  1. 1. Designing a Cost Effective Encoder for High Performance Doors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Emanuel Edelstam; David Petersson; [2023]
    Nyckelord :Encoder; High speed doors; Motor; Product development; Prototyping; ASSA ABLOY; Technology and Engineering;

    Sammanfattning : Målet med detta arbete var att utveckla en prototyp av en kostnadseffektiv pulsgivare till motorerna för ASSA ABLOYs snabbrullduksportar. Pulsgivaren ger återkoppling till de automatiska dörrarnas kontrollsystem och ska göra detta på ett tillförlitligt sätt samtidigt som de ska vara mer kostnadseffektiva än de nuvarande lösningarna som används på ASSA ABLOY.

  3. 2. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Adnan Asif Rifat; [2023]
    Nyckelord :Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Sammanfattning : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. LÄS MER

  4. 3. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :David Llorens Rauret; [2022]
    Nyckelord :Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Sammanfattning : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. LÄS MER

  5. 4. Swedish Corporate Ownership and Choice of Debt: The Effect of Dual Class Shares

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi; Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Gustav Ossmark; Edvin Sveder; [2022]
    Nyckelord :Dual class shares; Bank Debt; Public Debt; Excess control rights;

    Sammanfattning : Using yearly ownership and capital structure data, we estimate control-ownership divergence, due to dual class shares, in the Swedish stock market 2011-2020. We investigate its effect on the firm's choice of debt and debt-to-equity ratio through multivariate regression analysis. LÄS MER

  7. 5. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Linda Péroux; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. LÄS MER
