Abstracts on Radio Direction Finding (1899 - 1995)

The files on this record represent the various databases that originally composed the CD-ROM issue of "Abstracts on Radio Direction Finding" database, which is now part of the Dudley Knox Library's Abstracts and Selected Full Text Documents on Radio Direction Finding (1899 - 1995) Collection. (See Calhoun record https://calhoun.nps.edu/handle/10945/57364 for further information on this collection and the bibliography). Due to issues of technological obsolescence preventing current and future audiences from accessing the bibliography, DKL exported and converted into the three files on this record the various databases contained in the CD-ROM. The contents of these files are: 1) RDFA_CompleteBibliography_xls.zip [RDFA_CompleteBibliography.xls: Metadata for the complete bibliography, in Excel 97-2003 Workbook format; RDFA_Glossary.xls: Glossary of terms, in Excel 97-2003 Workbookformat; RDFA_Biographies.xls: Biographies of leading figures, in Excel 97-2003 Workbook format]; 2) RDFA_CompleteBibliography_csv.zip [RDFA_CompleteBibliography.TXT: Metadata for the complete bibliography, in CSV format; RDFA_Glossary.TXT: Glossary of terms, in CSV format; RDFA_Biographies.TXT: Biographies of leading figures, in CSV format]; 3) RDFA_CompleteBibliography.pdf: A human readable display of the bibliographic data, as a means of double-checking any possible deviations due to conversion

Tracking and data relay satellite system configuration and tradeoff study. Volume 5: TDRS spacecraft design, part 1

A dual spin stabilized TDR spacecraft design is presented for low data rate (LDR) and medium data rate (MDR) user spacecraft telecommunication relay service. The relay satellite provides command and data return channels for unmanned users together with duplex voice and data communication channels for manned user spacecraft. TDRS/ground links are in the Ku band. Command links are provided at UHF for LDR users and S band for MDR users. Voice communication channels are provided at UHF/VHF for LDR users and at S band for MDR users. The spacecraft is designed for launch on the Delta 2914 with system deployment planned for 1978. This volume contains a description of the overall TDR spacecraft configuration, a detailed description of the spacecraft subsystems, a reliability analysis, and a product effectiveness plan

Nimbus 6 Random Access Measurement System applications experiments

The advantages of a technique in which data collection platforms randomly transmit signal to a polar orbiting satellite, thus eliminating satellite interrogation are demonstrated in investigations of the atmosphere; oceanographic parameters; Arctic regions and ice conditions; navigation and position location; and data buoy development

Exploring an open-loop RFID implementation in the automotive industry

This master thesis has been conducted to investigate why and how Plastal in Arendal (PAGO), Sweden have implemented RFID technology. RFID technology has become very popular in recent years (1). It is said to have potential to increase the level of automation (2), reduce the labor levels and to improve the supply chain in areas such as inventory, visibility etc. (3) (see chapter 1.2.1 for more examples). PAGO is one of the first major companies in Sweden that have implemented an open-loop RFID system (see chapter 1.2.3.2) that tag on item level. They are also a supplier of injection-molded and surface-treated plastic to the automotive industry; an industry that is characterized by high level of automation and fierce competition. It is thus very interesting to investigate why and how PAGO implemented RFID technology; did any problem arise? How did they solve them? What where their underlying reasons? To minimize the errors caused by manual updating – resulting in incorrect storage levels – PAGO have implemented a RFID system. The system has 24 RFID gates, divided into seven places: injection molding, entry and exit point of high storage 1, paint shop, entry and exit point of high storage 2 and after the sequencing process. The RFID system will help reduce the effects of entering the wrong quantity at the entry and exit point for high storage 1 and 2. It will also reduce the effects of specifying the wrong color or product. Furthermore, it will also help them verifying that each product is correctly assembled. During the implementation, PAGO encountered some problems with ESD, reading too much or too little, tags becoming partially or completely detached and a long installation time. Most of these problems have been fixed but some of them remain. There exist several reasons why PAGO implemented a RFID system, other than verifying the assembly and minimizing the effect caused by manual updating. One of those is believed to be because of the nature of the company – They only have 8h to sequence deliver the order, high turnover rates with expensive products and highly automated processes. Another reason is that RFID was a solution that solved both of their specified problems, but also supplying them with more features. Other reasons are that it will probably become a demand from Volvo in the future and that the technology is more future proof than any other technology that would have solved their problem; it is for example believed to be the successor of barcode. Major advantages, both visible and hidden, can be achieved with this RFID implementation. More reliable inventory levels could for example reduce the safety stock level, increase the level of automation and reduce the number of incorrectly assembled products sent to Volvo and thus increase their relationship

Harnessing nature's timekeeper: a history of the piezoelectric quartz crystal technological community (1880-1959)

In 1880, French brothers Jacques and Pierre Curie discovered the phenomenon of piezoelectricity in naturally occurring quartz crystal, sometimes referred to as 'nature's timekeeper.' By 1959, tens of millions of devices that exploited quartz crystal's piezoelectric character were being used in the technologies of radio, telephony, and electronic timekeeping. This dissertation analyzes the rapid rise of quartz crystal technology in the United States by looking at the growth of its knowledge base as reflected primarily in patents and journal articles. The major finding of this analysis is that the rise of quartz crystal technology cannot be fully understood by looking only at individuals, institutions, and technological factors. Rather, this work posits that the concept of technological community is indispensible in explaining rapid technological growth and diffusion that would otherwise seem inexplicable. In the late 1920s, and again in the early 1940s, the knowledge base of quartz crystal technology experienced exponential growth, partly due to U.S. government patronage and enlightened regulation. However, as this study shows, quartz crystal engineers, scientists, and entrepreneurs could not have mobilized as quickly and effectively as they did unless a vibrant technological community already existed. Furthermore, the United States' ability to support such a thriving community depended in part on an early 20th century American culture that displayed an unmatched enthusiasm for democratic communications media, most especially broadcast radio and universal telephone service. Archival records, professional journal articles, government reports, manufacturer catalogs, and U.S. patents have been used to document this history of the quartz crystal technological community. This dissertation contributes to the literature on technological communities and their role in facilitating technological and ecomonic growth by showing that though such communities often form spontaneously, their growth may be nurtured and stimulated through enlightened government regulation. As such, this dissertation should be of interest to scholars in the fields of history of technology, business history, management studies, and public policy.Ph.D.Committee Chair: Usselman, Steven; Committee Member: Ceccagnoli, Marco; Committee Member: Giebelhaus, August; Committee Member: Hunt, William; Committee Member: Krige, Joh
