Traditional power grids are currently being transformed into smart (SGs). SGs feature multi-way communication among energy generation, transmission, distribution, and usage facilities. The reliable, efficient, intelligent management of complex systems requires integration high-speed, secure data information technology the to monitor regulate generation usage. Despite several challenges, such as trade-offs between wireless coverage capacity well limited spectral resources in SGs, is a...
Internet of Things (IoT) is a world wide network interconnected objects. IoT capable objects will be through wired and wireless communication technologies. However, cost-effectiveness issues accessibility to remote users make as feasible solution. A majority possibilities have been proposed but many these suffer from vulnerabilities dynamic environmental conditions, ease access, bandwidth allocation utilization, cost purchase spectrum. Thus trends are shifting the adaptability Cognitive...
Cognitive radio technology can facilitate communication in smart grid applications through dynamic spectrum access. However, traditional routing and MAC protocols adopted for cognitive networks may not be beneficial CR-based environments due to large data sizes variable link quality among different functional blocks of grids. The interference fading wireless links necessitate efficient reliable low-latency delivery applications. This must achieved while protecting the legitimate primary...
The Al-Salam Lagoon is one of the recreational sites along Jeddah coast, showing environmental impacts urbanization coast. A sediment core (220 cm) was collected from intertidal zone to evaluate heavy metals (Fe, Mn, Cr, Ni, Cu, Zn, and Pb) geochemical indices (contamination factor, geo-accumulation index, pollution load index). In organ-ic-rich muddy sediments (0–100 cm), there a high content index ~3, indicting anthropogenic with Cu contamination (CF:12) moderate Fe, Pb (CF: <3)....
Abstract We have analysed two Late Holocene records, each about 5 ka long, consisting of varved sediments deposited in the oxygen minimum zone off Pakistan (upper continental slope Ormara and west Karachi). Varve counting was checked by accelerator mass spectrometry (AMS) 14 C dating. Detailed lithofacies analysis, ultra-high-resolution X-ray fluorescence scanning, flux rates from sediment traps lamina-by-lamina-analysis a year record (1993–1998) support our interpretation annual character...
Abstract Petrographic and geochemical data for new basalt peridotite samples recovered from sampling sites at the Southern Murray Ridge help to constrain models evolution of Owen-Murray system, which forms northwestern boundary Indian plate. Trace elements immobile during alteration (Ti, Zr, Nb, Y rare earth elements) suggest that altered microphyric metabasalt has affinities magmatism active margins (island-arc tholeiite sensu lato ). It is distinctly different mid-ocean ridge basalt,...
This study utilizes lithofacies characteristics, petrographic, XRD, and stable isotope data of Al-Mejarma beachrocks, Red Sea, Saudi Arabia, to interpret its depositional setting, origin cement, coastal evolution. The beachrock is 1.15 m thick, medium very coarse-grained sandstone with scattered granules. It shows massive graded bedding, horizontal, ripple, shore parallel slightly oblique planar cross-laminations, a remarkable absence bioturbation. was deposited by shore-parallel longshore...
Recent developments in wireless networks, MicroElectroMechanical systems technology and integrated circuits have enabled miniaturisation of micro/nano-sensor nodes. These low-power intelligent nodes are placed or around the human body a strategic manner for numerous new, practical innovative applications. applications provide improved data speed, accuracy reliable communication sensors actuators. This exciting new area research based on miniaturised sensor is called networks (BANs). With...
Introduction: Silicone breast implants are widely used for aesthetic and reconstructive purposes, but their rupture remains a serious complication, especially when triggered by infection. Infection around the implant can lead to various complications, including capsule formation, rupture, skin ulceration. This study explores relationship between infection silicone leading ulceration, with focus on clinical features, management strategies, patient outcomes. Objective: To investigate...
