Due to its improved spectral efficiency, non-orthogonal multiple access (NOMA) is regarded as a promising multiple access technology for beyond fifth-generation (5G) networks.In this paper, we examine the performance of a cell-edge user and suggest a beamforming scheme in a cooperative two-user multiple-input multiple-output (MIMO)-NOMA system with
The quality of potato seeds is important to support increased production.The majority of farmers do not certify potato seeds, which can result in various risks for potato seed production activities.This research aims to identify the risks of potato seed production and formulate risk control strategies for potato seeds production.The research uses h
In recent years, the use of drones for Allergy Relief recreational and commercial activities has grown rapidly due to their affordability and performance.This growing use raises concerns about the threats drones pose to the security of sensitive areas such as airports, prisons, industrial and military facilities.In response to these threats, drones
Understanding the patterns of chemical exposure among biota across spindle a landscape is challenging due to the spatial heterogeneity and complexity of the sources, pathways, and fate of the different chemicals.While spatially-driven relationships between contaminant sources and biota body burdens of a single chemical are commonly modelled, there
