Title of Thesis: Effect of Initial Curvature of Printed Wiring Board on Vertical Stresses in Interconnects Mark Mifsud, Master of Science, 2015 Thesis directed by: Professor Abhijit Dasgupta Department of Mechanical Engineering During the solder reflow process used for attaching surface mount packages to printed wiring boards (PWBs), the possibility exists for the PWB and component to warp and ...

Changes to software systems often entail a loss of quality, especially if they have to be accomplished under pressure of time. Long-term software projects must counter this phenomenon one way or the other to preserve long-term maintainability. This paper presents the results of a case study trying to improve an extensive low-quality code base by object-oriented and tool-supported refactoring. T...

We study the barycentric straightening of simplices in higher rank irreducible symmetric spaces of non-compact type. We show that, for an n-dimensional symmetric space of rank r ≥ 2 (excluding S L(3,R)/S O(3) and S L(4,R)/S O(4)), the p-Jacobian has uniformly bounded norm, provided p ≥ n − r + 2. As a consequence, for the corresponding non-compact, connected, semisimple real Lie group G, in deg...

Contrary to initial persuasion, up to now there is no standard fieldbus but almost 50 different systems with deterministic characteristics regarding technical functions, application and popularity. But not every bus fits industrial use (fig. 1). Fig. 1: Encoder installed at a straightening machine in a sheet metal processing application. Multiturn absolute encoders with modular bus covers for c...

Molecular dynamics simulations of smooth and striated muscle myosin regulatory light chain (RLC) N-terminal extension (NTE) showed that diphosphorylation induces a disorder-to-order transition. Our goal here was to further explore the effects of mono- and diphosphorylation on the straightening and rigidification of the tarantula myosin RLC NTE. For that we used MD simulations followed by persis...

Aortic dissection (AD) is a life-threatening cardiovascular disease with high mortality rate. The accurate and generalized 3-D reconstruction of AD from CT-angiography can effectively assist clinical procedures surgery plans, however, clinically unavaliable due to the lacking efficient tools. In this study, we presented novel multi-stage segmentation framework for type B extract true lumen (TL)...
