This paper presents four case studies that explore the adoption and acceptance of mobile technologies and services within the context of the privacy-value-control (PVC) trichotomy. The technologies studied include: the mobile phone, electronic toll payment tags, e-passports, and loyalty card programs. The study shows that despite the potential barriers to adoption in each of the depicted cases, the applications were embraced with great success soon after their introduction. An understanding of why these mobile innovations succeeded in spite of the concerns surrounding them will serve to help practitioners understand other issues currently plaguing emerging technologies like radio-frequency identification (RFID) tags …

This paper presents a novel Adaptive Tuned Vibration Absorber (ATVA) using the enhanced magnetorheological elastomers (MREs) for powertrain vibration reduction. The MRE material used in this application includes micro-sized iron particles enhanced by adding nano-sized magnetic powders. With the enhancement, MRE's elastic modulus significantly increases due to the MR effect. In the new ATVA, the MRE plays a role as a torsional spring whose stiffness coefficient can be varied with an external magnetic field. Additionally, this ATVA could operate in shear-squeeze mode rather than shear mode. Thus, the frequency range is much wider than that of general MREs. Such property …
