Free space optics communication system design using iterative optimization
Gebrehiwet Gebrekrstos Lema
Free Space Optics (FSO) communication provides attractive bandwidth enhancement with unlicensed bands worldwide spectrum. However, the link capacity and availability are the major…
Dynamics of a Stochastic COVID-19 Epidemic Model with Jump-Diffusion
Almaz Tesfay, Tareq Saeed, Anwar Zeb +3
For a stochastic COVID-19 model with jump-diffusion, we prove the existence and uniqueness of the global positive solution. We also investigate some conditions for the extinction a…
Stochastic Bifurcation in Single-Species Model Induced by α-Stable Levy Noise
Almaz Tesfay, Daniel Tesfay, Shenglan Yuan +2
Bifurcation analysis has many applications in different scientific fields, such as electronics, biology, ecology, and economics. In population biology, deterministic methods of bif…
Mean Exit Time and Escape Probability for the Stochastic Logistic Growth Model with Multiplicative α-Stable Lévy Noise
A. Tesfay, D. Tesfay, A. Khalaf +1
In this paper, we formulate a stochastic logistic fish growth model driven by both white noise and non-Gaussian noise. We focus our study on the mean time to extinction, escape pro…
A Simulation Based Performance Evaluation of Optical Ethernet Switch
Dawit Hadush Hailu, Gebrehiwet Gebrekrstos Lema, Gebremichael T. Tesfamariam
With the advent of several new Cloud Radio Access Network (C-RAN) technologies, todays networking environment is dramatically altered and is experiencing a rapid transformation. On…
Feasibility study of antenna synthesis using hyper beamforming
Gebrehiwet Gebrekrstos Lema, Dawit Hadush Hailu
Wireless communication requires an effective antenna synthesis that characterizes adequate infrastructures to provide the broader bandwidth and reduced interference. Antenna design…
