Texto completoThis thesis presents the results of the analysis of the experiment "Dibaryon" (PS159), performed at CERN. This experiment studies the strange dibaryonic systems in the reactions K- + d →K+ + X-, K- + d →π- + X+ et π+ + d → K+ + X+ between. 9 and 1. 4 GeV/c. A dibaryon, with strangeness -2, is searched for in the reaction K- + d → K+ + X-. An upper limit for the production cross section of such a state is established in the range 5 to 40 nb/sr, for a dibaryon mass between 2100 to 2500 MeV/c2. A signal in the mass spectrum of the x+ system, at 2129 MeV/c2, already indicated in the reaction K- + d →π- + X+, is observed in the reaction π+ + d →K + X+. A study of this signal is performed in these two channels at different energies. The triangular diagram model, with an intermediary sigma exchanged, is in good agreement with the variation of the production cross section in the two channels and as a function of the energy

Texto completoIn natural ecosystems, bacteria have a remarkable tendency to adhere to surfaces within microbial consortia called biofilms. In order to prevent colonization of surfaces, it is necessary to know bacterial mechanisms involved in biofilm formation. The aims of this work were to identify and to classify regulatory mechanisms that control synthesis of curli, a structure of attachment, according to medium osmolarity and integrity of bacterial membrane. We discovered that the two-component systems EnvZ/OmpR, CpxA/CpxR and RcsC/RcsB play a fundamental role in the transcriptional control of curli genes with complexes balances between activators and repressors. Analysis of the expression, both in time and space, of the curli genes in biofilm also shows that curli are essential in each different stage of biofilm development process

Texto completoGiven a one dimensional substitution σ, one can define the continuous hull Ωσ for the R-action given by translations and so we obtain a dynamical system Ωσ,σ. If the substitution we choose is primitive, then we can construct an hyperbolic tiling on Poincaré's half-plane equiped with its standard metric \frac{\mathrm d x +\mathrm d y}{y^2}. By analogy of the standard case, we can define two continuous hulls, denoted X_P ^ N and X_{P(c)}^G, where P(c) is a colored tiling (in such fashion that the action of G is free), and the groups are denoted respectively N= \{ \mathbb{H}_2 \to \mathbb{H}_2, z \mapsto z +t, t\in \R\} and G = \{ \mathbb{H}_2 \to \mathbb{H}_2, z \mapsto a z +b,(a,b) \in \R_+ ^* \times \R\}.\par Using Jean Renault's construction of the reduced C^*-algebra of a groupoid , the results of Ian Putnam and Jared Anderson and the Morita equivalence between C((\Xi\times \R)/\As) and C(\Xi) \rtimes \Z, we describe the C^*-algebra of the hyperbolic tiling using generators and relations. Finally we obtain for the Fibonacci, Thue-Morse and Tribonacci substitutions the full description of the generators of K_* (C(X_{P(c)}^G ) \rtimes G)

Texto completoGiven a one dimensional substitution $\sigma$, one can define the continuous hull $\Omega_\sigma$ for the $\R$-action given by translations and so we obtain a dynamical system $(\Omega_\sigma,\sigma)$. If the substitution we choose is primitive, then we can construct an hyperbolic tiling on Poincaré's half-plane equiped with its standard metric $\frac{\mathrm d x +\mathrm d y}{y^2}$. By analogy of the standard case, we can define two continuous hulls, denoted $X_P ^ N $ and $X_{P(c)}^G$, where $P(c)$ is a colored tiling (in such fashion that the action of $G$ is free), and the groups are denoted respectively $N= \{ \mathbb{H}_2 \to \mathbb{H}_2, z \mapsto z +t, t\in \R\}$ and $G = \{ \mathbb{H}_2 \to \mathbb{H}_2, z \mapsto a z +b,(a,b) \in \R_+ ^* \times \R\}$.\par Using Jean Renault's construction of the reduced $C^*$-algebra of a groupoid , the results of Ian Putnam and Jared Anderson and the Morita equivalence between $C((\Xi\times \R)/\As)$ and $C(\Xi) \rtimes \Z$, we describe the $C^*$-algebra of the hyperbolic tiling using generators and relations. Finally we obtain for the Fibonacci, Thue-Morse and Tribonacci substitutions the full description of the generators of $K_* (C(X_{P(c)}^G ) \rtimes G)$

Texto completoWe define and study a combinatorial optimization problem and mixed-integer linear programming, that models multi-path routing in a Network-on-Chip with guaranteed traffic. Based on time division multiplexing, the model allows to avoid collisions, deadlocks and livelocks in irregular network topologies, while minimizing latency. An extension of this multi-path problem is also presented that allows dynamic reconfigurable routing at execution time. In that case, independent sets of valid routes are pre-computed in such a way they can be interchanged during execution with no impact on the existing traffic, while reusing all the vacant and free time-slot resources. A time-expanded graph approach is retained for the solution process. First, we present a set of basic operators to compute shortest paths. They can be a greedy parallel construction heuristic, neighborhood operators, and a modified Dijkstra algorithm in a time expanded graph that allows computing a single path in an occupied Noc in pseudo-polynomial time. Then, to solve all the problems, operators are introduced and combined within three iterated local search methods that can quickly generate feasible solutions, an evolutionary algorithm based on population conferring diversity solutions in search of solutions and a memetic algorithm, taking advantage of the benefits of the previous two. Experiments are done on a set of benchmarks representative of real life applications, and instances of artificial applications randomly generated from real cases, to illustrate the performance and robustness of research methods

Texto completoVibrational spectroscopy field is still quite active nowadays: actually, its quickness of acquisition and its ability to identify functional groups make it a perfectly suitable device for characterisation of very reactive and/or short-life compounds. A spectrum analysis becomes very complex with the growth of studied systems’ size and presence of parasite molecules. Thus, recent methodological breakthroughs couple together with improvements in the computing area enable from now on an accurate theoretical assessment for systems up to 4-5 atoms, but the chemist is quickly limited in his investigations when larger molecules are considered. The aim of this thesis is to provide a computing tool designed to process a direct variational algorithm, which is the only one able to treat explicitly phenomena such as resonances, on chemical systems up to 20 atoms. In order to reach this goal, a parallel coding approach has been considered. This software, called P_Anhar, has then been used to perform a complete vibrational study on a chemical family, namely the methylalkali. From a spectroscopic point of view, there is a strong discrepancy between theoretical and experimental works dealing with these systems. Using P_Anhar has brought some parts of an answer to this discrepancy, and an interpretation of reference experimental spectra is consequently proposed, in order to revisit them

Texto completoThis thesis work is part of the process of continuous improvement of the efficiency and linearity of power amplifiers in presence of signals on modulated carriers used in modern telecommunications systems. These signals have a high PAPR and a statistical envelope distribution centered below the envelope peak value. As a result, conventional power amplifiers (Class AB fixed bias) are often oversized to meet the needs of the telecom industry. The envelope tracking technique has been used to increase the PAE along the OBO (10 dB for LTE) while maintaining a constant power gain associated to a good linearity in terms of AM/AM conversion. A power amplifier design method in MMIC technology based on the use of GaN HEMTs has been developed and is used to design an APdelivering an output power of 4W and operating in K-band [17-20GHz]. The realized APwas then coupled to a digital drain bias modulator. The APand bias modulator assembly constituting an envelope tracking system called APSE was characterized in terms of efficiency and linearity in presence of modulated signals. The APSE shows very interesting performances compared to those obtained with a fixed bias AP. Indeed, at an OBO of about 7dB, in the [17-20GHz] band, the PAE is improved by [10-7.5]. The average PAE along the OBO varies between 32 and 36% over the considered band and it is associated to an EVM varying between 5 and 1.6% with a quasi-static DPD applied to the baseband signal.The characterizations of APSE have demonstrated the interest of the use of envelope tracking power amplifiers in modern telecommunications systems
