Time Delay Induced Oscillation: An Example on a Class of n Coupled Van Der Pol Oscillators Model with Delays  [PDF]
Chunhua Feng, Carl S. Pettis
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.36087
Abstract: In this paper, a class of n coupled van der Pol oscillator model with delays is considered. By employing an analysis approach, some sufficient conditions to guarantee the existence of stability and oscillations for themodel are obtained. Examples are provided to demonstrate the results.
Oscillatory Behavior of a Network Epidemic SIS Model with Nonlinear Infectivity  [PDF]
Chunhua Feng, Carl S. Pettis
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.51021
Abstract:

In this paper, an epidemic SIS model with nonlinear infectivity on heterogeneous networks and time delays is investigated. The oscillatory behavior of the solutions is studied. Two sufficient conditions are provided to guarantee the oscillatory behavior for the solutions. Some computer simulations are demonstrated.

On China’s Cooperation Patterns and Operational Mechanisms among Industry, Universities and Institutes
Chunhua Feng,Baojun Sun
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n10p230
Abstract: As an outcome of market economy, the cooperation among industry, universities and institutes still lies in its preliminary stage. The combination of the three results from technological innovation and transfer of achievements and it is driven by market demands and policy guidance. Since its operational pattern and mechanism serve as the key to the success in the cooperation among industry, universities and institutes, this paper summarizes the typical pattern and mechanism of China’s cooperation among industry, universities and institutes, which is followed by further analysis.
On the Existence of Almost Periodic Solutions for Some
一类非齐次时滞微分方程概周期解的存在性

Feng Chunhua,
冯春华

数学物理学报(A辑) , 2006,
Abstract: A set of sufficient conditions is derived for the existence of almostperiodic solutions for some nonhomogeneous delay differentialequations by using exponential dichotomy and fixed point theorem.This criterion provides a method for the existence analysis ofalmost periodic solution of some nonhomogeneous time delaysystems.
Analysis on Structural Benefit of Jilin Cultural and Creative Industries
Wen FANG,Fang HU,Chunhua FENG
Management Science and Engineering , 2010,
Abstract: Cultural Creative Industry is a new industry in 21 century, and is also a new growth point in the local economic development. In recent years, Cultural Creative Industry in Jilin Province has made remarkable development and has greatly promoted the local economic growth. The paper estimates the structural benefit of Cultural Creative Industry in Jilin Province by using the structural deviation and comparable labor productivity index, and researches the allocation proportion and correlations of the elements of labor and capital in the industry, accordingly unearth the problems existed in the internal structure of the industry and provide counter planes to the coordinated growth of the industry. Key words: Cultural Creative Industry; Structural Benefit; Structural Deviation; Comparative Labor Productivity
Problems and Countermeasures on China’s Cooperation of Industry, Universities and Research Institutes
Chunhua Feng,Jing Kang,Baojun Sun
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n9p170
Abstract: The cooperation of industry, universities and research institutes is an outcome of the development of science, technology and higher education to certain degree, a manifestation of higher education’s adaptability to economic development and its combination with social production as well as an inevitable choice in market economy and the era of knowledge economy. In spite of certain accomplishments made in China’s cooperation of industry, universities and research institutes since reform and opening, there are still a lot of problems and shortages compared with that in developed countries.
Policy Suggestions on Innovation and Development of China’s Industry-University-Research Strategic Alliance
Chunhua Feng,Dianwei Qi,Baojun Sun
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v6n1p269
Abstract: As is shown in the latest achievements in scientific research and major developed countries’ relevant experience, industry-university-research strategic alliance serves as a crucial way to improve independent innovative ability. With such alliance being an important path to achieve independent innovation and innovative system with Chinese characteristics, government is expected to enhance its policy guidance and create favorable policy environment during industry-university-research cooperation.
Research on the Social Responsibility of Corporations in China
Dianwei Qi,Chunhua Feng,Meina Jin
Asian Social Science , 2012, DOI: 10.5539/ass.v8n15p184
Abstract: It is the consensus of the Chinese enterprises to focus on the sustainable development of enterprises and society and emphasize responsibility and contribution. Compared with the large and medium-sized enterprises, the small and medium enterprises (SME) have fulfilled certain social responsibility and played an irreplaceable role in promoting economic growth, increasing employment, technological innovation and social harmony and stability.

A Comparison Research on Industry-University-Research Strategic Alliances in Countries
Chunhua Feng,Mengchun Ding,Baojun Sun
Asian Social Science , 2010, DOI: 10.5539/ass.v7n1p102
Abstract: With the tide of global economic integration, the Industry-University-Research cooperation plays an extremely important role in economic development. Hence, all countries in the world stress the research on Industry-University-Research strategic alliance. Some developed countries, such as America, German, and England, have built appropriate modes for Industry-University-Research strategic alliances based on national conditions. The strategic alliance based on combination of different countries, enterprises, and institutes has been becoming a new way for technology transfer.
Selection of Modes of Cooperation among Industries, Universities and Research Institutes
Chunhua Feng,Mengchun Ding,Baojun Sun
Asian Social Science , 2010, DOI: 10.5539/ass.v6n10p97
Abstract: Innovation of cooperation among industries, universities and research institutes has played an extremely important role in the process of economic development, so countries throughout the world all attach great importance to study on models of cooperation among industries, universities and research institutes. At the present time of economic globalization, informationization and networking, traditional modes of cooperation among industries, universities and research institutes no longer adapt to requirements of development of the new situation and modes of cooperation among industries, universities and research institutes also call for continuous reform. We should select effective modes of cooperation among industries, universities and research institutes and make more contributions to the economic development.
