TL;DR: This proposed algorithm improves the priority based CPU scheduling algorithm as obvious from simulation results.
Abstract: There are several CPU scheduling algorithms like FCFS, SRTN,RR , priority etc. Scheduling decision of these algorithms are based on parameters which are assumed to be crisp. However, in many circumstances these parameters are vague. The vagueness of these parameters suggests that scheduler should use fuzzy logic in scheduling the jobs. A fuzzy priority CPU scheduling algorithm has been proposed. This proposed algorithm improves the priority based CPU scheduling algorithm as obvious from simulation results.

TL;DR: A security model for Object Oriented Databases is presented that involves the introduction of several security concerns in object oriented databases to secure the data from unauthorized access.
Abstract: This paper presents a security model for Object Oriented Databases. The approach involves the introduction of several security concerns in object oriented databases. The access specifiers concept of object oriented programming is used in object oriented databases for security of data. This approach secures the data at physical level as well as at conceptual level. In this model three access specifiers public, private and protected are used to secure the data from unauthorized access.
