Propagation behavior of orbital angular momentum in vector anomalous vortex beams under maritime atmospheric turbulence

open access: yesFrontiers in Physics, 2023
This study explores the propagation properties of orbital angular momentum (OAM) carried by a vector anomalous vortex beam (VAVB) in maritime atmospheric turbulence, utilizing the Rytov approximation.

Shirking, Standards and the Probability of Detection [PDF]

open access: yesSSRN Electronic Journal, 2015
ABSTRACTBy relaxing the common efficiency wage assumption of exogenous shirking detection probabilities, we demonstrate how standards and efficiency wages are related. In a more general setting where the probability of detection depends upon the equilibrium effort level of non‐shirkers, we show that the uniformly positive (negative) supply‐side ...

Comparison of semiautomated bird song recognition with manual detection of recorded bird song samples

open access: yesAvian Conservation and Ecology, 2017
Automated recording units are increasingly being used to sample wildlife populations. These devices can produce large amounts of data that are difficult to process manually.

Habitat models to predict wetland bird occupancy influenced by scale, anthropogenic disturbance, and imperfect detection

open access: yesEcosphere, 2017
Understanding species–habitat relationships for endangered species is critical for their conservation. However, many studies have limited value for conservation because they fail to account for habitat associations at multiple spatial scales ...

Modeling detection probability to improve marsh bird surveys in southern Canada and the Great Lakes states

open access: yesAvian Conservation and Ecology, 2016
Marsh birds are notoriously elusive, with variation in detection probability across species, regions, seasons, and different times of day and weather.

Effects of camera‐trap placement and number on detection of members of a mammalian assemblage

open access: yesEcosphere, 2021
A central goal in camera‐trapping (CT) studies is to maximize detection probability and precision of occupancy estimates while minimizing the number of CTs to reduce equipment and labor costs.

Filter Bank Multi-carrier Waveform Design for Low Probability of Intercepting Joint Radar and Communication System

open access: yesLeida xuebao, 2023
Cyclic prefixes in joint radar and communication systems based on Orthogonal Frequency Division Multiplexing (OFDM) and low probability of interception lead to weak radar echo masking on the battlefield.

Detection probabilities for sessile organisms [PDF]

open access: yesEcosphere, 2016
AbstractEstimation of population sizes and species ranges is central to population and conservation biology. It is widely appreciated that imperfect detection of mobile animals must be accounted for when estimating population size from presence–absence data.

Multi-Target Tracking in Multi-Static Networks with Autonomous Underwater Vehicles Using a Robust Multi-Sensor Labeled Multi-Bernoulli Filter

open access: yesJournal of Marine Science and Engineering, 2023
This paper proposes a centralized MTT method based on a state-of-the-art multi-sensor labeled multi-Bernoulli (LMB) filter in underwater multi-static networks with autonomous underwater vehicles (AUVs). The LMB filter can accurately extract the number of
