Drop test simulation is one of the important tool used for the impact behaviour study of electronic components. It identifies the flaws in design. The reliability and performance of electronic consoles after the drop is a major concern. Devices are expected to continue functioning after suffering a drop. The model is allowed to fall freely due to gravity load application. Drop test standard ...

Previous studies proposed using bipolar radiofrequency ablation across two catheters placed on opposing surfaces of the ventricular wall to create transmural lesions. 2D and 3D models were built and solved with COMSOL Multiphysics software. With these models, it was possible to study the temperature distribution and lesion geometry (Figure), to compare the potential of two ways of applying ...
Extending Engineering Simulations to Scientists: Food Safety and Quality Prediction Using COMSOL Multiphysics® and LiveLink™ for Excel®

Electromagnetic radiofrequency (RF) sources are widely used to heat up cutaneous and subcutaneous tissues. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells; however, it is commonly regarded as a homogeneous fat layer in computational models. In the present study the objective is to assess the effect of the ...

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the arterial geometry plays an important role in determining the localized blood flow information. Thus hemodynamic ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

The delivery of chemotherapy for cancer into the central nervous system, in particular the brain, remains a challenge. This results in brain metastases commonly being a cause of death from cancer. Here, we look at the environment of the blood-brain barrier. Then, we explore two proteins (breast cancer resistance protein and p-glycoprotein) that may inhibit the transport of medications (erlotinib ...

The mathematical modeling of the diffusion and reaction of toxic compounds in mammalian cells is tough task due to their very complex geometry. The heterogeneity of the cell, particularly the cytoplasm, and the variation of the cellular architecture, greatly affects the behavior of these toxic compounds. Homogenization techniques have been implemented for the numerical treatment of the model. ...
Simulation of Chemotractant Gradients in Microfluidic Channels to Study Cell Migration Mechanism in Silico

Cell migration of endothelial cells along gradients is an important process in vivo and an interesting target for cancer therapeutics. Microfluidics offer very powerful tools to study such migration processes in detail in the lab. In this study, we describe a model to simulate molecular gradients in a diffusion based microfluidic gradient generator and how a cell senses these gradients via cell ...

Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological examination with MRI/CT scans which is costly and time consuming. Microwave Tomography (MWT) is proposed as a ...
