title	Transient Materialization â€“ Robotic Metal Curving
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 423-432
doi	https://doi.org/10.52842/conf.caadria.2020.2.423
summary	This paper introduces the notion of transient materialization to investigate a novel approach of robotic fabrication. Transient materialization explores a new logic of materialization that takes the advantage of differentiated material states to generate form at a particular moment through computation and fabrication technologies. Specifically, this design research explains a unique design and fabrication process, opening up a new method of materializing architectural form that emerges from the interweaving of data, the material capacity (plastic deformation), timing, and machine capacity. Hence, to examine this research direction, this paper conducts an experimental project, Robotic Metal Curving, through hands-on material experiments, as well as the development of algorithms, robot motion, and prototyping machines. This experiment utilizes an induction heating technique in cooperation with a six-axis industrial robotic arm and fabrication equipment used to shape each metal rod into a three-dimensional curve at a transient moment. In addition, the project focuses not only on developing a robotic metal curving system but also apply this technique in large scale by fabricating a wire-frame structure.

title	3D Printed Monolithic Joints - A Mechanically Bistable Joint
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 173-182
doi	https://doi.org/10.52842/conf.caadria.2020.1.173
summary	This paper describes the design and fabrication process of an adaptive joint using 3D printed mono-material bistable mechanisms. The proposed joint deforms when external forces are applied, achieving two stable states. An x-shaped microstructure (simul-SLE) is designed for the connection portion of the bistable structure inside the joint. 3D-Printing experiments is conducted to explore the possibility of various forms of simul-SLE, which realize bistable by a single material. The experiment primarily solved two problems, namely the selection of materials and how to make the rigid 3D printed material acquires properties of flexibility and softness. Finally, practical applications are shown to prove the future of this joint.

doi	https://doi.org/10.52842/conf.caadria.2020.2.273
summary	Elderly living alone have less chance to communicate with their families, so they tend to feel lonely and lack well-being. This study uses gardening activities which is familiar to elderly as the behavioral medium. Make elderly people living alone and their children living in other places through the Internet of Things system to connect space off-site to emotional interaction. Connect children of elderly 'mobile phone apps to HiGame+ potted plants in the home environment of the elderly, so that family members can care and accompany the plants in the homes of the elderly without space restrictions. At the same time, the potted objects will also record the long-term behaviors of the elderly, and will be transformed into the visualization of mood information to interact with children of elderly from other places to break the limit of spatial distance. Give elderly living alone to be emotionally connected and interactive, to increase their well-being.

title	A Method for Load-responsive Inhomogeneity and Anisotropy in 3D Lattice Generation Based on Ellipsoid Packing
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 395-404
doi	https://doi.org/10.52842/conf.caadria.2020.1.395
summary	3D lattice structures are gaining widespread application in multiple design fields. While the number of projects that utilize load-responsive inhomogeneous and anisotropic 3D lattices in design applications increase, accessible and effective algorithmic generation methodologies remain lacking. This paper addresses this gap by introducing a novel computational method for controlled load-responsive inhomogeneity and anisotropy in 3D lattice generation. The presented methods employ a responsive Ellipsoid Packing algorithm informed by the global tensor field of the packing geometry, followed by a Kissing Ellipsoids algorithm to generate the lattice. Load specific anisotropy and inhomogeneity in the ellipsoid packing process is achieved in response to the magnitude and directionality values of the global tensor field and specialized responsive lattices are easily generated. The proposed Ellipsoid Packing workflow is compared to various common lattice generation algorithms. Results show improvement in mechanical performance.

title	Influence of Uncertainties in Envelope and Occupant Parameters on the Reliability of Energy-Based Form Optimization of Office Buildings
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 497-506
doi	https://doi.org/10.52842/conf.caadria.2020.1.497
summary	Building performance optimization is effective in finding optimal designs and improving building energy efficiency, but its reliability can be affected by uncertainties in input parameters. This paper conducts a reliability analysis on energy-based form optimization of office buildings under uncertainties in envelope and occupancy parameters. An optimization process involving Rhinoceros, EnergyPlus and genetic algorithms is first implemented. Then parametric studies of 644 scenarios involving 4 cities in different climates and 3 form variables are conducted. The results indicate that uncertainties in input parameters could lead to major unreliability of optimization results, including reductions up to 13% in energy saving achieved by optimization and descents up to 10% in energy efficiency compared with results before optimization. Moreover, the uncertainty in visual transmittance of windows is the most significant cause for the unreliability, followed by U-value of walls, while the uncertainty in occupant density and occupant schedule has limited influence. The results can help designers understand the uncertainty of which parameters should be controlled and to what extend optimization results can be trusted in various scenarios.

title	A Reconfigurable Joint Based on Extruded Polyhedrons
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 455-464
doi	https://doi.org/10.52842/conf.caadria.2020.1.455
summary	An extruded polyhedron is a reconfigurable geometric shape based on the extrusion of each surface of a polyhedron along the normal direction. This paper introduces an extruded polyhedral joint that uses its own spatial structure to generate multiple states. The component primarily consists of an extruded polyhedron and is equipped with an optional adaptor to adapt to various situations. This research proposes that the formal deformations of a partially extruded polyhedron due to the instability of its own structure give it potential as a reconfigurable joint. To cope with the inevitable deformation of the extruded polyhedron branch cross-section during the overall deformation process, an adaptor - an indispensable component of the entire joint - is utilized at strategic branch locations. In addition, the reconfigurable methods and internal structure of the joints are discussed in detail. Finally, some practical application scenarios for connection components and their advantages in application scenarios are introduced.

title	COVID-19 and the City: Mapping and Critical Analysis of the Virus Propagation in Fortaleza-CE
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 941–953
summary	Social indicators are fundamental tools for measuring social facts, and their use has the potential to facilitate broad access to information. In 2020, the World experienced the beginning of the Coronavirus pandemic, which impacted the socio-spatial reality of cities around the world in several aspects and deepened social inequalities. As part of a coping Covid-19 project by ArqPET, the Somar Platform, this paper presents a mapping process of the spread of Covid-19 in Fortaleza during the four months after its arrival. The mapping, which aims to inform public policies and provides documents that support the demand for adequate housing and sanitary infrastructure in the neglected spaces of the city, relates the spread of the virus to social indicators and uses database technology to optimize its productions.

title	Shape Grammars as a Method to Introduce Computational Thinking in Design - The case of tiles
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 693-702
doi	https://doi.org/10.52842/conf.ecaade.2020.1.693
summary	For architects and other artists, shape grammars, that are part of the computational thinking concept, have been an effective initial tool of transition between the realm of design and the classic computer. The dissemination of computer science and its mindset is only possible when it is supported by adequate pedagogical processes. The presented paper demonstrates an adequate transposition of art solutions (part of tile panels by Athos Bulcao and Maria Keil) into a computational structure where innovative notations are defined in some aspects. To that end, it allows their implementation in the computer through a suitable programming language and uses those same notations to generate other solutions within the same universe of interest and research. Furthermore, an intellectual process is exposed allowing to structure the information, particularly regarding to form, to different frameworks, placing itself as an opportune methodological structure that can guide other similar experiences.

summary	Data sourced by mobile devices has gained importance in urban research techniques. We have conducted two different studies on the usage pattern of a university campus using Wi-Fi connections. We have evaluated this data using anonymization methods more restricted than the Brazilian Data Protection Law. One of our studies is an ongoing work on the campus reopening after the coronavirus crisis. We sought to obtain data that may constitute resources to resilient urban projects on campus. Our results highlight the liability of the more restricted anonymization method and the quality maintenance of the data representation simultaneously.
