Community Fragmentation? A 15-Year Study of Residents Perception on Tourism Development  [PDF]
Xinqi Wu, Hong Hui
Journal of Service Science and Management (JSSM) , 2018, DOI: 10.4236/jssm.2018.116041
Abstract: Tourism development may result in polarization among the community residents with simple social relations, mutual misunderstanding or even hostility between the foreign residents and indigenous residents. Such conflict and estrangement between resident relationship is called the “effect of community fragmentation” of tourism development. Based on a study of Ciqikou, which is an ancient town, this paper found that, the “effect of community fragmentation” did exist and such effect may cause the “crowding-out effect”, which would influence the continuous development of tourism. Therefore, the paper proposes that a new benefit mechanism for tourism must be explored, to benefit all the residents in scenic region from the tourism development; to avoid the “crowding-out effect”, legislation based on house reservation to indigenous residents must be enacted to ensure their residences would not be occupied by external capital; tourism development must take the realization of community development as the basic target.

A Modified Wallman Method of Compactification  [PDF]
Hueytzen J. Wu, Wan-Hong Wu
Advances in Pure Mathematics (APM) , 2013, DOI: 10.4236/apm.2013.36076
Abstract:

Closed \"\" and basic closed C*D-filters are used in a process similar to Wallman method for compactifications of the topological spaces Y, of which, there is a subset of C*(Y) containing a non-constant function, where C*(Y) is the set of bounded real continuous functions on Y. An arbitrary Hausdorff compactification (Z,h) of a Tychonoff space X can be obtained by using basic closed C*D-filters from \"\" in a similar way, where C(Z)

The Value and Size Effect — Are There Firm-Specific-Risks in China’s Domestic Stock Markets?
Hong Wu
International Journal of Economics and Finance , 2011, DOI: 10.5539/ijef.v3n3p26
Abstract: The Fama-French three-factor asset pricing formula is applied to the Chinese A-share markets: Shanghai and Shenzhen Stock Exchanges (SSE and SZSE). The benchmark explanatory returns—value and size premiums are constructed and adopted in the cross-sectional regressions. Market beta has no explanatory power. There are some evidences of the value effect only for the SSE. No significant size effect was found. The results are robust with or without the influences of the exchange rate reform and the recent financial crisis. The model works better in general for the SSE than for the SZSE, regardless of the specifications. There may well be different fundamental forces in the two markets. The pricing regularities pervasive in most equity markets do not explain the Chinese markets sufficiently well.
Yb-Decorated Carbon Nanotubes As a Potential Capacity Hydrogen Storage Medium  [PDF]
Hong-Wen Lei, Hong Zhang, Wei-Dong Wu
Modeling and Numerical Simulation of Material Science (MNSMS) , 2013, DOI: 10.4236/mnsms.2013.31B003
Abstract: We report a first-principles study, which demonstrates that a single Yb atom coated on a single-walled nanotube (SWNT), B atom doped CNT and N atom doped CNT binds up to six hydrogen molecules. At high Yb coverage we show that a SWNT can strongly adsorb up to 3.18 wt% hydrogen. Yb-4f electrons have no contribution on the adsorp-tion of hydrogen molecules in Yb doped CNT. The charge analysis results show that 4f electrons remain in Yb. These results promote our fundamental understanding of dissociative adsorption of hydrogen in RE atom doped carbon nano-structures.
Modal Analysis of Linear Mesoscale Convective System in Fujian Heavy Rainstorm  [PDF]
Hong Guo, Meijin Huang, Xingyu Wu, Wei Hong, Tingting Li
Journal of Geoscience and Environment Protection (GEP) , 2018, DOI: 10.4236/gep.2018.69001
Abstract: This paper uses the daily precipitation observation data and Doppler weather radar observation data from 2017 observatories and regional automatic stations in Fujian, China from 2009 to 2015. The characteristics of formation mode, organization mode, moving direction and duration of linear mesoscale convective system during non-typhoon continuous rainstorm in Fujian were analyzed. This paper gives the definition of linear mesoscale convective systems, trailing and parallel mesoscale convective systems. The above characteristics of the linear mesoscale convective system during the continuous heavy rain in Fujian differ greatly from the non-sustained heavy rain process: The linear mesoscale convective system in the continuous heavy rain in Fujian is mainly constructed later, and the trailing and parallel mesoscale convective system is conducive to the occurrence of continuous heavy rain in Fujian. The moving direction of the linear mesoscale convective system and convective monomer is mainly in the east direction, and the system duration is mostly 4 - 10 hours. The formation time of the monomer to form a linear convection time is mainly 1 - 3 hours, which is 2 hours earlier than the organization process of the general linear mesoscale convective system. The linear convective system formed to a dead time of an average of 5 hours, slightly longer than the general linear mesoscale convective system.

Weidong Liu, Jiang Wu, Hong Shen
Wireless Sensor Network (WSN) , 2010, DOI: 10.4236/wsn.2010.212112
Abstract: Due to the power limitation of nodes in wire-less sensor networks (WSNs), how to maximize network lifetime has become a critical issue for deployment of WSNs. Although several schemes have been proposed for 2D WSNs, few for 3D WSNs are known. In this paper, we present a scheme to maximize network lifetime for 3D WSNs through balancing energy consumption, as an extension of the existing scheme for 2D WSNs proposed recently [1]. Same as [1], we formulate the energy consumption balancing problem as an problem of optimal distribution of transmitting data by combining the techniques of sphere-corona based network division, mixed-routing and data aggregation. We first present a Tiled-block based routing scheme in order to balance energy consumption among nodes in each sphere-corona. Then we design an algorithm to compute the optimal distribution ratio of transmitting data between direct and hop-by-hop transmission, with the purpose of balancing energy consumption among nodes across different sphere-coronas. We show maximizing network lifetime through computing the optimal number of sphere-coronas. Afterwards a energy consumption balanced data collecting protocol (ECBDC) is designed and a solution to extend ECBDC to largescale WSNs is also presented. Simulaiton results show that ECBDC is superior to conventional direct and multihop transmission schemes in network lifetime.
Study on the Mechanism of Heterogeneous Catalysis (3) —The Catalysis of W, Mo, S and SiO2 on Carbon Dissolving and Mechanism of Carbon Dissolving in the Iron-Graphite Compact  [PDF]
Jiamin Jin, Tou Hong, Juqing Wu
Journal of Materials Science and Chemical Engineering (MSCE) , 2017, DOI: 10.4236/msce.2017.511007
Abstract: This is an article that validates Electron Cyclic Donate-Accept Catalysis Mechanism-ECDAM or Electron Orbital Deformation-Recovery Cycle Catalysis Mechanism-EODRM. In this paper, the influence of compact density, sintering temperature and time, vacuum degree, atmosphere and alloying element on the carbon dissolving rate into γ-Fe were studied. The experiment results have been reported. The way that the carbon is dissolved into γ-Fe was discussed. Gas phase composition and temperature play an important role on the carbon dissolving rate. The carbon gasification reaction is the determining step of dissolving carbon process. K2CO3, W and Mo are a catalysts, and their active size are K2CO3 > W > Mo. S and SiO2 are a poison, and their poison size are SiO2 > S. The experiment results are completely consistent with the original judgment of ECDAM.

Advances in Materials Physics and Chemistry (AMPC) , 2012, DOI: 10.4236/ampc.2012.24B053
Abstract:

The paper bulids a countercurrent multi-effect drying process model which can be expressed as a linear programming(LP) problem with the minimum total energy consumption as target function. Based on the model it can be conventient to solve the heat load , degree of drying and other drying parameters of each effect. And it realizes the mathematical simulation an analysis of multi-effect drying process. Such process not only reuses the secondary steam but also utilizes the high energy grade. Drying silica sand using 1-effect drying to 5-effect drying is presented as an example. The energy consumption and energy saving rate are compared by using co-current multi-effect drying and countercurrent multi-effect drying. As a summary, the countercurrent multi-effect drying is better than co-current drying. Considered the equipment investment and energy conservation, the study also concluded that the countercurrent 4-effect drying is the optimum selection, and it can save 57.6% energy compared to countercurrent 1-effect drying.




Assessment of the Spatial and Temporal Water Eutrophication for Lake Baiyangdian Based on Integrated Fuzzy Method  [PDF]
Shuxuan Liang, Hong Wu, Yihong Wu, Hongbo Li
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.41013
Abstract:

Water quality evaluation entails both randomness and fuzziness. Considering that water eutrophication evaluation involves many indices, different classifications and interval values, fuzzy variable sets theory was developed to Lake Baiyangdian as a study case. Taking reference to eutrophication standard of Chinese lakes and local characteristic of Lake Baiyangdian, eutrophication degree of lake was divided into 8 levels. Total phosphorus, total nitrogen, and CODMn were selected as evaluation indices in this research. Based on the measured data, index feature value matrix of sample was built. Index weights were determined by means of pure threshold value method. Relative membership degree of each index to each classification was calculated with relative difference function model. Then the stability of feature value of classification corresponding was received by the comprehensive calculation with the relative membership degree and index weights. The results show that the proposed models are effective tools for generating a set of realistic and flexible optimal solutions for complicated water quality evaluation issues. It concluded that the model was reasonable and practical.
