  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  3. 2. Att likvidera reglerna omtvångslikvidation av aktiebolag vid kapitalbrist : En rättsanalys av förslaget i SOU 2023:34 om att ersätta tvångslikvidationsreglerna med solvensbaserade regler, i syfte att ge ett mer ändamålsenligt skydd

    Uppsats för yrkesexamina på avancerad nivå, Stockholms universitet/Juridiska institutionen

    Författare :Adam Wramberg; [2024]
    Nyckelord :Examensuppsats; Juridik; Bolagsrätt; Aktiebolag; Kapitalbrist; Tvångslikvidation; Medansvar;

    Sammanfattning : The Swedish legislation regarding culpulsory liquidation and personal liability has been heavily criticized. In the beginning of July 2023, a proposal was published from an inquiry regarding how to prevent and counter criminal and dishonest use of corporations. LÄS MER

  4. 3. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

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

    Författare :Therese Bäckström; [2023]
    Nyckelord :Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

    Sammanfattning : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. LÄS MER

  5. 4. Jämförelse mellan platsgjuten och prefabricerad betongbyggnad i RFEM

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Andjela Janjic; Vanessa Bilic; [2023]
    Nyckelord :;

    Sammanfattning : The choice of buidling materials and the decisions that are made early on in the construction phasehave a great effect on the outcome of the project. Just like building materials, modeling is animportant part of every project and this degree project combines modeling with choosing buildingmaterials in order to compare two concrete buildings in a program called RFEM.

  7. 5. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Natachai Terawatsakul; [2023]
    Nyckelord :;

    Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER
