Particle image velocimetry (PIV) measurements and proper orthogonal decomposition (POD) are used to explore the turbulent structures in a ribbed channel. In this study, only one channel wall is equipped with square ribs which are oriented transversely to the main stream direction. The ribs obstruct the channel by 20% of its height and are arranged 10 rib heights apart. The results include mean str

Popular Abstract in Swedish Det är sedan länge känt att för samma bildkvalitet kan patientstråldosen variera kraftigt mellan två olika sjukhus för en och samma röntgenundersökning. Det finns ett stort utrymme för sänkning av patientstråldosen utan att undersökningens kvalitet påverkas. Vid optimering inom röntgendiagnostik balanseras patientstråldos mot bildkvalitet. Optimeringen kräver att man haOptimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. Two methods are used and further developed; fulfilment of image criteria (IC) and visual grading analysis (VGA). Clinical image quality de

This textbook in structural mechanics is based on the methodology of the finite element method. The understanding of basic elements of structural mechanics - springs, bars, beams and foundations - is gradually built up in one, two and three dimensions. Using these elements it is demonstrated how complex load-bearing structures can be modelled and analysed. Methods for linear as well as geometric a

Proficiency in writing is a central graduate attribute of higher education. In practice, this means that students are expected to acquire both generic and discipline-specific writing skills that will be beneficial for their professional lives. Although the learning outcomes for many courses include the ability to express oneself in writing, a predominant function of writing is that of mere testing
