N recent years, the analog and mixed signal design, an innovative VLSI technology, is capable to satisfy the prime requirement for ubiquitous embedded system, which is playing a dominant role in flourishing dedicated VLSI based embedded technology [1].The dynamic reconfigurability is the important feature of many mixed signal devices. Due to unique feature, reconfigurability, this innovative te...

– We study the electron thermal transport in granular metals at large tunnel conductance between the grains, gT 1, and not too low a temperature, T > gTδ, where δ is the mean energy level spacing for a single grain. Taking into account the electron-electron interaction effects, we calculate the thermal conductivity and show that the Wiedemann-Franz law is violated for granular metals. We find t...

We measured the electrical conductivity of Mg0.81Fe0.19O magnesiowüstite, one of the important minerals comprising Earth's lower mantle, at high pressures up to 135 GPa and 300 K in a diamond-anvil cell (DAC). The results demonstrate that the electrical conductivity increases with increasing pressure to about 60 GPa and exhibits anomalous behavior at higher pressures; it conversely decreases to...

Electrically conductive polymer composites filled with carbon black can exhibit the mechanical behavior of a polymer and metallic electrical conductivity. Unfortunately, excessive amounts of carbon black can produce brittle films and too little carbon black can result in low conductivity. Composite conductivity can be dramatically improved by using latex as the matrix starting material. Latex p...

To address the trade-off between strength and electrical conductivity, we propose a strategy: introducing precipitated particles into a structure composed of deformation twins. A Cu-0.3%Zr alloy was designed to verify our strategy. Zirconium was dissolved into a copper matrix by solution treatment prior to cryorolling and precipitated in the form of Cu5Zr from copper matrix via a subsequent agi...

The purpose of this work was to determine the influence of mechanical and electrical treatment on the electrical conductivity of aqueous solutions. Solutions were treated mechanically by iteration of two steps: 1:100 dilution and vigorous shaking. These two processes were repeated until extremely dilute solutions were obtained. For electrical treatment the solutions were exposed to strong elect...

aquaculture is among the oldest occupations of human being. over the past quarter of century, the aquaculture industry has grown rapidly. the effect of water containing sodium sulfate on long term compressive strength of concrete of fishing ponds and channels is investigated in this paper. aim of this paper was to analyze the strength of concrete channels and of aquaculture which are in direct ...

BACKGROUND Few finite element models (FEM) have been developed to describe the electric field, specific absorption rate (SAR), and the temperature distribution surrounding hepatic radiofrequency ablation probes. To date, a coupled finite element model that accounts for the temperature-dependent electrical conductivity changes has not been developed for ablation type devices. While it is widely ...
