Turkey arthritis reovirus (TARV) causes lameness and tenosynovitis in commercial turkeys and is often associated with gastrocnemius tendon rupture by the marketing age. This study was undertaken to characterize the biomechanical properties of tendons from reovirus-infected turkeys. One-week-old turkey poults were orally inoculated with O'Neil strain of TARV and observed for up to 16 weeks of ag...

This paper investigated the factors that influence Hecht vault performance and assessed the level of model complexity required to give an adequate representation of vaulting. A five-segment planar simulation model with a visco-elastic shoulder joint and a torque generator at the shoulder joint was used to simulate the contact phase in vaulting. The model was customized to an elite gymnast by de...

Cable Driven Parallel Robots (CDPRs) are parallel robots, in which the limbs replaced by cables that guided pulleys. In many papers, pulleys considered as fixed points of passage and cable elasticity is neglected. Those approximations simplify robot modelling, but lead to some Moving-Platform (MP) pose errors. This paper deals with modelling suspended three degree-of-freedom CDPRs considering g...

This paper describes the dynamics identification of the foot viscoelasticity of humanoid robots. It is important to know correctly dynamics parameters of link and joint which constitute a robot for its simulation and model based control. When walking, humanoids receive impulsive force at each step. Some humanoids have shock absorber and rubber bush in their soles. In simulation, accuracy of ine...

In this study, a soft sensor-based three-dimensional (3-D) finger motion measurement system is proposed. The sensors, made of the soft material Ecoflex, comprise embedded microchannels filled with a conductive liquid metal (EGaln). The superior elasticity, light weight, and sensitivity of soft sensors allows them to be embedded in environments in which conventional sensors cannot. Complicated f...

This paper provides a solution to the stability puzzle (Evans and McGough [11]): indeterminacy almost always implies expectational unstability in reduced-form real business cycle (RBC) models. After relaxing the restrictions on the magnitude of capital externalities with CobbDouglas technology, we nd regions for joint indeterminacy and E-stability in the following cases that i) the felicity fun...

Recent research in robotics focuses the attention on the control of compliant actuators to improve safety and to make the interaction with humans more natural. Lightweight construction, real elasticity directly integrated into the joint and control of joint compliance seem to play the most important role for improving safety in human-machine interaction. Humans are intrinsically elastic and the...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...

Modern Lightweight robots are constructed to be collaborative, which often results in a low structural stiffness compared conventional rigid robots. Therefore, the controller must able handle dynamic oscillatory effect mainly due intrinsic joint elasticity. Singular perturbation theory makes it possible decompose flexible dynamics into fast and slow subsystems. This model separation provides ad...
