  1. 1. Oscillations in a complex sunspot: From theory to data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Femke Kranenbarg; [2024]
    Nyckelord :;

    Sammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. Optimal simultaneous excitation for identification of multivariable systems

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

    Författare :Gunnar Sigurðsson; [2023]
    Nyckelord :System identification; Simultaneous excitation; Experiment design; Model Predictive Control MPC ; Optimization; Multivariable systems; Systemidentifiering; Simultan excitation; Experimentdesign; Modell Predictive Control MPC ; Optimering; Multivariabla system;

    Sammanfattning : Having a accurate model of a system is essential for many applications today, especially those related to advanced process control. When executing a project often a lot of time is spent performing experiments on the real system to estimate a model. LÄS MER

  4. 3. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

  5. 4. Positive-Ion/Negative-Ion Coincidence (PINICO) Experiments on Water

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Bruno Moog; [2017]
    Nyckelord :PINICO; TOF; time-of-flight; time of flight; spectroscopy; coincidence spectroscopy; water; Physics and Astronomy;

    Sammanfattning : A new setup for versatile ion time-of-flight coincidence spectroscopy was built using a pre-existing negative ion time-of-flight spectrometer aligned with a short extension that may be used to detect photons, Auger electrons or positive ions. The extension was designed to be short to improve detection of photons, as they do not have a preferred direction for their emission, and high-momentum particles, which would miss the detector if it were placed farther from the interaction region.

  7. 5. Experimental set-up for near infrared fluorescence measurements during surgery

    Kandidat-uppsats, Biomedicinsk instrumentteknik; Tekniska högskolan

    Författare :Pascal Behm; [2013]
    Nyckelord :;

    Sammanfattning : In case a tumour grows in a tissue close to the lymphatic system, biopsies of the first draining lymph nodes connected to the tumour, also known as sentinel lymph nodes, allow determining if the cancer has already metastasized. Lymph node mapping is used in oncology surgery to find the patients lymph nodes connected to the tumour. LÄS MER
