Research ArticleOpen accessAll words, across the recordRandomness Analysis of DES Ciphers Produced with Various Dynamic ArrangementsMalik Qasaimeh, Raad S. Al-QassasOver the past few years, researchers have devoted efforts to enhance the original DES encryption algorithm. These enhancements focus on improving multiple perspectives of the algorithm through enhancing its internal components to deliver a robust DES variant against different kinds of typical attacks such as linear and differential crypto analysis, in addition to the newly evolved attacks such as differential … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 7,161 accessesView PDFCite

SeethalakshmiProblem statement: As distributed real-time multimedia services are accessed by users from different locations, the run-time performance must be managed and monitored to get a clear view of how media web services perform within their operational environments and to perform control actions to modify and adjust the their behavior. Otherwise it will provide negative effects on the reputation of service … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,188 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Possibility of Cyclical Behavior in a Class of Dynamic ModelsAnjan MukherjiThe study investigates conditions under which endogenous cyclic behavior may be observed within the context of Predator-Prey (Lotka-Volterra) Models. The analysis also establishes conditions under which such behavior is non-existent and hence establishes conditions for global convergence to the interior equilibrium, whenever it exists. The results are then applied to two diverse sets of economic exercises and shows how the … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 9 Dec 2005 · 7,600 accessesView PDFCite
