An article presents the results of research related to the detection of emotions using combined analysis of galvanic skin response (GSR) and electroencephalographic (EEG) signals. Twenty seven volunteers participated in the experiment. Emotions were evoked by presentation of a set of twenty one movies. Emotions, evoked by individual movies, were later rated by participants according to valence and arousal. GSR signal was used to indicate the most stimulating movies, then features extracted from EEG signal were used to classify emotions. To determine the features EEG signal was analyzed in the frequency domain using fast Fourier transform (FFT) algorithm. For classifying emotions, according to valence and arousal, two classifiers were implemented: support vector machine (SVM) and k-nearest neighbors (k-NN).

The paper consists of well-known Fourier Transform algorithms review with its optimization methods. Beyond others, root of unity lookup table, in-situ computing, bit-reversal permutation, feed forward method and metaprogramming approaches can be pointed out. The main aim of the presented work was to increase currently achieved Short-Time Fourier Transform (STFT) performance using Java programming language. Authors present a new iterative approach. The idea of the solution was to reduce unnecessary operations, by extracting computation and maintenance of loops' indices and twiddle factors' computation as well as reordering output data to the meta-program execution phase, in order to gain strict runtime execution. Presented methods are successfully adapted to electrical capacitance tomography images processing.

Very strict requirements referring to emission standards, the pollution of which is closely related to the quality of the combustion process, forces the manufacturers to introduce new solutions in the field of fuel injection, as well as adapt existing to more stringent standards. A noticeable trend in self-ignition engines is the return to injectors with electromagnetic control, due to the longer durability of the control element in relation to injectors with piezoelectric control. The use of electromagnetic injectors, however, required the introduction of numerous changes, resulting in a reduction in the number and weight of moving elements, which allowed to achieve greater precision of control and multiplication of the fuel dose. Due to the wide range of injector work pressures, it is necessary to determine the delay between the coil override and the beginning of the injection process, so that it is possible to precisely control the supply of fuel at each point of the engine's operation. In order to characterize the delay as a function of fuel pressure, the authors used the photoelectric effect. At the moment when the fuel stream interrupts the light source in the photoactive element, there is a voltage drop, on the basis of which it is possible to determine the actual start of the injection. The authors managed to show that the increase in fuel pressure in the reservoir significantly reduces the response time of the injector. Using the waveform curves, the relationship between the increase in the fuel dose for the measured cross section and the voltage drop in the photoactive element was also determined. It was also found, that the method basing on the use of a radiation source and a photoactive element can be used in the diagnostics of injectors to identify damaged friction pairs needle — body.

The major purpose of power system is to ensure continuous and infallible power supply. In the face of real threat of widespread power system failures which affected numerous power systems, there is a necessity of preparing projects for power system defense and restoration. The defense of power system considers the possibility of failure dodging and, in the case of its occurrence, the limitation of failure range and consequently, return to normal conditions. In turn, successful restoration of power system is connected with generation capacity reconstruction and in the result, power supply of the final consignees. The imminence of power system failures stems from its various triggers, such as atmospheric phenomena, human factors and technical malfunctions thus widespread catastrophic failures of power system constitute a real threat not only to electrical power system, but also to widely understood safety. The development of system failure is a cascading process that is highly sensitive to disturbances in the performance of the power system. The paper contains a review with a statistical analysis of recent large power system failures with particular attention to major blackout causes. The paper also delineates cascading nature of power system failures by indicating the failure stages on the examples of the large blackouts in power systems.

The article presents a comparative analysis of harmful compounds: carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) emitted from vehicles of the passenger car and non-road categories. The research object representing the first category was a vehicle equipped with a Euro 5 compliant compression ignition engine with a common rail fuel injection system. The second one was represented by an agricultural tractor with a compression ignition engine. The tests were carried out in real operating conditions in the Poznan agglomeration. In the case of the passenger car, a real drive was carried out, including passengers, on roads with different speed limits in accordance with the RDE procedure, as adopted in 2017. However, the farm tractor was tested while conducting field work. The tests were carried out using analyzers from the PEMS (Portable Emission Measurement System) group. In order to perform a comparative analysis of vehicles from two separate categories, the results obtained were presented in the form of unit emissions (g/kWh). This paper was aimed at assessing the emissivity of a non-road vehicles and relate them to results obtained from passenger cars. Moreover, the current legislation, tightening the provisions of the increasingly numerous non-road vehicles group has also been assessed.

Sinusoidal modulation techniques are highly applied in the power electronics converters technology and generate harmonic distortion in the load side. The harmonic components generate many problems such as interference with control signals. This paper presents the study results of the carrier based, sinusoidal, modulation method performed for the three-phase, three-wire voltage source inverter. As a result of the carrier based modulation strategy, the output voltage higher harmonics components in the spectrum are observed. They are connected with a carrier signal and with other harmonics sources, e.g. non-linearity load. Using the fluctuation of the switching frequency in the digital modulation system the higher harmonic components of the inverter output voltage can be actively limited. Presented results of the carrier base modulation strategy with the switching frequency fluctuation are selected issues of the control system with the use of a FPGA device. The amplitudes of the output voltage frequency components are reduced in the system with the linear fluctuation of the switching frequency and in the system with the sinusoidal fluctuation of the switching frequency. The results of the sinusoidal modulation method with two kinds of the switching frequency fluctuation used in the voltage source inverter were analyzed and compared.

Determining the location of mobile objects is one of the most basic problems of technology. Selecting the appropriate measurement method depends on the characteristics of the object. A new radio system RSOL (Radio System of Object Location) was proposed. The system operation is based only on its own signals and information which help to work for itself and protect against defects of the GPS or mobile phone system. The part of the system that determines the direction is presented. Proposed device include a locating module and localized module. The system works using the directional radiation pattern of the antenna and making measurements in the input radio track. The measurement determines the direction in which is the locating module relative to the locator. A prototype of the device was designed. Moreover, the results of experiments are presented.

Feeding a microstrip stress sensor using a microstrip line is very common, due to simplicity, ease of production and integration with electronics. In this paper the influence of deformation on microstrip line (ML) feeding microwave strain sensor was studied. This analysis is important for the design and reliability of strain measurement using a microstrip sensor. Finite element method (FEM) was utilized to study this issue. Numerical model in Comsol Multiphysics environment was built and applied for analysis of scattering parameters S11 and S21 change caused by parallel and perpendicular deformation.
