Graphic arts requirements for electronic image management systems for the library and corporate information center

The value of legacy documents, important documents that exist only in printed form, is increased when those documents are transformed by an Electronic Image Management (EIM) System into digital form. The image quality observed from many of these systems is much poorer than that which is typical in the Graphic Arts field. This research has sought to understand whether the poor quality was due to the past constraints of slow computing power, high storage costs, and narrow network bandwidths. Users of EIM systems in Libraries and Corporate Information Centers were interviewed to assess their fundamental quality requirements relative to competing requirements for cost, turnaround time and speed. The process tool, Quality Function Deployment (QFD), was used to gather and process user requirements. QFD was chosen because of it\u27s methodical structure for the interview process and subsequent analysis. The resulting requirements were organized into a QFD House of Quality , arraying customer requirements against technical responses. Subsequent analysis of the House of Quality and transcripts of the customer interviews suggests that requirements for high speed and low cost, predominate over Graphic Arts quality for most users. The focus on speed and cost was most obvious for those applying EIM to commercial purposes in Corporate Information Centers. While Library users had a shared interest in speed and cost, they have a specialty application of EIM, preservation and conservation. In this application, EIM is used to preserve and save printed documents that are deteriorating. For this specialty application, quality is paramount. While cost and speed are still important, they cannot be sacrificed for quality or speed

Reverse engineering of printed circuit boards: A conceptual idea

One of the backbones in electronic manufacturing industry is the printed circuit board (PCB).The recent rapid growth in electronics devices, results escalating in the production number of the PCBs.For electronic equipment and appliances which are PCB based, new generations of PCB's are produced to suit the requirements of new products.This development can lead to waste and inefficiency when perfectly serviceable electronic components and appliances have to be scrapped because of the unavailability of spare PCB's from the Original Equipment Manufacturer (OEM) or are already obsolete.This paper proposed a novel framework for reverse engineering of obsolete single layer PCB.Equivalent PCB's which can be used as spares will be reproduced utilizing this new framework.This framework involves several steps, such as Data Acquisition, Image Processing, CAD Editing, PCB Fabrication and Circuitry testing and Analysis.Each stage of the framework and the functionality evaluation of the reproduced PCB will be discussed in detail in following sections

Using geographical information systems for management of back-pain data

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2002 MCB UP LtdIn the medical world, statistical visualisation has largely been confined to the realm of relatively simple geographical applications. This remains the case, even though hospitals have been collecting spatial data relating to patients. In particular, hospitals have a wealth of back pain information, which includes pain drawings, usually detailing the spatial distribution and type of pain suffered by back-pain patients. Proposes several technological solutions, which permit data within back-pain datasets to be digitally linked to the pain drawings in order to provide methods of computer-based data management and analysis. In particular, proposes the use of geographical information systems (GIS), up till now a tool used mainly in the geographic and cartographic domains, to provide novel and powerful ways of visualising and managing back-pain data. A comparative evaluation of the proposed solutions shows that, although adding complexity and cost, the GIS-based solution is the one most appropriate for visualisation and analysis of back-pain datasets

The design and application of a personal printer/scanner system

Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1985.MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH.Includes bibliographical references (leaves 44-47).A prototype system for concurrent printing and scanning of documents has been constructed. By taking a personal computer ink-jet printer and modifying it to include a line-scan sensor, major benefits are derived. Both conventional printers and scanners contain mechanisms for moving either documents, sensors or mirrors. Combining a printer and a scanner into a single device offers a potential reduction in cost because the printer's mechanisms then serve a double duty. A scanner makes available to the personal computer user established commercial applications such as image digitization and facsimile. Moreover, unique document processing features are possible when a scanner is present in a printing device. With documents already containing some information, intelligent printing annotation can be performed. For example, a previously scanned and digitized picture can be printed on a new document already containing text and open space. Scaling, positioning and printing of the digitized picture to fit within the open space is archived through scanning and analyzing the new document. The physical and functional characteristics of the printer/scanner system are described. Principles relevant to the design, construction and application of the printer/scanner are given, and present and future applications discussed.by Jeffrey David Keast.M.S.V.S

PRESERVATION FOR FUTURE GENERATIONS: DIGITAL TECHNOLOGIES, DIGITALIZATION, AND EXPERIMENTS WITH CONSUMERS AS PRODUCERS OF INDUSTRIAL HERITAGE DOCUMENTATION

As digital documentation and recording technologies have evolved, so has the perception that they are segregated and intended primarily for use in either engineering/scientific or amateur/consumer applications. In contrast to this notion, the three-dimensionality afforded by these technologies differs only when considering them in the order of priorities; laser scanners and related image acquisition technologies document and visualize while inversely, consumer cameras visualize and document. This broad field of digital acquisition technologies has evolved into a heterogeneity of tools that all capture aspects of the physical world with a line drawn between them becoming blurred. Within this evolution, these tools are becoming less expensive, easier to use, and depending upon the application, can be operated successfully by individuals having modest or semi-professional skills. The proliferation of digital documentation technologies, the ease of their use, and the ability to share visual data on the internet allow us to examine the inclusion of digital documentation into the preservation management of historic industrial resource, pushing heritage to the digitalized culture
