Alarm timing for a forward collision warning system plays an important role in system effectiveness. It is necessary to determine the appropriate alarm timing by considering a driver’s response to not only true alarms but also how drivers respond when an alarm should have been issued but was not (missed alarms) to evaluate both the increased system effectiveness and decreased over-reliance on t...

In general, the scene change for video indexing could be detected by using an appropriate threshold. However, the single fixed threshold value used in previous researches cannot perform well for all videos equally. In this paper, we propose a dynamic threshold method(DTM) in order to improve the performance of the scene change detection. The proposed method utilizes variable parameters obtained...

We consider a continuously observable process, which behaves like a standard Brownian motion up to a random time τ1, and as a Brownian motion with a known drift after τ1. At a stopping-time τ2 that happens after the time τ1, an observable event occurs. We address the problem of detecting the change in the system’s behaviour prior to the occurrence of the observable event. In particular, our for...

abstract background : today, as many as 1.5 million americans use ventilators once in a year. .response to mechanical ventilation alarms remains to be one of the most challenging tasks facing physicians, nurses or other medical personnel in the icu. in the present study we aimed to compare the response times to “vocal alarms” and “visual or audible ones”. methods : in the present study we devel...

This paper presents a case-study for the optimization, the monitoring and the automatic control of a refrigeration system in a commercial store. The existing controllers were replaced by Omron temperature controllers, connected to an industrial network and linked to a central computer for data monitoring and temperature control using a LabView software. In case of an alarm occurrence, this syst...

The proper handling of alarms is crucial to automated process control. In practice, many alarms are only distractive and do not represent a fault situation. Here a toolbox, that uses an expert system called LARA, is proposed that aims to reduce the occurrence of so-called nuisance alarms. It is based on a signal classification scheme to propose suitable alarm handling algorithms according to th...

The purpose of this article is to describe the current state-of-the-art regarding the co-occurrence of the anxiety disorders and chronic pain. First, we describe the core characteristics of chronic pain and its co-occurrence with the anxiety disorders. Second, we review data on the prevalence of co-occurrence. Third, we describe the mutual maintenance and shared vulnerability models, both of wh...
