Automatic Registration of Footsteps in Contact Regions for Reactive Agility Training in Sports

open access: yesSensors, 2020
In collective sports, reactive agility training methodologies allow to evaluate and improve the player performance, being able to consider a mixture of technical, tactical, physical, and psychological abilities, similarly to real game-play situations. In

On the influence of detection tests on deterministic parameters estimation [PDF]

open access: yes, 2006
In non-linear estimation problems three distinct regions of operation can be observed. In the asymptotic region, the Mean Square Error (MSE) of Maximum Likelihood Estimators (MLE) is small and, in many cases,close to the Cramer-Rao bound (CRB).

Automatic Detection of Sfe: A Step Forward

open access: yesAtmosphere, 2022
Solar flare effects (Sfe) are magnetic variations caused by solar flare events. They only show up in the illuminated hemisphere. Their detection is a difficult task because they do not have a definite pattern and, additionally, they must be separated ...

Research on Six-Axis Sensor-Based Step-Counting Algorithm for Grazing Sheep

open access: yesSensors, 2023
Step counting is an effective method to assess the activity level of grazing sheep. However, existing step-counting algorithms have limited adaptability to sheep walking patterns and fail to eliminate false step counts caused by abnormal behaviors ...
