Sonar EKF-SLAM and mapping in an structured underwater environment [PDF]
, 2020 En av de store utfordringene for autonome undervans farkoster idag er navigering i lengre perioder uten og g˚a opp til overflaten for og korrige posisjons estimatione ved hjelp av GNSS.

Preventing overfilling of blood bags to reduce clot formation and improve donor safety
Vox Sanguinis, EarlyView.Abstract Background and Objectives Overfilling of blood bags is common in low‐resource settings, causing clot formation, donor and recipient risks and blood wastage. This study assessed overfilling prevalence and evaluated a low‐cost intervention to mitigate it.

An EKF-Based Fixed-Point Iterative Filter for Nonlinear Systems [PDF]
, 2019 In this paper, a fixed-point iterative filter developed from the classical extended Kalman filter (EKF) was proposed for general nonlinear systems. As a nonlinear filter developed from EKF, the state estimate was obtained by applying the Kalman filter to

Jumping on the moon as a potential exercise countermeasure
Experimental Physiology, EarlyView.Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Robustness Evaluation of Extended and Unscented Kalman Filter for Battery State of Charge Estimation
IEEE Access, 2018 In this paper, the robustness of model-based state observers including extended Kalman filter (EKF) and unscented Kalman filter (UKF) for state of charge (SOC) estimation of a lithium-ion battery against unknown initial SOC, current noise, and ...

Experimental Physiology, EarlyView.Abstract We investigated the effect of internal and external cooling on high‐intensity intermittent cycling performance and cognitive function in the heat. Twenty‐nine males completed a control trial (CON) and a cooling trial (ice slurry and ice collar; COOL) in the heat (33°C, 50% relative humidity) involving a 40 min intermittent cycling protocol ...

CROSS-COVARIANCE ESTIMATION FOR EKF-BASED INERTIAL AIDED MONOCULAR SLAM [PDF]
, 2013 Repeated observation of several characteristically textured surface elements allows the reconstruction of the camera trajectory and a sparse point cloud which is often referred to as "map".

Experimental Physiology, EarlyView.Abstract A mixed‐method heat acclimation (HA) protocol may optimise performance by supporting the training taper while promoting thermal adaptation; however, the impact on cardiovascular and fluid‐regulatory adjustments to protect health is unknown. Therefore, we examined the effects of a mixed‐method heat protocol on physiological responses, including

Experimental Physiology, EarlyView.Abstract Exercise in hot climates increases the risk of gastrointestinal (GI) disruption and respiratory illness. We investigated the effects of a 42 day prebiotic intervention on markers of intestinal epithelial injury, GI discomfort and immunity following football specific exercise in the heat and daily upper respiratory illness.

An Improved EKF-SLAM for Mars Surface Exploration [PDF]
, 2019 In the traditional EKF-SLAM algorithm, the computational complexity and uncertainty will grow up rapidly with the increase of the feature points and the enlargement of the map coverage.
