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
A 1D phase change problem, known as Stefan’s problem, for which analytical solutions are available, is solved as a 2D problem using COMSOL Multiphysics. The PCM medium is semi-infinite, initially solid at its melting temperature Tm, and at t = 0, the wall temperature is raised to Tw > ... 詳細を見る
Variable capacitors between the fF and pF range are very interesting for high frequency applications like variable filters, resonators, etc. For radio astronomy applications variable capacitors, realized by electrostatically actuated, micromechanical Meanders-suspended bridges (MEMS) ... 詳細を見る
Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a ... 詳細を見る
Drug therapy of the posterior part of an eye is very challenging. Yet, in USA alone, there are almost 2 million people affected by age related macular degeneration. When designing a strategy for controlled-release drug delivery, it is important to take into account of physiology, ... 詳細を見る
Second-generation high-temperature superconducting (HTS) tapes are very promising superconductors for ac applications and numerical models are very important for predicting their performance, e.g. for computing the ac losses. These tapes are characterized by a very large aspect ratio: ... 詳細を見る
