Back to Direct Style: Typed and Tight

Back to Direct Style

This paper describes the transformation of I-terms from continuation-passing style (CPS) to direct style. This transformation is the left inverse of Plotkin’s left-to-right call-by-value CPS encoding for the pure I-calculus. Not all I-terms are CPS terms, and not all CPS terms encode a left-to-right call-byvalue evaluation. These CPS terms are characterized here; they can be mapped back to dire...

Back to Direct Style II :

We continue to investigate the direct-style transformation by extending it to programs requiring call-with-current-continuation (a.k.a. call/cc). The direct style (DS) and the continuation-passing style (CPS) transformations form a Galois connection. This pair of functions has a place in the programmer's toolbox | yet we are not aware of the existence of any other DS transformer. Starting from ...

Kripke-Style models for typed lambda calculus

An Adequate, Denotational, Functional-Style Semantics for Typed FlatCurry

With the aim of putting type-based reasoning for functional logic languages, as recently explored by Christiansen et al. (2010), on a formal basis, we develop a denotational semantics for a typed core language of Curry. Dealing with the core language FlatCurry rather than with full Curry suffices, since there exists a type-preserving translation from the latter into the former. In contrast to e...

selection an appropriate leadership style to direct hospital manpower

this research has tried to find most proper leadership styles based on a approved model to direct hospital manpower appropriately. the main objective of this research was the comparison between manager’s existing leadership styles and suggested styles to them in order to direct existing styles toward suggested ones. in this cross- sectional study all qom province hospital managers participated....
