Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...

The emission enhancement of sound without electronic components has wide applications in a variety of remote systems, especially when highly miniaturized (smaller than wavelength) structures can be used. The recent advent of acoustic metamaterials has made it possible to realize this. In this study, we propose, design, and demonstrate a new class of acoustic cavity using a double-walled metamat...

People define themselves in terms of their relationship partners and they incorporate their partners into their selfconcepts. Consequently, partner enhancement—viewing one’s partner in excessively positive terms—might constitute an indirect form of self-enhancement when feelings of self-worth are threatened. To test this hypothesis, the authors gave participants evaluative feedback (e.g., succe...

Flexibility and portability are important concerns for productive empirical performance evaluation. We claim that these features are best supported by robust instrumen-tation and measurement strategies, and their integration. Using the TAU performance system as an exemplar performance toolkit, a case study in performance evaluation is considered. Our goal is both to highlight flexibility and po...

Further enhancement of the logistics targets achievement can be attained through development and use of so far locked flexibility potentials. Product structures with many variants allow for additional flexibility potentials due to the fact, that one component can become a part in one of many different final products variants for different customers. The challenge of this approach is to enable p...

Mass Customisation, meant as an approach to product definition and conception that aims at a direct involvement of the consumer in all phases of its life cycle, implies making use of appropriate tools and technologies, especially in all crucial phases of manufacturing. In particular, the manufacturing systems adopted should exhibit the maximum level of integration and flexibility to cope with t...

It is becoming increasingly apparent that the vast blue expanse of ocean—the last frontier—is not as inexhaustible as it once seemed. While we have yet to fully explore the reaches of the sea, technology has granted humans the ability to harvest its wealth. We can now fi sh anywhere, at any depth, for any species. Like the American frontier range’s bison and wolf populations brought to the brin...

Economic integration between North and South Korea occurs through three modalities: traditional arm’s-length trade and investment, processing on commission (POC) trade, and operations within the Kaesong Industrial Complex (KIC). In order, these three modalities are characterized by decreasing exposure of South Korean fi rms to North Korean policy and infrastructure. Th rough a survey of 200 Sou...

Different subregions of nucleus accumbens (NAc) have been implicated in reward seeking, promoting flexible approach responses, suppressing nonrewarded actions, and facilitating shifts between different discrimination strategies. Interestingly, the NAc does not appear to mediate shifting between stimulus-reward associations (i.e., reversal learning) when reinforcement is predictable. How these n...

Today there is an emerging tendency – from aesthetical and economical concerns – to create/refurbish venues for a wide variety of performance types, each demanding a specific acoustic. For these multi-purpose halls, electro-acoustic enhancement systems represent the most promising approach, allowing high quality results with the greatest flexibility. This paper reviews the principles of the mai...
