Entre las comunidades que habitan los Esteros del Iberá es común encontrar barreras erigidas a partir de elementos naturales extraídos del ambiente, denominadas comúnmente como “cercos naturales”. Estos cumplen la función de delimitar diferentes espacios, mientras que al mismo tiempo se comportan como fuente de recursos naturales y aportan otros beneficios ambientales. En este trabajo se propuso identificar la diversidad de especies vegetales y usos asociados, así como también los diferentes tipos de construcciones de cercos. La metodología utilizada consistió en la aplicación de entrevistas semi-estructuradas, junto a la recolección e identificación de las plantas utilizadas en la construcción de los cercos. Además, se aplicó el índice de Friedman (“fidelity level”- FL) para identificar las plantas preferidas como material de los cercos. Los resultados reconocieron tres tipos de cercos con características que ponen de manifiesto las adaptaciones culturales y al contexto ecológico local al que se adaptaron las comunidades estudiadas en el tiempo. Finalmente se plantea la necesidad de discutir la emergencia de estas construcciones como una “estrategia agroecológica”, así como también el dar continuidad a estas prácticas tradicionales que generan grandes beneficios para el socioecosistema y la conservación biocultural en ambientes tan versátiles como son los humedales del Iberá.

AbstractPrototyping is essential for fuzzy front-end product development. The prototyping process answers questions about critical assumptions and supports design decisions, but it is often unstructured and context-dependent. Previously, we showed how to guide novice designers in early development stages with prototyping milestones. Here, we studied the prototyping success perceived by novice design teams. This was done in two steps: (1) teams were asked to assign each prototype to a milestone, a specific purpose, a fidelity level, and a human-centered design lens, and then evaluate the success using a predefined set of criteria. (2) Teams were interviewed about the success of the prototyping process, this time using self-chosen criteria. Results related to (1) show that teams perceived prototyping activities with respect to desirability and problem validation significantly less successful than prototyping activities towards feasibility and solution validation. Results related to (2) show that teams mostly chose success criteria related to how well prototypes supported communication, decision making, learning, and tangibility. This insight may be used to give priorities to further improvement of methods and guidance in these areas.

Abstract For a particular range of frequencies, an acoustic coupling between the fan and the air intake can modify fan stability regarding flutter. Previous works have shown that characterizing the reflection on the intake opening might be a crucial element to target operating points for which the risk of acoustic driven flutter is high. To do so, three methodologies are compared in this paper: an aeroelastic CFD simulation, an acoustic potential simulation and an analytical model. Each of them has a different fidelity level and computational cost, what makes their usage more beneficial at some step in the design process. It is shown that results of aeroelastic CFD and acoustic potential simulations are in excellent agreement. Fast acoustic simulations are then a good option in the early design process. The analytical model presents an important error mainly on the phase, and should be adapted before usage.

O presente estudo teve como objetivo caracterizar a relação etnobotânica de proprietários rurais do município de Urupema, SC, com recursos florestais. Para isso, foram realizadas entrevistas, em cada uma das 35 propriedades amostradas, sobre as principais fontes de renda e sobre as principais espécies florestais utilizadas. O uso das espécies foi analisado por meio do Nível de Fidelidade (NF) e da Porcentagem de Concordância quanto aos Usos Principais (CUP). As fontes de renda relatadas com maior frequência foram a pecuária, a fruticultura e a aposentadoria. Os recursos florestais são utilizados, principalmente, para fins de alimentação e energético. Todas as espécies citadas apresentaram elevado NF (≥ 97%) e a Araucaria angustifolia (Bertol.) Kuntze é a espécie de maior valor de CUP (97,06%), por ser utilizada por quase a totalidade dos entrevistados (34), sempre para os mesmos fins. Os resultados demonstraram que a maioria dos entrevistados (83%) não obtém renda das florestas naturais, mesmo com quase metade (47%) tendo citado que seria possível sustentar a família por meio da exploração dos recursos florestais nativos. Dentre os recursos florestais explorados, destacou-se a extração de pinhão como fonte de renda.Palavras-chave: Floresta com Araucária; Planalto Catarinense; etnobotânica; produtores rurais. AbstractEthnobotanical connections of rural landowners in the municipality of Urupema, SC, with forest resources. The present research aimed to characterize the ethnobotanical connections of rural landowners in the municipality of Urupema, SC, with their use of forest resource. In order to do that, we conducted interviews, in each of the 35 surveyed properties, focusing the main source of income as well as the main used tree species. The species usages were analyzed by the Fidelity Level (NF) and Percentage of Main Use Concordance (CUP). The most frequent sources of income were livestock, fruit culture and retirement. The forest resources are mainly used as food and energy. All cited species revealed elevated values of NF (≥97%), and the more elevated value of CUP was observed for Araucaria angustifolia (Bertol.) Kuntze (97,06%), as such species had been reported by almost the totality of farmers, always for the same purpose. The results revealed that most of the interviewees (83%) do not get income from natural forests, even with almost half (47%) of them considering that it would be possible to sustain their family by native forest resources exploitation. Among the exploited forest resources, the extraction of pine nuts stood out as income source.Keywords: Araucaria Forest; Planalto Catarinense; forest resource usages; ethnobotany, farmers.

Abstract Multi-fidelity Gaussian process (GP) modeling is a common approach to employ in resource-expensive computationally demanding algorithms such as optimization, calibration and uncertainty quantification where multiple datasets of varying fidelities are encountered. Briefly, in its simplest form, a multi-fidelity GP is trained on two separate sources of datasets each with its own fidelity level, e.g., a software code/simulator for the low-fidelity source and real-world experiments for the high-fidelity source. Adaptive sampling for multi-fidelity Gaussian processes is a challenging task since we not only seek to estimate the next sampling location of the design variable, but also account for the data fidelities. This issue is often addressed by including the cost of the data sources as an another element in the search criterion in conjunction with an uncertainty reduction metric. In this work, we extent the traditional design of experiment framework for multi-fidelity GPs by partitioning the prediction uncertainty based on the fidelity level and the associated cost of execution. In addition, we utilize the concept of a meta-model believer which quantifies the effect of adding an exploratory design point on the GP uncertainty prediction. We demonstrate the framework using academic examples as well as an industrial application of a steady-state thermodynamic operation point of a fluidized bed process.
