This paper discusses the search for images based on their content. Measuring visual similarity between two or more instances is a fundamental task of computer vision. For a person, evaluating the similarity of images is a natural task. However, in computer vision this is a complex problem that arises mainly due to the semantic gap. This paper discusses the use of a neural network, which allows you to get an estimate of the similarity between a pair of visual representations extracted from input data. The difference between the hashes of the two images obtained at the output of the neural network allows us to evaluate their similarity. The results of the developed algorithm and its software implementation are compared with existing solutions and show the best result on various data sets.

Ultrasonic and optical measurements are used to investigate structural changes in liquid crystal (LC) doped with magnetic Fe3O4 nanorods. These are dispersed in the host in various concentrations. Such structural changes are observed under applied electric and magnetic fields. The investigation methods include acoustic attenuation measurements of surface acoustic waves (SAW) and optical transmission measurements using a laser light beam with linear polarization (532 nm) propagating through the sample. These methods are utilized to understand the system response on the applied external field (increasing/decreasing application) as well as change after step change. Experimental data obtained from both methods are compared to show supplementary effectivity of measurements, the stability of the suspension, and switching behavior.

This paper deals with a painting process in a car company, focused on selection, obtaining and preparation of the data required for data mining analysis. The painting process is a very complex one with various parts, producing huge volumes of data, which are not only heterogenous, but oftentimes not at all time-synchronised and/or missing a common identificator. Thence, the data acquisition part is crucial in the analysis process, and is required to be well-thoughtout and documented. The first part of the paper introduces applications of big data analysis methods in general and with focus on industry, followed by a description of the selected process in the real company and identification of the goal of desired analysis. The second part focuses on acquisition of the required data, therefore proposes the various data sources within the company, the selection process, obtaining of the data (samples or, preferably, in real time), and integration of the obtained. The third part proposes a model for pre-processing and transformation process, with closer look upon the problems and issues specific for such heterogenous data volume. The fourth, final part summarises the results of data preparation and drafts the further analysis of the process.

Energy efficiency of water pumping systems is an issue that has recently been addressed by many authors. Complexity of this issue involves the need to combine energy efficiency of two separate systems which interact with each other: a water supply system and a power system. This paper presents a new non-intrusive method for calculation the efficiency of a squirrel-cage induction motor that is part of a pump unit. The pump control system determines operation of the pumping station operation point and hence its efficiency. It is assumed that there is a generalized estimated characteristic of the motor efficiency, which being a component of the control system, will be used for selection of the pumping system rotational speed change range. Rotational speed has a direct impact on the motor load torque, the pump output and the head, hence, the motor efficiency. Authors have defined collective losses across a squirrel-cage motor. Hellwig’s statistical method has been employed to determine the characteristic estimating collective losses based on experimental testing of 21 motors with power up to 2.2 kW. Simulation and experimental results are used to check the validity and performance of the proposed method. The main advantages of the method is its simplicity of use and minimal data requirements.

In this paper we present results of DLTS investigating HIT solar cells. Analysis of DLTS spectra gave deep level activation energies and concentrations. However this method hardly allows to find spatial localization of these defect states. Therefore here we developed a method to find separated values of recombination rates corresponding to different spatial regions: a-Si layers, interfaces, depletion region and quasineutral base. We quantity found that recombination in the depletion region and at the interfaces strongly dominate and affect efficiency of the cell. Here we show that this technique is useful for interpretation of DLTS data and investigation of recombination processes in HIT solar cells.

Article presents problems related to disturbances in power networks. The issues will be presented on a global and local level. Disturbing the quality of power affects the correct operation of electric devices. The consequence of disturbances in the quality of energy and interruptions in the supply of electricity are significant financial losses. In particularly hazardous cases, human life may also be endangered. The authors present the causes that affect the deterioration of the efficiency parameters of electricity. Particular attention will be given to recipients which require high reliability of power supply. There will be presented results of research carried out at various points of the power system. The sources of interference will be indicated. The results of the electric energy quality tests for selected power generators will be introduced. Authors submitted ways to improve the quality of electricity. The article will also present the problem of ensuring continuity of electricity power supply. This issue is especially important in case of major failures in power systems (blackouts). System failures are a threat to the proper functioning of the international energy systems. In the summary, authors are going to introduce conclusions regarding the quality of energy in power grids supplying industrial and municipal (individual) customers.

The recent studies on employee’s flexibility are showing that the amount of career-ready employees with the required competences, who are also motivated, is rising. In many operational work positions in modern manufacturing companies, employees must manage a wider range of issues and responsibilities than before. Engineering education has been and will continue to be vital in everyday life of people around the real world, but students must have competences in development of creativity, activity, and cooperation to keep up with the speed of innovations. The article responds to the outputs of the National Project "Key Competences Formation and Effective Support of Students Mobility at Technology Faculties" in the context of the work and use of technology knowledge and didactics. It is also in the intention of the Faculty of Electrical Engineering and Information Technology, University of Zilina, Slovakia, through the knowledge obtained from the project research to offer each interested educational institutions an opportunity to adopt flexible education environment concept to support students’ creativity, activity, cooperation concept (CAC) in order to focus better on improving student´s learning procedure and increasing the quality of instruction procedure. The paper brings the results of the current national educational agency research project focused on effectiveness of flexible didactics with new virtual technologies, organization forms and methods in student-focused concept through the processing of experimental data of the electronics study program in the period of 2017- 2019. The implementation of a new CAC has proven an effective flexible learning environment to work well as a method for elevating key career-ready competences. The main benefit of the study is the new insight into students´ competences growth on the engineering career-ready knowledge scaffold with significant findings and recommendations. The innovative concept is based on standardized automated hardware, virtual instrumentation software and simulation-driven support with a new assessment to identify and reflect on the students´ competences learning experiences outcomes during didactic cycle to examine the flexible environment helpfulness of virtual tools and simulation driven learning and to explore how the concept enhances graduates career-ready creativity, activity, cooperation competences growth piloted with a multinational company that is a producer of automated equipment and virtual instrumentation software.

We consider the standardized Force Concept Inventory (FCI) test to be a very useful tool for determining the level of students' knowledge of Physics (Kinematics and Dynamics) and identifying the level of Newtonian mechanics understanding. The evaluation of conceptions before starting the students study at the university, that mean before beginning of semester, by using FCI pretest results can help lecturers to organize physics teaching processes better and it can help students to eliminate misconceptions. We deal with an evaluation of the freshmen’ conception in physics teaching and learning at the following technical universities in different countries: the Faculty of Electrical Engineering and Information Technology of University of Žilina in Slovakia and the Faculty of Electronics of Ryazan State Radio Engineering University named after V.F.

We present in this work polymer (IP-DIP) three-dimensional (3D) woodpile structure placed on thin glass substrate. 3D woodpile structure was prepared using laser lithography by direct laser writing process. Dimensional analysis was performed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The effect of woodpile structure on near field region was investigated by near field scanning optical microscope (NSOM). The results show, that the 3D woodpile structure generates light intensity modification due to surface patterned structure.
