    The perspectives given by the gas turbines under pressure, to build simple nuclear power plants and acieving significantly high yield, are specified. The CO{sub 2} is characterised by by good efficiency under moderate temperature (500 to 750 Celsius degrees), compactness and the simpleness of machines and the safe exploitation (supply, storage, relief cooling, thermosyphon). The revision of thermal properties of the CO{sub 2} and loss elements show that several direct cycles would fit in particular to the AGR type reactors. Cycles that would diverge a little from classical models and able to lead to power and heat generation can lead by simple means to the best results. Several satisfying solutions present for the starting up, the power regulation and the stopping. The nuclear power plant components and the functioning safety are equally considered in the present report. The conclusions stimulate the studies and realizations of carbon dioxide gas turbines in when approprite. [French] Les perspectives offertes par la turbine a gaz sous pression, pour construire des centrales nucleaires simples et de rendement progressivement eleve, se precisent actuellement. le CO{sub 2} se distingue par sa bonne efficacite a temperature moderee (500 a 750 degres celsius), la compacite et la simplicite des machines, et la surete qu'il apporte a l'exploitation ( approvisionnement, stockage, refroidissement de secours, thermosiphon). La revision des proprietes thermophysiques du CO{sub 2} et des elements de pertes montre que divers cycles directs conviendraient en particulier aux reacteurs agr ou derives. Des cycles s'ecartant peu des modeles classiques, et se pretant ulterieurement a la production simultanee d'electricite et de chaleur, peuvent conduire par des moyens simples aux meilleurs resultats d'ensemble. Plusieurs solutions satisfaisantes se presentent pour le demarrage, le reglage de la puissance et l'arret. Les composants de la centrale et la surete de fonctionnement sont

    After 4 years operation, experimentation and maintenance of the gas loops built especially for the nuclear fuel testing reactor Pegase, it appears desirable not only to gather together in a single document the essential characteristics and particularities of these devices and of their associated equipment, but also to give the reasons for the technical modifications and the way in which they were carried out; this is done here by the persons themselves who were responsible, day after day, for operating these loops. This essentially practically experience thus complements the careful research and preliminary testing carried out on these loops or on their prototypes. It should be of interest to those who deal with problems concerned with the design or operation of irradiation loops in experimental reactors or of similar equipment. (authors) [French] Apres 4 annees de fonctionnement, d'experimentation et d'entretien sur les boucles a gaz, construites specialement pour le reacteur d'essai des combustibles nucleaires Pegase, il a paru souhaitable non seulement de rassembler dans un meme document les caracteristiques et les particularites essentielles de ces dispositifs et des appareillages qui leur sont associes, mais aussi d'y preciser les raisons et les modalites des mises au point techniques, apportees par ceux qui, jour apres jour pendant cette periode, ont eu la charge de mettre en oeuvre ces boucles. Cette experience essentiellement pratique complete donc les etudes minutieuses et les essais preliminaires de ces boucles ou de leurs prototypes. Elle doit etre de quelque interet pour ceux qui sont confrontes aux problemes de conception ou d'exploitation de boucles d'irradiation dans des reacteurs experimentaux ou des dispositifs analogues.

  3. Developpement d'une methode de Monte Carlo dependante du temps et application au reacteur de type CANDU-6

    Science.gov (United States)

    Mahjoub, Mehdi

    La resolution de l'equation de Boltzmann demeure une etape importante dans la prediction du comportement d'un reacteur nucleaire. Malheureusement, la resolution de cette equation presente toujours un defi pour une geometrie complexe (reacteur) tout comme pour une geometrie simple (cellule). Ainsi, pour predire le comportement d'un reacteur nucleaire,un schema de calcul a deux etapes est necessaire. La premiere etape consiste a obtenir les parametres nucleaires d'une cellule du reacteur apres une etape d'homogeneisation et condensation. La deuxieme etape consiste en un calcul de diffusion pour tout le reacteur en utilisant les resultats de la premiere etape tout en simplifiant la geometrie du reacteur a un ensemble de cellules homogenes le tout entoure de reflecteur. Lors des transitoires (accident), ces deux etapes sont insuffisantes pour pouvoir predire le comportement du reacteur. Comme la resolution de l'equation de Boltzmann dans sa forme dependante du temps presente toujours un defi de taille pour tous types de geometries,un autre schema de calcul est necessaire. Afin de contourner cette difficulte, l'hypothese adiabatique est utilisee. Elle se concretise en un schema de calcul a quatre etapes. La premiere et deuxieme etapes demeurent les memes pour des conditions nominales du reacteur. La troisieme etape se resume a obtenir les nouvelles proprietes nucleaires de la cellule a la suite de la perturbation pour les utiliser, au niveau de la quatrieme etape, dans un nouveau calcul de reacteur et obtenir l'effet de la perturbation sur le reacteur. Ce projet vise a verifier cette hypothese. Ainsi, un nouveau schema de calcul a ete defini. La premiere etape de ce projet a ete de creer un nouveau logiciel capable de resoudre l'equation de Boltzmann dependante du temps par la methode stochastique Monte Carlo dans le but d'obtenir des sections efficaces qui evoluent dans le temps. Ce code a ete utilise pour simuler un accident LOCA dans un reacteur nucleaire de type

    The introduction, at an increasing rate, of power reactors using slightly enriched uranium will inevitably lead to the production of considerable quantities of plutonium over the next decade. Fast reactors will not be capable of absorbing this material before 1980. The question thus arises of whether one should store the plutonium far future use in fast reactors, recycle it in existing thermal reactors, or try to sell it. The problem has been studied for an electric power generating system that does not foresee selling the plutonium produced by its reactors and does not buy plutonium outside, which enables a good approximation to be made and eliminates the major unknown quantity represented by the future market price of plutonium. Assuming within this system a programme that provides for the construction of power reactors of a given type and capacity at specific dates, the utilization of the plutonium produced can be optimized by linear programming techniques so as to minimize the discounted total cost of the power generated over a given period. A later stage consists in optimizing, by various techniques, not only the utilization but also the production of plutonium by appropriate selection of the power reactor types to be constructed. (author) [French] L'implantation, a un rythme croissant, de centrales nucleaires a uranium legerement enrichi entrainera la production ineluctable d'une quantite importante de plutonium au cours de la prochaine decennie. Les reacteurs a neutrons rapides ne seront capables d'absorber cette production qu'apres 1980. La question se pose donc de savoir s'il est preferable de stocker le plutonium en vue de son utilisation ulterieure dans les reacteurs a neutrons rapides plutot que de le recycler dans les reacteurs actuels a neutrons thermiques ou d'essayer de le vendre. Ce probleme a ete etudie dans le cadre d'un systeme de production d'energie electrique qui ne prevoirait pas la vente du plutonium produit par ses reacteurs nucleaires ni

The methods proposed have proved practicable as a result of important research and developments on automatic remote control for all the operations which make up the sequences of mounting, demounting and repairing of the construction components. In particular the possibilities opened up by the new techniques of welding tubes from the inside have been extended to other problems connected with the assembling of a reactor. (authors) [French] Le coeur de ce reacteur est constitue par une cuve contenant l'eau lourde, cuve traversee d'une serie de tubes de force dans lesquels circule le gaz caloporteur sous pression de 60 at. Les specifications de depart qui ont joue un role important dans la conception de ces structures concernent des aspects de securite de fonctionnement (chargement du combustible par les deux faces du reacteur, remplacement des structures sur les deux faces du reacteur), des necessites neutroniques (absorption des structures minimum, pas du reseau, diametre des tubes de force) et des considerations thermiques (temperature de sortie 500 C). Ces specifications ont entraine une disposition horizontale des tubes de force et des problemes d'encombrement tres delicats qui ont elimine (pour les dimensions d'EL 4) toute possibilite de recourir a des compensateurs de dilatation sur les tubes de force. II s'ensuit un dessin de cuve semi-rigide dans lequel les tubes de force contribuent pour une part importante a la resistance mecanique de l'ensemble en jouant le role de tirant, d'ou des contraintes elevees sur les jonctions et tubes de force (et le choix des alliages de zirconium).

Plusieurs possibilites se presentent pour le demarrage d'un reacteur rapide a l'aide d'uranium-235. 1. Le reacteur peut etre alimente en permanence avec de l'uranium enrichi, le plutonium produit servant a demarrer et a alimenter d'autres reacteurs; dans ce cas, l'uranium est recycle dans le reacteur en y ajoutant de l'uranium enrichi. 2. Le plutonium produit dans le reacteur peut etre partiellement recycle dans celui-ci, ainsi que l'uranium; dans ce cas, le reacteur se transforme progressivement en un reacteur au plutonium. Ces deux cas peuvent etre combines pour un reacteur a plusieurs zones d'enrichissement, ou l'on peut appliquer simultanement les deux politiques a des zones differentes, c'est-a-dire: alimenter, par exemple, la zone interne en uranium enrichi et recycler le plutonium dans la zone externe.

With a view to reducing the dangers due to corrosion and contamination, the solution level in the core is raised by pneumatic pressure. The level is stabilized by means of a regulating system. During critical experiments the variations of the level are less than one hundredth part of a millimeter.

    In the framework of research into the poisoning of the EL-4 reactor by cadmium sulphate, measurements have been made by two different methods of the residual amounts of cadmium liable to be fixed irreversibly on the surfaces in contact with the heavy water. A marked influence of the pH has been noticed. The mechanism of the irreversible fixing is compatible with the hypothesis of an ion-exchange in the surface oxide layer. In a sufficiently wide range of pH the cadmium thus fixed causes very little residual poisoning. The stability of the cadmium sulphate solutions is however rather low in the conditions of poisoning. (authors) [French] Dans le cadre des etudes sur l'empoisonnement du reacteur EL-4 par le sulfate de cadmium, les quantites residuelles de cadmium susceptibles de se fixer irreversiblement sur les parois que mouillerait l'eau lourde, ont ete mesurees experimentalement par deux methodes differentes. On observe une influence nette du pH. Le mecanisme de la fixation irreversible est compatible avec l'hypothese d'un echange d'ions dans la pellicule d'oxyde superficielle. Dans des limites suffisamment larges de pH, la cadmium ainsi fixe n'occasionne pas d'empoisonnement residuel important. La stabilite des solutions de sulfate de cadmium dans les conditions de l'empoisonnement est cependant mediocre. (auteurs)

    The raise of the nuclear physics came with heavy mathematical developments. The analogical installations became especially useful for precise calculations of parameters which depend the running of a reactor. They permit between other to study of kinetic problems and especially ''cybernetics'' of nuclear reactors. It doesn't make a doubt that their use will become widespread, not only in the calculations laboratories, in services for servo-mechanisms study, but also in the control panels of the reactors themselves. (M.B.) [French] L'essor de la physique nucleaire s'est accompagne de lourds developpements mathematiques. Les montages analogiques sont devenus particulierement utiles pour les calculs precis des parametres dont depend le fonctionnement d'un reacteur. Elles permettent entre autre l'etude des problemes cinetiques et surtout ''cybernetiques'' des reacteurs nucleaires. Il ne fait pas de doute que leur usage se generalisera, non seulement dans les laboratoires de calculs, les services d'etudes de servomecanismes, mais aussi pres des tableaux de commande des reacteurs eux-memes.

    This report describes a method for determining by {gamma} spectrometry the burn up and the specific power of fuel elements irradiated in power reactors. The energy spectrum of {gamma} rays emitted by fission products is measured by means of a simple equipment using a sodium iodide detector and a multichannel analyzer. In order to extract from the spectrum a quantity proportional to the burn up, it is necessary to: - isolate an activity specific of one emitter,- give the same importance to fissions in uranium and plutonium - take into account the radioactive decay during and after irradiation. One hundred fuel elements were studied and burn up values obtained by {gamma} spectrometry are compared to results given by chemical analyses. Preliminary measurements show that the accuracy of the results is greatly increased by the use of a germanium detector, due to its good resolution. (authors) [French] Ce rapport expose une methode de determination par spectrometrie {gamma} du taux d'irradiation et de la puissance specifique des elements combustibles irradies dans les reacteurs de puissance. Une installation simple utilisant un detecteur d'iodure de sodium et un selecteur multicanaux mesure le spectre en energie du rayonnement {gamma} emis par les produits de fission. Afin d'extraire du spectre une quantite proportionnelle au taux de combustion, il faut: - isoler une activite specifique a un emetteur, - donner la meme importance aux fissions survenues dans l'uranium et le plutonium, - prendre en compte la decroissance radioactive pendant et apres l'irradiation. Les mesures ont porte sur une centaine d'elements combustibles et les taux de combustion obtenus par spectrometrie {gamma} sont compares aux resultats des analyses chimiques. Des mesures preliminaires montrent que l'utilisation d'un detecteur de germanium augmente considerablement la precision des resultats, en raison de son excellente resolution. (auteurs)

    organic liquids under irradiation. The equipments of Melusine are now being modernized. Siloe, another swimming-pool reactor, has been operating at 15 MW since the end of 1963. The performances achieved constitute a considerable progress in the field of swimming-pool reactors, since the fluxes obtained with Siloe are in the same order of magnitude than those which needed till now a tank type structure, whose numerous disadvantages in the fitting of experiments are well known. Siloe will be used mostly in the study of structural materials, graphites, refractory fissile materials, and for solid state physics. The reactor Pegase, in service in the Cadarache Nuclear Centre since 1963, is intended solely for testing full-scale fuel elements of EDF and EL 4 types. The current programme, for the eight loops of the reactor, covers the elements for the reactors EDF 2, EDF 3 and EL 4. New loops are in the course of being studied for the fuel elements of the EDF 4 and EDF 5 reactors. The general line of the CEA programmes has shown up the considerable need for fast neutron irradiations. The reactor Osiris which is in the course of being constructed will serve to complement the CEA's equipment in this field and at the same time fill the gap which will be left in the near future in the Centre de Saclay by the closing down of EL 2. Osiris is a light water reactor whose special structure will allow it to function at 50 MW without the disadvantages usually associated with the presence of a heavy waterproof tank. This reactor, which should be put into service in 1966, is mainly intended for the investigation of structural materials, graphite and refractory fuels; it will also serve to increase the production of high specific activity isotopes, and to develop activation analysis techniques.

    The power limit of swimming-pool type reactors depends on the phenomenon of the appearance of burn-out. In order to determine this limit we have attempted to detect the local boiling which usually occurs before the burn out. Local boiling has been simulated by an electrically heated plate placed in the core of the reactor Siloette. The study of local boiling, which is based on the properties of the correlation functions for the neutron noise of detectors placed in the core, shows that a privileged frequency occurs in the power spectrum of the noise. It is intended in the future to determine the influence of various parameters on this characteristic frequency. (author) [French] La limitation de la puissance des reacteurs nucleaires de type piscine est due au phenomene d'apparition de 'burn out'. Pour determiner cette limitation, nous nous sommes proposes dans ce rapport de detecter l'ebullition locale qui apparait generalement avant le 'burn out'. L'ebullition locale a ete simulee par une plaque chauffee electriquement et placee dans le coeur du reacteur SILOETTE. L'etude de l'ebullition locale, qui est basee sur les proprietes des fonctions de correlation du bruit neutronique de detecteurs places clans le coeur, fait apparaitre une frequence privilegiee dans le spectre de puissance du bruit. On envisage dans l'avenir, de determiner l'influence des divers parametres sur cette frequence caracteristique. (auteur)

(author) [French] Des mesures exponentielles sont faites aux laboratoires de Hanford sur des reseaux uranium-graphite depuis pres de quinze ans. Les resultats de ces experiences ont ete utilises pour determiner les laplaciens de reacteurs de production que l'on se proposait de construire, mais ils ont servi egalement a ameliorer les connaissances dans le domaine de la physique de ces systemes. On s'est rendu compte tres rapidement qu'en raison des dimensions des assemblages et de leur manque de sensibilite aux petites perturbations localisees du systeme, l'experience exponentielle n'a qu'une utilite limitee. On a donc envisage de mettre au point des experiences integrales avec un reacteur de maniere a reduire au minimum la quantite de matieres necessaires pour se procurer des donnees valables. A cet effet, on a construit une installation critique perfectionnee a plusieurs regions, qu'on a appelee 'reacteur d'etude des constantes physiques' (RECP), dont on s'est servi pour determiner les constantes physiques de plusieurs reacteurs de puissance. On s'en est servi aussi couramment pour mesurer des sections efficaces et determiner des parametres differentiels et integraux de la physique des reacteurs pour divers types de milieux multiplicateurs. Apres la construction de RECP, on a encore employe les experiences exponentielles, bien que RECP ait largement comble les espoirs qui avaient ete places en lui. L'auteur indique quelques donnees caracteristiques obtenues a l'aide de ces deux genres d'installations et compare leurs roles respectifs pour l'etude de nouveaux reacteurs de puissance, pour la modification de reacteurs en fonctionnement, comme moyens de recherche sur la physique des reacteurs et comme moyen de formation.

    Full Text Available Françoise Thébaud, en posant la question de savoir comment le genre structure les politiques de guerre, présente une intervention qui fait le point sur la « barbarisation » de la guerre dans le cadre de l’histoire du genre, à partir de la mise en évidence du passage du problème de l’émancipation, ou de l’autonomisation (cf. travaux des années 1960-1970, des femmes à celui de la réflexion plus récente sur la violence de guerre (depuis les années 1980 qui conteste la thèse de la guerre « émancipatrice » (si provisoire et superficielle qu’ait été cette émancipation. Dans ce cadre-là, la guerre en ex-Yougoslavie a pu jouer un rôle d’accélérateur de la prise de conscience du caractère très relatif de l’émancipation des femmes par la guerre des hommes. Certains historiens récents de la Première Guerre mondiale en viennent à travailler sur la culture de guerre qui serait le fondement d’une « brutalisation » du conflit au nom d’une « ethnicisation » de l’ennemi. Leurs thèses sont contestées par ceux qui rejettent l’idée d’un simple consentement à la guerre au profit d’un mélange complexe de contraintes, fraternité, patriotisme et refusent que la « culture de guerre » prenne le pas sur les autres cultures pré-existantes. La place des femmes et du genre dans la guerre est d’abord abordée par F. Thébaud à la lumière d’une double mythologie sexualisée (l’équation pureté nationale/pureté sexuelle et la féminisation de l’ennemi comme décadent et de l’autre mythe de la femme « naturellement » pacifiste en tant que mère potentielle. Or, les féministes ont adhéré massivement à l’effort de guerre et l’internationalisme « féministe » s’est effondré. Par ailleurs, la relative « humanisation » du conflit dont sont porteuses les femmes aux armées se fait toujours au service exclusif de la patrie. Dans un dernier volet de son intervention, F

    Full Text Available Le genre de la comédie musicale - ou musical en terminologie anglo-saxonne - représente un sujet d’actualité de la vie théâtrale serbe et française. La dernière décennie a donné un nouveau élan au genre, mais c’est notamment la période depuis l’année 2005 qui se caractérise par des nombreux changements importants dans la filière qui ont contribués au succès sans précédent de la comédie musicale à Belgrade et en Serbie. Mais aussi en France, dans un contexte le plus différent que possible du contexte serbe, l’année 2005 a donné de nombreux changements importants de la filière du théâtre musical en ce qui concerne la production et la réception du genre. Quand on observe la comédie musicale en Serbie et en France, il faut prendre en compte des différences de la nature terminologique mais aussi de la nature économique provenant de différents modes d’exploitation des spectacles.

    After resuming briefly the characteristics of the installations G2-G3 at Marcoule and EDF 1 at Chinon, the authors review the main aspects of the tests, the starting and the exploitation of these reactors. Among the various points examined, particular emphasis is given to the devices of original nature such as tubular fuel elements, flattening of the neutron flux by stuffing, behaviour of the reactor tanks and the cooling circuits, the blowers, unloading devices, regulation and functioning of the informations. This analysis deals equally with the performances obtained and the difficulties and the various incidents experienced during the initial starting period. Among the more interesting results, the progressive increase in the power of the Marcoule reactors is mentioned, obtained through a better knowledge of the parameters covering the functioning of the reactors such as the distribution of the flux and the temperatures etc... acquired during the course of the exploitation of the reactor. The conclusion reached by the authors is that the experience gained on these installations has shown: - that during an initial period, adjustments became necessary, all of which turned out to be possible, - that an analysis of their functioning has permitted the progressive movement towards a truly industrial exploitation.

    After a theoretical study on the slowing down of a centrifugal pump, the motion equations have been checked by means of experimental tests. In order to have important slowing down times (which is the case of the cooling pumps of a research reactor) it is necessary to add a fly-wheel. To prevent troubles when starting, a block pump-fly-wheel with clutch under controlled torque was developed. It is so possible to start the fly-wheel progressively without increasing too much power of the driving motor. (author) [French] Apres une etude theorique sur le mouvement de ralentissement d'une pompe centrifuge, les equations du mouvement ont ete verifiees par des essais pratiques. Pour obtenir des temps de ralentissement importants (cas des pompes de refrigeration d'un reacteur de recherche) il est necessaire d'y adjoindre un volant d'inertie. Pour eviter les inconvenients au demarrage, on a etudie un ensemble pompe-volant avec embrayage sous couple controle. Cette solution permet de lancer progressivement le volant sans augmentation appreciable de la puissance du moteur d'entrainement. (auteur)

    Full Text Available Le droit au développement semble animer tous les efforts visant à promouvoir la montagne marocaine, dans toutes ses dimensions politiques, sociales, organisationnelles à travers des projets de développement dont le plus réputé au Moyen Atlas est le projet MEDA-Khénifra. Ses actions diverses et ambitieuses ont façonné un douar de la région par de nouvelles organisations qui ont impacté les relations sociales et en particulier les relations du genre. Nous analysons à travers ce cas l’impact des projets de développement sur les relations du genre et l’empowerment des femmes dans cet espace. Les enquêtes ont été menées sous forme de questionnaires et d’entretiens collectifs. Le projet a créé deux organisations formelles : une association de développement et une coopérative pour la valorisation des plantes aromatiques et médicinales. Les femmes n’ont pas été impliquées dans ces organisations et certaines d’entre elles ont été invitées à participer à deux groupements informels. Le premier, pour la production de plantes aromatiques et médicinales, est resté sous la tutelle des organisations formelles gérées par les hommes. L’autre, dédié à l’apiculture, est plus autonome et a mieux réussi. Par ailleurs, la montée en puissance des organisations formelles a conduit à une moindre capacité d’action des femmes au niveau du village, car elles n’ont plus sur ces organisations les droits qu’elles ont traditionnellement dans le cadre de la jmâa. Cette expérience montre qu’un projet de développement peut influencer négativement les relations de genre malgré les bonnes volontés. La réflexion sur la question de genre doit alors impérativement animer l’ensemble des actions des projets de développement.

    The first French plutonium-making reactors G1, G2 and G3 built at Marcoule research center are linked to a power plant. The G1 electrical output does not offset the energy needed for operating this reactor. On the contrary, reactors G2 and G3 will each generate a net power of 25 to 30 MW, which will go into the EDF grid. This power is relatively small, but the information obtained from operation is great and will be helpful for starting up the power reactor EDF1, EDF2 and EDF3. The paper describes how, previous to any starting-up operation, the tests performed, especially those concerned with the power plant and the pressure vessel, have helped to bring the commissioning date closer.

    The design of a two-halves zero-energy fast reactor is briefly described, particular emphasis being placed on those features which determine the practicability and precision of reactor physics measurements. The advantages and disadvantages of the design are discussed with reference to the two years' operating experience of the reactor. The following topics are dealt with: the experimental convenience of the lay-out and of the two halves design; the size and precision of the fuel pieces and the accuracy of location of the fuel elements; the effects of edge irregularities and heterogeneity of structure on the accuracy with which the critical mass of an 'ideal' equivalent assembly is determined; reproducibility of the critical condition after dismantling the assembly, or separating the two halves; variation of reactivity with separation of the halves, including effects of asymmetric loading; sensitivity of various counters, neutron source strength, use of an accelerator neutron source; speed of response of safety circuits and consequent restrictions on rate of assembly of the two halves; additional precautions necessary in using plutonium fuel; and notes on the accuracy of measurement of reactivity and on the practical limitations affecting various other reactor physics measurements.

    Full Text Available L’objectif de la présente étude est de déterminer les raisons pour lesquelles un auteur du XVIe siècle aurait choisi la nouvelle forme analogique grande plutôt que la forme épicène grand. L’étude est basée sur un corpus de 1341 occurrences de cet adjectif au féminin dans 17 textes de cinq auteurs. L’hypothèse de l’identification du référent propose qu’un auteur aurait choisi cette forme pour indiquer clairement qu’elle modifie un substantif féminin et assurer ainsi le lien entre l’adjectif et le substantif. L’hypothèse de la concordance de genre propose que l’auteur aurait choisi grande pour faire accorder l’adjectif aux autres éléments féminins dans le syntagme nominal. Les résultats ont partiellement validé les deux hypothèses. La forme grande est favorisée quand elle ne précède pas immédiatement le substantif féminin qu’elle qualifie et quand un substantif masculin intervient entre le substantif féminin et grande. La forme analogique est aussi favorisée fortement par un déterminant féminin en -e et plus légèrement par la, mais pas par d’autres déterminants féminins. Nous avons trouvé en plus un résultat inattendu. La variante analogique est favorisée fortement quand elle modifie un substantif avec un plus grand nombre de syllabes et défavorisée par un substantif plus court.

    Canada's first nuclear power station, the Nuclear Power Demonstration station (NPD), is intended to serve as a means of proof-testing the performance of the Canadian type of station using natural uranium as fuel and heavy water as moderator and coolant. It reached full power on 28 June 1962. Although designed for base-load operation it will, during the early stages, be operated part of the time on high-capacity.runs and part of the time on improvement periods. Progress has been favourable so far; the first high-capacity run of six weeks'duration yielded a capacity factor of 70%. Improvements already made have increased safety, improved performance and demonstrated potential methods of capital-cost reduction for future stations. For example, shaft seals on primary coolant pumps have been modified for better performance, freezer-type vapour recovery equipment has been replaced in favour of absorption columns to reduce heavy-water vapour loss, and flow limiters are being installed in sample lines to reduce losses of heavy water in the event of joint failures. During December 1962 two simultaneous leaks from the on-power refuelling machine led to an unusual sequence of events in which a considerable amount of hot high-pressure heavy water was spilled into the reactor vault where it suffered a slight downgrading in isotopic purity. It was upgraded and the reactor returned to operation by the end of the month. All safety devices operated correctly during the incident as did the provisions for containment of heavy water.

    'Aquilon' is an experimental reactor specially designed for the neutronic study of heterogeneous multiplying media with solid fuel and liquid moderator. Since this study is in general incompatible with energy production, the power of the reactor has been limited to a minimum so as to be able to obtain a simple and compact structure, easy access, good handling and great flexibility of operation and utilisation.

    A study is made of the general case of the theory of first-order isotopic chemical exchange between a gaseous and a liquid phase in a reactor, starting from fundamental reaction kinetics data, and without making any limiting hypothesis concerning the value of the separation factor. The cases of counter-current reactors and of co-current reactors are considered successively. The general deuterium conservation equation requires the definition of the quotient of the reactor; the performances of this reactor are characterised by its overall efficiency. The idea of the ratio is introduced because it represents a convenient intermediary in the calculations. The search for an additive value for reactors in series leads logically to the defining of an exchange capacity, and a total efficiency, or number of theoretical reactors. This method of expressing the performances of a reactor is more general than the efficiency due to Murphee which only has a physical significance in the particular case of homogeneous liquid reactors. The relationships between these various quantities are established, and the representation due to Mc Cabe and Thiele is generalized. The reactor performances are linked to the first - order reaction kinetics by the transfer number. The relationships are given for a certain number of concrete cases. Finally the application of these calculations is given, together with the approximations necessary in the case where, because of the presence of several components in each phase, the exchange reaction no longer obeys a single kinetic law.

    A series of neutron measurements, for which the principal experimental methods perfected at the Marcoule reactors were used, was carried out at the start-up of EDF1. The measurements were designed mainly to determine the efficiency of the control rods at different depths of insertion. From them a rod-withdrawal configuration was derived which allowed full-power operation without infringing certain limitations on cladding and gas temperatures. At the same time flux measurements were made for different shim-rod positions and different absorber loadings in certain channels. These measurements based on preliminary two-dimensional calculations, were obtained by activation of point detectors,using the standard technique of air poisoning. At certain temperature plateaus (up to 140{sup o}C), measurements of temperature coefficients and control-rod efficiency were made. Spectrum index measurements were carried out at the same time by activation of appropriate detectors (U, Pu, Lu, Mn, In, Au). The oscillation technique was used to measure the efficiency of certain shim rods. Finally, fast-neutron measurements were made in connection with studies of shielding and graphite damage.

    The reaction probabilities in an infinite and homogeneous medium of BeO or Be have been calculated from neutron cross-section curves, for a neutron produced with an energy distribution similar to a fission spectrum; the calculation shows that, after several elastic collisions, the neutron has yet an appreciable probability to undergo a reaction, in spite of the energy degradation in the spectrum due to each collision. This degradation has been calculated, taking into account of anisotropy of the collisions. The gain of the reactivity in a reactor has been obtained after correcting these probabilities for the attenuation of the flux of fission neutrons due to the inelastic scattering in the uranium. Finally, the calculation shows that in a power reactor, this gain of reactivity is in practice destroyed in a few years by the accumulation of poisonous nuclei such as Li{sup 6} and He{sup 3} following (n, {alpha}) reaction.

    The isotopic composition of plutonium to be used as fuel for fast reactors will depend on the source of plutonium. In principle three different sources are possible: (a) production reactors; (6) thermal power reactors (using natural uranium or enriched uranium as fuel); (c) fast reactor blankets. In general, source (a) and to some extent source (c) will provide relatively 'clean' plutonium, that is mostly Pu{sup 239}, while plutonium from source (6) will be 'dirty' plutonium, that is plutonium rich in Pu{sup 240}, Pu{sup 241}, and Pu{sup 242}. The degree of 'dirtiness' will depend on the kind of reactor, amount of burn-up and in general on the irradiation history of the fuel. The question then arises, can one use as fuel for fast reactors any kind of plutonium? To investigate the effect of different isotopic composition of the plutonium fuel, in the metallic, oxide and carbide form, on the performance of fast reactors, a limited series of spherical geometry 16-group diffusion theory calculations were performed, using the 16-group cross-section set developed recently by Yiftah, Okrent and Moldauer and taking three different kinds of plutonium, starting with pure Pu{sup 239} and increasing the amount of higher isotopes. For the systems studied-800, 1500 and 2500-l core-volumes, which are typical for large fast power reactors-the result is, when one takes into account only the thermally fissionable isotopes Pu{sup 239} arid Pu{sup 241}, that the 'dirtier' the plutonium, the smaller the critical mass and the higher the breeding ratio. For the 1500-l reactor, taken as an example, it is further found that in the metallic, oxide and carbide plutonium fuels the reactivity change upon removal of 40% of the sodium initially present in the core is made more negative (or less positive) when the plutonium is richer in higher isotopes.

    Full Text Available L’article présente la problématique de ce dossier sur les temps sexués de l’activité. Il s’agit d’aborder l’activité − dans une acception large du travail, rémunéré ou non, plus ou moins visible, dans son articulation avec l’ensemble des sphères de la vie − comme miroir de l’imbrication du genre et des temporalités. Deux postures y contribuent. La plus classique consiste en une sociographie de la division sexuelle du travail où le temps sert à mesurer les inégalités. Il faut la compléter par une deuxième qui interroge les catégories temporelles : on montre ainsi que les temporalités sont au principe du système de genre. Ici le temps, appréhendé dans sa diversité et notamment ses dimensions qualitatives, résulte des pratiques et est posé comme producteur de rapports de pouvoir. La domination masculine repose sur la construction du rapport au temps : la naturalisation des compétences dites féminines s’appuie sur une temporalité basée sur le rapport à l’autre et l’engagement dans la durée. Les perspectives théoriques autour du care et de la présence sociale permettent de montrer les implications morales de l’engagement pour autrui dans ses dimensions temporelles (sens de l’anticipation, disponibilité à l’autre, ancrage dans la durée, temporalisation. Les auteurs exposent ensuite la manière dont chacune des contributions du numéro alimente cette discussion.We introduce this issue on the gendered times of work, broadly understood – i.e. paid or unpaid, and more or less visible – which, in conjunction with the other spheres of life, mirror the intricate interplay of Gender and Temporality.

Nous postulons que « this » fait partie des outils rhétoriques adaptés à un discours caractérisé par sa brièveté et son importance symbolique dans le champ académique. À partir d’un corpus constitué de résumés écrits en anglais dans cinq disciplines par des locuteurs anglophones et francophones, nous proposons une typologie des fonctions de « this » qui créent la focalisation et définissent une stratégie rhétorique. Nous distinguons une fonction exophorique qui ancre le résumé dans son contexte d’énonciation, d’une fonction endophorique qui fait progresser le texte d’un mouvement rhétorique à l’autre, selon des modalités allant de la reprise au déplacement et à l’englobement. L’application de cette classification aux sous-corpus de didactique des mathématiques et de sciences des matériaux permet de dessiner diverses stratégies de communication.

    We studied the variations of power and reactivity of a reactor when we raise in a continuous way the starting plates. During the subcritical regime (negative reactivity), the power is determined by reactivity and by the intensity of the sources of photo neutrons, produced during the previous work of the reactor. When, during the rise of the plates, the reactor, pass by the critical regime (zero reactivity), one notes that the reached power is independent of the initial reactivity. During the sur-critical regime (positive reactivity), the elevation of temperature of the uranium bars slows down the growth of reactivity due to the movements of the plates. The power stretches then toward a value that depends only on the regime of cooling of the reactor and the excess of the available reactivity. This survey permits to choose such a rise speed, that reactivity remains constantly lower to a value beyond which the piloting of the reactor becomes difficult. This result is not more valid, if the intensity of the sources is insufficient, what takes place during the first divergences and after a stop of long length. (author) [French] On etudie les variations de puissance et de reactivite d'un reacteur quand on leve d'une facon continue les plaques de demarrage. Pendant le regime subcritique (reactivite negative), la puissance est determinee par la reactivite et par l'intensite des sources de photoneutrons, produites pendant la marche anterieure du reacteur. Quand, au cours de la montee des plaques, le reacteur passe par le regime critique (reactivite nulle), on constate que la puissance atteinte est independante de la reactivite initiale. Pendant le regime surcritique (reactivite positive), l'elevation de temperature des barres d'uranium ralentit l'accroissement de reactivite due aux mouvements des plaques. La puissance tend alors vers une valeur qui ne depend plus que du regime de refroidissement du reacteur et de l'exces de la reactivite disponible. Cette etude permet de

It has been observed during with rapid cooling that there occurs a shortening at the base of the fins which can be accompanied in particular by a compression effect at the fin type, which has a tendency to curl, and by a tractive force acting on the body of the can at the ends of the longitudinal fins; this last phenomenon can result in a fracturing of the welds at the extremities or of the ends of the cartridge. This report presents first of all the way in which the stress diagram can be drawn for a can touching the fuel, and then the effect of the ratchet along a fin fixed to a bar with or without grooves. Finally the importance is shown of the test cycling variables (temperature, heating and cooling rates). (authors) [French] Les gaines des cartouches combustibles des reacteurs de la filiere graphite-gaz comportent soit des ailettes longitudinales plus ou moins epaisses, soit de courtes ailettes a chevrons, soit un ensemble des deux. Un test important de la tenue des cartouches, est la tenue au cyclage thermique en cellule pour reproduire le comportement en pile. On a observe au cours des cyclages a refroidissement rapide, un raccourcissement a la base des ailettes qui peut s'accompagner notamment d'une mise en compression du sommet de l'ailette qui a tendance a friser, et d'une traction exercee sur le corps des gaines au bout des ailettes longitudinales; ce dernier phenomene peut se traduire par des ruptures de soudures d'extremites ou des parties terminales de la cartouche. Ce rapport presente d'abord la maniere dont peut etre trace le diagramme des contraintes dans une gaine liee au combustible, puis l'effet du rochet le long d

Two-group diffusion theory is applied, and the conclusion can be drawn that fair agreement is obtained between theory and experiment for the perturbations in the lattice parameters for a void fraction equal to one, both at low and high temperatures. For intermediate void fractions, however, somewhat less satisfactory agreement is found. (author) [French] L'auteur a mesure, aussi bien lors d'experiences avec vide simule a puissance nulle que dans les conditions normales de puissance, l'effet cavitaire, provoque par l'ebullition qui se produit a l'interieur des canaux du refroidisseur, dans la deuxieme charge de HBWR. Les experiences avec vide simule ont consiste a mesurer les effets que produit sur la reactivite le fait d'enfoncer a des profondeurs differentes des tubes plus ou moins vides a paroi mince. Les tubes ont ete places en plusieurs endroits entre les barres, dans une seule cartouche formee de sept barres en grappe et pratiquement identique aux cartouches de combustible de la deuxieme charge. Cette experience permet de determiner comment la reactivite varie en fonction du volume cavitaire relatif et de l'emplacement des bulles dans le canal du refroidisseur. L'experience a ete effectuee dans le reacteur NORA de puissance zero, avec un coeur compose de 36 cartouches de la deuxieme charge de HBWR et dans une geometrie de reseau identique a celle de ce reacteur. L'auteur a observe comment l'effet cavitaire variait avec la temperature dans un ensemble de puissance zero avec le cceur a 100 cartouches de HBWR. Dans une seule cartouche, il a abaisse le niveau de l'eau a l'interieur du canal de refroidissement a des niveaux differents et mesure l'effet de cette perturbation sur la reactivite a differentes temperatures comprises entre 50 et 220 Degree-Sign C.

    The power of a nuclear reactor, in the operating conditions, presents fluctuations due to various causes. This random behaviour can be included in the study of 'noises'. Among other sources of noise, we analyse hereafter the fluctuations due: a) to the discontinuous emissions of neutrons from an independent source; b) to the multiplication of neutrons inside the reactor. The method which we present makes use of the analogies between the rules governing a nuclear reactor in operation and a number of radio-electrical systems, in particular the feed-back loops. The reactor can be characterized by its 'passing band' and is described as a system submitted to a sequence of random pulses. In non linear operating condition, the effect of neutron noise is defined by means of a non-linear functional, this theory is thus related to previous works the references of which are given at the end of the present report. This leads us in particular in the case of nuclear reactors to some results given by A. Blaquiere in the case of radio-electrical loops. (author) [French] La puissance d'un reacteur nucleaire, dans les conditions du regime, est affectee de fluctuations dont les causes sont tres diverses. Ce comportement aleatoire rentre dans le cadre general de l'etude des 'bruits'. Entre autres sources ce bruit, nous analysons ici les fluctuations dues: a) a l'emission discontinue des neutrons provenant d'une source autonome; b) a la multiplication des neutrons au sein du reacteur. La methode que nous introduisons exploite les analogies entre les lois qui regissent un reacteur nucleaire au regime et certains systemes radioelectriques, en particulier les circuits a boucle de reaction. Le reacteur est caracterise par sa 'bande passante' et est decrit comme un systeme soumis a une succession d'impulsions aleatoires. Dans les conditions de fonctionnement non lineaires, l'effet du bruit neutronique est precise en utilisant une fonctionnelle non lineaire, ce qui relie cette theorie a

    Full Text Available L’affaire Théophile est source de malentendus. Alors que l’historiographie du libertinage, en se concentrant sur le libertinage érudit a fini par oublier que la sodomie était un enjeu majeur du procès, les historiens de la répression homosexuelle abordent les relations sexuelles entre hommes dans une perspective essentialiste, gommant toute distinction entre sodomie au xviie siècle et homosexualité à l’époque contemporaine. Il s’agit donc la première partie de cet article de souligner que la sodomie est au cœur de l’affaire à la fois comme objet de représentation littéraire et comme pratique illicite. La seconde partie consiste dans une historicisation des discours ayant trait aux relations sexuelles entre hommes, qui montre qu’on ne saurait confondre « homosexualité masculine » et « sodomie ». Celle-ci désigne en effet des rapports anaux aussi bien entre hommes et femmes qu’entre hommes seuls ; lorsque la notion est mobilisée pour renvoyer à des relations anales entre hommes, elle ne constitue pas pour autant une orientation sexuelle ; en tant que concept issu de la théologie, elle ne relève pas de la sexualité ; aucune déviation de genre ne lui est associée. Dans une troisième partie, il s’agit de montrer que la notion de sodomie ne doit pas nous conduire à ignorer les autres discours pouvant porter sur les relations sexuelles entre hommes dans la France du premier xviie siècle et qu’à ce titre, on ne saurait se suffire de cette catégorie pour aborder la question. Bref, cet article a pour but de poser les premiers jalons d’une histoire de l’homosexualité masculine dans la France du xviie siècle d’un point de vue historiciste, sinon constructionniste.Sodomy in the Theophile de Viau affair: questions of gender and sexuality in early modern France.There is a puzzling misunderstanding about the Theophile affair.

    electro-magnetic method for technical as well as economic reasons. The optimum area of application of these two methods is explained as well as the large area of overlap where results produced by well- designed and properly operated equipment of both types are essentially equivalent. Spurious defect indications contribute directly to increased component costs, so an evaluation of these effects for both the ultrasonic and the electromagnetic test methods is included for several commonly encountered sources of spurious defect signals. The experience in the application of these methods at Argonne National Laboratory on relatively large quantities of tubing from various sources are recounted from the standpoint of the lowest possible inspection cost per unit length of tubing. This section also summarizes experience gained at Argonne with the newer pulsed electromagnetic test methods. The critical but generally unappreciated role of tube diameter and wall thickness on tube inspection cost is discussed. Since the question of economical inspection is closely related to allowable defect levels, defect levels and standards in use at Argonne are covered. Finally, the practical and theoretical barriers to reduced component inspection costs are enumerated and a projection of what possible reductions in cost might be attainable in the future with the ultrasonic and electromagnetic test methods is attempted.

    modeles neutroniques 2D et 3D du coeur du reacteur ont ete crees, bases sur le schema de calculs de reference ERANOS-2.0/ERALIB1. Pour l'analyse thermo-hydraulique, le code COPERNIC du CEA a ete utilise. Le travail de design a ete poursuivi par l'etude d'un schema de l'implantation des assemblages de controle (nombre et position dans le coeur). Des etudes detaillees de neutronique ont reveles l'existence de grands effets d'interaction entre les AC, appeles effets d'ombre/d'anti-ombre, conduisant a une amplification/reduction de l'antireactivite des AC. Les interactions entre les barreaux absorbants a l'interieur d'un AC, ainsi qu'entre les AC eux-memes, ont ete investiguees dans le detail, dans le but d'optimiser l'efficacite des AC (en terme de la fraction d'absorbant et la minimisation des effets d'heterogeneite associes). Resultant d'investigations detaillees, le diametre des pastilles absorbantes a ete choisi de maniere a minimiser l'influence 'barreau-a-barreau' a l'interieur de l'assemblage. En particulier, une partie centrale de l'assemblage a ete concue sans aucun barreau absorbant (zone remplie d'helium statique). Par ce biais, une reduction, a 13%, des effets d'heterogeneite, a ete obtenue. Les investigations neutroniques effectuees pour le coeur RNR-G de reference ('2004-Coeur'), specialement, celles liees a l'Etude des interactions entre les AC, ont directement contribue au nouveau design du coeur ('2007-Coeur').

    In search for semiconductors, which can be used in high-flux reactors in order to measure flux distributions, we irradiated SiC p-n junctions in the Belgium BR-1 reactor. Two types of SiC-diodes of different origin have been irradiated. These junctions are grown in the Lely-furnace. The change in forward and reverse characteristics have been measured during and after irradiation up to temperatures of 150{sup o}C, while measurements up to a temperature of 500{sup o}C are in progress. It has been found that one type resists BR-1 neutrons up to an integrated flux of 10{sup 15} n/cm{sup 2}, while the other resists irradiation up to a flux of 10{sup 17} n/cm{sup 2}. The changes in characteristics are given as well as the result of some annealing experiments.

Bien que ces reacteurs restent essentiellement plutonigenes, on a accole a chacun d'eux une centrale electrique devant fournir 40 MW, dont la responsabilite a ete assumee par l'E.D.F. Le coeur du reacteur adopte la plupart des solutions du reacteur G1 (excepte la fente centrale): canaux horizontaux, empilement de briques parallelepipediques de graphite, protection thermique en acier. Le refroidissement est assure par du gaz carbonique sous 15 atmospheres. Cette pression est tenue par un caisson en beton precontraint, ayant la forme d'un cylindre horizontal. Des cables d'acier sous tension entourent le cylindre de beton, dont ils sont isoles par des patins. Les fonds du cylindre ont pose des problemes particuliers qui ont conduit a la forme hemispherique adoptee. L'etancheite du caisson est assuree par une tole de 30 mm liee a la face interne du beton. Un des aspects les plus originaux de ces reacteurs est la possibilite de charger et decharger en marche. Cote chargement, des sas a barillets, pesant chacun 50 tonnes; permettent de faire passer les cartouches neuves sous la pression de 15 atmospheres. Ces cartouches progressent de facon quasi continue dans le canal pour tomber finalement par des goulottes inclinees et des toboggans helicoidaux dans un nouveau sas.

Ce choix etant fait, apres mise au point en laboratoire, deux nouveaux problemes se posent: - la transposition dans le domaine industriel; - la necessite de tenir compte de la qualite permise, a un instant determine, par les procedes de fabrication, en relation avec les normes de reception definies de maniere plus ou moins arbitraire. Ceci se traduit en fait par la necessite d'une etude statistique sur des lots de tubes de diverses provenances, et leur classement par rapport a des seuils plus ou moins severes. On verra que le nombre de tubes a controler est tres superieur a celui prevu initialement. Cela conduit a l'etude d'une machine de controle automatique, capable de satisfaire a la fois les exigences de cadence et celles propres au type de controle choisi: ces dernieres sont generalement d'ordre mecanique et necessitent une construction particulierement soignee. L'ensemble de ces considerations a conduit a concevoir une machine dont la cadence peut des maintenant couvrir sans difficulte les besoins d'une chaihe de fabrication d'elements combustibles. Les possibilites de cette machine sont etroitement liees aux caracteristiques du materiel de controle choisi, en particulier aux performances de l'electronique des appareils de controle par ultrasons et a celles des traducteurs utilises.

    Full Text Available Les caractéristiques d’un genre de discours découlent de la situation de communication dans laquelle il s’inscrit, et qu’il reflète. Pour une correspondance, et singulièrement pour une correspondance d’auteurs, cette situation est celle d’une interaction à la fois directe et biaisée qui engage l’ethos de l’épistolier. Nous analysons les idéaux qu’il produit sur un fond de valeurs partagées. Le champ d’investigation retenu est celui de certaines correspondances célèbres du 18e siècle, car la lettre est à cette époque une manifestation très accomplie de la sociabilité. De ce fait, elle a connu une dérive littérarisante, source d’un décalage pragmatique qui l’attire dans la mouvance d’un genre second, la correspondance littéraire, où l’implication éthique du discours devient sa détermination majeure.The characteristics of a genre of discourse depend upon its specific situation of communication - the genre being embedded in this situation and, at the same time, reflecting it. Concerning correspondences, especially between authors, this situation consists of an interaction both direct and indirect, involving the ethos of the letter writer. Our analysis focuses on the ideals it produces on a background of shared values. The field of inquiry is a choice of famous correspondences of the 18th century, since the letter was at that time an accomplished manifestation of sociability. As such, it adopted a literary form, which created a pragmatic gap and put it under the dependence of another genre, the fictional correspondence, in which ethic implications became its determining factor.

    In Quebec (Canada), the Work-Oriented Training Path, a work-study program, prepares students who are having difficulty at school for the job market. Occupational health and safety is an important part of their training. This article aims to analyze the impact of gender on the interpersonal dynamics among teachers, trainees, and key actors from the businesses involved. This article also looks at the influence of gender on teachers' strategies and capacity to act regarding occupational health and safety. Using a work activity analysis lens, a multiple case-study analysis of teachers' work activity was carried out. The findings show that gendered social relationships create a specific supervisory context that influences occupational health and safety training. Solutions aimed at reducing the negative impact of gender-associated prejudice on work injury prevention include training for teachers, attention to work organization at the schools, and the creation of cohesive teachers' work teams. Résumé Au Québec, le Parcours de formation axée sur l'emploi (WOTP), un programme en alternance, offre une préparation au marché du travail aux élèves en difficultés scolaires. La santé et la sécurité du travail (SST) est un enjeu important de la formation. L'article vise à analyser l'impact du genre dans la dynamique relationnelle entre les enseignant.es, leurs élèves et les interlocuteurs clés des entreprises impliquées, et son influence sur les stratégies et la capacité d'agir des enseignant.es en matière de SST. Une analyse de cas multiples basée sur l'analyse ergonomique de l'activité des enseignants a été menée. Les résultats montrent que les relations sociales de genre déterminent un contexte spécifique de supervision qui influence la formation à la SST. La formation des enseignant.es, l'organisation scolaire et la création de collectifs enseignants cohésifs sont des pistes de solution pour réduire l'effet négatif des préjugés liés au genre

    A review is made of the circumstances which favor a good collection of maintenance data at the C.E.A. The large amount of data to be treated has made necessary the use of a computer for analyzing automatically the results collected. Here, only particular aspects of the reliability from the point of view of the electronics used for nuclear reactor control will be dealt with: sale and unsafe failures; probability of survival (in the case of reactor safety); availability. The general diagrams of the safety assemblies which have been drawn up for two types of reactor (power reactor and low power experimental reactor) are given. Results are presented of reliability analysis which could be applied to the use of functional modular elements, developed industrially in France. Improvement of this reliability appears to be fairly limited by an increase in the redundancy; on the other hand it is shown how it may be very markedly improved by the use of automatic tests with different frequencies for detecting unsafe failures rates of measurements for the sub-assemblies and for the logic sub-assemblies. Finally examples are given to show the incidence of the complexity and of the use of different technologies in reactor safety equipment on the reliability.

    Chemical and isotope pollution, and radiolytic decomposition are the two most important ways in which heavy water becomes degraded in nuclear reactors. Chemical pollution has led to the creation of ion exchange purification loops specially designed for reactors: the report contains a description in detail of the application of this purification method in CEA research reactors, including the analysis required, results obtained, and their interpretation. The intelligence obtained on radiolytic decomposition with the same facilities is also discussed, as well as the recombination apparatus and control equipment utilized. Finally, investigation to date in the CEA on recombination circuits for power reactors is also discussed.

    Due to safety rules running on fourth generation reactors' core development, neutronics simulation tools have to be as accurate as never before. First part of this report enumerates every step of fast reactor's neutronics simulation implemented in current reference code: ECCO. Considering the field of fast reactors that meet criteria of fourth generation, ability of models to describe self-shielding phenomenon, to simulate neutrons leakage in a lattice of fuel assemblies and to produce representative macroscopic sections is evaluated. The second part of this thesis is dedicated to the simulation of fast reactors' core with steel reflector. These require the development of advanced methods of condensation and homogenization. Several methods are proposed and compared on a typical case: the ZONA2B core of MASURCA reactor.

    An attempt has been made to develop certain ideas concerning homogeneous reactors. The project under consideration is based on the simultaneous use of a suspension of uranium dispersed in heavy or light water and of boiling in the reactor for heat extraction. However, the studies of suspensions and of boiling are relatively independent and can also be developed for reactors of different types using one or the other. Our aim is a minimum investment in fissile material; for this we propose to extract the steam directly from the core and to make use of a cyclone to accelerate this extraction; a cyclone-type circulation creating a field of increasing tangential velocities of the fluid towards the axis causes the droplets of vapour to accelerate towards the axial vortex in which they are collected; the steam output is then evacuated to the external heat utilisation system, for example an exchanger of the condenser-boiler type. The input speed of water into the reactor being one of the important parameters in the running of the pile, a spiral supply input chamber is used, allowing this speed to be regulated in amount and direction.

Research on gender and creative labour typically identifies external, systemic and structural causes for gender inequality in media industries. In contrast, I argue that genres......, by virtue of their internal, structural and discursive patterning, play a constitutive role in regulating media producers’ gendered professional identities, shaping their struggle for recognition and structuring their economic sustainability.

    Full Text Available Les discours sociaux publiquement produits dans les sociétés occidentales contemporaines mettent en oeuvre des opérations de stéréotypages qui évoquent des représentations bien connues et parfois opposées, conformes ou non aux catégorisations psycho-sociales profondes. Leurs fonctions premières ne semblent pas être de renforcer les catégorisations de genre les plus traditionnelles ou de promouvoir leurs avatars modernes opposés, mais bien plutôt de les rendre compatibles entre elles, au risque de les vider de leurs significations premières au profit d’un Imaginaire social qui les concilierait toutes à la façon dont les mythes tentaient eux aussi pour Levi Strauss d’opérer une conciliation et un dépassement de représentations sociales contraires dans les sociétés antérieures. Ces discours suscitent aussi des phénomènes importants de résistance dits de “reactance”. Des psychologues proposent aussi de renforcer la résistance à cette persuasion qu’ils ont d’ailleurs souvent étudiée de près.

    Recent work in the sociology of music suggests a declining importance of genre categories. Yet other work in this research stream and in the sociology of classification argues for the continued prevalence of genres as a meaningful tool through which creators, critics and consumers focus their attention in the topology of available works. Building from work in the study of categories and categorization we examine how boundary strength and internal differentiation structure the genre pairings of some 3 million musicians and groups. Using a range of network-based and statistical techniques, we uncover three musical “complexes,” which are collectively constituted by 16 smaller genre communities. Our analysis shows that the musical universe is not monolithically organized but rather composed of multiple worlds that are differently structured—i.e., uncentered, single-centered, and multi-centered.

    This report brings together the principal methods of fission-product detection used for water reactors. The position, type and method of adjustment is given for each detector. The methods for localizing the defective elements are explained, in particular those using water sampling or decreases in the flux. A few installations are briefly described. They correspond to particular types of reactors using boiling, pressurized or cold water. Amongst the many methods used, it can be noted that when the fuel is resistant, the installations are fairly compact. In nuclear super-heated reactors on the other hand, the study of fuel behaviour calls for larger installations. An identification of defective elements exists when the reactor structure allows it. If this is not possible, a localization in a group of elements is obtained by a flux depression. (author) [French] Ce rapport rassemble les principales methodes de detection de produits de fission utilisees pour des reacteurs a eau. On indique pour les detecteurs leurs emplacements, leurs types, leurs reglages. On explique quelles sont les methodes de localisation des elements defectueux, en particulier celles utilisant des prelevements d'eau ou des depressions de flux. Quelques installations sont decrites sommairement. Elles correspondent a des types particuliers de reacteurs a eau bouillante, pressurisee ou froide. Parmi les nombreuses methodes utilisees, on constate que les installations sont peu importantes, lorsque le combustible est resistant. Par contre dans les reacteurs a surchauffe nucleaire l'etude du comportement du combustible necessite des installations plus importantes. Une identification d'elements defectueux existe lorsque la structure du reacteur le permet. A defaut une localisation dans un groupe d'elements est obtenue par depression de flux. (auteur)

    Full Text Available L’opposition à la guerre du Viêtnam (1964 – 1973 fut sans précédent aux Etats-Unis, avec les universités comme « épicentre du mouvement ». Sous-groupe constitutif de cet ensemble, les étudiantes méritent une attention particulière, car l’articulation entre sexualité et guerre est une notion fondamentale de l’Histoire et de toute histoire de guerre. En outre, leur nombre croissant depuis le milieu des années 1950 suggère qu’elles constituèrent une « force » militante nouvelle et imprévue de l’opposition à la guerre. Il s’agira donc de déterminer ce qui caractérise le militantisme « au féminin ». On s’interrogera sur la perception de leur rôle, qui oscille entre tradition et changement. Ces regards engagent la notion de la légitimité de l’engagement et du degré de visibilité de ces femmes que nous examinerons. En dernier lieu, nous soulèverons la question des conséquences du décalage et des incohérences entre la rhétorique du Mouvement et la réalité des rôles de chacun. Ainsi, nous nous attacherons à déterminer si cette incursion dans la sphère publique et politique du militantisme a généré un nouveau discours.La oposición a la guerra de Vietnam (1964-1973 no tuvo precedentes en la historia de Estados Unidos y las universidades ocuparon el centro del escenario de esta oposición. Como subgrupo las alumnas merecen una atención especial por varias razones: en primer lugar la interacción entre sexualidad/género y la guerra es parte de la historia y parte de la historia bélica y en segundo lugar el incremento continuo de éstas desde mediados de los 50 en adelante sugiere que se convirtieron en una “fuerza” inesperada que se añadió a la oposición contra la guerra. De este modo, este ensayo explora lo que motivó la experiencia activista femenina. Después se destaca la percepción de sus roles que oscilaban entre la tradición y el cambio.

    The solution to the correlation equations are expressed in terms of the eigenvalues and Eigen-matrices of the transport operator, for a subcritical zero power reactor. This allows to define, for each point of the reactor and for detectors detecting neutrons of given velocities, correlation and transfer functions driven by the same white-noise source. A precise meaning is also given to the importance operator, which is the adjoin of the transport operator. (author) [French] La solution des equations regissant les matrices de correlation est exprimee en fonction des valeurs et matrices propres de l'operateur de transport pour un reacteur sous-critique et de puissance nulle. Ceci permet de definir, en chaque point du reacteur et pour des detecteurs repondant a des neutrons de vitesse definie, des fonctions de correlation et de transfert dont les entrees sont attaquees par une meme source de bruit blanc. Le role joue par l'operateur importance, adjoint de l'operateur de transport, est aussi precise. (auteur)

  8. Essay Genre in Tatar Journalism

    2017-11-01

    Full Text Available In this article, an essay is considered as a journalistic genre in the context of modern Tatar journalism. Using the example of works by contemporary authors in the Tatar-speaking periodicals of Russia, the main genre and the semantic features of this genre are studied. An essay is a publicistic form to reflect on the topical issues of Russian reality. The reproduction of a fact is not so important for an essay. An important role is played by the description of the author's impressions, reflections and emotions. The periodical press has many materials in the Tatar language in which the author's opinion, author's principle and subjective opinion are strongly expressed. In fact, during the last decades of the twentieth century and the beginning of the twenty-first century there was a surge of essays in modern journalism. Due to some political events in Russia during the early 90s of the twentieth century, it was possible to express their thoughts and speak on the urgent problems in society openly in comparison with the Soviet reality. The object of research is essayism as a kind of journalistic creativity, the subject of the study is the essay genre in Tatar journalism. The empirical basis of the work consisted of the essays from Tatar journalists, publicists and writers. Provided that the personality of an author is one of the effectiveness factors concerning the publications in the genre of essay, the essayization of texts in Tatar journalism will be increased in the future.

  15. The genre of everyday life

    2012-01-01

    Full Text Available The present essay shows the new genres of the seventeenth century Dutch painting (portrait, landscape and genre painting, viewed as painting of everyday life, as an alternative proposition to the historical painting then dominant in the academic categorization. What used to be marginal, peripheral and of secondary importance became the main motif in the majority of Dutch painting. Minor genres came to prominence and acquired autonomous status. The interest in the elements of everyday life could be traced in European art earlier but it was the seventeenth century Dutch artists that ultimately led “low” and realistic subject themes to come into their own commercially and artistically. Occasionally, even religious themes were presented as genre scenes, thus introducing to the presented images an air of ambivalence. In the works of Dutch painters, the uniqueness of high subject themes was opposed by pictures of everyday life and the repetitiveness of everyday domestic activities, not shunning, however, the allegorical potential contained in some of the depictions.

  19. BYLINA AS A LITERARY GENRE

    Directory of Open Access Journals (Sweden)

    Olga V. Zakharova

    2015-11-01

    Full Text Available The bylina is a Russian epic song about the bogatyrs. Diff erent genre transformations of bylinas are known in folklore: prosaic narrations [pobyval’shchiny], bogatyr tales, legends about the bogatyrs, lubok tales about the feats of the bogatyrs and knights. In the early 19th  century, Russian literature was actively absorbing epic images and motives: the bogatyrs were turning into characters of novellas, literary tales, poems, novels, operas. Some poets and writers were attempting to develop the bylina as a literary genre. Their genre search was a  creative imitation of Th e Tale of Igor’s Campaign [“Slovo o polku Igoreve”] published in 1800 and in some cases of the Collection of Kirsha Danilov (1804. One of the first attempts was Gavrila R. Derzhavin’s work Dobrynya, Dramatic Musical Performance in Five Acts [“Dobrynya, teatral’noe predstavlenie s muzykoyu, v pyati deystviyakh”, 1804]. Glorifying the idea of the state, the poet composes a work where epic and literary characters act and the plot is derived not only from bylinas and tales, but also from chivalric novels. In Stepan S. Andreev’s poem Levsil, a Russian Bogatyr [“Levsil, russkiy bogatyr’”, 1807] the hero is not only a folkloric (epic and fabulous character, but also a literary one. Alexander F. Veltman’s novel Koshchei the Immortal. A Bylina of the Old Times [“Koshchey bessmertnyy. Bylina starogo vremeni”, 1833] was an ingenious genre experiment. The word ‘bylina’ was used in its title in  the literary genre meaning for the fi rst time ever. The genre of Easter novella Ilya Muromets. A Tale from the Rus’ of the Bogatyrs [“Il’ya Muromets. Skazka Rusi bogatyrskyi”, 1836] by Vladimir I. Dahl emerged from a complicated interaction of the tale, the bylina, the Old Russian novella and the hagiography. The literary transformations of folkloric genre stemmed from the authors’ imaginative need to create a national and historical myth

  20. Oral genres, argumentation and teaching

    Directory of Open Access Journals (Sweden)

    Zilda G. O. Aquino

    2015-02-01

    Full Text Available This paper aims at dealing with issues related to language spoken in the classroom, focusing on discursive practices that highlight argumentation. We believe that the discussions that were made around genres, especially guided by the studies of Bakhtin and Text Linguistics, have been providing a breakthrough towards the necessity for the school to promote language teaching through the discursive genre approach. That is what we expect to be happening since both writing and spoken modalities deserve space in learning. We believe that oral genres demand that teachers acquire specific knowledge of the features of spoken language interaction that arise from its use in practical situations. Because these studies are recent among our researchers (not longer than three decades, they should still be very present in our discussions. In this paper, we focus on a specific genre of oral tradition – the debate. It is ideal for knowledge building and taking a stand at issues that arise in society, all of which is particularly important to the school. Besides contributing to the development of skills required by certain sociodiscursive practices, it is proposed that the teaching of argumentation in oral genres concentrate on the observation of selected strategies in interactions. We are particularly interested in interactions that emerge when one interaction party is trying to persuade the other. The corpus consists of the transcriptions of debates which occurred both in the classroom and in other contexts, such as the media. The methodological approach is done by identifying the arguments and their strategic use in specific situations. The theoretical discussion rests on the works of Orecchioni (2010, Marcuschi (2004, Dolz and Schneuwly (2004, Perelman and Olbrechts-Tyteca (1996 [1958], among others.

The disposition of the fuel can also be recorded accurately by using a panoramic technique. The use of colour radiography is also discussed. Pins are normally tested for leakage after filling with helium, using a mass-spectrometer leak detector. Pins not filled with helium may be tested using a ''back-pressurizing'' technique. Conventional ''probing'' and ''sniffing'' methods are used when it is desirable to locate the sites of leaks. The bubble test in liquids is also used, as a cheap and simple test.

    One of the methods of producing carrier free phosphorus-32 today is by extraction into water from pile-irradiated sulphur. The present work gives information concerning the chemical states of P{sup 32} in aqueous solutions at different steps of the routine production-process. The variation in the chemical state of P{sup 32} compounds in the final product has also been examined as a function of storage time. P{sup 32} bound as orthophosphate was found to be the main component. During the chemical processing, the amount of orthophosphate increased from about 70% at the beginning of the extraction to about 98 % in the final carrier-free P{sup 32} product. The residual amount consisted of a mixture of pyro-, tri-, tetra-, and other long-chain polyphosphates (number of P {>=} 5). No metaphosphates (ring-formed) were found in the solutions during production and storage. The results indicate that the polyphosphorus compounds were formed in the target material during irradiation. Special attention was paid to the adsorption of carrier-free P{sup 32} compounds to glassware under the existing experimental conditions.

  4. Narrative versus Style: Effect of Genre Typical Events versus Genre Typical Filmic Realizations on Film Viewers' Genre Recognition

    OpenAIRE

    Visch, V.; Tan, E.

    2008-01-01

    This study investigated whether film viewers recognize four basic genres (comic, drama, action and nonfiction) on the basis of genre-typical event cues or of genretypical filmic realization cues of events. Event cues are similar to the narrative content of a film sequence, while filmic realization cues are similar to stylistic surface cues of a film sequence. It was predicted that genre recognition of short film fragments is cued more by filmic realization cues than by event cues. The results...

    In a nuclear reactor including the bars or plates cooled by a gaseous fluid, burst risks to occur in the sheath assuring the tightness separation between the cooling gas and the fissile materials. It is necessary to be able to detect the formation of these cracks as possible in order to avoid all risk of fission products release or any reaction of uranium to the contact of the refrigerating gas. It is however the increase of the radioactivity in the cooling gas due to the scattering of the fission products that permits to signal the apparition of a crack or to follow its evolution. It is possible to detect cracks of the order of the square millimeter. In this report, we will detail the principle and the realization of a device used for the surveillance of a natural uranium reactor cooled by air circulation. (M.B.) [French] Dans un reacteur nucleaire comportant des barres ou des plaques refroidies par un fluide gazeux des fissures risquent de se produire dans les gaines assurant la separation etanche entre le gaz de refroidissement et les materiaux fissiles. II est necessaire de pouvoir detecter la formation de ces fissures des que possible afin d'eviter tout risque de liberation de produits de fission ou de reaction de l'uranium au contact du gaz refrigerant. C'est cependant l'augmentation de la radioactivite du gaz de refroidissement due a la dispersion des produits de fission qui permet de signaler l'apparition d'une fissure ou de suivre son evolution. On peut ainsi detecter des fissures de l'ordre du millimetre carre. Dans ce rapport, nous detaillerons le principe et la realisation d'un appareil utilise pour la surveillance d'un reacteur a uranium naturel refroidi par circulation d'air. (M.B.)

    Experience of the CEA heavy water reactors and a systematic study of the radiolytic decomposition of water in the core of swimming-pool reactors are described. Setting up of reactivity control by physico-chemical methods. Reactivity control by homogeneous poisoning of the reactor A comparison of the evolution of xenon poisoning with the residual anti reactivity of the poison in solution during its nuclear consumption establishes the programme which must govern the variation in its concentration if the exact compensation is to be produced The behaviour of the poison towards the reactor materials under the particular operational conditions must be taken into account. Radiolytic decomposition of water in the reactors in the presence of soluble poisons: A study of the effect of certain chemically inert salts, present in small concentrations in the water, on its radiolytic decomposition rate, has led to some new results which are discussed. The choice of a soluble poison is justified on the basis of the above results. Reactivity control by the use of a gaseous absorbent The use of a gas control rod circuit for compensation purposes, in place of solid control rods is described. The use of soluble poisons in the moderator to compensate the xenon effect, and of a gaseous absorbent in a circuit known as a gas control rod form original aspects of the reactivity control in the reactor EL 4.

    2017-11-01

    In partnership with the largest teachers' union confederation in Québec ( Centrale des syndicats du Québec), two qualitative research studies that integrate gender were conducted in the teaching community. These ergonomic studies advocated a participatory approach involving interviews and observations with high school teachers (thirty-five) and female teachers responsible for vocational training in trades with predominantly male clientele (twelve). The results revealed that gender influences work success by reducing the operational leeway available for female teachers to carry out their work and protect their health. In both studies, it was difficult to discuss these results with the teachers, especially with female teachers. Resistance, even denial, was present among high school teachers, while, in vocational training, resignation and a feeling of helplessness were observed. These reactions demonstrate that taking gender into account in prevention poses particular challenges that need to be addressed in order to promote equality between women and men in workplaces.

    We re-implement and test two state-of-the-art systems for automatic music genre classification; but unlike past works in this area, we look closer than ever before at their behavior. First, we look at specific instances where each system consistently applies the same wrong label across multiple...... trials of cross-validation. Second, we test the robustness of each system to spectral equalization. Finally, we test how well human subjects recognize the genres of music excerpts composed by each system to be highly genre representative. Our results suggest that neither high-performing system has...... a capacity to recognize music genre....

    Abstract             Music genre is getting complex from time to time. As the size of digital media grows along with amount of data, manual search of digital audio files according to its genre is considered impractical and inefficient; therefore a classification mechanism is needed to improve searching.             Zero Crossing Rate (ZCR, Average Energy (E and Silent Ratio (SR are a few of features that can be extracted from digital audio files to classify its genre. This research conducted to classify digital audio (songs into 12 genres: Ballad, Blues, Classic, Harmony, Hip Hop, Jazz, Keroncong, Latin, Pop, Electronic, Reggae and Rock using above mentioned features, extracted from WAV audio files. Classification is performed several times using selected 3, 6, 9 and 12 genres respectively.             The result shows that classification of 3 music genres (Ballad, Blues, Classic has the highest accuracy (96.67%, followed by 6 genres (Ballad, Blues, Classic, Harmony, Hip Hop, Jazz with 70%, and 9 genres (Ballad, Blues, Classic, Harmony, Hip Hop, Jazz, Keroncong, Latin, Pop with 53.33% accuracy. Classification of all 12 music genres yields the lowest accuracy of 33.33%.    Keywords— Zero Crossing Rate (ZCR, Average Energy (E, Silent Ratio (SR, Euclidean Distance

    Full Text Available We present a new approach to defining film genre based on implicit ideals. When viewers rate the likability of a film, they indirectly express their ideal of what a film should be. Across six studies we investigate the category structure that emerges from likability ratings and the category structure that emerges from the features of film. We further compare these data-driven category structures with human annotated film genres. We conclude that film genres are structured more around ideals than around features of film. This finding lends experimental support to the notion that film genres are set of shifting, fuzzy, and highly contextualized psychological categories.

In this method, the probability to count one, two,.... neutrons during a given time is measured. The value of {alpha} can be deduced from this measurement, for various subcritical states of the reactor. The experimental results were then compared with values obtained, for the same reactivities, by the pulsed neutron technique.

    Full Text Available I provide an overview of approaches to writing referred to as 'academic literacies' building on broader traditions, such as New Literacy Studies, and I draw out the relevance of such traditions for the ways in which lecturers provide support to their students with regard to the writing requirements of the University. I offer three case studies of the application of academic literacies approaches to programmes concerned with supporting student writing, in the UK and the USA. I briefly conclude by asking how far these accounts and this work can be seen to bring together many of the themes raised at SIGET conferences - including academic literacies and its relation to genre theories - and express the hope that it opens up trajectories for future research and collaboration of the kind they were founded to develop.

A number of such instruments have been built and their response to mono-kinetic and reactor neutrons has been investigated. Use of the gamma-ray rejection technique was equivalent to a several hundred-fold effective reduction in gamma-ray sensitivity of the recoil counter and extends the usable range down to at least 30 keV. For the Li{sup 6} solid-state devices, resolutions as low as 70 keV full-width at half maximum (1.5%) have been observed for the sum pulse in thermal neutron irradiation.

    Barbedo, Jayme Garcia sArnal; Lopes, Amauri

    2006-12-01

    We present a strategy to perform automatic genre classification of musical signals. The technique divides the signals into 21.3 milliseconds frames, from which 4 features are extracted. The values of each feature are treated over 1-second analysis segments. Some statistical results of the features along each analysis segment are used to determine a vector of summary features that characterizes the respective segment. Next, a classification procedure uses those vectors to differentiate between genres. The classification procedure has two main characteristics: (1) a very wide and deep taxonomy, which allows a very meticulous comparison between different genres, and (2) a wide pairwise comparison of genres, which allows emphasizing the differences between each pair of genres. The procedure points out the genre that best fits the characteristics of each segment. The final classification of the signal is given by the genre that appears more times along all signal segments. The approach has shown very good accuracy even for the lowest layers of the hierarchical structure.

  15. Genre, technology and embodied interaction: The evolution of digital game genres and motion gaming

    Directory of Open Access Journals (Sweden)

    Andreas Gregersen

    2011-11-01

    Full Text Available Technology has been given relatively little attention in genre theory, but this article argues that material technologies can be important components in genre development. The argument is based on a historically informed analysis of digital games, with special attention paid to home console video games and recent genre developments within this domain commonly referred to as motion gaming. The main point is that digital game genres imply structured embodied activity. A constitutive element of digital game mediation is a control interface geared to player embodiment, and I propose the concept of ‘interaction modes’ to describe the coupling of technology and player embodiment and show how this can be integrated with genre theory. The resulting framework allows for increased attention to continuity and change in game and communication genres, material and digital technologies, and the related interaction modes.

    The article discusses humorous conversational activities (e.g. jokes, teasing, joint fantasizing) in the context of genre theory. The high degree of creativity, emergent construction and artistry typical of humor call for a flexible concept of genre which makes sense of modifications and transgressions in communicative processes. Some forms of conversational humor are generic, for example, standardized jokes, joint fantasizing or teasing. Other forms exploit our knowledge of serious genres an...

    We propose a video genre classification method using multimodal features. The proposed method is applied for the preprocessing of automatic video summarization or the retrieval and classification of broadcasting video contents. Through a statistical analysis of low-level and middle-level audio-visual features in video, the proposed method can achieve good performance in classifying several broadcasting genres such as cartoon, drama, music video, news, and sports. In this paper, we adopt MPEG-7 audio-visual descriptors as multimodal features of video contents and evaluate the performance of the classification by feeding the features into a decision tree-based classifier which is trained by CART. The experimental results show that the proposed method can recognize several broadcasting video genres with a high accuracy and the classification performance with multimodal features is superior to the one with unimodal features in the genre classification.

    This apparatus is designed to measure instantaneously the positive or negative reactivity of a uranium reactor moderated by light water, on condition that the point of departure is the critical state of the reactor, or an already known sub-critical state. Slight modifications only are required to adapt it to another type of reactor. It is an analogue computer which simply inverses the transfer function of the reactor; it is not therefore a model reactor of which the output voltage is connected by a servo-mechanism to the power of the reactor to give the reactivity; the principle of the calculation of the reactivity does not depend on a servomechanism. One of its disadvantages is that it cannot operate outside a power variation range of 2.5 decades. However the measurement of a negative reactivity value between 0 and 3000 pcm is immediate. It measures the reactivity without deducting it from the period; it therefore gives the reactivity very precisely both for divergence and convergence even through in this latter case the period does not in fact exist. The equipment makes it possible to calibrate very rapidly the control rods of a reactor (the rod-drop method), to measure the reactivity of an experiment in the core, and to measure certain temperature effects. It is also possible by introducing a control into the core at a measured rate, to deduce directly its efficiency curve.

Ce reacteur est utilise comme source puisee de neutrons pour les experiences de physique fondees sur la methode du temps de vol. On l'emploie pour etablir la section efficace totale et la section efficace de capture des neutrons intermediaires, pour etudier l'interaction des neutrons lents et des corps solides ou liquides et pour mesurer les spectres neutroniques dans differents milieux. Le memoire decrit les caracteristique s essentielles de la construction du reacteur et les resultats d'experiences faites a l'aide de ce reacteur. Le regime de fonctionnemen t normal est celui des impulsions periodiques. Les impulsions de puissance sont produites par un deplacement rapide de la partie mobile du coeur a travers sa partie immobile. La partie mobile se trouve fixee sur un disque tournant et se deplace a une vitesse d'environ 230 m/s. Une zone mobile auxiliaire permet de modifier la frequence des impulsions de puissance entre 2,3 et 88 ips. Le reacteur a une puissance moyenne de 1 kW. La demi-largeur d'une impulsion de puissance est de 36 {mu}/s. Le reacteur est dote d'un systeme de commande et de securite qui assure le maintien automatique de la puissance moyenne et un arret rapide en cas de fonctionnement irregulier. Il est equipe d'un systeme de canalisations sous vide pour le passage des neutrons, qui permettent de mesurer le temps de vol. Le canal principal a 1000 m de long. Lors du demarrage du reacteur et durant les experiences de physique dont il a fait l'objet, on a etudie l'effet que produit sur la reactivite le deplacement des organes de commande et des parties mobiles du coeur; on a mesure la longueur des impulsions a des regimes de fonctionnement differents et etudie les fluctuations d'amplitude des impulsions de puissance.

Ces specifications sont etablies d'apres les taux de dose consideres comme admissibles pour les populations vivant aux environs de la centrale en cas d 'accident grave du reacteur, en se basant sur des conditions meteorologiques et demographiques representatives de la plupart des sites du pays. Differents modes de construction de l ' enceinte de confinement, prenant en consideration les conditions qui s'etablissent dans l'enceinte a la suite de l'accident maximal concevable du reacteur, sont consideres. Les enceintes etudiees sont les suivantes: beton precontraint; beton precontraint avec coupole d'acier; beton precontraint avec peau d' etancheite interieure en acier; acier avec ecran lateral en beton pour la protection contre les radiations; et double confinement. Le degre d'etancheite des enceintes etudiees a ete considere comme une caracteristique lie e au mode de construction particulier et non comme une valeur prescrite en vue de laquelle la construction devait etre adaptee.

    The aim of this study is to develop techniques to qualify the efficiency of liquid distribution in trickle-bed reactors, using cold mockups. The experimental setup consists mainly in a 0.3-m-ID packed-bed column with three different plates used to vary the quality of inlet liquid distribution. Liquid distribution has been qualified using several techniques: global pressure drop measurements, global RTD (Residence-Time Distribution) of the liquid, local heat transfer probes, capacitance tomography, collector at the bottom of the reactor with nine equal zones. The bed pressure drop and the overall external liquid saturation decrease when the maldistribution increases; quantitative information is however difficult to obtain this way. Global RTD of the liquid allows quantifying of the average liquid distribution in the bed. The local thermal sensors give an indication of local liquid velocity and indicate possible local maldistribution of the liquid (scale mm) even when global distribution is good. Concerning the results obtained with the collector, a maldistribution index is defined ranging from 0 (ideal distribution) to 1 (worst possible distribution), and the influence of the different operating parameters (gas and liquid velocities, particle shape) is discussed.

    Full Text Available Fiction, a prime form of entertainment, has evolved into multiple genres which one can broadly attribute to different forms of stories. In this paper, we examine the hypothesis that works of fiction can be characterised by the emotions they portray. To investigate this hypothesis, we use the work of fictions in the Project Gutenberg and we attribute basic emotional content to each individual sentence using Ekman's model. A time-smoothed version of the emotional content for each basic emotion is used to train extremely randomized trees. We show through 10-fold Cross-Validation that the emotional content of each work of fiction can help identify each genre with significantly higher probability than random. We also show that the most important differentiator between genre novels is fear.

The serial...... is discussed in the light of Christine Gledhill’s statement that in the new prime-time soap “melodrama and realism, women’s and men’s culture, intersect (...) in a particularly productive way”. I conclude that while it it true that the male characters in “Taxa” are multi-dimensional personalities, women...... in this Danish soap opera are not only almost absent as writers and directors, but the female figures are also highly mythologized. Thus the costs of the soap genre going mainstream are marginalization and trivialization of women....

    In a heavy-water moderated reactor cooled by pressurized gas, an important problem from the point of view, of the reactor block and its economics is the choice of the gas supply system. In the pressure tube solution, the whole of the reactor block structure is at a relatively low temperature, whereas the gas supply equipment is at that of the gas, which is much higher. These parts, through which passes the heat carrying fluid have to present as low a resistance as possible to it so as to avoid costly extra blowing power. Finally, they may only be placed in the reactor block after it has been built; the time required for putting them in position should therefore not be too long. The work reported here concerns the various problems arising in the case of each channel being supplied individually by a tube at the entry and the exit which is connected to a main circuit made up of large size collectors. This individual tubing is sufficiently flexible to absorb the differential expansion and the movement of its ends without stresses or prohibitive reactions being produced; the tubing is also of relatively short length so as to reduce the pressure head of the pressurized gas outside the channels; the small amount of space taken up by the tubing makes it possible to assemble it in a manner which is satisfactory from the point of view both of the time required and of the technical quality. (authors) [French] Dans un reacteur modere a l'eau lourde et refroidi au gaz sous pression, un probleme important du point de vue du trace du bloc pile et de son economie est le choix du systeme d'alimentation en gaz. Pour une solution a tubes de force, l'ensemble des structures du bloc reacteur est a temperature relativement faible, alors que les organes d'alimentation en gaz sont a celle, notablement plus elevee, du gaz.

  8. "Emotions-Only" versus "Special People": Genre in fan discourse

    Directory of Open Access Journals (Sweden)

    Louisa Ellen Stein

    2008-09-01

    Full Text Available This essay looks at genre as a complex set of discursive threads running unevenly through production, TV text, and fan reception. Through a case study of the reception of fan favorite Roswell, this essay interrogates the role of genre in spectatorship. In its mixing of teen and science fiction elements, Roswell trod upon contested generic spaces, eliciting strong reaction from its viewers. Connections between genre and gender came to the fore, as producer commentary linked science fiction with male audiences and teen romance with female audiences. Fans responded with analyses that greatly complicated and at times overtly rejected industrial suppositions regarding the gendered work of genre. Through these fan conversations, we can witness the complexity of genre as discursive thread moving through not only TV texts but also multivariant fan responses. I intend this essay to work at two levels. My analysis of fan responses to Roswell models the possibilities of a close study of genre discourse. At the same time, my case study probes the nature of genre in fan engagement, as genre discourses intersect with other fan concerns such as character identification, perceptions of textual quality, and questions of gender representation. While we cannot necessarily look to fan accounts for proof of how viewers engage with genre, they do tell us how fans frame their engagement with genre, how they incorporate genre into their performance of fannishness, and how they perform and thus enact genre itself as a shared cultural process.

    2010-01-01

    Full Text Available On emploie souvent aujourd’hui les termes « artiste » et « plasticien » comme synonymes. Sous cette simple manière de parler se dit une vérité troublante et profonde. Troublante, car la plasticité associe l’activité de la création d’une forme (la plastikê des Grecs à la nécessaire destruction (le plasticage de la forme initiale, de sorte que, si l’art est plastique, il est essentiellement lié à la perturbation et la transgression. Profonde, car cette plasticité ne serait pas le propre de notre modernité, et encore moins une idée relevant d’une mode intellectuelle passagère, mais l’essence intime de l’art à travers toute son histoire. On a voulu suggérer cela, en proposant le néologisme du « dianouménal » pour qualifier cette plasticité, et en remontant à l’art des cavernes pour en voir l’effectivité dès l’origine. Au Paléolithique, en effet, les Vénus gravettiennes par leur plastique androgyne sèment d’emblée le trouble dans le genre.

Formal and thematic features play a far too significant role in literary works to be explicable simply as derivations from function alone. But this is not limited...... to formal and thematic interpretations of genre, by allowing the utterances themselves to re-enter center stage. This enables an improved understanding of complex genres. It also revives close reading as a viable approach to understanding genre and thus to inform the rhetorical, linguistic, and sociological...

  16. Exploring different approaches for music genre classification

    Directory of Open Access Journals (Sweden)

    Antonio Jose Homsi Goulart

    2012-07-01

    Full Text Available In this letter, we present different approaches for music genre classification. The proposed techniques, which are composed of a feature extraction stage followed by a classification procedure, explore both the variations of parameters used as input and the classifier architecture. Tests were carried out with three styles of music, namely blues, classical, and lounge, which are considered informally by some musicians as being “big dividers” among music genres, showing the efficacy of the proposed algorithms and establishing a relationship between the relevance of each set of parameters for each music style and each classifier. In contrast to other works, entropies and fractal dimensions are the features adopted for the classifications.

  17. Functions of Narrative Genres for Lived Religion

    Directory of Open Access Journals (Sweden)

    Tuija Hovi

    2014-05-01

    Full Text Available The article presents the object and results of a study which combines the psychology of religion and folkloristics in the form of a qualitative analysis of empirical ethnographic material compiled from sources in a local neo-charismatic congregation called the ‘Word of Life’. Personal narrative is discussed as a genre which represents the collective tradition of a religious community. It is a socially-learned speech act and a means of interpreting and sharing religious experience, thus constructing and confirming the faith of the community, both individually and collectively. In the neo-charismatic tradition, everyday speech draws on a literal (biblical tradition as well as on socially-shared narrative genres such as ritual testimonies, prophecies, sermons and casual, personal narratives of co-believers. The faith-creative power of these stories can be found in their performative utterances and evaluative structures as well as in non-communication.

(author) [French] Aux centres crees autour des deux, reacteurs de recherche suedois, Rl a Stockholm et R2 a Studsvik, on a maintenant la possibilite d'utiliser quatre spectrometres differents pour les experiences de diffusion inelastique des neutrons. A Stockholm, le reacteur Rl de 600 kW, ralenti a l'eau lourde, est equipe de deux spectrometres mecaniques a neutrons lents qui fonctionnent simultanement, Avec l'un, on utilise toujours un monochromateur a filtre en Be; avec l'autre, on peut employer soit le meme genre de monochromateur, soit un monochromateur a cristal. On a constate que pour les mesures de distribution angulaire, on obtient d'excellents resultats en combinant un monochromateur a cristal et un spectrometre mecanique, meme si l'intensite et le pouvoir de resolution sont relativement faibles. Recemment on a fait l'essai d'un selecteur de vitesse mecanique ayant un pouvoir de separation des longueurs d'onde de 4,2%. Cependant, cet instrument n'est pas encore utilise pour les experiences. Le spectrometre mecanique de Studsvik, avec lequel le reacteur R2 de 30 MW ralenti a l'eau legere est equipe, utilise pour la monochromatisation l'action combinee d'un monochromateur a filtre de Be et d'un hacheur a courbe de transmission etroite. Dans ce spectrometre, de meme que dans celui de Stockholm, le hacheur est place avant l'echantillon, ce qui permet l'enregistrement simultane de donnees pour des angles d'observation differents. Un spectrometre a cristal triaxial est aussi en service pres du reacteur R2. Les auteurs donnent certaines caracteristiques de ces instruments, notamment l'intensite, le pouvoir de resolution, et indiquent dans quelle mesure ils conviennent pour certaines operations.

    the fact that the thorium is dispersed in graphite and the usual cadmium-ratio technique is difficult to apply. Comparison of experimental and theoretical results shows excellent agreement over a range of variables. In addition, the results of both activation and reactivity measurements of Doppler coefficient are in agreement, a fact which is felt to be significant in view of the disparity between results from these two techniques in the literature.

Aux fins de l'etude nucleaire theorique, les besoins particuliers en donnees d'entree relatives aux absorptions par le thorium ont amene les ingenieurs a concevoir un assemblage experimental critique compose d'un reseau central entoure d*une region tampon et d'une region de commande.

    Full Text Available This paper analyzes the terminology in the Internet social networks tutorials. A tutorial is a specialized text, full of terms, aiming to teach an individual or group of individuals who need some guidelines to operationalize a computerized tool, such as a social network. It is necessary to identify linguistic and terminological characteristics from the specialized lexical units in this digital genre. Social networks terminology is described and exemplified here. The results show that it is possible to refer to two specific terminologies in tutorials which help to determine the terminological profile of the thematic area, specifically from the point of view of denomination.

    Full Text Available Neste painel, discutimos a relação 'letramento' e 'gênero textual', considerando a rica complexidade que envolve não apenas esses objetos teóricos mas também a sua aplicação no domínio pedagógico, particularmente no que diz respeito ao ensino-aprendizagem de língua materna. Vincularemos a discussão a nossa experiência de ensino, pesquisa e extensão desenvolvida em programas de formação de professores, voltados para a mobilização de práticas transdisciplinares de natureza colaborativa e fortalecedora da ação docente. Nessa direção, indicamos os projetos de letramento como uma alternativa para o desenvolvimento de um trabalho contextualizado com os gêneros textuais.Our contribution to this panel intends to discuss how 'literacy' and 'genres' are related, taking into account the complexity involving not only these two theoretical concepts, but also their implementation in the pedagogical domain, especially related to mother tongue learning-teaching. We intend to discuss that based on our experience in teaching, research and extension developed at teacher education programs aiming at transdisciplinary practices of colaborative and strengthening nature. To accomplish this task, we suggest literacy projects as an alternative to develop a contextualized work with genres.

  15. A new detector for the measurement of neutron flux in nuclear reactors; Nouvelle methode de mesure des flux de neutrons dans les reacteurs atomiques

    The detector described is designed for the instantaneous measurement of thermal neutron fluxes, in the presence of high {gamma} ray activity; this detector can withstand temperatures as high as 500 deg. C. It is based on the following principle: radioactive atoms resulting from heavy-nucleus fission are carried by a gas flow to a detector recording their {beta} and {gamma} disintegration. Thermal neutron fluxes as low as few neutrons per cm{sup 2} per second can be measured. This detector may be used to control a nuclear reactor, to plot the thermal flux distribution with an excellent definition (1 mm{sup 2}) for fluxes higher than 10{sup 8} n/cm{sup 2}/s. The time response of the system to a sharp variation of flux is limited, in case of large fluxes, to the transit time of the gas flow between the fission product emitter and the detector; of the order of one tenth of a sec per meter of piping. The detector may also be applied for spectroscopy of fission products eider than 0,1 s. (author)Fren. [French] On decrit un appareil permettant la mesure instantanee des flux de neutrons thermiques accompagnes de flux intenses de rayons {gamma} et situes dans des enceintes pouvant etre portees a des temperatures superieures a 500 deg. C. On utilise la radioactivite des atomes resultant de la fission des noyaux lourds; ces atomes sont entraines par un courant gazeux vers un detecteur de radioactivite qui enregistre leurs desintegrations {beta} et {gamma}. On peut mesurer des flux partir de quelques neutrons thermiques par cm{sup 2} et par seconde. L'appareil permet de suivre la puissance d'un reacteur atomique, de tracer des cartes de densite de neutrons avec une tres bonne definition (1 mm{sup 2}) dans le cas de flux superieurs a 10{sup 8} cm{sup 2}/s. Le temps de reponse du systeme a une variation du flux de neutrons est limite, poes flux importants, par le temps de transit du gaz entre l'emetteur de produits de fission et le detecteur: soit quelques dizaines de

    Full Text Available How do opinion, discussion, and argumentative convince readers? How does each of them look different each other seen from the generic structure, and language use? This conceptual paper is exploring how three selected genres in academic writing differ from each other. By reviewing journal of related topic of recently published, the writer convinces that opinion genre is less strong in persuading readers, and argumentative is very strong in assuring readers, whereas discussion is neutral in affecting readers The implication is that each genre has its own place to make readers satisfied and each of which indicates the level of ego and sophisticated countering back the statement called rebuttal and arguments and example. By reading this article readers will detect the tone of each genre and to what extent does each genre reach the readers’ mind. The implication is that any teacher or lecturer is best recommended to present this model, particularly in EFL context.

    Full Text Available The emergence of exploring genre analysis has been a trend in Applied Linguistics, not only for its interesting factor, but also because of its pedagogical implications. This study aimed to determine the overall structure, specifically the presence and conformity of moves and steps of the research introductions in the field of Linguistics. Twelve (12 available research introductions were analyzed using Create-A-Research-Space (CARS model. The findings revealed that moves and steps across the research introductions are present. Majority of the research introductions conformed to the CARS model, but did not necessarily follow the suggested sequence. Results imply that teachers of research writing should acknowledge and introduce the CARS model as a basis for teaching the method of writing research introductions effectively.

  6. Music genre classification using temporal domain features

    2004-10-01

    Music genre provides an efficient way to index songs in the music database, and can be used as an effective means to retrieval music of a similar type, i.e. content-based music retrieval. In addition to other features, the temporal domain features of a music signal are exploited so as to increase the classification rate in this research. Three temporal techniques are examined in depth. First, the hidden Markov model (HMM) is used to emulate the time-varying properties of music signals. Second, to further increase the classification rate, we propose another feature set that focuses on the residual part of music signals. Third, the overall classification rate is enhanced by classifying smaller segments from a test material individually and making decision via majority voting. Experimental results are given to demonstrate the performance of the proposed techniques.

The burn-out flux following uniform 'stopped' heating has been studied in a channel containing still water. The flux shows a maximum as a function of unsaturation. The influence of the geometry and the nature of the metal was investigated. 4 - Output Oscillations: Using a low pressure (8 atm) loop, the influence of various parameters on the periods of output oscillations in a boiling channel on the thresholds at which they appear, was studied. Some new aspects of this complex phenomena were observed and are reported. (authors) [French] On indique les principaux resultats obtenus a Grenoble depuis quatre ans dans le domaine des mecanismes de l'ebullition et des phenomenes connexes dans les reacteurs nucleaires. 1 - OBSERVATION DE L'EBULLITION: Par photographie et cinematographie ultrarapide (8000 images par seconde maximum) on a observe l'ebullition en vase ou en canal jusqu'a 140 kg/cm{sup 2}. On a denombre les populations de germes (sites) generateurs de bulles et obtenu une correlation donnant leur nombre par unite de surface en fonction du flux thermique et de la pression. Le diametre des bulles se detachant de la paroi a ete etudie jusqu'a 140 kg/cm{sup 2}. On a mis en evidence trois types de bulles: - Les bulles en equilibre dont le diametre suit la formule de Fritz et Ende, - Les bulles d'ebullition dont le diametre diminue rapidement avec la pression (1/100 mm a 140 kg/cm{sup 2}), - Les coalescences apparaissant en liquide sature au-dessus de 15 W/cm{sup 2} et dont la proportion est independante de la pression. Par visualisation en strioscopie on observe les mouvements du film thermique associes a l'amorcage des germes, au depart et a la condensation des bulles; les mecanismes responsables de l'excellent transfert de chaleur ont pu ainsi etre precises. 2 - PERTES DE PRESSION EN ECOULEMENT DIPHASE: On a etabli un modele de variation continue du taux de vide dans un canal

    2017-01-01

    Based on a large behavioral dataset of music downloads, two analyses investigate whether the acoustic features of listeners' preferred musical genres influence their choice of tracks within non-preferred, secondary musical styles. Analysis 1 identifies feature distributions for pairs of genre-defined subgroups that are distinct. Using correlation analysis, these distributions are used to test the degree of similarity between subgroups' main genres and the other music within their download collections. Analysis 2 explores the issue of main-to-secondary genre influence through the production of 10 feature-influence matrices, one per acoustic feature, in which cell values indicate the percentage change in features for genres and subgroups compared to overall population averages. In total, 10 acoustic features and 10 genre-defined subgroups are explored within the two analyses. Results strongly indicate that the acoustic features of people's main genres influence the tracks they download within non-preferred, secondary musical styles. The nature of this influence and its possible actuating mechanisms are discussed with respect to research on musical preference, personality, and statistical learning.

    'un reacteur et celui de certains circuits radioelectriques usuels. Les fluctuations peuvent alors etre calculees par l'introduction dans le circuit d'une source de bruit convenable. Cette methode nous a permis d'aborder sous une forme particulierement simple l'etude des fluctuations d'ensemble et de preciser la signification physique de certains resultats auxquels conduisent plus laborieusement les autres methodes. L'objet du present rapport est de generaliser cette methode,notamment de l'etendre au cas d'un reacteur ayant une structure en cellules et de l'appliquer a l'etude des fluctuations dans une cellule. On etablit ainsi simplement que les fluctuations dans une cellule sont la resultante de deux termes: - un bruit poissonnien a evolution rapide, non correle avec les fluctuations d'ensemble ; - un bruit a evolution lente, lorsque le reacteur n'est pas trop eloigne de la criticalite, correle avec les fluctuations d'ensemble. Le premier terme provient d'une 'mise en ordre' rapide du systeme, au cours de laquelle les cellules se mettent en equilibre entre elles. Le deuxieme terme traduit l'evolution coordonnee de l'ensemble des cellules, apres extinction de la premiere phase transitoire. Les conclusions de l'etude montrent qu'il serait utile de la completer par une analyse des phenomenes non lineaires qui peuvent influer considerablement sur le comportement transitoire des cellules, pendant la phase ou elles tendent a se mettre en equilibre entre elles. Ce rapport met aussi l'accent sur les liens entre la nouvelle methode et les methodes anterieures. De plus, il tend a faire entrer la theorie des fluctuations des piles dans un cadre plus general, celui des fluctuations d'un systeme dependant de plusieurs parametres aleatoires, et de ce point de vue, la methode pourrait etre aisement transposee et adaptee a l'etude d'autres problemes physiques de ce type.

    Full Text Available With this work we actualize the problem of application of journalistic genres in contemporary production of the press, radio, television and new media. We provide an overview of the different uses of journalistic genres in contemporary media, including identifying deviations and declination from the standardized norms for writing certain journalistic genres. We start from the premise that journalistic forms / shapes grouped into functional genres and, as such, represent the linguistic, narrative and discursive basis of each media. By this way we base our argument on the necessity of the existence of the necessary level of conventionality and standards setting writing techniques and construction of journalistic genres with the aim to preserve and improve the overall media discourse, language standard and increase the informativeness of the media as the most important communicative value and function. In this paper we point out the most common forms of deviation and destruction of some forms / shapes within the genres of contemporary journalism practice. The deviations we see as opportunity to improve the function of the journalistic narrative, but more often we see the danger of destruction of tissue and textual stratification of genres, forms of journalistic expression to new, hybrid and uncomplete forms that reduce the informativeness and increase ancillary or related attributes of journalistic text. In particular, we draw attention to the appearance of hybrid genres that intensify the relationship with the audience, actualize psycho-social relations and suggest value and differential categories and changes in audience behavior. The origin of the work we provide definition of layering genres and point to the potential dangers of disintegration threaten journalistic narrative. We point out potential solutions, the place and role of professional journalistic community, education institutions, science and public institutions in preventing and

    This article proposes a particular approach to video game music, advocating the usefulness of genre-based enquiry. Two generic levels are active in video game music: ‘interactive genre’ (the type of game/interactive mechanism) and ‘environmental genre’ (the ‘setting’ of the game). The interaction between these levels produces the game’s music. By examining games within the same interactive genre, even if the environmental genre is markedly different, we can begin to uncover similar concerns, ...

    We analyze web-downloaded data on people sharing their music library. By attributing to each music group usual music genres (Rock, Pop ...), and analysing correlations between music groups of different genres with percolation-idea based methods, we probe the reality of these subdivisions and construct a music genre cartography, with a tree representation. We also discuss an alternative objective way to classify music, that is based on the complex structure of the groups audience. Finally, a link is drawn with the theory of hidden variables in complex networks.

    2012-08-01

    Full Text Available Systemic Functional Linguistics is a linguistics approach which cop-siders not only the structure of the language but also its social context. In the Systemic Functional Linguistics the concept of genre is defined as a step-by-step activity to reach the goal. The concept of genre is used to describe the cultural context in a language. According to this view, text should be seen and observed in its interaction with the context and social background. For that, the genre analysis will constantly involve the linguistic social context in the forms of field, tenor, mode, schematic structure and its realization in the text.

In Persian courtesy, elegy is often versified and it may have different genres, but the most frequently used genre up to the end of 8th century is the ode, and fragment genre, Refrain and compounding are next ranks. Among Khaghani’s elegies, twenty-one elegies are composed in ode genre, sixteen of which have row and five others do not have any row.   After ode, Fragment genre has more applicability in Khaghani’s Divan in elegies. Generally, he composed nineteen Fragments about the courtier and religious men. Khaghani also composed four composite-tie about his son mourning and government’s personnel. One thing to be noticed by poet about elegy is the proportion of verse with subject. Most of prosodic verses couldn’t be used in elegy. From the beginning of Persian poetry to the end of 8th century, Ramal poetical meter (faelaton foot is the most usable and Gharib poetical metre (faoulon foot is less usable one among others. In Khaghani’s Divan Ramal poetical meter with fifteen cases, the most usable poetical meter is elegy. After future, Mozare octagonal poetical meter (mafoulo faelato mafailo faelon and khafif poetical meter (faelaton mafaelon faelon are placed next with six cases.

Although Khaghani couldn’t hide his influence from the coming event, he also does not give up imagology. According to the conducted studies, one should say that Khaghani made nice images in elegy; images followed by formality, but its amount is less than Khaghani’s other odes. Simile is presented more than other imaginations in Khaghani’s elegies. Next step belongs to

Then they enroll in university to study a profession. English for Professional Communication is usually a part of their curriculum. Within it, they need to acquire communicative competence enabling them to enter a discourse community of experts. In addition to learning the terminology used in a profession they have to acquire sociolingual and discourse competences as well including generic one. It is a challenge that English teachers face when they decide to enclose authentic genres into their teaching materials. This paper presents suggestions how written genres can be used in teaching English for nurses. Most of the discourse and genre analyses relate to face-to-face doctor-patient encounters and nurses´ computer-mediated communications. To my knowledge, less attention has been given to written genres of the nursing discourse. Therefore the paper presents the most important concepts of genre, explains the roles of genre in organizational communication and gives a brief description of the discourse community of nurses and ways it uses task-oriented and patient-oriented genres as mechanisms of interaction.It also explains the purpose of individual genres. In the process of creating materials for learning professional English one of the most important tasks is the selection of suitable texts as they should meet learners´ needs and represent texts used in practice. I consider a Nursing Care Plan for a key text. Therefore, I present a detailed analysis of its parts focused on their communicative functions, description of standardized lexis, grammar structures and broken grammar rules. I suggest a method how to teach the Nursing Care Plan genre in English lessons and present tasks leading to the acquisition of receptive

    A fundamental problem with nearly all work in music genre recognition (MGR)is that evaluation lacks validity with respect to the principal goals of MGR. This problem also occurs in the evaluation of music emotion recognition (MER). Standard approaches to evaluation, though easy to implement, do not reliably differentiate between recognizing genre or emotion from music, or by virtue of confounding factors in signals (e.g., equalization). We demonstrate such problems for evaluating an MER syste...

    This paper reviews the experience acquired in France on the question, of reactor safety. Since a special paper is being presented on reactors of the graphite gas type, the safety of the other types studied in France is discussed here: - heavy water-gas reactors, - fast neutron reactors, - water research reactors of the swimming-pool and tank types. The safety rules peculiar to the different types are explained, with emphasis on their influence on the reactor designs and on the power limits they impose. The corresponding safety studies are presented, particular stress being placed on the original work developed in these fields. Special mention is made of the experimental systems constructed for these studies: the reactor CABRI, pile loop for depressurization tests, loops outside the pile, mock-ups etc. (authors) [French] La presente communication propose une synthese de l'experience acquise en France en matiere de surete des reacteurs.

    The OECD High-Temperature Reactor Project (DRAGON) was set up to develop the technology of high-temperature gas-cooled reactors and, as part of this development, to construct and operate a 20-MW(t) reactor experiment. The reactor, which is now nearing completion, is a helium-cooled system with a coreoutlet temperature of 750{sup o}C; it employs U{sup 235} fuel with thorium as a fertile material. A particular feature of this system is the absence of any metals in the core. Because of the high temperatures involved, namely, up to 1050{sup o}C at fuel element surfaces and above, 1500{sup o}C in-the hottest regions of the fuel, refractory nonmetallic materials are employed. All the core material is incorporated within the fuel element which leads to a high ratio of heat transfer surface area to core volume and hence permits a high average power density leading to a relatively compact system. Each fuel element consists of a cluster of graphite tubes, containing the fissile and fertile materials as carbides incorporated in graphite pellets. A purge flow of the helium coolant passing through the centre of each fuel rod is extracted from the base whence it passes into a helium processing plant to remove fission products and other impurities before being returned to the reactor. This procedure reduces the escape of fission products from the very hot ceramic fuel into the primary coolant stream. Problems associated with the development and production of ceramic fuel bodies and graphite for this reactor, and the behaviour of these materials under operating conditions are outlined. Some experience from irradiation and in-pile loop investigations are reported. The main emphasis in this programme is on the development of the high-temperature gas-cooled reactor for application as an economic power producing system.

    The reactor EL2 is the second atomic reactor built in France. It is a laboratory reactor using heavy water and natural uranium. Its cooling circuit operates with compressed CO{sub 2} gas at 8 kg/cm{sup 2} pressure. The subject of this lecture is the manufacturing of the fourth set of rods. The principle of uranium-can connection is exposed: that is the principle of a pre-pressed bound can. The EL2 reactor has been a prototype with respect to this aspect of the question, and a prototype which has been quite satisfactory. The main steps of the fabrication are exposed: the {gamma} phase extension of uranium, the machining, the three canning (die canning, hydraulic canning, compressed air treatment), the automatic argon arc welding of cups and the different manufacturing controls.

    Background and aims Although Internet gaming disorder (IGD) has been investigated in detail, minimal research has been conducted regarding the influence of different game genres on IGD. The aim of this study is to compare the characteristics of members of game genre-specific groups with IGD and to identify factors associated with IGD status in each group in a large sample of adults. Methods Internet games were categorized into four genres: real-time strategy games, massive multiplayer online role-playing games (MMORPG), sport games, and first-person shooter (FPS) games. Participants (n = 2,923) who usually played one of these games completed an anonymous online survey that collected sociodemographic, game usage pattern, and psychopathological assessment data. Results MMORPG and FPS game players more frequently met the criteria for IGD than participants in the other two groups. Differences between the IGD-suspected gamers within the genre-specific groups were observed for a few items, such as average game-playing time and the subscales of the behavioral activation system; however, the factors that contributed to the development of IGD within each game genre-specific group were found to be considerably different. Discussion and conclusions The findings of this study suggest that IGD is a stable psychiatric diagnosis encompassing users of a broad range of game genres. In addition, the development of strategies for the prevention of and early intervention on individuals at high risk for developing IGD may require consideration of the distinct characteristics identified as effective predictors of IGD in users of each game genre.

    The cartridge of an internally and externally cooled annular fuel element used in gas-graphite reactors is made up of an uranium fuel tube, an external can and an internal can made of magnesium alloy. For the thermal exchange between the internal can and the fuel to be satisfactory, it is necessary for the can to stay in contact with the uranium under all temperature conditions. This report, based on a theoretical study, shows how the internal can fuel gap varies during the processes of canning, charging into the reactor and thermal cycling. The following parameters are considered: tube diameter, pressure of the heat carrying gas, gas entry temperature, plasticity of the can alloy. It is shown that for all operating conditions the internal can of a 77 x 95 element, planned for a gas-graphite reactor with a 40 kg/cm{sup 2} gas pressure, should remain in contact with the fuel. (authors) [French] La cartouche d'un element combustible annulaire, a refroidissement interne et externe pour reacteur graphite-gaz, est composee d'un tube combustible en uranium, d'une gaine externe et d'une gaine interne en alliage de magnesium. Pour que l'echange thermique entre la gaine interne et le combustible soit bon, il faut que la gaine reste appliquee sur l'uranium quel que soit le regime de temperature. Cette note a pour but de montrer comment, d'apres une etude theorique, le jeu combustible-gaine interne varie au cours des operations de gainage, de chargement dans le reacteur, et des cyclages thermiques. Les parametres suivants sont etudies: diametres de tube, pression du gaz caloporteur, temperature d'entree du gaz, plasticite de l'alliage de gaine. Il est montre que, quel que soit le regime de fonctionnement, la gaine interne d'un element 77 x 95, en projet pour un reacteur graphite-gaz sous pression de 40 kg/cm{sup 2}, doit rester appliquee sur le combustible.

L’étude de la fraction saponifiable a été consacrée, d’une part, à la détermination de la composition quantitative et qualitative en acides gras des différentes huiles dont les résultats ont fait l’objet d’une publication antérieure [1] et, d’autre part, à celle de leurs triacylglycérols. Une comparaison des compositions en acides gras des deux genres étudiés a permis de mettre en évidence les spécificités propres à chaque genre. Les genres Lagenaria et Luffa, présentant une composition en acides gras qualitativement similaire, contiennent ainsi les AG couramment rencontrés dans le règne végétal, à savoir les acides palmitique, stéarique, oléique et linoléique. Ce dernier est, par ailleurs, l’acide gras majoritaire avec des teneurs supérieures à 50%. La présence de cet acide gras essentiel confère ainsi à ces huiles de bonnes propriétés diététiques et nutritionnelles. Au sein du genre Lagenaria, les huiles des graines des variétés bouteille et la gale se caractérisent par leur teneur élevée en acide linoléique (71,5% pour la variété bouteille, et 81,5% pour la variété la gale. Les huiles de Lagenaria leucaritha sont du type palmitique-linoléique car ces deux acides gras représentent quantitativement plus de 85% des AG totaux. Contrairement à ces deux huiles, celles du genre Luffa se différencient, d’une part, par une teneur moindre en acide linoléique avec 55,3% pour l’espèce Luffa acutangula et 51,2% pour l’espèce Luffa cylindrica. D’autre part, elles sont du type palmitique-oléique-linoléique puisque ces trois

(author) [French] Les auteurs ont etudie la possibilite, le mecanisme et les consequences de la fusion et autres accidents nucleaires graves dans les reacteurs experimentaux a neutrons rapides de puissance zero, du type ZPR-III, a coeur divise. Cette etude a ete completee par une evaluation de l'importance de l'effet Doppler sur un grand nombre de reacteurs de ce type. Les auteurs demontrent qu'il est fort peu probable qu'une fusion se produise, du fait que la conjonction des circonstances qui pourraient la provoquer est difficilement realisable. L'expose du mecanisme de fusion est suivi de l'analyse des resultats de calculs couples neutronique-hydrodynamiqu e relatifs a deux reacteurs de puissance zero. On a choisi pour cette etude un coeur de 1200 l, qui correspond a un reacteur relativement grand a coeur normal. L'etude a egalement porte sur un coeur plus petit ayant un coefficient cavitaire plus important, qui pourrait presenter un plus grand danger. Chaque systeme a eu un comportement en fonction du temps tout a fait different. Si un accident grave survient dans un reacteur de puissance zero, les atomes de {sup 235}U, isoles dans les plaques d'uranium enrichi, s'echauffen t tres rapidement tandis que le reste du coeur demeure pratiquement froid; il y a ainsi formation d'un gaz du {sup 235}U qui donne lieu a la pression de rupture. Les auteurs expliquent l'adaptation qu'ils ont faite du code AX-I de neutronique-hydrodynamiqu e pour l'appliquer a un gaz de Van der Waals. Une autre modification importante de l'equation d'etat utilisee dans ce code consiste a employer une equation du type Mie-Grueneisen, derivee de la theorie de l'etat solide. Cette modification permet d'evaluer de facon plus satis- faisante le terme de pression pour les coeurs de composition variable.

    Full Text Available Literary genre of the stories in die Book of Daniel The literary genre of the stories in the book of Daniel has acquired a central position in modern research. Most researchers agree that the stories contain material that is older than the visions contained in Daniel 7-12. Corresponding to the narrative of Daniel and his three friends the following can be listed: the biblical stories of Joseph and Esther; the Assyrian story of Ahikar; the stories of Tobit and Judith; Daniel and Susannah; Daniel, Bel and the Snake; and the story in 1 Esdras 3:1-4:63. The issue regarding the genre of these narratives thus should be addressed. The article proposes that the Daniel stories be read as wisdom literature. Furthermore, the different opinions of the following researchers are discussed: W.L. Humphreys, J.J. Collins, R.R. Wilson, P.R. Davies, G.W.E. Nickelsburg, as well as S. Niditch and R. Doran. The conclusion arrived at is that no consensus on the classification of the genre of the stories exists and that the lack of a standardised system in the classification of genre hampers the discussion.

    Full Text Available When speaking of progress, photography is one of the things that is experiencing a quite vast development, and relatively wide in terms of technology or its visual feature. What it means by visual feature here is that in a long period of time, a lot has changed in its idea or concept. Also, it means the print media, or even its printing technique. Moreover he most basic of all is its character of the result in the photo itself. Whether the object taken, moment or time of the photo shoot, all these factors quite represent several genres in photography. For example, if the photography is making a human being to become its model, it might mean a modeling photo shoot, kids, or family photo shoot. Also it might mean a studio/indoor photo shoot or an outdoor photo shoot, when speaking of genre category. If the photo taken is a moment or an event, it might be a journalistic genre or a documentation one. Several themes or visual feature in a photo shoot will become one of the aspects for us the subject to be able to categorize the kind of genre they are. Hence, those genres definitely serve different functions. 

  3. Exploiting link structure for web page genre identification

    2015-01-01

    As the World Wide Web develops at an unprecedented pace, identifying web page genre has recently attracted increasing attention because of its importance in web search. A common approach for identifying genre is to use textual features that can be extracted directly from a web page, that is, On-Page features. The extracted features are subsequently inputted into a machine learning algorithm that will perform classification. However, these approaches may be ineffective when the web page contains limited textual information (e.g., the page is full of images). In this study, we address genre identification of web pages under the aforementioned situation. We propose a framework that uses On-Page features while simultaneously considering information in neighboring pages, that is, the pages that are connected to the original page by backward and forward links. We first introduce a graph-based model called GenreSim, which selects an appropriate set of neighboring pages. We then construct a multiple classifier combination module that utilizes information from the selected neighboring pages and On-Page features to improve performance in genre identification. Experiments are conducted on well-known corpora, and favorable results indicate that our proposed framework is effective, particularly in identifying web pages with limited textual information. © 2015 The Author(s)

    2012-08-01

    In this study, we attempt to identify motives pivotal in choices made regarding online and offline game genres and assess whether they are meaningful predictors of Internet addiction. A separate goal was to determine how an assessment of Internet-related cognitions compares to criteria-based research instruments on Internet addiction, and demonstrate its clinical usefulness. We are using data from a cross-sectional study of the entire adolescent student population aged 12-18 of the island of Kos. Results indicate that specific game genres and motives for choosing a game are important predictors of Internet addiction, even after accounting for sociodemographic and Internet-use-related variables. Gender differences are not statistically important when we account for genre choices and motives for choosing them. Boys' thought content tends to revolve more around their Internet use compared to girls. Several patterns of motives to play specific genres were identified with the help of a canonical correlation analysis, demonstrating the fact that the simple observation of overt behavior is not enough to deduce the meaning of these actions for the individual. Using multiple measures of online addiction, examining genre preferences and underlying motives for choosing a game can be helpful in reaching a better understanding of the individual game player.

L’hypothèse principale est que les femmes et les hommes utilisent le droit de manière différente lorsqu’ils sont confrontés à une discrimination raciale, parce qu’ils développent différentes représentations du droit et ont des expériences différenciées de la discrimination.  L’usage ou le non-usage du droit dépend également de l’identité personnelle et sociale que la personne entend se construire. Pour le démontrer, nous nous appuierons sur des méthodes quantitatives (analyse de la jurisprudence et de dossiers de plainte et qualitatives (entretiens avec des juristes et des plaignants. Les différences par genre seront analysées à trois niveaux : celui de l’expérience différenciée de la discrimination raciale, celui de l’utilisation des ressources, celui enfin, des motivations du recours au droit.

    In order to determine experimentally the amount of radiolysis in the swimming-pool reactor Triton, direct measurements have been made of the quantity of radiolysis gas and hydrogen peroxide in the water, at the entry and exit of the core. The concentration distribution of these gases in the reactor was also determined. An explanation is given as to why no gases evolution is seen in the swimming-pool reactors of the C.E.A. The overall amount of radiolysis is zero, and a simple interpretation of this result is possible. The real amount of radiolysis occurring in the reactor core can be calculated. This is in satisfactory agreement with certain measurement mad elsewhere. (authors) [French] Pour determiner experimentalement le taux de radiolyse dans la pile piscine Triton, des mesures directes de la quantite de gaz de radiolyse et d'eau oxygenee dans l'eau a l'entree et a la sortie du coeur ont ete faites. La repartition de la concentration de ces gaz dans la piscine a egalement ete determinee. On explique pourquoi aucun degagement gazeux n'est observe dans les piles piscines du CE.A. Le taux de radiolyse global est nul, et une interpretation simple de ce resultat est possible. Un taux de radiolyse reel dans le coeur du reacteur peut etre calcule. Celui-ci est en accord satisfaisant avec certaines determinations faites ailleurs. (auteurs)

  14. Between solidarity and argument: Interpersonal negotiation in two legal genres

    Directory of Open Access Journals (Sweden)

    Krisda Chaemsaithong

    2016-11-01

    Full Text Available This study presents a comparative examination of interpersonal negotiation in two monologic courtroom genres: the opening statement and closing argument. Drawing upon a corpus of three high-profile American trials, the quantitative and qualitative analysis identifies the traces and degree of the jury’s presence through lexico-grammatical resources, and reveals distinct interactional patterns, which are indicative of the interactive goals of the two speech genres. Such relational practice does not merely “oil the wheels” of courtroom communication, but also constitutes a key way in the meaning-making process of these genres. The findings attest to the centrality of relational work in accomplishing transactional goals in institutional discourses.

    2013-12-01

    Music genres are the simplest and effect descriptors for searching music libraries stores or catalogues. The paper compares the results of two automatic music genres classification systems implemented by using two different yet simple classifiers (K-Nearest Neighbor and Naïve Bayes). First a 10-12 second sample is selected and features are extracted from it, and then based on those features results of both classifiers are represented in the form of accuracy table and confusion matrix. An experiment carried out on test 60 taken from middle of a song represents the true essence of its genre as compared to the samples taken from beginning and ending of a song. The novel techniques have achieved an accuracy of 91% and 78% by using Naïve Bayes and KNN classifiers respectively.

  18. Music genre classification via likelihood fusion from multiple feature models

    Music genre provides an efficient way to index songs in a music database, and can be used as an effective means to retrieval music of a similar type, i.e. content-based music retrieval. A new two-stage scheme for music genre classification is proposed in this work. At the first stage, we examine a couple of different features, construct their corresponding parametric models (e.g. GMM and HMM) and compute their likelihood functions to yield soft classification results. In particular, the timbre, rhythm and temporal variation features are considered. Then, at the second stage, these soft classification results are integrated to result in a hard decision for final music genre classification. Experimental results are given to demonstrate the performance of the proposed scheme.

  19. BIOGRAPHY GENRE IN RUSSIAN LITERATURE: EUROPEAN AND BRITISH INFLUENCES

    Directory of Open Access Journals (Sweden)

    Eugenia V. Ivanova

    2016-12-01

    Full Text Available The article examines the development of the genre of biography and life writing that influenced Russian biographical tradition. This tradition stems from Plutarch’s Comparative Biographies that influenced English life writing represented by such names as James Boswell, Lytton Strachey, and others. Philosophical premises of the English biography genre are to be found in the treatise Heroes, HeroWorship, and The Heroic in History (1841 by Thomas Carlyle. French tradition represented by Gaston Tissandier’s book Science Martyrs pursued the opposite aim: to honor ordinary scientists and inventors, responsible for the technical advance of the modern civilization. Wilhelm Dilthey and Georg Simmel practiced a different approach to life writing in that they conceived biography as the history of the person’s spiritual development. This conception had direct influence on the theorists of biography genre in Russia, G. O. Vinokur, and A. G. Gabrichevsky.

    Full Text Available This paper builds on the work presented at the ECDL 2006 in automated genre classification as a step toward automating metadata extraction from digital documents for ingest into digital repositories such as those run by archives, libraries and eprint services (Kim & Ross, 2006b. We have previously proposed dividing features of a document into five types (features for visual layout, language model features, stylometric features, features for semantic structure, and contextual features as an object linked to previously classified objects and other external sources and have examined visual and language model features. The current paper compares results from testing classifiers based on image and stylometric features in a binary classification to show that certain genres have strong image features which enable effective separation of documents belonging to the genre from a large pool of other documents.

    The chemical effect of ionizing radiations on a certain number of gaseous systems is described. Under the influence of radiations from a reactor, NH{sub 3}, is decomposed to nitrogen and hydrogen in stoichiometric proportions. Formation of N{sub 2}H{sub 3}, particularly could not be detected. Under a slow neutron flux the reaction {sup 14}N (n, p) {sup 14}C constitutes the main source of decomposition energy. Direct recombination of H, and N, has been brought about under the influence of radiation. The radiolysis of NH{sub 3}, occurs by a complex mechanism; and the kinetics follow a law of the order of about 2.5 which increases with the decomposition rate. The decomposition of hydrogen sulphide is appreciably faster than that of NH{sub 3}. Hydrogen is the only gaseous product of the reaction. The sulphur, which is deposited on the walls of the ampoules, is clearly visible to the naked eye. Up to the present decompositions up to 84 per cent have been obtained. The influence of the reaction {sup 32}S (n, p) {sup 32}P is considered. Radiochemical decomposition of nitrous oxide N{sub 2}O takes place with high yields. The reaction is complicated from the beginning by the formation of higher oxides of nitrogen which we identify and measure. Radiochemical decomposition of methane gives quantities of higher hydrocarbons. Certain of these gaseous systems could find applications in the measurement of high doses of radiation. This problem is discussed in the conclusion. (author)Fren. [French] L'effet chimique des rayonnements ionisants sur un certain nombre de systemes gazeux est decrit.

  2. Sorrow Songs and Mbira Music: Du Bois, Mapfumo, and the Power of Music

    Directory of Open Access Journals (Sweden)

    Shelia Bassoppo-Moyo

    2012-10-01

    Full Text Available This article examines how music functions as social commentary on a group’s lived experience and as a tool to inform identity. Music is a data source that articulates historical and cultural contexts and can thus be utilized as social commentary to socially construct the identity of people of African ancestry and descent. The "sorrow songs" are the music genre created by slaves in the American South and were considered by W. E. B. Du Bois as the most important historical narrative for African Americans. In comparison, the more contemporary "mbira music" or Chimeranga (rebellion songs of Thomas Mapfumo, led the liberation struggle against colonialism in Zimbabwe. His music played a journalistic role in communicating with the masses. Several theoretical perspectives were employed in this study which included Du Bois’ inductive, empirical framework for the study of "the Negro problems"; Georg Simmel’s perspective on the role of music in society; Berger and Luckmann’s social construction of reality; and O'Shaughnessy and Stadler's social construction of the media. This paper uses content analysis to analyze the musical lyrics of both genres. These musical forms shed light on Du Bois' understanding of the veil and double consciousness within the African American experience and Zimbabwe's struggle for liberation respectively. Points of intersection between the two genres provide insight into how music creates knowledge and constructs social reality.

  1. GENRE MIGRATION IN “ARTIST” BY NIKOLA PETROV

    2016-10-01

    Full Text Available The study aims at identifying, examining and analyzing the Dynamics in the genre of the picture “Artist” by Nikola Petrov and the reasons for its migration aspirations. Evidence is argumentatively applied in defence of the thesis that at different stages of the artistic life of the work it comes under three well-grounded distinct painting genres; self-portrait, portrait (single and double and one figure composition (with the “presence” of a latent image. The hypothesis of genre migration is built on the basis of circumstances and facts that “accompany” the work from its creation till becoming part of a donation by the heirs of the author to a gallery in his hometown. An idea is argued that the simultaneous presence of several genres in the painting is unique for Bulgarian art from the early 20th century, which dimensions could only be rationalized when compared with current ideas and practices in art and nowadays views of portraying in particular. An inference is made in the text by proving that the hypothesis also applies to subsequent paradigm shifts with the time regarding portraying.

  3. Music Genre Classification Using MIDI and Audio Features

    Cataltepe, Zehra; Yaslan, Yusuf; Sonmez, Abdullah

    2007-12-01

    We report our findings on using MIDI files and audio features from MIDI, separately and combined together, for MIDI music genre classification. We use McKay and Fujinaga's 3-root and 9-leaf genre data set. In order to compute distances between MIDI pieces, we use normalized compression distance (NCD). NCD uses the compressed length of a string as an approximation to its Kolmogorov complexity and has previously been used for music genre and composer clustering. We convert the MIDI pieces to audio and then use the audio features to train different classifiers. MIDI and audio from MIDI classifiers alone achieve much smaller accuracies than those reported by McKay and Fujinaga who used not NCD but a number of domain-based MIDI features for their classification. Combining MIDI and audio from MIDI classifiers improves accuracy and gets closer to, but still worse, accuracies than McKay and Fujinaga's. The best root genre accuracies achieved using MIDI, audio, and combination of them are 0.75, 0.86, and 0.93, respectively, compared to 0.98 of McKay and Fujinaga. Successful classifier combination requires diversity of the base classifiers. We achieve diversity through using certain number of seconds of the MIDI file, different sample rates and sizes for the audio file, and different classification algorithms.

    1999-12-01

    This study was designed to examine whether people's expectations differ regarding how music lyrics affect individual behavior as a function of music genre. Because legislative attention and media publicity have been biased against certain types of popular music (i.e., heavy metal and rap), the authors expected that those genres of music would be viewed more negatively than other genres of popular music, for which there has been little or no negative publicity (i.e., pop and country). Participants (N = 160 college students) rated their perceptions of how the lyrical content of a song would affect listeners' behavior. The authors presented prosocial or antisocial lyrical passages to students (N = 160) under the guise of four musical genres (heavy metal, rap, pop, and country). Participants rated the potential impact of the lyrics on listeners' behavior. Findings indicated that lyrics labeled as heavy metal or rap were perceived as less likely to inspire prosocial behavior but not more likely to inspire antisocial behavior than the same lyrics labeled as country or pop.

  14. Genre Transformation of the Fairy Tale in Contemporary Russian Literature

    Directory of Open Access Journals (Sweden)

    Ekaterina Zueva

    2017-09-01

    Full Text Available This research is devoted to some peculiarities of structure and semantics of contemporary Russian fairy tale. The analyzed genre model is quite actual in the literature of modern turn of the centuries. It is actualized in the creativity of L. Petrushevskaya, A. Kabakov, B. Akunin, M. Fray, D. Bykov, etc. This is connected with the universality of themes and problems and the dynamics of structure of genre analyzed. Modern literature process suggests the use of various genre forms (including fairy-tale one in the context of realization of game strategies of world construction with the deconstruction principle domination. The usage of the most productive for such kind of research methods (structural-semantical and comparative ones gives grounds for understanding the specifics of realization of deconstruction principle through the variety of forms and meanings. For example, the scheme of “genre memory” is widely used in contemporary fairy tale. If that scheme deals with the sphere of semantics, then structural components are actively deconstructed (e.g. fairy tales by L. Petrushevskaya. If the meaningful fairy tale composition models are actualized, then the semantic component is widely transformed (e.g. Moscow Fairy Tales by A. Kabakov. The most important peculiarity of contemporary fairy tale is the integration of fairy tale, legendary, mythological and literary plots to the one game system. The result of this is on the one hand travestying of the iconic plots, on the other hand achieving the new meanings due to including context mechanisms.

    This paper deals with the use of pre-stressed concrete for the G2 and G3 reactors at Marcoule and for the EDF3 reactor now under construction at Chinon. The first two reactors have been operating at power since 1959 and 1960 respectively. Messrs. Conte and Dambrine discuss the problems that arose during construction of the vessels for G2 and G3 and also deal with the experience gained in operation - experience which suggests that they are extremely safe- Work on the EDF3 vessel, begun at Chinon in the second half of 1961, is still under way and should be finished towards the end of 1963. Mr. Gaussot discusses the reasons for choosing this type of vessel, the results of calculations and mock-up tests, and the problems presented by the construction itself. A number of studies have been devoted to the future prospects of prestressed concrete structures for reactors. It would seem that working pressures could be increased, if desired, and, in any case, that dimensions could be considerably enlarged, thus offering the chance of integral-type solutions.

    The subjects is an experimental out-of pile loop study of the hydrodynamic oscillations occurring in boiling-water reactors. The study was carried out at atmospheric pressure and at pressure of about 8 atmospheres, in channels heated electrically by a constant and uniform specified current. In the test at 8 atmospheres the channel was a round tube of approximately 6 mm interior diameter. At 1 atmosphere a ring-section channel was used, 10 * 20 mm in diameter, with an inner heating tube and an outer tube of pyrex. It was possible to operate with natural convection and also with forced convection with test-channel by-pass. The study consists of 3 parts: 1. Preliminary determination of the laws governing pressure-drop during boiling. 2. Determination of the fronts at which oscillation appears, within a wide range of the parameters involved. 3. A descriptive study of the oscillations and measurement of the periods. The report gives the oscillation fronts with natural and forced convection for various values of the singular pressure drop at the channel inlet and for various riser lengths. The results are presented in non-dimensional form, which is available, in first approximation, for all geometric scales and for all fluids. Besides the following points were observed: - the wall (nature and thickness) can be an important factor ; - oscillation can occur in a horizontal channel.

Lastly, a few words are said about the liquid helium loop, a prototype of which has worked, and which is being rebuilt with an increased power. (authors) [French] L'etude des defauts crees par l'irradiation dans les solides est d'un interet theorique et pratique, considerable. L'irradiation a basse temperature permet d'obtenir les defauts dans leur etat le plus simple, leur etat 'primaire' sans que l'agitation thermique permette leur annihilation ou leur rearrangement. L'irradiation en pile a basse temperature pose un certain nombre de problemes techniques provenant de la puissance de refrigeration necessaire, qui est quelquefois considerable, des reactions chimiques possibles sous rayonnement et du manque d'espace dans un reacteur. Enfin, la necessite de faire toute l'irradiation et les mesures ulterieures sans rechauffer les; echantillons impose que le dispositif fonctionne en continu sans defaillance et qu'il soit equipe de facon a permettre la recuperation des echantillons froids, ou bien leur mesure et leur rechauffage controle 'in situ'.

Nous avons cru bon de rappeler quelques generalites concernant la dynamique des reacteurs, les differents procedes de detection des neutrons, le fonctionnement des chambres d'ionisation et les methodes de mesure utilisees. Notre contribution aux techniques de controle des reacteurs consiste d'une part en une tentative de synthese des facteurs intervenant dans le fonctionnement des chambres d'ionisation, l'etude de ces facteurs, et d'autre part l'elaboration de chambres d'ionisation a fission et a bore permettant de suivre la marche d'un reacteur du demarrage jusqu'a la puissance maximale. Dans le domaine des chambres a fission, nous avons en particulier ameliore les techniques de depot d'oxyde d'uranium sur l'aluminium et realise la mise au point de depots par electrolyse sur d'autres metaux: acier inoxydable, cuivre, molybdene, nickel, tantale, titane, kovar, tungstene et beryllium. Nous avons elabore plusieurs types de chambres a fission servant au demarrage des reacteurs: un type de performances moyennes actuellement utilise dans les piles francaises un type a haute sensibilite un type a haute temperature qui a fonctionne jusqu'a 600 deg. C. En ce qui concerne les chambres a bore, nous avons etudie les perturbations apportees dans les mesures par l'exposition des chambres a d'importants flux de neutrons et a un rayonnement {gamma} intense. Cette exposition produit une modification des proprietes des materiaux constitutifs et la production dans les chambres d'un bruit de fond qui peut gener considerablement les mesures neutroniques. Nous avons montre que la technique de compensation permettait de limiter l'importance de ce bruit de fond et d'augmenter ainsi la plage de fonctionnement des chambres d'ionisation classiques destinees aux mesures de puissance. Enfin, nous avons realise deux

    I - Special tests for improving the sensitivity of burst cartridge detection equipment in power reactors II - Scintillator purge-flow tests using aged gas in the B.C.D. /E.D.F. 2 Summary. - The first part of this report describes the tests carried out on fission product detectors by a process in which gas is continuously injected in front of the scintillator. Using this system, the background is reduced and perturbations caused by pneumatic switches on the prospecting circuits are eliminated. The quality of the signals thus obtained permits better processing of the data and thus leads to a possible improvement in the sensitivity of burst cartridge detection. The second part gives results of tests carried out with both fresh and aged gases, the economic advantage of the latter being that it permits recycling through the reactor. Reduction of the background is less pronounced but the advantage of the stable signals is conserved.

    Bursting of a pressure tube in the tank of a heavy water moderated-gas cooled reactor is an accident which has been studied experimentally about EL-4. A first test (scale 1) having shown that the burst of a tube does not cause the rupture of adjacent tubes, tests on the tank resistance have been undertaken with a very reduced scale model (1 to 10). It has been found that the tank can endure many bursts of tube without any important deformation. Transient pressure in the tank is an oscillatory weakened wave, the maximum of which (pressure peak) has been the object of a particular experimental study. It appears that the most important parameters which affect the pressure peak are; the pressure of the gas included in the bursting pressure tube, the volume of this gas, the mass of air included in the tank and the nature of the gas. A general method to calculate the pressure peak value in reactor tanks has been elaborated by direct application of experimental data. (authors) [French] L'eclatement d'un tube de force dans la cuve d'un reacteur de puissance modere a l'eau lourde et refroidi par un gaz sous pression est un accident qui a ete etudie experimentalement a propos d'EL-4. Un premier essai a l'echelle 1 ayant montre que l'eclatement d'un tube ne provoque pas celui des tubes voisins, des essais relatifs a la tenue de la cuve ont ete effectues sur maquettes a echelle tres reduite (l/lO). Il a ete trouve que la cuve peut supporter plusieurs eclatements de tubes sans deformations notables. La pression transitoire dans la cuve a une allure oscillatoire amortie dont le maximum (pression de pic) a fait l'objet d'une etude experimentale detaillee. Il apparait que les parametres essentiels influant sur cette pression sont: la pression du gaz contenu dans le tube de force, le volume du gaz qui participe a l'eclatement, la flexibilite de la cuve, la masse d'air empoisonnee dans la cuve, la nature du gaz explosant.

The investigation of the control, carried out on analog computer, served to determine the different possible means of starting and changing the conditions of the reactor as well as its automatic control. The calculations were examined in the totality by the construction of a training simulator composed of a board similar to the control board of the reactor, all of whose commands (reactivity and flows) work on an analogue computer which resolves in the real time the dynamic equations of the reactor and which reproduces simultaneously all the parameters representing the state of the installation (power, period, temperatures, etc. ) in the case of various incidents as well as under normal conditions of functioning.

    Online music databases have increased significantly as a consequence of the rapid growth of the Internet and digital audio, requiring the development of faster and more efficient tools for music content analysis. Musical genres are widely used to organize music collections. In this paper, the problem of automatic single and multi-label music genre classification is addressed by exploring rhythm-based features obtained from a respective complex network representation. A Markov model is built in order to analyse the temporal sequence of rhythmic notation events. Feature analysis is performed by using two multivariate statistical approaches: principal components analysis (unsupervised) and linear discriminant analysis (supervised). Similarly, two classifiers are applied in order to identify the category of rhythms: parametric Bayesian classifier under the Gaussian hypothesis (supervised) and agglomerative hierarchical clustering (unsupervised). Qualitative results obtained by using the kappa coefficient and the obtained clusters corroborated the effectiveness of the proposed method.

    Full Text Available The films of French director Robert Bresson are considered sober and transcendental. However, in A gentle woman (1969 and in Four nights of a dreamer (1972, he included extracts of quite different genres, like a libertine comedy (the extract of film Benjamim by Michel Deville, 1968, a Shakespearean tragedy (a performance of Shakespeare´s Hamlet and a gangster film (When love possesses us, produced by Bresson himself. In a way, those excerpts represent exactly the opposite of Bresson´s cinema. On the other hand, they still have some familiarity with it. We analyze the approach of those genres in the sequences in Bresson´s films, as well of the styles present in them by the use of music and images of paintings.

    Though the notion of a scientific textbook has been around for almost three centuries, the category has hardly been stable. The plasticity of the textbook genre may be illustrated by recent variations as well as long-term trends. In this brief essay I examine two idiosyncratic but highly successful physics books, each published in the mid 1970s, whose production, marketing, and adoption reveal some of the slippage between such categories as textbook, scholarly monograph, and popular best seller.

  17. An Anthology as a Representative Genre in Contemporary Ukrainian Literature

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available In this article is analyzed a history and functions of an anthology in a modern Ukrainian literature from the last quarter of the 19th c. to the beginning of the 21st. An anthology is treated as a literary and anthropological project which is characterized by recasting of original materials and specific politics of its re-arangement. It proposes a new cultural value hierarchy, defines a literary field and the rules of its organization. As a form of literary self-representation an anthology participates in a process of forming a literary tradition and canon, its diversification up to the emergence of anti-canon; it intensifies a work of cultural memory, represents new literary genres and styles and also indicates an appearance of diaspora as a model of cultural citizenship. Numerous anthological projects also stress spacial, performative, subjective, gender, erotical, somatic, and oneirological aspects of creative writing; they rethink a very nature of literature as a creative experiment and as a social action in a context of mass culture and new media development. This allows us to consider the literary anthology as a way of a literary self-reflection and as a separate meta-genre in modern Ukrainian literature. The main genre-defining anthological qualities are such as selectivity, double methonimity, integrity and an ability to create new cultural values. The history of anthology as a specific meta-genre helps us to understand the general pecularities of modenr and postmodern literature, its structure and principles of development, its key problems and challanges and also its the most important achievements.

Les résultats de terrain montrent l'obtention de rendements et profits plus élevés lorsqu'on utilise le compost. Les résultats de la fonction de production Cobb-Douglas prouvent que l'utilisation du compost est statistiquement significative pour expliquer la variation de rendement de la laitue et que le compost est l'intrant le plus productif. D'autres résultats montrent que le compost fournit la matière organique utile au sol et que les besoins d'irrigation en eau de la culture sont réduits grâce à l'utilisation du compost. Par conséquent, malgré le fait que l'application du compost demande une main-d'oeuvre beaucoup plus élevée, son utilisation est généralement bénéfique pour les agriculteurs vivant aux alentours de Yaoundé. Les programmes de vulgarisation de cet intrant pour encourager son adoption devraient donc figurer parmi les points prioritaires dans la politique agricole du gouvernement camerounais.

    2016-06-01

    Full Text Available The article analyzes the works of Tula folklore recorded in the western part of the Tula region, in terms of genre, stylistic and linguistic features. The relevance of the study is related to the fact that Tula folk songs has not been studied, linguistic features of the works are not subjected to serious analysis. The article describes the features of the genre of songs recorded in Belevsky district of Tula region, including the ancient fortunetelling chants, wedding ceremony songs, romantic ballads etc., it is cited numerous examples in the lyrics that reflect the dialectal features of the phonetic, grammatical, lexical levels. According to the authors, a modern folk song genre retains its diversity and is a kind of storeroom containing priceless linguistic wealth. The analysis allows to draw conclusions about the presence and well-preserved in the recorded music of South Russian dialect phonetic and grammatical features. So far, there is no established typology of Tula dialects, therefore, according to the authors, the fixation of folklore in the territories bordering on Tula dialects, is very important and interesting for further descriptive and comparative work on identifying the eastern and south-south-west differences in Tula dialects.

  1. Elegy as a film genre. Adaptation — inspiration — suggestion

    Directory of Open Access Journals (Sweden)

    Rafał Koschany

    2011-01-01

    Full Text Available The question that this is article is concerned to answer is how the position of the film elegy can be best formally established — with its artistic representations, as well as its functioning in the genology of the genre. An attempt to provide definitive answers that emerge from interdisciplinary, film and literary discourse brings a number of substantial threads. Firstly, there is, indeed, no theoretical description of the elegy as a film genre, though the very name does appear in many titles. Secondly, it seems that a juxtaposition of available examples of film ad-aptations of elegies does not lead to any consistent conclusion, since, apart from the suggestion proposed by the author, they are different in terms of formal and thematic elements involved. Thirdly, any attempt at a genological profiling has to, somehow, refer to a more or less fixed literary genre and the relevant theory behind it. In a most general way, one can state, albeit with a number of reservations, that the elegiac film is characterized by a distinguishable style, often simply called the elegiac style, and the theme, very broadly associated with time and the theme of passing.

  2. Indigenizing the Zarzuela: Kapampangan Ethnocentric Adoption of the Foreign Genre

    Directory of Open Access Journals (Sweden)

    Julieta C. Mallari

    2011-03-01

    Full Text Available When the Spanish colonizers reached Pampanga, a province in the northern part of the Philippines, the meeting between the East and the West meant an impact of the grafted civilization over the conquered people. Religious and cultural hybridization (Bhaba 1994 inevitably took place in Pampanga. Kapampangan verbal art modestly welcomed an alien counterpart and a cultural synthesis in a “liminal space” took place. What the Spaniards introduced—religious literature, metrical romances and the zarzuela—to advance their imperialistic cause pressed on the folk and blended naturally with the Kapampangan sensibility. Kapampangan literature took on a hybrid form that came to be an incitement for the movement of the province’s literary history. Mariano Proceso Pabalan Byron, a Kapampangan poet, was the first to domesticate the form and content of the zarzuela, a Spanish literary genre. He, together with other writers such as Crisostomo Soto, established a zarzuela tradition and produced masterpieces. The enthusiasm for the zarzuela lasted for decades even after World War II; poets like Jose Gallardo easily adopted the favorite literary genre of his predecessors. The genre was most welcome because its elements constituted their familiar world. The zarzuelas that were produced reveal the constant appropriation of the native values and beliefs in the foreign literary form.

  3. Legal genres in English and Spanish: some attempts of analysis

    2009-10-01

    Full Text Available Understanding the differences and subtleties between the legal communication of the English-speaking world, and the Continental law countries –and, more specifically, Spain- has become a necessary practice in the global context. For the most part, it involves unravelling the differences and concomitances between the array of legal genres produced by the professionals of the specialist communities within these two traditions (i.e., Common Law and Continental Law. This paper attempts an analysis in layers –generic or pragmatic, textual or cognitive, and formal or superficial– of two types of genre within the domain of public and private law, namely delegated legislation and tenancy agreements or leases, the study of which has been seldom attempted, despite the customary presence of these instruments in the legal routine. The result of such analysis will, hopefully, cast some light on the way these communities interact within themselves and with the rest of the world, providing new clues to tackle the application of those genres and making it possible to draw new conclusions about the way in which linguistic interaction takes place in the context of these specialist communities in English and Spanish.

In this way, this article makes a practical-theoretical exercise of an inductive nature which rescues how categories of the communicative situation and the analysis of elements such as supports allow a greater deepening of different dimensions in the media discursive practices (social relation, themes, etc. as well as observing to what extent we are talking about discursive genders and sub genders in daily life.

    2015-11-01

    Full Text Available The business plan has been widely included in the curricula of economics degrees and is key to business practice worldwide, but has not been studied from a socio-discursive perspective yet due to restrictions in its social, spatial, and temporal circulation. Based on interviews and a qualitative analysis of a corpus of 38 texts written in Spanish, I aim to provide a preliminary description of the genre. Results indicate that a chain of four phases is associated to a continuum of social settings organized through entrepreneurial/corporate and expert/training variables; its rhetorical structure includes “describing present/potential situation of the company and market” and “describing future processes of strategic actions regarding the marketing, production, and financial plans”. This analysis offers methodological innovations to account for occluded genres, encourages the contrastive study of the business plan in different cultural and linguistic environments, and assists business teachers with a situated picture of the genre

    Full Text Available The main thrust of this study was to determine whether a genre-based instruction improve the writing proficiency of Iranian EFL learners. To this end, 30 homogenous Iranian BA learners studying English at Islamic Azad University, Bandar Abbas Branch were selected as the participants of the study through a version of TOEFL test as the proficiency test. The selected participants were 15 females and 15 males who were randomly divided into two groups of experimental and control. The both experimental and control groups were asked to write on a topic determined by the researcher which were considered as the pre-test. The writing of the students were scored using holistic scoring procedure. The subjects received sixteen hours instruction—the experimental group using a genre-based pedagogy and the control group through the traditional methodology which was followed by a post-test—the subjects were, this time, asked to write on the same topic which they were asked to write before instruction. Their post-writings were also scored through the holistic scoring procedures. In analyzing the data, t-test statistic was utilized for comparing the performances of the two groups. It was found that there is statistically significant difference between the writing ability of the participants who go under a genre-based instruction and who don’t. The study, however, didn’t find any significant role for gender. Keywords: genre analysis, writing skill, holistic scoring procedure, pre-test, post-test, t-test

    The results of experiments in the light water cooled D{sub 2}O reflected critical assembly ALIZE III have been compared to calculations. A diffusion model was used with 3 fast and epithermal groups and two overlapping thermal groups, which leads to good agreement of calculated and measured power maps, even in the case of strong variations of the neutron spectrum in the core. The difference of calculated and measured k{sub eff} was smaller than 0.5 per cent {delta}k/k. Calculations of void and structure material coefficients of the reactivity of 'black' rods in the reflector, of spectrum variations (Cd-ratio, Pu-U-ratio) and to the delayed photoneutron fraction in the D{sub 2}O reflector were made. Measurements of the influence of beam tubes on reactivity and flux distribution in the reflector were interpreted with regard to an optimum beam tube arrangement for the Franco- German High Flux Reactor.

On a utilise un modele de la theorie de diffusion a trois groupes rapides et epithermiques et deux groupes thermiques qui se recouvrent. Ce modele a permis de calculer la distribution de puissance dans le coeur en bon accord avec les mesures, meme dans le cas d'une forte variation du spectre des neutrons dans le coeur. L'erreur entre k{sub eff} calcule et mesure etait inferieure a 0,5 pour cent {delta}k/k. Le coefficient de vide et des materiaux de structure, la reactivite des barres 'noires', les variations du spectre (rapport Cd, rapport Pu/U) et la fraction des photo-neutrons retardes sont egalement calcules.

Thermodynamic problems: various problems relative to temperature evolution in a reactor, in a pipe, in an exchanger, in a turbine, are studied, and simulation techniques used by earlier authors are critically reviewed. 3. Pipe simulators: it is shown that this problem can be solved by the use of specialized simulators which will be described and analysed. 4. Rotating machine simulators: the particular aspect of rotating machine calculations introducing frequent use of diagrams is emphasized. A simulator requiring both digital and analogue methods is described. 5. The study of a nuclear power station: as an example it is proposed to discuss problems a rising in connection with the preceding elements (a, b, c, d) when simulating the behaviour of large nuclear plants. The part played by ordinary computing elements for the simulation of the different servomechanism transfer functions is considered and process of regulation is outlined. 6.

    Music genre classification is one example of content-based analysis of music signals. Traditionally, human-engineered features were used to automatize this task and 61% accuracy has been achieved in the 10-genre classification. However, it's still below the 70% accuracy that humans could achieve in the same task. Here, we propose a new method that combines knowledge of human perception study in music genre classification and the neurophysiology of the auditory system. The method works by trai...

  18. Genre scripts and appreciation of negative emotion in the reception of film.

    Tan, Ed S; Visch, Valentijn T

    2017-01-01

    The Distancing-Embracing model reserves a role for genre scripts in the hedonic valuation of negative emotion in art. Genre scripts, as defined in the target article, leave higher-level recipient intuitions out of scope. We argue that, in film genre scripts, lower-level stylistic features lend access to more complex conceptual knowledge, including pragmatic principles. The argument implies a consideration of the communicative dimension of aesthetic works, which could strengthen both factors of the Distancing-Embracing model.

    Full Text Available L’exemple allemand analysé dans cet article montre comment les catégories du « masculin » et du « féminin » sont construites, transformées et utilisées en lien étroit avec l’identité nationale. Trois périodes – la révolution de 1848-1849, les années 1860 et la guerre de 1870 – sont successivement examinées à travers des textes produits par des Allemandes qui tentent de participer à la formation de l’opinion publique durant ces années-là. Ces sources (principalement de nature journalistique témoignent de leurs tentatives pour intervenir dans les débats du moment, pour exprimer des opinions politiques, pour revendiquer de nouveaux droits pour les femmes et définir pour elles un statut de citoyennes dans l’Etat allemand à venir. Pour se faire entendre, ces auteures doivent se montrer dignes de la nation allemande, et, par conséquent, s’exprimer non seulement « en tant que femmes » mais aussi en tant que « femmes allemandes » ; ceci implique de se distinguer clairement du stéréotype de la « femme française ». La revendication de cette double identité – genrée et nationale – s’avère à la fois indispensable et restrictive, comme on le voit avec les thèmes de l’émancipation et des droits politiques. Beaucoup de ces femmes publiquement engagées essaient donc d’élargir leur champ d’action en jouant sur la notion de « féminité » qu’elles sont obligées de prendre en compte ; il s’agit notamment de donner à cette notion un contenu nouveau et « moderne », en lien avec les problèmes de leur temps.Der Text zeigt anhand der Analyse des deutschen Beispiels auf, wie im Zusammenspiel mit der nationalen Identität Geschlechterkategorien im 19.

    regarding the specification of this parameter. These considerations are discussed in terms of control reactivity in existing fast reactors as opposed to the amount that is really required for fast power-breeder reactor operation. Typical power- and temperature-dependent feedback parameters are cited for determination of their influence upon the control reactivity requirements. The methods used to predict the reactivity worth of control mechanisms have evolved from crude estimates to quite reliable calculations which can be confirmed by experimental data from critical assemblies. Experimental results and currently reliable analytical techniques are described. Critical experiments for the current generation of fast reactors included many investigations pertaining to the reactivity worth of their control mechanisms as well as peripheral experiments for larger-core-volume advanced systems. Exploratory analytical studies, which indicate that detailed experimental mockup investigations may not be required in the future, are cited. (author) [French] L'auteur examine dans ce memoire les aspects pratiques du probleme qui consiste a fournir une reactivite suffisante pour le controle des reacteurs a neutrons rapides; ce probleme differe dans une grande mesure de celui du controle des reacteurs a neutrons thenniques. Ces differences sont dues en premier lieu au fait que les sections efficaces d'absorption des neutrons rapides sont assez faibles. Il n'existe pas de poisons forts dans un reacteur a neutrons rapides. En consequence, les poisons forts que sont certains produits de fission dans un reacteur thermique (par exemple Xe et Sm) exigent un exces de reactivite beaucoup moins important que n'en exige la perte de reactivite due a la destruction de produit fissile par fission et capture. Comme les sections efficaces pour les neutrons rapides sont relativement petites comparees aux valeurs correspondantes pour les neutrons thermiques, la densite atomique du materiau joue un role

    This work chiefly concerns the measurement of fast neutron fluxes by means of threshold detectors. It is shown first that the cross sections to use for measurements by threshold detectors depend largely on the neutron spectrum, that is the position in which the measurement is performed. The spectrum is determined by calculation for several positions in the piles EL2 and EL3; from this can be deduced the cross-sections to be used for the measurements carried out in these positions. In the last part of the report, possible methods for the experimental determination of the spectrum are indicated.

    Full Text Available Genre analysis dealing with the study of situated language in a particular context is regarded as a crucial component in every communication in general and academic writing texts in particular. Furthermore, recently it has been set as a requirement for the graduated students to pursue a shared rhetorical pattern for generating an academic text. Several researchers have recommended detailed explanations for rhetorical structures of various parts of academic texts, and an extensive literature is dedicated to investigate different academic genres such as research articles, theses, and dissertations in English. But, there are not enough studies that work on the thesis as a whole product and analyze all sections together and not separately. Therefore, 40 M.A. theses produced by Iranian TEFL students at Islamic Azad University (IAU, Isfahan (Khorasgan Branch were collected and analyzed for the rhetorical structures of the Introduction, Method, Results, and Discussion (IMRD sections in order to accomplish the objectives of the study. Through calculating the frequencies and percentages of data, it was revealed that a number of moves in different sections was absent in the theses.

    2002-04-01

    Full Text Available Genre analysis can be viewed from two different perspectives: it may be seen as a reflection of the complex realities of the world of institutionalised communication, or it may be seen as a pedagogically effective and convenient tool for the design of language teaching programmes, often situated within simulated contexts of classroom activities. This paper makes an attempt to understand and resolve the tension between these two seemingly contentious perspectives to answer the question: "Is generic description a reflection of reality, or a convenient fiction invented by applied linguists?". The paper also discusses issues related to the nature and use of linguistic description in a genre-based educational enterprise, claiming that instead of using generic descriptions as models for linguistic reproduction of conventional forms to respond to recurring social contexts, as is often the case in many communication based curriculum contexts, they can be used as analytical resource to understand and manipulate complex inter-generic and multicultural realisations of professional discourse, which will enable learners to use generic knowledge to respond to novel social contexts and also to create new forms of discourse to achieve pragmatic success as well as other powerful human agendas.

    Full Text Available Music Information Retrieval (MIR has become a popular research area in recent years. In this context, researchers have developed music information systems to find solutions for such major problems as automatic playlist creation, hit song detection, and music genre or mood classification. Meta-data information, lyrics, or melodic content of music are used as feature resource in previous works. However, lyrics do not often used in MIR systems and the number of works in this field is not enough especially for Turkish. In this paper, firstly, we have extended our previously created Turkish MIR (TMIR dataset, which comprises of Turkish lyrics, by including the audio file of each song. Secondly, we have investigated the effect of using audio and textual features together or separately on automatic Music Genre Classification (MGC. We have extracted textual features from lyrics using different feature extraction models such as word2vec and traditional Bag of Words. We have conducted our experiments on Support Vector Machine (SVM algorithm and analysed the impact of feature selection and different feature groups on MGC. We have considered lyrics based MGC as a text classification task and also investigated the effect of term weighting method. Experimental results show that textual features can also be effective as well as audio features for Turkish MGC, especially when a supervised term weighting method is employed. We have achieved the highest success rate as 99,12\\% by using both audio and textual features together.

  18. Transforming Musical Signals through a Genre Classifying Convolutional Neural Network

    Geng, S.; Ren, G.; Ogihara, M.

    2017-05-01

    Convolutional neural networks (CNNs) have been successfully applied on both discriminative and generative modeling for music-related tasks. For a particular task, the trained CNN contains information representing the decision making or the abstracting process. One can hope to manipulate existing music based on this 'informed' network and create music with new features corresponding to the knowledge obtained by the network. In this paper, we propose a method to utilize the stored information from a CNN trained on musical genre classification task. The network was composed of three convolutional layers, and was trained to classify five-second song clips into five different genres. After training, randomly selected clips were modified by maximizing the sum of outputs from the network layers. In addition to the potential of such CNNs to produce interesting audio transformation, more information about the network and the original music could be obtained from the analysis of the generated features since these features indicate how the network 'understands' the music.

    2012-10-01

    Full Text Available A great deal has been published about oral and written genres in business (e.g., letters, research articles, oral presentations, etc., and less attention has been paid to business research article abstracts as a written genre, as many experts would argue. This research intends to raise rhetorical awareness about the role of abstracts in today’s academic world. To this effect, the abstracts of two official publications of the Association of Business Communication, Journal of Business Communication and Business Communication Quarterly, have been analyzed and compared in terms of structure and content according to models published in the specialized literature. The results show an irregular and inconsistent presentation of abstracts, a good number of them following no set pattern and thus lacking in important information for researchers. These findings suggest, first of all, that abstracts have a specific mission to fulfil and should not be disregarded; and, secondly, that journal guidelines for authors should be more explicit in their instructions on how to write and structure abstracts.

  20. Uncovering collective listening habits and music genres in bipartite networks

    Science.gov (United States)

    Lambiotte, R.; Ausloos, M.

    2005-12-01

    In this paper, we analyze web-downloaded data on people sharing their music library, that we use as their individual musical signatures. The system is represented by a bipartite network, nodes being the music groups and the listeners. Music groups’ audience size behaves like a power law, but the individual music library size is an exponential with deviations at small values. In order to extract structures from the network, we focus on correlation matrices, that we filter by removing the least correlated links. This percolation idea-based method reveals the emergence of social communities and music genres, that are visualized by a branching representation. Evidence of collective listening habits that do not fit the neat usual genres defined by the music industry indicates an alternative way of classifying listeners and music groups. The structure of the network is also studied by a more refined method, based upon a random walk exploration of its properties. Finally, a personal identification-community imitation model for growing bipartite networks is outlined, following Potts ingredients. Simulation results do reproduce quite well the empirical data.

    2006-01-01

    Full Text Available Introduction. Genre analysis is an approach to study communication patterns and thus it can be applied to the specific context of meetings. This research investigates the impact of genre analysis on the design of electronic meeting systems. Background. The primary goal of genre analysis is to understand how virtual communities use digital communication to collaborate. This knowledge is fundamental to inform IT design, particularly in areas where communication and informality are paramount. However, the research literature does not report any experiments where genre analysis has been used to inform electronic meeting system design. Problems. The paper tackles the following common problems found in current electronic meeting systems: (1 reduced organizational integration, neglecting many contextual cues and explaining factors necessary to make meeting outcomes usable within the organization; (2 lack of support to specific communities of users, stressing the dependency on a facilitator to configure and manage the technology; and (3 lack of support to meeting occurrences that span across long time periods. Conclusion. . The paper describes how genre analysis was used to develop electronic meeting systems for several organizations and meeting genres. It covers the complete design process, from genre elicitation to validation. The obtained results demonstrate that the genre approach produces electronic meeting systems focused on organizational integration, pre-configured to communities of users, supporting long-term usage and added organizational value.

    2015-11-01

    Full Text Available Genre-based instruction has been latterly a very common method used in language courses. In spite of the various research conducted on academic genres, there are still very few studies which examine the learners’ perceptions of genre-based pedagogy, particularly in courses like English for Specific Purposes (ESP. Therefore, the present study aimed at considering the Sophomore Business Management learners’ perspective on genre instruction in their ESP course, at the University of Tehran. The focuses of the present study were the focal genres of textbook and teaching method in terms of the content feature. The data was collected by means of both quantitative and qualitative instruments which were subject to both statistical analysis and constant comparative method of qualitative analysis. Results of the study revealed that the practice of genres were relevant to some of the learners’ subsequent academic and non-academic performance. Furthermore, the results regarding the questionnaire section indicated that a number of learners could apply the genre features and they were conscious of them. By and large, it was concluded that the explicit instruction together with the provision of more English-mediated content courses, for practices outside of the classroom, can have a higher impact on ESP programs.

    Energy Technology Data Exchange (ETDEWEB)

    Bayle, J

    1996-11-05

    Few studies have been carried out on the notion of gas-solid contact in ultra-rapid reactors. Both gas and solid move in the reactor and the contact can be directly estimated when using a chemical reaction such as cumene cracking. It`s a pure and light feedstock whose kinetics can be determined in a fixed bed. The study was carried out on a downflow ultra-rapid reactor (ID = 20 mm, length = 1 m) at the University of Western Ontario. It proved that the quench and the ultra-rapid separation of gas and solid must be carefully designed in the pilot plant. Cumene conversion dropped when reducing gas-solid contact, which led to push the temperature over 550 deg. C and increase the cat/oil ratio at 25 working at solid mass fluxes below 85 kg/m{sup 2}.s. Change of selectivity at very short residence time were also observed due to deactivation effects. Experiments made by Roques (1994) with phosphorescent pigments on the Residence Time Distribution of solids gave Hydrodynamic data on a cold flow copy of the pilot plant. Experiments made on packed bed gave kinetic data on the cracking of cumene. These data were combined to optimize a mono dimensional plug flow model for cumene cracking. (author)

    1998-03-01

    This thesis was carried out in the framework of fuel cycles studies in partnership with COGEMA; the aim is to determine physics parameters characterising Boiling Reactor Assemblies. Those reactors Firstly distinguish themselves from Pressurised Water Reactor by the boiling of the moderator in the core and secondary by the strong neutronics heterogeneity due to complex design. The diphasic mixture formed is characterised by the void fraction parameter. The loss of information, and neutronic studies characteristics of Boiling Water Reactors led us to make preliminary studies having in view to quantify the void fraction impact on the isotopics evolution. Studies on neutronics influence of assemblies and control rods from the immediate environment allows to define the cluster size to describe. The radial description optimisation with APOLLO-2 is necessary to improve the calculation performance and to reduce the errors coming from the modelization. The following points were studied: pellet radial discretization, clustering of cells characterized by a similar behaviour, options in flux spatial calculation (interface current formalism), self-shielding optimisation (specific to each isotopes). The three dimensional modelization with CRONOS-2 and the simplified accounting of the thermohydraulics / neutronics coupling done by a procedure developed and written during this thesis, allow an evaluation of axial distribution of void fraction, power and burn-up during the irradiation. The comparison with experimental analytic results of complete assembly and pin samples dissolutions allows the qualification of this procedure and confirms the necessity to take into account the void fraction axial variation during the evolution. The application of an automatic coupling with the DARWIN cycle code will allow a precise burnup calculation to be utilized in an industrial procedure. (author)

    Following on theoretical work already published, an indium-gallium radiation contour of the IRT nuclear reactor has been prepared, and represents a powerful new source of gamma-radiation. The first contour of this type ''RK-1'' was prepared on the IRT reactor at the Physics Institute of the Academy of Sciences of the Georgian SSR. The paper gives the activation calculations for indium-gallium alloy; the structural components of RK-1 and their arrangement in the reactor tank and the hot cell; the devise for feeding liquid and gaseous substances into the irradiation zone; and the conveyor for solid substances to be irradiated. When the IRT reactor is at a power of 2000 kW, the radiation strength of the contour is equivalent to that of a gamma-emitter having an activity of 20,000 g. Ra equivalent. The prospects for the use of the indium-gallium radiation contour for research and semi-industrial purposes are discussed. (author) [French] A la suite de la publication d'un ouvrage theorique, on a etabli autour du reacteur nucleaire IRT un circuit d'activation d'indium-gallium qui represente une nouvelle source de rayonnements gamma de grande intensite.

    2015-11-01

    Full Text Available The article analyzes a writer’s genre strategy based on the materials of A. Platonov’s short novels of the 1930s (“Th e Foundation Pit” [“Kotlovan”], “For future use” [“Vprok”], “Bread and reading” [“Hleb i chtenie”], “Juvenile sea” [“Uvenil’noe more”], “Dzhan”. These short novels became a link between his two novels “Chevengur” (1926—1928 and “Happy Moscow” (1933—1936. The comprehensive analysis of the short novels of the 1930s in the dialectics of genre development allows us to understand Andrei Platonov’s artistic world, the role of genre in the implementation of his creative idea, the specifi cs of genre thinking, and to identify the relationship between the genre and utopian/dystopian strategies of the writer. The article concludes that the short novels of the 1930s constitute a cycle and are united by a usual plot of “test”, the type of a hero (a worker-wanderer, the poetics of the conclusions. The recon-struction of the author’s model of the genre and its dynamics in the works of one of the distinguished writers of Russian and World literature of contemporary history leads to a deeper understanding of the artistic nature, role and genesis of the short novel in genre analysis of 20th century-literature

    Full Text Available The current study used event-related brain potentials (ERPs and behavioral measures to examine effects of genre awareness on sentence processing and evaluation. We hypothesized that genre awareness modulates effects of genre-typical manipulations. We manipulated instructions between participants, either specifying a genre (poetry or not (neutral. Sentences contained genre-typical variations of semantic congruency (congruent/incongruent and morpho-phonological features (archaic/contemporary inflections. Offline ratings of meaningfulness (n = 64/group showed higher average ratings for semantically incongruent sentences in the poetry vs. neutral condition. ERPs during sentence reading (n = 24/group; RSVP presentation at a fixed per-constituent rate; probe task showed a left-lateralized N400-like effect for contemporary vs. archaic inflections. Semantic congruency elicited a bilateral posterior N400 effect for incongruent vs. congruent continuations followed by a centro-parietal positivity (P600. While N400 amplitudes were insensitive to the genre, the latency of the P600 was delayed by the poetry instruction. From these results, we conclude that during real-time sentence comprehension, readers are sensitive to subtle morphological manipulations and the implicit prosodic differences that accompany them. By contrast, genre awareness affects later stages of comprehension.

    This report describes one study which contributed to the construction of the Monts d'Arree nuclear power station: EL-4. The reactor is cooled by a CO{sub 2} current provided by 3 turbo-blower groups. The priming vapour for the turbines is taken at the exit of the main CO{sub 2} - H{sub 2}O exchangers. The operation of EL 4 is based on a high degree of centralization of the controls which attributes an important role to the general regulation circuits. This general regulation includes in particular an internal blowing loop which controls the CO{sub 2} flow. The study of the control of this CO{sub 2} flow is made up of 3 parts: - analogue representation of the reactors cooling circuit and of the turbo blower unit. - first test campaign using the analogue computer describing the natural behaviour of the system in the absence of control. theoretical determination of the regulation factors; definition of the regulation using an analogue computer and second test campaign for recording the performances of the blowing loop. The 4. part of the report deals with the analogue study: analogue equations - development.

Au croisement de la sociologie, de l’anthropologie et de l’histoire, les différents articles analysent les pratiques concrètes de mesure pour tenter de comprendre ce qui se produit au cours de l’opération d’évaluation du danger sans préjuger de la nature de celui-ci. L’anthropologie a contribué à la réflexion sur l’infortune en s’intéressant aux temporalités de l’après : maladies, catastrophes, pandémies, etc. et en cherchant à rendre compte de l’expérience des victimes, de leur vie ordinaire bouleversée, de la recomposition du quotidien. Elle s’intéresse aussi aux autres types de mesures, les savoirs incorporés, qui reposent sur l’odorat, la vue ou le toucher et ceux qui ressortent d’une épistémologie « non ...

  1. La confrontation des genres au tribunal au Moyen Âge (XIVe-XVIe siècles. Une relecture des relations de couples en conflit

    Directory of Open Access Journals (Sweden)

    Martine Charageat

    2009-12-01

    Full Text Available La conflictualité conjugale analysée avec le concept de genre, et pas seulement en vue de vérifier l’application ou non du droit matrimonial par les juges d’église, rejoint le courant davantage socio-anthropologique que juridique de l’histoire du couple en Occident au Moyen Âge. Un souffle d’optimisme historiographique provient de travaux récents, dans un champ d’étude où l’on tardait encore à apprécier la capacité des femmes à ne pas subir de tristes situations conjugales, faites de violence, de misère sentimentale et sexuelle. Il n’empêche que le conflit, au moment de sa création, son récit devant le juge, les attentes des litigants quant à sa résolution obéissent à un rapport de force entre genres clairement distingués entre eux jusque dans le choix des normes, des arguments invoqués, de la rhétorique judiciaire déployée dans les procès. Même lorsque le couple agit par collusion, le dialogue avec le juge obéit aussi à des différences de genre.The analysis of matrimonial conflicts using the concept of gender, which goes beyond the verification of whether judges applied or not canonical law, draws more on socio-anthropological trends in the history of the married couple in the middle ages than on legal trends. The new historiographical optimism present in recent works testifies to how women were able to refuse some matrimonial situations despite the existence of domestic violence, forced sexual abstinence (impotence and limited sentimental exchanges with their husbands. Nonetheless, this article highlights how gender determined the nature of every matrimonial conflict and its description before the judge. Gender underwrote as well the expectations litigants had in using lawsuits, given the power relationship between the sexes, even when wives and husbands sought  a judicial separation by mutual agreement.

    Full Text Available L'article présente une relecture du premier volume de la Trilogie d’Auschwitz, Aucun de nous ne reviendra, de Charlotte Delbo dans une perspective du genre (dans le sens double de « genre littéraire » et de « gender » visant à analyser l’influence de la conscience d´être femme sur la mise en scène de la voix narrative ainsi que sur la présentation du monde concentrationnaire. Loin des généralisations stéréotypées, telles que la supposition d’une plus grande force morale dans le groupe des détenues féminines ou d’une plus grande solidarité entre les femmes l’article focalise les procédés narratifs et les images évoquées par le texte de Delbo qui sera comparé ensuite au récit L’espèce humaine de Robert Antelme. Dans la mesure où Charlotte Delbo et Robert Antelme s’obstinent à faire une histoire de leur expérience, il devient impossible d’associer leurs textes à un genre et, par conséquent, la lecture est contaminée par les effets d’une voix qui ne peut plus être située dans un cadre fixe ou un lieu concret. Ce « Je » qui parle appartient à un corps féminin ou masculin qui garde la mémoire traumatique et qui, en se transformant en un « nous », fonctionne comme un écran pour la souffrance et la mort des autres. Il reste alors à analyser les liens (secrets entre voix narrative, corps et genre, non pour rétablir le contexte biographique mais pour faire voir la naissance d’un sujet qui parle et qui, dans sa vulnérabilité, s’expose au regard des autres.

First, I characterize the computer and the internet as metamedia, incorporating previous genres of embodied communication as well as mass communication. Second, I describe genres as a variety of meta-communication, which serves to configure communication in the first place. In conclusion, I discuss whether and how a category of meta-genres might help to account for some distinctive features of the digital media environment.

    In this paper, Support Vector Machines (SVMs) are used for segmenting and indexing video genres based on only audio features extracted at block level, which has a prominent asset by capturing local temporal information. The main contribution of our study is to show the wide effect on the classification accuracies while using an hierarchical categorization structure based on Mel Frequency Cepstral Coefficients (MFCC) audio descriptor. In fact, the classification consists in three common video genres: sports videos, music clips and news scenes. The sub-classification may divide each genre into several multi-speaker and multi-dialect sub-genres. The validation of this approach was carried out on over 360 minutes of video span yielding a classification accuracy of over 99%.

  5. Making fictions sound real - On film sound, perceptual realism and genre

    2010-05-01

    Full Text Available This article examines the role that sound plays in making fictions perceptually real to film audiences, whether these fictions are realist or non-realist in content and narrative form. I will argue that some aspects of film sound practices and the kind of experiences they trigger are related to basic rules of human perception, whereas others are more properly explained in relation to how aesthetic devices, including sound, are used to characterise the fiction and thereby make it perceptually real to its audience. Finally, I will argue that not all genres can be defined by a simple taxonomy of sounds. Apart from an account of the kinds of sounds that typically appear in a specific genre, a genre analysis of sound may also benefit from a functionalist approach that focuses on how sounds can make both realist and non-realist aspects of genres sound real to audiences.

    2017-05-01

    Full Text Available This study investigated the collaborative genre-based effectiveness among the pre-service English teachers (PSETs. Data collection used the genre-based writing feedback observation upon its reflection and instruction and need analysis questionnaire. The data analysis used multivariate statistics method to generalize the writing tests. The findings showed that the PSETs’ feedback supported the interaction, accountability, and interdependence. These aspects were due to the collaborative participation in groups, in which the PSETs worked with the flexibility, entirely performed the quality, andcontributed in positive attitude during the meetings and assignments. The feedback emphasized the learning improvement within the formative reflection through the general linear model (GLM repeated measures analysis, where F=6,114 and p<0,01. This study concludes that the collaborative genre-based writing feedback has the positive response from the PSETs. The determinant ranges gains in between 85% to 90% after a series of genre-based writing lectures were conducted.

  9. Inference or enaction? The impact of genre on the narrative processing of other minds.

    Directory of Open Access Journals (Sweden)

    James Carney

    Full Text Available Do narratives shape how humans process other minds or do they presuppose an existing theory of mind? This study experimentally investigated this problem by assessing subject responses to systematic alterations in the genre, levels of intentionality, and linguistic complexity of narratives. It showed that the interaction of genre and intentionality level are crucial in determining how narratives are cognitively processed. Specifically, genres that deployed evolutionarily familiar scenarios (relationship stories were rated as being higher in quality when levels of intentionality were increased; conversely, stories that lacked evolutionary familiarity (espionage stories were rated as being lower in quality with increases in intentionality level. Overall, the study showed that narrative is not solely either the origin or the product of our intuitions about other minds; instead, different genres will have different-even opposite-effects on how we understand the mind states of others.

    2012-11-01

    Full Text Available In this paper, we discuss some issues involved in teaching and learning reading, especially schooling in visual literacy. We seek to observe the work developed with genres that combine verbal and visual languages, found in the reading activities of two high school textbook series for Portuguese language teaching. Our goal was to understand to what extent these activities contribute towards the development of reading skills needed to deal with the specificities of these genres. Therefore, we used the enunciative and discursive assumptions of the socio-historical approach of Bakhtin Circle, as well as the Social Semiotics perspective to understand multimodality. Data analysis revealed that the incidence of multimodal genres studied in the two textbook series is hardly representative. The didactic treatment these genres receive in reading activities does not favor the mobilization of specific reading skills and contributes little to students‟ visual literacy schooling.

    In recent years, several studies have explored the motivations for playing different game genres such as MMO (Yee, 2006a, 2006b) and FPS (Jansz & Tanis, 2007). Others have taken steps towards creating an integrated framework for use across genres (Sherry, Lucas, Greenberg, & Lachlan, 2006). Despite the strong gender bias of the game industry, however, none of these studies have tackled the issue of gender differences in motivations. This paper aims to fill this gap by exploring the relation b...

    Full Text Available This study aims to discuss how teaching and learning activities were carried out by using Genre based Approach in teaching writing descriptive text at junior high school. This study was conducted in the classroom of VII-1. Therefore, the appropriate design was qualitative research design. The subject of the study was the English teacher. To collect data, the researcher used observation and interview. The finding of the study described that the teaching and learning activities that were carried out by the teacher fulfilled the basic competencies. The teacher carried out the opening teaching activities by greeting, asking the students’ preparation during the lesson, checking the student’s attendance list, and informing the learning objective. The teacher carried out the main teaching activities by informing about how to write a descriptive text, giving, and asking opinions, eliciting the students’ understanding, prompting and directing to do exercises. The teacher carried out the closing teaching activities by directing the student to continue at home and eliciting the students’ reflection of what they could learn at that time.

    2015-07-01

    As children develop skills in writing across academic contexts, clinicians and educators need to have a fundamental understanding of typical writing development as well as valid and reliable assessment methods. The purpose of this study was to examine the progression of linguistic elements in school-age children's narrative and expository writing development. Narrative and expository writing samples produced by 89 children in Grades 2 through 4 were analyzed at the microstructure and macrostructure levels. Measures of receptive vocabulary, word-level reading, and reading comprehension were obtained. Exploratory factor analyses revealed 4 microstructure factors (e.g., productivity, grammatical complexity, grammatical accuracy, and lexical density) and 1 macrostructure factor (e.g., a combination of organization, text structure, and cohesion). Multivariate analyses of covariance with reading comprehension as a covariate showed that productivity and macrostructure were sensitive to grade-level and genre differences and that expository grammatical complexity was sensitive to grade-level differences. Findings are discussed in light of grade-level standards for narrative and expository writing and current practices in writing assessment. Multiple suggestions are offered for clinical and educational implications, and specific directions are provided for future research.

    2012-03-01

    This study assessed how problem video game playing (PVP) varies with game type, or "genre," among adult video gamers. Participants (n=3,380) were adults (18+) who reported playing video games for 1 hour or more during the past week and completed a nationally representative online survey. The survey asked about characteristics of video game use, including titles played in the past year and patterns of (problematic) use. Participants self-reported the extent to which characteristics of PVP (e.g., playing longer than intended) described their game play. Five percent of our sample reported moderate to extreme problems. PVP was concentrated among persons who reported playing first-person shooter, action adventure, role-playing, and gambling games most during the past year. The identification of a subset of game types most associated with problem use suggests new directions for research into the specific design elements and reward mechanics of "addictive" video games and those populations at greatest risk of PVP with the ultimate goal of better understanding, preventing, and treating this contemporary mental health problem.

  2. Socio-cognitive aspects of hedging in two legal discourse genres

    Directory of Open Access Journals (Sweden)

    Holly Vass

    2004-04-01

    Full Text Available While there are many studies on hedging in a wide variety of disciplinary discourses, the field of Law, to date, has been largely overlooked. Moreover, most research on hedging approaches the phenomenon from either a textual or pragmatic perspective, and tends to compare the same genre across disciplines. By contrast, the objective of this study was to analyse hedging in two legal written discourse genres, namely U.S. Supreme Court opinions and American law review articles, from a comprehensive, socio-cognitive, intra-disciplinary perspective. Due to the essential roles of intuition and hedging competence in the identification of hedges, qualitative data gathering and interpretation techniques were used. Results indicate that differences between the two genres can be linked to certain prototypical features of the genres themselves, particularly context and communicative purposes. Therefore, it is possible to postulate that hedging is in fact genre-specific, at least insofar as legal genres are concerned. Further comparative research must be done to determine if the same is true in other fields as well.

    Full Text Available Abstract The present study examined the effect of genre-based tasks on EFL learners' speaking performance and probed whether genre-based tasks may empower EFL learners to perform better on speaking tests. A further concern of the study was to explore whether the effect of genre-based tasks on speaking ability of EFL learners varied across different age groups, i.e. teenagers (13-16 years old and young adults (24-27 years old. To this end, some generic based consciousness-raising tasks (CRT were adapted from the model proposed by Benedict (2006 to develop control of a genre used as the treatment procedures. Two different speaking tests of different genres (e.g. recount, report, review, etc., used as pretest and posttest, were administered to 120 senior university students majoring in English language translation. The results indicated that consciousness-raising tasks significantly affected EFL learners' speaking performance. However, the effect of generic-based CRTs did not vary across different age groups. Overall, the findings provided empirical support for the facilitative effect of generic-based consciousness-raising tasks on speaking performance of EFL learners. The findings may promise implications for EFL speaking syllabuses and provide guidelines to designers to accommodate the insights derived from the genre-based instruction perspective.

    Full Text Available In this paper we propose the algorithm of automated definition of the genre type and semantic characteristics of poetic texts in Russian. We formulated the approaches to the construction of a joint (“two-dimensional” classifier of genre types and stylistic colouring of poetic texts, based on the definition of interdependence of the type of genre and stylistic colouring of the text. On the basis of these approaches the principles of formation of the training samples for the algorithms for the definition of styles and genre types were analyzed. The computational experiments with a corpus of texts of the Lyceum lyrics of A.S.Pushkin were implemented, which showed good results in determining the stylistic colouring of poetic texts and sufficient results in determining the genres. The proposed algorithms can be used for automation of the complex analysis of Russian poetic texts, significantly facilitating the work of the expert in determining their styles and genres by providing appropriate recommendations.

    with the help of comparing Khaghani Shervani and Abolhasan Tahami’s elegy by Naser Mohseniniya and Arezu Yazdanpanah Kermani. In Persian courtesy, elegy is often versified and it may have different genres, but the most frequently used genre up to the end of 8th century is the ode, and fragment genre, Refrain and compounding are next ranks. Among Khaghani’s elegies, twenty-one elegies are composed in ode genre, sixteen of which have row and five others do not have any row.   After ode, Fragment genre has more applicability in Khaghani’s Divan in elegies. Generally, he composed nineteen Fragments about the courtier and religious men. Khaghani also composed four composite-tie about his son mourning and government’s personnel. One thing to be noticed by poet about elegy is the proportion of verse with subject. Most of prosodic verses couldn’t be used in elegy. From the beginning of Persian poetry to the end of 8th century, Ramal poetical meter (faelaton foot is the most usable and Gharib poetical metre (faoulon foot is less usable one among others. In Khaghani’s Divan Ramal poetical meter with fifteen cases, the most usable poetical meter is elegy. After future, Mozare octagonal poetical meter (mafoulo faelato mafailo faelon and khafif poetical meter (faelaton mafaelon faelon are placed next with six cases.

Although Khaghani couldn’t hide his influence from the coming event, he also does not give up imagology. According to the conducted studies, one should say that Khaghani made nice images in elegy; images followed by formality, but its amount is less than Khaghani’s other odes. Simile

  12. Techniques d'inspection par ondes guidees ultrasonores d'assemblages brases dans des reacteurs aeronautiques =

    Comot, Pierre

    L'industrie aeronautique, cherche a etudier la possibilite d'utiliser de maniere structurelle des joints brases, dans une optique de reduction de poids et de cout. Le developpement d'une methode d'evaluation rapide, fiable et peu couteuse pour evaluer l'integrite structurelle des joints apparait donc indispensable. La resistance mecanique d'un joint brase dependant principalement de la quantite de phase fragile dans sa microstructure. Les ondes guidees ultrasonores permettent de detecter ce type de phase lorsqu'elles sont couplees a une mesure spatio-temporelle. De plus la nature de ce type d'ondes permet l'inspection de joints ayant des formes complexes. Ce memoire se concentre donc sur le developpement d'une technique basee sur l'utilisation d'ondes guidees ultrasonores pour l'inspection de joints brases a recouvrement d'Inconel 625 avec comme metal d'apport du BNi-2. Dans un premiers temps un modele elements finis du joint a ete utilise pour simuler la propagation des ultrasons et optimiser les parametres d'inspection, la simulation a permis egalement de demontrer la faisabilite de la technique pour la detection de la quantite de phase fragile dans ce type de joints. Les parametres optimises sont la forme de signal d'excitation, sa frequence centrale et la direction d'excitation. Les simulations ont montre que l'energie de l'onde ultrasonore transmise a travers le joint aussi bien que celle reflechie, toutes deux extraites des courbes de dispersion, etaient proportionnelles a la quantite de phase fragile presente dans le joint et donc cette methode permet d'identifier la presence ou non d'une phase fragile dans ce type de joint. Ensuite des experimentations ont ete menees sur trois echantillons typiques presentant differentes quantites de phase fragile dans le joint, pour obtenir ce type d'echantillons differents temps de brasage ont ete utilises (1, 60 et 180 min). Pour cela un banc d'essai automatise a ete developpe permettant d'effectuer une analyse similaire

    1994-05-01

    In this work, we looked for the error sources in the calculation of the isothermal temperature coefficient for light water lattices. We studied three fields implied: the nuclear data, the calculation methods and the temperature coefficient measurement. About the measurement, we pointed out the difficulties of he interpretation. So we used an indirect approach by the mean of critical states at various temperatures. In that way, we can say that if the errors in the effective multiplication factor are constants with temperature then the temperature coefficient is correctly calculated. We studied the neutronic influence of light water models which are used in the thermal scattering cross-section computation. This cross-section determines the thermalization process of neutrons. We showed that the actual model (JEF2) is satisfactory of the needs of the reactors physics. Concerning the majors isotopes ({sup 235}U, {sup 238}U, {sup 239}Pu), the uncertainties on the nuclear data do not seem as a preponderant cause of errors, without to be totally negligible. We also studied, with the neutron transport code Apollo-2, the influence of difference approximations for cell calculation . The new possibilities of the code has been used to represent the critical experiments, particularly the improvement of the resonance self-shielding formalism. The calculation scheme adopted permits to remove partially the fundamental mode approximation by the mean of a two-dimensional transport calculation with the SN method, the axial leakage being treated as an absorption in DB{sup 2}{sub Z}. The agreement between theory and experiment is good both for the reactivity and the temperature coefficient. (author). 114 refs., 40 figs., 163 tabs., 1 append.

Six staff members in the immediate surrounding of the bare assembly were exposed to high neutron and ionising irradiation. Other two employees who were at some bigger distance were exposed to doses higher than permitted. This paper deals with the circumstances that caused the accident, status of the dosimetry, control and alarm systems. Individual exposure doses were estimated according to the calculated neutron flux values obtained from measuring the activities of personal belongings made of gold and copper as well as radioactive phosphorous from urine.

    The Service of the Reactor Siloe (CEA/DRN/DRE/SRS), fully aware of the abilities and knowledge of his teams in the field of research reactor operating, has undertaken a project of knowledge engineering in this domain. The following aims have been defined: knowledge capitalization for the installation in order to insure its perenniality and valorization, elaboration of a project for the aid of the reactor operators. This article deals with the different actions by the SRS to reach the aims: realization of a technical model for the operation of the Siloe reactor, development of a knowledge-based system for the aid for operating. These actions based on a knowledge engineering methodology, SAGACE, and using industrial tools will lead to an amelioration of the security and the operating of the Siloe reactor.

    This work deals with modelling, simulation and optimization of the coupling between nuclear reactors (PWR, modular high temperature reactors) and desalination processes (multiple effect distillation, reverse osmosis). The reactors considered in this study are PWR (Pressurized Water Reactor) and GTMHR (Gas Turbine Modular Helium Reactor). The desalination processes retained are MED (Multi Effect Distillation) and SWRO (Sea Water Reverse Osmosis). A software tool: EXCELEES of thermodynamic modelling of coupled systems, based on the Engineering Algebraic Equation Solver has been developed. Models of energy conversion systems and of membrane desalination processes and distillation have been developed. Based on the first and second principles of thermodynamics, these models have allowed to determine the optimal running point of the coupled systems. The thermodynamic analysis has been completed by a first economic evaluation. Based on the use of the DEEP software of the IAEA, this evaluation has confirmed the interest to use these types of reactors for desalination. A modelling tool of thermal processes of desalination in dynamic condition has been developed too. This tool has been applied to the study of the dynamics of an existing plant and has given satisfying results. A first safety checking has been at last carried out. The transients able to jeopardize the integrated system have been identified. Several measures aiming at consolidate the safety have been proposed. (O.M.)

    {beta}{sub eff}, which represents the effective delayed neutron fraction, is an important parameter for the reactor nominal working as well as for studies of its behaviour in accidental situation. In order to improve the safety of nuclear reactors, we propose here to validate its calculation by using the ERANOS code with ERALIB1 library and by taking into account all the fission process physics through the {nu} energy dependence. To validate the quality of this calculation formalism, we calculated uncertainties as precisely as possible. The experimental values of {beta}{sub eff}, as well their uncertainties, have also been re-evaluated for consistency, because these `experimental` values actually contain a calculated component. We therefore obtained an entirely coherent set of calculated and measured {beta}{sub eff}. The comparative study of the calculated and measured values pointed out that the JEF2.2 {nu}{sub d} are already sufficient because the (E-C)/C are inferior to 3 % in average and in their uncertainly bars. The experimental uncertainties, even if lightly superior to those previously edited, remain inferior to the uncertainties of the calculated values. This allowed us to fit {nu}{sub d} with {beta}{sub eff}. This adjustment has brought an additional improvement on the recommendations of the {nu}{sub d} average values, for the classical scheme (thermal energy, fast energy) and for the new scheme which explains the {nu}{sub d} energy dependence. {beta}{sub eff}, for MOX or UOX fuel assemblies in thermal or fast configurations, can therefore be obtained with an uncertainty due to the nuclear data of about 2.0 %.

    The aim of this technical meeting is the improvement of the existing nuclear data and the production of new data of interest for the upstream and downstream of the fuel cycle (enrichment, fabrication, management, storage, transport, reprocessing), for the industrial reactors, the research reactors and the new reactor concepts (criticality, dimensioning, exploitation), for the instrumentation systems (external and internal sensors), the radioprotection, the residual power, the structures (neutron bombardment effect on vessels, rods etc..), and for the activation of steel structures (Fr, Ni, Co). The expected result is the collection of more reliable and accurate data in a wider spectrum of energies and temperatures thanks to more precise computer codes and measurement techniques. This document brings together the communications presented at this meeting and dealing with: the process of production and validation of nuclear data; the measurement facilities and the big international programs; the users needs and the industrial priorities; the basic nuclear data (BND) needs at Cogema; the expression and evaluation of BND; the evaluation work: the efficient cross-sections; the processing of data and the creation of activation libraries; from the integral measurement to the qualification and the feedback on nuclear data.

    the work on this subject has not been previously published. (author) [French] Le Laboratoire scientifique de Los Alamos, exploite par l'Universite de Californie pour la Commission de l'energie atomique des Etats-Unis, s'occupe depuis plus de vingt ans de l'etude, de la mise au point et de la construction de quatre types de reacteurs nucleaires: reacteurs de recherche, reacteurs de puissance, reacteurs pour la propulsion des fusees et assemblages critiques. Le Groupe des essais non destructifs collabore a presque tous les projets et travaux du Laboratoire. Le memoire decrit quelques-unes des methodes inedites d'essais non destructifs qui y ont ete mises au point et sont appliquees dans le cadre du programme de reacteurs. Le reacteur de puissance experimental LAMPRE est fonde sur l'utilisation d'une solution de phosphate d'uranium a haute temperature. Cette solution est tres corrosive et toutes les parties en contact avec elle ont un revetement en or. On a eu recours a des techniques radiographiques speciales pour controler l'or pendant le processus de laminage d'un lingot coule. On a procede de la meme maniere a l'inspection des soudures. Une methode d'inspection fondee sur les variations de potentiel aux electrodes a ete mise au point, pour la detection d'impuretes sur les surfaces d'or. Le reacteur experimental au plutonium fondu LAPRE est fonde sur l'utilisation de plutonium metallique, sous forme liquide plutot que sous forme solide, comme combustible. Le combustible est contenu dans des capsules en tantale. On a eu recours a des methodes non destructives pour verifier le bon etat du metal de base et des soudures pendant la fabrication des capsules, ainsi que pour controler les capsules remplies de plutonium avant, pendant et apres les essais de fusion et solidification. L'essai d'une pompe a plutonium fondu a ete suivi par des methodes radiographiques, en utilisant notamment un circuit ferme de television a rayons gamma. Pour le reacteur experimental a tres haute
