Abstract Several applications in the scientific simulation of physical systems can be formulated as control/optimization problems. The computational models for such generally contain hyperparameters, which control solution fidelity and expense. tuning these parameters is non-trivial general approach to manually ‘spot-check’ good combinations. This because optimal hyperparameter configuration se...

Grid Infrastructure and popular Grid computing toolkit Globus Toolkit 3.0(GT3) are introduced in this paper. A distributed simulation system based on Grid computing is developed, working mechanism and architecture model of this system are also discussed in this paper. Simultaneously, a distributed simulation experimentation about lightning electromagnetic field is implemented in Grid computing ...

adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

Recent advances in Service Oriented Architecture (SOA) provides many exciting opportunities for developing nextgeneration of distributed simulation frameworks and tools. At the mean time, Peer-to-Peer (P2P) based network technique also challenges the traditional view of distributed simulations. Indeed, the integration of SOA and P2P techniques can potentially help on developing more flexible, s...

In this paper, the synchronization of a new hyperchaotic complex system based on T-S fuzzy model is proposed. First, the considered hyperchaotic system is represented by T-S fuzzy model equivalently. Then, by using the parallel distributed compensation (PDC) method and by applying linear system theory and exact linearization (EL) technique, a fuzzy controller is designed to realize the synchron...

This paper focuses on a Bayes inference model for a simple step-stress life test using Type-I censored sample in a discrete set-up. Assuming the failure times at each stress level are geometrically distributed, the Bayes estimation problem of the parameters of interest is investigated in the both of point and interval approaches. To derive the Bayesian point estimators, some various balanced lo...

We present a study of the notion of coalgebraic simulation introduced by Hughes and Jacobs. Although in their original paper they allow any functorial order in their definition of coalgebraic simulation, for the simulation relations to have good properties they focus their attention on functors with orders which are strongly stable. This guarantees a so-called “composition-preserving” property ...

Real-time, human-in-the-loop simulation of air traffic control is naturally distributed across computing platforms because of the need for many input and display devices, the need for computing power, and the need to integrate legacy simulations that run on a variety of platforms. Object orientation has a long history of fruitful application to simulation problems, including real-time simulatio...
