Speedy bearings to slacked steering: Mapping the navigation patterns and motions of Viking voyages
PLOS ONE, 2023 Viking sailors ruled the North Atlantic Ocean for about three hundred years. Their main sailing route was the 60° 21’ 55’’ latitude between Norway and Greenland. Although they did not have a magnetic compass, in sunshine they used a sun-compass to determine the geographical north (solar Viking navigation: SVN).

Visibility-Inspired Models of Touch Sensors for Navigation [PDF]
, 2022 This paper introduces mathematical models of \sensors\ for mobile robots based on visibility. Serving a purpose similar to the pinhole camera model for computer vision, the introduced models are expected to provide a useful, idealized characterization of task-relevant information that can be inferred from their outputs or observations.

Dynamic knee alignment and collateral knee laxity and its variations in normal humans
Frontiers in Surgery, 2015 Alignment of normal, arthritic and replaced human knees is a much debated subject as is the collateral ligamentous laxity. Traditional quantitative values have been challenged. Methods used to measure these are also not without flaws.

In-Lab Demonstration of an Underwater Acoustic Spiral Source
Sensors, 2023 Underwater acoustic spiral sources can generate spiral acoustic fields where the phase depends on the bearing angle. This allows estimating the bearing angle of a single hydrophone relative to a single source and implementing localization equipment, e.g.,

Nonlinear Observers Design for Vision-Aided Inertial Navigation Systems [PDF]
, 2021 This paper deals with the simultaneous estimation of the attitude, position and linear velocity for vision-aided inertial navigation systems. We propose a nonlinear observer on $SO(3)\times \mathbb{R}^{15}$ relying on body-frame acceleration, angular velocity and (stereo or monocular) bearing measurements of some landmarks that are constant and known ...
