VNE-HPSO: VIRTUAL NETWORK EMBEDDING ALGORITHM BASED ON HYBRID PARTICLE SWARM OPTIMIZATION



Combining damage and fracture mechanics to model calving

Calving of icebergs is a major negative component of polar ice-sheet mass balance.Here we present a new calving model relying on both continuum damage mechanics and linear Coffee Lid elastic fracture mechanics.This combination accounts for both the slow sub-critical surface crevassing and the rapid propagation of crevasses when calving occurs.First

Channel Training & Estimation for Reconfigurable Intelligent Surfaces: Exposition of Principles, Approaches, and Open Problems

Reconfigurable intelligent surfaces (RIS) are passive controllable arrays of small reflectors that direct electromagnetic energy towards or away from the target nodes, thereby allowing better management of signals and interference in a wireless network.The RIS has the potential for significantly improving the performance of wireless networks.Unfort
