Dynamic Neural‐Model‐Based Predictive Control for Autonomous Wheel‐Legged Robot System

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Mobile wheel‐legged robots exhibiting mobility, stability and reliability have garnered heightened research attention in demanding real‐world scenarios, especially in material transport, emergency response and space exploration. The kinematics model merely delineates the geometric relationship of the controlled objective, disregarding force ...

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

Boreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

A Fast Self-Calibration Method for Dual-Axis Rotational Inertial Navigation Systems Based on Invariant Errors

Sensors
In order to ensure that dual-axis rotational inertial navigation systems (RINSs) maintain a high level of accuracy over the long term, there is a demand for periodic calibration during their service life.

Technologies for equine welfare and performance monitoring under field conditions – Where do we stand?

Equine Veterinary Journal, EarlyView.
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Sensor-Based Balance Training with Exergaming Feedback in Subjects with Chronic Stroke: A Pilot Randomized Controlled Trial

Brain Sciences
Background: As one of the leading causes of disability in the world, stroke can determine a reduction of balance performance with a negative impact on daily activity and social life. In this study, we aimed to evaluate the effects of sensor-based balance

Parameterization of Biomechanical Variables through Inertial Measurement Units (IMUs) in Occasional Healthy Runners

Sensors
Running is one of the most popular sports practiced today and biomechanical variables are fundamental to understanding it. The main objectives of this study are to describe kinetic, kinematic, and spatiotemporal variables measured using four inertial measurement units (IMUs) in runners during treadmill running, investigate the relationships between ...

Reliability, agreement and variability of a markerless computer vision algorithm for equine gait analysis under field conditions

Equine Veterinary Journal, EarlyView.
Abstract Background Computer vision‐based algorithms offer accessible alternatives for equine gait analysis but require thorough assessment under diverse conditions. Objectives To evaluate a proprietary vision‐based algorithm's reliability in measuring vertical displacement signals (VDS) at the eye, withers and croup, alongside groundline estimation ...

Multi-IMU: Multiple Inertial Measurement Unit Systems in Mixed Reality

, 2021
Mixed Reality (MR) is an immersive technology that allows interaction in real-time with real and virtual objects. One of the major technologies of MR is tracking, i.e., determining the pose of an object in a chosen coordinate system. One of the tracking technologies is realized through Inertial Measurement Units (IMUs). This thesis contributes detailed
