A SIM, Subscriber Identity Module, is the removable circuit board found in a modern cellular phone. It carries the network identity information and is a type of smart card which can also be found on payment cards (EMV), ID cards and so on. A smart card is basically a small computer, providing a safe and controlled execution environment. Historically smart card software was very hardware dependent and mostly developed by the manufacturers themselves. With the introduction of the open Java Card standard created by Sun Microsystems (Oracle) this was meant to change. However, information still remains scattered and is hard to obtain. This paper is meant to serve both as an introduction to the field and also as a good foundation for future studies. It begins with a theoretical discussion about smart card hardware and software architectures, network standards in the context of SIM cards, typical applications, coming trends and technologies and ends off with an overview of the Java Card standard. The following section discusses the supplied example SIM card application coupled with an introduction how to use the Gemalto Developer Suite for application development and testing. The paper ends with an extensive appendix section going in depth about some of the more important subjects.

Dans ce travail nous étudions les propriétés arithmétiques et statistiques d'une nouvelle classe de fonctions de comptage des chiffres appelées fonctions digitales restreintes. Nous présentons tout d'abord les principales propriétés des suites engendrées par une substitution ou un $q$-automate ainsi que la suite célèbre de Thue-Morse et ses généralisations, puis nous comparons ces notions avec celle de fonction digitale restreinte.Nous étudions ensuite les sommes d'exponentielles associées à ces fonctions digitales restreintes ainsi que leur application d'une part à l'étude de la répartition modulo 1 des fonctions digitales restreintes et d'autre part à l'étude des propriétés statistiques des suites arithmétiques définies par des fonctions digitales restreintes.Dans la dernière partie de ce travail on étudie la représentation géométrique de ces sommes d'exponentielle à la lumière des travaux antérieurs de Dekking et Mendès-France ce qui nous conduit à énoncer plusieurs problèmes ouverts. / In this work we study the arithmetic and statistic properties of a new class of digital counting functions called restricted digital functions. We first present the main properties of sequences generated by a substitution or a $q$-automate followed by presenting the famous Thue-Morse sequence and its generalizations, then we compare these notions with the one of the restricted digital function.We then study the exponential sums associated with these restricted digital function and their implementation on the one hand to the study of uniform distribution modulo 1 of these restricted digital functions and on the other, to the study of the statistical properties of the arithmetic sequences defined by restricted digital functions.In the last part of this work we study the geometric representation of these exponential sums in the light of previous works of Dekking and Mendès-France which leads us to announce several open problems.

Dans son preprint, M. Bruno Kahn a construit une suite spectrale par rang en utilisant la méthode catégorique. Cette suite spectrale est construit par une filtration de la catégorie des modules sans-torsion de type fini d'un anneau intègre A ce qui explique le nom : suite spectrale par rangs. Cette suite spectrale converge vers les groupes d'homologies de la Q-construction de la catégorie de A-modules sans torsion de type fini et elle été utilisé par Quillen pour prouver que les K-groupes sont de génération finie pour anneau d'intègres d'un corps de nombres. Notre but de cette thèse est de calculer le différentiel de la suite spectrale par rangs qui peut servit comme une première étape d'une idée générale d'unifier les calculs de rangs des K-groupes de la courbe sur un corps fini (G. Harder) et la courbe arithmétique (A. Borel). Pour gagner ça, nous étudions le foncteur cellulaire (connexe) et les constructions de Grothendieck en détail, en particulier ses propriétés homotopiques. En utilisant ça, nous pouvons mettre le différentiel dans certain triangles distingués de foncteurs sur une catégorie, puis nous réalisons ces foncteurs explicits en langages d'immeuble de Tits, module de Steinberg et symbole modulaire au sens d'Ash-Rudolph. Nous avons aussi obliger de fabriquer un autre symbole : le symbole étendu pour étudier l'homologie de la suspension d'immeuble de Tits, mais nous montons que ce symbole est équivalent que symbole modulaire. / Bruno Kahn has constructed a rank spectral sequence by using a purely categorical approach. This spectral sequence was derived by using a filtration of the category of torsion-free modules over integral domain by ranks and hence the name: rank spectral sequence. This spectral sequence converges to the homology groups of the Q-construction over the category of finitely generated torsion-free modules over an integral ring. Quillen used it in the proof of the finite generation of K-groups of rings of integers. Our goal in this thesis is to calculate the differential of the rank spectral sequence. We believe that this is a first step towards a much bigger project, that is, to unify the calculation of the ranks of K-groups of curves over a finite field (result of G. Harder) and of arithmetic curves (result of A. Borel).To achieve our goal, we put the differential in certain distinguished triangles of coefficients/functors over some categories, and make these functors explicit in terms of Tits building and Ash-Rudolph's modular symbols. To accomplish this, we shall use Quillen's categorical homotopy theory intensively and introduce the notion of extended (modular) symbols which is equivalent to Ash-Rudolph's via the suspension of Tits buildings.

Cette thèse contient des contributions originales à la théorie du Contrôle Optimal en temps discret et en horizon infini du point de vue de Pontryagin. Il y a 5 chapitres dans cette thèse. Dans le chapitre 1, nous rappelons des résultats préliminaires sur les espaces de suites à valeur dans et des résultats de Calcul Différentiel. Dans le chapitre 2, nous étudions le problème de Contrôle Optimal, en temps discret et en horizon infini avec la contrainte asymptotique et avec le système autonome. En utilisant la structure d'espace affine de Banach de l'ensemble des suites convergentes vers 0, et la structure d'espace vectoriel de Banach de l'ensemble des suites bornées, nous traduisons ce problème en un problème d'optimisation statique dam des espaces de Banach. Après avoir établi des résultats originaux sur les opérateurs de Nemytskii sur les espaces de suites et après avoir adapté à notre problème un théorème d'existence de multiplicateurs, nous établissons un nouveau principe de Pontryagin faible pour notre problème. Dans le chapitre 3, nous établissons un principe de Pontryagin fort pour les problèmes considérés au chapitre 2 en utilisant un résultat de Ioffe-Tihomirov. Le chapitre 4 est consacré aux problèmes de Contrôle Optimal, en temps discret et en horizon infini, généraux avec plusieurs critères différents. La méthode utilisée est celle de la réduction à l'horizon fini, initiée par J. Blot et H. Chebbi en 2000. Les problèmes considérés sont gouvernés par des équations aux différences ou des inéquations aux différences. Un nouveau principe de Pontryagin faible est établi en utilisant un résultat récent de J. Blot sur les multiplicateurs à la Fritz John. Le chapitre 5 est consacré aux problèmes multicritères de Contrôle Optimal en temps discret et en horizon infini. De nouveaux principes de Pontryagin faibles et forts sont établis, là-aussi en utilisant des résultats récents d'optimisation, sous des hypothèses plus faibles que celles des résultats existants. / This thesis contains original contributions to the optimal control theory in the discrete-time framework and in infinite horizon following the viewpoint of Pontryagin. There are 5 chapters in this thesis. In Chapter 1, we recall preliminary results on sequence spaces and on differential calculus in normed linear space. In Chapter 2, we study a single-objective optimal control problem in discrete-time framework and in infinite horizon with an asymptotic constraint and with autonomous system. We use an approach of functional analytic for this problem after translating it into the form of an optimization problem in Banach (sequence) spaces. Then a weak Pontyagin principle is established for this problem by using a classical multiplier rule in Banach spaces. In Chapter 3, we establish a strong Pontryagin principle for the problems considered in Chapter 2 using a result of Ioffe and Tihomirov. Chapter 4 is devoted to the problems of Optimal Control, in discrete time framework and in infinite horizon, which are more general with several different criteria. The used method is the reduction to finite-horizon initiated by J. Blot and H. Chebbi in 2000. The considered problems are governed by difference equations or difference inequations. A new weak Pontryagin principle is established using a recent result of J. Blot on the Fritz John multipliers. Chapter 5 deals with the multicriteria optimal control problems in discrete time framework and infinite horizon. New weak and strong Pontryagin principles are established, again using recent optimization results, under lighter assumptions than existing ones.

Euphonium concertos and similar masterworks for euphonium have been recorded, written about, analyzed, and discussed at length numerous times in recent years. Unfortunately, the most frequently studied and performed euphonium solos have been almost completely ignored in this regard. These works are useful for performance by the undergraduate-level euphonium player. Solos in this category are played by strong high school players and undergraduate euphonium students all over the world. These solos receive countless performances and play a crucial role in the development of young euphonium players, yet have never received attention in the form of a published pedagogical guide. The pieces of greater difficulty and substantial length have received more attention for obvious reasons, but solo pieces most useful for the developing euphoniumist need to be analyzed and discussed on a pedagogical level. This paper is a pedagogical guide to commonly played euphonium solos by the undergraduate level student. The three pieces used in this study are Sonatina by Warner Hutchison, Sonata for Unaccompanied Euphonium by Fred Clinard, and Lyric Suite by Donald White. Pertinent background information about each piece is presented in order for the reader to understand the historical context in which it was written. A list of relevant information and minimum performance skills (instrumentation, length, range, articulation skills, etc.) are included for each selection. An analysis of particular sections of each piece are presented for the reader to adequately grasp concepts and practice ideas that are explained, although the bulk of analysis is of a pedagogical nature. The main body of the paper focuses on assisting the reader with ways to approach this solo literature in daily practice as well as effective performance ideas. Particularly troublesome areas of each piece are identified and strategies to overcome common pitfalls and performance errors are noted.

The master’s thesis deals with modelling of various architectures of hybrid powertrains for three vehicle sizes in GT-SUITE and compares them in daily commuting operating mode. On top of making of the hybrid vehicle simulation models, control algorithms had to be created to manage the energy split between the internal combustion engine and the electric motor for each of the architectures. Routes to work and back were logged using the GPS and postprocessed to obtain the speed and the road grade profiles. Resulting data was used as an input in simulations of daily commuting. To compare all hybrid powertrain architectures, fuel economy and electricity consumption were evaluated for WLTP and daily commuting operating modes. Finally, the environmental impact of each topology was assessed based on an estimation of corresponding well-to-wheel emissions.

This thesis solves the problem of generating random numbers on low-power devices. Author describes possible ways of generating and implements selected generators of (pseudo)random numbers on MSP430F5438A. 4 generators were added by the enhancement of one of them and a new generator was created, using the phenomenon of temperature change in the surroundings. For each generator, test sequences were generated and these sequences were tested by the Dieharder, STS-NIST, and Visual Test. The output of the thesis is the functional implementation of the generators, their testing by statistical methods and their comparison between each other.

The lecture was presented on November 18, 1991. This presentation focused on the only two compositions for solo flute and orchestra by Ernest Bloch. Written during the last three years of the composer's life, the pieces are representative of his last style period. While Suite Modale is neobaroque in style, Two Last Poems is much more subjective. Together they represent a synthesis of many of the stylistic characteristics of Ernest Bloch. The musical parameters discussed included form, melody, texture, rhythm, harmony, and expressive devices.
