Ravaioli, Riccardo. "Inférence active de la neutralité des réseaux". Thesis, Nice, 2016. http://www.theses.fr/2016NICE4044/document.
Testo completoIn the last decade, some ISPs have been reported to discriminate againstspecific user traffic, especially if generated by bandwidth-hungry applications(e.g., peer-to-peer, video streaming) or competing services (e.g. Voice-over-IP).Network neutrality, a design principle according to which a network shouldtreat all incoming packets equally, has been widely debated ever since. In thisthesis we present ChkDiff, a novel tool for the detection of trafficdifferentiation at the Internet access. In contrast to existing work, our methodis agnostic to both the applications being tested and the shaping mechanismsdeployed by an ISP. The experiment comprises two parts, in which we check fordifferentiation separately on upstream and downstream traffic that wepreviously dump directly from the user. In the upstream direction, ChkDiffreplays the user's outgoing traffic with a modified TTL value in order to checkfor differentiation on routers at the first few hops from the user. By comparingthe resulting delays and losses of flows that traversed the same routers, andanalyzing the behaviour on the immediate router topology spawning from theuser end point, we manage to detect instances of traffic shaping and attempt tolocalize shapers. Our study on the responsiveness of routers to TTL-limitedprobes consolidates our choice of measurements in the upstream experiment.In the downstream experiment, we replay the user's incoming traffic from ameasurement server and analyze per-flow one-way delays and losses, whiletaking into account the possibility of multiple paths between the two endpoints.Along the chapters of this thesis, we provide a detailed description of ourmethodology and a validation of our tool
Amiel, Stéphane. "Mesures de température de surface des composants face au plasma dans les Tokamaks". Thesis, Aix-Marseille, 2014. http://www.theses.fr/2014AIXM4736/document.
Testo completoDuring this PhD, the challenges on the non-intrusive surface temperature measurements of metallic plasma facing components in tokamaks are reported. Indeed, a precise material emissivity value is needed for classical infrared methods and the environment contribution has to be known particularly for low emissivities materials. Although methods have been developed to overcome these issues, they have been implemented solely for dedicated experiments. In any case, none of these methods are suitable for surface temperature measurement in tokamaks.The active pyrometry introduced in this study allows surface temperature measurements independently of reflected flux and emissivities using pulsed and modulated photothermal effect. This method has been validated in laboratory on metallic materials with reflected fluxes for pulsed and modulated modes. This experimental validation is coupled with a surface temperature variation induced by photothermal effect and temporal signal evolvement modelling in order to optimize both the heating source characteristics and the data acquisition and treatment. The experimental results have been used to determine the application range in temperature and detection wavelengths.In this context, the design of an active pyrometry system on tokamak has been completed, based on a bicolor camera for a thermography application in metallic (or low emissivity) environment.The active pyrometry method introduced in this study is a complementary technique of classical infrared methods used for thermography in tokamak environment which allows performing local and 2D surface temperature measurements independently of reflected fluxes and emissivities
Antoni, Rodolphe. "Optimisation des mesures d'interrogation neutronique active par couplage d'une méthode de correction des effets de matrice". Thesis, Grenoble, 2014. http://www.theses.fr/2014GRENY014.
Testo completoThe fissile mass in radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA La Hague reprocessing plant is measured by neutron interrogation with the Differential Die-away measurement Technique, on the waste compaction facility (ACC). In the future, old hulls and nozzles mixed with ion-exchange resins will be measured. The ion-exchange resins increase neutron moderation in the matrix, compared to the waste measured in the current process. In this context, a matrix effect correction method based on a drum monitor (3He proportional counter) has been studied. The feasibility of the method was first performed with the R&D measurement cell PROMETHEE 6, showing a good correlation between the monitor signal and the matrix effect correction, and the capability of MCNP simulations to reproduce experiments and to estimate the performances of the proposed correction. Therefore, the industrial implementation of the method and the assessment of its final performances have been studied by numerical simulation. Calculations demonstrate that the method allows keeping the highest error on the measured fissile mass below roughly a factor of 2, while the matrix effect without correction ranges on 2 orders of magnitude. In addition, the analysis of experimental data from the current process shows a good correlation between known physical properties of the matrix (moderation and absorption) and the monitor signal, demonstrating the reliability of the proposed approach. According to these satisfactory results, this correction method will be implemented on the industrial station. More generally, this method could be applied to similar waste measurement systems

Testo completoActive systems allow image acquisition both during day and night, with a highest resolution than the infra-red equipments do. Nevertheless, the main drawback of these systems compared to the classical optical sensors is that the obtained images are strongly corruptedby the speckle effect, and therefore their automatic interpretation is drastically limited. In this thesis, we propose to study in which way the Statistical Polygonal Snake (SPS) can be used in orderto perform the recognition of objects in speckled images. The recognition method which has been considered is the nearest neighbour algorithm; we select the reference which is the most similar to the silhouette obtained with the SPS by evaluating a given similarity function between contours

Testo completoOptical passive methods of temperature measurements such as thermography or optical pyrometry are very interesting because they allow a non-intrusive measurement with the target object provided to know the emission factor. The knowledge of this factor is critical for determining the actual temperature of a surface from the thermal radiation emitted in a wavelength band. The bichromatic pulsed pyrometer allows to overcome the knowledge of this parameter provided that precautions are taken in the choice of the values of wavelengths. When the object to be measured is placed in industrial environments, such passive optical methods are greatly disturbed by the presence of an optically absorbing medium. It is also distorted for objects located in very hot environments emitting intense interfering radiation. In this thesis, we present an active bichromatic radiometric method for measuring the temperature of a surface in harsh environments. The method is based on a localized excitation by a modulated laser source in the infrared range. Detecting the temperature range which is correlated with the excitation allows a synchronous detection to extract the signal embedded in a noise up to 106 times superior. Working at short wavelengths (visible range and near infrared range) offers a large dynamic range and minimizes the error due to variations in emissivity with the wavelength. This system collects the radiation emitted by the object at a distance from a few meters up to dozens of meters depending on the configuration of the optical system. The principle of the measurement method, the optical wavelength separation system and the telemetry apparatus are presented in this report as well as the theoretical and experimental study of the sensitivity of the device, its calibration and the results obtained in different industrial sites

Testo completoEmbedded security applications are diverse and at the center of all personal embedded applications. They introduced an obvious need for data confidentiality and security in general. Invasive attacks on hardware have always been part of the industrial scene. The aim of this thesis is to propose new solutions in order to protect embedded circuits against some physical attacks described above. ln a first part of the manuscript, we detail the techniques used to achieve side-channel, invasive attacks and reverse engineering. I could implement several of these attacks during my thesis research, they will be detailed extensively. ln the second part we propose different hardware countermeasures against side-channel attacks. The third part is dedicated to protection strategies against invasive attacks using active shielding and we conclude this work by proposing an innovative cryptographic shield which is faulty and dpa resistant

Testo completoLn the framework of radioactive waste drums control, difficulties arise in the non-destructive measurement of fissile mass 235U, 239PU. . . ) by Active Neutron Interrogation (ANI), when dealing with matrices containing materials (CI, H. . . ) influencing the neutron flux. The idea is to use the neutron capture reaction (n,y) to determine the matrix composition to adjust the ANI calibration coefficient value. This study, dealing with 118 litres, homogeneous drums of density less than 0,4 and composed of chlorinated and/or hydrogenated materials, leads to build abacus linking the y-ray peak areas to the ANI calibration coefficient. Validation assays ofthese abacus show a very good agreement between the corrected and true fissile masses for hydrogenated matrices (max. Relative standard deviation: 23 %) and quite good for chlorinated and hydrogenated matrices (58 %). The developed correction method improves the measured values. It may be extended to 0,45 density, heterogeneous drums
