The main purpose of this project is to show the application of the Mohand transforms with the Adomain decomposition method for solving Volterra-Fredhom integro-ordinary differential equations. The basic concepts of Mohand ...

Post-sunset ionospheric irregularities are common features of the equatorial ionosphere that affect radio communication and navigation systems. It is known that these irregular ities have shown longitudinal and temporal ...

The ionosphere, a critical region of Earth’s upper atmosphere, serves as a fundamental medium for various essential technological applications, including satellite communication, navigation systems, and radio propagation. ...

Abstract Organic light emitting diode contain couples of thin film layer, and efficient balanced holes and electrons injection is needed so as to have efficient device. Here, the injection is critical at around organic ...

Abstract In this study the experimental data’s from the Nd: YAGQ-switched nanosecond (ns) laser produced Cu plasmas at lower pressure were used. The electron density have been determined from the Stark broadening of ...

Rainfall causes natural disasters such as floods that people around the world face every year. Rainfall prediction is of great importance for countries like Ethiopia, whose economy is heavily dependent on agriculture. ...

The thesis delves into a comprehensive examination of Total Electron Content (TEC) data gathered from both GPS and Ionex models in Bahir Dar, Ethiopia, spanning the years 2008 and 2015. This investigation meticulously ...

Silver nanoparticles (AgNPs) exhibit unique optical properties due to their localized surface plasmon resonance (LSPR), which is influenced by their size, shape, and synthesis method. This study aims to explore and compare ...

This study investigates the extent of solar ultraviolet radiation (UVR), wavelength ranges from 280nm-315nm which is called UV-B, distribution in Bahir Dar and Ras Dashan.On the other hand, when materials exposed to ...

A need for high gain and low power operational amplifiers (op-amps) exist for certain applications. This requires research in the area of its gain and lowering power consumption without affecting other parameters drastically. ...
