In this paper an interoperability solution is proposed, aiming to go from (building) construction models to energy simulation. Moreover, the energy simulation results will feed the KPI’s analysis of a designed building. The proposed solution will be used to translate different data formats allowing the communication between different systems in an automated environment. The solution presented in this paper exploits the concept of Plug’n’Interoperate (PnI), that is supported by the principle of self-configuration as to automate, as much as possible, the configuration and participation of systems into a shared interoperability environment. In order to validate this approach two different scenarios were taken into account, translating from a CAD (Computer- Aided Design) model data format to an energy simulation data format.

Industry 4.0 is the new paradigm of the fourth industrial revolution; it embodies a smart industry by applying advanced information and communication systems, and high technology. These advancements evolved and assisted the supply chain to become a more adaptive network creating new opportunities for supply chain competitiveness. Management paradigms as lean and green can develop improvements in the supply chain. The integrative lean and green approach eliminates non-value added activities and at the same time reduces environment impacts and risks throughout the supply chain operations. This study is motivated by the lack of evidence how the lean and green supply chain should evolve to work efficiently in Industry 4.0 environment. The purpose of this study is to investigate whether Industry 4.0 can support the implementation of the lean and green supply chain. Based on literature review, a conceptualization of the relations between Industry 4.0, supply chain management and lean and green paradigms is presented. This paper provides an understanding of how this new industrial revolution incorporated lean and green supply chain paradigms.

Measurements in civil engineering load tests usually require considerable time and complex procedures. Therefore, measurements are usually constrained by the number of sensors resulting in a restricted monitored area. Image processing analysis is an alternative way that enables the measurement of the complete area of interest with a simple and effective setup. In this article photo sequences taken during load displacement tests were captured by a digital camera and processed with image correlation algorithms. Three different image processing algorithms were used with real images taken from tests using specimens of PVC and Plexiglas. The data obtained from the image processing algorithms were also compared with the data from physical sensors. A complete displacement and strain map were obtained. Results show that the accuracy of the measurements obtained by photogrammetry is equivalent to that from the physical sensors but with much less equipment and fewer setup requirements.

This paper presents a detailed study of the energy consumption of the different Java Collection Framework (JFC) implementations. For each method of an implementation in this framework, we present its energy consumption when handling different amounts of data. Knowing the greenest methods for each implementation, we present an energy optimization approach for Java programs: based on calls to JFC methods in the source code of a program, we select the greenest implementation. Finally, we present preliminary results of optimizing a set of Java programs where we obtained 6.2% energy savings.

A importância do papel do Arquiteto-urbanista na caracterização dos conceitos e no planejamento das Smart Cities é um tema com muito por estudar e desenvolver. Este artigo faz uma aproximação a esta questão através de análise crítica com a seguinte abordagem: 1 - é feita uma descrição mais detalhada do porquê deste trabalho de investigação; 2 – apresenta-se uma contextualização da transição dos cenários; 3 - é levantada a problematização e a identificação de alguns motivos do “desenquadramento” da atuação do arquiteto-urbanista na cena; 4 – são discutidos aspectos e elencadas algumas características para “(re)enquadramento” dentro do cenário ideal, 5 – são analisados alguns casos de estudo; 6 - são tecidas conclusões. Este artigo mostra, portanto, o resultado deste estudo comparativo entre panorama atual e desejado, considerando este último como o cenário conceitual. É inicialmente caracterizada a situação atual através de levantamento da crítica especializada, depois é descrita a situação desejada tendo como base a análise de quatro casos de estudo; sendo dois de Smart Cities construídas a partir do zero e dois de cidade existentes que estão sendo transformadas em Smart Cities. Por fim, são identificados elementos que contribuem, na opinião dos autores, para o reassumir do papel do arquiteto-urbanista. Com este trabalho, foi possível, de uma forma sistematizada, estudar e suscitar ações deficitárias na atuação dos arquitetos-urbanistas, como também descortinar potenciais ações que podem induzir e reverter a transformação do cenário atual. Ficou claro que as necessidades intrínsecas ao novo modelo de cidade exigem ainda mais proposições criativas. O delinear das futuras cenas seria então ideal se os arquitetos-urbanistas retomassem posicionamento crítico propositivo e o utilizassem na solução que imagina novas e condizentes maneiras de habitar o espaço. O prelúdio já delineado convida então, os protagonistas na produção do espaço a alforriar-se da inércia, saindo da condição de espectadores e passando a condição de entendedores antecipados do cenário.

A Developmental Coordination Disorder can be identified when children show motor skills either below the expected levels considered adequate to their physical age or the opportunities provided for their learning. This problem affects four to six percent of school-age children, meaning that, from a very early stage of their life, they have several difficulties to adapt to the daily needs. In order to reduce the impact caused by this disorder, a team of therapists from “ – collected a wide range of exercises that allow the stimulus of several motor areas, including both the Gross and Fine Motor Skills. However, the application of this therapeutics is restricted to regular appointments. Since the motor stimulus, in order to be effective, need continuous application, it was found to be necessary to have a tool that in a practical and affordable way, fulfill this need. Therefore, the proposal presented in this article describes the creation of a systematic collection of such exercises in a friendly user manner for the children to be able to exercise elsewhere.

Despite the fact that FRP composites are a reliable structural material with reasonable durability performance, the environment to which the strengthened structure is exposed can make the strengthening system vulnerable. In this study, the effectiveness of Externally Bonded Reinforcement (EBR) systems when external compressive stresses are applied to glass (G) FRP-to-concrete interfaces in several aggressive environments is analysed. The compressive stress imposed on the GFRP-to-concrete interface intends to simulate, for instance, the effect produced by a mechanical anchorage system applied to the EBR system. The design and the region to set those mechanical anchorage systems are not yet well understood and are mostly applied without really knowing how they will behave. This work shows an exhaustive experimental programme based on several double shear tests subjected to salt fog cycles, dry/wet cycles and two distinct temperature cycles: from -10ºC to +30ºC and +7.5ºC to +47.5ºC. The Mohr-Coulomb failure criterion was found to provide a good representation of the performance of the GFRP-to-concrete interface, and changes of cohesion and internal friction angle of those interfaces during the hours of exposure to the aggressive environments are reported.

© 2016 Taylor {&} Francis.A laboratory-based methodology was designed to assess the bioreceptivity of glazed tiles. The experimental set-up consisted of multiple steps: manufacturing of pristine and artificially aged glazed tiles, enrichment of phototrophic microorganisms, inoculation of phototrophs on glazed tiles, incubation under optimal conditions and quantification of biomass. In addition, tile intrinsic properties were assessed to determine which material properties contributed to tile bioreceptivity. Biofilm growth and biomass were appraised by digital image analysis, colorimetry and chlorophyll a analysis. SEM, micro-Raman and micro-particle induced X-ray emission analyses were carried out to investigate the biodeteriorating potential of phototrophic microorganisms on the glazed tiles. This practical and multidisciplinary approach showed that the accelerated colonization conditions allowed different types of tile bioreceptivity to be distinguished and to be related to precise characteristics of the material. Aged tiles showed higher bioreceptivity than pristine tiles due to their higher capillarity and permeability. Moreover, biophysical deterioration caused by chasmoendolithic growth was observed on colonized tile surfaces.
