Analysis of Unbalanced Growth Caused by Foreign Direct Investment in China’s Regional Economy

Since reform and opening up in 1979, China’s national economy has grown rapidly, and thenational economic strength has been continuously enhanced. However, the regional economy hasnot grown in a balanced way. Economic imbalances in China’s three regions (eastern, central,and western) has become increasingly large. The eastern region has become the largest beneficiary area for absorption of foreign direct investment (FDI), while the central and westernregions have absorbed less, a trend of “high in the east and low in the west.” Undoubtedly, FDI plays an important role in promoting China’s economic growth and has become an important part of China’s national economy. However, facts that have proved the expansion of regional economic differences has become a serious problem, which has had an impact on the national economy and social development. This paper analyzes the regional economic differences in China after reform and opening up, analyzes the main problems affecting the regional economic differences in China, and then puts forward suggestions for narrowing the regional economic differences and building a harmonious society

Prioritized Planning for Target-Oriented Manipulation via Hierarchical Stacking Relationship Prediction

In scenarios involving the grasping of multiple targets, the learning of stacking relationships between objects is fundamental for robots to execute safely and efficiently. However, current methods lack subdivision for the hierarchy of stacking relationship types. In scenes where objects are mostly stacked in an orderly manner, they are incapable of performing human-like and high-efficient grasping decisions. This paper proposes a perception-planning method to distinguish different stacking types between objects and generate prioritized manipulation order decisions based on given target designations. We utilize a Hierarchical Stacking Relationship Network (HSRN) to discriminate the hierarchy of stacking and generate a refined Stacking Relationship Tree (SRT) for relationship description. Considering that objects with high stacking stability can be grasped together if necessary, we introduce an elaborate decision-making planner based on the Partially Observable Markov Decision Process (POMDP), which leverages observations and generates the least grasp-consuming decision chain with robustness and is suitable for simultaneously specifying multiple targets. To verify our work, we set the scene to the dining table and augment the REGRAD dataset with a set of common tableware models for network training. Experiments show that our method effectively generates grasping decisions that conform to human requirements, and improves the implementation efficiency compared with existing methods on the basis of guaranteeing the success rate.Comment: 8 pages, 8 figure

Error assessment method of electromechanical–electromagnetic hybrid simulation

With ultra high voltage direct current (UHVDC) and flexible alternating current transmission systems (FACTS) have been widely applied in power system, the AC/DC power grid is constantly extending which makes its composition more complicated. The independent electromechanical transient simulation and electromagnetic transient simulation cannot meet the need of rapidly developing modern power system in simulation technology. Electromechanical–electromagnetic hybrid simulation not only has the advantages of analysing large systems, but also accurate description of power electronic components. Analysing errors in hybrid simulations can help them to quantitatively analyse different hybrid simulation interface technologies to optimise simulation settings. Concerned fault types, fault location, and point fault cleaning time, an electromechanical–electromagnetic hybrid simulation scenarios probabilistic model based on Monte Carlo is put forward. Then adopt Prony method to quantitatively analyse the hybrid simulation errors. Through a typical example of UHVDC power grid in Shandong province, the error evaluation method of the hybrid simulation is demonstrated in detail. The research shows that this kind of assessment method can well analyse the numerical validity of hybrid simulation

Design and implementation of the integrated experiment cabinet for micro-transmission lines

Micro-transmission lines are the physical model elements that own the same physical properties as the real transmission lines in power system, which are the significant components of a micro-dynamic simulation laboratory. This study presents an integrated experiment cabinet for micro-transmission lines (IECMTL). IECMTL integrates 20 micro-emulating transmission lines units, four micro-bus units and two light-synchronised phasor measurement units (PMU Lights). Benefitting from the same size and interface, researchers can change the position and wiring of any two transmission lines units according to the needs of the simulation experiment. PMU Lights are employed to get the operating status of micro-emulating transmission lines, including three-phase frequency, voltage phasor and current phasor. Appropriate software was developed on server to communicate with IECMTL in a two-way manner through the internet. Real-time monitoring and control features of IECMTL provide a flexible physical platform not only for innovative research ideas but also for education engineering of the power system. An example test-bed consisting of two IECMTLs was presented to simulate the power grids containing three generators and nine buses
