Parasitic antennas are much lower in cost and complexity than conventional smart antennas. For this reason, they may be considered for use at the portable station. In this paper we study the capacity of a spacedivision-multiple-access (SDMA) system when n element switched parasitic antenna arrays (SPAA) are used for this purpose. As in [1], dynamic slot allocation (DSA) is used with a conventio...

Continued research into the development of III–V high-electron mobility transistors (HEMTs), specifically the minimization of the device gate length, has yielded the fastest performance reported for any three terminal devices to date. In addition, more recent research has begun to focus on reducing the parasitic device elements such as access resistance and gate fringing capacitance, which beco...

Reasonable flow channel designs play a significant role in improving the performance of proton exchange membrane fuel cells (PEMFC). The effect zigzag channels with three different numbers turns on PEMFC was investigated this paper. polarization curves, molar concentration oxygen and water, power density were analyzed, numerical results showed that overall significantly better than conventional...

Circuit-performance implications for double-gate MOSFET scaling in the sub-25 nm gate length regime are investigated. The optimal gate-to-source/drain overlap needed to maximize drive current is found to be different than that needed to minimize FO-4 inverter delay due to parasitic capacitances. It is concluded that the effective channel length must be slightly larger than the physical gate len...

In 2008, Novartis Animal Health developed a new class of anthelmintics, the amino-acetonitrile derivatives (AAD) of which monepantel is the most prominent compound. Monepantel was designed for the treatment of sheep against the parasitic nematode Haemonchus contortus. Because monepantel acts through a different mechanism, it is effective against nematodes that have acquired resistance to long-s...

Power dissipation of very large scale integrated circuits (VLSI) has emerged as a significant constraint on the semiconductor industry. For the dynamic power the voltage, capacitance and frequency are the major components of the power dissipation. In this paper, we propose a new power macromodeling technique for the power estimation of conventional metal-oxidesemiconductor (MOS) transistors. As...

Schistosomiasis is a parasitic flatworm disease that infects 200 million people worldwide. The drug praziquantel (PZQ) is the mainstay therapy but the target of this drug remains ambiguous. While PZQ paralyses and kills parasitic schistosomes, in free-living planarians PZQ caused an unusual axis duplication during regeneration to yield two-headed animals. Here, we show that PZQ activation of a ...

The 2-D resistive sensor array in the row-column fashion suffered from the crosstalk problem for parasitic parallel paths. Firstly, we proposed an Improved Isolated Drive Feedback Circuit with Compensation (IIDFCC) based on the voltage feedback method to suppress the crosstalk. In this method, a compensated resistor was specially used to reduce the crosstalk caused by the column multiplexer res...

Received April 27, 2012 Revised May 14, 2012 Accepted May 26, 2012 Application of symmetric double gate vertical metal oxide semiconductor field effect transistors (MOSFETs) is hindered by the parasitic overlap capacitance associated with their layout, which is considerably larger than for a lateral MOSFET on the same technology node. A simple process simulation has been developed to reduce the...

Introduction Organic thin-film transistors (TFT) have received considerable attention due to promises of low manufacturing costs, ease of processibility, and extendibility to flexible circuits. The feasibility of organic TFTs has largely been demonstrated with devices that use metal source and drain electrodes, such as gold and palladium. Such devices, when fabricated in the bottom-contact (BC)...
