Excessive sediment deposition results to hydro-ecological problems particularly for shallow streams that experience significant point-source pollution. In recent times, models have been employed investigate transport in river systems. The aim of this research work is model Ele River using particle tracing methodology. governing equations fluid flow and movement were modelled COMSOL Multiphysics...

Available data and mathematical formulations concerning tritium transport in the FW/Divertor with tungsten and beryllium as plasma facing materials were implemented in the commercial code COMSOL Multiphysics. The goal is to develop a CAD-based multiphysics modeling capability so that FW/Divertor temperature and geometric features can be readily taken into consideration while tritium permeation ...

COMSOL Multiphysics software is used to describe the behavior of electrical resistivity several samples with rectangular shape typically in Montgomery method. The simulation data obtained using four isotropic conductors allowed us understand detail electric potential and field samples. results provide an analytical method which can substitute four-probe much more simplicity precision.

The impact of magnetic domains in flux concentrators is studied using the simulation software MuMax3. First, parameters are validated experimental results from force microscopy; second output benchmarked with one obtained Comsol Multiphysics. Finally, domain assessed, showing how micromagnetic effects can become relevant, if not dominant, when scaling gap between MFC and sensor.

Magnetophoresis of non-magnetic particles is the induced motion of non-magnetic particles suspended in magnetic media on the application of a magnetic field gradient. It involves many driving forces arising from different transport phenomena. Magnetophoresis can be used in special separation devices to separate colloidal particles based on their sizes. Multiphysics computational programs, such ...

Spinal Cord Stimulation (SCS) is a neurostimulation technique used to alleviate several kinds of chronic pain. Computer modeling of SCS is a powerful tool in predicting the effects of an electrical stimulus on nerve fiber activation. The UT-SCS, developed at the University of Twente, Enschede, The Netherlands, has provided useful insights on the mechanisms of SCS. Nevertheless, this software pr...

A finite-element method for calculating the illumination-dependence of absorption in three-dimensional nanostructures is presented based on the radio frequency module of the Comsol Multiphysics software package (Comsol AB). This method is capable of numerically determining the optical response and near-field distribution of subwavelength periodic structures as a function of illumination orienta...

Several parameter estimation problems (or ‘‘inverse’’ problems) such as those that occur in hydrology and geophysics are solved using partial differential equation (PDE)-based models of the physical system in question. Likewise, these problems are usually underdetermined due to the lack of enough data to constrain a unique solution. In this paper, we present a framework for the solution of unde...

The Voxel Imaging PET (VIP) Pathfinder project intends to show the advantages of using pixelated semiconductor technology for nuclear medicine applications to achieve an improved image reconstruction without efficiency loss. It proposes designs for Positron Emission Tomography (PET), Positron Emission Mammography (PEM) and Compton gamma camera detectors with a large number of signal channels (o...

Laser interstitial thermotherapy (LITT) is a cancer treatment technique in which laser fibers are introduced inside the tumor. While it destroys deep tumors, the LITT procedure allows minimizing the impact on adjacent healthy structures. Image guided focal photothermal ablation of low risk and low volume prostate cancer is feasible. However, dosimetry planning and conformation of the treated ar...
