Due to the problem associated with device power dissipation, the demand for low
power devices is increasing at a faster rate as a result of wider implementation of
smaller-sized, portable, and hand held devices in the ...
Ionospheric irregularities were small-scale fluctuations or disturbances in the ionosphere, the
part of the Earth's atmosphere that is ionized by solar radiation. These irregularities can affect
radio wave propagation ...
Metal oxide nanoparticles have gained significant attention in recent years due to their unique
properties and potential applications in various fields. However, the size of these nanoparticles plays a
crucial role in ...
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 ...
Solar radiation at the earth‟s energy source including a significant amount of ultraviolet
rays. Ultraviolet B (UV-B) is one of the types of UV radiation with wavelength range from 280315
nm.
In

The ionosphere is the part of the atmosphere that contains ionized gases, called plasma,
and that affects radio propagation. The response of the ionosphere and magnetosphere to
two powerful geomagnetic storms that occurred ...
This thesis investigates the impact of geomagnetic storms on the global ionospheric Total
Electron Content (TEC) during selected events from April 2023 to August 2024. The primary
objective is to analyze the dynamic ...
Ionosphere, is a thin layer of plasma that occupies the upper layer of the Earth's atmosphere,
affecting radio communications, satellite navigation, and space weather. For this reason,
monitoring changes in the ionosphere ...
The demand for maximum performance parameters, with some level of trade-o but
not too much compromise between di erent parameters, from CMOS op-amp circuits
in general and two stage CMOS op-amps in particular is driving ...
The ionosphere, also known as the ionized part of the upper atmosphere, is believed to vary as
a function of different parameters such as solar and geomagnetic activities. One of the
peculiar parameters that describe the ...
The main objective of this research is to enhance the DC open loop gain and voltage
swing of a Telescopic CMOS op amp by using OrCAD PSPICE design and simulation
software, based on electronic devices and advanced integrated ...
The need to design and manufacture CMOS amplifiers to maintain acceptable level of
performances at low voltages is immensely important. This research work emphasizes
on investigating the CMRR, slew rate, and DC gain of ...
This study investigated the temporal variations of solar UV radiation during Solar
Cycles 23 (1996-2008) and 24 (2009-2020). The broader implications of the UV
irradiance variation for Earth’s atmosphere, climate and ...
This graduate project work focuses on the practical application of Josephson tunneling.
Using the time-dependent Schrödinger equation, we derived the mathematical
expressions for current density (J), phase difference , ...
This study focuses on synthesizing, characterizing, and exploring the electrochemical
properties of resorcinolate, 2,2’-bipyridine, and their Cu(II) metal complexes. Various
techniques such as FT-IR, UV-Vis, ICP-OES, ...
The purpose of this study was to identify and analyze the problems faced by teachers in
teaching mathematics at Adet town administration secondary schools West Gojjam, Amhara
Region, Ethiopia and also to find causes ...
Birds are the most known animals however; the majority of avian species have been threatened
as a result of habitat modifications. The aim of this study was to investigate diversity, relative
abundance and habitat ...
The textile industry is one of those industries that discharges great amounts of effluents with
synthetic dyes into the environment, causing public concern. This study focuses on the
effectiveness of Ethiopian kaolin, a ...
Transition metal complexes are a promising class of compounds as antibacterial
agents for inhibition of bacterial infectious diseases.
