A computational methodology for simulating quasi-brittle fracture problems
(Elsevier: Computers & Structures, 2019-04-15)
The paper focuses on an efficient and simple methodologies for simulating the three dimensional (3D) quasi-brittle fracture problems. Strain-softening is performed on the elements by a developed anisotropic continuum damage ...
Stakeholder participation and service quality of road construction projects in local governments: a case of Adjumani district urban and community roads division
(Kyambogo University, 2021-04)
The study investigated the effect of Stakeholder Participation on Service Quality in Local Governments in Uganda. The objectives of the study were; to examine the effect of information sharing on service quality of road ...
Effect of banana fibers on the mechanical and microstructural properties of concrete
(Kyambogo university (unpublished work), 2021-08)
This research presents an experimental study on the "Effect of Banana fibres on the
mechanical and microstructural properties of concrete". Concrete being a quasi-brittle
material, exhibits limited ability to restrict ...
Identification and punishment policies for spectrum sensing data falsification attackers using delivery-based assessment
(IEEE Transactions on Vehicular Technology ., 2015-11)
Spectrum sensing data falsification (SSDF) attacks represent a major challenge for cooperative spectrum sensing (CSS) in cognitive radio (CR) networks. In an SSDF attack, a malicious user or many malicious users send false ...
Investigation of cracks in flexible pavement on a section of Kampala – Masaka road
(Kyambogo University [unpublished work], 2022-11)
The study investigated cracks in flexible pavement on a section of Kampala-Masaka Road. The continuous occurrence of cracks which has affected the riding quality, increase in travel times as the vehicles be moving at a ...
Coated tools with crater‐like surface structures have enhanced performance
(AIP Conference Proceedings, 2010-10-18)
This paper presents the result of an investigation into the cutting characteristics of electrical discharge machined (EDMed) surface‐modified carbide cutting tool inserts. The tool inserts were coated with Titanium Nitride ...
African food insecurity in a changing climate: the roles of science and policy
(Wiley Online Library: Food and Energy Security, 2018-12-12)
African population is projected to double to 2.48 billion people by 2050. The population increase poses a serious challenge of increasing food supply to meet the future demand. This challenge is compounded by climate change ...
Dynamically dimensioned search embedded with piecewise opposition-based learning for global optimization
(2019-05-26)
Dynamically dimensioned search (DDS) is a well-known optimization algorithm in the field of single solution-based heuristic global search algorithms. Its successful application in the calibration of watershed environmental ...
Quantitative analysis of contributions of human activities and climatic variability to stream flow variation in river Rwizi catchment
(Kyambogo University, 2021-08)
Climate variability and human activities have an impact on hydrological processes. Human activities influence rainfall runoff generation process while climate variability does not only affect runoff volume but also low and ...
Hydrological model supported by a step-wise calibration against sub-flows and validation of extreme flow events
(MDPI, 2019-01-31)
Most hydrological models have fixed structures and their calibrations are typified by a conventional approach in which the overall water balance closure is considered (without a step-wise focus on sub-flows’ variation). ...
