  • Why ODF?” - the Importance of Opendocument Format for Governments
    “Why ODF?” - The Importance of OpenDocument Format for Governments Documents are the life blood of modern governments and their citizens. Governments use documents to capture knowledge, store critical information, coordinate activities, measure results, and communicate across departments and with businesses and citizens. Increasingly documents are moving from paper to electronic form. To adapt to ever-changing technology and business processes, governments need assurance that they can access, retrieve and use critical records, now and in the future. OpenDocument Format (ODF) addresses these issues by standardizing file formats to give governments true control over their documents. Governments using applications that support ODF gain increased efficiencies, more flexibility and greater technology choice, leading to enhanced capability to communicate with and serve the public. ODF is the ISO Approved International Open Standard for File Formats ODF is the only open standard for office applications, and it is completely vendor neutral. Developed through a transparent, multi-vendor/multi-stakeholder process at OASIS (Organization for the Advancement of Structured Information Standards), it is an open, XML- based document file format for displaying, storing and editing office documents, such as spreadsheets, charts, and presentations. It is available for implementation and use free from any licensing, royalty payments, or other restrictions. In May 2006, it was approved unanimously as an International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) standard. Governments and Businesses are Embracing ODF The promotion and usage of ODF is growing rapidly, demonstrating the global need for control and choice in document applications. For example, many enlightened governments across the globe are making policy decisions to move to ODF.

    17 TV- und Filmbeiträge insgesamt. Phase I: 1956 – 1961 3 Politmagazine | 1 Nachrichten ● Die rote Optik (1959) ● Der schwarze Kanal ● Panorama ● SFB-Abendschau (alle 13. August 1961) Politische TV-Magazine stehen im Mittelpunkt dieser zeitlichen Anfangsphase beider deutscher Staaten. Am Beispiel von drei Politmagazinen und einer Nachrichtensendung betrachten wir die Berichterstattung von jenem Tag, der Berlin und Deutschland in zwei Teile trennte. Der 13. August 1961 aus Sicht von Ost und West – Ein Meilenstein der Geschichte. Phase II: 1962 – 1976 3 Filme | Fiktion ● Polizeiruf (1972) ● Blaulicht (1965) – Die fünfte Kolonne (1976) In den 70er Jahren setzte man verstärkt auf Unterhaltungssendungen, in Ost wie West. Eine besondere Rolle spielte dabei die Entwicklung des „Tatort“ (BRD) und des „Polizeiruf“ (DDR), den die DDR als Gegenstück zum westdeutschen Krimi-Format einsetzte. Besonders brisant: Im allerersten „Tatort – Taxi nach Leipzig“ wurde ausgerechnet ein DDR-Schauplatz in Szene gesetzt. Bei „Blaulicht“ und „Die fünfte Kolonne“ bezichtigen sich Ost und West gegenseitig der Spionage. – Spannende Gegensätze in der TV-Unterhaltung.

  • Clarifying the Legacy Data Conversion Plan & Introducing The
    PharmaSUG 2017 - Paper SS11 Documenting Traceability for the FDA: Clarifying the Legacy Data Conversion Plan & Introducing the Study Data Traceability Guide David C. Izard, Chiltern International Ltd. Kristin C. Kelly, Merck & Co. Inc. Jane A. Lozano, Eli Lilly & Company ABSTRACT Traceability from data collection through to the presentation of analysis results has always been a concern of the US Food & Drug Administration (FDA). The introduction of electronic data as part of submission added additional steps to confirm provenance of information. Now the requirement to provide clinical and non-clinical data based on a set of FDA endorsed data standards adds exponentially to the challenge, especially if legacy format data structures were utilized when the study was originally executed and reported but data meeting FDA requirements must be present in your submission. The PhUSE organization, made up of volunteers across industry, has worked closely with the FDA to develop tools to support the organization, presentation and interpretation of clinical and non-clinical data to regulatory bodies. Examples include the Study & Analysis Data Reviewer's Guides and the Study Data Standardization Plan. These documents describe routine situations where FDA endorsed data standards are deployed at the time a study is initiated; additional support is needed when the provenance of the data is not as straightforward. The FDA's Study Data Technical Conformance Guide calls out for the need to provide a Legacy Data Conversion Plan & Report when legacy data is the source of deliverables based on FDA endorsed data standards, but it is not very clear as to when you must provide one.

Institute of Technology, B.G.Nagar, Mandya-571448 Assistant Professor ,Department of ECE, B.G.S. Institute of Technology, B.G.Nagar, Mandya-571448 ---------------------------------------------------------ABSTRACT----------------------------------------------------------- Internet-based voice transmission, digital telephony, intercoms, telephone answering machines, and mass storage, we need to compress audio signals. ADPCM is one of the techniques to reduce the bandwidth in voice communication. More frequently, the smaller file sizes of compressed but lossy formats are used to store and transfer audio. Their small file sizes allow faster Internet transmission, as well as lower consumption of space on memory media. However, lossy formats trade off smaller file size against loss of audio quality, as all such compression algorithms compromise available signal detail. This paper discusses the implementation of ADPCM algorithm for audio compression of .wav file. It yields a compressed file ¼ of the size of the original file. The sound quality of the audio file is maintained reasonably after compression. KEYWORDS: ADPCM, audio compression. --------------------------------------------------------------------------------------------------------------------------------------

  • The Development of Algorithms for On-Demand Map Editing for Internet and Mobile Users with Gml and Svg
    THE DEVELOPMENT OF ALGORITHMS FOR ON-DEMAND MAP EDITING FOR INTERNET AND MOBILE USERS WITH GML AND SVG Miss. Ida K.L CHEUNG a, , Mr. Geoffrey Y.K. SHEA b a Department of Land Surveying & Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong, email: [email protected] b Department of Land Surveying & Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong, email: [email protected] Commission VI, PS WG IV/2 KEY WORDS: Spatial Information Sciences, GIS, Research, Internet, Interoperability ABSTRACT: The widespread availability of the World Wide Web has led to a rapid increase in the amount of data accessing, sharing and disseminating that gives the opportunities for delivering maps over the Internet as well as small mobile devices. In GIS industry, many vendors or companies have produced their own web map products which have their own version, data model and proprietary data formats without standardization. Such problem has long been an issue. Therefore, Geographic Markup Language (GML) was designed to provide solutions. GML is an XML grammar written in XML Schema for the modelling, transport, and storage of geographic information including both spatial and non-spatial properties of geographic features. GML is developed by Open GIS Consortium in order to promote spatial data interoperability and open standard. Since GML is still a newly developed standard, this promising research field provides a standardized method to integrate web-based mapping information in terms of data modelling, spatial data representation mechanism and graphic presentation. As GML is not for data display, SVG is an ideal vector graphic for displaying geographic data.

All resources, sources, and literature, which I used in preparing or I drew on them, I quote in the thesis properly with stating the full reference to the source. 3 Acknowledgement I would like to thank my advisor, RNDr. Václav Lorenc, for his guidance and advice during my work on this thesis. 4 Abstract The goal of this thesis is to provide an in-depth assessment of the use of PDF (Portable Document Format) file format as an attack vector and the current state of the field of malicious document analysis. First, we provide detailed introduction into the inner organization and structure of PDF files and describe how different features can be used for obfuscation purposes. Next, we survey available options for viewing PDF documents in web browser environment, as well as tools for PDF document analysis. The practical part consists of designing and implementing a web application that serves as framework for malicious document analysis.
