    This article approaches the problem of the absence of the technology in the didactics of the Architecture´s Design, in the course of School of Architecture of Lisbon, as the subtitle of the article suggests - the forgotten dimension of the technological perspective.Despite of the course contemplates a relevant technological component, however, does not reflect, much less exponent the creative act of the Project. This is first of all a result of the organization, didactics and contents of the Project classes, and not so much, a lack of knowledge provided to the student in the technological disciplines, which are present in quantity in the curricular structure. The situation, analyzed in this article, is a consequence of a blocking of the Project classes to the technology ones, which do not promote, nor allow, the necessary transdisciplinary articulation and integration between the act of designing and the application of technological knowledge, which is fundamental and intrinsic to the act of thinking and conceiving Architecture.The CAD / CAE / CAM digital tools have not only highlighted the fragility of this didactic process in the didactic context of the current teaching, but, in view of the potential of its operative process, impose the future reformulation of the Project's cognitive practice, integrating the component technology in the Design Methodology of the architect's teaching and praxisN/

    ORAL SESSIONS - Best AbstractsSarcoidosis is a multisystemic disorder of unknown etiology, characterized by the formation of noncaseating granulomas, predominantly in the lungs and lymph nodes. The sarcoidosis association with the ANXA11 rs1049550 SNP has been previously reported in case–control studies. We carried out this meta-analysis in order to collect all the relevant studies to further clarify the association of ANXA11 SNP rs1049550 C/T (R230C variant) polymorphism with Sarcoidosis susceptibility. Relevant published data were retrieved through Medline, PubMed andWeb of Science pertaining to Sarcoidosis and ANXA polymorphisms. Odds ratios (OR) with 95 % confidence intervals (CI) were used to assess the strength of the association. Z test was used to determine the significance of the pooled OR. Statistical heterogeneity was measured using the Q statistic. The effect of heterogeneity was quantified using the I2-statistic. Visual inspection of asymmetry in funnel plots was conducted. Begg’s rank correlation method and Egger weighted regression method were also used to statistically assess the publication bias. Statistical analyses were performed with STATA12.0 software. A total of 6 studies, including 3297 sarcoidosis cases and 3346 healthy controls, were collected in this meta-analysis. For T vs. C, no heterogeneity (Q=4.79, p=0.44, I2=0.0%) was observed among individual estimates, and original data were combined using the fixed-effects model. For the total population, we found that ANXA11 T allele was less common in the Sarcoidosis group than in the control group and we obtained an effect summary OR=0.69, with a 95 % CI=0.64-0.74, and p<0.001, which shows a protective association of SNP rs1049550 T allele to sarcoidosis. Our comprehensive meta-analysis indicated that there is sufficient evidence to demonstrate a conclusive association between the ANXA11 SNP rs1049550 and sarcoidosis susceptibility

    Context-based multi-agent recommender system, supported on IoT, for guiding the occupants of a building in case of a fire

    Get PDF
    The evacuation of buildings in case of fire is a sensitive issue for civil society that also motivates the academic community to develop and study solutions to improve the efficiency of evacuating these spaces. The study of human behavior in fire emergencies has been one of the areas that have deserved the attention of researchers. However, this modeling of human behavior is difficult and complex because it depends on factors that are difficult to know and that vary from country to country. In this paper, a paradigm shift is proposed which, instead of focusing on modeling the behavior of occupants, focuses on conditioning this behavior by providing real-time information on the most efficient evacuation routes. Making this information available to occupants is possible with a solution that takes advantage of the growing use of the IoT (Internet of Things) in buildings to help occupants adapt to the environment. Supported by the IoT, multi-agent recommender systems can help users to adapt to the environment and provide the occupants with the most efficient evacuation routes. This paradigm shift is achieved through a context-based multi-agent recommender system based on contextual data obtained from IoT devices, which recommends the most efficient evacuation routes at any given time. The obtained results suggest that the proposed solution can improve the efficiency of evacuating buildings in the event of a fire; for a scenario with two hundred people following the system recommendations, the time they take to reach a safe place decreases by 17.7%.info:eu-repo/semantics/publishedVersio

    An ontological model for fire evacuation route recommendation in buildings

    Get PDF
    Guiding the occupants of a building to a safe place is an area of research that deserves the attention of researchers. Finding solutions for the problem of guiding the building occupants requires a perfect knowledge of the fire building evacuation domain. The use of ontologies to model the knowledge of a domain allows a common and shared understanding of that domain. This paper presents an ontology that has the purpose to deepen the understanding of that domain and help develop building evacuation solutions and systems capable of guiding the occupants during a building evacuation process. The proposed ontology considers the different variables and actors involved in the fire building evacuation process. The ontology development followed the Methontology methodology, and for implementation, the Protégé tool was used. The ontological model was successfully submitted to a thorough evaluation process and is publicly available on the Web.info:eu-repo/semantics/publishedVersio

    New reactive power compensation strategies for railway infrastructure capacity increasing

    Get PDF
    In AC railway electrification systems, the impact of reactive power flow in the feeding voltage magnitude is one aspect contributing to the quality of supply degradation. Specifically, this issue results in limitations in the infrastructure capacity, either in the maximum number of trains and in maximum train power. In this paper, two reactive power compensation strategies are presented and compared, in terms of the theoretical railway infrastructure capacity. The first strategy considers a static VAR compensator, located in the neutral zone and compensating the substation reactive power, achieving a maximum capacity increase up to 50% without depending on each train active power. The second strategy adapts each train reactive power, achieving also a capacity increase around 50%, only with an increase of the train apparent power below 10%. With a smart metering infrastructure, the implementation of such compensation strategy is viable, satisfying the requirements of real-time knowledge of the railway electrification system state. Specifically, the usage of droop curves to adapt in real time the compensation scheme can bring the operation closer to optimality. Thus, the quality of supply and the infrastructure capacity can be increased with a mobile reactive power compensation scheme, based on a smart metering framework.This research was funded by FCT (Fundação Ciência e Tecnologia) under grant PD/BD/128051/2016.This research is also associated with the Shift2Rail In2Stempo project (grant 777515)

    A flow system using the sample as the carrier with a propulsion device located after the detector is presented. This approach allows the correction of the intrinsic color of the sample, as it provides baseline adjustment for each sample. A confluence situated just after the selection valve allows the sample composition to be adjusted for the colorimetric measurement. The developed methodology was applied to the colorimetric determination of total Fe and Cr (VI) in wastewaters at 0.1–6.0 mg L–1 and 0.03–1.0 mg L–1, respectively. RSDs lower than 3% and a sampling rate of approximately 40 h–1 were obtaine
