title	3D Scene Representation as a Collection of Images and Fundamental Matrices
source	INRIA Report
summary	The problem we solve in this paper is the following. Suppose we are given N views of a static scene obtained from different viewpoints, perhaps with different cameras. These viewpoints we call reference viewpoints since they are all we know of the scene. We would like to decide if it is possible to predict ano- ther view of the scene taken by a camera from a viewpoint which is arbitrary and a priori di erent from all the reference viewpoints. One method for doing this would be to use these viewpoints to construct a three-dimensional repre- sentation of the scene and reproject this representation on the retinal plane of the virtual camera. In order to achieve this goal, we would have to establish some sort of calibration of our system of cameras, fuse the three-dimensional representations obtained from, say, pairs of cameras thereby obtaining a set of 3-D points, the scene. We would then have to approximate this set of points by surfaces, a segmentation problem which is still mostly unsolved, and then intersect the optical rays from the virtual camera with these sur- faces. This is the most straightforward way of going from a set of images to a new image using the current computer vision paradigm of rst building a three-dimensional representation of the environment from which the rest is derived. We do not claim that there does not exist any simpler way of using the three-dimensional representation than the one we just sketched, but this is just simply not our point. Our point is that it is possible to avoid entirely the explicit three-dimensional reconstruction process: the scene is represented by its images and by some ba- sically linear relations that govern the way points can be put in correspondence between views when they are the images of the same scene-point. These images and their algebraic relations are all we need for predicting a new image. This approach is similar in spirit to the one that has been used in trinocular stereo. Hypotheses of correspondences between two of the images are used to predict features in the third. These predictions can then be checked to validate or inva- lidate the initial correspondence. This approach has proved to be quite e cient and accurate. Related to these ideas are those develo- ped in the photogrammetric community under the name of transfer methods which nd for one or more image points in a given image set, the corresponding points in some new image set.

title	Determining the impact of cad drafting tools on the building delivery process
source	The Int. Journal of Construction IT 2(1), pp.1-8
summary	Computer aided design is intended to change the way design and construction are carried out. at a minimum, this implies savings realized in terms of time spent and improvement of the quality of designs produced. to test this idea, we hypothesized that computer aided drafting and design operations may be instrumental in reducing the number of change orders issued and help control cost overruns by improving the accuracy of construction documents. we compared change orders in projects designed in the conventional media against ones developed with computers. we found that there is evidence supporting our hypothesis. furthermore, in the process of investigating this question, we found that computer applications to improve the management of existing building information (as-built drawings, building system related information, and the like) represent even more critical needs than those that can reduce change orders through more accurate design drawings.

title	GIS: Science or Tool - The Built Environment Perspective
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper attempts to locate GIS in the context of the built environment professions, rather than in the context of computer science, recognizing the integrated but limiting approach of viewingGIS from a strictly computer / spatial science perspective. The paper reviews the conflicts and tensions appearing in the GIS debate seeing them as reflecting the differences between the perceptions and interests of software developers and those of the professions. The "spatial science versus professional tool" dilemma is therefore critically assessed. Science is identified as the dominant paradigm within which GIS development has taken place. This encompasses the emphasis on GIS as spatial science; the interest in particular forms of spatial analysis; a narrow approach to the idea of information; the debate about the appropriate emphasis on the location for GIS in undergraduate education. The interests and activities of the professions cannot be encompassed within the pre-existing science paradigm. The paper identifies the interest the professions have had in broad geographical issues (as distinct from narrow spatial issues). It recognizes the different conventions and procedures used in recording and using geographical information, not all of them objective or scientific. It views the computer, not as a "scientific engine", but as a modern medium for representing and analyzing information. This includes storage and analysis, both internally (algorithmic manipulation) and outside (qualitative manipulation, beyond formal -"computer"- logic). This approach suggests a framework for research of a nature more sympathetic to the needs of the built environment professions in particular and an agenda which would include an examination of: (i) the conventions and procedures used in the professions to collect, store and process information and how these translate to computer technology; (ii) the types of software used and the way procedures may be accommodated by combining and integrating packages; (iii) the dynamism of GIS development (terms such as "dedicated", "mainframe", "PC-based", "distributed", "pseudo-", etc. are identified as indicativeof the need for professions-based approaches to GIS development); (iv) a critique of "information" (modelling of information flows within the professions, may yield valuable insights into the (modelling of information flows within the professions , may yield valuable insights into the similarity of requirements for a variety of "workplace scenarios").

title	Boundaries, Interdependence, and Coordination in ConstructionNetwork Organizations
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Of the profileration of new business paradigms in recent years, one of the primary foci has been building closer relationships between firms in the value adding chain. Lean production, which encompasses J1T, supply-chain management, and TQM/continuous improvement, has provided an important paradigm for reorganization of business practices and is in the process of revolutioni-zing western mass production industries, particularly the automotive industry. While lean production is attractive, it is not appropriate for all industries or production requirements. Lean production works best within a relatively stable production volume and stable range of products. "Mass customization" has proven difficult for accomplished lean producers such as Toyota, and requires a different set of organizational disciplines than those used in lean production. For example, in the lean production paradigm, relationships with suppliers are long-standing and steady, while in a mass customization paradigm, relationships with and between long-term suppliers will vary over time, and new suppliers will enter and leave the organization in a transient fashion. The organization form appropriate to mass customization is the network organization (also known as the virtual corporation in the popular business press), of which construction project organization is an instance, At the project level, we examine construction organization in the context of network organization theory. In particular, we examine boundaries between firms to highlight problems of coordination in a multi-firm environment, and the interdependencies that arise due to coordination needs. We provide a conceptual framework to describe these aspects of construction network organization, and discuss ways that different construction firms are dealing with coordination and boundary problems by rethinking contractual relationships and building closer ties with other firms in the network.

title	Prototipo automatizado para generar alternativas de densificación para la ciudad de maracaibo [An Automated Prototype to Generate Alternatives of Densification for the City of Maracaibo]
source	2da Conferencia Venezolana sobre Aplicación de Computadores en Arquitectura, Maracaibo (Venezuela) december 2001, pp. 174-183
summary	Base upon the model considered by the PDUL (1994), this work proposes and automated prototype that help the architects and urban planners to conceive judgments of value through the manipulation of proposed variables, to elaborate alternatives for different situations needing the increment of the urban density. This document considers two parts of the proposal: The written document, which is the theorical basement of the system; and the prototype, developed to prove the performance of the system. The prototype, on the other hand, is constituted by the "generation of alternatives" and the "help", the theoretical and conceptual support.

title	Architectural Courseware - A Network Based MuItimedia System for Design Education
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 147-150
doi	https://doi.org/10.52842/conf.acadia.1994.147
summary	Architectural Courseware is an interactive system which allows for the creative access of a courserelated multimedia database and the interactive manipulation of that database to enhance design education. This project began as a Teaching Initiative Project supported by the Division of Undergraduate Studies of North Carolina State University, Dr. James Anderson, Dean, and has evolved over two phases. Phase One produced an interactive prototype that explored the requirements and technology of multimedia as a support tool for undergraduate education, specifically for an architecture course in the School of Design, The History of Contemporary Architecture. Phase One was well received by various members of the North Carolina State University: faculty members, the Dean of the School of Design, the directors of the Library and the Computing Center, the Associate Provost for Academic Computing, The Provost, and the Dean of Undergraduate Studies. The Dean of Undergraduate Studies was encouraged by the Associate Provost for University Computing to contribute matching funds for the support of Phase Two of the project. Phase Two focused on a functional implementation of a module of the interactive prototype that could be used by students in the Fall '94 semester to test the effectiveness of the courseware concept.
