Formulas for Derivatives of Solutions of the $$ \bar \partial $$ -Equation in the Ball
2006Letf ∫(z)=\( \sum\nolimits_{k = 1}^n {f_k (z)d\bar z_k } \) be a closed (0, 1) form in the unit ball B∈ℂ n , and let ua be the solution of the equation \( \bar \partial \)u=∫, which has the minimal norm in the weighted space L2[(1-|z|2)adv]. Some explicit integral formulas for the derivatives of ua are obtained.

A Study on the Ball-Bar Artifact for the Volumetric Error Calibration of Machine Tools
Transactions of the Korean Society of Mechanical Engineers A, 2004For volumetric error measurement and calibration for machine tools, manufacturing machine or coordinate measuring machine (CMM), are studied using a Ball-bar artifact. A design of the Ball-bar is suggested manufactured by Invar, which is a low thermal expansion material, and precision steel balls. The uncertainty for the artifact method is discussed. A
