The thesis addresses the problem of automatic and dynamic tuning of parallel and distributed applications. Our objective is to help developers in the process of improving the application performance. The work presents a ...

Who uses requirements engineering and design methodologies besides the people who invented them? Are researchers -at least- actually trying to use them in real-world complex projects and not in "paper project"? In this p...

This essay is based on a previous “regression” testing knowledge, black box testing and user graphic interfaces testing. Besides, due to the fact that the testing life cycle is inside the software life cycle, the sug...

Chitosan is increasingly used as an alternative to synthetic polymers due to its water solubility, biodegradability, and biological activity. In this work, chitosan samples from three suppliers were evaluated and charact...

Applying design patterns is considered a helpful technique for designing software systems. Patterns description, however, results not sufficiently precise providing a weak understanding and making it difficult to be cert...

Parallel/distributed programming is a complex task that requires a high degree of expertise to fulfill the expectations of high performance computation. The Master/Worker paradigm is one of the most commonly used because...

Vision based applications are present anywhere. A special market is industry, allowing to improve product quality and to reduce manufacturing costs. The vision systems applied to industries are known as machine vision sy...

UML (Unified Modeling Language) is one of the most used languages to specify and document informatics applications. However, UML is a generalpurpose language, so it often lacks of elements to model and represent concrete...

In this work, we present an integral scheduling system for non-dedicated clusters, termed CISNE-P, which ensures the performance required by the local applications, while simultaneously allocating cluster resources to pa...

The paper provides a brief introduction into a relatively new discipline: artificial immune systems (AIS). These are computer systems exploiting the natural immune system (or NIS for brevity) metaphor: protect an organis...

Any system interacting with a data base requires modules capable of operating data stored in it. Its development times generally vary between 50 to 60 % of the time used for the application life cycle. The present paper ...

Similarity search is a fundamental operation for applications that deal with unstructured data sources. In this paper we propose a new pivot-based method for similarity search, called Sparse Spatial Selection (SSS). The...

Algorithms of the Intelligent Web is a timely and instructive book that brings together techniques for the rapidly evolving field of intelligent web applications. It covers problems such as crawling, indexing, searching,...

Web application development is a complex and time consuming process that involves di erent stakeholders (ranging from customers to developers); these applications have some unique characteristics like navigational access...

In order to measure the performance of a parallel machine, a set of application kernels as benchmarks have often been used. However, it is not always possible to characterize the performance using only benchmarks, given ...

The publication of Mobile IPv6 RFC 3775 by the IETF is a breakthrough in the data communications industry to achieve the technology convergence required by ubiquitous mobile devices. MIPv6 not only brings the possibility...
