—We present the Dynamic Programming Projected Phase-Slope Algorithm (DYPSA) for automatic estimation of glottal closure instants (GCIs) in voiced speech. Accurate estimation of GCIs is an important tool that can be applied to a wide range of speech processing tasks including speech analysis, synthesis and coding. DYPSA is automatic and operates using the(More)
We present the DYPSA algorithm for automatic and reliable estimation of glottal closure instants (GCIs) in voiced speech. Reliable GCI estimation is essential for closed-phase speech analysis, from which can be derived features of the vocal tract and, separately, the voice source. It has been shown that such features can be used with significant advantages(More)
Biometrics is the automated method of recognizing a person based on a physiological or behavioural characteristic. Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions. In the last few years there is increasing evidence that technologies based on multimodal biometrics(More)
Biometrics is an automated authentication mechanism that allows the identification or verification of individual based on unique physiological and be-havioural characteristics. The combination of two or more biometric technologies in one application, better known as a multimodal biometric system, can provide enhanced security. Apart from the sound choice of(More)
The objective of this work is to propose the use of innovative low-cost wireless sensor network nodes equipped with smart antennas, so as to meet the goal of creating a sustainable and safe building environment. The proposed wireless sensor network system can provide information on people density within building areas, information that can be used in a(More)
Arrhythmia is one of the most difficult problems in Cardiology and especially in Pediatric Cardiology. In this study, we present a mobile health (m-Health) system that will be used for continuous monitoring of children with suspected cardiac arrhythmias. The system is able to do real-time acquisition and transmission of ECG signals, and facilitate an alarm(More)
