In this paper, independent component analysis (ICA) is used for blind source separation of biomedical signals. Visual and quantitative tests of the ability of ICA to separate signals were performed using a fast ICA algorithm. Results obtained from simulated and FECG signals show that the ICA performance using the whitening matrix of the mixed signals was superior to that of random initial weights.

The task of choosing the appropriate classifier for a given scenario is not an easy-to-solve question. First, there increasingly high number algorithms available belonging to different families. And also lack methodologies that can help on recommending in advance family certain type datasets. Besides, most these classification exhibit degradation performance when faced with datasets containing ...

An automated method to assess the fetal physiological development is introduced which uses the component intervals between fetal cardiac valve timings and the Q-wave of fetal electrocardiogram (fECG). These intervals were estimated automatically from one-dimensional Doppler Ultrasound and noninvasive fECG. We hypothesize that the fetal growth can be estimated by the cardiac valve intervals. Thi...

Objective This roundtable will provide a forum for the syndromic surveillance Community of Practice (CoP) to learn about activities of the BioSense 2.0 User Group (BUG) workgroups that address priority issues in syndromic surveillance. It will be an opportunity to discuss key challenges faced by public health jurisdictions in the era of Meaningful Use and identify further needs and best practic...

UNLABELLED Couplings between uterine contractions (UC) and fetal heart rate (fHR) provide important information on fetal condition during labor. At present, couplings between UC and fHR are assessed by visual analysis and interpretation of cardiotocography. The application of computerized approaches is restricted due to the non-stationarity of the signal, missing data and noise, typical for fHR...

The use of tools in data and information quality diagnosis and improvement projects is desirable to automate clerical tasks and in some cases it is mandatory to be effective. In this work we present a toolkit that we developed in the context of the NEAT methodology, that provides a systematic way of assessing Data Quality. The novelty of the proposal is given by the construction of many indepen...

Non-invasive fetal electrocardiograms (FECGs) are an alternative method to standard means of fetal monitoring which permit long-term continual monitoring. However, in abdominal recording, the FECG amplitude is weak in the temporal domain and overlaps with the maternal electrocardiogram (MECG) in the spectral domain. Research in the area of non-invasive separations of FECG from abdominal electro...

Centralized system for fetal home telemonitoring with wireless data transmission based on GSM service and internet is presented in this paper. Cardiotocographic signals are provided by mobile instrumentation which consists of bioelectrical signal recorder and Tablet PC. It enables to support a classical interpretation of cardiotocographic trace by information on fetal electrocardiogram morpholo...
