For cars or trucks on the verge of roll-over, the boundary between stability and instability occurs when the vehicle balances on two wheels on the same side. In this work, the open-loop steering servo of an off-road type vehicle is used in a closed-loop balance control system that actuates the front steering angle so that the vehicle self-balances and drives on two wheels. A nonlinear vehicle m...

The urban planning process is complex, involving social, economic, environmental, and political systems. Knowledge of how these systems interact the domain professional planners. Advances in artificial intelligence (AI) present planners with a ripe opportunity to critically assess their approaches explore new data collection, analysis, methods can augment understanding places as they seek antic...

This paper addresses the problem of recovering accurate 3D geometry from a 4 degree of freedom stereo robot head. We argue that successful implementation of stereo vision in a real world application will require a self tuning system. This paper describes a statistical framework for the combination of many sources of information for the calibration of a stereo camera system which would allow con...

We present a case of a 45-year-old patient who reported bleeding hemorrhoids. He had grade II hemorrhoids and was found to have a circumferential leukoplakic lesion at the anal verge. The patient had no symptoms of leukoplakia. The hemorrhoids were ablated with an Ellman radiowave device. Histological findings of the incised lesion from the verge showed hyperkeratosis and acanthosis extending c...

Teachers of programming are lucky in that they do not have to do the same thing every year. Programming is still an evolving discipline, with new ideas coming forward at a steady pace. Some of those ideas can be incorporated into the course, some even at the introductory level. Object-oriented programming is one of those ideas. There is no reason to believe that it will be the last, or that it ...

Managing road verges to promote diverse and flower-rich plant communities has been proposed mitigate the decline of pollinating insects caused by loss natural semi-natural habitat. There is, however, a concern that can be ecological traps for pollinators as might attracted habitat where there is risk they are killed traffic. Therefore, we investigated combined effects traffic intensity flowerin...

Questions How has exotic plant species richness and composition changed in adjacent to a montane road verge over 10-year period? Are verges conduits of species’ dispersal into adjacent, undisturbed hinterland? Location Montane grassland, Maloti-Drakensberg Transfrontier Conservation Area, South Africa. Methods We surveyed hinterland transects (25 × 2 m; N = 80) across an elevational gradient 1,...

OBJECTIVE To assess oncologic outcome of patients treated by conservative radical surgery for tumors below 5 cm from the anal verge. SUMMARY BACKGROUND DATA Standard surgical treatment of low rectal cancer below 5 cm from the anal verge is abdominoperineal resection. METHODS From 1990 to 2003, patients with a nonfixed rectal carcinoma at 4.5 cm or less from the anal verge and without extern...
