Due to exponential growth in the daily usage of vehicles, the traffic congestion and roadside accidents are increasing day by day.The communication among vehicles is critical to avoid the emergencies and to address the issue of congestion of vehicles.Internet of vehicles provides the communication channel between the vehicles, but existing solution
A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper.Assuming that the perfect channel state information is available, we aim to maximize the secrecy rate while satisfying chervo jacke herren the quality of service of the legitimate users
Corrosion is the most frequent but also the most deleterious deterioration mechanism affecting reinforced concrete.In addition to the economic impact color touch 7/97 of the repair works, for historical concrete structures, corrosion can generate irreversible losses of original material of great cultural value.If the usual non-destructive electroch
