This paper documents some tests of 802.11b wireless communication technology for vehicle to roadside communication. Data has been collected for a single vehicle communicating with a dedicated roadside antenna. The work is part of a larger effort to benchmark possible throughput of off-the-shelf wireless technologies. The results show that high-speed communication is possible over distances of u...

Plants are the only living organisms which have to suffer a lot from automobile exhaust pollution because they remain static at their habitat. But such roadside plants like Nerium indicum Mill., Boerhaavia diffusa L., Amaranthus spinosus L., Cephalandra indica Naud., and Tabemaemontana divaricata L. can easily avoid the effects of air pollution by altering their physiological pathways pertainin...

ƒ A significant minority of REU reported engaging in specific harm reduction strategies as a result of the introduction of roadside drug testing. BACKGROUND Driving under the influence of illicit drugs and/or alcohol is a significant road safety concern (1-3). Although changes in actual crash risk vary between drugs, all illicit drugs are associated with cognitive and performance effects that a...

The roadside-to-vehicle communication system is an infrastructure network to be deployed along the roads, which is an important part of the vehicular Ad Hoc networks for future intelligent transportation systems. Vehicle position estimation is a key technology for roadside-to-vehicle communication. In this study, a roadside-to-vehicle communication system is proposed where a camera is fixed on ...

BACKGROUND Many argue that prohibition creates more troubles than alternative policies, but fewer than half of American voters support a taxed and regulated market for cannabis. Some oppose a regulated market because of concerns about driving after smoking cannabis. Although a roadside sobriety test for impairment exists, few voters know about it. The widespread use of a roadside sobriety test ...

Switchgrass (Panicum virgatum L.) is a North American grass that exhibits vast genetic diversity across its geographic range. In the Northeastern US, local switchgrass populations were restricted to a narrow coastal zone before European settlement, but current populations inhabit inland road verges raising questions about their origin and genetics. These questions are important because switchgr...

BACKGROUND, AIM AND SCOPE Genetically modified herbicide-tolerant (GMHT) oilseed rape (OSR; Brassica napus L.) was approved for commercial cultivation in Canada in 1995 and currently represents over 95% of the OSR grown in western Canada. After a decade of widespread cultivation, GMHT volunteers represent an increasing management problem in cultivated fields and are ubiquitous in adjacent ruder...
