(SAGE, 2022-03-31)
This paper converts the six reasons for inclusive development proposed by Gupta into a heuristic device for evaluation of inclusive development in road infrastructure projects in Nairobi. The Gupta Rationale entails six ...
Ensemble-based model selection for imbalanced data to investigate the contributing factors to multiple fatality road crashes in Ghana
(University of Nairobi, 2021-03)
The study aims to identify relevant variables to improve the prediction performance of the crash injury severity (CIS) classification model. Unfortunately, the CIS database is invariably characterized by the class imbalance. ...
Performance Characterization of 64-APSK Mapping Schemes for Uncoded Space-Time Labeling Diversity in Rician Fading Channels.
(Institute of Electrical and Electronics Engineers, 2021)
This paper investigates design of spectrally efficient nonlinear transmission scheme for uncoded space-time labeling diversity that is compatible with DVB-S2X standard. Designs are presented for 64-APSK constellation by ...
The Influence of Photography and Digital Art on Contemporary Art and Design in East Africa
(Africa Design Review Journal, 2022-06-27)
A photographer and an Afrofuturist digital artist Osborne Macharia comes up with his best ideas in a very creative way. He starts with a visual composition and then looks for an anecdote that might complement it. He is a ...
The Optimization of the Surface Roughness of Milled Polypropylene + 60wt.% Quarry Dust Composite Using the Taguchi Technique
(University of Nairobi, 2021)
This study is based on the optimization of the parameters that influence the computer numerical control (CNC) milling operation during the machining of polypropylene+60wt.% quarry dust composite. The input parameters studied ...
Effects of Friction Stir Welding on Microstructure and Mechanical Properties of Extruded Secondary Aluminum 6061 Alloy
(University of Nairobi, 2021)
Experiments were carried out to determine the effects of friction stir welding on microstructure and properties of recycled Aluminum 6061 alloy, whose alloy content varied from that of primary alloy. The alloy was processed ...
Spatial autocorrelation and hotspot analysis of natural radionuclides to study sediment transport
(University of Nairobi, 2023)
Tracking sediment movement is typically done with artificial radionuclides. However, this can be environmentally harmful and does not allow for sediment classification. Naturally occurring radionuclides are consequently ...
Building Information Modelling in Urbanising Kenya
(University of Nairobi, 2023)
With the largest economy is East and Central Africa, Kenya serves as a regional centre for banking, technology and infrastructure. In the last ten years Kenya has experienced strong growth and development, largely anchored ...
