Multibody-Based Input and State Observers Using Adaptive Extended Kalman Filter
(MDPI, 2021-08)
[Abstract] The aim of this work is to explore the suitability of adaptive methods for state estimators based on multibody dynamics, which present severe non-linearities. The performance of a Kalman filter relies on the ...
Lower Back Injury Prevention and Sensitization of Hip Hinge with Neutral Spine Using Wearable Sensors during Lifting Exercises
(MDPI, 2021-08)
[Abstract] The popularization and industrialization of fitness over the past decade, with the rise of
big box gyms and group classes, has reduced the quality of the basic formation and assessment
of practitioners, which ...
Comparison of Several Muscle Modeling Alternatives for Computationally Intensive Algorithms in Human Motion Dynamics
(Springer, 2022-04-05)
[Abstract] Several approaches are currently employed to address the predictive simulation of human motion, having in common their high computational demand. Muscle modeling seems to be an essential ingredient to provide ...
Use of performance indicators in the analysis of running gait impacts
(2018)
[Summary]
Foot-ground impact is a critical event during the running cycle. In this work, three performance indicators were used to characterize foot-ground impact intensity: the effective preimpact kinetic energy, ...
Roll Angle Estimation of a Motorcycle through Inertial Measurements
(MDPI, 2021-10)
[Abstract] Currently, the interest in creating autonomous driving vehicles and progressively more sophisticated active safety systems is growing enormously, being a prevailing importance factor for the end user when choosing ...
Online Kinematic and Dynamic-State Estimation for Constrained Multibody Systems Based on IMUs
(Multidisciplinary Digital Publishing Institute, 2016)
[Abstract] This article addresses the problems of online estimations of kinematic and dynamic states of a mechanism from a sequence of noisy measurements. In particular, we focus on a planar four-bar linkage equipped with ...
The use of wearable inertial sensors and workplace-based exercises to reduce lateral epicondylitis in the workstation of a textile logistics center
(MDPI, 2023-05-27)
[Abstract]: People whose jobs involve repetitive motions of the wrist and forearm can suffer from lateral epicondylitis, which is a significant burden on both the individual and the employer due to treatment costs, reduced ...
Thermal Parameter and State Estimation for Digital Twins of E-Powertrain Components
(IEEEAccess, 2021-07)
[Abstract] The performance of powertrain components in electric vehicles is tightly intertwined with their thermal behavior. In practical applications, their temperature must be monitored and kept below certain thresholds ...
Load assessment and analysis of impacts in multibody systems
(2016-09)
[Abstract] The evaluation of contact forces during an impact requires the use of continuous force based methods. An accurate prediction of the impact force demands the identification of the contact parameters on a case-by-case ...
Assessment of Linearization Approaches for Multibodydynamics Formulations
(2017-07)
[Abstract] Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear Differential Algebraic Equations (DAEs). While this form of the equations ...
