Forster, Lou. "Page à la main. ː : Lucinda Childs et les pratiques de danse lettrée". Electronic Thesis or Diss., Paris, EHESS, 2024. http://www.theses.fr/2024EHES0015.
Texto completoLucinda Childs is a major figure in twentieth-century dance. In the early 1960s, she was one of the founding members of the Judson Dance Theater, a group of dancers, choreographers, artists and composers in New York City who reinvigorated dance forms and practices. With the establishment of her company in 1973, she emerged as one of the leading figures of American minimal dance and postmodern dance, while collaborating from the 1980s onward with major ballet companies in Europe and the United States. Whether with her own company, with repertory dance companies, or at Judson, literacy plays a crucial role in the conceiving, embodying, and performing of her dances. Through an anthropological investigation within dance studios, Lou Forster demonstrates that the technical gesture of dancing, page in hand, is constructed at the intersection of two parallel histories. In the 1950s, John Cage and Merce Cunningham devised a range of reading and writing practices in order to oppose, divert and reconfigure academic methods in which literacy serves as a foundation to establish disciplinary divisions and hierarchies. This neo-avant-garde approach played a crucial role at Judson. Among the members of this group, Childs was one of the choreographers who paid the most attention to these literacy practices, as they tied in with a lesser-known aspect of her dance training. From 1955 to 1962, she studied modern dance within the extensive network of the German diaspora in New York. Specifically, she attended the school run by the choreographer Hanya Holm (1893-1992), where an Americanised form of dance of expression (Ausdruckstanz) was taught. There Childs discovered Kinetography Laban or Labanotation, the system of analysing and writing movement developed by the Austro-Hungarian choreographer Rudolf Laban (1879-1958), in which dancers rehearse with page in hand. Fifteen years later she turned toward this literacy event, unusual for the dance world, to work with her company. Art history and dance history dissociated these two aspects of choreographic modernity when, from 1933, part of the dance of expression became involved with the Nazi regime. In the United States, the myth of the originality of American Modern dance began to take shape, further emphasized during the Cold War. Childs' unique position in this connected history meant that graphic practices became a matrix for postmodernism. Since 1973, she embraced all canonical techniques of Western dance, moving over the years from dance of expression to pedestrian activities, to Neoclassical and then to the Baroque. Positioning herself as an appropriationist, she developed a historical and critical perspective on these borrowed techniques. In her pieces, she seeks to bring together practices, genres and histories of dance that have been separated and disjointed, crafting a genuine poetics of relation

Texto completoIn this thesis we study the problems of regularity of three-dimensional minimal cones and sets in l'espace Euclidien de dimension 4In the first part we study the Hölder regularity for minimal cones of dimension 3 in l'espace Euclidien de dimension 4. Then we use this for showing that there exists a local diffeomorphic mapping between a minimal cone of dimension 3 and a minimal cone of dimension 3 of type P, Y or T, away from the origin. The techniques used here are the same as the ones for the regularity of two-dimensional minimal sets. We construct some competitors to reduce to the known situation of two-dimensional minimal sets in l'espace Euclidien de dimension 3.In the second part, we use the first part to give somme results of the Hölder regularity for three-dimensional minimal sets in l'espace Euclidien de dimension 4. We interested also in Mumford-Shah minimal sets and we get a result of the existence of a T-point

Texto completoIn this thesis, we will study some topics related to minimal surfaces in three-dimensional homogeneous manifolds. The first part is devoted to the study of non-positively curved Ricci surfaces with catenodial ends. The idea comes from a famous theorem of Huber. In the first place, we give a definition of catenoidal end for non-positively curved Ricci surfaces with finite total curvature. Secondly, we develop a tool which can be regarded as an analogue of the Weierstrass data. By using this tool, we get some classification results and some non-existence results for non-positively curved Ricci surfaces of genus zero with catenoidal ends. In the end of Chapter 2, we also prove an existence result for non-positively curved Ricci surfaces of arbitrary positive genus with finite many catenoidal ends.In the second part of this thesis, we concern about minimal surfaces in a three-dimensional metric Lie group widetilde{E(2)}, which is the universal covering of the group of rigid motions of Euclidean plane endowed with a left-invariant Riemannian metric. Firstly, a result of Patrangenaru describes the left-invariant metrics as a two-parameter family of metrics. Then we take advantage of a Weierstrass-type representation due to Meeks, Mira, Pérez and Ros to construct a one-parameter family of helicoidal minimal surfaces in widetilde{E(2)} as well as a one-parameter family of minimal annuli which are properly embedded in widetilde{E(2)}. In the end, by a discussion of the limit case of the second family of surfaces, we obtain a new proof of a half-space theorem for minimal surfaces in widetilde{E(2)}

Texto completoIn this thesis, we are interested in harmonic morphisms between Riemannian manifolds (Mm, g) and (Nn, h) for m > n. Such a smooth map is a harmonic morphism if it pulls back local harmonic functions to local harmonic functions: if ƒ : V → ℝ is a harmonic function on an open subset V on N and Φ-1(V) is non-Empty, then the composition ƒ ∘ Φ : Φ-1(V) → ℝ is harmonic. The conformal transformations of the complex plane are harmonic morphisms. In the late 1970's Fuglede and Ishihara published two papers ([Fu]) and ([Is]), where they discuss their results on harmonic morphisms or mappings preserving harmonic functions. They characterize non-Constant harmonic morphisms F : (M,g) → (N,h) between Riemannian manifolds as those harmonic maps, which are horizontally conformal, where F horizontally conformal means : for any x ∈ M with dF(x) ≠ 0, the restriction of dF(x) to the orthogonal complement of kerdF(x) in TxM is conformal and surjective. This means that we are dealing with a special class of harmonic maps
Cubides, Kovacsics Pablo. "Définissabilité dans les structures C-minimales". Paris 7, 2013. http://www.theses.fr/2013PA077247.
Texto completoThis thesis is a contribution to the study of definable sets in C-minimal structures. In chapter 1, an exposition of fundamental properties of C-minimal structures is given. Chapter 2 is devoted to a revision of Haskell and Macpherson's work, who proved a cell decomposition theorem for C-minimal structures together with the well-behavior of topological dimension for definabie sets. A variant of the definition of 1-cells is provided together with separation of proofs about continuity of definable functions and the well-behavior of topological dimension. Chapter 3 splits in four parts. In section 1, the study of definable functions is further developed. In particular, we consider definable locally constant functions from M to its canonical tree T. As corollaries we finc applications to algebraically closed valued fields and a description of definabie subsets of T in one variable, the latter being the content of section 2. In section 3, we examine 1-types over models. Some partial results on omitting types and orthogonality are provided. Finally, section 4 is a joint work with Françoise Delon. We study externally definable sets in algebraically closed fields of residue characteristic 0 (which are in particular C -minimal). We characterize those elementary pairs of algebraically closed valued fields of residue characteristic 0 (M,N) such that if ail 1-types over M realized in N are definable then ail types over M realized in N are definabie
Younes, Rami. "Surfaces minimales dans des variétés homogènes". Thesis, Tours, 2009. http://www.theses.fr/2009TOUR4032/document.
Texto completoThis doctoral thesis deals with minimal surface theory in two homogeneous manifolds, namely, R3 and PSL2(R). In R3, given a tiling T of the plane by straight edge polygons, which is invariant by two independent translations, we construct a family of embedded triply periodic minimal surfaces which desingularizes T ×R. For this purpose, inspired by the work of Martin Traizet, we open the nodes of singular Riemann surfaces to glue together simply periodic Karcher saddle towers, each placed at a vertex of the tiling in such a way that its wings go along the corresponding edges of the tiling ending at that vertex. On the other hand, in PSL2(R) we study minimal graphs and we furnish many invariant examples. We derive gradient estimates for solutions of the minimal surface equation in the underlying space and we study convergence of monotone sequences of solutions. Finally, we extend to PSL2(R) a result of Jenkins and Serrin who provide a necessary and sufficient condition for the solvability of the Dirichlet problem of the minimal surface equation in R3, with infinite data over boundary arcs of a convex bounded region
Gohara, Kai. "Il y a de l'image : Maurice Blanchot et l'image minimale de la littérature". Paris 7, 2007. http://www.theses.fr/2007PA070012.
Texto completo"Speaking (writing) is not seeing", said Maurice Blanchot (1907-2003). It is not an act of seeing but getting engaged with the "image". However, what is this strange sort of "image", which is both separated from "seeing" and related to "speaking (writing)"? If Blanchot often mentions the "fascination" of the "image" in his texts about literature in spite of his critique of the opti-centric idea of literature, then what does this mean in fact? It is well known that Blanchot presented an impressive concept named the "resemblance of cadavers" in his essay on the image: "Two Versions of the Imaginary". What matters for us is not just to extract and develop this concept as such but to examine and elucidate the very concept as fundamentally supporting Blanchot's primary idea of literature. The present study proposes to analyze Blanchot's writings in the forties and fifties from this perspective. In the first place, we explore these essays what explicitly treat of the question on the image, in order to reveal an immanent logic of the "resemblance of cadavers". The second part, in which the notion of "figure" serves as a guiding thread, is devoted to demonstrate our central argument about the image as literary language. All theses analyses lead to this conclusion: Blanchot did not have an iconoclastic idea about literature, but on the contrary, he considered what would be called a minimal image as the condition of possibility - "there is" - for the representative structure of image, for the very reason that he tried to resist such a structure. He thus came to recognize the passion of figuration in literature
Bizouard, Vincent. "Calculs de précision dans un modèle supersymétrique non minimal". Thesis, Université Grenoble Alpes (ComUE), 2015. http://www.theses.fr/2015GREAY075/document.
Texto completoAlthough the Standard Model has been very successful so far, it presents several limitations showing that it is only an effective low energy theory. For example, the neutrino masses or dark matter are not predicted in this model. Gravity is also not taken into account and we expect that it plays a quantum role at energies around the Planck mass. Moreover, radiative corrections to the Higgs boson mass suffer from quadratic divergences. All these problems underline the fact that new physics should appear, and this has to be described by an extension of the Standard Model. One well-motivated possibility is to add a new space-time symetry, called Supersymmetry, which link bosons and fermions. In its minimal extension, Supersymmetry can already solve the dark matter paradox with a natural candidate, the neutralino, and provide a cancellation of the dangerous quadratic corrections to the Higgs boson mass.In this thesis, we focussed on the Next-to-Minimal SuperSymmetric extension of the Standard Model, the NMSSM. To compare theoretical predictions with experiments, physical observables must be computed precisely. Since these calculations are long and complex, automatisation is desirable. This was done by developping SloopS, a program to compute one-loop decay width and cross-section at one-loop order in Supersymmetry. With this code, we first analysed the decay of the Higgs boson in a photon and a Z boson. This decay mode is induced at the quantum level and thus is an interesting probe of new physics. Its measurement has been started during Run 1 of the LHC and is continued now in Run 2. The possibility of deviation between the measured signal strength and the one predicted by the Standard Model motivates a careful theoretical analysis in beyond Standard Models which we realised within the NMSSM. Our goal was to compute radiative corrections for any process in this model. To cancel the ultraviolet divergences appearing in higher order computations, we had to carry out and implement the renormalisation of the NMSSM in SloopS. Finally, it was possible to use the renormalised model to compute radiatives corrections to masses and decay widths of Higgs bosons and supersymmetric particles in the NMSSM and to compare the results between different renormalisation schemes

Texto completoIn this thesis we are interested in the geometry of the space of cycles. We treat this problem by studying the invariant waist introduced by M. Gromov. We give a complete proof for the waist of the sphere theorem of M. Gromov. This proof is long and contains ideas coming from several branches of mathematics. We go further by generalizing this theorem for the unit spheres of the uniformly convex spaces. We give a lower bound for the waist of such spaces. Our result generalizes an isoperimetric inequality of M. Gromov and V. Milman. We study the topological/geometrical complexity of the space of cycles. Our particular interest is the space of 1-cycles embedded on the plane. We see 1-cycles as graphs and we search for the maximum number of vertices of minimal embedded graphs on the plane. We find the exact number for the case of 3-regular graphs and we give a conjecture for the general case

Texto completoThis thesis focuses on graphs, hypergraphs, and lattices. We study the complexity of the dualization of monotone Boolean functions, and its generalizations, through the many shapes it takes on these structures: minimal dominating sets enumeration, minimal transversals enumeration, lattice dualization, and meet-irreducible enumeration. Both tractable and intractable results are obtained, and future research directions are proposed. The thesis is organized as follows. A first part is devoted to the enumeration of minimal dominating sets in graphs. We obtain new output-polynomial time algorithms in graph classes related to Kt-free graphs and to posets of bounded dimension. A second part is devoted to generalizations of this problem in lattices. One generalization concerns the dualization in lattices given by implicational bases, the other deals with the enumeration of meet-irreducible elements. Both tractability and intractability results are obtained under various restrictions concerning width, acyclicity, and premises’ size in the implicational base. The two parts are sprinkled with hypergraph transversals enumeration and related notions

Texto completoThis thesis focuses on the stability of some minimal surfaces under the vanishing mean curvature flow in Minkowski space. This issue amounts to investigate a system which turns out to be hyperbolic as long as the involved surfaces are time-like surfaces.The work presented here includes two parts. The first part in joint work with Hajer Bahouri and Galina Perelman is dedicated to the issue of singularity formation in finite time for surfaces asymptotic to the Simons cone at infinity and the second part is devoted to the study of the stability of the helicoid.In the first part of this thesis, we prove by a constructive approach the existence of a family of surfaces which evolve by the vanishing mean curvature flow in Minkowski space and which as t tends to~0 blow up towards a surface which behaves like the Simons cone at infinity. This issue amounts to investigate the singularity formation for a second order quasilinear wave equation.The aim of the second part is to investigate the stability of the helicoid under normal radial perturbations. Actually, the helicoid is linearly unstable of index 1, and that is why we cannot expect to have stability for arbitrary perturbations. In this part, we establish that this instability is the only obstruction to the global nonlinear stability for the helicoid. More precisely, in the framework of normal radial perturbations, we prove the existence of a codimension one set of small initial data generating global solutions converging to the helicoid at infinity

Texto completoWith the development of advanced robotic systems and complex teleoperation tasks, the need to perform simulations before operating on physical systems becomes of increasing interest for feasibility tests, training of the human operators, motion planning, etc. Such simulations usually need to be performed with great accuracy of physical phenomena if, e.g., the operator is expected to face the same ones in the real world and in the virtual scene. Collision detection, i.e., the computation of contact points and contact normals between interacting rigid bodies, occupies a time-consuming part of such a physical simulation. The accuracy and smoothness of such contact information is of primary importance to produce a realistic behavior of the simulated objects. However, the quality of the computed contact information strongly depends on the geometric representation of the parts of the virtual scene directly involved in the mechanical simulation. On the one hand, discrete volumes-based and tessellation-based geometric representations allow very fast contacts generation at the cost of the potential introduction of numerical artifacts due to the approximation of the interacting geometrical shapes. On the other hand, the use of boundary representations (issued by CAD modelers) composed of smooth curve and surfaces removes this approximation problem but is currently considered being too slow in practice for real-time applications.This Ph.D focuses on developing a first complete collision detection framework on solids with smooth boundary representations that achieves real-time performances. Our goal is to allow the real-time simulation of industrial scenarios that require a high level of accuracy. Typical applications are insertion tasks with small mechanical clearances. The proposed approach is based on a bounding-volume hierarchy and takes advantage of key features of industrial mechanical components which are often modeled with surfaces describing functional contacts with canonical surfaces (cylinder, sphere, cone, plane, torus) while contacts over free-form surfaces like B-Splines are mostly accidental and encountered during operations of maintenance and manufacturing. We augment this hierarchy with the identification of supermaximal features in order to avoid redundant exact localization of contact points on canonical surfaces that may be represented as distinct features of the CAD model. In addition, we define polyhedral normal cones that offer tighter bounds of normals than existing normal cones of revolution. Moreover, we extend our method to handle configurations that involve beams modeled as deformable dilated Bézier curves. Finally, parallelization of the full approach allows industrial scenarios to be executed in real-time

Texto completoThe emergent active behaviors of molecular motors assemblies and cytoskeletal filaments systems remain poorly understood, though individual molecules have been extensively characterized. By controlling the geometry of actin polymerization with surface micropatterns of a nucleation promoting factor, we were able to demonstrate in vitro the emergence of flagellar-like beating of bundles of parallel actin filaments in the presence of myosin motors. We worked with both myosin V and heavy-meromyosin II. The waveform of oscillation was similar for the two types of motors, but oscillations with myosin II were one order of magnitude faster than with myosin Va. In both cases, a bending wave traveled at a uniform speed from the anchored base of the actin bundle towards the tip. As polymerization occurred, the actin bundle elongated at a constant speed, resulting in an increase of the oscillation period, but the speed of the traveling bending wave remains constant. GFP-tagged myosin V revealed the presence of a myosin concentration peak within the actin bundle. Strikingly, myosin V motors were locally recruited within the actin bundle, before a concentration wave propagated towards the bundle’s tip in concert with the actin bending wave. These results revealed a novel form of coupling between the myosin affinity for actin and the actin bundle shape. Our work demonstrates that active flagellar-like beating emerges as an intrinsic property of polar bundles of filaments in interaction with molecular motors. Structural control over the self-assembly process provides key information to clarify the underlying physical principles of flagellar-like beating

Texto completoWe associate to every compact polydisk B [belonging to ] Rn an algebra CB of real functions defined in a neighborhood of B. The collection of these algebras is supposed to be closed under several operations, such as composition and partial derivatives. Moreover, if the center of B is the origin, we assume that the algebra of germs at the origin of elements of CB is quasianalytic (it does not contain any flat germ). We define with these functions the collection of C-semianalytic and C-subanalytic sets according to the classical process in real analytic geometry. Our main result is an analogue of Tarski-Seidenberg's usual result for these sets. It says that the sub-C-subanalytic sets may be described by means of equalities and inequalities by terms obtained by composition of elements of the algebras CB, the functions x->^{1/n} and the function x->1/x. It is proved via a model theoretic preparation theorem

Texto completoCompartmentalization is of importance for our understanding of the emergence of life on earth but also for the development and design of minimal cells. Coacervation phenomenon allows spontaneous sequestration by molecular diffusion from aqueous medium but do not allow encapsulation of molecule inside. On the contrary, vesicular systems do not allow spontaneous encapsulation of molecules inside. Here we introduce a model built from saturated long chain fatty acids. This system can form both membranous vesicles and membrane free coacervated droplets that result from clouding by decreasing ph. We have shown that a large amount of proteins is encapsulated into vesicles after pre-crowding into coacervated. Encapsulation of enzyme in vesicles allow to increase the reaction rate compared to the reaction rate in diluted medium. Synthesis of proteins by cell-free system and metabolic reactions with proteins of mollicutes have not clearly been shown but they represent an essential element in the development of a minimal cell

Texto completoThe thesis focus on study geometric properties of definable sets in o-minimal structures and its applications. There are three main results presented in this thesis. The first is a geometric proof of the existence of Whitney (a) and (b)-regular stratifications of definable sets. The result was initially proved by T. L. Loi in 1994 by using another method. The second is a proof of existence of Lipschitz stratifications (in the sense of Mostowski) of definable sets in a polynomially bounded o-minimal structure. This is a generalization of Parusinski's 1994 result for subanalytic sets. The third result is about the continuity of of variations of integral geometry called local Lipschitz Killing curvatures which were introduced by A. Bernig and L. Broker in 2002. We prove that Lipschitz Killing curvatures are continuous along strata of Whiney stratifications of definable sets in a polynomially bounded o-minimal structure. Moreover, if the stratifications are (w)-regular the Lipspchitz Killing curvatures are locally Lipschitz

Texto completoIn absence of direct experimental evidence, it is essential to constrain the parameter space of the Minimal Supersymmetric Standard Model (MSSM) both at the Supersymmetry breaking and the electroweak scale. After a brief introduction to Supersymmetry (SUSY), we present an extensive analysis of electroweak, low energy, and cosmological constraints in minimal supergravity (mSUGRA) and gauge-mediated SUSY-breaking (GMSB) scenarios. We include the possibility of non-minimal flavour violation (NMFV) in the squark sector and define ``collider-friendly'' benchmark points based on detailed scans of the parameter space. We then consider neutralino pair annihilation into quark-antiquark pairs that dominates wide ranges of the mSUGRA parameter space. We present the corresponding full one-loop QCD and SUSY-QCD calculation and show numerically that the loop diagrams have an important impact on the annihilation cross section and, in consequence, in the prediction of the dark matter relic density, resulting in a modification of the preferred regions of the parameter space. We finally present analytical expressions and numerical predictions for squark, gaugino, and gravitino production cross sections at the LHC in GMSB with NMFV. We also discuss the phenomenology of flavour mixing and cosmological implications on the gravitino mass within this context

Texto completoAprès une brève introduction à la Supersymétrie (SUSY), nous présentons une analyse extensive des contraintes électrofaible, de basse énergie et cosmologiques dans des modèles de supergravité minimale (mSUGRA) et de brisure de Supersymétrie par médiation de jauge (GMSB). Nous incluons la possibilité de violation non-minimale de la saveur (NMFV) et définissons des scénarios ``benchmark'' basés sur des ``scans'' détaillés de l'espace des paramètres.
Ensuite, nous considérons l'annihilation d'une paire de neutralinos en une paire de quark-antiquark qui domine dans de larges régions de l'espace des paramètres dans les modèles mSUGRA. Nous présentons le calcul complet incluant des corrections à une boucle en QCD et SUSY-QCD de ces processus et montrons numériquement que les diagrammes à une boucle ont un impact non négligeable sur la section efficace d'annihilation. En conséquence, la prédiction de densité relique de matière noire reçoit des corrections importantes, ce qui résulte en une modification de la région cosmologiquement favorisée dans l'espace des paramètres.
Finalement, nous présentons des expressions analytiques et des prédictions numériques pour des sections efficaces de production de squarks, jauginos et gravitinos au LHC dans les modèles GMSB avec NMFV. Nous discutons également la phénoménologie du mélange de saveur et les implications cosmologiques sur la masse du gravitino dans ce contexte.

Texto completoOur processes are based on the fact that more and more children have difficulties with handwriting. Its aim is to propose a basis for thought on which a structured teaching of handwriting could lean. Our research focuses on Latin handwritten cursive small letters used in French schools. We made the assumption that this writing - a French school product - constitutes a system, the elements of which can be named and the functioning described. This hypothesis leads to the viewpoint that to take this system into account could be a help in the teaching of writing. Our choice is backed up by the results of neurosciences which show that to write with the hand would be a help in learning to read. From the analysis of comments on the legibility of a corpus of handwritings, we shall show how this system is built and what hierarchic and functional relations its elements continuously use with each other. We shall see that the heart of the system would be organized into two minimal units. Each of them set up as a basic form and two derivatives for the one, three for the other. The system constituted by these seven forms would allow all of the Latin cursive small letters used in France to be written. As an opening towards others projects, we submitted this system to the recognition of letters by children at nursery school. We noticed an improvement of the score between before and after a session of collective commented observation of the letters. This research about Latin handwritten cursive small letters brought us to make certain pedagogical proposals for the training of teachers

Texto completoThe purpose of this thesis is to better understand the confining strong interaction. To do so, we have investigated the results obtained with the use of the Wilson loop in Quantum Chromodynamics (aera law, Migdall-Makeenko equation,. . . ) and we have determined the relativistic interaction potential between the two constituents of a quarkonium, bound state of a quark and a antiquark, in the large color number limit and at large distance. Especially, we have shown that the evolution amplitude of a meson can be expressed as a fonctional expansion with respect to the Wilson loop. We have obtained two independent et compatible wave equations : in the Breit approximation, the dynamics is then described by a covariant three-dimensional Breit equation with only vector potentials which are expressed as functional derivatives of the minimal surface associated with the Wilson loop. We have then carried out a certain number of applications: We have determined the large distance contributions of the meson Hamiltonian in the non-relativistic limit. We have shown that the Breit equation reduces to a generalized Pauli-Schrödinger equation containing, in addition to a static confining potential, interaction terms that depend on the spins of the quark and of the antiquark and on the orbital angular momentum of the flux tube. Their structure appears to be in agreement with phenomenological data. We have verified in the equal masses case that the meson spectrum yields, in the high-energy regime, linear Regge trajectories whose the slope increases about 20 % when we take into account the flux tube

Texto completoLn the first part, we study 2-dimensional Almgren minimal canes in R4 , which is the first useful and necessary step to study Almgren minimal sets. We establish the Almgren minimality of the union of a pair of almost orthogonal planes in R4. The method is also generalized to prove the minimality of the almost orthogonal union of several planes or hyperplanes, as well as the almost orthogonal union of a plane and a Y in R5. Ln the second part, we introduce a definition of topological minimal sets, which is a generalization of that of Mumford-Shah-minimal sets. We prove some properties of topological minimal sets, and make a first step towards a characterisation of topological minimal sets. We restrict also the potential class of those Almgren minimal sets in R3 which are not cones

Texto completoDe plus, les recherches de production de scalaires neutres sont développées, dans les modèles généraux à deux doublets de Higgs de type II, au moyen d'une analyse dite "indépendante de saveur". On présente aussi les recherches concernant le boson de Higgs "invisible", où le boson Z se désintègre en une paire de fermions et le boson de Higgs en particules indétectables. L'utilisation de ces derniers résultats permet de contraindre les paramètres des modèles supersymétriques minimaux non-universels (sans unification de masse des jauginos).

Texto completoIn the framework of the nuclear power plants maintenance, the onsite workers incontrolled areas must performed some surface contamination controls of their tools, gloves, workingsuits and over their body parts which may be contaminated (neck and head for instance). However,surface beta contamination measurements can’t always been done as close as possible of the working location. The onsite ambient gamma background, being high and fluctuating, may disturb the radiation protection devices commonly used for surface contamination measurements.The main goal of this work was to conceive a radiation protection device adapted to the betasurface contamination of about a few Bq/cm2 (< 4Bq/cm2 typicaly) in a fluctuating (typicaly 30%variation per second) ambient gamma background of a few μSv/h (typicaly <100 μSv/h)

Texto completoThis thesis is about structural and algorithmic aspects of graphs. It is divided in two parts, which are about two different studies: one part is about centralized-sequential algorithms, and the other part is about distributed algorithms. In the first part of the thesis we study algorithmic applications of two graph structures called minimal separators and potential maximal cliques. These two objects are in the core of a meta-theorem due to Fomin, Todinca and Villanger (SIAM J. Comput. 2015), which states that a large family of graph optimization problems can be solved in polynomial time, when the input is restricted to the family of graphs with polynomially many minimal separators. The contribution of this part of the thesis is to extend the meta-theorem of Fomin et al. in two ways. On one hand, we adapt it to be valid into a larger family of problems. On the other hand, we extend it into a parameterized version, for several graph parameters. In the second part of this thesis we study the broadcast congested clique model. In this model, the nodes of a graph communicate in synchronous rounds, broadcasting a message of small size visible to every other node. The goal is to design protocols that recognize graph classes minimizing the number of rounds and the message sizes. The contribution of this part is to explore the role of randomness on this model, and provide protocols for the recognition and reconstruction of some graph classes
