There are no accurate mathematical methods for searching of solution for different problems of optimization for dynamical network characteristics. Some problems may be successfully solved by means of modeling, simulation optimization and other methods of modern cybernetics. The dynamical character of network causes problem of sufficient traffic capacity of data transmission system and admissible time delay because of variable volume of information flow or variable channel load. Sometimes the quantity of users may be so large, that network operation system may give a refuse and a set of messages may be lost. It is very important task to test network for stability work in case of different kinds of noise both amplitude and a distribution density.

Preventive theoretical analysis of these microscopic models is still very difficult. Based on the idea of diffusion approximation a technique is presented, how the mean value of a simple predefined agent-based SIR model can be calculated to asymptotically satisfy the classic SIR differential equations by Kermack and McKendrick. This technique can be generalized to contribute to the analysis of agent-based models and can help developing hybrid models.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114954040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reliability of the BGA are evaluated through shear test. Different parameters of the ball shear test will cause the change on stress and strain. In this paper, a simple shear test on a single solder ball joints on Ball Grid Array (BGA) with varied shear speed was simulated. Lead free solder Sn-3.5Ag-0.7Cu is used in this analysis. Simple Single Factor (SSF) experiment for a single factor was used to analyse the load effect on a single solder ball. Simulation of load effects on BGA was accomplished by using ANSYS Version 11. The results in load effect on the single solder joint of BGA was plotted. Result shows that the high shear speed test obtains greater shear forces compare to low shear speed test.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125584208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Realizing heterogeneous simulation platforms may benefit from many facilities of distributed computing. However, distributing simulation components over a network raises many challenges concerning communications, data exchange, numerical stabilities and others. A well-known solution that addresses some of these challenges is the High Level Architecture (HLA). The HLA is an industry standard for distributed simulation and interoperability. So far the HLA has been used in industry for Discrete Event Simulations (DES). In this paper it is presented how the HLA can also be employed for continuous simulations. Two HLA specific algorithms for distributing explicitly coupled continuous simulation components over the network are presented. The simulation components follow the Functional Mock-up Interface (FMI) specification. The FMI is a specification for model exchange and co-simulation among simulation tools. Any simulation component conforming to FMI, generated from any of the more than forty simulation tools that are supporting or planning to support the FMI, can be considered in the proposed architecture.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132258915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper the authors propose an extension for Modelica, an equation-based language for system modeling, that will allow to represent system requirements in the same formalism as the design model, thus reducing the need for transformations between different specialized formalisms, lowering maintenance and modification costs, and benefitting from the expression and simulation capabilities, as well as extensive tool support of Modelica. The object-oriented nature of the approach provides the advantages of modular design and hierarchical structuring of the requirement model. This paper also illustrates, with the help of an example, how requirement verification can be used alongside the simulation process to trace the components responsible for requirement violations. To this end, we introduce a formalism for expressing relationships between components and requirements, as well as a tracing algorithm.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133857120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using SimPy we created a layer of basic manufacturing objects, which we named Many (Manufacturing in Python). Many was tested in several model topologies for its accuracy, speed and expandability. In parallel to this work a Graphical User Interface (GUI) is being developed separately, but having in mind that the two modules will cooperate.

Many relevant studies have been performed by conventional integral schemes which can't control the error of Hamiltonian. In this paper, I will show the simulation results of double pendulum with the Hamiltonian conserved integral scheme. Non-dimensional Hamilton's equations of the double pendulum are derived. Initial values of the simulations are decided by mode analysis of the linearized system. Parametric survey is performed so that the system property may change from linear via non-linear to chaos. The results of simulations are as follows. The double pendulum which starts synchronously may change into the reverse steady mode by way of chaos-like behavior, even if it starts with small amplitude, which has been supposed to keep the same coupled harmonic oscillation. On the contrary, asynchronous mode keeps the same mode more moderately. The quantity Ln(d/T), where d is a deviation of one round trip, and T is a one round time, defined here shows a good indicator of chaos-like behavior.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126103190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our work, we expand the conventional HPC systems to run larger reservoir simulations on a heterogeneous grid of HPCs. This expansion is accomplished by developing a unique domain decomposition technique to achieve higher load balancing and computational efficiency on the grid. The decomposer works as an adaptive detector of the available hardware resources on the grid, learns about the different processor speeds and adjusts its load distribution among the CPUs. As a result, our grid implementation for reservoir simulation outperforms the conventional methods of domain decomposition, which are designed to run on homogenous set of processors in a cluster.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127511579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its most important advantages are high efficiency, low operating temperature and high power density, while the high price, limited reliability and durability are the notable shortcomings. The improvement in these parameters can be achieved by the proper dimensioning of all components in the system and designing its controls for a particular application. To facilitate this process, a model of the entire unit has been built, consisting of a FC stack and important supporting components. The modeled main sub-processes within the stack are the electrochemical process and the energy balance. The supporting subsystems, so called balance of plant (BoP) components, comprise the cooling system model, the blower and the air-flow model. Additionally, a model for estimation of the BoP components' power consumption is integrated. The paper presents the models of the above-listed systems and their characteristics. The evaluation is done upon the comparison of model outputs against measurements carried out on commercial PEM FC system.
