  1. 1. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    Master-uppsats, Karlstads universitet

    Författare :Marcus Roseen; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. LÄS MER

  3. 2. “It was a free and healthy job” : timber floating on the river Ångermanälven in the 20th century

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Olivia Forssén; [2023]
    Nyckelord :timber floating; forest history; women in timber floating; interviews; historical records;

    Sammanfattning : The exploitation of northern Sweden's forests began in about the 1830s and continued expanding northwards over the following decades. A key factor that enabling the exploitation of these forests was the natural infrastructure, such as the network of rivers, creeks and flooding during the summer, which made it possible to float timber from the forests to the sawmills on the coast.

  4. 3. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

    Master-uppsats, KTH/Kemiteknik

    Författare :Josefin Strandberg; [2023]
    Nyckelord :Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

    Sammanfattning : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. LÄS MER

  5. 4. Development of a Closed-loop for Measuring and Stimulating Peripheral Nervous System

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Diego Ignacio Roy Hierro; [2022]
    Nyckelord :Control; Close-loop; PNI; VNS; HRV; Stimulation Protocol; Kontroll; Close-loop; PNI; VNS; HRV; Stimuleringsprotokoll.;

    Sammanfattning : Bioelectronic medicine is an emerging discipline being a intersection of neu- roscience, immunology and electrical engineering. Chronic inflammation is linked to disorders such as diabetes, rheumatoid arthritis, asthma, atheroscle- rosis, obesity and inflammatory bowel disease. LÄS MER

  7. 5. Self-Learning Methodology for Failure Detection in an Oil- Hydraulic Press : Predictive maintenance

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Diego Alonso Guillen Rosaperez; [2020]
    Nyckelord :Signal Processing; Deep Learning; Machine Learning; Predictive Maintenance; Anomaly Detection.; Signalbehandling; djupinlärning; maskininlärning; förutsägbart underhåll; upptäckt av avvikelser.;

    Sammanfattning : Deep Learning methods have dramatically improved the state-of-the-art across multiple fields, such as speech recognition, object detection, among others. Nevertheless, its application on signal processing, where data is frequently unlabelled, has received relatively little attention. LÄS MER
