The Interoperability of Things: Interoperable solutions as an enabler for IoT and Web 3.0
This paper presents an overview of the interoperability concepts along with the challenges for the IoT domain and the upcoming Web 3.0. We identify four levels of interoperability and the relevant solutions for accomplishing vertical and horizontal compatibility between the various layers of a modern IoT ecosystem, referred to as: technological, syntactic, semantic, and organizational interoperability. The goal is to achieve cross-domain interaction and facilitate the proper usage and management of the provided IoT services and applications. An interoperability framework is also proposed where the involved system components can cooperate and offer the seamless operation from the device to the backend framework. This by-design end-to-end interoperation enables the interplay of several complex service composition settings and the management of the system via patterns. The overall proposal is adopted by the EU funded project SEMIoTICS as an enabler towards the IoT and Web 3.0, even when products from different vendors are utilized
High Energy Physics Forum for Computational Excellence: Working Group Reports (I. Applications Software II. Software Libraries and Tools III. Systems)
Computing plays an essential role in all aspects of high energy physics. As
computational technology evolves rapidly in new directions, and data throughput
and volume continue to follow a steep trend-line, it is important for the HEP
community to develop an effective response to a series of expected challenges.
In order to help shape the desired response, the HEP Forum for Computational
Excellence (HEP-FCE) initiated a roadmap planning activity with two key
overlapping drivers -- 1) software effectiveness, and 2) infrastructure and
expertise advancement. The HEP-FCE formed three working groups, 1) Applications
Software, 2) Software Libraries and Tools, and 3) Systems (including systems
software), to provide an overview of the current status of HEP computing and to
present findings and opportunities for the desired HEP computational roadmap.
The final versions of the reports are combined in this document, and are
presented along with introductory material.Comment: 72 page
Perspectives and approaches for the internet of things
Dissertação para obtenção do Grau de Mestre em
Engenharia Electrotécnica e de ComputadoresThis thesis was developed based on a scenario in which a CEO of a certain company asked the author to conduct an exploratory work evaluating the potential opportunities and limitations of this emerging area described as the future of the Internet, the Internet of Things (IoT).
The objective is thus to provide the reader with a wide view of the vital points for the implementation and exploitation of the IoT, a technology that promises to deliver a new and wider range of applications to the society.
In this subject there is a need to gather and organize information produced by several researchers and contributors. Due to the fact of being a new area and researchers work independently of each other, the work is scattered and inconsistencies can be found among different projects and publications. As such, in a first stage some definitions are provided and an attempt to clarify concepts is made.
To support and emphasize the exponential growth of IoT, a brief historical overview is provided to the reader. This overview is based on the new trends and expectations that arise every day through news, potential businesses and also in important tools such as Google Trends. Several examples of applications in the context of the IoT, illustrate the benefits, not only in terms of society, but also for business opportunities, safety, and well-being.
The main areas of interest to achieve the IoT such as: hardware, software, modeling, methods of connection, security and integration are studied in this work, in order to provide some insight into current strong and weak points.
As the Internet of Things become a matter of large interest, various research groups are active in exploring and organizing projects in this area. Some of these projects, namely the ones considered the most important, are also presented in this thesis.
Taking into account the facts surrounding this new technology, it becomes quite important to bring them together, clarifying them and trying to open new perspectives for further studies and improvements.
Finally, in order to allow a practical evaluation of the technology, a prototype is developed around the connection of an intelligent object – a small mobile robot – to the Internet.
A set of conclusions and future work directions are then presented which take into account the findings of the bibliographic analysis as well as the acquired experience with the implementation of the prototype
A Framework for Industry 4.0
The potential of the Industry 4.0 will allow the national industry to develop all kinds of
procedures, especially in terms of competitive differentiation. The prospects and motivations
behind Industry 4.0 are related to the management that is essentially geared towards industrial
internet, to the integrated analysis and use of data, to the digitalization of products and services,
to new disruptive business models and to the cooperation within the value chain. It is through
the integration of Cyber-Physical Systems (CPS), into the maintenance process that it is
possible to carry out a continuous monitoring of industrial machines, as well as to apply
advanced techniques for predictive and proactive maintenance.
The present work is based on the MANTIS project, aiming to construct a specific
platform for the proactive maintenance of industrial machines, targeting particularly the case
of GreenBender ADIRA Steel Sheet. In other words, the aim is to reduce maintenance costs,
increase the efficiency of the process and consequently the profit. Essentially, the MANTIS
project is a multinational research project, where the CISTER Research Unit plays a key role,
particularly in providing the communications infrastructure for one MANTIS Pilot.
The methodology is based on a follow-up study, which is jointly carried with the client,
as well as within the scope of the implementation of the ADIRA Pilot. The macro phases that
are followed in the present work are: 1) detailed analysis of the business needs; 2) preparation
of the architecture specification; 3) implementation/development; 4) tests and validation; 5)
support; 6) stabilization; 7) corrective and evolutionary maintenance; and 8) final project
analysis and corrective measures to be applied in future projects.
The expected results of the development of such project are related to the integration of
the industrial maintenance process, to the continuous monitoring of the machines and to the
application of advanced techniques of preventive and proactive maintenance of industrial
machines, particularly based on techniques and good practices of the Software Engineering area
and on the integration of Cyber-Physical Systems.O potencial desenvolvido pela Indústria 4.0 dotará a indústria nacional de capacidades
para desenvolver todo o tipo de procedimentos, especialmente a nÃvel da diferenciação
competitiva. As perspetivas e as motivações por detrás da Indústria 4.0 estão relacionadas com
uma gestão essencialmente direcionada para a internet industrial, com uma análise integrada e
utilização de dados, com a digitalização de produtos e de serviços, com novos modelos
disruptivos de negócio e com uma cooperação horizontal no âmbito da cadeia de valor. É
através da integração dos sistemas ciber-fÃsicos no processo de manutenção que é possÃvel
proceder a um monitoramento contÃnuo das máquinas, tal como à aplicação de técnicas
avançadas para a manutenção preditiva e pró-ativa das mesmas.
O presente trabalho é baseado no projeto MANTIS, objetivando, portanto, a construção
de uma plataforma especÃfica para a manutenção pró-ativa das máquinas industriais, neste caso
em concreto das prensas, que serão as máquinas industriais analisadas ao longo do presente
trabalho. Dito de um outro modo, objetiva-se, através de uma plataforma em especÃfico, reduzir
todos os custos da sua manutenção, aumentando, portanto, os lucros industriais advindos da
produção. Resumidamente, o projeto MANTIS consiste num projeto de investigação
multinacional, onde a Unidade de Investigação CISTER desenvolve um papel fundamental,
particularmente no fornecimento da infraestrutura de comunicação no Piloto MANTIS.
A metodologia adotada é baseada num estudo de acompanhamento, realizado em
conjunto com o cliente, e no âmbito da implementação do Piloto da ADIRA. As macro fases
que são compreendidas por esta metodologia, e as quais serão seguidas, são: 1) análise
detalhada das necessidades de negócio; 2) preparação da especificação da arquitetura; 3)
implementação/desenvolvimento; 4) testes e validação; 5) suporte; 6) estabilização; 7)
manutenção corretiva e evolutiva; e 8) análise final do projeto e medidas corretivas a aplicar
em projetos futuros.
Os resultados esperados com o desenvolvimento do projeto estão relacionados com a
integração do processo de manutenção industrial, a monitorização contÃnua das máquinas e a
aplicação de técnicas avançadas de manutenção preventiva e pós-ativa das máquinas,
especialmente com base em técnicas e boas práticas da área de Engenharia de Software
A Pilot for Proactive Maintenance in Industry 4.0
13th IEEE International Workshop on Factory Communication Systems (WFCS 2017). 31, May to 2, Jun, 2017. Trondheim, Norway.The reliability and safety of industrial machines
depends on their timely maintenance. The integration of Cyber
Physical Systems within the maintenance process enables both
continuous machine monitoring and the application of advanced
techniques for predictive and proactive machine maintenance.
The building blocks for this revolution – embedded sensors,
efficient preprocessing capabilities, ubiquitous connection to the
internet, cloud-based analysis of the data, prediction algorithms,
and advanced visualization methods – are already in place, but
several hurdles have to be overcome to enable their application in
real scenarios, namely: the integration with existing machines and
existing maintenance processes. Current research and
development efforts are building pilots and prototypes to
demonstrate the feasibility and the merits of advanced
maintenance techniques, and this paper describes a system for the
industrial maintenance of sheet metal working machineryinfo:eu-repo/semantics/publishedVersio

Major requirements for building Smart Homes in Smart Cities based on Internet of Things technologies
The recent boom in the Internet of Things (IoT) will turn Smart Cities and Smart Homes (SH) from hype to reality. SH is the major building block for Smart Cities and have long been a dream for decades, hobbyists in the late 1970s made Home Automation (HA) possible when personal computers started invading home spaces. While SH can share most of the IoT technologies, there are unique characteristics that make SH special. From the result of a recent research survey on SH and IoT technologies, this paper defines the major requirements for building SH. Seven unique requirement recommendations are defined and classified according to the specific quality of the SH building blocks
Quality assessment technique for ubiquitous software and middleware
The new paradigm of computing or information systems is ubiquitous computing systems. The technology-oriented issues of ubiquitous computing systems have made researchers pay much attention to the feasibility study of the technologies rather than building quality assurance indices or guidelines. In this context, measuring quality is the key to developing high-quality ubiquitous computing products. For this reason, various quality models have been defined, adopted and enhanced over the years, for example, the need for one recognised standard quality model (ISO/IEC 9126) is the result of a consensus for a software quality model on three levels: characteristics, sub-characteristics, and metrics. However, it is very much unlikely that this scheme will be directly applicable to ubiquitous computing environments which are considerably different to conventional software, trailing a big concern which is being given to reformulate existing methods, and especially to elaborate new assessment techniques for ubiquitous computing environments. This paper selects appropriate quality characteristics for the ubiquitous computing environment, which can be used as the quality target for both ubiquitous computing product evaluation processes ad development processes. Further, each of the quality characteristics has been expanded with evaluation questions and metrics, in some cases with measures. In addition, this quality model has been applied to the industrial setting of the ubiquitous computing environment. These have revealed that while the approach was sound, there are some parts to be more developed in the future
