This paper utilizes the quantitative feedback theory (QFT) to design a robust controller for adaptive cutting feedrate control. The proposed algorithm could dynamically change the feedrate according to the spindle current which is highly related to the measured cutting force. The QFT controller could provide the constant cutting force even under different cutting condition. Hence, the machining efficiency...
This study reports a magnetic-bead based microfluidic system to capture cholangiocarcinoma cells by using structurally well-defined heparan sulfate (HS) octasaccharides. Ten synthetic HS octasaccharides (from SCH-43 to SCH-52) were coated on magnetic beads for this study, respectively. An integrated microfluidic system equipped with micromixers, normally-closed valves, and microchambers was developed...
High-field MRI has the challenge of inhomogeneous B1+ and consequently an inhomogeneous flip angle distribution. This causes spatially dependent contrast and makes clinical diagnosis difficult. Under the small flip angle approximation and using nonlinear spatial encoding magnetic fields (SEMs), we propose a method to remap the B1+ map into a lower dimension coordinate system. Combining with RF shimming...
This paper is intended to demonstrate that graphene oxide (GO) on Au films based surface plasmon resonance technique for protein kinetic analysis. The results show that the detection limits of GO sheets were dramatically improved.
A mixture experiment treats a product that is formed of several ingredients together (e.g. gasoline, detergents, and cookies). A mixture experiment is a special type of parameter in which the factors are the ingredients or components of a mixture. Although there have many researchers proposed various methods to improve the design of the mixture experiments, those cannot provide effective analysis...
Driving safely has received increasing attention of the publics due to the growing number of traffic accidents that the driver's driving style is highly correlated to many accidents. The purpose of this study is to investigate the relationship between driver's driving style and driver's ERP response. In our research, a virtual reality (VR) driving environment is developed to provide stimuli to subjects...
