A new class of supramolecular networks, where the crosslink points are not fixed but sliding, has been recently proposed and developed by Okumura and Ito. Their structure is based on intermoleculary crosslinked α-cyclodextrins / poly(ethylene-glycol) precursor polyrotaxanes. The intermolecular crosslinking between the polyrotaxane precursors leads to the formation of a supramolecular sliding network, the sliding gel. These specific networks are synthesized in two main steps: i) the formation of polyrotaxane precursors where the macrocycles are threaded along a template polymer chain; ii) the intermolecular crosslinking of some macrocycles. The sliding gels are expected to have very unusual physical / mechanical properties due to the theoretical ability of the crosslink points to slide along the polymer chain. The aim of this PhD work is to have more insight into the original properties of the sliding gels. For this purpose a controlled synthesis of the topological networks have been carried out and leads to a control of the complexation degree of the polyrotaxanes and of the crosslinking density of the topological network. The characterization of the sliding gels was carried out In order to explain the structure / properties relationships and to highlight on the sliding motion of the crosslink points. In particular the viscoelastic behaviour of the sliding gels in DMSO at low frequencies has revealed all the potential of the sliding crosslink points and underlines the high ability to relax with very low viscous dissipation of this material

This thesis revolves around a main subject : the theoretical study of the Kondo effect in heavy fermions when the magnetic impurity concentration is high. In the first part, the influence of the variation of the concentration of conducting electrons on the Kondo lattice is studied at low temperature (exhaustion problem). This effect can be observed experimentaly in some Cerium and Uranium compounds, whose coherence temperature can be considerably small compared to the predictions of single impurity models. The study is made both analyticaly and numericaly in the "large-N" limit, where N is the number of spin components. Whereas the single impurity models are caracterised at low temperature by a single energy scale, Tk, this thesis confirms the existence for the Kondo lattice of a second scale T*, caracterising the appearance of the Fermi liquid behavior. In the second part, the effects of disorder and magnetic frustration are studied analyticaly, within the dynamical mean field theory formalism, in the "large-N" limit. A quantum critical point (QCP) is obtained between a heavy Fermi liquid regime and a spin liquid regime. The physical properties of the system are computed in the Kondo phase. In particular, a strong decrease of T* and Tk is obtained in the vicinity of the QCP. This result is correlated with the large effective mass that has been experimentaly mesured for the compound LiV24. Finaly, the third part presents a preliminary study and the outline of the computation procedure leading to the numerical determination of the magnetic phase diagram of the periodic Anderson Model, using the dynamical mean field theory method
Hora, Diego Neves da. "Predicting home Wi-Fi QoE from passive measurements on commodity access points." Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066599/document.
Poor Wi-Fi quality can disrupt home users' internet experience, or the Quality of Experience (QoE). Detecting when Wi-Fi degrades QoE is valuable for residential Internet Service Providers (ISPs) as home users often hold the ISP responsible whenever QoE degrades. Yet, ISPs have little visibility within the home to assist users. This thesis designs and evaluates techniques to passively monitor Wi-Fi quality on commodity access points (APs) and predict when Wi-Fi quality degrades internet application QoE. Our first contribution is the design and evaluation of a method that estimates Wi-Fi link capacity. We extend previous models, suited for 802.11a/b/g networks, to work on 802.11n networks using passive measurements. Our second contribution is the design and evaluation of predictors of the effect of Wi-Fi quality on QoE of four popular applications: web browsing, YouTube, audio and video real time communication. Our third contribution is the design of a method to identify poor QoE events. We use K-means clustering to identify instances where the QoE predictors estimate that all studied applications perform poorly. Then, we classify poor QoE events as short, intermittent, and consistent poor QoE events. Finally, our fourth contribution is to apply our predictors to Wi-Fi metrics collected over one week from 832 APs of customers of a large residential ISP. Our results show that QoE is good on the vast majority of samples of the deployment, still we find 9% of poor QoE samples. Worse, approximately 10% of stations have more than 25% poor QoE samples. In some cases, we estimate that Wi-Fi quality causes poor QoE for many hours, though in most cases poor QoE events are short

Askri, Aymen. "The uplink reception and downlink transmission in MU-MIMO for 5G." Electronic Thesis or Diss., Institut polytechnique de Paris, 2021. http://www.theses.fr/2021IPPAT006.
Multiple-input multiple-output (MIMO) technologies were developed to increase system capacity and offer better link reliability. They allow a dense network architecture that will allow many users to connect in the same area without experiencing slowdowns. 5G networks and beyond will use these MIMO technologies with many small antennas allowing the beam to be focused on a given area. Coupled with high-frequency bands, the use of these antennas will significantly increase throughput.In such systems, multi-user (MU)-MIMO detection in the uplink reception and MU-MIMO precoding in the downlink transmission enable separating user data streams and pre-cancelling interference. However, some challenges have to be met under realistic conditions such as the reasonable complexity of the decoding and precoding processes, the erroneous channel knowledge, and the adjacent cell interference. This thesis addresses all these limitations above for the uplink reception and the downlink transmission in MU-MIMO systems.In the uplink reception, we study the well-known sphere decoding (SD) algorithm for MIMO detection. We seek to reduce its complexity which increases exponentially with the number of antennas and the constellation size. Thus, we profit from recent advances in neural networks (NNs) to develop the low-complexity NN assisted SD. We also propose the block recursive MIMO decoding, which achieves almost the maximum likelihood (ML) performance. Using deep neural networks (DNNs), we suggest a new and low complex scheme for signal processing and cloud-RAN (C-RAN) detection. This DNN scheme aims to mimic the whole transmission in uplink C-RAN, which considers the quantization constraints at the radio remote units (RRUs) and the corrupted observations at the central processor (CP).In the downlink transmission, we study the non-linear vector perturbation (VP) precoding. We design the combined VP to serve multiple users with different modulation coding schemes (MCSs). We also introduce the block VP algorithm, which merges both linear and non-linear precoding to offer a tunable tradeoff between complexity and performance. To deal with the erroneous channel state information (CSI) in the downlink precoding, we develop the new CSI accuracy indicator reporting to design a novel precoder that is less sensitive to CSI errors

A quantum paraelectric SrTiO3 is a material situated in close proximity to a quantum critical point of ferroelectric transition in which the critical temperature of ferroelectric state is suppressed down to 0 K. However, the understanding of the behaviour of the phase transition in the vicinity of this point remains challenging. Here we study the solid solutions based on the SrTiO3 to approach the pre-critical regions of the phase diagram and study the outcome of the coexistence of quantum fluctuations and thermal motion. It will allow the discovery of the novel phase statements and physical properties, occurring due to competition of quantum and classical regimes. We study the crystal structure and lattice dynamics of quantum paraelectric BaxSr1 xTiO3 solid solutions using X-Ray diffraction, Raman and terahertz-infrared (THz-IR)-spectroscopies in a temperature range 4-300K. The X-Ray diffraction and Raman spectroscopy reveal the cubic-to-tetragonal non-polar structural phase transition at about 100K. At the same time, Raman spectra manifest the presence of polar modes, TO2 and TO4, normally prohibited in paraelectric phase. Emergence of these modes indicates the appearance of the polar nanoregions in a broad temperature range. The modes become more intensive at low temperatures, the temperature dependence of their intensities on cooling reveals the kink-like change of the slope from flat to steep, indicating on activation of polar nanoregions. The transmission THz-IR-spectra show, that squared frequencies of the polar TO1 soft modes, responsible for the ferroelectric transition, follow the Cochran’s behavior at high temperatures. However, at low temperatures, it does not vanish at extrapolated Curie temperature but saturates, demonstrating the plateau feature below 20K. This behavior, coherent with the known saturation of the dielectric constant, indicates that transition to ferroelectric phase in BaxSr1-xTiO3 is suppressed by quantum fluctuations and system stays in the quantum paraelectric state at very low temperatures. Using the concentration of Pb in PbxSr1-xTiO3 solid solutions as a tuning parameter and applying the combination of Raman and dielectric spectroscopy methods we approach the quantum critical point in PbxSr1-xTiO3 and study the interplay of classical and quantum phenomena in the region of criticality. We obtain the critical temperature of PbxSr1-xTiO3 and the evolution of the temperature-dependent dynamical properties of the system as a function of x to reveal the mechanism of the transition. We show that the ferroelectric transition occurs gradually through the emergence of the polar nanoregions. We study also the cubic-to-tetragonal structural transition, occurring at higher temperatures, and show that its properties are almost concentration-independent and not affected by the quantum criticality. We also study the dielectric properties for the PbxSr1-xTiO3 in detail and show that in the composition with x = 0.005, a smooth plateau is observed in the temperature dependence of the dielectric permittivity. The height of the plateau depends on the Pb concentration and gradually decreases when x increases. This plateau arises due to random quantum fluctuations of the ions which dominate at low temperatures and concentrations. At higher x, the thermal fluctuations become more pronounced; therefore the plateau disappears
