Chronic sleep loss and associated sleepiness and daytime impairments in adolescence are a serious threat to the academic success, health, and safety of our nation's youth and an important public health issue. Understanding the extent and potential short- and long-term repercussions of sleep restriction, as well as the unhealthy sleep practices and environmental factors that contribute to sleep ...

Event-related brain dynamics of electroencephalographic (EEG) activity in a continuous compensatory tracking task (CTT) and in a continuous driving simulation were analyzed by independent component analysis (ICA) and time-frequency techniques. We showed that changes in the level of subject performance are accompanied by distinct changes in EEG spectrum of a class of bilateral posterior independ...

Driver impairment due to fatigue induced drowsiness is a significant cause of vehicle collisions. One countermeasure that is currently being implemented is Fatigue Warning Systems (FWS) to alert drivers that are drowsy. Behavioural adaptation of drivers to a FWS was evaluated in a closed track study. Thirty-two drivers completed two lengthy overnight drives, separated by one week, with half the...

As feature size shrinks, the dominant component of power consumption will be leakage. As caches represent a considerable fraction of area for many platforms, from embedded to highly paralleled systems, cache leakage control continues to become a critical issue. Drowsy cache technique is a state-preserving technique which reduces leakage by pulling down the voltages on selected lines. To exploit...

Detection of drowsiness based on extraction of IMF’s from EEG signal using EMD process and characterizing the features using trained Artificial Neural Network (ANN) is introduced in this paper. Our subjects are 8 volunteers who have not slept for last 24 hour due to travelling. EEG signal was recorded when the subject is sitting on a chair facing video camera and are obliged to see camera only....

the relation between serum osmolality, glucose, sodium, bicarbonate, arterial ph, bun and level of consciousness was studied in 189 patients with diabetic ketoacidosis (dka). there was much overlap between all laboratory values among various groups, even when there was a statistically significant difference. to find a better predictor, we defined a new factor as serum osmolality/arterial ph. th...
