  • Duality, Fenchel (Addis Ababa University, 2015-10)
    On this project we will see Fenchel Duality.If the function is convex and dier- entiable every where,then we can nd the minimizer by setting the derivative to zero. If the function is convex but not dierentiable, then ...
  • Abuto, Chakiso (Addis Ababa University, 2011-06-21)
    We present in this report the methods that provide better upper bounds for the number ) of permutations of length n avoiding the pattern q. We consider permutations that avoid the pattern q of length three, four and ...
  • Geletaw, Shemels (Addis Ababa University, 2016-06)
    Penalty and augmented Lagrangian methods are procedures for approximating constrained optimization problems by unconstrained optimization problems to and the approximate so- lution of the given constrained problem. The ...
  • Bayafers, Habtu (Addis Ababa University, 2014-08)
    The main objective of the present Project is to address how to set axioms to establish a perpendicularity relation in Abelian Group and then study the existence of perpendicularity in(Zn; +) and (Q+; :) in certain other ...
  • Moges, Eshetu (Addis Ababa University, 2015-03)
    Gelada is the only survivor of the genus Theropithecus, which once included several successful extinct species that lived in Africa and Asia. The wild populations of gelada are now restricted only to the Ethiopian plateau. ...
  • Kebede, Chehos (Addis Ababa University, 2015-07)
    The main purpose of this study was to assess the practices and challenges of mathematics teachers in conducing Action research in Governmental Secondary Schools of Addis Ababa city Administration. A descriptive survey ...
  • Asrat, Belew (Addis Ababa University, 2017-08)
    Malaria is one of the leading causes of illness and death in Ethiopia. Over the past years, the disease has been reported as the first leading cause of outpatient visits, hospitalization and death in health facilities ...
  • Tsegaberhan, Heanok (Addis Ababa University, 2016-01)
    From an algebraic point of view, semirings provide the most natural gener- alizations of the theory of rings. In this paper, the ring theoretic results of concerning the primary ideals and their radicals to noncommutative ...
  • Abebe, Tsegaye (Addis Ababa University, 2013-03)
    Measure Theory is the rigorous mathematical study of the field commonlyknown as Hausdorff measure.Hausdorff measures were introduced as certain lower dimensional measures on ℜwhich allow us to measure “small” subsets in ...
  • Kebede, Meresa (Addis Ababa University, 2011-06)
    In this paper we sketch the connection of Boolean algebra and Boolean rings and concept of Boolean near rings with identity to construct a class of Boolean near rings called special Boolean near ring for which it fails to ...
  • Gizaw, Dejene (Addis Ababa University, 2014-06)
    In this project work a smooth parametric nonlinear optimization problems subject to equality and inequality constraints are considered. Emphasis is given on those conditions under which the optimal solutions are di_erentiable ...
  • Asfaw, Amsalu (Addis Ababa University, 2014-02-27)
    Ramsey Theory is named after Frank Plumpton Ramsey a young man was especially interested in logical and philosophy. Ramsey died at the age of 26 in 1930 the same year that his paper on a problem of formal logic was ...
  • Weldegiorgis, Aregawi (Addis Ababa University, 2011-01)
    Algebraic Geometry can be used to prove geometric theorems in Euclidean Plane Geometry. This can be done when the geometric theorem has the property that the hypothesis and the conclusion of the theorem can be translated ...
  • 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, ...
