Arch Display Shelf The nonstationary elasto-electrodynamics problem for an anisotropic piezoceramic cylinder of finite size with circumpolarization of material is considered for the case when the tangential stresses and the electric potential influence on the radial outside of the cylinder as the arbitrary functions of axial coordinate and time.The
Runway surface friction is critically important to safe aircraft operations and mostly depends on the surface texture, which provides grip in the presence of contamination and directly affects the friction coefficient in general.Microtexture assessment is the most challenging part of texture assessment since there is no standardised pavement microt
A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has Face Tint been studied in this paper.Assuming that the perfect channel state information is available, we aim to maximize the secrecy rate while satisfying the quality of service of the legitimate users and power
Climate factors can impact the multifunctionality of steppe ecosystem by altering plant diversity.The pivotal role of diversity in mediating these effects is of paramount importance.Given that various facets of plant diversity exhibit diverse responses to climate change and impart distinct impacts on steppe ecosystem multifunctionality, the elucida
Simultaneous localization and mapping (SLAM) is one of the key technologies for mobile robots to achieve autonomous driving, and the lidar SLAM algorithm Horse Chest Buckles is the mainstream research scheme.Firstly, this paper introduces the overall framework of lidar SLAM, elaborates on the functions of front-end scan matching, loop closure detec
