Determination of stress characteristics at Connections of Welded Members using Finite Element Method
(2004)
Tubular members are used in various structural members. They have a pleasant effect and good aesthetic values. They can be used in large roof structures, offshore rigs, pressure vessels, etc. The connection between tubular ...
Computer Simulation of Orthokinetic Flocculation in a Filterbed
(2004)
The rational for application of direct filtration in water treatment with omission of the conventional coagulation processes has been a subject of discussion since the inception of direct filters. Among the questions asked ...
A Local Approach Methodology for the Analysis of Uncracked Tubular Joints.
(2004)
In this study, the finite element method (FEM) is applied on a welded tubular T-joint, in order to analyse stress distribution in the vicinity of the weld fillet. The weld has been modelled all around the joint. A notch ...
Integrated water, energy and sanitation solution for stand alone settlements
(2005)
Lake Victoria basin has a large rural and rapidly growing peri-urban population that lacks sustainable solutions to safe and adequate water supply, energy and sanitation. Access to safe water and sanitation was 60% and ...
Towards a rainwater model village
(2004)
Poor availability of water and pastures has been identified as the single most important factor constraining productivity of livestock in Tanzania. Many smallholder livestock keepers have responded to the problem of shortage ...
Impacts of Rain Water Harvesting in Kusa
(2005)
Annual seasonal droughts of 2-4 months occur in Kusa limiting access of households to safe drinking water. This compounds the health and socio-economic disasters through increased water borne diseases rated at 10% morbidity ...
Performance of Crushed Coconut Shell Dual Media Filter Paper.
(2004)
The high cost of conventional building materials is a major factor affecting housing delivery in Nigeria. This has necessitated research into alternative materials of construction. This paper presents the results of an ...
Evaluation of toughness of textile concrete:
(2009)
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 ...
Proposes Log-MAP and SOVA based timing recovery methods in wireless channels.
(2006)
The radio interface EDGE (Enhanced Data rates for Global Evolution) is currently being standardized as an evolutionary path from GSM and TDMA-IS136 for third-generation high-speed data wireless systems. For the EDGE system ...
