In this project we developed a method to segment and visualize teeth roots from CT scan data. Our method is based on the level set method for the segmentation and the marching cubes method for the visualization. Most of the teeth segmentations had a good result when compared to a ground truth although there were some teeth and data sets that were problematic to segment. We give some reasons as to

Inom arbets- och organisationspsykologi har mycket forskning fokuserat stress i arbetslivet, men få studier har genomförts kring studenter. Studiens syfte var att undersöka om stress i form av kvantitativa krav är relaterat till ohälsa bland studenter.

The majority of industrial control systems today are distributed over networks. These systems tend to be complex, and can be difficult both to configure and to analyze; therefore, there is definitely a gain in being able to simulate the behaviour of such a system prior to the actual implementation. This master’s thesis investigates the possibility to simulate the ABB automation system 800xA by ex
