1. Framtagande av mätmetod för koncentration av fixativ i bakvatten : Undersökning om FTIR lämpar sig som analysmetod med processvatten för en mjukpapperstillverkning
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Rexcell Tissue & Airlaid AB is a producer of paper products such as coloured tissue, where it is important to manufacture a product that does not release any colour during usage. To prevent colour bleeding, a fixative is added during the paper dyeing process. LÄS MER
2. Comparing Apples to Peers: Studying the Importance of Industry Affiliation for Private Company Discounts in Europe
D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : Private company transactions have been found to be, on average, valued lower than comparable public transactions, giving rise to what is often in the literature called a Private Company Discount (PCD). Building on previous literature, this study extends our understanding of how the occurrence of a PCD might differ between different industries, and what firm characteristics that could explain such cross-sectional heterogeneity.

3. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. LÄS MER
4. Evaluation of deep-learning image reconstruction for photon-counting spectral CT : A comparison between image domain- and projection domain-denoising
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : A promising new technology in medical imaging is photon-counting detectors (PCD). Itcould allow for images with higher resolution, less noise, improved material decomposi-tion while possibly reducing radiation exposure for patients. LÄS MER
5. Deep-learning image reconstruction for photon-counting spectral computed tomography
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : X-ray computed tomography (CT) has since its introduction in the early 1970s become one of the most important tools used for medical imaging. In CT, a large number of x-ray attenuation measurements are combined and reconstructed to form a three-dimensional image of the targeted area. LÄS MER
