A Domain-Based Model for Identifying Regional Collision Risk and Depicting Its Geographical Distribution

open access: yesJournal of Marine Science and Engineering, 2023
In recent years, the increasing volume and complexity of ship traffic has raised the probability of collision accidents in ports, waterways, and coastal waters. Due to the relative rarity of collision accidents, near misses have been used in the research

Velocity/Position Integration Formula (II): Application to Inertial Navigation Computation

open access: yes, 2012
Inertial navigation applications are usually referenced to a rotating frame. Consideration of the navigation reference frame rotation in the inertial navigation algorithm design is an important but so far less seriously treated issue, especially for ...

Torchlight Navigation

open access: yes2010 20th International Conference on Pattern Recognition, 2010
A common computer vision task is navigation and mapping. Many indoor navigation tasks require depth knowledge of flat, unstructured surfaces (walls, floor, ceiling). With passive illumination only, this is an ill-posed problem. Inspired by small children using a torchlight, we use a spotlight for active illumination.

Bottom-up retinotopic organization supports top-down mental imagery [PDF]

open access: yes, 2013
Finding a path between locations is a routine task in daily life. Mental navigation is often used to plan a route to a destination that is not visible from the current location. We first used functional magnetic resonance imaging (fMRI) and surface-based

Learning navigation – Learning with navigation. A review [PDF]

open access: yesSICOT-J, 2017
The goal of this review paper is to retrieve from the existing literature relevant information (1) about the learning curve of the currently existing navigation systems and (2) about the use of navigation system for teaching orthopaedic procedures. All studies reporting on the learning curve of navigation systems support the hypothesis that computer ...
