The second argument is

angular acceleration. Cycle time required in this work for pick and place operation was two seconds.

Generally, the velocity and

angular acceleration are obtained by differential of position and differential of the velocity, respectively.

Finally, the three dependent measures in this study consisted of mean wrist

angular acceleration in the flexion/extension, radial/ulnar, and supination/pronation planes of the wrist.

Moreover, (12) shows that [F.sub.c]([??]) is an evolved suspension damping force being a linear function of the half-car body pitch

angular acceleration Q and only supplements the yielded front and rear quarter-car suspension damper forces with the same magnitude but an inverse phase.

Measurement principles for the

angular accelerationAmong the methods described there are: a torsion balance where the gravitational torque is balanced by an electrostatic torque produced by an electrometer; a torsion-strip balance where the fibre is substituted by a strip; a dynamic method based on a rotating torsion pendulum with

angular acceleration feedback; a free fall method where the determination of G depends on changes in acceleration of the falling object, etc.

The estimation process consists of the following three steps: noise reduction, calculation of

angular acceleration, and inertia estimation.

Where: M -Torque [Nm], I--inertia [kg[m.sup.2]] and [epsilon]

angular acceleration [rad/[sec.sup.2]].

We termed the acceleration phase as the time lag between the moment when the

angular acceleration of the trunk rotation became maximal to ball release, and post ball release from ball release to the end (100ms after ball release).

Preliminary but more attentive reference to NASA data allows noticing that observed

angular acceleration of the probes too could significantly incorporate to values of "relativistic deceleration".

The

It is obvious from (23) that if the feedforward is to be applied, a value of reference

angular acceleration, [[epsilon].sub.ref], must be available.

The most important parameter is a maximal

angular acceleration that a human head can achieve.
