  • Yeneabat, Shiferaw (Addis Ababa University, 2017-09)
    In this thesis, using the properties of convergence of Fourier series and some other properties of trigonometric polynomials, in particular that they are sums of holomorphic and anti-holomorphic functions, we are able to ...
  • Yemane, Gediyon (Addis Ababa University, 2011-01)
    This project is a reading material in all Complex Analysis. It deals mainly with the class of Analytic Functions on an open set G. Our purpose is to describe this class of analytic functions is complete metric space with ...
  • 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 ...

  • Assefa, Emnet (Addis Ababa University, 2013-06)
    This project discribes the concept and properties of tiling of the plane with regu- lar polygones. The regular tilings that is a monohedral tilings whose tiles is regular polygones and semi regular tilings that uses a ...
  • Humer, Mafuz (Addis Ababa University, 2020-06-05)
    Many real world problems can be modelled using different forms of differential and integral operators. Due to this, studying various properties of these class of operators have been an important area of research in ...
  • Abate, Wossenu (Addis Ababa University, 2017-06)
    The transfer function of a linear time-invariant system describes the input output behavior of the system when all initial conditions are zero. Hence, it should be independent of the state variables used in a state space ...
  • G/anenya, Haftom (Addis Ababa University, 2012-02)
    The complete set of this paper focuses on minimal cost multicommodity network flow problem especially on transportation problem. decompose it in to minimal cost single commodity transportation problem based on their special ...
  • Gebremedhin, Henok (Addis Ababa University, 2013-07-02)
    A variety of applications arise in Mathematics with the growing concepts of Graph Theory. Among the different applications; one of thefirst Optimiza- tion problem studied in operations research is the Transportation ...
  • Merga, Gashaw (Addis Ababa University, 2015-04)
    The objective of this project is to minimize total transportation cost plus penalty cost for shortage of supply. The work focused on formulating transportation problem under shortage of supply and penalty for unmet ...
  • Adefris, Nahusenay (Addis Ababa University, 2015-10-16)
    The Ordinary Transportation Problem allows to model the situations where the amount of goods leaving the supply points is equal to the amount deliv- ered to the destinations. In this project, the model of Transportation ...
  • Yimer, Ibrahim (Addis Ababa University, 2014-03-03)
    This paper concerns the existence of solutions of a second order non linear boundary value problem with a derivative depending non linearity and posed on the positive half line. The derivative operator is time dependent. ...
  • Kefyalew, Erimyas (Addis Ababa University, 2016-07-12)
    Elliptic partial dierential equations appear frequently in various elds of science and engineering. These involve equilibrium problems and steady state phenomena. The most common example of such equation is poisson's ...
  • Fisseha, Tirhas (Addis Ababa University, 2018-08-30)
    The variational formulation of boundary value problems is valuable in providing remarkably easy computational algorithms as well as an alternative framework with which to prove existence results. It is given that the ...
  • Wasihun, Dereje (Addis Ababa University, 2020-11-11)
    We introduce the notion of Weak idempotent ring (WIR, for short) which is a ring of characteristic 2 and a4 = a2 for each a in the ring. We obtain certain properties of this class. Further we provide examples of weak ...
  • Lemma, Hannibal (Addis Ababa University, 2012-06)
    After a detail demonstration of AES (Advanced Encryption Standard) , we explained the procedure of changing the key-recovery problem of AES-128 to a zero dimensional ideal from a single plain text /cipher text pair. ...
