  • Kuma, Yetneberk (Addis Ababa University, 2011-06)
    This project is conserned with a network and its applications. The project begins with pre-concepts of graph theory and focuses on one of the the well known application of graph theory called networks. The project on its ...
  • Wosene, Workeneh (Addis Ababa University, 2013-02)
    In this paper we study some of the non-oscillatory criteria on half- linear di_erential equation of the form (r(t)_(x)+(T)-=0Where (z)=(x)p-z z-p>1 Using modi_ed Riccati technique. In addition to that we are going to ...
  • 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 ...
  • Amare, Getinet (Addis Ababa University, 2017-11-06)
    Stochastic chance-constrained programming is mainly concerned with the problem that the decision maker must give his solution before the random variables come true. In this problem, the probability of decision satisfying ...
  • Kiyak, Anteneh (Addis Ababa University, 2019-07-02)
    This thesis concentrates on numerical methods for solving hyperbolic un- coupled PDEs systems with two independent variables (space and time)and whose model problem is vt +Avx = 0 for which A is assumed to be a diagonalized ...

  • Molla, Fetene (Addis Ababa University, 2019-06-03)
    This project provides a practical overview of numerical solutions to the wave equation of nite string using the nite di erence method. The second order central di erences for time and space is applied to a problems ...
  • Getachew, Frether (Addis Ababa University, 2013-02)
    This work deals with Central Delannoy numbers, enumerated as Dn;n = (Dn)n_0 = 1, 3, 13, 63, 321, 1683, 8989, 48639, . . ., which counts the number of lattice paths running from (0; 0) to (n; n) by using the steps (1; 0), ...
  • Jundi, Abdurahman (Addis Ababa University, 2017-06)
    This project paper is aimed to explain observability of linear time invariant dynamical system. We develop a linear systems theory that coincides with the existing theories for continuous and discrete dynamical systems. ...
  • Getachew, Biruk (Addis Ababa University, 2013-06)
    Hankel transforms are among the well-known transforms. In this paper integer Hankel transforms, Riordan Matrices and generating functions are defined. We also examine a set of special Riordan arrays, their inverses and ...
  • Hailu, Abraham (Addis Ababa University, 2016-06-30)
    In this thesis, we study the application of FBI transforms to the C1; analytic and Gevrey wave front sets of functions. We characterize the C1 wave front set of a function by providing a simpler proof of a result by ...
  • Damtew, Takele (Addis Ababa University, 2017-09)
    This thesis provides an overview of harmonic functions of the following topic a) Some basic results like, Maximum principle, uniqueness Theorem and Green’s Formula. b) The fundamental properties of harmonic functions, ...
  • kebede, Basazenew (Addis Ababa University, 2018-08-03)
    In this paper we study Bessel differential equation of the form ���������� + ������ + (���� − ����)�� = 0, and the modified Bessel equation of the form ���������� + ������ − (���� + ����)�� = 0 Along with the corresponding ...
  • Worku, Habtamu (Addis Ababa University, 2013-02)
    Combinatorics on words has imposed itself as a powerful tool for the study of large number of discrete, linear, non-commutative objects. This report is intended to discuss words, in particular,Christoffel words
  • Alemye, Gashaw (Addis Ababa University, 2017-10-05)
    This Project is about the study of rst order necessary and su cient conditions for unconstrained cone d.c. programming problems where the underlined space is partially ordered with respect to a cone.These conditions are ...
  • Woudaj, Hailemichael (Addis Ababa University, 2011-01)
    In this paper, we will observe how to find the spanning trees of a graph and the methods that we use to calculate. The methods that we use for calculating the spanning tree of the graph are deletion and contraction, matrix ...
  • Atikaw, Sebsibew (Addis Ababa University, 2016-06)
    . This thesis discusses the relationship between Bernstein-Sato ideals of = xy(a3x + y):::(amx + y); ai 2 C; ai 6= aj ;m _ 3 and the decomposition of the D2-module M_ Chx; y; @x; @yi___ over the Weyl algebra Chx; y; ...
  • Girma, Bizuneh (Addis Ababa University, 2012-11)
    This project contains two parts; theory of distribution and Sobolev spaces. In this project, we discussed theory of distribution and also the differentiations of distribution, multiplication by smooth function of distribution, ...
  • Araya, Ataklti (Addis Ababa University, 2017-06-28)
    In this thesis, we investigate entire solutions of the quasilinear equation (y) __u = h(x; u) where __u := div(_(jruj)ru): Under suitable assumptions on the right-hand side we will show the existence of in_nitely many ...
