Qualitative modelling and analysis of regulations in multi-cellular systems using Petri nets and topological collections [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
In this paper, we aim at modelling and analyzing the regulation processes in multi-cellular biological systems, in particular tissues. The modelling framework is based on interconnected logical regulatory networks a la Rene Thomas equipped with ...

A Decidable Characterization of a Graphical Pi-calculus with Iterators [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
This paper presents the Pi-graphs, a visual paradigm for the modelling and verification of mobile systems. The language is a graphical variant of the Pi-calculus with iterators to express non-terminating behaviors.

Application of Continuous Non-Gaussian Mortality Models with Markov Switchings to Forecast Mortality Rates

open access: yesApplied Sciences, 2022
The ongoing pandemic has resulted in the development of models dealing with the rate of virus spread and the modelling of mortality rates μx,t. A new method of modelling the mortality rates μx,t with different time intervals of higher and lower ...

Towards a Step Semantics for Story-Driven Modelling [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
Graph Transformation (GraTra) provides a formal, declarative means of specifying model transformation. In practice, GraTra rule applications are often programmed via an additional language with which the order of rule applications can be suitably ...

A Data-Driven Methodology for the Simulation of Turbulent Flame Speed across Engine-Relevant Combustion Regimes

open access: yesEnergies, 2021
Turbulent combustion modelling in internal combustion engines (ICEs) is a challenging task. It is commonly synthetized by incorporating the interaction between chemical reactions and turbulent eddies into a unique term, namely turbulent flame speed sT ...

Associating Climatic Trends with Stochastic Modelling of Flow Sequences

open access: yesGeosciences, 2021
Water is essential to all lifeforms including various ecological, geological, hydrological, and climatic processes/activities. With the changing climate, associated El Niño/Southern Oscillation (ENSO) events appear to stimulate highly uncertain patterns ...

Aspects of multiscale modelling in a process algebra for biological systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
We propose a variant of the CCS process algebra with new features aiming at allowing multiscale modelling of biological systems. In the usual semantics of process algebras for modelling biological systems actions are instantaneous.

A Computational Approach to Solve a System of Transcendental Equations with Multi-Functions and Multi-Variables

open access: yesMathematics, 2021
A system of transcendental equations (SoTE) is a set of simultaneous equations containing at least a transcendental function. Solutions involving transcendental equations are often problematic, particularly in the form of a system of equations.
