In order to deepen students' practical knowledge and understanding of the “Computer Networks” subject, a Monitoring Network System was developed that is able to read, collect and distribute data describing real technological processes. The Monitoring System design is based on Client/Server architecture. The model is represented by the real chemical reactor, which was created for the study of the enzymatic hydrolysis of potentially hazardous chrome-tanned wastes generated during leather manufacturing. Final system should be implemented at the university to the graduates and the system should be modular with possible communication support. The setup of the monitoring system comes with all needed explanation and procedures. © 2018, World Scientific and Engineering Academy and Society. All rights reserved.

This paper describes a proposal on a construction of a power supply module that is intended to be implemented in a small airship. Because the bearing capacity of the airship is limited, simple and efficient voltage converters must be employed. The paper provides a description of a proposal on mutual timing of these converters that leads to eliminating of the interferences caused by the currents that are drawn by the converters. The hereby described method allows the designers to use smaller capacitors and inductors which will result in smaller weight and dimensions of the power supply unit. Furthermore, an example of a voltage converter design is provided in the framework of the paper.
