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...

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...

The γ−ray burst GB970508 was observed simultaneously by the Gamma Ray Burst Monitor (GRBM) and one of the X−ray Wide Field Cameras (WFC) aboard BeppoSAX. The latter provided a position within 1.9 radius. A series of follow-up observations with the Narrow Field Intruments (NFI) was then performed in a period from ∼ 6 hours to 6 days after the main event. A previously unknown source, which we ass...

In view of the uneven artificial sowing, low sowing, as well as the fact that the existing seeders cannot meet the sowing requirements of Pteris vittata, this paper designed an automatic plug seeder by using the method of spraying and sowing after mixing spores and water. In order to obtain the optimum working parameters of the seeder, response surface method (RSM) was employed to desi...

In this paper a new approach for transmission pricing is presented. The main idea is voltage angle allocation, i.e. determining the contribution of each contract on the voltage angle of each bus. DC power flow is used to compute a primary solution for angle decomposition. To consider the impacts of system non-linearity on angle decomposition, the primary solution is corrected in different itera...
