This paper presents a modal Udwadia-Kalaba formulation based on complex modal analysis. This alternative formulation is developed in the general case of vibro-acoustic systems with an internal cavity. In a similar manner to the original formulation, the global response of a constrained multibody system is expressed as a sum of its unconstrained res...

Oxygenators, alarm devices, and footsteps are some of the most common sound sources in a hospital. Detecting them has scientific value for environmental psychology but comes with challenges of its own: namely, privacy preservation and limited labeled data. In this paper, we address these two challenges via a combination of edge computing and cloud ...

Semi-anechoic rooms are used for the acoustic characterisation of noise sources. They involve heavy infrastructures and thick absorbent lining. The aim of this work is to demonstrate a less expensive alternative by complementing a thin passive coating with an active technology. Previous work has achieved the active reduction of the pressure scatter...

This thesis focuses on material adhesion, which is often crucial to the reliability of coating technologies. More precisely, the adhesion quality of a polyvinyl chloride film to an aluminum substrate is evaluated by Laser-Ultrasonics. Indeed, this non-contact and non-destructive method allows to excite surface acoustic waves (SAW) in layer-on-subst...

L’impact des jets sur diverses surfaces est au cœur de nombreuses problématiques, notamment en termes de refroidissement et de nettoyage de surface. Cette thèse se penche sur deux aspects différents de ce sujet pour des jets sub-millimétriques, peu étudiés dans la littérature. Dans un premier temps, nous explorons le ressaut hydraulique circulaire ...

This paper presents a new design of CADEL, a cable-driven elbow-assisting device, with light weighting and control improvements. The new device design is appropriate to be more portable and user-oriented solution, presenting additional facilities with respect to the original design. One of potential benefits of improved portability can be envisaged...

Surface acoustic waves (SAWs) convey energy at subwavelength depths along surfaces. Using interdigital transducers (IDTs) and opto-acousto-optic transducers (OAOTs), researchers have harnessed coherent SAWs with nanosecond periods and micrometer localization depth for various applications. However, the utilization of cutting-edge OAOTs produced thr...

One of the major challenges in the science of maxillofacial radiology imaging is the various artifacts created in images taken by cone beam computed tomography (CBCT) imaging systems. Among these artifacts, motion artifact, which is created by the patient, has adverse effects on image quality. In this paper, according to the conditions and limitati...

The lack of specialized personnel and assistive technology to assist in rehabilitation therapies is one of the challenges facing the health sector today, and it is projected to increase. For researchers and engineers, it represents an opportunity to innovate and develop devices that improve and optimize rehabilitation services for the benefit of so...

Many objective measurements have been proposed to evaluate sound reproduction, but it is often difficult to link measured differences with the differences perceived by listeners. In the literature, the best correlations with perception were obtained for measures involving an auditory model. The present study investigated simpler measurements to hig...
