In sub-micron CMOS design, non-minimum length transistors offer the possibility of achieving excellent leakage control without the disadvantages of other known leakage control techniques. Preliminary analyses indicate that one can expect leakage reduction by a factor of at least 100 (and possibly orders of magnitude higher) with only modest increases in circuit area and switched capacitance. Th...

Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless). Despite making galvanic isolation, low frequency transformer increases size, cost and losses. On the other hand, transformerless PV systems increase the leakage current (common-mode c...

In this research, the behaviour of the differential equation governing volume flow through a pressure-controlled valve is examined with particular attention given to the rather troublesome transition between an open and closed valve. A closed-form solution for the time evolution of volume flow is given and used to derive an update for the volume flow. The result is a smooth, nearly alias free t...

This report shows the leakage power and the access latency of a novel asymmetric SRAM cell [1] using HSPICE simulation under different scenarios for FPGA architecture. Then, it shows that we are able to take advantage of the features of asymmetric cells and achieve 2X leakage power reduction for LUT-based FPGA.

The internal leakage has a great effect on the performance of a rotary compressor. In this paper a leakage model as a part of a complete simulation model is developed. The leakage model analyzes the oil/refrigerant mixture leakage flow through the roller radial clearance caused by the motion of roller relative to cylinder wall and the pressure difference and considers the effect of the motion o...

This paper presents a novel statistical characterization for accurate timing and a new probabilistic based analysis for estimating the leakage power in Partially-Depleted Silicon-OnInsulator (PD-SOI) circuits in BSIMSOI3.2 100nm technology. This paper shows that the accuracy of modeling the leakage current in PD-SOI CMOS circuits is improved by considering the interactions between the subthresh...

Lessening the leakage of surface water can reduce the waste of water resources and ground water pollution. To solve the problem that Mengxi River could not store water enduringly, geology investigation, theoretical analysis, experiment research, and numerical simulation analysis were carried out. Firstly, the seepage mathematical model was established based on unsaturated seepage theory; second...

Abstract : The cryptographic strength of an SP network depends crucially on the strength of its substitution boxes (S-boxes). In this paper we use the concept of information leakage to evaluate the strength of Sboxes and SP networks. We define a n equivalence class on n x n S-boxes that is invariant in information leakage. Simulation results for a 16x 16 SP network suggest that after a sufficie...

Fibrillar protein aggregates (amyloids) are involved in several common pathologies, e.g., Alzheimer's disease and type II diabetes. Accumulating evidence suggests that toxicity in amyloid-related diseases originates from the deposition of protein aggregates on the cell membrane, which results in bilayer disruption and cell leakage. The molecular mechanism of damage to the membrane, however, is ...
