Dealing with Quality-of-service (QoS) routing in a mobile Ad-Hoc network is difficult due to the fact that the network topology changes constantly and the available link state information for routing is naturally indefinite. QoS related with band width utilization is very interesting because band...
The Amhara regional state is highly affected by land degradation through soil erosion, to reverse the severity of the problem, soil and water conservation practice were introduced in different parts of the region including the study area. Even though a number of soil and water conservation methods...
This paper presents the nature of the links between economic growth, poverty and incomerndistribution, a central question to the study of economic development. The model adapted wasrnthe simple non-dynamic Computable General Equilibrium (CGE) model developed byrnInternational Food Policy Research...

Photovoltaic device based on blend of alternating polyrnuorene green-6 (APFO Green-rn6) and [6,6]-phenyl C61-butyric acid methyl ester(PCBM) in a sandwich structure ofrnITO/PEDOT-PSS/APFO Green-6:PCBM/Al was fabricated. The device was characterizedrnby analyzing the current density-voltage...
The physics of strongly correlated electronic systems has attracted much attentionrnbecause of its unique and distinct properties like Mott metal-to-insulator transition,rngiant magneto-resistance, superconductivity. While the density functional theoryrn(DFT), the standard approach to electronic...
Members of the Family Suidae (Artiodactyla, Mammalia) are among the most studied in the Plio-Pleistocene vertebrate fossil record of Africa. However, a number of disagreements remain in terms of their taxonomy and phylogenetic relationships. There were also some disagreements in relation to the...
The earthquake hazard in an area depends mainly on three factors: - 1) The Regionalrnearthquake sources and seismic wave propagation characteristics, 2) The local geology’srnresponse to, and modification of, Earth- quake ground shaking and 3) Type and use ofrnbuildings and life lines...
Lake Awassa is located in the central main Ethiopian rift valley. The Lake is importantrnwater resource in the study area and is used for irrigation, municipal and domestic waterrnsupplies as well as recreational purposes. Beside its importance, the level of the lake hasrnchanged dramatically over...
Expansive soils are characterized by volume change due to variation in moisture content. Therncyclic wetting and drying processes causes vertical movements in expansive soils and thesernmovements lead to failure of pavements. These soils have very low load bearing capacity toornwhen wet. These...
Climate has always been a dynamic entity affecting natural systems through the consequence ofrnits variability and change. Agriculture is the most vulnerable and sensitive sector that is seriouslyrnaffected by the impact of climate variability and change, which is usually manifested...
This thesis deals with the structure of relative clause in Silt'i. The work isrnmore of descriptive than theoretical; however, some aspects of the properties ofrnrelative clause of Silt'i have been analyzed in terms of the theoreticalrnassumptions of the Principles and Parameters theory (Government...
Solid waste management system is the most difficult task that many countries, both developingrnand developed, are facing. Landfill method is one of the easy and cheap management systemsrnwhich are always needed for sustainable management of solid waste. However, if not sited andrnmanaged properly,...
