  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sara Muminovic; Christina Lindén; [2023]
    Keywords : Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Abstract : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. READ MORE

  3. 2. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rishabh Raj; [2022]
    Keywords : Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

    Abstract : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. READ MORE

  4. 3. Diffusion-Based MR Methods for Measuring Water Exchange

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Shan Cai; [2022]
    Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

    Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE

  5. 4. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jakob Andrén; [2021]
    Keywords : hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Abstract : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. READ MORE

  6. 5. Permeability of temporary restorative materials exposed to underwater pressure

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Elias Sjöberg; Daniel Hallin; [2020]
    Keywords : dental leakage; dental restoration; dental restoration temporary; diving; pressure; naval medicine;

    Abstract : Området submarin miljö och dentala förhållanden finns det få studier inom. Detta ger behandlare svårigheter att ta evidensbaserade behandlingsbeslut för grupper som utsätts för hyperbariskt tryck. För att kunna föra fram kvalitativa studier och odontologisk kunskap krävs tillförlitliga metoder. READ MORE
