This paper presents a summary of the new semi-analytical integration method presented in [10] for von Mises elastoplasticity model with combined linear isotropic-kinematic hardening within a small deformation range. Solutions for the case of constant strain rate and constant stress rate assumptions are also presented. Furthemore, it is shown how the general solution reduces to the particular ca...

PURPOSE In this investigation, the authors determined the strength of association between tongue kinematic and speech acoustics changes in response to speaking rate and loudness manipulations. Performance changes in the kinematic and acoustic domains were measured using two aspects of speech production presumably affecting speech clarity: phonetic specification and variability. METHOD Tongue ...

We present a method called muscle synergy analysis, which can offer clinicians insight into both underlying neural strategies for movement and functional outcomes of muscle activity. Although neural dysfunction is central to many motor deficits, neural activity during movements is not directly measurable. Consequently, the majority of clinical tests focus on evaluating motor outputs at the beha...

How do we understand the intentions of other people? There has been a longstanding controversy over whether it is possible to understand others' intentions by simply observing their movements. Here, we show that indeed movement kinematics can form the basis for intention detection. By combining kinematics and psychophysical methods with classification and regression tree (CART) modeling, we fou...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

BACKGROUND AND PURPOSE Upper limb motor impairment poststroke is commonly evaluated using clinical outcome measures such as the Fugl-Meyer Assessment. However, most clinical measures provide little information about motor patterns and compensations (eg, trunk displacement) used for task performance. Such information is obtained using movement quality kinematic variables (joint ranges, trunk dis...

Simulating the movement of a snatch weightlifter by means of the dynamic formulation and optimizing this movement using Genetic Algorithm as a soft computing method is the main purpose of this study. The snatch weightlifter is modeled by an open kinematic chain. The problem is defined as the optimization of the movement of this model from the first position to the predefined second position whi...

BACKGROUND Postural correlates of vocal effort are rarely described in the literature, while they are extensively dealt with in speech therapy. OBJECTIVES This study aims at determining whether body movement is a side effect of vocal effort or an integral part of communication effort behavior. The answer to this question is mainly based on correlations between posture and phonation. METHOD ...
