Visual Simulation Of Dynamic Burning Scene Of Single Plant, Weilong Ding, Linfeng Luo, Zheng Lei, Fuli Wu, Lifeng Xu
Journal of System Simulation
Abstract: At present, the research of the interactive process between plants and the flame mainly focuses on the visual simulation of forest fire scenario, but it is lack of the study on description of the interaction of individual plants and flame in detail. Aiming at this issue, this paper proposed a visual solution to model the process of a single plant burning. We established a plant model based on the branch node relationship and used particle system to model the flame. We set up a distance temperature field around a flame by using bounding sphere, and used a collision …

With the increasing availabilityof data in the logistics industry due to the digitalization trend, interest andopportunities for leveraging analytics in supply chain management to makedata-driven decisions is growing rapidly. In this paper, we introduce EzLog, anintegrated visualization prototype platform for supply chain analytics. Thisweb-based platform built by two undergraduate student teams for their capstonecourse can be used for data wrangling and rapid analysis of data from differentbusiness units of a major logistics company. Other functionalities of thesystem include standard processes to perform data analysis such as supervisedextraction, transformation, loading (ETL), data type validation and mapping.Weather, real-time stock market and Twitter …

Method Of Visualsimulation Of Rice Leaf Color, Hongyun Yang, Aizhen Sun, Wenji Yang, Huojiao He
Journal of System Simulation
Abstract: A color rendering method for rice leaves based on SPAD data distribution image was presented. Rice leaf image was collected and SPAD value was measured by field rice sample test. The relationship model between SPAD values and RGB value of leaf image was analyzed and constructed, and the R2 was 0.932 8, 0.833 1, 0.562 3 respectively. This showed that there was a correlation between SPAD and the red and green color of the leaf image. By the SPAD data distribution image, the spatial distribution of SPAD value on the leaf surface is described. The leaf surface color …

Journal of System Simulation
Abstract: Ocean data analysis is one of the important foundations in marine science research. Analysis on the sea surface temperature based on complex network theory helps explore the marine dynamics in a new perspective. The ocean is divided into grids, and the annual average of the sea surface temperature is calculated to reflect the properties of the corresponding grid area. The mutual information and the Pearson correlation coefficient are used to measure the similarity between different areas. The nonlinear and linear complex network models which reflect the station of the global marine climate can be built. Finally some popular measures …

Visualized Parameter-Tuned Algorithm For Control Loading System, Xie Chen, Shuchu Zhang, Zhenyu Sun
Journal of System Simulation
Abstract: To improve the fidelity of flight simulators, a control loading system is introduced in this paper which has the most direct effect on the pilot's intuitive perception. The overall design, hardware construction and digital simulation results of the system are given. In the process of system realization, the visual displacement-force loading configuration scheme is adopted to solve such problems as requirement changes or parameter excursions in hardware. The algorithm of output waveform curve adjustment based on cubic spline interpolation is proposed and the parameters are adjusted according to demand through graphical operation interface by maintenance personnel. The traditional method …

Journal of System Simulation
Abstract: As a kind of new design method, virtual reality has been widely used in military, industrial, construction, medical, aerospace and other fields. A method for designing and demonstrating the crew cabin of special vehicle by visualized virtual reality simulation technology is introduced in this paper, which takes the design and demonstration of crew cabin of special vehicle in the future as example. The overall framework has been formatted through the design of system function and the detailed division of module. On the basis of the design for each functional software of the system, the functional modules are effectively supported …
Multi-Scale Representation Of Battlefield Situation, Yafeng Huang, Xudong Li, Hangfeng Zhang
Multi-Scale Representation Of Battlefield Situation, Yafeng Huang, Xudong Li, Hangfeng Zhang
Journal of System Simulation
Abstract: This paper studies the multi-scale representation of battlefield situation at the conceptual level in different aspects, such as the concept of situation scale, scale transformation and typical styles of multi-scale representation. The scale of battlefield situation as the Cartesian product of two sets is defined, in which the first set contains space, time, and semantics; the other set contains breadth, granularity, and ratio. The scale transformation is classified into two types: scale downward and scale upward. The scale transformation is decomposed into three basic operations, i.e. breadth transformation, transformation and visualization derivation. The study points out that FIOP, LOD …
