OBJECTIVE Reducing health and economic burdens from diagnostic delay of psychogenic nonepileptic seizures (PNES) requires prompt referral for video electroencephalography (VEEG) monitoring, the diagnostic gold standard. Practitioners make VEEG referrals when semiology suggests PNES, although few semiological signs are supported by well-designed studies, and(More)
Optical Burst Switching (OBS) is an optical switching technology capable of supporting large demands for bandwidth in optical backbones with Wavelength Division Multiplexing (WDM). This paper presents an OBS simulation model for the discrete event simulator OMNeT++. The performance of this model is compared with the performance of the well-known INET(More)
Detection of emotion in humans from speech signals is a recent research field. One of the scenarios where this field has been applied is in situations where the human integrity and security are at risk. In this paper we are propossing a set of features based on the Teager energy operator, and several entropy measures obtained from the decomposition signals(More)
Automatic emotion recognition considering speech signals has attracted the attention of the research community in the last years. One of the main challenges is to find suitable features to represent the affective state of the speaker. In this paper, a new set of features derived from the wavelet packet transform is proposed to classify different negative(More)
Automatic recognition of emotions in speech has attracted the attention of the research community in recent years. Some of the most relevant proposed applications of it are in call-centers. In these scenarios the speech is distorted by compression algorithms. The effects of such distortion on the performance of systems for automatic recognition of emotions(More)
AIM To assess how efficiently the COMFORT behaviour scale measures acute pain in neonates, in comparison with skin conductance activity, a validated measure of pain and stress. METHODS Images of 36 newborns were analysed before, during and after painful heel pricks to measure glucose levels and compared with skin conductance activity variables. RESULTS(More)
Sepsis, a critical bacterial infection of the bloodstream, is a serious cause of illness in neonatal period in both premature and at term newborns. It is important to look for parameters that can help earlier detection of sepsis in the newborn. Previous studies have shown that Heart Rate Variability is reduced when associated with sepsis and diminish the(More)
The estimation of the fundamental frequency (F0) in speech is a very important task that has been addressed by many researchers. F0 estimation can be used to separate two kind of frames from an utterance, those where the vocal folds vibrate (voiced sounds) and those where not (unvoiced sounds). The methods used to estimate F0 are affected by the presence of(More)
Monitoring animal species by means of the automatic sound recognition is nowadays a research field of high interest. One of the challenges of this area lies in the segmentation of the species vocalizations. Recordings acquired in natural habitats are contaminated with the sounds emitted by other species and different kinds of background noise. If the data(More)
