Dynamic Modeling of the Electromyographic and Masticatory Force Relation Through Adaptive Neuro-Fuzzy Inference System Principal Dynamic Mode Analysis

Introduction: Researchers have employed surface electromyography (EMG) to study the human masticatory system and the relationship between the activity of masticatory muscles and the mechanical features of mastication. This relationship has several applications in food texture analysis, control of prosthetic limbs, rehabilitation, and teleoperated robots. Materials and Methods: In this paper, w...

Construction and validation of the 4-item dynamic gait index.

BACKGROUND AND PURPOSE People with balance disorders often have difficulty walking. The purpose of this study was to develop and test the psychometric properties of a short form of the Dynamic Gait Index (DGI) for the clinical measurement of walking function in people with balance and vestibular disorders. SUBJECTS A total of 123 subjects with such disorders (test subjects) and 103 control su...

Classifying dynamic textures via spatiotemporal fractal analysis

The large-scale images and videos are one kind of the main source of big data. Dynamic texture (DT) is essential for understanding the video sequences with spatio-temporal similarities. This paper presents a powerful tool called dynamic fractal analysis to DT description and classification, which integrates rich description of DT with strong robustness to environmental changes. The proposed dyn...

Actuator driving force analysis and modelling of TRR-XY PKM

The main aim of this work is to investigate the actuator driving force variations of a parallel kinematic machine (PKM) for different cutting paths. To meet this aim, a TRR-XY Ž ve-degrees-of-freedom (5DOF) PKM was selected and built for this research, and a dynamic analysis model of the PKM was developed. Here, ‘T’ stands for translational DOF and ‘R’ stands for rotational DOF of the platform....
