There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD . A virtual pharmacokinetic 3D model of the human eye is built to address this problem, using COMSOL Multiphysics® software, based on the Finite ...

Nano patterning for chip manufacturing has reached its limitation with 193i lithography standard process. Directed Self Assembly (DSA) of Block Co-Polymers (BCP) is envisaged as an alternative complementary technique that can reduce critical dimension and pitch with high throughput and limited cost . For contact layers that require patterning of cylinders with diameter of tens nanometers, DSA ...

Dental restorations can be made by different materials bonded together, which grant good mechanical resistance and aesthetic at the same time. In order to evaluate the behavior of dental restorations in the oral environment, a test, called thermocycler, is used, which simulates the temperature changes and the chemical environment of the mouth. The objective of this work is to evaluate thermal ...

This paper reports the simulation of micro-electro-mechanical system (MEMS) cleanroom for the purpose of determining the effect of particulate contaminants on the static stress response of cantilever type MEMS devices, such as high precision MEMS pressure sensor. The contaminant presence has been qualitatively verified through computational fluid dynamic simulation of the clean room in COMSOL ...
所谓近场声学，是相对于远场声学而言。传统的声学理论，通常只研究远离光源或者远离物体的声场分布，一般统称为远场声学。远场声学在原理上存在着一个远场衍射极限，限制了利用远场光学原理进行显微和其它光学应用时的最小分辨尺寸和最小标记尺寸。而近场声学则研究距离光源或物体一个波长范围内的光场分布。在近场声学研究领域，远场衍射极限被打破，分辨率极限在原理上不再受到任何限制，可以无限地小，从而基于近场声学原理可以提高显微成像与其它光学应用时的光学分辨率。 声学超材料自问世之日起就受到了国内外科学家们的广泛追捧，在很多领域都可以看到其踪迹，以声子晶体为代表的声超材料具有很多天然材料所不具备的声学特性，为声学信号处理带来了很多创新的思路和途径。 声超材料的突出特点在于采用尺寸远小于入射波长的人工结构构建出等效参数，利用等效参数实现“小尺寸结构调控大尺寸波长”的目的。 ...

Landfill is currently the most dominating method to dispose wastes, which are caused by the lives of residents and constructions of cities and towns. Because of large amounts of organic substances in landfills, they will undergo continuous microbial degradation, which generates a lot of landfill gas. The gas consists mainly of CH4, CO2, O2 and N2, and it is also a promising source of renewable ...

The thermocapillary effect is widely used in microfluidic applications for sensing and actuation and can also be used to generate rigid-body motion. Furthermore, it is possible to cast Marangoni flows to achieve controllable rigid-body motion in 3D space. To this effect, here we present the basics of a simulation technique to analyze 6-DOF time-dependent rigid-body motion of such a microswimmer ...

The vibration behavior of carbon fiber reinforced composites (CFRP) specimens with impact damage is presented in order to evaluate if an before/after modal analysis can be used as a non-destructive testing method to detect delaminations. The impact damage is modeled by decreasing the stiffness in the described area of delamination. As detailed experimental data exists for the modeled structure, ...

The paper on EMC Simulation Analysis of Enclosures demonstrates a simulation method to analyze the shielding effectiveness of enclosures. From the early development stage on it is possible to analyze the effect of electromagnetic waves on shielding panels. Different types of openings have been virtually measured in a test chamber. Therefore the full Maxwell equations have been solved in the ...

We demonstrate a new method of finding stationary solutions to nonlinear equations using a dynamical damped oscillatory model to minimize an energy functional. The method can be used for diverse physical problems and is here demonstrated both for finding stationary solutions to the heat equation and to the nonlinear Schrödinger equation. The method is very general and can handle equations with ...
