Household Travel and Activity Diary: An East African Experience in Transport Survey Methodology
(2004)
Public and non-motorised transport facilities in urban centres in Africa are less than what is justified by the demand. This may be due to the way the urban transportation problem has been formulated and travel surveys ...

Textile concrete provides special architectural and permanent shuttering opportunities.
(2004)
High Performance Fibre Reinforced Cementitious Composites (HPFRCC) are characterized by a stress–strain response in tension that exhibits strain-hardening behaviour accompanied by propagation of multiple cracks. This process ...
Effect of environmental exposure on the microstructure of textile concrete.
(2008)
This paper presents the results of recent experimentation performed to study time-dependent changes in the mechanical performance of textile reinforced concrete (TRC) made with AR glass fibre and to specify the decisive ...
Conservation Tillage and Food production in Semiarid Tropics of Africa
(2004)
Before the arrival of European agricultural technology, technologies addressing the need for more efficient capture and utilisation of resources were being developed in Africa. Land invasions and displacements, the ...
A Non-invasive Registration Technique in Hip-joint Replacement Surgery Using Laser Radar Imaging
(2004)
In this paper, we present a 3D imaging technique for computer-assisted hip-joint replacement surgery. It is based on a high resolution laser radar which uses powerful picosecond laser pulses, generated from low-cost ...
Conservation tillage Equipment productivity quantified
(2004)
Every production practice, including conservation tillage, has positive or negative environmental consequences that may involve air, land, water, and/or the health and ecological status of wildlife. The negative impacts ...
Modelling Hydraulic Conductivity
(2001)
A simple analytic model is proposed which predicts the unsaturated hydraulic conductivity curves by using the moisture content-capillary head curve and the measured value of the hydraulic conductivity at saturation. It is ...
Modelling snowmelt in Thiba catchment in central Kenya
(2001)
We established, calibrated, and validated a distributed hydrological model for the Thiba catchment in central Kenya. In the 1990s the catchment experienced a sharp increase in the use of water for agriculture. This study ...
