  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

    Sammanfattning : The Internet of things (IoT) device has been widely used in various fields, and its market is expanding rapidly. However, the growing usage of IoT devices also brings more security concerns. The smart door lock is one of the smart home IoT devices that need to be designed securely. LÄS MER

  4. 3. Protecting software in embedded IoT units : The impact of code obfuscation

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

    Författare :Fredrik Karlsson; [2023]
    Nyckelord :Embedded; Obfuscation; Software protection; Internet of Things; Inbyggd; Obfuskering; Mjukvaruskydd; Internet of Things;

    Sammanfattning : Embedded Internet of Things (IoT) products are taking up a larger part of the market thanks to smaller, cheaper and more advanced components. For companies that spend time and resources on developing software for these products, it is important to keep that software secure to maintain the advantage gained. LÄS MER

  5. 4. Decompiling Go : Using metadata to improve decompilation readability

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

    Författare :Mattias Grenfeldt; [2023]
    Nyckelord :Decompilation; Go; Runtime Metadata; Reverse Engineering; Dekompilering; Go; Körtidsmetadata; Reverse Engineering;

    Sammanfattning : Malware written in Go is on the rise, and yet, tools for investigating Go programs, such as decompilers, are limited. A decompiler takes a compiled binary and tries to recover its source code. Go is a high-level language that requires runtime metadata to implement many of its features, such as garbage collection and polymorphism. LÄS MER

  7. 5. Accounting for the Measurement Bias: A Study of Market Efficiency in the United States and the Relevance of Extensive Fundamental Analysis in Equity Valuation

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Erik Bergmark; Hugo Freudenthal; [2023]
    Nyckelord :Accounting valuation bias; Fundamental analysis; Horizon Value; Market mispricing; Residual income valuation;

    Sammanfattning : This thesis investigates abnormal returns over the period 1983-2021 from an investment strategy that is based on public accounting information. Investment positions are taken in US manufacturing firms and are held for 36 months using a self-financing (hedged) portfolio. LÄS MER
