Structured expression and similarity comparison are the most important jobs in video retrieval. 视频结构化表征和基于这种表征进行相似度比较是视频检索的前提和最基础的重要工作。
The Object Oriented Model Structured Expression(SE) Based on Class, which is composed of Model frame, Model class and Model instance, is studied and used in Reactor simulation for natural gas plasma synthesizing ethene & ethane. 提出了基于类面向对象的模型结构化表达方法,形成由模型框架、模型类和模型实例构成的继承层次,并应用到天然气等离子体合成乙烯乙炔反应器模拟研究中。
The semantic model contained the basic elements of the critical appraisal of medical evidences. There were 7 categories, 27 sub-categories and 87 semantic slots ( properties ) and the metadata. The implementation of the model structured and formal expression was accomplished. 本研究构建了包含证据评价基本要素的语义模型,创建了7个类、27个子类和87个语义槽(属性)和元数据,并实现了模型的结构化和形式化表达。
The paper has structured dynamic mathematical expression of national income, has simulated combined effect of multiplier and accelerator, and analyzed effect of multiplier and accelerator to growth and fluctuations of national economics by control theory. 本文建立了国民收入动态模型,模拟了加速数与乘数对国民经济的组合效应,并按照控制理论讨论了加速数与边际消费系数取值同国民经济增长与波动的关系。
The article defines order-preserving transform of bounded monotone functions on the symmetric interval [ - 1,1 ], and applies the methods of fuzzy structured element, the expression forms and correspondent membership of the four fundamental operations of fuzzy numbers based on the fuzzy structured element is obtained. 为了解决模糊数计算上的困难,引入了区间[-1,1]上单调函数的某些同序单调变换,利用模糊结构元理论,将模糊数的四则运算转换为同序单调函数之间的相应运算。
