The problem of random vibration response based damage detection for a composite beam under non-measurable environmental and operational variability, presently temperature and tightening torque, is considered via a Functional Model based method. The method is based on proper representation of the healthy structural dynamics under any environmental/operating conditions via a data based Functional Model obtained in the method’s baseline phase and used to define a ‘healthy subspace’. Damage detection is, in the method’s inspection phase, achieved by examining whether or not the current dynamics belongs to the healthy subspace. The experimental results obtained for damage detection on a composite beam indicate excellent detection performance, with correct detection rate of 100% for false alarm rate as small as 1%. The superiority of the proposed method is confirmed via comparisons with a state-of-the-art Principal Component Analysis based method.

The article considers a structural-functional model of school readiness development of senior preschool children based on the use of kinesiological exercises, which allows to ensure an increase in the level of the children’s school readiness. The model has been implemented in a particular preschool educational institution. The presented material makes it possible to conclude that the designed and tested model reveals the role of kinesiological exercises in the formation of senior preschool children’s school readiness and its efficiency.
