Steady-State Feedback Analysis of Tele-Graffiti
نویسندگان
چکیده
We analyze the feedback loop in Tele-Graffiti, a cameraprojector based remote sketching system which we recently developed. We derive the gain through the feedback loop and the final images that will be viewed by the users of the system. We then derive the “optimal gain” as the gain that results in the final viewed images being as close as possible to the sum of the images actually drawn on the paper. We also propose a way of using the projector to compensate for insufficient ambient light and describe how our analysis is affected by: (1) automatic gain control (AGC) and (2) color imagery. We end by proposing an algorithm to decompose the final viewed images into estimates of the drawn images.

N-Policy for M/G/1 Machine Repair Model with Mixed Standby Components, Degraded Failure and Bernoulli Feedback
In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...
متن کاملA Study on State Dependent Accessible and Second Optional Service Queue with Impatient and Feedback Customers
In this paper, we study a single server Markovian queue with state dependent accessible services, reneging and feedback of customers. The server can accommodate at the most $d$ customers in the service station, after which the new arrivals have to wait in the primary queue of infinite waiting space. All arrivals demand First Essential Service (FES), after completing FES, customers decide to joi...
