The Effect of the Disintegration of Chemical Stratification on the Time-dependent Behavior of the Earth’s Mantle
A. Galsa, and M. Herein
Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing and homogenization of the dense D’’ on the time-dependent behavior of mantle convection. A ...

The present work aims to develop a blood pressure sensor using MEMS/NEMS technology. A normal blood pressure detector is used externally, but this work mainly aims for designing an implantable nanotube based sensor for continuous monitoring of blood pressure. The use of COMSOL Multiphysics 4.1 acts as a good platform to develop a nano tube based sensor design by using the MEMS module. The ...

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different thickness are placed on the cantilever, there is a corresponding change in the resonant frequency and the ...

In order to design an RF MEMS based device, it is beneficial to have information concerning mechanical behavior. For model verification purpose, solution offered by simulation software equipped with predefined physics application is one valuable way to provide initial reference. To avoid unwanted particular total strain in RF MEMS structures, a compensation layer can be utilized. When the number ...

Introduction: Power electronic converters such as those for High Energy Physics Experiments (HEPEs) must operate in thermally hostile environment. Heat generated by electronics components must be conveniently dissipated to ensure electrical performances and improve reliability. Due to the high power density, the presence of closed environments, and the requirement of non-thermal interaction with ...

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital capacitor. With a transmitting coil (coupling antenna), an electromagnetic field is generated which couples with ...
Lowering of the Interstitial Fluid Pressure as a Result of Tissue Compliance Changes during High Intensity Focused Ultrasound Exposure: Insights from a Numerical Model

Interstitial fluid pressure (IFP) is elevated in tumors. Owing to this elevated IFP, the interstitial fluid velocity (IFV) is negligible throughout the tumor but significant near the tumor margin. Any therapeutic strategy that can lower IFP will improve drug convection within the tumor and decrease convection of drugs from the tumor margin. High intensity focused ultrasound (HIFU) has been shown ...

Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not deliver satisfying results. This is why numerical modeling was applied to assess the thermal regime of the ...
