Performance Characteristics Of Blended Rice Bran Biodiesel In A Diesel Engine
(2013)
Rice bran is a by-product of the rice milling process and contains 10–25% oil depending on rice variety, milling procedure, and other agro-climatic factors. To supplement the dwindling fossil fuel reservoirs and reduce ...
Energy Dispersive X-Ray Fluorescence (EDXRF) in Non-Destructive Testing of Oil Samples
(2013-08-01)
A rapid non-destructive, multi-elemental and ultra-sensitive analytical technique of engine oil analysis is described. Using" an x-ray excitation source and Si(Li) detector for the1 measurements, the deterioration of an ...
Fundamentals of Photogrammetry
(2013)
Like in many other disciplines, there is no universally accepted definition of the term photogrammetry. The Manual of Photogrammetry (2003) defines photogrammetry as the art, science, and technology of obtaining reliable ...
Water Resources
(2013)
Fresh water is one of the basic necessities without which human beings cannot survive since water is key to the sustainability of all kinds of lifeforms. Water has multiple uses namely; nutritional, domestic, recreational, ...
Optical Remote Sensing
(2013)
There are a large variety of systems for collecting remotely sensed data in operation today.
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
