1步信息脉冲牵引控制的多智能体一致性分析
多智能体系统 一致性 l步信息 脉冲牵引控制
2022/3/15
应用矩阵论和代数图论，分析l步信息脉冲牵引控制的多智能体一致性问题。把具有单个脉冲控制器的多智能体的一致性系统推广到只对一个智能体实施l步信息脉冲牵引控制的系统。在通讯拓扑是无向连通图的情况下，给出使多智能体达到一致性的一个充分条件。选择恰当的l有助于减少使多智能体系统达到一致性所需的脉冲次数。最后，仿真实例验证了理论结果。
基于广义霍夫变换的粘连字符验证码的识别
验证码识别 粘连字符 广义霍夫变换 骨架化
2022/3/30
针对具有粘连字符的验证码，提出了一种基于广义霍夫变换的识别算法。首先，对验证码图片和字符模板进行预处理和骨架化，提取字符模板中目标点的局部特征保存到参考表中；然后，对验证码图片进行逐像素比较，并进行投票，通过投票累加器的极大值定位出字符模板的参考点；最后，对相邻字符之间的干扰进行分析处理，从而提高了字符识别的正确率。提取的局部特征具有平移和旋转的不变性，因而可以对验证码图片中出现的字符部分形变、字...

移动载荷黏弹性Pasternak地基梁动力学响应
黏弹性地基 梁 移动载荷 二维Fourier变换 留数定理
2013/12/4
通过积分变换研究移动载荷激励下无限长黏弹性Pasternak地基梁在复数域上的封闭解.通过二维Fourier变换得到梁变形的Green函数，再运用Fourier逆变换得到梁变形的积分表达式,对解析表达式应用留数定理得到系统在复数域上的封闭解.数值研究梁和地基的参数对梁变形的影响，表明Pasternak基础中的黏性和剪切力对梁变形的影响明显.采用样条插值对积分解析表达式求数值解，验证封闭解的有效性.
