XML as a basis for interoperability in Real Time Distributed Systems

Many real time applications consist of components that can situate in a centralized/distributed environment. Typically due to different system requirements these components could be developed in different technologies which require a bridge for communication. With the increasing popularity of XML, it has become an alternative solution for data exchange in the real time application domain. XML has become the most important mechanism for data exchange between heterogeneous data sources. This paper presents a methodology for real time application data in XML. By defining a solid XML schema for the real time domain attributes, applications from diverse platforms can be based on the data definition and create instances of XML documents to exchange data

Resource Modeling for Embedded Systems Design

The paper describes a formal framework for designing and reasoning about resource-constrained embedded systems. The framework is based on a series of process algebraic formalisms which have been previously developed to describe and analyze various aspects of real-time concurrent systems. We present a uniform framework for formal treatment of resources and illustrate modeling of common resource classes

A ubiquidade e a contextualização no acesso à informação e serviços turísticos

Com a distinção da região do Alto Douro Vinhateiro a Património da Humanidade, na categoria de Paisagem Cultural, em dezembro de 2001, a região teve eco internacional, alcançando nova visibilidade. A natureza pristina convida o visitante a conhecer todo este património, transformando-o num recurso turístico que necessita de ser explicado e/ou interpretado (a história, as tradições, os artefactos, a arte, entre outros) de forma célere assente no pressuposto da ubiquidade de acesso à informação

How pervasive and mobile computing can help organizations to include people with visual disabilities on their client-approach strategy?

Organizations have in-built social responsibility to society. The evolution of technology have enable organizations to interact in an innovatively and more close approach to their clients. But this evolution has not included people with special needs like blind people. And, even those organizations that have enable some kind of support-approach to blind people, have typically disjointed, incomplete and typically parallel approaches; compared to their massclient standard approach. This paper discusses the potential of Pervasive and Mobile Computing to support, not just an innovative and unified approach, but also a real possibility of promoting real inclusion of blind people in what concerns to the delivery of information and services organizations offer. This paper also represents a reflection and a mind shaking attempt, while the authors are working in allowing blind people an autonomous buying process, in hypermarkets, supported by the use of wireless networks and modern mobile devices, with multiple technologies support, like Wi-Fi and inertial and magnetic sensors
