The paper presents an assessment of the ecological potential of the Soła river based on the benthic macroinvertebrates and diatomaceous phytobenthos, according to the principles of the Water Framework Directive. The calculated values of Multimetric Diatom Index (IO) indicated class II of ecological potential, while the Multimetric Macroinvertebrate Index (MMI_PL) − class III. The final classification of biological, physicochemical and hydromorphological elements showed that the examined section of the Soła river represents a moderate ecological potential which indicates a moderate disruption in the functioning of the water ecosystem as well as a violation of the hydrological regime and morphological conditions of the riverbed.

Recognition of the deteriorating conditions of rivers worldwide has called for increased efforts to improve the ecological quality of impacted river systems. This is particularly important in areas that have suffered from a significant impact of human pressure on the ecological status of water. Field studies were conducted in the Ruda River in an area that had undergone anthropogenic disturbances. The objectives of our survey were to test the biological metrics based on benthic macroinvertebrates at four study sites. Spring and autumn surveys of benthic invertebrates indicated that based on the BMWP and BMWP(PL) indices, water quality was higher in comparison with the value of Multimetric index at all of the sites that were studied. Our results revealed that the water quality was higher at the study sites that are located above the dam reservoir based on both the chemical and biological parameters. This study also indicated that both spring and autumn constitute appropriate periods for carrying out monitoring studies. The values of multimeric index indicated the same water quality (except for site 1) in both sampling periods. Anthropogenic transformations of a riverbed influence the flora and fauna and affect the ecological status of rivers.

W artykule podjęto problematykę wdrażania nowoczesnych technologii w zakresie systemów sterowania ruchem kolejowym. Postęp i rozwój transportu kolejowego nie byłyby możliwe bez wielu nowych rozwiązań w dziedzinie telekomunikacji i sygnalizacji kolejowej. Do takich systemów należą Europejski System Sterowania Pociągiem ETCS (European Train Control System) oraz Globalny System Komunikacji Mobilnej dla Kolei GSM-R (Global System for Mobile Communications - Railways).

Interaction between the driver and transport telematics is the focus of this paper. In its first part, methods of attracting driver’s attention and affecting them were analysed, with the use of feasible information displays. Potential hazards were also investigated. It latter part, research regarding driver attitude towards route planning using in-vehicle telematics was presented.

Przedstawiono nowe projekty interfejsu kontaktu chirurg-telemanipulator oraz sprzętowo-programowe rozwiązania w strukturze systemu sterowania opartego o reprogramowalne układy FPGA, umożliwiające włączenie zadajników do systemu Master-Slave telemanipulatora chirurgicznego Robin Heart. Badane i przedstawione w pracy zostały zadajniki bazujące zarówno na manipulacji za pomocą kończyny górnej, jak i dolnej. W konsoli sterującej systemu, stanowiącej zintegrowany system akwizycji, przetwarzania i wizualizacji sygnałów z podstawowych kanałów komunikacyjnych systemu, przedstawiono również projekt i testy wstępne toru obrazowania przestrzennego 3D dla poprawy jakości pracy chirurga. Opisano wykorzystanie przygotowanych interfejsów i systemu sterowania w eksperymentach na zwierzętach, telemanipulacji na duże odległości oraz w przygotowaniach do pierwszego testu klinicznego dla telemanipulatora toru wizyjnego Robin Heart.

New construction of Man-Machine Interfaces, 3D vision channel and control system structure of Robin Heart surgery telemanipulator are presented. Input module of control system work on the base of reprogrammable FPGA chip, which revealed to be an universal and elastic solution for different types of sensors in Master tool. New Master/Operator devices make possibile to use both upper and lower limb to control the robotnic arm. Prepared system was tested on several animal experiments and long distance teleoperation.
