1 + 3 covariant perturbations in power-law f(R) gravity
(The European Physical Journal C, 2021)We applied the 1+3 covariant approach around the Friedmann–Lemaître–Robertson–Walker (FLRW) background, together with the equivalence between f (R) gravity and scalar-tensor theory to study cosmological perturbations. We ... -
Abell 1430: A merging cluster with exceptional diffuse radio emission
(Astronomy and Astrophysics, 2021)Context. Di_use radio emission has been found in many galaxy clusters, predominantly in massive systems which are in the state of merging. The radio emission can usually be classified as relic or halo emission, which are ... -
AI Based Wireless Traffic Light Detector using Image Classification in Machine Learning to Reduce Road Traffic Accidents: A Case Study of Uganda’s Road Traffic
(International Journal of Electronics Communication and Computer Engineering, 2021)Road traffic accidents in Uganda have led to many deaths. This unfortunately occurs to pedestrians, users of private and public means of transportations. Many solutions have however focused on for example: sensitization, ... -
Analysis of ionospheric storm‑time effects over the East African sector during the 17 March 2013 and 2015 geomagnetic storms
(Earth, Planets and Space, 2023)An analysis of the mechanisms that caused the storm-time effects during two geomagnetic storms that occurred on 17 March 2013 and 2015 is presented. We used Global Navigation Satellite System (GNSS) derived Total Electron ... -
Are the observed gaps in protoplanetary discs caused by growing planets?
(Royal Astronomical Society, 2019-04-13)ABSTRACT Recent detailed observations of protoplanetary discs revealed a lot of substructures that are mostly ring like. One interpretation is that these rings are caused by growing planets. These potential planets are ... -

Characterisation of Total Electron Content over African region using Radio Occultation observations of COSMIC satellites
(Elsevier Ltd, 2019-08-08)Abstract This study characterised the Total Electron Content (TEC) over the African region during the years 2008–2015. The TEC data used were the integrated electron density observed during Radio Occultation (RO) event ... -
Characterization of the Low Latitude Plasma Density Irregularities Observed using C/NOFS and SCINDA Data.
(Advances in Space Research, 2017-08-04)Abstract Complex electrodynamic processes over the low latitude region often result in post sunset plasma density irregularities which degrade satellite communication and navigation. In order to forecast the density ... -
Classification of Fuzzy Logic Linguistic Terms for Accurate Load Balancing in Electric Power Distribution System.
(International Conference on Electrical, Computer and Energy Technologies (ICECET), 2021)Intelligent controls in electric power distribution system can be used to improve electric power distribution by balancing loads in a three-phase system at any time. One of such intelligent controls is fuzzy logic. In this ... -
Climatology of ionospheric scintillations and TEC trend over the Ugandan region
(Advances in Space Research, 2013-12)This study presents results on the investigation of the diurnal, monthly and seasonal variability of Total Electron Content (TEC), phase (rU) and amplitude (S4) scintillation indices over Ugandan (Low latitude) region. ... -
Cosmological perturbations in f(G) gravity
(International Journal of Modern Physics D, 2021)We explore cosmological perturbations in a modified Gauss-Bonnet f(G) gravity, using a 1+3 covariant formalism. In such a formalism, we define gradient variables to get perturbed linear evolution equations. We transform ... -
