Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to ... Per saperne di più
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 ... Per saperne di più
Microrobotics has promising applications in microsurgery and microassembly. A challenge in these systems is interfacing with the robot. This project explores crawling robots that are powered and controlled through a global mechanical vibration field. By controlling the frequencies ... Per saperne di più
A ferrofluid contains nanoscale ferromagnetic particles suspended in a carrier liquid. It is used in some high-power acoustic speakers to cool the drive coil. The ferromagnetic particles far from the heat source are attracted by the drive coil’s magnetic field. As the fluid approaches ... Per saperne di più
This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained ... Per saperne di più
There is a considerable world-wide interest among lightning protection engineers and designers on the improvement of the standard procedures to assess the location of the most vulnerable places on complex structures to be struck by lightning flashes. This paper presents the ... Per saperne di più
Glow corona discharges are generated from tall objects during thunderstorms previous to a lightning strike. These discharges generate space charge which can hinder the development of subsequent discharges. In order to quantify the shielding effect of positive glow corona, a transient, ...

In this work, a MEMS low-g accelerometer with three sensitive directions is designed for health monitoring applications. The accelerometer may have different sensitivity in different axes. The proof-mass of the device is suspended by four serpentine springs, and the comb drive structure ... Per saperne di più
Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, ... Per saperne di più
