Thesis topic
Supervisor: prof. Alexander I. Fedortchenko, DrSc.
Thesis type: Master
Valid until: 31.12.2012

The aim of thesis is to carry out the experimental and theoretical investigations of the forced vibration of the fiber partially submerged fiber in fluid and on the obtained results to suggest the way for the viscosity extraction from the resonance frequency spectrum or curve.
