Oversubscribing Inotify On Embedded Platforms, Donald Percivalle, Scott Vanderlind

Computer Engineering

For most computers running the popular Linux operating system, the inte- grated kernel component inotify provides adequate functionality for monitor- ing changes to files present on the filesystem. However, for certain embedded platforms where resources are very limited and filesystems are very populated (like network attached storage (NAS) devices), inotify may not have enough resources to provide watchers for every file. This results in applications missing change notifications for files they have watched. This paper explores methods for using inotify most effectively on embedded systems by leveraging more la- tent storage. Benefits of this include a reduction in dropped notifications …

Rest Api To Access And Manage Geospatial Pipeline Integrity Data, Alexandra Michelle Francis

Master's Theses

Today’s economy and infrastructure is dependent on raw natural resources, like crude oil and natural gases, that are optimally transported through a net- work of hundreds of thousands of miles of pipelines throughout America[28]. A damaged pipe can negatively a↵ect thousands of homes and businesses so it is vital that they are monitored and quickly repaired[1]. Ideally, pipeline operators are able to detect damages before they occur, but ensuring the in- tegrity of the vast amount of pipes is unrealistic and would take an impractical amount of time and manpower[1].

Natural disasters, like earthquakes, as well as construction are just …
