Continuous welded turnouts are important for CWR track through the railway station. According to equivalent resistance and non-linear theories and the principle of force diagram, a new method of theoretical calculation for continuous welded turnouts was developed. The continuous welded turnouts designed and installed according to the new theory behaved fairly well. The data collected on sites b...

In this work, we show a general approach for inhomogeneous composite thermoelectric systems, and as an illustrative case, we consider a dual thermoelectric cooler. This composite cooler consists of two thermoelectric modules (TEMs) connected thermally in parallel and electrically in series. Each TEM has different thermoelectric (TE) properties, namely thermal conductance, electrical resistance ...

omentin-1 is a novel adipokine that is predominantly secreted by visceral adipose tissue. circulating levels of omentin-1 is inversely related to obesity. there is limited information about the effect of exercise training on serum omentin-1 concentration. the aim of this study was to investigate the effect of four weeks of progressive resistance training on serum omentin-1 levels. 16 male wiste...

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

the pyroxene composition of basaltic rocks from the coloured series and exotic blocks in the neyriz area are discussed. comparison has been made with equivalent rocks from oman. the clinopyroxene compositions are in cognation with trace and rare-earth element analyses which definately confirm the occurrence of three different trends in basic lavas: i-depleted tholeiite, 2-transitional basalt, 3...

This letter presents the impact of source/drain series resistance on the matching of bulk NMOS and PMOS fieldeffect transistor current over the 5–300 K temperature range. A new method to extract series resistance is introduced, and we show experimentally that current variations, considering series resistance, increase as temperature decreases. Moreover, we propose a new approach to calculate th...

One of the important parameters, that commonly affect solar cell performances, is the series resistance. Such effect becomes more pronounced when working under higher illumination intensities due to higher generated photocurrents. Therefore, it is necessary to predict series resistance effects under such conditions. To know more about the series resistance effect and its interpretation, InGaP b...
