Efficiency Improvement of Emergency Lighting Circuit by Separately Excited One Transistor Inverter

Improvement of Waveform Efficiency Using a Compensation Circuit

In order to improve the efficiency(usable RF to total pulse) of a klystron modulator, a system using a solidstate compensation circuit has been developed. This system remarkably improves a flat-top and flatness of the output waveform of the modulator by means of waveform synthesis. This paper presents the design and specifications of the compensation circuit and the results of a preliminary tes...

Excited-State Parameters of One Intramolecular Cyclization by TD-DFT, CIS and ZINDO Methods

Using a time-dependent-density functional theory (TD-DFT), Configuration Interaction Singles (CIS) and Zerner’s Intermediate Neglect of Differential Overlap (ZINDO) methods, we have investigated the UV-Visible spectra of one new intramolecular cyclization at before and after intramolecular attack. All structures were optimized at the B3LYP/6-311++G** level while UV-Visible parameters were calcul...

LLP in Chain Inverter by using CMOS Circuit

This paper provide new low power solutions for Very Large Scale Integration (VLSI) designers. Especially, we focus on leakage power reduction. Although leakage power was negligible at 0.18μ technology and in nano scale technology, such as 0.07μ, leakage power is almost equal to dynamic power consumption. This paper presents heretofore unexplored methods for low-power VLSI design. In particular,...

Prediction of effect of fine particle removal on efficiency of a spiral circuit by size-by-size partition curves

Partition curves are widely used to determine the spiral separator efficiency. In this work, the partition curves were used in order to investigate the particle transportation to concentrate and tailing streams. Simulation of fine particle removal using the size-by-size partition curves showed that the recovery of gangue particles to concentrate can decrease 8.7%. It also showed that the recove...
