An Intrinsic Dislocation Density – Finite Element Formulation Of Metal Plasticity
(2012)
A computational model was developed to simulate elastic and plastic behavior in Body Centered Cubic (BCC) metals and
alloys. The model provided for simultaneous simulation of the micro and macro length scales and used ...
Joint queue-perturbed and weakly coupled power control for wireless backbone networks
(2012)
Wireless Backbone Networks (WBNs) equipped with Multi-Radio Multi-Channel (MRMC) configurations do experience power control problems such as the inter-channel and co-channel interference, high energy consumption at multiple ...
Application of Decision Theory and Information Processing in the Selection of Engineering Entities
(University of Nairobi, 2012)
The selection of engineering entities often occurs in engineering design
processes. Examples of such occurrences are the selection of antifriction
bearings, belt drive components, chain drive components and wire rope, ...
Viscoelastic Properties of Bulk Groundnuts
(2012)
The groundnut, Arachis hypogaea Linn, samples were collected from the majorly grown areas of western Kenya to investigate the viscoelastic properties pertinent to grain handling, storage and processing. In particular, the ...
Electrolytic Etching of Platinum- Aluminium Based Alloys
(2012)
The microstructures of as-cast and annealed platinum alloys of different compositions were revealed after electrolytic etching in hydrochloric acid/sodium chloride solution using direct current. It was shown that the etching ...
An Experimental Prototype For Low Head Small Hydro Power Generation Using Hydram
(2012)
The global rise in energy demand has resulted to the over exploitation of both renewable and non renewable energy sources. Most feasible hydroelectric power (HEP) plants sites have been exploited and the current focus ...
Reducing real and reactive power losses in the distribution system by DFIG placement and sizing using ordinary PSO and HGPSO : a comparison
(University of Nairobi, 2012)
Due to the increased importance of DFIGs in optimization of real and reactive power losses and the maintenance of voltage profile, the general methods of DG placement and sizing in the existing literature cannot be of ...
Tectonic structures across the East African rift likely to pose the greatest earthquake hazard in Kenya.
(University of Nairobi, 2012)
Over the last 5-10 years, there has been accelerated geothermal resources development for geothermal power generation in order to meet the country’s electricity demands and hence make Vision 2030 feasible. However, owing ...
Optimising Voltage Profile Of Distribution Networks With Distributed Generation
(2012)
Power utility companies are required to supply
customers with power within specified voltage limits. Voltage
rise in networks with distributed generators therefore poses a
challenge. This paper presents a coordinated ...
