Industry 4.0 is mainly represented by the digitalization technologies of physical industrial assets, thus obtaining the cyber-physical systems. A key role in digitalization developing is indeed played by possibility to develop a realistic virtual model (3D model) and using this model in virtual simulations to test the functionality of the system at possible scenarios from real world. The paper presents the modelling a mechatronic system represented by a three-dimensional cylindrical type manipulator in Automation Studio software and aims creating cinematic animation which will be used in the field of virtual commissioning. This approach in Industry 4.0 paradigm is studied in the academic environment and in the industrial research from last decade time, because generate major benefits such as in remote accessibility for learning, time efficiency from planning to real setup with possibility of detection and debugging of errors in the system, for minimizing time commissioning and predictive maintenance.
The low radiation conditions and the predominantly phase-object image formation of cryo-electron microscopy (cryo-EM) result in extremely high noise levels and low contrast in the recorded micrographs. The process of ...

A concept of the porous core electromagnet is studied. The form for the electromagnet core was printed using 3D technique. The core was manufactured manually using iron filings and cured in room temperature and air pressure. The aim of this paper is to deliver initial analysis of the proposed powder core together with the modelling procedure by the using finite element method, and to compare the experimental results of the manually manufactured electromagnet. The material property of the numerical model was adjusted to fit the experimental results. Finally, the electromagnet was tested in the levitation real–time experiment.

In this article a multimedia computer-assisted learning (MCAL) system is presented. The major objective of this work was to investigate the potential of using such systems as tools for transferring instructional course information through various types of computer media as opposed to the classic CAL systems. The philosophy and techniques employed to design the system are investigated. Usage of the implemented system and its merits have been illustrated through its application to teach engineering students and technicians the theory and concepts of marine radar. System design, implementation, test, and revision phases are presented and discussed.

There is need to replace the traditional materials used in mechanical constructions with cheaper materials characterized by high durability and simplicity of manufacturing. An alternative technology is 3D printing technology that uses ABS material (poly (acrylonitrile-co-butadiene-co-styrene)). 3D printing technology ensures the rapid change of model dimensions and shapes at the prototyping stage and a relatively cheap cost of new elements. There are many plastic materials producers on the market for a 3D printer. In this paper two of them have been choosen to a comparison and their mechanical parameters have been determined. The modal analysis of this material was carried out and the obtained values of resonance frequencies were compared.

The paper presents a novel method of fault location and the calculation of transverse impedance of a fault in a damaged medium voltage cable. The method is based on the measurement of input impedance at one end of the cable with an open and short circuit state at its other end with appropriately selected frequency. The obtained results were compared with those obtained by means of the reflectometer. The effectiveness of the method was verified numerically and experimentally.

The paper presents stages of creating a measurement system for a light-weight electric vehicle of the Silesian Greenpower team. The aim of the work was to design a measuring device and mobile application for drivers and the team. The system itself consists of a measuring device, applications for Android and Windows. The purpose of the device was to provide information about the car in real time. The collected data is saved and displayed on the driver's phone. At the same time, the data is stored in a database, which allows the whole team to observe current parameters. Working of the measurement system has been described in the paper. Screenshots from individual applications, a specification of selected sensors and source code of the created applications have been presented. The summary of the project are graphs showing the smooth operation of the measurement system during races taking place on the Rockingham circuit in the UK.
