Brand origin: conceptualization and review

Abstract: Argues that, although researchers have studied several aspects of brands which may affect consumer purchasing processes, one significant characteristic of many brands ‐ the origin cues that they contain ‐ has received little or no attention. Reviews current research in the country‐of‐origin area related to branding, as well as the work done by other researchers on brand personality and brand image. Distinguishes brand origin from country of origin, and shows how this concept could be valuable in resolving a methodological problem with some country‐of‐origin studies. Surveys ways in which brand origin is used in practice, both implicitly and explicitly, and discusses the relationship between brand origin and the concept of the global brand. Finally, highlights potential problems associated with the use of brand origin, draws managerial implications relating to its use, and suggests areas where research is needed.

Generalized space shift keying modulation for MIMO channels

Abstract: A fundamental component of spatial modulation (SM), termed generalized space shift keying (GSSK), is presented. GSSK modulation inherently exploits fading in wireless communication to provide better performance over conventional amplitude/phase modulation (APM) techniques. In GSSK, only the antenna indices, and not the symbols themselves (as in the case of SM and APM), relay information. We exploit GSSKpsilas degrees of freedom to achieve better performance, which is done by formulating its constellation in an optimal manner. To support our results, we also derive upper bounds on GSSKpsilas bit error probability, where the source of GSSKpsilas strength is made clear. Analytical and simulation results show performance gains (1.5-3 dB) over popular multiple antenna APM systems (including Bell Laboratories layered space time (BLAST) and maximum ratio combining (MRC) schemes), making GSSK an excellent candidate for future wireless applications.

Industrial Electronics for Electric Transportation: Current State-of-the-Art and Future Challenges

Abstract: This paper presents the current research trends and future issues for industrial electronics related to transportation electrification. Specific emphasis is placed on electric and plug-in hybrid electric vehicles (EVs/PHEVs) and their critical drivetrain components. The paper deals with industry related EV energy storage system issues, EV charging issues, as well as power electronics and traction motor drives issues. The importance of battery cell voltage equalization for series-connected lithium-ion (Li-ion) batteries for extended life time is presented. Furthermore, a comprehensive overview of EV/PHEV battery charger classification, standards, and requirements is presented. Several conventional EV/PHEV front-end ac/dc charger converter topologies as well as isolated DC/DC topologies are reviewed. Finally, this paper reviews various EV propulsion system architectures and efficient bidirectional DC/DC converter topologies. Novel DC/AC inverter modulation techniques for EVs are also presented. The architectures are based on the battery voltage, capacity, and driving range.
