Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...

dear editor we read the article by bagheri et al with great interest (1). we found the study interesting and comprehensive as four groups of patients, including operative and nonoperative in either pure dislocation or fracture dislocation, were compared in terms of mayo wrist score, grip strength, range of motion and radiographic parameters. it seems that the results were comparable to studies ...

Target motion-induced uncertainty in particle therapy is more complicated than that in X-ray therapy, requiring more accurate motion management. Therefore, a hybrid motion-tracking system that can track internal tumor motion and as well as an external surrogate of tumor motion was developed. Recently, many correlation tests between internal and external markers in X-ray therapy have been develo...

In this paper, we present a car tracking system which provides quantitative and qualitative motion estimates of the tracked car simultaneously from a moving observer. First, we construct three motion models (constant velocity, constant acceleration, and turning) to describe the qualitative motion of a moving car. Then the models are incorporated into the Extended Kalman Filters to perform quant...

normal range of joint motion is an important factor in joint examination in clinical practice which is related to factors such as age, sex and geographic region. there is no data in the literature on the range of joint motions in healthy iranian adults. we studied joint motions in 100 healthy volunteer subjects, 49 men and 51 women, from 19 and 58 years of age. the joint mobility was examined i...

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...

piezoelectric microcantilevers (mcs) are a new generation of microbeams used in atomic force microscopes (afms). due to their miniaturization of afms as well as their increased imaging precision and speed, these mcs are more popular than their classical counterparts. given the widespread application of these beams in nanoparticle topography, analysis of their vibrating motion has attracted much...

introduction: motion of the patient during myocardial perfusion spect could potentially results in false perfusion defects. the effect of different reconstruction methods on these artifacts is not studied. clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. this study...

We describe the Harmonic Motion Description Protocol (HMDP), that can serve as a part in tools for rapid prototyping of behaviors in a hybrid simulation real robot environment. In particular, we are focusing on the RoboCup 3D Soccer Simulation League server that is currently evolving rapidly, and becomes a more and more useful open source, general purpose simulation environment for physical Mul...
