  1. 16. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

    University essay from KTH/Elkraftteknik

    Author : Patrik Brauer; [2018]
    Keywords : Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

    Abstract : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. READ MORE

  3. 17. Proteinbaserat material för livsmedelsförpackningar : med fokus på mjölkproteiner

    University essay from SLU/Department of Molecular Sciences

    Author : Gabriella Apelthun; [2018]
    Keywords : Protein; whey; casein; edible films; food packaging; material;

    Abstract : Livsmedelsförpackningar är ett område som har stor utvecklingspotential eftersom både konsumtionen och produktionen av plast har ökat sedan 50-talet. Trots att vi vet att konventionella plastmaterial framställs av råmaterialet petroleum, en icke förnybar och uttömbar källa. Förpackningsindustrin står för den största andelen plast. READ MORE

  4. 18. Fines Content and Density Effects on Tailings Behaviour : A Laboratory Study on Geotechnical Properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Viktor Wiklund; [2018]
    Keywords : strength; compressibility; permeability; anrikningssand; hållfasthet; konsolidering; permeabilitet;

    Abstract : Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. READ MORE

  5. 19. Kolhydratdigestion hos häst : icke-strukturella kolhydrater

    Abstract : Hästar utfodras i dagsläget på ett sätt som inte är anpassat efter deras digestionsapparat. Det kan leda till sjukdomar såsom kolik, fång och magsår. De här sjukdomarna är vanligt förekommande och kan i vissa fall vara fatala. READ MORE

  6. 20. A Water Resistant Film Forming Emulsion - The First Steps towards a Topical Preventive Product against Intertriginous Dermatitis

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ida Moen Larsson; [2017]
    Keywords : pharmaceutical technology; läkemedelsteknologi; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Abstract : Intertriginous dermatitis (Intertrigo) is a skin disease caused by friction between adjacent skin surfaces. Heat and moisture induces an inflammation, causing pain and often secondary infections. The aim of this degree project was to develop a prototype for a topical film forming emulsion for patients suffering from Intertrigo. READ MORE
