We present a family of parallel algorithms for simple language recognition problems involving bracket matching. The algorithms are expressed in the Bird-Meertens Formalism, exploiting only list operations which are inherently massively parallel. Our intention is to illustrate the practical eecacy with which such algorithms can be derived and expressed given the support of a well understood theo...

Supersymmetry and Yang-Mills type gauge invariance are two of the essential properties of most, and possibly the most important models in fundamental physics. Supersymmetry is nearly trivial to prove in the (traditionally gauge-noncovariant) superfield formalism, whereas the gauge-covariant formalism makes gauge invariance manifest. In 3+1dimensions, the transformation from one into the other i...

conclusions according to the results, the old dosimetry formalisms, overestimate the dose especially towards the applicator’s tip. while the tg-43u1 based software perform the calculations more accurately. results for a typical arrangement of 10 active pellets in the applicator, the percentage difference between doses obtained by the new algorithm at 1cm distance from the tip of the applicator ...

thinkers have always tried to define art with special features in the aesthetic analysis that they are common among all the artworks. but what they were suggested, for example representation and expression, is covered a part of artworks and artistic periods. formalism recommends attention to structural, perceptual and formal elements in order to overcome on these problems as a method in the ana...

Formal reasoning is notoriously long and arduous; in order to use it to reason eeectively in the construction of programs it is, therefore, paramount that we design our notations to be both clear and economical. Taking examples from AI, from imperative programming, from the use of the Bird-Meertens formalism and from category theory we demonstrate how the right choice of what to denote and how ...

How do skeptical thought experiments work? The skeptic invites us to “entertain” a vividly described possibility, then argues that skeptical conclusions follow from our inability to rule that possibility out. I contend that the argument’s soundness hinges on whether the skeptical possibilities generate legitimate doubts: we need to separate the issue of whether we can rule a possibility out fro...

The \Boom hierarchy" is a hierarchy of types that begins at the level of trees and includes lists, bags and sets. This hierarchy forms the basis for the calculus of total functions developed by Bird and Meertens, and which has become known as the \Bird-Meertens formalism". This paper describes a hierarchy of types that logically precedes the Boom hierarchy. We show how the basic operators of th...

The way we represent intentions, behaviors, and the spatial context, is crucial for any approach to mobile intention recognition. Formal grammars are cognitively comprehensible and make expressiveness properties explicit. By adding spatial domain knowledge to a grammar we can reduce parsing ambiguities. We argue that there are a number of mobile intention recognition problems which require the ...
