Inverse Problems in Underwater Acoustics

The paper presents an overview of the inverse problems associated with applications of underwater acoustics. The problems are classified into four main categories, according to the recoverable quantities : Acoustic source localization, bottom identification, ocean acoustic tomography and target recognition. The paper gives emphasis to the three first categories, and includes methods to solve th...

Quantitative Thermo-acoustics and related problems

Thermo-acoustic tomography is a hybrid medical imaging modality that aims to combine the good optical contrast observed in tissues with the good resolution properties of ultrasounds. Thermo-acoustic imaging may be decomposed into two steps. The first step aims at reconstructing an amount of electromagnetic radiation absorbed by tissues from boundary measurements of ultrasounds generated by the ...

Building Practical Spoken Dialog Systems

This tutorial will give a practical description of the free software Carnegie Mellon Olympus 2 Spoken Dialog Architecture. Building real working dialog systems that are robust enough for the general public to use is difficult. Most frequently, the functionality of the conversations is severely limited down to simple question-answer pairs. While offthe-shelf toolkits help the development of such...
