作者： LU Ning WANG Yulong SHI Wenbo LI Guorui DIAO Ding northeastern university Nanjing university of Information Science and Technology Beijing university of Posts and Telecommunications

This paper focuses on selecting the appropriate filtering location to minimize the amount of filtering routers in the traceback-based packet filtering for defending against the large-scale Bandwidth denial-of-service(BDo S) *** filtering location can be viewed as a resource allocation problem and further we formulate it to an integer linear programming model and design an exact and computationally efficient filtering location *** evaluation results show that our algorithm brings significant benefits in practice.

A prey-predator model with allee effect and functional response is established, which considers strong allee effect and weak alle effect on the prey-predator ecosystem. Boundedness and positiveness of solution of model system as well as existence of equilibria of model system is studied. By performing local stability analysis, locally asymptotical stability of model system around equilibria is investigated. Furthermore, a Lyapunov function is constructed to analyze the globally asymptotical stability of the proposed model system . Finally, numerical simulations are carried out to show efficiency of the theoretical analysis obtained in this paper.

Due to the complexity of interaction among constituents inside the whole system, it is difficult to establish accurate mathematics models to describe and analyze the complex systems exactly. There are few attempts concerning on the moving process of endocrine disruptor in human bodies, which have been the polluted material worldwide related to the reproduction, existence and development of human being. Focusing on such two challenging issues, a multi-compartment model of endocrine disruptor Benzene moving in the human body complex system is established in this paper. Furthermore, passivity of this model is described systematically. A feedback controller for this descriptor biological complex system is used under the station of strict passivity, and an example of the controller is given for a particular instantiation of the model.

In this paper, a stage structured prey-predator-resource model with maturation delay is established, where resource biomass is harvested. Persistence of solutions of model system is studied. Dynamic analysis of model system with maturation delay is investigated, which shows that interior equilibrium loses its stability at some critical values of maturation delay and economic interest of harvesting. Further discussion shows that maturation delay to preserve stability increases with the introduction of harvest effort into bioeconomic prey-predator-resource model.

The waste transfer station allocation optimization of urban life is an important part in the process of garbage disposal. According to M/M/S queuing model and relevant statistical data, waste transfer station allocation of qinhuangdao is investigated based on queuing service system in this paper. The proposed model is studied by using computer simulation, and simulation results reveal that there are some disadvantages for the existing resources and services management, such as the average queue length lasts for bigger, and the customer usually waits for a long time. In view of the above shortcomings, queuing theory method is utilized for allocation optimization research. In the case of compression equipment number is 2, optimal service rate μ*= 11.1516 is obtained in this paper, which is higher than the current service rate and the cost of queuing service system in waste transfer station can be reduced by improving the service rate. Furthermore, in the case of service rate unchanged, the optimal service number s*= 3 is obtained and a compression equipment can be applied in the model to make the system optimized. Finally, numerical simulations are carried out to show efficiency of the theoretical analysis obtained in this paper.

In this paper, we investigate a prey predator model system with selective harvest effort on predator, where prey refuge is considered and taxation is utilized as a control instrument to protect the population from *** which influence positiveness and boundedness of solutions of model system are studied. Local stability analysis around all equilibria of model system are discussed due to variation of prey refuge and taxation. Furthermore, global stability of model system around the positive equilibrium is investigated based on Bendixson criterion. By using Pontryagin’s maximum principle, an optimal taxation control is derived to ensure the sustainable development of biological resource and prosperous commercial harvesting.

This paper deals with an H∞ filtering problem for a class of stochastic time-delay nonlinear systems. The Itotype stochastic disturbances, nonlinear term and time-varying delay appear in the system under consideration. In terms of free-weighting matrix method and a new Lyapunov functional, we derive a new sufficient condition for analyzing mean-square stable with H∞ norm bound γ of the filtering error system. Both the desired filter analysis and synthesis problems are investigated, and the existence condition of the filter is proposed by the linear matrix inequalities(LMIs).Finally, an example is provided to show the effectiveness of the proposed design approach.

A static dial-a-ride problem with time windows is investigated, without wait while carrying passengers and maximum ride time constraints as the service quality. A parallel insertion heuristic based on the spatial and temporal aspects is presented. The proposed algorithm firstly sorts the requests based on the earliest pickup time and decentralization index alternately and initializes the routes with seed requests. Then a insertion-rejected-reinsertion operation is performed, in which the spatial aspect as the granular is also considered. Simulation results indicate that the proposed algorithm reduces costs effectively, compared with the algorithms only considering the temporal aspect and no seed requests. Also, sensitivity analysis indicates that the required vehicle number is insensitive to the granular extent and the initial vehicle number.
