Examination of selected passive tracking schemes using adaptive kalman filtering
In the past, passive SONAR range tracking systems have used Extended Kalman filters to process nonlinear time-delay measurements. This approach has several flaws due to the inherent divergence problems of Extended Kalman filters. This paper discusses a new approach which uses a prefilter to …

Algorithms for multi-modal human movement and behaviour monitoring
… improvements in the field of automated people tracking using multi-modal infrared (IR) and visible image information. The research question posed is; “To what extent can infrared image information be used to improve visible light based human tracking systems?” Automated passive tracking of …

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches
… and ghost crabs at four study sites using passive tracking plots. My data suggest intraguild predation by raccoons limits ghost crab abundance and that reduced raccoon abundance allowed ghost crab abundance to increase, resulting in a net increase in sea turtle egg predation. These results …

Passive Acoustic Localization and Tracking with Mobile Robots
… sensing onboard mobile robotic platforms in passive bearing-only tracking of surface vessels in the water and in detecting nearby obstacles in aerial systems.</p><p>First, we consider the problem of target tracking with a bearing-only sensor in the presence of merged measurements. Assuming …

Multivalent Programmable Interactions Between Lipid Vesicles: Towards Responsive Soft Materials
… complementary DNA interactions, through passive tracking of diffusive colloidal particles and active microrheology using magnetic tweezers. We observe changes in the structure in response to increased temperature, DNA concentration and aging leading to reduced pore sizes. From a …
