Study on the optimal design of mistuned bladed disk (Simultaneous optimization of forced and self-excited vibration and amount of unbalance)

Although bladed disks are nominally designed Urban to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, deviations in the material properties, and wear during operation.These small variations break the cyclic symmetry and split the eigenvalue pair

Rainfall and runoff regime trends in mountain catchments (Case study area: the upper Hron River basin, Slovakia)

This paper presents an analysis of trends and causes of changes of selected hydroclimatic variables influencing the runoff regime in the upper Hron River basin (Slovakia).Different methods for identifying trends in data series are evaluated and include: simple mass curve analysis, linear regression, frequency analysis of flood events, use of the In
