This paper describes how to achieve a desired speedup by careful selection of appropriate algorithms for parallelization. Our target simulation is the Total Airport and Airspace Model (TAAM), a worldwide standard for aviation analysis. TAAM is designed as a sequential program, and we have increased its speed by incorporating multithreaded algorithms with minimal changes to the underlying simula...

a bstract background: non‑medical utilization of pre‑implantation genetic diagnosis (pgd), like sex selection, is increasing, therefore it is necessary to follow‑up the health and outcome of fertilization and newborn’s birth followed pgd. the aim of this study was to evaluate the outcome of fertilization after sex selection by pgd and the relation between the age of parents and the outcome of f...

In this paper, we investigate several algorithms that construct the input for the synthesis filter in the CELP coder, we present them under the same formalism, and we compare their performances. We model the excitation vector by a linear combination of K signals, which are issued from K codebooks and multiplied by K associated gains. We demonstrate that this generalized form incorporates severa...

In this paper an ultrawideband low noise amplifier is proposed. The structure is based on 0.18 μm CMOS technology. The design is based on the current reusing structure to provide the wide band characteristics. A wideband flat gain (S21) about 20dB is achieved, stability of the structure over the whole desired frequency range is provided. Due to careful selection of the elements and biasing cond...

A model for the terahertz optical asymmetric demultiplexer ( ) TOAD is presented, and its performance is assessed. A numerical ( ) model of a semiconductor laser amplifier SLA used as a nonlinear element is also gï en. Results of SLA carrier density, switching window, pulse switching, and a comparison of phase modulation and power gain for a frame rate higher than the recombination are presente...

In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...
