Opis:
The paper presents a speech emotion recognition system for social robots. Emotions are recognised using global acoustic features of the speech. The system implements the speech parameters calculation, features extraction, features selection and classification. All these phases are described. The system was verified using the two emotional speech databases: Polish and German. Perspectives for using such system in the social robots are presented.

Opis:
This study is devoted to the modeling and control of a 4-wheel, skid-steering mobile platform with coupled side wheels, subject to lateral and longitudinal slips. The dynamics equations of the platform are derived, and 16 variants of motion distinguished. For the variant of motion allowing for all possible slips of the wheels two control problems are addressed: the motion planning problem and the trajectory tracking problem. The former problem is solved by means of a Jacobian motion planning algorithm based on the Endogenous Configuration Space Approach and, complementarily, using the Optimal Control Approach. The Nonlinear Model Predictive Control is applied to the latter problem. Performance of these control algorithms is illustrated by a sort of the parking problem. Significant robustness of the predictive control algorithm against the model uncertainty is revealed.

Opis:
A key element in ensuring the safety of the port of Świnoujście against oil spills is to ensure combat units are properly equipped with oil spill collecting equipment, and that they have the ability to effectively use the existing resources. All of this should be properly reflected in the port’s contingency plans. It is also important to develop tactics for oil spill combat action that take into account both local conditions and worst case scenarios with parallel checking of these scenarios during the exercise and the table-top exercises. The use of computer simulation to forecast oil spill behaviour allows for better arrangement and more efficient use of resources and the optimum development of antipollution action and tactics. The specific location of the Świnoujście harbour, its breakwaters shape, and that shipping traffic is allowed only on the approaching waterway, may lead one to the conclusion that the port of Świnoujście is completely safe from any possible petroleum pollution after a ships’ collision and the antipollution action should focus only on maximising the protection of the coast. To verify this assumption, simulations of an oil spill spreading after a vessels’ collision were carried out. The purpose of the simulations was to determine the most unfavourable weather conditions which would lead to the port of Świnoujście being polluted, and to define the best tactics for conducting oil spill combat actions under such conditions. The simulations clearly indicated that, with a particular combination of weather conditions, pollution could occur inside the port. It could result in vessel traffic suspension and huge financial losses. Simulations were conducted using the PISCES II oil spill simulator.

Opis:
According to the HELCOM AIS, there are about 2,000 ships in the Baltic marine area at any given moment. The main environmental effects of shipping and other activities at sea include air pollution, illegal deliberate and accidental discharges of oil, hazardous substances and other wastes, and the unintentional introduction of invasive alien organisms via ships’ ballast water or hulls. Original oil pollution model and optimal allocation of response resources was proposed in the paper.
