Bottlenose dolphin Tursiops truncatus (Montagu, 1821) is a cosmopolitan species; it is found in all tropical and temperate coastal waters of the world. The bottlenose dolphins in the Mediterranean Sea mainly show coastal habits, which often lead it to interact with fishing activities. In this study, first data on the diet of specimens of T. truncatus stranded in Tuscany, north-western Mediterra…

This study was carried out in the Regional Park of San Rossore (Italy) where we found natural regeneration of Stone pine (Pinus piena L.) in an even-aged stand of pine. The objectives of our study were to characterize the forest structure of the Stone pine stand and to quantify the natural regeneration of pine. Our results show that natural regeneration of P. pinea in the Park of San Rossore is…
Italy was one of the countries severely affected by the Covid-19 pandemic. An analysis of the factors that played a role in the spread of this epidemic is necessary. However, the assessment of which factors may be specific, and which may contribute the most is complex and involves a high degree of uncertainty. The main objective of this study is to evaluate and analyse the statistical associati…
Filter bank multi‐carrier (FBMC) modulation, as a potential candidate for physical data communication in the fifth generation (5G) wireless networks, has been widely investigated. This chapter focuses on the spectral efficiency analysis of FBMC‐based cognitive radio (CR) systems, and spectral efficiency comparison is conducted with another three types of multi‐carrier modulations: orthogo…

The heterogeneous cellular network (HCN) is most significant as a key technology for future fifth-generation (5G) wireless networks. The heterogeneous network consists of randomly macrocell base stations (MBSs) overlaid with femtocell base stations (FBSs). Stochastic geometry has been shown to be a very powerful tool to model, analyze, and design networks with random topologies such as wireless…
