Endurance Time method is a time history dynamic analysis in which structures are subjected to increasing excitations. These excitations are known as endurance time excitation functions (ETEF). This study proposes a new method for generating ETEFs. In the proposed method, a new basis function for representing ETEFs is introduced. This type of ETEFs representation creates an intelligent space for...

An optimal configuration method of simulation parameters, including the solver and step size each sub-model, is proposed to realize real-time virtual simulation. The content presented study threefold: firstly, requirements three modes, Model-Exchange, Co-Simulation, Hybrid are analyzed; secondly, mathematical descriptions problems constructed, which classified as an inequality problem two assig...

in recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. the core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

in this paper, we consider a stochastic time-cost tradeoff problem (tctp) in pert networks for project management, in which all activities are subjected to a linear cost function and assumed to be exponentially distributed. the aim of this problem is to maximize the project completion probability with a pre-known deadline to a predefined probability such that the required additional cost is min...

On-line simulations play a critical role in understanding, supervising, and controlling large-scale systems. For instance, in military training applications, users are presented with complex scenarios that consist of both actual and simulated devices interacting in real-time. Troubleshooting of complex telephone networks may utilize on-line simulations to play`what if' games when evaluating alt...

This paper presents and discusses some methods used for simulation of fluids and highly deformable bodies. Two main approaches are compared, advantages and disadvantages of these methods are evaluated with reference to their possible use in real-time. Simulations of fluid volumes are considered as opposed to the frequently used approach that just use surface simulations.

In classical parallel discrete-event simulation, the simulation state space is decomposed into a number of sub-spaces. The responsibility for the simulation of each sub-space is assigned to a separate parallel process and simulation is performed concurrently by the parallel processes. This is also referred to as spatial parallelization. To allow for an efficient parallel simulation, a suitable ...

This article will show a new method to simulate specifications of real-time communicating systems, by using process execution trees. These self-transforming structures can be translated to e.g. C++ and allow simulations, synchronised with the real world time. Simulating specifications with process execution trees is discussed for the well-known process algebra CCS. The described method of proce...

We present a survey of some recent techniques that allow a significant reduction in simulation time, namely statistical simulation, sampled simulation or reduced input benchmarks. We also note that these techniques are not useful in analysing memory systems. Thus, we provide a study of analytical memory models that have been used to model cache performance.

The field of cloth-modeling has been widely investigated during the last decade. Many solutions have been proposed for the different aspects related to that field, ranging from fast cloth integration methods to complex collision handling. However, it is still challenging to perform simulations in real-time without compromise. In this thesis, we base our work on fast collision detection methods ...
