Nowadays Peer-to-Peer (P2P) systems became an important part of Internet, millions of users have been attracted to use their structures and services. The popularity of Peer-to-Peer systems speed up academic research join...

Such as the author states in the first pages, this book is the result of several years of teaching the involved topics at the California Polytechnic State University (Cal Poly), San Luis Obispo, California, U.S.A, to und...

Resumen de la tesis del autor para obtener el grado de Magister en Redes de Datos de la Facultad de Informática de la UNLP, dirigida por Luis Armando Marrone. Es revisión de: http://sedici.unlp.edu.ar/handle/10915/4107...

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...

The objective of present study was to improve gastric residence time of furazolidone by preparing mucoadhesive Multiple Unit Systems (MUS) with chitosan, Hydroxypropyl methyl cellulose K4M and sodium carboxymethyl cellul...

The main goal of this thesis was to design new parallel processing strategies specially conceived for distributed environments in order to solve numerical and structural problems from the field of process systems enginee...

Providing Quality of Service (QoS) in Video on Demand systems (VoD) is a challenging problem. In this paper, we analyse the fault tolerance on a P2P multicast delivery scheme, called Patch Collaboration Manager / Multica...

The exponential periodicity and stability of continuous nonlinear neural networks with variable coefficients and distributed delays are investigated via employing Young inequality technique and Lyapunov method. Some new...

Migration of individuals allows a fruitful interaction between subpopulations in the island model, a well known distributed approach for evolutionary computing, where separate subpopulations evolve in parallel. This mode...

In this paper we show an algorithm for dynamic reconfiguration of distributed applications based on the mobile agent model. We also show that the proposed algorithm can be easily implemented in the IPL language, a langua...

We propose a distributed solution for the group mutual exclusion problem based on priorities, in a network with no share memory whose members only communicate by messages. The proposed algorithm is composed by two player...

Esta tesis trata sobre qué son los Web Services, la tecnología que es necesaria para su implementación y el uso de protocolos standards. Se incluyen algunos capítulos para ver como enfrentan el tema grandes empresas ...

Celsius es una herramienta de software que permite gestionar solicitudes de información bibliográfica y ayuda a coordinar el trabajo de los equipos encargados de atenderlas; también facilita la realización búsquedas...

Deadlock detection is one of the most discussed problems in the literature. Although several al- gorithms have been proposed, the problem is still open. In general, the correct operation of an algorithm depends on the re...

La arquitectura cliente/servidor ha provocado un profundo cambio de paradigmas en la industria informática. Está reemplazando a las aplicaciones monolíticas de los mainframes por otras que están organizadas en un esq...

Se ha definido el desarrollo de un sistema integrado de hardware y software para la detección en tiempo real del corte de cables telefónicos y el comando de las acciones preventivas- correctivas correspondientes. En es...

Este trabajo de grado propone un modelo para la construcción de sistemas con arquitecturas de tres capas en el contexto del paradigma de orientación a objetos. La tecnología de orientación a objetos tiene más de 25 ...

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel perfor-mance against the local interactive...

Agents repesent a new paradigm for developing software applications. In spite of the interest of this particular way of looking at problems, there is considerable discrepancy on exactly what is an agent and which are the...

Fast response, storage efficiency, fault tolerance and graceful degradation in face of scarce or spurious inputs make neural networks appropiate tools for Intelligent Computer Systems. But on the other hand, learning alg...

The computational resources need by the scientific community to solve problems is beyond the current available infrastructure. Performance requirements are needed due constant research progress, new problems studies or d...

RDF has seen increased adoption in recent years, prompting the standardization of the SPARQL query language for RDF, and the development of local and distributed engines for processing SPARQL queries. This survey paper p...

In the present study, we sought to systemically evaluate the biodistribution and the tumor-accumulation of N-succinyl-chitosan nanoparticles (Suc-Chi-NPs, 200 nm in diameter) in model tumor-bearing mice and also the bind...

Los radicales libres producen efectos dañinos sobre las moléculas diana, como una incrementada peroxidación de lípidos (PL), proteínas y del ADN, lo cual puede ser inhibido o reducido por sustancias antioxidantes. E...
