In the case of unforeseen obstacles, the nominal trajectory of articulated vehicle has to be modified, in order to avoid collisions. The paper presents comparison of dynamic optimisation methods used to calculate optimal braking torques applied to wheels of an articulated vehicle in lane following/changing manoeuvre in order to prevent vehicle before(More)
The paper presents an application of neural networks to control braking torques on wheels of an articulated vehicle in an untripped rollover manoeuvre. The numerical model of the articulated vehicle and dynamic optimisation were used to calculate appropriate braking torques for each wheel in order to restore stability. The optimisation problem requires the(More)
In many cases, solving optimisation problems, in particular a dynamic optimisation problem, is time-consuming. This is due to the long time of calculation of the objective function value. For example, during optimisation of the articulated vehicle it is necessary to integrate dynamic equations of motion in the whole time interval. The paper presents an(More)
This paper presents a data mining technique for qualitative analysis of Hodgkin-Huxley model of cell excitability. Such problem cannot be solved analytically. Therefore we apply Monte-Carlo techniques for the generation of model parameters, and use data mining algorithm for classification of learning tuples obtained. As a result we attain a decision tree(More)
The paper presents a method for determining optimal courses of drive functions which are applied during a satellite orientation change manoeuvre. This task was realized in two steps. First, a series of simulations was performed, during which the optimisation problem has been solved using the Nelder-Mead algorithm. Dynamic optimisation results are optimal(More)
This paper presents a software package developed for the simulation of spatial mechanisms with both rigid and flexible links. In order to formulate the equations of motion of the system joint coordinates and homogenous transformation are used. Flexible links are discretised by means of the Rigid Finite Element Method (RFEM). In the paper the implementation(More)
The known information security assessment risk system (developed by authors) is based on processing methods of linguistic variables. Their foundation are reference parametric trapezoidal fuzzy numbers with different plurality of defining terms, the formation of which is associated with the involvement of experts in the relevant subject area.
