No other Ethiopian laws/proclamations have attracted as much attention as the CSPrn621/2009. Ever since its inception over six years ago, it has aroused considerablernattention and debate from a great variety of concerned parties. Despite this, the author isrnnot aware of any previous comprehensive...
Lignocellulosic materials (e.g. Waste cartons) can be utilized to produce carboxymethylrncellulose, a water soluble, biodegradable anionic polymer. This study involved productionrnand optimization of carboxymethyl cellulose from waste cartons. The conversion of wasterncartons to CMC can be achieved...
Background: Among all liquids, water is a unique substance and one of the most important natural resources. In the absence of safe and adequate drinking water supplies, diseases such as diarrhea, skin and eye infections are common. Treatment methods were thus required in order to protect the health...
Nonlinear first order equations are typically hard to solve without some conditionsrnplaced on the PDE. In this project I used to present the Method of Characteristics andrnAuxiliary system of equation to solve first order nonlinear Partial Differential Equationsrnusing Lagrange’s and...
The present study on avian diversity based on habitat difference was conducted at Geto and Gembejo in Kersa Malima Woreda in Southwest Shoa Zone of Oromia region, Ethiopia. Six habitats were identified for counting birds using line transect and point count methods. Data were analyzed using...
In this paper we give sufficient conditions ensuring that the periodic solutions for a class of second order differential Equations and positive periodic solutions of second-order differential equations ; system of periodic solutions for autonomous and nonlinear differential equations, each of...
Currently there is a widely shared understanding that Business Process Reengineeringrnhas transformed the service delivery performance of many government institutions atrnfederal, regional as well as local levels. Processes which had been taking months orrnyears with high cost have been made to be...
This thesis focuses on studying and reviewing the design and performance aspects of III-V Solar cells;rnand make a comparison among the solar cells on GaAs, Ge, and Si substrate mainly based on efficiencyrnand cost. The performances of 1-junction GaAs and 2-junction InGaP/GaAs solar cells on GaAs...
Overcrowding is one of the major problems that impede quality of services at Amanuel Mental Specialized Hospital, especially at outpatient department. Overcrowding at outpatient department deters easy movement of both staff and patient which hinders appropriate use of available space in the...
This project addresses the solution of unconstrained optimization problems usingrnalgorithms that require only values with out using derivative (derivative free ) ,the algo-rnrithms generate a sequence with an initial point x0 and direction dk and step length rnand look for best point (next...
Designing a vision system, which was motivated by that of the human eye, has been done since the introduction of digital computing devices. Due to its abundant applications, this area is a hot topic in the industry. Its computational complexity hinders it from the required accuracy and flexibility...
Trees and shmbs screened for desirable properties can play an important role in thernrehabilitation of degraded lands. Indigenous species adapted to harsh conditions ofrndegraded sites can reverse degradation processes by stabilizing soils, increasing organicrnmatter and improvements of nutrient...
This study is carried out based on the objective to identifo factors affecting internetrncllstomers ' satisfaction by believing that it will contribute a lot for the modernizationrnprocess with new internet and related technology based opportunities for transactionrnthrough providing firms with new...
This study examines the Community based health insurance Enrollment/practice & challenges inrnEthiopia by taking Aleltu district as case of study. The study, with the prime objectives of to findrnout & mention the roots of problems & was geared towards answering key research questionsrngermane in...
Modeling and simulation of Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) isrnvery essential in order to understand the device physics, electrostatics and other importantrnphenomena occurring in this device. Therefore, in this thesis the modeling and simulation ofrnSilicon Nano Wire...
In an attempt to examine the growth-environment relationship in general, and in order to investigate an environmental Kuznets curve (EKC) for carbon dioxide (CO2) emission in particular, this study employs data spanning from 1981 to 2013. The Johansen co-integration test and error correction model...
Algebraic Geometry can be used to prove geometric theorems in Euclidean Plane Geometry. This can be done when the geometric theorem has the property that the hypothesis and the conclusion of the theorem can be translated into polynomial equations. Such theorems are called admissible theorems. The...
This study was instigated by the fact that even though school improvement program (SIP) was being implemented with observable challenges like inadequate participation of stakeholders, lack of experience and skills among school principals, low coordination of school community that might have...
In this thesis we designed and synthesized 3D graphics accelerator Intellectual Property (IP) using VHDL. The main parts which were designed in this work include: the geometry unit and the rasterizer unit of 3D graphics pipeline. The geometry unit design contains two main parts , the matrix...
In 2001, National Institute of Standards and Technology (NIST) approved Rijndael asrnAdvanced Encryption Standard(AES).Since its approval, AES is being used widely in differentrnsecurity applications for its good security, simple design and hardware suitability.AES can bernused to encrypt any...
