11. Energy in the Transportation System - A comparison of charging infrastructure scenarios
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. LÄS MER
12. Vilka möjligheter och hinder finns det för återbruk i byggbranschen?
Kandidat-uppsats,Sammanfattning : Byggbranschen står för en stor andel av Sveriges koldioxidutsläpp som bidrar till klimatförändringarna. Branschen behöver därmed ställa om från linjärt byggande till cirkulärt byggande där mer återbruk av byggprodukter och byggmaterial kan bidra till förändringen. LÄS MER
13. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. LÄS MER
14. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. LÄS MER
15. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. LÄS MER
