Virtual reality in lighting design: Insights from academia and an international survey among professionals
No full textThe potential of virtual reality (VR) in lighting design remains underexplored, despite its growing technological advancements. This study aims to evaluate VR's applicability in lighting design by investigating its benefits, limitations, and adoption among professionals and researchers. A comprehensive literature review highlights VR's capabilities in replicating light distribution and its impact on perception. An international survey conducted from August to December 2023 gathered 57 responses from lighting professionals from 31 countries. Findings reveal that while 83 % of respondents are familiar with VR technologies and recognise the benefit of using VR in practice, its use in lighting design remains limited, with 70 % using VR rarely (46 %) or never (24 %). Key barriers for adoption include a lack of experience, training, time, financial constraints, and hardware limitations. VR is mainly applied for client presentations or conceptual designs, showcasing its potential to enhance client satisfaction despite the basic nature of most environments. This study underscores the need for simple, intuitive, and open-source VR tools to bridge the gap between academic research and professional practice. By aligning VR tools with professional needs, the findings provide a foundation for improving adoption rates and advancing the integration of VR in lighting design. Future research should focus on cost-effectiveness to better evaluate VR's role in improving professionalism and decision-making in the field. The study contributes to filling a critical gap in understanding the practical application of VR in lighting design
Vertikale Entsiegelung
Full text linkDiese Arbeit beschäftigt sich mit einer holistisch geplanten architektonischen Intervention an drei prototypischen Wiener Feuermauern, als Reaktion auf die Herausforderungen der Klimakrise in der historischen Bestandsstadt. Sie thematisiert Fassadenbegrünung, Wasserretention und innovative haustechnischen Konzepte für dicht verbaute Gebiete. Es wird untersucht welche Vielzahl an positiven Effekten ein kleiner aber gesamtheitlich gedachter Eingriff für ein Quartier und die Infrastruktur einer Stadt haben könnte, wenn dieser konsequent entwickelt und umgesetzt wird.Als Ausgangspunkt dient die Hypothese, dass durch die Reduktionen von Brandgefahren die gesetzlichen Sicherheitsanforderungen an Feuermauern gelockert werden könnten. Dies würde neue Rahmenbedingungen schaffen, welche die Umsetzung von Außenbereichen und die Aktivierung vertikaler Brachflächen erleichtern. Daher ist ein Hauptbestandteil dieser Arbeit eine faktenbasierte Argumentation, die zeigt, warum und wie regulatorischen Anpassungen in Bezug auf den Brandschutz möglich wären.In einem nächsten Schritt werden die drei Feuermauern als Reallabore für die jeweils passende Themenstellungen genutzt, um zu überprüfen ob die vertikale Entsiegelung bedeutende ökologische und soziale Beiträge leisten kann. Die Ergebnisse lässt vermuten, dass sie das städtische Mikroklima verbessern, das Kanalsystem entlasten, Kreislaufwirtschaft sichtbar macht, Hitzeinseln reduzieren und den Ausstieg aus Öl und Gas beschleunigen könnten. Aus Feuermauern werden Feiermauern, wenn sie konsequent zu Ende gedacht werden.This work deals with a holistically planned architectural intervention on three prototypical Viennese firewalls in response to the challenges of the climate crisis in the historic city centre. It focuses on façade greening, water retention and innovative building services concepts for densely built-up areas. It examines the multitude of positive effects that a small but holistic intervention could have on a neighbourhood and the infrastructure of a city if it is consistently developed and implemented, based on the hypothesis that the legal safety requirements for firewalls could be relaxed by reducing fire hazards. This would create new framework conditions that would facilitate the realisation of outdoor areas and the activation of vertical brownfield sites. Therefore, a main part of this thesis is a fact-based argumentation that shows why and how regulatory adjustments in terms of fire safety would be possible, and in a next step, the three firewalls are used as real-world laboratories for the respective topics to test whether vertical unsealing can make significant environmental and social contributions. The results suggest that they could improve the urban microclimate, relieve the sewer system, visualise the circular economy, reduce heat islands and accelerate the phase-out of oil and gas. Firewalls become celebration walls if they are thought through to the end
Die nachhaltige Nutzung von Kühlsystemen in öffentlichen Gebäuden
Full text linkKühlsysteme werden in den unterschiedlichsten Bereichen der Wirtschaft eingesetzt. Der primäre Anwendungsbereich ist der Abtransport von Prozesswärme, die im Produktionsablauf anfällt. Das richtige Kühlsystem auszuwählen ist von vielen Faktoren und Einflüssen abhängig. Neben den ausschlaggebenden technischen Parametern, wie Temperatur und Leistung des Kühlsystems, hängt die Wahl des passenden Kühlsystems von den örtlich verfügbaren Ressourcen ab, denn die Errichtung und das Betreiben, sowohl von gewerblichen und industriellen Großgebäuden haben zusätzlichen Anforderungen zu entsprechen. Vor allem müssen diese Kühlsysteme unter dem Blickwinkel einer raschen und preisgünstigen Planung und Errichtung, einer einfachen Wartung, längerfristigen und flexiblen Nutzung, wie auch im Bezug der Energieeffizienzent sprechen. Diese Masterthese setzt sich mit der Thematik der nachhaltigen Nutzung von Kühlsystemen, vor allem im medizinischen Bereich, an öffentlichen Universitäten auseinander. Die Hauptaugenmerke liegen hier auf der umfassenden Beschreibung von Kühlsystemen und ihren Komponenten sowie dem Betrieb und der Vermeidung von Kühlverlusten an Hochsommertagen, da speziell an diesen Tagen große Kapazitäten an Kühlleistungen aufgrund ineffizienter Nutzung, mangelnder technischer Betriebsführung, mangelnder Wartung, Überdimensionierung der Anlagen etc., verloren gehen können
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
