An efficient method for the determination of the eigenvalues and eigenvectors of lightly damped systems is developed by means of a perturbation technique. The second order matrix differential equation containing mass, stiffness and damping matrices is normally transformed into a first-order state eq
We have improved the optical interferometric imaging technique that was recently used to measure local organic material concentrations in quasicylindrical cells. This allowed similar measurements for cells of arbitrary shape. The setup was used to measure the thickness of skin comeocytes. o 1% wiley
The operator notation previously developed to analyze vibrations of continuous systems has been further generalized to model a system with an arbitrary number of coupled di!erential equations. Linear parts of the equations are expressed with an arbitrary linear di!erential and/or integral operators,
