Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... En savoir plus

The knowledge of the acoustical transfer paths in active noise control systems is very important for the performance of the system. Unfortunately, simulation is challenging since even simple configurations require comprehensive experience in physics and modeling. Two test setups were ... En savoir plus

Manufacture of complex micro-scale parts such as biomedical devices and micro tools that require an excellent surface finish has required non-conventional manufacturing processes such as pulsed electrochemical machining (PECM). Additional reverse polarity pulses make the PECM bipolar ... En savoir plus

Single turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting field shaper and an internal conducting tube ... En savoir plus

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... En savoir plus

Introduction: Chronic arterial hypertension (HTN) is a pathological condition characterized by prolonged high level of arterial blood pressure causing major damages to several human body apparata. Renal sympathetic denervation (RDN) has been found to effectively reduce systemic blood ... En savoir plus

COMSOL Multiphysics software was used to simulate the working of the electrode. The piezoelectric device physics was used to evaluate the displacement created and the potential generated due to piezoelectricity of PDMS. The potential created due to the flow of bio-signals between neurons ... En savoir plus

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal ... En savoir plus

Vacuum window is required in the millimeter wave transmission line in ITER*. It is to be designed to minimize the microwave reflection while keeping a robust and safe approach to meet the requirements. We have studied transmission characteristics of various dielectric materials over D ... En savoir plus

COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... En savoir plus
