Abstract As one of the most critical technologies in signal detection, weak detection has received a great deal attention many areas. Traditional methods perform well when number is single and form simple, which are quite different from situation some real applications (e.g., marine communication scenario). In this paper, we consider problem high-precision frequency multiple variable-frequency ...

In this submission for MIREX 2015 we utilize an efficient latent variable model for multiple-F0 estimation and note tracking, which uses an ERB-scale time-frequency representation as input. The transcription model is based on probabilistic latent component analysis and uses preextracted spectral templates corresponding to sound states for several instruments. Three system variants are submitted...

the present study is aimed at investigating the factors which influence cooperative managers’ awareness of the cooperative sector. methodologically, this is a descriptive-correlated survey. the study consisted of 498 managers of agricultural cooperatives in tehran(n=498), from among whom 72 were selected through random sampling (n=72). validity of the questionnaire used for collecting data was ...
