Reasoning with Ontology Model Based on Jena  [PDF]
Jing WU, Yongxin HUANG
Intelligent Information Management (IIM) , 2009, DOI: 10.4236/iim.2009.11005
Abstract: As the core of knowledge representation, reasoning plays an important role in the Semantic Web. In this paper, introduce Description Logic as the theoretical foundation of reasoning in the Semantic Web and OWL which needs to be expressive enough for representing knowledge and computationally tractable for inference of large-scale applications. Then construct an ontology model depicted with OWL by protégé and Jena API , and also prove the validity of reasoning with the model.
Genre-Based Analysis of American Tourism Brochure  [PDF]
Jing Luo, Tingyu Huang
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.39028
Abstract: The language in tourism brochure can help to construct destination’s image in reader’s mind. In this paper, 35 tourism brochures collected from more than 20 renowned attractions in western America have been selected as the corpus. On basis of English for Special Purpose School’s genre analysis theory, this article makes an attempt to generalize a specific generic structure for tourism brochure with eight moves by utilizing Bhatia’s move-structural model in advertisement as the theoretical framework. In addition, an innovative cross-disciplinary trial has been made to combine genre analysis with the formation process of tourist destination image. Moves and strategies with the communicative purpose of shaping destination image are thereby emphasized. Through organizing the generic feature of American tourism brochure, enlightenment of typical strategies in the discourse production for domestic tourism brochure will be concluded.
Statistical Transform of Signal Field with ASE Noise through a Fiber Amplifier  [PDF]
Jing Huang, Jianquan Yao
Optics and Photonics Journal (OPJ) , 2016, DOI: 10.4236/opj.2016.68B012
Abstract:
While the signal field + ASE noise pass through a span of transmission fiber, a dispersion compensation grating and a fiber amplifier(with the generation of ASE noise), the nonlinear Fokker-Plank equations, describing the probability transforms of the field, are established and solved. Based on these statistical theories, the probability distributions of the signal + ASE noise field through 50km NZDSF, a dispersion compensation grating and a fiber amplifier link, are obtained. The dispersion and nonlinear effects in transmission fiber induce frequency offsets in the probability distribution of field and they cannot be dissipated by dispersion compensation. The generation of ASE noise in the amplifier will accelerate this frequency offset.
Statistical Analyses of ASE Noise  [PDF]
Mingxiang Gui, Huang Jing
Optics and Photonics Journal (OPJ) , 2017, DOI: 10.4236/opj.2017.710016
Abstract: The evolution of ASE noise and the generation of nonlinear phase shift are analyzed based on the travelling wave solution of ASE noise and its probability density function by solving the Fokker-Planck equation including dispersion effect. Nonlinear effect has strong impact on ASE noise. After the transmission in non-zero dispersion shift fibers + dispersion compensation fibers, due to the nonlinear effect, ASE noise is enhanced. Detailedly, the real part of ASE decreases but the image part increases greatly compared to that with dispersion effect only. Nonlinear phase shift, related to the image part of ASE noise, occurs in this kind of link. The impact of signal intensity on ASE noise induces fluctuations to the both curves of ASE noise and nonlinear phase shift as functions of time, respectively. Furthermore, it results in the non-Gaussian distribution of ASE noise probability density function (side-bands occurring) and brings more than 1 dB additive BER.

Hausdorff theory of dual approximation on planar curves
Jing-Jing Huang
Mathematics , 2014,
Abstract: Ten years ago, Beresnevich-Dickinson-Velani initiated a project that develops the general Hausdorff measure theory of dual approximation on non-degenerate manifolds. In particular, they established the divergence part of the theory based on their general ubiquity framework. However, the convergence counterpart of the project remains wide open and represents a major challenging question in the subject. Until recently, it was not even known for any single non-degenerate manifold. In this paper, we settle this problem for all curves in $\mathbb{R}^2$, which represents the first complete theory of its kind for a general class of manifolds.
Rational points near planar curves and Diophantine approximation
Jing-Jing Huang
Mathematics , 2014,
Abstract: In this paper, we establish asymptotic formulae with optimal errors for the number of rational points that are close to a planar curve, which unify and extend the results of Beresnevich-Dickinson-Velani and Vaughan-Velani. Furthermore, we complete the Lebesgue theory of Diophantine approximation on weakly non-degenerate planar curves that was initially developed by Beresnevich-Zorin in the divergence case.
A Research on Quality Assurance in Arts Classroom Teaching in Higher Education in China  [PDF]
Ping Huang, Jing Chen, Wenjing Zheng
Open Journal of Social Sciences (JSS) , 2013, DOI: 10.4236/jss.2013.11002
Abstract: Classroom teaching is one of the most important aspects and links to assure quality in higher education. Although there have been some theoretical discussions and research by Chinese scholars about how to enhance the quality of classroom teaching in higher education, the experimental research of quality assurance in teaching is rarely seen. Based on an exploration of the teaching-learning methods of the presentation model, this article will provide evidence that interactive teaching styles, especially Presentation Teaching Methods, are very efficient in improving the quality of arts classroom teaching in higher education. It will analyze the quality and quantity of the empirical knowledge, which includes consciously challenging authority, academic research competencies of critical reading, critical writing and some practical abilities in finding, analyzing, solving problems and team work. Finally, it will provide some suggestions for quality assurance in classroom teaching in higher education.
Robust Palmprint Recognition Base on Touch-Less Color Palmprint Images Acquired  [PDF]
Haifeng Sang, Yueshi Ma, Jing Huang
Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.42019
Abstract:

In order to make the environment of palmprint recognition more flexible and improve the accuracy of touchless palmprint recognition. This paper proposes a robust, touchless, palmprint recognition system which is based on color palmprint images. This system uses skin-color thresholding and hand valley detection algorithm for extracting palmprint. Then, the local binary pattern (LBP) is applied to the palmprint in order to extract the palmprint features. Finally, chi square statistic is used for classification. The experimental results present the equal error rate of 3.7668% and correct recognition rate of 97.0142%. Therefore the results show that this approach is robust and efficient in color palmprint images which are acquired in lighting changes and cluttered background for touch-less palmprint recognition system.

Jing Huang, Bing Shen, Feng Yang
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.24072
Abstract: A simulation model of shipboard low voltage molded case circuit breaker (MCCB) is developed based on power system simulation software PSCAD/EMTDC. The motion characteristic of the magnetic instantaneous acting trip based on electromagnetic characteristic analysis and Cassie arc model are applied into the simulation model to describe the dynamic behavior of the MCCB
during short-circuit protection. The results of short-circuit interruption experiments verify the simulation model. It demonstrates that the simulation model has good prospect in optimizing the design and protection performance of MCCB.
