Multiples in Onshore Niger Delta from 3D prestack seismic data

The presence of multiples has been investigated in Onshore Niger Delta using 3D seismic data. The aim of the study was to investigate the characteristics of reflection events beyond 3s two way time on seismic data behind the boundary faults associated with the shadow zone.  This involves detailed velocity analysis on semblance plot panel and accounting for moveouts due to reflections away and within the shadow...

Calibration and estimation of efficiency of Geiger Muller counter using a standard radioactive source

The beta counting system uses a Geiger-Muller (GM) tube to detect the presence of beta contamination present in filter paper samples or in planchet samples.  The counting system is enabled with a provision to count the samples at various distances from the detector to the sample position.  The efficiency of the counting system is provided by the manufacturer at the time of procurement which is calibrated and...

Energy saving by applying the fuzzy cognitive map control in controlling the temperature and humidity of room

This paper investigated the implementing of soft computing methodology of fuzzy cognitive map on controlling parameters of heating, ventilating and air-conditioning systems. In the past few years, many researches have been done on application of different controllers on heating, ventilating and air-conditioning system as a more energy consuming part of the building automation system. Unlike the conventional control...
