چکیده
We consider a simulation tool for the study of scheduling algorithms for real-time systems composed of periodic and aperiodic tasks. We rst introduce the scheduling problem of real-time systems, we present popular scheduling algorithms for periodic tasks with hard deadlines, and then we consider the case of mix systems, composed of periodic as well aperiodic tasks and we brieey present the various popular scheduling algorithms for these kind of systems. After that, we describe our simulation tool and deene the metrics we use to compare the performances of the various servers. In a next section, we present results of simulations and classify the aperiodic servers. In this section , we also present strategies to improve the performances of the various scheduling algorithms. Finally, we give some concluding remarks.

Time and Space Complexity Reduction of a Cryptanalysis Algorithm
Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...

متن کاملReduction of Computational Complexity in Finite State Automata Explosion of Networked System Diagnosis (RESEARCH NOTE)
This research puts forward rough finite state automata which have been represented by two variants of BDD called ROBDD and ZBDD. The proposed structures have been used in networked system diagnosis and can overcome cominatorial explosion. In implementation the CUDD - Colorado University Decision Diagrams package is used. A mathematical proof for claimed complexity are provided which shows ZBDD ...
متن کاملAn improved algorithm to reconstruct a binary tree from its inorder and postorder traversals
It is well-known that, given inorder traversal along with one of the preorder or postorder traversals of a binary tree, the tree can be determined uniquely. Several algorithms have been proposed to reconstruct a binary tree from its inorder and preorder traversals. There is one study to reconstruct a binary tree from its inorder and postorder traversals, and this algorithm takes running time of...

متن کاملA Novel Method for Detection of Epilepsy in Short and Noisy EEG Signals Using Ordinal Pattern Analysis
Introduction: In this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. Epilepsy is considered as a dynamical change in nonlinear and complex brain system. The ability of the proposed measure for characterizing the normal and epileptic EEG signals when the signal is short or is...
