Precise Relative Positioning for Tandem Drifting Cars
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021Drifting provides insights into how autonomous cars handle excursions past stable limits. So far, autonomous drifting has been demonstrated for a single car where GPS carrier phase measurements provide cm-level accuracy in absolute position via base station corrections. We aim to extend the single car drifting to tandem drifting. However, in autonomous

Precision Experimental Verification of Special Relativity
Physical Review Letters, 1978We compare the results of precision electron $g$-factor experiments at low energy and at 110 keV. The agreement between these measurements constitutes the most precise laboratory confirmation to date of the predictions of special relativity. Relativistic electromagnetic theory and Thomas precession are verified in this test.

Technique for precision beveling of relatively large micropipettes
Journal of Neuroscience Methods, 1979A technique is described for embedding various sizes of diamond dust in a film of Varathane laid upon an optically flat glass surface. This forms a precise and very durable abrasive surface. When such abrasive surfaces are used with previously described equipment, micropipettes may be beveled rapidly and reliably to tip diameters extending from 0.5 ...

Significance of precision tests of special relativity
Physics Letters A, 1993Abstract Recent experiments using two-photon absorption and phase comparison of masers can set bounds on Lorentz-violating preferred-frame alternatives to special relativity, but cannot give empirical knowledge concerning the one-way speed of light, since the latter depends on the synchronisation convention.

Precise relative cross sections for np scattering
Nuclear Physics A, 1994Abstract We present data on the differential cross section for neutron-proton scattering for an incident neutron energy of 67 MeV. These data allow a precise determination of the 1P1 phase which, in phase-shift analyses, is strongly correlated with the S-D amplitude which we are measuring via different observables.
