  1. 6. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Ellen Ek Moreau; [2023]
    Nyckelord :Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Sammanfattning : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  3. 7. Validation of Finite Element Model of a Tetra Pak Package

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Nyckelord :Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Sammanfattning : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  4. 8. Application of electrodes with redox mechanisms for the desalination of water

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

    Författare :Pablo Moreno Cerezo; [2023]
    Nyckelord :Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

    Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER

  5. 9. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs

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

    Författare :Elochukwu Mbah; [2023]
    Nyckelord :Silicon Carbide Power MOSFET; Gate Inductance; Gate Resistance; Miller Period; dv dt and di dt transients; Double Pulse Test; Kiselkarbid Power MOSFET; Gateinduktans; Gate Resistance; Millerperioden; dv dt och di dt transienter; Dubbelpulstest.;

    Sammanfattning : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. LÄS MER

  7. 10. Modeling for characterization of continuous casting simulator using CFD

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

    Författare :Filip Reineholm-Hult; [2023]
    Nyckelord :Continuous casting; CFD; computational fluid dynamics;

    Sammanfattning : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. LÄS MER
