  • Aklilu, Kibremarkos (Addis Ababa University, 2017-06)
    Control theory is an area of applied mathematics that deals with principles,laws, and desire of dynamic systems. Optimal control problems are generalized form of variation problems. A very important tool in variational ...
  • Balew, Haimanot (Addis Ababa University, 2012-01)
    In spite of the fact that the origin of non-smooth optimization as a mathematical discipline is quite recent; it is now well established as an important and very active branch of applied mathematics. Many practical ...
  • Teka, Haftu (Addis Ababa University, 2011-06)
    We construct a quotient group by fuzzy normal subgroup and we prove the corresponding Isomorphism Theorems. Obtained results are used to the characterization of selected classes of quotient groups
  • Lakew, Zenebe (Addis Ababa University, 2016-07)
    Certain techniques fundamental to the study of algebra. One of such techniques is the construction of a quotient set of an algebraic structure by a means of an equivalence relation on the given set. Based on this, we ...
  • Gebrehanna, Birhanu (Addis Ababa University, 2014-02)
    The r-Bell number ^Br(G) of a simple labeled graph G is the number of partitions of its vertex set whose blocks are independent sets of G where the _rst r-vertices are in di_erent blocks. The number of these partitions ...
  • Brhane, Tsegay (Addis Ababa University, 2011-01)
    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, ...
  • Abiy, Meseret (Addis Ababa University, 2017-06)
    The linear time invariant discrete-continuous systems, studied in this work, contain the two coupled subsystems: subsystem with continuous-time dynamics and subsystem with discrete-time dynamics. Continuous dynamics is ...
  • Hunde, Natea (Addis Ababa University, 2017-03)
    This thesis is devoted to a study of real holomorphy rings in R(x) and elliptic function _elds R(x)(p f(x)); f is a monic polynomial of degree 3 with no multiple roots in C over R and sums of powers in R(x). The objects ...
  • Tesfaye, Kassahun (Addis Ababa University, 2011-01)
    The purpose of the study was to investigate Neural Networks in general and Recurrent Neural Network in particular. The investigation was to construct a model that shows the complex data processing of these Neural Networks ...
  • Worku, Getnet (Addis Ababa University, 2015-01)
    Qusidi_Erentiable Optimization Plays A Vital Role In The Study Of Non Smooth Optimization Problems. The Quasidi_Erential Of A Quasidi_Erentiable Function Is A Pair Of Compact Convex Sets In A Locally Convex Topological ...
  • 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 ...
  • Tolcha, Solomon (Addis Ababa University, 2013-06)
    A labeling of a graph G is an assignment of integers to the edges,vertices or both edges and vertices of a graph subject to certain conditions. A vertex-sum for a labeling is the sum of the labels on edges incident to a ...
  • Gebremelak, Beza (Addis Ababa University, 2017-10-02)
    Standard penetration test (SPT) is widely practiced in Ethiopia to define fine grained soils’ strength parameter for bearing capacity analysis in foundation design. However, there is no published correlation between the ...
  • Tesfaw, Yassin (Addis Ababa University, 2013-07-02)
    Combinatorics on words has imposed itself as a powerful tool for the study of large number of discrete, linear, non-commutative objects. This report project is intended to discuss words, in particular, repetition in words ...
  • Jifara, Worku (Addis Ababa University, 2011-01)
    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 ...
  • Alemu, Temesgen (Addis Ababa University, 2014-08)
    This project shows a simple method of solving _rst order non-linear equation and scalar conservation law of the form ut+A(u)ux = 0 with initial condition u(x; 0) = f(x) in one dimensional wave equation,shock wave and ...
  • Tamene, Aynadis (Addis Ababa University, 2018-06-02)
    Folate is an essential nutrient in the diets of humans involved in vital functions of cell metabolism. It is currently one of the most actively studied vitamins. This is mainly due to its well established role in preventing ...
  • Lemma, Brook (Addis Ababa University, 1983-12)
    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 ...
  • Biset, Tesfa (Addis Ababa University, 2015-06)
    A singular boundary value problem associated with the 8-Laplace equation having, in general a non-separable inhomogeneous term is considered. The existence of ground state solution in viscosity sense to such a problem ...
  • Fantahun, Adane (Addis Ababa University, 2011-02)
    This project work contains two parts: sobolev spaces and application to elliptic partial differential equations. The theory of sobolev space has been originated by Russian mathematics S.L sobolev around 1938. These ...
