  1. 1. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :David Wedin; [2024]
    Nyckelord :Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

    Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER

  3. 2. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Carl Pontén; [2024]
    Nyckelord :Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

    Sammanfattning : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

  4. 3. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

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

    Författare :Reman Soryani; [2023]
    Nyckelord :Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER

  5. 4. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Arvid Söderlund; [2023]
    Nyckelord :Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Sammanfattning : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  7. 5. Undersökning om applicerbarhet av Module Type Package för bioprocess-system designade på Cytiva

    Kandidat-uppsats, Högskolan i Gävle/Elektronik

    Författare :Hannes Estebring; [2023]
    Nyckelord :Module Type Package; MTP; NAMUR och VDI VDE;

    Sammanfattning : PLC-system har funnits ute i industrin sedan sent 1970-tal och appliceras på miljontals olika processer. Företag inom processindustrin står idag inför stora utmaningar då en instabil marknad ställer krav på en mer hållbar och flexibel infrastruktur. LÄS MER
