Carbon-incorporated CdO (CdO–C) nanocrystallites were synthesised by sol–gel technique including sucrose (C12H22O11) as a source of carbon ions. This investigation aimed to disclose the necessary synthesis conditions to create room-temperature ferromagnetic (RT-FM) properties in host CdO–C system. Therefore, structural, optical and magnetic properties of CdO–C samples were systematically investigated. The [...]
Uplink Performance Enhancement through Adaptive Multi-Association and Decoupling in UHF-mmWave Hybrid Networks
The rapid increase of wireless applications and services coupled with the arrival of 5G and Internet of Things will not only exacerbate demand for further capacity at the downlink (DL) but also crucially at the uplink (UL). One of the most potential enablers to simultaneously optimize both links is the [...]
Europium incorporation dynamics within NiO films deposited by sol-gel spin coating: Experimental and theoretical studies
Europium doped NiO thin films were grown onto glass substrates via sol-gel spin coating. The evolution of crystal structure, surface topography, and optical properties of NiO was investigated as a function of Eu doping concentration. AFM observations and XRD analysis revealed that NiO:Eu films composed of nano-sized grains exhibit a [...]
Optimization of Precursor Concentration for the Fabrication of V2O5 Nanorods and their MSM Photodetector on Silicon Substrate
This paper presents the effects of precursor concentration on different properties of the V2O5 nanorods (NRs) grown by using spray pyrolysis technique. The V2O5 NRs with different precursor concentrations of VCl3 such as 0.05 M, 0.10 M, 0.15 M, and 0.20 M were prepared on the silicon (Si) substrates. The structural characteristics of NRs [...]
A fault location system using gis and smart meters for the LV distribution system
This paper presents a proposed fault locating system for the low voltage distribution systems in Bahrain using the existing installed smart meters and the geographical information system (GIS). The currently used methods for locating faults in the low voltage distribution system in Bahrain are very time consuming, unreliable and potentially [...]
Reverse osmosis (RO) membrane desalination driven by wind and solar photovoltaic (PV) energy: State of the art and challenges for large-scale implementation
The use of Reverse Osmosis (RO) desalination has grown considerably in response to water scarcity. Despite steady improvements in efficiency, RO desalination remains an energy-intensive process. Numerous studies focussed on using mature Renewable Energy Sources (RES), such as wind and solar photovoltaic (PV) energy, to drive RO plants on a [...]
