title Automated Brick Pattern Generator for Robotic Assembly using Machine Learning and Images
source Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 217-226
summary Brickwork is the oldest construction method still in use. Digital technologies, in turn, enabled new methods of representation and automation for bricklaying. While automation explored different approaches, representation was limited to declarative methods, as parametric filling algorithms. Alternatively, this work proposes a framework for automated brickwork using a machine learning model based on image-to-image translation (Conditional Generative Adversarial Networks). The framework consists of creating a dataset, training a model for each bond, and converting the output images into vectorial data for robotic assembly. Criteria such as: reaching wall boundary accuracy, avoidance of unsupported bricks, and brick's position accuracy were individually evaluated for each bond. The results demonstrate that the proposed framework fulfils boundary filling and respects overall bonding structural rules. Size accuracy demonstrated inferior performance for the scale tested. The association of this method with 'self-calibrating' robots could overcome this problem and be easily implemented for on-site.

summary As computers were newly emerging in the field of architectural design, it was claimed that the impact of computers would change the way architects design and present. However, within the course of computer use in design, although the field of architectural practice might have been altered extremely, in architectural education there still seems to be a bond to conventional mind-hand-paper relation. One of the reasons for that bond is the fact that although being r 1000 elated to many technologies, architecture essentially positions itself around an artistic core that is still fed with conventional modes of creation. Architectural education aims at adopting and working on this very core. One of the major contributors in the formation of this core is the presence of author identity. This paper makes a critical approach to computers in terms of expressing author identity in design presentations especially during design education. We believe that the author identity is important in design education in terms of identifying the potential and skills of the student. Especially in design education the final step of design process turns out to be the presentation, unlike architectural practice where the presented design is actually built. Within this conception, two different studies were held in an educational environment with 160 design students and 20 design instructors. The results of both studies pointed at the fact that the digital opportunities that exist for design education should evolve around preserving and underlining the author identity in design presentations.

title Is a Figure-Concept Binary Argumentation Pattern Inherent in Visual Design Reasoning?
source J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary This paper is based on the assumption that because designingis aimed at specifying configurations of entities, designers mustmanipulate forms and shapes and they must resort to visual reasoning todo so. Visual reasoning in designing is seen as the interplay betweenfigural and conceptual reasoning, such that the one supports andcontinues the other in order to arrive at a configuration that is valid interms of all the requirements it is to satisfy. We use protocol analysis toexplore the bond between conceptual and figural reasoning at two levelsof cognitive operation – that of the design move and that of theargument that is its building block. We conclude that the two modes ofreasoning are equi-present in designing; they describe a binary systemcharacterized by high frequency shifts between figure and concept.

title Design Strategies for a 3D Printed Acoustic Mirror

summary Large scale binder-jetting additive manufacturing has been available since almost a decade. While it offers great opportunities for the fabrication of complex ornate forms, so far, the potential of this printing method is not fully explored. Moreover, binder-jetted objects have never been tested for outdoor use and performance, because of the weak bond of the printed parts. This paper presents a design strategy that makes possible the fabrication of large, outdoor installations, with such a fragile material as printed sandstone. The presented process was developed for a full-scale installation of acoustic mirrors that was designed, manufactured and post processed in only a few steps. In the larger picture, this paper discusses how 3D printing can allow for design optimisation and reduction of material, while it proposes post-processing methods that strengthen and seal the printed objects for exterior use.

title The Hand and the Machine: A Hybrid Approach to Complex Construction in a Work of Sir Peter Cook
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 633-642
summary This paper describes and provides a critique of the design and implementation of the “scoops” – a set of bespoke multifunctioning architectural free-form concrete elements that are a highlight of the new Soheil Abedian School of Architecture by the office of Sir Peter Cook and Gavin Robotham (CRAB). The development includes the transfer of analogue design processes into digital 3D modelling, which is then analysed and rationalized via an exchange with consultants and procurement contractors. The complexity of the concrete works necessitated the use of digital fabrication to make their implementation affordable and within time constraints, with said complexity creating a variety of challenges for many aspects of the entire delivery team. The 3D model played a critical role in communicating intent and accuracy at all stages. The use of site-based craftsmanship combined with computer aided design and fabrication overlapped to realize the project.

summary This paper describes and reflects upon a computational de- sign and digital fabrication research project that was developed and implemented over 2014-2015, with subsequent development continu- ing for applications at present. The aim of the research was to develop methods of modelling, analysis, and fabrication that facilitate integra- tive approaches to architectural design and construction. In this con- text, the development of material prototypes, digital simulations, and parametric frameworks were pursued in parallel in order to inform and reform successive iterations throughout the process, leading to a re- fined workflow for engineering, production, and speculation upon fu- ture directions of the work.

summary This paper documents and critically reflects upon the design, development, fabrication, and implementation of three pavilion projects developed during 2013-14. The core investigation of this work is the production of architectural spaces characterized by a quality of enveloping, diffuse, visual and spatial atmospheres. The principal activity of the research is aimed at refining methods for software-based exploration of formal complexities and the subsequent need to control variability and efficiency in fabrication output, using Grasshopper for Rhino to develop customized definitions particular to each specific project scenario. Linking the projects together are issues of scale, resolution of effect, and intent to move from disparate assemblies of structure and skin toward composite, manifold construction techniques that address multiple concerns (gravity, bracing, affect, etc) with a minimum of assembly. A material palette common to the current vernacular of CNC-based projects such as plywood, plastics, and other sheet materials is utilised. This work is invested in extending the possibilities of the architect and architecture as a discipline, extrapolating the workflow from these successive projects to the speculative impact of the work upon emerging possibilities of architectural construction and craft.

summary Scattered solid is a conceptual model consists of a pair of force sources - attractor and repulsor - and particles that possibly bonds together. We hypothesized an abstract or imaginary force field causing particles to move that we can control the tendency of organization by modifying the force fields with a set of parameters such as intensity by distance, time and geometry.

summary This paper aims to describe the theories behind “feeling analysis” techniques applied to digital electronic devices in order to discuss ways to employ them to establish an “affective-emotional model” that could be used to qualify the data visualization processes. The main goal is to analyze and describe “affective-emotional models” that could be used in “dynamic data visualization systems”. In theory, “feeling analysis” techniques, when used to dynamically reconfigure data visualization systems, due to the description of profiles and response patterns, prove to be able to qualify feeding, testing and consulting databases inducting and establishing relations.

title Re-Placing Embodied Interaction: Palestinian Architects Virtual Community
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 381-398
summary Our ongoing project Palestine Architects Platform (PAP) –and PAP VE is a project intended to re-bond Palestinian architects and facilitate communication between them in Virtual Environments “virtual land” using virtual means. We used it as an example to argue that its inherently embedded spatial metaphor could compensate for the physical disconnectedness, and allow interaction on many different levels. Our paper proposes an interactive archiving and networking location where discourse is not only stored but categorised, analysed, retrieved and used to start new topics, or can be used to improve new debates. The focus is on the social values of PAP network and its empowering nature. The design and the structure is not simply a system for online socialisation rather it is a result of thoroughly studying available networks and their principles. It is a result of deep analysis of reality behind this community. We finally propose a set of principles that can secure a real innovative and creative knowledge exchange.

title Making - Gestures: Continuous design through real time Human Machine interaction
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 281-290
summary Design is “something that we do” that is related to our unique human condition as creative individuals, so as “making” is related to how we manifest and impress that uniqueness into our surrounding environment. As designers, the way we impress our ideas into the material world is tightly connected to a ‘continuous creative performance’ and with concepts often missing in digital design and fabrication techniques –yet present in analog processes - such as ambiguity, improvisation and imprecision. In this paper, a model of human-machine interaction is proposed, that seeks to transcend the ‘hylomorphic’ model imperative in today’s digital architectural design practice to a more performative and reciprocal form of computational making. By using body gestures and imbuing fabrication machines with behaviour, the research seeks to embrace the concept of ‘performance and error’ as promoters of creativity and cognition about the things we create, installing human as the bond of the interrelations between designing and making.

summary The production of concrete structure components is often a backbreaking process due to the inconvenient and time-consuming process of producing the formwork. Depending on the geometry, this can be a very time-consuming activity. A trial will be made to solve these problems within the manufacturing process using adapted binder jetting technology. First of all, the research will deal with the behavior of concrete as well as the bond between the cement paste and the aggregate. Various additives and grain sizes will be determined to find an appropriate result. On the other hand, different spray and drop systems will be analyzed to compare the new method and the common binder jetting setup. After fabricating some geometrical shapes manually the study is going to be continued using computer-aided manufacturing.

summary This paper introduces an adaptive robotic spatial aggregation system for the development of an intricate self-supporting glass structure. Rather than using discrete and standardized building elements in the design and fabrication process, this research focuses on utilizing a non-arbitrary shape as an aggregated material for autonomous robotic assembly. More specifically, this paper presents an adaptive robotic fabrication pipeline that measures the size of hollow glass balls (inaccurate materials) as fabrication units to aggregate the entire glass structure. Ultraviolet (UV) curing adhesive is used as the bond between each glass element. Thus, through the live robotic programming as well as various combinations of spherical glass objects and UV curing adhesives/devices, the entire glass structure is self-supported. The project is aimed not only at the development of algorithms and a robotic fabrication system, but also the exploration of the aesthetics of glass materials. In other words, this project investigates a flexible and adaptable framework in response to live sensor data for the design and fabrication of nonstandard spatial structures aggregated out of discrete spherical glass elements, and it further explores glass material aesthetic and perception of architecture.

summary The theory herein offers an alternative to the conventionally accepted concept of an ambiguous electron cloud and postulates a rather well defined structure and motion of electrons around the atomic nucleus that might explain how and why atoms bond with each other to form molecules as they do. If tested and verified, the model could be used to not only predict molecular configurations but also, in reverse procedure, design and engineer artificial atoms and molecules of immense potential, such as of superconductivity.

title Unified Energy-Based Qualitative Representation for Building Analysis
source in J McDonnell and P Lloyd (eds), About: Designing. Analysing Design Meetings, CRC Press, pp. 213-229.
summary Currently, when designers develop a building design project, different representations are used for different building subsystems, such as spatial system, electrical system, lighting system, hydraulic system and HVAC. These representations are mainly used in the final design documentation stage. This book presents a qualitative approach to the development of a unified energy-based representation for building analysis called qualitative Archi Bond Graphs (QABGs). QABGs integrate different representations in the architectural domain into a unified representation. They can be applied in the conceptual, intermediate, and final building design stages. Combining graphical representations and qualitative equations, QABGs are applicable for building simulation and analysis for building dynamics in the space-people system and the building energy systems, and for energy interactions between the space-people system and the building energy systems.
