The influence of infills on the seismic response frame structures has been long recognised. On one hand, presence may be beneficial, due to their contribution dissipate energy. other irregular infill distributions in plan or elevation can lead concentration displacement demand localised parts building. It is noted that lack more panels depend original building layout generated by collapse durin...

objective: antisocial, aggressive and delinquent behaviors in adults often begin early in life. basal cortisol is a valuable biological marker in children with disruptive behavior disorder (dbd). to investigate the association between biological factor (cortisol) and disruptive behaviors, we studied the effect of family training on salivary cortisol level in children with dbd. methods: basal sa...

This investigation is concerned with application of nonlinear fluid viscous dampers for asymmetric-plan systems. For this purpose, the behavior of nonlinear fluid viscous dampers is summarized first followed by the effects of damper nonlinearity on seismic response of asymmetric systems. It is shown that the peak force in nonlinear damper tends to be smaller compared to linear damper. However, ...

In this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. Seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. The finite element modeling technique (SAP2000 Software) is used for analysis. Time History analyzing was done to achieve this purpose. For nonlinear dynamic analysis, the responses of ...

In seismic reflection prospecting for oil and gas a key step is the ability to estimate the seismic wavelet (impulse response) traveling through the earth. Such estimation enables filters to be designed to deblur the recorded seismic time series and allows the integration of “downhole” and surface seismic data for seismic interpretation purposes. An appropriate model for the seismic time series...
