in this paper, the radial breathing mode (rbm) frequencies of multi-walled carbon nanotubes (mwcnts) are obtained based on the multiple-elastic thin shell model. for this purpose, mwcnt is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der waals (vdw) forces between two adjacent tubes. lennard-jones potential is used to calculate the vdw forc...
As the demand for domainand formalism-specific visual modelling environments grows, the need to rapidly construct complex User Interfaces (UIs) increases. In this paper, we propose a Multi-Paradigm Modelling (MPM) approach whereby structure, visual appearance and above all reactive behaviour of a UI are explicitly modelled. These models are constructed at the most appropriate level of abstracti...
There have been significant advances in consequence modelling of releases of hazardous materials in the last decade, but the use of simple models for predicting overpressures from vapour cloud explosions (VCEs) continues to elude safety practitioners. The TNO multi-energy model has generally been regarded as the best model available to date, for a rapid assessment of explosion overpressures and...
abstract This paper gives an overview of the modelling and simulation system MIMOSE, which consists of a model description language and an experimental frame for the simulation of models. The main purpose of the MIMOSE project was the development of a modelling language which considers special demands of modelling in social science, especially the description of nonlinear, quantitative and qual...
Cross-classified and Multiple Membership Structures in Multilevel Models: An Introduction and Review
This review provides an introduction to the role of statistical modelling of complex social situations, in particular considering the application of advanced methodologies to an educational context. By building an overview of techniques such as cross classified multi-level modelling and multiple membership structures and through a comprehensive review of the application of these techniques the ...
This paper presents an extension of an algebra of high-level Petri nets with operations for suspension and abortion. These operations are sound with respect to the semantics of preemption, and can be applied to the modelling of the semantics of highlevel parallel programming languages with preemption-related features. As an illustration, the paper gives an application to the modelling of a mult...
To understand the function of genetic regulatory networks in the development of cellular systems, we must not only realise the individual network entities, but also the manner by which they interact. Multi-valued networks are a promising qualitative approach for modelling such genetic regulatory networks, however, at present they have limited formal analysis techniques and tools. We present a f...
