An endeavour is made in the present study to identify the groundwater potential zones in the Pulang River basin, Cuddapah district based on the Geological and Geo-electrical investigations. The Geomorphological features and lineament patterns are also studied in locating favourable sites for groundwater. The Geoelectrical soundings conducted at hundred locations in the basin area are interprete...
The paper is devoted to the problem of determining geoelectric structure soil within procedure testing grounding arrangements existing power plants and substations required depth in conditions dense development. To solve problem, it was proposed use Schlumbergers method , which has a greater sounding compared Wenner electrode array. purpose work develop mathematical model for interpreting resul...

The first stage of the project including construction and operation of a prototype system has now been completed and the ...
I This paper focusses on the characterization and optimization of multicarrier technologies applied to PLC communications in the CENELEC band A. First, we will give a short description of the PLC test bench used by Schlumberger [1] and summarize the key tests that are applied to evaluate a communication technology. In the second part, we will present the key parameters of the multicarrier modul...
