Glasgow time signals

The Glasgow Coma Scale: time for critical reappraisal?

www.thelancet.com/neurology Vol 13 August 2014 755 in astrocytes. Furthermore, KIR4.1 loss will also occur when oligodendrocytes are lost in the demyelinating process or astrocyte processes are damaged by mechanisms independent of antibody-mediated and complement-mediated immune reactions. Finally, technical issues of immunocytochemistry (eg, use of frozen vs paraffi n sections) and exact stagi...

Short-Time Time-Reversal on Audio Signals

We present an analysis of short-time time-reversal on audio signals. Based on our analysis, we define parameters that can be used to control the digital effect and explain the effect each parameter has on the output. We further study the case of 50% overlap-add, then use this for a real-time implementation. Depending on the window length, the effect can modify the output sound variously, from a...

Real Time Driver’s Drowsiness Detection by Processing the EEG Signals Stimulated with External Flickering Light

The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...

Discrimination of Power Quality Distorted Signals Based on Time-frequency Analysis and Probabilistic Neural Network

Recognition and classification of Power Quality Distorted Signals (PQDSs) in power systems is an essential duty. One of the noteworthy issues in Power Quality Analysis (PQA) is identification of distorted signals using an efficient scheme. This paper recommends a Time–Frequency Analysis (TFA), for extracting features, so-called "hybrid approach", using incorporation of Multi Resolution Analysis...
