The increasing use of light metals and high strength steel in the automobile industry, demands for new sheet metal forming processes that can be applied successfully. In this thesis the subject of warm sheet metal forming is studied. In warm sheet metal forming the temperature of the blank is elevated either globally to one temperature evenly over the blank or locally where the flange region of th
The question whether students can be used as subjects in software engineering experiments is debated. In order to investigate the feasibility of using students as subjects, a study is conducted in the context of the Personal Software Process (PSP) in which the performance of freshmen students and graduate students are compared and also related to another study in an industrial setting. The hypothe
Test-Driven Development (TDD) is a software development approach where test cases are written before actual development of the code in iterative cycles. Context: TDD has gained attention of many software practitioners during the last decade since it has contributed several benefits to the software development process. However, empirical evidence of its dominance in terms of internal code quality,
We have computed the quark anti-quark expectation value in finite volume at two loop in chiral perturbation theory and compare it with a formula obtained in analogy to the Luscher formula for pion mass in finite volume. We observe that due to the small finite size correction at two loop it is not possible to obtain conclusions on the accuracy of the extended Luscher formula
The Swedish migration to America during the late 19th century and early 20th century was once the subject of a major research project at the University of Uppsala, called “Sweden and America after 1860”. The research project produced a large amount of dissertations on why, where and how people migrated as well as some research on what happened to the migrants in America. The return migration, desp
