This book presents an approach based on Linux operating system, including issues such as kernel per se, units use and construction, different types of them, debugging techniques, as well as time management, interruptions, DMA (direct memory access), different buses and…

This text introduces comprehensively the reader to the distance teaching/learning process.
With this purpose, it presents a model of the Distance Education System to be used for understanding its embedded elements: contents, instructional design, communications, interaction, learning environment, and administration.

The area of multi-objective optimization is receiving increasing attention by the comunity of evolutionary computation. In this book the authors present a complete state-of-the art in the field.

The two volumes attempt to render a self-contained idea of the state of the art of cluster computing by the year 1999. In the whole, thirty-six articles are presented in Vol. 1 and twenty-nine articles in Vol.2. In each volume,…

The need for privacy has become a major priority for both governments and civilians desiring protection from signal interception. Widespread use of personal communications devices has only increased demand for a level of security on previously insecure communications. This paper…

An Image Adaptive Watermarking method based on the
Discrete Wavelet Transform is presented in this paper.
The robustness and fidelity of the proposed method are
evaluated and the method is compared to state-of-the-art
watermarking techniques available in the literature. For

Data quality is a research area strongly investigated during the 90’s. However, few companies in Argentina apply data quality methodologies or tools during the analysis, design or implementation phases of software development process. Developers generally use techniques to design systems…

Many computational applications need to look for information in a database. Nowadays, the predominance of nonconventional databases makes the similarity search (i.e., searching elements of the database that are "similar" to a given query) becomes a preponderant concept. The Spatial…

An ubiquitous computation environment has as
presupposed that the computation is in all equipment
and devices, and these are interacting between itself
and with the people. The connection between objects
and human beings is instantaneous, when these enter
in the…

Simulation is the process of executing a model, that is a representation of a system with enough detail to describe it but not too excessive. This model has a set of entities an internal state, a set of input variable…
