Doc. Alexander Hošovský – Personality of Science and Technology Under 35 Years Old

Awarded doc. Ing. Alexander Hošovský, PhD., is an expert in computational intelligence, automatic control of production machinery and processes, as well as mechatronics, from the Faculty of Manufacturing Technologies with a site in Prešov, the Technical University in Košice.

The culmination of the Week of Science and Technology in Slovakia is the awarding of awards for work and achievements in the area of science and technology. The awards ceremony took place on 10 November 2016 at 7PM in the INCHEBA Expo in Bratislava. The Award for Science and Technology in five categories (Personality of Science and Technology, Lifelong Achievements in Science and Technology, Personality of Science and Technology Under 35 Years Old, Populariser of Science, and Scientific and Technical Team of the Year) were given by the Minister of Education, Science, Research and Sport of the Slovak Republic Peter Plavčan, who is the patron of the event. The Award for Science and Technology has been awarded since 2014, replacing the award of the Minister of Education, Science, Research and Sport of the Slovak Republic. The objective of this transformation is to increase the social prestige of the awards for science and technology.

Doc. Ing. Alexander Hošovský, PhD., was awarded the Award for Science and Technology in the category Personality of Science and Technology Under 35 Years Old. Proponents: Slovak Rectors' Conference and the Higher Education Council of the Slovak Republic.

Doc. Ing. Alexander Hošovský, PhD. (1981), was born in Prešov. Between 1999 – 2004, he studied at the Air Force Academy of General Milan Rastislav Štefánik in Košice, at the Department of Avionics, with focus on radio- and radio-technical equipment of airplanes. Since 2008, he works at the Department of Mathematics, Informatics and Cybernetics, Faculty of Manufacturing Technologies with a site in Prešov, Technical University in Košice. He is dedicated to research in computational intelligence, modelling and control of machines and processes, with a narrower specialisation in systems powered by non-conventional propulsions, especially by pneumatic artificial muscles.

He authored or co-authored a total of 70 scientific papers (of which five in peer-reviewed journals, two scientific monographs and ten works in prestigious journals, respectively in the SCOPUS database), 31 patents and utility models with a total of 190 citations, of which 25 from experts from various universities in the world. He is a member of the top team – Advanced Manufacturing Technologies Research Team of the Technical University in Košice and a member of the program committee of the reputable conference IJCCI – IJCNN section. He was also a reviewer of articles in renowned peer-reviewed journals: International Journal of Mechanical Sciences, Control Engineering Practice, Advances in Mechanical Engineering, Information Technology and Control, Acta Polytechnica Hungarica, Strojniški Vestnik and Complex & Intelligent Systems.

We interviewed Doc. Ing. Alexander Hošovský, PhD.

M. BARTOŠOVIČOVÁ: You were awarded the Award for Science and Technology. What does this award mean to you?

A. HOŠOVSKÝ: "This award brought forth a variety of diverse feelings, which have been appearing gradually. The first was a surprise, because in my work, in which I try to do my best, I do not realise that it could be appraised in this way. This feeling, however, was replaced by joy when I began realising the value of such award as well as the fact that some results of my work can gain the awareness of a broader range of scientific communities. The third feeling is also a certain degree of responsibility that such award brings, as fulfilling of a scientific mission should not be a time-limited activity."

M. B.: You have received this award for research of computational intelligence methods in the area of modelling and management of systems based on non-conventional propulsions with artificial muscles. Could you at least briefly explain your research?

A. HOŠOVSKÝ: "The research concerns the pneumatic artificial muscles (PAMs) and the mechanisms, which utilise them for propulsion. These are propulsions, which consist of rubber tube and the braiding from a certain type of filaments. They shorten when filling with compressed air and this movement can pull a load. They have a very high ratio of strength/weight because they are light and can develop a considerable force. However, it is difficult to describe them mathematically. For the best results, it is therefore necessary to use methods that are usually inspired by nature, respectively by the intelligence of people and enable the finding of often suboptimal, but still good solutions even for complex problems, where the mathematical description is not available or is imprecise. However, obtaining good results, such as a robot arm driven by PAMs, is not easy since there are a number of conditions that need to be considered and also a lot of parameters, more or less significantly influencing the results that need to be set."

M. B.: How long have you been working on this research and when will its results be applicable in practice?

A. HOŠOVSKÝ: "I have been dealing with this research since the start of my doctoral studies, i.e. since 2005. For its application, it is first of all important to carefully consider the application of the resulting mechanism utilising PAMs, because their specific characteristics essentially preclude achieving the accuracy required in precision manufacturing processes implemented by the contemporary industrial robots. Pneumatical artificial muscle as a propulsion could be seen rather as an element suitable for the realisation of machines for specific applications, particularly with regards to expanding the representation of robots and manipulators safe for human contact. Therefore, it is necessary to reckon with the fact that the use of complex mechatronic systems based on PAMs is subject to the overall change in the current concept of the production process, which may take years. On the other hand, simpler applications are also possible, where the precision requirements are not as strict and the PAMs could be used as a cheaper alternative to the currently used propulsions – e.g. using one single muscle for the propulsion of simple devices. Practical use of such solutions would only require the adaptation of the (existing) mechanism for integrating muscle and in that case, we are talking about significantly shorter time frame."

M. B.: What are you dealing with nowadays?

A. HOŠOVSKÝ: "At the level of PAMs research, I work on developing an experimental model of manipulator arm, as well as on the control with two stages of freedom propelled by PAMs. Later, there could be an extension for further stage, which would allow the rotation of the arm in space. PAMs research area is not the only one that I deal with, even though it is a crucial area in terms of applicability. My wider area is the computational intelligence, which is suitable for many systems and processes. Moreover, the area of optimisation, which is a subset of mathematics, is connected to the utilisation of these methods. Specific area, which is required for the control of machinery or processes, is the identification of dynamical systems. To obtain good results, it is necessary to connect all of these areas. So nowadays, in addition to PAMs, I also deal with the application of knowledge research from all mentioned areas for modelling and management of industrial systems, i.e. processes."

M. B.: What research would you like to do next?

A. HOŠOVSKÝ: "I want, of course, to continue the research of PAMs in the area of robotics and the application of various methods of computational intelligence. I would also like to use the past experiences and knowledge for other types of non-conventional propulsions, such as shape-memory alloys (SMA) as well as artificial muscles based on composites consisting of ionic polymers and metal. While the first of them have a long history and interesting results, including real applications, the others are really rather a laboratory 'exotics' with remarkable properties. Similar to PAMs, there is also a need to face enormous challenges in modelling and management of these propulsions, but this is exactly what I like about this work."

M. B. Thank you for the interview. On behalf of the editorial staff, I congratulate you for the award and wish you many more success.
