Signal propagation on deformable patterns with reaction-diffusion system

提出了反映信号传播历史的分裂斑离散斑图形成模型，作为时变局部斑图的描述。在以适当的速率恒定地供给用于产生光斑的生长因子的条件下，分裂光斑各向同性地移动。至于信号传播，根据介质的形状，观察到单向信号传播、信号故障、多个信号的滤波和自主递归信号生成。结果表明，利用上述信号特征可以实现信号融合和包含时间信息的布尔运算，

Discrete pattern formation model of splitting spot that reflect the history of signal propagation was proposed as a description of time variable local pattern. The splitting spot moves isotropic in the condition that growth factor for spot generation is supplied constantly at suitable rate. As for signal propagation, uni-directional signal propagation, signal failure, filtering of plural signals, and autonomous recursive signal generation were observed depending on media's shape. It was shown that signal fusion and Boolean operation including time-information can be realized utilizing above signaling features,
