Narrow Results

Although technology acceptance and adoption have been intensively investigated using well-established theories called the Technology Acceptance Model (TAM) and Innovation Diffusion Theory (IDT), this paper claims that Emerging Technology (ET) has particular characteristics that differentiate it from the adoption of traditional technology that has been used for a long time. Therefore, it argues that TAM and IDT are not sufficient to investigate the adoption of ET. Investigating the adoption of ET requires additional, unique, non-traditional factors (constructs). Therefore, this paper aims first to conceptually develop a model of ETs adoption (META). To achieve this objective, TAM and IDT will be reviewed. Then, this paper will use the characteristics of ET as the basis for developing the factors that influence the adoption of ET. Secondly, to validate the model, a case study of an ET (i.e. Virtual Reality) will be analysed in-depth to reveal the factors that influence on its adoption by applying META. A discussion of META applications and implications for future research are also provided.

In the analysis of a surface acoustic wave resonator for modeling and design, wave velocity considering the influence of complications of the structure is a very important parameter. Currently, solutions of surface acoustic wave velocity are mainly obtained from the simplified semi-infinite model. In this study, we analyze surface acoustic waves in a finite isotropic substrate with periodic electrodes by using the two-dimensional theory for finite elastic solids. Numerical examples, which use isotropic materials as substrates, show that surface acoustic waves will have a lower velocity with the increase of electrode thickness. When the thickness of electrode is zero, surface acoustic wave will have the same velocity with the corresponding semi-infinite substrate case.

The analyses of surface acoustic waves propagating in finite elastic solids are mainly done with the simplified semi-infinite model. In this study, we analyze the characteristics of surface acoustic waves in finite anisotropic substrates with periodic electrodes by using the two-dimensional theory for finite elastic solids. Through the solutions of surface acoustic wave velocities, we find that surface acoustic waves will have a lower velocity with the increase of periodic electrode thickness. When the thickness of periodic electrode is zero, surface acoustic wave will have the same velocity with the corresponding semi-infinite substrate case. The analytical model we use is closer to the actual surface acoustic wave resonators, and at the same time the finite sizes of structures and the effect of electrodes for their layout, size, and material properties are considered. The method and results from this study will have important practical applications in the analysis of surface acoustic wave resonator for modeling and design.
