    Sammanfattning : Mobila hydrauliska ventiler används ofta i tunga industrier för att styra hydrauliska system för att hantera material. Funktionaliteten är kritisk i dessa situationer då det utgör en miljöfara och säkerhetsfara om funktionaliteten inte är uppnådd. LÄS MER

  3. 2. Realizing a screwdriving operation for human-robot collaboration : During the assembly of a truck engine valve-hood

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Arturo Mateos Rodríguez; [2021]
    Nyckelord :;

    Sammanfattning : According to Folgiatto, da Silveira and Borenstein (2012), the current trend in the industry indicates a change from a mass production to a mass customization manufacturing. This mass customization means an increase on the need of flexibility, as the production line must be ready for frequent changes in order to adapt for producing different product variants. LÄS MER

  4. 3. Trendning och tillståndsövervakning av ventilmanöverdon i säkerhetssystem på Forsmark 1 och 2

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Egil Schultz; [2020]
    Nyckelord :;

    Sammanfattning : Nuclear power is one of the main players in the Swedish energy system with close to40% of the electricity production. As nuclear power needs to have a well- functioningsafety system for cooling the reactor and prevent contamination in case of anaccident, the components of this system must be maintained in a functioningcondition.

  5. 4. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Eimantas Gladkauskas; [2019]
    Nyckelord :Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Sammanfattning : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  7. 5. Improved control strategies for primary frequency control in Swedish combined heat and power plants

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Gustav Sondell; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to previous simulations done by Solvina. LÄS MER
