Excerpt: CCfits necessarily works in a fundamentally different way than cfitsio. The general pattern of usage for CCfits is: create a FITS object, which either opens a disk file or creates a new disk file, create references to existing or new HDU objects within it, and manipulated the data through the references. For files with Write access the library is designed to keep the FITS object on disk in sync with the memory copy. The additional memory copy increases the resou...

Introduction: Sensor networks and other highly distributed autonomous systems cannot attain high dependability without addressing software dependability issues. Development of a system that will have a high level of reliability requires the developer to represent the system as a formal model that can be proven to be correct. Through the use of currently available tools, the model can then be automatically transformed into code with minimal or no human intervention to red...
