List of computer algebra systems. The following tables provide a comparison of computer algebra systems (CAS). A CAS is a package comprising a set of algorithms for performing symbolic manipulations on algebraic objects, a language to implement them, and an environment in which to use the language. A CAS may include a user interface and graphics capability; and to be effective may require a large library of algorithms, efficient data structures and a fast kernel.
Next >>. Deduplication Ratio is the ratio of data prior to deduplication to that of after deduplication. The deduplication ratio report shows the percentage of deduplication that has been realized system-wide. This report can be filtered to specific cloud accounts to see how effective deduplication has been for volumes assigned to those particular cloud storage accounts. Since the appliance performs deduplication across volumes within a cloud account, it is not possible to filter this view onto specific volumes.
Dependency ratio. In economics, geography, demography and Sociology the dependency ratio is an age-population ratio of those typically not in the labor force (the dependent part ages 0 to 14 and 65+) and those typically in the labor force (the productive part ages 15 to 64). It is used to measure the pressure on productive population.
