Research on the Realization Mechanism of and Approach to Ecological Product Valuations

Ecological product is an innovative practice for ecological valuations in China. Due to the influence of historical conditions and development stages in China, research on the realization of ecological valuations has lagged. In the new era, the construction of an ecological civilization guided by the "Two Mountains" theory has been promoted to the national strategic level and is supporting the growth of theoretical research and practical exploration based on the understanding of ecological product values. We want to innovate and improve the system used to realize the value of ecological products by applying the existing research, which focuses on the concept definition of ecological products and their correlation theories. Through systematic expansion and upgrades in this system, the evaluation accuracy of ecological products can be improved, providing valuable references for further practical exploration and promoting an ecological culture in China.

Reference unification and reference linking:Concept,functionalities and inhibiting elements.A case study of Chinese Science Citation Database

In comparing reference unification to reference linking,the authors found that reference linking yield similar result as that of reference unification.An investigative study was conducted by these authors at Chinese Science Citation Database(CSCD)of National Science Library(NSL)of the ChineseAcademy of Sciences(CAS),it was found that there were three inhibiting elements in invoking a reference unification solution and the same is true for a reference linking solution.Firstly,it was difficult to define a minimum set of data elements for matching.Secondly,it had a problem of data inaccuracy and/or data incompleteness.Thirdly,it was hard to determine an appropriate linking result that produced the desired document for the user.Thus these authors suggest that getting Digital Object Identifier(DOI)for each journal article is a good way to bring about reference unification and also to improve metadata quality simultaneously at the same time.Therefore,DOI has a pivotal role to play in terms of bringing about reference unification and/or a reference linking.

A Characterization for Dominant Strategy Implementation

We introduce a perfect price discriminating mechanism for allocation prob- lems with private information. A perfect price discriminating mechanism treats a seller, for example, as a perfect price discriminating monopolist who faces a price schedule that does not depend on her report. In any perfect price discriminating mechanism, every player has a dominant strategy to truthfully report her private infor- mation. We establish a characterization for dominant strategy implementation： Any outcome that can be dominant strategy implemented can also be dominant strategy implemented using a perfect price discriminating mechanism. We apply this charac- terization to derive the optimal, budget-balanced, dominant strategy mechanisms for public good provision and bilateral bargaining.

Elastic energy storage technology using spiral spring devices and its applications:A review

Harvesting and storing energy is a key problem in some applications.Elastic energy storage technology has the advantages of wide-sources,simple structural principle,renewability,high effectiveness and environmental-friendliness.This paper elaborates the operational principles and technical properties and summarizes the appli-cability of elastic energy storage technology with spiral springs.Elastic energy storage using spiral spring can realize the balance between energy supply and demand in some applications.Continuous input-spontaneous out-put working style can provide simple energy sources for short-time energy supply,and provide strong moment impact and rapid start,or realize the energy conservation for reciprocating movement.Uniform output working style can realize energy output with uniform speed for timekeeping and load-driving.Random input working style can harvest and store random mechanical energy or convert small torque into a large moment to drive external loads.Finally,this paper proposes new researches and developments of elastic energy storage technology on new materials and structures,mechanical properties and structural dynamics analyses,design and control for new functions.

A Synthetic Framework for Evaluating and Designing an Anthropomorphic Prosthetic Hand

The mimic of aesthetics, fianction, and rehabilitation application makes the prosthetic hand design an interdisciplinary, synthetic work. Prosthetic hands should be designed in a comprehensive consideration with a synthetic framework from multiple areas. In this case, a synthetic framework containing 12 anthropomorphism indexes is established and utilized to understand the human hand characteristic and quantifiably evaluate the anthropomorphism of a prosthetic hand. Our quantified evaluation results show that a Global Anthropomorphic Score （GAS） of the current commercial prosthetic hands is only 45.2%. The compliance, coupling speed ratio and configuration of the Degrees Of Freedom （DOF） are found to be the lowest three anthropomorphism evaluation indexes in all 12 indexes. In addition, a design priority is proposed based on the quantified evaluation results and contributes to a prosthetic hand design. Moreover, our correlation analysis results between each index and GAS show that, compared with the conventional evaluation index-grasp gesture, the rotation axis distribution index has a stronger distinguishing capability to the hand performance. Finally, a flowchart of prosthetic hand design was presented for a designer to design a prosthetic hand with a high anthropomorphism.
