Full textThe technique MC-CDMA (Multi-Carrier Code Division Multiple Access) that combines Multicarrier modulation and spread spectrum is a very promising for downlink of future communication systems with very high debit rate. However, over different subcarrier, each chip of spreading code is transmitted, the codes orthogonallity can not be maintained in a frequency selective channel and the MAI (Multiple Access Interface) limits the system preformance. The goal of this thesis is to study an optimisation of MC-CDMA system in a multi-path based on the development of an original code allocation strategy. It is based primarly on a study of the performance of an MC-CDMA system. After obtaining the analytical expressions of the correlation channel after equalization and MAI power, the system performance is analyzed in terms of degree of fading corralation on sub-carrier, the considered technique of equalization (MRC, EGC, MMSE) and the properties of spreading codes assigned to active users. To optimize the MC-CDMA technology, our approach consists in selecting the sets of codes "optimal" that minimizes the MAI power affecting different active users. The exhaustive search of these codes is more complex in term of computing time when the code length increases, we propose a simple and speed code allocation strategy to minimize cost function related to the MAI and obtained by the approximation of channel correlation. Finally, we present an iterative algorithm designed to have a low complexity, and to limit the number of considered ocdes sets integrating a new users easily and independent of the concerned codes family. The simulation results illustrate the effectiveness of our algorithm based on the degree of subcarriers corraltion, the rate of loading and signal to noise. Unlike to conventional optimization techniques, our solution significantly improves the performance of MC-CDMA system without introducing additional complexity at the receiver

Full textThe use of aerodynamic coefficients for the characterization of the behaviour of an object in flight remains one of the oldest and most emergent research project in the field of exterior ballistic. The present study investigates the identification of the aerodynamic coefficients based on measured data, gathered during free flight tests from different measurement techniques. This project deals with topics as modelling, defining and mastering parameter identification techniques best suited to the problem of the aerodynamic coefficients determination. In the frame of this study, an identification procedure was developed for the aerodynamic coefficients determination based on free flight measurements and was tested for two application cases: a re-entry space vehicle and a fin stabilized reference projectile. This procedure requires several steps such as the description of the behaviour of the vehicle in free flight as a nonlinear state-space model representation, the polynomial descriptions of the aerodynamic coefficients as function of Mach number and incidence, the a priori and a posteriori identifiability analyses, followed by the estimation of the parameters from free flight measurements. Moreover, to increase the probability that the coefficients define the vehicle’s aerodynamics over the entire range of test conditions and to improve the accuracy of the estimated coefficients, a multiple fit strategy was considered. This approach provides a common set of aerodynamic coefficients that are determined from multiple data series simultaneously analyzed, and gives a more complete spectrum of the vehicle’s motion
Norheim-Hansen, Anne. "Sustainable development and strategic alliances : four essays on implications of firms' environmental performance for their cooperative strategies." Thesis, Aix-Marseille, 2014. http://www.theses.fr/2014AIXM1035.
Full textStrategic alliances have become as much a necessity as a choice for companies to be competitive in today's markets. However, making strategic alliances work is not evident. Failure rates between 30% and as high as 70% have been regularly reported. A substantial stream of research has examined how these numbers can be improved. Partner selection has been identified as a key success factor. In fact, partner-specific attributes, affecting which partners are selected, tend to have snowball effects beyond the formation phase to the design and postformation phases. Building on previous studies investigating the attribute of reputation, this thesis fills a gap by exploring the role reputation for environmental performance can play in determining firm-specific and joint competitive advantages in the different phases of strategic alliances. In four individual but connected Essays, specific research questions are theoretically examined under the Natural-Resource-Based View (NRBV) and Strategic Cognition Perspective. The study's hypotheses are empirically tested using data collected from CEOs and top managers in 176 Norwegian manufacturing firms

Full textThis thesis deals with the emotional regulation of foster children and adolescents placed to the “Aide Sociale à l’Enfance”. We approach the subject through the prism of developmental psychopathology, related to the theory of attachment. The coping strategies and temperament are studied as emotional regulators. The issue is to study the effects of maltreatment and of the placement trajectory in order to highlight the resources and vulnerabilities of these young people. This thesis develops a quantitative approach based on two series of questionnaires carried out on maltreated youth and from a control sample. The results shed light on the risk and protective factors generated by such life and highlight the specific needs of these young people. A number of recommendations are made to invite child protection institutions to propose other means of support, with the goal of promoting tailor-made care, adapted to the characteristics of the foster children and adolescents

Full textOriginally introduced by Katzenellenbogen in 1981 , self-immolative spacers are defined as covalent assemblies that are able to correlate cleavage of two chemical bonds. First, the protecting group is cleaved, generating an intermediary which spontaneously leads to the rupture of the bond between the spacer and the released molecule (bioactive compound for instance). Katzenellenbogen planned that self-immolative spacers could allow to overcome limitations of classic therapies (especially direct administration of drugs) and constitute a novel and efficient alternative to actual prodrug strategies. Effectively, spacers have opened many possibilities in this field, but also in other domains (like analytical chemistry, material sciences, …) which will be presented in this manuscript.We also took care to detail self-immolation mechanisms (the step leading to the release of the leaving group from the intermediary): indeed, the mechanism is the most important factor of the spacer, determining its properties (kinetic of the process, chemical links allowed). Therefore, it is crucial to determine advantages and drawbacks of each mechanism in order to permit a rational choice of the spacer depending on the application we choose.Our work consisted to complete known kinetic data, leading us to acquire an overview of existing spacers.Self-immolative spacers have been introduced to overcome limits of actual strategies, but they are not always able to answer particular problems (sensitivity and selectivity of their triggering events principally): this leads us to propose a new generation of spacers capable of resolving these problematics.Our researches permitted us to compare kinetic of cyclizing spacers and to confirm that elimination based spacers show a larger scope for potential uses.Starting from this, we developed two series of derivatives using this mechanism: - Bi-triggered anilines: releasing the leaving group after two specific stimuli (only one for reported spacers actually). We are convinced that this new class of spacers can constitute a real innovation for selective treatments. - Three-branched phenol: able to release the compound by three different ways of elimination. This property can increase drastically the sensitivity of the spacer for its activation pathway, considering triggers are three-time more numerous. Even if the compound has not been obtained, significant results in its synthesis have been observed: these results on this interesting project leading us to propose new synthetic strategies in order to obtain this ultra-sensitive compound

Full textMultiple sclerosis (MS) is a chronic inflammatory autoimmune disease affecting the central myelin. Progress has been made for MS treatment, but effective neuroprotective drugs against MS-evoked axonal damages and severe disability are still missing. This thesis assessed the potential of XBD173, a ligand of the translocator protein controlling neurosteroidogenesis and neuroinflammation, to improve symptoms in the proteolipid protein-induced MS model (EAE-PLP mice) that mimics the relapsing-remitting form affecting 85% of MS patients. Our results show that XBD173 at low dose decreases serum levels of pro-inflammatory interleukins, prevents the repression of myelin and axonal markers, and also ameliorates clinical deficits in EAE-PLP mice. The beneficial effect of XBD173 against clinical symptoms was also observed in the EAE-MOG mice mimicking the progressive MS. Promising perspectives are open for the development of effective strategies against MS with little or no serious side effects

Full textFor future wireless communication networks one of the major concerns for service providers is to provide seamless connectivity to the end-users with quality of service (QoS) as high as possible. However, to achieve the determined QoSs for all users in the network is a challenging issue due to the time-varying characteristics of communication channels, caused by multi-path fading, path-loss and shadowing, and interference as a result of sharing the same time-frequency system resources with the other communicating terminals. Recently, base station (BS) cooperation and relay station (RS) deployment have been proposed as promising technologies to notably improve the performance of next-generation wireless systems in terms of fairness, coverage, energy/cost and spectral efficiency. In this thesis, we gravitate our attention towards the use of relay stations in different wireless communication systems such as cellular telephony, Ad-hoc and satellite networks with reliability and achievable rates being our main figures of merit. In particular, we project the insights gained from information theoretic analysis of various relaying strategies into the real world settings, and assess the effectiveness and potentials of relaying in various wireless applications

Full textThis work focus on video transmission over mobile a hoc net-works. Several schemes have been proposed in order to improve and guarantee a high quality of service of applications integrating video transmission over ad hoc networks. The performance of these schemes is assessed by using network simulator tools such as NS-2 and GLOMOSIM. However, the physical layer usually used in network simulators does not properly model the propagation phenomenon as in a real urban environment. We have proposed a realistic physical layer which considers all specificities of mobile wireless channel. This physical layer uses a ray tracer propagation mo-del and allows assessing a SISO and MIMO wireless links following the IEEE 802. 11a and IEEE 802. 11n standards, respectively. This work clearly shows that we should consider a realistic physical layer in network simulator to assess the performance of video transmission schemes. On the other hand, we have pro-posed an original joint source-channel coding solution for a hierarchical trans-mission of scalable video coder, known as H. 264/SVC. This solution exploits a spatial diversity of a MIMO channel jointly with a hierarchy provided by the H. 264/SVC coder in order to guarantee the best quality of the received video regardless the channel conditions. The proposed solution uses a precoder designs for an optimal power allocation toward transmitted antennae in order to minimize the received video distortion
