An investigation of computerized information storage and retrieval methods, in a film library organized according to the universal decimal classification

The operation of the BBC Film Library was studied with the intention of defining those areas likely to benefit from computerization. The state of the art of computerized information retrieval was assessed by means of the literature, and those techniques likely to be of use at the Film Library were isolated. Computer programs were written to provide an information storage and retrieval system paralleling the manual system currently used at the Film Library, organized according to the UNIVERSAL DECIMAL CLASSIFICATION (UDC). These programs were operated by the film librarians in situ. A computerized system able to "learn" from enquiries was built and tested, and document clustering was also investigated as a method of subject classification. A modular approach to retrieval system design was developed within the framework of a Relational Database system, so that the various retrieval methods examined in the course of the study could be cemented into one concertive retrieval system

A History of Materials and Technologies Development

The purpose of the book is to provide the students with the text that presents an introductory knowledge about the development of materials and technologies and includes the most commonly available information on human development. The idea of the publication has been generated referring to the materials taken from the organic and non-organic evolution of nature. The suggested texts might be found a purposeful tool for the University students proceeding with studying engineering due to the fact that all subjects in this particular field more or less have to cover the history and development of the studied object. It is expected that studying different materials and technologies will help the students with a better understanding of driving forces, positive and negative consequences of technological development, etc

Accomplishments include: development of computing programs for mission science and data analysis, supercomputer applications support, computer network support, computational upgrades for data archival and analysis centers, end-to-end management for mission data flow, scientific modeling and results in the fields of space and Earth physics, planning and design of GSFC VO DAAC and VO IMS, fabrication, assembly, and testing of mission instrumentation, and design of mission operations center

Reading the local paper: Social and cultural functions of the local press in Preston, Lancashire, 1855-1900

This thesis demonstrates that the most popular periodical genre of the second half of the nineteenth century was the provincial newspaper. Using evidence from news rooms, libraries, the trade press and oral history, it argues that the majority of readers (particularly working-class readers) preferred the local press, because of its faster delivery of news, and because of its local and localised content. Building on the work of Law and Potter, the thesis treats the provincial press as a national network and a national system, a structure which enabled it to offer a more effective news distribution service than metropolitan papers. Taking the town of Preston, Lancashire, as a case study, this thesis provides some background to the most popular local publications of the period, and uses the diaries of Preston journalist Anthony Hewitson as a case study of the career of a local reporter, editor and proprietor. Three examples of how the local press consciously promoted local identity are discussed: Hewitson’s remoulding of the Preston Chronicle, the same paper’s changing treatment of Lancashire dialect, and coverage of professional football. These case studies demonstrate some of the local press content that could not practically be provided by metropolitan publications. The ‘reading world’ of this provincial town is reconstructed, to reveal the historical circumstances in which newspapers and the local paper in particular were read. Evidence from readers demonstrates the many ways in which they used the local press, both collectively and individually, including its use in sustaining local identities and sense of place. However, the local press was only one factor among many in the development and sustenance of local identities. The originality of the thesis lies in its introduction of empirical reading evidence into English newspaper history, its challenge to the taken-for-granted but problematic concepts of ‘local’ and ‘national’ newspapers in this period, its detailed study of the journalistic techniques used to capitalise on local patriotism, and its critique of many theories of nineteenth-century press history which have been based on a minority of the period’s newspapers, those published in London

Data Hiding and Its Applications

Data hiding techniques have been widely used to provide copyright protection, data integrity, covert communication, non-repudiation, and authentication, among other applications. In the context of the increased dissemination and distribution of multimedia content over the internet, data hiding methods, such as digital watermarking and steganography, are becoming increasingly relevant in providing multimedia security. The goal of this book is to focus on the improvement of data hiding algorithms and their different applications (both traditional and emerging), bringing together researchers and practitioners from different research fields, including data hiding, signal processing, cryptography, and information theory, among others

Third International Symposium on Space Mission Operations and Ground Data Systems, part 2

Under the theme of 'Opportunities in Ground Data Systems for High Efficiency Operations of Space Missions,' the SpaceOps '94 symposium included presentations of more than 150 technical papers spanning five topic areas: Mission Management, Operations, Data Management, System Development, and Systems Engineering. The symposium papers focus on improvements in the efficiency, effectiveness, and quality of data acquisition, ground systems, and mission operations. New technology, methods, and human systems are discussed. Accomplishments are also reported in the application of information systems to improve data retrieval, reporting, and archiving; the management of human factors; the use of telescience and teleoperations; and the design and implementation of logistics support for mission operations. This volume covers expert systems, systems development tools and approaches, and systems engineering issues
