Scheduling algorithms are proposed for a computational process in single-processor real-time systems. Time it takes to execute the tasks is assumed to be known imprecisely and is given by a time interval, which leads to imprecise task timing (jitter).
We explored the perception of image focus in patients with cataracts, and how this perception changed following cataract removal and implantation of an intraocular lens. Thirty-three patients with immature senile cataract and with normal retinal function were tested before surgery and 2 days after surgery, with 18 of the patients retested again at 2 months… (More)
