简介：专家知识广泛地被用来改进遥远地察觉到的分类精确性。通常，专家分类系统主要取决于DEM和一些题目的地图。在象素水平的空间关系信息通常被介绍进专家分类。因为地理目标被发现关系空间地依赖到某个度，在象素的空间关系信息的通常使用的基本单位极大地限制了空间信息的效率。寻找算法的一位基于补丁的邻居被建议实现专家分类。同类的光谱的联合起来，补丁，在空间目标被用作基本单位补丁鈥?关系信息的颗粒度，和不同类型通过寻找的一位空间邻居被获得算法。然后邻居信息和DEM数据被增加进专家分类系统并且过去常修改原始分类错误。在这，情况，沼泽地的分类精确性，草地和农田显然被改进。在这个工作，当水抽取方法的基础目标，和不同类型被测试在高精确性得到结果，水被使用。

简介：当前基于身份(标志)cryptosystem缺乏两大政党的认证和用户的私人钥匙的机制分发。一些基于标志的signcryption计划和基于标志的证实的关键协议协议被介绍了，但是他们不能完全解决这个问题。一个新奇基于标志的认证计划基于基于标志的加密(IBE)和指纹哈希方法被建议在IBE计划解决困难，它包括证实发送者的消息接收装置，证实用户并且把私人钥匙传给他们的信任权威(TA)。而且，计划从终端扩大指纹认证的应用程序到网络并且免于指纹数据制造。指纹认证方法由二个因素组成。这个方法联合一个标志例如，给USB钥匙调音，与用户由混合有指纹特征的一个假散乱数字的指纹回锅肉丁。安全和试验性的效率满足实际应用的要求。
