Comparison of Fuzzy Logic and Genetic Algorithm Based Admission Control Strategies for UMTS System

CDMA systems have so-called soft capacity, so the total number of possible sessions has not an exact value. The capacity of CDMA system depends on the interference level in the system. There are therefore RRM (Radio Resources Management) functions, which are responsible for supplying optimum coverage, ensuring efficient use of physical resources and providing the maximum planned capacity. This paper presents and compares several algorithms that are used for admission control purposes in UMTS system. Several versions of fuzzy logic based algorithms, load factor based algorithm and genetic based algorithm are mutually compared via simulations

Effect of deposition angle on fabrication of plasmonic gold nanocones and nanodiscs

Sem informaçãoMetal nanocones can exhibit several strong plasmonic resonances, which are associated with intense and accessible electromagnetic hot spots. They can thus be used to enhance light-matter interactions or to facilitate location-specific sensing while enabli22816Sem informaçãoSem informaçãoSem informaçãoThis research was carried out under project GA17-33767L of Grant Agency of the Czech Republic, H2020 Twinning programme (project SINNCE, 810626) and Brno University of Technology (project FSI-S-17-4482).
