Study of material removal behavior on R-plane of sapphire during ultra-precision machining based on modified slip-fracture model

引用

Nanotechnology and Precision Engineering 2020年第3期3卷 141-155页

作者： Suk Bum Kwon Aditya Nagaraj hae-Sung yoon Sangkee Min Department of Mechanical Engineering University of Wisconsin-Madison1513 University AvenueMadisonWI 53706United States of America School of Aerospace and Mechanical Engineering Korea Aerospace University76 Hanggongdaehak-roDeogyang-guGoyang-siGyeonggi-do 10540Republic of Korea

In this paper, the modified slip/fracture activation model has been used in order to understand the mechanism of ductile-brittle transition on the R-plane of sapphire during ultra-precision machining by reflecting direction of resultant force. Anisotropic characteristics of crack morphology and ductility of machining depending on cutting direction were explained in detail with modified fracture cleavage and plastic deformation parameters. Through the analysis, it was concluded that crack morphologies were mainly determined by the interaction of multiple fracture systems activated while, critical depth of cut was determined by the dominant plastic deformation parameter. In addition to this, by using proportionality relationship between magnitude of resultant force and depth of cut in the ductile region, an empirical model for critical depth of cut was developed.

A THREE-PARAMETER FAULT-DETECTION SOFTWARE RELIABILITY MODEL WITH THE UNCERTAINTY OF OPERATING ENVIRONMENTS

引用

Journal of Systems Science and Systems Engineering 2017年第1期26卷 121-132页

作者： Kwang yoon Song In Hong chang Hoang Pham Department of Computer Science and Statistics Chosun University Gwangju 62022 Korea Department of Industrial and Systems Engineering Rutgers University NJ 08855-8018 USA

As requirements for system quality have increased, the need for high system reliability is also increasing. Soflnvare systems are extremely important, in terms of enhanced reliability and stability, for providing high quality services to customers. However, because of the complexity of software systems, soft-ware development can be time-consuming and expensive. Many statistical models have been developed in the past years to estimate soflnvare reliability. In this paper, we propose a new three-parameter fault-detection software reliability model with the uncertainty of operating environments. The explicit mean value function solution for the proposed model is presented. Examples are presented to illustrate the goodness-of-fit of the proposed model and several existing non-homogeneous Poisson process （NHPP） models based on three sets of failure data collected from software applications. The results show that the proposed model fits significantly better than other existing NHPP models based on three criteria such as mean squared error （MSE）, predictive ratio risk （PRR）, and predictive power （PP）.

Purification of Astaxanthin from Laminaria japonica by Ionic Liquid-based Monolithic Cartridge

引用

Chemical Research in Chinese Universities 2012年第3期28卷 406-409页

作者： yoon chang-hwan ROW Kyung-ho Department of Chemical Engineering Inha UniversityIncheon 402-751Korea

An effective and accurate method was developed for the extraction of astaxanthin from Laminariajapo- nica with subsequent separation by ionic liquid-based monolithic cartridge. The optimized extraction conditions in- cluding extraction solvent（ethanol）, extraction time（90 min） and ultrasonic power（75 W） were obtained by systema- tical investigation. Chromatographic analysis was performed on a C18 column with ultraviolet（UV） detection at 476 nm, and a solution consisting of methanol/acetonitrile/H2O/dichloromethane（83：6：6：5, volume ratio） was used as the mobile phase at a flow rate of 0.7 mL/min. After ionic liquid-based monolithic solid phase extraction, 17.82 μg/g as- taxanthin was obtained from Laminaria japonica. This ionic liquid-based monolithic cartridge exhibits high affinity and selectivity for astaxanthin, and it can be potentially used as the stationary phase of high performance liquid chromatography（HPLC）.
