Ongoing Work

Within the past few years, there has been a steady, substantial growth of interest in “long-term” archiving of digital data. This problem is particularly acute in many branches of engineering design, where cycles of technological obsolescence in supporting tools happen much more rapidly than those of designed products. Capturing and preserving design knowledge through these cycles is a major challenge that has come to be recognized by many government, industry, and research organizations. The ability to do so has important operational, efficiency, and legal ramifications for the manufacturing industry and its customers. This paper describes this problem, presenting examples of both why it must be addressed and why it is a challenge. In particular it relates preservation of engineering data to digital archiving efforts in other domains as well as ongoing work within the engineering research community on design repositories. As is shown, long term archiving of digital design knowledge draws upon both but possesses its own unique issues. Much of this discussion is couched within the language of the ISO Open Archival Information Systems (OAIS) Reference Model, including a mapping from an existing significant design repository into the OAIS model. In this way, it is hoped that this paper will widen the discussion on digital archiving within the community of this conference as well as help connect to research in other areas.

Description Framework

There has been a great deal of interest recently in the problem of long term archiving of digital data. This is especially so in engineering design, where the CAD software tools evolve rapidly but the manufactured products themselves have much longer lifetimes whose support requires archived design data in a usable form. The ISO Open Archival Information Systems (OAIS) Reference Model is a widely used standard for digital archiving, with an essential piece of this model being a file format registry. A file format registry is a system for housing information about file formats that allows for correct interpretation, rendering, storage, and translation of digital files. Currently there exists no file format registry specifically for CAD file formats. This paper explains the purpose of a file format registry for CAD in the greater context of digital archiving, and then presents our approach to creating a CAD file format registry using the Resource Description Framework (RDF) language of the Semantic Web. By creating our file format registry in RDF, we allow archival systems to perform automated reasoning on the stored files. We hope that this paper will increase awareness of this element of engineering design repositories in the research community of this conference.

Long Term Preservation

Long-term-preservation is a much discussed topic and a lot of institutions seem to deal with this question. But most of them are only saving digital data. The authors give a review on considerations and strategies for a longterm preservation of cultural heritage in Austria. The Austrian State Archives already have established an electronic long-term archive for the permanent storage of digital data, called “Digital Archive Austria”. The modular software is based on the Open Archival Information System (OAIS) reference model and follows the concept of a service-oriented architecture with an interface to archival information systems. A web shop with a billing system is part of the service for the access to digital data. For reasons of cost efficiency the Austrian Federal Chancellery has purchased a general license enabling all Austrian provinces, cities, communities and other public authorities to use this archive solution without having to pay license fees all over again.

Long Term Trends

As part of a general inquiry into the economic growth of die United Kingdom, an attempt is being made to estimate long-term trends in output of individual industries over as long a period of time as the data allow. Throughout the eighteenth century wool was the major English manufacturing industry. It is the purpose of this article to consider the evidence of contemporary estimates of the value of the woolen manufacture, with a view to using them as a basis for an assessment of the broad trends in its output over this crucial period of Britain's industrial history.

Scan Data

The inspection of machined objects is one of the most important quality control tasks in the manufacturing industry. Contemporary scanning technologies have provided the impetus for the development of computational inspection methods, where the computer model of the manufactured object is reconstructed from the scan data, and then verified against its digital design model. Scan data, however, are typically very large scale (i.e., many points), unorganized, noisy, and incomplete. Therefore, reconstruction is problematic. To overcome the above problems the reconstruction methods may exploit diverse feature data, that is, diverse information about the properties of the scanned object. Based on this concept, the paper proposes a new method for denoising and reduction in scan data by extended geometric filter. The proposed method is applied directly on the scanned points and is automatic, fast, and straightforward to implement. The paper demonstrates the integration of the proposed method into the framework of the computational inspection process.

Transmission Pipelines

The research described in this paper centers on a composite of thermoplastic materials that can be inserted in a degraded steel pipe to completely restore its strength. Through the use of fabrics consisting of ultra high strength fibers that are co-helically wrapped over a thin walled thermoplastic cylindrical tube that serves as a core, arbitrarily high pressures can be achieved. This paper first outlines the design, manufacturing and installation procedures developed for this unique material to provide a context for the engineering research. Based on this outline, the technological basis that has been developed for assuring the strength and long term durability of this concept during its insertion, and in its very long term service as a liner in energy transmission pipelines, is presented in detail. The research that is described includes burst testing of the material in stand alone pipe form, load/elongation testing of ultra high strength fabrics, and linear and nonlinear elastic and viscoelastic analysis models. This body of work indicates that the concept is fundamentally feasible for restoring a wide range of large diameter natural gas and liquid transmission pipelines to be able to carry arbitrarily high pressures over very long lifetimes. It also indicates that liners can be safely installed in long lengths even in lines with severe bends in a continuous manner. With further research the concept has the potential for eliminating hydro testing and smart pigging during service, and could possibly be installed in some lines that are currently unpiggable.

Everyday Communication

An emerging literature has shown concerns about the impact of the pandemic on the proliferation of digital surveillance. Contributing to these debates, in this paper we demonstrate how the pandemic facilitates digital surveillance in three ways: (1) By shifting everyday communication to digital means it contributes to the generation of extensive amounts of data susceptible to surveillance. (2) It motivates the development of new digital surveillance tools. (3) The pandemic serves as a perfect justification for governments to prolong digital surveillance. We provide empirical anecdotes for these three effects by examining reports by the Global Digital Policy Incubator at Stanford University. Building on our argument, we conclude that we might be on the verge of a dangerous normalization of digital surveillance. Thus, we call on scholars to consider the full effects of public health crises on politics and suggest scrutinizing sources of digital data and the complex relationships between the state, corporate actors, and the sub-contractors behind digital surveillance.

The Way

The paper ascribes to a belief that architecture should be wholly digital – from the scale of the micron and particle to the brick, beam and building, from design to fabrication or construction. This embodies a fundamental and disruptive shift in architecture and design thinking that is unique to the project images included, enabling design to become more inclusive, participatory and open-source. Architecture that is wholly digital requires a radical rethinking of existing design and building practices. Thes projects described in this paper each develops a set of parts in relationship to a specific digital fabrication technology. These parts are defined as open-ended, universal and versatile building blocks, with a digital logic of connectivity. Each physical part has a malefemale connection which is the equivalent of the 0 and 1 in digital data. The design possibilities – or the way that parts can combine and aggregate – can be defined by the geometry and therefore, design agency, of the piece itself. This discrete method advances a theoretical argument about the nature of digital design as needing to be fundamentally discrete, and at the same time responding to ideas coming from open-source, distributed modes methods of production. Furthermore it responds to today’s housing crisis, providing for a more democratic and equitable framework for the production of housing. To think of architecture as wholly digital is to substantially disrupt the way that we think about design, authorship, ownership and process, as well as the building technologies and practices we use in contemporary architectural production.
