title	A General Method for Solving Divide-and-Conquer Recurrences
source	10 p Carnegie Mellon University: December, 1978. includes bibliography.
summary	The complexity of divide-and-conquer algorithms is often described by recurrence relations of the form T(n) = kT(n/c) + f(n). The only method currently available for solving such recurrences consists of solution tables for fixed functions f and varying k and c. In this note the authors describe a unifying method for solving these recurrences that is both general in applicability and easy to apply without the use of large tables

title	General Distortion of an Ensemble of Biparametric Surfaces
source	computer Aided Design. March, 1978. vol. 10: pp. 116-120 : ill. includes bibliography
summary	When the shape of an object has been numerically defined, it is sometimes necessary to distort it to improve either its technical performance or its aesthetic appearance. After briefly recalling the major properties of space curves and surfaces defined by Bernstein polynomials, it is shown how the result can be automatically obtained by distorting an auxiliary triparametric set of references. The principle of an approximate method for high-order curves and surfaces is explained

title	On the structure and use of issue systems in design
source	University of California, Berkeley
summary	The purpose of this dissertation is to explain and justify the concept of issue serving-systems as a new paradigm for descriptive and normative models of design processes. This paradigm is based in general on Horst Rittel's "Argumentative Planning Paradigm" and in particular on Rittel's "Issue-Based Information System" --IBIS-- method. Like IBIS, the issue serving-system concept views design as consisting of the raising and answering of various questions, called issues. The addition of the issue serving-system concept to IBIS is the claim that the serving relationship is the main means for structuring issues into a system for design. That relationship is the one in which an issue A serves an issue B, by which it is meant that the answering of A is useful in deriving the answer to B. Collections of issues structured by this relationship are labelled "issue serving-systems." In the dissertation it is explained that an issue servingsystem has a quasi-hierarchical structure and has as its function the answering of a P!L issue, i.e., an issue of the form, "What should this plan be." Two projects are undertaken in order to demonstrate the normative significance of the issue serving-system concept. The first is to show that the concept forms the basis of a variety of techniques for mechanical (algorithmic) generation of issues and answers. The second is to show how the concept provides criteria for determining which issues should be dealt with and in what order. In particular, it is argued that a topdown breadth-first order of raising issues is best. These conclusions are incorporated into procedures for design, and two applications of these procedures are described. One application involves use of an interactive computer program written by the author. The other involves a non-computerized version of the method.

title	Syntactic structures
source	The Hague : Mouton
summary	Noam Chomsky's first book on syntactic structures is one of the first serious attempts on the part of a linguist to construct within the tradition of scientific theory-construction a comprehensive theory of language which may be understood in the same sense that a chemical, biological theory is understood by experts in those fields. It is not a mere reorganization of the data into a new kind of library catalogue, nor another specualtive philosophy about the nature of man and language, but rather a rigorus explication of our intuitions about our language in terms of an overt axiom system, the theorems derivable from it, explicit results which may be compared with new data and other intuitions, all based plainly on an overt theory of the internal structure of languages; and it may well provide an opportunity for the application of explicity measures of simplicity to decide preference of one form over another form of grammar.

title	An Incompatibility Projector Based on an Interpolant of Gregory
source	computer Graphics and Image Processing. 1978. vol. 8: pp. 294-298. includes bibliography
summary	This paper develops an 'incompatibility Projector' Qm, which is an intrinsically bivariate projector that is not the composition of two univariate projectors. Then it employs Qm to manifest a recent rational interpolant due to Gregory in projector form as a triple Boolean sum. This creates a mold for additional compatibility projectors which yield interpolants to functions that do not meet the ordinary compatibility constraints required for Boolean sum interpolation

title	Analysis of dimensions and tolerances in computer-aided mechanical design
source	Computer Aided Design, vol.10, n.3, may 1978, pp. 161-166
summary	The paper sets forth a theory to explain how dimensions and views combine to specify the shape of a mechanical component. It provides a method to determine whether a component is under, over, or exactly defined by a given dimensioning scheme. Measures for assessing the quality of a scheme are proposed. A solution is offered to a problem of tolerancing: given a toleranced dimensioning scheme, find the resulting tolerances between undimensioned parts of a component.

title	A Cognitive Framework of Collaborative Design Between Architects and Manufacturer-Designers
doi	https://doi.org/10.52842/conf.caadria.2003.855
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 855-870
summary	The widespread application of prefabricated products in building has made prefabrication an indispensable part of building processes. In this context, instead of handling every detail by architects themselves, some parts of architectural design have been transferred to manufacturer-designers. This inevitably brings about problems in the integration of prefabricated products and the specific buildings they serve. As a result, collaboration between architects and manufacturer-designers takes place in building processes in various forms and extents (non-, semi-, and full-collaboration). In this study, we aim to investigate collaborative design process from the cognitive aspect of design generation between architects and manufacturer-designers in terms of project-related products design. By applying the Kernel of Conceptual System theory (Tzonis et al., 1978), we intend to set up two empirical models in terms of design differences' formation in collaborative design process based on a case study with seeking the answers for the following research questions: 1. What kinds of design differences are raised in design processes? 2. Why the design differences are raised in design processes? 3. What implications could be made in developing computational models to facilitate collaborative design between architects and manufacturer-designers?

title	Practices of Distributed Intelligence and Designs for Education
source	Distributed Cognitions, edited by G. Salomon. New York, NY: CambridgeUniversity Press
summary	v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."
