  1. Where the Gulf Stream ends; La ou finit le Gulf Stream - Site de Gremikha

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2007-07-01

    The Gremikha site is an old naval base and nuclear submarines refueling facility, without any operational activity and partially abandoned for 15 years, located on the East of the Kola peninsula at about 160 km of Mourmansk. It was mainly used for the maintenance of the submarines of the Soviet fleet, and in particular those of the 'alfa' class having a liquid metal cooled (bismuth/lead) fast reactor. The base, today under the responsibility of SevRAO (a daughter company of Rosatom, is in a dramatic situation which represents a threat for the environment. Moreover, there exists a risk of diversion of the nuclear materials which are stored in non-secure conditions. The CEA project fits into the site rehabilitation program which should lead to the decontamination and closing down of the site by 2015. The operations to be performed are the following: recovery of the 'alpha' reactor cores, of the spent fuels of PWR propulsion reactors, of the solid and liquid radioactive wastes, and the cleansing of the site. A radiological and technological status of the site was performed between 2005 and 2007. The feasibility study was launched in December 2006 and is on the way of completion. It allows to define the operations to be performed, the technical and financial means to be implemented, and the schedule of realisation. The Kurchatov Institute (Moscow) is the coordinator of the site operations. France is financing the realisation of the status and the feasibility study. The results of this study will allow to determine the share of works supported by the different donors (France, the BERD (NDEP), Norway and Italy). This DVD presents a documentary about the Gremikha site, its radiological situation and the first remedial actions carried out so far. (J.S.)

  3. Finite-time compressibility as an agent of frequent spontaneous patch formation in the surface layer: A case study for the Gulf of Finland, the Baltic Sea.

    Giudici, Andrea; Soomere, Tarmo

    2014-12-15

    We explore the possibilities for spontaneous formation of surface patches with high concentrations of contaminants through time correlations of the convergence field and the Lagrangian transport. The test area is the Gulf of Finland, the Baltic Sea, where surface velocity fields show extensive convergence. The flow properties are extracted from 3D velocity fields simulated for 1987-1991 using the OAAS model with a resolution of 1 mile. The focus is on the spatial distribution of the areas in which the values of finite-time flow compressibility of surface velocity fields exceed the threshold for clustering of floats. The distribution of such areas is asymmetric, with likely areas of patch formation located predominantly in the southern and eastern regions of the gulf. Out of nine areas of likely patch formation, six are located along the coast in regions of frequent downwelling, while three are identified in the central region of the gulf.

    Full Text Available This paper reports the application of using a skirted foundation system to study the behavior of foundations with structural skirts adjacent to a sand slope and subjected to earthquake loading. The effect of the adopted skirts to safeguard foundation and slope from collapse is studied. The skirts effect on controlling horizontal soil movement and decreasing pore water pressure beneath foundations and beside the slopes during earthquake is investigated. This technique is investigated numerically using finite element analysis. A four story reinforced concrete building that rests on a raft foundation is idealized as a two-dimensional model with and without skirts. A two dimensional plain strain program PLAXIS, (dynamic version is adopted. A series of models for the problem under investigation were run under different skirt depths and lactation from the slope crest. The effect of subgrade relative density and skirts thickness is also discussed. Nodal displacement and element strains were analyzed for the foundation with and without skirts and at different studied parameters. The research results showed a great effectiveness in increasing the overall stability of the slope and foundation. The confined soil footing system by such skirts reduced the foundation acceleration therefore it can be tended to damping element and relieved the transmitted disturbance to the adjacent slope. This technique can be considered as a good method to control the slope deformation and decrease the slope acceleration during earthquakes.

    2002-10-01

    Full Text Available À partir de plusieurs écrits sur le modèle québécois et le Québec Inc., l’article montre que ces termes prennent plusieurs significations selon les auteurs. Ainsi, pour certains, ils traduisent un corporatiste, un véritable réseau ou un nationalisme économique ; pour d’autres, ils sont l’expression de la présence française en Amérique du nord ou encore un modèle d’émancipation d’un peuple et d’entreprises francophones. Le modèle de développement émerge des grands acteurs socio-économiques de ces dernières soixante années et ses caractéristiques permettent de saisir la notion d’intérêt général comme étant l’expression d’une communauté de personnes et non d’un marché. Plus qu’un concept qui chapeaute une classe d’affaire, Québec Inc serait un véritable projet de société et l’expression d’un modèle de développement fondé sur une alliance particulière entre les pouvoirs économiques public et privé dont l’objectif a été et continu d’être la poursuite d’une politique de croissance par la prise en main des leviers économiques du Québec. Enfin, il n’est rien d’autre qu’un désir "naturel" de concertation dans un monde où le regroupement des forces et des intelligences s’impose. Mais pour un renouvellement du modèle, un partage d’objectifs de la part des acteurs impliqués s’avère important de même qu’une "recapitalisation" sociale. L’article se termine en soulignant l’importance de la concertation et de la solidarité comme du capital social dont un nouveau modèle québécois dans un contexte actuel ne peut en faire l’économie.From several papers on the Quebecois model and Quebec Inc ., the article shows that these terms take several meanings according to the authors.

  9. Study of the particulate matter transfer and dumping using 210 Po et le 210 Pb. Application to the Gulf of Biscary (NE Atlantic Ocean) and the Gulf of Lion (NW Mediterranean Sea) continental margins

    1995-01-01

    210 Po and 210 Pb activities and fluxes were measured on seawater, sediment-trapped material collected during one year and sediment. Focalization of 210 Pb is clearly noticed on the Cap-Ferret canyon (Gulf of Biscary) and the Lacaze-Duthiers canyon (western part of the Gulf of Lion). In both sites, 210 Pb fluxes in traps and sediment are always higher than 210 Pb flux available from atmospheric and in situ production. On the contrary, Grand-Rhone canyon and its adjacent open slope exhibit a 210 Pb budget near equilibrium in the near-bottom sediment traps, but focalization is important in the sediment. For the entire Gulf of Lion margin, focalization of 210 Pb in the sediment occurred principally between 500 and 1500 m water depth on the slope, and on the middle shelf mud-patch. 210 Po and 210 Pb have been used in the Cap Ferret and Grand-Rhone canyons to characterize the origin of the particulate trapped material. Two main sources feed the water column. The first source, localized in surface waters, is constituted by biogenic particles from primary production and lithogenic material. The second source, deeper, is due to resuspension at the shelf break and/or on the open slope. In each site, 210 Po and 210 Pb activities of the trapped particles did not show any relations with the major constituents. Quantity of particles appeared to be the main factor regulating adsorption processes of these nuclides. Sedimentation rates based on 210 Po profiles decreased with increasing water depth, from 0.4 ti 0.06 cm y-1 on the Cap Ferret canyon (400 to 3000 m water depth) and from 0.5 to 0.05 cm y-1 for the entire Gulf of Lion margin (50 to 2000 m water depth).

    2012-05-01

    Full Text Available La figure du perroquet occupe une position ambiguë face à la question de la traduction. Il est capable d’imiter des paroles en toutes les langues, mais il n’est capable d’en comprendre aucune — il ne peut que répéter des sons, c’est-à-dire des signifiants. Le traducteur semble faire le contraire quand il passe d’une langue à une autre en tâchant de transmettre une signification semblable par d’autres signes. L’article vise à discuter lele du traducteur et sa relation, éventuellement équivoque, au perroquet, en analysant la traduction allemande de Trois Contes par André Stoll et Cora van Kleffens. Un décalage au niveau sémantique peut éclairer l’interprétation du texte, par exemple en explicitant des allusions sous-jacentes, tandis que le transfert de la syntaxe française en allemand pose souvent des problèmes considérables. Comment le traducteur peut-il reproduire des structures syntaxiques qui n’existent pas en allemand, mais qui ne cessent de revenir dans le texte français ? Que faire si le texte se met à jouer au perroquet et finit par se singer lui-même ? André Stoll et Cora van Kleffens ont su trouver des stratégies pour affronter ces difficultés.The figure of the parrot holds an ambiguous position towards the question of translation. It is able to imitate all languages, but it will never understand any of them – its only skill is to mimic sounds, i.e. mere signifiers. On the contrary, the translator seems to be the antithesis of the parrot when he moves from one language to another. He endeavours to convey a similar meaning, but by different signs. The article aims at discussing the role of the translator and his or her eventually equivocal relation to the parrot by means of analysing the German translation of Trois Contes by André Stoll and Cora van Kleffens. Whereas a semantic divergence can result in a different tendency on the level of interpretation, as in the case of an underlying

    2000-09-29

    This thesis presents a detailed overview of the thermodynamical properties of the model of Nambu and Jona-Lasinio. In fact, this model can be interpreted as a low energy approximation of QCD. The NJL model has the advantage to be solvable at finite temperature and density. Comparison with QCD lattice calculations show that the NJL model reproduces correctly the feature of chiral symmetry breaking and restoration. We present the chiral phase diagram of the NJL model for three flavors and study the influence of the parameters on the order of the phase transition. The properties of the mesons in a hot and dense medium are another topic of this thesis. We discuss the behaviour of the chiral partners and the influence of the symmetries. A point of special interest are the masses of the kaons in a dense medium. We compare the masses of the kaons with other models like RMF and ChPT. The last part of the thesis is devoted to the low temperature - high density region of the QCD phase diagram. In this region, the formation of a diquark condensate and a superconducting phase are expected. We discuss the structure of the diquark condensate and present the results of the numerical calculations at finite temperature and density. (author)

    Mélanie JECKER

    2010-05-01

    Full Text Available La fin du Moyen Âge fascine. Deux facteurs principaux expliquent l’attraction qu’exerce cette période : elle apparaît d’une part comme un moment historique riche car double, phase de transition entre le Moyen Âge et la Renaissance, où se mêlent des cadres de représentation anciens et nouveaux. L’insinuation d’une pensée humaniste balbutiante s’y traduirait notamment par l’émergence de la notion d’individu, qui constitue l’un des objets de ce travail. Il faut invoquer, d’autre part, l’image macabre d’un bas Moyen Âge hanté par l’idée de la maladie et de la mort depuis l’épidémie de peste noire de 1348, obsédé par la brièveté de la vie humaine. Ces deux facettes de « l’automne du Moyen Âge » tel que l’évoque avec poésie Joan Huizinga sont-elles autre chose qu’une plaisante image d’Epinal? Cette étude cherche précisément à déterminer le degré de validité de ces deux topiques, à travers l’analyse de la représentation des âges de la vie dans un corpus bien défini, celui de la biographie chevaleresque castillane du XVe siècle. L’intérêt porté à l’individu, la conscience de la singularité impliquent en effet celle du caractère mouvant de la personne, or quel thème mieux que celui des âges permet de confirmer ou d’infirmer l’hypothèse du surgissement d’une nouvelle manière de concevoir l’homme, proprement « renaissante », en ce siècle de transition , La nature même du corpus retenu – des récits biographiques – suggère en effet une mutation dans l’appréhension de la personne, une attention prêtée à sa progressive transformation. L’étude de la représentation de la vieillesse, en particulier, révèle non seulement à quel point était alors réelle cette prétendue obsession de la déchéance physique et de la mortalité, mais aussi dans quelle mesure étaient soulignés et valorisés les changements individuels parallèles à l

Les aspects littéraires de l’ouvrage (beauté de l’écriture, usage des images, de l’analogie, etc. ne sont pas des accessoires, mais des outils indispensables à l’élaboration d’un authentique savoir sur les abeilles, c’est-à-dire un savoir qui reconnaît la part d’inconnu et le mystère qui subsistent en dépit de toutes les explications physiques et mécaniques que l’on peut par ailleurs donner des phénomènes observés. Etre scientifique, dans cette perspective, c’est-à-dire donner à connaître, c’est donc être littéraire. Cette conception de la science repose en dernière instance sur une conception philosophique de l’univers comme un tout où toutes choses sont reliées, unies, par des relations d’analogies, ce qui fonde et justifie l’emploi d’un style symboliste.The life of bees, one of Maeterlinck’s works, is together a scientific and literary book, not because of it scientific exactness and its literary style, but for the reason it suggests the unity of both these domains. Literay’s aspects of this work (writing’s beauty, use of images, analogy, etc. are not secondary but necessary to elaborate an authentic knowledge about bees, that means a knowledge which admit the unknown part and the mistery that subsist despite all the physical and mechanical explanations we can give moreover about the observed phenomenons. Be a scientist, in this sense, that is give something to know, therefore means be literary. Finally, this conception of science consist in a philosophiacl conception of Universe as a whole where everything links together, and is united by analogical relations, that base and justify the use of a symbolist style.

    This paper reports that reports of damage caused by Hurricane Andrew were leveling off last week at the U.S. Minerals Management Service as Gulf of Mexico operators pressed ahead with repairs. The hurricane struck South Florida Aug. 4, churned west into the gulf, then swung north and hit the South Louisiana coast Aug. 5. By the close of business Sept. 8 MMS had received damage reports covering 83 pipeline segments and 193 platforms and satellite installations. MMS last week estimated about 500 MMcfd of gas production had been restored in the gulf and 100,000-150,000 b/d of oil. Production still lost as a result of Andrew was estimated at 2-2.5 bcfd of gas and 90,000-120 b/d of oil.

    2013-11-01

    Full Text Available Le théoricien James Hans définit le jeu comme une déconstruction structurante, un processus de perpétuelle remise en question. Dans Le Mangeur (2005 de Ying Chen, la narratrice revit un épisode d’une de ses vies passées où elle meurt mangée, avalée, par son père, descendant dans le « tunnel » du ventre de ce dernier. Cependant, suite à cet événement, elle se retrouve dans un autre espace-temps où elle rencontre son mari, A.. Une équivalence s’établit dans le roman entre les éléments suivants : le ventre du père, les tableaux peints par ce dernier et l’espace-temps de A., et la fenêtre. Ces éléments deviennent des aires de jeu, remettant en question les concepts de l’intérieur et de l’extérieur et du créateur et de l’œuvre. En nous servant du texte « Le Tunnel » écrit par Ying Chen, nous démontrerons que cette notion du jeu s’applique également à l’ensemble de son œuvre.

    In recent years, the Gulf of Mexico (GOM) has seen significant deepwater growth. An overview of the GOM deepwater leaseholds by Shell and developments by competing companies is presented. Deepwater GOM developments, total production from the shelf and from deepwater wells, new offshore pipeline capacity and ownership, and processing plant capacity are also discussed. Significant deepwater growth in the Gulf is anticipated. Despite significant economic and technological challenges, the area is judged to be the prime exploration and production opportunity in the lower 48 states of the USA. tabs., figs

  2. Issues related to seismic surveys in the Estuary and Gulf of St. Lawrence : public inquiry report; Les enjeux lies aux leves sismiques dans l'estuaire et le golfe du Saint-Laurent : rapport d'enquete et d'audience publique

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2004-08-01

    Quebec's Office of Public Inquiry on the Environment (Bureau d'audiences publiques sur l'environnement) conducted public hearings on the environmental issues associated with seismic surveys carried out in the Gulf of St. Lawrence and its estuaries for the purpose of petroleum and natural gas exploration. The inquiry focused on the effect of sound waves on aquatic ecosystems and marine organisms and the associated environmental, social and economic consequences of seismic surveys. Environmental groups, scientists, fishermen and the maritime tourist industry have been concerned with the impact of seismic surveys in the Estuary and the Gulf of St. Lawrence since the autumn of 2002, when Hydro-Quebec publicized its 2002-2010 plan for oil and gas exploration and when Geophysical Service Inc. received a mandate from Hydro-Quebec to carry out seismic surveys in the area. This report presents 10 recommendations and 16 opinions resulting from 18 public hearings held in communities along the Gulf of St. Lawrence. Although the thousands of kilometres of seismic survey lines acquired in the Estuary and the Gulf of St. Lawrence since 1960 do not seem to have had any visible impact on the marine environment, the Commission has taken a precautionary approach and recommends that some practices should be limited until a review of literature demonstrates that seismic surveys do not affect the ecological integrity of the St. Lawrence for fisheries or ecotourism. 16 refs., 9 tabs., 5 figs., 2 appendices.

    In this paper Garrett's theory of tides in gulfs is extended so that its formalism includes the free oscillations (seiches) of the gulf. The elevation of the free surface zeta and the velocity field u are obtained in a rectangular, one-dimensional gulf opening into an infinite ocean. An application of the results to the Adriatic sea can explain qualitatively the long life of the uninodal seiche of that basin. (author)

    This paper reports that Gulf of Mexico operators last week were gradually restoring production at installations struck by Hurricane Andrew. The Minerals Management Service continued receiving reports of more damage. By the end of the day Sept. 8, MMS had received reports of damage to 83 pipeline segments and 193 platforms and satellite installations. Damage reports listed 112 installations with structural damage, 13 platforms toppled and five leaning, and 30 satellite platforms toppled and 33 leaning. But despite the extent of damage the storm inflicted on oil and gas installations in the gulf, it pales in comparison to the misery and suffering the storm caused in Florida and Louisiana, an oil company official said

    This paper reports that reports of damage by Hurricane Andrew escalated last week as operators stepped up inspections of oil and gas installations in the Gulf of Mexico. By midweek, companies operating in the gulf and South Louisiana were beginning to agree that earlier assessments of damage only scratched the surface. Damage reports included scores of lost, toppled, or crippled platforms, pipeline ruptures, and oil slicks. By midweek the U.S. coast Guard had received reports of 79 oil spills. Even platforms capable of resuming production in some instances were begin curtailed because of damaged pipelines. Offshore service companies the another 2-4 weeks could be needed to fully assess Andrew's wrath. Lack of personnel and equipment was slowing damage assessment and repair

    1992-01-01

    This paper reports that producers in the Gulf of Mexico and plant operators in South Louisiana last week were checking for damage wrought by Hurricane Andrew. In its wake Andrew left evacuated rigs and platforms in the gulf and shuttered plants across a wide swath of the Gulf Coast. Operations were beginning to return to normal late last week. Not all gulf operators, especially in the central gulf, expected to return to offshore facilities. And even producers able to book helicopters did not expect to be able to fully assess damage to all offshore installations before the weekend. MMS officials in Washington estimated that 37,500 offshore workers were evacuated from 700 oil and gas installations on the gulf's Outer Continental Shelf. Gulf oil and gas wells account for about 800,000 b/d of oil and one fourth of total U.S. gas production. MMS was awaiting an assessment of hurricane damage before estimating how soon and how much gulf oil and gas production would be restored

In our history from a black perspective, Christianity arrived through violent conquest from the west. Evidentially, this faith coincided with wars of dispossession and the ultimate defeat of black Africans. It is difficult to separate the violent defeat of black Africans from the arrival of Christian faith. This well-known statement within the circles of black Theology of liberation: When the white man arrived in our land he said, �let us pray and after prayer, when we opened our eyes, our land was taken and only the Bible was left in our hands,� captures the black sentiment of this history. Ironically, it was this Bible that black Africans used to wage their struggle for liberation up to the demise of apartheid in 1994.Nonetheless, political liberation is not enough as the struggle for economic liberation

    Full Text Available Alors que les deux grands festivals « historiques » du monde arabe, Carthage (JCC et Le Caire, sont entrés en décadence, on assiste depuis le début des années 2000 à une véritable explosion du phénomène festivalier dans le monde arabe. Le pays le plus en pointe est le Maroc, quoique de manière contrastée, avec une manifestation de prestige à Marrakech, et une nuée de petites manifestations. Dans les émirats du Golfe, la multiplication des festivals traduit une stratégie de communication plutôt qu’une volonté de développement culturel. Cette stratégie est fragilisée par la concurrence que se livrent les différents acteurs. Dans les autres pays arabes, on trouve une grande variété de situations sous le signe de la dispersion. Pourtant, l’accumulation de festivals (une centaine dans la région finit par avoir des effets d’ensemble, au-delà des buts, moyens et limites de chacun d’eux. Le phénomène festivalier, bien qu’inscrit dans des agendas locaux ou nationaux, génère de manière plus vaste des réseaux générationnels, financiers, de procédures d’expertise, de processus d’interrelation, géographiques mais aussi entre le cinéma et les autres arts ou médias.

    Science.gov (United States)

    Khare, Kedar; George, Nicholas

    2004-07-01

    We show that a fractional version of the finite Fourier transform may be defined by using prolate spheroidal wave functions of order zero. The transform is linear and additive in its index and asymptotically goes over to Namias's definition of the fractional Fourier transform. As a special case of this definition, it is shown that the finite Fourier transform may be inverted by using information over a finite range of frequencies in Fourier space, the inversion being sensitive to noise. Numerical illustrations for both forward (fractional) and inverse finite transforms are provided.

    1986-01-01

    We investigate the relation between finiteness of a four-dimensional quantum field theory and global supersymmetry. To this end we consider the most general quantum field theory and analyse the finiteness conditions resulting from the requirement of the absence of divergent contributions to the renormalizations of the parameters of the theory. In addition to the gauge bosons, both fermions and scalar bosons turn out to be a necessary ingredient in a non-trivial finite gauge theory. In all cases discussed, the supersymmetric theory restricted by two well-known constraints on the dimensionless couplings proves to be the unique solution of the finiteness conditions. (Author)

  1. Le genre comme rapport d’inégalité sociale dans le discours publicitaire

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Loin de se réduire à une simple transaction commerciale, une annonce publicitaire est un espace de croyances sur des identités, des rôles et des pratiques sociales. Au même titre que d’autres productions fictionnelles de la culture de masse, elle représente l’une des faces de ce miroir social alimenté par la circulation incessante d’attitudes et de croyances, affichant même s’il s’agit bien souvent pour cette dernière d’un positionnement ludique, un second monde peuplé par nos avatars. La publicité tout comme le fait la fiction télévisée définit l’horizon des possibles d’une communauté donnée. Ce qu’elles réalisent toutes deux c’est l’entrée de l’imaginaire dans le réel. Même si, à partir des années 70, s’opère un lent défigement des stéréotypes sexistes, le publicitaire ne se fera aucunement le porte-parole explicite d’une quelconque lutte féministe, il optera toujours pour une tactique ambivalente de double speak: des effets de décadrage mettant en exergue des situations délibérément décalées ou burlesques (Un homme qui change les couches de bébé! Un clown qui fait la lessive!, mais cristallisant des inégalités de rôles. En jouant tout à la fois sur le défigement et la réactivation des stéréotypes, c’est bien un rôle de passeur et de go between, qu’est assigné le publicitaire en se faisant l’arbitre ventriloque de ces conflits de légitimité et de construction identitaire qui agitent notre modernité.

  8. Temperature of the Gulf Stream

    Science.gov (United States)

    2002-01-01

    The Gulf Stream is one of the strong ocean currents that carries warm water from the sunny tropics to higher latitudes. The current stretches from the Gulf of Mexico up the East Coast of the United States, departs from North America south of the Chesapeake Bay, and heads across the Atlantic to the British Isles. The water within the Gulf Stream moves at the stately pace of 4 miles per hour. Even though the current cools as the water travels thousands of miles, it remains strong enough to moderate the Northern European climate. The image above was derived from the infrared measurements of the Moderate-resolution Imaging Spectroradiometer (MODIS) on a nearly cloud-free day over the east coast of the United States. The coldest waters are shown as purple, with blue, green, yellow, and red representing progressively warmer water. Temperatures range from about 7 to 22 degrees Celsius. The core of the Gulf Stream is very apparent as the warmest water, dark red. It departs from the coast at Cape Hatteras, North Carolina. The cool, shelf water from the north entrains the warmer outflows from the Chesapeake and Delaware Bays. The north wall of the Gulf Stream reveals very complex structure associated with frontal instabilities that lead to exchanges between the Gulf Stream and inshore waters. Several clockwise-rotating warm core eddies are evident north of the core of the Gulf Stream, which enhance the exchange of heat and water between the coastal and deep ocean. Cold core eddies, which rotate counter clockwise, are seen south of the Gulf Stream. The one closest to Cape Hatteras is entraining very warm Gulf Stream waters on its northwest circumference. Near the coast, shallower waters have warmed due to solar heating, while the deeper waters offshore are markedly cooler (dark blue). MODIS made this observation on May 8, 2000, at 11:45 a.m. EDT. For more information, see the MODIS-Ocean web page. The sea surface temperature image was created at the University of Miami using

    In this report, technologies for petroleum production and exploration enhancement in deepwater and mature fields are developed through basic and applied research by: (1) Designing new fluids to efficiently drill deepwater wells that can not be cost-effectively drilled with current technologies. The new fluids will be heavy liquid foams that have low-density at shallow dept to avoid formation breakdown and high density at drilling depth to control formation pressure. The goal of this project is to provide industry with formulations of new fluids for reducing casing programs and thus well construction cost in deepwater development. (2) Studying the effects of flue gas/CO{sub 2} huff n puff on incremental oil recovery in Louisiana oilfields bearing light oil. An artificial neural network (ANN) model will be developed and used to map recovery efficiencies for candidate reservoirs in Louisiana. (3) Arriving at a quantitative understanding for the three-dimensional controlled-source electromagnetic (CSEM) geophysical response of typical Gulf of Mexico hydrocarbon reservoirs. We will seek to make available tools for the qualitative, rapid interpretation of marine CSEM signatures, and tools for efficient, three-dimensional subsurface conductivity modeling.

    We will begin our treatment of summability calculus by analyzing what will be referred to, throughout this book, as simple finite sums. Even though the results of this chapter are particular cases of the more general results presented in later chapters, they are important to start with for a few reasons. First, this chapter serves as an excellent introduction to what summability calculus can markedly accomplish. Second, simple finite sums are encountered more often and, hence, they deserve special treatment. Third, the results presented in this chapter for simple finite sums will, themselves, be used as building blocks for deriving the most general results in subsequent chapters. Among others, we establish that fractional finite sums are well-defined mathematical objects and show how various identities related to the Euler constant as well as the Riemann zeta function can actually be derived in an elementary manner using fractional finite sums.

    Fischer's finite-size scaling describes the cross over from the singular behaviour of thermodynamic quantities at the critical point to the analytic behaviour of the finite system. Recent extensions of the method--transfer matrix technique, and the Hamiltonian formalism--are discussed in this paper. The method is presented, with equations deriving scaling function, critical temperature, and exponent v. As an application of the method, a 3-states Hamiltonian with Z 3 global symmetry is studied. Diagonalization of the Hamiltonian for finite chains allows one to estimate the critical exponents, and also to discover new phase transitions at lower temperatures. The critical points lambda, and indices v estimated for finite-scaling are given

    The circulation in the Gulf of Aden is inferred from three different data sets: h istorical sh ip drifts , hydrography , and satellite altimeter derived sea level (Topex/Poseidon, Jason and ERS) . The circulation in th is semi-enclosed basin is marked with strong seasonality with reversals in the direction of flows twice a year follow ing the reversal in mon soonal winds. During the win ter mon soon (November - February) there is an inflow from Arabian Sea; an extension of Arabian Coastal Current (ACC) . During sou thwest mon soon (June - August) the flow is generally towards east especially along the northern coast of Gulf of Aden. The geostrophic currents also show that the circulation in the gulf is embedded with mesoscale eddies. These westward propagating eddies appear to enter the Gulf of Aden from the western Arabian Sea in win ter. The relative contribu tion of mesoscale eddies to the circulation in the gulf were estimated using altimeter derived Sea level anomaly (SLA) for the years 1993 to 2003 . The effect of these mesoscale eddies extend over the entire water colu mn . The propagation speeds, of these eddies, estimated using weekly spaced altimeter derived SLA (2002 - 2003) is ~ 4 .0 - 5 .3 cm s . The sum of the speeds of second mode Ro ssby wave and the mean current (4.8 cm s ) matches with the propagation speeds of eddies estimated using SLA . Hence, second mode baroclin ic Rossby waves appear to be responsib le for the westward propagation of eddies in the Gulf of Aden. The presence of these eddies in the temperaturesalin ity climato logy confirms that they are no t transient features.

    The St. Lawrence maritime estuary is the subject of a major geological research project to determine the possible presence of natural gas. Exploration work conducted by the Geological Survey of Canada in 2003 and 2004 revealed the possible presence of hydrocarbons in the estuary's Quaternary geological formations. Several pockmarks resembling chimneys were found, through which small quantities of natural gas escape. Development of the resource was considered, given the basin's proximity to potential markets and transportation infrastructures. This first strategic environmental assessment (SEA) of the maritime estuary and the northwestern Gulf of St. Lawrence covered nearly 29,000 km{sup 2} of marine territory located east of the Saguenay-St. Lawrence Marine Park to the western tip of Anticosti Island. The objective was to better understand the biophysical, social, and economic components that characterize this basin and to draft recommendations concerning the conditions for oil and gas exploration and development. The SEA will be the first study of its kind supervised by the Quebec Ministere des ressources naturelles et de la Faune (MRNF). Exploration was carried out using seismic surveys and exploratory drilling. Development was divided into 3 phases, notably startup, production, and restoration of the production site to its original state. The assessment shows that this is a complex and fragile environment and that many communities depend on activities connected with tourism and commercial fishery. The SEA program will help to ensure all the necessary requirements are met for the sustainable development of the oil and gas resources in this marine environments. refs., tabs., figs.

    Full Text Available La forte croissance qu’ont connue les pays alpins dans les dernières décennies a surtout été fondée sur l’offre des activités du ski, avec comme conséquence, un massif développement immobilier, la multiplication d’infrastructures et l’extension des domaines. Aujourd’hui, le marché du ski semble arriver à saturation, la Convention alpine a mis un frein à la poursuite du développement des domaines skiables et on observe donc avec intérêt la diversification de l’offre soutenue par l’innovation. Après avoir rappelé les facteurs de changement en cours les plus significatifs dans le tourisme montagnard, l’article présente une grille interprétative de l’évolution des destinations touristiques alpines, identifiant les phases qui ont caractérisé son développement. Puis il propose une réflexion sur certaines conditions qui peuvent favoriser l’innovation dans le tourisme alpin, ainsi que sur les contradictions qui les accompagnent souvent. Dans la plupart des cas l’innovation est le résultat d’un processus qui a été lancé et qui s’est développé au sein de la communauté alpine, souvent favorisé et soutenu par des institutions nationales et internationales, et grâce auquel les difficultés structurelles qui ont déjà été abordées précédemment ont pu être surmontées avec succès.The spectacular increase in tourism in the Alps in recent decades has been founded mainly on the boom in skiing, resulting in both strong real estate development and an increasing array of infrastructures and ski runs. Today the ski market seems to have virtually reached saturation point and the winter sports sector needs to diversify its offer through innovation. After a review of the main factors of change in mountain tourism, the paper presents a grid for interpreting the life cycle of alpine destinations, identifying the phases that characterize their evolution.

Mais les fondements d'un modèle performant tels que l'étatisme et le nationalisme civique sont devenus empreints de faiblesses et d'insuffisances que l'utilisation du concept de gouvernance permet d'identifier. Le concept se définit comme étant « la coordination efficace de l'ensemble des activités d'une entité socio-économico-politique quand les ressources, le pouvoir et l'information sont vastement distribués ». Malgré l'inefficacité décrite, il est possible de repenser le modèle québécois de développement par la construction des communautés qui s'appuie sur la régionalité et la socialité.

    We discuss topics related to finite-dimensional calculus in the context of finite-dimensional quantum mechanics. The truncated Heisenberg-Weyl algebra is called a TAA algebra after Tekin, Aydin and Arik who formulated it in terms of orthofermions. It is shown how to use a matrix approach to implement analytic representations of the Heisenberg-Weyl algebra in univariate and multivariate settings. We provide examples for the univariate case. Krawtchouk polynomials are presented in detail, including a review of Krawtchouk polynomials that illustrates some curious properties of the Heisenberg-Weyl algebra, as well as presenting an approach to computing Krawtchouk expansions. From a mathematical perspective, we are providing indications as to how to implement infinite terms Rota's 'finite operator calculus'.

    This book discusses all three formalisms used in the study of finite temperature field theory, namely the imaginary time formalism, the closed time formalism and thermofield dynamics. Applications of the formalisms are worked out in detail. Gauge field theories and symmetry restoration at finite temperature are among the practical examples discussed in depth. The question of gauge dependence of the effective potential and the Nielsen identities are explained. The nonrestoration of some symmetries at high temperature (such as supersymmetry) and theories on nonsimply connected space-times are al

    2009-01-01

    Triangles and rectangles are the ubiquitous elements in finite element studies. Only these elements admit polynomial basis functions. Rational functions provide a basis for elements having any number of straight and curved sides. Numerical complexities initially associated with rational bases precluded extensive use. Recent analysis has reduced these difficulties and programs have been written to illustrate effectiveness. Although incorporation in major finite element software requires considerable effort, there are advantages in some applications which warrant implementation. An outline of the basic theory and of recent innovations is presented here. (authors)

    Full Text Available Tomato is a climacteric fruit, which is characterized by ripening-related increase of respiration and elevated ethylene synthesis. Ethylene is the key hormone in ripening process of climacteric fruits. The objective of this research is to study the expression of three ethylene synthesis genes: LeACO1, LeACS1A, LeACS2, and a housekeeping gene LeGAPDH in ripening tomato fruit. Specific primers have been designed to amplify complementary DNA fragment of LeGAPDH (143 bp, LeACO1 (240 bp, LeACS1A (169 bp, and LeACS2 (148 bp using polymerase chain reaction. Nucleotide BLAST results of the complementary DNA fragments show high similarity with LeGAPDH (NM_001247874.1, LeACO1 (NM_001247095.1, LeACS1A (NM_001246993.1, LeACS2 (NM_001247249.1, respectively. Expression study showed that LeACO1, LeACS1A, LeACS2, and LeGAPDH genes were expressed in ripening tomato fruit. Isolation methods, reference sequences, and primers used in this study can be used in future experiments to study expression of genes responsible for ethylene synthesis using quantitative polymerase chain reaction and to design better strategy for controlling fruit ripening in agroindustry.

    Antoine Laporte

    2013-06-01

    Full Text Available En Allemagne, en 1999, le Chancelier fédéral et son gouvernement ont quitté Bonn pour Berlin. Ce transfert du pouvoir est accompagné de celui d’une grande partie de l’appareil d’État et de la haute administration, et des fonctions qui leur sont traditionnellement attribuées comme la presse, les lobbys ou encore la diplomatie. Le déplacement du statut de capitale effective de l’Allemagne de Bonn à Berlin est le résultat des évolutions géopolitiques d’un pays ayant recouvré son unité et sa pleine et entière souveraineté. Installer le pouvoir exécutif et législatif à Berlin était une démarche hautement symbolique, visant à normaliser la position de l’ancienne capitale de la RDA et du IIIe Reich comme véritable centre politique de l’Allemagne. Or le déplacement des institutions fédérales n’est pas qu’un acte symbolique. Il entraîne également à l’échelle intra-urbaine des dynamiques très concrètes sur le tissu urbain et participe à la mise en place de nouvelles centralités dans la ville. En effet, le statut de capitale d’État prédestine l’agglomération à la coprésence de nombreuses fonctions urbaines spécifiques plus ou moins directement liées à l’exercice ou à la symbolique du pouvoir.

La chute brutale de la démographie depuis la seconde moitié du XVIe siècle a fait disparaître les 4 ayllu originels mais l’examen des archives permet d’observer un très vigoureux redressement démographique à partir des derniers 150 ans. Ce redressement démographique semble précipiter un nouvel éclatement de la communauté chipaya. El autor partiendo de las observaciones de Métraux sobre Chipaya, aporta sobre los ayllu que constituían el pueblo, basadas en una encuesta profunda y un plano detallado del pueblo: aparecen dos divisiones principales, dividiéndose éstas a su vez en cuatro ayllu. La caída brutal de la demografía desde la segunda mitad del siglo XVI ha hecho desaparecer los 4 ayllu primitivos pero el examen de los archivos permite observar un resurgimiento vigoroso a partir de los últimos 150 años. Este resurgimiento demográfico parece precipitar una nueva explosión de la comunidad chipaya.

    1986-01-01

    The consequences of the incorporation of finite temperature effects in fields theories are investigated. Particularly, we consider the sypersymmetric non-linear sigma model, calculating the effective potencial in the large N limit. Initially, we present the 1/N expantion formalism and, for the O(N) model of scalar field, we show the impossibility of spontaneous symmetry breaking. Next, we study the same model at finite temperature and in the presence of conserved charges (the O(N) symmetry's generator). We conclude that these conserved charges explicitly break the symmetry. We introduce a calculation method for the thermodynamic potential of the theory in the presence of chemical potentials. We present an introduction to Supersymmetry in the aim of describing some important concepts for the treatment at T>0. We show that Suppersymmetry is broken for any T>0, in opposition to what one expects, by the solution of the Hierachy Problem. (author) [pt

    Full Text Available This research work is devoted to the footprint analysis of a steel-belted radial tyre (185/65R14 under vertical static load using finite element method. Two models have been developed in which in the first model the tread patterns were replaced by simple ribs while the second model was consisted of details of the tread blocks. Linear elastic and hyper elastic (Arruda-Boyce material models were selected to describe the mechanical behavior of the reinforcing and rubbery parts, respectively. The above two finite element models of the tyre were analyzed under inflation pressure and vertical static loads. The second model (with detailed tread patterns was analyzed with and without friction effect between tread and contact surfaces. In every stage of the analysis, the results were compared with the experimental data to confirm the accuracy and applicability of the model. Results showed that neglecting the tread pattern design not only reduces the computational cost and effort but also the differences between computed deformations do not show significant changes. However, more complicated variables such as shape and area of the footprint zone and contact pressure are affected considerably by the finite element model selected for the tread blocks. In addition, inclusion of friction even in static state changes these variables significantly.

    1987-01-01

    In the Probabilistic Finite Element Method (PFEM), finite element methods have been efficiently combined with second-order perturbation techniques to provide an effective method for informing the designer of the range of response which is likely in a given problem. The designer must provide as input the statistical character of the input variables, such as yield strength, load magnitude, and Young's modulus, by specifying their mean values and their variances. The output then consists of the mean response and the variance in the response. Thus the designer is given a much broader picture of the predicted performance than with simply a single response curve. These methods are applicable to a wide class of problems, provided that the scale of randomness is not too large and the probabilistic density functions possess decaying tails. By incorporating the computational techniques we have developed in the past 3 years for efficiency, the probabilistic finite element methods are capable of handling large systems with many sources of uncertainties. Sample results for an elastic-plastic ten-bar structure and an elastic-plastic plane continuum with a circular hole subject to cyclic loadings with the yield stress on the random field are given.

    Objectives To determine how many veterans in a random sample of British veterans who served in the Gulf war believe they have “Gulf war syndrome,” to examine factors associated with the presence of this belief, and to compare the health status of those who believe they have Gulf war syndrome with those who do not. Design Questionnaire study asking British Gulf war veterans whether they believe they have Gulf war syndrome and about symptoms, fatigue, psychological distress, post-traumatic stress, physical functioning, and their perception of health. Participants 2961 respondents to questionnaires sent out to a random sample of 4250 Gulf war veterans (69.7%). Main outcome measure The proportion of veterans who believe they have Gulf war syndrome. Results Overall, 17.3% (95% confidence interval 15.9 to 18.7) of the respondents believed they had Gulf war syndrome. The belief was associated with the veteran having poor health, not serving in the army when responding to the questionnaire, and having received a high number of vaccinations before deployment to the Gulf. The strongest association was knowing another person who also thought they had Gulf war syndrome. Conclusions Substantial numbers of British Gulf war veterans believe they have Gulf war syndrome, which is associated with psychological distress, a high number of symptoms, and some reduction in activity levels. A combination of biological, psychological, and sociological factors are associated with the belief, and these factors should be addressed in clinical practice. What is already known on this topicThe term Gulf war syndrome has been used to describe illnesses and symptoms experienced by veterans of the 1991 Gulf warConcerns exist over the validity of Gulf war syndrome as a unique entityWhat this study adds17% of Gulf war veterans believe they have Gulf war syndromeHolding the belief is associated with worse health outcomesKnowing someone else who believes they have Gulf war syndrome and receiving

  14. Gulf war depleted uranium risks.

    2008-01-01

    US and British forces used depleted uranium (DU) in armor-piercing rounds to disable enemy tanks during the Gulf and Balkan Wars. Uranium particulate is generated by DU shell impact and particulate entrained in air may be inhaled or ingested by troops and nearby civilian populations. As uranium is slightly radioactive and chemically toxic, a number of critics have asserted that DU exposure has resulted in a variety of adverse health effects for exposed veterans and nearby civilian populations. The study described in this paper used mathematical modeling to estimate health risks from exposure to DU during the 1991 Gulf War for both US troops and nearby Iraqi civilians. The analysis found that the risks of DU-induced leukemia or birth defects are far too small to result in an observable increase in these health effects among exposed veterans or Iraqi civilians. The analysis indicated that only a few ( approximately 5) US veterans in vehicles accidentally targeted by US tanks received significant exposure levels, resulting in about a 1.4% lifetime risk of DU radiation-induced fatal cancer (compared with about a 24% risk of a fatal cancer from all other causes). These veterans may have also experienced temporary kidney damage. Iraqi children playing for 500 h in DU-destroyed vehicles are predicted to incur a cancer risk of about 0.4%. In vitro and animal tests suggest the possibility of chemically induced health effects from DU internalization, such as immune system impairment. Further study is needed to determine the applicability of these findings for Gulf War exposure to DU. Veterans and civilians who did not occupy DU-contaminated vehicles are unlikely to have internalized quantities of DU significantly in excess of normal internalization of natural uranium from the environment.

    This paper gives an environmental damage report for the Kuwait-Persian Gulf area that has been affected by the Gulf War oil well fires and the release of oil into the sea. The report was prepared by members of an ENEA (Italian Commission for New Technologies, Energy and the Environment)/Friends of the Earth scientific mission whose aim was to assess the damage to terrestrial and aquatic ecosystems and to develop short and long terms programs of damage containment and environmental restoration. With regard to shore-line clean-up operations, the mission noted the scarce use of manpower, 500 versus 11,000 for the Exxon Valdez spill. Seventy-five per cent of the surface of Kuwait has been covered with a fine spray of petroleum and ashes borne by turbulent winds.

  8. Alaska, Gulf spills share similarities

    International Nuclear Information System (INIS)

    Usher, D.

    1991-01-01

    The accidental Exxon Valdez oil spill in Alaska and the deliberate dumping of crude oil into the Persian Gulf as a tactic of war contain both glaring differences and surprising similarities. Public reaction and public response was much greater to the Exxon Valdez spill in pristine Prince William Sound than to the war-related tragedy in the Persian Gulf. More than 12,000 workers helped in the Alaskan cleanup; only 350 have been involved in Kuwait. But in both instances, environmental damages appear to be less than anticipated. Natures highly effective self-cleansing action is primarily responsible for minimizing the damages. One positive action growing out of the two incidents is increased international cooperation and participation in oil-spill clean-up efforts. In 1990, in the aftermath of the Exxon Valdez spill, 94 nations signed an international accord on cooperation in future spills. The spills can be historic environmental landmarks leading to creation of more sophisticated response systems worldwide

Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

  16. Thermohaline circulation in the Gulf of California

    Science.gov (United States)

    Bray, N. A.

    1988-05-01

    The Gulf of California, a narrow, semienclosed sea, is the only evaporative basin of the Pacific Ocean. As a result of evaporative forcing, salinities in the gulf are 1 to 2 ‰ higher than in the adjacent Pacific at the same latitude. This paper examines the thermohaline structure of the gulf and the means by which thermohaline exchange between the Pacific and the gulf occurs, over time scales of months to years. In addition to evaporative forcing, air-sea heat fluxes and momentum fluxes are important to thermohaline circulation in the gulf. From observations presented here, it appears that the gulf gains heat from the atmosphere on an annual average, unlike the Mediterranean and Red seas, which have comparable evaporative forcing. As a result, outflow from the gulf tends to be less dense than inflow from the Pacific. Winds over the gulf change direction with season, blowing northward in summer and southward in winter. This same seasonal pattern appears in near-surface transports averaged across the gulf. The thermohaline circulation, then, consists of outflow mostly between about 50 m and 250 m, inflow mostly between 250 m and 500 m, and a surface layer in which the direction of transport changes with seasonal changes in the large-scale winds. Using hydrographic observations from a section across the central gulf, total transport in or out of the northern gulf is estimated to be 0.9 Sv, heat gain from the atmosphere is estimated to be 20 to 50 W m-2, and evaporation is estimated to be 0.95 m yr-1. These estimates are annual averages, based on cruises from several years. Seasonal variations in thermohaline structure in the gulf are also examined and found to dominate the variance in temperature and density in the top 500 m of the water column. Salinity has little seasonal variability but does exhibit more horizontal variablility than temperature or density. Major year-to-year variations in thermohaline structure may be attributable to El Niño-Southern Oscillation

    This paper reports that the extent of damage caused by Hurricane Andrew to Gulf of Mexico oil and gas installations continues coming into focus. A preliminary tally by Minerals Management Service offers a reasonably complete summary of gulf production and pipeline systems damage detectable at the surface. MMS requires Outer Continental Shelf operators to inspect for underwater damage all platforms, pipelines, risers, and other structures within an 85 mile corridor along the path of Andrew's eye as it churned through the gulf. OCS operators have until Oct. 16 to submit plans for the Level II surveys

    Oil projects in the Gulf of Mexico have suffered from the crash in oil prices in the mid-1980s, however as these projects tend to be long-term and therefore less sensitive to current oil prices, many are continuing to be funded. It is now believed by deepwater exploration operators that the Gulf of Mexico may be one of the world's most promising sources of new reserves. This article analyses the likely future exploration of deepwater reserves by major companies such as Shell, noted for its capital intensive and technologically innovative activity in the Gulf, as well as the newer, smaller independent operators.

  7. Finiteness of corner vortices

    Science.gov (United States)

    Kalita, Jiten C.; Biswas, Sougata; Panda, Swapnendu

    2018-04-01

    Till date, the sequence of vortices present in the solid corners of steady internal viscous incompressible flows was thought to be infinite. However, the already existing and most recent geometric theories on incompressible viscous flows that express vortical structures in terms of critical points in bounded domains indicate a strong opposition to this notion of infiniteness. In this study, we endeavor to bridge the gap between the two opposing stream of thoughts by diagnosing the assumptions of the existing theorems on such vortices. We provide our own set of proofs for establishing the finiteness of the sequence of corner vortices by making use of the continuum hypothesis and Kolmogorov scale, which guarantee a nonzero scale for the smallest vortex structure possible in incompressible viscous flows. We point out that the notion of infiniteness resulting from discrete self-similarity of the vortex structures is not physically feasible. Making use of some elementary concepts of mathematical analysis and our own construction of diametric disks, we conclude that the sequence of corner vortices is finite.

    Full Text Available RESUMEN Cuando Le Corbusier ya había pasado de los cuarenta años se enfrentó a dos concursos internacionales: el Palacio de las Naciones en Ginebra (1926–31 y el Palacio de los Soviets en Moscú (1931–32 con los que intentaba acceder a grandes encargos de estado con mayor escala urbana en los que poner a prueba su ideario moderno sobre arquitectura y urbanismo. En ambos casos estuvo entre los vencedores pero por conveniencia e indecisión, los poderes políticos optaron por soluciones academicistas. Al conocer las decisiones definitivas, Le Corbusier y todos sus contactos del Movimiento Moderno orquestaron diversas polémicas ante los medios de comunicación y los gobernantes por entender que el progreso se veía lastrado por el triunfo de propuestas reaccionarias. Mediante el estudio de la correspondencia con personas particulares como Moser, Giedion, Colly o Stonorov, conservada en la Fundación Le Corbusier, se analizan las relaciones y el tono ideológico en torno a aquellas protestas. En esos textos quedan reflejados los principales rasgos que caracterizan la modernidad como su internacionalización, la seguridad en la propia misión, la defensa de lo nuevo o el método dialéctico. SUMMARY When Le Corbusier had already passed the age of forty he confronted two international competitions: the Palais des Nations in Geneva (1926–1931 and the Palace of the Soviets in Moscow (1931–32, with which he attempted to access large state commissions, with greater urban scale, in which to test his ideas about modern architecture and urbanism. In both cases he was among the winners, but through convenience and indecision the political powers opted for solutions from academicians. Upon knowing the final decisions, Le Corbusier and all his contacts in the Modern Movement orchestrated several controversies with the media, and the people in power, to convey that progress seemed burdened by the triumph of reactionary proposals.

    Que nous dit vraiment la science sur la nature de l'univers, sur son origine et son avenir ? Par quel mystère le langage mathématique, pure création de l'esprit humain, se révèle-t-il aussi performant pour nous décrire les phénomènes physiques, de l'infiniment petit à l'infiniment grand ? S'il existe un ordre du monde, ce que nous en disent la physique quantique et la théorie de la relativité est-il compatible avec ce qu'enseigne le bouddhisme ?

  8. The Determining Finite Automata Process

    Directory of Open Access Journals (Sweden)

    M. S. Vinogradova

    2017-01-01

    Full Text Available The theory of formal languages widely uses finite state automata both in implementation of automata-based approach to programming, and in synthesis of logical control algorithms.To ensure unambiguous operation of the algorithms, the synthesized finite state automata must be deterministic. Within the approach to the synthesis of the mobile robot controls, for example, based on the theory of formal languages, there are problems concerning the construction of various finite automata, but such finite automata, as a rule, will not be deterministic. The algorithm of determinization can be applied to the finite automata, as specified, in various ways. The basic ideas of the algorithm of determinization can be most simply explained using the representations of a finite automaton in the form of a weighted directed graph.The paper deals with finite automata represented as weighted directed graphs, and discusses in detail the procedure for determining the finite automata represented in this way. Gives a detailed description of the algorithm for determining finite automata. A large number of examples illustrate a capability of the determinization algorithm.

    The latest MoEDAL experiment at LHC to detect the electroweak monopole makes the theoretical prediction of the monopole mass an urgent issue. We discuss three different ways to estimate the mass of the electroweak monopole. We first present the dimensional and scaling arguments which indicate the monopole mass to be around 4 to 10 TeV. To justify this we construct finite energy analytic dyon solutions which could be viewed as the regularized Cho-Maison dyon, modifying the coupling strength at short distance. Our result demonstrates that a genuine electroweak monopole whose mass scale is much smaller than the grand unification scale can exist, which can actually be detected at the present LHC. (orig.)

    Liu, W. K.; Belytschko, T.; Lua, Y. J.

    1991-05-01

    The Probabilistic Fracture Mechanics (PFM) is a promising method for estimating the fatigue life and inspection cycles for mechanical and structural components. The Probability Finite Element Method (PFEM), which is based on second moment analysis, has proved to be a promising, practical approach to handle problems with uncertainties. As the PFEM provides a powerful computational tool to determine first and second moment of random parameters, the second moment reliability method can be easily combined with PFEM to obtain measures of the reliability of the structural system. The method is also being applied to fatigue crack growth. Uncertainties in the material properties of advanced materials such as polycrystalline alloys, ceramics, and composites are commonly observed from experimental tests. This is mainly attributed to intrinsic microcracks, which are randomly distributed as a result of the applied load and the residual stress.

    International Nuclear Information System (INIS)

    Tonks, M.R.; Williamson, R.; Masson, R.

    2015-01-01

    The Finite Element Method (FEM) is a numerical technique for finding approximate solutions to boundary value problems. While FEM is commonly used to solve solid mechanics equations, it can be applied to a large range of BVPs from many different fields. FEM has been used for reactor fuels modelling for many years. It is most often used for fuel performance modelling at the pellet and pin scale, however, it has also been used to investigate properties of the fuel material, such as thermal conductivity and fission gas release. Recently, the United Stated Department Nuclear Energy Advanced Modelling and Simulation Program has begun using FEM as the basis of the MOOSE-BISON-MARMOT Project that is developing a multi-dimensional, multi-physics fuel performance capability that is massively parallel and will use multi-scale material models to provide a truly predictive modelling capability.

    2012-01-01

    We present an overview of the theory of finite groups, with regard to their application as flavour symmetries in particle physics. In a general part, we discuss useful theorems concerning group structure, conjugacy classes, representations and character tables. In a specialized part, we attempt to give a fairly comprehensive review of finite subgroups of SO(3) and SU(3), in which we apply and illustrate the general theory. Moreover, we also provide a concise description of the symmetric and alternating groups and comment on the relationship between finite subgroups of U(3) and finite subgroups of SU(3). Although in this review we give a detailed description of a wide range of finite groups, the main focus is on the methods which allow the exploration of their different aspects. (topical review)

  2. On finite quantum field theories

    International Nuclear Information System (INIS)

    1984-01-01

    The properties that make massless versions of N = 4 super Yang-Mills theory and a class of N = 2 supersymmetric theories finite are: (I) a universal coupling for the gauge and matter interactions, (II) anomaly-free representations to which the bosonic and fermionic matter belong, and (III) no charge renormalisation, i.e. β(g) = 0. It was conjectured that field theories constructed out of N = 1 matter multiplets are also finite if they too share the above properties. Explicit calculations have verified these theories to be finite up to two loops. The implications of the finiteness conditions for N = 1 finite field theories with SU(M) gauge symmetry are discussed.

  3. Massively Parallel Finite Element Programming

    KAUST Repository

    2010-01-01

    Today\\'s large finite element simulations require parallel algorithms to scale on clusters with thousands or tens of thousands of processor cores. We present data structures and algorithms to take advantage of the power of high performance computers in generic finite element codes. Existing generic finite element libraries often restrict the parallelization to parallel linear algebra routines. This is a limiting factor when solving on more than a few hundreds of cores. We describe routines for distributed storage of all major components coupled with efficient, scalable algorithms. We give an overview of our effort to enable the modern and generic finite element library deal.II to take advantage of the power of large clusters. In particular, we describe the construction of a distributed mesh and develop algorithms to fully parallelize the finite element calculation. Numerical results demonstrate good scalability. © 2010 Springer-Verlag.

Existing generic finite element libraries often restrict the parallelization to parallel linear algebra routines. This is a limiting factor when solving on more than a few hundreds of cores. We describe routines for distributed storage of all major components coupled with efficient, scalable algorithms. We give an overview of our effort to enable the modern and generic finite element library deal.II to take advantage of the power of large clusters. In particular, we describe the construction of a distributed mesh and develop algorithms to fully parallelize the finite element calculation. Numerical results demonstrate good scalability. © 2010 Springer-Verlag.

  8. Finite discrete field theory

    International Nuclear Information System (INIS)

    Souza, Manoelito M. de

    1997-01-01

    We discuss the physical meaning and the geometric interpretation of implementation in classical field theories. The origin of infinities and other inconsistencies in field theories is traced to fields defined with support on the light cone; a finite and consistent field theory requires a light-cone generator as the field support. Then, we introduce a classical field theory with support on the light cone generators. It results on a description of discrete (point-like) interactions in terms of localized particle-like fields. We find the propagators of these particle-like fields and discuss their physical meaning, properties and consequences. They are conformally invariant, singularity-free, and describing a manifestly covariant (1 + 1)-dimensional dynamics in a (3 = 1) spacetime. Remarkably this conformal symmetry remains even for the propagation of a massive field in four spacetime dimensions. We apply this formalism to Classical electrodynamics and to the General Relativity Theory. The standard formalism with its distributed fields is retrieved in terms of spacetime average of the discrete field. Singularities are the by-products of the averaging process. This new formalism enlighten the meaning and the problem of field theory, and may allow a softer transition to a quantum theory. (author)

  9. Mimetic finite difference method

    Lipnikov, Konstantin; Manzini, Gianmarco; Shashkov, Mikhail

    2014-01-01

    The mimetic finite difference (MFD) method mimics fundamental properties of mathematical and physical systems including conservation laws, symmetry and positivity of solutions, duality and self-adjointness of differential operators, and exact mathematical identities of the vector and tensor calculus. This article is the first comprehensive review of the 50-year long history of the mimetic methodology and describes in a systematic way the major mimetic ideas and their relevance to academic and real-life problems. The supporting applications include diffusion, electromagnetics, fluid flow, and Lagrangian hydrodynamics problems. The article provides enough details to build various discrete operators on unstructured polygonal and polyhedral meshes and summarizes the major convergence results for the mimetic approximations. Most of these theoretical results, which are presented here as lemmas, propositions and theorems, are either original or an extension of existing results to a more general formulation using polyhedral meshes. Finally, flexibility and extensibility of the mimetic methodology are shown by deriving higher-order approximations, enforcing discrete maximum principles for diffusion problems, and ensuring the numerical stability for saddle-point systems.

  10. Numerical modeling of persian gulf salinity variations due to tidal effects

    International Nuclear Information System (INIS)

    Sabbagh Yazdi, S.R.

    2004-01-01

    Numerical modeling of salinity changes in marine environment of Persian Gulf is investigated in this paper. Computer simulation of the problem is performed by the solution of a convection-diffusion equation for salinity concentration coupled with the hydrodynamic equations. The hydrodynamic equations consist of shallow water equations of continuity and motion in horizontal plane. The effects of rain and evaporations are considered in the continuity equation and the effects of bed slope and friction, as well as Coriolis effects are considered in two equations of motion. The cell vertex finite volume method is applied for solving the governing equations on triangular unstructured meshes. Using unstructured meshes provides great flexibility for modeling the flow problems in arbitrary and complex geo metrics, such as Persia Gulf domain. The results of evaporation and Coriolis effects, as well as imposing river and tidal boundary conditions to the hydrodynamic model of Persian Gulf (considering variable topology rough bed) are compared with predictions of Admiralty Tide Table, Which are obtained from the harmonic analysis. The performance of the developed computer model is demonstrated by simulation of salinity changes due to inflow effects and diffusion effects as well as computed currents

  15. Post Gulf War oil supply

    International Nuclear Information System (INIS)

    1991-01-01

    One of the spin-offs from the Gulf War will be a change in the old order within OPEC. With Iraq and Kuwait production stopped because of the war, output from OPEC countries is around 23.5 million barrels per day compared with about 20 million last August before the Iraqi invasion of Kuwait. It is reported that there are some 225 to 235 million barrels of oil in inventory, worldwide, above normal levels. As seen in the accompanying graph, oil prices have drifted back to about the same level as in March 1990 from the wartime high of nearly $40/bbl. Before the invasion, Saudi Arabia's quota was 5.4 million bbls per day. Since then, Saudi has pumped at 7.7 to 7.9 bbls per day with plans to reactivate shut-in wells which will bring production capability to 10 million bbls per day. Other OPEC countries are at maximum capacity and some, Venezuela, for example, are also in the process of expanding production. This article discusses the effect of the war on the future oil supply, other countries' response to Iraq oil production, and prediction of possible oil price response

    A relativistic quantum field theory at finite temperature T=β -1 is equivalent to the same field theory at zero temperature but with one spatial dimension of finite length β. This equivalence is discussed for scalars, for fermions, and for gauge theories. The relationship is checked for free field theory. The translation of correlation functions between the two formulations is described with special emphasis on the nonlocal order parameters of gauge theories. Possible applications are mentioned.

    We have used the real time formalism to compute the one-loop finite temperature corrections to the photon self energies in spinor and scalar QED. We show that, for a real photon, only the transverse components develop the temperature-dependent masses, while, for an external static electromagnetic field applied to the finite temperature system, only the static electric field is screened by thermal fluctuations. After showing how to compute systematically the imaginary parts of the finite temperature Green functions, we have attempted to give a microscopic interpretation of the imaginary parts of the self energies.

    We study the canonical transformations of the quantum mechanics on a finite phase space. For simplicity we assume that the configuration variable takes an odd prime number 4 K±1 of distinct values. We show that the canonical group is unitarily implemented. It admits a maximal abelian subgroup of order 4 K, commuting with the finite Fourier transform F, a finite analogue of the harmonic oscillator group. This provides a natural construction of F 1/K and of an orthogonal basis of eigenstates of F [fr

  9. Sur la modélisation des supraconducteurs : le ``modèle de l'état critique'' de Bean, en trois dimensions

    Science.gov (United States)

    Bossavit, A.

    1993-03-01

    Macroscopic modelling of superconductors demands a substitution of some nonlinear behavior law for Ohm's law. For this, a version of Bean's “critical state” model, derived from the setting of a convex functional of the current density field, valid in dimension 3 without any previous assumption about the direction of currents, is proposed. It is shown how two standard three-dimensional finite element methods (“h-formulation” and “e-formulation”), once fitted with this model, can deal with situations were superconductors are present. La modélisation macroscopique des supraconducteurs suppose le remplacement de la loi d'Ohm par une loi de comportement non linéaire adéquate. On présente à cet effet une version du “modèle de Bean”, ou modèle de l'état critique, basée sur la construction d'une certaine fonctionnelle convexe du champ des densités de courant, qui est valable en dimension 3 sans hypothèses préalables sur la direction des courants. On montre comment adapter deux méthodes standards de calcul de courants de Foucault par élérnents finis en trois dimensions (“en h” et “en e”) à la présence de supraconducteurs, en incorporant ce modèle.

Le sperme est prélevé toutes les semaines à partir du début de février, et pendant près de 2 mois. La quantité de sperme recueillie est très faible et présente de fortes variations individuelles ; elle augmente progressivement jusqu'à la 5me semaine et décroit ensuite. La quantité moyenne de sperme récoltée par mâle est de l'ordre de 0,7 ml/semaine et varie considérablement d'un mâle à l'autre (0.07 à 1,5 ml. La concentration du sperme en spermatozoïdes varie entre 18 et 25 milliards par ml ( X = 21,5 109 + 2,11. La quantité de spermatozoïdes récoltée par semaine est de 28,5 106 + 26,4/kg de poids corporel. La qualité du sperme appréciée par l'intensité et la durée de motilité suit une évolution similaire à celle de la quantité de sperme récoltée avec des valeurs maximales à 4 semaines et minimales en début et fin de période de prélèvement. Les premières ovulations détectées sur des femelles stockées dans les mêmes conditions que les mâles ont été observées à la 6me semaine de prélèvements alors que les performances de spermiation avaient déjà fortement déclinées. Il est vraisemblable que les conditions expérimentales particulièrement traumatisantes pour les mâles ont affecté prématurément la spermiation, amplifiant ainsi le décalage fréquemment observé entre les périodes de spermiation et d'ovulation.

    The wealth of indigenous oil resources has largely determined the economic and energy use patterns in the member countries of the Gulf Cooperation Council (GCC). Sizable profits accrued from the inflation of world oil prices spurred tremendous economic growth across the Gulf during the 1970s. The GCC nations channeled this oil wealth into the rapid development of infrastructure and the creation of super-welfare states. Today, these highly affluent societies enjoy benefits ranging from free medical care, schooling and housing to subsidized electricity and gasoline supplies. The combination of great personal prosperity, abundant petroleum resources and highly subsidized energy prices has led to excessive energy use in the Gulf nations. These countries consume among the highest amounts of energy per capita in the world. Correspondingly, these nations generate among the highest levels of energy-related carbon per capita

    The deepwater Gulf of Mexico, an emerging basin with 20 BBOE resource potential, was discussed. Technologies are advancing and development options are increasing within the Gulf of Mexico deepwater environment. Deepwater offers significant rate potentials leading to strong cash flows. The projected steep rate of resources captured in the next five years show that there is a short window of opportunity to establish a business position. The major production variables are development costs and cycle time. There is a definite market for Gulf of Mexico products because U.S. energy demand is expected to outstrip U.S. supply. Present infrastructure is capable of moving large volumes of gas into major U.S. markets, but with the large number of projects currently underway, especially in the United States, supply could exceed capacity. 1 tab., 16 figs

    A summary review of deepwater Gulf of Mexico (GOM) oil production was presented for the years 1989 to 1998. Trends and prospects in deepwater GOM production and leasing were assessed. Promises and forecasts made in the early 1990s were compared with what actually happened since then. Forecasts in the early 1990s promised deeper, faster and cheaper developments in the deepwater Gulf. Results of the comparison showed that the prognosticators were correct on all three counts. Regarding the future of the Gulf, one can be justified in being optimistic in so far as more experience, robust economics, more and cheaper rigs can be taken as reliable indicators of optimism. In contrast, there are certain negatives to consider, such as low commodity prices, budget constraints, lease expirations, technical challenges and increased competition. . 12 figs

    The Gulf Coast Clean Energy Application Center was initiated to significantly improve market and regulatory conditions for the implementation of combined heat and power technologies. The GC CEAC was responsible for the development of CHP in Texas, Louisiana and Oklahoma. Through this program we employed a variety of outreach and education techniques, developed and deployed assessment tools and conducted market assessments. These efforts resulted in the growth of the combined heat and power market in the Gulf Coast region with a realization of more efficient energy generation, reduced emissions and a more resilient infrastructure. Specific t research, we did not formally investigate any techniques with any formal research design or methodology.

    In the early 2003, American troops toppled the regime of Saddam Hussein in Iraq. Few weeks later, President Bush introduced his vision to solve the Arab-Israeli conflict in what is known as the 'road map'. These interrelated developments confirm the connection between the two Middle-Eastern sub-systems--the Persian Gulf and the Levant and provide an opportunity to achieve a comprehensive peace. Regional economic cooperation is seen as the sine qua non of a durable peace. This study examines the potential for an energy partnership between the Persian Gulf hydrocarbon producers and Israel

    We study the first-order transition in the model of a simple perceptron with continuous weights and large, bit finite value of the inputs. Making the analogy with the usual finite-size physical systems, we calculate the shift and the rounding exponents near the transition point. In the case of a general perceptron with larger variety of inputs, the analysis only gives bounds for the exponents.

    This set of images from the Multi-angle Imaging SpectroRadiometer highlights coastal areas of four states along the Gulf of Mexico: Louisiana, Mississippi, Alabama and part of the Florida panhandle. The images were acquired on October 15, 2001 (Terra orbit 9718)and represent an area of 345 kilometers x 315 kilometers.The two smaller images on the right are (top) a natural color view comprised of red, green, and blue band data from MISR's nadir(vertical-viewing) camera, and (bottom) a false-color view comprised of near-infrared, red, and blue band data from the same camera. The predominantly red color of the false-color image is due to the presence of vegetation, which is bright at near-infrared wavelengths. Cities appear as grey patches, with New Orleans visible at the southern edge of Lake Pontchartrain, along the left-hand side of the images. The Lake Pontchartrain Bridge runs approximately north-south across the middle of the lake. The distinctive shape of the Mississippi River Delta can be seen to the southeast of New Orleans. Other coastal cities are visible east of the Mississippi, including Biloxi, Mobile and Pensacola.The large image is similar to the true-color nadir view, except that red band data from the 60-degree backward-looking camera has been substituted into the red channel; the blue and green data from the nadir camera have been preserved. In this visualization, green hues appear somewhat subdued, and a number of areas with a reddish color are present, particularly near the mouths of the Mississippi, Pascagoula, Mobile-Tensaw, and Escambia Rivers. Here, the red color is highlighting differences in surface texture. This combination of angular and spectral information differentiates areas with aquatic vegetation associated with poorly drained bottom lands, marshes, and/or estuaries from the surrounding surface vegetation. These wetland regions are not as well differentiated in the conventional nadir views.Variations in ocean color are apparent in

  20. Influence of Subtropical Jetstream on Arabian Gulf Precipitation

    Science.gov (United States)

    2017-12-01

    The Arabian Gulf and surrounding regions are predominantly arid. However, this region hosts a large population due to the intense economic activity that is centered on the exploration of natural resources in and around the Arabian Gulf. Thus, few precipitation events that occur during boreal winter are important for society and ecology of this region. The mechanisms of winter precipitation over the Gulf are not well understood, partly due to a lack of long term meteorological observation. Here we explore the dynamics of Arabian Gulf winter precipitation events using available observations and a high resolution atmospheric model simulation. Our analyses show that the northern Gulf receives about six times more precipitation than the southern Gulf. Often, the southern Gulf precipitation forms as a result of downstream development of northern Gulf disturbance. The southward movement of northern Gulf disturbances is influenced by the location of subtropical jet. The probability of a northern Gulf precipitating weather system to move south is higher when the subtropical jet is located equatorward of 30°N. The equatorward position of jet favors the penetration of mid-latitude weather systems over the Arabian Peninsula, which in turn pushes the Arabian anticyclone eastward and triggers moisture transport from the Arabian Sea that is essential for southern Gulf precipitation events.

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Le concept de documentation future recèle un paradoxe : le mot documenter renvoie à des traces relevées dans un passé factuel, tandis que le futur ne peut, par définition, être qu’incertain, que l’objet de fantasmes, de projections. L’analyse suivante questionne ce paradoxe à travers l’analyse d’un motif cinématographique : un homme et une femme face à une tranche de séquoia, représentation symbolique du temps. Ce motif apparait dans trois oeuvres majeures du cinéma : Vertigo, d’Alfred Hitchcock, La Jetée de Chris Marker, et l’Armée des douze singes, de Terry Gilliam. La répétition de ce motif est mise en rapport avec l’ouvrage de Pierre Bayard, Le plagiat par anticipation, afin de l’envisager sous l’angle du paradoxe temporel, plutôt que sous le régime de la chronologie historique. Cette analyse prend pour point de départ une oeuvre intitulée Vozes Fantasmas, qui sur le principe de la documentation future propose d’écouter des murmures de spectateurs visitant une exposition qui n’a pas eu lieu. RESUMO O conceito de documentação do futuro evoca um paradoxo: o verbo documentar refere-se a traços ou rastros preservados de um passado factual, enquanto o futuro por definição é algo incerto, objeto de especulações, fantasias e projeções. Nossa reflexão questiona este paradoxo a partir da análise de uma cena cinematográfica: um homem e uma mulher em frente de um corte de sequoia, que é a representação simbólica do tempo. Esta cena aprece em três grandes obras do cinema: Vertigo (Um corpo que cai de Alfred Hitchcock, La Jetée de Chris Marker, e Os Doze Macacos de Terry Gilliam. A repetição desta cena é abordada em relação à obra de Pierre Bayard, Plágio por antecipação, a fim de considerá-la em termos de paradoxo temporal, e não como uma cronologia histórica.

    Full Text Available Taxonomic composition of fish larvae was analysed from 464 plankton samples obtained during 10 oceanographic surveys in the Gulf of California between 1984 and 1988. We identified 283 taxa: 173 species, 57 genera, and 53 families. Tropical and subtropical species predominated except during the winter, when temperate-subarctic species were dominant. The most abundant species were the mesopelagic Benthosema panamense, Triphoturus mexicanus and Vinciguerria lucetia, but the coastal pelagic species Engraulis mordax, Opisthonema spp., Sardinops caeruleus and Scomber japonicus were also prominent. The taxonomic composition of the ichthyoplankton shows the seasonality of the Gulf as well as environmental changes that occurred between the 1984-1987 warm period and the 1956-1957 cool period previously reported. The presence of E. mordax larvae as one of the most abundant species in the Gulf provides evidence of the reproduction of this species two years before the development of the northern anchovy fishery and the decline of the sardine fishery in the Gulf of California.

  3. Energy partnership: China and the Gulf states

    International Nuclear Information System (INIS)

    Bahgat, G.

    2005-01-01

    One of the most significant developments in the global energy market in the last several years has been China's skyrocketing demand for energy. In 1993, China became a net oil importer for the first time in its history and in 2003 replaced Japan as the world's second-largest oil importer (after the United States). The country needs more energy to maintain its spectacular economic performance. This study examines China's attempts to satisfy its growing needs for oil and natural gas by increasing imports from Russia and Central Asia/Caspian Sea region. The analysis suggests that despite growing cooperation between the two sides, the Gulf region is likely to satisfy most of China's hydrocarbons needs. Energy partnership between China and the Gulf has already started and is likely to be consolidated over the next few decades. The study also argues that this growing partnership between China and the Gulf should not be seen as a threat to any third party. The global energy market is well-integrated. Energy policy should not be seen in zero-sum terms. A China-Gulf partnership will benefit both sides and contribute to the stability of global energy markets. (author)

    International Nuclear Information System (INIS)

    Lucha, W.; Neufeld, H.

    1986-01-01

    We study the consequences of finiteness for a general renormalizable quantum field theory by analysing the finiteness conditions resulting from the requirement of absence of divergent contributions to the renormalizations of the parameters of an arbitrary gauge theory. In all cases considered, the well-known two-loop finite supersymmetric theories prove to be the unique solution of the finiteness criterion. (Author)

  7. Toward finite quantum field theories

    International Nuclear Information System (INIS)

    Rajpoot, S.; Taylor, J.G.

    1986-01-01

    The properties that make the N=4 super Yang-Mills theory free from ultraviolet divergences are (i) a universal coupling for gauge and matter interactions, (ii) anomaly-free representations, (iii) no charge renormalization, and (iv) if masses are explicitly introduced into the theory, then these are required to satisfy the mass-squared supertrace sum rule Σsub(s=0.1/2)(-1)sup(2s+1)(2s+1)M 2 sub(s)=O. Finite N=2 theories are found to satisfy the above criteria. The missing member in this class of field theories are finite field theories consisting of N=1 superfields. These theories are discussed in the light of the above finiteness properties. In particular, the representations of all simple classical groups satisfying the anomaly-free and no-charge renormalization conditions for finite N=1 field theories are discussed. A consequence of these restrictions on the allowed representations is that an N=1 finite SU(5)-based model of strong and electroweak interactions can contain at most five conventional families of quarks and leptons, a constraint almost compatible with the one deduced from cosmological arguments.

  8. On characters of finite groups

    CERN Document Server

    Broué, Michel

    2017-01-01

    This book explores the classical and beautiful character theory of finite groups. It does it by using some rudiments of the language of categories. Originally emerging from two courses offered at Peking University (PKU), primarily for third-year students, it is now better suited for graduate courses, and provides broader coverage than books that focus almost exclusively on groups. The book presents the basic tools, notions and theorems of character theory (including a new treatment of the control of fusion and isometries), and introduces readers to the categorical language at several levels. It includes and proves the major results on characteristic zero representations without any assumptions about the base field. The book includes a dedicated chapter on graded representations and applications of polynomial invariants of finite groups, and its closing chapter addresses the more recent notion of the Drinfeld double of a finite group and the corresponding representation of GL_2(Z).

    CERN Document Server

    Vourdas, Apostolos

    2017-01-01

    This monograph provides an introduction to finite quantum systems, a field at the interface between quantum information and number theory, with applications in quantum computation and condensed matter physics. The first major part of this monograph studies the so-called `qubits' and `qudits', systems with periodic finite lattice as position space. It also discusses the so-called mutually unbiased bases, which have applications in quantum information and quantum cryptography. Quantum logic and its applications to quantum gates is also studied. The second part studies finite quantum systems, where the position takes values in a Galois field. This combines quantum mechanics with Galois theory. The third part extends the discussion to quantum systems with variables in profinite groups, considering the limit where the dimension of the system becomes very large. It uses the concepts of inverse and direct limit and studies quantum mechanics on p-adic numbers. Applications of the formalism include quantum optics and ...

  10. Preservation theorems on finite structures

    International Nuclear Information System (INIS)

    Hebert, M.

    1994-09-01

    This paper concerns classical Preservation results applied to finite structures. We consider binary relations for which a strong form of preservation theorem (called strong interpolation) exists in the usual case. This includes most classical cases: embeddings, extensions, homomorphisms into and onto, sandwiches, etc. We establish necessary and sufficient syntactic conditions for the preservation theorems for sentences and for theories to hold in the restricted context of finite structures. We deduce that for all relations above, the restricted theorem for theories hold provided the language is finite. For the sentences the restricted version fails in most cases; in fact the ''homomorphism into'' case seems to be the only possible one, but the efforts to show that have failed. We hope our results may help to solve this frustrating problem; in the meantime, they are used to put a lower bound on the level of complexity of potential counterexamples. (author). 8 refs

    ública.Cet article a pour objectif d'analyser l'influence de la crise économique sur la formation de nouvelles coalitions politique dans l'Argentine des années 2000, qui ont mené à la rupture de la politique économique adoptée par les gouvernements Menem et De la Rúa. Ces transformations ont favorisé un changement dans la stratégie du gouvernement Néstor Kirchner concernant les relations avec le Fonds Monétaire International (FMI, ce qui a engendré une position plus dure de la part du gouvernement argentin et un rejet des positions du FMI. La politique économique soutenue par les gouvernements Duhalde et Kirchner s'est appuyée sur le régime de change compétitif, à la place du régime de conversion en vigueur dans les années 1990, et comptait sur l'appui des groupes d'entrepreneurs orientés vers le marché domestique, mieux lotis en fonction de la dévalorisation du « peso ». La proposition de ces gouvernements pour la relance économique a supprimé des acteurs ayant des liens étrangers, qui participaient à des coalitions d'appui sous Menem et De la Rúa. Parmi les exclus, figuraient les créanciers ayant des papiers de la dette en moratoire depuis 2001 et les entreprises offrant des services publics qui avaient été privatisées dans les années 1990 et qui ont reçu appui du FMI. Ces raisons expliquent le fait que les négociations avec le Fonds pendant le gouvernement Kirchner ont été marquées par des impasses et par l'attitude énergique de la part des négociateurs argentins. Des transformations dans le contexte international ont également eu des impacts sur les négociations du gouvernement Kirchner avec le FMI. Avec l'élections de George W.Bush aux États-Unis, en 2000, l'appui nord-américain à la concession d'emprunts du Fonds à des pays en développement s'est affaibli. Le gouvernement républicain a encore prôné la réduction du rôle du FMI dans l'intermédiation des négocitions entre les pays endettés et les créanciers privés. Ainsi

  14. Variational collocation on finite intervals

    International Nuclear Information System (INIS)

    Amore, Paolo; Cervantes, Mayra; Fernandez, Francisco M

    2007-01-01

    In this paper, we study a set of functions, defined on an interval of finite width, which are orthogonal and which reduce to the sinc functions when the appropriate limit is taken. We show that these functions can be used within a variational approach to obtain accurate results for a variety of problems. We have applied them to the interpolation of functions on finite domains and to the solution of the Schroedinger equation, and we have compared the performance of the present approach with others

  15. Finite elements of nonlinear continua

    CERN Document Server

    Oden, John Tinsley

    1972-01-01

    Geared toward undergraduate and graduate students, this text extends applications of the finite element method from linear problems in elastic structures to a broad class of practical, nonlinear problems in continuum mechanics. It treats both theory and applications from a general and unifying point of view.The text reviews the thermomechanical principles of continuous media and the properties of the finite element method, and then brings them together to produce discrete physical models of nonlinear continua. The mathematical properties of these models are analyzed, along with the numerical s

  16. Finite connectivity attractor neural networks

    International Nuclear Information System (INIS)

    Wemmenhove, B; Coolen, A C C

    2003-01-01

    We study a family of diluted attractor neural networks with a finite average number of (symmetric) connections per neuron. As in finite connectivity spin glasses, their equilibrium properties are described by order parameter functions, for which we derive an integral equation in replica symmetric approximation. A bifurcation analysis of this equation reveals the locations of the paramagnetic to recall and paramagnetic to spin-glass transition lines in the phase diagram. The line separating the retrieval phase from the spin-glass phase is calculated at zero temperature. All phase transitions are found to be continuous

    Full Text Available This article discusses the relationship between Le Corbusier and Alfred Roth, a member of the Paris office between 1927 and 1928. It also deals with the influence that this period had with reference to an important factor in Roth’s professional development, as in Le Corbusier’s later works: the use of colour in his architecture. This article takes the position that Roth, given his close friendship with Mondrian, was an important figure in turning Le Corbusier’s work towards greater use of primary colours and aesthetic neoplasticism.

    2018-01-01

    The following work is the first evaluating the applicability of 3D printed zirconium dioxide ceramic miniplates and screws to stabilize maxillary segments following a Le-Fort I advancement surgery. Conventionally used titanium and individual fabricated zirconium dioxide miniplates were biomechanically tested and compared under an occlusal load of 120N and 500N using 3D finite element analysis. The overall model consisted of 295,477 elements. Under an occlusal load of 500N a safety factor before plastic deformation respectively crack of 2.13 for zirconium dioxide and 4.51 for titanium miniplates has been calculated. From a biomechanical point of view 3D printed ZrO 2 mini-plates and screws are suggested to constitute an appropriate patient specific and metal-free solution for maxillary stabilization after Le Fort I osteotomy.

    Full Text Available Partant d’une phrase énigmatique datant de 1858 et puisée dans la Correspondance de Flaubert, cet article s’interroge sur la relation entre soleil et mythe, qui constituera l’un des éléments clefs de la dimension mythologique de Salammbô. Il se propose d’examiner la façon dont cette question apparaît dans deux ouvrages représentatifs des études mythographiques : d’une part, L’Origine de tous les cultes de Charles-François Dupuis, d’autre part, Les Religions de l’Antiquité..., publié sous les noms de Frédéric Creuzer et de son adaptateur français, Joseph-Daniel Guigniault. La version française de la grande synthèse de Creuzer, assortie d’une série importante de planches, a été richement exploitée par Flaubert au cours de la genèse du roman carthaginois. Dans Salammbô, le mythe apparaît sous de multiples formes. L’analyse de ce texte peut nous amener à réfléchir sur le « bon usage » du mythe auquel chaque créateur (et chaque lecteur se trouve nécessairement confronté.Starting from an enigmatic phrase in Flaubert’s correspondence, dating from 1858, this article examines the relation between the Sun and myth, which constitutes one of the key elements of the mythological dimension of Salammbô. It especially focuses on the treatment of this question in two representative works of mythographic studies, The Origin of All Religious Worship by Charles-François Dupuis, and Les Religions de l’Antiquité..., the French adaptation of Frédéric Creuzer’s Symbolik und Mythologie der alten Völker by Joseph-Daniel Guigniault. The French version of Creuzer’s great synthesis, supplied with a remarkable set of prints, was abundantly consulted by Flaubert when writing his Carthaginian novel. In Salammbô, myth takes on various forms. Analyzing this text might lead one to reconsider “the right way” to use myths — a problem all writers (and readers find themselves confronted with.

    2012-01-01

    The Gulf Coast Ecosystem Restoration Task Force (GCERTF) was established by Executive Order 13554 as a result of recommendations from “America’s Gulf Coast: A Long-term Recovery Plan after the Deepwater Horizon Oil Spill” by Secretary of the Navy Ray Mabus (Mabus Report). The GCERTF consists of members from 11 Federal agencies and representatives from each State bordering the Gulf of Mexico. The GCERTF was charged to develop a holistic, long-term, science-based Regional Ecosystem Restoration Strategy for the Gulf of Mexico. Federal and State agencies staffed the GCERTF with experts in fields such as policy, budgeting, and science to help develop the Strategy. The Strategy was built on existing authorities and resources and represents enhanced collaboration and a recognition of the shared responsibility among Federal and State governments to restore the Gulf Coast ecosystem. In this time of severe fiscal constraints, Task Force member agencies and States are committed to establishing shared priorities and working together to achieve them.As part of this effort, three staffers, one National Oceanic and Atmospheric Administration (NOAA) scientist and two U.S. Geological Survey (USGS) scientists, created and led a Science Coordination Team (SCT) to guide scientific input into the development of the Gulf of Mexico Regional Ecosystem Restoration Strategy. The SCT leads from the GCERTF coordinated more than 70 scientists from the Federal and State Task Force member agencies to participate in development of a restoration-oriented science document focused on the entire Gulf of Mexico, from inland watersheds to the deep blue waters. The SCT leads and scientists were organized into six different working groups based on expanded goals from the Mabus Report: Coastal habitats are healthy and resilient.Living coastal and marine resources are healthy, diverse, and sustainable.Coastal communities are adaptive and resilient.Storm buffers are sustainable.Inland habitats and

    The Le Chatelier principle states that physical equilibria are not only stable, but they also resist external perturbations via short-time negative-feedback mechanisms: a perturbation induces processes tending to diminish its results. The principle has deep roots, e.g., in thermodynamics it is closely related to the second law and the positivity of the entropy production.

    The author reports on discussions with two US companies about plans for using shuttle tankers to transport oil from platforms in the Gulf of Mexico to US ports as an alternative to pipeline networks. This follows approval by the US Minerals Management Service for FPSOs in the Gulf. The companies are American Shuttle Tankers and Conoco-owned Seahorse Shuttling and Technology. Because the vessels will enter US ports and operate in US waters, they must conform with the US Jones Act: they must be US-built, US-flagged and manned by US crews. They must also be double-hulled. This increases cost and reduces market opportunities for the vessels outside the US. The article also considers the use of articulated tug barges as another option. (UK)

    The future gas supply potential from the offshore Gulf of Mexico region was discussed with particular emphasis on the issue of whether there is enough growth potential to satisfy the anticipated growth in power generation markets. In 1980, a forecasted decrease in gas supply proved to be wrong. In fact, supply actually increased and productivity in the Gulf of Mexico has been relatively stable since 1982. A significant growth has been forecasted for 1997 to 2010. This growth will coincide with a large growth in gas demand in the northeastern U.S. The fact that electric power generation is changing hands adds to the opportunities in the northeast. It was emphasized that Canadian supply must be present to compete. 1 tab., 16 figs

    Hurricane Andrew's long term effect on Gulf of Mexico oil and gas operations likely won't be known until next year. This paper reports that while damage assessments have moved beyond the emergency stage, many offshore service companies say reliable estimates of the extent of damage or cost of repairs still are unavailable. The time needed to complete restorations won't be known conclusively until more organized surveys are complete. Even then, many contractors say, gulf operators must decide how to handle damage at each location-whether to repair damaged structures or replace them by applying technology not available when many of the fields were developed. Some damaged installations will not be replaced or restored, and the production will be lost

    2018-03-01

    The Gulf region is one of the most water-stressed parts in the world. Water in the region is very scarce, shortage of supply and lacking of renewable water resources, while the demand for water is growing day by day. It is thus essential to implement modern approaches and technologies in addressing water-related issues. In this context, isotope hydrology will provide invaluable aid. Some of the most important areas of futuristic applications of isotope hydrology include evaluation of aquifer recharge, storage and their recovery system, understanding of dynamic changes due to long-term exploitation of the groundwater, development and management of shared groundwater aquifers, fresh groundwater discharge along the Arabian Gulf, identification and quantification of hydrocarbon contamination in groundwater; soil moisture and solute movement in unsaturated zone, paleoclimate reconstruction, etc. Literature survey suggests, in general, not many isotope studies on the above have been reported.

    Because of the Environmental Protection Agency's recent toxicity limits on drilling mud discharges for offshore Gulf of Mexico, Phillips Petroleum conducted a mud toxicity study based on both field and lab tests. The study, discussed in this article, found the polyanionic cellulose-sulfomethylated quebracho-chrome lignosulfonate mud Phillips had been using would comfortably pass the toxicity limitations. The study also found barite and thinners were of low toxicity, and hydrocarbons and surfactants were highly toxic.

  1. Grand Gulf-prioritization of regulatory requirements

    International Nuclear Information System (INIS)

    Meisner, M.J.

    1993-01-01

    As cost pressures mount, Grand Gulf nuclear station (GGNS) is relying increasingly on various prioritization approaches to implement, modify, eliminate, or defer regulatory requirements. Regulatory requirements can be prioritized through the use of three measures: (1) safety (or risk) significance; (2) cost; and (3) public policy (or political) significance. This paper summarizes GGNS' efforts to implement solutions to regulatory issues using these three prioritization schemes to preserve a balance between cost and safety benefit

  2. Gulf Arab women's transition to motherhood.

    This paper is a report of the findings of a study of Gulf Arab women's perspectives of the transition to motherhood. Transition to motherhood is a universal phenomenon in which every culture has its own expectations and varying supports for women moving through this transition. International studies have provided models or categories of maternal responses related to cultural aspects of transition to motherhood. However, no known research has focused on transition to motherhood among Gulf Arab women. In the initial cohort seventeen first time Gulf Arab mothers in the United Arab Emirates were interviewed during the following three times: before childbirth, two-four weeks after childbirth, and forty-days after childbirth. A second cohort of seventeen first time new mothers was interviewed after childbirth in Sultanate of Oman. Four patterns were identified as indicators of change as women transitioned into motherhood: 1) Women's personal transition: women changed from feeling of freedom to feeling of dependency to self-confidence. 2) Mother/baby relationships: women changed from fear, anxiety, and uncertainty to feelings of care and confidence. 3) Family influences: women experienced family support to being integrated and feeling respected by family. 4) Cultural/religious beliefs and practices: women felt they were initially observers of culture, to experiencing cultural/religious beliefs and practices. This was followed by accomplishment in childbearing and childrearing practices. As Gulf Arab new mothers made the transition to motherhood, four implications for international nursing practice emerged: 1) patient teaching to help relieve anxiety, fears, and uncertainty, 2) facilitation of mother/baby relationships, 3) family-centered care, and 4) the importance of cultural/religious beliefs and practices to new mothers.

  9. Introduction to finite temperature and finite density QCD

    International Nuclear Information System (INIS)

    Kitazawa, Masakiyo

    2014-01-01

    It has been pointed out that QCD (Quantum Chromodynamics) in the circumstances of medium at finite temperature and density shows numbers of phenomena similar to the characteristics of solid state physics, e.g. phase transitions. In the past ten years, the very high temperature and density matter came to be observed experimentally at the heavy ion collisions. At the same time, the numerical QCD analysis at finite temperature and density attained quantitative level analysis possible owing to the remarkable progress of computers. In this summer school lecture, it has been set out to give not only the recent results, but also the spontaneous breaking of the chiral symmetry, the fundamental theory of finite temperature and further expositions as in the following four sections. The first section is titled as 'Introduction to Finite Temperature and Density QCD' with subsections of 1.1 standard model and QCD, 1.2 phase transition and phase structure of QCD, 1.3 lattice QCD and thermodynamic quantity, 1.4 heavy ion collision experiments, and 1.5 neutron stars. The second one is 'Equilibrium State' with subsections of 2.1 chiral symmetry, 2.2 vacuum state: BCS theory, 2.3 NJL (Nambu-Jona-Lasinio) model, and 2.4 color superconductivity. The third one is 'Static fluctuations' with subsections of 3.1 fluctuations, 3.2 moment and cumulant, 3.3 increase of fluctuations at critical points, 3.4 analysis of fluctuations by lattice QCD and Taylor expansion, and 3.5 experimental exploration of QCD phase structure. The fourth one is 'Dynamical Structure' with 4.1 linear response theory, 4.2 spectral functions, 4.3 Matsubara function, and 4.4 analyses of dynamical structure by lattice QCD. (S. Funahashi)

    The time evolution of coherent rotational wave packets associated to a diatomic molecule or to a deformed nucleus has been studied. Assuming a rigid body dynamics the J(J+1) law leads to a mechanism of cloning: the way function is divided into wave packets identical to the initial one at specific time. Applications are studied for a nuclear wave packed formed by Coulomb excitation. Exact boundary conditions at finite distance for the solution of the time-dependent Schroedinger equation are derived. A numerical scheme based on Crank-Nicholson method is proposed to illustrate its applicability in several examples. (authors) 3 refs.

    Full Text Available Dans cet article, l’auteur traite de la signification et de l’usage du concept d’ethos. Dans la sociologie classique, ce dernier a été utilisé pour comprendre et qualifier la rationalité socialement et éthiquement encastrée des conduites sociales. Exprimant l’intériorisation d’un principe organisateur de pratiques, dessinant une matrice globale des comportements, il est porteur d’une vision qui paraît datée à l’heure du “brouillage des classes sociales”, de la “modernité liquide” et de “l’homme pluriel”. Néanmoins, si l’on reconnaît l’existence d’un univers social non entièrement liquéfié, c’est-à-dire où continuent à exister des milieux sociaux sédimentés qui imprègnent avec plus ou moins de profondeur le système de personnalité de celui qui s’y insère durablement, l’ethos reste un concept heuristique pour saisir et interpréter les récurrences de comportements qui peuvent s’y observer. Permettant de comprendre ce que les espaces d’insertion “font aux individus” ainsi que la façon dont les principes organisateurs de pratiques entrent en transaction (en consonance, en dissonance ou en concurrence, il garde toute sa pertinence dans la boîte à outils théoriques du sociologue et de l’anthropologue d’aujourd’hui.

    New finite elements are needed as well in research as in industry environments for the development of virtual prediction techniques. The design and implementation of novel finite elements for specific purposes is a tedious and time consuming task, especially for nonlinear formulations. The automation of this process can help to speed up this process considerably since the generation of the final computer code can be accelerated by order of several magnitudes. This book provides the reader with the required knowledge needed to employ modern automatic tools like AceGen within solid mechanics in a successful way. It covers the range from the theoretical background, algorithmic treatments to many different applications. The book is written for advanced students in the engineering field and for researchers in educational and industrial environments.

    Ramos, Rudnei O.

    1996-01-01

    We apply the $\\delta$-expansion perturbation scheme to the $\\lambda \\phi^{4}$ self-interacting scalar field theory in 3+1 D at finite temperature. In the $\\delta$-expansion the interaction term is written as $\\lambda (\\phi^{2})^{ 1 + \\delta}$ and $\\delta$ is considered as the perturbation parameter. We compute within this perturbative approach the renormalized mass at finite temperature at a finite order in $\\delta$. The results are compared with the usual loop-expansion at finite temperature.

    We consider finite temperature effects upon theories with extra dimensions compactified via vacuum stress energy (Casimir) effects. For sufficiently high temperature, a static configuration for the internal space is impossible. At somewhat lower temperatures, there is an instability due to thermal fluctuations of radius of the compact dimensions. For both cases, the Universe can evolve to a de Sitter-like expansion of all dimensions. Stability to late times constrains the initial entropy of the universe. 28 refs., 1 fig., 2 tabs

    We discuss an application of finite temperature QCD to lepton-pair production in a quark-gluon plasma. The perturbative calculation is performed within the realtime formalism. After cancellation of infrared and mass singularities, the corrections at O (α s ) are found to be very small in the region where the mass of the Drell-Yan pair is much larger than the temperature of the plasma. Interesting effects, however, appear at the annihilation threshold of the thermalized quarks

The temperature-dependent effective potential for the vierbein which is parametrized as e sub(kμ) = b.diag(1, xi, xi, xi) has the minimum at b = 0 for fixed xi, and behaves as -xi 3 for fixed b. These results indicate that the system of fundamental matters in spinor pregeometry cannot be in equilibrium. (author)

    1991-03-01

    In this paper a 3D model for coupling of magnetic and electric equations is presented. The magnetic equations are solved with the help of finite element method using the magnetic vector potential formulation. To take into account the effects of magnetic saturation we use the Newton-Raphson algorithm. We develop the analysis permitting the coupling of magnetic and electric equations to obtain a difrerential system equations which can be solved with numerical integration. As example we model an iron core coil and the validity of our model is verified by a comparison of the obtained results with an analytical solution and a 2D code calculation. Dans cet article est présenté un modèle 3D qui permet de coupler les équations magnétiques et électriques. Les équations magnétiques sont résolues à l'aide de la méthode des éléments finis en utilisant une formulation en potentiel vecteur magnétique. Dans le modèle proposé les effets de la saturation du circuit magnétique sont pris en compte en utilisant l'algorithme de Newton-Raphson. On montre comment relier les équations magnétiques avec celles du circuit électrique pour aboutir à un système d'équations différentielles que l'on résout avec une intégration numérique. A titre d'exemple on modélise une bobine à noyau ferromagnétique et pour montrer la validité du modèle on compare les résultats obtenus avec une solution analytique et un code de calcul 2D.

The Saronikos Gulf, is directly influenced by the Athens metropolitan area. The operation of the Wastewater Treatment Plant of Athens situated on the small island of Psitalia, in 1995, was considered to be the turning point in the efforts of de-pollution of the gulf. Major sources of pollution for the gulf include also the port of Piraeus, with intensive navigation and shipping activities and the significant industrial activity occurring along the coast of Attica. This study of dissolved and particulate Zn gave results consistent with previous studies of the area such as the prevalence of the dissolved form of Zn and the most affected areas being the smaller most enclosed Gulf of Elefsina and Psitalia Island near the wastewater outfall. However, the concentrations of Zn were below toxic levels for marine aquatic organisms. Furthermore, a clear decrease in the Eastern part of the gulf was exhibited as well as a more subtle decrease in the gulf of Elefsina. The levels of Zn in Saronikos Gulf were found comparable to those of other Greek coastal areas.

  6. La lutte contre la désertification pour le développement durable des terres arides

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available Un des obstacles scientifiques le plus persistant pour la lutte contre la désertification a été une très grande difficulté dans la quantification soignée de la nature et l’extension du problème lié, dans le passé, à une difficulté dans la définition du phénomène. La Convention des Nations Unies sur la Lutte contre la Désertification (UNCCD a donné une définition à ce phénomène et a aussi établie un “zonage” sur base écologique en considérant un intervalle dans le rapport entre les précipitations et l’évaporation possible pour la définition des zones affectées par le phénomène. Un prise en charge direct du coté des pays touchés par la désertification ou dégradation des terres, par la réalisation des Programmes d’Action Nationale, est aussi un des piliers de la convention. L’extension croissante des phénomènes de dégradation des terres et l’inquiétude tant des pays concernés que de la communauté internationale ont déterminé la nécessité de disposer et de mettre au point des outils de suivi et d’évaluation des processus de dégradation des terres avec la création d’un réseau de surveillance.

  7. The Gulf of Mexico research initiative: It takes a village

    2016-07-01

    The Gulf of Mexico Research Initiative (GoMRI) was established at the time of one of the most significant ecological events in recent memory, the Deepwater Horizon oil spill. Defined by the discharge of over 150 million gallons of crude oil and the introduction of over 1.8 million gallons of chemical dispersants into the Gulf system, the impacts of the Deepwater Horizon disaster reached the Gulf Coast's wetlands and beaches and impacted the surface and deep ocean. The ecological story of the event reveals a strong linkage between the deep sea research community and research priorities in the Gulf of Mexico (coastal processes, human health, etc.). Deep Sea research efforts have revealed critical parts of the story, providing information on transport, fate, and effects of the Deepwater Horizon oil release and subsequent recovery of the Gulf of Mexico ecosystems.

    1992-01-01

    This paper reports that puny participation in the federal lease sale for the western Gulf of Mexico reflected a lack of open acreage on attractive prospects and the crisis sweeping the U.S. offshore oil and gas industry. Thirty-eight companies participating in the Minerals Management Service's Outer Continental Shelf Sale 141 offered 81 bids for 61 tracts in the western gulf planning area. That was the fewest bids offered in a western gulf sale since operators offered 52 bids for 41 tracts at Sale 105 in August 1986. The only Gulf of Mexico minerals sale to attract less bonus money was the MMS sulfur and salt sale in the central gulf in February 1988 in which $20.8 million was exposed

  5. Deepwater Gulf of Mexico: high prospects

    International Nuclear Information System (INIS)

    Kirkland, G.

    2000-01-01

    The present and future role of the deepwater Gulf of Mexico to meeting natural gas requirements of the United States are reviewed.The steady increase in U.S. demand, outpacing U.S.supply for over 10 years and the increasing reliance by the USA on Canadian exports is demonstrated in conjunction with the '30 Tcf Challenge'. Regarding the Gulf of Mexico specifically, it is estimated that to meet expectations, production there needs to grow to 22 Bcfpd by 2020, especially the deepwater pools which have a potential of 80 to 140 Tcf over the next 50 years. These pools already produce as much oil as the shelf region, but only 25 per cent as much gas. To produce the expected 7 to 12 Bcfpd oil production must reach 4 million barrel of oil per day, which involves cycle time, new technologies and cost challenges. Much of the new technology needed is related to cutting costs and while good progress is being made, it is argued that further gains could occur if international technology were applied in the Gulf. The rate of success in exploration has also improved, with over one billion barrels of deepwater discoveries per year over the last four years. Cycle times have also improved, although the impact of cycle time in the deeper water regions is cause for some concern. The overall assessment is that to get the gas, one has to get the oil first, meaning that deepwater success is more dependent on oil prices than on gas prices. Nevertheless, the need for developing and applying new technologies remains paramount, including the application of existing foreign technologies that have proven successful elsewhere. It is equally important to demonstrate a high level of environmental stewardship, and to continue focusing on cycle time, including access to prospective acreage, a well-trained workforce, and reasonable regulatory and permitting requirements

    The problem of computing quantum-accurate design-scale solutions to mechanics problems is rich with applications and serves as the background to modern multiscale science research. The prob- lem can be broken into component problems comprised of communicating across adjacent scales, which when strung together create a pipeline for information to travel from quantum scales to design scales. Traditionally, this involves connections between a) quantum electronic structure calculations and molecular dynamics and between b) molecular dynamics and local partial differ- ential equation models at the design scale. The second step, b), is particularly challenging since the appropriate scales of molecular dynamic and local partial differential equation models do not overlap. The peridynamic model for continuum mechanics provides an advantage in this endeavor, as the basic equations of peridynamics are valid at a wide range of scales limiting from the classical partial differential equation models valid at the design scale to the scale of molecular dynamics. In this work we focus on the development of multiscale finite element methods for the peridynamic model, in an effort to create a mathematically consistent channel for microscale information to travel from the upper limits of the molecular dynamics scale to the design scale. In particular, we first develop a Nonlocal Multiscale Finite Element Method which solves the peridynamic model at multiple scales to include microscale information at the coarse-scale. We then consider a method that solves a fine-scale peridynamic model to build element-support basis functions for a coarse- scale local partial differential equation model, called the Mixed Locality Multiscale Finite Element Method. Given decades of research and development into finite element codes for the local partial differential equation models of continuum mechanics there is a strong desire to couple local and nonlocal models to leverage the speed and state of the

The load estimate, recently released by USGS, is 7,316 metric tons per day. Based on that estimate, we predict the area of this summer’s hypoxic zone to be 18,900 square kilometers (95% credible interval, 13,400 to 24,200), the 7th largest reported and about the size of New Jersey. Our forecast hypoxic volume is 74.5 km3 (95% credible interval, 51.5 to 97.0), also the 7th largest on record.

  11. Le continu contre l'espace

    Science.gov (United States)

    Salanskis, Jean-Michel

    Disons pour conclure que, en tout état de cause, la façon de concevoir philosophiquement le conflit du continu et de l'espace que nous avons trouvée chez Hegel n'est pas homogène avec le style et les modalités de la pensée mathématique: 1) d'une part, le lien classique, le lien de référence entre continu et espace en mathématiques n'est pas que l'espace serait premier et privé de pensée, et le continu second, venant dissoudre l'espace en apportant la qualité, l'infini et la pensée, mais tout au contraire, il consiste en ce que l'espace est fondé sur l'abîme infinitaire du continu ; 2) d'autre part, l'éventuel divorce entre l'espace et le continu dans l'aire mathématique n'est pas celui d'une réflexivité purement conceptuelle du continu avec un positivisme géométrique, n'équivaut pas à une rupture disciplinaire ; il est plutôt le symptôme de la dérive d'une herméneutique à l'égard d'une autre, au sein d'un continent juridique commun définissant la discipline (la mathématique ensembliste), cette dérive pouvant, à la limite, induire une refonte de ce sol juridique, sans que jamais il soit question pour autant de nier l'unité des mathématiques, à comprendre ici comme l'unité ultime de responsabilité de la communauté mathématique à l'égard des trois questions Qu'est-ce que l'espace?”, “Qu'est-ce que le continu?” et “Qu'est-ce que l'infini?”.

    1996-01-01

    The property of some finite W algebras to be the commutant of a particular subalgebra of a simple Lie algebra G is used to construct realizations of G. When G ≅ so (4,2), unitary representations of the conformal and Poincare algebras are recognized in this approach, which can be compared to the usual induced representation technique. When G approx=(2, R), the anyonic parameter can be seen as the eigenvalue of a W generator in such W representations of G. The generalization of such properties to the affine case is also discussed in the conclusion, where an alternative of the Wakimoto construction for sl(2) k is briefly presented. (authors)

    In this review, I recall the nature and the inevitability of the "sign problem" which plagues attempts to simulate lattice QCD at finite baryon density. I present the main approaches used to circumvent the sign problem at small chemical potential. I sketch how one can predict analytically the severity of the sign problem, as well as the numerically accessible range of baryon densities. I review progress towards the determination of the pseudo-critical temperature T_c(mu), and towards the identification of a possible QCD critical point. Some promising advances with non-standard approaches are reviewed.

  17. Finite temperature approach to confinement

    International Nuclear Information System (INIS)

    Gave, E.; Jengo, R.; Omero, C.

    1980-06-01

    The finite temperature treatment of gauge theories, formulated in terms of a gauge invariant variable as in a Polyakov method, is used as a device for obtaining an effective theory where the confinement test takes the form of a correlation function. The formalism is discussed for the abelian CPsup(n-1) model in various dimensionalities and for the pure Yang-Mills theory in the limit of zero temperature. In the latter case a class of vortex like configurations of the effective theory which induce confinement correspond in particular to the instanton solutions. (author)

    CERN Document Server

    Landshoff, Peter V

    1992-01-01

    A prescription is presented for real-time finite-temperature perturbation theory in covariant gauges, in which only the two physical degrees of freedom of the gauge-field propagator acquire thermal parts. The propagators for the unphysical degrees of freedom of the gauge field, and for the Faddeev-Popov ghost field, are independent of temperature. This prescription is applied to the calculation of the one-loop gluon self-energy and the two-loop interaction pressure, and is found to be simpler to use than the conventional one.

    2009-12-01

    Full Text Available Le roman policier offre à l’étude du stéréotype une grande variété de redondances, lexicales et structurelles, qui permettent d’éclairer le concept même de genre, en fait issu du constat de stéréotypie. Il est également manifeste que contrairement aux idées reçues, les clichés font du texte policier un texte littéraire, parce qu’ils naissent d’images associées, distinctes de la réalité, qui révèlent d’ailleurs le cheminement même de l’écriture. Par ailleurs ces images jouent un rôle fondamental dans le plaisir du lecteur, comme dans les contes de fées de notre enfance. Les clichés ouvrent la porte des fantasmes : le stéréotype rejoignant l’archétype, les clichés policiers réactivent de nombreux mythes, le texte évoquant l’Autre Scène. Le constat de stéréotypie provoque l’écriture, en particulier parodique, et stimule le renouvellement et l’essaimage des clichés dans toutes sortes de textes, qui bénéficieront de la présence du déjà-lu, laquelle donne au lecteur une assise pour affronter l’inconnu et une expérience pour apprécier la nouveauté.

    2006-06-01

    Full Text Available Le « peer to peer » est la dynamique intersubjective caractéristique des réseaux distribués. Le but de cet essai est de montrer qu'il s'agit d'une véritable nouvelle forme d’organisation sociale, apte à produire et échanger des biens, à créer de la valeur. Celle-ci est la conséquence d'un nouvel imaginaire social, et possède le potentiel de devenir le pilier d'un nouveau mode d'économie politique, voire d'un nouveau type de civilisation. Pour cela, nous allons d'abord définir le P2P, décrire en bref ces manifestations, et le différencier d'autres modalités d'échange intersubjectif tel que le marché, la hiérarchie, l'économie du don.Comme principale modalité P2P nous distinguons: Les processus de production P2P, comme troisième mode de production, qui n'est ni géré par un mode hiérarchique ou par l'état, ni répondant à des impératifs de profit ou qui sont modulés par le biais des prix. Les processus de gouvernance P2P, qui gouverne ces processus de production. Les formes de propriété P2P, qui sont destine a empecher l’appropriation prive de cette production pour le commun.Afin d’examiner les characteristiques de cette nouvelle dynamique sociale, nous utilisons la typologie intersubjective de l’anthropologue Alan Page Fisque, qui distingue: 1. l'échange égalitaire (Equality Matching, c..a.d l’economie du don. 2. La relation d’autorité (Authority Ranking tel qu’elle s’exprime dans le mode hierarchique. 3. le marché (Market Pricing. 4. la participation commune (Communal Shareholding.En conclusion, nous examinons les possibilites d’expansion de ce nouveau mode sociale et son insertion dans l’economie capitaliste, en nous nous posons la question: le P2P peut-il etre concu comme alternative sociale et economique aux modeles existants.

  4. Représentation de l’espace et du temps dans le modèle situationnel construit par un lecteur

    Full Text Available Depuis plus de vingt ans, un des défis majeurs de la psycholinguistique est de décrire la nature de la représentation mentale construite par un lecteur. Si cette question est à l’étude depuis tant d’années, c’est que, contrairement à d’autres processus comme l’accès lexical ou l’analyse syntaxique, la compréhension d’un texte est restée pendant longtemps un objet difficilement étudiable scientifiquement en raison du manque de rigueur dans sa définition et de l’absence de modèles suffisamment explicites. Tel n’est plus le cas aujourd’hui. Les chercheurs s’accordent, en effet, pourdéfinir la compréhension d’un texte comme la construction d’une représentation situationnelle qui combine les propositions extraites du texte à celles qui ont été réactivées en mémoire à long terme afin de constituer une représentation non du texte, mais de ce dont le texte parle. Parmi les multiples dimensions censées être représentées dans le modèle situationnel, l’espace et le temps sont certainement ceux qui ont retenu le plus d’attention. L’objet du présent travail est de confronter nos connaissances à propos du rôle de ceux-ci lors de la construction du modèle situationnel. Une telle analyse semble particulièrement fructueuse parce que le temps et l’espace ont été étudiés selon deux points de vues différents et pourtant complémentaires. L’étude du temps s’est focalisée principalement sur les moyens linguistiques permettant d’exprimer celui-ci dans les textes (p. ex. les adverbiaux temporels et sur leur impact lors de la compréhension. Par contre, la manière dont les informations spatiales sont présentées dans un texte a retenu bien peu l’attention au profit de la question de savoir si et comment la multidimensionnalité de l’espace peut être reconstruite par le lecteur sur la base de la linéarité d’un texte. Un des objectifs spécifiques de ce travail est de proposer, sur

    Full Text Available Le scientifique promet la vérité sans être en mesure d'accomplir sa promesse tandis que l'écrivain promet de mentir mais par son mensonge, il fait plus que mentir. Il ne dit certainement pas la vérité, car la vérité n'est pas sa préoccupation première. Voilà comment nous pouvons résumer les deux attitudes, condamnées à un antagonisme stérile par l'attitude positiviste moderne. Compte tenu donc de l'intention fondatrice de la science, de sa promesse donc originaire et fondatrice, la science doit dire la vérité et rien que la vérité. Ce qui, de l'aveu même de cette même science, est impossible. [...] La littérature se permet de reconstruire des mondes par-delà le vrai et le faux. [...] Un récit littéraire ne demande pas la consécration de la vérité, ne demande pas à être suivi parce que vrai, n'impose rien et n'attend rien. Sa vraie destinée est l'errance et sa vraie conscience est celle de sa dissémination. Celui qui renonce à la prétention de vérité renonce en même temps à la volonté de dominer. Dominer signifie créer un espace de vérité dans lequel celui qui énonce la vérité est le maître légitime de ceux qui sont dans le champ de la conception du monde dont cette vérité est la pierre angulaire.

  7. Biset functors for finite groups

    CERN Document Server

    Bouc, Serge

    2010-01-01

    This volume exposes the theory of biset functors for finite groups, which yields a unified framework for operations of induction, restriction, inflation, deflation and transport by isomorphism. The first part recalls the basics on biset categories and biset functors. The second part is concerned with the Burnside functor and the functor of complex characters, together with semisimplicity issues and an overview of Green biset functors. The last part is devoted to biset functors defined over p-groups for a fixed prime number p. This includes the structure of the functor of rational representations and rational p-biset functors. The last two chapters expose three applications of biset functors to long-standing open problems, in particular the structure of the Dade group of an arbitrary finite p-group.This book is intended both to students and researchers, as it gives a didactic exposition of the basics and a rewriting of advanced results in the area, with some new ideas and proofs.

    In this series of lectures we will first review the general theory of phase transition in the framework of information theory and briefly address some of the well known mean field solutions of three dimensional problems. The theory of phase transitions in finite systems will then be discussed, with a special emphasis to the conceptual problems linked to a thermodynamical description for small, short-lived, open systems as metal clusters and data samples coming from nuclear collisions. The concept of negative heat capacity developed in the early seventies in the context of self-gravitating systems will be reinterpreted in the general framework of convexity anomalies of thermo-statistical potentials. The connection with the distribution of the order parameter will lead us to a definition of first order phase transitions in finite systems based on topology anomalies of the event distribution in the space of observations. Finally a careful study of the thermodynamical limit will provide a bridge with the standard theory of phase transitions and show that in a wide class of physical situations the different statistical ensembles are irreducibly inequivalent.

  9. Supersymmetry breaking at finite temperature

    Kratzert, K.

    2002-11-01

    The mechanism of supersymmetry breaking at finite temperature is still only partly understood. Though it has been proven that temperature always breaks supersymmetry, the spontaneous nature of this breaking remains unclear, in particular the role of the Goldstone fermion. The aim of this work is to unify two existing approaches to the subject. From a hydrodynamic point of view, it has been argued under very general assumptions that in any supersymmetric quantum field theory at finite temperature there should exist a massless fermionic collective excitation, named phonino because of the analogy to the phonon. In the framework of a self-consistent resummed perturbation theory, it is shown for the example of the Wess-Zumino model that this mode fits very well into the quantum field theoretical framework pursued by earlier works. Interpreted as a bound state of boson and fermion, it contributes to the supersymmetric Ward-Takahashi identities in a way showing that supersymmetry is indeed broken spontaneously with the phonino playing the role of the Goldstone fermion. The second part of the work addresses the case of supersymmetric quantum electrodynamics. It is shown that also here the phonino exists and must be interpreted as the Goldstone mode. This knowledge allows a generalization to a wider class of models. (orig.)

  10. Finite groups and quantum physics

    International Nuclear Information System (INIS)

    Kornyak, V. V.

    2013-01-01

    Concepts of quantum theory are considered from the constructive “finite” point of view. The introduction of a continuum or other actual infinities in physics destroys constructiveness without any need for them in describing empirical observations. It is shown that quantum behavior is a natural consequence of symmetries of dynamical systems. The underlying reason is that it is impossible in principle to trace the identity of indistinguishable objects in their evolution—only information about invariant statements and values concerning such objects is available. General mathematical arguments indicate that any quantum dynamics is reducible to a sequence of permutations. Quantum phenomena, such as interference, arise in invariant subspaces of permutation representations of the symmetry group of a dynamical system. Observable quantities can be expressed in terms of permutation invariants. It is shown that nonconstructive number systems, such as complex numbers, are not needed for describing quantum phenomena. It is sufficient to employ cyclotomic numbers—a minimal extension of natural numbers that is appropriate for quantum mechanics. The use of finite groups in physics, which underlies the present approach, has an additional motivation. Numerous experiments and observations in the particle physics suggest the importance of finite groups of relatively small orders in some fundamental processes. The origin of these groups is unclear within the currently accepted theories—in particular, within the Standard Model.

  12. A quasi-Lagrangian finite element method for the Navier-Stokes equations in a time-dependent domain

    Lozovskiy, Alexander; Olshanskii, Maxim A.; Vassilevski, Yuri V.

    2018-05-01

    The paper develops a finite element method for the Navier-Stokes equations of incompressible viscous fluid in a time-dependent domain. The method builds on a quasi-Lagrangian formulation of the problem. The paper provides stability and convergence analysis of the fully discrete (finite-difference in time and finite-element in space) method. The analysis does not assume any CFL time-step restriction, it rather needs mild conditions of the form $\\Delta t\\le C$, where $C$ depends only on problem data, and $h^{2m_u+2}\\le c\\,\\Delta t$, $m_u$ is polynomial degree of velocity finite element space. Both conditions result from a numerical treatment of practically important non-homogeneous boundary conditions. The theoretically predicted convergence rate is confirmed by a set of numerical experiments. Further we apply the method to simulate a flow in a simplified model of the left ventricle of a human heart, where the ventricle wall dynamics is reconstructed from a sequence of contrast enhanced Computed Tomography images.

  13. Meddy Interaction With A Deep Cyclone In The Gulf of Cadiz

    Science.gov (United States)

    Carton, Xavier; Cherubin, Laurent

    Hydrological measurements made in July 1999 in the Gulf of Cadiz reveal the presence of two meddies, one south of Cape Saint Vincent, the other one near the Moroccan shelf and their interaction with a deep cyclone. The thermohaline anomalies of the meddies reach 60-70 km diameter, and are concentrated between 750 and 1500m depths; they reach 2C and 0.5 in salinity. The cyclone is shallower (between 600 and 1300m) with a weaker signature of Mediterranean water (12C at 800m, 36.2 in salinity between 800 and 1200m). This cyclone is coupled with one of the meddies as a baroclinic dipole. This dipole tears a long warm and salty filament away from the other meddy at 1200m. The long term evolution of these eddies is described by means of deep-drogued drifting buoy trajectories: the isolated meddy drifts southwestward, the dipole remains coherent while moving along the continental shelf until it reaches Cape Saint Vincent where it splits. A three-layer quasi-geostrophic model is used to evaluate the possible origin of the meddy and cyclone near the Portuguese coast, and to assess if their interactions, both mutual, with the domain boundaries, and with bottom topography, can account for their motion and deformation.

  15. Site characterization plan: Gulf Coast salt domes

    1983-12-01

    The National Waste Terminal Storage (NWTS) program of the US Department of Energy (DOE) is responsible for developing technology and providing facilities for safe, environmentally acceptable, permanent disposal of high-level nuclear waste. The Office of Nuclear Waste Isolation has been intensively investigating Gulf Coast Salt Dome Basin salt domes and bedded salt in Texas and Utah since 1978. In the Gulf Coast, the application of screening criteria in the region phase led to selection of eight domes for further study in the location phase. Further screening in the area phase identified four domes for more intensive study in the location phase: Oakwood Dome, Texas; Vacherie Dome, Louisiana; and Richton Dome and Cypress Creek Dome, Mississippi. For each dome, this Site Characterization Plan identifies specific hydrologic, geologic, tectonic, geochemical, and environmental key issues that are related to the DOE/NWTS screening criteria or affect the feasibility of constructing an exploratory shaft. The Site Characterization Plan outlines studies need to: (1) resolve issues sufficiently to allow one or more salt domes to be selected and compared to bedded salt sites in order to determine a prime salt site for an exploratory shaft; (2) conduct issue-related studies to provide a higher level of confidence that the preferred salt dome site is viable for construction of an exploratory shaft; and (3) provide a vehicle for state input to issues.

  16. Gulf War Syndrome: a review of current knowledge and understanding.

    The 1991 Persian Gulf War was a resounding military success for coalition forces, who liberated Kuwait following the Iraqi invasion. The medical legacy we have from the conflict is the poorly understood, yet remarkable, phenomenon of Gulf War Syndrome, which surfaced soon after. Epidemiological research has proven beyond doubt that Gulf War veterans report a wide variety of symptoms, in excess of appropriately matched control subjects, and experience worse general health. Numerous toxic environmental hazards have been suggested as causes of Gulf War Syndrome, yet exhaustive scientific study has failed to provide conclusive proof of any link. No novel or recognised disease has been found to account for the symptomatic burden of veterans, and the optimal treatment remains uncertain. This understanding can be added to from an anthropological perspective, where the narratives of those afflicted provide further insight. The nature of military life was changing at the time of the Gulf War, challenging the identity and beliefs of some veterans and causing socio-cultural distress. The symptomatic presentation of Gulf War Syndrome can be considered an articulation of this disharmony. Gulf War Syndrome can also be considered within the group of post-combat disorders such as shellshock, the like of which have occurred after major wars in the last century. With the current withdrawal from Afghanistan, the Defence Medical Services (DMS) should heed the lessons of history.

    As a result of the 1991 Persian Gulf war, between mid-January and June 1991, the Persian Gulf was contaminated with an estimated 4 to 6 million barrels of crude oil, released directly into the Gulf from refinement facilities, transhipment terminals, and moored tankers along the coast of Kuwait, and precipitated from oil fire smoke plumes. To assess the environmental impact of the oil, an international team of marine scientists representing 14 nations was assembled under the auspices of the United Nations International Oceanic Commission and the Regional Organization for Protection of the Marine Environment to conduct detailed surveys of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman, including hydrographic, chemical, and biological measurements. To supplement the field surveys and to serve as an aid in data interpretation, astronauts aboard the Space Shuttle Atlantis photographed water features and coastal habitats in the Persian Gulf during mission STS-45 (24 March to 02 April 1992). The astronauts collected 111 hand-held, color photographs of the Gulf (72 70-mm photographs and 39 5-inch photographs) from an altitude of 296 km (160 n.mi.). The photographs reveal distributions in water turbidity associated with outflow from the Shatt-al-Arab and water circulation along the entire coast of Iran and the Strait of Hormuz, coastal wetlands and shallow-water habitats, and sticks appearing in the sunglint pattern, which appear to be oil.

    Lethal effects of mineral oils on fragile marine and coastal ecosystems are now well known. Risks and damages caused by a maritime accident can be reduced with the help of better forecasts and efficient monitoring systems. The MED project TOSCA (Tracking Oil Spills and Coastal Awareness Network), which gathers 13 partners from 4 Mediterranean countries, has been designed to help create a better response system to maritime accidents. Through the construction of an observational network, based on state of the art technology (HF radars and drifters), TOSCA provides real-time observations and forecasts of the Mediterranean coastal marine environmental conditions. The system is installed and assessed in five test sites on the coastal areas of oil spill outlets (Eastern Mediterranean) and on high traffic areas (Western Mediterranean). The Gulf of Naples, a small semi-closed basin opening to the Tyrrhenian Sea is one of the five test-sites. It is of particular interest from both the environmental point of view, due to peculiar ecosystem properties in the area, and because it sustains important touristic and commercial activities. Currently the Gulf of Naples monitoring network is represented by five automatic weather stations distributed along the coasts of the Gulf, one weather radar, two tide gauges, one waverider buoy, and moored physical, chemical and bio-optical instrumentation. In addition, a CODAR-SeaSonde HF coastal radar system composed of three antennas is located in Portici, Massa Lubrense and Castellammare. The system provides hourly data of surface currents over the entire Gulf with a 1km spatial resolution. A numerical modeling implementation based on Regional Ocean Modeling System (ROMS) is actually integrated in the Gulf of Naples monitoring network. ROMS is a 3-D, free-surface, hydrostatic, primitive equation, finite difference ocean model. In our configuration, the model has high horizontal resolution (250m), and 30 sigma levels in the vertical. Thanks

  3. Hybrid finite difference/finite element immersed boundary method.

    Science.gov (United States)

    E Griffith, Boyce; Luo, Xiaoyu

    2017-12-01

    The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of the fluid-structure system. The original immersed boundary methods described immersed elastic structures using systems of flexible fibers, and even now, most immersed boundary methods still require Lagrangian meshes that are finer than the Eulerian grid. This work introduces a coupling scheme for the immersed boundary method to link the Lagrangian and Eulerian variables that facilitates independent spatial discretizations for the structure and background grid. This approach uses a finite element discretization of the structure while retaining a finite difference scheme for the Eulerian variables. We apply this method to benchmark problems involving elastic, rigid, and actively contracting structures, including an idealized model of the left ventricle of the heart. Our tests include cases in which, for a fixed Eulerian grid spacing, coarser Lagrangian structural meshes yield discretization errors that are as much as several orders of magnitude smaller than errors obtained using finer structural meshes. The Lagrangian-Eulerian coupling approach developed in this work enables the effective use of these coarse structural meshes with the immersed boundary method. This work also contrasts two different weak forms of the equations, one of which is demonstrated to be more effective for the coarse structural discretizations facilitated by our coupling approach. © 2017 The Authors International  Journal  for  Numerical  Methods  in  Biomedical  Engineering Published by John Wiley & Sons Ltd.

    Allahverdyan, Armen E.; Galstyan, Aram

    2011-10-01

    The Le Chatelier principle states that physical equilibria are not only stable, but they also resist external perturbations via short-time negative-feedback mechanisms: a perturbation induces processes tending to diminish its results. The principle has deep roots, e.g., in thermodynamics it is closely related to the second law and the positivity of the entropy production. Here we study the applicability of the Le Chatelier principle to evolutionary game theory, i.e., to perturbations of a Nash equilibrium within the replicator dynamics. We show that the principle can be reformulated as a majorization relation. This defines a stability notion that generalizes the concept of evolutionary stability. We determine criteria for a Nash equilibrium to satisfy the Le Chatelier principle and relate them to mutualistic interactions (game-theoretical anticoordination) showing in which sense mutualistic replicators can be more stable than (say) competing ones. There are globally stable Nash equilibria, where the Le Chatelier principle is violated even locally: in contrast to the thermodynamic equilibrium a Nash equilibrium can amplify small perturbations, though both types of equilibria satisfy the detailed balance condition.
