Abstract
The XPRESS project introduces a completely new scalable concept of a manufactronic networked factory, which is composed by a co-ordinated team of specialized autonomous objects (Manufactrons), each knowing how to do a certain process optimally. This knowledge based concept integrated the complete chain: production configuration (decrease of ramp-up time of at least 50%), multi-variant production line (varying types and volumes on a single line) and 100% quality monitoring. The manufactronic networked architecture allows continuous process improvement, and will be able to anticipate and to respond to rapidly changing consumer needs, producing high-quality products in adequate quantities while reducing costs. This concept is demonstrated in the automotive, aeronautics and electrical industry but can be transferred to nearly all production processes.

Abstract
In this paper, we propose an architecture based on three layers (infrastructure, server hardware and operating system, and business applications) for a unified communications solutions exclusively sustained on open source technologies and open standards. Additionally, we discuss the importance of open standards and open source in a fully integrated communications solution, exposing some factors that a company should consider when choosing open source software.

Abstract
Purpose: The goal of XPRESS is to establish a breakthrough for the factory of the future with a new flexible production concept based on the generic idea of "specialized intelligent process units" ("Manufactrons") integrated in cross-sectoral learning networks for a customized production. XPRESS meets the challenge to integrate intelligence and flexibility at the "highest" level of the production control system as well as at the "lowest" level of the singular machine. Design/methodology/approach: Architecture of a manufactronic networked factory is presented, making it possible to generate particular manufactrons for the specific tasks, based on the automatic analysis of its required features. Findings: The manufactronic factory concept meets the challenge to integrate intelligence and flexibility at the "highest" level of the production control system as well as at the "lowest" level of the singular machine. The quality assurance system provided a 100% inline quality monitoring, destructive costs reduced 30%-49%, the ramp-up time for the set-up of production lines decreased up to 50% and the changeover time decreased up to 80%. Research limitations/implications: Specific features of the designed manufactronic architecture, namely the transport manufactrons, have been tested as separate mechanisms which can be merged into the final comprehensive at a later stage.Practical implications: This concept is demonstrated in the automotive and aeronautics industries, but can be easily transferred to nearly all production processes. Using the manufactronic approach, industrial players will be able to anticipate and to respond to rapidly changing consumer needs, producing high-quality products in adequate quantities while reducing costs. Originality/value: Assembly units composed of manufactrons can flexibly perform varying types of complex tasks, whereas today this is limited to a few pre-defined tasks. Additionally, radical innovations of the manufactronic networked factory include the knowledge and responsibility segregation and trans-sectoral process learning in specialist knowledge networks.

Abstract
This paper looks to the semantic web and Web 3.0 technologies as an enabler for the creation of value and new emergent business models. It describes the concept of Web 3.0, its properties and its major differences in relation with previous Web 2.0 concept. Furthermore, the paper proposes eight business models that a company can follow to adopt a successful Web 3.0 business strategy. © 2011 AISTI.

Abstract
Internet Banking has emerged as one of the most remarkable and profitable ecommerce applications over the last decade. The home banking is a service that allows new ways of interaction with customers, turning possible to overcome the barriers of distance between bank institutions and their clients. Despite the increasing importance of home banking, very few studies were made in the Portuguese context and, therefore, very little are known about the profile of users of this service particularly in some specific domains. This paper has the objective to show the results of our study considering the use of Internet Banking among Portuguese college students contextualized with other existing studies/publications and performing a critical analysis from the obtained results. We realized that the large majority of students use Internet Banking, consider the service safe, adopt it essentially for money movements and have a strong perception that bank institutions adopts anti-frauds mechanisms. Additionally, our study demonstrated that there is a strong association between the simultaneously use of home banking and MBNet services, and we realized that the user perception about the safety of Internet Banking increases with the use of these services. © Filipe Moreira, Pedro Rocha and Fernando Almeida, 2012.

SISTEMAS E TECHNOLOGIAS DE INFORMACAO: ACTAS DA 4A CONFERENCIA IBERICA DE SISTEMAS E TECNOLOGIAS DE LA INFORMACAO
Abstract
Unified Communications (UC) have the potential to dramatically simplify and improve enterprise communications, reducing costs and improving revenue opportunities. This paper proposes an architecture of three layers for a UC solution based on open source technologies and open standards. The Infrastructure layer is responsible for the physical IP infrastructure network, the Server Hardware and Operating System layer includes the back-end operating system and server services that can be used by the UC platform and the Business Applications layer integrates the UC with other external applications. Finally, the paper presents the major benefits of UC solutions, giving a special emphasis to the benefits derived for the use of a standards-based I P communications.
