Design Analysis of a 3-DOF Cable-driven Variable-stiffness Joint Module

, 2015
Variable-stiffness manipulators can produce intrinsically-safe motions, which are essential for next generation service robots. In this paper, the design analysis of a 3-DOF cable-driven joint module with variable stiffness is proposed.

GAD65 Antibody ELISA With Extended Reportable Range: Validation and Guidance for Neurological Practice

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To (1) validate GAD65‐ELISA detection and quantification for type 1 diabetes mellitus and autoimmune neurological diagnoses, (2) correlate ELISA results (reference range < 5 IU/mL) with established radioimmunoprecipitation assay (RIA; ≤ 0.02 nmol/L), and (3) define ELISA clinical utility and pitfalls.

Feedback linearization and simultaneous stiffness-position control of robots with antagonistic actuated joints.

, 2007
In this paper, the dynamic model of a robot with antagonistic actuated joints is presented, and the problem of full linearization via static state feedback is analyzed. The use of transmission elements with nonlinear relation between the displacement and

Elastic Curves With Variable Bending Stiffness

Studies in Applied Mathematics
ABSTRACTWe study stationary points of the bending energy of curves subject to constraints on the arc length and the curve's holonomy while simultaneously allowing for a variable bending stiffness along the arc length of the curve. Physically, this can be understood as a model for an elastic wire with isotropic cross section of varying thickness.
