Distant-talking automatic speech recognition (ASR) represents an extremely challenging task. The major reason is that unwanted additive interference and reverberation are picked up by the microphones besides the desired signal. A hands-free human-machine interface should therefore comprise a powerful acoustic preprocessing unit in line with a robust ASR back-end. However, since perfect speech e...

A highly selective methacrylic based molecularly imprinted polymer (MIP) was synthesized and applied for the separation and the pre-concentration of salbutamol in urine samples. Spectrophotometric determination of salbutamol was achieved using 2,6-dichloroquinone chlorimide as colorimetric reagent. The detection limit of the method was ca. 13 ng mL in urine after pre-concentration of the sample...

Microchannels can separate analytes faster with higher resolution, higher efficiency and with lower reagent consumption than typical column techniques. Unfortunately, an impediment in the path toward fully integrated microchannel-based labs-on-a-chip is the integration of pre-separation sample processing. Although possible in microchannels, such steps are challenging because of the difficulty i...

Fingerprints are a great basis for identification of persons. Fingerprint recognition is one of oldest procedures of biometric identification. However outcome a good fingerprint image is not always easy. So a fingerprint image must be pre-processed before matching. The objective of this paper is to present animproved and enhanced fingerprint image. We have considered the factors relating to obt...

A study of the Mn K absorption pre-edges in oxides using resonant inelastic X-ray scattering (RIXS) spectroscopy is presented. The energy transfer dimension enhances the separation of the pre-edge (predominantly 1s to 3d transitions) from the main K-edge and a detailed analysis is thus possible. The RIXS spectra are sensitive to the Mn spin state. The technique thus yields detailed information ...

Neuroblastoma x glioma hybrid cells (NG108CC15) were examined for the presence of ?-endorphin-like material. In order to differentiate this ?-endorphin-like material from crude cell extract, a procedure for immunoaffinity chromatography was developed. The monoclonal antibody 3-E7 employed possesses the unique property of recognizing the N-terminal sequence of virtually all endogenous opioid pep...

Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes during the separation period; SP) and group 3 (a recording of the owner's voice was played during SP). The dog's ...
