Rain cell sizing for the design of high capacity radio link systems in South Africa
(2011)
This paper investigates the influence of critical raindrop diameters on the specific rain attenuation in Durban (29°52'S, 30°58'E), South Africa. The total rainfall attenuation is evaluated by integrating over all the ...
Improved spatial prediction of soil properties and soil types combining semi-automated landform classification, geostatistics and mixed effect modelling
(2011)
Landforms classifications using a range of techniques
from pure automatic classification to hybrid semiautomated
model / expert opinion was tested as a base for a
robust modelling of soil characteristics spatial ...
Microwave Path Survey Using Differential GPS
(Maney Publishing, 2011)
A microwave path survey is critical before any wireless communication infrastructure can be put into place. It is on the basis of this that the line of sight possibility between any pair of stations is established. This ...
Optimal placement of a piezoelectric ring in an ultrasonic powder transport system
(2011)
The transport of powder materials is an important aspect of process engineering. Various industries such as the food, chemical, pharmaceutical, coating, information and telecommunication industries have set a high demand ...
The role of architecture in Kenya Vision 2030; a case of University of Nairobi
(2011)
This paper develops two lines of thought about how the discipline and profession of architecture can
become critical players in the delivery of Vision 2030 in Kenya. The first dimension argues for the
recognition of ...
Path reduction factor modelling for terrestrial links based on rain cell growth
(2011)
A new path length reduction factor that accounts for the growth and occurrence of multiple rain cells along a propagation path of a given terrestrial link is introduced in this work. In addition, the mathematical and ...
Merging Indigenous African and Western Knowledge Systems; I
(2011)
Since colonial times, Euro centricism has eroded development and modernization of not only indigenous
African architectural design values but also other Sub-Saharan, socio-cultural heritage knowledge and
practices. From ...
