Close range mini Uavs photogrammetry for architecture survey

The survey of historical façades contains several bottlenecks, mainly related to the geometrical structure, the decorative framework, the presence of natural or artificial obstacles, the environment limitations. Urban context presents additional restrictions, binding by ground acquisition activity and leading to building data loss. The integration of TLS and close-range photogrammetry allows to go over such stuff, not overcoming the shadows effect due to the ground point of view. In the last year the massive use of UAVs in survey activity has permitted to enlarge survey capabilities, reaching a deeper knowledge in the architecture analysis. In the meanwhile, several behaviour rules have been introduced in different countries, regulating the UAVs use in different field, strongly restricting their application in urban areas. Recently very small and light platforms have been presented, which can partially overcome these rules restrictions, opening to very interesting future scenarios. This article presents the application of one of these very small RPAS (less than 300 g), equipped with a low-cost camera, in a close range photogrammetric survey of an historical building façade in Bologna (Italy). The suggested analysis tries to point out the system accuracy and details acquisition capacity. The final aim of the paper is to validate the application of this new platform in an architectonic survey pipeline, widening the future application of close-range photogrammetry in the architecture acquisition process

The adoption of sustainable practices on personal luxury goods : impact on purchase motivations and intention, emotions, and self-identity

With the growth of the luxury industry in recent years, especially the personal goods segment, and with environmental concerns and sustainability increasingly influencing consumers, it is crucial to understand the role of this industry in the spotlight of sustainability. For this reason, this investigation aims to understand what perceptions, feelings, and purchase intentions current and potential consumers will have about these sustainable luxury products. To do this, based on the literature, information was gathered from individuals by (1) developing a questionnaire to assess consumers’ perceptions and attitudes towards different sustainable strategies, and (2) conduction interviews to deepen the knowledge regarding consumer’s emotions regarding sustainable luxury products. This way, it was possible to assess people's perspectives and understanding of the new sustainable production methods that have been implemented. The results of this investigation reveal that, in general, individuals are considerably concerned about the current state of the environment and that despite their positive purchase intentions for this type of sustainable goods, perceptions about them are not unanimous and deserve further look. Thus, this study provides relevant academic and managerial contributions, as it indicates which sustainable strategies are most familiar to individuals, how they judge and evaluate them, and which of them generates higher purchase intentions, granting a deeper knowledge about the potential consumers in this market segment.Com o crescimento da indústria do luxo nos últimos anos, especialmente no segmento de bens pessoais, e com a sustentabilidade e preocupações ambientais a influenciarem cada vez mais os consumidores, torna-se crucial compreender o papel desta indústria num mundo que caminha para um futuro que se pretende cada vez mais sustentável. Por esta razão, esta investigação visa compreender que perceções, sentimentos e intenções de compra terão os consumidores atuais e potenciais sobre estes produtos de luxo sustentáveis. Para tal, com base na literatura, foram recolhidas informações junto de indivíduos por meio de (1) desenvolvimento de um questionário para avaliar as perceções e atitudes dos consumidores em relação a diferentes estratégias sustentáveis e (2) realização de entrevistas para aprofundar as emoções dos mesmos em relação aos produtos de luxo sustentáveis. Desta forma, foi possível avaliar a perspetiva e compreensão das pessoassobre os novos métodos de produção sustentável que têm vindo a ser implementados. Os resultados desta investigação revelam que, de uma forma geral, os indivíduos estão bastante preocupados com o estado atual do ambiente e que apesar das intenções de compra perante este tipo de bens ser positiva, as perceções sobre os mesmos não são unânimes e merecem ser aprofundadas. Assim, este estudo fornece contributos académicos relevantes para a gestão, visto que indica quais estratégias sustentáveis são mais familiares aos indivíduos, como estes as avaliam e quais geram maiores intenções de compra, proporcionando um conhecimento mais profundo sobre os potenciais consumidores deste segmento de mercado

Analyzing the Applicability of Random Forest-Based Models for the Forecast of Run-of-River Hydropower Generation

ABSTRACT: Analyzing the impact of climate variables into the operational planning processes is essential for the robust implementation of a sustainable power system. This paper deals with the modeling of the run-of-river hydropower production based on climate variables on the European scale. A better understanding of future run-of-river generation patterns has important implications for power systems with increasing shares of solar and wind power. Run-of-river plants are less intermittent than solar or wind but also less dispatchable than dams with storage capacity. However, translating time series of climate data (precipitation and air temperature) into time series of run-of-river-based hydropower generation is not an easy task as it is necessary to capture the complex relationship between the availability of water and the generation of electricity. This task is also more complex when performed for a large interconnected area. In this work, a model is built for several European countries by using machine learning techniques. In particular, we compare the accuracy of models based on the Random Forest algorithm and show that a more accurate model is obtained when a finer spatial resolution of climate data is introduced. We then discuss the practical applicability of a machine learning model for the medium term forecasts and show that some very context specific but influential events are hard to capture.info:eu-repo/semantics/publishedVersio

El conjunto urbano moderno de la Plaza Independencia de Concepción, Chile : 1955-1970

The city of Concepción, has been greatly transformed by the occurrence of several seismic events. During the XX century, modern architecture found, in these events, the agent that allowed its introduction and consolidation as an urban image. Moreover, as posed in this research, one of these events was also responsible for its demise. The 1939 earthquake is related with the production of significant public spaces, and set the basis for a change of the architectonic image of the city through the edification of the first modern style buildings. Also, the 1960 earthquake allowed the consolidation of the modern architecture started by mi 1950¿s. In the other hand, the great earthquake occurred in February 2010, uncovered the process of vanishing of the city modern urban-architectonic image, represented by the intervention strategies applied to urban relevance buildings that were affected by the earthquake. Until the 2010 event, the Plaza Independencia was the place in which three of its four facades were defined by modern buildings. The north-west façade stands out, being emphasized by plate and tower typology, constitute urban character architectural pieces, form Concepción most representative urban facade. Two of the buildings of such facade, the FIUC and El Araucano Hotel buildings, suffered damage that resulted in reconstruction and repair strategies that eliminated the modern features characterizing them. Thus, irreparably and drastically altering the architectonic image of the nor-west facade of the Plaza. The applied intervention strategies, allows us to propose a trend that could mark the future of the modern heritage of the city. A question arises from all the above, why the architectonic image, understood as the system of visual relationships of the oeuvre, of emblematic modern buildings of Concepción, has been erased?. Based on the idea that ¿the expressive organ of architecture is the material with which we balance the structure, we harmonize its proportions and give meaning to the creation process¿, the hypothesis links technical and constructive aspects with the modern form. The most representative modern image would have its origin in the technique as social ideology, that situated it as a modernity icon, based in the extensive use of glass. The technique was not only important from the point of view of the technicality, as it encompassed three scales of indissoluble relationship: the form, the urban form and the technique. Then, research reconstructed, from the perspective of the project, the Plaza Independencia modern urban set (1955-1970), in order to recognize the value of the form and its relationship with the technique, from the visual experience of its study and from the analysis of its technical and formal criteria. Our work allowed to determine which were the contributions of the architectural projects proposals, under the consideration that architectonic image has a direct relationship with the expression of the facade cladding technique, which played a fundamental role to stablish the guidelines that emerge from them. In the light of the performed research on the Plaza Independencia modern urban set, the press of the time, interviews and studies of referents, the FIUC building becomes relevant. Not only from the recognizance of its visual criteria and formal structures derived from the technique that determined its contemporaneity and made it into a city building piece. The major contribution of this research lies in the FIUC building, the discovery of what in the Thesis work we named as the Plan Seccional de 1957 (Sectional Plan of 1957). This Sectional Plan, established the model form of the plate in advance of the plan of Duhart y Goycoolea in 1960, to which traditionally has been attributed the establishment of the plate-tower system for the center of the city.La ciudad de Concepción ha sido escenario de eventos telúricos que han originado en ella grandes transformaciones. Durante el siglo XX, la Arquitectura Moderna encontró en ellos el agente que permitió su introducción y consolidación como imagen urbana y, como se plantea en esta investigación, su desaparición. El terremoto de 1939 se relacionó con la producción de espacios públicos significativos para la ciudad y sentó las bases para un cambio de su imagen arquitectónica, mediante los primeros edificios de corte moderno. El de 1960, permitió la consolidación de la arquitectura moderna iniciada a mediados de los 50. El último, sismo, ocurrido en febrero de 2010, dejó al descubierto el lento proceso de desaparición de la imagen arquitectónico-urbana moderna de la ciudad, al ver las estrategias de intervención en edificios de relevancia urbana que se vieron afectados. Hasta ese entonces, la Plaza Independencia era el lugar donde tres de sus cuatro fachadas estaban definidas por edificios modernos, destacando la norponiente. Aquella, configurada por un conjunto de edificios que, adscritos a la tipología de placa-torre se constituyen en piezas arquitectónicas de carácter urbano, son los que formaron la fachada moderna más representativa de Concepción. Dos de ellos, el edificio FIUC y el del Hotel El Araucano, sufrieron daños que derivaron en estrategias de reconstrucción y reparación que eliminaron los rasgos modernos que los caracterizaban y, con ello, alteraron irreparable y drásticamente la imagen arquitectónica de la fachada nor-poniente de la Plaza. Las estrategias de intervención aplicadas, permiten plantear una tendencia que podría marcar el futuro del patrimonio moderno de la ciudad. De todo lo anterior, surge la pregunta ¿Por qué se ha borrado la imagen arquitectónica, entendida como el sistema de relaciones visuales característico de la obra, de emblemáticos edificios modernos de Concepción? Basándonos en la idea que "el órgano expresivo de la arquitectura es el material con el que equilibramos la estructura, armonizamos sus proporciones y damos significado al proceso de creación", la hipótesis vincula los aspectos técnico-constructivos con la forma moderna. La imagen moderna más representativa tendría su origen en la técnica como ideario social, que la situaba como ícono de la modernidad y estaría basada en el uso extensivo del vidrio. La técnica, no sólo tuvo importancia desde el punto de vista del detalle. Aquella abarcaba tres escalas de relación indisoluble: forma, forma urbana y técnica. La investigación, entonces, reconstruyó, desde la perspectiva del proyecto, el conjunto urbano Moderno de la Plaza Independencia (1955-1970), para reconocer los valores de la forma y su relación con la técnica, desde la experiencia visual de su estudio y del análisis de sus criterios técnicos y formales. Lo anterior permitió determinar cuáles fueron los aportes de aquellos, bajo la consideración que su imagen arquitectónica tiene directa relación con la expresión técnica del cerramiento de fachada. Aquella jugó un rol fundamental para establecer las directrices que de ellos se desprenden. A la luz de la investigación realizada sobre las obras del Conjunto Urbano Moderno de la Plaza Independencia, mediante consulta de prensa de la época, entrevistas y estudio de referentes, cobra relevancia el Edificio FIUC. No sólo desde el reconocimiento de sus criterios visuales y estructuras formales derivadas de la técnica que determinaban su contemporaneidad y lo convertían en una pieza constructora de ciudad. En él radica el mayor aporte de esta investigación, que es el descubrimiento y develación de lo que en la Tesis se determinó llamar como Plan Seccional de 1957, el cual estableció la forma modélica de la placa con anticipación al plan de Duhart y Goycoolea de 1960, al cual tradicionalmente se le ha atribuido la instauración del sistema de placa-torre para el centro de la ciudad

Does Student Engagement Have a Darkside?

Academic misconduct is a growing problem on college campuses. A student’s academic life on campus can take a dark turn if a student does not manage their workload, engagement, or time management well. These variables can overlap if a student is overwhelmed, under-engaged, and busy. A heavy workload can result in a lack of engagement at a student’s institution. Institutions can help students develop strategies that provide a foundation for healthy engagement habits that work against academic dishonesty. Academic success can be affected by students’ time management skills in mitigating the effects of time pressure. Institutions can help students combat a heavy workload with academic campus resources such as writing centers, peer mentors, and advising. These variables can then lead to a student engaging in academic misconduct if they are under-engaged, overly busy, and have poor time management skills
