Interpolation of a spline developable surface between a curve and two rulings

Alicia CANTÓN,Leonardo FERNÁNDEZ-JAMBRINA

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 3,   Pages 173-190 doi: 10.1631/FITEE.14a0210

Abstract: In this paper we address the problem of interpolating a spline developable patch bounded by a given splinecurve and the first and the last rulings of the developable surface.We circumvent such difficulty by resorting to degree elevation of the developable surface.This is useful for solving not only this problem, but also other problems dealing with triangular developable

flexible accelerometer fabricated using micro-electro-mechanical system technology for bending structure surfaces Research Article

Chen LI, Mangu JIA, Yingping HONG, Yanan XUE, Jijun XIONG,lichen@nuc.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 5,   Pages 801-809 doi: 10.1631/FITEE.2100236

Abstract: We propose an inductor-capacitor (LC) wireless passive , which eliminates the difficulty in measuring the acceleration on the surface of a bending structure. The accelerometer is composed of a flexible polyimide (PI) substrate and a planar spiral inductance coil (thickness 300 nm), made using . It can be bent or folded at will, and can be attached firmly to the surface of objects with a bending structure. The principle of radio frequency wireless transmission is used to measure the acceleration signal by changing the distance between the accelerometer and the antenna. Compared with other accelerometers with a lead wire, the accelerometer can prevent the lead from falling off in the course of vibration, thereby prolonging its service life. Through establishment of an experimental platform, when the distance between the antenna and accelerometer was 5 mm, the characterization of the surface of bending structures demonstrated the sensing capabilities of the accelerometer at accelerations of 20‒100 m/s. The results indicate that the acceleration and peak-to-peak output voltage were nearly linear, with accelerometer sensitivity reaching 0.27 mV/(m·s). Moreover, the maximum error of the accelerometer was less than 0.037%.

Multi-Peptide Adsorption on Uncharged Solid Surfaces: A Coarse-Grained Simulation Study Research

Ruosang Qiu, Jie Xiao, Xiao Dong Chen

Engineering 2020, Volume 6, Issue 2,   Pages 185-194 doi: 10.1016/j.eng.2018.12.012

Abstract:

On-aim control of protein adsorption onto a solid surface remains challenging due to the complex interactions involved in this process. Through computational simulation, it is possible to gain molecular-level mechanistic insight into the movement of proteins at the water-solid interface, which allows better prediction of protein behaviors in adsorption and fouling systems. In this work, a mesoscale coarse-grained simulation method was used to investigate the aggregation and adsorption processes of multiple 12-Ala hydrophobic peptides onto a gold surface. It was observed that around half (46.6%) of the 12-Ala peptide chains could form aggregates. 30.0% of the individual peptides were rapidly adsorbed onto the solid surface; after a crawling process on the surface, some of these (51.0%) merged into each other or merged with floating peptides to form adsorbed aggregates. The change in the solid-liquid interface due to peptide deposition has a potential influence on the further adsorption of single peptide chains and aggregates in the bulk water. Overall, the findings from this work help to reveal the mechanism of multi-peptide adsorption, and consequentially build a basis for the understanding of multi-protein adsorption onto a solid surface.
