102 Subrahmanyam, P.A.A new approach to specifying and handling exceptionsAn 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 handling1980

107 Subrahmanyam, P.A.An algebraic formulation of seitz's weak conditions for self timed circuitsTwo fairly intuitive conditions are given that serve to algebraically characterize Seitz's "weak conditions" for self timed circuits. It is shown that these two conditions embody the 12 temporal logic conditions (developed b y Owicki and Malachi) which are intended to express both the weak condition...Seitz's weak conditions; Self-timed circuits1982

112 Lindstrom, Gary E.Consistency and currency in functional databasesWe 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 databases1982
