The Over-the-Horizon Radar (OTHR) is an effective approach for long-range target detection. However, most existing OTHR systems resort to receive array with quite large aperture, which makes them difficult to deploy. Based on the small aperture receive array, this paper presents a new architecture of long-range target detection system. The shortage of small aperture receive array on echo signal-to-noise...
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...
Curved artificial compound eyes (CACEs) are fabricated using microscale replication, stamping, and casting processes to form deposited 2-D microlens-pattern composite films into 3-D structures. The films are made up of polydimethylsiloxane (PDMS)–Parylene-C–PDMS layers. The layers are used for pattern replication, isolation, and buffering, respectively. The effect of the buffer layer on the ultimate...
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...
The storage architecture, data layout and access control strategies of the large-scale video storage server have great effects on its performance. In this paper, it analyses the performance requirement, architecture, data layout, access controlling and etc. of the large-scale video storage server and proposes a multi-segment video storage strategy of MPEG coding, which is based on the parallel disk...
