Not afraid of the big bad wolf: calls from large predators do not silence mesopredators
Wildlife Biology, Volume 2024, Issue 6, November 2024.Large predators are known to shape the behavior and ecology of sympatric predators via conflict and competition, with mesopredators thought to avoid large predators, while dogs suppress predator activity and act as guardians of human property. However, interspecific communication between predators has not been well‐explored and this assumption of ...

Emitter locating performance analysis for multilateration system
, 2014 Multilateration or time-delay of arrival estimation can provide three dimensional (3D) emitter locating suitable for airborne targets. This is an advantage over AOA based methods which could provide only two dimensional (2D) emitter locating.

Characterization of an Ultrasonic Local Positioning System for 3D Measurements
Sensors, 2020 Indoor location and positioning systems (ILPS) are used to locate and track people, as well as mobile and/or connected targets, such as robots or smartphones, not only inside buildings with a lack of global navigation satellite systems (GNSS) signals but

Improved Self-Calibration of a Multilateration System Based on Absolute Distance Measurement
Sensors, 2020 Multilateration tracking systems (MLTSs) are used in industrial three-dimensional (3D) coordinate measuring applications. For high-precision measurement, system parameters must be calibrated properly in advance.

Regionalism in a Multilateral World [PDF]
Journal of Political Economy, 1998 Recent regional initiatives have been addressed from a Vinerian perspective of trade creation and trade diversion. This is true of both policy‐oriented economists, who tend to be critical of the initiatives, and theorists, who have added dynamic and gametheoretic elements to the Vinerian structure. This paper describes the stylized facts of much recent

Y-Chromosome Haplotype Origins via Biogeographical Multilateration
, 2014 Current Y-chromosome migration maps only cover the broadest-brush strokes of the highest-level haplogroups. Existing methods generalize geographic patterns based on large population genetic frequency and diversity.

Method for Rapid Judgment of Faulty Stations of Multilateration System
MATEC Web of Conferences, 2015 An airport surface multilateration system based on the time difference of arrival (TDOA) positioning principle establishes equations to calculate the position of target through utilizing the TDOA of targets’ answering signals to the ground receiving ...
