  1. 21. Modelling of nanometric cutting in metals using MD simulations

    Magister-uppsats, Lunds universitet/Mekanik

    Författare :Damien Gautier; [2022]
    Nyckelord :Nanometric cutting; Molecular Dynamics; Technology and Engineering;

    Sammanfattning : This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. LÄS MER

  3. 22. Reduction of Noise and Artefacts in MRIScan of Metal Implant Reconstructed by Frequency Mapping

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Pontus Wahlqvist; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Metal objects can cause significant artefacts in magnetic resonance imaging (MRI) scans, cause loss of signal and what is known as geometric warping. There are ways to address these problems using different MRI sequences. This project looks at a newer method of artefact correction proposed by Månsson and Morin. LÄS MER

  4. 23. Metal-Organic Frameworks for Carbon Dioxide Capture : Using Sustainable Synthesis Routes

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Dhruva Deole; [2022]
    Nyckelord :Metal-Organic Frameworks; Metal-Organic Frameworks for Carbon Dioxide Capture; Sustainable Synthesis; 3D Printing of Metal-Organic Frameworks; Nanomaterials; Nanoporous Materials; Nanotechnology and Functional Materials;

    Sammanfattning : Globally the combustion of fossil fuels has increased to a greater extent. Carbon dioxide (CO2) a major greenhouse gas isa by-product of such combustion practices. LÄS MER

  5. 24. Active Learning for Solving Expensive Optimization Problems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Siwei Fu; [2022]
    Nyckelord :;

    Sammanfattning : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. LÄS MER

  7. 25. Modelling an air handling unit, building and occupant, regarding energy, moisture and frost protection

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Marius Daugela; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Frost formation in heat exchangers is an often accruing issue in cold climates. The aim of the project is to calculate the risk of frost formation in different Swedish cities by modeling vapor and frost behavior in heat exchangers... LÄS MER
