This paper proposes a new pitch detection method with the combination of morphology filter and wavelet transform. Before detection, a pre-process based on morphology filter is performed to remove the noise. Then the pitch is detected by wavelet transform. Experiments show that this method can realize pitch period calculation accurately and has a better robustness.

An effective approach to evaluate Internet topology model was mainly studied in this paper. SLS (Signless Laplacian Spectra), is used to quantitatively identify the topology properties of the Internet generated by the model and the Internet out of real measuring. SLS eigenvectors could be gained out of this procedure, then a cross-correlation algorithm was performed on the eigenvectors to give the difference identification in a quantitative way. With this, a specific way of using the estimation approach within a Genetic Algorithm was finally given.

A novel detection method based on digital speckle correlation is proposed for the tensile test of sheet metal. Standardized covariance correlation formula is adapted according to the specimen’s tensile deformation. Also a new calibration method employing specimen as the calibrate object is presented combination with edge detection techniques. Purposing to improve the accuracy and rates of correlation search, the edge tracking measure results are adopted as the initial value of correlation search. And the feasibility of this set of method is proved by silica gel tensile tests.

Resource space model (RSM) is a semantic data model to manage and share heterogeneous resources by appropriately classifying the contents of resources in the future interconnection environment. The current storage model C-tree for RSM is too complicated to develop an available sharing tool which affects the study of RSM. For simplifying and improving the Storage efficiency of RSM, this paper presents a simple storage mechanism for RSM based on container. The approach maps RSM into Object Model which use container for storing Resource Space Entities and consider the SELECT and INSERT operations as behaviors in Class. Moreover, the most advantageous features of RSM, aggregation query, can be achieved through the SELECT operation. And our work can also be used in the nested table application of RSM.
资源空间模型(Resource space model, RSM)是在未来互联环境中，通过对资源内容进行适当分类，实现异构资源管理和共享的语义数据模型。现有的RSM存储模型C-tree过于复杂，无法开发出可用的共享工具，影响了RSM的研究。为了简化和提高RSM的存储效率，本文提出了一种基于容器的RSM存储机制。该方法将RSM映射到对象模型中，对象模型使用容器存储资源空间实体，并将SELECT和INSERT操作视为类中的行为。此外，RSM最有利的特性聚合查询可以通过SELECT操作来实现。我们的工作也可以用于RSM的嵌套表应用程序。

A novel modular multiplier is implemented on FPGA for elliptic curve cryptography (ECC) over GF(p). First, using the embedded 18×18-bit multipliers in the FPGA device, we design a 256-bit Montgomery modular multiplier which spends 3 clock cycles to compute a modular multiplication. Second, the algorithm for Karatusba-Ofman multiplication is used to reduce the number of embedded multipliers needed. Third, to get a higher throughput rate on FPGA devices, we propose a 5-stage pipeline structure to realize the modular multiplier. At last, implemented on Altera Cyclone3 EP3C40F324C6, this modular multiplier runs at the clock rate of 30.38MHz, and performs a 256-bit Montgomery modular multiplication in 0.1µs, which is much faster than previous implementations on FPGA device.
