By the past two decades IPMCs have been intensively studied because of their special capabilities for actuation and sensing.This paper presents a theoretical physics based model for analyzing the behavior of IPMC sensors in fluid environments. The mechanical vibration of the IPMC strip is described by the classical Euler–Bernoulli beam theory. The model also takes in to account the physical pro...

The drone-based multi-modal inspection of industrial structures is a relatively new field research gaining interest among companies. Multi-modal can significantly enhance data analysis and provide more accurate assessment the components’ operability structural integrity, which assist in avoiding misinterpretation providing comprehensive evaluation, one NDT4.0 objectives. This paper investigates...

The general applicability of the modal approach for model reduction is restricted by the lack of guaranteed bounds for approximation errors and the lack of a satisfactory modal dominance analysis procedure. Functional and computational enhancements of this approach are proposed. Functional enhancements arise by combining the modal techniques with other methods and by using improved dominance an...

In order to identify more accurate finite element (FE) model parameters for an as-built structure, experimental data collected from the actual structure can be used to update the parameter values. In practice, experimental data is inevitably contaminated with measurement noise, which may lead to inaccurate FE model updating. This research compares the performance of two model updating approache...

We propose a rigorous full-wave modal analysis based on the eigenmodes approach (\textquotedblleft supermodes\textquotedblright), that allows calculation of transverse electric ($TE$) and magnetic ($TM$) stationary propagation in coupled $\mathcal{PT}$-symmetric slab waveguide. Our findings show group velocity, for fundamental $TE_{0}$ supermode, passes from superluminal to subluminal speed ove...

Though Blind Source Separation (BSS) techniques have typically been applied within Operational Modal Analysis (OMA) framework, there joint diagonalization property can also be utilized within traditional input-output Experimental Modal Analysis (EMA) for the purpose of modal parameter estimation. This paper explores this possibility and suggests an approach to achieve the same. The paper presen...

This chapter will survey the temporal extensions of Description Logics. These formalisms give an emphasis to reasoning tasks such as satis ability, subsumption, classi cation, and instance recognition. The analysis will include the whole spectrum of approaches used within the Temporal Description Logics area: from the loosely coupled approaches { which comprise, for example, the enhancement of ...
