In this research we design a passive controller for an above knee prosthesis. The controller is a linear spring and damper for swing phase motion, parameters of which determined via optimization of adjustment of the prosthesis shank motion with a desired shank angle trajectory comes from experimental data. In this way, we exerted a certain thigh motion, hip movement included, into the system as...

understanding the essence of movement and knowing how it exists in the physical world, is considered one of the most important philosophical issues in which wise men were occupied with, whether in the greek era or the islamic one. and if the presence of change was of much certainty as well as movement in the physical world, then, the most important issue is the study of how it is present outwar...

conclusions the odscp has many advantages over the other type of plates. it can help the surgeon to operate with a relaxed mind and it is advisable for high tibial medial open wedge osteotomies. results the mean follow-up time was 9.33 ± 1.87 month. the average age was 45.13 ± 7.25 years. three patients were male and 13 patients were female. the lysholm score showed a significant difference bef...

there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...

objectives: this study was designed to determine the effects of volar-dorsal wrist/hand immobilization splint on upper extremity motor components and function of stroke patients. methods: fourteen patients were participated in this study. the patients were selected based on the inclusion and exclusion criteria, and were given the splint after a primary evaluation. they were re-evaluated after o...

recently a method has been developed to decouple the equations of motion for multi-rigid body systems. in this paper, the method is first studied, then the equations of motion for a planar two degree-of-freedom robot with flexible joints are carried out using lagaranges equations and kanes equation with congruency transformations. finally, the results obtained from both methods are throroughly ...

background:  the glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. the most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...

department of islamic philosophy and wisdom, zanjan university bringing up the ancients’ views and asking about their ultimate condition in mullā ṣadrā’s thinking and that of his disciples has had a significant impact on the formation and development of the motion theory. mentioning the names and bringing up the views of the ancient greek philosophers, as evidences for truthfulness in the disco...
