چکیده

ieniveauworden deze twee soorten gedrag uniform behandeld, als normale el-ementen van de procesalgebra. Hun gedragwordt bepaald door gebruik temaken vanstructural operational semantics (SOS) regels [Plotkin, 1981, 2003]. Verder respecterende regels al de verschillen tussen trajectory prefixes en action prefixes, gebaseerd oponze intuïtie over hoe dergelijke processen zich zouden moeten gedragen. Bijvoor-beeld, in parallelle compositie moeten de trajectory prefixes altijd synchroniseren,terwijl voor action prefixes interleaving semantics wordt gebruikt. Verder definiërenwe een hybride sterke bisimulatierelatie voor BHPC en bewijzen dat het een con-gruentie is. Het is een van de belangrijkste eigenschappen om een goed bepaaldecompositionaliteit te bereiken. Zo’n eigenschap staat het toe om bisimilaire processenom te wisselen binnen elke expressie in de procesalgebra. Met andere woorden, hetstaat toe om processen te verfijnen, hun interne representatie te veranderen, en henom te wisselen zonder enig verlies, zolang ze hetzelfde gedrag vertonen.We introduceren een techniek voor simulatie van BHPC. We construeren eensimulatiealgoritme voor een deelverzameling van BHPC-operatoren en testen enkelevoorgestelde technieken in het B prototype. Het voorgestelde simulatiealgoritmebepaalt een van de mogelijke manieren om de Behavioural Hybrid Process Calculuste simuleren. Verder onderzoeken we de belangrijkste problemen in simulatie vanhybride systemen in het licht van BHPC en in een meer algemene opzet. Voor enkelekwesties stellen we oplossingen voor, voor de overgebleven vraagstukken besprekenwe mogelijke manieren om de problemen aan te pakken.

Which Methodology is Better for Combining Linear and Nonlinear Models for Time Series Forecasting?

Both theoretical and empirical findings have suggested that combining different models can be an effective way to improve the predictive performance of each individual model. It is especially occurred when the models in the ensemble are quite different. Hybrid techniques that decompose a time series into its linear and nonlinear components are one of the most important kinds of the hybrid model...

A hybridization of evolutionary fuzzy systems and ant Colony optimization for intrusion detection

A hybrid approach for intrusion detection in computer networks is presented in this paper. The proposed approach combines an evolutionary-based fuzzy system with an Ant Colony Optimization procedure to generate high-quality fuzzy-classification rules. We applied our hybrid learning approach to network security and validated it using the DARPA KDD-Cup99 benchmark data set. The results indicate t...

Soft Switching MBC Controller for MIMO Linear Hybrid Systems

Switching supervisory is the most important section of a feedback control process inMIMO hybrid systems. By choosing a non-compatible controller, system may go tounstable mode or high overshoot response. In this paper, a new method of switchingfor selecting MBC controllers is discussed. Results of the simulation show the MIMO(2-in 2-out) linear hybrid system can be switched stable and low overs...

Constrained Nonlinear Optimal Control via a Hybrid BA-SD

The non-convex behavior presented by nonlinear systems limits the application of classical optimization techniques to solve optimal control problems for these kinds of systems. This paper proposes a hybrid algorithm, namely BA-SD, by combining Bee algorithm (BA) with steepest descent (SD) method for numerically solving nonlinear optimal control (NOC) problems. The proposed algorithm includes th...

Stability analysis of nonlinear hybrid delayed systems described by impulsive fuzzy differential equations

In this paper we introduce some stability criteria of nonlinear hybrid systems with time delay described by impulsive hybrid fuzzy system of differential equations. Firstly, a comparison principle for fuzzy differential system based on a notion of upper quasi-monotone nondecreasing is presented. Here, for stability analysis of fuzzy dynamical systems, vector Lyapunov-like functions are defined....
