this paper uses a psopc model based non-destructive damage identification procedure using frequency and modal data. the objective function formulation for the minimization problem is based on the frequency changes. the method is demonstrated by using a cantilever beam, four-bay plane truss and two-bay two-story plane frame with different scenarios. in this study, the modal data are provided nume...

This study investigates the sensitivity of design variables such as ultimate strength of concrete, yield stress of reinforcing steel and damping ratio to the seismic response of staggered wall structures. Two different methods for sensitivity analysis, the tornado diagram method and the first-order second-moment method, are applied to two types of model structures. Non-linear dynamic analyses a...

This study investigates how French listeners exploit phonological and phonetic cues in segmenting continuous speech into words. We examined how these listeners integrate multiple sources of information not only in lexical identification, using the cross-modal priming paradigm, but also in the storage of new lexical representations, using an artificial language learning task. Results showed that...

Speaker variability is known to have an adverse impact on speech systems that process linguistic content, such as speech and language recognition. However, speech production changes in individuals due to stress and emotions have similarly detrimental effect also on the task of speaker recognition as they introduce mismatch with the speaker models typically trained on modal speech. The focus of ...

We prove new Lindström theorems for the basic modal propositional language, and for the guarded fragment of first-order logic. We find difficulties with such results for modal languages without a finite-depth property, high-lighting the difference between abstract model theory for fragments and for extensions of first-order logic. 1 What is modal logic? I would broadly endorse the 'minimal desi...

Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel. 3-D model of the Lower Wishbone Arm is prepared by using CAD software for modal and stress analysis. The forces and moments are used as the boundary conditions for finite element model of the wishbone arm. By using these boundary conditions static analysis is carried out. Then m...

A hybrid modal expansion that combines the free field Green's function and a modal expansion will be presented in this paper based on a review and an extension of the existing modal analysis theories for the sound field in enclosures. The enclosed sound field will be separated into the direct field and reverberant field, which have been treated together in the traditional modal analysis. Studie...

We present a proposal on how to develop nonmonotonic reasoning based on the modal logic S4. As a consequence of our results we show how to present the well known semantics of answer sets, under a restricted fragment of modal formulas, using this approach. Moreover, by considering the full set of modal formulas we obtain an interesting generalization of answer sets with modal connectives. We sho...
