The complex wind effects around platform screen doors (PSDs) caused by train-induced piston effect and positive micropressure waves in subway station platforms are investigated. Numerical modeling of the field full-scale PSDs with real gaps under different inflow conditions is developed to analyze pressure distributions on corresponding recirculation regions frontal rear PSD areas computational...

In this paper, gate leakage current has been mitigated by the use of novel nanoscale MOSFET with Source/Drain-to-Gate Non-overlapped and high-k spacer structure for the first time. A compact analytical model has been developed to study the gate leakage behaviour of proposed MOSFET structure. The result obtained has found good agreement with the Sentaurus Simulation. Fringing gate electric field...

This paper presents two novel compensation circuits for leakage current and power supply noise (PSN) in phase locked loop (PLL) using a nanometer CMOS technology. The leakage compensation circuit reduces the leakage current of the charge pump circuit and the PSN compensation circuit decreases the effect of power supply variation on the output frequency of VCO. The PLL design is based on a 32nm ...

In this paper, two new circuits are proposed and compared to the existing techniques for the leakage power reduction of footed domino logic circuits. First proposed circuit employed one extra high-V pMOS t transistor between power supply and footer node. Second proposed circuit employed sleep transistors. Proposed circuits reduce both subthreshold and gate oxide leakage currents. Simulation is ...

This paper presents two novel compensation circuits for leakage current and power supply noise (PSN) in phase locked loop (PLL) using nanometer CMOS technology. The leakage compensation circuit reduces the leakage current of the charge pump circuit which becomes more serious problem due to the thin gate oxide and small threshold voltage in nanometer CMOS technology and the PSN compensation circ...

This paper investigates spectrum leakage influence on the performance of discrete Fourier transform (DFT) based phase difference measurement and proposes a novel method with spectrum leakage considered. In the proposed method, spectrum is firstly corrected by interpolation algorithm to remove the influence of short range leakage. To avoid negative frequency interference caused by the long range...

in this study cross section geometry and material of gasket in proton exchange membrane (pem) fuel cells have been investigated to achieve optimized fuel cell in terms of energy efficiency. the role of gaskets in fuel cells is sealing of gas flow channels and preventing from combination of them. in a pem stack, gasket with approved geometry that suffers more stress has better sealing. for this ...

The Fiat-Shamir transform is a well studied paradigm for removing interaction from publiccoin protocols. We investigate whether the resulting non-interactive zero-knowledge (NIZK) proof systems also exhibit non-malleability properties that have up to now only been studied for NIZK proof systems in the common reference string model: first, we formally define simulation soundness and a weak form ...

A retail store, especially a grocery store, has a high energy density due to decorative illumination and refrigerated cabinets. The purpose of this paper is to measure and analyse energy consumption of a grocery store and develop an energy demand model. The measurement revealed that energy consumption of refrigeration accounts for 60% of the total consumption and an air leakage has an effect on...
