A Study of Digital Media Art Utilizing 2D Animation

This study is about the combination of PM technology and traditional animation. PM technology is Projection Mapping technology. Is from a combination of two words, Projection and Mapping. By using PM technology, to create a more excellent experience of vision or other senses than the traditional animation. This work is about produced by using PM technology, projecting the animation film on different objects (such as glass, buildings, trees, etc.) by using PM technology, to represent the changes of seasons. Although the same content, when projected on different objects, the visual effects are also different. Though the different visual effects, the viewer can get different visual experiences. To complete the study, I made some tests under various conditions: the first step, I projected the animation film on a small cube. The second step, I made tests on different regions of Kyushu University campus. By analyzing of the results of the tests, to make the future works more systematic

Intellectual Property Pledge Value Evaluation for Listed Companies: a Case Study of Yunnan Baiyao Enterprise

In modern enterprise assets, the proportion of intangible assets is not only an important standard to measure the competitiveness of an enterprise, but also an important way to obtain financing. Bank loans can be obtained through the pledge of intellectual property rights to solve the capital problems encountered in the development process of enterprises. However, the difficulty of intellectual property pledge is value evaluation, and intellectual property belongs to intangible assets, and its uncertain characteristics easily lead to more problems in the process of value evaluation. In addition, the traditional value evaluation methods have certain limitations. This paper selects Yunnan Baiyao enterprises as an example to study the value evaluation of intellectual property pledge of listed companies.In this paper, domestic and foreign scholars on the status of intellectual property pledge research, analysis of the focus of domestic and foreign research, at the same time, the status quo of value evaluation is analyzed, and combined with three basic methods of intellectual property value evaluation are analyzed, and taking Yunnan Baiyao enterprise as an example, the application of intellectual property pledge value evaluation method is illustrated, and relevant enlightenment and suggestions are obtained. Finally, this paper summarizes the full text and prospects the evaluation methods of intellectual property pledge value of Listed Companies in China. The text studies the advanced experience of municipal solid waste treat

Research on security risks and countermeasures of IPv6 network in the new era

In recent years, with the development of new infrastructure, especially the needs of 5G, Internet of Things, cloud services, data centers and other incremental large-scale construction, these “new increments” can be completely based on IPv6, or even pure IPv6 deployment to improve quality, reduce costs, and increase effi ciency. Therefore, in the process of constructing IPv6 network, how to ensure the overall security and stability of the network, and do a good job of network security protection and risk response to the maximum is very important. Based on this, this paper studies the security risk points of IPv6 network protocol and puts forward several security countermeasures for reference

Multi-Stage Expansion Planning for Decarbonizing Thermal Generation Supported Renewable Power Systems Using Hydrogen and Ammonia Storage

Large-scale centralized development of wind and solar energy and peer-to-grid transmission of renewable energy source (RES) via high voltage direct current (HVDC) has been regarded as one of the most promising ways to achieve goals of peak carbon and carbon neutrality in China. Traditionally, large-scale thermal generation is needed to economically support the load demand of HVDC with a given profile, which in turn raises concerns about carbon emissions. To address the issues above, hydrogen energy storage system (HESS) and ammonia energy storage system (AESS) are introduced to gradually replace thermal generation, which is represented as a multi-stage expansion planning (MSEP) problem. Specifically, first, HESS and AESS are established in the MSEP model with carbon emission reduction constraints, and yearly data with hourly time resolution are utilized for each stage to well describe the intermittence of RES. Then, a combined Dantzig-Wolfe decomposition (DWD) and column generation (CG) solution approach is proposed to efficiently solve the large-scale MSEP model. Finally, a real-life system in China is studied. The results indicate that HESS and AESS have the potential to handle the intermittence of RES, as well as the monthly imbalance between RES and load demand. Especially under the goal of carbon neutrality, the contribution of HESS and AESS in reducing levelized cost of energy (LCOE) reaches 12.28% and 14.59%, respectively, which finally leads to a LCOE of 0.4324 RMB/kWh.Comment: 10 pages, 8 figure

Plasma kinetics: Discrete Boltzmann modelling and Richtmyer-Meshkov instability

A discrete Boltzmann model (DBM) for plasma kinetics is proposed. The constructing of DBM mainly considers two aspects. The first is to build a physical model with sufficient physical functions before simulation. The second is to present schemes for extracting more valuable information from massive data after simulation. For the first aspect, the model is equivalent to a magnetohydrodynamic model plus a coarse-grained model for the most relevant TNE behaviors including the entropy production rate. A number of typical benchmark problems including Orszag-Tang (OT) vortex problem are used to verify the physical functions of DBM. For the second aspect, the DBM use non-conserved kinetic moments of (f-feq) to describe non-equilibrium state and behaviours of complex system. The OT vortex problem and the Richtmyer-Meshkov instability (RMI) are practical applications of the second aspect. For RMI with interface inverse and re-shock process, it is found that, in the case without magnetic field, the non-organized momentum flux shows the most pronounced effects near shock front, while the non-organized energy flux shows the most pronounced behaviors near perturbed interface. The influence of magnetic field on TNE effects shows stages: before the interface inverse, the TNE strength is enhanced by reducing the interface inverse speed; while after the interface inverse, the TNE strength is significantly reduced. Both the global average TNE strength and entropy production rate contributed by non-organized energy flux can be used as physical criteria to identify whether or not the magnetic field is sufficient to prevent the interface inverse.Comment: 20 pages, 15 figure

Optimal Sizing and Pricing of Renewable Power to Ammonia Systems Considering the Limited Flexibility of Ammonia Synthesis

Converting renewable energy into ammonia has been recognized as a promising way to realize ``green hydrogen substitution" in the chemical industry. However, renewable power to ammonia (RePtA) requires an essential investment in facilities to provide a buffer against the strong volatility of renewable energy and the limited flexibility of ammonia synthesis, which involves the three main stakeholders, namely, power, hydrogen, and ammonia. Therefore, the sizing and pricing of RePtA play a core role in balancing the interest demands of investors. This paper proposes an optimal sizing and pricing method for RePtA system planning. First, power to ammonia (P2A) is modeled as a flexible load, especially considering the limited flexibility of ammonia synthesis, which has been verified using real dynamic regulation data. Second, the multi-investor economic (MIE) model is established considering both external and internal trading modes. Then, a two-stage decomposed sizing and pricing method is proposed to solve the problem caused by the strong coupling of planning, operation, and trading, and information gap decision theory (IGDT) method is utilized to handle the uncertainty of renewable generation. Finally, real data from a real-life system in Inner Mongolia are utilized to verify the proposed approach. The results show that the system proposed has a yield of 8.15%.Comment: 10 pages, 10 figure
