Subrahmanyam, P.A. | A new approach to specifying and handling exceptions | An operation generally exhibits different patterns of behavior over different parts of its domain. Depending upon the context, such behavior may either be conceived of as "normal" or as an "exception." Thus, the behavior of an operation Is quite naturally characterized by the set of partial operatio... | Computer operations; Exceptions; Exception handling | 1980 |

Lindstrom, Gary E. | Consistency and currency in functional databases | We consider a hybrid model of databases, in which a functional component T is defined as an extension to an imperative component B. T. is loosely coupled to B through a highly parallel function network N. which provides a simple failsafe test of whether an existing assignment of values to a given vi... | Functional databases | 1982 |

Organick, Elliott I. | ADA to silicon transformations: the outline of a method | This report explores the contention that a high-order language specification of a machine (such as an Ada program) can be methodically transformed into a hardware representation of that machine.
