THE M/PH/1 QUEUE WITH WORKING VACATIONS AND VACATION INTERRUPTION

引用

Journal of Systems Science and Systems Engineering 2010年第4期19卷 496-503页

作者： Yutaka BABA Faculty of education and Human Sciences Yokohama National University

We study an M/PH/1 queue with phase type working vacation and vacation interruption where the vacation time follows a phase type distribution. The server serves the customers at a lower rate in a vacation period. The server comes back to the regular busy period at a service completion without completing the vacation. Such policy is called vacation interruption. In terms of quasi birth and death process and matrix-geometric solution method, we obtain the stationary queue length distribution. Moreover we obtain the conditional stochastic decomposition structures of queue length and waiting time when the service time distribution in the regular busy period is exponential.

关键词： Working vacation vacation interruption phase type distribution quasi birth and death process matrix-geometric solution stochastic decomposition

A Debris-flow Simulation Model for the Evaluation of Protection Structures

引用

Journal of Mountain Science 2007年第3期4卷 193-202页

作者： TSAI Yuanfan Associate Professor of Social Studies education National Taipei University of Education

Debris flow is the flow of a solid-fluid mixture and in this investigation it is treated as the flow of a continuum in routing. A numerical model is proposed describing debris flow including erosion and deposition processes with suitable boundary con-ditions. The numerical model is applied to evaluate the effects of protection structures against debris flow caused by heavy rainfall on the Shen-Mu Stream of Nantou County located in central Taiwan. Simulation results indicated that the proposed model can offer useful pre-planning guidelines for engineers.

GENERAL DECAY OF A TRANSMISSION PROBLEM FOR KIRCHHOFF TYPE WAVE EQUATIONS WITH BOUNDARY MEMORY CONDITION

Acta Mathematica Scientia 2014年第5期34卷 1395-1403页

作者： Sun Hye PARK Center for education Accreditation Pusan National University

In this paper, we investigate the influence of boundary dissipation on the de-cay property of solutions for a transmission problem of Kirchhoff type wave equation with boundary memory condition. By introducing suitable energy and Lyapunov functionals, we establish a general decay estimate for the energy, which depends on the behavior of relaxation function.

Forest insect assemblages attracted to light trap on two high mountains(Mt. Jirisan and Mt. Hallasan) in South Korea

引用

Journal of Forestry Research 2016年第5期27卷 1203-1210页

作者： Pyae Pyae Thein Sei-Woong Choi Department of Environmental education Mokpo National University

Assemblages of forest insects across two high mountains （Mt. Hallasan： JJ and Mt. Jirisan： JR） in South Korea were compared by collecting insects using an ultraviolet light trap at 20 sites （200-1700 m elevation ranges） from May to October 2013. A total of 2960 individuals, representing 481 species of 10 orders, were collected on JJ, compared with 7080 individuals representing 769 species of 14 orders on JR. The estimated number of species on JJ was 667 compared with 952 on JR. The differentiation among habitats （[3-diversity） was higher on JJ （4.95） than JR （4.33） because of the island characteris- tics of JJ. Six insect orders （Lepidoptera, Coleoptera, Diptera, Hymenoptera, Hemiptera and Trichoptera） were dominant on both mountains, suggesting that the light trap captures represented well the insect fauna and is an effective method for investigating forest insect diversity. We concluded that forest insect assemblages on mountains are mainly affected by the elevation and the dominant forest in each elevation. In addition, the insect fauna on each mountain was differentiated by the habitat, which could be correlated with geological history.

Attractors for a von Karman equation with memory

引用

Science China Mathematics 2015年第12期58卷 2505-2516页

作者： PARK SunHye Center for education Accreditation Pusan National University

In this paper a von Karman equation with memory,utt + α?2u- γ?utt- integral from n=-∞ to t μ(t- s)?2u(s)ds = [u, F(u)] + h is considered. This equation was considered by several authors. Existing results are mainly devoted to global existence and energy decay. However, the existence of attractors has not yet been considered. Thus, we prove the existence and uniqueness of solutions by using Galerkin method, and then show the existence of a finitedimensional global attractor.
