This article introduces several contributions to enhance an important application such as acoustic tomography (AT), using mainly the spatial and spectral diversities of underwater acoustic signals. Due to their inherited properties, (i.e. spareness, non-stationarity or cyclostationarity, wide-band frequency range, wide range of power, etc.), the process of underwater acoustic signals becomes a ...

For several years now, most of the growth of computing power has been made possible by exploiting parallel CPUs on the same chip; unfortunately, state-of-the-art software tools for the simulation of declarative, objectoriented models still generate single-threaded simulation code, showing an increasingly disappointing performance. This paper presents a simple strategy for the efficient computat...

The establishment of a high quality ART program requires a multi-disciplinary effort, involvement and commitment of all staff members - team work. It is of vital importance that all aspects of the treatments are taken into consideration and that you already from the start use international guidelines, standards and indicators to initiate the construction of a well-organised ART program that mee...
