Distress Features Of Flexible Road Pavement In Kenya
(1982)The direct use of pavement design methods, generally originating from Europe, in tropical countries such as Africa has in several cases led to premature pavement failure so causing unplanned expenditure in the repair of ... -
Mechanical properties of granular materials as related to loads in cylindrical grain silos
(1987)Physical quantities thought to be pertinent to the development of loads in cylindrical silos filled with granular materials were identified. The principles of similitude and dimensional analysis were used to formulate, ... -
Nairobi solid waste management practices: Need for improved public participation and involvement
(2010)In the globalized world, the current focus in municipal waste management is on the development of sustainable and integrated waste management system, where the central role would be played by the public through effective ... -
Friction coefficient of cereal grains on various surfaces
(1990)The static coeff. of friction of 3 materials which could be used in the construction of silos were determined for oats and shelled maize at different m.c. within a range of 10-20% (w.b.). In general, the coeff. increased ... -
Status Of ILabs In Sub-Sahara Africa (iLabs-Africa)
(Electrical and Information Engineering, University of Nairobi, 2009) -
A Model Hardness for Heat-Affected Zone Profiles in AI-Li-X Alloys
(1998)A model based on reaction kinetics and elemental diffusion is proposed to account for the presence of double inflection in the hardness profiles of the heat-affected zone (HAZ) in weldments of AI-Li-X alloys tested ... -
Designing Cavity–Backed Slot Antenna Array: A Numerical Implementation Using ADI-FDTD Method
(Electrical and Information Engineering, University of Nairobi, 2012) -
Electrolytic Etching of Platinum- Aluminium Based Alloys
(2012)The microstructures of as-cast and annealed platinum alloys of different compositions were revealed after electrolytic etching in hydrochloric acid/sodium chloride solution using direct current. It was shown that the etching ... -
Distribution Of Electromagnetic Field Radiation From A Rectangular Cavity-Backed Slot Antenna, ADI-FDTD Perspective
(Electrical and Information Engineering, University of Nairobi, 2012) -
Effect of runner design on mechanical properties of permanent mould aluminium castings
(2006)A comparison of the influence of different runner designs on the mechanical properties of aluminium castings has shown that filtered rectangular runners (FRRs) yield aluminium castings with higher and more reliable mechanical ... -
A model for heat-affected zone hardness profiles in Al-Li-X alloys
(1998)A model based on reaction kinetics and elemental diffusion is proposed to account for the presence of double inflection in the hardness profiles of the heat-affected zone (HAZ) in weldments of Al-Li-X alloys tested without ... -
Geometric constants in plain cross-bored cylinders
(Dept. of Mech. Eng., University of Nairobi, Kenya, 2003)A three-dimensional FEM computer program was developed to establish the stress distributions and SCFs in thick walled cylinders with flush and nonprotruding plain cross bores under internal pressure. The displacement ... -
A Model for HAZ Hardness Profiles in AI-Li-X Alloys: Application to the AI-Li-Cu Alloy 2095
(1998)In a previous paper (Ref. 1), details were presented of a theoretical model describing the evolution of the hardness profiles in the heat-affected zones (HAZ) of AI-Li-X weldments. The intent of the model was to ... -
On deviated and branched crack paths in AlLiX alloys
(1996)The origins of deviated and/or branched fatigue crack paths in Alsingle bondLisingle bondX type alloys were investigated. The crack paths were predicted by calculating the orientation of the slip planes in single crystals ... -
The effect of welding on the fatigue crack growth rate in a structural steel
(1993)Fracture mechanics principles have been used to study the effects of welding on the rate of fatigue crack growth (FCG) in a low-carbon structural steel. The steel concerned is used widely in the fabrication of the ... -
Patterns of Aerial Triangulation by Independent Models
(Department of Geospatial and Space Technology, University of Nairobi, Kenya, 1992)The position of the non-zero elements in the coefficient matrix of the reduced normal equations are directly defined based on the existence of tie points between the models. The shape and the size of the matrix and the ... -
Monitoring recent crustal movements in the Kenya rift valley by global positioning system (GPS)—a proposal
(Department of Geospatial and Space Technology, University of Nairobi, Kenya, 1991)There is evidence that the Kenya Rift is active. 1990 witnessed the execution of the Kenya Rift International Seismic Project to study the deep structure of the Kenya Rift. Yet there is no actual measurement of the rate ... -
Stability of relative orientation
(1981)This paper investigates the effect of the deviation of measured points from the standard locations when carrying out a relative orientation of a stereomodel. The analytical solution of more than 100 cases was considered ...
