In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

Direct analysis of failures from the field of application is an effective practice to understand the actual dependability behavior of an operational system. However, despite its wide use over the last four decades on a large variety of systems, field data analysis has rarely been applied to wireless networks. Users accessing the Internet ubiquitously through these networks are increasing, and t...

Expectations to derive value from open data are high. However, how is created still largely unknown. Open usually generated in constellation of actors which each player has different capabilities and roles. To understand the creation process, business model canvas introduced this article. The typical components derived literature. By combining these two research streams, created. case Coronavir...

Various user groups at the University of Leipzig use microarray technology (mainly from Affymetrix Inc.) for gene expression analysis in their research and are producing several hundreds of experiment a year. To manage the large amounts of data resulting from these experiments, a comprehensive database solution is necessary, in particular to store raw microarray data as well as derived data and...
