TY - CHAP A1 - Östman, L. T1 - Knowledge Elicitation through a Pragmatic Inquiry N2 - This is a paper about knowledge in design and how to elicit knowledge from design processes. The paper is a preparation for an empirical study of interaction in the design process. Reasonings of three authors - Schön, Broadbent and Lundequist - on design processes is presented. They all have a pragmatic perspective in common, and regard the process as an activity without a definite form. Design is seen as an activity of creating models of forms and shapes, by addressing expert knowledge ­ in a dialogic way ­ to problematic situations. Due to the pragmatic approach I find the pragmatist Dewey´s understanding of knowledge and elecitation of knowledge appropiate for studying design processes. According to him it is possible to build up objectified descriptions of experiences, also of such, which are based on experiences of emotional and intuitive nature. There need not be a definite border, which separates tacit knowledge from explicit knowledge - when it comes to the question of the possibility of verbal descriptions. Tacit knowledge is possible to articulate within pragmatic thinking. The conclusion is, that it is possible to study the tacit knowledge of design processes, and get some qualitative insights useful for theory building. A study of design processes can look at three different forms of knowledge. It appears as a pre­cognitive understanding of the design situation, as integrated in the design activity - seeing the situation as something known - and in the process of creating something new.

T1 - Determination of the Temperature of Dissipative Warming and Parameters of Fracture in Elastomers with using of Singular Finite Elements N2 - For modeling of singular fields of stresses and deformations in elasters with a crack is offered to use of three-dimesional a special finite element. Weak compessible of elasters is taken into account on the basis of threefold approximation of fields of displacements, deformations and function of volume change. At intensive cyclic loading of the elastomer constructions with a crack it is necessary to take into account warming and large deformations at the crack top. The stress-deformed state elasters with a crack is determined from the decision of a nonlinear problem by a modified method Newton-Kantorovich. Account stress intensity factors for a rectangular plate with a various arrangement of a through crack is executed. Process of development of a surface crack and dissipative warming in prismatic a element of shift is investigated.

A1 - Poutrain, K. T1 - Models generation : from urban simulation to virtual reality N2 - The aim of researches conducted within gamsau about urban simulation, in particular Remus project, is to allow rapid modeling of large and regular urban zones, for purpose of interactive navigation (like VRML) or for realistic rendering (ray-tracing methods). One of problems to be solved in this context is the multiplicity of data formats : inputs come from different sources, and outputs are for heterogeneous systems of visualization. Typically CSG and boundary representation must be generated, treated and converted during building of models. Furthermore, the generated models can be more or less refined, depending on requests and type of use. This paper describes the general context of data models conversion, problems concerning levels of detail and implementation done in Remus, based on object oriented approach.

T1 - Optimized Models of Modes Choice for Displacement of technical Systems Objects N2 - The effectiveness of working processes accomplished by various technological machines to a large extend depends on working quality of supply, transporting and orientating mechanisms which are very often produced as positional hydro-mechanical systems. The choice of their best type and regimes of work requires construction and analysis of models of their optimum steering which are complicated by nonlinearness, multy-criterialness of problem and also by occasional outbreaks of parameters and moments of steering regime changing. It was developed the common structure of such systems allowing within common scheme to vary the complexity degree of PHMS and the methods of inhibitory efforts supplement. For some systems which are complicated in series (from two-measured linear system to nine-measured non-linear) puzzles of the most fast zero-ambit getting are solved and two-criterial problems are analyzed. (T-min-speed, Z(T)- accuracy). There are suggested the computing procedures of optimum PHMS synthesis. The effectiveness of accepted methods of solving is asserted by the analogy of the results of gradually complicated models investigation and by their good analogy with the natural experiment. It was exposed the sense of heuristic methods of improving of approximately optimum steering, their elaboration on the base of theoretical models. The basic methods of optimum PGMS construction were also nominated.

Zur Bewältigung der umfangreichen und komplizierten Aufgaben des Projektsteuerers wird zunehmend Software angeboten und genutzt. Dabei ist feststellbar, daß von einer integrierten Projektsteuerung unter Berücksichtigung der Kriterien Leistung, Termin und Kosten nicht gesprochen werden kann, weil wesentliche theoretische und praktische Voraussetzungen fehlen. Im Beitrag werden Defizite der praktizierten Vorgehensweise und Lösungsansätze für eine integrierte rechnergestützte Projektsteuerung vorgestellt. Durch geeignete Formen der Projektstrukturierung und eine Kopplung auf dem Mark befindlicher Standardsoftware können geeignete Lösungen gefunden werden. Problempunkte dabei stellen die Schnittstellen zwischen den Anwenderprogrammen die Datenbeschaffung und -verwaltung sowie geeignete Verfahren zur Kostenermittlung und -verfolgung dar.

T1 - Digital Architectural Photogrammetry for Building Registration N2 - For many purposes geometric information about existing buildings is necessary, e.g. planing of conservation or reconstruction. Architectural photogrammetry is a technique to acquire 3D geometric data of buildings for a CAD model from images. In this paper the state of the art in architectural photogrammetry and some developments towards automation are described. The photogrammetric process consists of image acquisition, orientation and restitution. Special attention is put on digital methods, from digital image acquisition to restitution methods, supported by digital image processing. There are a few field of development towards automation, e.g. feature extraction, extraction of edges and lines and the detection of corresponding points. The acquired data may be used in a CAD environment or for visualization in Virtual Reality Models, using digital orthoimages for texture mapping.
