The paper concerns a measurement setup prepared for the collection of measurements of coils with ferromagnetic cores. The measurements are collected through a DAQ (data acquisition) device, while the input voltage is supplied by an arbitrary function generator. All this is controlled from a computer running a special program written in C#. The program applies an algorithm which allows to obtain the impedance for each selected frequency. Three ferromagnetic coils are studied, for which the frequency characteristics are obtained. For the studied coils — simple models are proposed, which consist of fractional circuit elements (fractional coils and fractional capacitors).

In this paper an idea of an open system for electrical capacitance tomography with LabVIEW interface is presented. The EVT4 multi-channel data acquisition hardware is a main part of the system. This device offers a high signal to noise ratio of capacitance measurement and a high frame rate even for a 32 electrode sensor. The developed LabVIEW interface covers the entire functionality of the EVT4 communication protocol and implements multi-threading. The users can create own software dedicated to a given application. The elaborated open system allows working with sensors of various electrode configurations and different excitation cycle. The application of LabVIEW interface should facilitate the compilation of the measurement setup using not only the EVT4 hardware but also additional devices used in the experiment.

The paper presents a parallel computing algorithm with its implementation in software for diagnostic of line start permanent magnet synchronous motor (LSPMSM). The software based on the developed algorithm, allows for analysis using a discrete Fourier transform (DFT) or a discrete wavelet transform (DWT). The elaborated software was tested using the phase current of the LSPMSM. In the case of wavelet analysis, the input signal refers to start-up of the motor supplied with symmetrical voltage, without external load, while steady-state waveforms were used for the DFT analysis. Moreover, the mentioned software has an implemented multi-layer perceptron neural network which can be used as decision element of the diagnostic system. In addition, the article brought closer the issues related to the structure and learning algorithms of artificial neural networks and OpenCL framework.

This paper presents Industry 4.0 approach to design of mechatronic systems with focus on control system development as well as process data acquisition and its further availability across different domains. Classical approaches utilize waterfall methodology for design and implementation of control software in mechatronic devices [1], while in the proposed article a workflow V-model is applied. Comprehensive information about the system topology and its nonlinear model is included. The system architecture was summarized with the use of SysML notation. Finally, the methodology was implemented to conduct a series of experiments on a mechatronic feed drive; results of these conducted tests are also shown. The presented approach is compliant with requirements derived for Industry 4.0 paradigm [2].

In the paper we conduct a numerical experiment to check, if it possible to fix parameters of the model with fractional difference operator of variable-order. We investigate discrete-time fractional operator with variable-order of convolution type. We work with fitting the constant coefficients of an equation and the parameters of considered class of order function. We use Iscurvefit routine from Matlab program to get the optimal values of these parameters, which minimise mean squared error between experimental (simulated) data and data given from the theoretical model.

The aim of this paper is to show the potential of the X-ray tomography to measure three-dimensional concentration changes of granular material during concentric and eccentric silo discharging modes. In addition, the X-ray tomography data allows studying the evolution and size of the stagnant zone in the case of funnel flow along the entire cross-sectional area of the silo depth. This study shows that the 3D X-ray tomography data can bring an insight investigation on the density distribution across the entire cross-sectional area of a silo.

The aeration is one of the major processes in water treatment. The aeration process increases oxygen level in water and at the same time treats the water, for example from carbon dioxide or hydrogen sulfide. The main aim of aeration is to improve the quality of water like the smell and taste. The chloroform is one of trihalomethanes. The occurrence this chemical compound has the highest percentage among the rest of trihalomethanes. Moreover, trihalomethanes are formed in disinfected water while the chlorine compounds are used for the process. Trihalomethanes have a negative impact on human health because they are carcinogenic and mutagenic. The purpose of the following publication is to present the effect of aeration on the removal of chloroform from water. The results of research and the analysis showed that the used aeration process remove chloroform from water. The research included various period of aeration and concentrations chloroform in water.

In engineering it is a common practice to apply a mathematical model of a given system in order to describe the behaviour of the system. The main aim of this study is to create a mathematical model of a photovoltaic installation as well as to verify whether such model enables one to assess the effectiveness, operating specification and voltage characteristics of the mentioned installation without the need for creating a real-world working installation. The mathematical models have been prepared for a single photovoltaic cell as well as a series circuit of a couple of cells connected using both a bypass diode. The study has been carried out using Matlab Simulink software in various levels of exposure to Sun rays, various temperatures as well as during a simulation of a partial eclipse of the photovoltaic installation. In order to depict the operation of the mathematical model, a graphic interpretation of the results has been created. The graphic presentation of the data has enabled one to show how temperature and sun-light intensity (changing atmospheric conditions) can influence the voltage characteristics of the photovoltaic modules. It also shows the dependence between power and voltage. The study shows that the mathematical model can be used for exploring anomalies as well as for diagnostics. It also enables one to interpret the results described through an implemented algorithm in a way that would mirror real operating conditions.

In the paper an analysis of the fractional-order backward difference and linear time-invariant difference equations based on the mentioned difference is considered. The analysis is focused on a solution realized by a microcontroller. The problem of the so called “calculation tail” is analyzed. The solutions are compared with these obtained in Matlab. The considerations are important in the context of the fractional-order PID controller real-time implementation.
