The Nike KrF laser, with its very uniform focal distributions, has been used at intensities near 1014 W/cm2 to launch shock waves in polystyrene targets. The rear surface visible light emission differed between clear CH targets and targets with a thin (125 nm) Al coating on the rear side. The uncoated CH targets showed a relatively slowly rising emission followed by a sudden fall when the shock...

The large number of rear end collisions due to driver inattention has been identified as a major automotive safety issue. In this paper, we describe a 3-phase vehicle tracking methodology with a single moving camera mounted on the driver’s automobile as input for use in detecting rear vehicles on highways and city streets. In the first phase, vehicle detection, a rear vehicle is detected by sym...

Rapid Prototyping is used in embedded systems design as a means to reduce development time and costs. At an early stage in the development cycle, the specification is implemented in a working protoype, which can be used to test the specification and, in real-time systems, also the timing constraints. The REAR Rapid Prototyping Environment was built as an adaptable target platform for embedded r...

Modern climate change is producing poleward range shifts of numerous taxa, communities and ecosystems worldwide. The response of species to changing environments is likely to be determined largely by population responses at range margins. In contrast to the expanding edge, the low-latitude limit (rear edge) of species ranges remains understudied, and the critical importance of rear edge populat...

Aerodynamic drag is an important factor in vehicles fuel consumption. Pressure drag which is the main component of total drag is a result of boundary layer separation from vehicle surface. Flow control methods are applied to avoid or at least delay separation. Depending upon whether these methods consume energy to control the flow or not, they are called active or passive control methods. In th...

Whiplash injuries resulting from rear impacts are one of the most important injury categories with regard to long-term consequences. Most rear impacts lead to no injury or to symptoms that are temporary. Impacts where the duration of symptoms differs need to be separated in analyses in order to isolate representative rear impact conditions in which more long-lasting whiplash injuries occur. The...
