1. Improved performance characteristics of induction machines with non-skewed symmetrical rotor slots
Sammanfattning : Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. LÄS MER
2. On the Design of Electric Traction Machines : Design and Analysis of an Interior Permanent Magnet Synchronous Machine for Heavy Commercial Vehicles
Sammanfattning : Recent years have proven the benefits of electrifying the road bound vehicle fleet. With new components entering, the general understanding as well as the components as such needs to be improved. LÄS MER
3. Investigations of Hematopoietic Stem Cells and Their Age-Associated Alterations
Sammanfattning : The hematopoietic stem cell (HSC) has and continues to be extensively investigated, and represents by far the most studied somatic stem cell. Development of various experimental technologies, including fluorescence activated cell sorting (FACS), have been crucial for research advancements within the hematopoietic field. LÄS MER
4. Energy-efficient Generating System for HVDC Off-shore Wind Turbine
Sammanfattning : This thesis investigates the design of energy efficient generating systems for off-shore wind turbines. For the generator part of the electric drive system, a surface mounted permanent magnet synchronous generator (SPMSG), an interior permanent magnet generator (IPMSG) as well as a synchronous reluctance generator (SynRG) have been investigated.

5. Understanding the heterogeneity of the hematopoietic stem cells
Sammanfattning : The hematopoietic system is replenished and maintained throughout life by rare hematopoietic stem cells (HSCs) that reside in the bone marrow (BM) of adult mammals. Over the last 20 years, the advancement in the field lead to the acknowledgement of the heterogeneity within the HSC compartment unraveling the presence of HSC subsets with certain mature blood lineage preferences so called lineage-biased (Li-bi) HSCs.
