objectives: investigating the effect of endurance training program onthe gait pattern of non-active elderly people. methods & materials: this study has been done by a semi-experience method with 23 old men and women by the average and standard deviation of 70/50±6/9 years old (n=14 people of exercise group, n=9 people of control group). the exercise group took part in this program for eight wee...

considering the nonlinear hyperelastic or viscoelastic nature of soft tissues has an important effect on modeling results. in medicalapplications, accounting nonlinearity begets an ill posed problem, due to absence of external force. myocardium can be consideredas a hyperelastic material, and variational approaches are proposed to estimate stiffness matrix, which take into account the linearand...

When human subjects are presented with visual displays consisting of random dots moving sideways at different velocities, they perceive transparent surfaces, moving in the same direction but located at different distances from themselves. They perceive depth from motion parallax, without any additional cues to depth, such as relative size, occlusion or binocular disparity. Simultaneously, large...

Extremely large optical telescopes are being designed with primary mirrors composed of hundreds of segments. The "out-of-plane" piston, tip, and tilt degrees of freedom of each segment are actively controlled using feedback from relative height measurements between neighboring segments. The "in-plane" segment translations and clocking (rotation) are not actively controlled; however, in-plane mo...

BACKGROUND Immobilization after tendon transfers has been the conventional postoperative management. Several recent studies suggest early mobilization does not increase tendon pullout. QUESTIONS/PURPOSES To confirm those studies we determined whether when compared with immobilization early active mobilization after a tendon transfer for foot-drop correction would (1) have a similar low rate o...

This paper proposes a method for recognizing human behaviors based on a combination of “overall motion analysis using Hidden Markov Model (HMM)” and “detailed feature analysis in a specific area by using an active (pan-tilt-zoom, PTZ) camera”. The PTZ parameters are controlled depending on the intermediate result of analyzing the target’s motions based on HMM. As a result, our system can distin...

The relative motion splint was initially developed to facilitate postoperative rehabilitation after repair of extensor tendon injuries at the dorsum of the hand and forearm. It has subsequently been used for rehabilitation of sagittal band injuries and after repair of closed attrition extensor tendon ruptures in rheumatoid arthritis. This is much less awkward than other braces and can readily b...

In the early steps of visual information processing motion is one of the most important queues for the development of spatial representations. Obstacle detection and egomotion estimation are only two examples of the powerfulness of visual motion detection systems. The underlying process of information extraction has to be active due to the observer’s capabilities of egomotion. This means that t...
