Quantifying the Availability of Vertebrate Hosts to Ticks: A Camera-Trapping Approach
The availability of vertebrate hosts is a major determinant of the occurrence of ticks and tick-borne zoonoses in natural and anthropogenic ecosystems and thus drives disease risk for wildlife, livestock, and humans. However, it remains challenging to quantify the availability of vertebrate hosts in field settings, particularly for medium-sized to large-bodied mammals. Here, we present a method...
متن کاملA new interval approach for setting the distance relay zones to achieve perfect selectivity and maximum sensitivity
In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

متن کاملTime‐lapse camera trapping as an alternative to pitfall trapping for estimating activity of leaf litter arthropods
Pitfall trapping is the standard technique to estimate activity and relative abundance of leaf litter arthropods. Pitfall trapping is not ideal for long-term sampling because it is lethal, labor-intensive, and may have taxonomic sampling biases. We test an alternative sampling method that can be left in place for several months at a time: verticallyplaced time-lapse camera traps that have a sho...
متن کاملReal Time Implementation of a License Plate Location Recognition System Based on Adaptive Morphology
License plate recognition (LPR) by using morphology has the advantage of resistance to brightness changes; high speed processing, and low complexity. However these approaches are sensitive to the distance of the plate from the camera and imaging angle. Various assumptions reported in other works might be unrealistic and cause major problems in practical experiences. In this paper we considered ...
