To analyze the influence of distance between tunnels at bridge-tunnel junction in mountainous area on driving safety under crosswind, a vehicle dynamics model is established by Carsim software. Under conditions different speeds (60km/h, 80km/h and 100km/h), wind scales (level 6–9) three alignment combinations (tunnel-straight road-tunnel, tunnel-curving tunnel-the combination straight curves ro...

If our lives were truly horrible and the prospects of their getting better hopelessly dim, we might not want to continue. Fortunately, most people are not in such dire straights. Most of us, as we say, " want to live " (henceforth, to survive). Not only do we want to survive, but under normal, relatively favorable circumstances most of us, it seems, knows well enough what it would mean to survi...

Area coverage is a type of path planning that is concerned with finding a pattern of movement that will result in coverage of all parts of an area. Most area coverage planning algorithms assume that the robot can maintain a track over the ground that will result in full coverage in obstacle free areas. This is easily done if the robot can be precisely controlled or has sufficient sensor capabil...

In short track speed skating, the relay exchange provides an additional strategic component to races by allowing a team to change the skater involved in the pack race. It is thought that during this period of the race, time can be gained or lost due to the execution of the relay exchange. However, the only temporal measurement reported in short track speed skating is lap time, of which the rela...

PURPOSE The hypothesis that drivers with homonymous hemianopia (HH) would take a lane position that increased the safety margin on their blind side was tested with a driving simulator. METHODS Twelve participants with HH (six right HH and six left; nine men; mean age, 50 years; range 31-72), and 12 matched current drivers with normal vision (NV) each completed approximately 120 minutes of sim...

The Canadian Light Source (CLS) is now under construction. It will be a third generation source capable of producing photon beams for a variety of research applications. The CLS has four principal components: a 250 MeV linac, a full energy booster, a storage ring, and an array of beam lines serving interests ranging from infrared light to hard x-rays. The 2.9 GeV storage ring has a compact desi...

Executive functions are a set of high cognitive abilities that control and regulate other functions and behaviors and are crucial for successful adaptation. Deficits in executive functions are frequently described in developmental disorders, which are characterized by disadaptive behavior. However, executive functions are not widely examined in individuals with intellectual disability. The pres...

This paper presents a stochastic grammar for finegrained 3D scene reconstruction from a single image. At the heart of our approach is a small number of grammar rules that can describe the most common geometric structures, e.g., two straights lines being co-linear or orthogonal, or that a line lying on a planar region etc. With these grammar rules, we re-frame single-view 3D reconstruction probl...

BACKGROUND Visual impairment associated with central field loss may make vehicle control more difficult due to the degraded view of the road. We evaluated how central field loss affects vehicle control in a driving simulator. METHODS Nineteen participants with binocular central field loss (acuity 6/9 to 6/60) and 15 controls with normal vision drove 10 scenarios, each about eight to 12 minute...

Advice about the optimal coordination pattern for an individual speed skater to reach their optimal performance, could well be addressed by simulation and optimization of a biomechanical model of speed skating. But before getting to this optimization approach one needs a model that matches observed behavior. In this paper we present a simple 2-dimensional model of speed skating on the straights...
