Autor: Bergadà Caramés, Pau

Publikováno v: TDX (Tesis Doctorals en Xarxa).

El sistema de comunicació ràdio d’alta freqüència (HF, en anglès) és usat arreu del món per agències governamentals i no governamentals sempre que calgui una alternativa a les comunicacions via satèl•lit: vaixells a alta mar, avions fora

The improvement of quality of life in the framework of the smart city paradigm cannot be limited to a set of objective measures carried out over several critical parameters (e.g., noise or air pollution). Noise disturbances depend not only on the equ

Ports and harbours are logistic nodes characterized by several types of noise, which can usually occur in a concurrent manner in the same harbour premises: ferries, cruises, fishing and trade ships coexist with other industrial and auxiliary services
