DESCRIPTION:On Friday 3rd May\, we will welcome visitors from Prof Grega
 ’s group from the Technical University in Kosice\, Slovakia. They will s
 howcase the research done in the group and their department. They will be 
 keen to hear about the research topics pursued within the Division and to 
 discuss potential collaboration (e.g. within the scope of EU Horizon Proje
 cts). Please join if you are interested.\n\nThe main theme of Professor Gr
 ega’s research is vibration mitigation in mechanical systems including d
 rivetrains with combustion engines\, generators\, propellers\, etc. The gr
 oup holds patents for tunable pneumatic flexible couplings which can be ac
 tively adjusted on the run to match operating conditions\, for instance\, 
 to achieve effectively-zero stiffness. This provides an improvement over t
 raditional passive elements such as couplings and dual-mass flywheels whic
 h are only effective over a narrow frequency band. In addition to common e
 xperimental techniques (acceleration\, noise\, thermal measurements)\, the
  group is developing novel techniques such as spectral analysis of signals
  via measurements of electromagnetic fields.\n\nIn his capacity as the hea
 d of department\, Professor Grega oversees a wide range of projects and ac
 tivities. The department was instrumental in dismantling and decontaminati
 ng a decommissioned nuclear reactor. They pioneered the development of low
 -pressure hydrogen storage in metal hydride alloy tanks and showcased the 
 system in prototypes of hydrogen-powered sports car and bus. The Prototypi
 ng and Innovation Centre is certified for additive manufacturing of aerosp
 ace components and medical implants (human and animal). Other notable area
 s of research include the use digital twins in logistics and virtual reali
 ty in design and manufacturing.
