Un videojoc és un joc que involucra a algú la interacció amb un espai d’efectesvisuals en un dispositiu electrònic amb una pantalla i una sèrie de perifèrics quepermeten la interacció. Aconseguir el màxim de realisme es un dels objectiusprincipals dels dissenyadors de videojocs i per això cal integrar en un mateix entorndiferents components tals com: un motor de render, un motor de física, un d’intel•ligència artificial, un motor de so, etc. El motor de so és un dels elements clau delvideojoc, ja que el motor de render pot tenir molts bons gràfics, però sense un sistemade so amb posicionament 3D no es pot apreciar ni gaudir del videojoc en la sevatotalitat.L’objectiu d’aquest projecte és integrar dins del motor gràfic de treball (Ogre3D) un motor de so i convertir el motor de render actual en un motor de videojocs en fase beta.L’objectiu principal d’aquest projecte és implementar un sistema de so completamentintegrat amb la plataforma de Render Ogre3D que permeti de forma senzilla i intuïtivades d’un model de classes més abstracte la fàcil programació dels sons dins delsistema de render.El pla de treball definit per poder assolir els objectius, es divideix en dues fases: fase d’estudi previ on coneixerem les eines que necessitarem per treballar. Entre elles elmotor de render Ogre3D i la fase d’implementació, on ens centrem en els punts d’anàlisi de requeriments, del disseny i de la implementació per a poder integrar les llibreries d’àudio a l’aplicació de la qualpartim (les llibreries de render creades per GameTools)

Esta investigación pretende abordar el estudio del juego en el ámbito teatral, intentando reconocer los vínculos que pudiera haber entre el universo de la escena y el lúdico. La base teórica estudiada sobre el juego serán las fuentes primarias de la construcción lúdica: Johan Huizinga, y Roger Caillois y como referente principal del análisis del signo teatral tomaré a Tadeusz Kowzan, historiador y semiólogo del teatro. Para documentar la práctica teatral, he seleccionado a Jacques Lecoq y Philippe Gaulier, además de la compañía británica Théâtre de Complicité, analizando muy particularmente su espectáculo Las tres vidas de Lucie Cabrol

The Franco-German axis has been a transcendent force behind the European integration ever since the early years of the EEC. Nevertheless, since the fall of the Berlin Wall in November 1989, the perception of a progressive distancing between France and Germany as far as the EU politics is concerned, has increased. There has not been a definitive break in Franco-German relations. However, the influence of the Franco-German axis in the EU has been reduced in the 90s. Finally, in the Nice IGC (December 2000), the misunderstandings of these two “big” states about their weight in the Council, almost caused the failure to conclude the Treaty of Nice, clearing the way for the Eastern enlargement. The traditional balance between France and Germany has been eroded. Germany has consolidated its role of leadership in the EU, and above all towards the candidate countries. The purpose of this paper is to analyse the fifth enlargement as one of the causes of the decline of the Franco-German axis as the motor of the process of European integration.

El present treball pretén modelitzar i simular el motor d’inducció trifàsic en règim transitori amb PSIM 6.0 Demo(la versió del programa que s’utilitza actualment a l’Escola Politècnica Superior de la UdG), però també s’estudia el model en règim permanent, per tal de comparar a nivell teòric els resultats dels dos règims. Primer cal entendre i implementar el model del motor d’inducció, i així obtenir l'esquema equivalent en règim transitori, per després poder-lo simular. Abans de dur a terme la simulació, cal obtenir els paràmetres del circuit equivalent del motor real per introduir-los al programa informàtic, amb la finalitat de tenir precisió en les respostes. Aquests valors s’obtindran mitjançant assajos necessaris al laboratori. Posteriorment, es fan simulacions i pràctiques reals amb el motor treballen en diferents condicions per veure el seu comportament, i així poder comparar els resultats de la simulació amb els valors reals. També s’implementa un estudi de la influencia dels paràmetres interns en el funcionament del motor. Així es podrà visualitzar i comparar les respostes de diferents variables en cadascunes de les simulacions que es duguin a terme. Finalment, seria interessant la introducció de la màquina d’inducció trifàsica actuant com a generador en la simulació.Aquest és un estudi en el qual se simula la màquina d'inducció trifàsic en règim transitori i en règim permanent mitjançant l'ús del PSIM, que és el programa informàtic de simulació

En el nostre treball final de carrera tindrem com objecte la millora de les prestacions d’un motor de 4T per a una motocicleta d’enduro. L’augment de potència s’aconseguirà des de diferents perspectives, variant el sistema d’admissió, el canvi de la distribució de les vàlvules de la culata o variant la lubrificació del pistó. Per realitzar l’objecte d’aquest treball utilitzarem com a base de l’estudi el motor de 4T de la FSE 450 del 2004 de GASGAS Motos SA. El motor de 4T utilitzat està orientat cap a una utilització d’enduro, per tant amb unes característiques de parell determinades. Partirem de l’anàlisi d’un motor amb sistema d’admissió per depressió (carburador convencional) idesprés instal·larem el sistema d’injecció indirecta monopunt. La millora també afectarà a l’estil de conducció de la motocicleta, per tant comentarem els resultats obtinguts des de dues perspectives: d’una conducció estàndard i una d’esportiva

The occurrence of negative values for Fukui functions was studied through the electronegativity equalization method. Using algebraic relations between Fukui functions and different other conceptual DFT quantities on the one hand and the hardness matrix on the other hand, expressions were obtained for Fukui functions for several archetypical small molecules. Based on EEM calculations for large molecular sets, no negative Fukui functions were found

Different procedures to obtain atom condensed Fukui functions are described. It is shown how the resulting values may differ depending on the exact approach to atom condensed Fukui functions. The condensed Fukui function can be computed using either the fragment of molecular response approach or the response of molecular fragment approach. The two approaches are nonequivalent; only the latter approach corresponds in general with a population difference expression. The Mulliken approach does not depend on the approach taken but has some computational drawbacks. The different resulting expressions are tested for a wide set of molecules. In practice one must make seemingly arbitrary choices about how to compute condensed Fukui functions, which suggests questioning the role of these indicators in conceptual density-functional theory

Linear response functions are implemented for a vibrational configuration interaction state allowing accurate analytical calculations of pure vibrational contributions to dynamical polarizabilities. Sample calculations are presented for the pure vibrational contributions to the polarizabilities of water and formaldehyde. We discuss the convergence of the results with respect to various details of the vibrational wave function description as well as the potential and property surfaces. We also analyze the frequency dependence of the linear response function and the effect of accounting phenomenologically for the finite lifetime of the excited vibrational states. Finally, we compare the analytical response approach to a sum-over-states approach

Background: Recent advances on high-throughput technologies have produced a vast amount of protein sequences, while the number of high-resolution structures has seen a limited increase. This has impelled the production of many strategies to built protein structures from its sequence, generating a considerable amount of alternative models. The selection of the closest model to the native conformation has thus become crucial for structure prediction. Several methods have been developed to score protein models by energies, knowledge-based potentials and combination of both.Results: Here, we present and demonstrate a theory to split the knowledge-based potentials in scoring terms biologically meaningful and to combine them in new scores to predict near-native structures. Our strategy allows circumventing the problem of defining the reference state. In this approach we give the proof for a simple and linear application that can be further improved by optimizing the combination of Zscores. Using the simplest composite score () we obtained predictions similar to state-of-the-art methods. Besides, our approach has the advantage of identifying the most relevant terms involved in the stability of the protein structure. Finally, we also use the composite Zscores to assess the conformation of models and to detect local errors.Conclusion: We have introduced a method to split knowledge-based potentials and to solve the problem of defining a reference state. The new scores have detected near-native structures as accurately as state-of-art methods and have been successful to identify wrongly modeled regions of many near-native conformations.

Before the Civil War (1936-1939), Spain had seen the emergence offirms of complex organizational forms. However, the conflict andthe postwar years changed this pattern. The argument put forwardin this paper is based on historical experience, the efforts willbe addressed to explain the development of Spanish entrepreneurshipduring the second half of the twentieth century. To illustrate thechange in entrepreneurship and organizational patterns among theSpanish firms during the Francoist regime we will turn to the caseof the motor vehicle industry.

The Spanish automobile industry had a late start. Although the country proved capable of short production runs of high-quality vehicles during the first third of the century it never managed to build up its own industry, unlike Great Britain, France, or Italy. What then, were the critical shortcomings that prevented the establishment of large Spanish motor manufacturers? Put another way, why did all of the companies set up during the first half-century fail to survive? This paper attempts to shed some light on these questions, employing a wide-ranging analysis of both internal and external factors affecting the industry. A feeble internal market, lack of resources and production factors are usually adduced as reasons, as are Spain's general economic backwardness and the role played by the public authorities. However, this paper mainly focuses on the internal factors concerning company strategy and organisation. A comparison with the Italian case helps put the traditional arguments in proper perspective and highlights those covering business strategies. Finally, we argue that a broad range of factors needs to be analysed to fully understand why Spain failed to establish a motor industry.

In 1952 F. Riesz and Sz.Nágy published an example of a monotonic continuous function whose derivative is zero almost everywhere, that is to say, a singular function. Besides, the function was strictly increasing. Their example was built as the limit of a sequence of deformations of the identity function. As an easy consequence of the definition, the derivative, when it existed and was finite, was found to be zero. In this paper we revisit the Riesz-N´agy family of functions and we relate it to a system for real numberrepresentation which we call (t, t-1) expansions. With the help of these real number expansions we generalize the family. The singularity of the functions is proved through some metrical properties of the expansions used in their definition which also allows us to give a more precise way of determining when the derivative is 0 or infinity.

We propose a model and solution methods, for locating a fixed number ofmultiple-server, congestible common service centers or congestible publicfacilities. Locations are chosen so to minimize consumers congestion (orqueuing) and travel costs, considering that all the demand must be served.Customers choose the facilities to which they travel in order to receiveservice at minimum travel and congestion cost. As a proxy for thiscriterion, total travel and waiting costs are minimized. The travel costis a general function of the origin and destination of the demand, whilethe congestion cost is a general function of the number of customers inqueue at the facilities.
