Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary	The Association for Computer Aided Design in Architecture (ACADIA) was founded on October 17, 1981. The first meeting was held at Carnegie-Mellon University and attended by 24 founding members. When the history of ACADIA is discussed, out of these two dozen founders, three are frequently noted: William Mitchell, Charles Eastman, and Chris Yessios. Mitchell was a pioneer in computer-aided design and smart cities research and is, as Wassim Jabi, ACADIA’s 21st president put it, “one of ACADIA’s most famous founding members.”1 Eastman was not only ACADIA’s first president, but also one of the leading figures in the history of Building Information Modeling (BIM) and is often referred to as “the father of BIM.” Yessios is widely known for his work at Ohio State University and his role in developing Form.Z.

title	The Complexity of Manipulating Hierarchically Defined Sets of Rectangles
source	40 p. : ill. Pittsburgh, PA: Department of Computer Science, CMU., April, 1981. CMU-CS-81-109. includes bibliography
summary	Algorithms that manipulate sets of rectangles are of great practical importance in VLSI design systems and other applications. Although much theoretical work has appeared recently on the complexity of rectangle problems, it has assumed that the inputs are given as a list of rectangles. In this paper the authors study the complexity of rectangle problems when the inputs are given in a hierarchical language that allows the designer to build large designs by replicating small designs. They show that while most of the problems are NP-hard in the general case, there are O(N log N) algorithms that process inputs obeying certain restrictions

title	A Representation Approach to the Tower of Hanoi Problem
source	22 p. : ill. Wollongong: Department of Computing Science, University of Wollongong, August, 1981. includes bibliography
summary	By making the moving direction of each disc explicit in the representation, a bit-string so constructed can be used to drive the Tower of Hanoi algorithm. The behavior of disc moves is further analyzed based on the bit-string representation. It has been shown that the bit-string for moving n discs can be used to generate successively the Gray codes of n bits

title	Matrices of Fibonacci Numbers
source	12 p. Wollongong: Department of Computing Science, University of Wollongong, October, 1981. includes bibliography
summary	The matrices of Fibonacci numbers (called windows) possess some unusual properties which are not shared by normal matrices, such as commutativity under multiplication and +1 for all determinants. The beauty of multiplicative closure lends a hand to the fast computation of generalized order-k Fibonacci numbers in O(k2 log n) time

title	Estimating the Fractal Dimension of Architecture: Using two Measurement Methods implemented in AutoCAD by VBA
doi	https://doi.org/10.52842/conf.ecaade.2012.1.505
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 505-513
summary	The concept of describing and analyzing architecture from a fractal point of view, on which this paper is based, can be traced back to Benoît Mandelbrot (1981) and Carl Bovill (1996) to a considerable extent. In particular, this includes the distinction between scalebound (offering a limited number of characteristic elements) and scaling objects (offering many characteristic elements of scale) made by B. Mandelbrot (1981). In the fi rst place such a differentiation is based upon a visual description. This paper explores the possibility of assistance by two measurement methods, fi rst time introduced to architecture by C. Bovill (1996). While the box-counting method measures or more precisely estimates the box-counting dimension D b of objects (e.g. facades), range analysis examines the rhythm of a design. As CAD programs are familiar to architects during design processes, the author implemented both methods in AutoCAD using the scripting language VBA. First measurements indicate promising results for indicating the distinction between what B. Mandelbrot called scalebound and scaling buildings.

summary	Nowadays as the aim to reduce the environmental impact of buildings becomes more apparent, a new architectural design approach is gaining momentum called sustainable architectural design. Sustainable architectural design process includes some regulations itself, which requires calculations, comparisons and consists of several possible conflicting objectives that need to be considered together. A successful green building design can be performed by the creation of alternative designs generated according to all the sustainability parameters and local regulations in conceptual design stage. As there are conflicting criteria's according to LEED and BREAM sustainable site parameters, local regulations and local climate conditions, an efficient decision support system can be developed by the help of Pareto based non-dominated genetic algorithm (NSGA-II) which is used for several possibly conflicting objectives that need to be considered together. In this paper, a model which aims to produce site layout alternatives according to sustainability criteria for cooperative apartment house complexes, will be mentioned.

summary	Despite increasing interest in the functionality and humanization of architecture, scarcely the occupation of buildings are studied and it lacks methods to represent activities in the spaces. By this reason, it proposes a system such integrates simulation of processes and virtual modeling software, to program the behavior of tri-dimensional characters based on the probabilistic evolution of events, testing this approach in the study of emergency services of hospitals. It describes the procedure developed and reflections about temporal representation, demonstrating that modeling of activities allows to suggest functional and spatial improvements.

summary	¿Can the computer improves the architectural creativity? This question is explored through a Virtual-Reality system developed for the modeling of timber structures, based on parametric elements, constructive programming and immersive visualization on real-time. Making experiences of evaluation with advanced students of architecture, whose use the system in the beginning of projects, compared with other group use not the system. This research faces the possibilities to rationalizate part of the creative process in architecture, broading the role of computer and its contribution to quality of design, and extending the possibilities to teach and share the creation of project. It is argue that major potential in this field is the swiftness, formal variety and spatial living of design, challenging the differences between objective and subjective.

summary	The main objective of this research is to develop a method that can integrate responsive and interactive architecture through the application of soft robotics on a façade. To achieve this objective, a review of the main concepts, adaptive architecture (responsive-interactive) and soft robotics was first carried out. Secondly, recent studies and research that speak of the application of soft robotics in architecture are analyzed. With the knowledge acquired in the analyzes and reference studies, together with the help of programming and computational design tools, a scalable physical prototype was developed that manages to integrate both types of adaptive behaviors (responsive-interactive) in a single hybrid robotic system (soft-rigid), demonstrating the potential of soft robotics in architecture, in this case being applied to be sensitive and act on changes in temperature produced by solar radiation.

title	Geometric Searching In Extended CSG Models : Application to Solid Modeling and Viewing
source	February, 1987. 30 p. : ill
summary	In this paper, the CSG representation scheme is augmented with the 'cartesian product.' The sweep method of generating solids is encompassed by this 'Extended CSG' formalism. The point inclusion problem encountered in the area of geometric searching in computational geometry is discussed in the context to solid models represented by 'extended CSG.' A simple algorithm to solve it that has a time complexity O(n), where n is the number of primitives, is presented. Allowing for preprocessing and extra storage, a second efficient algorithm, having a time complexity O(log n), is developed. The relevance of point inclusion problem in solid modelling techniques is indicated. An extended CSG based solid modeling method is proposed. A solution to the problem of hidden line removal, that uses the faster algorithm for the point inclusion problem, is also presented in the paper

source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 439-448
summary	This paper discusses an approach to adapting trabecular bone structures for the design of complex architectural components exemplified through structural nodes. Based on the paradigm shift in additive fabrication, namely the ability to print structural metals, this paper identifies new methods for architectural and structural design that allow to create porous, intricate architectural components. Those components are designed in analogy to bone structures. The paper presents a metaball-based application, programmed in Processing, which allows creating n-legged nodes using parametric gradient maps. The approach aims at reduction of weight and waste, while exploring the novel aesthetic properties of such bio-constructed networks.

summary	Recently there has been a significant growth on the usage of personal fitness applications running on smart phones or fitness devices. These applications record millions of GPS points generated from the paths of runners. This data can be analyzed to comprehend behavior of runners within a specific location. In this study, using data generated from several sources such as Endomondo and Strava and other complementary data such as climate data, population data etc., we aim to find out the factors affecting running behavior in urban settings. For this purpose, visualizations of running activities are plotted with different variables by using BIG-DID, a software tool we developed as part of this study. Additionally, an evaluation of the tools used or can be used for data analysis and visualizations discussed. Finally, a linear regression model is introduced, which will be further developed in later stages of this study.

summary	Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

title	On the Facial Structure of Scheduling Polyhedra
source	49 p., 6 p. of appendix : ill. Pittsburgh, PA: Design Research Center, Carnegie Mellon Univ., December, 1984. includes bibliography
summary	A well-known job shop scheduling problem can be formulated as follows. Given a graph G with node set N and with directed and undirected arcs, find an orientation of the undirected arcs that minimizes the length of a longest path in G. The author treats the problem as a disjunctive program, without recourse to integer variables, and give a partial characterization of the scheduling polyhedron P(N), i.e., the convex hull of feasible schedules. In particular, he derives all the facets inducing inequalities for the scheduling polyhedron P(K) defined on some clique with node set K, and gives a sufficient condition for such inequalities to also induce facets of P(N). One of our results is that any inequality that induces a facet of P(H) for some HCK, also induces a facet of P(K). Another one is a recursive formula for deriving a facet inducing inequality with p positive coefficients from one with p-1 positive coefficients. The author also addresses the constraint identification problem, and gives a procedure for finding an inequality that cuts off a given solution to a subset of the constraints

summary	The objective of the project is to facilitate the perception of the distance between the technological skills built during the academic journey of the students in Visual Communication Design, and the skills demanded by the labor market. For this research, the Vision in Product (ViP) methodology was used, transferring the results to a possible 2027 scenario. We defined seven professional technological profiles which will help students in their professional insertion, and their adaption to the fast changes in the labor area. Our collaborative and interactive interface was designed to display the data obtained in the survey and the design profiles that will be most in demand in the future. The differential value of our research lies in the possibility of showing the obtained results in a collaborative interface.

title	Virtual Tour Through Modern Architecture in Conception
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 475-477
summary	This paper describes the development of a project that was selected and sponsoured by the Regional Competition FONDART 1998 (Funds for the Development of Arts of the Regional Secretary of Education) that follows the aim of cultural diffusion. Towards the middle of the 30s, the city of Concepción developed an architecture distinctly colonial, neoclassical and eclectic. An earthquake in 1939 abruptly interrupted this scene, destroying the enterity of its most important buildings. The reconstruction of the city followed the manifestoes of Modern Architecture, consolidating the urban importance of buildings such us the Law Courts, the Railway Station and the Regional Government, that emerged as the new architectural and cultural heritage of the city. The project consisted on the modeling of eleven buildings of the modern architectural heritage, and on the generation of 42 virtual tours through the buildings that were finally edited on a 16' video. This video allows the spectator to make a virtual tour through the original modern heritage of the city, nowadays demolished, altered, and sometimes, even forgotten. This project pretends to widen the ways of comprehension of our cultural identity by using computer modelling and animation as a tool for the conservation of the architectural heritage; and creating a record that can be used as a reference and as an instrument of cultural difussion.
