A brief review of the existing methods for solving inverse kinematics problem multilink mechanical systems is carried out. geometric model an industrial manipulator KUKA family with six degrees freedom developed. special method separately a spherical wrist design applied to demonstrate this approach efficiency. An approximate numerical solution implemented in software. The effectiveness softwar...

Purpose To evaluate the degree of conversion (DoC) self-adhesive resin luting cements when irradiated through different fiber post lengths. Methods A total 60 teeth were sectioned to achieve lengths 4 mm, 7 and 10 while posts trimmed give 3 6 9 mm Post space was created accommodate 1 cement apically. Two (Multilink Speed RelyX U200) used. four cycles 20 s irradiation done with an attenuated ref...

Multilink robot arms are geometrically similar to chain molecules. We investigate the performance of molecular simulation methods, combined with stochastic methods for optimization, when applied to problems of robotics. An eecient and exible algorithm for solving the inverse kinematic problem for redundant robots in the presence of obstacles (and other constraints) is suggested. This \Constrain...

abstract   background: traumatic or congenital events can result in injury and functional deficiency in the hand and we need to reconstruct the fingers at times. studies are available in the pediatric and adult age groups to assess the length of the thumb. but to the best our knowledge no measurement of the relative clinical length of all fingers has been reported in the literature. we performe...

bilateral finger and palm prints of 500 males and 500 females of the caucasian origin in south iran have been collected and analyzed for both qualitative and quantitative dermatoglyhic features. results show that most of the qualitative features on bilateral and bisexual differences are not significant. however, quantitative features frequently showed significant differences both bilaterally an...

This article presents our current work on studying energy efficient locomotion on crawling snake-like robots. The aim of this work is to use existing biological inspired methods to demonstrate lateral undulation planar gaits for efficiently controlling high-speed motion as a function of the terrain surface. A multilink non-wheeled snake-like robot is being developed for experimentation and anal...

The goal of this work is to quantitatively assess the relationship between the reported restenosis rates and stent induced arterial stress or strain parameters through finite element method. The impact of three stent designs (Palmaz–Schatz stent, Express stent, and Multilink Vision stent) on the arterial stress distributions were characterized. The influences of initial stent deployment locatio...
