This paper suggests the adaptive quasi static Ritz vector (AQSRV)-based model reduction scheme of applying an error indicator for efficient numerical simulation of the acoustic metamaterial systems with the characteristics of broadband, inhomogeneous, and anisotropic. In contrast to a conventional mode displacement method (MDM)-based model reduction scheme, the proposed method has characteristi...

Direct displacement based design (DDBD) is a conceptual framework that directly design a structure to achieve an expected performance level under specified seismic intensity. In this study, two important issues relevant to torsional response of mass eccentric 8-story RC building designed with DDBD approach are investigated. These issues are including the effects of unbalanced mass distribution ...

Abstract. Recently, there has been an increasing emphasis in the Indirect bridge health monitoring method employing passing vehicles, which is regarded as one of most effective approaches damage screening. However, few researches have conducted on Drive-by inspection using vehicle displacement profile indicator due to challenges measurement and result accuracy. This paper proposes optimization ...

The present study assessed condylar displacement between initial maximal habitual intercuspation (MHI) and centric relation (CR), recorded after using a deprogramming occlusal splint for an average period of 7.8 +/- 2.1 months prior to any orthodontic treatment. The sample consisted of 22 subjects, 11 male and 11 female, with an average age of 14.2 +/- 1.4 years, with Class II malocclusion and ...

Discontinuity layout optimization (DLO) is a relatively new upper bound limit analysis method. Compared to classic topology methods, aimed at obtaining the optimum design of structure by considering its self-weight, building cost, or bearing capacity, DLO optimizes failure pattern under specific loading conditions and constraints minimizing dissipation energy. In this work, we present modified ...
