Innovation Design Study on E- Bidding System: Chinese Enterprise Group experience

The e-bidding platform of electric enterprise group purchase business is regard as a complex system of interrelated economic, organizational, social and elements as well as the external and internal information flows of a company. Getting positive synergistic effect is one of the important factors for the enterprise group procurement business innovation. The paper showcase the synergistic effect framework, and then study synergistic effect of the e-bidding platform based on complex adaptive theory .We sharp enterprise group purchase system, research how to get positive synergistic effect contributions to the enhancement of the efficiency of the business overall

Study on E- Business Platform of Electric Enterprise Group Based on the Perspective of System Synergy

the paper showcase the synergistic effect framework and apply it to a study on electricity energy groups of internet bidding platform on B2B supply business. We enumerate electricity grid enterprise group’s purchase system. Since 2006, by setting up the multi-layer purchase system based on internet. Chinese energy enterprise group began to adopt internet supply platform and take full advantage of synergistic effect and scale effects, decrease the trade cost of whole supply chain. From the perspective of system synergy, the paper firstly analyzed the model building on e-procurement platform, and then offered a set of evaluation index on synergistic effect, lastly through empirical analysis, point out there is not only positive synergistic effect but also negative synergistic effect on the e-business platform of the purchase system

Spontaneously-Induced Dirac Boundary State and Digitization in a Nonlinear Resonator Chain

The low-energy excitations in many condensed matter and metamaterial systems can be well described by the Dirac equation. The mass term associated with these collective excitations, also known as the Dirac mass, can take any value and is directly responsible for determining whether the resultant band structure exhibits a band gap or a Dirac point with linear dispersion. Manipulation of this Dirac mass has inspired new methods of band structure engineering and electron confinement. Notably, it has been shown that a massless state necessarily localizes at any domain wall that divides regions with Dirac masses of different signs. These localized states are known as Jackiw-Rebbi-type (JR-type) Dirac boundary modes and their tunability and localization features have valuable technological potential. In this study, we experimentally demonstrate that nonlinearity within a 1D Dirac material can result in the spontaneous appearance of a domain boundary for the Dirac mass. Our experiments are performed in a dimerized magneto-mechanical metamaterial that allows complete control of both the magnitude and sign of the local material nonlinearity, as well as the sign of the Dirac mass. We find that the massless bound state that emerges at the spontaneously appearing domain boundary acts similarly to a dopant site within an insulator, causing the material to exhibit a dramatic binary switch in its conductivity when driven above an excitation threshold

Simulation on Phase Change Thermal Storage Panel Based on Capillary Network

AbstractStorage technology has the advantage to solve the problem of the not matching in time and space of energy's supply and demand, making it an effective way to the rational use of resources and reducing environmental pollution. What is used in this paper is a regular flat phase change heat storage module packaging with capillary network and phase change material. In this paper, the software Fluent was used to simulate the impact factors and the ways to enhance heat transfer in the process of phase change. The simulation result indicates that: During the melting process, because of the influence of natural convection, the top of phase change regional melts faster, the temperature contour ramp to top. The higher the horizon is, the temperature contour is more stable. Natural convection play different role in the melting and solidification process, which accelerated melting rate in the melting process, and slowed down in solidification. The surface temperature of phase change thermal storage panel will be maintained at 26.5°C, within the limits of human body comfort and is able to improve the air temperature within a certain space
