its low tensile strength, low ductility, and low strength-to-weight ratio. Concrete is a composite material that consists of a coarse granular material, or aggregate, embedded in a hard matrix of material, or cement, which fills the gaps between the aggregates and binds them together. Concrete properties, however, vary widely. The properties depend on the choice of materials used and the proportions for a particular application, as well as differences in fabrication techniques. Table 1 provides a listing of typical engineering properties for structural concrete. Properties also depend on the level of concrete confinement, or hydrostatic pressure, the material is being subjected to. In general, concrete is rarely subjected to a single axial stress. The material may experience a combination of stresses all acting simultaneously. The behavior of concrete under these combined stresses are, however, extremely difficult to characterize. In addition to the type of loading, one must also consider the stress history of the material. Failure is determined not only by the ultimate stresses, but also by the rate of loading and the order in which these stresses were applied. The concrete model described herein accounts for this complex behavior of concrete. It was developed by Javier Malvar, Jim Wesevich, and John Crawford of Karagozian and Case, and Don Simon of Logicon RDA in support of the Defense Threat Reduction Agency's programs. The model is an enhanced version of the Concrete/Geological Material Model 16 in the Lagrangian finite element code DYNA3D. The modifications that were made to the original model

    AIM: To examine the effectiveness of human placental inhibitors, by injecting vitamin E to rats with transplanted Norris-5123 hepatoma, on the expression of cathepsins B and L in tumor, liver, lung and blood sera after transplantation of Norris 5123 hepatoma.METHODS: Animals were divided into 10 groups receiving three different concentrations of vitamin E and inhibitors along or in combination and compared with negative control (healthy rats) and positive control (tumor rats). Effectiveness of treatment was evaluated with regard to survival time,tumor response and determination of the activities of proteolytic enzymes and their inhibitors using flurogenic substrates.RESULTS: Cathepsins B and L activities were elevated by 16-fold in comparison with negative control tissues, and their endogenous inhibitor activity decreased by 1.2-fold before treatment. In several cases, tumors completely disappeared following vitamin E plus human placental cyteine protease inhibitor (CPI) compared with controls.The number of complete tumor responses was higher when 20 m/kg vitamin E plus 400 μg of CPI was used, i.e.7/10 rats survived more than two mo. Cathepsins B and L were expressed significantly in tumor, liver, lung tissues and sera in parallel to the increasing of the endogenous inhibitor activity compared with the controls after treatment (P<0.0001).CONCLUSION: The data indicate formation of metastasis significantly reduced in treated rats, which might provide a therapeutic basis for anti-cancer therapy.

    The Second Workshop on Stratospheric Models and Measurements Workshop (M&M II) is the continuation of the effort previously started in the first Workshop (M&M I, Prather and Remsberg [1993]) held in 1992. As originally stated, the aim of M&M is to provide a foundation for establishing the credibility of stratospheric models used in environmental assessments of the ozone response to chlorofluorocarbons, aircraft emissions, and other climate-chemistry interactions. To accomplish this, a set of measurements of the present day atmosphere was selected. The intent was that successful simulations of the set of measurements should become the prerequisite for the acceptance of these models as having a reliable prediction for future ozone behavior. This section is divided into two: model experiment and model descriptions. In the model experiment, participant were given the charge to design a number of experiments that would use observations to test whether models are using the correct mechanisms to simulate the distributions of ozone and other trace gases in the atmosphere. The purpose is closely tied to the needs to reduce the uncertainties in the model predicted responses of stratospheric ozone to perturbations. The specifications for the experiments were sent out to the modeling community in June 1997. Twenty eight modeling groups responded to the requests for input. The first part of this section discusses the different modeling group, along with the experiments performed. Part two of this section, gives brief descriptions of each model as provided by the individual modeling groups.

The code is based on physical relationships that describe the shared variability of meteorological parameters such as temperature, humidity, precipitation rate, circulation, radiation fluxes, etc. Three-dimensional climate models are integrated over time in order to compute the temporal and spatial variations of these parameters. Model domains can be global or regional and the horizontal and vertical resolutions of the computational grid vary from model to model. Considering the entire climate system requires accounting for interactions between solar insolation, atmospheric, oceanic and continental processes, the latter including land hydrology and vegetation. Model simulations may concentrate on one or more of these components, but the most sophisticated models will estimate the mutual interactions of all of these environments. Advances in computer technology have prompted investments in more complex model configurations that consider more phenomena interactions than were possible with yesterday s computers. However, not every attempt to add to the computational layers is rewarded by better model performance. Extensive research is required to test and document any advantages gained by greater sophistication in model formulation. One purpose for publishing climate model research results is to present purported advances for evaluation by the scientific community.

    CERN Document Server

    2016-01-01

    This book provides a thorough introduction to the challenge of applying mathematics in real-world scenarios. Modelling tasks rarely involve well-defined categories, and they often require multidisciplinary input from mathematics, physics, computer sciences, or engineering. In keeping with this spirit of modelling, the book includes a wealth of cross-references between the chapters and frequently points to the real-world context. The book combines classical approaches to modelling with novel areas such as soft computing methods, inverse problems, and model uncertainty. Attention is also paid to the interaction between models, data and the use of mathematical software. The reader will find a broad selection of theoretical tools for practicing industrial mathematics, including the analysis of continuum models, probabilistic and discrete phenomena, and asymptotic and sensitivity analysis.

    2011-01-01

    In this report a new turbulence model is presented.In contrast to the bulk of modern work, the model is a classical continuum model with a relatively simple constitutive equation. The constitutive equation is, as usual in continuum mechanics, entirely empirical. It has the usual Newton or Stokes...... term with stresses depending linearly on the strain rates. This term takes into account the transfer of linear momentum from one part of the fluid to another. Besides there is another term, which takes into account the transfer of angular momentum. Thus the model implies a new definition of turbulence....... The model is in a virgin state, but a number of numerical tests have been carried out with good results. It is published to encourage other researchers to study the model in order to find its merits and possible limitations....

    2002-10-05

    The purpose of the Ventilation Model is to simulate the heat transfer processes in and around waste emplacement drifts during periods of forced ventilation. The model evaluates the effects of emplacement drift ventilation on the thermal conditions in the emplacement drifts and surrounding rock mass, and calculates the heat removal by ventilation as a measure of the viability of ventilation to delay the onset of peak repository temperature and reduce its magnitude. The heat removal by ventilation is temporally and spatially dependent, and is expressed as the fraction of heat carried away by the ventilation air compared to the fraction of heat produced by radionuclide decay. One minus the heat removal is called the wall heat fraction, or the remaining amount of heat that is transferred via conduction to the surrounding rock mass. Downstream models, such as the ''Multiscale Thermohydrologic Model'' (BSC 2001), use the wall heat fractions as outputted from the Ventilation Model to initialize their post-closure analyses. The Ventilation Model report was initially developed to analyze the effects of preclosure continuous ventilation in the Engineered Barrier System (EBS) emplacement drifts, and to provide heat removal data to support EBS design. Revision 00 of the Ventilation Model included documentation of the modeling results from the ANSYS-based heat transfer model. The purposes of Revision 01 of the Ventilation Model are: (1) To validate the conceptual model for preclosure ventilation of emplacement drifts and verify its numerical application in accordance with new procedural requirements as outlined in AP-SIII-10Q, Models (Section 7.0). (2) To satisfy technical issues posed in KTI agreement RDTME 3.14 (Reamer and Williams 2001a). Specifically to demonstrate, with respect to the ANSYS ventilation model, the adequacy of the discretization (Section 6.2.3.1), and the downstream applicability of the model results (i.e. wall heat fractions) to

    Full Text Available Currently deep learning has made great breakthroughs in visual and speech processing, mainly because it draws lessons from the hierarchical mode that brain deals with images and speech. In the field of NLP, a topic model is one of the important ways for modeling documents. Topic models are built on a generative model that clearly does not match the way humans write. In this paper, we propose Event Model, which is unsupervised and based on the language processing mechanism of neurolinguistics, to model documents. In Event Model, documents are descriptions of concrete or abstract events seen, heard, or sensed by people and words are objects in the events. Event Model has two stages: word learning and dimensionality reduction. Word learning is to learn semantics of words based on deep learning. Dimensionality reduction is the process that representing a document as a low dimensional vector by a linear mode that is completely different from topic models. Event Model achieves state-of-the-art results on document retrieval tasks.

    Hoeting, Jennifer A.; Davis, Richard A.; Merton, Andrew A.; Thompson, Sandra E.

    2006-02-01

    We consider the problem of model selection for geospatial data. Spatial correlation is typically ignored in the selection of explanatory variables and this can influence model selection results. For example, the inclusion or exclusion of particular explanatory variables may not be apparent when spatial correlation is ignored. To address this problem, we consider the Akaike Information Criterion (AIC) as applied to a geostatistical model. We offer a heuristic derivation of the AIC in this context and provide simulation results that show that using AIC for a geostatistical model is superior to the often used approach of ignoring spatial correlation in the selection of explanatory variables. These ideas are further demonstrated via a model for lizard abundance. We also employ the principle of minimum description length (MDL) to variable selection for the geostatistical model. The effect of sampling design on the selection of explanatory covariates is also explored.

  9. Linguistic models and linguistic modeling.

    Pedryez, W; Vasilakos, A V

    1999-01-01

    The study is concerned with a linguistic approach to the design of a new category of fuzzy (granular) models. In contrast to numerically driven identification techniques, we concentrate on budding meaningful linguistic labels (granules) in the space of experimental data and forming the ensuing model as a web of associations between such granules. As such models are designed at the level of information granules and generate results in the same granular rather than pure numeric format, we refer to them as linguistic models. Furthermore, as there are no detailed numeric estimation procedures involved in the construction of the linguistic models carried out in this way, their design mode can be viewed as that of a rapid prototyping. The underlying algorithm used in the development of the models utilizes an augmented version of the clustering technique (context-based clustering) that is centered around a notion of linguistic contexts-a collection of fuzzy sets or fuzzy relations defined in the data space (more precisely a space of input variables). The detailed design algorithm is provided and contrasted with the standard modeling approaches commonly encountered in the literature. The usefulness of the linguistic mode of system modeling is discussed and illustrated with the aid of numeric studies including both synthetic data as well as some time series dealing with modeling traffic intensity over a broadband telecommunication network.

    2013-01-01

    The absence of industrial scale nuclear fuel reprocessing in the U.S. has precluded the necessary driver for developing the advanced simulation capability now prevalent in so many other countries. Thus, it is essential to model complex series of unit operations to simulate, understand, and predict inherent transient behavior and feedback loops. A capability of accurately simulating the dynamic behavior of advanced fuel cycle separation processes will provide substantial cost savings and many technical benefits. The specific fuel cycle separation process discussed in this report is the off-gas treatment system. The off-gas separation consists of a series of scrubbers and adsorption beds to capture constituents of interest. Dynamic models are being developed to simulate each unit operation involved so each unit operation can be used as a stand-alone model and in series with multiple others. Currently, an adsorption model has been developed within Multi-physics Object Oriented Simulation Environment (MOOSE) developed at the Idaho National Laboratory (INL). Off-gas Separation and REcoverY (OSPREY) models the adsorption of off-gas constituents for dispersed plug flow in a packed bed under non-isothermal and non-isobaric conditions. Inputs to the model include gas, sorbent, and column properties, equilibrium and kinetic data, and inlet conditions. The simulation outputs component concentrations along the column length as a function of time from which breakthrough data is obtained. The breakthrough data can be used to determine bed capacity, which in turn can be used to size columns. It also outputs temperature along the column length as a function of time and pressure drop along the column length. Experimental data and parameters were input into the adsorption model to develop models specific for krypton adsorption. The same can be done for iodine, xenon, and tritium. The model will be validated with experimental breakthrough curves. Customers will be given access to

  11. Model hydrographs

    1972-01-01

    Model hydrographs are composed of pairs of dimensionless ratios, arrayed in tabular form, which, when modified by the appropriate values of rainfall exceed and by the time and areal characteristics of the drainage basin, satisfactorily represent the flood hydrograph for the basin. Model bydrographs are developed from a dimensionless translation hydrograph, having a time base of T hours and appropriately modified for storm duration by routing through reservoir storage, S=kOx. Models fall into two distinct classes: (1) those for which the value of x is unity and which have all the characteristics of true unit hydrographs and (2) those for which the value of x is other than unity and to which the unit-hydrograph principles of proportionality and superposition do not apply. Twenty-six families of linear models and eight families of nonlinear models in tabular form from the principal subject of this report. Supplemental discussions describe the development of the models and illustrate their application. Other sections of the report, supplemental to the tables, describe methods of determining the hydrograph characteristics, T, k, and x, both from observed hydrograph and from the physical characteristics of the drainage basin. Five illustrative examples of use show that the models, when properly converted to incorporate actual rainfall excess and the time and areal characteristics of the drainage basins, do indeed satisfactorily represent the observed flood hydrographs for the basins.

    2017-03-01

    Structural characterization of proteins is essential for understanding life processes at the molecular level. However, only a fraction of known proteins have experimentally determined structures. This fraction is even smaller for protein-protein complexes. Thus, structural modeling of protein-protein interactions (docking) primarily has to rely on modeled structures of the individual proteins, which typically are less accurate than the experimentally determined ones. Such "double" modeling is the Grand Challenge of structural reconstruction of the interactome. Yet it remains so far largely untested in a systematic way. We present a comprehensive validation of template-based and free docking on a set of 165 complexes, where each protein model has six levels of structural accuracy, from 1 to 6 Å C(α) RMSD. Many template-based docking predictions fall into acceptable quality category, according to the CAPRI criteria, even for highly inaccurate proteins (5-6 Å RMSD), although the number of such models (and, consequently, the docking success rate) drops significantly for models with RMSD > 4 Å. The results show that the existing docking methodologies can be successfully applied to protein models with a broad range of structural accuracy, and the template-based docking is much less sensitive to inaccuracies of protein models than the free docking.

    Although vacuum arcs were first identified over 110 years ago, they are not yet well understood. We have since developed a model of breakdown and gradient limits that tries to explain, in a self-consistent way: arc triggering, plasma initiation, plasma evolution, surface damage and gra- dient limits. We use simple PIC codes for modeling plasmas, molecular dynamics for modeling surface breakdown, and surface damage, and mesoscale surface thermodynamics and finite element electrostatic codes for to evaluate surface properties. Since any given experiment seems to have more variables than data points, we have tried to consider a wide variety of arcing (rf structures, e beam welding, laser ablation, etc.) to help constrain the problem, and concentrate on common mechanisms. While the mechanisms can be comparatively simple, modeling can be challenging.

    Regardt, Olle; Rönnbäck, Lars; Bergholtz, Maria; Johannesson, Paul; Wohed, Petia

    Maintaining and evolving data warehouses is a complex, error prone, and time consuming activity. The main reason for this state of affairs is that the environment of a data warehouse is in constant change, while the warehouse itself needs to provide a stable and consistent interface to information spanning extended periods of time. In this paper, we propose a modeling technique for data warehousing, called anchor modeling, that offers non-destructive extensibility mechanisms, thereby enabling robust and flexible management of changes in source systems. A key benefit of anchor modeling is that changes in a data warehouse environment only require extensions, not modifications, to the data warehouse. This ensures that existing data warehouse applications will remain unaffected by the evolution of the data warehouse, i.e. existing views and functions will not have to be modified as a result of changes in the warehouse model.

  3. Do stroke models model stroke?

    Directory of Open Access Journals (Sweden)

    Philipp Mergenthaler

    2012-11-01

    Full Text Available Stroke is one of the leading causes of death worldwide and the biggest reason for long-term disability. Basic research has formed the modern understanding of stroke pathophysiology, and has revealed important molecular, cellular and systemic mechanisms. However, despite decades of research, most translational stroke trials that aim to introduce basic research findings into clinical treatment strategies – most notably in the field of neuroprotection – have failed. Among other obstacles, poor methodological and statistical standards, negative publication bias, and incomplete preclinical testing have been proposed as ‘translational roadblocks’. In this article, we introduce the models commonly used in preclinical stroke research, discuss some of the causes of failed translational success and review potential remedies. We further introduce the concept of modeling ‘care’ of stroke patients, because current preclinical research models the disorder but does not model care or state-of-the-art clinical testing. Stringent statistical methods and controlled preclinical trials have been suggested to counteract weaknesses in preclinical research. We conclude that preclinical stroke research requires (1 appropriate modeling of the disorder, (2 appropriate modeling of the care of stroke patients and (3 an approach to preclinical testing that is similar to clinical testing, including Phase 3 randomized controlled preclinical trials as necessary additional steps before new therapies enter clinical testing.

    Mathematical models are the decisive tool to explain and predict phenomena in the natural and engineering sciences. With this book readers will learn to derive mathematical models which help to understand real world phenomena. At the same time a wealth of important examples for the abstract concepts treated in the curriculum of mathematics degrees are given. An essential feature of this book is that mathematical structures are used as an ordering principle and not the fields of application. Methods from linear algebra, analysis and the theory of ordinary and partial differential equations are thoroughly introduced and applied in the modeling process. Examples of applications in the fields electrical networks, chemical reaction dynamics, population dynamics, fluid dynamics, elasticity theory and crystal growth are treated comprehensively.

    2006-01-01

    A physically-based model is presented for the simulation of a new type of deformable objects-inflatable objects, such as shaped balloons, which consist of pressurized air enclosed by an elastic surface. These objects have properties inherent in both 3D and 2D elastic bodies, as they demonstrate the behaviour of 3D shapes using 2D formulations. As there is no internal structure in them, their behaviour is substantially different from the behaviour of deformable solid objects. We use one of the few available models for deformable surfaces, and enhance it to include the forces of internal and external pressure. These pressure forces may also incorporate buoyancy forces, to allow objects filled with a low density gas to float in denser media. The obtained models demonstrate rich dynamic behaviour, such as bouncing, floating, deflation and inflation.

  10. Smashnova Model

    2007-01-01

    An alternate model for gamma ray bursts is suggested. For a white dwarf (WD) and neutron star (NS) very close binary system, the WD (close to Mch) can detonate due to tidal heating, leading to a SN. Material falling on to the NS at relativistic velocities can cause its collapse to a magnetar or quark star or black hole leading to a GRB. As the material smashes on to the NS, it is dubbed the Smashnova model. Here the SN is followed by a GRB. NS impacting a RG (or RSG) (like in Thorne-Zytkow objects) can also cause a SN outburst followed by a GRB. Other variations are explored.

    Full Text Available Next generation sequencing technologies are bringing about a renaissance of mining approaches. A comprehensive picture of the genetic landscape of an individual patient will be useful, for example, to identify groups of patients that do or do not respond to certain therapies. The high expectations may however not be satisfied if the number of patient groups with similar characteristics is going to be very large. I therefore doubt that mining sequence data will give us an understanding of why and when therapies work. For understanding the mechanisms underlying diseases, an alternative approach is to model small networks in quantitative mechanistic detail, to elucidate the role of gene and proteins in dynamically changing the functioning of cells. Here an obvious critique is that these models consider too few components, compared to what might be relevant for any particular cell function. I show here that mining approaches and dynamical systems theory are two ends of a spectrum of methodologies to choose from. Drawing upon personal experience in numerous interdisciplinary collaborations, I provide guidance on how to model by discussing the question Why model?

    The emergence of interactive art has blurred the line between electronic, computer graphics and art. Here we apply this art form to numerical models. Here we show how the transformation of a numerical model into an interactive painting can both provide insights and solve real world problems. The cases that are used as an example include forensic reconstructions, dredging optimization, barrier design. The system can be fed using any source of time varying vector fields, such as hydrodynamic models. The cases used here, the Indian Ocean (HYCOM), the Wadden Sea (Delft3D Curvilinear), San Francisco Bay (3Di subgrid and Delft3D Flexible Mesh), show that the method used is suitable for different time and spatial scales. High resolution numerical models become interactive paintings by exchanging their velocity fields with a high resolution (>=1M cells) image based flow visualization that runs in a html5 compatible web browser. The image based flow visualization combines three images into a new image: the current image, a drawing, and a uv + mask field. The advection scheme that computes the resultant image is executed in the graphics card using WebGL, allowing for 1M grid cells at 60Hz performance on mediocre graphic cards. The software is provided as open source software. By using different sources for a drawing one can gain insight into several aspects of the velocity fields. These aspects include not only the commonly represented magnitude and direction, but also divergence, topology and turbulence .

    The ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2003) presents the methodology for evaluating potential criticality situations in the monitored geologic repository. As stated in the referenced Topical Report, the detailed methodology for performing the disposal criticality analyses will be documented in model reports. Many of the models developed in support of the Topical Report differ from the definition of models as given in the Office of Civilian Radioactive Waste Management procedure AP-SIII.10Q, ''Models'', in that they are procedural, rather than mathematical. These model reports document the detailed methodology necessary to implement the approach presented in the Disposal Criticality Analysis Methodology Topical Report and provide calculations utilizing the methodology. Thus, the governing procedure for this type of report is AP-3.12Q, ''Design Calculations and Analyses''. The ''Criticality Model'' is of this latter type, providing a process evaluating the criticality potential of in-package and external configurations. The purpose of this analysis is to layout the process for calculating the criticality potential for various in-package and external configurations and to calculate lower-bound tolerance limit (LBTL) values and determine range of applicability (ROA) parameters. The LBTL calculations and the ROA determinations are performed using selected benchmark experiments that are applicable to various waste forms and various in-package and external configurations. The waste forms considered in this calculation are pressurized water reactor (PWR), boiling water reactor (BWR), Fast Flux Test Facility (FFTF), Training Research Isotope General Atomic (TRIGA), Enrico Fermi, Shippingport pressurized water reactor, Shippingport light water breeder reactor (LWBR), N-Reactor, Melt and Dilute, and Fort Saint Vrain Reactor spent nuclear fuel (SNF).

    Generating extreme weather event sets from very large ensembles of regional climate models Neil Massey, Benoit P. Guillod, Friederike E. L. Otto, Myles R. Allen, Richard Jones, Jim W. Hall Environmental Change Institute, University of Oxford, Oxford, UK Extreme events can have large impacts on societies and are therefore being increasingly studied. In particular, climate change is expected to impact the frequency and intensity of these events. However, a major limitation when investigating extreme weather events is that, by definition, only few events are present in observations. A way to overcome this issue it to use large ensembles of model simulations. Using the volunteer distributed computing (VDC) infrastructure of weather@home [1], we run a very large number (10'000s) of RCM simulations over the European domain at a resolution of 25km, with an improved land-surface scheme, nested within a free-running GCM. Using VDC allows many thousands of climate model runs to be computed. Using observations for the GCM boundary forcings we can run historical "hindcast" simulations over the past 100 to 150 years. This allows us, due to the chaotic variability of the atmosphere, to ascertain how likely an extreme event was, given the boundary forcings, and to derive synthetic event sets. The events in these sets did not actually occur in the observed record but could have occurred given the boundary forcings, with an associated probability. The event sets contain time-series of fields of meteorological variables that allow impact modellers to assess the loss the event would incur. Projections of events into the future are achieved by modelling projections of the sea-surface temperature (SST) and sea-ice boundary forcings, by combining the variability of the SST in the observed record with a range of warming signals derived from the varying responses of SSTs in the CMIP5 ensemble to elevated greenhouse gas (GHG) emissions in three RCP scenarios.

    The article discusses the use of algorithmic models for so-called High Frequency Trading (HFT) in finance. HFT is controversial yet widespread in modern financial markets. It is a form of automated trading technology which critics among other things claim can lead to market manipulation. Drawing...... on two cases, this article shows that manipulation more likely happens in the reverse way, meaning that human traders attempt to make algorithms ‘make mistakes’ or ‘mislead’ algos. Thus, it is algorithmic models, not humans, that are manipulated. Such manipulation poses challenges for security exchanges....... The article analyses these challenges and argues that we witness a new post-social form of human-technology interaction that will lead to a reconfiguration of professional codes for financial trading....

    Acyclic models is a method heavily used to analyze and compare various homology and cohomology theories appearing in topology and algebra. This book is the first attempt to put together in a concise form this important technique and to include all the necessary background. It presents a brief introduction to category theory and homological algebra. The author then gives the background of the theory of differential modules and chain complexes over an abelian category to state the main acyclic models theorem, generalizing and systemizing the earlier material. This is then applied to various cohomology theories in algebra and topology. The volume could be used as a text for a course that combines homological algebra and algebraic topology. Required background includes a standard course in abstract algebra and some knowledge of topology. The volume contains many exercises. It is also suitable as a reference work for researchers.

  10. Nuclear Models

    2010-09-01

    The atomic nucleus is a typical example of a many-body problem. On the one hand, the number of nucleons (protons and neutrons) that constitute the nucleus is too large to allow for exact calculations. On the other hand, the number of constituent particles is too small for the individual nuclear excitation states to be explained by statistical methods. Another problem, particular for the atomic nucleus, is that the nucleon-nucleon (n-n) interaction is not one of the fundamental forces of Nature, and is hard to put in a single closed equation. The nucleon-nucleon interaction also behaves differently between two free nucleons (bare interaction) and between two nucleons in the nuclear medium (dressed interaction). Because of the above reasons, specific nuclear many-body models have been devised of which each one sheds light on some selected aspects of nuclear structure. Only combining the viewpoints of different models, a global insight of the atomic nucleus can be gained. In this chapter, we revise the the Nuclear Shell Model as an example of the microscopic approach, and the Collective Model as an example of the geometric approach. Finally, we study the statistical properties of nuclear spectra, basing on symmetry principles, to find out whether there is quantum chaos in the atomic nucleus. All three major approaches have been rewarded with the Nobel Prize of Physics. In the text, we will stress how each approach introduces its own series of approximations to reduce the prohibitingly large number of degrees of freedom of the full many-body problem to a smaller manageable number of effective degrees of freedom.

    Understanding the properties and behavior of biomembranes is fundamental to many biological processes and technologies. Microdomains in biomembranes or ''lipid rafts'' are now known to be an integral part of cell signaling, vesicle formation, fusion processes, protein trafficking, and viral and toxin infection processes. Understanding how microdomains form, how they depend on membrane constituents, and how they act not only has biological implications, but also will impact Sandia's effort in development of membranes that structurally adapt to their environment in a controlled manner. To provide such understanding, we created physically-based models of biomembranes. Molecular dynamics (MD) simulations and classical density functional theory (DFT) calculations using these models were applied to phenomena such as microdomain formation, membrane fusion, pattern formation, and protein insertion. Because lipid dynamics and self-organization in membranes occur on length and time scales beyond atomistic MD, we used coarse-grained models of double tail lipid molecules that spontaneously self-assemble into bilayers. DFT provided equilibrium information on membrane structure. Experimental work was performed to further help elucidate the fundamental membrane organization principles.

    In order to support enterprise integration, a kind of model construct based enterprise model architecture and its modeling approach are studied in this paper. First, the structural makeup and internal relationships of enterprise model architecture are discussed. Then, the concept of reusable model construct (MC) which belongs to the control view and can help to derive other views is proposed. The modeling approach based on model construct consists of three steps, reference model architecture synthesis, enterprise model customization, system design and implementation. According to MC based modeling approach a case study with the background of one-kind-product machinery manufacturing enterprises is illustrated. It is shown that proposal model construct based enterprise model architecture and modeling approach are practical and efficient.

Morgan recalls his early days in Ireland and New York City, education in parochial and public schools, and introduction to science in Cardinal Hayes High School, Bronx. In 1950, Jim entered Manhattan College, where he elected study of civil engineering, in particular water quality. Donald O'Connor motivated Jim's future study of O2 in rivers at Michigan, where in his MS work he learned to model O2 dynamics of rivers. As an engineering instructor at Illinois, Jim worked on rivers polluted by synthetic detergents. He chose to focus on chemical studies, seeing it as crucial for the environment. Jim enrolled for PhD studies with Werner Stumm at Harvard, who mentored his research in chemistry of particle coagulation and oxidation processes of Mn(II) and (IV). In succeeding decades, until retirement in 2000, Jim's teaching and research centered on aquatic chemistry; major themes comprised rates of abiotic manganese oxidation on particle surfaces and flocculation of natural water particles, and chemical speciation proved the key.

    Full Text Available Traditional wireless networks use the concept of the point-to-point forwarding inherited from reliable wired networks which seems to be not ideal for wireless environment. New emerging applications and networks operate mostly disconnected. So-called Delay-Tolerant networks (DTNs are receiving increasing attentions from both academia and industry. DTNs introduced a store-carry-and-forward concept solving the problem of intermittent connectivity. Behavior of such networks is verified by real models, computer simulation or combination of the both approaches. Computer simulation has become the primary and cost effective tool for evaluating the performance of the DTNs. OPNET modeler is our target simulation tool and we wanted to spread OPNET’s simulation opportunity towards DTN. We implemented bundle protocol to OPNET modeler allowing simulate cases based on bundle concept as epidemic forwarding which relies on flooding the network with messages and the forwarding algorithm based on the history of past encounters (PRoPHET.

    Full Text Available The current economic environment, together with the low scores obtained by our students in recent years, makes it necessary to incorporate new teaching methods. In this sense, econometric modelling provides a unique opportunity offering to the student with the basic tools to address the study of Econometrics in a deeper and novel way. In this article, this teaching method is described, presenting also an example based on a recent study carried out by two students of the Degree of Economics. Likewise, the success of this method is evaluated quantitatively in terms of academic performance. The results confirm our initial idea that the greater involvement of the student, as well as the need for a more complete knowledge of the subject, suppose a stimulus for the study of this subject. As evidence of this, we show how those students who opted for the method we propose here obtained higher qualifications than those that chose the traditional method.

    Full Text Available Enquanto muitos liberais acreditavam que educação e desenvolvimento econômico iriam corroer o preconceito racial, os líderes negros do movimento pelos direitos civis acreditavam - como os antigos Profetas Hebreus - que a tendência natural da sociedade era a corrupção. A inspiração profética ajudou os líderes negros a gerar solidariedade inédita e espírito de auto-sacrifício entre as massas negras do sul, cujo movimento assemelhou-se a um reavivamento religioso - com muito maior determinação que a demonstrada tanto por seus aliados liberais do norte, quanto por seus inimigos do sul.

  13. Better Language Models with Model Merging

    CERN Document Server

    Brants, T

    1996-01-01

    This paper investigates model merging, a technique for deriving Markov models from text or speech corpora. Models are derived by starting with a large and specific model and by successively combining states to build smaller and more general models. We present methods to reduce the time complexity of the algorithm and report on experiments on deriving language models for a speech recognition task. The experiments show the advantage of model merging over the standard bigram approach. The merged model assigns a lower perplexity to the test set and uses considerably fewer states.

  14. Model Selection Principles in Misspecified Models

    CERN Document Server

    Lv, Jinchi

    2010-01-01

    Model selection is of fundamental importance to high dimensional modeling featured in many contemporary applications. Classical principles of model selection include the Kullback-Leibler divergence principle and the Bayesian principle, which lead to the Akaike information criterion and Bayesian information criterion when models are correctly specified. Yet model misspecification is unavoidable when we have no knowledge of the true model or when we have the correct family of distributions but miss some true predictor. In this paper, we propose a family of semi-Bayesian principles for model selection in misspecified models, which combine the strengths of the two well-known principles. We derive asymptotic expansions of the semi-Bayesian principles in misspecified generalized linear models, which give the new semi-Bayesian information criteria (SIC). A specific form of SIC admits a natural decomposition into the negative maximum quasi-log-likelihood, a penalty on model dimensionality, and a penalty on model miss...

    Webb, Benjamin; Sali, Andrej

    2016-06-20

    Comparative protein structure modeling predicts the three-dimensional structure of a given protein sequence (target) based primarily on its alignment to one or more proteins of known structure (templates). The prediction process consists of fold assignment, target-template alignment, model building, and model evaluation. This unit describes how to calculate comparative models using the program MODELLER and how to use the ModBase database of such models, and discusses all four steps of comparative modeling, frequently observed errors, and some applications. Modeling lactate dehydrogenase from Trichomonas vaginalis (TvLDH) is described as an example. The download and installation of the MODELLER software is also described. © 2016 by John Wiley & Sons, Inc.

    2014-01-01

    A study of well-isolated pulses in gamma ray burst light curves indicates that simple models having smooth and monotonic pulse rises and decays are inadequate. Departures from the Norris et al. (2005) pulse shape are in the form of a wave-like pre-peak residual that is mirrored and stretched following the peak. Pulse shape departures are present in GRB pulses of all durations, but placement of the departures relative to pulse peaks correlates with asymmetry. This establishes an additional link between temporal structure and spectral evolution, as pulse asymmetry is related to initial hardness while pulse duration indicates the rate of hard-to-soft pulse evolution.

  17. Solicited abstract: Global hydrological modeling and models

    Science.gov (United States)

    Xu, Chong-Yu

    2010-05-01

    The origins of rainfall-runoff modeling in the broad sense can be found in the middle of the 19th century arising in response to three types of engineering problems: (1) urban sewer design, (2) land reclamation drainage systems design, and (3) reservoir spillway design. Since then numerous empirical, conceptual and physically-based models are developed including event based models using unit hydrograph concept, Nash's linear reservoir models, HBV model, TOPMODEL, SHE model, etc. From the late 1980s, the evolution of global and continental-scale hydrology has placed new demands on hydrologic modellers. The macro-scale hydrological (global and regional scale) models were developed on the basis of the following motivations (Arenll, 1999). First, for a variety of operational and planning purposes, water resource managers responsible for large regions need to estimate the spatial variability of resources over large areas, at a spatial resolution finer than can be provided by observed data alone. Second, hydrologists and water managers are interested in the effects of land-use and climate variability and change over a large geographic domain. Third, there is an increasing need of using hydrologic models as a base to estimate point and non-point sources of pollution loading to streams. Fourth, hydrologists and atmospheric modellers have perceived weaknesses in the representation of hydrological processes in regional and global climate models, and developed global hydrological models to overcome the weaknesses of global climate models. Considerable progress in the development and application of global hydrological models has been achieved to date, however, large uncertainties still exist considering the model structure including large scale flow routing, parameterization, input data, etc. This presentation will focus on the global hydrological models, and the discussion includes (1) types of global hydrological models, (2) procedure of global hydrological model development

    To make this study self-contained, we briefly recall the key concepts of granular computing and demonstrate how this conceptual framework and its algorithmic fundamentals give rise to granular models. We discuss several representative formal setups used in describing and processing information granules including fuzzy sets, rough sets, and interval calculus. Key architectures of models dwell upon relationships among information granules. We demonstrate how information granularity and its optimization can be regarded as an important design asset to be exploited in system modeling and giving rise to granular models. With this regard, an important category of rule-based models along with their granular enrichments is studied in detail.

  20. Geologic Framework Model Analysis Model Report

    The purpose of this report is to document the Geologic Framework Model (GFM), Version 3.1 (GFM3.1) with regard to data input, modeling methods, assumptions, uncertainties, limitations, and validation of the model results, qualification status of the model, and the differences between Version 3.1 and previous versions. The GFM represents a three-dimensional interpretation of the stratigraphy and structural features of the location of the potential Yucca Mountain radioactive waste repository. The GFM encompasses an area of 65 square miles (170 square kilometers) and a volume of 185 cubic miles (771 cubic kilometers). The boundaries of the GFM were chosen to encompass the most widely distributed set of exploratory boreholes (the Water Table or WT series) and to provide a geologic framework over the area of interest for hydrologic flow and radionuclide transport modeling through the unsaturated zone (UZ). The depth of the model is constrained by the inferred depth of the Tertiary-Paleozoic unconformity. The GFM was constructed from geologic map and borehole data. Additional information from measured stratigraphy sections, gravity profiles, and seismic profiles was also considered. This interim change notice (ICN) was prepared in accordance with the Technical Work Plan for the Integrated Site Model Process Model Report Revision 01 (CRWMS M&O 2000). The constraints, caveats, and limitations associated with this model are discussed in the appropriate text sections that follow. The GFM is one component of the Integrated Site Model (ISM) (Figure l), which has been developed to provide a consistent volumetric portrayal of the rock layers, rock properties, and mineralogy of the Yucca Mountain site. The ISM consists of three components: (1) Geologic Framework Model (GFM); (2) Rock Properties Model (RPM); and (3) Mineralogic Model (MM). The ISM merges the detailed project stratigraphy into model stratigraphic units that are most useful for the primary downstream models and the

    2016-05-01

    The University of California, Irvine, science team (Dr. Saewung Kim, Dr. Roger Seco, Dr. Alex Guenther, and Dr. Jim Smith) deployed a chemical ionization mass spectrometer system for hydroxyl radical (OH) and sulfuric acid quantifications. As part of the GoAmazon 2014/15 field campaign. Hydroxyl radical determines tropospheric oxidation capacity and had been expected to be very low in the pristine rain forest region such as the Brazilian Amazon because of the presence of significant levels of highly reactive biogenic volatile organic compounds and very low levels of NO, which is an OH recycling agent. However, several recent in situ OH observations provided by a laser-induced fluorescence system reported unaccountably high OH concentrations. To address this discrepancy, a series of laboratory and theoretical studies has postulated chemical reaction mechanisms of isoprene that may regenerate OH in photo-oxidation processes. Along with these efforts, potential artifacts on the laser induced fluorescence system from isoprene and its oxidation products also have been explored. Therefore, the first chemical ionization mass spectrometer observations at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility’s T3 site in Manacapuru, Brazil, are expected to provide a critical experimental constraint to address uncertainty in constraining oxidation capacity over pristine rain forest environments. In addition, we deployed a National Center for Atmospheric Research (NCAR) proton transfer reaction time-of-flight mass spectrometer to characterize atmospheric volatile organic compound levels, especially isoprene and its oxidation products, which are critical input parameters for box modeling to simulate OH with different isoprene photo-oxidation schemes. As there has been no report on noticeable new particle formation events, our first in situ sulfuric acid observations in the Amazon rain forest were expected to constrain the

  13. Interfacing materials models with fire field models

    Energy Technology Data Exchange (ETDEWEB)

    Nicolette, V.F.; Tieszen, S.R.; Moya, J.L.

    1995-12-01

    For flame spread over solid materials, there has traditionally been a large technology gap between fundamental combustion research and the somewhat simplistic approaches used for practical, real-world applications. Recent advances in computational hardware and computational fluid dynamics (CFD)-based software have led to the development of fire field models. These models, when used in conjunction with material burning models, have the potential to bridge the gap between research and application by implementing physics-based engineering models in a transient, multi-dimensional tool. This paper discusses the coupling that is necessary between fire field models and burning material models for the simulation of solid material fires. Fire field models are capable of providing detailed information about the local fire environment. This information serves as an input to the solid material combustion submodel, which subsequently calculates the impact of the fire environment on the material. The response of the solid material (in terms of thermal response, decomposition, charring, and off-gassing) is then fed back into the field model as a source of mass, momentum and energy. The critical parameters which must be passed between the field model and the material burning model have been identified. Many computational issues must be addressed when developing such an interface. Some examples include the ability to track multiple fuels and species, local ignition criteria, and the need to use local grid refinement over the burning material of interest.

    The flow-field of a propane-air diffusion flame combustor with interior and exterior conjugate heat transfers was numerically studied.Results obtained from four combustion models,combined with the re-normalization group (RNG) k-ε turbulence model,discrete ordinates radiation model and enhanced wall treatment are presented and discussed.The results are compared with a comprehensive database obtained from a series of experimental measurements.The flow patterns and the recirculation zone length in the combustion chamber are accurately predicted,and the mean axial velocities are in fairly good agreement with the experimental data,particularly at downstream sections for all four combustion models.The mean temperature profiles are captured fairly well by the eddy dissipation (EDS),probability density function (PDF),and laminar flamelet combustion models.However,the EDS-finite-rate combustion model fails to provide an acceptable temperature field.In general,the flamelet model illustrates little superiority over the PDF model,and to some extent the PDF model shows better performance than the EDS model.

  17. Regularized Structural Equation Modeling.

    Science.gov (United States)

    Jacobucci, Ross; Grimm, Kevin J; McArdle, John J

    A new method is proposed that extends the use of regularization in both lasso and ridge regression to structural equation models. The method is termed regularized structural equation modeling (RegSEM). RegSEM penalizes specific parameters in structural equation models, with the goal of creating easier to understand and simpler models. Although regularization has gained wide adoption in regression, very little has transferred to models with latent variables. By adding penalties to specific parameters in a structural equation model, researchers have a high level of flexibility in reducing model complexity, overcoming poor fitting models, and the creation of models that are more likely to generalize to new samples. The proposed method was evaluated through a simulation study, two illustrative examples involving a measurement model, and one empirical example involving the structural part of the model to demonstrate RegSEM's utility.

    The concept of hydrologic and geomorphologic connectivity describes the processes and pathways which link sources (e.g. rainfall, snow and ice melt, springs, eroded areas and barren lands) to accumulation areas (e.g. foot slopes, streams, aquifers, reservoirs), and the spatial variations thereof. There are many examples of hydrological and sediment connectivity on a watershed scale; in consequence, a process-based understanding of connectivity is crucial to help managers understand their systems and adopt adequate measures for flood prevention, pollution mitigation and soil protection, among others. Modelling is often used as a tool to understand and predict fluxes within a catchment by complementing observations with model results. Catchment models should therefore be able to reproduce the linkages, and thus the connectivity of water and sediment fluxes within the systems under simulation. In modelling, a high level of spatial and temporal detail is desirable to ensure taking into account a maximum number of components, which then enables connectivity to emerge from the simulated structures and functions. However, computational constraints and, in many cases, lack of data prevent the representation of all relevant processes and spatial/temporal variability in most models. In most cases, therefore, the level of detail selected for modelling is too coarse to represent the system in a way in which connectivity can emerge; a problem which can be circumvented by representing fine-scale structures and processes within coarser scale models using a variety of approaches. This poster focuses on the results of ongoing discussions on modelling connectivity held during several workshops within COST Action Connecteur. It assesses the current state of the art of incorporating the concept of connectivity in hydrological and sediment models, as well as the attitudes of modellers towards this issue. The discussion will focus on the different approaches through which connectivity

  4. Integrity modelling of tropospheric delay models

    The effect of the neutral atmosphere on signal propagation is routinely estimated by various tropospheric delay models in satellite navigation. Although numerous studies can be found in the literature investigating the accuracy of these models, for safety-of-life applications it is crucial to study and model the worst case performance of these models using very low recurrence frequencies. The main objective of the INTegrity of TROpospheric models (INTRO) project funded by the ESA PECS programme is to establish a model (or models) of the residual error of existing tropospheric delay models for safety-of-life applications. Such models are required to overbound rare tropospheric delays and should thus include the tails of the error distributions. Their use should lead to safe error bounds on the user position and should allow computation of protection levels for the horizontal and vertical position errors. The current tropospheric model from the RTCA SBAS Minimal Operational Standards has an associated residual error that equals 0.12 meters in the vertical direction. This value is derived by simply extrapolating the observed distribution of the residuals into the tail (where no data is present) and then taking the point where the cumulative distribution has an exceedance level would be 10-7.While the resulting standard deviation is much higher than the estimated standard variance that best fits the data (0.05 meters), it surely is conservative for most applications. In the context of the INTRO project some widely used and newly developed tropospheric delay models (e.g. RTCA MOPS, ESA GALTROPO and GPT2W) were tested using 16 years of daily ERA-INTERIM Reanalysis numerical weather model data and the raytracing technique. The results showed that the performance of some of the widely applied models have a clear seasonal dependency and it is also affected by a geographical position. In order to provide a more realistic, but still conservative estimation of the residual

    Scientific models are frequently discussed in philosophy of science. A great deal of the discussion is centred on approximation, idealisation, and on how these models achieve their representational function. Despite the importance, distinct nature, and high presence of toy models, they have received little attention from philosophers. This paper hopes to remedy this situation. It aims to elevate the status of toy models: by distinguishing them from approximations and idealisations, by highlighting and elaborating on several ways the Kac ring, a simple statistical mechanical model, is used as a toy model, and by explaining why toy models can be used to successfully carry out important work without performing a representational function.

  7. Protein Models Comparator

    The process of comparison of computer generated protein structural models is an important element of protein structure prediction. It has many uses including model quality evaluation, selection of the final models from a large set of candidates or optimisation of parameters of energy functions used in template free modelling and refinement. Although many protein comparison methods are available online on numerous web servers, their ability to handle a large scale model comparison is often very limited. Most of the servers offer only a single pairwise structural comparison, and they usually do not provide a model-specific comparison with a fixed alignment between the models. To bridge the gap between the protein and model structure comparison we have developed the Protein Models Comparator (pm-cmp). To be able to deliver the scalability on demand and handle large comparison experiments the pm-cmp was implemented "in the cloud". Protein Models Comparator is a scalable web application for a fast distributed comp...

  8. Nonuniform Markov models

    1996-01-01

    A statistical language model assigns probability to strings of arbitrary length. Unfortunately, it is not possible to gather reliable statistics on strings of arbitrary length from a finite corpus. Therefore, a statistical language model must decide that each symbol in a string depends on at most a small, finite number of other symbols in the string. In this report we propose a new way to model conditional independence in Markov models. The central feature of our nonuniform Markov model is that it makes predictions of varying lengths using contexts of varying lengths. Experiments on the Wall Street Journal reveal that the nonuniform model performs slightly better than the classic interpolated Markov model. This result is somewhat remarkable because both models contain identical numbers of parameters whose values are estimated in a similar manner. The only difference between the two models is how they combine the statistics of longer and shorter strings. Keywords: nonuniform Markov model, interpolated Markov m...

    CERN Document Server

    Schneider, Christoph

    2011-01-01

    In the field of Business Process Management formal models for the control flow of business processes have been designed since more than 15 years. Which methods are best suited to verify the bulk of these models? The first step is to select a formal language which fixes the semantics of the models. We adopt the language of Boolean systems as reference language for Boolean process models. Boolean systems form a simple subclass of coloured Petri nets. Their characteristics are low tokens to model explicitly states with a subsequent skipping of activations and arbitrary logical rules of type AND, XOR, OR etc. to model the split and join of the control flow. We apply model checking as a verification method for the safeness and liveness of Boolean systems. Model checking of Boolean systems uses the elementary theory of propositional logic, no modal operators are needed. Our verification builds on a finite complete prefix of a certain T-system attached to the Boolean system. It splits the processes of the Boolean sy...

    Full Text Available In this work, surface course aging was modeled by Response Surface Methodology (RSM. The Marshall specimens were placed in a conventional oven for time and temperature conditions established on the basis of the environment factors of the region where the surface course is constructed by AC-20 from the Ing. Antonio M. Amor refinery. Volatilized material (VM, load resistance increment (ΔL and flow resistance increment (ΔF models were developed by the RSM. Cylindrical specimens with real aging were extracted from the surface course pilot to evaluate the error of the models. The VM model was adequate, in contrast (ΔL and (ΔF models were almost adequate with an error of 20 %, that was associated with the other environmental factors, which were not considered at the beginning of the research.

  20. Model Validation Status Review

    Energy Technology Data Exchange (ETDEWEB)

    2001-11-28

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

  2. Practical Marginalized Multilevel Models.

    Griswold, Michael E; Swihart, Bruce J; Caffo, Brian S; Zeger, Scott L

    2013-01-01

    Clustered data analysis is characterized by the need to describe both systematic variation in a mean model and cluster-dependent random variation in an association model. Marginalized multilevel models embrace the robustness and interpretations of a marginal mean model, while retaining the likelihood inference capabilities and flexible dependence structures of a conditional association model. Although there has been increasing recognition of the attractiveness of marginalized multilevel models, there has been a gap in their practical application arising from a lack of readily available estimation procedures. We extend the marginalized multilevel model to allow for nonlinear functions in both the mean and association aspects. We then formulate marginal models through conditional specifications to facilitate estimation with mixed model computational solutions already in place. We illustrate the MMM and approximate MMM approaches on a cerebrovascular deficiency crossover trial using SAS and an epidemiological study on race and visual impairment using R. Datasets, SAS and R code are included as supplemental materials.

    With the development of human society, the social hub enlarges beyond one community to the extent that the world is deemed as a community as a whole. Communication, therefore, plays an increasingly important role in our daily life. As a consequence, communication model or the definition of which is not so much a definition as a guide in communication. However, some existed communication models are not as practical as it was. This paper tries to make an overall contrast among three communication models Coded Model, Gable Communication Model and Ostensive Inferential Model, to see how they assist people to comprehend verbal and non -verbal communication.

    2009-12-01

    This Letter addresses the problem of modeling the highway systems of different countries by using complex networks formalism. More specifically, we compare two traditional geographical models with a modified geometrical network model where paths, rather than edges, are incorporated at each step between the origin and the destination vertices. Optimal configurations of parameters are obtained for each model and used for the comparison. The highway networks of Australia, Brazil, India, and Romania are considered and shown to be properly modeled by the modified geographical model.

    Full Text Available Besides analyzing capitalist societies historically and thinking of them in terms of phases or stages, we may compare different models or varieties of capitalism. In this paper I survey the literature on this subject, and distinguish the classification that has a production or business approach from those that use a mainly political criterion. I identify five forms of capitalism: among the rich countries, the liberal democratic or Anglo-Saxon model, the social or European model, and the endogenous social integration or Japanese model; among developing countries, I distinguish the Asian developmental model from the liberal-dependent model that characterizes most other developing countries, including Brazil.

  9. Holographic twin Higgs model.

    Science.gov (United States)

    Geller, Michael; Telem, Ofri

    2015-05-15

    We present the first realization of a "twin Higgs" model as a holographic composite Higgs model. Uniquely among composite Higgs models, the Higgs potential is protected by a new standard model (SM) singlet elementary "mirror" sector at the sigma model scale f and not by the composite states at m_{KK}, naturally allowing for m_{KK} beyond the LHC reach. As a result, naturalness in our model cannot be constrained by the LHC, but may be probed by precision Higgs measurements at future lepton colliders, and by direct searches for Kaluza-Klein excitations at a 100 TeV collider.

    2013-01-01

    During my internship at NASA, I was a model developer for Ground Support Equipment (GSE). The purpose of a model developer is to develop and unit test model component libraries (fluid, electrical, gas, etc.). The models are designed to simulate software for GSE (Ground Special Power, Crew Access Arm, Cryo, Fire and Leak Detection System, Environmental Control System (ECS), etc. .) before they are implemented into hardware. These models support verifying local control and remote software for End-Item Software Under Test (SUT). The model simulates the physical behavior (function, state, limits and 110) of each end-item and it's dependencies as defined in the Subsystem Interface Table, Software Requirements & Design Specification (SRDS), Ground Integrated Schematic (GIS), and System Mechanical Schematic.(SMS). The software of each specific model component is simulated through MATLAB's Simulink program. The intensiv model development life cycle is a.s follows: Identify source documents; identify model scope; update schedule; preliminary design review; develop model requirements; update model.. scope; update schedule; detailed design review; create/modify library component; implement library components reference; implement subsystem components; develop a test script; run the test script; develop users guide; send model out for peer review; the model is sent out for verifictionlvalidation; if there is empirical data, a validation data package is generated; if there is not empirical data, a verification package is generated; the test results are then reviewed; and finally, the user. requests accreditation, and a statement of accreditation is prepared. Once each component model is reviewed and approved, they are intertwined together into one integrated model. This integrated model is then tested itself, through a test script and autotest, so that it can be concluded that all models work conjointly, for a single purpose.

    The purpose of this report is to document the biosphere model, the Environmental Radiation Model for Yucca Mountain, Nevada (ERMYN), which describes radionuclide transport processes in the biosphere and associated human exposure that may arise as the result of radionuclide release from the geologic repository at Yucca Mountain. The biosphere model is one of the process models that support the Yucca Mountain Project (YMP) Total System Performance Assessment (TSPA) for the license application (LA), TSPA-LA. The ERMYN provides the capability of performing human radiation dose assessments. This report documents the biosphere model, which includes: (1) Describing the reference biosphere, human receptor, exposure scenarios, and primary radionuclides for each exposure scenario (Section 6.1); (2) Developing a biosphere conceptual model using site-specific features, events, and processes (FEPs) (Section 6.2), the reference biosphere (Section 6.1.1), the human receptor (Section 6.1.2), and approximations (Sections 6.3.1.4 and 6.3.2.4); (3) Building a mathematical model using the biosphere conceptual model (Section 6.3) and published biosphere models (Sections 6.4 and 6.5); (4) Summarizing input parameters for the mathematical model, including the uncertainty associated with input values (Section 6.6); (5) Identifying improvements in the ERMYN compared with the model used in previous biosphere modeling (Section 6.7); (6) Constructing an ERMYN implementation tool (model) based on the biosphere mathematical model using GoldSim stochastic simulation software (Sections 6.8 and 6.9); (7) Verifying the ERMYN by comparing output from the software with hand calculations to ensure that the GoldSim implementation is correct (Section 6.10); (8) Validating the ERMYN by corroborating it with published biosphere models; comparing conceptual models, mathematical models, and numerical results (Section 7).

    Rouder, Jeffrey N; Engelhardt, Christopher R; McCabe, Simon; Morey, Richard D

    2016-12-01

    Analysis of variance (ANOVA), the workhorse analysis of experimental designs, consists of F-tests of main effects and interactions. Yet, testing, including traditional ANOVA, has been recently critiqued on a number of theoretical and practical grounds. In light of these critiques, model comparison and model selection serve as an attractive alternative. Model comparison differs from testing in that one can support a null or nested model vis-a-vis a more general alternative by penalizing more flexible models. We argue this ability to support more simple models allows for more nuanced theoretical conclusions than provided by traditional ANOVA F-tests. We provide a model comparison strategy and show how ANOVA models may be reparameterized to better address substantive questions in data analysis.

    Niepostyn, Stanisław J.

    2015-09-01

    The goal of the MDA is to produce software systems from abstract models in a way where human interaction is restricted to a minimum. These abstract models are based on the UML language. However, the semantics of UML models is defined in a natural language. Subsequently the verification of consistency of these diagrams is needed in order to identify errors in requirements at the early stage of the development process. The verification of consistency is difficult due to a semi-formal nature of UML diagrams. We propose automatic verification of consistency of the series of UML diagrams originating from abstract models implemented with our consistency rules. This Consistent Model Driven Architecture approach enables us to generate automatically complete workflow applications from consistent and complete models developed from abstract models (e.g. Business Context Diagram). Therefore, our method can be used to check practicability (feasibility) of software architecture models.

    2011-10-01

    Full Text Available Species distribution models are increasing in popularity for mapping suitable habitat for species of management concern. Many investigators now recognize that extrapolations of these models with geographic information systems (GIS might be sensitive to the environmental bounds of the data used in their development, yet there is no recommended best practice for “clamping” model extrapolations. We relied on two commonly used modeling approaches: classification and regression tree (CART and maximum entropy (Maxent models, and we tested a simple alteration of the model extrapolations, bounding extrapolations to the maximum and minimum values of primary environmental predictors, to provide a more realistic map of suitable habitat of hybridized Africanized honey bees in the southwestern United States. Findings suggest that multiple models of bounding, and the most conservative bounding of species distribution models, like those presented here, should probably replace the unbounded or loosely bounded techniques currently used [Current Zoology 57 (5: 642–647, 2011].

    The report describes a simple comparison of two CCF-models, the ECLM, and the Beta-model. The objective of the comparison is to identify differences in the results of the models by applying the models in some simple test data cases. The comparison focuses mainly on theoretical aspects of the above mentioned CCF-models. The properties of the model parameter estimates in the data cases is also discussed. The practical aspects in using and estimating CCFmodels in real PSA context (e.g. the data interpretation, properties of computer tools, the model documentation) are not discussed in the report. Similarly, the qualitative CCF-analyses needed in using the models are not discussed in the report. (au)

    Multithreaded technique is the developing trend of high performance processor. Memory consistency model is essential to the correctness, performance and complexity of multithreaded processor. The chip multithreaded consistency model adapting to multithreaded processor is proposed in this paper. The restriction imposed on memory event ordering by chip multithreaded consistency is presented and formalized. With the idea of critical cycle built by Wei-Wu Hu, we prove that the proposed chip multithreaded consistency model satisfies the criterion of correct execution of sequential consistency model. Chip multithreaded consistency model provides a way of achieving high performance compared with sequential consistency model and ensures the compatibility of software that the execution result in multithreaded processor is the same as the execution result in uniprocessor. The implementation strategy of chip multithreaded consistency model in Godson-2 SMT processor is also proposed. Godson-2 SMT processor supports chip multithreaded consistency model correctly by exception scheme based on the sequential memory access queue of each thread.

    Full Text Available In this paper we analyze complexity of time limits we can find especially in regulated processes of public administration. First we review the most popular process modeling languages. There is defined an example scenario based on the current Czech legislature which is then captured in discussed process modeling languages. Analysis shows that the contemporary process modeling languages support capturing of the time limit only partially. This causes troubles to analysts and unnecessary complexity of the models. Upon unsatisfying results of the contemporary process modeling languages we analyze the complexity of the time limits in greater detail and outline lifecycles of a time limit using the multiple dynamic generalizations pattern. As an alternative to the popular process modeling languages there is presented PSD process modeling language, which supports the defined lifecycles of a time limit natively and therefore allows keeping the models simple and easy to understand.

    Species distribution models are increasing in popularity for mapping suitable habitat for species of management concern. Many investigators now recognize that extrapolations of these models with geographic information systems (GIS) might be sensitive to the environmental bounds of the data used in their development, yet there is no recommended best practice for "clamping" model extrapolations. We relied on two commonly used modeling approaches: classification and regression tree (CART) and maximum entropy (Maxent) models, and we tested a simple alteration of the model extrapolations, bounding extrapolations to the maximum and minimum values of primary environmental predictors, to provide a more realistic map of suitable habitat of hybridized Africanized honey bees in the southwestern United States. Findings suggest that multiple models of bounding, and the most conservative bounding of species distribution models, like those presented here, should probably replace the unbounded or loosely bounded techniques currently used [Current Zoology 57 (5): 642-647, 2011].

  15. The ATLAS Analysis Model

    CERN Multimedia

    Amir Farbin

    The ATLAS Analysis Model is a continually developing vision of how to reconcile physics analysis requirements with the ATLAS offline software and computing model constraints. In the past year this vision has influenced the evolution of the ATLAS Event Data Model, the Athena software framework, and physics analysis tools. These developments, along with the October Analysis Model Workshop and the planning for CSC analyses have led to a rapid refinement of the ATLAS Analysis Model in the past few months. This article introduces some of the relevant issues and presents the current vision of the future ATLAS Analysis Model. Event Data Model The ATLAS Event Data Model (EDM) consists of several levels of details, each targeted for a specific set of tasks. For example the Event Summary Data (ESD) stores calorimeter cells and tracking system hits thereby permitting many calibration and alignment tasks, but will be only accessible at particular computing sites with potentially large latency. In contrast, the Analysis...

    2005-01-01

    The hysteresis of the magnetostrictive actuator was studied. A mathematical model of the hysteresis loop was obtained on the basis of experiment. This model depends on the frequency and the amplitude of the alternating current inputted to the magnetostrictive actuator. Based on the model, the effect of hysteresis on dynamic output of the magnetostrictive actuator was investigated. Then how to consider hysteresis and establish a dynamic model of a magnetostrictive actuator system is discussed when a practical system was designed and applied.

  14. Crushed Salt Constitutive Model

    Energy Technology Data Exchange (ETDEWEB)

    Callahan, G.D.

    1999-02-01

    The constitutive model used to describe the deformation of crushed salt is presented in this report. Two mechanisms -- dislocation creep and grain boundary diffusional pressure solution -- are combined to form the basis for the constitutive model governing the deformation of crushed salt. The constitutive model is generalized to represent three-dimensional states of stress. Upon complete consolidation, the crushed-salt model reproduces the Multimechanism Deformation (M-D) model typically used for the Waste Isolation Pilot Plant (WIPP) host geological formation salt. New shear consolidation tests are combined with an existing database that includes hydrostatic consolidation and shear consolidation tests conducted on WIPP and southeastern New Mexico salt. Nonlinear least-squares model fitting to the database produced two sets of material parameter values for the model -- one for the shear consolidation tests and one for a combination of the shear and hydrostatic consolidation tests. Using the parameter values determined from the fitted database, the constitutive model is validated against constant strain-rate tests. Shaft seal problems are analyzed to demonstrate model-predicted consolidation of the shaft seal crushed-salt component. Based on the fitting statistics, the ability of the model to predict the test data, and the ability of the model to predict load paths and test data outside of the fitted database, the model appears to capture the creep consolidation behavior of crushed salt reasonably well.

  16. Modeling agriculture in the Community Land Model

    Directory of Open Access Journals (Sweden)

    B. Drewniak

    2013-04-01

    Full Text Available The potential impact of climate change on agriculture is uncertain. In addition, agriculture could influence above- and below-ground carbon storage. Development of models that represent agriculture is necessary to address these impacts. We have developed an approach to integrate agriculture representations for three crop types – maize, soybean, and spring wheat – into the coupled carbon–nitrogen version of the Community Land Model (CLM, to help address these questions. Here we present the new model, CLM-Crop, validated against observations from two AmeriFlux sites in the United States, planted with maize and soybean. Seasonal carbon fluxes compared well with field measurements for soybean, but not as well for maize. CLM-Crop yields were comparable with observations in countries such as the United States, Argentina, and China, although the generality of the crop model and its lack of technology and irrigation made direct comparison difficult. CLM-Crop was compared against the standard CLM3.5, which simulates crops as grass. The comparison showed improvement in gross primary productivity in regions where crops are the dominant vegetation cover. Crop yields and productivity were negatively correlated with temperature and positively correlated with precipitation, in agreement with other modeling studies. In case studies with the new crop model looking at impacts of residue management and planting date on crop yield, we found that increased residue returned to the litter pool increased crop yield, while reduced residue returns resulted in yield decreases. Using climate controls to signal planting date caused different responses in different crops. Maize and soybean had opposite reactions: when low temperature threshold resulted in early planting, maize responded with a loss of yield, but soybean yields increased. Our improvements in CLM demonstrate a new capability in the model – simulating agriculture in a realistic way, complete with

    The Mechanics of Materials Model (MOMM) is a three-dimensional inelastic structural analysis code for use as an early design stage tool for hot section components. MOMM is a stiffness method finite element code that uses a network of beams to characterize component behavior. The MOMM contains three material models to account for inelastic material behavior. These include the simplified material model, which assumes a bilinear stress-strain response; the state-of-the-art model, which utilizes the classical elastic-plastic-creep strain decomposition; and Walker's viscoplastic model, which accounts for the interaction between creep and plasticity that occurs under cyclic loading conditions.
