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 ...
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 ...
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 ...
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). ...
Determination of cooling effects on tensile strength of re-bars using spray quenching
(Kyambogo University (un published work), 2019-08)
In this study, the tensile strength in carbon steel was achieved under controlled heating and cooling processes. Forty-five samples of billets were used to produce 12 mm, 16 mm and 20 mm of hot-rolled rebar and each rebar ...
Investigations into the mechanical performance of Ugandan made carbon steel bars
(Kyambogo University (un published work), 2019-08)
Carbon steel bars are one of the most used steel products in structural constructions worldwide. Ugandan steels have been reported to have significant amounts of residual elements due to use of scrap steel in their production. ...
Osmotic consolidation of expansive soil
(Japanese Geotechnical Society Special Publication, 2019)
The mechanical behavior of expansive soils is influenced by the concentration of salts in their pore water. Research
has shown that volume change of soil can occur due to a difference in salt concentration in the pore ...
Assessing the impact of bitumen types on the Performance of asphalt concrete road pavement construction in Uganda
(Kyambogo University (un published work), 2018-12)
This research was conducted to assess the impact of local asphalt binders on the
performance of asphalt concrete road pavement construction in Uganda. The bitumen
samples were collected from ongoing road construction ...
