Research ArticleOpen accessIn the abstractRedundancy Schemes for High Availability Computer ClustersChristian K. Bassek, Samuel Pierre, Alejandro QuinteroThe primary goal of computer clusters is to improve computing performances by taking advantage of the parallelism they intrinsically provide. Moreover, their use of redundant hardware components enables them to offer high availability services. In this paper, we present an analytical model for analyzing redundancy schemes and their impact on the cluster’s overall performance. Furthermore, several cluster redundancy techniques are … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperiment of Tamper Detection and Recovery Watermarking in Picture Archiving and Communication SystemsSiau-Chuin Liew, Jasni Mohamad ZainProblem statement: Medical images such as x-rays, ultrasounds and Magnetic Resonance Imaging (MRI) plays an important role in helping the physicians to diagnose a disease or body conditions. These images can be tampered with existing image processing tools that is easily available. The usage of security measures such as watermarking can protect the integrity of the images.

Review ArticleOpen accessAll words, across the recordA Survey of Quadratization Methods Used in QUBO Formulations and their Usage in Quantum and Digital AnnealingGeethika Prabhath, Anuradha Mahasinghe, Nalin Ranasinghe, Kasun De ZoysaQuantum annealing is a metaheuristic method aimed at finding the global minimum of a pseudo-Boolean quadratic function. To solve a problem by a quantum annealer, it must be restated as a QUBO (quadratic unconstrained binary optimization) problem, the standard format acceptable to an annealer. However, there are many natural problems that turn out be of cubic or higher order, yet … …Journal of Computer Science, Vol. 22, Issue 1 · 16 Feb 2026 · 2,554 accessesView PDFCite
