The bender element test has shown to be a reliable tool to determine the shear wave velocity. This paper aims to extend the bender element technique to also measure the material damping ratio in a triaxial cell. Three different interpretation techniques are developed for this purpose. The first technique uses a modal test of a cylindrical soil spec...
The use of AFM is simplified, its application field is extended, and its acceptance is increased by substituting the optical detection of cantilever deflections by integrated electrical sensors. Accordingly, four piezoresistors are fabricated on the existing Si cantilevers with sharp tips. The resistors with positive and negative piezoresistivity c...

Measurements of pressure variations in the source region are to be conducted in conjunction with an investigation of sound generation mechanisms on axial flow turbomachinery. The capacitor microphones normally used in acoustic measuring techniques cannot be used universally because of their volume. In addition, there are plans to measure pressure v...
