Syntactic Definitions of Undefined: On Defining the Undefined
In the A-calculus, there is a standard notion of what terms should be considered to be "undefined": the unsolvable terms. There are various equivalent characterisations of this property of terms. We attempt to find a similar notion for orthogonal term rewrite systems. We find that in general the properties of terms analogous to the various characterisations of solvabil-ity differ. We give two a...
متن کاملAvoiding the Undefined by Underspecification
The first volume of Springer-Verlag's Lecture Notes in Computer Science appeared in 1973, almost 22 years ago. The field has learned a lot about computing since then, and in doing so it has leaned on and supported advances in other fields. In this paper, we discuss an aspect of one of these fields that has been explored by computer scientists, handling undefined terms in formal logic. Logicians...
متن کاملUndefined cellulase formulations hinder scientific reproducibility
In the shadow of a burgeoning biomass-to-fuels industry, biological conversion of lignocellulose to fermentable sugars in a cost-effective manner is key to the success of second-generation and advanced biofuel production. For the effective comparison of one cellulase preparation to another, cellulase assays are typically carried out with one or more engineered cellulase formulations or natural ...
متن کاملAdapting Calculational Logic to the Undefined
Programming abounds with partial functions. Some functions are inherently partial (e.g. division and referring to the first element of a list). Other functions are partial according to their recursive definitions. If partial functions are admitted in formulae, a programming logic is needed that handles partial functions and undefined terms. Dijkstra and Scholten [1], Gries and Schneider [2], Fe...

This paper presents an application of computer The implementation and operation of the system is vision in a real-world uncontrolled environment found at BHP Steel Port Kembla. The task is visual identification of torpedo ladles at a Blast Furnace wlahdilceh. is achieved by reading numbers attached to each 3. IMPLEMENTATION Number recognition is achieved through use of feature extraction using ...
