1. 1. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

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

   Author : Rishabh Raj; [2022]
   Keywords : Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

   Abstract : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. READ MORE

3. 2. Diffusion-Based MR Methods for Measuring Water Exchange

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Shan Cai; [2022]
   Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

   Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE

4. 3. Reaction Wheel Performance Characterisation and Assessment of Electromagnetic Interactions with Magnetic Torquers

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Leonie Sander; [2021]
   Keywords : Reaction Wheel; Magnetic Torquers; Electromagnetism; Space Mechanism; Attitude Control;

   Abstract : Having an in-depth knowledge on the performance characteristics of space mechanisms in flight operation, with special attention to nominal vs. anomalous performance, is vital for mission success. READ MORE

5. 4. Characterization of Magneto-Dielectric Materials for Microwave Devices

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Joseph Lazraq Byström; [2020]
   Keywords : magneto-dielectric materials; permittivity; permeability; losses; antenna and filter miniaturization;

   Abstract : There is an increasing interest in using new composite materials in microwave devices, to reduce size and weight while maintaining similar performances. A new promising material group is named magneto-dielectric materials, which have the permittivity and permeability values both larger than one. READ MORE

6. 5. Consequences of Magnetic Properties in Stainless Steel for a High-efficiency Wave Power Generator

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Mohamed Sheikh Abdi; Yosef Gebresilassie; [2018]
   Keywords : stainless steel; wave power; permeability;

   Abstract : A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. READ MORE
