A method for detecting drivers’ intentions is essential to facilitate operating mode transitions between driver and driver assistance systems. We propose a driver behavior recognition method using Hidden Markov Models (HMMs) to characterize and detect driving maneuvers and place it in the framework of a cognitive model of human behavior. HMM-based steering(More)
This paper describes an experimental study concerning an evaluation of advanced driving-assistance systems using methods for estimating workload levels. The effects of such systems on drivers’ mental workload and driving performance were measured experimentally using the driving simulator. Six subjects were instructed to drive the simulator in a highway(More)
We evaluated the efficacy of polymyxin B-immobilized fiber (PMX-F) on organ dysfunction using a rat cecal ligation and perforation (CLP) model. Fifteen-week-old Sprague-Dawley rats (n = 21) were divided into three groups. For a PMX group, n = 7, peritonitis was induced by CLP. After 24 hours from CLP, endotoxin adsorption was performed for 1 hour with a(More)
