Research on Interactive Design of Three-Way Interactive Platform in Scenic Spots—Based on the Theory of User Experience Elements: A Case Study of Danxia Mountain Scenic Area  [PDF]
Yirun Chen, Junyong Lai, Mu Zhang
Journal of Service Science and Management (JSSM) , 2019, DOI: 10.4236/jssm.2019.123022
Abstract: In recent years, due to the promotion of government policies and the continuous development of tourism information, various tourism application platforms have emerged. At the same time, the sustainable development of “the scenic spot” requires the concerted efforts of tourists, residents and the spots themselves. However, there is no application platform to integrate the three resources in the market, and related tourism applications have problems such as poor user experience and serious homogenization. Therefore, the development of a three-way interactive platform with excellent user experience is a new direction for tourism application research. Based on the theory of user experience elements, this paper analyzes the key points and relationships in the interaction design of user experience elements based on five levels. Using Danxia Mountain Scenic Area as an example, the analysis and design of the three-way interactive platform in the scenic spot were completed according to the theory of user experience elements, and the feasibility of the method was demonstrated.
The Influencing Factors and Mechanism of Tourists’ Revisit Intention in Chinese Tourism Characteristic Towns—Take Gankeng Hakka Town in Shenzhen as an Example  [PDF]
Mu Zhang, Qing Chen, Wenyu Li
Journal of Service Science and Management (JSSM) , 2019, DOI: 10.4236/jssm.2019.123023
Abstract: Tourists’ revisit intention is of great significance to the sustainable development of Chinese tourism characteristic towns. This study took Gankeng Hakka Town which is a typical Chinese tourism characteristic town as an example, using confirmatory factor analysis (CFA) method of Structural Equation Modeling (SEM) to build a structural equation model regarding tourists’ revisit intention. This model included ten paths and four variables which were tourist satisfaction, tourist motivation, tourists’ perceived value and tourists’ revisit intention. Through CFA, this paper found out the dimensions of the three variables (tourist satisfaction, tourist motivation, tourists’ perceived value), also tested the reliability and validity of the measurement items. Through SEM, CMIN/DF, RMR, RMSEA, GFI, AGFI, NFI, RFI, IFI, TLI, CFI, PGFI, PCFI and PNFI were selected to evaluate the degree of finesse between the model and the data. The results indicate that the tourist satisfaction has a direct and significant effect on the tourists’ revisit intention; tourist motivation and tourists’ perceived value have no direct influence on tourists’ revisiting intention, but they can influence the revisiting intention through the influence of tourist satisfaction. Therefore, tourist satisfaction has a mediating effect in the mechanism of the entire model. Among them, the factors of “Increase Knowledge”, “Rich Atmosphere” and “Satisfactory Landscape” have great influence on tourists’ revisit intention. It is suggested that the construction of Chinese tourism characteristic towns should focus on the development of scenic cultural atmosphere and park landscape in the future.
The roles of spatial locations and patterns of initial errors in the uncertainties of tropical cyclone forecasts

Boyu Chen,Mu Mu,

大气科学进展 , 2012,
Abstract: In this study, a series of sensitivity experiments were performed for two tropical cyclones (TCs), TC Longwang (2005) and TC Sinlaku (2008), to explore the roles of locations and patterns of initial errors in uncertainties of TC forecasts. Specifically, three types of initial errors were generated and three types of sensitive areas were determined using conditional nonlinear optimal perturbation (CNOP), first singular vector (FSV), and composite singular vector (CSV) methods. Additionally, random initial errors in randomly selected areas were considered. Based on these four types of initial errors and areas, we designed and performed 16 experiments to investigate the impacts of locations and patterns of initial errors on the nonlinear developments of the errors, and to determine which type of initial errors and areas has the greatest impact on TC forecasts.
Models of Neutrino Masses and Mixing
Chen, Mu-Chun
High Energy Physics - Phenomenology , 2007, DOI: 10.1063/1.2775909
Abstract: Neutrino physics has entered an era of precision measurements. With these precise measurements, we may be able to distinguish different models that have been constructed to explain the small neutrino masses and the large mixing among them. In this talk, I review some of the existing theoretical models and their predictions for neutrino oscillations.
TASI 2006 Lectures on Leptogenesis
Chen, Mu-Chun
High Energy Physics - Phenomenology , 2007,
Abstract: The origin of the asymmetry between matter and anti-matter of the Universe has been one of the great challenges in particle physics and cosmology. Leptogenesis as a mechanism for generating the cosmological baryon asymmetry of the Universe has gained significant interests ever since the advent of the evidence of non-zero neutrino masses. In these lectures presented at TASI 2006, I review various realizations of leptogenesis and allude to recent developments in this subject.
Dynamic Passenger OD Distribution and System Performance of Taxi Operation System
Chen Mu,XiangMo Zhao
International Journal of Information Engineering and Electronic Business , 2011,
Abstract: The complexity of taxi operation system grows out of the inherent dynamics and randomness of taxi services. In this paper, we consider a taxi operation system to be a special structure queuing system, and present a simulation model of cruising taxi operation system. It is supposed that vacant taxis cruise in the city to search for passengers, and their search strategies are based on drivers’ experience and available information. With a given OD distribution, the dynamic features of the taxis’ 24-hour available service can be recurred. Through a simulation experiment, it is shown that considering the time-variant effect can help to get more accurate information about taxi services. A new method of determining the system optimal taxi fleet size is developed. These are helpful to taxi supervisor for regulating urban taxi operation system more efficiently and taxi drivers for providing better service.
Interval oscillation of second-order Emden-Fowler neutral delay differential equations
Mu Chen,Zhiting Xu
Electronic Journal of Differential Equations , 2007,
Abstract: Employing Riccati techniques and the integral averaging method, we establish interval oscillation criteria for the second-order Emden-Fowler neutral delay differential equation $$ [|x'(t)|^{gamma-1}x'(t)]'+q_1(t)|y(t-sigma)|^{alpha-1}y(t-sigma) +q_2(t)|y(t-sigma)|^{eta-1} y(t-sigma)=0, $$ where $tgeq t_0$ and $x(t)=y(t)+p(t)y(t- au)$. The criteria obtained here are different from most known criteria in the sense that they are based on information only on a sequence of subintervals of $[t_0,infty)$, rather than on the whole half-line. In particular, two interesting examples that illustrate the importance of our results are included.
Monotone iterative method for semilinear impulsive evolution equations of mixed type in Banach spaces
Pengyu Chen,Jia Mu
Electronic Journal of Differential Equations , 2010,
Abstract: We use a monotone iterative method in the presence of lower and upper solutions to discuss the existence and uniqueness of mild solutions for the initial value problem $$displaylines{ u'(t)+Au(t)= f(t,u(t),Tu(t)),quad tin J,; t eq t_k,cr Delta u |_{t=t_k}=I_k(u(t_k)) ,quad k=1,2,dots ,m,cr u(0)=x_0, }$$ where $A:D(A)subset E o E$ is a closed linear operator and $-A$ generates a strongly continuous semigroup $T(t)(tgeq 0)$ in $E$. Under wide monotonicity conditions and the non-compactness measure condition of the nonlinearity f, we obtain the existence of extremal mild solutions and a unique mild solution between lower and upper solutions requiring only that $-A$ generate a strongly continuous semigroup.
Ergodic convergence rates of Markov processes--eigenvalues, inequalities and ergodic theory
Mu-Fa Chen
Mathematics , 2003,
Abstract: This paper consists of four parts. In the first part, we explain what eigenvalues we are interested in and show the difficulties of the study on the first (non-trivial) eigenvalue through examples. In the second part, we present some (dual) variational formulas and explicit bounds for the first eigenvalue of Laplacian on Riemannian manifolds or Jacobi matrices (Markov chains). Here, a probabilistic approach--the coupling methods is adopted. In the third part, we introduce recent lower bounds of several basic inequalities; these are based on a generalization of Cheeger's approach which comes from Riemannian geometry. In the last part, a diagram of nine different types of ergodicity and a table of explicit criteria for them are presented. These criteria are motivated by the weighted Hardy inequality which comes from Harmonic analysis.
Speed of stability for birth--death processes
Mu-Fa Chen
Mathematics , 2010,
Abstract: This paper is a continuation of the study on the stability speed for Markov processes. It extends the previous study of the ergodic convergence speed to the non-ergodic one, in which the processes are even allowed to be explosive or having general killings. At the beginning stage, this paper is concentrated on the birth-death processes. According to the classification of the boundaries, there are four cases plus one having general killings. In each case, some dual variational formulas for the convergence rate are presented, from which the criterion for the positivity of the rate and an approximating procedure of estimating the rate are deduced. As the first step of the approximation, the ratio of the resulting bounds is usually no more than 2. The criteria as well as basic estimates for more general types of stability are also presented. Even though the paper contributes mainly to the non-ergodic case, there are some improvements in the ergodic one. To illustrate the power of the results, a large number of examples are included.
