An Inductive Theorem on the Correctness of General Recursive Programs
(Oxford University Press, 2007)We prove a relatively simple inductive theorem (analogous to Floyd and Dijkstra's Invariance Theorem for iterative programs) to verify the correctness of an ample class of non-deterministic general recursive programs. This ... -
Intuitionistic Logic according to Dijkstra’s Calculus of Equational Deduction
(University of Notre Dame, 2008)Dijkstra and Scholten have proposed a formalization of classical predicate logic on a novel deductive system as an alternative to Hilbert’s style of proof and Gentzen’s deductive systems. In this context we call it CED ... -
Bioescenarios III.
(Asociación Colombiana de Ingenieros de Sistemas (ACIS)Colombia, 2008)El uso de las tendencias bioinspiradas en el desarrollo de soluciones informáticas se está imponiendo en el mundo por ser una opción en el tratamiento de problemas complejos. En Colombia se están realizando los primeros ... -
Theorem Proving Modulo Based on Boolean Equational Procedures
(Springer, 2008)Deduction with inference rules modulo computation rules plays an important role in automated deduction as an effective method for scaling up. We present four equational theories that are isomorphic to the traditional Boolean ... -
Mediation System for cooperative activities: knowledge system design
(WSEAS, 2008)In this article we present the use the knowledge for a Mediation System, developed to give support to mechanical system designer activities. The use of cooperative systems must contain a sufficient level of assistance to ... -
An elementary and unified approach to program correctness
(Springer, 2009)We present through the algorithmic language DHL (Dijkstra-Hehner language), a practical approach to a simple first order theory based on calculational logic, unifying Hoare and Dijkstra’s iterative style of programming ... -
La inteligencia de negocios, un concepto informático
(ACISColombia, 2009)Diferente a lo que podría esperarse, el concepto de Business Intelligence no es un resultado de desarrollos en el mundo de las Ciencias Administrativas, sino que es un producto del progreso de la Informática o de ... -
Sistema de extracción de cuerpos de texto de la web para tareas lingüísticas
(ScieloColombia, 2009)En este artículo se describe un sistema desarrollado para la extracción de grandes cuerpos de texto de Internet, teniendo como motivación el valor que ofrecen los ejemplos de lenguaje natural disponibles en la red para ... -
AIDE À LA CONCEPTION COLLABORATIVE. UN SYSTEME DE MEDIATION POUR L'USAGE DE MICRO- OUTILS LOGICIELS
(In CognitoFrance, 2009)Nous présentons, dans cet article, deux concepts pour améliorer l'assistance à la coopération en conception de systèmes mécaniques : 1) le concept de micro-outils développé pour assister l'activité elle-même des concepteurs ... -
Agent-Based Mediation System to Facilitate Cooperation in Distributed Design
(WSEASE.E.U.U., 2009)In this article we present the use of knowledge for a Mediation System, developed to give support to participants in mechanical-system-designer activities. To use a cooperative system sufficient assistance is needed to ... -
A Graphical Environment for the Semantic Validation of a Plan Execution Language
(© Copyright 2021 IEEEUSA., 2009)This paper presents PLEXIL5, PLEXIL's formal interacting visual environment, a graphical environment providing an user-friendly interface to the formal operational semantics of PLEXIL. PLEXIL is a synchronous plan execution ... -
Bioescenarios IV Inteligencia de enjambres: optimización por cúmulos de partículas
(Asociación Colombiana de Ingenieros de Sistemas (ACIS)Colombia, 2010)Conocer técnicas como las de los algoritmos bioinspirados, que han mostrado simplicidad y eficiencia en la solución de problemas complejos, es útil para los Ingenieros de Sistemas. Bioescenarios IV crea modelos para el ... -
Constructors, Sufficient Completeness, and Deadlock Freedom of Rewrite Theories
(SpringerBerlín, 2010)Sufficient completeness has been throughly studied for equational specifications, where function symbols are classified into constructors and defined symbols. But what should sufficient completeness mean for a rewrite ... -
Rewriting Logic Semantics of a Plan Execution Language
(E.E.U.U., 2010)The Plan Execution Interchange Language (PLEXIL) is a synchronous language developed by NASA to support autonomous spacecraft operations. In this paper, we propose a rewriting logic semantics of PLEXIL in Maude, a ... -
Comunidades 2.0
(Asociación Colombiana de Ingenieros de Sistemas (ACIS)Colombia, 2010-10)La generación de herramientas llamada Web 2.0 está transformando la manera de comunicarnos, aprender y trabajar. Específicamente ha permitido la conformación de las llamadas Comunidades 2.0 auto organizadas de manera ... -
Simulation and Verification of Synchronous Set Relations in Rewriting Logic
(NASA Langley Research CenterHampton, Virginia., 2011)This paper presents a mathematical foundation and a rewriting logic infrastructure for the execution and property verification of synchronous set relations. The mathematical foundation is given in the language of abstract ... -
Towards a Maude Formal Environment
(SpringerBerlín, 2011)Maude is a declarative and reflective language based on rewriting logic in which computation corresponds to efficient deduction by rewriting. Because of its reflective capabilities, Maude has been useful as a metatool in ... -
A mediation system to facilitate cooperation in a co-design platform
(IEEE XploreUSA., 2011)We present a mediation system, developed to give support to participants in mechanical-system-designer activities. Sufficient assistance is needed to facilitate and coordinate actors' activities. To accomplish this goal ... -
A formal library of set relations and its application to synchronous languages
(Elsevier B.V., 2011)Set relations are particularly suitable for specifying the small-step operational semantics of synchronous languages. In this paper, a formal library of set relations for the definition, verification of properties, and ... -
