    This paper presents multiple neural-network models to mimic a nonlinear dynamic system. The multiple neural network models consist of one or more simplified time-varying functions to dynamically approximate the nature of the physical phenomena to be interpolated and extrapolated. The purpose of using the multi-model function is to perform a real-time approximation for a complicated nonlinear syste... View full abstract»

    The data distribution management (DDM) service provided by the High Level Architecture (HLA) run-time infrastructure (RTI) is aimed at making data communication more efficient by sending data only to those federates who need the data, as opposed to the broadcasting mechanism employed by distributed interactive simulation (DIS). Several DDM methods, including class-, region and grid-based, have app... View full abstract»

    Computer simulations are extensively used for business and science applications. However a simulation generically generates a certain class of dynamical system whose properties are poorly understood. We address some theoretical issues of computer simulations and illustrate our concepts for the simulation of circular one-lane traffic. We propose a certain class of discrete dynamical systems (SDS) t... View full abstract»

  • Performance analysis of multiprocessor architectures via analytical simulation

    Publication Year: 2000, Page(s):326 - 332
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (268 KB)

    The performance analysis of network architectures is a very crucial factor in designing multiprocessor systems. Very often, simulation is the only feasible method because of the nature of the problem and because analytical techniques become too difficult to handle. However simulation can be costly to develop and run. The mathematical analysis approach is preferable but in most cases not applicable... View full abstract»

    Large software systems are composed of interdependent distributed components, some developed in-house, some commercially available, and others developed by the customer. The system architecture, that is, the components comprising the system and their interconnections, typically varies for each design. Performance prediction is important for such software, including helping designers to select bett... View full abstract»

    A coordinated animation (CA) depicts the (internal) operations of a model along with action in the modeled domain. This paper's CA involves neural network models as the internal system to animate. A range of situations, mainly for the movement of objects in a laboratory setting, constitute the modeled domain, effecting a model-domain combination that may be “ideal” for realizing CA in ...

    We present an algorithm which integrates flow control and dynamic load balancing in Time Warp. The algorithm is intended for use in a distributed memory environment. Our flow control algorithm makes use of stochastic learning automata and is similar to the leaky-bucket flow control algorithm used in computer networks. It regulates the flow of messages between processors continously throughout the ... View full abstract»

    This paper discusses the implementation of two sequential procedures to construct confidence intervals for a simulation estimator of the steady-state mean of a stochastic process. Our quasi-independent-mean (QIM) methods attempt to obtain i.i.d. samples. We show that our sequential procedures give valid confidence intervals. The two assumptions required are that the stochastic-process output seque... View full abstract»

    The next generation of communication networks will simultaneously offer multiple service classes capable of supporting both real-time and best-effort traffic. At the level of an individual network router or gateway, a critical question that needs to be addressed is the development of a set of policies and metrics to determine how router resources should be shared between different service classes....

    Software systems are known to suffer from outages due to transient errors. Recently, the phenomenon of “software aging”, one in which the state of the software system degrades with time, has been reported. To counteract this phenomenon, a proactive approach of fault management, called “software rejuvenation”, has been proposed. This essentially involves gracefully terminati... View full abstract»

    A specification language was defined to outline sections of cities as cell spaces. The goal is to allow the definition of complex traffic models in a simple fashion for the modeler. Once the urban section is outlined, the traffic flow is automatically set up. In this case, the language was expanded to include the behavior of trucks. The models are formally specified, avoiding a high number of erro... View full abstract»

    Air traffic delay is a growing and expensive problem. We looked at ways to reduce the cost and magnitude of such delays by trading gate delays against more expensive air delays. Air management and planning at this level can be facilitated by simulation, especially for strategies that alter controls on the system. We used the SIMMOD air traffic simulation to model the system. Since the model is sto... View full abstract»

    Performance tuning in the embedded systems domain poses a new set of challenges for software and hardware designers. Techniques proven to work for general purpose architectures cannot always be directly applied to the signal processor environment. Program analysis and simulation tools have been shown to be available in the analysis of general purpose microprocessors. We anticipate that similar too... View full abstract»
