Much Learning is done by way of studying precedents and exercises. A teacher supplies a story, gives a problem, and expects a student both to solve a problem and to discover a principle. The student must find the correspondence between…

This paper presents a novel algorithm for learning in a class of stochastic Markov decision processes (MDPs) with continuous state and action spaces that trades speed for accuracy. A transform of the stochastic MDP into a deterministic one is presented…

and (ii) the derived state of the breeding (rather than winter) ecological niches of each species., The evolution of migration has long been considered complex and recent work has demonstrated additional complexity: some species follow the same ecological conditions throughout…

Knowledge of the distribution of soil organic matter (SOM) fractions is important in managing soils toward a sustainable agricultural system ina tropical environment, However, data on Histosols in limited. This study developed 19 regions of Brazil. Soil organic matter was…

There has been a lot of research addressing the relationship between Information Technology (IT) investments and
productivity. Most of the work has been based on firm-level metrics such as total IT investment. We present what
we believe is…

How can we insure that knowledge embedded in a program is applied effectively? Traditionally the answer to this question has been sought in different problem solving paradigms and in different approaches to encoding and indexing knowledge. Each of these is…

Introducción. En la actualidad, el uso de las TIC en el Espacio Europeo de Educación Superior se ha convertido en un tema estrella. Una de las universidades que mayor énfasis va a poner en su utilización es la universidad a…

This dissertation investigates changes that occurred in architectural culture in respect to conditions of modernity. Large-scale industrialization and urbanization caused dramatic ruptures with traditional social and economic hierarchies, forcing a reconceptualization of the theoretical constructs underlying architecture. During the course…

In this paper, we build on previous work on Belief Revision operators based on the use of logic programming with Answer Set semantics as a representation language. We present a set of postulates for Answer Set Revision with respect to…

Un objectif principal du génie logiciel est de pouvoir produire des logiciels complexes,
de grande taille et fiables en un temps raisonnable. La technologie orientée objet (OO) a fourni de bons concepts et des techniques de modélisation et de programmation…
