Google's Android Native Development Kit (NDK) is a toolset that lets you embed components to use of native code in your Android applications. It makes possible for developers to easily compile in C/C++ for the Android development platform. Generally, developer does not concern how effective between native code and Dalvik Java code that will causes poor performance of Android. There are some researches discussed about benchmark Java and C/C++. But they do not consider the issues of Dalvik and native code for Android programming or evaluate them in real Android device. In this work, we use a more complete approach to benchmark Dalvik java code and Native code on real Android device. We conducted 12 test programs to analyze the performance and found that native code faster than Dalvik Java code for about 34.2%.
b谷歌的Android Native Development Kit (NDK)是一个工具集，可以让你在Android应用程序中嵌入组件以使用本地代码。它使开发人员可以轻松地在Android开发平台上用C/ c++进行编译。一般来说，开发者并不关心原生代码和Dalvik Java代码之间的效率如何，这会导致Android的性能不佳。对Java和C/ c++的基准测试进行了一些研究。但他们没有考虑Dalvik和Android编程的本地代码问题，也没有在真实的Android设备中进行评估。在这项工作中，我们使用更完整的方法在真实的Android设备上对Dalvik java代码和Native代码进行基准测试。我们进行了12个测试程序来分析性能，发现本机代码比Dalvik Java代码快34.2%左右。

A novel Internet media distribution system based on overlay multicast was studied and implemented. In the system, the nodes build the multicast route with a tree-first strategy and maintain the topology with an active strategy. In order to run the routing and topology algorithm effectively, a series of messages and protocols are designed as the core in the system. The implementation of the multicast system is object-oriented and modular. The experiments on Planet Lab in which the end hosts are all over the world have shown that, the system can construct and maintain the overlay multicast tree efficiently, and can also distribute the real-time streaming audio with high scalability.

A novel subspace learning algorithm named neighborhood discriminant nearest feature line analysis (NDNFLA) is proposed in this paper. NDNFLA aims to find the discriminant feature of samples by maximizing the between-class feature line (FL) distances and minimizing the within-class FL distance. At the same time, theneighborhood is preserved in the feature space. Experimental results demonstrate the efficiency of the proposed algorithm.

Among bit plane coding field, coding of significance layer is an important topic. According to the advantage of quad-tree representation on codeword reduction for large zero blocks, zero block coding is a potential method in significance coding. However, traditional embedded zero block coding method exhibits repeated node visits in recursive procedure calling. In this paper, a top-to-button significance coding methodology is proposed to reduce the repeated node visiting. On the other hand, the produced coefficients are reduced at the same time. According to the experiment results, the visited node count and transmitted codeword of proposed work is smaller than original embedded zero block coding and the significance layer in Wavelet transformed coefficients of JPEG 2000. Besides, the reduction of node visiting count increases the significant bit updating efficiency. The results prove the efficiency and the effectiveness of codeword reduction of proposed work.

In the past, pre-large fast-updated sequential pattern trees (pre-large FUSP tree) were proposed for efficiently mining large sequences for record insertion and deletion, respectively. In this paper, we thus proposed a maintenance approach for efficiently maintaining pre-large FUSP trees and effectively deriving desired large sequences when data in databases are modified. Experimental results also show that the proposed algorithm has a better performance in execution time.

Sparse arrays are popular in sonar, ultrasonic imaging and other acoustic equipment. For inter-element spacing larger than one wave length, there will be grate lobes for ordinary sparse array. Using genetic algorithm to optimize array with randomly spaced elements to suppress the grate lobes is introduced in this paper. Fitness function design and variable choosing method for genetic algorithms application in this kind of objects are presented. A single object fitness function instead of multi objects fitness function usually used for array design is proposed.
