DETECTION AND LOCATION OF SURFACE DAMAGE USING THIRD-ORDER COMBINED HARMONIC WAVES GENERATED BY NON-COLLINEAR ULTRASONIC WAVES MIXING

Detection and Location of Surface Damage Using Third-Order Combined Harmonic Waves Generated by Non-Collinear Ultrasonic Waves Mixing

Metals which are widely used in many types of industries are usually subjected to fatigue and surface corrosion.There is a demand to detect the surface damage caused by fatigue and corrosion at an early PALAIS DES THES stage to ensure the structural integrity.In this paper, a novel nonlinear ultrasonic technique based on the measure of third-order

Sparse camera volumetric video applications. A comparison of visual fidelity, user experience, and adaptability

IntroductionVolumetric video production in commercial studios is predominantly produced using a multi-view stereo process that relies on a high two-digit number of cameras to capture a scene.Due to the hardware requirements and associated processing costs, this workflow is resource-intensive and expensive, making it unattainable for creators and re

Towards mastery of complex visuo-motor transformations

In this paper we review and integrate a set of findings on learning the transformation of a sliding first-order lever, a type of tool with a prominent role in minimal access surgery.Its kinematic transformation is characterized by the so-called fulcrum effect, the inversion of the movement direction of the tip of the lever relative to that of the h
