SmartSpaces: aware of users, preferences, behavioursandhabits, in a non-invasive approach

The aim of this work is to take advantage of emerging technologies available in the market that support the so called wearable devices, and the non-invasive particularity of these to, in an autonomous way, adapt the environment to the comfort parameters of each user (e.g. thermal, acoustic, air quality, light, sun exposure). Provide comfort according to the preferences of each individual, is a challenge and an opportunity to create innovative solutions and new paradigms in the context of Intelligent Environments. Currently this challenge has as main difficulties, the people’s mobility, the disparity of habits, schedules and the individual comfort preferences. The same is aggravated when depending on physiological conditions, derived from a large number of factors (tiredness, mood, etc.), user preferences often suffer significant changes, that current systems can not measure.info:eu-repo/semantics/publishedVersio

Manage users and spaces security constraints on a multi-agent system in a adaptive environment system

Nowadays managing user preferences and local actuators specifications is an actual problem on IoT adaptive systems. This paper proposes a multi-agent system to achieve a Smart Environment System, that manages the interaction between persons and physical spaces, where spaces smartly adapt to user preferences in a transparent way. With this work, we also propose a set of security customization to secure actuators and users present in managed spaces, that has been developed using a multi-agent system architecture with different features to achieve a solution to support all proposed objectives.info:eu-repo/semantics/publishedVersio

Landau Gauge Fixing on GPUs and String Tension

We explore the performance of CUDA in performing Landau gauge fixing in Lattice QCD, using the steepest descent method with Fourier acceleration. The code performance was tested in a Tesla C2070, Fermi architecture. We also present a study of the string tension at finite temperature in the confined phase. The string tension is extracted from the color averaged free energy and from the color singlet using Landau gauge fixing.Comment: 7 pages, 4 figures, 1 table.

Landau gauge fixing on the lattice using GPU's

In this work, we consider the GPU implementation of the steepest descent method with Fourier acceleration for Laudau gauge fixing, using CUDA. The performance of the code in a Tesla C2070 GPU is compared with a parallel CPU implementation.Comment: 3 pages, 1 figure, Proceedings of the Xth Quark Confinement and the Hadron Spectrum, 8-12 October 2012, TUM Campus Garching, Munich, German

Behaviour analysis in smart spaces

We are on a new era of interaction between persons and physical spaces. Users want that those spaces smartly adapt to their preferences in a transparent way. This paper describes the process of planning, reasoning and modeling of a Smart Environment with domestic and industrial application, taking advantage of emerging wearable devices on the market (smart watches, fitness trackers, etc.) and newer wireless communication technologies (NFC, BLE, Wi-Fi Direct). Enabling in a noninvasive way for the user, optimize the efficiency, comfort, and safety at the environments. This approach can be applied in home automation, public spaces and also incorporated at industrial level, to help build smart and autonomous factories.info:eu-repo/semantics/publishedVersio

Using ICT to support reflection in pre-service mathematics teacher education

This paper analyses a virtual supervision setting (e-mail and forum) during the practicum in a pre-service secondary school mathematics teacher education program. It is a study of the authors’ own professional practice using a qualitative-interpretative approach and case studies of student teachers. The results show that the setting was significant for pre-service teachers who had a more reflective attitude, but was seen as a burden by the others. The forum enabled fruitful reflections and discussions and e-mail was mostly used for organizational matters. In the future, attention must be paid to the role of the educational supervisor in fostering participation in the forum and use of e-mail.Este artigo analisa um dispositivo de supervisão virtual (e-mail e fórum) durante o estágio num curso de formação inicial de professores de Matemática do ensino secundário. É um estudo dos autores sobre a sua própria prática profissional usando uma abordagem qualitativa e interpretativa e estudos de casos de futuros professores. Os resultados mostram que o dispositivo foi significativo para os futuros professores que tinham uma atitude mais reflexiva mas foi visto como um “peso” pelos outros futuros professores. O fórum permitiu reflexões frutuosas e discussões e o e-mail foi principalmente usado para matérias organizacionais. No futuro, deve ser dada atenção ao papel do supervisor educacional em promover a participação no fórum e o uso do e-mail

Challenges in smart spaces: aware of users, preferences, behaviours and habits

There are new opportunities for research in the field of smart environments that should be explored. The concepts of smart homes and home automation, are currently in growing expansion in the scientific and research point of view, as the market demands for better solutions in this field. Users want that those spaces smartly adapt to their preferences in a transparent way. This paper describes the process of planning, reasoning and modeling of a Smart Environment, using emerging wearable devices on the market (smart watches, fitness trackers, etc.) and newer technologies like NFC, BLE and Wi-Fi Direct.

Smart environment: using a multi-agent system to manage users and spaces preferences conflicts

In this new technological era of the Internet of Things (IoT), people search for comfort and everything that can simplify their daily lives. This paper proposes a smart environment to help achieve this purpose. The problem or challenge, which aims to overcome this, can be defined in general terms as a contribution to creating intelligent environments capable of adapting to the user’s comfort, needs, and preferences in an automatic, transparent, and non-invasive way, whether these environments are for domestic, professional, or public use. We propose the use of a multi-agent system to achieve the management of the user’s preferences, as well as any preference conflicts that may naturally exist. In this way, the space can adapt smartly to the present user’s preferences in a transparent and non-invasive way. This solution also supports the user’s mobility between different spaces and at different times, making it a fully ubiquitous solution, and consequently, an Ambient Intelligence (AmI) solution. We have developed a complete specification of an architecture that supports the proposed solution. The multi-agent system is fully developed, tested, and validated with the presented results.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CeDRI (UIDB/05757/2020 and UIDP/05757/2020) and SusTEC (LA/P/0007/2021)
