6. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER
7. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

8. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/MaterialteoriSammanfattning : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. LÄS MER
9. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER
10. Machine Learning-based MIMO Indoor Positioning
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER
