Operator programs and operator processes
Information and Software Technology, 2003Abstract We define a notion of program which is not a computer program but an operator program : a detailed description of actions performed and decisions taken by a human operator (computer user) performing a task to achieve a goal in a simple setting consisting of that user, one or more computers and a work environment.

Operation RUVANDIZ-SCHLUCHT (ROWANDUZ GORGE) is said to have been a detailed scheme originally submitted to Hans-Otto Wagner of Abwehr II in 1941 by Paul Leverkuehn of KONO in Istanbul for a 2–3-man parachute team to carry out the demolition of bridges on the 185 km-long, strategic asphalt road, known even today as the Hamilton Road, constructed by the

ACM Transactions on Programming Languages and Systems, 1979
Although operators, which apply to functions to produce functions, prove very useful in mathematics, they are absent from most programming languages. This paper illustrates their simplicity and power in terms of the operators of APL, and examines related constructs in other programming languages.

ACM SIGAPL APL Quote Quad, 1983
The forms in this section are referred to as operators. Operators take scalar functions as arguments and produce functions, called derived functions, as results. For example, the operator reduction takes a single dyadic scalar-function as an argument and produces a ...

Pituitary Incidentaloma: to Operate or Not to Operate ?
Acta Chirurgica Belgica, 2012The wide use of sophisticated imaging techniques has led to the discovery of asymptomatic pituitary lesions, which are called 'incidentalomas'. Their global prevalence averages 10% whereas that of macroadenomas (> 10 mm) is less than 1%. The most frequently encountered lesions are non-functioning adenomas followed by Rathke's cleft cysts.

MLQ, 2002
Operators from a Hilbert space \(H\) to itself have many applications, ranging from linear integral equations to quantum physics. Many of these applications use known properties of operators such as their spectral decomposition. Because of these applications, it is desirable to analyze when the corresponding mathematical existence theorems can be ...

Mathematical Structures in Computer Science, 1991
We define a simple collection of operations for creating and manipulating record structures, where records are intended as finite associations of values to labels. A second-order type system over these operations supports both subtyping and polymorphism.

Compelled operations and operations of degreeP
Mathematical Systems Theory, 1979We definen-ary (n ≥ 1) operations compelled by an operator and operations of degreep, generalizations of Greibach's binary syntactic operations. We show that properties of binary syntactic operators remain right forn-ary operations (n ≥ 1) and further for idempotent operations.
