title Towards the development of Smart Buildings: A Lowcost IoT Healthcare Management Proposal in Times of a World Pandemic
source SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 586-593
summary This research addresses the impact that technologies, particularly the Internet of Things, have when facing - directly or indirectly - the current panorama of a pandemic due to COVID-19. First, we review the literature and propose a context that allows for efficient clarification regarding two concerns: where should we insert this project? What are the implications and scope of such a decision? Secondly, we present experiences of implementation of IoT prototypes, which – in context - consider the education of the population of an apartment building, the mitigation and detection of COVID-19 symptoms, and the ability to obtain data from these experiences.

title Do Intelligent Objects Need Programmed Users?
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 52-55
summary Intelligent objects for daily use offer greater advantages than electromechanical products. However, they need a user whose life is more methodical, programmed and predictable. As de number of services offered in such products increase, their restrictions in their flexibility of use arise. Finally, users adapt themselves to habits that these objects suggest (for better) or prescribe (for worse). However, a paradox exists. What is controversial for a standard user: the increasing passivity justified in the eternal pursuit of comfort, for a disabled person means achieving independence and autonomy. In order to accomplish the revolutionary equity that computer science claims, the possibility of being excluded for economic reasons should not exist. If not, it will increase the fracture between coexistent realities in the same territory. For these reasons, assuming the risk of being considered naive and idealist, we believe that in order to build a better future it is necessary to promote policies that guarantee the access to new technologies for people with low economic means. Together with the consciousness users gain -related to product selection-, it would break the premature discouragement that the markets try to impose, resigning us to an unjustified idea of weakness and submission.

summary A research article is presented that seeks to reflect on the relevance and possibility(s) of the incorporation of ontological approaches in the methodological articulation of parametric procedures in architectural design, having as object of study the algorithmic modeling for the digital fabrication of a laminar roof materialized with wood by sub-products from the production of national industries. Such methodological implementation makes possible, as research results, a conceptualization -through a taxonomic structuring supported by relevance- and a systematization by means of a meta-script framed in the universe of possibilities of the ontological approach. The debate problematizes the question of critical appropriation (the convening topic of the present edition of the Sigradi Congress) of methodologies that, arising in realities different from the Ibero-American one, have quickly had an impact in our environment to conclude on the need to emphasize the context parameter in the conceptualization of specific meta-scripts.

title The Synthetic Sublime
source Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 162-175

summary The distinction between the artificial and the natural has been increasingly challenged as a result of advances in genetics, microbiol¬ogy, and robotics. Beginning with the molecular assemblage of organic systems into complex micro-surfaces and structures, and expanding into the realm of the macro landscape, our understanding of the term Synthetic must be revised. What is the relationship between the component (or part) and the whole, when confronted with the Synthetic? Digitally mediated fabrication technologies, combined with a renewed interest in topology and (bio)logical form, serve to challenge our preconceived notions of space and form. This inquiry will attempt to explore the relationship between traditional assemblies produced by hand, and the production of complex forms through digital rapid prototyping. The impact of D'Arcy Thompson's On Growth and Form will be considered both as a historical juncture and a contemporary source of knowledge for the exploration of new assemblages inspired by topology and biology. In particular, the organic micro-surfaces depicted in France Bourély's Hidden Beauty will be explored, in comparison with the mathematical development of organic forms inspired by Periodic Minimal Surfaces. The analysis of emerging forms and assemblages based on the notion of the Synthetic will be compared with the Organic, and considered within the context of twentieth century art and sculpture. An attempt will be made to establish new modes of inquiry for combining digital and physical explorations of space and form, influenced by advances in micro-scale structures, complex surfaces, and the history of organic form in art.

summary The evolution of the architectural surface from a static, fixed geometric assemblage to a responsive, biomimetic aggregate surface will be the topic of this paper. The work exhibited has been developed by the author and his students over the last two years, prompted by an interest in robotics, advanced material assemblies, and biomimetics. The work ranges in scope from digital models and simulations to working prototypes and full-scale habitable constructions. One aspect that serves to unite the emerging body of work may be summarized in the prefix “poly” denoting many, or having more than one state or form. Thus the word Polyform begins to suggest the interplay between biomimesis and adaptive surfaces. A similar term is found in the combination of poly and morph:

doi https://doi.org/10.52842/conf.acadia.2008.272
summary What is the role of Craft, in understanding Bio-Computational Forms & Systems? What is the relation between self-organizing systems & material-component assemblages? ¶ This paper will explore the relationship between material craft, procedure and form, in relation to complex, self-organizing assemblies. A comparison will be made, between (hand) crafted assemblies, guided by physical constraints and procedural methodologies, and digitally mediated fabrication, guided by recursion and algorithmic generative methodologies. ¶ An attempt will be made to connect various scales of making, in terms of module or unit of assembly, both at the micro-scale of biological structures, and the macro-scale of man-made systems. The goal of this essay is to question the relation between physically crafted component assemblies, as a means for exploring adaptive, complex, self-organizing systems, and bio-computational paradigms as a source of adaptive strategies for making.

title An Image Synthesizer
source SIGGRAPH '85 Conference Proceedings. July, 1985. vol. 19 ; no. 3: pp. 287- 296 : ill. includes bibliography
summary The authors introduce the concept of a Pixel Stream Editor. This forms the basis for an interactive synthesizer for designing highly realistic Computer Generated Imagery. The designer works in an interactive Very High Level programming environment which provides a very fast concept/implement/view iteration cycle. Naturalistic visual complexity is built up by composition of non-linear functions, as opposed to the more conventional texture mapping or growth model algorithms. Powerful primitives are included for creating controlled stochastic effects. The concept of 'solid texture' to the field of CGI is introduced. The authors have used this system to create very convincing representations of clouds, fire, water, stars, marble, wood, rock, soap films and crystals. The algorithms created with this paradigm are generally extremely fast, highly realistic, and asynchronously parallelizable at the pixel level

summary With the background of the reflections of the philosopher Vilém Flusser about games on contemporary culture, and the mathematical theory of Constructionism of the educator Seymour Papert, the subject of this work, a doctoral research in progress, relates to the use of a new programming language in the development of design processes in architecture. Intends to examine and explore the similarity of this language with the definition of "open game" by Flusser, whose use seems to favor so-called participatory methods and collaborative work, in which the role of the individual project gives rise to an activity shared by several actors.

title Landscape of the Mind
source Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 71-86
doi https://doi.org/10.52842/conf.acadia.1991.071
summary The focus of this article is the exploration of landscape and the question of representation, more specifically how landscape principles can be represented through computation. It is a quest for essential qualities, through an application of philosophical questioning, and a response to a human perception of reality. Reality, as an invention of the human mind, is often thought of as a set of accepted conventions and constructs. Such a reality has an inherent dependency upon cognition where spatial and temporal principles may be defined within the natural and built environment, and further embraced within a cultural context. However, there also exist rules or relations that are neither invented nor formulated by the participants understanding. In effect these relations may not have been effectively articulated, a result perhaps of unfamiliar cues. Therefore, to the participant, these relations reside in the realm of the unknown or even the mystic. The aesthetic often resides in the realm of the mystic. The discovery of the aesthetic, is often an experience that comes from encountering physical and essential beauty where it has been produced through unconscious relations, perceived, yet transcending human understanding. The aspects of space and time, spatial and temporal properties and relations of things and events, are generally accepted conventions. Yet, the existence of a time order, is often not perceived. An understanding of spatial temporal properties may involve a temporal detachment from convention, allowing the release of previously unknown patterns and relations. Virtual realities are well constructed simulations of our environments, yet they may lack the embedded essential qualities of place. Virtual reality should transcend human perception and traditional modes of understanding, and most importantly our limited notions of the temporal nature of our environment. A desire to reach beyond the limits of perceived time order, may take us beyond existing sets of cultural values, and lead to the realization of new spatial/temporal conventions with the assistance of the computer.

doi https://doi.org/10.52842/conf.acadia.2010.305
summary The instrumental and aesthetic implications of architecture’s engagement with science and technology has a long history, part of which includes the period following the Second World War when the rapid technological advances of the Industrial Revolution merged with a general cultural mindset characterized by themes of progress and futurism. For postwar thinkers like Reyner Banham, this interest in a futurist architecture suggested an approach to design rooted less in architectural precedent than technological extrapolation. While a precedent based approach might be viewed as more disciplinary in nature, technological extrapolation suggests an inclination towards interdisciplinarity. Thus, Banham’s concept of extrapolation encouraged architects to look beyond the limits of their own discipline as a means of discovering new forms of knowledge and expertise. Indeed Banham was engaged in taking stock of the technological advances particular to his time while simultaneously anticipating the implication of these advancements for the future. To this extent, the postwar period and its inherent futurism provides a useful and poignant lens through which to take stock of our own technological climate. Given the equally revolutionary advances in computer technology in the last twenty years, our contemporary moment can be seen as having many parallels with the postwar period, and not unlike the postwar generation of architects and thinkers, contemporary designers are inevitably faced with the challenge of engaging new technological advances and their implications for architecture. In our current age of digital and biological technologies, these advances are both rapid and widespread, and include LED and fiber-optic lighting systems, motion sensing, interface design, solar tracking photovoltaic skins and wind harnessing technologies, magnetic levitation, and robotics. This paper begins with an examination of design work and criticism from the postwar period and proceeds to utilize that examination as an historical framework for addressing issues of contemporary design and 21st Century technological advancement.

summary Advances in large-scale 3D printing technology have opened up explorations on novel non-solid, non-layered 3D printing techniques such as spatial lattices and material draping. These new printing techniques have potential to reduce the wasted material from printing support structures and optimize overall material use. However, due to the inherent material unpredictability of many of these systems, they are often difficult to approximate with digital tools, often requiring simple trial and error to achieve a specific result, with the consequent waste of time and resources. Droop is a work in progress material-informed simulation environment that serves as an iterative design tool for material draping fabrication processes. Droop explores the material potential of thermoplastics through the fabrication process of robotic draping to achieve complex linked catenary forms. This bespoke simulation environment approximates the spatial form of a material draping process and serves as a useful iterative design tool that allows designers to better understand and predict how a 2D pattern translates into a 3D droop form. The simulation also reduces the amount of wasted material produced by trial-and-error material draping processes. In this paper, we present the digital simulation framework, discuss methods for material-informed calibration, and show a set of experiments produced with this tool.

summary The dynamics of COVID-19 spread have been studied from an epidemiological perspective, at city, country, and global scales (Rabajante, 2020, Ma, 2020, and Giuliani et al., 2020), although after two years of the pandemic we know that viruses spread mostly through built environments. This study is part of the Spatiotemporal Modeling of COVID-19 spread in buildings research (Gomez, Hadi, and Kemenova et al., 2020 and 2021), which proposes a multidimensional model that integrates spatial configurations, temporal use of spaces, and virus characteristics into one multidimensional model. This paper presents a specific branch of this model that analyzes the behavioral parameters, such as vaccination, masking, and mRNA booster rates, and compares them to reducing room occupancy. We focused on human behavior, specifically human interactions within six feet. We utilized the multipurpose simulation software, AnyLogic, to quantify individual exposure to the virus, in the high school building by Perkins and Will. The results show how the most effective solution, reducing the occupancy rates or redesigning layouts, being the most impractical one, is as effective as 80% of the population getting a third boost.

summary A reactive planning system for decision support in the context of GIS will be a complex system. The information flow is often great but of varying quality. Resources should be used as knowledge structures to organize the data involved in such systems and generalizations to reduce the data volume and create overviews. This paper discusses what is meant by resources in the context of GIS and planning and how generalizations can be used in a wider perspective than only for cartographic simplification. The project, which is in an early state, has the goal to design the data structures for a decision support system for crisis and emergency management.

title Algorithmic Thinking in Design and Construction - Working with parametric models
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 19-28
summary This paper examines the parametric model in algorithmic design processes, using the outcome of an educational digital design and fabrication course as a case study. In its long history, algorithmic design as a form-finding method, allowed designers to manage complex non-standard associative geometries, suggesting a shift from the digital representation of form, to its systematic representation into a parametric model through code. Rather than a style or a tool, the parametric model is best defined in mathematical terms; in practice it incorporates the organizational logic of the form and the topological associations of its parts, so that a change in its constitutive parameters will invoke a concerted update of the entire model, and, iteratively, formal and structural variations. In a series of design experiments that took place at the School of Architecture of the Technical University of Crete in the spring of 2015, we used parametric models represented into visual code, from the initial conceptual stage to fabrication. From the experience and outcome of this course, we deduced that, compared to other digital formation methods, parametric models allow the designer to constantly interact with the model through the code, producing discreet variations without losing control of the design intentions, by “searching” into a wide range (albeit finite) of virtual results. This suggested a shift in culturally embedded patterns of modernist design thinking.
