To meet consumer and legislation requirements, various technologies have been used worldwide to achieve optimal fuel consumption and to reduce greenhouse gas emissions. One of the proposed technologies is cylinder deactivation using various methods, including, injectors cutting off, closing the intake and exhaust valves and crankshaft decoupling. In this paper, a GT-Power model is created to in...
Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...

We propose and demonstrate an architecture that achieves passive coherent combination of two femtosecond fiber chirped-pulse amplifiers. The setup consists in the use of a well-balanced amplifying Sagnac interferometer. The experiment shows that the temporal, spectral, and spatial qualities of each beam are retained, with the generation of 250 fs pulses at 35 MHz repetition rate, an uncompresse...

A space–time optimal power schedule for multiple distributed multiple-input multiple-output (MIMO) links without the knowledge of the instantaneous channel state information (CSI) at the transmitting nodes is proposed. A readily computable expression for the ergodic sum capacity of the MIMO links is derived. Based on this expression, which is a non-convex function of power allocation vectors, a...
Article history: Received on: 08/06/2013 Revised on: 29/06/2013 Accepted on: 15/07/2013 Available online: 31/07/2013 The aim of this study is to evaluate the effects of magnesium and copper sulphates on blood glucose and serum electrolytes levels in fructose-induced diabetic Wistar rats. Diabetes was induced by administration of 20% (20g/100ml) of fructose dissolved in distilled water and admin...
Abstract An autonomous power supply device based on a 30 W fuel cell (FC) stack and hydrolysis-type hydrogen generator was developed. The creation of this included the construction unit for generation, development an electronic control operation device, testing optimizing overall performance. hydrolysis NaBH 4 catalyzed by Pt-based catalysts studied different reactor configurations reagent conc...
Flexible hollow glass waveguides with bore diameters as small as 250 µm have been developed for 3-µm laser delivery. All the guides exhibit straight losses between 0.10 and 1.73 dB/m, and the loss increases to between 2.4 and 5.1 dB/m upon bending 1 m of the guides into 15-cm-diameter coils. This behavior is shown to depend strongly on the launch conditions and mode quality of the input beam. T...
