Accurate and efficient power grid analysis has become increasingly important in semiconductors chip design and verification. It is one of the most computationally challenging tasks in high performance processor design analysis. Due to the extremely large memory required to store and manipulate the design data, it is no longer possible to accommodate the analysis using one or more serial processes...
Over the last few decades, feature selection has been a hot research area in pattern recognition and machine learning, and many famous feature selection algorithms have been proposed. Among them, feature selection using positive approximation(FSPA) is an accelerator for traditional rough set based feature selection algorithms, which can significantly reduce the running time. However, FSPA still cannot...
Searching frequent patterns in transactional databases is considered as one of the most important data mining problems and Apriori is one of the typical algorithms for this task. Developing fast and efficient algorithms that can handle large volumes of data becomes a challenging task due to the large databases. In this paper, we implement a parallel Apriori algorithm based on MapReduce, which is a...
Distributed and Parallel algorithms have attracted a vast amount of interest and research in recent decades, to handle large-scale data set in real-world applications. In this paper, we focus on a parallel implementation of KD-Tree based outlier detection method to deal with large-scale data set. As one of the state-of-the-art outlier detection methods, KD-Tree based has been approved to be an effective...
A portable Sequence of Events (SOE) tester is designed and studied by the paper, which is made up of host and slave computers. CPU is C8051F121 chip whose frequency is 100MHz. Host and slave computers translate data through RS-485 bus. Touching-screen is used to operation and display. Minimal triggering interval time of SOE tester is 0.1ms. There are many Analog-triggering channels in SOE tester that...
In this paper, an automatic control system based on industrial control computers (IPC) and a programmable logic controller is designed by using field bus, PLC and configuration techniques to solve the automatic control problem of coal preparation process. The cross complex process control and fault processing are implanted by PLC, and configuration program provides friendly interface to user. Compared...
In this paper, we present a symmetrical invariant LBP (SILBP) texture descriptor based on the texture pattern equivalent, which is defined according to visual perception of textures. Then we extend the SILBP to linear SILBP. Our experiments on image retrieval show that the proposed texture discriptor has the advantages of symmetrical invariant, rotation robustness and computing simplicity.
