Research on Coordination between Industrial Structure and Employment Structure in Shandong Province

Industrial structure has been continuously optimized and upgraded with the rapid development of economy in Shandong Province since1980. On the basis of summarizing the changes of industrial structure and employment structure in Shandong Province,the coordination between industrial structure and employment structure in Shandong Province was analyzed by using structure deviation degree and coordination coefficient,and some suggestions to promote the coordinated development of industrial structure and employment structure were put forward according to the practical situations of Shandong Province.

Simultaneous optimization and control for polypropylene grade transition with two-layer hierarchical structure

In this paper,a two-layer hierarchical structure of optimization and control for polypropylene grade transition was raised to overcome process uncertain disturbances that led to the large deviation between the open-loop reference trajectory and the actual process.In the upper layer,the variant time scale based control vector parametric methods(VTS-CVP) was used for dynamic optimization of transition reference trajectory,while nonlinear model predictive controller(NMPC) based on closed-loop subspace and piece-wise linear(SSARX-PWL) model in the lower layer was tracking to the reference trajectory from the upper layer for overcoming high-frequency disturbances.Besides,mechanism about trajectory deviation detection and optimal trajectory updating online were introduced to ensure a smooth transition for the entire process.The proposed method was validated with the real data from an industrial double-loop propylene polymerization reaction process with developed dynamic mechanism mathematical model.

A Quantitative Study on the Relationship between Industrial Structure and Employment Structure in Yulin

Reasonable industrial structure can promote the benign development of employment structure, and the coordination of the employment structure but also for industrial restructuring and upgrading to lay a solid foundation. This article take Yulin as an example, uses 1990-2014 year three industrial output value and the employment population statistical data, uses the statistics gauging device that has conducted the quantitative investigation to the Yulin industrial structure and the employment structure relations. First, this paper describes the evolution process of Yulin’s industrial structure and employment structure. Secondly, it uses the correlation analysis to confirm the strong correlation between Yulin’s industrial structure and employment structure, then, from the industrial structure deviation and employment elasticity, and the second industry, the first industry, labor surplus. Finally, according to the research income, gives the rational distribution of industrial layout to promote employment growh in the third industry and the policy recommendations.

Industrial and Employment Structural Imbalance in Northeast China and Agricultural Enhancement

Balanced development between industrial and employment structures are important indicators of regional economic and social health. By introducing indicators such as industrial structure deviation, comparative labor productivity, international comparison of relative labor productivity as well as employment elasticity, the paper further probed into intricate causes for the imbalance between industrial and employment structures in this specific region from a new angle which based on the evolution process analyses of both industrial and employment structures in Liaoning, Jilin and Heilongjiang in Northeast China. The paper also suggested policy measures to strengthen agricultural developments and to facilitate the balance between industrial and employment structures.

Strategically supported cooperation in dynamic games with coalition structures

The problem of strategic stability of long-range cooperative agreements in dynamic games with coalition structures is investigated. Based on imputation distribution procedures, a general theoretical framework of the differential game with a coalition structure is proposed. A few assumptions about the deviation instant for a coalition are made concerning the behavior of a group of many individuals in certain dynamic environments.From these, the time-consistent cooperative agreement can be strategically supported by ε-Nash or strong ε-Nash equilibria. While in games in the extensive form with perfect information, it is somewhat surprising that without the assumptions of deviation instant for a coalition, Nash or strong Nash equilibria can be constructed.

Amplified random fiber laser-pumped mid-infrared optical parametric oscillator

In this Letter, we report, for the first time to our knowledge, on a continuous-wave, singly resonant optical parametric oscillator using an Mg O： PPLN crystal pumped by an all-fiberized master-oscillator power amplifier structured amplified random fiber laser. An idler output power of 2.46 W at 3752 nm is achieved with excellent beam quality, and the corresponding pump-to-idler conversion efficiency is 9.6% at room temperature. The idler output power exhibits a peak-to-peak power stability better than 12.7%, and the corresponding standard deviation is better than 3.6% RMS in about 20 min at the maximum output power. Meanwhile, other characteristics of the generated signal and idler laser are studied in detail and not only offered an effective guide in the research of optical parametric processes in the case of a continuous spectrum, but also broadened the range of random fiber laser applications.
