The Timer Cascade: Functional Modelling and Real Time Calculi
Case studies can significantly contribute towards improving the understanding of formalisms and thereby to their applicability in practice. One such case, namely a cascade of the familiar 24-hour timers (in suitably generalized form) provides interesting gedanken experiments and illustrations for presenting, illustrating and comparing various formalisms for modelling real-time behaviour of syst...
متن کاملApplication of Bhave Toolset for System Control and Electronic System Design
Behavioural Hybrid Process Calculus (BHPC) is a formalism for modelling and analysis of hybrid systems combining process algebras and the behavioural approach for modelling of instantaneous changes and continuous evolution. BHPC is supported by Bhave toolset, containing a tool for a novel way of visualisation of hybrid systems simulations msp-svg and a new version of hybrid simulator. We presen...
متن کاملA new hybrid modeling methodology based on delayed differential equations: Application to antibody expression by Pichia pastoris
In this paper a novel methodology for biosystems dynamic modelling is presented in which discrete time series, namely AutoRegressive (eXogenous) models are incorporated in the traditional parametric/nonparametric hybrid modelling framework. This results in a set of Delay Differential Equations (DDE) which describe the material balances of a bioreactor system in which dynamic kinetics are mimick...
متن کاملA compositional modelling and analysis framework for stochastic hybrid systems
The theory of hybrid systems is well-established as a model for real-world systems consisting of continuous behaviour and discrete control. In practice, the behaviour of such systems is also subject to uncertainties, such as measurement errors, or is controlled by randomised algorithms. These aspects can be modelled and analysed using stochastic hybrid systems. In this paper, we present HMODEST...
متن کاملModelling and Investigating the Differences and Similarities in the Volatility of the Stocks Return in Tehran Stock Exchange Using the Hybrid Model PANEL-GARCH
Efficient financial markets with high degree of transparency do not substantiate the hypothesis that there are differences in the volatility of return. Generally, there are factors rejecting any perfect similarity in the volatility of return in the emerging stock markets, as previous studies in Iran have confirmed the complete difference. On the other hand, the hybrid model PANEL-GARCH has the ...
متن کاملPredicting the Structural Performance of Heat-Treatable Al-Alloys
Advances in physically-based and adaptive numeric modelling (ANM) have lead to a significant elevation of the role of modelling in commercial alloy development and process optimisation. Within these two categories of modelling a wide variety of techniques exists, whilst hybrid approaches, taking advantage of the benefits of the both methods, are also being developed. In this paper various ANM t...
