Stationary and Mobile Target Detection using Mobile Wireless Sensor Networks

, 2010
In this work, we study the target detection and tracking problem in mobile sensor networks, where the performance metrics of interest are probability of detection and tracking coverage, when the target can be stationary or mobile and its duration is ...

Detection of image structures using the Fisher information and the Rao metric [PDF]

, 2004
In many detection problems, the structures to be detected are parameterized by the points of a parameter space. If the conditional probability density function for the measurements is known, then detection can be achieved by sampling the parameter space ...

Confidence Probability versus Detection Probability [PDF]

, 2005
In a discovery sampling activity the auditor seeks to vet an inventory by measuring (or inspecting) a random sample of items from the inventory. When the auditor finds every sample item in compliance, he must then make a confidence statement about the whole inventory.

Decision Fusion with Unknown Sensor Detection Probability

, 2013
In this correspondence we study the problem of channel-aware decision fusion when the sensor detection probability is not known at the decision fusion center.

Comparing the costs and detectability of bobcat using scat‐detecting dog and remote camera surveys in central Wisconsin

Wildlife Society Bulletin, 2015
Determining cost‐effective field methods for detecting carnivores is critical for effective survey and monitoring studies. As the bobcat (Lynx rufus) undergoes range expansion in the northern and eastern United States, field methods may be useful for ...

Distributed Detection over Random Networks: Large Deviations Performance Analysis

, 2010
We study the large deviations performance, i.e., the exponential decay rate of the error probability, of distributed detection algorithms over random networks.

Tree stocking affects winter bird densities across a gradient of savanna, woodland, and forest in the Missouri Ozarks

Wildlife Society Bulletin, 2013
Savanna and woodland were historically prevalent in the midwestern United States, and managers throughout the area are currently attempting to restore these communities.

Trade‐offs associated with occupancy models in a multispecies grassland plant population study

Ecosphere, 2022
Occupancy models have been underused in multispecies plant studies. We evaluated the effectiveness of occupancy models to document impacts of management on grassland plant species populations in a pilot study.
