16. Sensorlos reglering av en PMSM
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : This thesis is done together with KTH and Husqvarna AB. Husqvarna is one of the leading producers of outdoor power equipment in the world. A chainsaw developed by Husqvarna, that is driven by a permanent magnet synchronous motor (PMSM), is currently controller by a sensorless brushless DC-based controlling strategy. LÄS MER
17. Velocity estimation in land vehicle applications - Sensor Fusion using GPS, IMU and Output-shaft
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : In this project an alternative velocity-signal for Scania’s heavy-duty vehicles was investigated. The current velocity estimation is based on wheel-encoders obtained from other control-units like ABS- and EBSsystems. Furthermore the wheel-encoders may have poor properties at both high and low velocites. LÄS MER
18. Vilken kompetens urskiljer tester vid rekrytering av brandmän? : En kvalitativ studie om ett brandförsvars uppfattningar om rekryteringsverktygens relevans vid rekrytering av brandmän
Kandidat-uppsats, Umeå universitet/Pedagogiska institutionenSammanfattning : Studien är genomförd i samarbete med det studerade brandförsvaret som infört nya riktlinjer kring deras rekryteringsprocess för brandmän. Studien har syftat till att undersöka och beskriva uppfattningar om brandförsvarets rekryteringstesters relevans i relation till brandmäns kompetens. LÄS MER
19. Investigation of Galvanic Corrosion between Graphite Gaskets and Stainless Steel Flanges
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : At Forsmark, several cases of suspected galvanic corrosion have been detected and believed to be caused by an inappropriate use of graphite gaskets in brackish water. This report studies the likelihood of galvanic corrosion between the graphite gasket and stainless steels and aims to be a reference when investigating galvanic corrosion in the future. LÄS MER
20. The Process Influence on Strength Properties of an Austenitic Stainless Steel (254 SMO)
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : This work has been performed at Outokumpu Stainless AB, QPE, in Degerfors where focus is on production of hot rolled tailor-made quarto plate in special stainless steel grades such as highly alloyed austenitics and duplex steel grades. After a period with low values in strength and a lot of deviations in tensile tests for the highly alloyed austenitic stainless steel, 254 SMO, there was a need to investigate what influence some parameters during process has on strength values.
