   Abstract : Cone Beam Computed Tomography (CBCT) is a medical imaging technique used to visualize the internals of an object from a set of X-ray images. The X-ray images are taken with a cone shaped X-ray beam at many angles around the object being visualized. The images are then back projected through a volume forming a 3D representation of the object. READ MORE

3. 22. Genetic diversity and hardiness in Scots pine from Scandinavia to Russia

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Jenny Olsson; [2019]
   Keywords : Pinus sylvestris; recolonization history; genetic diversity; cold hardiness; clinal variation;

   Abstract : The postglacial recolonization of northern Europe supposedly originated from Western Europe and the Russian Plain, however, recent molecular and macrofossil-based investigations suggest that the history may be more complex than previously thought. This study aims to investigate the genetic diversity and population structure of Scots pine from Scandinavia to Russia to re-evaluate its recolonization history, and to examine whether the pattern of spatial genetic diversity has any adaptive significance.

   Abstract : The industry is moving towards a higher degree of automation and connectivity, where previously manual operations are being adapted for interconnected industrial robots. This thesis focuses specifically on the automation of tightening applications with pre-tightened bolts and collaborative robots. READ MORE

5. 24. Measuring the Risk-neutral Probability Distribution of Equity Index Options

   University essay from Linköpings universitet/Produktionsekonomi

   Author : Gustav Dackner; Linus Falk; [2019]
   Keywords : ;

   Abstract : The focus of this master thesis is to develop a model that measures the risk-neutral probability distributionof the future value of a portfolio consisting of options on the S&P 500 index. The cornerstone of the model is an explicit and thorough construction of the local volatility surface. The parametric model of Coleman etal. READ MORE

6. 25. Characterization of property variations in paperboard samples

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sofia Wretstam; [2018]
   Keywords : Paperboard; variability; property; tensile strength; surface roughness; thickness; distribution.;

   Abstract : In today’s paper and board production, quality control is made on a single cross direction (CD)sample from each tambour. As several different properties are analysed, only a limited number of measurement results are obtained for one property. READ MORE
