    The aim of this paper is to present a cloudlet architecture for dashboard in Cloud and Ubiquitous Manufacturing. In practice means that, with Cloud Computing adoption, Manufacturing requires management applications where ubiquity and effectiveness are enabled. If ubiquity and resources scalability, availability and capacity can be well supported by cloud, pragmatics instruments are required to support effectiveness. The architecture here presented shows the integration of enriched existing (cloud) services, as instances of resources, with layers of new services towards direct and synchronous communication between users. These Rich Internet Application (RIA) components, here named cloudlets, integration, follow dashboards organization patterns and will be supported by emergent web3.0 interaction technologies. In fact, the paper proposes a new Presentation Layer to be used in UMS and (that may be used) in any multi-layer cloud-based web application. (C) 2013 Authors. Published by Elsevier B.

    The paper presents a Cloud-based architecture for Ubiquitous and Cloud Manufacturing as a multilayer communicational architecture designated as the Communicational Architecture. It is characterised as (a) rich client interfaces (Rich Internet Application) with sufficient interaction to allow user agility and competence, (b) multimodal, for multiple client device classes support and (c) communicational to allow pragmatics, where human-to-human real interaction is completely supported. The main innovative part of this architecture is sustained by a semiotic framework organised on three main logical levels: (a) device level, which allows the user `to use' pragmatics with the system, (b) application level which results for a set of tools which allows users pragmatics-based interaction and (c) application server level that implements the Pragmatics renderer,a pragmatics supporting engine that supports all pragmatics services. The Pragmatics renderer works as a communication enabler, and consists of a set of integrated collaboration technology that makes the bridge between the user/devices and the `system'. A federated or community cloud is developed using a particular cloud REST ful Application Programming Interface that supports (cloud) services registration, composition and governance (pragmatics services behaves as SaaS in the cloud).The work is supported by the Portuguese National Funding Agency for science, research and technology (FCT), (1) Grant No. UID/CEC/00319/2013, and (2) `Ph.D. Scholarship Grant' reference SFRH/BD/85672/2012.info:eu-repo/semantics/publishedVersio

    Tese Doutoramento Programa Doutoral em Industrial and Systems EngineeringThe aim of this thesis is to explore Architectures of information systems Integration under conditions of dynamic reconfiguration of Virtual Enterprises. The main challenge that we identify and which formed the basis of the research is that information technologies alone cannot support efficiently and effectively the human knowledge and their natural way of interacting. Already from Sausurre (1916) it could be argued that part of knowledge resides in person, and the attempt to try to model it is sufficient for it to be misrepresented. And this is the motto of all this work. Enhance the capabilities of emerging technologies, but in the sense that allow humanto- human interaction, having the information system merely a means to make this possible. Thus we argue that a communicational architecture of information systems integration (where Pragmatics mechanisms are enabled) in virtual enterprises in dynamic reconfiguration scenarios, are better able than the existing transactional architectures. We propose a communicational architecture able to achieve an effective integration of information systems, as well as designing its logical and functional model. We also define the necessary semiotic framework in order to a communicational integration architecture could be efficient and effective. We implemented two prototypes to demonstrate the applicability of the proposed architecture. The demonstration of the research hypothesis was demonstrated with the realization of two experimentations where the ontologies have been unable to resolve disagreements or absences of opinion inherent in people who collaborated. This was overcome with the implementation of mechanisms that allow the co-creation between members of the group that participated in the trial.O objectivo desta tese é explorar Arquitecturas de Integração de Sistemas de Informação em condições de Reconfiguração Dinâmica de Empresas Virtuais. O principal desafio que identificamos e que serviu de base da pesquisa é que as tecnologias de informação por si só não conseguem suportar de forma eficiente e efectiva o conhecimento humano e a sua forma natural de interagir. Já Sausurre (1916) defendia que parte do conhecimento residirá sempre na pessoa, e a tentativa de o tentar modelar é suficiente para que seja deturpado. E esse é o mote de todo este trabalho. Enaltecer as capacidades das tecnologias emergentes mas no sentido de elas permitirem a interacção homem-to-homem, sendo o sistema de informação meramente um meio para que tal seja possível. Argumentamos por isso que uma arquitectura comunicacional de integração de sistemas de informação, onde Pragmatics mechanisms are enabled, em empresas virtuais em cenários de reconfiguração dinâmica, são mais capazes que as actuais arquitecturas transacionais. Propomos para isso uma arquitectura comunicacional capaz de conseguir uma integração efectiva de sistemas de informação, assim como desenhamos o seu modelo lógico e funcional. Definimos ainda o quadro semiótico necessário para que uma arquitectura comunicacional de integração seja eficiente e effectiva. Implementamos dois protótipos capazes de demonstrar a aplicabilidade da arquitectura proposta. A demonstração da hipótese de pesquisa ficou demonstrada com a realização de uma experimentação onde as ontologias se mostraram incapazes de resolver discordâncias ou ausências de opinião inerentes às pessoas que colaboram. Tal foi superado com a aplicação de mecanismos que permitiram a co-criação entre os membros do grupo que realizou a experimentação

    Secure services integration and edge computing for effective beekeeping

    Many of the issues that require resolution are not easy to mitigate just from the technology perspective. The ancestral learned logic of processes, the people traditions, and many other variants define inner contexts that make the adhesion and efficient use of information technologies a delicate process. The enormous geographical dispersion of the beekeeping economic activity, the mostly amateur profile of beekeepers, and the specificity in the traditional way as the activity is managed, compromises the applicability of integrative measures based on ICTE. Efficient and integrated management of a no-professionalized economic activity depends on two basic principles: i) the existence of effective tools capable of managing that activity and its synergies with other related activities, and ii) an infrastructure (technological, procedural, legal) that supports services properly profiled for any actor in that activity. This paper describes the work-in-process sBee - Smart Beekeeping, an applied research project that sought to integrate emerging technologies on the innovative management of critical issues that beekeeping needs to overcome. Electronic devices, Internet-of-things, advanced management algorithms, and innovative visualization services were explored. The global system architecture, its supporting services, and the communication infrastructure are here described. The integration of both internet-of-things and communications services, with the common beekeeping?s management tasks, levered a proposal for improving this activity to become more effective. Furthermore, an advanced technological supporting platform was created and experimented, prepared for further developments, on mitigating emergent challenges that the digitization promotes, namely the security and traceability on food and related agriculture value-chains, as well as on the predictive and intelligent perception of current and future scenarios.911A-2C18-106F | Carlos Jorge Enes Capit?o de AbreuN/

    Monitoring and Information Alignment in Pursuit of an IoT-Enabled Self-Sustainable Interoperability

    To remain competitive with big corporations, small and medium-sized enterprises (SMEs) often need to be more dynamic, adapt to new business situations, react faster, and thereby survive in today‘s global economy. To do so, SMEs normally seek to create consortiums, thus gaining access to new and more opportunities. However, this strategy may also lead to complications. Due to the different sources of enterprise models and semantics, organizations are experiencing difficulties in seamlessly exchanging vital information via electronic means. In their attempt to address this issue, most seek to achieve interoperability by establishing peer-to-peer mappings with different business partners, or by using neutral data standards to regulate communications in optimized networks. Moreover, systems are more and more dynamic, frequently changing to answer new customer‘s requirements, causing new interoperability problems and a reduction of efficiency. Another situation that is constantly changing is the devices used in the enterprises, as the Enterprise Information Systems, devices are used to register internal data, and to be used to monitor several aspects. These devices are constantly changing, following the evolution and growth of the market. So, it is important to monitor these devices and doing a model representation of them. This dissertation proposes a self-sustainable interoperable framework to monitor existing enterprise information systems and their devices, monitor the device/enterprise network for changes and automatically detecting model changes. With this, network harmonization disruptions are detected in a timely way, and possible solutions are suggested to regain the interoperable status, thus enhancing robustness for reaching sustainability of business networks along time

    O objetivo principal deste trabalho passa por estabelecer um sistema ciberfísico orientado para a comunidade no âmbito da produção aberta, recorrendo, então, ao Open Design. Nesse contexto, numa primeira fase, é feita uma revisão bibliográfica sobre estes conceitos, da qual não foram identificados quaisquer trabalhos já realizados que abrangessem tal finalidade. Mesmo assim, e com base no material obtido dessa revisão, juntamente com documentação relativa a trabalhos enquadrados no tema, define-se uma arquitetura, por camadas, que satisfaz o pretendido e enquadra-se na premissa open-source e/ou low-cost. Efetivamente, é elaborado um sistema que permite a qualquer utilizador o acesso livre a um repositório onde se encontra disponível uma vasta gama de produtos, personalizados ou não, os quais são facultados pela própria comunidade. Para que o processamento da informação congruente seja realizável sem limitações, a maior parte do mesmo está alocada na cloud, o qual será auxiliado por um Sistema de MultiAgentes. De seguida, estabelece-se uma ponte de ligação com o mundo físico, por meio de interfaces CPS viabilizadas por dispositivos IoT, os quais conectam e controlam recursos físicos simbólicos à Manufatura Aditiva e Subtrativa, com a finalidade de produzir o produto pretendido. Nesta fase, é possibilitado ao operador e à comunidade acompanhar em tempo real todas as ações e operações realizadas pelos recursos físicos referidos. Juntamente com estes últimos intervenientes, existem igualmente máquinas e processos a cooperar e colaborar simbioticamente para o refinamento do processo de produção, através da análise e recálculo dos dados relacionados com o mesmo. De forma a concretizar esta arquitetura, a implementação da mesma é iniciada, primeiramente a nível físico e, posteriormente, a nível computacional/digital.The main objective of this work is to establish a cyberphysical system oriented to the community within the scope of open production, resorting, then, to Open Design. In this context, in a first phase, a bibliographic review of these concepts is carried out, from which no work that had already been carried out covering this purpose was identified. Even so, and based on the material obtained from this review, together with documentation related to works framed in the theme, an architecture is defined, in layers, which satisfies the intended purpose and falls under the open-source and/or low-cost premise. In fact, a system is created that allows any user free access to a repository where a wide range of products, personalized or not, are available, which are provided by the community itself. For the processing of congruent information to be feasible without limitations, most of it is allocated in the cloud, a process better known as Cloud Computing, which will be supported by a Multi-Agent System. Then, a connection bridge with the physical world is established, through CPS interfaces made possible by IoT devices, which connect and control symbolic physical resources to the Additive and Subtractive Manufacturing, to produce the intended product. At this stage, it is possible for the operator and the community to monitor in real time all actions and operations carried out by the aforementioned resources. Along with these last participants, there are also machines and processes to cooperate and collaborate symbiotically for the refinement of the production process, through the analysis and recalculation of the data related to it. To realize this architecture, its implementation is started, firstly at the physical level and, later, at the computational/digital level

    The e-Government Development Discourse

    research agenda for e-Government. When e-Government was first conceived, it was designed upon basic technologies where the emphasis was only on the simple display of government information for citizens to read. Nowadays, e-Government design comprises many complicated modules such as upload and download consoles, two-way interaction consoles between citizens and government agents, integrated government business processes presenting the whole of government, and it does not depend solely on technology. The complexity of e-Government has now evolved to include political, cultural, economic, social and technical dimensions. Bringing all these difficult aspects together is so complicated that it needs carefully planned strategies informed by local contextual characteristics. Rather than giving formulaic definitions and conceptual standpoints on many aspects of e-Government, as is the case in many e-Government publications, this book will explore the frontiers of global knowledge value chains by discussing current and future dimensions of e-Government. For example, the book discusses the concept of data governance by exploring how actual opening up of government data can be achieved, especially in a developing world context. Further, the book posits that opening government data should be followed by the opening up of government business processes in order to peddle the concept of accountability and responsiveness. Much text on data governance has concentrated on articulating the basic definitions surrounding this concept. Another very important topic explored in this book is regarding how the concept of decolonisation can be extended to e-Government by providing practical examples as to how researchers in the developing world can contribute to the advancement of e-Government as a scientific field of enquiry and guide its implementation, thereof. Decolonisation is advocated for in e-Government research so that there is a balance in the inclusion of the Afrocentric knowledge into e-Government advancement other than over-reliance on the Euro-, Asia- and America-centric knowledge value chains (Mbembe 2015). As e-Government is a very expensive undertaking, the issue of funding has excluded African countries and a majority of the developing world from implementing e-Government. Despite funding being a critical cornerstone of e-Government development, there is a dearth of information on this topic. Therefore, this book provides a chapter which discusses traditional and innovative ways of funding e-Government design and implementation which can go a long way in improving e-Government penetration into the developing world. Further, the book explores how intelligent e-Government applications can be designed, especially in resource-constrained countries. A couple of emerging technology innovations such as fog computing and intelligent information technology are explored within the realm of e-Government design

    Semantic adaptability for the systems interoperability

    In the current global and competitive business context, it is essential that enterprises adapt their knowledge resources in order to smoothly interact and collaborate with others. However, due to the existent multiculturalism of people and enterprises, there are different representation views of business processes or products, even inside a same domain. Consequently, one of the main problems found in the interoperability between enterprise systems and applications is related to semantics. The integration and sharing of enterprises knowledge to build a common lexicon, plays an important role to the semantic adaptability of the information systems. The author proposes a framework to support the development of systems to manage dynamic semantic adaptability resolution. It allows different organisations to participate in a common knowledge base building, letting at the same time maintain their own views of the domain, without compromising the integration between them. Thus, systems are able to be aware of new knowledge, and have the capacity to learn from it and to manage its semantic interoperability in a dynamic and adaptable way. The author endorses the vision that in the near future, the semantic adaptability skills of the enterprise systems will be the booster to enterprises collaboration and the appearance of new business opportunities
