Network community structure is one of the most fundamental and important topological properties of complex networks, within which the links between nodes are very dense, but between which they are quite sparse.

网络簇结构是复杂网络最普遍和最重要的拓扑属性之一，具有同簇节点相互连接密集、异簇节点相互连接稀疏的特点。

the fast transposition algorithm to sparse matrix expressed by triple list is introduced.this algorithm needs to determine the position in the transposed matrix position of the first element which is not equal to zero in the original matrix each row,it uses two arrays as auxiliary space.in order to reduce the auxiliary space which the algorithm needed,an improvement is made through introducing two simple variables.the improved algorithm saves a half auxiliary space compared to the original algorithm at the same time complexity.

摘 要：介绍基于三元组表表示的稀疏矩阵的快速转置算法，此算法在转置前需要先确定原矩阵中各列第一个非零元在转置矩阵中的位置，在此使用2个数组作为辅助空间，为了减少算法所需的辅助空间，通过引入2个简单变量提出一种改进算法。该改进算法在时间复杂度保持不变的情况下，空间复杂度比原算法节省一半。

Based on trigram models, this paper proposes a three-step method of "word—similar word—part of speech" by incorporating the similar words and solves the problem of sparse data to a large extent.

本文利用三元模型，通过引入相似词，采取"词形-相似词-词性"三步回退的策略，比较好地缓解了数据稀疏问题。

There maybe be some differences between the original assumption PDF to the new one generated by sparse data input and we suggested to using the truncated probability distribution function for modeling this situation.

针对此分布不匹配的问题，本研究首先提出使用截尾分布机率密度函数(truncated probability distribution function)的概念来近似。

In mobile Ad Hoc networks, geographical routing protocol was a kind of important routing protocols, which requires the underlying topology be planar, sparse, connected and t-spanner in order to guarantee the delivery of message and bound the routing length. A new topology control algorithm named ODT, which constructed the geometry structure named ODT graph, was proposed.

基于移动Ad Hoc网络的特性，提出了一种适用于移动Ad Hoc网络的路由协议PAGPSR(Power-Aware Greedy Perimeter Stateless Routing)，该协议在原有的基于地理位置的路由协议GPSR的基础上增加了节点能量感知和负载均衡算法，修改了GPSR的转发策略，使网络中能量消耗和网络负荷分布更加均匀，从而延长了整个网络的生存时间。

The matrix multiplier adopted in FPGA computation unit is optimized for sparse matrix multiplication.

计算单元中采用的矩阵乘法器针对稀疏矩阵乘法进行了优化，能够避免零元素块参与计算而提高系统性能。
