Despite long-standing knowledge of the benefits riparian buffers for mitigating nonpoint source pollution, many streams are unprotected by buffers. Even landowners who understand ecological values mow vegetation to streambank. Do trends in rural conditions reflect development forest science? What motivates residential management actions? Using high-resolution orthoimagery, we quantified and bet...

Hand operation accompanied with any combination of large forces, awkward positions and repetition may lead to upper limb injury or illness and may be exacerbated by vibration. Commercial lawn mowers expose operators to these factors during actuation of hand controls and therefore may be a health concern. A nontraditional lawn mower control system may decrease upper limb illnesses and injuries t...

Understanding and designing appropriate educational youth safety programs for the Amish requires an appreciation of their history, their distinctiveness in an American society built on economic, social and cultural change, and how the Amish themselves have changed over the years. The qualitative research study highlighted in this paper sought to determine culturally and age-appropriate curricul...

Abs t rac t Much of the focus of the research effort in path planning for mobile robots has centred on the problem of finding a path from a start location to a goal location, while minimising one or more parameters such as length of path, energy consumption or journey time. A path of complete coverage is a planned path in which a robot sweeps all areas of free space in an environment in a syste...

Robots are increasingly present in modern industry and also in everyday life. Their applications range from health-related situations, for assistance to elderly people or in surgical operations, to automatic and driver-less vehicles (on wheels or flying) or for driving assistance. Recently, an interest towards robotics applied in agriculture and gardening has arisen, with applications to automa...

Globally, one in three adults has some level of measurable hearing loss, and 1.1 billion young persons are at risk for hearing loss attributable to noise exposure. Although noisy occupations such as construction, mining, and manufacturing are primary causes of hearing loss in adults, nonoccupational noise also can damage hearing. Loud noises can cause permanent hearing loss through metabolic ex...

The navigation systems of commercially available autonomous lawnmowers rely on sensors measuring the magnetic field created by a perimeter wire. Some experimental systems rely on even more expensive sensing devices, like differential GPS or laser tracking systems that help locate the mowers exactly within a yard, but are considered too expensive for a domestic robot. Knowing a mower’s exact pos...

Abstract This paper presents a novel solution of coverage path planning for robotic mowing applications. The algorithm is based on the Boustrophedon motions and rapid Voronoi diagram. coordinate conversion sweeping vector defined by minimum bounding box travel paths are designed to reduce computational cost execution time compared conventional heuristic methods. tracked controlled via dynamic f...
