In this paper, we investigate the outage performance of dual-hop multiuser multi-relay cognitive radio networks under spectrum sharing constraints.Using an efficient relay-destination selection scheme, the exact and asymptotic closed-form expressions for the outage probability are derived.From these expressions it is indicated that the achieved div
Abstract Microalgae have recently emerged as a key research topic, especially as biological models.Among them, Door Chest the green alga Klebsormidium nitens, thanks to its particular adaptation to environmental stresses, represents an interesting photosynthetic eukaryote for studying the transition stages leading to the colonization of terrestrial
The rotor design of Synchronous Reluctance Motors (SynRMs) has a large effect on their efficiency, torque density and torque ripple.In order to achieve a good compromise between these three goals, an optimized rotor geometry is necessary.A finite element method (FEM) is a good tool for the optimization.However, the computation time is an obstacle a
The inhabitants and local Volleyball - Kneepads governments may treat landscape heritage resources as a cumbersome legacy, which disrupts development, or may see its potential, which may serve as the cornerstone for building a sense of local identity.These issues shall be of special importance in the case of areas located on the outskirts of cities
