The case of a 15-year-old boy, a high-performance motocross rider, who developed bilateral osteochondritis dissecans of the elbow is described. Both lesions were successfully treated by Herbert screw internal fixation.

In this paper we discuss stabilization of a nonholonomic system consisting of a unicycle with rider. We show in particular that one can achieve stability of slow steady vertical motions by imposing a feedback control force on the rider’s limb.

In this paper we test the effect of non-binding defaults on the level of contribution to a public good. We manipulate the default numbers appearing on the decision screen to nudge subjects toward a free-rider strategy or a perfect conditional cooperator strategy. Our results show that the vast majority of our subjects did not adopt the default numbers, but their stated strategy was affected by ...

The Decavitator is a human-powered hydrofoil water vehicle designed for the fastest-possible speed over short distances. Since 1988, numerous versions of the underwater hydro-foil system, control and stability system, and pontoons were built and tested. In its present connguration, the vehicle consists of two kayak-type pontoons, with a central frame supporting the rider and the large air prope...

The use of ATVs both recreationally and in the workplace (particularly on farms in Australia), continue to be major contributors to fatal and serious injuries both in the USA and Australia. This paper firstly presents the findings from the authors’ 2003 study into ATV safety and potential countermeasures [1], and secondly, some 10 years later, leads into the current major test program being und...
