Any program that measures quantities from its physical environment must compute using correct and consistent units of measurement. Such a program is described here as well-measuring. In many systems, particularly embedded control software, paying inadequate attention to units of measurement can result in catastrophe. Unfortunately, current programming languages and tools provide little aid to the programmer attempting to establish or verify the well-measuring property. We present a program analysis technique for inferring and checking the units used within a program. The technique combines traditional Hindley-Milner-style type inference with the use of Static Single Assignment (SSA) form to
enable analysis of imperative programs.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
