  1. 21. Forced response numerical investigation of a transonic compressor rotor

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

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  3. 22. Self-Supervised Fine-Tuning of sentence embedding models using a Smooth Inverse Frequency model : Automatic creation of labels with Smooth Inverse Frequency model

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Vittorio Pellegrini; [2023]
    Keywords : Natural Language Processing; sentence embeddings; Transformer-based architectures; sentence paraphrasing; sentence similarity; sentence clustering; Naturlig språkbehandling; inbäddning av meningar; transformatorbaserade arkitekturer; parafrasering av meningar; meningslikhet; klustring av meningar Canvas Lärplattform; Dockerbehållare; Prestandajustering;

    Abstract : Sentence embedding models play a key role in the field of Natural Language Processing. They can be exploited for the resolution of several tasks like sentence paraphrasing, sentence similarity, and sentence clustering. READ MORE

  4. 23. Tug-of-War and the p-Laplace Equation : Exploring a Mathematical link between Game Theory and Nonlinear Elliptic PDE's

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Zackarias Chronéer; [2023]
    Keywords : p-Laplacian; tug-of-war;

    Abstract : In this report the connection between p-harmonic functions and the tug-of-war game is presented and some applications are mentioned. Moreover, sufficient background information of solutions to the p-Laplace equation is given. And to finish, an example of the game is given with simulations. . READ MORE

  5. 24. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Viktor Svensson; Robin Raymundsson; [2023]
    Keywords : Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Abstract : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. READ MORE

  6. 25. Beyond the Gross-Pitaevskii Equation: A Perturbative Approach

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teknisk fysik (CI)

    Author : Anton Johansson; [2023]
    Keywords : Gross-Pitaevskii; Beyond mean-field; Many-body Perturbation Theory; Bose-Einstein Condensate; BEC; Physics and Astronomy;

    Abstract : We propose and implement a beyond Gross-Pitaevskii approach based on Many-Body Perturbation theory (MBPT) for the study of Bose-Einstein Condensate (BECs) ground states. Two partitions of the system Hamiltonian are considered. READ MORE
