This work presents a faster method of simulating exactly from a distribution known as a Vervaat perpetuity. A parameter of the Vervaat perpetuity is β ∈ (0,∞). An earlier method for simulating from this distributon ran in time O((2.23β)β). This earlier method utilized dominated coupling from the past that bounded a stochastic process for perpetuities from above. By extending to non-Markovian up...

Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent on/off processes. Several simulation experiments illustrate the use of the perfec...

The building performance simulation community applies theory from several different fields to develop models for heat transfer, light propagation, human behavior, and other domains. To integrate these models, we propose the adoption of general modeling conventions from the less familiar field of modeling and simulation theory. The conventions we explore are known as the Discrete Event System Sp...

This paper deals with the experimental testing and verification of the earlier proposed load balancing and coupling factor criteria for the conservative parallel discrete event simulation in heterogeneous execution environments whether they can ensure a good speedup. The definition of the relative speedup is extended to the heterogeneous systems in a natural way. This definition is used to meas...

Simulation plays an important r^ ole in stochastic geometry and related elds, because all but the simplest random set models tend to be intractable to analysis. Many simulation algorithms deliver (approximate) samples of such random set models, for example by simulating the equilibrium distribution of a Markov chain such as a spatial birth-and-death process. The samples usually fail to be exact...

This study considers using of Component Template Library (CTL) as middle-ware and weak coupling algorithm of software components for heat transfer and structure analysis. The CTL interface is specially designed to exchange data between the software components. The structure simulation component is linked to the heat transfer simulation component by remote method invocation and by dynamic linkag...

In this paper we are concerned with a weak coupling technique for the concurrent simulation of multiscale phenomena. In particular we focus on the construction of an initial embedding of discrete atomic data fields in an appropriate subspace HN (Ω) ⊂ L(Ω) which provides the foundation for the proposed coupling technique in a function space setting. Thus, we must consider the regularity of the c...

A novel microstrip Coupler with Complementary SplitRing Resonator (CSRR) is simulated and fabricated. The CSRR structure in the grounded plane of a conventional microstrip double-line coupler, increases its even mode characteristic impedance. This results in a higher degree of coupling. The results of simulation and measurement show that the new coupler achieves a high degree of coupling (5 dB ...

Inductive and capacitive coupling effects for high-speed global interconnects are studied via simulation. The impact of inductive coupling on delay and noise is found to be comparable to capacitive effects in high-speed buses. The results indicate that current-return paths are not strictly bounded by wide VDD/GND lines, so that inductive coupling is only partially eliminated by using shield wir...
