  • 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. ...
  • Tigabu, Dereje (Addis Ababa University, 2016-07-04)
    Model predictive control is a form of control in which the current control action is obtained by solving on-line, at each sampling instant, a _nite horizon optimal control problem, using the current state of the plant ...
  • Alemu, Seyome (Addis Ababa University, 2015-10-01)
    This project deals with distributional solutions y(x) =∑ an (n) (x) n=0 of the conuent hypergeometric di_erential equation.Such di_erential equations also have solutions of the form 1F1(p;m; x) = 1 +∑ (p)nxn ...
  • Yadeta, Chala (Addis Ababa University, 2016-08)
    Study of the diversity and relative abundance of birds was conducted from October 2015 to April 2016 in Berek Forest, near Sendafa town of Oromia special Zone, Berek Woreda,Central Ethiopia, using the Timed Species Count ...
  • W/Yohannes, Dereje (Addis Ababa University, 2006-06)
    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 ...
  • Kidane, Tsega (Addis Ababa University, 2014-06-30)
    In this project we see about the duality in multiobjective programming. We investigate a general convex multiobjective optimization problem with cone inequality constraints. The main idea of constructing the multiobjective ...
  • Fita, Adugna (Addis Ababa University, 2012-01)
    Nowadays, human beings have been confronted with multiple criteria decision making problems. We want to have a good life, which may mean more wealth, more power, more respect and more time for our selves, together with a ...
  • Hailu, Tafesse (Addis Ababa University, 2014-06)
    In this project we present investigation of the linear wave equation with the unknown function u, subject to prescribed initial and/or boundary data, where Δ is n-dimensional Laplacian. In 1d, the solution of IVP is ...
  • Demessie, Eshetu (Addis Ababa University, 2013-02)
    A subset A of a Banach space X is called weakly sequentially compact if every sequence in A has a weak cluster point in X. The di_culty implication of the Eberlein- _ Smulian theorem states that such a set is already ...
  • Getachew, Dejene (Addis Ababa University, 2017-05)
    Malaria is a leading public health problem in Ethiopia. Though malaria prevalence showed high reduction in many parts of the country, its transmission is likely to be more and more focal with some areas still having ...
