1. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties
University essay from KTH/MaterialvetenskapAbstract : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. READ MORE

2. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project
University essay from Uppsala universitet/GeofysikAbstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

3. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

4. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit
University essay from Stockholms universitet/FysikumAbstract : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. READ MORE

5. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)
University essay from Uppsala universitet/GeofysikAbstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.
