Analytical Comparison of Path Loss Models for Radio Wave Propagation over Yenagoa–Southern Nigeria

C. Emeruwa & E. J. Oduobuk · Asian Journal of Physical and Chemical Sciences · 2023

Using propagation models helps with communication system planning and maximizes the use of the radio spectrum, a limited natural resource. Here is a comparative analysis between some propagation models and actual measurements from Yenagoa, Southern Nigeria. Electric field strengt...

Time Steps Distribution in Numerical Technique: A Comparative Analysis of Third and Fourth Order Runge-kutta Algorithms

C. Emeruwa & U. J. Ekah · Asian Journal of Research and Reviews in Physics · 2023

To analyze a harmonically Van der Pol oscillator, this work used a combination of graphs, time steps distribution, adaptive time steps Runge-Kutta, and fourth order algorithms. The goal is to examine the performance of third and fourth order Runge-Kutta algorithms in finding chao...
