We present a fast RTL leakage power simulator for datapaths described hierarchically in VHDL. Only the leafcells such as full adder, NAND gate etc., are characterized for leakage power. At the bit-slice level, exhaustive characterization can be performed in reasonable time. We observed that in the transient state, the leakage power is dependent on the previous input as well. This dependence is ...

With the technology process scaling, leakage power dissipation is becoming a growing number of percentage in total power dissipation. This study presents a new method in the gate-length biasing technique to achieve a cost-effective gate-length with a most benefit between leakage reduction and delay increasing. With the optimized gate-length, typical combinational and sequential circuits are rea...

to investigate the role of silicon (si) in alleviating the effects of salinity on quality and quantity of cut rose flowers ‘hot lady’cultivar was grown in hydroponic culture media. different levels of silicon (0, 50, 100 and 150 mg l-1) as si were mixed with 28 mm nacl (ec ≈3.8 ds m-1) levels, used in an rcbd experimental design.the results indicated that si in 50 and 100 mg l-1 had beneficial ...

A rotary vane expander has been developed to replace the throttling valve for improving the COP of transcritical CO2 refrigeration system. Due to the serious internal leakage, the expander efficiency is not satisfactory. This paper presents the theoretical and experimental investigation on the internal leakage in a rotary vane expander prototype. Firstly, the leakage flow rate through the inter...

Recently, with large-scale use of natural gas and massive constructions of gas pipelines, more and more public concern is focused on pipeline leakage. The leakage caused by holes on gas pipelines generates economic losses to gas companies and causes risks to the environment and sometimes accidents. In order to detect and locate pipeline rupture immediately, the leakage detection method plays a ...

This paper presents the effect of natural aging upon the performance of the polymeric insulat ion materials made from Epoxy resins, Polydimethylsiloxane (PDMS), and Rice husk ash compound. The sa mples of epoxy resin insulation material consist of Dig lycidyl Ether of Bisphenol A (DGEBA), Meta Phenylene Diamine (MPDA) as curing agent, and 325 mesh Rice Husk Ash (RHA) as filler, treated with var...

Background: Leakage is common in patients receiving home mechanical ventilation (HMV) via a face mask. Although pressure ventilators have partial compensatory capacity, excessive leakage can compromise the effectiveness of treatment. Home ventilators are equipped with built-in software which provides information on leakage. However, the values of leakage and their effects in routine clinical pr...

Flat-panel detectors using amorphous silicon p-i-n diodes have been developed for chest and therapeutic portal imaging. In radiation therapy, an imaging device is exposed to a high radiation dose. The radiation damage affects the leakage current of diode and may decrease the whole system performance. In this research, we have investigated the radiation damage to the leakage current of a-Si : H ...
