The great variety of excipients to which we have access thanks the globalization gives rise to the necessity to evaluate their functionality, currently the pharmaceutical performance of croscarmellose and carmacel as tab...

This book presents the contents of an introduction course to Computer Science for engineering disciplines where the engineer makes use of the computer not only as an "office tool" but also as an integral part of his desi...

Domotics systems are intelligent systems for houses and apartments to control several issues as security and light or climate devices. In this work we present the development of an economic domotic system to control diff...

This paper describes an approach to On Line Analytical Processing (OLAP), expresed in the declarative programming paradigm. We define a collection of functions that capture some of the functionality currently provided b...

The need for improving software processes approximated the software engineering and artificial intelligence areas. Artificial intelligence techniques have been used as a support to software development processes, particu...

At present, the early phase of Requirements Engineering is a new research area in the Software Engineering field. This phase is concerned with the analysis of the organizational context in which a software system will be...

Nowadays, the digital circuit production is carried out specifying the circuit functionality using a hardware description language. Then, this specification is synthesized down to a structural netlist suitable for use by...

El orden de palabras constituye uno de los problemas de la sintaxis del español estudiado desde distintas perspectivas en los últimos años (Contreras, 1978; Silva Corvalán, 1984; Narbona Jiménez, 1996; Morris, 1998;...

En la actualidad la propuesta MDA está tomando cada vez más fuerza en el desarrollo de software. En los últimos años han ido apareciendo numerosas herramientas que dan soporte a esta propuesta, facilitando la tarea d...

El sitio Calera se localiza en las Sierras Bayas, partido de Olavarría. Estaba conformado por una serie de rasgos que se denominaron cubetas (n=4), correspondientes a pozos de dimensiones variables excavados intencional...

Las Ferias artesanales se instalan en la Ciudad de Buenos Aires hacia fines de la década del 60. Allí se exhiben y expenden artículos donde prima la tradición urbana constituida mayoritariamente por elementos de orig...

Asumiendo que uno de los objetivos de los sitios web municipales es incrementar la calidad de los servicios prestados a sus ciudadanos, este paper analiza los aspectos que permitirán a estos sitios, alcanzar un grado de...

In the last years software researchers have been looking for ways of assembling systems in a style of software construction similar to “LEGO blocks”. Software components are reusable building blocks for constructing ...

This paper sets out to provide a highly automated mechanism for an undo process that can be easily built into a new or existing system. Our proposal is based on the observation that it is not necessary to store the state...

The appearance and continuous growth of virtual communities on the web imposes the challenge of coping with the large amount of information and knowledge these communities produce. The Semantic Web with its set of standa...

Public key cryptography has been contributed some important functionality to computer systems security. Each pubic key scheme is based in some mathematics or computational problem, easy to solve in one way (an intended r...

La investigación se desarrolla en el marco de un proyecto mayor que abarca el estudio arqueológico y etnohistórico de la dominación incaica en el Centro-Oeste Argentino. Los avances de los estudios permiten establec...

There are some concepts, such as synchronization, error checking, distribution, security, and others, that are dissimilar from the basic functionality of a system, and they are not correct encapsulated when using traditi...

The main objective of this paper centers on reviewing the evolution of Decision Support System´s (DSS) architectures, particularly as they apply to natural resources. Today it is difficult to conceive the existence of a...

Different types of middleware exist to facilitate the integration of software running on heterogeneous computing platforms. Message Oriented Middleware (MOM), for instance, enables the interaction between heterogeneous a...

Software engineering has entered a new era, the Internet and its associated technologies require a different conceptual framework for building and understanding software solutions. Users ask to develop applications more...

En este trabajo se propone un modelo para interpretar la historia del aprovechamiento de las materias primas óseas en Tierra del Fuego. Este modelo pretende ser un primer intento de aplicar conceptos relaciones con la T...

Desde que fue definido, el protocolo TCP se ha adaptado a un número considerable de cambios en su medioambiente de operación: definido en momentos en que la red subyacente estaba compuesta de vínculos homogéneos y po...
