a windowing function that is based on the well-known Butterworth filters was proposed [1] with the claim that it can solve " the tradeoff problem between the frequency resolution and spectral leakage in the estimated power spectral density, unavoidable with the conventional windows. " That claim is a consequence of not considering the available time duration in the window design for which we pr...

We present an efficient algorithm for image restoration from highly noised originals. The algorithm is based on diverse library of tight and semi-tight wavelet frames. Unlike majority of current denoising methods, which threshold the transform coefficients, our algorithm performs direct and inverse multiscale transforms using properly modified frame filters. No thresholding is applied. The proc...

Retinopathy of prematurity (ROP) is an eye disease in premature infants. It mostly happens in babies weighing less than 0011 g and gestational age less than 10 weeks. The growth of retinal vessels are interrupted in premature infants and the retina has been unable to get enough oxygen and food. So, the delay in diagnosis may lead to blindness. Therefore it is necessary to follow the premature i...

Note: This paper grew out of an invitation to Pat Keating to summarize and critique the model of phonological encoding presented in Levelt, Roelofs and Meyer (1999) at the Labphon7 meeting in Nijmegen, the Netherlands, in 2000. As a result, and because this model specifically addresses the problems of phonological and phonetic processing which concern us here, we focus largely on it, leaving li...

In this paper we address some of the concerns raised by Butterworth and Punt (1994) in SC/46/AS2 regarding the Bayesian synthesis method. We argue that the sensitivity of the Bayesian synthesis approach is similar to that of alternative methods, and that the ease with which sensitivity can be detected is one of the advantages of the method. We also note that some of the examples in SC/46/AS2 us...

In the present study, a comprehensive and systematic strategy was described to evaluate the performance of several three-way calibration methods on a bio-analytical problem. Parallel factor analysis (PARAFAC), alternating trilinear decomposition (ATLD), self-weighted alternating trilinear decomposition (SWATLD), alternating penalty trilinear decomposition (APTLD) and unfolded partial least squa...
