The growing number of traffic accidents in recent years has become a serious concern to society. Accidents caused by driver’s drowsiness behind the steering wheel have a high fatality rate because of the marked decline in the driver’s abilities of perception, recognition, and vehicle control abilities while sleepy. Preventing such accidents caused by drowsiness is highly desirable but requires ...

OBJECTIVE A pair of simulated driving experiments studied the effects of cognitive load on drivers' lane-keeping performance. BACKGROUND Cognitive load while driving often reduces the variability of lane position. However, there is no agreement as to whether this effect should be interpreted as a performance loss, consistent with other effects of distraction on driving, or as an anomalous per...

The dynamics of the magnetization reversal process in a nanosized permalloy film by the pure spin current (PSC) injection is analyzed. We have performed micromagnetic simulation based on the Landau-Lifshitz equation taking into account both the relaxation term and spin transfer torque term caused by the PSC. PSC is injected into the permalloy from a side of the film. We compare the magnetizatio...

Evaluating the effectiveness and benefits of driver assistance systems is crucial for improving the system performance. In this paper, we propose a novel framework for testing and evaluating lane departure correction systems at a low cost by using lane departure events reproduced from naturalistic driving data. First, 529,096 lane departure events were extracted from the Safety Pilot Model Depl...

Background The tibial cut referenced to the center of the intercondylar eminence often leads to varus malalignment in the presence of preexisting proximal tibia vara. The purpose of this study was to investigate the effect of lateralization of the lateral tibial plateau reference point (based on the amount of proximal tibia vara) on the postoperative coronal plane alignment. Methods In this p...

The incidence of the four main types of axis deviation in each diagnostic group of congenital malformations of the heart was found by an examination of 2,752 electrocardiograms from the Harriet Lane Home Cardiac Clinic. Records from patients with dextrocardia or dextrarotation of the heart, and those with complete bundle branch block were excluded. The precordial and unipolar limb leads in the ...

Objective: The aim of this study was to compare continuous versus bandwidth haptic steering guidance in terms of lane-keeping behavior, aftereffects, and satisfaction. Background: An important human factors question is whether operators should be supported continuously or only when tolerance limits are exceeded. We aimed to clarify this issue for haptic steering guidance by investigating costs ...

The sliding-mode controller (SMC) for the lateral motion control problem of Four Driving-Steering Wheels (4DW/SW) vehicle is presented in this paper. The lane centerline tracking is the main control performance. The dynamic model of the vehicle has been taken into account. Closed-loop robustness to uncertainties is achieved. The lane centerline tracking is achieved using look-ahead techniques. ...

BACKGROUND Driver fatigue as a leading cause of death in the transportation industry can impair the driving performance in long-distance driving task. Studies on the links of driver subjective fatigue and the bus lateral position are still an exploratory issue that requires further investigation. This study aimed to determine the correlation between the driver subjective fatigue and the bus lat...

46 participants (24 younger and 22 older) completed at least one out of four simulated drives designed to test the effectiveness of an Adaptive Lane Deviation Warning (LDW) system, and they drove through both a warnings-on and warnings-off version of each drive. Findings showed that LDW was effective in reducing reaction time for lane deviation corrections for both older (by 1.2 seconds) and yo...
