  1. 16. Investigation of torsion modes in overhead traveling cranes: : Reviewing the ISO 22980 standard

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Simon Jens; [2023]
    Nyckelord :Overhead traveling crane; Finite element method; Frequency and experimental vibration analysis; Travers; finita elementmetod; egenfrekvensanalys; experimentell vibrationsanalys;

    Sammanfattning : Overhead cranes and rail mountings in the wall are subjected to vibrations whenlifting equipment. The purpose of this thesis is to review if the minimum frequencyvalue for cranes, according to the ISO 22986:2007 standard is conservative whendesigning overhead traveling cranes. LÄS MER

  3. 17. Bilden i betraktarnas ögon : En intervjustudie om betraktarnas upplevelse av bildkonst

    Kandidat-uppsats, Uppsala universitet/Konstvetenskapliga institutionen

    Författare :Per Skude; [2023]
    Nyckelord :Art beholder; Art experience; Everyday art experience; Psychology and perception in art experience; Qualitative research interview; Reader - response theory; Reception aesthetics; Similarities of beholders experience and artist intention.;

    Sammanfattning : The concept of art experience among beholders is well-known but lacks empirical studies on everyday art experiences among laypersons. In this bachelor thesis, the appearance of layperson beholders’ art experience is explored by a qualitative interview study method. LÄS MER

  4. 18. Parallel Operation of Grid-Forming Power Inverters

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alessia Camboni; [2023]
    Nyckelord :;

    Sammanfattning : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. LÄS MER

  5. 19. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  7. 20. Developing an ML-based model for RF tuning of the DTL machine at ESS

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Amin Hosseini Nejad; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The European Spallation Source (ESS) infrastructure is being constructed in Lund, and will be one of the most powerful research facilities of its type in the world. The ESS linear accelerator (linac) utilizes different accelerating sections where a wide variety of techniques should be employed to accelerate a beam of protons to 2 GeV kinetic energy through Radio Frequency (RF) cavities before being collided with a tungsten target for the final production of neutrons, through the process of spallation.
