Zrání sýrů sledované pomocí akustických metod
Severa, L. ; Nedomová, Š. ; Trnka, Jan ; Dvořáková, Pavla ; Buchar, J.
The objective of this study consists in the assessement the suitability of using the acoustic impulse-response technique to evaluate Edam cheese texture and maturity. The acoustic response - history of the surface displacement and the surface velocities were detected by the double-channel laser-vibrometer. The history of the impact force has been also recorded. The non-destructive impact tests could be useful for predicting cheese ripening.

Optical computation in Matlab
Dvořáková, Pavla
The contribution deals with the optical computation in Matlab. Matrix methods in paraxial optics is a powerful tool which allow to track any ray during its propagation through an optical system by succesive matrix multiplications. The matrix operation can be then easily and clearly programmed in Matlab.
