A technique for the longitudinal control of a platoon of automated vehicles is presented. A nonlinear model is used to represent the vehicle dynamics of each vehicle within the platoon. The controlled vehicle is assumed to be capable of measuring (or estimating) necessary dynamical information from the vehicle immediately in front of it by its on-board sensors. The computer in the vehicle proce...

introduction: following a traumatic brain injury (tbi), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. this study examined the changes in brain concentrations of proinflammatory cytokines il-1, il-6, tnf-α and tgf- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post-in...

This work compares the degradation in driving performance associated with secondary tasks performed with voice-based and visual/manual interfaces, including radio tuning, phone dialing, and more complex tasks involving a sequence of interactions with an in-vehicle computer system. Twenty-one participants drove an instrumented vehicle while performing a combination of car-following, peripheral t...

The most distinct advantage of electric vehicle is in its quick and precise torque generation. We propose two novel traction control techniques of electric vehicle, i.e., the model following control and the optimal slip ratio control. Their effectiveness is demonstrated by using the test vehicle "UOT Electric March".

Maneuvers of a nonholonomic vehicle in a structured dynamic environment are considered. The paper focuses on motion generation and control methods to autonomously perform lane following/changing and parallel parking maneuvers. Lane following/changing involves the tracking of a nominal trajectory in the traac lane, and the generation and tracking of local lane-changing trajectories, for instance...

Older drivers are frequently involved in collisions at intersections. One reason may be inadequate head and eye scanning when approaching the intersection. Prior driving simulator research on scanning at intersections has employed two main methods to guide subjects through the simulated world: auditory instructions similar to GPS navigation and following a lead vehicle. However, these two metho...

over half of all reported traumatic brain injuries are the result of a motor vehicle accident. other then the direct head impact itself, the sheer forces of the accident can cause the brain also to collide against the internal bone of the skull. in fact, when a moving head comes to a quick stop, the brain continues in its movement, striking the interior of the skull. this can cause bruising of ...

Background: The hematopoietic system is sensitive to the adverse effects of ionizing radiation. Cellular therapies utilizing mesenchymal stem cells or vascular endothelial cells have been explored as potential countermeasures for radiation hematopoietic injuries. We investigated cells cultured from amnion                ...

background: in previous studies, the neuroprotective effect of 17&beta-estradiol; in diffuse traumatic brain injury has been shown. this study used ici 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17&beta-estradiol; in traumatic brain injury is mediated by the estrogen receptors. methods: the ovariectomized rats were divided in...

This paper describes a robust approach to real-time model-based visual tracking and servoing for rigid polyhedral objects moving with 3 degrees of freedom. It is recognized that low-level feature segmentation is not infallible. Uncertainty measures enter into all computations to account for varying degrees of confidence in the measured object features. Robust tracking and servoing has been demo...
