For it was shown above that corresponding to two infinitely near space-time points there is a number ds which can be obtained by measurement with rigid measuring-rods and clocks (in the case of time-like elements, indeed, with a clock alone).
Rigid hull measurements are compared with the compliant hull configuration for a mini-TLP model.
Standing height and body weight were measured with a rigid vertical height measurement and a standard medical balance scale, with subjects not wearing shoes and in light clothes.
So, we designed the monocular vision rigid body posture measurement system, determined a method to unify the each feature point measure coordinates in each coordinate system under the experimental conditions.
Then, we analyzed the theoretical sources of error from rigid body posture measurement system simulation experiments.
Einstein argued that the question concerning the nature of spacetime geometry becomes an empirical question only on certain pro tem stipulations regarding the "practically rigid body" of measurement (pro tem in view of the inadmissibility in relativity theory of the concept "actually rigid body").
A nonlinear observer (i.e. a "filter") is proposed for estimating the attitude of a flying rigid body, using measurements from low-cost inertial and magnetic sensors.
This review describes a buffeting prediction technique based on rigid model pressure measurements that is commonly used in North America, and also the buffet excitation parameter technique favored by many researchers in the UK.
A "calibration-index" derived solely and continuously from pulse-contour-analysis might be a useful tool to improve the yield of relevant TPTD-measurements and to reduce "routine -measurements afteroutine -measurements
It enabled spatial reconstruction of the wall movement, characterization of its rigid body motion and measurement of both displacements and strain fields in in-plane and out-of-plane load applications.
