The paper presents an overview of the 15 year long development of fetal phonocardiography including the works on the applied signal processing methods for identification of sound components. Based on the improvements achieved on this field, the paper shows that beyond the traditional CTG test the phonocardiography may be successfully applied for long-term(More)
The main purpose of this paper is to demonstrate the capability of fetal phonocardiographic measurements to indicate some congenital heart defects. It deals with the results of investigations carried out during the last four years involving 820 pregnant women. During the investigations fetal cardiac murmurs presenting typical waveforms and incidences of(More)
The two important problems of collaborative intrusion detection are aggregation and correlation of intrusion events. The enormous amount of data generated by detection probes requires significant network and computational capacity to be processed. In this article we show that a distributed hash table based approach can reduce both network and computational(More)
This paper presents a complex heuristic method for the evaluation of fetal heart sounds, applying simultaneously several algorithms, where the autocorrelation technique has been completed with the wavelet transform and the matching pursuit methods. In this way, a more reliable heart rate variability can be achieved and further parameters of the cardiac(More)
IntroductIon The importance of the host security problems come into prominence by the growth of the Internet, since the network means a breaking point to the intruders (Wang, Jha, McDaniel, & Livny, 2004). The article presents the e-collaboration related security questions, the main concepts of the intrusion BLOCKINdetection and the different classes of the(More)
IntroductIon The importance of real-time pattern recognition in streaming media is rapidly growing (Liu, Wang, & Chen, 1998). Extracting information from audio and video streams in an e-collaboration scenario is getting increasing relevance as the networking infrastructure develops. This development enables the use of rich media content. Shared archives of(More)
