Self-developed Controller System –based on Open-Source Applications
97-105Views:207In the University of Debrecen Building Mechatronics Research Centre faced by the application of building automation technology, are tackled by cutting edge research performed at the Research Centre. The embedded device system, the focus of the ongoing project at the Research Centre, is programmable, reconfigurable, and adjustable. The design of an efficient embedded system must meet regulatory requirements, for optimizing building energy efficiency. The system provides solutions for a range of industrial applications, and peaks the interest of building services providers (e.g. SMEs).

The Use of Additive Manufacturing for Wind Tunnel Simulations
62-71Views:290The current economical situation requires aircraft operators to start organizing their activity in the direction of carbon neutrality using innovative solutions.
The goal of present study is to desing a brand new wingtip device using 3D printing which helps reducing aerodynamical drag, leading to fuel efficiency and less carbon emission with its innovative shape.

Management Practices from Christian Point of View
14-30Views:365Globalisation is a complex and worldwide process overarching historical times and continents. However the phenomenon brought efficiency and new opportunities to companies, providing practically free access to raw materials, labour and knowledge, it also caused negative effects like the degradation of the biosphere, greater social and economic inequality especially in the developing countries. There are some companies operating worldwide which have acquired great economic power and influence. and governments have only limited possibilities (if any) to regulate their operation. The expenses of profit maximisation are high, which are often ‘paid’ by the socialnatural environment (as externalities) and/or by humans. The aim of our study is to overview how current business relations could be formed to be more „human friendly”. The research is done from a Christian philosophy point of view, focusing on the employees as the major stakeholder group of the comanies. As part of the study some practical examples and Hungarian organisations related to this topic are introduced in order to highlight the relevance of the topic.

Laboratory-scale gasification of brown coal and char from RDF pyrolysis
188-193Views:253The pyrolysis is a promising process for producing syngas from wastes. However, the by-product of the technology may contain large quantities of carbon, therefore it is suitable for further syngas production. In this paper we examined the steam gasification of brown coal from Felsőnyárád and char from RDF pyrolysis derived from an experimental pilot plant operating in Zalaegerszeg. We performed our experiments in a laboratory-scale fix-bed reactor at 900 °C. The aim of this work to examine the efficiency of syngas production from pyrolysis char, as well as to explore the similarities and differences of the thermal decomposition of the feedstock materials.

Menedzsment módszerek az Ipar 4.0 tükrében
507-514Views:888The fourth industrial revolution poses major challenges for organisations in terms of technological aspects and from a management point of view, too. Good (effective) management is vital as it can help overcome the difficulties arising from shortages of skilled labour and from cost-cutting pressures, and it can help improve efficiency of resources. Innovations require management methods that support the introduction of industry 4.0. In my review of the literature, I aim to find out how the current level of sophistication in this new field can help managers of SME to better embrace change. Based on the reviewed literature, from management point of view, organisational structure, leadership style and HR practices are key to creating an atmosphere conducive to learning and innovation. In terms of structure, researchers do not suggest one thing to apply, but emphasise that industry 4.0 is characterised by an unstable, changing environment, so it is worth developing a structure that is characterised by decentralisation, few rules, horizontal communication and collaborative teamwork, i.e. much more organic than mechanical. In terms of different leadership styles, it is the transformational leadership that is the most often mentioned, however, in case of industry 4.0, we need even more because it can have various limitations. Even before industry 4.0, literature has highlighted that the recommended leadership style can be defined as the combination of transformational and transactional leadership; research in industry 4.0 in recent years also emphasises that it is the expanded construction of a knowledge-driven leadership style that blends the two, which can best facilitate innovation and learning. Managers can develop employee skills and improve their learning abilities through a variety of HR practices. So the right structure, leadership style and HR prepare the organisation for industry 4.0 by facilitating learning, improving skills and innovation.
