On the implementation of security measures in information systems [PDF]

open access: yesCommunications of the ACM, 1972
The security of an information system may be represented by a model matrix whose elements are decision rules and whose row and column indices are users and data items respectively. A set of four functions is used to access this matrix at translation and execution time.

Units of Measure in Clinical Information Systems [PDF]

open access: yesJournal of the American Medical Informatics Association, 1999
The authors surveyed existing standard codes for units of measures, such as ISO 2955, ANSI X3.50, and Health Level 7's ISO+. Because these standards specify only the character representation of units, the authors developed a semantic model for units based on dimensional analysis.

Robustness and Informativeness of Systemic Risk Measures [PDF]

open access: yesSSRN Electronic Journal, 2013
Recent literature has proposed new methods for measuring the systemic risk of financial institutions based on observed stock returns. In this paper we examine the reliability and robustness of such risk measures, focusing on CoVaR, marginal expected shortfall, and option-based tail risk estimates.
