This paper analyzes different types of coil systems to produce volumes of uniform magnetic field. Some types of coil system are presented in this paper such as Helmholtz, Merritt, and Ruben coil systems. In the study coil systems are intended to produce a magnetic flux density of 2µT in ... 詳細を見る

In all implantable medical devices, one main challenge is to assure no water penetrates in the electronic part of the system. To be able to transmit the electronic information from the inside of the device to the lead without any water infiltration, we used a complex part called feed ... 詳細を見る

A sphere sedimenting in a cylindrical tube filled with non-Newtonian fluids, including purely viscous and viscoelastic type, is of both practical and fundamental interest. To investigate the effects of shear-thinning and elasticity, four representative constitutive equations are adopted, ... 詳細を見る

In an earlier work we developed a finite element bidomain model of an aplysia abdominal ganglion in order to estimate the sensitivity of this contrast mechanism to changes in cell membrane conductance occurring during a gill-withdrawal reflex. We used our model to determine both current ... 詳細を見る

During the welding of tantalum with a ND: YAG pulsed laser, a deep and narrow cavity, called the keyhole, is formed. At the end of the process, surface tension forces provoke the collapse of the keyhole. For important interface deformations, gas bubbles can be trapped into the melting ... 詳細を見る

Insulin released by the beta-cells of pancreatic islets is the main regulator of glucose homeostasis, hence, insulin secretion models are of considerable interest for many possible applications. Building on our previous oxygen consumption and cell viability model for avascular islets of ... 詳細を見る

Multiphysics optimization of thermal-fluid systems is an emerging area of interest with application to the development of high performance cooling technologies for electronic systems. This paper builds on previous work focused on the development of a computational platform for numerical ... 詳細を見る

The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain ... 詳細を見る

Using COMSOL Multiphysics, studies were performed showing that thermomagnetic siphoning (TMS) is a sufficient manner of regulating the temperature of a bundle of current-carrying wires wrapped with a magnetorheological fluid (MRF) jacket. Because of Curie’s Law, the cooler MRF on the ... 詳細を見る

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... 詳細を見る
