Quadrature Element Vibration Analysis of Arbitrarily Shaped Membranes

The aim of the present study is to develop an efficient weak form quadrature element for free vibration analysis of arbitrarily shaped membranes.The arbitrarily shaped membrane is firstly mapped into a regular domain using blending functions,and the displacement in the element is assumed as the trigonometric functions.Explicit formulations are worked out for nodes of any type and a varying number of nodes.For verifications,results are compared with exact solutions and data obtained by other numerical methods.It is demonstrated that highly accurate frequencies can be obtained with a small number of nodes by present method.

新课标背景下小学语文“革命文化”题材类课文教学策略研究

在统编版小学语文教材中,“革命文化”题材类课文占据着重要地位。但是,“革命文化”题材类课文与当代的小学生之间存在着一定的时空、情感和认知距离与隔阂。如何基于核心素养,打造破“隔”求“融”、文道统一的品质课堂,通过此类课文教学对学生进行革命文化教育,已成为当前小学语文教师必须关注的热点问题。本文立足教学实际,紧扣统编版小学语文教材的主题单元编排特点和意图,分析小学语文“革命文化”题材类课文教学的原则,以期望对此类课文的教学策略进行探索与思考。

China rural financial different demands and hierarchical supply behaviors ——Model analysis from the perspective of mechanism design theory

Based on the ideas and framework of Mechanism Design Theory, the paper establishes model analysis on the differences rural financial demands and the choices of hierarchical supply behaviors, studies the relevant variables constraints choices on the rural financial supply and demand behavior, and thus presents a further improvement of the rural financial market variables, promotes the matching efficiency behavior selection between rural financial supply and demand, improves efficiency of the rural financial markets, strengthens financial supports for agriculture, rural areas and farmers.

Performance-based seismic financial risk assessment of reinforced concrete frame structures

Engineering facilities subjected to natural hazards(such as winds and earthquakes) will result in risk when any designed system(i.e.capacity) will not be able to meet the performance required(i.e.demand).Risk might be expressed either as a likelihood of damage or potential financial loss.Engineers tend to make use of the former(i.e.damage).Nevertheless,other non-technical stakeholders cannot get useful information from damage.However,if financial risk is expressed on the basis of probable monetary loss,it will be easily understood by all.Therefore,it is necessary to develop methodologies which communicate the system capacity and demand to financial risk,Incremental dynamic analysis(IDA) was applied in a performance-based earthquake engineering context to do hazard analysis,structural analysis,damage analysis and loss analysis of a reinforced concrete(RC) frame structure.And the financial implications of risk were expressed by expected annual loss(EAL).The quantitative risk analysis proposed is applicable to any engineering facilities and any natural hazards.It is shown that the results from the IDA can be used to assess the overall financial risk exposure to earthquake hazard for a given constructed facility.The computational IDA-EAL method will enable engineers to take into account the long-term financial implications in addition to the construction cost.Consequently,it will help stakeholders make decisions.

On Supply-side Reform

After the 2008 financial crisis, reality prompts people to reflect on the traditional theoretical frameworks of economics and the practical experiences based on macro-control and "demand management." The new reality also stimulates innovative efforts to "connect theory with practice" and leads academia and decision-makers to pay unprecedented attention to "supply management" regulation and structural supply-side reforms. Based on the theoretical innovation of the "new supply-side economics," this paper systematically discusses China's supply-side reform and its related issues from four levels—the innovation of closely connecting theory with practice, the problem-oriented innovation of re-making the momentum system under the new normal, the innovation for overall and long-term goals based on comprehensive planning and systematic engineering, and the innovation of institutional supply centered on reforms and modernization.

Innovative Services Models Based on ＂Four new＂ Economy

The propose of ＂four new＂ economy is to undertake innovation-driven transformation of Shanghai, promote the development of strategic emerging industries and transform and upgrade of manufacturing. In the following years, Shanghai will focus on the capture of key technologies, promoting the transformation of technology, expanding market demand, improving the development of the carrier, encouraging and supporting enterprises, financial institutions and social capital to increase the investment and use of＂four new＂ economy, to promote the ＂four new＂ economy gradually grow and develop. With the ＂four new＂ economy＇s development and growth, its service model should be changed too. On the basis of theory and practice, the text proposes three forms of innovative services models and relate recommendations to promote it.

ODE-Solver-Oriented Computational Method for the Structural Dynamic Analysis of Super Tall Buildings

The paper is to introduce a computational methodology that is based on ordinary differential equations （ODE） solver for the structural systems adopted by a super tall building in its preliminary design stage so as to facilitate the designers to adjust the dynamic properties of the adopted structural system. The construction of the study is composed by following aspects. The first aspect is the modelling of a structural system. As a typical example, a mega frame-core-tube structural system adopted by some famous super tall buildings such as Taipei 101 building, Shanghai World financial center, is employed to demonstrate the modelling of a computational model. The second aspect is the establishment of motion equations constituted by a group of ordinary differential equations for the analyses of free vibration and resonant response. The solutions of the motion equations （that constitutes the third aspect） resorted to ODE-solver technique. Finally, some valuable conclusions are summarized.

The Foundation for the Establishment of the BRICS New Development Bank:Immediate Impetus and Theoretical Rationale

The BRICS basic infrastructure suffers from a huge financing gap, but their massive foreign exchange reserves lack profitable outlets and member states＇ self-contained management costs are extremely high. The coincidence of the need for basic infrastructure investment and the need for profitable foreign exchange reserves are the immediate reasons for setting up the BRICS Development Bank. Comparative advantage and the co-movement of fluctuations in the BRICS member states optimize their cooperative interests. A co- movement game model analysis enables us to deduce the logical necessity for cooperation among the BRICS. Compared with other patterns of cooperation, virtual networks enable this financial cooperation to yield benefits in a short timeframe. The mutually supportive relationship between development and stability in the BRICS economies provides a solid rationale for the establishment of the New Development Bank.
