In this paper a novel approach for detection of peaks in spectral representations of music signals is proposed. The basic idea is to detect local maxima in any digitized signal and employ statistical techniques for filtering out spurious peaks which are the result of imperfections and noise in spectral representations of music signal.

UNLABELLED Many DNA functional motifs tend to accumulate or cluster at specific gene locations. These locations can be detected, in a group of gene sequences, as high frequency 'peaks' with respect to a reference position, such as the transcription start site (TSS). We have developed a web tool for the identification of regions containing significant motif peaks. We show, by using different yea...

Finding and identifying characteristic or meaningful image sequences in a continuous video stream is a challenging task with many applications. This paper presents a new and efficient approach to these temporal segmentation and classification problems based on Hidden Markov Models (HMMs). The basic principle consists in continuously observing the output scores of the HMMs at every time step. Pe...

Samples were collected monthly at four fixed stations in Mida creek from May 1996 to April 1997, in order to determine the species composition, abundance and diversity of phytoplankton and zooplankton collected with 20and 332-μm mesh size plankton nets respectively. Sampling also included measurement of salinity and temperature. Peaks in phytoplankton abundance occurred in May and January, foll...

A description of the light curves of microlensed Type Ia supernovae (SNe Ia) as extended and expanding sources is presented. We give examples of what microlensing by stellar-mass Chang-Refsdal lenses can do to a small percentage of supernova light curves. We find that in addition to overall brightening, significant changes in light–curve shapes can also occur. Peaks can be distorted, plateaus c...

Let us call a lattice path in Z × Z from (0, 0) to (n, 0) using U = (1, k), D = (1,−1), and H = (a, 0) steps and never going below the x-axis a (k, a)-path (of order n). A super (k, a)-path is a (k, a)-path which is permitted to go below the x-axis. We relate the total number of humps in all of the (k, a)paths of order n to the number of super (k, a)-paths, where a hump is defined to be a seque...
