11. Fault location in resonant earthed medium voltage distribution systems
Sammanfattning : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

12. Robot system for flexible 3D friction stir welding
Sammanfattning : Applying Friction Stir Welding (FSW) on complex joint geometries requires not only a machine with 3-dimesional work space capacity, but also a sound definition of the part geometry as well as knowledge about the process. Having a joining process, such as FSW, with great characteristics from both seam quality and environmental perspective, but yet only a minor presence in the manufacturing industry may be related to flexibility and cost issues.

13. A Mutation-based Framework for Automated Testing of Timeliness
Sammanfattning : A problem when testing timeliness of event-triggered real-time systems is that response times depend on the execution order of concurrent tasks. Conventional testing methods ignore task interleaving and timing and thus do not help determine which execution orders need to be exercised to gain confidence in temporal correctness. LÄS MER
14. “Bridal Couples" : On Hybridity in Conceptual Chinese Photography 1995–2009
Sammanfattning : Chinese art of the 1990s responded to the many changes in the environment and thereby to changes in personal lives. Many Chinese artists of the time were therefore concerned with their selves and their works reveal explorations of personal identity. LÄS MER
15. Entrepreneurial identity formation-in-practice : Immigrant women entrepreneurs' lived practices and experiences within gender, ethnicity and class relations
Sammanfattning : This dissertation, comprising four appended papers, examines what entrepreneurs actually do in order to manage the intrinsic social complexity pertaining to relations of power and culture involved in entrepreneurial undertakings. The studies share the common interest in probing into the ways inwhich fundamental social divisions and conflicts, namely gender, ethnicity and class are inscribed into the entrepreneurs through the organization of difference (Ashcraft, 2012) and how these shape and are shaped by the identity construction processes of individual entrepreneurs.
