Visual surveillance is an active research topic in image processing. Transit systems are actively seeking new or improved ways to use technology to deter and respond to accidents, crime, suspicious activities, terrorism, and vandalism. Human behavior-recognition algorithms can be used proactively for prevention of incidents or reactively for investigation(More)
Complete feeding sequences (bite to terminal swallow) were recorded in 11 individuals (Class I occlusions) feeding on apple, banana and biscuit (hard cookie) to establish whether jaw movements characteristic of the stage I transport, chewing, stage II transport and swallowing processes found in non-human mammals could be identified in man. All participants(More)
The purpose of this project was to provide a toolbox for transit systems with an overview of the procedures and guidelines needed to conduct transit incident investigations. This toolbox does not replace existing federally offered training courses, but rather is intended to assist transit systems in implementing and complying with state requirements and(More)
United States' transit systems did a fairly successful job of safely and securely protecting their facilities and passengers. Until that time, public transit security issues generally dealt only with unruly passengers, fare evasion, vandalism, trespassing, and theft. With the events of 9/11, the public transit bombing attacks in Madrid, and the biological(More)
The intracerebroventricular (icv) administration of 5.0 or 25.0 ng of beta-endorphin or Met-enkephalin causes retrograde amnesia for a shuttle avoidance task ion rats. In both cases, the higher dose was more effective than the lower one. The present results confirm previous similar findings obtained using systemic administrations of these compounds, and(More)
