Automated electrocardiogram interpretation for the detection of postoperative junctional ectopic tachycardia at the pediatric intensive care unit

Background: Postoperative junctional ectopic tachycardia (JET) is an arrhythmia associated with increased morbidity and mortality rates in children with congenital heart disease. Developing an automated detection algorithm could aid in early identification and timely treatment of JET.<br/><br/>Methods: A retrospective study was conducted using...

Using machine learning to assess the predictive capabilities of fetal cardiotocography with reference to the time of the measurement relative to time of birth

Abstract—Background: cardiotocography (CTG) has long been used in clinical decision making to help assess the fetus’ condition during pregnancy. However it’s usefulness in the detection of fetal acidosis is debated due to high inter and intraobserver variability and general difficulty in interpreting the signals. The introduction of automatic...

Analysis and Detection of Neural Synchrony in the Prefrontal Cortex

Signal Analysis techniques are routinely used in Neuroscience to interpret raw signals harvested from the Nervous System. From a simple Fourier analysis to more complicated methods such as multiresolution wavelet analysis, such techniques must be used for signal manipulation in order to reach informed conclusions on the measurements taking place...

Small-signal modelling and stability analysis of a traditional generation unit and a virtual synchronous machine in grid-connected operation

The virtual synchronous machine (VSM) concept has emerged as an approach to provide flexible distributed control of power electronic converters interfacing distributed energy resources with the grid. It supports power system operation by providing ancillary services, and facilitates a seamless transition between grid-connected and islanded...

Definition and evaluation of production test validation methods applied to Vx multiphase flow meters

Accurate flow rate measurements are very important in production testing. Originally small and insignificant deviations could propagate in subsequent applications where flow rate data is used as input parameter. Vx multiphase flow meters give much more information compared to conventional test separators. This extra data can be used for extra...
