Ethiopia. situated in the Ilorn of Africa. shows wide variation in topography climate and land use distribution. It has a high population of livestock. However. the prevalence of a number of important diseases has impeded ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
The main purpose of this study was to assess the implementation of five in one, group work and pair work cooperative learning in Cheha District general secondary schools. To conduct the study, survey design was employed. ...
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 ...
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 ...
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 ...
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 ...
This project is concerned with the enumeration of a combinatorial object, ordered tree, with respect to different parameters such as, number of edges, vertices, and path lengths. A known combinatorial argument is used ...
A differential equation is the most important part of mathematics for understanding many of the basic laws of physical sciences as well as other sciences. Some of the laws are formulated interms of mathematical equations ...
The complete set of this project focuses on solvability of the Dirichlet problem of the type _ Δ_ = u=f __ Ω _ = u _Ω and the Neumann problem of the type _ Δ_ = u __ Ω __ __ = ℎ __ _Ω . The explicit solutions ...
So far, many things were said about differential equations without time delay, the so called ordinary differential equations or partial differential equations, and their solutions. The fixed point theorems have been used ...
The complete set of this paper focuses on k-shortest path problem and algorithms which solve k-shortest path in a graph G where V is set of n nodes and E is set of m arcs. and I have discussed how to compute the first, ...
In this work our definition of Semiring is given without zero 0 and unity 1. The focus of the study is to give appropriate evaluation on Semirings which have their own related properties with Distributive lattices. We prove ...
In analysis, if we consider thespace, the Riesz representation theorem states that, if is a bounded linear functional on spaces, with 1≤<∞ and μ be a -finite measure then there is unique element where 1=1 , such that ...
