background while cyclists and pedestrians are known to be at significant risk for severe injuries when exposed to road traffic accidents (rta) involving trucks, little is known about rta injury risk for truck drivers. objectives the aim of this study was to analyze the injury severity in truck drivers following rtas. patients and methods our local accident research unit prospectively documented...

We give a mathematical description of the initial stage both axles skidding for wheeled vehicle on bend that arises in case blocking or slipping wheels one its axles. It is shown within framework Zhuravlev’s model friction, which takes into account moments spinning friction (they appear as result interaction with reference plane), less than Coulomb model.

In this paper, some results concerning the k-truck problem are produced. First, the algorithms and their complexity concerning the off-line k-truck problem are discussed. Following that, a lower bound of competitive ratio for the on-line k-truck problem is given. Based on the Position Maintaining Strategy (PMS), we get some new results which are slightly better than those of [1] for general cas...

BACKGROUND HIV prevention programmes for truck drivers form part of the HIV control efforts, but systematic data on the outputs and cost of providing such services in India are not readily available for further planning and use of resources. METHODS Detailed cost and output data were collected from written records and interviews for 2005-2006 fiscal year using standardized methods at six samp...

We address the multi container loading problem of a company that has to serve its customers by first putting the products on pallets and then loading the pallets into trucks. We approach the problem by developing and solving integer linear models. To be useful in practice, our models consider three types of constraints: geometric constraints, so that pallets lie completely inside the trucks and...

Multi-purpose forest fire fighting vehicles include a combination of equipment such as high-pressure water pump, create corridor insulation cutting machine, vacuum and high wind speed bowling extinguish the sandblast apparatus that is mounted on URAL 4320 active three axles vehicle. When installing vehicles, increases load, affecting vehicle's load distribution, angularity, stability. Therefore...

background: long distance truck drivers (ldtds) and their sexual health risk behaviors have been associated with greater prevalence of sexually transmitted infections (stis), hiv and hepatitis virus transmission. however, there is no information about iranian ldtds' high-risk behaviors. the aim of this investigation was to estimate the prevalence of high-risk behaviors in iranian ldtds. methods...

Neural networks are a biologically motivated problem-solving paradigm that has proven successful in robustly solving a variety of problems. This paper describes another biologically motivated paradigm, namely genetic programming, which can also solve a variety of problems. This paper explains genetic programming and applies it to two well-known benchmark problems from the field of neural networ...
