Parent and adolescent (M = 15.7 years) beliefs regarding parents’ right to know (RTK) about adolescents’ activities were examined in 174 middle-class U.S. families. Mean differences and associations with latent changes in teens’ concealment were assessed. RTK was greatest about risky prudential activities, least for personal activities for parents and romantic activities for teens, and higher f...

BACKGROUND AND PURPOSE There are no published studies on the parameterisation and reliability of the single-leg stance (SLS) test with inertial sensors in stroke patients. Purpose: to analyse the reliability (intra-observer/inter-observer) and sensitivity of inertial sensors used for the SLS test in stroke patients. Secondary objective: to compare the records of the two inertial sensors (trunk ...

In this work an efficient dynamics algorithm is developed which is applicable to a wide range of multibody systems, including underactuated systems, branched or treetopology systems, robots, and walking machines. The dynamics algorithm is differentiated with respect to the input parameters in order to form sensitivity equations. The algorithm makes use of techniques and notation from the theory...

This paper presents a Divide and Conquer strategy to estimate the kinematic parameters of parallel symmetrical mechanisms. The Divide and Conquer kinematic identification is designed and performed independently for each leg of the mechanism. The estimation of the kinematic parameters is performed using the inverse calibration method. The identification poses are selected optimizing the observab...

A novel, e/cient and mathematically rigorous continuum based sensitivity method is introduced that can be used to accurately evaluate the gradients of the objective function and constraints in the optimization-based design of multi-stage deformation processes. Weak sensitivity equilibrium equations are derived for the large deformation of the workpiece in each forming operation. This sensitivit...
