Abstract:FP-growth algorithm for mining association rules is divided into two phases: building a FP-tree and mining frequent patterns. In this paper new algorithms are proposed to improve the two stages separately. In the first stage, if frequent items in header table have the same support, their position can be dynamically changed to construct a compressed and optimized FP-tree. IMFP-tree algorithm is proposed to realize that function. In the second stage, CFP-mine algorithm is proposed, which constructs pattern-base by using a new method different from the conditional pattern-base in FP-growth.This paper mines frequent itemsets with a new combination method without recursive construction of conditional FP-tree. It has theoretically proved and experimentally verified the correctness and efficiency of CFP-mine algorithm.

Abstract:In fast handoff process of WLAN，this paper presents a method to choose goals for keeping the load balancing. The method combines the AP size of spare bandwidth, the signal intensity and the current load ratio of the AP. To all possible adjacency APs, if the AP free bandwidth is less than the bandwidth needed by the mobile terminal, the APs should not be considered. Otherwise, the function is calculated and the AP is chosen with the maximal function value to connect by using the load ratio of adjacency AP and RSSI of the terminal. Simulation results show that the method is better than other methods in the overall performance. They don’t present that a certain AP is overloaded.

Thus, this paper proposes a heuristic algorithm based on the directive expansion of inter-relevance. Experimental results show that this algorithm can be quicker and more effective than the existing heuristic algorithm in finding better combinations of the candidate instructions.

The other region is covered with big pieces, by utilizing the image fusion technology to flat the place of splicing naturally. Owing to coalesce the above two algorithms, the speed of this algorithm has preponderated over Xu’s greatly.

Abstract:Efficient trend extraction methods can provide early warnings, severity assessments of monitored subjects and information for decision support. The traditional algorithms for trend analysis of curves include Sliding Window algorithm (SW) and Extrapolation for On-line Segmentation of Data algorithm (OSD), which use total least squares for curve fitting. Compared with conventional least squares, the total least squares has a higher accuracy of fitting a straight line. In addition, since there is no restriction on the maximum length of the sliding window for SW algorithm, the length of window can be very long when threshold for Detection of point becomes larger. As OSD algorithm restricts the minimum length of sliding window, mutations within minimum sliding window cannot be detected for defects of the SW algorithm and the OSD algorithm. This paper presents a new method for trend analysis of data streams. The method uses total least squares to improve the accuracy of trend analysis. It also presents variable sliding window algorithm to solve the fixed window problem with the SW algorithm and OSD algorithm to achieve a reasonable segmentation for data streams. The experimental results show that the method is effective.

Abstract:In most cases, compared to computing time, memory access time takes a much larger proportion of program running time. Therefore, memory access approach can affect the program performance significantly. Testing results show that the performance of ATLAS transplanted on KD-50-I, which is based on Loongson 2F,reaches only 30% of its theoretical peak. In this paper, by exploiting Loop Unrolling technique to decrease memory access frequency, enhancing time and space locality to reduce cache misses and nonblocking cache mechanism to form memory access pipeline, the performance of optimized ATLAS can be improved to 50% higher.

Abstract:With the progress of researches on the integration of Geographic Information System (GIS) and Remote Sensing (RS), digital earth, and information sharing, it has become significant to publish RS images on the Internet. A large image is often extract ed into different levels of detail and cut into pieces or tiles to construct a pyramid structure for Web distribution. Therefore, an efficient and flexible cutting algorithm of RS images under the Internet environment is correspondingly expected. In this paper, methods to achieve programming by combining Java with C++ are discussed. The JNI-based combined programming is discussed in four sections, including parameter trans fer, call C++ functions in Java, call Java functions in C++, and exception handling. Subsequently, the Web-oriented cutting algorithm of RS images is implemented based on the above combined programming, which makes the rapid Web publication of RS images become easier to accomplish. Tests of the program with a global RS image prove that the design scheme is feasible and the algorithm is effi cient, stable, and flexible.
