The S-Transform From a Wavelet Point of View

Abstract—The -transform is becoming popular for time-frequency analysis and data-adaptive filtering thanks to its simplicity. While this transform works well in the continuous domain, its discrete version may fail to achieve accurate results. This paper compares and contrasts this transform with the better known continuous wavelet transform, and defines a relation between both. This connection allows a better understanding of the -transform, and makes it possible to employ the wavelet reconstruction formula as a new inverse -transform and to propose several methods to solve some of the main limitations of the discrete -transform, such as its restriction to linear frequency sampling.This work was supported by the projects SigSensual ref. CTM2004-04510-C03-02 and NEAREST CE-037110. The work of M. Schimmel was supported through the Ramon y Cajal and the Consolider-Ingenio 2010 Nr. CSD2006-00041 program.Peer reviewe

DISPAR: A tool to model bottom trawl fishing gears

Marine Technology Workshop (Martech05), 17-18 November 2005, Vilanova i la Geltrú, Barcelona.-- 1 pageBottom trawl fishing is a relevant extractive economic activity. However, the limitation of resources and the impact on the environment demand for a more rational exploitation in order to render the activity sustainable and productive in a near future. To this purpose it is important to understand and to analyze the behaviour of fishinggears. DISPAR is a collaboration project betweenthe UPC-CTVG and the CSIC aimed to movetowards this direction.
