'Our hemodynamic research promote avoiding brain haemorrhages'

Benjamin Csippa, PhD student of the Department of Hydrodynamic Systems, works in a research group supported by the National Brain Research Program 2.0.

'What we can assume based on our current understanding, and can be valid for all types of aneurysm, is that irregular time-dependent flow patterns can come into existence, which modifies the structure of the vessel wall, initiating and eventually growing an aneurysm. In the process, this local irregular flow mechanically disproportionately stresses the endothelium. The endothelium – in effect – translates this mechanical signal into a biochemical one, which promotes a set of biological processes, to form an aneurysm.

The study of aneurysm formation mechanisms is a bit closer to what we can call basic research. Its clinical significance is, probably, that the doctors can have more in-depth knowledge with such information, about the natural course of the illness. Yet, our research findings can have practical impacts as well.'

‘An excellent environment for education and research’

The renovation of our faculty’s 150 square meter lab hall in Building G was finished in the middle of April 2020. For this occasion, we had a review of the investments of the last few years. About the lab renovation, we interviewed Márton Takács, associate professor, deputy head of the Department of Manufacturing Science and Engineering. More

Three cathegories were won by BME-GPK teams in pneumobile competition

Contest of 2019
BME's mechanical engineering students won three from four cathegories at Emerson XIII. International Aventics Pneumobile 2020 contest. In the contest, participants had to design and develop a pneumatic vehicle. 

The first prize in the 'Most innovative vehicle' and 'Best technical documentation' cathegories were gained by the team BME Műszakik AiR-115, of our faculty. The team's tutor was Dr. Zsolt Farkas, the senior lecturer of BME-GPK (Budapest University of Technology and Economics, Faculty of Mechanical Engineering), Department of Machine and Product Design.
The other team of our faculty, Löködönc Green Thunder gained prize for the best control system, with the tutorship of András Czmerk, senior lecturer of BME-GPK MOGI (Department of Mechatronics, Optics, and Mechanical Engineering Informatics). Both teams gain podiums since years, certain teams of Műszakik gained the prize for the 'best pneumobile' in 2019, 2016 and 2015. But BME-GPK student teams won the contest in 2011, 2013, and 2014, and gained podium in several categories.
Due to the emergent situation, this year, for the first time, the event was organized online, without a live round, only with the judgement of technical documentation and CAD designs. The founders of the contest, firstly organized in 2008 was, to create an engineering event, where future engineers have the opportunity to get glimpse into pneumatics. The teamworks were helped by Tibor Szabó, the master lecturer of MOGI.

'The mathematic models we use enable us to analyse various complex networks'

Tamás Huzsvár and Richárd Wéber, PhD students of BME Faculty of Mechanical Engineering, Department of Hydrodynamic Systems examine the network theory and energy emission aspects of potable water networks. Their lecture was awarded a special award and a Public Choice Award on the potable water- and sewage system technology-related Dulovics Junior Symposium. Interview. 

What do you study in your PhD researches? 

Richárd Wéber: We both would like to build up and precise mathematical models of potable water networks, and draw overall conclusions about their operation. Our aim is that potable water should be transferred in proper quantity, most efficiently and inexpensively, to the consumers. We work based on the 1D hydraulic model of potable water networks, using mathematical tools of network theory.

What challenges can reduce the efficiency of these networks?

Richárd Wéber: For instance, there are vast quantities of leakages, due to the erosion of the pipes. It is pumped into the network, but no one pays for it, it is called non-invoiced water. There are methods to estimate the locations and how to reduce this loss. It is otherwise not necessarily secure, because these elements are located 1-2 meters underground, so it is costly and uncomfortable. More
