Abstract: In this paper, the subsurface flow wetland sewage treatment mathematical model is studied. the analytical solution is obtained by using the Laplace transform technique for non-steady subsurface flow wetland model and the diffusion characteristics for some parameters used in the model are analyzed. Then the solution for the model which is added by the source is obtained on two boundary conditions by the adomian decomposition method. The examples are given compare the approximate solution and the exact solutions.

Abstract: Nowadays, business process has the problem of no unified standard, the lack of machine-understandable semantics and so on. Thus, in order to make the business analysts and IT staff have no communication obstacles to process modeling, we may make use of the standard that both sides can understand to express business process-introducing ontology technology. Therefore, this paper, from the bottleneck of logistics distribution business process, constructs logistics distribution domain ontology, and adds semantics for business process. It helps to achieve business process automation and intelligent, and may reduce the workload of user. At the same time, we also solve the problems of the concept sharing and information integration in logistics distribution field.

Abstract: Equipment maintenance support simulation experiment (EMSSE) is a method of studying maintenance support problem about decision-making about uncertain support scheme alternatives. Aiming at the character of complexity and uncertainty on the warship equipment maintenance support system, a type of structure applied to the warship equipment maintenance support simulation system was brought forward to support EMSSE based on the functional demand of system, and the interface layer, running-time layer, and data layer were analyzed in detail , and the executing process was designed. Finally, a warship maintenance support simulation system (WMSSS) which was developed and realized based on system design, which was used to make an experiment. The result of simulation experiment validates that WMSSS is feasible and reasonable to supply uncertain decision assistance for warship maintenance equipment support.

Abstract: In the field of SoC hardware/software co-design, transaction level modeling is the bridge of SoC system level modeling and RTL level modeling. This paper considers a novel application specific template reuse approach for SoC transaction level modeling. Application specific architecture templates are built by integrating computation, communication and scheduling IP modules. These templates can support SoC modeling, mapping and simulation simultaneously. Experiments results from JPEG encoder applications in TL_Platform Creator show the approach can improve the quality and efficiency of SoC design greatly.

Abstract: OONS is a new Object Oriented Neural Simulator. The goal creating it is making the construction of neural model as quickly and easily as possible for the users, and can run in shorter time than other simulators. OONS is written in C++ programming language and using crank-Nicholson implicit integral method to allow for efficient simulations. Because of multi-level package, it is suitable both for beginners and for experts, especially the simulating algorithm researchers. We test OONS by Rallpacks benchmark set, the results show that OONS is higher efficient and more precision.

Abstract: In order to achieve efficient management of the dam, the new algorithms such as reinforcement learning, Synergetic, Structural Risk Minimization and Particle Swarm Optimization are used to establish a Cooperative Wavelet Least Squares Support Vector Machine Model. To improve the convergence rate and make full use of knowledge and advice of mechanics and hydraulics of the dam, WLS-SVRM and WLS-SVCM models are used cooperatively. Before the training online, mapping provides training samples for WLS-SVCM. During the course of training online, the numerical simulation and WLS-SVCM will provide knowledge and advices for WLS-SVRM. Case study shows that the model can provide timely information of gate opening and management information of the dam so as to provide decision support for engineering management.

Abstract: Using self-made high-ferric-based silicon coagulant to deal with the lead containing industrial wastewater. Firstly we can define the optimum dosage of coagulant by jar test, and then utilize orthogonal experiment to seek the best energy consumption allocation decision at different levels. Combining with the fractal dimension of flocs, it can directly reflect the flocs growth of each stage in the distribution of energy consumption, and can guide the operating conditions of coagulation technology. This method not only makes water treatment economical and efficient, but also offers the comparatively scientific design data for the design of the flocculation tank in water works.

Abstract: Driving behavior research is the hot spot in the field of transportation nowadays owning to the stern traffic safety. The visual perception model based on bounded rationality has incorporated the attention distribution and concentration; driving fatigue; driving experience and visual information retrieve which provides a vivid simulation of real driver’s visual perception procedure and it lays the foundation for the study of driver’s decision and manipulation behavior.

Abstract: To resolve the problem of the credibility evaluation in conjoint simulation systems, it discusses the background of emergence of conjoint simulation and focuses on the credibility, including definition, prevalent methods and characteristics. Taken a satellite network simulation system as an example, the Fuzzy Analytic Hierarchy Process (FAHP) is used to perform the evaluation work.

Abstract: Based on spherical head models, this paper, by employing the finite element method (FEM), analyzes the potential distribution of the brain scalp surface and attempts to work out the electroencephalography (EEG) forward problem, in hope of finding out the impact the dipole parameters has on it. According to the electromagnetism theory, this paper discusses the general resolution of EEG, it requires electric potentials of the globe's surface, and graphically displays results of computation through finite element post-processing, which tests their effectiveness. Furthermore, it analyzes the influences of dipole parameters on the potential distribution of scalp surface, such as position, direction and strength, which attempts to provide an effective method to solve EEG forward problem, based on diversified head model, and also proposes a prior information to the solution to EEG inverse problem.
