LL1文法分析
该代码是自己原创,参考编译原理的书,根据LL1文法判断过程编写而成,进行了多种判断,找左公因子,左递归,求first集,follow集,select集最终根据select集判断出是否为ll1文法,并且在过程中每个产生式是否能产生空,其select集,first集,follow集,均可打印出

A Reader Anti-collision Protocol for RFID-Enhanced Wireless Sensor Networks
资源描述Abstract Considering rapid developments in the technologies of both radio-frequency identification
(RFID) systems and wireless sensor networks (WSN), an integration of the two
technologies may lead to the formation of an RFID-enhanced WSN which would possess
improved functions and capabilities. In the RFID-enhanced WSN, many reader-enhanced
nodes have increasingly been employed. In such networks, RFID data contains a lot of duplication,
because the same tag may be read multiple times, and collision may occur among
readers, while energy constraints are also a serious problem. These three could in turn cause
serious problems. In this paper, we have proposed our CSMA-based algorithm since it is light,
efficiently minimizes all kinds of reader collision, and eliminates the duplicate data. For this
purpose, we have used a separate control channel and a tag ID forwarding mechanism with a
special co

Freak算法
应用背景大量视觉应用依赖于整个图像匹配关键点。在过去的十年中对功能更快,更稳健的关键点和关联算法族群包括:尺度不变特征变换(SIFT),提速强大的功能(SURF),以及最近的二进制稳健不变可扩展关键点(BRISK),仅举几例。关键技术我们提出了一个新的关键点描述符的灵感来自于人类视觉系统和更精确的视网膜上,创造了快速视网膜关键点(FREAK)。二进制串的级联是通过有效地在视网膜的采样模式比较图像强度计算。
