(2018-08)
Fifth generation wireless communication networks will demand massive bandwidth for high data rates. The millimeter wave frequency bands will play an important role in the 5G wireless networks due to the available huge chunk ...
The ‘romance’ of mining in light of tourism: A case study of soapstone in Tabaka, Kisii County, Kenya
(Association for Tourism and Leisure Education, 2015)
Mineral products are at the core of today’s civilized world that we live in. The manufacturing sector, the high technology industries and even the resource industries are all dependent, in one way or the other on the mining ...
Profit based unit commitment in deregulated electricity markets using a hybrid lagrangian relaxation - particle swarm optimization approach
(2017)
In deregulated electricity markets, individual generation companies (GENCOs) carry out independent unit commitment based on predicted energy and revenue prices. The GENCOs unit commitment strategies are developed with the ...
Review of policies and frameworks on climate change, agriculture, food and nutrition security in Uganda
(2020-08)
Uganda is facing climate variability and change more frequently than ever. This is observed through changing temperature patterns—often linked to more frequent and longer periods of drought spells that lead to significant ...
Efficient Control strategy based on instantaneous power theory and model predictive control for grid connected photovoltaic system
(2021-11)
Due to the rapid decline of fossil resources and the impact of their use for electric power generation on the environment, renewable energy sources are increasingly explored and integrated into the power grid. Among the ...
