The solution to the Schrodinger equation in case of Hydrogen atom (single particle) can be
solved exactly. But if we consider many electron atoms the Schrodinger equation could not
solved exactly due to the electron-electron ...
Image processing techniques have become increasingly useful in the vegetable industry, especially for applications in quality inspection and evaluation of food grains, fruits, vegetables, processed foods, and defect sorting. ...

Freshly prepared fruit juices are widely consumed in urban centers of Ethiopia due to their
nutritional value, affordability, and accessibility. However, their microbiological safety
remains a growing public health ...
In this thesis, we have adapted and modified the existing SEIR-SI Mathematical model by adjusting the vertical transmission in humans, where infected mothers pass the disease to newborns, and introducing insecticide spraying ...
Global energy demand is rising, causing overexploitation of fossil fuels and environmental challenges. Renewable sources, especially biomass briquettes from residues, offer sustainable alternatives. Ethiopia relies heavily ...

In this thesis a fluid queue driven by single server Markovian queue with variant working vacation was investigated. Queuing theory is a mathematical approach that studies and models waiting lines. A fluid Queue is an input ...
The study was aimed to evaluate the effect of using a Context-Based Approach (CBA) on the
concept of gas laws on students' understanding and attitude. The study conducted at Ejersa
Goro secondary school in Oromia region, ...
In this study, a mathematical model to analyze the dynamics of a chronic water-borne
disease known as diarrhea is developed. To achieve the objectives of this study work,
secondary data on the population under five years ...
Guizotia scabra sub species schimperi is widely prevalent and commonly distributed type of
weed in Faba beans, Cereals and other varieties of crops species. This research was designed to
analyze the chemical composition ...
One of the biggest and most important domestic tasks is cooking. In rural areas it is usually, it
is done over open flames using fuels like firewood, charcoal, dung, and agricultural waste. An
alternative way to minimize ...

In this thesis an infinite capacity Multi server Markovian queuing system with multiple
working vacations, waiting server, feedback, reneging and retention of reneged customers
is examined. If all active servers finish ...
In this thesis, we discussed numerical solutions of nonlinear Volterra-Fredholm integral equations by using Bernstein polynomial collocation method. Nonlinear Volterra-Fredholm integral equations which cannot be easily ...
This research investigates a single server batch service queuing system with Poisson arrivals, exponential service times and a server that takes variant working vacations. During working vacation, the server continues to ...
Microbial catalases are preferred due to their economic feasibility, rapid growth, high yield, ease of product modification and optimization. Therefore the present study aimed to assess fungal production of catalase from ...

In this thesis, we have examined the limitations of the nonrelativistic Schrödinger equation
focusing on the study of relativistic effects in muonic hydrogen. Muonic hydrogen is an exotic
atom where a muon replaces the ...
This thesis presents a relativistic description of the neutral current (NC) neutrino-induced
associated production of strange particles, in the framework of the Glashow-Salam Weinberg (GSW) model. In the Laboratory (Lab) ...
