  1. 11. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malte Petersson; [2022]
    Keywords : Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

    Abstract : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. READ MORE

  3. 12. Dimensionality Reduction in High-Dimensional Profile Analysis Using Scores

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Jonathan Vikbladh; [2022]
    Keywords : High-dimensional data; Hypothesis testing; LR test; Linear scores; Multivariate analysis; Profile analysis; Spherical distributions;

    Abstract : Profile analysis is a multivariate statistical method for comparing the mean vectors for different groups. It consists of three tests, they are the tests for parallelism, level and flatness. The results from each test give information about the behaviour of the groups and the variables in the groups.

  4. 13. Organization of Electronic Dance Music by Dimensionality Reduction

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Victor Tideman; [2022]
    Keywords : Dimensionality Reduction; Digital Signal Processing; Similarity; Music;

    Abstract : This thesis aims to produce a similarity metric for tracks of the genre: Electronic Dance Music, by taking a high-dimensional data representation of each track and then project it to a low-dimensional embedded space (2D and 3D) by applying two Dimensionality Reduction (DR) techniques called t-distributed stochastic neighbor embedding (t-SNE) and Pairwise Controlled Manifold Approximation (PaCMAP). A content-based approach is taken to identify similarity, which is defined as the distances between points in the embedded space. READ MORE

  5. 14. CFD validation of a new gas turbinestage design with experimental data

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Claudia Florentina Balan; [2022]
    Keywords : ;

    Abstract : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.

  6. 15. Reduction of Noise and Artefacts in MRIScan of Metal Implant Reconstructed by Frequency Mapping

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Pontus Wahlqvist; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE
