  1. 21. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :John Alanko Öberg; Carl Svensson; [2023]
    Nyckelord :Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Sammanfattning : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. LÄS MER

  3. 22. Hydrogen Pipeline Infrastructure Design for Germany in 2045

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Flora Marianne von Mikulicz-Radecki; [2023]
    Nyckelord :Hydrogen Transport Infrastructure; Pipeline Networks; Retrofitting; Infrastructure Planning; Peak Hour Hydrogen Demand; Utilization Rate; Costs of Avoided Emissions; Carbon Neutrality; Infrastruktur för vätgastransport; rörledningsnät; eftermontering; infrastrukturplanering; efterfrågan på vätgas under m;

    Sammanfattning : Germany’s commitment to carbon neutrality by 2045 underscores the need for climate action, with hydrogen’s multiple uses in industry, transport, and energy offering a viable solution. Efficient retrofitting of the extensive natural gas pipeline network can enable hydrogen to be transported from supply to demand centers. LÄS MER

  4. 23. Big Data and Analytics with Driving  Data : Implementation and Analysis of Data Pipeline and Data Processing Resources

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Ivar Blohm; Erik Jarvis; [2023]
    Nyckelord :;

    Sammanfattning : This thesis project was conducted in cooperation with Zenseact for the purpose of investigating the possible usage of Google BigQuery and its capabilities to store and provide insights of large time-series data. An end-to-end data pipeline was built to facilitate the movement of data from Zenseact's local servers and ingestion into BigQuery. LÄS MER

  5. 24. Exploring the potential of low-cost sensors in the production stage of the construction industry

    Master-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Aiswarya Udayakumar; Aswathi Sarkara Sidharthan; [2023]
    Nyckelord :low-cost sensors; temperature; humidity; construction industry;

    Sammanfattning : The construction industry is massive but not so advanced in adapting and utilizing technology. Sensors and sensing technology are critical elements that can enhance the digitalization of the construction industry. The need for low-cost sensors is rapidly increasing as the industry steps into the construction 4.0 phase. LÄS MER

  7. 25. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Melker Axelsson; [2023]
    Nyckelord :catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER
