  1. 1. The use of higher steel grades in building elements

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Hampus Berggren; [2021]
    Nyckelord :Area reduction; Change of steel grade; Emission reduction; High strength steel; Higher steel grade; Steel;

    Sammanfattning : Structural steel is one of the main building materials used commercial. Its strength is its formality and high yield strength which allows less material overall. Steel is often divided into steel grades such as S275, S355, S420 and so forth. LÄS MER

  2. 2. Improving Biometric Log Detection with Partitioning and Filtering of the Search Space

    Magister-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Nijat Rajabli; [2021]
    Nyckelord :tree log tracking; tree log identification; cross-section segmentation; search space reduction; transfer learning;

    Sammanfattning : Tracking of tree logs from a harvesting site to its processing site is a legal requirement for timber-based industries for social and economic reasons. Biometric tree log detection systems use images of the tree logs to track the logs by checking whether a given log image matches any of the logs registered in the system. LÄS MER

  3. 3. A novel and feasible material recycling technique for end-of-life textiles as All-Cellulose Composites (ACCs)

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Belinda Johansson; [2021]
    Nyckelord :all-cellulose composites; end-of-life textiles; denim fabrics; ionic liquid; mechanical properties; sustainability;

    Sammanfattning : Today’s consumption of textiles generates a large volume of textile waste. Therefore, it is needed to find solutions to re-use the textile waste rather recycling fibers into new fibers. Research using pre- and post-consumer textiles in composites is ongoing and an interesting direction. LÄS MER

  4. 4. Validation of the Westinghouse BWR nodal core simulator POLCA8 against Serpent2 reference results

    Master-uppsats, KTH/Fysik

    Författare :Mathilde Gaillard; [2021]
    Nyckelord :Nodal Core Analysis; Monte Carlo Methods; CBH Effects; Nodal kärnanalys; Monte Carlo-metoder; CBH-effekter;

    Sammanfattning : When a new nodal core simulator is developed, like all other simulators, it must go through an extensive verification and validation effort where, in the first stage, it will be tested against appropriate reference tools in various theoretical benchmark problems. The series of tests consist of comparing several geometries, from the simplest to the most complex, by simulating them with the nodal core simulator developed and with some higher order solver representing the reference solution, in this case on the Serpent2 Monte Carlo transport code.

  5. 5. Numerisk modellering av deformationer och portryck i en experimentdamm : Jämförelse mellan in-situmätningar och FE-simuleringar i PLAXIS 2D

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Adam Sjödin; [2021]
    Nyckelord :Fully-coupled flow deformation; Embankment dam; Hardening Soil; Unsaturated conditions; Optimisation; PLAXIS; SoilTest; Triaxial test; van Genuchten; Soil-water characteristic curve; Soil-water retention curve; Saturation; Flödes-deformationsanalys; Fyllningsdamm; Hardening Soil; Omättade förhållanden; Optimering; PLAXIS; SoilTest; Triaxialförsök; van Genuchten; Vattenbindningskurva; Vattenmättnad;

    Sammanfattning : Under hösten 2019 har Vattenfall Research & Development byggt en experimentell jordfyllningsdamm i Älvkarleby med dimensionerna 20x15x4 meter. Delar av experimentdammen är konventionellt konstruerade och har installerats med geoteknisk utrustning som utgörs av bland annat inklinometrar och portrycksgivare. LÄS MER
