The aim of this study is to verify the impact of Employee Career Growth on task performance. This paper also analyze the mediating effect of organizational identification and the moderating effect of self-efficacy. Based on theoretical research, this study proposes 3 key research hypotheses and established a research model. Employee career growth is positively related to task performance, organizational identification as the mediating variable and self-efficacy as the moderating variable effect employee career growth and task performance. This research provides a new way of thinking about how to improve employees’ task performance and how to promote the working efficiency of the company from the perspective of employee career growth. Companies should instruct employees to appropriately integrate personal career growth goals with corporate development goals. In terms of measures on maintaining employees’ degree of recognition, companies should not only ensure material rewards, but also do well in providing non-material guarantees and incentives, so as to enhance the organizational identification and working initiative of employees, and improve the efficiency of the company.

Mao Yang,Jianting Zhou,Qingyuan Zhao,Qianwen Xia,Hong Zhang,Lifeng Wang 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.1

In order to solve the problem of quantitative detection of corroded reinforced concrete of different sizes, the quantitative detection experiment based on spontaneous magnetic flux leakage (SMFL) was carried out in batches. Electrochemical corrosion of 27 reinforced concrete specimens was carried out, and the SMFL signals of reinforcement were obtained by magnetic detection equipment. Four-dimensional magnetic indicators M1-M4 that can characterize the corrosion degree of the specimens were defined. The influence of different sizes on the magnetic indicators were analyzed. It is concluded that the thicknesses of the concrete covers affect the magnetic indicators by affecting the lift-off heights z. The influence of diameter of the rebars on the quantitative detection can be eliminated by describing the corrosion degree with the average cross-section loss rate α. The influence of length of the rebars on quantitative detection is not clear yet. Finally, Support Vector Machine (SVM) was introduced to establish a classification model of corrosion classes and magnetic indicators. Using the model to predict the corrosion classes of the specimens can achieve a high classification accuracy. The research provides a new method for the quantitative detection of steel corrosion.

Composite Design of Disturbance Observer and Reentry Attitude Controller: An Enhanced Finite-time Technique for Aeroservoelastic Reusable Launch Vehicles

Zhenshu Yang,Jianzhong Yang,Qi Mao,Liqian Dou,Qun Zong 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.8

In this paper, we concern the reentry attitude control (RAC) scheme design for aeroservoelastic reusable launch vehicles (RLVs). The basic problem is to derive a RAC technique such that the aeroservoelastic RLV can achieve a robust tracking of the desired attitudes in a rapid way despite the existence of parameter uncertainties as well as external disturbances. Following from the elastic equations and attitude dynamics of the RLV, we formulate a control-oriented model in matched structure. Our main contribution is threefold. First, using the fast terminal sliding mode algorithm, the disturbance observers are designed to generate the estimation of uncertainties and disturbances, while can ensure the estimation errors converge to the origin within a timely fashion. Second, the finite-time super-twisting sliding mode control method and cascade-loop design are developed to incorporate into the new RAC strategy; hence it leads to a guaranteed tracking ability of the reentry attitude in a timely way. Third, a finite-time integral sliding mode filter is proposed in the control scheme such that the virtual input signal can be tackled well. Additionally, numerical simulations of a dynamic model for the RLV are implemented to demonstrate the effectiveness and performance of the developed RAC strategy and furthermore its aeroservoelastic properties.

Pressure-Induced Confined Metal from the Mott InsulatorSr3Ir2O7

Ding, Yang,Yang, Liuxiang,Chen, Cheng-Chien,Kim, Heung-Sik,Han, Myung Joon,Luo, Wei,Feng, Zhenxing,Upton, Mary,Casa, Diego,Kim, Jungho,Gog, Thomas,Zeng, Zhidan,Cao, Gang,Mao, Ho-kwang,van Veenendaal, American Physical Society 2016 Physical Review Letters Vol.116 No.21

<P>The spin-orbit Mott insulator Sr3Ir2O7 provides a fascinating playground to explore insulator-metal transition driven by intertwined charge, spin, and lattice degrees of freedom. Here, we report high-pressure electric resistance and resonant inelastic x-ray scattering measurements on single-crystal Sr3Ir2O7 up to 63-65 GPa at 300 K. The material becomes a confined metal at 59.5 GPa, showing metallicity in the ab plane but an insulating behavior along the c axis. Such an unusual phenomenon resembles the strange metal phase in cuprate superconductors. Since there is no sign of the collapse of spin-orbit or Coulomb interactions in x-ray measurements, this novel insulator-metal transition is potentially driven by a first-order structural change at nearby pressures. Our discovery points to a new approach for synthesizing functional materials.</P>

Micromechanical modeling for viscoplastic properties of enzyme degradable semi-crystalline poly (ε-caprolactone)

Xinwei Yang,Cheng Yang,Shujuan Hou,Yiqi Mao 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.11

This work provide theoretical understandings for the enzyme-degradable PCL, and assist its structural designs and engineering applications. An energy-dependent evolution model is developed to reflect the enzyme-triggered decrystallization of crystals and the further dissolution by applying a chain-broken chemical reaction. Then, the mechanical properties of the enzyme-degradable semicrystalline PCL is modelled through the homogenization-based procedure by the volume-average of a collection of laminated inclusions with crystals and amorphous phase. A dual-phase-lag diffusion model is advanced to solve the enzyme concentrations in the PCL. The model is calibrated by the experiments and then applied for the chemomechanical properties of the PCL when under enzyme conditions. Some numerical examples are conducted to discuss effects of the enzyme concentration and the crystallinity on the crystallographic axe evolution as well as the overall chemomechanical properties of the semicrystalline PCL.
