Development of 5-DOF Piezoelectric Actuator for Planar—Angular Positioning
Applied Sciences, 2022 A novel five degrees of freedom (5-DOF) piezoelectric actuator is proposed and analyzed in this paper. The actuator can provide unlimited self-motion in the plane and angular positioning of the spherical payload. The actuator is composed of a cylindrical

Correction of positioning and angular errors for ball screw feed unit
Nihon Kikai Gakkai ronbunshu, 2014 In the present study, we developed a new feed correction mechanism which corrected not only a positioning error (i.e., feed deviation) but also an angular error (i.e., yaw of a table).

Accuracy of guide wire placement for femoral neck stabilization using 3D printed drill guides
3D Printing in Medicine, 2022 Background The goal of stabilization of the femoral neck is to limit morbidity and mortality from fracture. Of three potential methods of fixation, (three percutaneous screws, the Synthes Femoral Neck System, and a dynamic hip screw), each requires guide

Uncertainty principle for angular position and angular momentum
New Journal of Physics, 2004 The uncertainty principle places fundamental limits on the accuracy with which we are able to measure the values of different physical quantities (Heisenberg 1949 The Physical Principles of the Quantum Theory (New York: Dover); Robertson 1929 Phys. Rev. 34 127).
