简介：根据国家有关标准规定，凡更新地形图，都必须以新的图幅编号方法表示。而第一代地形图一律以旧式图幅编号方法表示为了方便新旧图号的互相检索，本文介绍了有关互换的数学模型，列举了互换例子，并据此编制了互换程序软件，可供各有关生产单位和组织生产部门参考使用

简介：针对传统分类方法精度不高、感兴趣目标分类不理想等缺陷，采用多特征组合的支持向量机影像分类方法，利用颜色矩、颜色集和灰度共生矩阵进行特征提取，总体精度、Kappa系数和混淆矩阵作为评价指标对单一特征、组合特征的不同分类结果进行分析。实验结果表明，该方法有效地解决了单数据源分类不完整、精度低等问题，对高维输入向量具有较高的推广力。

简介：[摘  要]摘要：随着社会经济的不断进步，施工模式的逐步更新，PPP模式已经成为施工的一项重要模式。建筑企业参与PPP总承包模式项目，既是机遇也是挑战。这种新颖的方式也势必会带来不同于常规工程的过程管理问题。因此，PPP项目建设期的成本控制就存在一定难度，必须明确这种新模式的特点，制定具有针对性的成本管理措施,梳理建设期各环节的管理重点，必须要做好PPP总承包项目模式的风险防控研究以及成本管控措施，才能使PPP项目真正落地开花。本文以TJ地铁X号线工程为例，通过对本项目充分调研找出了本项目3大风险点、5大成本管控手段，通过分析和实践在工程的各个阶段制定相应的措施，保障PPP项目效益。
