We propose a technique for extracting and remove a fence region in a still image. The proposed method uses the fact that the fence region consists of periodic and parallel straight lines in a space. Characteristic of parallel and periodic lines in an image is used for the fence parallel to the image plane. Property of a projection of periodic parallel lines in a space is used for the other case...

In a poem titled “Fence or Ambulance” written more than one hundred years ago, Joseph Malins described the policy dilemma a city faced in tackling the rising morbidity and mortality from accidental falls from a dangerous cliff. The 2 policy options considered included building a strong fence around the edge of the cliff or raising funds to support an ambulance down in the valley. The city initi...

This paper presents a novel approach for orienting an object on conveyer belt utilizing an Active Fence. The Active fence was implemented with low cost sensory system used for tracking the contact/collision force generated from interaction between the Active Fence and the object. A generalized mechanical model of the collision/contact event is developed and basic relations between impact signat...

A fence post design, when viewed on a plot of index of refraction versus film thickness, has thin (usually of equal thickness) high-index posts that stand above a broad low-index ground. Monitoring fence post and related posthole designs offers error compensation and error reduction. There tend to be two or more extrema within the optical monitoring trace of each layer between the fence posts t...

Fruit and vegetable intake among children is inadequate. Garden-based nutrition education programs may offer a strategy for increasing fruit and vegetable intake in children. A 12-week pilot intervention was designed to promote fruit and vegetable intake among 4th to 6th grade children (n=93) attending a YMCA summer camp. Children participated in garden-based activities twice per week. Weekly e...

Evolutionary game theory is one of the key paradigms behind many scientific disciplines from science to engineering. In complex networks, because of the difficulty of formulating the replicator dynamics, most of the previous studies are confined to a numerical level. In this paper, we introduce a vectorial formulation to derive three classes of individuals' payoff analytically. The three classe...

A combined blast fence is introduced in this paper to improve the solid blast fences and louvered ones. Experiments of the jet engine exhaust flow (hereinafter jet flow for short) field and tests of three kinds of blast fences in two positions were carried out. The results show that the pressure and temperature at the centre of the jet flow decrease gradually as the flow moves farther away from...

Concentrated herbivory by elk (Cervus elaphus) can degrade vegetative communities and alter ecosystem processes. Areas severely damaged by elk are commonly protected with woven wire fence, which can exclude other animals. Complete exclusion and prevention of large mammal herbivory might not always be necessary to restore vegetative communities. We designed and evaluated a simple fence that excl...

Demand for commercial bee (Apis mellifera) services recently has increased, resulting in greater use of mobile apiaries for crop pollination. When commercial apiaries are moved into areas occupied by black bears (Ursus americanus), conflicts between beekeepers and bears sometimes occur. Commercial pollination often involves moving apiaries among agricultural fields, and, thus, permanent fencing...
