(University of Pretoria, 2020)Spatial diversity is an effective diversity technique used in multiple antenna wireless systems. It requires that antenna elements be sufficiently distributed by at least ten times the signal wavelength (10λ). Sufficient ...
-
(Institute of Electrical and Electronics Engineers, 2019-10)Impedance spectroscopy was performed on Sodium Chloride and Magnesium Sulphate solutions to accurately determine Total Dissolved Solids (TDS) in solution. This was done despite the electrical conductivity measurement (the ...
-
(Hindawi Publishing, 2019-08-29)High-altitude platforms (HAPs) are quasi-stationary aerial wireless communications platforms meant to be located in the stratosphere, to provide wireless communications and broadband services. They have the ability to fly ...
-
(Institute of Electrical and Electronics Engineers Inc, 2020-05)Double-ridge guide horn (DRGH) antennas are widely used in antenna and EMC testing facilities as feed antennas and gain transfer standards. Increasing the low-frequency gain to obtain a more constant 3 and 10 dB beamwidth, ...
-
(University of Pretoria, 2019)To investigate cochlear implant (CI) performance, geometric computational models of the cochlea have been used to assess and optimise electrode insertion strategies and to investigate current flow through the cochlear ...
-
(SpringerOpen, 2019-01-08)In this paper, a new approach to energy harvesting and data transmission optimization in a heterogeneous-based multi-class and multiple resource wireless transmission wireless sensor network system that focus on ...
-
(SpringerOpen, 2019-01-30)Image enhancement is an integral component of face recognition systems and other image processing tasks such as in medical and satellite imaging. Among a number of existing image enhancement methods, metaheuristic-based ...
-
(Elsevier, 2019-02)Energy and water insecurities are global challenges, especially in arid and semi-arid regions. This paper proposes an optimal energy-water nexus management approach in residences using alternative energy and water resources, ...
-
(Elsevier, 2019-02)When sizing distributed hybrid renewable energy systems (HRESs) it has been found that capital costs can significantly be reduced when socio-demographic factors are considered. Unique electricity usage patterns have ...
-
(Elsevier, 2019-02)The increasing interest in renewables has encouraged power system planners to include the concept of hybrid energy systems in modern power industry. Besides, the modern power consumers are becoming more concerned about ...
-
A model-based deep learning approach to spectrum management in distributed cognitive radio networks (University of Pretoria, 2020)The acceleration towards the fifth generation (5G) and beyond will see the internet of things (IoT) being the primary strategy of deployment, and wireless networks will become more distributed and autonomous. Furthermore, ...
-
(University of Pretoria, 2020)Virtual reality (VR) applications are becoming increasingly popular and are being used in various applications. VR applications can be used to simulate large real-world landscapes in a computer program for various purposes ...
-
(Elsevier, 2019-02)This paper presents the computational study of convective heat transfer enhancement and entropy generation performance by using bluff cylinder. A two-dimensional numerical simulation is executed successfully on thermo-hydraulic ...
-
(Elsevier, 2019-02)Owing to the increase in electrical load demand the dimension of interconnected energy system is increasing day by day and getting more complex with power injection from renewable technologies such as wind energy in order ...
-
(Elsevier, 2019-02)This work presents the effect of electron irradiation on the full symmetric cell using the pure polymer base AC material and irradiation on the full cell was analyzed for different exposure times. An improvement of the ...
-
(Elsevier, 2019-02)Combined heat and power is utilized to generate electric power and produce thermal energy for various applications. In view of this, we investigate the economic savings and environmental effects of using a co-generation ...
-
(Elsevier, 2019-02)Advanced building structures are extremely complicated with a large number of dynamically interacting components and widely equipped with multi-zone air conditioning (ME A/C) systems. In this paper, multi-zone commercial ...
-
(Elsevier, 2019-02)In this paper an attempt is made to propose the different models of control and design such as integral derivative (ID), proportional integral derivative (PID) and integral double derivative (IDD) effectively optimized ...
-
(MDPI Publishing, 2019-07-22)This paper proposes a multi-agent-based collaborative virtual manufacturing environment (VME) to save energy consumption and improve efficiency in the manufacturing process. In order to achieve the high autonomy of the ...
-
(MDPI Publishing, 2019-06-06)Compressed natural gas stations serve customers who have chosen compressed natural gas powered vehicles as an alternative to diesel and petrol based ones, for cost or environmental reasons. The interaction between the ...
