  • A New Hybrid Table/Analytical Approach to MOSFET Modeling for Cryogenic Technologies

    In this paper, a new simple and accurate hybrid table/analytical model of the MOSFET drain current based on the interpolation of table parameters is proposed. This new hybrid table model has an accuracy similar to the pure table models but requires no complex parameter extraction. The drain current in the hybrid model is calculated as the product of the analytical model current and the correction factor approximated by two-dimensional series.

  • Experimental investiganios of deformation and fracture of plates at repeated impact loading.

    The paper describes the experimental complex designed for impact testing of thin-walled structural elements, as well as the results of experiments on one-time and repeated impact deformation of square plates. The experimental complex uses an induction-dynamic motor as loading device, which allows to conduct repeated impact loading. Impact test were done on thin square steel hinged plates. The time variation of strain components were determined by use of strain gauges and analog-digital converter connected to PC. Experiments on repeated impact loading show that averaged number of cycles to plate's punching is equal to 79 cycles, which coincides to low-cycle area.

  • Hardware to store large data volumes

    One of the problems when storing large amounts of data is a rational choice of media. In this paper we evaluated the possibility of using magnetic tape, CD, DVD, Blu-ray discs, hard disk drives, drives to flash memory (SSD) for storage of large volumes of data with respect to reliability, performance,.cost and high-speed storage. The analysis showed that solid state drives can be used in case of the need for ultra-fast access to live data. The hard disk drive can be used as primary storage devices for storing operational data. DVD and Blu-ray library can be used for archival storage medium volumes (tens of terabytes). Tape libraries can be used to store very large volumes of data (terabytes or more). The lowest cost of storing 1 GB of data is $ 0.03 when you use tape libraries. The most expensive storage 1 GB solid state drive ($ 0.85).
