METHODS Twenty-seven subjects wore hydrogel lenses (Focus Dailies; Alcon) bilaterally for 10 hours on two separate days. Comfort was reported using 1-100 numerical rating scales (1 = intolerable(More)
The emergence of cloud technology has raised a renewed emphasis on the issue of scalable on-demand computing. Cloud back-end support of small devices such as sensors and mobile phones is one important application. We report our preliminary study of measured characteristics of distributed cloud computing infrastructure for collaboration sensor-centric(More)
While the emerging cloud computing systems promise infrastructure resources to support application scalability, there are publications of systematic evaluation of this emerging information technology infrastructure in general, and no obvious publications for some representative collaboration applications in particular. We describe a methodology to study the(More)
