Analysis for Feasibility of the Method for Bars Driving the Ball Tensegrity Robot
Journal of Mechanisms and Robotics, 2017In tensegrity robots, the ball tensegrity robot attracts the most attention. The method of driving the ball tensegrity robot is analyzed here. At first, the ball tensegrity structure is described, and its mathematical model is setup. Through analysis, the method for driving bars to make the robot deform and roll is selected.

Ball Impact Response of Unstrengthened and Chemically Strengthened Glass Bars
Journal of the American Ceramic Society, 2013Ball impact experiments were conducted at impact velocities of 52–345 m/s on unstrengthened and chemically strengthened lithium aluminosilicate glass bars to assess the damage propagation characteristics. The damage was captured by high‐speed imaging at frame rates up to 500 000 frames per second (fps).

Estimates for the $$\bar \partial $$ -equation and zeros of holomorphic functions on the Lie-ball
Archiv der Mathematik, 1992The \({\bar \partial}\)-equation for (0,1)-forms on the Lie-ball is solved with some weighted \(L^ 1\)-estimates. The author uses the integral formula of Berndtsson and Andersson and the weighted \(L^ 2\)-estimate of Ohsawa. A sufficient condition for an analytic set to be the zero set of a holomorphic function of finite order on the Lie-ball is got ...

Journal of Oral Implantology, 2013
In an implant-supported overdenture, the optimal stress distribution on the implants and least denture displacement is desirable. This study compares the load transfer characteristics to the implant and the movement of overdenture among 3 different types of attachments (ball-ring, bar-clip, and magnetic).

Improvement in the surface quality of ball bearing steel rounds at Bar Mill
Scandinavian Journal of Metallurgy, 2002The rejection of ball bearing steel rounds had increased at Bar Mill due to surface defects following an increase in the demand for a better surface quality. The genesis of surface defects in ball bearing steel rounds is attributed to steel‐making and rolling processes.

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
