  1. 1. Metaller i Vombsjön - Mygglarver som bioindikator för miljöövervakning

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Siri Bengtsson; [2024]
    Nyckelord :Bioindicators; Chironomidae; Freshwater source; Lake Vomb; Metal concentrations; Pollution; Sediment sampling; Earth and Environmental Sciences;

    Sammanfattning : This study investigates concentrations of eight metals (Cu, Zn, Cd, Pb, Hg, Cr, Ni, As) in the freshwater resource Lake Vomb, located in the south of Sweden (Scania), and explores the potential use of deformed Chironomidae larvae as bioindicator. Sediment samples from six locations were analysed against threshold values from the Swedish Agency for Marine and Water Management and background values from the Swedish Environmental Protection Agency.

  3. 2. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Alfredo Bici; [2023]
    Nyckelord :;

    Sammanfattning : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. LÄS MER

  4. 3. Utdragshållfasthet och styvhet i axiellt belastade skruvinfästningar i korslaminerat trä

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Carl Hagvall; Svante Wallin; [2023]
    Nyckelord :KL-trä; skruvförband; skruvinfästningar; styvhet; utdragshållfasthet; utdragsprov;

    Sammanfattning : Introduction – Cross-laminated timber (CLT) is a product that is becoming increasingly common in the construction industry. CLT is categorized as homogeneous or combined, where homogeneous has the same strength classes throughout the entire cross-section and combined has varying strength classes across the cross-section.

  5. 4. Fracture simulation with a hyperelastic phase field model

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Adrien Fradet; [2023]
    Nyckelord :Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Sammanfattning : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

  7. 5. 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.
