Automatic analysis of the structure of a music piece aims to recover its sectional form: segmentation to musical parts, such as chorus or verse, and detecting repeated occurrences. A music signal is here described with features that are assumed to deliver information about its structure: mel-frequency cepstral coefficients, chroma, and rhythmogram. The features can be focused on different time ...

This paper describes the automatic design of methods for detecting fraudulent behavior. Much of the design is accomplished using a series of machine learning methods. In particular, we combine data mining and constructive induction with more standard machine learning techniques to design methods for detecting fraudulent usage of cellular telephones based on pro-ling customer behavior. Speciical...

We present some asymptotic results about the frequency of a letter appearing in a generalized unidimensional automatic sequence. Next, we study multidimensional generalized automatic sequences and the corresponding frequencies.

Technical reports from the Automatic Control group in Linkping are available by anonymous ftp at the address ftp.control.isy.liu.se. This report is contained in the compressed postscript le 2014.ps.Z. Abstract The problem of designing the identiication experiments to make them maximally informative with respect to the intended use of the model is studied. A focus will be on model based control ...

The intelligent reflecting surface (IRS) is an emerging technique to extend wireless coverage. In this letter, the performance of hybrid automatic repeat request (hybrid ARQ) for IRS-assisted system analysed. More specifically, outage IRS-aided using ARQ protocol with chase combining studied. asymptotic analysis also shows that better and improves linearly by increasing number reflectors system...

© 2009 Goran T. Djordjevic et al. 619 ABSTRACT⎯In this letter, we study the influence of receiver imperfections on bit error rate (BER) degradations in detecting low-density parity-check coded multilevel phase-shift keying signals transmitted over a Rician fading channel. Based on the analytical system model which we previously developed using Monte Carlo simulations, we determine the BER degra...

In this letter, we present useful features accounting for pronunciation prominence and propose a classification technique for prominence detection. A set of phone-specific features are extracted based on a forced alignment of the test pronunciation provided by a speech recognition system. These features are then applied to the traditional classifiers such as the support vector machine (SVM), ar...

For the foreign student it is very important to own skills of the academic letter. It is an important indicator of professional and research competence of the student. The mobility of foreign graduates of the Russian higher education institutions depends on their level of proficiency in the academic Russian letter as communications between the educational and scientific organizations extend at ...
