  1. 1. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Markus Back; [2020]
    Keywords : Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Abstract : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. READ MORE

  2. 2. Robust Drone Mission in the Arctic

    University essay from Uppsala universitet/Signaler och system; Uppsala universitet/Signaler och system

    Author : Elvira Brenner; Oscar Hultmar; [2020]
    Keywords : ;

    Abstract : During environmental research projects in the Arctic region AFRY has come across an unproportionally high number of cases where the navigation of drones have not worked as intended, compared to other regions. The main objective of this thesis is to investigate the cause of these navigational problems and determine the main cause. READ MORE

  3. 3. Automatic Whiteboard Eraser : A systematic and automated process

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

    Author : David Danelia; Nanitza Gonzalez Allendes; [2019]
    Keywords : Mechatronics; Magnet; Whiteboard; Continuous rotation servo motor; IR Sensor; Gyroscope.; Mekatronik; Magnet; Whiteboard; Kontinuerlig rotationsservomotor; IR Sensor; Gyroskop.;

    Abstract : The whiteboard is a tool being used in several different facilities around the world. However, erasing the ink off the board can be unnecessarily time consuming and distracting. The purpose of the project was therefore to create a demonstrator to automate the process with a few restrictions. READ MORE

  4. 4. Paddle stirrer to a reverberation chamber

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi; Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andrea Mastrorilli; Josefin Holmgren; [2019]
    Keywords : paddle stirrer; reverberation chamber; control system; encoder; magnetic encoder; paddle-omrörare; modväxlande kammare; styrsystem; sensor; magnetisk sensor;

    Abstract : Halmstad University is currently equipped with an Echo-free chamber to perform EMC testing, but no reverberation chamber. The construction of a paddle stirrer to be utilized in Halmstad University would drastically reduce the time required to perform EMC testing, since reverberation chambers are more efficient than Echo-free chambers for these kind of tests.

  5. 5. Modelling the Magnetic Influence of a Jet Aircraft : A study on the magnetic interference of an aircraft configuration and its effect on a magnetometer

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Erik Sandlund; [2019]
    Keywords : Magnetic fields; magnetic interference; electromagnetic field theory; simulations; engineering; finite-element method; jet engines; aircraft; submarines;

    Abstract : Aircraft have been used for the detection of submarines since World War II. The basic concept is to attach a sensor to the back of an aircraft. Since the aircraft is a moving metallic object, it is bound to generate a great deal of interference. READ MORE
