I present some simple reasoning about creative behaviour based on a framework derived from the work of Boden [Boden, 1990; 1994]. The aim is to move further towards a model which allows detailed comparison, and hence understanding, of systems which exhibit behaviour which would be called “creative” in humans. The work paves the way for the description ofmore natural, multi-agent creative AI sys...

It is well known that, asymptotically, the appropriately normalized uniform Vervaat process, i.e., the integrated uniform Bahadur–Kiefer process properly normalized, behaves like the square of the uniform empirical process. We give a complete description of the strong and weak asymptotic behaviour in sup-norm of this representation of the Vervaat process and, likewise, we study also its pointwi...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

This paper presents the complete algorithm of site response analysis of nonhomogeneous topographic structures using transient two-dimensional boundary element method (BEM). Seismic behaviour of various topographic features including canyon, half plane, sedimentary filled valley and ridge sections, subjected to incident SV and P waves are analysed. The analysis shows the efficiency of the propos...

FPGA-based synthesis tools require information about behaviour and architectural to make effective use of the limited number of cells typically available. A hardware description language which models layout and behaviour is used to elegantly specify circuit architecture. This source level information is used to efficiently translate circuit descriptions onto FPGA devices.

We give a nontechnical description of the behaviour of dynamical systems governed by two distinct time scales. We discuss in particular memory effects, such as bifurcation delay and hysteresis, and comment the scaling behaviour of hysteresis cycles. These properties are illustrated on a few simple examples.

In this paper we present our contribution in the domain of real-time system design. This approach is twofold: an UML2.0 and SysML-based architecture description including functional and structural specification, resource allocations and QoS modelling; a quantitative analysis with formal description of behaviour using Time Petri Net. The quantitative analysis explores the solution space and prov...

During the development of communication systems, the languages MSC and SDL are used for the standardisation, development and implementation of protocols. Both languages are an essential part of today’s popular development methodologies with the UML language. In MSC specifications, the system is described by examples while in SDL specifications it is described completely by means of communicatin...

Robots, which are able to carry out their tasks robustly in real world environments, are not only desirable but necessary if we want them to be more welcome for a wider audience. But very often they may fail to execute their actions successfully because of insufficient information about behaviour of objects used in the actions. In this article we propose an approach to avoid the unsuccessful co...

Description-driven systems based on meta-objects are an increasingly popular way to handle complexity in large-scale objectoriented database applications. Such systems facilitate the management of large amounts of data and provide a means to avoid database schema evolution in many settings. Unfortunately, the description-driven approach leads to a loss of simplicity of the schema, and additiona...
