多维傅里叶变换，二维DFT快速算法，共分五部--二：二维复序列行列算法-Multi-dimensional Fourier transform, fast algorithm for two-dimensional DFT is divided into 5- 2: two-dimensional complex sequence algorithm ranks

资源描述基于人工神经网络方法建立了ＲFID 反射信号强度分布模型． 该方法仅依赖数据，实施简 单． 为克服传统BP 算法对初值敏感、易陷入局部极值的缺陷，引入一种连续的蚁群优化算法来 确定多层神经网络的权值，该算法具有更强的全局搜索能力和效率． 讨论了算法的基本理论和具 体步骤，最后利用实际ＲFID 设备采集的反射信号强度数据对算法进行测试，对理论信号模型和 实际的建模结果进行了比较，并分析了算法的逼近能力和泛化能力． 结果表明在考虑到不可避免 的误差和扰动下，所提出的方法可以更好地建模ＲFID 信号强度的实际分布，具有良好的性能．

快速排序和冒泡排序-rapid sequencing and Bubble Sort

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
