Повний текст джерелаThis thesis is devoted to the study of the localization of objects buried in underwater acoustic using array processing methods and acoustic waves. We have proposed a appropriate model, taking into account the water/sediment interface. The propagation modeling thus combines the reflected wave and the refracted wave to determine a new directional vector. The directional vector developed by acoustic scattering model is used in the MUSIC method instead of the classical plane wave model. This approach can estimate both of the object coordinates (angle and distance sensor-object) of known form, in near field or far field. We propose some fast algorithms without eigendecompostion. We combine DIRECT algorithm with spline interpolation to cope with the distorted antennas of many sensors, while maintaining a low computation time. To decorrelate the received signals, we firstly use a bilinear operator. We propose a method for the case of independent groups of correlated signals using the cumulants. Then we present a method using the cumulants matrix to eliminate Gaussian noise. But in practice, the noise is not always Gaussian or the characteristics are not always known. We develope two iterative methods to estimate the interspectral matrix of noise. The first algorithm is based on an optimization technique to extract iteratively the interspectral matrix of noise. The second algorithm uses the technique of maximum likelihood to estimate the signal parameters and the noise. Finally we test the proposed algorithms with experimental data. The results quality is very good

Повний текст джерелаWith the recent technological advances, the concept of smart communicating object has become a reality. Currently, two technical constraints reduce the deployment in our societies of these smart objects or wireless sensor networks : their size and consumption. The antenna constitutes one the most cumbersome parts of such an object. The miniaturization of the antenna by conventional methods leads to increased consumption. The aim of the thesis is to explore the potentials offered by the co-design of miniature antennas and radio frequency components in order to reduce the size of these devices and achieve a fabrication near to the integrated circuits. Thus, multifunction antennas have been achieved by co-designing the antenna with other features of the radio interface (filters, baluns, low noise amplifiers …)

Повний текст джерелаNanostructured materials with remarkable properties are being developed from manufactured nano-objects such as nanoparticles or nanofibers. Their production volume is growing rapidly given the potentialities in terms of application and economic gain. However, the risk of personnel involved in the production process requires the development of appropriate detection tools to characterize nano-objects. In this context two measurement techniques have been developed, evaluated and characterized. The first technique consists in sampling particles by filtration through a porous grid TEM (Transmission Electron Microscopy). Analysis by scanning or transmission electron microscopy coupled with EDX (Energy Dispersive X-ray) provides access to the morphology and chemical composition of particles. The first experiments showed that the device, easy to implement, allows a homogeneous and reproductible sampling. The collection efficiency of porous TEM grids was evaluated and compared to a numerical tool for quantitative results. The second technique named LIBS (Laser-Induced Breakdown Spectroscopy) provides access to the elemental chemical composition of an object (solid, liquid, gaseous or aerosol), in-situ and in real time, without sample preparation. The aim was to apply this technique to detect emissions of manufactured nano-objects. The LIBS technique has been optimized and implemented in a measurement campaign in an industrial laboratory (Arkema) producing carbon nanotubes (CNTs) and compared to other techniques for real-time measurements (counter, size speciation, …). Meanwhile, samples from TEM grids were made. By overlap with the results of sampling, the LIBS technique showed a potential to detect in real time CNTs bundle. Indeed, it has been shown that it is possible to detect CNTs bundle and to differentiate them from ambient air particles (carbon soot and other particles) through the amount of metal elements (aluminium and iron). Moreover, the sampling results showed emission of isolated NTC fiber in the case of accidental spillage of NTC powders

Повний текст джерелаFunctionalized iron oxide nanoparticles (NPs) have attracted an increasing interest as contrast agents for MRI. However, challenges remain to overcome: to optimize the functionalization of nanoparticles without affecting their magnetic properties while ensuring their biocompatibility and stealth in the human body, to prevent desorption of the grafted molecules under in vivo conditions, to ensure a small particle size distribution below 100 nm… In this context, we propose a novel strategy which involves the grafting, at the surface of NPs, of dendritic molecules (favoring the suspensions stability by steric hindrance and constituting a platform for the grafting of functional molecules) via a phosphonate coupling agent (allowing a direct grafting and a stronger binding) to develop innovative and competitive contrast agents. Thus, NPs with an average size of 10 nm were synthesized by two methods: co-precipitation and thermal decomposition. Three hydrophilic oligoethyleneglycol-based dendrons displaying a phosphonic acid at the focal point and three biocompatible chains (oligoethylene glycol) bearing functional groups such as COOH or NH2 were designed. The grafting conditions have been adapted according to the NPs and dendron natures. Numerous characterizations of the nanoparticles and their suspensions showed the preservation of the NPs magnetic and structural properties after the grafting step. Relaxivity measurements, in vivo tests and MRI measurements have shown the great potential of these dendronized nanoparticles for MRI

Повний текст джерелаMagnetic anomalies recorded outside bodies provide high quality information relative to buried structures. By using theoretical and experimental developments, this thesis aims to improve the characterization of the source inducing the magnetic anomaly. Firstly, some properties of three dimensional magnetic functions are presented, for example the presence of several maxima of the analytic signal operator (3D) is demonstrated. The Nabighian (1972) equation is generalized, which imply a new process to study potential method in two dimensions. These developments enable a new visualization of the anomaly in the complex field. The second approach is experimental. Synthetic cases are used to estimate the contribution of different configurations of magnetic data acquisitions at different altitudes to characterize the magnetic source. Theoretical and experimental developments are finally applied to two field examples: oceanic magnetic anomalies and archaeological magnetic prospection
