Acta Metallurgica Sinica(English Letters) 2017年第10期30卷 999-1007页

作者： Li-Juan Qin yuan-Chao huang Laboratory for Corrosion and Protection Institute of Metal ResearchChinese Academy of Sciences College of Material Science and Engineering University of Science and Technology of China

The effects of single surfactant hexadecylpyridinium bromide（HPB） and cetyltrimethylammonium bromide（CTAB） and the combination of HPB and CTAB on the Cr nanoparticle content in the Ni-Cr film prepared by codeposition were investigated. Single HPB/CTAB addition inhibited the oxidation and amorphous transformation of the Cr nanoparticles in the plating bath and effectively stabilized the Cr nanoparticles content at approximately 10 mass% as a function of time. Moreover, the combination of HPB and CTAB formed a cylindrical micelle structure on the Cr nanoparticle surface, which prompted the formation of a layer of NiCr2O4. As a result, the Cr nanoparticle content increased sharply to 20 mass%.

The complete mitogenome of the Chinese bush cricket,Gampsocleis gratiosa(Orthoptera:Tettigonioidea)

引用

Journal of Genetics and Genomics 2008年第6期35卷 341-348页

作者： Zhijun Zhou Fuming Shi yuan huang College of Life Science Shaanxi Normal University Xi＇an 710062 China College of Life Science Hebei University Baoding 071002 China

The complete mitochondrial genome （mitogenome） of Gampsocleis gratiosa was determined. The 15,929 bp in the size of G. gratiosa mitogenome contains a typical gene content, base composition, and codon usage found in metazoan. All 13 protein coding genes （PCGs） of the G gratiosa mitogenome start with a typical ATN codon. The usual termination codons （TAA and TAG） were found from 10 PCGs. However, the atp6, had4, and had5 had incomplete termination codon （T）. The anticodons of all tRNAs are identical to those observed in Drosophila yakuba and Locusta migratoria, and can be folded in the form of a typical clover leaf structure except for trnS （AGN）. The secondary structure of trnS （AGN） was drawn according with the Steinberg-Cedergren tertiary structure. The A＋T content （67.4%） of the A＋T-rich region is relatively lower among the mitogenome regions, in contrast, it usually contains the highest A＋T content for most insects. Two isolated sequence repeat regions （202 bp） were found in the A＋T-rich region with mapping and secondary structure information.

A Robust Face Recognition Method Combining LBP with Multi-mirror Symmetry for Images with Various Face Interferences

引用

International Journal of Automation and computing 2019年第5期16卷 671-682页

作者： Shui-Guang Tong yuan-yuan huang Zhe-Ming Tong State Key Laboratory of Fluid Power and Mechatronic Systems Zhejiang UniversityNo.38Zheda RoadHangzhou 310027China School of Mechanical Engineering Zhejiang UniversityNo.38Zheda RoadHangzhou 310027China

Face recognition(FR) is a practical application of pattern recognition(PR) and remains a compelling topic in the study of computer vision. However, in real-world FR systems, interferences in images, including illumination condition, occlusion, facial expression and pose variation, make the recognition task challenging. This study explored the impact of those interferences on FR performance and attempted to alleviate it by taking face symmetry into account. A novel and robust FR method was proposed by combining multi-mirror symmetry with local binary pattern(LBP), namely multi-mirror local binary pattern(MMLBP). To enhance FR performance with various interferences, the MMLBP can 1) adaptively compensate lighting under heterogeneous lighting conditions, and 2) generate extracted image features that are much closer to those under well-controlled conditions(i.e., frontal facial images without expression). Therefore, in contrast with the later variations of LBP, the symmetrical singular value decomposition representation(SSVDR) algorithm utilizing the facial symmetry and a state-of-art non-LBP method, the MMLBP method is shown to successfully handle various image interferences that are common in FR applications without preprocessing operation and a large number of training images. The proposed method was validated with four public data sets. According to our analysis, the MMLBP method was demonstrated to achieve robust performance regardless of image interferences.

作者： yuan-yuan huang Chang-He Liu You-Lin Shang School of Mathematics and Statistics Henan University of Science and TechnologyLuoyang 471023HenanChina

The Douglas–Peaceman–Rachford–Varga operator splitting methods are a class ofefficient methods for finding a zero of the sum of two maximal monotone operatorsin a real Hilbert space;however, they are sometimes difficult or even impossible tosolve the subproblems exactly. In this paper, we suggest an inexact version in whichsome relative error criterion is discussed. The corresponding convergence propertiesare established, and some preliminary numerical experiments are reported to illustrateits efficiency.

Designing a location update strategy for free-moving and network-constrained objects with varying velocity

引用

Journal of Zhejiang University-Science C(Computers and Electronics) 2014年第8期15卷 675-686页

作者： yuan-Ko huang Lien-Fa LIN Department of Information Communication Kao-Yuan University

Spatio-temporal databases aim at appropriately managing moving objects so as to support various types of queries. While much research has been conducted on developing query processing techniques, less effort has been made to address the issue of when and how to update location information of moving objects. Previous work shifts the workload of processing updates to each object which usually has limited CPU and battery capacities. This results in a tremendous processing overhead for each moving object. In this paper, we focus on designing efficient update strategies for two important types of moving objects, free-moving objects(FMOs) and network-constrained objects(NCOs), which are classified based on object movement models. For FMOs, we develop a novel update strategy, namely the FMO update strategy(FMOUS), to explicitly indicate a time point at which the object needs to update location information. As each object knows in advance when to update(meaning that it does not have to continuously check), the processing overhead can be greatly reduced. In addition, the FMO update procedure(FMOUP) is designed to efficiently process the updates issued from moving objects. Similarly, for NCOs, we propose the NCO update strategy(NCOUS) and the NCO update procedure(NCOUP) to inform each object when and how to update location information. Extensive experiments are conducted to demonstrate the effectiveness and efficiency of the proposed update strategies.
