Detailed Mapping of Hydrothermal Vent Fauna: A 3D Reconstruction Approach Based on Video Imagery

Active hydrothermal vent fields are complex, small-scale habitats hosting endemic fauna that changes at scales of centimeters, influenced by topographical variables. In previous studies, it has been shown that the distance to hydrothermal fluids is also a major structuring factor. Imagery analysis based on two dimensional photo stitching revealed insights to the vent field zonation around fluid exits and a basic knowledge of faunal assemblages within hydrothermal vent fields. However, complex three dimensional surfaces could not be adequately replicated in those studies, and the assemblage structure, as well as their relation to abiotic terrain variables, is often only descriptive. In this study we use ROV video imagery of a hydrothermal vent field on the southeastern Indian Ridge in the Indian Ocean. Structure from Motion photogrammetry was applied to build a high resolution 3D reconstruction model of one side of a newly discovered active hydrothermal chimney complex, allowing for the quantification of abundances. Likewise, the reconstruction was used to infer terrain variables at a scale important for megabenthic specimens, which were related to the abundances of the faunal assemblages. Based on the terrain variables, applied random forest model predicted the faunal assemblage distribution with an accuracy of 84.97 %. The most important structuring variables were the distances to diffuse- and black fluid exits, as well as the height of the chimney complex. This novel approach enabled us to classify quantified abundances of megabenthic taxa to distinct faunal assemblages and relate terrain variables to their distribution. The successful prediction of faunal assemblage occurrences further supports the importance of abiotic terrain variables as key structuring factors in hydrothermal systems and offers the possibility to detect suitable areas for Marine Protected areas on larger spatial scales. This technique works for any kind of video imagery, regardless of its initial purpose and can be implemented in marine monitoring and management

Physicochemical and sensory assessments in Spain and United States of PGI-certified Ternera de Navarra vs. Certified Angus Beef

The physicochemical and sensory differences between the PGI-Certified Ternera de Navarra (CTNA) (Spanish origin) and Certified Angus Beef (CAB) (US origin) were assessed in Spain and the USA. To characterize the carcasses, the ribeye areas (REAs), and marbling levels were assessed in both testing places. Twenty striploins per certified beef program were used as study samples. For sensory analysis, the striploins were vacuum packaged and aged for 7 days at 4◦ C and 85% RH in each corresponding laboratory. Thereafter, the samples were half cut and frozen. One of the halves was shipped to the other counterpart-testing place. The fat and moisture percentage content, Warner Bratzler Shear Force (WBSF), and total and soluble collagen were tested for all the samples. The CAB carcasses had smaller REAs (p < 0.0001) and exhibited higher marbling levels (p < 0.0001). The CAB striploins had a higher fat content (p < 0.0001) and required lower WBSF (p < 0.05) than the CTNA samples. Trained panelists rated the CAB samples as juicer (p < 0.001), more tender/less tough (p < 0.0001), and more flavorful (p < 0.0001) than the CTNA counterparts. This study shows that beef from both countries had medium-high tenderness, juiciness, and beef flavor scores and very low off-flavor scores. Relevant differences found between the ratings assigned by the Spanish and the US panelists suggest training differences, or difficulties encountered in using the appropriate terminology for defining each sensory attribute. Furthermore, the lack of product knowledge (i.e., consumption habits) may have been another reason for such differences, despite the blind sensory evaluation.The research was supported by Spanish Ministry of Science and Innovation (Project AGL-2009-13303-CO2-01)

Análisis de la ocupación real en un edificio como factor de ahorro: el caso Adapt4ee

La ocupación real en los edificios es objeto de estudio en diversos campos de investigación entre los que se encuentra la disminución de la demanda energética. En este marco se sitúa el proyecto europeo Adapt4ee - Occupant Aware, Intelligent and Adaptive Enterprises el cual, mediante la integración de los datos de la arquitectura (BIM) y los modelos de proceso de negocio (BPM), ha desarrollado una herramienta de simulación capaz de relacionar el comportamiento energético del edificio con los procesos de negocio, teniendo en cuenta la conducta de los ocupantes. Los actuales softwares de simulación energética consideran la ocupación de los edificios mediante la aplicación de plantillas prediseñadas para diferentes usos de edificios. Sin embargo, el equipo de ingenieros informáticos y arquitectos del proyecto han implementado una serie de perfiles de uso más próximos al comportamiento humano real. Con estos antecedentes, desde el proyecto Adapt4ee se ha analizado y evaluado el comportamiento en tiempo real de los ocupantes en relación con los consumos eléctricos y térmicos, mediante la monitorización de dos edificios en uso. Esta ponencia, por tanto, mostrará los resultados referentes a la ocupación extraídos de simulaciones, del estudio del proceso de negocio y de los datos reales obtenidos
