Error-resilient Floquet geometric quantum computation [PDF]
Physical Review Research, 2021 We propose a geometric quantum computation (GQC) scheme, called Floquet GQC (FGQC), where error-resilient geometric gates based on periodically driven two-level systems can be constructed via a non-Abelian geometric phase proposed in a recent study [V ...

An Alignment Method for a TCP Position of Five-Axis Machine Tools for ISO 10791-6 [PDF]
한국정밀공학회지, 2021 ISO 10791-6 specifies test conditions, BK1 and BK2, including circularly interpolated motions by simultaneous control of two linear axes and a rotary/tilting axis, for five-axis machine tools with a tilting-rotary table.

The geometric error for homographies [PDF]
Computer Vision and Image Understanding, 2005 We address the problem of finding optimal point correspondences between images related by a homography: given a homography and a pair of matching points, determine a pair of points that are exactly consistent with the homography and that minimize the geometric distance to the given points.

Geometric View of Measurement Errors [PDF]
Communications in Statistics - Simulation and Computation, 2011 The slope of the best fit line from minimizing the sum of the squared oblique errors is the root of a polynomial of degree four. This geometric view of measurement errors is used to give insight into the performance of various slope estimators for the measurement error model including an adjusted fourth moment estimator introduced by Gillard and Iles ...

Development of the Heterodyne Laser Encoder System for the X–Y Positioning Stage
Sensors, 2021 This investigation develops a laser encoder system based on a heterodyne laser interferometer. For eliminating geometric errors, the optical structure of the proposed encoder system was carried out with the internal zero-point method.

Geometric Error Analysis of a 2UPR-RPU Over-Constrained Parallel Manipulator
Machines, 2022 For a 2UPR-RPU over-constrained parallel manipulator, some geometric errors result in internal forces and deformations, which limit the improvement of the pose accuracy of the moving platform and shorten the service life of the manipulator.

Error Correction and Detection, a Geometric Approach [PDF]
The Computer Journal, 1984 Summary: This paper is basically a tutorial on error detection and correction. The presentation though is via a new approach. This approach has an inherent characteristic leading to parallel hardware implementation and is thus better suited for computer and parallel processing applications.
