During the last years, scenarios, use-cases and other techniques for modelling the global behaviour have been introduced into object-oriented analysis. However, aggregation and generalisation of scenarios as well as the integration of scenarios reflecting ...
Subjected to moisture variations under a long-time mechanical loading, wood shows a delayed behaviour, where the total response is not the simple accumulation of those corresponding to the mechanical loading and the zero-load swelling-shrinkage deformation ...
Most software development methods define notations for modelling global behaviour. Many of these notations use interaction diagrams to model possible sequences of interactions between a system and its environment, or between the objects of the system. Othe ...
This thesis investigates the concepts commonly used for modelling global behaviour in object-oriented analysis methods (use cases, interaction diagrams, scenarios, scripts etc.). It describes some common drawbacks of current approaches (e.g. assumption of ...
We present a numerical study of the electrostatic wobble motor. Both finite- element calculations and analytical approaches are used to calculate the torque exerted by the electrodes. Both methods give very similar results, validating an analytical approac ...
We studied the formation of buried heterostructures obtained in a single growth step over nonplanar substrates patterned with ridges. When the ridge dimensions are large enough, the growth on the mesa top is similar to that on a planar substrate. In contra ...
This paper reports the results of specifying and verifying the steam boiler problem with Promela/SPIN. Several models of the system have been produced with different degrees of completeness. Each model represents an abstract level for capturing the origina ...
The temperature dependence of the critical current density has been studied in magnetic fields up to 12 T for Bi-2212/Ag round wires. In short specimens critical current densities of more than 10000 A/cm(2) have been achieved at 20 K and B = 8 T. In the ca ...
The purpose of this work is to predict the behaviour of electric devices using superconducting tapes, including the transition of those tapes to the normal state, which implies a typical non linear behaviour. The frequency domain studied is as wide as poss ...
An innovative way of animating actors at a high level based on the concept of synthetic vision is presented. The objective is simple: to create an animation involving a synthetic actor automatically moving in a corridor avoiding objects and other synthetic ...
