Abstract

Process scheduling means allocating a certain amount of CPU time to each of the user Processes. This paper proposes a CPU Scheduling algorithm, which is meant for optimizing CPU scheduling for real time applications. It is a new approach, which uses the concept of Mean Difference Round Robin (MDRR) with dynamic time quantum, whose value changes for each cycle. It acts better than RR and Mean Difference Round Robin (MDRR) Algorithm in terms of reducing the number of context switches, average waiting time and average turnaround time. The experimental results of the proposed algorithm have been compared with Mean- Difference Round Robin (MDRR) Algorithm is found to have produced optimum scheduling.

Keywords

Abstract

Background: Facial defects can be acquired or congenital, but irrespective of etiology, any maxillofacial structure if damaged or missing will result in an unaesthetic and unappealing personality of individual. Orbital defects are very evident and effect the appearance and social front of the individual. Many modalities are available to rehabilitate the defect of an orbit but prosthetic rehabilitation with silicone prosthesis is a simple and effective approach. Retention is generally achieved by engaging available undercuts or using mechanical accessories or skin adhesives etc. This case report describes successful rehabilitation of right orbital defect using a non-surgical approach with room temperature vulcanized silicone and skin adhesives. Case Report: A 45 yr old male reported with, chief complaint of missing right orbit and unaesthetic appearance secondary to gunshot wound. Patient was not ready for any more surgical procedures or additional accessories and available retentive undercuts were minimal. Hence, conventional silicone prosthesis was made using stock eye shell and room temperature vulcanized silicone retained with skin adhesives. The approach was simple to a complex problem and gave reliable result in very limited time. Conclusion: With extensive orbital defect, rehabilitation is difficult and complex as retention is compromised and it is difficult to match the shade of the prosthesis.This case represents a simple and predictable approach to a case of exenterated right orbit with conventional roomtemperature vulcanized silicone and silicone skin adhesives.
