Source-position transformation -- an approximate invariance in strong gravitational lensing [PDF]
The main obstacle for gravitational lensing to determine accurate masses of deflectors, or to determine precise estimates for the Hubble constant, is the degeneracy of lensing observables with respect to the mass-sheet transformation (MST).

Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]
The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.

Introducing engineering undergraduates to CNC machine tool error compensation
For manually operated machine tools, the accuracy of the machine tool structure limits the accuracy of the parts produced. Such is not necessarily the case with computer numerically controlled (CNC) machine tools.
