A Comprehensive Review of Low-Cost Big Data Clusters Using Single Board Computers Architectures, Performance, and Applications
The explosive increase in data generation has resulted in an unprecedented need for the availability of scalable and cost-effective big data processing solutions. Although traditional high-performance computing clusters have rich functionality, the energy and cost requirements are high, which inhibits the ability of education facilities, small research groups, and organizations with limited resources to adopt …
Joint Beamforming and Phase Shift Optimization in IRS-Aided NOMA Communications in 6G Networks
The paper explores the joint optimization of beamforming and phase shifts in Intelligent Reflecting Surface (IRS)-aided Non-Orthogonal Multiple Access (NOMA) systems within the context of 6G networks. We propose a novel algorithm that optimizes the beamforming vectors at the base station (BS) and the phase shifts at the IRS to maximize the sum rate of …
Effect of Ankenda (Acronychia pedunculata) Extract as a Fermentation Inhibitor in Tapped Inflorescence Sap of Kithul (Caryota urens) in Sri Lanka
The production of jaggery and treacle from fermented Caryota inflorescence sap presents significant challenges. This study aimed to evaluate the effectiveness of extracts from the leaves, bark, and flowers of Acronychia pedunculata in inhibiting the fermentation of Caryota urens inflorescence sap and to determine the most effective part and concentration for this purpose. Essential oils …
Green Synthesis of Zinc Oxide Nanoparticles for Biocompatible and Sustainable Sunscreens with Enhanced UV Protection and Antibacterial Activity
Sunscreens play a critical role in protecting the skin from harmful ultraviolet (UV) radiation, including both UVA and UVB rays. Traditional inorganic UV filters, such as chemically synthesized zinc oxide (ZnO) and titanium dioxide (TiO₂), have limitations regarding biocompatibility, cost, and sustainability. This study investigates the effectiveness of green-synthesized ZnO nanoparticles (NPs) as an alternative, …
A Study on Soil Erosion Control with Geosynthetic Cementitious Composite Mats for Sustainable Agricultural Practices
Soil erosion is a significant environmental challenge that threatens the sustainability of agricultural practices worldwide. This study investigates the efficacy of geosynthetic cementitious composite mats (GCCMs) in controlling soil erosion and promoting sustainable agriculture. Soil erosion causes the loss of fertile topsoil, reduced productivity, and degradation. Traditional methods have limitations, while GCCMs offer structural and …
