We have developed a non-contact method of monitoring sleep-wake status using millimeter-wave radar for body movement while in bed to measure sleeps daily life continuously. Using both and Actigraph, which been proven sleep studies, we measured the movements two subjects week. multiple regression analysis with Actigraph scoring as supervisory values, derived radar-specific algorithm based on Col...

Although 12-step literature posits inconsiderate behaviors to characterize alcoholics and addicts, there is little data to support this association among adolescent populations. Using a matched-pair study design with 579 youth aged 14-18 (52% female, 30% minority), a significant, dose-response relationship was found between greater alcohol and drug use severity and increased likelihood of drivi...

Introduction Imagine, for a second, a doorman that behaves as automatic doors do. He does not acknowledge you when you pass by, or approach. He gives no hint which door can or will open—until you wander within 10 feet of the door, whereupon he flings the door wide open. If you arrived after hours, you might stand in front of the doors for awhile before you understood that the doors are locked, ...

Driving under the influence of substances (DUI) other than alcohol has been the subject of increasing interest over the past few decades (Schulze et al., 2012). As with alcohol, research has shown that drug intake increases the risk of road traffic accidents (Elvik, 2013; Schulze et al., 2012; Verstraete & Legrand, 2014). Intervention in this area is a priority. A key factor for deterring DUI i...

In this article I examine the constraints that skeptical hypotheses must satisfy in order to be used to raise significant skeptical challenges. I argue that skeptical hypotheses do not have to be logically, metaphysically or epistemically possible. They only need to depict scenarios that are subjectively indistinguishable from the actual world and must provide some indication of how subjects ca...

Invariant assertions play an important role in the analysis and documentation of while loops of imperative programs. Invariant functions and invariant relations are alternative analysis tools that are distinct from invariant assertions but are related to them. In this paper we discuss these three concepts and analyze their relationships. The study of invariant functions and invariant relations ...
