the current study aims to review the cross sectional variation in cash flow asymmetric timeliness and its effect on conditional conservatism. in this study, data from 120 firms in tehran stock exchange for the period spanning 1384- 1390 were examined. the regression model used in this research is panel data method with fixed effects approach. the most common measure of conditional conservatism ...

I Abstract In the process of designing an electric power supply system for an aircraft, parameters like low weight and low losses are important. Reliability, robustness and low cost are other important factors. In the Saab Gripen aircraft, the design of the primary power supply of the electric flight control system was updated by exchanging a switching transistor regulator to a magnetic amplifi...

In this paper, we introduce the new generation 3300V HiPak2 IGBT module (130x190)mm employing the recently developed TSPT+ IGBT with Enhanced Trench MOS technology and Field Charge Extraction (FCE) diode. The new chip-set enables IGBT modules with improved electrical performance in terms of low losses, good controllability, high robustness and soft diode recovery. Due to the lower losses and th...

To model the cells in our experiments, we utilized a modified detailed balance model, which included various forms of non-radiative recombination in addition to the radiative losses from the cell. This allows our model to be much more realistic than a traditional idealized detailed balance, where non-radiative losses are neglected. In addition, we simply input the measured short-circuit current...
