在分析超图和作战协同相关概念基础上,采用形式化方式对抽象化的作战协同关系进行了描述,定义了协同关系矩阵,创新性地根据超图相关概念构建了作战协同超图模型,并根据模型定义了顶点度和关联系数等支持作战协同关系分析的特征参数。通过实验建立了某想定数据中的火力协同关系超图模型,并进行了度和关联系数的分析,实验结果证明了作战协同关系超图模型的可用性。 相似文献

为提高图像配准算法的精度和适应能力，将超图约束和改进归一化互相关方法应用于图像配准。利用Hessian-Affine检测得到的仿射不变区域代替固定窗口来改进归一化互相关方法，获得初始匹配点对；通过马氏距离计算超边间的相似度，采用超图约束计算匹配分数对匹配对进行排序；利用分数高的部分匹配点对初始化变换矩阵，通过过滤匹配对来循环更新得到最优变换矩阵实现配准。实验结果表明，该方法具有较好的匹配和剔除错误匹配的效果，在不同类型的图像配准中也有较好的配准效果。 相似文献

本文从大系统特点和存在问题出发,讨论系统结构的意义和现状,建立大系统超图结构模型(总体结构),进而讨论亚结构。并在总体结构与亚结构研究基础上,引出系统结构若干原则。考虑国内大系统实践某些正、反两方面经验,对于A.D.Hall等关于系统工程方法论框架研究:[8]、[9]、[10]、[11],试图作以下发展: 1.建立并证明诱导关系划分存在定理和划分加细序列诱导层次结构定理。试图为大系统结构研究,提供初步理论依据。2.将国外只研究二元关系结构,发展为具有n-元关系,以及高阶关系的更一般结构。3.将BERGE的超图[13]应用到复杂结构研究中来,并定义大系统结构的有限闭包。试图扩大系统结构研究的眼界和应用范围。 相似文献

设H是一个超图（图），对于它的一个k边着色c：E（H）→{1，2，∧k}，我们记f（H，c）是由k种颜色中，由同一色类导出的子超图（子图）中所含分枝数最少的子超图（子图）的分枝数。fk（H）表示H中所有k边着色中f（H，c）的最大值，即fk（H）=maxf（H，c）。本文主要研究了路、Ti’、广义θ-图的成分着色，并得到了fi（Pn）=（n-1/k,f（Ti^＊）=[i-1/k]＋1∫k（Gθ）=2 相似文献

利用K类函数改进了马尔金定理的一个结论（即在非注定系统中，若相关的定正函数V和定负函数V1满足limt→∞(dV/dT-V1)=0，则系统有稳定的平凡解），得到一个非驻定系统平凡解的稳定性定理，并通过实例说明本文给出的定理可以判别其平凡解的稳定性，而用马尔金定理的结论失效。 相似文献

多基线相位解缠绕的性能深受噪声水平制约，比如基于经典中国余数定理的相位解缠方法，由于其糟糕的抗噪声性能，限制了其在实际中的广泛运用。基于搜索鲁棒的余数定理，通过引入公因子，构建新的同余方程组，提出了一种搜索鲁棒的中国余数定理的相位解缠方法。仿真实验验证了该方法的有效性，并表明选择合理的公因子可以有效提高算法的抗噪声性能。 相似文献

Thermal batteries are unique direct current (DC) electrical power sources with long shelf live, high reliability and higher power density than classical alkaline batteries. This paper gives a brief overview into the working principle of thermal batteries and reviews the properties of zirconium/barium chromate (Zr/BaCrO4) pyrolant previously used as first fire and iron/potassium perchlorate (Fe/KClO4) pyrolant (Heat), commonly applied as heating pellet in thermal batteries and its hazard properties. The review gives 64 references to the public domain. CAS-Nos. Zr: [7440-67-7], BaCrO4: [10294-40-3], Fe: [7439-89-6], KClO4: [7778-74-7], Viton: [9011-17-0].CAS-Nos.

如何提高中小型石油库(站)设计的效率是工程设计人员非常关注的一个问题,也是中小型石油库(站)工程设计CAD软件开发的基本目标之一,但目前在国内研究较少。分析归纳了中小型石油库(站)实际设计中的典型设计方法,提出了以外部数据库和图形数据库为基础,采用基于工程参数驱动图块的设计技术、基于单元图的设计技术、基于工程定型图的设计技术,并结合根据需要开发的修改编辑工具,为设计人员提供了一整套设计工具,帮助其实现快速设计。试用效果证明,该思路切实可行,并已在中小型石油库(站)CAD系统的开发中得以实现。 相似文献
