  1. 21. Accelerating longitudinal spinfluctuation theory for iron at high temperature using a machine learning method

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Marian Arale Brännvall; [2020]
    Keywords : Machine learning; longitudinal spin fluctuations; kernel ridge regression;

    Abstract : In the development of materials, the understanding of their properties is crucial. For magnetic materials, magnetism is an apparent property that needs to be accounted for. There are multiple factors explaining the phenomenon of magnetism, one being the effect of vibrations of the atoms on longitudinal spin fluctuations. READ MORE

  3. 22. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Caroline Holmström; [2020]
    Keywords : ;

    Abstract : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. READ MORE

  4. 23. A theoretical study of longitudinal and transverse spin fluctuations in disordered Fe64Ni36 alloys

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Amanda Ehn; [2020]
    Keywords : INVAR effect; longitudinal spin fluctuations; transversal spin fluctuations;

    Abstract : That certain iron and nickel alloys exhibit an anomalously low thermal expansion of a wide temperature range has been observed since late 1800s, and this effect is known as the Invar effect. Since then, many theories have been proposed to explain the phenomenon. READ MORE

  5. 24. Optimization of Simultaneous Multi Slice EPI for clinical fMRI

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Andrea Fingerhut; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Functional MRI is a method used to map brain functionality, where the blood oxygen level (BOLD) imaging method is frequently used. Stimulation of neurons leads to an increase in energy and oxygen consumption and signal can be detected since oxygen changes the magnetic properties of the blood. READ MORE

  6. 25. The Effect of Using DMSO as a Cosolvent for Ligand Binding Studies

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Simon Birgersson; [2019]
    Keywords : Galectins; Nuclear Magnetic Resonance; NMR; Biophysical Chemistry; Relaxation; CPMG; ITC; Biofysikalisk Kemi; Kärnmagnetisk resonans; Technology and Engineering; Chemistry; Biology and Life Sciences;

    Abstract : DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. READ MORE
