Abstract: This work deals with the design and experimental evaluation of a passive/active cantilever beam autoparametric vibration absorber mounted on a twostory buildinglike structure (primary system), with two rigid floors connected ...

Abstract: To achieve the long-term challenge of nuclear energy public acceptance in Thailand, nuclear safety research needed to be properly determined in both domestic and international directions, especially in the 2020s which was ...

Abstract: A technique to synthesize optimal excitations for dynamic testing is presented. A quadratic function of the frequency response at modeled degrees of freedom of the test object is employed as ...

Abstract: In this paper the classical time domain design problem of position servoactuators having proportional plus derivative (PPD) error controllers is reconsidered. Control system stability is represented ...

Abstract: We reexamine the coupled lower boundary condition of Chen and Trenberth and show that for consistency the vertical velocity should be corrected from the mountain surface to the lowest computational level. This correction ...

Abstract: The use of dense gases in many technological fields requires modern fluid dynamic solvers capable of treating the thermodynamic regions where the ideal gas approximation does not apply. Moreover, ...

Abstract: Several shortcomings of available standards, regulatory guides, and review plans for seismic qualification testing are identified. A rational test nomenclature is proposed. A standard test is ...
