in this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (qesc) have been simulated and investigated. optical path technic is used for simulation. the results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the qesc. simulation r...

A unified method for statistical anomaly detection in intrusion detection systems is theoretically introduced. It is based on estimating a dispersion measure of numerical or symbolic data on successive moving windows in time and finding the times when a relative change of the dispersion measure is significant. Appropriate dispersion measures, relative differences, moving windows, as well as tec...

an experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, ccl4/water, toluene /water + glycerol (25 % wt), toluene + ccl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. the effects of physical properties, mass transfer and column geometry on phase inversion have b...
