  • Game on Zero Sum 
    Haileslassie, Amha (Addis Ababa University, 2020-06-22)
    A game with two rational players in which the gain payo for one is loss for the other is called two person zero-sum game. i.e the sum of payo s for the two players are zero. Two person zero-sum game with nite sets of ...
  • Gamma Ray Attenuation In Composite Materials 
    Ahmed, Nuredin (Addis Ababa University, 2010-07)
    Attenuation due to scattering or absorbtion of photons in composite materials depend basically up on two factors, the effective atomic number and electronic density of the absorber material. This project discuses recent ...
  • Gamma Ray Production in an Accreting Neutron Stars 
    Reshid, Remudin (Addis Ababa University, 2007-07)
    Inverse compton (IC) scattering of lower frequency photons by relativistic electrons was used as a method for the production of high-energy gamma-rays in an accreting neutron stars. A spectrum function is derived.Based ...
  • Gamma-Ray Burst In Swift Era: Analysis of Afterglow Light Curves 
    Endalamaw, Deres (Addis Ababa University, 2017-10)
    We presented the temporal study of all swift/XRT observations of GRB afterglows discovered between January 2005 and July 2005 which they have two or more than two breaks and well known redshift. After constructing and ...
  • Gamma-Ray Spectroscopy 
    Teffera, Yohannes (Addis Ababa University, 2018-08-03)
    Gamma-ray spectroscopy is the chief experimental technique of atomic physics and studies the high energy photons which are characteristic of the specific initial- and final-state nuclear energy levels, from radioactive ...
  • Garlic and orange plant materials evaluation for the control of Sitophilus spp. (Coleoptera: Curculionidae) and Zabrotes subfasciatus (Coleoptera: Bruchidae) in Ethiopia. 
    Kidane, Dawit (Addis Ababa University, 2005-06)
    At present much emphasis is being placed in the use of botanical pesticide in the protection of storage insect pests, which have gradually been ignored and also to avoid problems with insecticide resistance. Experiments ...

  • Geez To Amharic Automatic Machine Translation: A Statistical Approach 
    Mulugeta, Dawit (Addis Ababa University, 2015-05-05)
    Machine Translation (MT) is the task of automatically translating a text from one natural language to another. MT is essential for many applications including multilingual information retrieval, speech to speech and others. ...
  • Geez to Amharic Machine Translation 
    Abel, Biruk (Addis Ababa University, 2018-05-05)
    Natural Language Processing (NLP) is defined as ways for computers to analyze, understand, and derive meaning from human language in a smart and useful way. Machine Translation (MT) is one of the applications of NLP. It ...
  • A General Approach for Amharic SPEECH-TO-TEXT Recognition 
    Melese, Michael (Addis Ababa University, 2009-10)
    In this paper, the researcher has tried to investigate the capability of exploring speech recognition technique for converting an Amharic speech to text taking native and non native speaker of the language Amharic. For ...
  • A Generalized Approach to Amharic Braille Recognition 
    Wendmu, Amanuel (Addis Ababa University, 2015-06-08)
    In 1825 Louis Braille invented the writing system braille which is the preferred means of written communication for blind people around the world. In Ethiopia, there has been a large production of Amharic braille documents ...
  • A Generalized Approach to Amharic Text-To-Speech (Tts) Synthesis System 
    Tafere, Alula (Addis Ababa University, 2010-07)
    A text-to-speech (TTS) synthesis converts natural language text into speech. However, written text of a language contains both standard words (SWs) and nonstandard words (NSWs) like numbers, abbreviations, synonyms, ...
  • A Generalized Approach to Optical Character Recognition (OCR) Amharic Texts 
    Meshesha, Million (Addis Ababa University, 2000-05)
    These days research in Optical Character Recognition is popular for its application potential in banks, post offices, insurance, and other governmental and non-governmental organizations. Other application areas include ...
  • Generalized Catalan Numbers 
    Aseressie, Eyerusalem (Addis Ababa University, 2014-06)
    Ballot problem was introduced in the late nineteen century to determine the probability of counting of votes when there are two candidates A and B such that A receives a votes, and B receives b votes with a > b. This ...
