Common architecture for discrete wavelet transform analysis and synthesis with sequential and constant processing elements
(2004-10-08)
This paper adresses the problem on processing biological data such as cardiac beats, audio and ultrasonic range, calculating wavelet coefficients in real time, with processor clock running at frequency of present ASIC's ...
Mathematical tests about the existence and applications of PPS-wavelets in function approximation problems
(Spie - Int Soc Optical Engineering, 1998-01-01)
Neural networks and wavelet transform have been recently seen as attractive tools for developing eficient solutions for many real world problems in function approximation. Function approximation is a very important task ...
Harmonics filtering and detection of disturbances using wavelets
(1999-12-01)
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...
Microcalcification enhancement and classification on mammograms using the wavelet transform
(2008-11-24)
This paper presents a method to enhance microcalcifications and classify their borders by applying the wavelet transform. Decomposing an image and removing its low frequency sub-band the microcalcifications are enhanced. ...
Rotor Failure Diagnosis of Induction Motors by Wavelet Transform and Fourier Transform in Function of the Load
(Destech Publications, Inc, 2015-01-01)
This paper presents two diagnostic methods for the online detection of broken bars in induction motors with squirrel-cage type rotors. The wavelet representation of a function is a new technique. Wavelet transform of a ...
Comparative study between RBF and radial-PPS neural networks
(Spie - Int Soc Optical Engineering, 1998-01-01)
The study of function approximation is motivated by the human limitation and inability to register and manipulate with exact precision the behavior variations of the physical nature of a phenomenon. These variations are ...
Multipath reduction from GPS double differences using wavelets: How far can we go?
(2004-12-01)
Wavelets are being extensively used in Geodetic applications. In this paper, the Multi-Resolution Analysis (MRA) using wavelets is applied to pseudorange and carrier phase GPS double differences (DDs) in order to reduce ...
