This paper studies user–level (or perceptual) QoS for multimedia applications over the Internet and demonstrates that media can compensate for each other from a perceptual point of view. For this study, we formulate the problem of the mutually compensatory property in terms of QoS mapping relation between application–level and user–level; we then conduct a simple experiment on lip synchronizati...

Unregulated utilization of renewable generation including residential photovoltaic (PV) systems can have a significant impact on load characteristics in distribution networks. For improving PV generation capabilities, power quality aspects have to be coordinated with present load characteristics. This paper discusses the harmonic content of PV generation and the influence to power quality indic...
