In this paper the procedure for feature vector extraction and the problems, which must be solved, by defining the feature vectors, which contain only the information about the speech signal are described. A new procedure of feature extraction which is based on the frame elimination and frequency spectrum reduction for the noisy part of the speech signal is proposed. For all tests the Slovenian ...

In this work, a splitting and weighting scheme that allows for splitting a Gaussian density into a Gaussian mixture density (GMM) is extended to allow the mixture components to be arranged along arbitrary directions. The parameters of the Gaussian mixture are chosen such that the GMM and the original Gaussian still exhibit equal central moments up to an order of four. The resulting mixtures’ co...

We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intelligent and informed eavesdropper who is as capable as the intended receiver, but has different channel parameters. We aim to provide perfect secrecy for the transmitters in this multi-access environment. Using Gaussian co...

Measurements of pulmonary excretion of methane (CH(4)) were used to obtain information on the CH(4)-producing bacteria in man. Preliminary studies indicated that (a) all CH(4) excreted by man is produced by colonic bacteria, (b) there is no appreciable utilization of CH(4) by man, and (c) breath CH(4) can serve as a relatively accurate indicator of CH(4) production in the intestine. The rate of...

2',2'-Difluorodeoxycytidine (dFdC, Gemcitabine) is a deoxycytidine analogue which, after phosphorylation to the 5'-di- and 5'-triphosphate (dFdCTP), induces inhibition of DNA synthesis and cell death. We examined the values for elimination kinetics of cellular dFdCTP and found they were dependent on cellular concentration after incubation of CCRF-CEM cells with dFdC and washing into drug-free m...

BACKGROUND In 2005, the Government of Senegal embarked on a campaign to eliminate a Glossina palpalis gambiensis population from the Niayes area (∼ 1000 km(2)) under the umbrella of the Pan African Tsetse and Trypanosomosis Eradication Campaign (PATTEC). The project was considered an ecologically sound approach to intensify cattle production. The elimination strategy includes a suppression phas...

This paper reports ab intio, DFT and transition state theory (TST) calculations on HF, HCl and ClF elimination reactions from CH2Cl–CH2F molecule. Both the ground state and the transition state for HX elimination reactions have been optimized at HF, MP2 and DFT calculations with 6-31G*, 6-31G** and 6311++G** basis sets. In addition, CCSD(T) single point calculations were carried out with MP2/6-...

Normal albumin loss from the plasma is thought to be minimized by a number of mechanisms including charge repulsion with the capillary wall and an intracellular rescue pathway involving the major histocompatibility compex (MHC)-related Fc receptor (FcRn)-mediated mechanism. This study investigates how these factors may influence the mechanism of hypoalbuminemia. Hypoalbuminemia in rats was indu...

Reliable information about the elimination rate of alcohol (ethanol) from blood is often needed in forensic science and legal medicine when alcohol-related crimes, such as drunken driving or drug-related sexual assault are investigated. A blood sample for forensic analysis might not be taken until several hours after an offence was committed. The courts usually want to know the suspect's blood-...
