In this paper a new approach to the problem of recognizing the preceding vehicle on highways is presented. The system is based on monocular vision. Since on highways the position of the preceding vehicle in the image varies slowly, its previous and current positions are compared using correlation. Such image processing produces a very clear output, which, at a higher level, allows a simple and ...

Intercontinental transport (ICT) of trace substances normally occurs on timescales ranging from a few days to several weeks. In this paper an extraordinary episode in November 2001 is presented, where pollution transport across the North Atlantic took only about one day. The transport mechanism, termed here an intercontinental pollution express highway because of the high wind speeds, was excep...

Recently, there has been immense interest in using unmanned aerial vehicles (UAVs) for civilian operations. As a result, unmanned aerial systems traffic management is needed to ensure the safety and goal satisfaction of potentially thousands of UAVs flying simultaneously. Currently, the analysis of large multi-agent systems cannot tractably provide these guarantees if the agents’ set of maneuve...

IN TR O D U C TIO N Until recently aggregates were considered inert materials which, when mixed with some cementing agent, served as filler in concrete. This concept is far from reality. Research and experience have demonstrated that aggregates are physically and chemically active in ways that control their serviceability in concrete. Since these materials constitute about 75 per cent of the vo...

The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...

HIGHWAYS OF THE BRAIN White matter is a lot like the highways of the brain. These highways connect different parts of the brain and pass information from one part of the brain to others. The better built the highways are, the easier it is to do things like read and do math. These connections or highways are called tracts, and each tract will connect different parts of the brain. There is a spec...
