    EVALUATION OF PROPOSED EMBANKMENT DAM FOR DODOTA IRRIGATION PROJECT
    (Hawassa University, 2018-08-10) DAWUD MANZA DOLLEMO
    Design and construction of embankment dam is increasing from to time in our country to help the utilization of water for multipurpose. Evaluation of propose embankment dam for Dodota Irrigation project as alternative design by introducing asphaltic concrete core or clay core vital form the stand point of safety, controlling seepage and very important structure in fault and Earthquake area. This study was aimed to evaluate a proposed embankment dam as alternative design and analysis for Dodota Irrigation Project. Address this objective proposing an embankment dam with an impermeable asphalt concrete core and analyzes it for seepage static and dynamic stability using Geo Studio 2012 numerical computer program. Based on computation the flux through the dam and foundation for asphaltic concrete case has been found to be 0.000059 m 3 /s and the flux through the dam and foundation for asphaltic concrete case has been found to be 0. 0.001334 m 3 /s. The factory of safety of the propose embankment dam for the alternative design of embankment at different construction stage and with different loading condition satisfied the minimum requirement of (USAC,2003). The stress deformation observed was much lower than the expected bearing capacity of the foundation rock. The static deformation analysis computed for the propose embankment dam shows the horizontal and vertical deformation that the dam may subject to were in the tolerable limit. The dynamic deformation also analysis computed for the propose embankment dam during the time of shaking the maximum vertical and horizontal deformations within allowable limit. Generally, application of asphaltic concrete core rick fill and rock fill clay core dam in the project can fulfill the basic requirement and minimum factor of safety under all loading condition. Over all analysis of the thesis aim is indicate the possibility of constructing dam for the Dodota Irrigation Project

    DECISION FRAMEWORK FOR THE USAGE OF CLOUD TECHNOLOGY IN ETHIOPIA HIGHER EDUCATION INSTITUTIONS
    (Hawassa Unversity, 2019-10-06) SELAM DESALGNE
    The rapid technology advancements are always creating new opportunities and a new way of working. Cloud Technology is being popularizing across the world especially in academic institutions. It is not a new technology but rather a new delivery model for information and services using existing technologies. The paradigm has been recognized recently as key enabling efficient and effective technological services that will reshape the delivery and support of the educational services. This study is conducted on public Ethiopian Higher Educational Institutions to explore the critical determinants that influence the adoption of the Cloud Technology. Despite the fact that cloud computing offers great deal of opportunities, its adoption exacerbated with lack of standards and relative lack of general framework created dilemma for the institutions how to approach the cloud adoption. An exploratory study is carried out. This research work proposes TOETAD conceptual framework according to the Technology Organization Environment (TOE) model, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM) with added Decision Maker Context to the model. Adoption determinants for the technology will be examined through the lens of integrated model. The framework factors were identified by critically reviewing studies found in the literature together with factors from the industrial standards within the context of Ethiopia Higher Education Institutions. Data is collected by online questionnaire survey with IT managers, lectures, E-learning coordinators and Team Leaders from selected 17 Ethiopia Higher Educational Institutions with a total 103 respondent. On the other hand the proposed frame work is evaluated by an expert to validate the framework. The result also helps to encourage the Public Higher Educational Institutions in Ethiopia to understand the nature of the problem, increase their awareness about factors to be considered while adopting the cloud computing
