β-Hausdorff Operator on Lipschitz Space in the Unit Polydisk  [PDF]
Rong Hu, Chaofeng Zhang
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.45022

In this paper, we define β-Hausdorff operator on the unit polydisk and study the boundedness of the operator on Lipschitz space. Firstly, we translate the problem of coefficient into integral of weighted composition operator, then give the sufficient conditions of boundedness, and also obtain an upper bound for the operator norm on Lipschitz space.

An Empirical Study on Fuzzy Comprehensive Evaluation of Red Tourism Resources Based on AHP  [PDF]
Rong Hu, Chaofeng Zhang
Applied Mathematics (AM) , 2018, DOI: 10.4236/am.2018.92012
Red tourism, which is featured with spiritual culture, resource fusion and historical socialization, is a remarkable innovation with Chinese characteristics. It is the shinning point of China’s tourism business development. This paper will show the objective and correct evaluation of red tourism resource. Firstly, it will create evaluation index system by theoretical analysis method and expert consultation method. Secondly, it will evaluate each object synthetically by fuzzy comprehensive evaluation method and analytic hierarchy process. Finally, through case study of General Zhang Aiping’s, Former Residence in Dazhou, Sichuan Province, conclusion and related suggestion will be achieved.
The Evaluation of Teaching Level and Exploration of Improving Ability for Young Teachers in Higher Education  [PDF]
Zhang Liu, Fang Mei, Juhua Hu, Jiangen Hu
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.610099
Abstract: By analyzing the final results sample of teaching competition of the first young college teachers in Jiangxi Province in 2014, we give a comprehensive evaluation for the subject composition and the title of young teachers in higher education, which can provide a reference and basis for the university managers to adopt more scientific teaching methods and means to improve the quality of higher education. Meanwhile, for the lack of teaching experiences’ young teachers, we bring out effective ways to improve the teaching level from curriculum, instructional design, classroom teaching and teaching reflection.
Lex et Scientia , 2009,
Abstract: This paper is an attempt to explore the determinants behind various group formations. We show that the group formation depends on the efficiency of information transmission. In our point of view, the optimal grouping structure should minimize the distortion induced by the informative imperfection so that it is easiest to sustain the cooperative equilibrium.
Classification of Power Quality Disturbances Using Wavelet Packet Energy Entropy and LS-SVM  [PDF]
Ming Zhang, Kaicheng Li, Yisheng Hu
Energy and Power Engineering (EPE) , 2010, DOI: 10.4236/epe.2010.23023
Abstract: The power quality (PQ) signals are traditionally analyzed in the time-domain by skilled engineers. However, PQ disturbances may not always be obvious in the original time-domain signal. Fourier analysis transforms signals into frequency domain, but has the disadvantage that time characteristics will become unobvious. Wavelet analysis, which provides both time and frequency information, can overcome this limitation. In this paper, there were two stages in analyzing PQ signals: feature extraction and disturbances classification. To extract features from PQ signals, wavelet packet transform (WPT) was first applied and feature vectors were constructed from wavelet packet log-energy entropy of different nodes. Least square support vector machines (LS-SVM) was applied to these feature vectors to classify PQ disturbances. Simulation results show that the proposed method possesses high recognition rate, so it is suitable to the monitoring and classifying system for PQ disturbances.
A Study on the Control Technique of Construction Project Process  [PDF]
Changming Hu, Shaoping Zhang, Xueyan Wang
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.53041
The construction process control of large-scale projects is one of the difficulties and keys in the owner’s project management. Based on generalization process index, this paper proposes an approach to construction project process control. The paper elaborates on the concept and calculation of generalization process index, which, on analysis, possesses Markov property. Monthly generalization process index is regarded as a state of Markov chain, and the transition between different states is realized by computer simulation. According to the Markov process forecasting model and by means of MATLAB program, the project process forecast is realized, and the completion probability in contract period is obtained. From practical instances, it is concluded that this approach has good applicability and operability and that the obtained results can reflect the degree of project risks.
Quantum Walk of Two Quantum Particles on One Dimensional System  [PDF]
Yongmei Zhang, Junjie Xiao, Dongsheng Hu
Journal of Quantum Information Science (JQIS) , 2013, DOI: 10.4236/jqis.2013.34018

We study two particle quantum walks on one dimensional chain. Probability distribution of two particle quantum walks is dependent on the initial state, and symmetric quantum walk or asymmetric quantum walk is analogous to that of one particle quantum walk. The quantum correlation probability is much different from classical coincidence probability. The difference reflects quantum interference between two particles.

Research on the Ecological Conflict between Coastal Wetland and Port Construction—A Case Study of the Meizhou Gulf  [PDF]
Jun Hu, Mu Zhang, Xiang Huang
Low Carbon Economy (LCE) , 2014, DOI: 10.4236/lce.2014.52007
Abstract: This article is a study on the management of wetland. The future impact of landscape of coastal wetland with the constant changes of human activities is discussed on the basis of the theory and methodology of landscape ecology. Solutions to the contradictions of ecological protection and port construction are put forward.
New Exact Explicit Solutions of the Generalized Zakharov Equation via the First Integral Method  [PDF]
Yuhuai Sun, Hanlei Hu, Jian Zhang
Open Journal of Applied Sciences (OJAppS) , 2014, DOI: 10.4236/ojapps.2014.45025
Abstract: The generalized Zakharov equation is a coupled equation which is a classic nonlinear mathematic model in plasma. A series of new exact explicit solutions of the system are obtained, by means of the first integral method, in the form of trigonometric and exponential functions. The results show the first integral method is an efficient way to solve the coupled nonlinear equations and get rich explicit analytical solutions.
The Current Opinions of Capillary Leak Syndrome  [PDF]
Jun Su, Ying Zhang, Wei Hu
Open Journal of Clinical Diagnostics (OJCD) , 2015, DOI: 10.4236/ojcd.2015.51003
Abstract: Capillary Leak Syndrome (CLS) in patients with severe course of disease is more and more common, and the clinical manifestations of CLS include systemic edema, hypoproteinemia, effective circulating blood volume reduction and hemoconcentration. The common pathogenies are sepsis, severe trauma, cardiopulmonary bypass and so on. Clinically, CLS is usually divided into leakage period and recovery period, with different pathophysiologic process, clinical manifestation and treatment in different period respectively. Although there are more treatments, they are not effective treatment measures. There have been so many studies about improvement of endothelial function, macromolecular colloid liquid applications, and continuous blood purification treatment. Systematic understanding of the pathological mechanism, clinical manifestations and staging, diagnosis and treatment of the CLS has a guiding value.
