In this paper, we present a real application system based on wireless sensor network (WSN) for fence surveillance which is implemented on our development platform for WSN, called ANTS (An evolvable Network of Tiny Sensors). Our system, called the WFS system, is expanded to connect and control a robot (UGV/UAV) and a camera sensor network for the purpose of fence surveillance. Two kinds of senso...

—The evaluation of appropriate sampling methodologies is critical for accurately determining the distribution and status of herpetofaunal populations. We report the results of a year-long drift fence study, using multiple trap types (large pitfall traps, small pitfall traps and funnel traps), of a species-rich herpetofaunal community (59 species) surrounding an isolated wetland in the southeast...

Roads affect animals in three adverse ways. They act as barriers to movement ('fence effect'), enhance mortality due to collisions with traffic, and decrease habitat size. We study the relative importance of the first two effects using a spatially explicit individual-based model of population dynamics. We discuss our results with respect to the suitability of fences along roads as a measure to ...

Previous work has shown that African elephants Loxodonta africana will avoid African honeybees Apis mellifera scutellata. Here we present results from a pilot study conducted to evaluate the concept of using beehives to mitigate elephant crop depredation. In Laikipia, Kenya, we deployed a 90-m fence-line of nine inter-connected hives, all empty, on two exposed sides of a square two-acre farm th...

The most important part of recent grassland tenure reforms in Inner Mongolia has been to divide the collective grassland to household level, then fence and enclose grassland. Fencing is a form of strongest signal of private property right and aims to exclude overboundary grazing, attempting to solve “tragedy of the commons” from open access. Fencing gives herders a “user right”, though ownershi...

Tourists have become active mobile technology users while on route. They request information anytime, anywhere, so it has to be personalized to better satisfy their needs. This paper presents a Contextual Geofencing Mobile Tourism Service that proactively sends push based notifications to visitors ́ mobile devices according to their context. These notifications are linked to concrete areas and t...

limited by the timing of new tiller development. Development of new tillers in smooth bromegrass is largely Smooth bromegrass (Bromus inermis Leyss) is poorly adapted to determinant, with synchronized elevation and elongamanagement-intensive rotational grazing because of slow and limited tion of new apical meristems above the soil surface regrowth potential. In an effort to discover germplasm w...

A new code for the design of the guard fence performances was implemented and issued in April 1999 in Japan. The prescribed performances of the new code are: i) prevention of derail, ii) safety of occupant, iii) leading vehicles to road, and iv) prevention of spreading out the broken pieces. In the new code, the full-scale experiment for checking the performances of guard fences is required in ...

Virtual fencing technology uses a neckband-mounted device to deliver an audio cue when animal nears virtual boundary that is set via global positioning system, followed by electrical stimulus if it crosses the boundary. The flexibility offered this could revolutionize grazing management on dairy farms, but its application and effects lactating cattle have not been assessed. This experiment repo...
