Повний текст джерелаAs the studies on shallow-water acoustics became an active field again, this dissertationfocuses on studying the separation and detection of raypaths in the context of shallowwaterocean acoustic tomography. As a first step of our work, we have given a briefreview on the existing array processing techniques in underwater acoustics so as to findthe difficulties still faced by these methods. Consequently, we made a conclusion thatit is still necessary to improve the separation resolution in order to provide more usefulinformation for the inverse step of ocean acoustic tomography. Thus, a survey on highresolutionmethod is provided to discover the technique which can be extended to separatethe raypaths in our application background. Finally, we proposed a high-resolutionmethod called smoothing-MUSICAL (MUSIC Actif Large band), which combines thespatial-frequency smoothing with MUSICAL algorithm, for efficient separation of coherentor fully correlated raypaths. However, this method is based on the prior knowledgeof the number of raypaths. Thus, we introduce an exponential fitting test (EFT)using short-length samples to determine the number of raypaths. These two methodsare both applied to synthetic data and real data acquired in a tank at small scale. Theirperformances are compared with the relevant conventional methods respectively

Повний текст джерелаEmulsions are formed when two non-miscible liquids are mixed. The best known are oil-water emulsions (eg cosmetic cream, mayonnaise), but it also is possible to make other types of emulsions such oil-oil or water-water (W/W) emulsions. To obtain the latter, two aqueous solutions of incompatible polymers are mixed. In order to use these kinds of emulsions for instance in the food industry, one needs to stabilize them. Unlike oil-water emulsions, the use of molecular surfactants to stabilize W/W emulsions is not possible, because they have a very low interfacial tension and a broad interface.Stabilization of W/W emulsions is well studied in the literature, mainly by gelling of the continuous phase, or by using particles as interface stabilizers, so-called Pickering effect. In this study, the objective was to stabilize W/W emulsions by polymers that have some affinity with both phases and locate at the interface. For that purpose, we used a model emulsion made of PEO (P) and dextran (D) as incompatible polymers. It was found that out of 16 polymers tested, mainly polysaccharides, only three show a stabilizing effect of emulsions: chitosan, diethylaminoethyl dextran (DEAED) and propylene glycol alginate (PGA). Interactions of these polymers with PEO and dextran were investigated with light scattering and the microstructures was studied by confocal laser scanning microscopy. The effects of pH, ionic strength, interfacial tension and polymer concentration were studied to understand mechanism of stabilisation. Emulsions were characterized by different techniques and especially by means of LUMisizer©, LUMiReader©,to follow turbidity as a function of time, and rheology. In order to understand why some polymers were able to stabilize water-in-water emulsions and other cannot, chemical modifications of chitosan were carried out to vary the amount of charges and hydrophobic groups. Subsequently, the effect of these modifications on the stability of the emulsions was investigated

Повний текст джерелаThe development of decentralized and specific sanitation system is an issue that concerns both the improvement of sanitary conditions in the poorest area of the world and the development of renewable sources of nutrients for agriculture. This study aims to provide some elements about a treatment line including crystallization and membrane separation for the treatment and valorization of urine. Crystallization allows to recover phosphorus and part of nitrogen contained in urine. Membrane separation is used in order to remove bacteria and viruses from urine. To check the potentialities of these processes some tests were performed at labscale with synthetic and real human urines.It was shown that the struvite crystallization by magnesium addition with a ratio Mg:P=1,3:1 allows recovering most of the phosphorus from urine with a very rapid kinetics (about 20s). Influence of mixing conditions, urine storage, organic matter and initial crystals in urine was studied in batch and continuous reactor. Ultrafiltrations of different pretreated urines (no pretreatment, stored urine, stored and crystallized urine) were performed with PES, PAN and PVDF membranes. Mechanisms responsible for an important flux decline during urine flitration were studied. Specific influence of particular, colloidal and soluble fraction on the flux decline was also evidenced. On these basis different possible treatment lines of urines are proposed and discussed

Повний текст джерелаWe present in this thesis a study of the hydrodynamic behavior of nanoparticles suspended in a ferrofluid and subjected to a magnetic field gradient. The goal is to characterize the magnetic separation of a colloidal suspension in a project to design a water treatment system HGMS (High Gradient Magnetic Separation) that can also have other applications. We develop a mathematical model that describes the Lagrangian tracking of nanoparticles in a carrier fluid. It is based on the Fokker- Planck and Langevin descriptions while taking account of magnetic and hydrodynamic interactions between particles. The model also takes into account the geometry of the formed aggregates. From the numerical simulation, we find that the separation time depends strongly on the size and length of the aggregates formed during the separation process. The study of the kinetics of aggregation shows the existence of a regime with dynamic scaling. In the irreversible aggregation linear chains of particles are formed and their average size changes over time with a scaling law with a low power. The variation exponent of the average size of chains is consistent with the Smoluchowski coagulation equation with a homogeneous kernel. Using the asymptotic, long-time behavior, of a solution of Smoluchowski equations we highlight a characteristic time of aggregation and we show that this time is a similarity variable on which depend the separation time. We also show that the scaling law is still valid for nanoparticles in a Poiseuille flow and the average size follows a power law as a function of Reynolds number
