many previous studies used leader - member exchange to explain the quality relationship between employees and supervisors. however, in previous studies, the mechanism of this theory in creativity is not so clear. thus, this study defines the role of leaders in creating a culture of organizational learning using normative approach to examine the relationship between communication quality leader ...

A scheme for active control of nonlinear vibration of space-structures, wherein each member is modeled as a beam-column, is presented. The expressions for shear stresses transmitted to the structural member by the distributed segmented piezo-electric actuators, which are bonded on the surfaces of the member, are derived in the general case in which the structural member is subjected to moments,...

A method is presented for selecting the subset of identified structural vibration modes to be used in finite element model correlation for structural damage detection. The method is based on a ranking of the modes using measured modal strain energy, and is a function of only the measured modal parameters. It is shown that a mode selection strategy based on maximum modal strain energy produces m...

Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...
