Der volle Inhalt der QuelleThe explosion of multimedia applications is largely due to the efficiency of the compression techniques used. H. 264/AVC, also known as MPEG-4 Part 10 is the newest video coding standard. It is more effective than previous standards (MPEG1, MPEG2, part 4, H26x…) and achieves significant compression gains. As for other standards, the rate control is a key element of H. 264/AVC because it helps to regulate the visual quality of the reconstructed sequence while respecting the bandwidth constraints imposed by the channel transmission. In accordance with the specified target bit-rate, the rate control algorithm determines appropriately the quantization parameters. Basically, a first Rate-Quantization function elaborates a relationship between the rate and the quantization parameter (QP). A second function called Distortion-Quantization estimates the distortion (or quality) of the reconstructed video based on the used quantization parameter. These two functions lead together to a relationship (usually quadratic) between the quantization parameter, the target number of bits and the basic unit (Frame, Slice, macroblock or set of macroblocks) statistics. These functions have been the subject of several studies. The models that have been adopted and therefore recommended by the group standardization, do not generally offer better performances and they are far from optimal. This thesis is in this context. Its main objective is to develop and design new techniques to improve the performance of the rate control algorithm and those of the H. 264/AVC standard. These techniques are based on both a detailed analysis of the major current limitations and a wide literature review. Our purpose is to provide a more appropriate determination of the quantization parameter, a selective bit allocation that integrates Human Visual System properties and enhances the reconstructed video quality. To determine accurately the quantization parameter, two Rate-Quantization models (R-Q) have been proposed. The first model designed for Intra-Frames, is a non-linear one. It is used to determine the optimal initial quantization parameter, while exploiting the relationship between the target bit-rate and the complexity of Intra-Frames. The second model is a logarithmic one and it is designed for Inter coding units. It replaces the two models used by the H. 264/AVC rate controller and reduces the computational complexity. The frame layer bit allocation of the H. 264/AVC baseline profile remains basic. It assumes that GOPs (Groups Of Pictures) have similar characteristics and the target number of bits are fairly allocated to coding units regardless of their complexity. For a more accurate bit allocation, a new model has been proposed including two complexity measures. The first is a motion ratio determined from the actual bits used to encode the previous frames. The second measure uses the difference between adjacent frames and the histogram of this difference. Finally, to better control the visual quality of the reconstructed video, a saliency map is included into the bit allocation process. The saliency map generated by a bottom-up approach, simulates the human visual attention. It has been used to adjust the quantization parameter at frame layer. This adjustment allows the assignment of more bits to frames containing more salient regions (supposed to be more important than others). At macroblock layer, the saliency map is exploited to efficiently allocate the number of bits among the macroblocks of the same frame. This bit repartition by ''region'' of interest improves the visual quality of the frame. Experimental simulations show that the proposed models, when compared with two recent algorithms of rate control (JVT-O016 and JM15. 0), improve significantly the coding performances in terms of average bit-rates and PSNR. More consistent quality and therefore a quality smoothness through frames is also observed

Der volle Inhalt der QuelleCytotoxic lymphocytes rely on actin cytoskeleton remodeling to achieve their function. In particular cytotoxic T lymphocytes and NK cells assemble the immunological synapse (IS), a complex actin-rich structure that allows the interaction with target cells, such as infected cells or tumor cells, and permits the polarized delivery of lytic granules. Although actin cytoskeleton remodeling is known to be a driving force of IS assembly and dynamics, our understanding of the molecular control of actin remodeling sustaining IS dynamics remains fragmented. This PhD project consisted in developing a high-content imaging approach to unbiasedly define the metrics of IS from human T and NK lymphocytes and to characterize the requirements for actin cytoskeleton integrity in organizing the IS architecture.For that purpose, the stimulation and staining of cell lines and primary cells in multiwell plates and acquisition of a unique set of >100.000 confocal images with a fully automatized high-content imager was optimized. The images were analyzed with two complementary CellProfiler analytical pipelines to characterize the morphological features associated with different treatments and disease status. We first extracted 16 morphological features pertaining to F-actin, LFA-1 or lytic molecules based on prior knowledge of IS assembly, and included features pertaining to the nucleus. We show that IS assembly in Jurkat and NK-92 cells is characterized by increased F-actin intensity and cell area. For Jurkat cells, we report an increase in LFA-1 intensity and surface area, and for NK-92 cells an increase in lytic granule detection at the IS plane. We then treated NK-92 cells with seven drugs known to affect different aspects of actin dynamics and investigated the associated effects on IS features. We report concentration dependent effects, not only on F-actin intensity, as expected, but also on lytic granule polarization. Furthermore, using a high-resolution morphological profiling based on >300 features, we show that each drug inflicts distinct alterations of IS morphology. In a next step, we applied our experimental pipeline to primary NK cells isolated from the blood of healthy donors. Distinct morphological features were characterized among the NK cells from different donors, highlighting the sensitivity of our approach, but also revealing an unsuspected variability of immune cell morphologies among donors. We then further applied our approach to primary CD8+ T cells from patients with a rare immunodeficiency due to mutations in the gene encoding the actin regulator ARPC1B. ARPC1B deficiency results in decreased F-actin intensity, as well as in lytic granule polarization. This prompted us to assess the ability of these cells to kill target cells, which was markedly reduced. These results illustrate how the systematic analysis of the IS might be used to assist the exploration of fonctional defects of lymphocyte populations in pathological settings. In conclusion, our study reveals that although assembly of the IS can be characterized by a few features such as F-actin intensity and cell spreading, capturing fine alterations of that complex structure that arise from cytoskeleton dysregulation requires a high-content analysis. The pipeline we developed through this project holds promises for the morphological profiling of lymphocytes from primary immunodeficiency patients whose genetic defect has not yet been identified. Moreover, the discriminative power of our high-content approach could be exploited to characterize the response of lymphocytes to various stimuli and to monitor lymphocyte activation in multiple immune-related pathologies and treatment settings

Der volle Inhalt der QuelleThe Non-Binary Low Density Parity Check (NB-LDPC) codes constitutes an interesting category of error correction codes, and are well known to outperform their binary counterparts. However, their non-binary nature makes their decoding process of higher complexity. This PhD thesis aims at proposing new decoding algorithms for NB-LDPC codes that will be shaping the resultant hardware architectures expected to be of low complexity and high throughput rate. The first contribution of this thesis is to reduce the complexity of the Check Node (CN) by minimizing the number of messages being processed. This is done thanks to a pre-sorting process that sorts the messages intending to enter the CN based on their reliability values, where the less likely messages will be omitted and consequently their dedicated hardware part will be simply removed. This reliability-based sorting enabling the processing of only the highly reliable messages induces a high reduction of the hardware complexity of the NB-LDPC decoder. Clearly, this hardware reduction must come at no significant performance degradation. A new Hybrid architectural CN model (H-CN) combining two state-of-the-art algorithms - Forward-Backward CN (FB-CN) and Syndrome Based CN (SB-CN) - has been proposed. This hybrid model permits to effectively exploit the advantages of pre-sorting. This thesis proposes also new methods to perform the Variable Node (VN) processing in the context of pre-sorting-based architecture. Different examples of implementation of NB-LDPC codes defined over GF(64) and GF(256) are presented. For decoder to run faster, it must become parallel. From this perspective, we have proposed a new efficient parallel decoder architecture for a 5/6 rate NB-LDPC code defined over GF(64). This architecture is characterized by its fully parallel CN architecture receiving all the input messages in only one clock cycle. The proposed new methodology of parallel implementation of NB-LDPC decoders constitutes a new vein in the hardware conception of ultra-high throughput rate decoders. Finally, since the NB-LDPC decoders requires the implementation of a sorting function to extract P minimum values among a list of size Ns, a chapter is dedicated to this problematic where an original architecture called First-Then-Second-Extrema-Selection (FTSES) has been proposed

Der volle Inhalt der QuelleThis memoir describes work concerning the treatment and analysis of high-throughput mass spectrometry. Mass spectrometry is a tried and tested method of chemical measurement in a sample. Applied to biological samples, mass spectrometry becomes a metabolomic measurement technique, meaning that it measures the metabolites contained in a sample, which are small molecules present in the biological fluid that interact with the individual’s metabolism. The project that is presented here is a partnership with Hema-Québec in order to conceive new quality control tests from mass spectrometry measurements. The application of the LDTD ionisation source in mass spectrometry makes the acquisition of spectra in high-throughput possible. This represents a large benefit in terms of experimental costs and in time. Large datasets of mass spectra can then be obtained in a short period of time. The computer science domain of machine learning can then be applied to this data. Statistical machine learning can then be used to classify the spectra of blood product samples and provide statistical guarantees on this classification. The use of sparse and interpretable machine learning algorithms can also lead to the discovery of biomarkers. The work presented in this memoir concerns the design of two methods of treatment of mass spectra. The first of these methods is the correction by virtual lock masses, used to correct any uniform shift in the masses in a spectra. The second is a new method of peak alignment used to correct slight measuring errors. In addition, a new kernel method, a method to mathematically compare examples, was designed specifically for application on mass spectra data. Finally, results of classification on mass spectra acquired with an LDTD ionisation source and by liquid chromatography mass spectrometry will be presented.

Der volle Inhalt der QuelleDetection of pathogens becomes an increasing challenge, since infectious diseases represent major risks for both human and animal health. Globalization of trade and travels, evolution of farming practices and global climatic changes, as well as mass migrations are impacting the biology of pathogens and their emerging potential. This manuscript describes three approaches, based on three innovative technologies of molecular biology applied to the detection of pathogens in three different settings : (i) detection of a list of pathogens using real-time quantitative PCR on a microfluidic platform, (ii) unbiased detection of pathogens in complex matrix, using metagenomics and Illumina (Miseq) sequencing and (iii) genotyping of pathogens without isolation of PCR-enrichment using a 3rd generation NGS (Next Generation Sequencing) platform MinION from Oxford Nanopore Technologies. The three studies shown the contribution of these techniques, each representing distinctive features, suitable for the respective applications. Beyond application of these techniques to the field of microbial diagnostics, their use for the control of veterinary immunological drugs is a priority of this project. Veterinary vaccines are not only submitted to mandatory detection of listed pathogens to be excluded, but also to validation of the genetic identity of vaccine strains. The exponential availability and performances of new PCR or sequencing technologies open cutting-edge perspectives in the field of microbial diagnostic and control

Der volle Inhalt der QuelleInternet monitoring has only been used for research, engineering and design of Internet networks since few years (since the beginning of years 2000), but it is more and more popular and spreads rapidly. It deals with studying, characterizing, analyzing and modeling traffic on the different Internet links in order to understand network behaviors when facing traffics which are largely unknown at this time. In particular, guarantying QoS for the Internet is currently one of the most challenging issues. This thesis aims at designing new communication protocols and architectures able to reduce the traffic LRD in order to optimize the use of communication resources. Then, new protocol and architectural mechanisms could be perfectly suited to users’ needs and traffic constraints. Thus, this PhD work deals with a new approach for the Internet, aiming at improving traffic management, QoS and more generally network services. This approach, called Measurement Based Networking (MBN), is built on the use of active and passive monitoring techniques to evaluate in real time different network parameters and analyze its traffic in order to react very quickly and accurately to specific events arising in the network (for instance, congestion events). We will illustrate, in particular, the MBN approach by designing a new measurement based congestion control mechanism (MBCC) which will be evaluated thanks to NS-2 simulations. We will show, in particular, how this new mechanism can improve traffic characteristics as well as Internet QoS, despite the complexity and variability of current Internet traffics

Der volle Inhalt der QuelleNowadays, the manufacture of turbomachinery is conditioned by more and more restrictive rules. The industrial challenge for researchers has to consider optimal solutions to reduce sources of energy loss, instability and noise, particularly the tip clearance flow (leakage flow rate). Preliminary actions have been developed at Arts & ParisTech on rotational molding process used for the automobile cooling axial fan. The idea of this work is to use the hollow shape induced by rotational molding process in order to exploit it in the control of tip clearance flow through rotary steady air injection. For this, the shroud ring is composed of injection holes oriented in such away to reduce both of leakage flow rate and the torque. In this work, the thesis focuses on three parts. The first concerns the build of the fan by rotational molding process. The second concerns the experimental study carried out in the ISO 5801 test bench. This study involves the realization of drive system dedicated to rotary steady air injection, metrology for performance determination and the characterization of the near wake axial velocity. The third part deals with the numerical modeling of efficient experimental conditions, then the extrapolation of work towards high injection rates. For this latter, it is possible to cancel leakage flow rate with a considerable gain of the torque thus putting the fan in autorotation

Der volle Inhalt der QuelleMany mechanisms control and limit the proliferation of transposable elements (TEs) which could otherwise threaten the structural and functional integrity of the genome. In plants RNA interference (RNAi) plays an important role in this control through small RNAs that guide the expression regulation of endogenous or exogenous sequences by two types of mechanisms. The first such mechanism, shared by many eukaryotic organisms, acts at the post-transcriptionnal level to inhibit the activity of mRNA. A second type of regulation allows the transcriptional control of TEs activity through a mechanism called RNA directed DNA methylation (RdDM) which involves 24nt long siRNA ("short-interfering RNA") that guide DNA methylation specifically on TEs sequences. Furthermore, siRNAs are also involved in the progressive restoration of DNA methylation after a loss induced by mutation of the DDM1 gene (Decrease in DNA Methylation 1). The aim of this thesis is to take advantage of high-throughput sequencing technologies to characterize these TEs controls mechanisms by siRNA in the model plant Arabidopsis thaliana .At first, I developed methods and bioinformatics tools to effectively manage data produced by high-throughput sequencing of small RNA libraries. These tools, combined in a pipeline, are designed to allow the study the accumulation of siRNA corresponding to TE sequences or TE families as well as their global or detailed visualization.These tools were applied to characterize, in a wild type background, the association between siRNA and TEs in order to define factors that may explain the observed differences in siRNA abundance . These analyses were performed by taking into account both DNA methylation states and genomic context. It provides a static view of siRNA control of TEs and their impact on nearby genes. Then, analysis of small RNA libraries from mutants of the RNAi pathway was performed to better characterize the impact of DNA methylation loss on siRNA populations and to define the mechanisms involved in the production of 21nt siRNA induced in the ddm1 mutant. These comparative analyses of the TE control after loss of DNA methylation allow us to highlight the production of 24nt siRNA independently of the classical RdDM pathway and to propose a model explaining the production of 21nt siRNA in the ddm1 mutant. At last, I tried to clarify the involvement of siRNA in the restoration of DNA methylation. Changes in DNA methylation induced by ddm1 mutation were characterized as well as their transgenerational stability in an epiRIL population. The stability of DNA hypomethylation has been studied in relation to high-throughput sequencing of small RNAs data from WT, ddm1 and 4 epiRIL lines. It provides a temporal view of the TE control by siRNA. The results highlight the important role of small RNAs in the control of transposable elements in order to preserve structural and functional integrity of the genome through a variety of mechanisms depending on TE sequences. This work opens the way to the analysis of the siRNA control on TEs based on approaches that combine TEs in networks based on their shared siRNA sequences. It would allow to study "siRNA-connections" between TEs in order to explore, for example, the action in trans of siRNA in the restoration of DNA methylation defect

Der volle Inhalt der QuelleAinsi, nous avons montré que ce sont les protocoles basés sur l'assistance de routeurs fournissant aux émetteurs un taux d'émission explicite (``Explicit Rate Notification'' - ERN) partagent mieux les ressources du réseaux entre les utilisateurs et évitent mieux la congestion que les protocoles de bout-en-bout (comme les protocoles basés sur TCP). Cependant, l'absence d'inter-opérabilité des protocoles ERN avec les routeurs non-ERN (par exemple, les routeurs DropTail) et les protocoles de congestion de bout-en-bout (comme TCP), empêche leur mise en place dans les réseaux actuels.
Pour résoudre les problèmes d'inter-opérabilité des protocoles ERN avec des routeurs non-ERN, nous avons proposé des stratégies et des mécanismes capables de détecter les groupes des routeurs non-ERN entre deux routeurs ERN, d'estimer la bande passante minimale disponible à l'intérieur de ces groupes, et de créer des routeurs virtuels qui remplacent chaque groupe de routeurs non-ERN par un routeur ERN.
Nous avons également proposé un système d'équité intra-protocolaire entre les protocoles ERN et les protocoles de bout-en-bout. Avec notre solution, les routeurs ERN dans une première étape estiment les besoins en terme de bande passante des flux ERN et non-ERN puis, dans une deuxième étape, limitent le débit des flux non-ERN en rejetant leurs paquets avec une probabilité qui dépend des résultats de la première étape.
Le succès des protocoles ERN est basé sur l'information de rétroalimentation, calculée par les routeurs, et renvoyée par les récepteurs aux émetteurs. Nous avons montré que les protocoles ERN deviennent instables face aux pertes de l'information de rétroalimentation dans des environnements hétérogènes et à bande passante variable. Dans ce cadre là, nous avons proposé une nouvelle architecture qui améliore la robustesse des protocoles ERN, ainsi que la réactivité des émetteurs.
Toutes nos propositions, applicables sur d'autres protocoles ERN, ont été expérimentées et validées sur le protocole eXplicit Control Protocol (XCP). Ainsi, nous avons montré que nos solutions surmontent les défis concernant les problèmes d'inter-opérabilité des protocoles ERN dans un grand nombre des scénarios et de topologies.
De cette façon, nous avons développé les bases pour bénéficier d'un protocole ERN capable d'être déployé dans des réseaux hétérogènes à grand produit bande passante - délai où le transfert de grande quantité des données est nécessaire, tels que les réseaux de grilles (ex. GÉANT).

Genetic and genomic studies were carried out in addition to histological measuremnets to better understand the etiology of these defects and to contribute to the development of new indicators useful for diagnosis and selection. Studies focused on two complementary genetic models : 1) two divergent chicken lines selectied on breast meat ultimate pH and 2) a line with strong muscular development more severely affected by the defects, qwhich was studied in comparison with a slow-growing strain free from lesions. The thesis helped to describe the metabolic and structural changes observed in case of severe myopathies. It also led to the identification of the first QTL regions controlling muscular defects in chicken and to the establishment of a set of genes correlated with histological measurements of myopathies that will serve after validation as tool for selection and breeding

Der volle Inhalt der QuelleDealer or owner operator of electricity production structures, EDF is responsible for their operation in safe condition and for the respect of the limits imposed by the regulations. Thus, the knowledge of water resources is one of EDF main concerns since the company remains preoccupied about the proper use of its facilities. The knowledge of streamflow is one of its priorities to better respond to three key issues that are plant safety, compliance with regulatory requirements, and optimizing the means of production. To meet these needs, EDF-DTG (Division Technique Générale) operates an observation network that includes both climatic parameters such as air and temperature, then the precipitations and the snow, but also the streamflow. The data collected allows real time monitoring of rivers, as well as hydrological studies and the sizing of structures. Ensuring the quality of the stream flow data is a priority. Up to now it is not possible to measure continuously the flow of a river since direct measurements of discharge are time consuming and expensive. In common cases the flow of a river can be deduced from continuous measurements of water level. Punctual measurements of discharge called gaugings allow to develop a stage-discharge relationship named rating curve. These are permanently installed equipment on rivers for measuring levels that are called hydrometric station. It is clear that the whole process constitutes an indirect way of estimating the discharge in rivers whose associated uncertainties need to be described. Quantification of confidence intervals is however not the only problem of the hydrometer. Fast changes in the stage-discharge relationship often make the streamflow real time monitoring quite difficult while the needs of continuous high reliability data is obvious. The historical method to produce the rating curve based on a construction from a suffcient number of gaugings chronologically contiguous and well distributed over the widest possible range of discharge remains poorly adapted to fast or cyclical changes of the stage-discharge relationship. The classical method does not take suffciently into account the erosion and sedimentation processes as well as the seasonal vegetation growth. Besides, the ability to perform gaugings by management teams generally remains quite limited. To get the most accurate streamflow data and to improve their reliability, this thesis explores an original dynamic method to compute rating curves based on historical gaugings from a hydrometric station while calculating the associated uncertainties. First, a dynamic rating curve assessment is created in order to compute a rating curve for each gauging of a considered hydrometric station. After the tracing, a model of uncertainty is built around each computed rating curve. It takes into account the uncertainty of gaugings, but also the uncertainty in the measurment of the water height, the sensitivity of the stage discharge relationship and the quality of the tracing. A variographic analysis is used to age the gaugings and the rating curves and obtain a final confidence interval increasing with time, and actualizing at each new gauging since it gives rise to a new rating curve more reliable because more recent for the prediction of discharge to come. Chronological series of streamflow data are the obtained homogeneously and with a confidence interval that takes into consideration the aging of the rating curves. By taking into account the variability of the flow conditions and the life of the hydrometric station, the method can answer important questions in the field of hydrometry such as « How many gauging a year have to be made so as to produce stream flow data with an average uncertainty of X\% ? » and « When and in which range of water flow do we have to realize those gaugings ? »

Der volle Inhalt der QuelleThe work presented in the thesis is directed towards addressing the requirement for determining the radio frequency (RF) exposure due to mobile phones under typical usage/ real-life scenarios and also to develop a method to predict and compare mobile phones for their real-life RF exposure. The mobile phones are characterized for their specific absorption rate (SAR) and for transmit and receive performance given by the over-the-air (OTA) characterization. Using the SAR and the total radiated power (TRP) characterization, an exposure index referred to as the SAROTA index was previously proposed to predict the real-life exposure due to mobile phones which would also serve as a metric to compare individual phones. In order to experimentally determine the real-life RF exposure, various software modified phones (SMP) are utilized for the study. These phones contain an embedded software capable of recording the network parameters. The study is undertaken in the following order: (a) Characterization of the available tools and resources for performing targeted measurements/experiments, (b) identifying the important radio resource parameters and metrics to perform the targeted measurements, (c) investigation of the actual implementation of the power control mechanism in a live network for various received signal level and received quality environments, (d) investigating the correlation of the over-the-air performance of the mobile phones and the extent of actual power control realization, (e) comparing the actual exposure and the real-life exposure as predicted by the SAROTA index. Based on the logistical and technical challenges encountered, the experiments were restricted to indoor environments to enable repeatability. During the first phase of the study, the stability of the indoor environment was evaluated. During the second phase, the influence of hand phantom on the SAR and TRP of the mobile phones and the capability of the SAROTA index to predict the exposure was investigated. Further developing on the insights from the hand phantom experiments, in the third phase, a set of identical software modified phones were externally modified to alter the TRP performance and the methodology to determine the real-life exposure and also verify the capability of the SAROTA index to predict the exposure levels was investigated. The experiments demonstrate that the SAROTA index is capable of predicting the real-life exposure and comparing the mobile phones

Der volle Inhalt der QuelleNowadays, the architecture of the mobile network is in full evolution to ensure the increase in terms of bit rate between the Central (CO) (core networks) and various terminals such as mobiles, computers, tablets in order to satisfy the users. To address these challenges of the future, the C-RAN (Cloud or Centralized-RAN) network is known as a 5G solution. In the C-RAN context, all BBUs (Base Band Units) are centralized in the CO, only the RRH (Remote Radio Head) remain at the head of the base station (BS). A new segment between BBUs and RRHs appears called "fronthaul". It is based on D-ROF (digital radio-overfiber) transmissions and carries the digital radio signal at a high bit rate using the Common Public Radio Interface (CPRI) protocol. Taking into account CAPEX and OPEX, the ANR LAMPION project has proposed the Self-seeded Reflective Semiconductor Optical Amplifier (RSOA) technology in order to make the solution more flexible and overcome the need for colored transmitters / receivers in the context of PON-WDM (Wavelength Division Multiplexing Passive Optical Network). Nevertheless, it is necessary to add a FEC (forward error corrector) in the transmission to ensure the quality of service. So the objective of this thesis is to find the most suitable FEC to apply in the C-RAN context. Our work has focused on the use of LDPC codes, chosen after performance comparisons with other types of codes. We have specified the parameters (code performance, matrix size, cycle, etc.) required for LDPC codes to obtain the best performance. Hard-decision LDPC algorithms were chosen after considering the tradeoff between circuit complexities and performance. Among these hard-decision algorithms, the GDBF (gradient descent bit-flipping) was the best solution. Taking into account a CAN 2-Bit in the channel led us to propose a variant: the BWGDBF (Balanced weighted GDBF). Optimizations have also been made with respect to the convergence of the algorithm and latency. Finally, we managed to implement our own algorithm on the Spartan FPGA 6 xc6slx16. Several methods have been proposed to achieve a latency of 5 μs desired in the C-RAN context. This thesis was supported by the project ANR LAMPION (Lambada-based Access and Metropolitan Passive Optical Networks)

Der volle Inhalt der Quelle[The congestion control protocols aim to fairly share the network resources between users and avoid congestion. In this thesis, we have shown that the routers-assisted protocols providing explicit rate notification (ern protocols) accomplish those goals better than end-to-end protocols (e. G. Tcp-based protocols). However, ern protocols, like the explicit control protocol (xcp), are not interoperable with current technologies. Thus, ern protocols cannot be gradually deployed in current networks. Our research in this thesis resulted in a set of solutions that allow ern protocols to be tcp-friendly, robust against losses of routers informations and interoperable with non-ern networks equipments in a wide range of scenarios. Thus, we provided the basis for creating an ern protocol able to be gradually deployed in current heterogeneous high speed networks, where users frequently move very large amount of data]

Der volle Inhalt der QuelleThe acquisition and delivery of video content with minimal latency has become essential in several business areas such as sports broadcasting, video conferencing, telepresence, remote vehicle operation, or remote system control. The live streaming industry has grown in 2020 and it will expand further in the next few years with the emergence of new high-efficiency video codecs based on the Versatile Video Coding (VVC) standard and the fifth generation of mobile networks (5G).HTTP Adaptive Streaming (HAS) methods such as MPEG-DASH, using algorithms to adapt the transmission rate of compressed video, have proven to be very effective in improving the quality of experience (QoE) in a video-on-demand (VOD) context.Nevertheless, minimizing the delay between image acquisition and display at the receiver is essential in applications where latency is critical. Most rate adaptation algorithms are developed to optimize video transmission from a server situated in the core network to mobile clients. In applications requiring low-latency streaming, such as remote control of drones or broadcasting of sports events, the role of the server is played by a mobile terminal. The latter will acquire, compress, and transmit the video and transmit the compressed stream via a radio access channel to one or more clients. Therefore, client-driven rate adaptation approaches are unsuitable in this context because of the variability of the channel characteristics. In addition, HAS, for which the decision-making is done with a periodicity of the order of a second, are not sufficiently reactive when the server is moving, which may generate significant delays. It is therefore important to use a very fine adaptation granularity in order to reduce the end-to-end delay. The reduced size of the transmission and reception buffers (to minimize latency) makes it more difficult to adapt the throughput in our use case. When the bandwidth varies with a time constant smaller than the period with which the regulation is made, bad transmission rate decisions can induce a significant latency overhead.The aim of this thesis is to provide some answers to the problem of low-latency delivery of video acquired, compressed, and transmitted by mobile terminals. We first present a frame-by-frame rate adaptation algorithm for low latency broadcasting. A Model Predictive Control (MPC) approach is proposed to determine the coding rate of each frame to be transmitted. This approach uses information about the buffer level of the transmitter and about the characteristics of the transmission channel. Since the frames are coded live, a model relating the quantization parameter (QP) to the output rate of the video encoder is required. Hence, we have proposed a new model linking the rate to the QP of the current frame and to the distortion of the previous frame. This model provides much better results in the context of a frame-by-frame decision on the coding rate than the reference models in the literature.In addition to the above techniques, we have also proposed tools to reduce the complexity of video encoders such as VVC. The current version of the VVC encoder (VTM10) has an execution time nine times higher than that of the HEVC encoder. Therefore, the VVC encoder is not suitable for real-time encoding and streaming applications on currently available platforms. In this context, we present a systematic branch-and-prune method to identify a set of coding tools that can be disabled while satisfying a constraint on coding efficiency. This work contributes to the realization of a real-time VVC coder

Der volle Inhalt der QuelleAlthough the human ventilatory flow resembles a periodic phenomenon, it is not and is truly chaotic. This means that the trajectory of the flow is bounded and depends on deterministic processes, but at the same time, is also complex, sensitive to the initial conditions and unpredictable in the long-term. The theory of chaos provides mathematical tools for quantifying these characteristics. However, physiological significance and clinical interest of ventilatory chaos will depend on its source that is unclear. The gaol of this thesis was thus to contribute to its identification. By comparing, in humans, the ventilatory flow recorded at the mouth with a pneumotachometer to that reconstructed by inductive plethysmography, we showed that neither the respiratory route (nose or mouth), nor the recording technique affected the nature of chaos, even if they changed its complexity. Therefore, they could not be its origin. Inspiratory threshold or resistive loading changed neither the nature nor the features of the chaotic dynamics of the ventilatory flow, though respiratory compensation of these kinds of load depends on the pre-motor cortex. The latter is probably not a source of ventilatory chaos either. We finally showed that the neural respiratory output of in vitro isolated brainstems of post metamorphic tadpoles was always chaotic. Stimulation of this output by CO2 augmented the intensity of chaos. Chaos was rarely found in pre-metamorphic preparations, suggesting ontogenetic changes. In conclusion, the intrinsic properties of the automatic ventilatory command, located in the brainstem, could be a sufficient source of ventilatory chaos

Der volle Inhalt der QuelleThe Smart Grid is an important part of the third technological revolution. The final client is now able to improve his energy consumption efficiency via the control of the domestic appliances. The narrowband power lines protocols are adopted by many international utilities and DSO to ensure the control of the distribution power grid. In this thesis, we propose to use theses protocols for domestic electrical grid management. To assess the performances of the narrowband PLC systems in domestic environment, we have realized two measurements campaigns in many houses. The first campaign is dedicated to the domestic PLC channel response in the band of [9kHz-500kHz]. The measurements are classified into 5 classes according to their transmission capacities. To model the channel measurements, a modeling approach based on FIR filters is adopted. The second measurements campaign aims to characterize and to reproduce the PLC domestic noise in the band of [9kHz-500kHz]. The measurements are classified into stationary noise, periodic noise and aperiodic noise. Some examples of noise generation are proposed for every form of noise

Der volle Inhalt der QuelleThe rainfall-runoff transformation is characterized by the complexity of the involved processes and by the limited observability of the atmospheric forcing, catchment properties and hydrological response. It is therefore essential to understand, analyse and reduce the uncertainty inherent to hydrological modelling (sensitivity and uncertainty analysis, data assimilation). Variational methods are widely used in other scientific disciplines (ex. Meteorology, oceanography) facing the same challenges. In this work, they were applied to hydrological models characterised by different modelling paradigms (reductionist vs. Systemic) and runoff generation mechanisms (infiltration-excess vs. Saturation excess). The potential and limitations of variational methods for catchment hydrology are illustrated with MARINE from the Toulouse Fluids Mechanics Institute (IMFT) and two models (event based flood model and continuous water balance model) based on TOPMODEL concepts developed at the Laboratory of Environmental Hydrology (LTHE). Forward and adjoint sensitivity analysis provide a local but extensive insight of the relation between model inputs and prognostic variables. The gradient of a performance measure (characterising the misfit with observations), calculated with the adjoint model, efficiently drives a bound-constrained quasi-newton optimization algorithm for the estimation of model parameters. The results obtained are very encouraging and plead for an extensive use of the variational approach to understand and corroborate the processes described in hydrological models but also estimate the model control variables (calibration of model parameters and state estimation using data assimilation)

Der volle Inhalt der QuelleUnderstanding Neapolitan lay people’s faith in the sixteenth century is an arduous undertaking, both because of the material difficulties of accessing sources and because of their temporal discontinuity, which makes it difficult to carry out any historical systematic reconstruction based on the long term, orto study homogeneous series of sources. In spite of this reality, material difficulties have been overcome by systematically examining a wide variety of collections, both from the archdiocesan and state archivesof Naples, the General Curia (Curia Generalice) of the Society of Jesus, and the Holy See, using aqualitative methodology.The particular characteristics of a lay and urban piety were first privileged, then the analysis focused on the relations between laymen and ecclesiastics in the capital of the vice-kingdom of Spain before and after the Council of Trent. In fact, the diachronic approach chosen focuses on the "transitional century"of the history of the modern Catholic Church, that of the 16th century.From this thesis emerges the reconstruction of multiple religious identities of Neapolitan laymen and clergymen, as well as their way of apprehending religion and the Catholic Church, thanks to the precious elements provided by the examination of the Tridentine pastoral visits, or of the more or less repressive one of the minutes of the archdiocesan tribunals and of the "Neapolitan Inquisition" of the Holy Office.Thus, Neapolitans were reluctant to apply the Tridentine norms, increasing a context of growing social tension and religious criminalisation. This is also demonstrated by the essential sources for the historyof religious sensitivity, in this case the minutes of the vigil of capital executions of laymen, drawn up by the "clerks" of the Company of the Bianchi della Giustizia. Faced with this situation, strategies were implemented by the General Curia and those in charge of the Neapolitan Jesuit College, in order toreform religious life, which was very contrasted according to the sources of the Curia of the archdiocesetoo. Finally, laymen and clerics often made common cause in the face of attempts at Roman reform,which was not that different from most Catholic European cities.This thesis shows a city religion that is still "very medieval", - in all likelihood rooted in a Byzantine heritage -, testifying to strong local lay and ecclesiastical resistance, making the introduction of the new model of Christian life very laborious in the capital of the Kingdom of Naples until the 1598’s reformof Cardinal and Archbishop Alfonso Gesualdo

Der volle Inhalt der QuelleThe object of this thesis is the elaboration of analogues of these compounds and the evaluation of their antioxidizing properties, as well as their toxicity, to use them as a protective agent. An original and effective method was finalized to synthetize these compounds. A silylated product is synthesized from one acetate, then it is condensed on the oxalyl chloride. The lactone is isolated, after treatment of intermediate compound obtained with the DBU in dichloromethane. The ester is then saponified, to lead to the pulvinic acid. Several pulvinic acids (aromatics or heterocyclics) are obtained with good yields. Derivatives substituted by alkyl groups are obtained with weaker yields. Pulvinic acids were tested to determine their radioprotective properties. At the same time, we setup a strategy of synthesis of dissymmetrical pulvinic acids by making successively condensation of two different silylated derivatives. Another method was setup by making reactions between two different silylated of ketene acetal, however the yield was low. Various derivative amids of pulvinic acids more soluble were synthesized from bis-lactone, which were tested. A test of evaluation of the antioxidizing activity with thymidine and plasmids under the effect of different oxidizing stress was made. Several aromatic pulvinic derivatives revealed a high activity. The microscopy of samples containing of the DNA of plasmid brought together with pulvinic derivatives, irradiated and not irradiated, showed a compaction of the DNA

Der volle Inhalt der QuelleThis research deals with the financial control experiences of the french and the russian monarchies for the second part of the 17th century and for the beginning of the 18th century. In order to reconstruct the control system and its evolution related to the historical, financial and geographical different contexts, systematic studies of its notions, its institutional forms and its procedures are performed. This research deals with the development of the control under "technical" considerations of the financial system itself, as well as its relationship with the political and social domains to contribute to the important problem on the genesis of the "modern" state. On another hand, this contribution yields an exemplary framework for studying under an unusual point of view all the relatively unknown aspects of the history of the monarchical finances, their historical foundations as well as their pratices with respect to the administrative and fiscal reforms process lived by the Europe for the second part of the 17th century and at the beginning of the 18th century

Der volle Inhalt der QuelleIn the first part of the XIXth century, the prohibition of the slave trade and later the abolition of slavery forced the landowners of Reunion Island and Mauritius Island to use a newtype of labour : indentured workers. More than 600 000 persons landed mainly recruted from India, but also from other parts of the world such as China, South East Asia, East Africa, Madagascar, the Comoros Islands or Rodrigues Island. To protect the colonies against infectious diseases, the governments of London and Paris commanded the governors of Mauritius and Reunion islands to enforce locally the sanitary regulations applied in aminland territories. The arrival of indentured labourers from countries where plague, smallpox and cholera were considered as endemic, led to the reinforcement of sanitary controls on arrival. The inspection of vessels and quarantine on board or in lazarets were the principal measures of this sanitary control policy, because the origin and the form of these diseases were not yet known. At the end of the 1850s, with the massive introduction of indentured labourers and the internalisation of the fight against infectious diseases, permanent quarantine lazarets were built on Mauritian flat island and at La Grande Chaloupe in Reunion Island. In this french colony, an initial "observation quarantine" was systematically imposed on indentured labourers for ten days. At the end of the XIXth century although the landing of indentured workers declined, medical brekthroughs in the field of viruses and bacteriums pardoxically increased the number of diseases subjected to quarantine control. As a result lazarets remained an important component of sanitary control on arrival until the end of the 1930's

Der volle Inhalt der QuelleThis work is a research in psychopathology- that focuses on child schizophrenia. It addresses the probiem of children suffering major disruption of their mental life which is not included in the current international classifications (DSM and CIM). The theme developed here is the encounter between clinician and patient, using psychoanalytic models and including the concept of transference psychosis and the principle of transference (a transference psycbosis) immediate and spontaneous in chidren, winch would allow to recognizec the inestimable value of the first interviews. The notions of transference, countertransference and affect are the basis of the reflexion of this work. These concepts differs from psychiatry categories, which far from representing the suffering and the clinical issues associated with the psychopathological' field would be at the origin of the "nosographic entanglement". The methodology used is the analytical play for diagnostic purposes, which would promote the establishment of a brief transference-countertransference linkage but very useful for the implantation of a psychodynamic diagnosis, thatt is, that includes mechanisms, anxieties and fantasies acting Within the child. The results consist mainly on the specificity of the play led by these young patients, by definition strange and always unexpected, and being the heart of the transference phenomenon
