Evolutionary Computation and Parametric Pattern Generation for Airport Terminal Design
No full textIt is without doubt that airport terminals are some of the most com- plex building types in existence. Their scale, the nature of their func- tions, the strict security measures as well as the function-specific components and building equipment that is present in such build- ings are all factors that increase their level of complexity as a build- ing type. In a real design situation, dealing with the variety of design param- eters that the design of an airport terminal incorporates can be a dif- ficult task to manage and may sometimes become an impediment to the design process. Furthermore, solely because of the enormous amount of possible design solutions that exists even for a relatively small set of design parameters1, the discovery of optimal or near optimal solutions through a traditional design approach is not guar- anteed to happen. Given these assumptions, it has been proposed within the con- text of this project that the design of layouts for airport terminals be addressed by the use of computation-based design methods, specifically Parametric Modelling in combination with evolutionary algorithms, The combination of parametric modelling and evolutionary algorithms has been used consecutively in two scales: First in order to search for optimality regarding the layout of the terminal, and with regard to multiple design goals (accessibility, cost, sustainability, re- tail performance). A Multi Objective Evolutionary Algorithm (MOEA) is used to produce a series of Pareto Optimal solutions, out of which one is selected. Second, a parametric envelope system is applied to the selected layout, and it’s defining parameters are once again optimized, this time with regard to view, sunshading and material usage. Within the context of the project a case study has been performed which focuses on the design of a new terminal at the new Inter- national Airport site in Doha, Qatar. The flexibility of the proposed method allowed for the incorporation of site-specific evaluation cri- teria into the parametric model, allowing for an optimal site-specific solution to be generated, both in terms of layout and of building envelope.Computation & PerformanceBuilding TechnologyArchitectur
Computational Architecture: Focusing on perception and functionality aspects of urban intervention
No full textThis thesis is based on a methodology study in the urban scale. By making use of different examples there are compared the traditional and the computational approach. The goal is to define which method is more appropriate to be used in the urban scale, knowing that the complaxity in this scale is very high. Are the computational methods appropriate to be used in this scale and if it is so, are they able to replace fully the traditional methods used to deal with this scale?Computational Architecture , TU Delft - METU double degree programArchitectureArchitectur
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Real-time measurement of perceptual qualities in conceptual design
No full textImplications of design decisions are hard to oversee for designers. This is the case in particular with respect to decisions, which influence perception related qualities of designs. Such qualities are for example visual openness, visual privacy, and spatial intimacy. They are difficult to measure because of their subjective and soft nature. Measurements of such qualities are important because they are basis for user-oriented, optimal decisions in architectural and interior design. Existing attempts in the architecture domain to assess such qualities systematically are not based on models of visual space perception. Their ability to assess perception aspects of designs is limited. In this paper a novel real-time measurement system for design is presented, which is based on a computational model of visual space perception. This perception model consists of a vision model and a space cognition model. The vision model is based on retrieval of spatial depth data in scattered form. This process is termed random direction distance sampling (RDDS). The space cognition model consists of sample-wise mapping of depth data to perception data, which is space cognition, and exponential averaging, which is a time-series analysis method, for integration of the perception data to perception information, which is the measurement outcome.Architectural Engineering +TechnologyArchitecture and The Built Environmen
