Heterogeneous azeotropic distillation is a widely used technique to separate binary azeotropic mixtures into their components. One of its most important applications is the dehydration of ethanol, which is blended with gasoline to obtain automobile fuel. Among all the compounds…

Design and optimization of distillation columns for ethanol dehydration, using a hydrocarbon as entrainer, implies a good knowledge of vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid equilibrium (VLLE). Chemical process simulation programs always require the use of a thermodynamic model that…

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

The present paper is about applying competence modeling for a knowledge engineer in the case of the company WBSA Sistemas Inteligentes S.A. The process was based on Lucia and Lepsinger model, by which competences are characterized through the identification of…

The Knowledge Engineering Suite is an ontology production method, based on relationship networks, for knowledge representation inside specific contexts. The production of these ontologies has three basic steps, since catching the client data, knowledge base creation, and information retrieval and…

The role of communities associated to a substrate as fundamental components of an aquatic system has been recognized by many authors. Although periphyton has been considered of great importance in shallow lakes, its inclusion in different ecological models has been…

Este trabajo pretende contribuir, desde una perspectiva histórico demográfica, al conocimiento del sector indígena de la población rionegrina ubicada en el ámbito mesetario extendido al sur de los ríos Limay y Negro, entre 1885 y 1920. En el marco del…

Este artículo se propone sintetizar las principales ideas de las ponencias presentadas en la Mesa de Trabajo “Los problemas de las Gimnasias” que se desarrolló en el marco del 9° Congreso Argentino y 4° Latinoamericano de Educación Física y Ciencias…

Este trabajo pretende ser una contribución al conocimiento de las sociedades prehispánicas del Noroeste argentino entre el 1000 d.C. y el 1536 d.C. El objetivo es caracterizar la tecnología lítica entendida como un fenómeno multidimensional sustentado en las relaciones sociales.…

Intelligent computing systems comprising microprocessor cores, memory and reconfigurable user-programmable logic represent a promising technology which is well-suited for applications such as digital signal and image processing, cryptography and encryption, etc. These applications employ frequently recursive algorithms which are particularly…
