This study of an externally forced, amplifier-type turbulent reacting swirling annular jet presents a low-order model for the flow response to transverse acoustic excitation and compares model's predictions with experimental measurements. The is formulated based on linear stability calculations about mean eddy viscosity fields obtained from separate measurements unforced flow. yield weakly glob...

In the present cross-linguistic study two experiments were conducted to investigate the effects of age and linguistic background on response tendencies of preschoolers toward forced-choice questions. A total of 163 2to 5-year-old children, including 63 Persian speakers, 57 Kurdish speakers and 43 English speakers, were asked a set of forced-choice, two option questions about familiar and unfami...

To experimentally identify the dynamic characteristics of a structure, also referred to as system identification, two methods are available: Forced Vibration Testing (FVT) and Ambient Vibration Testing (AVT). The basic ideas of these methods are shortly presented. The main part of the paper deals with practical problems which are to be overcome when performing such a system identification test....
