The purpose of this study was to investigate the major factors that influence the implementation of mathematics curriculum in general secondary schools. Attempts have been made to examine: - the attitude of mathematics ...

Diversity, Distribution and Relative Abundance of the Avian Fauna of Chebera Churchura National Park, Ethiopia

W/Yohannes, Dereje (Addis Ababa University, 2006-06)

The aim of this study is to investigate the diversity, relative abundance and habitat association of the avian species in Chebera Churchura Nation Park (CCNP). The study was carried out using the method of Timed-Species-Count ...

Three-Person Cooperative Game and its Application in Decision Making Process of Hierarchical Organizations

Dejenee, Abiy (Addis Ababa University, 2007-08)

The solution of an n-level linear problem, when the levels make decisions se- quentially and independently, is not necessarily pareto-optimal, i.e.there exist feasible points which o®er increased payo®s to some levels ...

Linear Three-Level Programming Problem With the Application to Hierarchical Organizations

Lakie, Esubalew (Addis Ababa University, 2007-08)

In many decision processes there is an hierarchy of decision-makers and deci- sions are taken at di®erent levels in this hierarchy. The decentralized planning problem has long been recognized as an important decision-making ...

Nonlinear Transportation Problems

Terefe, Kidist (Addis Ababa University, 2007-08)

Some times there may be many di®erent ways to model a particular problem, choosing the best one minimizes the complexity of the problem and time to solve. Since, as we have said earlier, any programming problem with ...

Ideal theory of Subtraction Algebras

Zerihun, Nigatu (Addis Ababa University, 2008-06-06)

This project work concentrates on the ideal theory of subtraction algebras. We start it with lattice, semi-lattice, Boolean algebra, supremum and infimum of a set. The main body of the project recapitulates subtraction ...

Reduction of Sturm-Liouville Boundary Value Problem in to Integral Equation

Tesfamariam, Gerensea (Addis Ababa University, 2010-03)

In this paper we present a method of fnding eigenvalue and eigenfunction for linear second order elliptic dierential equation using the Fourier method. Then we present more specically for one dimension space called ...

Generalized Solution of Inhomogeneous Differential Equations

Tesfaye Yohannes (Addis Ababa University, 2010-06)

We study the method to find a generalized solution to the linear inhomogeneous differential equations of different orders. Here first, second and fourth order linear inhomogenous differential equations are considered. We ...

Conformal Mappings and the Riemann Mapping Theorem

Welay, Kewani (Addis Ababa University, 2010-06-06)

It is easy to point out that any function of a complex-variable can be considered as a mapping from one complex plane into another. A great deal of attention is devoted to the study of holomorphic functions. The reason ...

Graduate Seminar Report on Quadratic Programming on Sphere

Gebre, Kalayu (Addis Ababa University, 2010-06-06)

Quadratic programming on a sphere is a special class of non linear programming quadratic objective function with a single quadratic constraint. To solve this problem we can apply different methods and the Lagrangian dual ...

Harmonic Functions on a Disc and Upper Half Plane

Wolde, Moybon (Addis Ababa University, 2010-06-06)

This seminar report is devoted to the study of harmonic functions on disc and upper half plane. These functions are closely connected to analytic functions since the real and imaginary parts of analytic function are harmonic ...

Stability Iin Non-Linear Ordinary Differential Equations

Daba, Yitagesu (Addis Ababa University, 2010-06-06)

Many important physical problems arising in Engineering and applied science are modelled directly or indirectly by ordinary differential equations which are actually non-linear. Therefore, the paper is concerned with ...

Asymptotic Solutions of Ordinary Differential Equations Having an Irregular Singular Point

Yesuf Jemal (Addis Ababa University, 2010-06-06)

The problem of finding a basis solution of linear homogeneous ordinary differential equations with variable coefficients is, in general difficult. Indeed a considerable effort was directed at constructing solutions of ...

Integral Equations and S ome Basic Preliminary Concepts

Hailu, Abraham (Addis Ababa University, 2010-06-06)

In certain problems that we encounter it is common to get equations in which the unknown function occurs under an integral sign. Such equations are termed as integral equations. Integral equations are use full to solve ...

The Basic theory of Sturm-Liouville Boundary Value Problems

Assefa, Woldegebriel (Addis Ababa University, 2010-06-06)

In this paper we shall present the basic theory of Sturm-Liouville boundary value problem (BVP) together with a discussion of some of the powerful methods that are used to solve the Sturm-Liouville boundary value problem ...

Derivative Free Optimization

Abraha, Teklebirhan (Addis Ababa University, 2011-01)

We will present derivative free algorithms which optimize non-linear unconstrained optimization problems of the following kind: minxEnRmff (ff:R nn→R The algorithms developed for this type of problems are categorized ...

The Motzkin Numbers and their Combinatorial Interpretations

Ararsa, Shibru (Addis Ababa University, 2011-01)

This project paper is divided into four sections. we discuss the origin of Motzkin numbers using the division of finite number of points on a circle by non-intersecting chords. The idea of division of finite number of ...
