  • Zeleke, Beza (Addis Ababa University, 2012-01)
    The Cauchy-Bochner integral representation is extended to holomorphic function of several complex variables belonging to the spaceHs of the collection of generalized functions. The Cauchy-kernel is holomorphic in a tubular ...
  • Admasu, Muluken (Addis Ababa University, 2012-02)
    This paper addresses the dependency of solution of differential equation on initial data and control parameter. To reduce the dimension of the system, we use center manifold reduction method. Mainly, the paper focus on ...
  • Alemu, Dawit (Addis Ababa University, 2018-11-02)
    Textile industry sludge from zero liquid discharge treatment plant of industrial parks in Ethiopia faces environmental problem with no safe disposal options. One potential opportunity for the disposal of sludge is by ...
  • Derso, Getachew (Addis Ababa University, 2011-01)
    The four-color theorem states that any planar graph G = (V, E) can be properly colored using at most four colors. The attempt to prove this famous mathematical problem gave rise to the development of many tools for solving ...
  • Hunegnaw, Dejene (Addis Ababa University, 2017-09)
    In this project we consider the structure of semi groups of self mapping of a semi group S under pointwise composition, generated by the endomorphisms of S. It is shown that,ifS is Clifford semi groups with underlying ...
  • Workalemahu, Kassahun (Addis Ababa University, 2018-01-05)
    The impact of climate change on human health, particularly through the potential increase in vector- and water-borne diseases, has received increasing attention in recent years. Environmental variables are known to a_ect ...
  • Aklilu, Essayas (Addis Ababa University, 2015-06)
    The aim of this study was to investigate and compare the bionomics, ecology and behaviors of the vector (s) of visceral leishmaniasis (VL) in two endemic and ecologically distinct areas of northwestern Ethiopia. This ...
  • Mohamed, Esmael (Addis Ababa University, 2015-08)
    Students are facing problem in understanding of what they are learning in mathematics lesson. There are a lot of students who are suffering from the conceptual change of mathematics. To conduct the study, a group circulation ...
  • Taye, Abebe (Addis Ababa University, 2014-06-27)
    In this Project some necessary and sucient optimality conditions for the weakly ecient solutions of vector optimization problems (VOP) with nite inequality constraints are shown by using constraints qualications in ...
  • Setargie, Abebe (Addis Ababa University, 2016-08)
    Quadratic programming is one of the types of . There is no single method available for solving quadratic programming problem. So a number of methods have been developed for solving quadratic programming problems. In this ...
  • 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 ...
  • Yohannes, Flagot (Addis Ababa University, 2012-01)
    Let be a continuous function on, and suppose is a smooth nonlinear function. Such functions arise in many applications, and very often minimizers are points at whichis not differentiable. Of particular interest is the case ...
  • Buli, Bizuneh (Addis Ababa University, 2017-07-03)
    Background: Hospitals information system is a system for collecting, processing, analyzing, disseminating and using information about a patient health service and community health desires of the population. Hospital ...
  • Misgan, Yonathan (Addis Ababa University, 2020-06-04)
    Nowadays, in many domains, managing data according to local convention is required to be taken into account. Due to this, most of the existing system environments include the models for internationalization to allow developer ...
  • Gidey, Gebretsadik (Addis Ababa University, 2013-06-27)
    A function f de_ned on a given convex set X which can be expressed as a di_erence of two convex (continuous) functions is called d.c function or _-convex function. The functions which are Lipschitz and bounded variation ...
  • Alemu, Yoseph (Addis Ababa University, 2014-09)
    The discrete time predator prey model in two dimension is investigated. Thefixed points are obtained and their stability is analyzed. Prey predator solution and bifurcation diagram are presented for selected range of ...
  • Tsegay, Hailegebriel (Addis Ababa University, 2011-06)
    In this Project, we introduced the affine varieties, which are curves and surfaces (and higher-dimensional objects) defined by Polynomial Equations. By considering ideals in the polynomial ring 1,…], we also understood the ...
  • Tadesse, Hagos (Addis Ababa University, 2012-01)
    The complete set of this project paper focuses on direct product and convolution of generalized functions. I have discussed the definitions, properties of direct product and convolution of generalized functions and also ...
  • Gebreegziabher, Tewelde (Addis Ababa University, 2020-07-14)
    Chanrasekharan and Narasimhan in [2] have shown that the functional equation Γ(s)ϕ(s) = Γ(δ−s)ψ(δ−s) is equivalent to two arithmetical identities. In [5] Hawkins and Knopp proved a Hecke correspondence theorem for ...
  • Cherkos, Meseret (Addis Ababa University, 2011-01-25)
    This project is based on equations that allow us to compute the value of a function recursively from a given set of values. In the main, Hartman-Grobman theorem is proved by using different lemmas and other theorems. ...
