✦ Synopsis

In biomechanics studies, inverse dynamics analysis (IDA) is corrupted by numerous sources of error that reduce its usefulness. In this work, a systematic procedure to account for these sources of error is presented and implemented in a simplified 2D biomechanical model. A sensitivity analysis is performed to determine the relative importance of each type of error in the IDA. The most important errors are the raw displacement differentiation and the kinematic inconsistency induced by skin motion. The wobbling mass motion effect is appreciable only in jerky motions.

The mass estimate of the d \* (I J P = 03 + ) dibaryon is improved by a dynamical calculation in the quark delocalization, color screening model. The partial decay width of d \* into an NN D-wave state is also obtained. The mass obtained is slightly larger than that obtained in adiabatic calculation
