Maneuvering target tracking is a target motion estimation problem, which can describe the irregular target maneuvering motion. It has been widely used in the field of military and civilian applications. In the maneuvering target tracking, the performance of Kalman filter (KF) and its improved algorithms depend on the accuracy of process noise statistical properties. If there exists deviation be...

A new interacting multiple model (IMM) algorithm using intelligent input estimation (IIE) is proposed for maneuvering target tracking. In the proposed method, the acceleration level for each sub-model is determined by IIE-the estimation of the unknown target acceleration by a fuzzy system using the relation between the residuals of the maneuvering filter and the non-maneuvering filter. The gene...

This paper discusses the maneuvering control algorithm based on all-wheel independent driving and steering control techniques for special purpose 6WD/WS vehicles. The maneuvering control algorithms considering superior dynamic characteristics of high power in-wheel motors and independent steering system are designed to perform driving and steering control, vehicle stability control, and fault t...

Purpose It is well-established that victims and offenders are often the same people, a phenomenon known as the victim-offender overlap, but the developmental nature of this overlap remains uncertain. In this study, we drew from a developmental theoretical framework to test effects of genetics, individual characteristics, and routine-activity-based risks. Drawing from developmental literature, w...

This research examined whether a government-initiated pilot project of mandatory polygraph testing would increase the disclosures made by community-supervised sexual offenders in the United Kingdom. The Offender Managers of 332 pilot polygraph sexual offenders and 303 sexual offenders who were receiving usual community supervision were telephoned quarterly, over a 21-month period, to collect in...

The Draper Laboratory Vorticity Control Unmanned Undersea Vehicle (VCUUV) is the first mission-scale, autonomous underwater vehicle that uses vorticity control propulsion and maneuvering. Built as a research platform with which to study the energetics and maneuvering performance of fish-swimming propulsion, the VCUUV is a self-contained free swimming research vehicle which follows the morpholog...

The di!culty in tracking a maneuvering target in the presence of false measurements arises from the uncertain origin of the measurements (as a result of the observation=detection process) and the uncertainty in the maneuvering command driving the state of the target. Conditional mean estimates of the target state require a computational cost which is exponential with the number of observations ...

Detailed knowledge of the estimation performance for passive tracking of maneuvering targets is of fundamental interest. Therefore, the maximum achievable localization accuracy for maneuvering targets from azimuth measurements as well as from combined azimuth and azimuth rate measurements are calculated in this paper. These targets perform a piecewise curvilinear motion with an unknown number o...

Turning strategies on the Sarcos Treadport, a linear treadmill locomotion interface, are developed and compared in a tight maneuvering task. A rate control strategy employing sidestep is compared to a proportional control strategy employing head gaze and torso trigger. The maneuvering task involves walking down a narrow corridor and avoiding obstacles that are placed at different separations to...

A study is currently underway to better understand and influence the maneuvering characteristics of autonomous underwater vehicles (AUVs). A two-pronged approach, using traditional quasi-steady state-space modeling as well as maneuvering experiments performed in unsteady Reynolds-averaged Navier-Stokes simulations (URANS), has been adopted to provide the greatest possible insight into vehicle m...
