  1. 21. TMS stimulus-response asymmetry in lower limbs : Difference in stimulated muscles between dominant and non-dominant leg

    University essay from Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Author : Adna Pivac; [2022]
    Keywords : lower limbs; motor evoked potential; motor cortex; stimulus-response asymmetry; transcranial magnetic stimulation;

    Abstract : Transcranial magnetic stimulation (TMS) is a 37-year-old non-invasive tool and can be used for diagnostic, therapeutics, and research purposes. In research, TMS is mostly used to stimulate the motor cortex, resulting in a neuroelectric excitatory response called a motor evoked potential (MEP). READ MORE

  3. 22. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

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

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  4. 23. Induction powered percolator

    University essay from Jönköping University/JTH, Industridesign

    Author : Semir omerovic; [2022]
    Keywords : Industrial design; induction percolator; Concept exploration; C3 Scandinavian Lifestyle; product development;

    Abstract : This project was a collaboration with C3 Scandinavian Lifestyle to create an induction percolator. Certain points had to be considered and explored. How can the copper coil be used in the percolator, and how can the new technology be turned off at the specified temperature?The report will begin with a theoretical foundation. READ MORE

  5. 24. Characterizing coil windings noise due to compressive fault currents : A study to determine if there is a characteristic noise from transformer windings due to fault currents

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

    Author : Simon Lundgren; [2022]
    Keywords : Transformer windings; short circuit forces; current pulses; microphone; Comsol Multiphysics; FFT; Transformator lindningar; strömpulser; mikrofon; kortslutingskrafter; Comsol Multiphysics; FFT;

    Abstract : Transformers are essential for modern power distribution system. They are efficient and enable the voltages to be transformed up for transportation of electricity and back down for consumer use. The reliability of the transformer is affected by faults and fatigue of the copper. READ MORE

  6. 25. Radiofrequency-Induced Heating of a Deep Brain Stimulator Lead inside TEM Cells and inside a 3T MR-Scanner

    University essay from Umeå universitet/Radiofysik

    Author : Haider Shaban; [2022]
    Keywords : Medical Physics; MRI; ;

    Abstract : The use of non-ionizing radiation in the magnetic resonance imaging (MRI) made it a safer diagnostic technique in comparison to the X-ray imaging method. MRI can also produce soft tissue images with a very high contrast without contrast agent which is another advantage that made MRI an important imaging technique for studying the mechanism of the deep brain stimulation (DBS) and for targeting the desired regions in the brain that should be stimulated.
