Angles of arrival of first echoes (those directly reflected from the ionosphere) and second echoes (those twice reflected from the ionosphere with an intermediate reflection from the ground) were measured. It is easy to show that under specified conditions the off-vertical angle of arrival of the...
The measurement of the stiffness of a precision reducer is essential to estimating the reducer. Since the angular sensor’s measurement results include the angle measurement error caused by the instrument’s torsional deformation, it cannot be used as the actual torsional deformation of the reducer. ...
One way to measure the angular coherence function is by measuring the interference visibility in a Mach–Zehnder interferometer as a function of the Dove-prism rotation angle31, 32. Although this method does not have any coupling-efficiency issue, it still requires a series of measurements for ...
Research on measuring method of power angle and D-Q axis reactance parameters of rare earth permanent magnet synchronous motor (REPM) is presented. Singlechip measuring instrument of power angle and measuring installation of voltage integration method have been developed. Based on the instrument, metho...
This theoretical element of the study shows how the angular uncertainty is affected by internal parameters, the actual values of which are estimated. Experiments are then carried out to determine the actual uncertainty in the azimuth angle. Results are presented that show that uncertainty decreases ...
The present study was undertaken to determine whether there is a constant difference between the angle of inclination and the Alsberg angle and to evaluate statistical relationships between the inclination angle, Alsberg angle and the angle between the anatomical and mechanical axes of the femur. Me...
The angle of traverse measurement equipment and in the angle of traversePROBLEM TO BE SOLVED: To provide a revolving angle measuring device capable of accurately measuring a revolving angle of a boom without requiring high cost.渡部 義明小林 雅夫...
Small-angle pp elastic scattering and the real-to-imaginary ratio of the forward amplitude between413 and 715 MeV c We have measured the pp forward elastic differential cross section between 413 and 715 MeV c. The real-to-imaginary ratio of the pp forward-scattering amplitude was determined, ...
Monitoring joystick operations in power wheelchairs (PWCs) is promising for investigating user-wheelchair interaction and providing quantitative measures to assess the user’s driving performance. In this paper, an add-on measurement system, Power Wheelc
