An Overview on the Team Interaction Process  [PDF]
Yan Wang
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.612001
Abstract: Team interaction process contains three stages: input, process and output. The effectiveness of team interaction is the decisive factor of team competition. Nowadays, many scholars study on team interaction process based on a particular view, but few scholars put up with an overview on the whole team interaction process research results. Based on the predecessors’ researches and centered on the team interaction process, this paper outlines the three stages and its elements, the influence to team performance and measurements of team interaction. This paper also puts forward some prospects finally.
Sensor Scheduling Algorithm Target Tracking-Oriented  [PDF]
Dongmei Yan, Jinkuan Wang
Wireless Sensor Network (WSN) , 2011, DOI: 10.4236/wsn.2011.38030
Abstract: Target tracking is a challenging problem for wireless sensor networks because sensor nodes carry limited power recourses. Thus, scheduling of sensor nodes must focus on power conservation. It is possible to extend the lifetime of a network by dynamic clustering and duty cycling. Sensor Scheduling Algorithm Target Tracking-oriented is proposed in this paper. When the target occurs in the sensing filed, cluster and duty cycling algorithm is executed to scheduling sensor node to perform taking task. With the target moving, only one cluster is active, the other is in sleep state, which is efficient for conserving sensor nodes’ limited power. Using dynamic cluster and duty cycling technology can allocate efficiently sensor nodes’ limited energy and perform tasks coordinately.
A Seven-Dimensional System of the Navier-Stokes Equations for a Two-Dimensional Incompressible Fluid on a Torus  [PDF]
Heyuan Wang, Yan Gao
Open Journal of Fluid Dynamics (OJFD) , 2014, DOI: 10.4236/ojfd.2014.44026
Abstract: A seven-mode truncation system of the Navier-Stokes equations for a two-dimensional incompressible fluid on a torus is considered. Its stationary solutions and stability are presented; the existence of the attractor and the global stability of the system are discussed. The whole process, which shows a chaos behavior approached through instability of invariant tori, is simulated numerically by computers with the changing of Reynolds number. Based on numerical simulation results of bifurcation diagram, Lyapunov exponent spectrum, Poincare section, power spectrum and return map of the system, some basic dynamical behaviors of the new chaos system are revealed.
The Introduction of Specific Water and Maximum Airborne Specific Water & the Improvement of Dynamic Equations on Non-Uniform Saturated Moist Atmosphere  [PDF]
Xingrong Wang, Yan Feng
Atmospheric and Climate Sciences (ACS) , 2015, DOI: 10.4236/acs.2015.53018
Abstract: To eliminate the irrational supposition that condensed liquid water always falls immediately, specific water m?and maximum airborne specific water mm are introduced into the dynamic framework on non-uniform saturated moist atmosphere (m?is the ratio of the airborne liquid water mass to the moist air mass in unit cubage moist air, mm is its maximum value with \"\" , \"\" , \"\" and \"\" are airborne coefficient, vertical velocity and saturated specific humidity respectively). The balance equation between water vapor and airborne liquid water is derived. From the balance equation, a new formula of precipitate rate is got. The analysis shows that in the air stream with some upward vertical velocity (\"\" ), the condensed liquid water can precipitate under the condition with \"\" (q is specific humidity) and?\"\" only, otherwise it is detained in the air and becomes airborne liquid water. Not only does precipitating liquid water contain condensed liquid water, but also contains converged and existing airborne liquid water. Following above discussion, improved dynamic equations on non-uniform saturated moist atmosphere are provided.

Urban Development and Water Management in the Yangtze River Delta  [PDF]
Yan Wang, Wei Wu
World Journal of Engineering and Technology (WJET) , 2018, DOI: 10.4236/wjet.2018.62B002
Throughout the history of the world, the development of the cities are related to the large water systems and the ocean. Where the river is abundant, the trade and regional centres could be formed. However, along with the prosperity of the water-cities, massive urban construction and environmental issues are enormous challenges in human process. A “scientific” urban planning, “Sponge City”, “Resilient City”, regional and urban culture and characteristics get more and more attention. The theme of “water and city” is clearly of great historical value and practical significance for the new resilient urban and water management strategies. The paper will summarize characteristics of geographical, historical, socio-cultural and political realms in metropolitan deltas and the historical governance as well as the recent developments in the Yangtze River Delta. It will introduce urban development and water management in four water cities: the canal and the city-Yangzhou, the river and the city-Nanjing, the lake and the city-Suzhou and the sea and the city-Shanghai. And then it will analyze the inner motivation of the interaction between water and cities in Yangtze River Delta. Furthermore, learning from successful historical experiences, the paper will provide suggestions for future sustainable urban development.

Progress on Research for the Treatment of HIV/AIDS with Traditional Chinese Medicine in China  [PDF]
Jian Wang, Bi Yan Liang
World Journal of AIDS (WJA) , 2011, DOI: 10.4236/wja.2011.13016
Abstract: The mortality rate associated with HIV/AIDS has decreased dramatically after highly active antiretroviral therapy (HAART). However, issues such as viral reservoirs, drug resistance and side effects have led to a significant crisis in the management of HIV/AIDS. It has become evident that HAART does not offer a complete solution to the problem. Therefore, additional and alternative therapeutic strategies urgently need to be explored. Traditional Chinese medicine (TCM) is one of the mainstays of complementary and alternative medicine, and its use has aroused increasing attention. This paper reviews the recent progress in the use of TCM, from single herbs, herbal ingredients, compound Chinese herbal medicine, acupuncture and medical care, for the treatment of HIV/AIDS in China. We also review evaluation systems that assess the efficacy of TCM.

Management Science and Engineering , 2009,
Abstract: A game with parameter for substitute public goods provision is constructed by using non-cooperative game methods. During the voluntary provision of public good, the influence to individual action of the government behavior and strategic selection of contributors are analysed. Further, incentive mechanism for public goods provision is discussed. For this problem, a cooperative game for public goods provision is constructed, in which the core of game are coincident with Lindahl allocation. So this allocation meets individual rationality and collective rationality. Key Words: Substitute Public Goods; incentive mechanism; core; Lindahl allocation
The Effect of Text Length on Students Reading Comprehension
Yan Wang
Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.1.9.1160-1166
Abstract: This study investigated the impact of text length on reading comprehension. Three reading comprehension passages accompanied by 30 items were reduced to two thirds of their original lengths. The truncated versions along with the original version were randomly administered to 100 male and female college students of English (50) and non-English majors (50). Although the participants performed marginally better on the shortened version of the test, a two-way ANOVA revealed that the length of the text did not have any statistically significant effect on the students' performance on the two versions of the test. No interaction between the length of the test and the students' major was found either. Further analysis of the data indicated that sex did not have any significant effect on the performance of the students on the two versions of the test. The article concludes with suggestions for further investigations into the issue in question.
