In  this  paper  a  new  method  is  presented  for  structural  damage  identification.  First,  the damaged structure is  excited by short  duration impact acceleration  and then, the  recorded structural displacement time history responses under free vibration conditions are analyzed by Continuous Wavelet Transform (CWT) and Wavelet Residual Force (WRF) is calculated. Finally, an effective d...

This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...

In this paper, we present a combined structural and inter-frame skipping method for quality aware processing of MPEG-2 video upon overload situations. The method selects video frames both based on the structural properties, such as frame types, sizes and position in the video stream, as well as on the internal, sub-frame characteristics, i.e., the number of relevant macroblocks within a frame.
