Variable Capacitance And Pull-In Voltage Analysis Of Electrically Actuated Meander-Suspended Superconducting MEMS
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) ...

Thermal and Laminar-Fluidic Workbench for a metric Portion of a Gun
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 ... En savoir plus
A Virtual Pharmacokinetic Model Of A Human Eye
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, ... En savoir plus
Numerical Modeling Of Thin Superconducting Tapes
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: ... En savoir plus
FEM-Investigations Of Superconductor/Ferromagnet Heterostructures: A Compliance Test Between Various Models
In recent years, a number of numerical and finite-element-methods in particular - some implemented in COMSOL - have been developed to investigate various properties of superconducting materials. Following converse conclusions by different models regarding similar physical phenomena, the ... En savoir plus
A General Method for Solving Equations - The Dynamical Functional Particle Method
Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating ... En savoir plus
Robust and Reliability-based Design Optimization of Electromagnetic Actuators Using Heterogeneous Modeling with COMSOL Multiphysics and Dynamic Network Models
For an exemplary electromagnetic actuator used to drive a Braille printer, a design optimization was performed. The optimization involves stochastic variables and comprises nominal optimization, robustness analysis and robust design optimization. A heterogeneous model simulates the ... En savoir plus
Fluid Flow Simulations Using New CFD Module
COMSOL\'s new CFD Module has been tested for laminar and turbulent flows in simple geometries, with couple or segregated solver. These tests allow mesh sensitivities and comparison with analytical solutions. They also give a first idea of cpu time and RAM use for standard cases. In a ... En savoir plus
A Flexible Scheme For Numerical Homogenisation In Linear Elasticity
Musculoskeletal mineralised tissues (MMTs), like bone or tendon, are a prime example of naturally occuring, hierarchically structured material. They display a great variety in mechanical function but are all based on essentially the same building block: the mineralised collagen fibril ... En savoir plus
Wind Evaporation On Wetted Surfaces Under Uncertainty Conditions
Brine disposal from desalination plants placed in inland areas far from sea is an important problem. Evaporation ponds can be used for reducing the waste to solid state but they require huge amounts of land. Evaporation using arrays of wet surfaces can minimize the land requirements. One ...
