| 1 | Strengthening the Mechanical Performance of Sea Urchin Skeleton by Tube Feet Pore显示文摘In this paper,the effects of tube feet pores on the mechanical properties of Sea Urchin Skeleton (SUS) have been studied.The pore structure of drop-like Tripnenstes gratilla (a sea urchin) skeleton is characterized by Scanning Electron Microscopy (SEM).Based upon the data,the finite element method has been employed to analyze the Maximum Tensile Stress (MTS) of SUS models with different pore positions,accompanied by compressive tests on SUS-like ceramics.Results indicate that for a drop-like SUS,the MTS keeps a linear relationship with the maximum load applied on the SUS.More importantly,the mechanical performances of some perforated SUSs are better than their non-perforated counterparts due to their lower MTS values,e.g.the maximum load can thus be increased by 35% when the pore is perforated at-10°.The strengthening is attributed to the introduced pore that causes the redistribution of stress and partly reduces the stress intensity on the original MTS position.By contrast,the pore only increases the MTS value of a spherical shell under isostatic pressure or unidirectional pressing.This is a strong hint that the drop-like shape of SUS has evolved to work with the tube feet pores to better protect their bodies. | Hui Yu Tianye Lin Yu Xin Jianlin Li Jianbao Li Yongjun Chen Xianzhi Chen Longyang Liu | 2019 | Journal of Bionic Engineering2019，16，1： | 0 |
| 2 | WaveLines:towards effective visualization and analysis of stability in power grid simulation显示文摘Closely related to the safety and stability of power grids,stability analysis has long been a core topic in the electric industry.Conventional approaches employ computational simulation to make the quantitative judgement of the grid stability under distinctive conditions.The lack of in-depth data analysis tools has led to the difficulty in analytical tasks such as situation-aware analysis,instability reasoning and pattern recognition.To facilitate visual exploration and reasoning on the simulation data,we introduce WaveLines,a visual analysis approach which supports the supervisory control of multivariate simulation time series of power grids.We design and implement an interactive system that supports a set of analytical tasks proposed by domain experts and experienced operators.Experiments have been conducted with domain experts to illustrate the usability and effectiveness of WaveLines. | Tianye ZHANG Qi WANG Liwen LIN Jiazhi XIA Xiwang XU Yanhao HUANG Xiaonan LUO Wenting ZHENG Wei CHEN | 2021 | Frontiers of Computer Science2021，15，6： | 0 |
