    Design and Implementation of a Web Based E-Iearning Support System (For Technical and Vocational Education and Training (TVET)
    (Addis Ababa, Ethiopia, 2013-08) Hailemariam, Dawit; Midekso, Dida (PhD)
    Outcome based TvET training is important in laday's development of the economic sector. Young people and technologies should be rcady for a country to fit in the dynamically complex learning/training and working envi ronment. The case of Ethiopia is no exception, The country has been in a steady growth in TYET train ing since its implementat ion in 2001 /02. Compared 10 other deve loped co untries TYE'!' training in Ethiopia has not yel rcached the required level of developmen t. This impl ies more work should be carried oul 10 Ill eet present and future needs of ski lled and well tra ined man power as per the need or the variolls training and education fields and the req uirement of the labor market. The purpose of this work was to conduct a sllldy on design and im plementation or a web based eLearn ing support system ror TVET training programs. System requirements have been rigorously collected rrom the fi ve TVET institutions in Addis Ababa; and consulting related literatures and soft ware products which are used in other countries has been made. The design and implementat ion or a prototype system was done in accordance with the ident ified runctional and non runctional req uirements. The prototype has been tested with data from the li ve TVET institutes in Addis Ababa. II has been fOllnd out that the system enables the trainers and tra inees to register, to download proper learn ing material s, to obtain recent in formation about the TVET training, to see result (progress chart) ror a unit or competency, to send noti fi cation by mobile, to download and submit ass ignment, to download teachers guide, curriculum, TVET strategy documents, and generate various reports.

    Study on Local Steel Profiles in Steel Concrete Composite Bridges
    (Addis Ababa University, 2009-08) Hailemariam, Dawit; Adamu, Asnake(PhD)
    Building a functional transportation infrastructure is a high priority for a nation, particularly for developing country like ours. Currently, the Ethiopian government has given special attention for road construction sector and is to invest billions of dollars. Parallel to road construction, there is also a demand of construction of bridges as most of the existing ones are getting older as they are constructed, during colonization by Italians. Construction of such bridges naturally occupy longer construction time where the time required may be farther exacerbated due to shortage of budget beside having bad construction management practice which is observed in many construction undertakings. Associated with this, the normal day to day traffic flow is affected and causes discomforts to the road users. This problem is serious especially in towns where there is high traffic volume and provision of detours is not simple. Thus, as alternate, steel-concrete composite bridge which obviously shortens the construction time and alleviates the problems with other added advantages is thought in this study. Therefore, in this thesis attempt is being made to compare the usage of locally produced steel profile in steel-concrete composite bridges with the conventional reinforced concrete deck girder bridges cost wise, beside evaluating other merits of such application. In the thesis work, relevant literatures are reviewed, assessment of availability of local steel profiles for such application has been made to local private and governmental companies that are engaged in manufacturing, supplying and installing of such steel profiles for different engineering purposes. Kality Metal Products Factory, Mesfin Industrial Engineering PLC and Maru Metal Industry are among some whose local products are considered. Accordingly, it is observed that there is local capacity and experience of manufacturing I-section profiles by
