For the cellular networks to effectively cover a terrain or environment, accurate prediction of the coverage of the radio frequency signal is highly needed. Wave propagation models are essential and very important tools for determining the wave propagation characteristics for a particular environment. Path loss predictions are therefore required for the(More)
The tendency of a concrete material to deform under stress is often responsible for excessive deflection at service loads which can compromise the performance of elements with a structure. Hence, the realistic prediction of both the magnitude and rate of creep strain is an important requirement of the design process. Therefore, relatively simple empirically(More)
