(PhD Thesis;2015:83, Doctoral thesis, 2018-05-03)It has been noted that any hope for transformation in education lies in the hands of the teacher and/or teacher educator who inevitably must take on the role as implementer of policy innovation. It is, however, not only ... -
Analysis of land use / land cover change dynamics and underlying driving forces in the Lake Hawassa Watershed, Ethiopia, based on satellite remote sensing, GIS and field investigations
(PhD Thesis;2015:89, Doctoral thesis, 2020-11-04)Lake Hawassa Watershed, in the Central Rift Valley, is one of the most environmentally vulnerable areas in Ethiopia. The rapidly increasing population and vegetation clearance in search of farming and grazing land, firewood, ... -
Assessment of machine learning methods for automatic tumor segmentation
(PhD Thesis;2023:12, Doctoral thesis, 2023)The definition of target volumes and organs at risk (OARs) is a critical part of radiotherapy planning. In routine practice, this is typically done manually by clinical experts who contour the structures in medical images ... -
Biodiesel production from Jatropha curcas L. seeds from different agro-climatic zones of Ethiopia: seed processing, oil extraction and optimization of biodiesel production using heterogenous catalysts
(PhD Thesis;2020:66, Doctoral thesis, 2020)Energy is basic for development and its demand increases due to population growth, urbanization, and the improvement of living standards in most parts of the world. Nowadays, the energy sector faces dual challenges, the ... -
Biofuel production potential of Jatropha curcas L: oil characterization for biodiesel production, and enhancing the biogas production potential of various residues using different pretreatment methods
(PhD Thesis;2021:21, Doctoral thesis, 2021)Increasing global fuel prices, growing energy consumption, and profound environmental concerns are the key factors that motivated the search for alternative energy sources. Biofuels such as bioethanol, biodiesel, and biogas ... -
