Magnetic insertion of a cochlear implant can reduce intracochlear physical trauma by 50% compared to traditional manual insertion. The magnet attached to the tip of the cochlear implant electrode array must be detached and removed after surgery. This detachment process requires Joule ... En savoir plus
Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... En savoir plus
The present study aimed to determine the effect of nanofluid concentration, channel inclusion, flow rate, and heat flux, on the thermal effectiveness of Al2O3 nanofluid and 6061-T6 aluminum foam metal with 91% porosity and 40 linear pores per inch as components in a heat exchange system ...

The five year survival rate for malignant brain and central nervous system cancer was estimated at 35% between 2000 and 2015. Deep brain tumors can be unsuited for conventional surgical intervention. One minimally invasive treatment option is interstitial needle-based therapeutic ... En savoir plus
The author’s goal is to demonstrate the use of high porosity open-celled aluminum 6061-T6 foam as an effective heat sink with applications in electronics cooling. The experiment will demonstrate the effects of varying porosity, heat flux, and flow rate on the effectiveness of the heat ... En savoir plus
Temperature changes in the body have been recognized as an indicator of illness for centuries and localized temperature variations due to inflammatory or ischemic events are common in a great variety of diseases. In the case of cancerous breast tumors the increased cell growth rate ... En savoir plus
Increased demand for high power electronics has required increasingly more efficient thermal management techniques. Simple cold plates using tubes or channels are frequently used to cool high power components but restrictions on size, weight, and power have restricted their ... En savoir plus
储氢合金的PCT曲线和氢化动力学性能是描述合金储氢性能的重要标准，目前对合金的PCT曲线测试一般采用体积法，对合金氢化反应动力学的研究一般采用等容差压法。但在实际生产过程中，储氢合金通常是在恒定氢气流速的情况下工作的，所以研究合金在恒定氢气流速条件下的吸氢动力学性能很有必要。与实验相比，采用数值模拟预报合金的吸放氢性能节省了大量的时间和成本，具有突出优势。目前金属Pd及其合金被广泛应用于储氢及氢气纯化等领域，我们通过COMSOL软件建模，构建Pd吸氢热力学与动力学特性模型，选用传热、流体流动、域常微分等物理场模块建立了Pd在恒定氢气流速下吸氢动力学的计算模型 ...
