Lab training is a key element in most engineering education programs in preparation for engineering profession tasks. Universities worldwide are exploring new possibilities and different forms to arrange online and blended labs as an alternative to pure campus training. This study compares online and blended lab setups in four cases of engineering education at European technical universities. The results show that online and blended labs can achieve similar learning outcomes, with blended labs being particularly effective in combining online learning with hands-on elements. Students reported high levels of satisfaction and teachers noted the benefits of online learning environments, but common challenges included ensuring student engagement, increased self-regulation requirements, and the high effort needed to design online or blended environments. The study provides course design guidelines and discusses implications for future research and implementation in universities worldwide.

An experimental laboratory setup is presented where students can familiarize, study, set-up, tune and test the propulsion motor drive. Paper gives a brief overview about experimental setup construction and application, as well about the course, where it is used, and laboratory exercise contend. The topics covered by developed laboratory works could be interesting for interdisciplinary studies in different fields, e.g. electrical and mechanical engineering.

Today's manufacturing operations are faced with the need to reduce cost and be more competitive with as small resources as possible. Therefore, engineers need to use high level methodologies and software to facilitate the development, maintenance, and documentation of the production lines. These must include modeling, formal validation, prototype simulation and testing before building a real machine. The aim of this paper is to describe methods to be used by small and medium size enterprises for the design of industrial automation systems and to develop a methodology and guidelines applicable to training of engineers.

This paper presents the output filter analysis and design for the high-voltage isolated DC/DC converter. The topology of the filter is the second order low-pass LC but in row with the relative simplicity it demonstrates excellent performance. Filter steady state analysis as well as simulation results are discussed.

Modern information and communication technologies have changed the concept of conducting laboratory experiments and learning the theories behind them. New terms like "distant learning", "remote laboratories", "virtual learning environments" etc have emerged. To follow the mainstream and improve practical aspects of given education, the TUT has started designing its own remotely controlled electrical drives laboratories where students can make experiments on real objects. Designing a remote laboratory presumes finding solutions to problems regarding technical, didactic, security and financial requirements as well as the integration into a wider distant learning environment. These requirements give a basis for laboratory structures and methodology.

This paper describes the analysis of price fluctuations in the Nord Pool Spot (NPS) and the possibilities to introduce consumption scheduling and energy storage equipment to reduce price fluctuations in households using the real-time open market electrical energy tariffs.
