Texto completoNeutrino physics is currently one of the most rich areas of high-energy physics, and neutrino oscillations in particular are opening the door to a new physics, beyond the standard model. In this context, the measurement of all mixing angles as non-zero offers the possibility of studying a possible violation of CP symmetry in the leptonic sector. The purpose of the T2K experiment, located in Japan, is to study these neutrino oscillations in the muon neutrino and anti-neutrino beam at J-PARC. The purpose of the T2K experiment, located in Japan, is to study these neutrino oscillations in the muon neutrino and anti-neutrino beam at J-PARC. Two channels thus studied: the disappearance of the muon (anti-) neutrinos of the beam and the appearance of (anti-) electronic neutrinos 295km further in the detector Super-Kamiokande. The measurement of the oscillation parameters involves a measurement of the number of events in the far detector, and requires a good modeling of the neutrino flux and interaction rate. These models are constrained before oscillation in a near detector, ND280, helping to greatly reduce the associated systematic uncertainties. T2K is the first experiment to show evidence of CP violation in the leptonic sector with a 2 sigma CL exclusion of CP conservation. In order to improve this constraint, a second phase of the experiment is proposed with an upgrade of the near detector in order to reduce the impact of systematic uncertainties on the cross section models

Texto completoThe PhD work is in the field of Neutrino Physics as a part of the T2K experiment. The thesis is divided into two subjects- detector characterization and preparation of physics analysis. In the context of the upgrade of T2K near detector- ND280, a model was developed and utilized to characterize the charge spreading in novel resistive Micromegas (ERAM) detector. In addition, pad-by-pad gain and energy resolution was obtained for each ERAM for a complete characterization. The results directly led to the selection of specific ERAMs for installation at specific positions in the High Angle-Time Projection Chamber anode planes for charge readout. In total, 37 ERAMs were successfully characterized using X-ray data from a test bench at CERN. This information was also used as inputs for reconstruction. Improvement in statistics and detection efficiency of charged-current quasi-elastic events in high Q² (4-momentum transfer) region after the ND280 upgrade was studied. The question of- how effectively the high Q² uncertainties will be constrained after the ND280 upgrade by the 4 high Q² parameters in the neutrino-nucleus cross-section model was addressed using T2K re-weighting tools and the ND280 fitter- GUNDAM. An important source of the high Q² uncertainties is the axial-vector form factor model (dipole) used currently in the cross-section model. Some alternative form factor models that can better constrain these uncertainties were also studied. The effect of uncertainties in nucleon removal energy estimation on different variables (muon kinematics, neutrino energy, etc.) was studied. Binned splines were produced for the 4 removal energy parameters in the cross-section model in the context of Oscillation Analysis using data collected in 2024

Texto completoThe development of a country depends primarily on the development of the life’s power of that country, managers, technicians, labors, who run the economy are the same ones who manage companies and institutions. How about Algeria? Will this Country be based one day on competences and not on oil revenues? This thesis has addressed this issue by studying the relationship between University and company and try to understand why in that country in full economic boom, companies complain about not having access to the skills they need while students newly graduates can not find work and are the most deprived group in terms of employment. The objective of this thesis is limited to study the reasons of such situation and try to find solutions to restore confidence between the University and the Company

Texto completo[This work takes place in the study of the central adenosine neurotransmitter system, improving a structure, the pineal gland, involved either in the physiology of reproduction in mammals or in the physiopathology of the central nervous system in human. It is known that adenosine and adenosine analogues regulate the neuronal activity in several brain areas and, thus, the synaptic transmission, and they have been shown to be highly active at the cellular level in altering neuronal activity and in affective behaviour as well. Specific, high affinity binding sites for adenosine have been identified in the central nervous system. It is assumed that most of the physiological actions of adenosine are mediated via the interaction of endogenous adenosine with these receptors. But nothing is known about them in the pineal gland. We have demonstrated the presence of A2 adenosine receptors in rat pineal membranes and we have shown that these receptors are coupled positive! y with the adenylate cyclase unit and thus increased in vivo and in vitro the synthesis and the release of melatonin, the major hormone of the pineal gland. This hormone is synthetized after stimulation by adenosine and specific A2 adenosine agonists. Nor-adrénaline, an alpha 1 and beta-adrenergic agonist potentiates their activation. This result suggests an interaction between the transduction mecanisms implying the adenylate cyclase and the -phosphoinositides systems. We have confirmed the presence of A2 receptors in the healthy human pineal gland and we have observed a modification of the binding parameters in the pineal glands of victim suicides. At last, we have observed that physiological and environmental parameters such as aging, methylation processes, continuous light, modulate the adenosinergic neurotransmission in the brain and the pineal gland. ]

Texto completoThe goal of computational linguistics is to provide a formal account linguistical knowledge, and to produce algorithmic tools for natural languageprocessing. Often, this is done in a so-called generative framework, where grammars describe sets of valid sentences by iteratively applying some set of rewrite rules. Another approach, based on model theory, describes instead grammaticality as a set of well-formedness logical constraints, relying on deep links between logic and automata in order to produce efficient parsers. This thesis favors the latter approach. Making use of several existing results in theoretical computer science, we propose a tool for linguistical description that is both expressive and designed to facilitate grammar engineering. It first tackles the abstract structure of sentences, providing a logical language based on lexical properties of words in order to concisely describe the set of grammaticaly valid sentences. It then draws the link between these abstract structures and their representations (both in syntax and semantics), through the use of linearization rules that rely on logic and lambda-calculus. Then in order to validate this proposal, we use it to model various linguistic phenomenas, ending with a specific focus on languages that include free word order phenomenas (that is, sentences which allow the free reordering of some of their words or syntagmas while keeping their meaning), and on their algorithmic complexity

Texto completoThe principal aim of our thesis is to assess the impact of national program of upgrading on the competitiveness of Algerian Enterprises which have adopted and finalized this kind of program. To do this, we have applied two approaches in order to evaluate the impact of the upgrading; it is the univariate and multivariate approach. In the first approach, we have utilized three methods, namely: parametric test of Student and the nonparametric test of Wilcoxon, in addition a simple regression model. While the second approach apply a multiple regression model. Besides, the empirical analysis involves panel data of a sample of 67 Algerian enterprises observed during the period 1997 to 2008. Our thesis is composed of four chapters. The first chapter aims to introduce the theoretical sub-foundation useful for understanding the competitiveness while the upgrade strategies are stated in the second chapter. The third chapter presents upgrading strategies adopted in Algeria, and finally the last and fourth chapter presents the methodology and the results of the empirical evaluation of the upgrade program of the competitiveness of Algerian Enterprises

Texto completoGraphic cards (GPUs), initially used for graphic processing, have a highly parallel architecture. Innovations in both architecture and programming languages opened the new domain of GPGPU where GPUs are used as accelerators for general purpose HPC applications.Our main objective is to facilitate the use of these new architectures for high-performance computing needs; our research follows two main directions.The first direction concerns an automatic code transformation from a high level code into an equivalent low level one, capable of running on accelerators. To this end we implemented a code transformer that can handle parallel “for” loops (single or nested) of an OpenMP code and convert it into an equivalent CUDA code, which is in a human readable form that allows for further optimizations.Moreover, the future of HPC lies in distributed architectures based on hybrid nodes. Specific programming schemes have to be used in order to allow users to benefit from such multiGPU nodes. We conducted a comparative study which revealed that using OpenMP threads is the most adequate way to control multiple graphic cards as well as manage communications efficiently within a multiGPU node

Texto completoSuperoxide reductase is a newly discovered enzymatic activity, that catalyzes the reduction of O2o- to H2O2 exclusively. There are three classes of SOR. The active site of SOR consists of a non-heme Fe2+ center in an unusual [His4 Cys1] pentacoordination. Upon oxidation, a conserved glutamate residue becomes the sixth Fe3+ ligand. Our resonance Raman spectroscopic studies on representative SOR proteins active sites from each class revealed structural variations. During our work, we have characterized a meta-stable non-protonated Fe3+-h2-O2 species after reaction with excess H2O2. Mutation of the glutamate residue to alanine resulted in the stabilization of the Fe3+-h2-O2 species. This indicated that this glutamate side chain facilitates H2O2 release. We have also identified a Fe3+-OH species which is responsible for observed pH-dependent spectroscopy changes of the SOR active site. The HO- species comes from the water solvent, which could be the second proton donor required for the H2O2 release

Texto completoThe work described in this manuscript deals with the synthesis, the enzymatic degradation and the physicalchemistry characterization of new excipients based on a natural polysaccharide, dextran. These excipients can serve coating or agent matrix for the realization of oral pharmaceutical forms at colon-specifie release of the active ingredients. To this end, two main strategies for syntheses were performed on dextran to make it hydrophobie. The first is based on the esterification of hydroxyl groups of dextran to prepare three families of dextran esters (acetate, propionate and butyrate) with three Degree of substitution (1 , 2 and 3). The second strategy allows to obtain three types of dextran block copolymers (di, tri and tetra-block copolymers) by freeradical emulsion polymerization of one or more acrylic monomers (MA, MMA and MAA) on the block of dextrans. The beneficial results of in vitro release of theophyllin from tablets coated individually with different types of dextran block copolymers were allowed to determine the potential uses of dextran block copolymers to deliver oral dosage forms in the colon

Texto completoThe software packages of the urban storm water drainage system use different models for representation of the network hydraulic operation. These models are based on either the simple concepts of the flood wave transferring or the relations of the fluid mechanics which solve the Saint Venant equations. Considering advantages and disadvantages of every model, it seems helpful to develop the methodological concepts which permit the model designer as well as the software user to assess every model of the network simulation. The aim of this study is to introduce the general elements of comparison which allow the assessment of the performance level of a model and to define its application field. This research has directed on one band to model results comparison and on the ether band to study of the model capacity in global representation of the networks hydraulically behaviour. The main results of this research are : - Development of one model evaluation and comparison method, and putting it into practice ; - Examination of the behaviours of Saint Venant an Muskingum models of CEDRE software package; - Introduction of necessary elements which will be used in the realisation of an automatic model choosing tool. This tool will be installed in future urban drainage packages. - Supplying of necessary steps for development of the numerical results which, without any difficulty, could be considered as "correct" for set of model designers. ]

Texto completoThe installation of new resistive plate chamber detectors (RPCs) in the 2 most remote sectors (RE3 / 1 and RE4 / 1) of the CMS End-Caps is planned during the Phase-2 CMS upgrade in 2024. Glass Resistive Plate Chambers (GRPC) with low resistivity glass as electrodes have been proposed to equip these sectors. These detectors should sustain these zones' particle rate. The aim of this Thesis is to study and characterise these detectors, their associated readout electronics and their behaviour under radiations.Two ways of building half size chambers by tesselation of glass plates with maximal size 32*30cm² have been developped. A new PCB with strips readout read by dedicated ASICs (PETIROC2A) without eta segmentation is also described. It allows, thanks to a 25 ns time-resolution TDC to estimate the particle crossing position on the strip with a resolution of the order of cm. This manuscript describes all these devices and discusses the devices' performance measured in beam tests done at the CERN PS and SPS accelerator and at the Gamma Irradiation Facility (GIF++). This study shows that the low resistivity glass, though able to sustain the particule rate, is not the best option for the CMS upgrade. On the contrary, the tested electronic has been proven to fit the CMS upgrade requirements and is now considered as the baseline of the CMS End-Caps RPC upgrade project

Texto completoStorytelling has been growing in popularity in many fields such as marketing, politics and science which brought us to question the relevance of this technique in writing. We chose a population of high-level autistic people or Asperger's because they have a different understanding than people without autism and only a few texts are adapted to their needs. From this perspective, we propose to understand the influence of storytelling on the reading comprehension of high-level autistic people or Asperger's on two professional texts addressing the same subject but possessing different dominant structures. To understand this influence, we relied on the relevance theory of Sperber and Wilson (1989), in particular by using "cognitive effects" and "processing efforts" concepts to measure relevance. We recruited ten participants and divided them into two groups: a group to read and annotate the informative text and a group to read and annotate the narrative text. We used three data collection techniques: the questionnaire, the plus-minus method and the semi-structured interview. Research results show that storytelling has a real influence on reading comprehension of high-level autistic people or Asperger's but that influence is not homogeneous: it has several degrees of relevance, ranging from relevant to irrelevant. Depending on many aspects, storytelling is relevant for one participant, but not for another. The writer should therefore always strive to adapt his text to the background of his reader to optimize relevance.

Texto completoThe automotive industry is required to accelerate the development and deployment of electrified vehicles at a faster pace than ever, to align the transportation sector with the climate goals. Reducing the development time of electric vehicles becomes an urgent priority. On the other hand, the industry is challenged by the increasing complexity and large design space of the emerging electrified powertrains. The existing approaches to address component design, such as numerical methods exemplified by finite element method, computational fluid dynamic, etc., are based on a detailed design process. This leads to a long computational burden when trying to incorporate them at system-level. Speeding up the early development phases of electrified vehicles necessitates new methodologies and tools, supporting the exploration of the system-level design space. These methodologies should allow for assessing different sizing choices of electrified powertrains in the early development phases, both efficiently in terms of computational time and with reliable results in terms of energy consumption at system-level. To address this challenge, this Ph.D. thesis aims to develop a scaling methodology for electric axles, allowing system-level investigation of different power-rated electric vehicles. The electric axle considered in this thesis comprises a voltage source inverter, an electric machine, a gearbox, and a control unit. The scaling procedure is aimed at predicting the data of a newly defined design of a given component with different specifications based on a reference design, without redoing time and effort-consuming steps. For this purpose, different derivations of scaling laws of the electric axle components are thoroughly discussed and compared at component-level in terms of power loss scaling. A particular emphasis is placed on examining the linear losses-to-power scaling method, which is widely employed in system-level studies. This is because, this method presents questionable assumptions, and has not been the subject of a comprehensive examination. A key contribution of the presented work is the derivation of power loss scaling laws of gearboxes, which has been identified as a gap in the current literature. This is achieved through an intensive experimental campaign using commercial gearboxes. To incorporate the scaling laws at system-level and study the interaction between the scaled components, the energetic macroscopic representation formalism is employed. The novelty of the proposed method lies in structuring a scalable model and control for a reference electric axle to be used in system-level simulation. The novel organization consists of a reference model and control complemented by two power adaptation elements at the electrical and mechanical sides. These latter elements consider the scaling effects, including the power losses. The methodology is applied for different study cases of battery electric vehicles, ranging from light to heavy-duty vehicles. Particular attention is paid to assessing the impact of the linear power-to-losses scaling method on the energy consumption considering different power scaling factors and driving cycles, as compared to high-fidelity scaling methods

Texto completoUnderstanding the development of numerical abilities is a major issue to guide educative and reeducative practices in mathematics in young children. National and international investigations has demonstrated that the mathematical skills of students has decrease since 2003 (PISA, 2012). Nowadays, weak capacities to map numerical representations and therefore a defective « number sense » (Dehaene, 1997 ; 2001) is the most supported hypothesis. The « number sense » is contained into the analogical and non-verbal representation of number. In this work, we consider that numerical estimation is a good way to exercise this mapping and give sense to verbal and written numerical symbols. Indeed, the role of numerical estimation needs to be specified in order to lead the (re)educative practices (Dehaene, 1997 ; 2001 ; Von Aster et Shalev). During three experimental studies, we explore the role of numerical estimation, in an educative and reeducative way in children in first year and children with down’s syndrom. The acquisition of numerical representations and the complex relations they have are also explored and discussed through a spirality hypothesis in order to better specify actual models of number treatment

Texto completoThis study focuses on the implementation of a mindfulness training program for 15 young elite golfers, aged 17 to 20, from a Quebec-City golf academy. The program spanned over 6 weeks, and included formal and daily meditative practice of approximately 10 minutes with audio support and weekly monitoring of participant progress. The objectives were to assess whether this program increased mindfulness in everyday life and in golf, and to check whether this increase persisted over time. A single-subject A-B multiple-baseline design was used. Golfers were assessed with the French computerized versions of the Mindful Attention Awareness Scale (MAAS) and Mindfulness Inventory for Sport-Golf (MIS-Golf). After establishing a baseline, the assessments were carried out on a weekly basis during the intervention and follow-up phases. The tendency to be mindful in daily life was measured, as well as the 3 dimensions of mindfulness in the specific context of golf: awareness, acceptance and refocusing. Visual inspection of the graphs and four series of mixed-model regression analyses were performed. The results revealed (significant) partial low to moderate evidence supporting the effectiveness of the program regarding mindfulness in everyday life, as well as the "acceptance" dimension of mindfulness in golf. This mindfulness training program is considered to be viable, and its initial results are promising. Future research should optimize some of its qualities and refine the study of the effects of the program.

Texto completoThe spatial distribution of Cd was studied and its toxicological impact was evaluated using metallothionein (MT), malonedialdehyde (MDA) and acetylcholinesterase (AChE) as biomarkers. Results showed that Cd contamination migrates southward the polluted site by the NS currents. The biomarkers concentrations reflect the alarming state of this ecosystem. The clam Ruditapes decussatus and the cockle Cerastoderma glaucum may have settled up sorne peculiar adaptive strategies to survive in such conditions. Two partial MT cDNAs were cloned from R. Decussatus and C. Glaucum and used as probes to quantify the MT mRNA levels. Dot blot analysis confirmed the induction of MT gene expression in gills of the contaminated animaIs. A genetic discrimination between different populations of C. Glaucum from the Mediterranean sea, Atlantic and the North sea, and C. Edule from Atlantic and the North sea were performed using the 28S, ITSI and COI sequences

Texto completoThe research aims at the determination of the factors which account for the perception of the firm’s competitiveness at the Euro-international level, and at seeing whether the up-grading strategy allows the industrial firm to become competitive. In a first part, entitled “The competitiveness process : a multidimensional analysis”, we have tried to show theoretically and then empirically that the concept of competitiveness can be bound to the firm and/or to the product, both at the national and international levels. The theoretical syntheses, were they economic or organisational, have shown a multidimensional and multifactor aspect to competitiveness. In the second part, entitled “up-grading strategy : a new development orientation for the Tunisian small and middle industries (PMI)”, we try to see whether the up-grading strategy in order to reach the competitiveness goal, follows a strategic process which allows the sustained development of the firm. We have built all our reasoning around the indications of the basic theoretical models. We have integrate within each part (I and II) the empirical validation of each hypothesis of the model that we have devised in order to explain competitiveness and the up-grading strategy according to an approach based on the perception of the Tunisian leaders. The proposed survey concerned seventy-six small and middle Tunisian industrial firms. According to the Tunisian officials, competitiveness was appreciated through the competitiveness of the nation, of the firm and of the product and the efficiency of “up-grading” national programme was conditioned by the success of the carrying out of the whole up-grading procedure
