This paper considers applying the matching pursuit algorithm with chirplet dictionary for an adaptive time-frequency analysis of the non-stationary magnetic fields. The way of the assessment of the exposure level to low-frequency magnetic field emissions, in reference to admissible levels, proposed by International Commission on Non-Ionizing Radiation Protection, is presented. The selected results of the analysis of the low-frequency magnetic field are presented.

This paper describes an amperometric sensor module for gas concentration measurement. A module can be used for many types of electrochemical gas sensors without major hardware changes. Device is based on AVR ATmega8 microcontroller. As signal processing circuit a specialized integrated circuit LMP9l000 configurable via I2C interface is used. The concept of a measuring system composed of several modules dedicated for a gas sensors array is presented as well. System controls modules, collects and analyses their responses. It was designed with an emphasis on universality and modularity. The proposed equipment will be used as the core of electronic nose system employed for classifying and distinguishing different levels of contamination in air.

The increasing of industrial and civil activities produces changes in the quality of water discharged in land, and in rivers/seas, and surface water. Every activity needs a water treatment plant. The quality of water must be conform to specific technical legislation. In order to control the quality of wastewaters, some efficient techniques are requested especially in presence of solvents and suspended solids. A spectroscopic method is proposed along with a statistical approach for validating data.

The maintenance of secure traffic conditions during winter is ensured by the use of de-icers. The type of de-icers used depends on the surfaces that need to be treated. However, these products can have important impacts provoking corrosion or aging appearance of materials surrounding the surfaces that are treated. In this work, we present a set of tests developped for the evaluation of the de-icer impacts on infrastructure materials, impacts investigated through aging tests.

Wireless sensor networks are nowadays used in many industrial and automotive applications for distributed sensing and instrumentation. This paper presents the design of a dependable wireless sensor node for the application in automotive engine test beds. The sensor node is autonomously powered by means of a solar cell harvester module, which allows for the continuous operation of the sensor even in periods of low ambient light conditions. The measurement module features a Pt1000 based low power evaluation circuitry for temperature monitoring and a circuitry to determine the available input power for energy budget estimation. Experimental results obtained under laboratory conditions and in an automotive testbed are presented to demonstrate the applicability of proposed design.
