6. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

7. Acoustic Characterization of Catalyst
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER
8. Incorporating Flax Fiber Composites in Hypercar Panels
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. LÄS MER
9. Differentially Private Random Forests for Network Intrusion Detection in a Federated Learning Setting
Kandidat-uppsats, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)Sammanfattning : För varje dag som går möter stora industrier en ökad mängd intrång i sina IT-system. De flesta befintliga verktyg som använder sig utav maskininlärning är starkt beroende av stora mängder data, vilket innebär risker under dataöverföringen. LÄS MER
10. Förlustanalys av Elnätdistribution i Eskilstuna : En noggrann undersökning av elförluster och dess konsekvenser i ett område i Eskilstuna
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : This thesis explores the losses occurring in a specific region located in the southern part of Eskilstuna, where ESEM serves as the network owner. The study places particular emphasis on power factor and load factor as key factors. Its objective is to analyze and comprehend the extent of losses in the network and their implications. LÄS MER
