Design and implementation of a model (ADS-3G) of a traffic light using automated solar power supply
In this work, a model of an automated traffic light controller (ADS - 3G) had been designed, simulated, tested and implemented, using experimental techniques in electronic engineering, to manage the traffics at the busy four way junctions along Sahuda road in Mubi North Adamawa State, Nigeria. The designed was achieved with the help of 12V automated solar energy power supply, time base (555 timer), decade counter,...

An application of FDTD using quadratic extrapolation
Finite difference time domain (FDTD) has been the most obvious choice of researchers to simulate an electromagnetic environment which is quite complex in nature. But the amount of time consumed in running the simulation has always been the limiting factor. In this work, a time efficient FDTD tool that is, Quadratic FDTD is developed and used for simulation of a rectangular cavity resonator. Traditional FDTD simulation...

Measurement of exposure of radio frequency field (RF) radiation from global system for mobile communication (GSM) masts
The objective of this study is to draw a conclusive position on the effect of radiofrequency (RF) radiation from GSM masts on human health. The measurement of the RF was conducted at 100 m and 200 m away from the masts of the major GSM operators in Nigeria; GLO, MTN and ZAIN. The data obtained were analyzed using correlation analysis to establish the fact that whether with time exposure to RF will have discernable...
