The paper is a basis for multiagent visual computing with the Morph Gentzen logic. A basis to VR computing, computational illusion, and virtual ontology is presented. The IM_BID model is introduced for planning, spatial ...

Component-based Development is a challenging paradigm, though Pervasive Computing Environments, as a special case of such systems, carry even more complications. Applications must be kept available for users anytime, an...

In this thesis, parallel computing on installed local area networks (LAN) is focused, analyzing problems and possible solutions taking into account the main factors of computing and communications. More specifically, LAN...

Wildland fires are a critical natural hazard in many regions of the World. Every year, millions of hectares are burned in Tropical, Boreal and Mediterranean forest, which causes a wide variety of effects, from atmospheri...

The problem of speeding up ínference has proved to be important in argumentative systems. When computing dialectical structures, several paths are searched (called argumentation lines), many of which will eventually pro...

Despite the advances in wireless, energy-constrained ad hoc networks, there are still many challenges given the limited capabilities of the current hardware. Therefore, our aim is to develop a lightweight, yet powerful o...

From the many different patterns that can be extracted from data, so-called emerging patterns (EPs) are a particular useful kind. EPs are itemsets whose supports increase significantly from one dataset to another. Existi...

The N-body problem is often characterized by the necessity to interact each of the N bodies with every other one. Its principal problem is the time spent in force computation. Computing the force among a set of N bodies...

Este trabalho descreve o sistema de software Laboratório de Alta Exatidão e Alto Desempenho, desenvolvido para resolução de problemas da computação científica com verificação automática do resultado. O sistema ...

We present in this paper a clustering algorithm which is based on a cellular automaton and which aims at displaying a map of web pages. We describe the main principles of methods that build such maps, and the main princi...

In this paper, an improvement of deformable template matching algorithm for polygonal objects in grayscale images using two-dimensional deformable templates along orthogonal curves is presented. In the process of pre-com...

Parallel performance optimization is being applied and further improvements are studied for parallel linear algebra on clusters. Several parallelization guidelines have been defined and are being used on single clusters ...

We extend the regular model checking framework so that it can handle systems with arbitrary width tree-like structures. Con gurations of a system are represented by trees of arbitrary arities, sets of con gurations are r...

Meeting user requirements of a software system has been a major challenge to software developers. Experience in a number of large projects reveals that a very large percentage of errors were made at the earlier stages o...

In this work the pipeline theory applied to computing systems is reviewed. The effects of the stage delay, overhead stage delay, equalization factor and number of stages on the pipeline system performance are analyzed. A...

As a new promising crossover method, multiple crossovers per couple (MCPC) deserves special attention in evolutionary computing field. Allowing multiple crossovers per couple on a selected pair of parents provided an ext...

This paper describes activities developed in Argentina between 1956 and 1966 related to the computer and that were coincident with the arrival of the first machines in the country. It deals, particularly, with the work o...

1957 marked the beginning of modern education in computing in Argentina. I was lucky enough to live this part of the history. After issuing an international bid that year, all members of a special commission from the Uni...

The paper presents a formal model for a knowledge repository shared by members of a Virtual Community of Practice (VCPs), describes how the repository can be used to underpin collaborative problem solving, and how to bui...

The subject matter of this work is focused in the development of an application for team work over a distributed system belonging to an organization. This choice is based in the organizations need of their members’ co...

Interesting real world combinatorial problems are NP-complete and many of them are hard to solve by using traditional methods. However, several heuristic methods have been developed in order to obtain timely suboptimal s...
