Photovoltaic Power Stations (PVPS)
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 5
Qatar declared that by 2020 solar energy would produce at least 2% of its total generated electric power (EP). The known solar power plants EP at utility scale level are concentrating solar power (using parabolic trough collectors, linear Fresnel collector, and solar tower), photovoltaic (PV), and integrated solar combined cycle using fossil fuel (natural gas) besides solar collectors. E...

Reflection and Transmission of Elastic Waves at a Loosely Bonded Interface between an Elastic Solid and a Viscoelastic Porous Solid Saturated by Viscous Liquid
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 3
In the present paper, a problem on reflection and transmission of elastic waves at a loosely bonded interface between an elastic solid and a viscoelastic porous solid saturated by viscous liquid is studied. The study is carried out with the assumption that the interface behaves like a dislocation which preserves the continuity of stress and allows a finite amount of slip. The appropriate...

Empirical Methods of Capacity Estimation of Urban Roads
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 3
Determination of road capacity is a major issue for transport planners. Capacity is defined as the maximum number of vehicles that can be accommodated per unit time under given condition of occurrence. Capacity studies for heterogeneous traffic situations are very complex and only limited studies undertaken. Here again there are several methods of estimation of capacity. However the majo...

Trace Elements Distribution in Soil Columns as affected by Cassava Effluents Application
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 3
Cassava effluent in form of wastewater obtained during the processing of “garriâ€Â, is indiscriminately released into the environment, the effect of which is not fully known on soils and groundwater. This study investigated the distribution of two trace elements (Cu and Mn) found in the effluent through soil columns. The experiment was conducted using three dif...

Beam Steering of an Array Antenna using Tunable Multi Layer Multi Dielectric-High Impedance Surface Reflector
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 2
Beam scanning have found great demand in the field of wireless communication, satellite communication, radar, etc. [1,2]. These applications are generally covered by phased array antennas [3], where several elements are grouped together in a linear or planar special configuration. The radiated beam is determined by the vector addition of the electromagnetic fields radiated by the individ...

Performances of OFDM/OQPSK Modulation for Optical High Speed Transmission in Long Haul Fiber Over 1600 Km
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 2
Orthogonal Frequency Division Multiplex (OFDM) is a high-speed transmission technique widely studied in wireless networks. Its potential presents it as an ideal solution for high-speed transmission in optical fiber networks. This study presents the OFDM modulation associated with Offset Quadrature Phase Shift Keying (OQPSK) filtered using a filter banks for an optical transmission at the...

The Algerian Experience in the Waterproofness of the Bituminous Concrete Masks Advantages and Inconveniences
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 2
The experience of the use of bituminous concrete upstream facing is presented in Algeria in the four big dams: Ghrib (1926-1938), Bouhnifia (1930-1941), Sarno (1947-1954) and Ighil Emda, The problem posed in the aroused dams is especially delicate because of the instability of the mask which could become precarious to the temperature. Therefore it was covered with a thermal protection, w...

X-Ray Switching Study on Thin Film Silicon Photovoltaic Solar Panel
Published In: GJRE Part: J: General Engineering Volume: 14 Issue: 1
Thin film silicon solar panels are subjected to switching study under high energy X-Rays exposures. Photo current of unbiased cell is recorded with time at short regular intervals (10 sec) at room temperature. These exposures develop reproducing photocurrents. Long exposures (Kilo second) are found to degrade the photocurrent almost linearly at a rate 2.4X10-14A/s. Solar panels are found...
