Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... 詳細を見る
The actuation system of the deformable mirror is one of the crucial components of an Adaptive Optics unit. One possible implementation comprehends a linear force motor and a capacitive sensor providing the feedback measure signal. Choosing a magnetic circuit that makes optimum use of the ... 詳細を見る
Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz ... 詳細を見る
The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... 詳細を見る
Fiber optic sensors can measure a large range of physical, chemical and environmental variables such as temperature, pressure, shape, position, chemical concentration, moisture, etc. Fiber optic sensors provide measurements in applications where the conventional electrical based sensors ... 詳細を見る
We model an ideal optical black hole device in COMSOL Multiphysics as an electromagnetic scattering problem. The device is illuminated with a Gaussian beam which is focused at a fixed position in horizontal direction (x0) and different positions in vertical direction (y0). The device is ... 詳細を見る
基于纸基微流控芯片(μPAD)的核酸提取和扩增反应需均匀稳定、快速响应的热源。半导体制冷器具有无需制冷剂和体积小等优点，可为纸基芯片提供便携式、低功耗分析平台。相较于其他传统核酸扩增与检测设备，μPAD可以借助内部纤维结构的毛细作用自驱动输送流体介质。并且，微尺度下纤维结构具备较高的比表面积，在原理上可改善常规比色、荧光等检测方法的检出限和精准度。然而，滤纸材料本征参数对试剂溶液动态扩散过程和反应结果影响很大，数值仿真模拟是μPAD性能分析和优化设计的重要途径。本文应用COMSOL®热电效应耦合模块和非等温流动耦合模块，获取芯片内部的温度场信息，评价μPAD温控系统设计 ... 詳細を見る
In this work we report on an investigation of the effect of the magnetic particles size on the effective macroscopic behavior of magnetorheological elastomers (MREs). MREs are a class of smart materials known for their tunable deformation. They are composite materials which consist of ... 詳細を見る
Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power ... 詳細を見る
The dielectric properties of heterogeneous media are of increasing interest as many applications exploit the usage of dielectric property detection in bio-imaging, scanning, microwave tomography and other electromagnetic applications. Using Laplace’s equation for non-integer dimensions, ... 詳細を見る
