Cellular automata between life science and parametric design: Examples of stochastic models to simulate natural processes and generate morphogenetic artefacts
Full text linkCellular automata are models that deal with both nature and artefacts: they can indeed simulate living beings as well as be employed in the creation of objects. After the introduction of this concept by Stanislaw Ulam and John Von Neumann in the late 1940s, many different kinds of cellular automata have been created and have become part of what Christopher Langton called " artificial life " in 1986. The most complex examples among them are based on stochastic development, thus they share their structural properties with morphogenetic models like the one suggested by Alan Turing (1952). This is the reason why some cellular automata are capable of simulating the development of living beings , but also of cities and artefacts. They are indeed widely used in computer graphics related to parametric design, in order to create performative objects at various scales that can be produced according to the principle of mass customisation. The purpose of this study is to analyse the properties of these models with the help of computer simulations and, as a consequence, to explore some of their different fields of application. As a result, it can be observed that these processes , based on a stochastic geometry, can lead not only to simple biomimicry (regarded as the artificial replication of biological features) but also, in a wider sense, to bioinspiration (a more general relation between nature and artefacts based on shared structural properties)
Artificial Abductive Geometry as a Syntax for Asemic Writings
No full textToday’s developments in morphometry through pattern recognition tools developed for deep learning offer us the elements of a “geometry” obtained a posteriori from the analysis of vast data sets of objects; it is a geometry constructed by “abductive” reasoning, which is very different from the a priori hypothetico-deductive reasoning of geometry tout court. The applications of this abductive morphometric geometry are verifiable retrospectively – in its statistical adaptation to the facts it describes – and prospectively, when used to generate new forms that have a semiotic status comparable to that of “asemic writings”
The drawing and the artefact. Biomorphism in the design of Murano glass objects in the 20th century
No full textBy analysing the relationship between drawing and actual object, it is observed that the design of glass artefacts depends on the features of the material itself, on the processing techniques and their limits. More generally, therefore, we can say that form is the result of forces located inside the matter, as it also happens in the generation of a living organism.
For this reason the discourse on the creation and graphic representation of these objects can be approached from the point of view of biomorphism, a feature that can be found in
similar artefacts on several levels: from the figurativity of the glass animals to the almost abstract shape obtained from the self-organising matter through its intrinsic forces.
It is precisely in the creations with a higher degree of abstraction that we observe the same "biomorphic" feature found in some of the major scientific and artistic studies since the 1950s, although the tradition of blown glass, with its particular processing techniques, is preserved
Environmental Affordances: Some Meetings Between Artificial Aesthetics and Interior Design Theory
Full text linkThe contribution supports the following thesis: the use of semiotic methods of the structural school in applications of Artificial Intelligence allows to deal with aesthetic and historical-critical issues with greater documentation capability. In particular, the contribution concerns an actualisation of the axiology of spatial enhancement built by Jean Marie Floch assuming it as a fundamental semantic framework to construct an interior morphology valid in the various areas of interior design.
Floch’s semiotic analysis allows us to better specify the notion of “environmental affordance” developed in James Gibson’s phenomenology of ecological perception. Following Gibson, the authors indicate an ‘environmental’ specification of the “affordances” and pose the question of their objectification and measurement.
For the purpose of this objectification and measurement of environmental affordances, the contribution advances the hypothesis of using some Artificial Intelligence applications usually employed, nowadays, in the processing of large data sets of digital documents, to achieve creative, critical, historical-archival aims.
In conclusion, the contribution outlines some fundamental conditions of possibility of such an objective measurement by describing some initial characteristics of an artificial system of recognition of morphological categories of interior spaces starting from huge data sets of documents
SCIENTIFIC REFERENCE MODEL – DEFINING STANDARDS, METHODOLOGY AND IMPLEMENTATION OF SERIOUS 3D MODELS IN ARCHAEOLOGY, ART AND ARCHITECTURAL HISTORY
Full text linkIn object-oriented historical research the need to combine hypotheses and textual arguments with the critical analysis based on sources – such as floor plans, sections, perspectives, and photographs – has considerably benefited from the developments in Digital Humanities (Münster, 2022). The use of digital 3D models has overcome many limitations inherent to two-dimensional records. Since the early 1990s hypothetical 3D reconstructions have therefore increasingly become routine research tools and essential means of representation capable of offering new methods of investigation, enabling new insights into the object-related research. In terms of a holistic approach to the analysis and case studies, i.e. the enhanced ability to examine and explore (Favro, 2012) serious challenges remain regarding documentation, interoperability and long-term access to 3D-based research outputs. In this context, numerous initiatives and research projects have emerged with the common objective of systematising and rationalising the various problems identified by scholars. Such projects still tend to remain isolated, lacking a significant impact on the community of potential users. 3D research outputs are not widely applicable, due to the complex prototypes of the software architecture, difficult to apply in a broad sense. Furthermore, the ‘old’ problems still exist, i.e. the traditional approaches - which do not consider a 3D model as a scholarly result, but only an investigative tool - and the reluctance to share these results and the associated procedures. Therefore, an attempt is being made to define the development and evaluation of an applicable methodology for the hypothetical 3D historical reconstruction, based on a shared theoretical approach. The working method presented here reflects many years of engagement with source-based hypothetical 3D reconstruction of no longer extant or unrealised architecture for teaching and research. Our focus is therefore on a low-threshold, application-oriented method of the Scientific Reference Model (SRM) as a documented and published basic model. The structured SRM represents an important working and knowledge state, which clarifies the essential information about the object, its components, its credibility or extent of hypothesis and copyright. Such SRM is made available for further research, edits and refinement, as well as further derivatives (special applications). Thus SRM represents a findable referential result of a scholarly investigation of a material object that physically no longer exists
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
