Full textThe purpose of this thesis is to propose ultrasonic signal processing methods in order to improve the transitory flow velocity non-intrusive detection through pipes, in complex measurement conditions. By complex measurement conditions, we refer to high or very low flow rates and also to transitory or turbulent flows. Usually, the flow velocity can be non-intrusive estimated, using ultrasonic flow meters based on transit time estimation. Conventional transit time flowmeters are based on the alternating emission of single-frequency acoustic pulses (ie, narrow-band acoustic pulses) and the calculation of the absolute difference between flight times in the direction of flow (direct) and in the opposite direction (reverse). The fluid velocity (and the flow rate), or rather the precision of estimation of these quantities, rest mainly on the estimation of this difference. The sensitive part of this technique is the choice of the threshold (assuming that the received signal is not affected by other phenomena such as echoes, excessive attenuation or Doppler effects) determined mainly empirically: above 50% or 80% of the maximum expected value of the signal. Techniques for reducing measurement errors are quite conceivable and provide acceptable accuracy under almost ideal measurement conditions. However, apart from the case with idealized measurement conditions, there are several scenarios where current techniques are deficient: sensor misalignment, excessive flow velocity which leads to the “flow blow” effect, two-phase flow and / or the presence of the Doppler effect. These facts, presented in the second chapter of the manuscript, led us to consider, within the framework of this thesis, research axes whose common objective are to provide the signal processing tools capable of lifting the operational locks. Thus, the signal processing principles considered to meet this objective are: the principle of wide-band signals which gives the signal processing system a finer resolution and better robustness to disturbances; the concept of compressing sensing in order to reconstruct the missing samples due to interference at the reception point; the principle of beamforming and the principle of multi-paths which makes it possible to evaluate the velocity profile in a pipe section

Full textThe recent progresses of the digital high speed cameras allows us to analyze very fast phenomena, such as cracks propagations, vibrations or impacts loading. These cameras give us a single frame of each time of experimental process. Optical methods in mechanics are widely used by researchers and engineers. The values of the quantities we are looking for are contained in the demodulated phase of the fringe pattern. Usually, in static, the phase extraction is performed by a phase shifting technique using several fringe patterns. But, this approach is unavailable for studies in dynamics. In this case, we have access to only one image for a given mechanical state. So we must extract the information from a single fringes pattern. We present two techniques of phase demodulation from a single real fringe pattern using the correlation technique. The behavior and the performances of both algorithms are presented with the help of examples

Full textIn the sea, the acoustic detection of other battle engines is done by detecting mostly stationary signals. However, new types of detection systems are being developed, and are able to detect and to analyze transient signals. Therefore, the industrial conception process needs to be improved, so that the underwater vehicles transient noises can be taken in account. In order to do so, the mechanism of vibroacoustic transfer of transient sources of submerged structures has to be understood. The object of this thesis is then the study of the mechanism of vibration transfer and acoustic radiation of those structures when they are excited by transient sources. The shell radiation in the water, the wave diffraction by circumferential stiffeners and the resonant behavior of internal substructures are analyzed. The first chapter presents the bibliographical study of three themes: the study of transient phenomenon of submerged structures, the influence of heavy fluid coupling on vibroacoustic behavior of plates, and the different calculation methods in transient vibroacoustics. In the second chapter, we study the transient response of a submerged infinite plate excited by an impulsively point force. First, the calculations are done in the wavenumber-frequency domain. Then the spatio-temporal responses are obtained using inverse Fourier transforms. The discretization of wavenumber and frequency domains and the damping model are studied. The analysis of frequency and time responses of the plate vibration and the radiated pressure enable us to observe the influence of heavy fluid coupling. Besides the Mindlin-Timoshenko plate model is also used and the effect of rotation inertia and shear stress are studied. In the third chapter, these numerical results are confronted to experimental data, obtained experimentally. The studied structure is a rectangular plate lying on the surface of a water tank. Two different excitations are used: an impact hammer and the free fall of a steel ball. The study of the correlation between numerical and experimental results showed that some phenomena are observed in both cases. The influence of stiffeners on the acoustic radiation is the theme of the fourth chapter. An infinite plate which is periodically stiffened through one direction is considered. The effect of Bloch-Floquet waves on time response is studied. Numerical results are compared to measurements data obtained on an industrial submerged structure. In the fifth chapter, the effect of internal structures is analyzed by modelling an infinite plate coupled to a resonant system made of a beam and a rectangular finite plate. The inertance coupling method is used to obtain the coupling forces between the different substructures. Influence of inertance difference between the substructures is illustrated by the time signals

Full textObservations of atmospheric and ocean surface dynamics can be performed via radar remote sensing. The usual approach consists, in both cases, in numerically calculating the Doppler spectrum of the received temporal echoes using a discrete Fourier transform. Although satisfactory for most applications, this method is not suitable for observations of transient phenomena due to being shorter than the integration time required for radar observations. We use an alternative technique based on an autoregressive representation of the radar time series combined with the maximum entropy method. This approach is applied to coastal radar measurements of surface currents in the high frequency band as well as to L-band radar measurements of wind in the lower atmosphere. For both cases, through numerical simulations and case studies, we compare our approach with others that use different instruments. We show that for short integration times, where conventional methods fail, our proposed approach leads to reliable estimates of geophysical quantities (ocean currents and wind speeds)
Nguyen, Hong-Minh. "Une stratégie d'identification robuste pour la localisation et la rupture." Phd thesis, École normale supérieure de Cachan - ENS Cachan, 2006. http://tel.archives-ouvertes.fr/tel-00140895.
Full textLes difficultés rencontrées dans ces cas résident dans la non-linéarité et le caractère instable du problème de minimisation sous contraintes non linéaires auquel la formulation nous amène. Une extension de la méthode LATIN aux problèmes mal posés a été proposée et développée afin de permettre la résolution itérative de ce type de problèmes d'optimisation. La résolution de ces derniers fait appel à une méthode de traitement robuste issue du contrôle optimal et basée sur l'équation de Riccati.
Une fois ces difficultés résolues et dans les cas simples unidimensionnels traités pour le moment, la stratégie d'identification proposée s'avère très robuste face aux perturbations des mesures même dans le cas très sévère de la localisation et de la rupture.
