Drowsy Caches
On-chip caches represent a sizable fraction of the total power consumption of microprocessors. Although large caches can significantly improve performance, they have the potential to increase power consumption. As feature sizes shrink, the dominant component of this power loss will be leakage. However, during a fixed period of time the activity in a cache is only centered on a small subset of t...
متن کاملDrowsy Driver Identification Using Eye Blink detection
As field of signal processing is widening in various security and surveillance applications, motivated the interest for implementing better application with less complications. A non-intrusive machine vision based concepts is used to simulate Drowsiness Detection System. The system is consisting of web camera which placed in a way that it records driver’s head movements in order to detect drows...
متن کاملCerebral Perfusion in Drowsy and Nondrowsy Individuals
1085 Cerebral Perfusion and Drowsiness—Poudel et al INTRODUCTION Lack of sufficient sleep can increase drowsiness and tendency to fall asleep during the day. Increased sleepiness is often manifested as response slowing, behavioral lapses,1-3 and changes in ocular and facial behaviors including droopy eyes, slow eyelid closure, head nodding, and loss of facial tone.4-6 Although total sleep depri...
متن کاملDrowsy Driver Detection Through Facial Movement Analysis
The advance of computing technology has provided the means for building intelligent vehicle systems. Drowsy driver detection system is one of the potential applications of intelligent vehicle systems. Previous approaches to drowsiness detection primarily make pre-assumptions about the relevant behavior, focusing on blink rate, eye closure, and yawning. Here we employ machine learning to datamin...
متن کاملThe Prevalence and Impact of Drowsy Driving
Studies have documented operator drowsiness, sleepiness, or fatigue as causal or contributing factors in aviation, maritime, and trucking accidents. However, estimates of the prevalence of drowsy drivers on the road and of the proportion of motor vehicle crashes that involve drowsy drivers vary widely. This study presents new estimates of the prevalence of drowsy drivers on U.S. roads and of th...
