Marine industry requires continued development of new technologies in order to produce oil. An essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. In this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...

The nonlinear system becomes an area with numerous investigations over the past decades. The conventional modal analysis could not be  applied on nonlinear continuous system which makes it impossible to construct the reduced order models and obtain system response based on limited number of measurement points. Nonlinear normal modes provide a useful tool for extending modal analysis to nonlinea...

Synesthesia is a phenomenon in which an experience in one domain is accompanied by an involuntary secondary experience in another, unrelated domain; in classical synesthesia, these associations are arbitrary and idiosyncratic. Cross-modal correspondences refer to universal associations between seemingly unrelated sensory features, e.g., auditory pitch and visual size. Some argue that these phen...

Recent studies have demonstrated participants' ability to learn cross-modal associations during statistical learning tasks. However, these studies are all similar in that the cross-modal associations to be learned occur simultaneously, rather than sequentially. In addition, the majority of these studies focused on learning across sensory modalities but not across perceptual categories. To test ...

The research described in this paper focuses on the application of modal strain techniques on a multi-girder bridge superstructure with the objectives of identifying the presence of damage and detecting false damage diagnosis for such structures. The case study is a one-third scale model of a slab-on-girder composite bridge superstructure, comprised of a steel-free concrete deck with FRP rebars...

OVERVIEW The efficacy of modal analysis in detecting and localizing damage is debated based on sensitivity concerns – modal frequencies are extremely insensitive to small changes in local parameters and geometry. Convincing evidence of sensitivity issues is vast, and here we cite a single field study of a 163 ft. long, 10 ft. deep experimental test girder from an I40 bridge in Bernalilo County ...

Recognizing other individuals by integrating different sensory modalities is a crucial ability of social animals, including humans. Although cross-modal individual recognition has been demonstrated in mammals, the extent of its use by birds remains unknown. Herein, we report the first evidence of cross-modal recognition of group members by a highly social bird, the large-billed crow (Corvus mac...

In the framework of functional testing from algebraic speci cations, the strategy of test selection which has been widely and e ciently applied is based on axiom unfolding. In this paper, we propose to extend this selection strategy to a modal formalism used to specify dynamic and reactive systems. Such a work is then a rst step to tackle testing of such systems more abstractly than most of the...

We explore the extent to which the principles of classical modal logic can be applied to fully quantum settings. Modal logic models our reasoning in multi-agent problems, and allows us to solve puzzles like the muddy children paradox. The Frauchiger-Renner thought experiment highlighted fundamental problems in applying classical reasoning when quantum agents are involved; we take it as a guidin...

Piezoelectric force sensors are used in more and more industries and areas for the monitoring of the production process or testing products’ performance. In some high-precision testing fields, the dynamic measurement performances of the test system itself have to be examined. Based on the dynamic response mathematical model of test system itself, this paper studies the dynamic measuring acceler...
