Research ArticleOpen accessPhrase in the titleReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,838 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAN IN-HOUSE COMPUTER-BASED DATA ACQUISITION AND CONTROL SYSTEM FOR ANAEROBIC FERMENTATION PROCESSESE. A. Echiegu, A. E. GhalyA computer-based Data Acquisition and Control System (DACS) capable of monitoring the temperature, pH and gas production as well as maintaining a pre-determined temperature profile and feeding regime in anaerobic reactors was developed and tested.
