Experimental imperfections induce phase and population errors in quantum systems. We present a method to compensate unitary affecting also the of qubit states. This is achieved through interaction target with an additional control qubit. show that our approach works well for single-photon two-photon excitation schemes. In first case, we study two reduced models (i) two-level system which corres...

This paper presents an algorithm to compensate the systematic error of lasers line scanned data based on measurement model system. The iterative process is used determine geometrical features accurately, solely making use optical device. task-specific reduced by algorithm. validation consists evaluation multiple compensated measurements calibrated ring gauges with different diameters and simila...

The method of end-effector pose accuracy improvement using joint error mutual compensation for robotic manipulators with rotation joints was presented. The computer simulation and experiments of the developed method showed that it was possible to perform the technological operations with a higher accuracy in the special areas of the robot working space using the developed approach. The method p...

One of the important trends in precision machining is the development of real-time error compensation technique. This paper presents the research work under the authors and their team in this area. The technique has been applied to more than 10 different kinds of machines including: turning centers and machining centers; small, medium and large machines; new products and retrofitted machines. T...

A volumetric error compensation method for a machining center that has multiple cutting tools operating simultaneously has been developed. Due to axis sharing, the geometric errors of multi-spindle, concurrent cutting processes are characterized by a significant coupling of error components in each cutting tool. As a result, it is not possible to achieve exact volumetric error compensation for ...

A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular ra...
