21. Dynamic analysis of a novel electromagnetic transducer for hybrid vehicle and experimental verification
Sammanfattning : This thesis presents the results of the work carried out on the dynamic analysis and experimental performance measurements of a novel concept of electromagnetic system for hybrid vehicle powertrains. The main focus of this work is to present how this novel electromagnetic system can be operated in a hybrid vehicle and to show how a prototype of this system has succesfully been operated in a laboratory set-up.

22. A Broad View on the Interpretation of Electromagnetic Data (VLF, RMT, MT, CSTMT)
Sammanfattning : The resolution power of single Very Low Frequency (VLF) data and multi-frequency Radiomagnetotelluric (RMT) data in delineating conductive structures typical for the sedimentary cover and crystalline basement in Scandinavia is studied with a view to future developments of the technique to increasing the frequency range into the LW radio band. Airborne and ground VLF data are interpreted and correlated with RMT measurements made on the ground to better understand the resolution power of VLF data. LÄS MER
23. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces
Sammanfattning : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. LÄS MER
24. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Sammanfattning : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. LÄS MER
25. Three-Dimensional Modelling and Inversion of DC resistivity and Time Domain EM data using Multi-Resolution Framework
Sammanfattning : 3-D forward modelling and inversion techniques play an important role in data interpretation, but they are still computationally challenging tasks. Therefore, this thesis aims to improve forward modelling and inversion performance using novel multi-resolution (MR) grid approach. LÄS MER
