Full textAbstract:
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, NevadaThe MARS-II digital recorder is one of the new technologies that will eventually replace the labor intensive and hardware dependent methods associated with traditional analog-based telemetry ground systems. The Standardized MARS-II Analysis and Reduction Tool (SMART) is one of the first software systems developed to take advantage of this new digital recording capability. It processes pulse code modulated (PCM) encoded data and MIL-STD-1553B message traffic, outputting time-tagged PCM frames or 1553 messages to file. The goal of this software is to provide a portable application that utilizes state-ofhe-art, general purpose hardware for rapid telemetry data processing to meet the needs of operational users, telemetry engineers, and data analysts. To satisfy these goals, the software was developed using the C language with VMS and OSF operating systems as the initially targeted platforms. In addition, an X Window System/Motif graphical user interface supporting three tiers of user interaction (operator, telemetry engineer, and telemetry analyst) was layered onto the decommutator functions.

Full textAbstract:
For many years, speech recognition threshold (SRT) testing has been used as an indicator of audiologic health. However, with changing methods and technology, test-retest reliability has not been reviewed extensively with newer digitally recorded spondaic words which meet a published criterion of listener familiarity. This study examined the test-retest reliability of 33 high frequency usage and psychometrically equated spondaic words. The American Speech-Language-Hearing Association recommended method (2-dB decrements) was used to measure the left and right SRT of 40 participants using both male and female talker recordings. For each participant, four SRTs were found during the test condition and four SRTs were found during the retest condition. All of the SRT scores were analyzed and the averaged SRT values found using a male talker recording resulted in an average retest SRT to be 1.4 dB better than the average test SRT. The averaged SRT values found using a female talker recording resulted in an averaged retest SRT to be 1.2 dB better than the averaged test SRT. The SRT scores also showed high validity when compared to each participant's pure tone average (PTA). This study additionally found no significant interaction in using a male versus a female talker when using digitally recorded and psychometrically equated spondaic words.

Full textAbstract:
The purpose of this study was to determine the test-retest reliability of digitally recorded word recognition materials. Word recognition testing is included in a complete audiological evaluation to measure an individual's ability to discriminate what they hear. A phonetically balanced list of 50 monosyllabic words was presented to each participant at four different sensation levels (SL) using the American Speech Language Hearing Association recommended protocol for word recognition score testing. Each participant took a 10 minute break before the test was readministered. Participants included 40 subjects with varying levels of hearing loss, from normal hearing to severe hearing loss. The test and retest scores of all participants were analyzed to estimate the test-retest reliability to be .65 at 10 dB SL, .87 at 20 dB SL, .88 at 30 dB SL, and .95 at 40 dB SL. It was concluded that the word lists have strong test-retest reliability at 20, 30, and 40 dB SL and that the reliability increases as the presentation level increases.

Full textAbstract:
The purpose of this study was to evaluate an updated list of digitally recorded Speech Recognition Threshold (SRT) materials for test-retest reliability. Chipman (2003) identified 33 psychometrically equated spondaic words that are frequently occurring in English today. These digitally recorded words were used to determine the SRT of 40 participants using the American Speech-Language Hearing Association guidelines. The participants were between the ages of 19 and 83 years and presented with hearing impairment ranging from normal to severe. The individual's pure-tone averages classified 16 participants with normal hearing to slight loss, 12 participants with mild loss, and 12 participants with moderate to severe hearing loss. The speech materials were presented to participants in one randomly selected ear. The SRT was measured for the same ear in both the test and retest conditions. The average SRT for the test condition was 22.7 dB HL and 22.8 dB HL in the retest condition with an improvement of 0.1 dB for retest but no significant difference was identified. Using a modified variance equation to determine test-retest reliability resulted in a 0.98, indicating almost perfect reliability. Therefore the test-retest reliability was determined to be exceptional for the new SRT words.

International Telemetering Conference Proceedings / October 26-29, 1987 / Town and Country Hotel, San Diego, CaliforniaThe conventional IRIG Instrumentation Tape Recorder has two major disadvantages when used to record and reproduce digital data. Firstly it has a limited number of discrete tape speeds, and secondly the operator has to calculate and then set the tape speed to give the appropriate packing density or clock rate. The use of microprocessors has made it possible to take the majority of these calculations, and also the setting up of the recorder, out of the users hands. Also the tape speeds available are virtually continuous over the range 17/8 ips to 120 ips. There are other facilities available and this paper describes the operation and facilities of an instrumentation recorder which is almost totally automatic.

This thesis describes the design and testing of a floppy disk drive based digital recorder. The device was originally built for a geomagnetic research project, but is also suitable for other phenomena with time scales from fractions of a second to approximately one day. The system is designed specifically to improve the reliability for long-term observing programs and to enhance the efficency of the subsequent data analysis procedures. Using an STD-Z80 BUS microcomputer, under the control of a Forth language program, the recorder stores digital data on removable 8-inch floppy disks. This thesis explicitly addresses the issue of cost and provides the necessary detail for reproduction of the device. A procedure is described for preparing the acquired data for analysis using computing facilities equiped with an appropriate disk reader. Also presented is a quantitative and qualitative evaluation of the recorder's performance when applied to both synthetic and natural signals. The latter include geomagnetically induced currents in power transmission lines.Science, Faculty of

The recorder was developed for use in the aircraft company's Portable Airborne Digital Data System (PADDS), a small scale data acquisition and monitor system used for flight testing. The recorder is designed around an off-the-shelf 8mm tape drive, the Exabyte 8505. It records asynchronous, variable-rate data in a proprietary 24-bit recording format, and allows the data to be played back in real time. Its RS-422 control interface is designed to imitate the recorder used in the company's large scale data acquisition system, the Ampex DCRSi-II. Special provisions allow it to withstand the environment of an airplane's EE bay.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, NevadaRecorders conforming to IRIG Standards have served the data recording community well for many years. Initially, most systems were analog in nature, recording data in either direct or FM modes but as the need for digital recording developed, the IRIG recorder was successfully adapted for this purpose by the addition of formatting and coding sub-systems to form the High Density Digital Recorder (HDDR). Today, user requirements for higher speed, higher capacity and more convenient systems have presented equipment designers with new challenges in terms of the correct choice of technology and system architecture. It is not surprising that system designers should turn for inspiration first to the very high speed transverse and helical products which had been developed for the broadcast industry since these technologies possess many of the attributes necessary for a high rate digital data recorder. It is unfortunate that it has now become a truism that the only logical progression from the longitudinal IRIG system is by means of rotary technology. Recent developments in a technology known as micro-track recording now call this assumption into question. Recording systems based on micro-track technology are available and others are in an advanced state of development, and these offer a costeffective, attractive and low risk alternative to rotary systems for both high rate data capture and tape mass storage applications.

Record companies are suffering due to a downturn in recorded music sales. Innovative firms have developed digital music services that offer recorded music products to customers in new ways, yet sales are not what they used to be. Web 2.0 technologies have changed the customer’s tastes, expectations, and desires. Thus, a deeper understanding of the new “digital customer” is needed in order to better offer services in a way that he or she prefers most.

Full textAbstract:
The writings of Yuk Hui, bringing together technical and philosophical insights, provides new theory for the digital, something desired by many in archival research. The aim of this study is to assess the use of Hui’s theories on digital objects and web ontologies as a unifying theory for archival studies, looking at the concept of digital records in particular. Two types of ontology are needed in order to understand digital objects according to Hui: (1) ontologies which relates to the technical language and hierarchies of knowledge representation, like metadata; (2) Ontology, which is the question of Being in the tradition of Heidegger’s phenomenology, the understanding of what it is to be in the world. Both of these ontologies are needed to account for the nature of the digital object. Further, digital objects are produced and constituted through their relations, which can be divided into discursive (technical and logical) and existential (the understanding of being in the world) relations. Digital objects must be approached both as technical formal entities, and as beings in the world. The first register is common, the second – more existential approach – is rarely applied. Using a metatheoretical and hermeneutic method, different conceptions of digital records are discussed, in order to find commonalities and possibilities in relation to Hui’s theory. The digital record as: a process of becoming, information as affordance, context, temporality and evidence are all related to and structured through the application of Hui’s perspective. The thesis ends with the contribution of a possible redefinition of digital records: A digital record is constituted and concretised as material by discursive and existential relations, that taken together function as a persistent representation. Further, Hui’s digital object theory is suggested as a structuring and unifying theory. In relation to digital records Hui’s theory on digital objects can function as a metatheoretical measure, and a method of critical reading.Yuk Hui för samman tekniska och filosofiska perspektiv och erbjuder ny teori för det digitala, något som ofta efterfrågas inom arkivvetenskapen. Syftet med denna studie är att applicera Huis teori om digitala objekt och webontologier som en förenande teori för arkivstudier, specifikt i förhållandet till konceptet digitala records. Två typer av ontologi behövs för att förstå digitala objekt enligt Hui: (1) ontologier som relaterar till tekniskt språk och hierarkiska kunskapsrepresentationer, så som metadata; (2) Ontologi som frågan om varat i fenomenologen Martin Heideggers bemärkelse; förståelsen av vad det är att vara i världen. Båda dessa ontologier behövs för att redogöra för det digitala objektets natur. Vidare produceras och konstitueras digitala objekt genom sina relationer, som kan delas upp i diskursiva (tekniska och logiska) och existentiella (förståelsen av att vara i världen) relationer. Digitala objekt måste förstås både som tekniska formella entiteter och som varelser i världen. Det första perspektivet är vanligt förekommande medan det andra – mer existentiella förhållningssättet – sällan tillämpas. Med hjälp av en metateoretisk och hermeneutisk metod diskuteras olika föreställningar om digitala records för att hitta likheter och möjligheter i relation till Huis teori. Digitala records som: en process av tillblivande, information som affordance, kontext, temporalitet och bevis är koncept som relateras och struktureras genom tillämpningen av Huis perspektiv. Uppsatsen bidrar med en möjlig omdefinition av digitala records: Ett digitalt record konstitueras och konkretiseras som materiellt genom diskursiva och existentiella relationer vilka, tillsammans, fungerar som en ihållande representation. Vidare framhålls Huis teori för digitala objekt som en strukturerande och förenande teori. I relation till digitala records kan Huis teori om digitala objekt fungera som ett metatoretiskt mått och en metod för kritisk läsning.

Full textAbstract:
This thesis centres on the P2P internet protocol BitTorrent, music filesharing, and nascent forms of collective action developing through private BitTorrent communities. The focus is on one of these communities, a music filesharing website called ‘OiNK’. Founded in 2005, it was the first of its kind to garner membership in the hundreds of thousands, was emblematic of user-led movements to improve the quality, efficiency and availability of digital media online, and was very publically shut down in 2007. Making critical use of Simondon’s notion of ‘individuation’, two interrelated techno-historical impulses are identified as central to the ‘in-formation’ of both BitTorrent and OiNK. Firstly, through research into the development of the global music industry’s ‘productive circuit’ of manufacturing, distribution, retail and radio, it is shown how consumers were gradually excluded from having a say in how, what and where they could consume. Secondly, a history of ‘OiNK-style’ filesharing is gleaned, not from P2P, but from research into small, decentralised ‘online’ communities that emerged throughout the 1980’s and 1990’s, where enthusiasts learned how to use software and hardware to manage the storage, reproduction, uploading and sharing of information. This thesis shows how BitTorrent exposed these previously exclusive practices to masses of consumers who were dissatisfied with both retail/broadcasting and public P2P, through the new possibility of private BitTorrent communities. Through a case study of OiNK, encompassing in-depth interviews with ex-members, screenshots and technical analysis, this thesis shows how OiNK gathered a large and diverse online cache of ‘archival grade’ recorded music, bringing old and deleted music back into circulation and amassing a core of fanatically committed members. It accounts for a nascent form of online community, where large member-bases manage every aspect of the reproduction and circulation of digital artefacts, and at higher levels of quality/efficiency than legal alternatives.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaThe world of instrumentation data recording has traditionally been concerned with recorder performance in terms of bandwidth, data rate, tape speed and recording time, with the apparently unceasing trend to record more and more data. However, while this may remain a valid perspective for data acquisition, the increasing requirement to integrate equipment into computer based environments has resulted in the need for greater emphasis to be applied to such parameters as data control and interfacing when specifying digital data recording systems. This paper addresses these operational issues and describes the practical implementation of a computer friendly digital cassette recorder which provides a common platform for both high rate data acquisition and computer based data analysis.

A large part of commercial computer technology development is based on increased size and decreased cost of memory devices, from which the instrumentation community can derive great benefit through the development of solid state systems. The procurement cost of new solid state systems utilizing increased memory capability makes the temptation to move to this technology unavoidable. There are, however, some issues that need to be discussed which go beyond procurement costs and involve operational and life cycle considerations.

Transport properties of a standard compact - cassette tape system are measured and software techniques devised to configure a low - cost,direct digital recording system. Tape - velocity variation is typically ± 10% of standard speed over tape lengths of 5 µm.with occasional variations of ±40%. Static tape - skew can result due to axial movement of the tape reel when it spools.Dynamic tape skew occurs and is primarily caused by tape - edge curvature with a constant contribution due to the transport mechanism.Spectral skew components range from 0.32 Hz to 8 Hz with magnitude normally within one 10 kbit/ sec- bit cell.The pinch roller works against the friction of the tape guides to cause tape deformation.Average values of tape deformation are 0.67 µm,0.85 µm and 1.08 µm for C60,C90 and C120 tape respectively. Parallel,software encoding / decoding algorithms have been developed for several channel codes.Adaptive software methods permit track data rates up to 3.33 k bits/sec in a rnultitrack system using a simple microcomputer.For a 4 - track system,raw error rates vary from 10ˉ⁷ at 500 bits/sec/track to 10ˉ⁵ at 3.33 kbits/sec/track.Adaptive software reduces skew - induced errors by 50%.A skew - correction technique has been developed and implemented on an 8 - track system at a track data rate of 10 k bits/sec. Real - time error correction gives a theoretical corrected error rate of 10ˉ¹¹for a raw error rate of 10ˉ⁷. Multiple track errors can cause mis - correction and interleaving is advised. Software algorithms have been devised for Reed - Solomon code. With a more powerful microprocessor this code m ay be combined with the above techniques in a layered error-correction scheme. The software techniques developed may be applied to N tracks with an N - bit computer.Recording density may be increased by using thin - film,multitrack heads and a faster computer.

Abstrakt Den snabba tekniska utvecklingen har lett till ökad produktion av digitala handlingar/records och transaktioner. Inom e-arkivens domäner, har detta medfört ett ökat tryck på det tekniska området för att kunna garantera autenticitet av bevarad information över tid. Tidsstämplingstekniker är ett sätt att säkerställa digital information för en särskild tidpunkt och kan användas för att garantera autenticitet av digital information över tid. Denna magisteruppsats undersöker funktionen tidsstämpling inom e-arkivens domäner genom en kvalitativ metod med fem semistrukturerade intervjuer av fem svenska organisationer. I undersökningen ingår också en fallstudie av det svenska innovationsföretaget Enigio Time AB för att ge en förståelse av tidsstämplingstekniker och av deras tjänst time:stamp. Den teoretiska utgångspunkten i denna magisteruppsats är records continuum model med dels dess syn på kontinuitet i handlingar/records och dels dess belysande av skapelseögonblicket av handlingar/records. Den internationella standarden OAIS (Open Archival Information System) används för att hantera digital information och är, i denna uppsats, använd för att analysera hanteringen i dokumenthanteringssystem inom de fem organisationerna. Resultaten visar att denna snabba tekniska utveckling har komplicerat dels hanteringen i att säkerställa att digitala handlingar/records inte kan bli manipulerade eller ändrade och dels för att fortsatt kunna garantera autenticitet i ett långtidsperspektiv. Undersökningen visar även att organisationerna kan garantera att det bevarade materialet inte kommer att ändras när det väl är inne i arkivet men dess autenticitet, innan de kommer innanför arkivens trösklar, kan aldrig bekräftas. I och med att den moderna tiden producerar och bevarar enorma mängder data så bör detta starta med skapelsen av ett digitalt record tillsammans med bättre strukturerad metadatascheman som är säkrade i tid.Abstract The rapid ongoing technical development has led to increased production of digital records and transactions. In the domain of electronic archives, this has put pressure on the technical area in order to guarantee authenticity of preserved information over time. Time stamping techniques are one way to secure digital information at a certain point in time and can be employed to guarantee authenticity of digital information over time. This study examines the function of time stamping within the domain of electronic archives and is conducted with a qualitative method using semi-structured interviews on five Swedish organisations. The study is complemented with a case-study of the Swedish innovation company Enigio Time AB in order to gain understanding in time stamping techniques and their service time:stamp. The theoretical framework in this study is the records continuum model with the view of the continuity in records and its illumination of the point of creation. The international standard OAIS (Open Archival Information System) is used by several electronic models to manage digital information and is, in this study, used to analyse the management in record keeping within the five organisations. The conclusion is that this rapid technological development has complicated the management of secure digital records from manipulation and guaranteeing the authenticity in a long term perspective. The study further shows that organisations may guarantee that records will not change once they are received into the archive but the authenticity of them, before they were delivered, can never be confirmed. Since the modern information era produces and preserves enormous amounts of data, this has to start with the creation of the digital record where better structured metadata schemes are secured in time.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, CaliforniaOn reviewing current PCM on-board data acquisition systems design is not very uncommon to find lots of useful signals being generated together with the PCM stream, such as bit clocks, word clocks, minor and major frame pulses. The purpose of this paper is to demonstrate a conceptual design of a digital recording device that takes advantage of these signals to collect data directly into a computer compatible disk file. Such device can eliminate the need of further PCM signal processing after the test and speed up the conversion process of pure digital sampling values into floating point numbers.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe increasing availability of powerful yet relatively inexpensive data acquisition and processing techniques has precipitated a radical reappraisal of the methods used to capture, manipulate and store data of all kinds. Some of the recently introduced recording systems can be used both for fast data capture and for high capacity archival/back-up applications - effectively bridging a long-standing divide between these two formerly diverse aspects of data recording and processing. This paper offers a brief overview of a new technology known as micro-track recording, and suggests ways in which system designers and integrators may take full advantage of its important new facilities and features.

The images captured in and out of aircraft have excessive movement-related issues, which make the results difficult to analyze and interpret. Failure to remove the tremors in the video component inevitably leads to poor compression efficiency and degrades the video imaging performance in the airborne black box. Therefore, it is necessary to develop a Compression System which can stabilize the video-image and efficiently utilize high compression recording for aircraft without special hardware. Based on the current situation, we suggest a real-time electronic video stabilization algorithm for airborne recorder which recovers shaky images simply and efficiently to work beside a developed stabilization system based on the H.264 Encoder using DSP.

Luyombya, D. "Framework for effective public digital records management in Uganda." Thesis, University College London (University of London), 2010. http://discovery.ucl.ac.uk/19354/.
Full textAbstract:
This thesis examines the framework for effective management of digital records in Uganda, which was undertaken by a detailed study of the 23 ministries, which form the Uganda Public Service (UPS). Areas of research inquiry included establishing the current state of digital records in the UPS and revealing the factors impeding the managing of digital records. This raised many issues about the way in which digital records are created, maintained and used, including possible lines of action to resolve current digital records management (DRM) problems. It also considered how the DRM services and practices used elsewhere could be adopted to suit the UPS environment. The status of DRM and the factors affecting the creation, use, maintenance and disposition of digital records were critically reviewed and evaluated and, towards the end, the thesis recommends strategies and makes proposals that could contribute to the development of DRM services in the UPS. The study adopted a mixed methods research approach and drew on the ‘records continuum’ concept for its analytical framework. The study drew on data from primary and secondary (literature and research reports) sources. Data collection from primary sources was carried out using questionnaires and semi-structured interviews, which made it possible to study the personal perspectives and experiences of those involved in the management of records and of digital systems in Uganda. The approach provided insight into the UPS ministries, where data was collected from senior and middle managers, ICT managers and records managers, through a total of 40 interviews. This approach was essential in so far as it focused on the importance of the meanings that emerged as respondents defined their DRM requirements through interpersonal interactions and it guided the data collection, analysis and reflection activities. The analysis of the findings of the study revealed that the problems with DRM are largely due to the absence of ICT facilities with recordkeeping functionality, a lack of clear policies, guidelines and procedures, and to the fact that the Uganda Records and Archives legislation is not fully implemented and not properly enforced. It is argued that the failure to fully implement the National Records and Archives Act has led to a lack of appropriate institutional and managerial structures. Other problems include the lack of a reliable power supply and of sufficient financial resources and human capacity. Although no UPS ministry has a complete Electronic Document and Records Management System (EDRMS), the survey of many ministries provided comprehensive evidence of the dynamism in the use of ICT that led to the generation of digital records. The problems and challenges elaborated upon in the study have shown that a successful DRM service depends on a number of factors. While it is not strictly possible to generalise the findings from this purposive sample to the whole of the Government of Uganda, it is likely that the issues identified in this study will apply to the whole of the Uganda public sector and, to some extent, to other sub-Saharan African countries. The study concludes that in order to facilitate a DRM service in the UPS, the objective should be to enable increased creation and keeping of records by digital means. The proposed recommendations are categorised into four key factors: the need for formal legal infrastructure; the need to establish formal instruments in particular a national archives agency with appropriate policies, procedures and guidelines; and the development of both robust DRM infrastructure and of appropriately skilled human resource capacity. These factors are necessary and need to be addressed urgently, and specifically for Uganda, in order to ensure accountable government for the citizens of Uganda in the digital world.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, NevadaMany telemetry stations would like to convert from using digital-to analog converters (DAC's) to using direct digital inputs to their chart recorders but can't find a suitable recorder interface. These stations often have hundreds or even thousands of channels of information being bussed around at very high speeds on propriatary real-time computer systems. The lack of standardization has naturally presented recorder manufacturers with problems in selecting the appropriate interface hardware. Standard parallel interfaces, such as SCSI and GPIB, are usually too slow and not really suited for real-time transfer, although they can be used in some circumstances which will be described. The best choice seems to be a general purpose parallel port of at least 16 data bits which can support a large number of addresses. Such an interface can be used with a high speed network like SCRAMNet as well as with a general purpose computer or workstation. This paper will describe several available parallel ports using both TTL and RS-485 (long-line) hardware and some practical implementations of thermal array recorder use with SCRAMNet, GPIB, and general purpose parallel busses.

Full textAbstract:
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, CaliforniaModern High Density Digital Recorders (HDDR) are ideal devices for the storage of large amounts of digital and/or wideband analog data. Ruggedized versions of these recorders are currently available and are supporting many military and commercial flight test applications. However, in certain cases, the storage format becomes very critical, e.g., when a large number of data types are involved, or when channel-to-channel correlation is critical, or when the original data source must be accurately recreated during post mission analysis. A properly designed storage format will not only preserve data quality, but will yield the maximum storage capacity and record time for any given recorder family or data type. This paper describes a multiplex/demultiplex technique that formats multiple high speed data sources into a single, common format for recording. The method is compatible with many popular commercial recorder standards such as DCRsi, VLDS, and DLT. Types of input data typically include PCM, wideband analog data, video, aircraft data buses, avionics, voice, time code, and many others. The described method preserves tight data correlation with minimal data overhead. The described technique supports full reconstruction of the original input signals during data playback. Output data correlation across channels is preserved for all types of data inputs. Simultaneous real-time data recording and reconstruction are also supported.

Full textAbstract:
This thesis aims to understand transcription as a critical transmission practice in the digital medium in order to add to the research surrounding digital library initiatives that make these research materials available and accessible. The project to transcribe the records of Lapland priest J. A. Nensén at Umeå University aims to publish the transcriptions in the cultural heritage database Alvin by Uppsala University Library. Looking at these two Swedish projects can better illustrate the issues surrounding digital tool application and integration. This thesis first explores the transcription practices of a group of scholars transcribing J. A. Nensén’s records. By understanding their model, a better picture of transcription as a scholarly practice can be achieved that can be useful when selecting a digital transcription tool. The study then identified appropriate transcription tools and reviewed the ones most applicable for the project based on the group’s paradigm. It was discovered that the main disparity in transcription practice is the balance between producing a diplomatic transcription and one that is readable. The primary consideration in transcription tool selection was found to be the goals of the project; in this case, those of the transcribers. This determined the tools to be reviewed. These were: FromThePage, Scripto, T-Pen, and Wikisource. All the tools are suitable to the editors, but they still present some obstacles in regards to diplomatic transcription.

The Swedish National Archives are in charge of the management of Common Specifications (CS). CS are genericmetadata specifications that provides structure and markup when transferring digital information betweeninformation systems and to electronic archives. As of now there is no CS for electronic healthcare records (EHR).Organizations around Sweden have developed their own specifications for transferring healthcare information. Inaddition to that, there are comprehensive international EHR metadata standards established. The Swedish NationalArchives have commissioned a study of EHR metadata specifications and standards to aid in the development of theCS.A Delphi study was conducted, including respondents from major archiving organizations in Sweden, to identifynecessary metadata categories when exchanging EHRs. The data was analyzed considering the international EHRmetadata standards HL7 CDA2 and CEN/ISO EN13606, as well as digital preservation metadata categories. Theresults were a set of metadata categories necessary to include in a CS. In addition, a subset of suggested mandatorymetadata categories is proposed and a list of implications for practice. Clinical codes, auditing, and separatingmetadata related to different contexts are a sample size of the implications.The results were evaluated in an interview with the Swedish National Archives, as well as Sydarkivera. Three criteriafor evaluating the results were proposed, being that the results had to consider a common terminology as well as bebased on a metadata standard and Swedish metadata specifications for EHRs. The interview revealed that the resultssatisfied these criterions, except for requiring a study on one additional user environment of EHRs.

Full textAbstract:
The assessment and protection of the authenticity of digital records and data are recognized as fundamental issues for the records’ current use as well as for their long-term preservation and dissemination. Over the past twenty years, the matter of how to define, determine, and guarantee the endurance of authenticity has been the subject of research in all evidence-based or memory-based disciplines, including archival science, digital humanities, and law. Despite the wealth of past and current research findings, recommendations, and tools, authenticity is still discussed as an urgent problem for records and data created and maintained in traditional digital technologies as well as in emerging ones, such as cloud technologies, and embedded or wearable technologies.
This study investigates contemporary ideas about authenticity of records and data, and practices employed by records professionals. Based on the archival idea that record authenticity is assessed by establishing its identity and proving its integrity, this study identifies indicators for authenticity and categorizes them as either social or technical mechanisms. Using a mixed methods design, it measures how records professionals ensure, manage, and continuously assess record authenticity and to what extent their practices reflect the results of available research. A web-based survey reached records professionals worldwide through professional listservs, and semi-structured interviews gathered further qualitative data from a sample drawn from the survey respondents.
The results show that the standard archival definition of authenticity is not uniformly accepted or implemented in practice, and terms such as authenticity, reliability, integrity, and provenance are often used interchangeably and with little precision. They also reveal that experience plays a major role, in that professionals who are not required to authenticate records in the course of their work tend to have more confidence in technical mechanisms that those who are. The study concludes that most records professionals ensure authenticity by relying on social mechanisms but have greater confidence in technical mechanisms to authenticate records and data. In other words, records professionals, traditionally the trusted agents of record control (trustees), have frequently become the trustors, placing their trust in technology of which they may have little understanding and even less control.Arts, Faculty of

This interface is programmed from a computer to assign individual tags to each one of the display channels. This system eliminates DAC's and patch panels. It simplifies display system operation, speeds up transition from test to test and reduces maintenance costs.

With the rapid development of power systems, more and more smart devices are installed in power industries, and each of them is gathering tons of information every day.Due to the data explosion and the difficulty of processing these data, data visualization, a big data technology, has become a trend. With the help of information technology, the visualization of real-time data has been achieved in power industries and there are multiple successful examples such as one-line diagram, load flow dashboard and equipment dashboard.In fault analysis group, digital fault recorders are essential to record and report an event.They are triggered when a fault occurs and corresponding report is generated instantly.However, people seldom utilize the historical data from DFRs to analyze the power quality issues.Therefore, this thesis presents the development of a power quality dashboard by using the collected data from DFRs.Three related power quality analyses have been accomplished in this paper: voltage and current variation, harmonics and unbalance components.Recursive algorithm is applied to compute the phasors and errors; Discrete Fourier Transform is utilized to extract harmonics from the samples; and the symmetric components are calculated by "A"-matrix transformation.The start page for the dashboard is a google map with all the DFR markers, and after double-clicking the marker, the report page will be opened.With the reports, engineers can not only monitor the event but also analyze out the possible causes and characteristics for a fault.For those renewable energy substation, the harmonic contents can be supervised so that the damages and losses can be significantly reduced by identifying the high harmonics.Ultimately, the goal of the dashboard is to achieve warning status and harmonic gradient mapping in the future.Master of Science

But because of the completely different writing method and technology employed, it is difficult to make completely analogous performance comparisons between analog and digital chart recorders. This has led to some confusion when replacing aging stylus recorders is contemplated. Objectives: Establish a set of universal, standardized performance characteristics for digital chart recorders. Introduce appropriate terminology, allowing valid, repeatable comparison of old and new systems.

This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability. It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed. It is necessary to weigh the importance of integrity and long-term usability against the costs of preserving documents in multiple formats. This is a two years master's thesis in Archival Science, Library and Museum studies.

Full textAbstract:
The current state of international civilian (General Aviation) helicopter flight safety was perceived to be poor and without focus on the potential application of low-cost digital data acquisition devices to increase the quantity of flight data available for analysis, which could help identify issues leading to common incident and accident scenarios. The research project undertook a review of some of the common incident and accident scenarios, performed an analysis of the composition of the worldwide helicopter fleet and explored the interaction of operators, pilots, missions, and national aviation authorities, in order to understand and define the context for this study. Two radically different types of digital flight and event data recorders were then developed, which were considered appropriate for use in the most common small to medium sized helicopter types identified, in order to determine if reliable low-cost digital data acquisition was achievable. Also developed were software tools for extracting the recorded data sets and their processing/analysis. The proof of concept devices were flight tested, in a variety of environments by a number of helicopter operators and manufacturers in Europe and North America, in order to determine whether such simple devices actually returned useful flight data and in doing so contribute to improving flight safety by highlighting the occurrence of common issues. During the flight trials a number of real safety critical events were captured or observed, despite being flown for only a fraction of the time that would statistically elapse between incidents. Examination of the data sets revealed an abundance of information about pilot behaviour, which it will be argued substantiates the widely held belief that most accidents are caused by pilot error or negligence. It will be asserted that these results demonstrate that real improvements in training and flight safety can be achieved through the wide spread use of such proof of concept devices and their associated software tools. The international helicopter community has subsequently expressed a strong desire for such devices to become common place in small to medium sized helicopters.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, NevadaA need has been identified in the Test and Evaluation (T&E) and tactical aircraft communities for a ruggedized high-speed instrumentation data recorder to complement the ever-increasing number of high frame-rate digital cameras and sensors. High-speed digital camera manufacturers are entering this market in order to provide adequate recording capability for their own cameras. This paper discusses a Solid-State Data Recorder (SSDR) for use in Imaging and High-Speed Sensor Data Aquisition applications. The SSDR is capable of a 10.4 Gb/sec sustained, 16Gb/sec burst, input data rate via a proprietary 32-channel-by-10-bit generic high-speed parallel interface, a massively-parallel 256-bit bus architecture, and unique memory packaging design. A 32-bit PCIbus control/archive and dedicated DCRsi™ interface are also employed, allowing data archiving to standard high-speed interfaces (SCSI, Fiber-Channel, USB, etc.) and DCRsi™-compatible tape recorders.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, CaliforniaThe transition of PCM recording from analog to digital recorders was completed at many test ranges more than a decade ago as marked by delivery of data on S-VHS tape, CD-ROM, DVD, ZIP disc, JAZ disc, 8mm tape and DLT tape for low rate data and D-1 cassettes for high rate data. Data then quickly began distribution via the internet and other networks. Analog recorders have remained a necessary legacy for the long transition to convert from analog to digital (PCM) data transmission from the test vehicles. However, the new digital recorder capabilities have removed this requirement to convert the transmissions from the test vehicle. Analog signal and predetection recording on digital recorders has been successfully demonstrated at costs below the existing analog recorders. Application of new techniques in a methodical transition program to the new digital recorders has proven the many benefits of recording wider bandwidths with excellent repeatability. Repeatability issues are primarily in the very low error sources of the processing system because the major analog error sources of the analog tape recorders, analog time code readers, analog demodulators, etc have been greatly reduced. This paper provides test results of recording higher signal rates and bandwidths of the new programs and describes the techniques and implementation through procedures of the Western Range transition from analog to digital recorders. Surprising results show predetection and analog signal recording costs are nearly the same as PCM recording costs due to the price of deliverable media with respect to mission recording requirements.
