Data Models and Structure
(2013)
By convention, data in the real world is deemed to exist in a continuous or analogue form usually in three dimensional space as discussed in Sect. 2.1. Such data needs to be digitized or made discrete before it can be input ...
A Combined Sensitivity Factor Based GA-IPSO Approach For System Loss Reduction And Voltage Profile Enhancement
(University of Nairobi, 2013)
Though several algorithms for optimizing DG location and size in a network with the aim of reducing system power losses and enhancing better voltage profile have already been proposed, they still suffer from several ...
Effects of Distributed Generation penetration on system power losses and voltage profiles
(University of Nairobi, 2013)
In present times, the use of DG systems in large amounts in different power distribution systems has become very popular and is growing on with fast speed. Although it is considered that DG reduces losses and improves ...
Partial Replacement Of Natural River Sand With Crushed Rock Sand In Concrete Production
(University of Nairobi,, 2013)
The use of crushed rock sand as a partial replacement of river sand in concrete production was
investigated. Water cement ratio varied between 0.55
and 0.59 for 0
% to 100
% natural sand
replacement. The slump ranged ...
Large herbivores maintain a two-phase herbaceous vegetation mosaic in a semi-arid savanna.
(University of Nairobi, 2019)
Many arid and semi-arid rangelands exhibit distinct spatial patterning of vegetated and bare soil-dominated patches. The latter potentially represent a grazing-induced, degraded ecosystem state, but could also arise via ...
