This thesis focuses on the determinants of foreign direct investment inflows to Ethiopia. In an attempt to attract Foreign Direct Investment (FDI), most countries have liberalized trade and attempted to create enabling environment in recent decades. Ethiopia, like many African countries, took some...
Road traffic accident is becoming the major problem globally. Our country is also facing the problem currently with increasing trend of the magnitude of the problem from time to time. Addis Ababa, the capital of the nation is the major area where traffic accident is occurring in the country. One of...

People spend a considerable time in vehicles; cars, trains, planes, buses or subway. This is the reason why the thermal comfort has more and more paid attention. In one hand people try to make comfort whatever they are at home, office or in car. In the other hand the thermal conditions in the cabin...
The goal of this study is analyzing and identifying the stresses on bolted rail joint due to thernwheel load to predict and minimize failures caused. The three dimensional model has beenrndeveloped on modeling package of CATIAV5R16. In CATIAV5R16, different components ofrnwheel/rail assembly i.e....
The modeling of thermal and mechanical effects during braking has become increasinglyrnimportant in product design in different transport means, road vehicles, airplanes, railwayrnvehicles, and so forth. The thermal and mechanical analysis is a very important stage in thernstudy of braking systems,...
Optimization of sesame oil extraction using response surface methodology (RSM) was carried out in this study. The effects of three factors (moisture content of seed, extraction temperature and extraction time) on the oil yield obtained from the seed were considered. With the aid of Design Expert...
Groundwater is essential resource which used in many aspects of life activities. Ethiopia has abundant potential of groundwater resource and in resent two decades the development of this project is increased. Addis Ababa water demand highly increases due to fast population growth, urbanization and...
Electrical energy plays a vital role almost everywhere, especially those that are energyrnintensive institutions. As there are limited resources and increased cost to generaternelectricity, it is our keen duty to save resources for future use by doing research aboutrnenergy conservation, which...
This thesis presents design and comparative analysis of fractional order PI controller, integer order PI controller and an adaptive neurofuzzy controller trained by input output data from fractional order PI controller for indirect vector controlled induction motor. The parameters of the two PI...
Textile sludge is an inevitable byproduct discharged from wastewater treatment plants and becoming a great challenge in today’s industrial parks. Presently, the sludge generated from the ZLD facility is sent and collected inside nearby big constructed shed without any treatment. Since, the...
This study focused on treatment technique using peanut hull to produce natural adsorbent for softening the tap water in Mekelle city which is hard water. Its physicochemical properties were examined. Water softening experiments were conducted to observe the changes in hardness causing Ca2+ and Mg2+...
Improving the performance of medical equipment supply chain management system is crucial in the healthcare service delivery. The Pharmaceuticals Fund and Supply Agency (PFSA), the responsible body, has strived to systematize the medical equipment supply chain management system (MESCMS) since its...
The waste-to-energy conversion processes are expected to play an increasing important role in sustainable management of solid waste. The primary function of waste-to-energy technology has been volume reduction and power production.rnWaste management has become a critical issue as solid waste...
Today Mojo has expanded considerably with new buildings, railways, roads, industriesand dry port. Therefore, a better understanding of the subsoil is required. It is also worthmentioning that, Mojo is located in the rift valley of Ethiopia thus placing it in seismic activzone. According to EBCS 8,...
Poor land use practices and improper management systems have played a significant role in causing high soil erosion rates, sediment transport and loss of agricultural nutrients in Gidabo sub basin. This serious problem can also play great role on the silting up of reservoirs and shortening their...
Significant traffic and congestion across urban areas, as well as waterways, create a demand for long-span bridges. The construction of these longer spans plays a critical role in the development of modern infrastructure due to safety, environmental, and economic reasons. A variety of bridge...
This thesis report presents traction power consumption analysis on the existing Ethio-Djibouti electrified railway network, particularly along Awash~Sirba Kunkur~Sebaka Line Subsection. The result of the analysis is recommendation of possible freight train operational speed in the line subsection...
Delay is generally acknowledged as the most common, costly, complex and risky problemrnencountered in construction projects. Because of overriding importance of time for bothrnthe owner (in terms of performance) and the contractor (in terms of money), it is thernsource of frequent disputes and...
The purpose of this thesis is to develop an automatic railway gate system that uses the FPGA as a main function of design. The principle objective of this thesis was to design an automatic railway gate control by FPGA. This thesis deals to develop a prototype of railway gate that function...
