Effective supervision for enhancing quality of doctoral research in computer science and engineering (Springer, 2023-09-05)This article reflects on effective supervision and possible guidance for enhancing quality of doctoral research in the computer science and engineering field. The aims of this study are (1) to understand supervision and ...
-
(University of Pretoria, 2023-06)This work presents the effect of temperature change on the capacitance of GaAs PIN diodes and the resulting change in performance of RF limiters at VHF. Device temperatures were varied between -25 ºC and 100 ºC, with ...
-
(University of Pretoria, 2024-02-12)This study explores the feasibility of constructing a small-scale speech recognition system capable of competing with larger, modern automated speech recognition (ASR) systems in both performance and word error rate (WER). ...
-
(University of Pretoria, 2023)This research introduces an specific emitter identification (SEI) system to enhance secure transmission systems, addressing a critical gap in existing studies. Existing studies lack a comprehensive solution for authenticating ...
-
(University of Pretoria, 2023-08-22)A Wireless Multimedia Sensor Network (WMSN) make possible new surveillance applications in environments that traditional systems would not handle, including search and rescue operations after a disaster. However, WMSNs ...
-
(Nature Research, 2024-01)This work examines the application of machine learning (ML) algorithms to evaluate dissolved gas analysis (DGA) data to quickly identify incipient faults in oil-immersed transformers (OITs). Transformers are pivotal equipment ...
-
(Elsevier, 2024-01)This paper reports a comparative study among four bio-inspired meta-heuristic techniques i.e. Sooty-Tern Optimization (STO), Grey Wolf Optimization (GWO), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) to ...
-
(Elsevier, 2022-11)Renewable energy technologies (RETs) have been universally accepted as the prospective choice to increase the reliability of the power system and reduce the effects of emission cost (EC), fuel cost (FC), maintenance cost ...
-
(Institute of Electrical and Electronics Engineers, 2023-03)Resource allocation (RA) has a significant impact on vehicular network performance. With high mobility, RA is more challenging, as the number of vehicles in close proximity changes dynamically in the nonstationary environment. ...
-
(University of Pretoria, 2023)Exposure to pathogenic Escherichia coli (E. coli) bacteria through contaminated water can cause potentially life-threatening diarrhea and vomiting, and it is a useful water quality indicator. Simulations and experiments ...
-
(Institute of Electrical and Electronics Engineers, 2024-03)The integration of large-scale distributed generators into active distribution networks (ADNs) will aggravate voltage fluctuations, which can affect the secure operation of power grids seriously. In this article, we ...
-
(Institute of Electrical and Electronics Engineers, 2024-03)In this article, we study the optimal feedback control problems of knowledge dissemination processes in multilayer complex networks. First, a node-based model is established in multilayer complex networks and two collaborative ...
-
(Institute of Electrical and Electronics Engineers, 2024-08)This article proposes an optimal controller for a team of underactuated quadrotors with multiple active leaders in containment control tasks. The quadrotor dynamics are underactuated, nonlinear, uncertain, and subject to ...
-
(Institute of Electrical and Electronics Engineers, 2024-06)Due to cyber-physical fusion and nonsmooth characteristics of energy management, this article proposes a security event-trigger-based distributed approach to address these issues with developed smoothing technique. To ...
