Field Work’s Optimization for the Digital Capture of Large University Campuses, Combining Various Techniques of Massive Point Capture

The aim of the study is to obtain fast digitalization of large urban settings. The data of two university campuses in two cities in northern Spain was captured. Challenges were imposed by the lockdown situation caused by the COVID-19 pandemic, which limited mobility and affected the field work for data readings. The idea was to significantly reduce time spent in the field, using a number of resources, and increasing efficiency as economically as possible. The research design is based on the Design Science Research (DSR) concept as a methodological approach to design the solutions generated by means of 3D models. The digitalization of the campuses is based on the analysis, evolution and optimization of LiDAR ALS points clouds captured by government bodies, which are open access and free. Additional TLS capture techniques were used to complement the clouds, with the study of support of UAV-assisted automated photogrammetric techniques. The results show that with points clouds overlapped with 360 images, produced with a combination of resources and techniques, it was possible to reduce the on-site working time by more than two thirds.This research was funded by the Nouvelle-Aquitaine/Euskadi/Navarre Euro-region (AECT). Project co-financed through the second session of the 2019 AECT call for projects

Optimization of polymeric nanofiltration performance for olive-oil-washing wastewater phenols recovery and reclamation

The core of the present work was to model and optimize an environmentally friendly nanofiltration (NF) treatment process for two-phase olive-oil-washing wastewater (OOWW) valorization throughout the concentration and recovery of its phenolic fraction and the obtention of a purified permeate stream. For this objective, a factorial design was used for the optimization of the process. Results were interpreted by means of the response surface methodology. A statistical multifactorial analysis was performed in order to quantify all the potential complex conjugated effects of the input parameters in the NF process. The process was subsequently modelled by means of a second-grade quadratic fitting model equation. Finally, the parametric quality standards that permit to reuse the purified stream for irrigation, recycling or even discharge in-site reuse purposes were checked. To the author's knowledge, no previous work on the optimization and statistical modelling of membrane processes for OOWW purification and valorization can be found up to the present. The optimized parameters for the proposed OOWW purification process – operating pressure of 26.5 bar, tangential velocity 32.7 m s−1, system temperature 35 °C and pH of 3.7 – ensured high and stable membrane flux (106.2 L h−1 m−2). The obtained optimized data are very relevant for the feasible scale-up of the proposed process in the mills, since the NF membrane (TFC polyamide/polysulfone, MWCO 300 Da) was highly efficient at ambient temperature conditions and raw effluent pH. The optimized conditions provided a permeate stream that could be reused for irrigation purposes and a retantate stream concentrated in volume up to 6.5 times, with a total phenolic content of minimum 1315.7 mg/L.Spanish Ministry of Economy and Competitiveness is acknowledged for having funded the project CTM2014-61105-JIN ‘Design and development of an integral process for revalorization and treatment of the effluents from olive oil industry’, as well as the University of Granada

El proceso experimental de composición del color en el Real Club Náutico de San Sebastián, edificio polícromo

[EN] The Real Club Náutico [Royal Nautical Club] of San Sebastián has become an icon of Spanish rationalism and, more specifically, of nautical architecture that is normally associated with the colour, white. However, documentation of the day reveals a polychrome building in harmony with the new architectural forms of expression.The experimental and chromatic test process carried out by Aizpúrua and Labayen on the building has been defined, identifying different phases in the architectural colour composition not described before. A thorough search for photographs has been carried out to determine these phases, classifying them chronologically by means of painstaking dating work. These phases have been characterized by narrowing them down in time, graphically representing them, describing their differences, and seeking the causes that led to these changes. The aim has been to meticulously restore the historical, architectural and symbolic value of the building.[ES] El Real Club Náutico de San Sebastián se ha convertido en un icono del racionalismo español y, en particular, de la arquitectura náutica asociada habitualmente al color blanco. Sin embargo, la documentación de la época desvela un edificio polícromo en consonancia con las nuevas formas de expresión arquitectónica.Se ha definido el proceso experimental y de ensayo cromático llevado a cabo por Aizpúrua y Labayen en el edificio, identificando distintas fases en la composición arquitectónica del color que no han sido previamente descritas. Para su determinación se ha realizado una búsqueda exhaustiva de fotografías, clasificándolas cronológicamente mediante un laborioso trabajo de datación. Se han caracterizado dichas fases acotándolas en el tiempo, representándolas gráficamente, detallando sus diferencias e indagando en las causas que motivaron estos cambios. Todo ello con el objetivo de restituir, en su justa medida, el valor histórico, arquitectónico y simbólico del edificio.Pérez Martínez, JJ.; Senderos Laka, M.; Leon Cascante, I. (2021).

Advanced Techniques for Fast and Accurate Heritage Digitisation in Multiple Case Studies

All elements of heritage are exposed to more or less predictable risks. Even though they are in a good state of conservation with economic support for their repair or maintenance, they can suffer sudden accidents leading to their imminent destruction. It is therefore necessary to safeguard them in all scenarios, regardless of the respective scale or state of conservation. That process must at least be based on complete and accurate 3D digitisation. The evolution of devices, software/hardware and platforms nowadays allows such information to be gathered in a sustainable manner. Various existing resources were tried and compared at several heritage sites of different scales with dissimilar risk and protection, following the guidelines of different ICOMOS (International Council on Monuments and Sites) committees. Each case study addresses the choice of digitisation techniques and the characteristics of the end product obtained. The most suitable modality for each situation is analysed, depending on different factors such as accessibility and risks faced. Although the 3D laser scanner is clearly a very fast and very accurate resource, automated photogrammetry is one of the more accessible and affordable resources; along with the potential of UAVs (unmanned aerial vehicles), this enables the digitisation to be sustainably completed

Mainstreaming graphene in electrochemical energy storage devices: a Delphi-based adaptive priority-setting

Mainstreaming novel materials is essential to overcome crucial limitations of energy storage devices to address societal challenges and decarbonization efforts. However, mainstreaming requires enabling conditions that are influenced by complexities and tensions. Building on the concept of outcome-oriented scaling, this study explores how prioritization of interdependent drivers and barriers influences mainstreaming graphene in electrochemical energy storage devices. We capture the knowledge and perceptions of an expert panel through a Delphi survey combined with in-depth interviews. We find the ongoing prioritization trajectories to fail in setting interdependent drivers and barriers as a vision to achieve impact at scale, in creating opportunities to accelerate mainstreaming, and in addressing key sustainability pressures and reconfiguration barriers. Also, we find widespread consensus that urgent action is required to bend the prioritization trajectories in the right direction to achieve impact at scale. Mainstreaming graphene is likely to challenge, compete and disrupt incumbent systems instead of enabling a smooth transitionThe first author received funding from the Economic Development Agency for La Rioja, under the doctoral fellowship program, grant number: 1168/2018 (Resolución de concesión nº 1168/2018, de la Consejera de Desarrollo Económico e Innovación

Graphic representation, presentation and viewing of the linear landscape. An evolutionary study of the author-presenter-observer relationship

[EN] The linear landscape has historically been rendered in pictures that show a continuous river, a road or train tracks, or by elevations and views depicting a developed space. The problem of presenting such extensive spaces has generated multiple forms of visualisation which comprise a heterogeneous whole. In this article, different modes of presenting the linear landscape are classified according to viewing dynamics and the role of the observer. Changes affecting the roles played by the author, presenter and observer in the various processes described are also examined. The ability to view these spaces through new 3D representation and viewing techniques is addressed, along with the purpose of the author s interpretation in these procedures.[ES] El paisaje lineal ha sido representado a lo largo del tiempo a través de plantas que dibujan un río continuo, una carretera o las vías de un tren, o mediante alzados y vistas que muestran un espacio desarrollado. La dificultad en la presentación de estos extensos espacios ha generado una multiplicidad de formas de visualización que componen un conjunto heterogéneo.En este artículo se clasifican diferentes modos de presentación del paisaje lineal atendiendo al dinamismo en la visualización y al papel del observador. Asimismo, se analizan los cambios producidos en los roles ejercidos por el autor, el presentador y el observador en los diversos procesos descritos. Se abordan las posibilidades de visualización de estos espacios a través de las nuevas técnicas de representación y visualización 3D, así como la función de la interpretación ejercida por el autor en estos procedimientos.Senderos Laka, M.; León Cascante, I.; Pérez Martínez, JJ.
