Event Scheduling in Simulation of Discrete Event Systems with Application on Queuing Systems. [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2010
Queuing theory and other of discrete and continuous event systems have theory aesthetic but the more assumptions which indepent these theories are not accurate as compared with real situation, also the queue problem is one of the most scientific problems

Combining discrete and continuous simulation dynamo into simscript [PDF]

open access: yesProceedings of the 7th conference on Winter simulation - WSC '74, 1974
Discrete and continuous simulation can be combined in one program by using a discrete simulation language to simulate, among other things, a continuous simulation program. This amounts to the translation of the continuous language into the discrete language. The translation of Dynamo into Simscript is examined.

A comparison of mixed-variables Bayesian optimization approaches

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Most real optimization problems are defined over a mixed search space where the variables are both discrete and continuous. In engineering applications, the objective function is typically calculated with a numerically costly black-box simulation ...

A Discrete-Time State Estimation for Nonlinear Systems With Noises

open access: yesIEEE Access, 2020
This paper proposes a discrete-time observer to estimate states of continuous-time nonlinear systems with presences of noises. Most conventional discrete-time state observers are designed using discrete-time models, which are derived by applying the ...

An Impulse-Quantizing Synchronization Approach for Mixed Continuous-Discrete Complex Networks

open access: yesDiscrete Dynamics in Nature and Society, 2023
This paper presents synchronization of mixed continuous-discrete complex network via impulse-quantizing approach. A delay-partitioning group strategy is proposed and impulse-quantizing control is designed to derive theoretical criteria ensuring scale ...

Simulating continuous symmetry models with discrete ones

open access: yesPhysical Review B, 2022
Especially in one dimension, models with discrete and continuous symmetries display different physical properties, starting from the existence of long-range order. In this work, we that, by adding topological frustration, an antiferromagnetic $XYZ$ spin chain, characterized by a discrete local symmetry, develops a region in parameter space which mimics
