1. Natural Fingerprinting of Steel
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : A cornerstone in the industry's ongoing digital revolution, which is sometimes referred to as Industry 4.0, is the ability to trace products not only within the own production line but also throughout the remaining lifetime of the products.

2. Simulated Laser Triangulation with Focus on Subsurface Scattering
University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakultetenAbstract : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.

3. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting
University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

4. Deformation in the Achilles Tendon when Running with Minimalistic Shoes : Review of Speckle Tracking Algorithm
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : The main goal of the project was to compare how the Achilles tendon is affected while running with traditional shoes, minimalistic shoes and barefoot. Displacement and strain were calculated both for different shoes and for different foot strike patterns. READ MORE

5. Investigation of material removal techniques for residual stress profile determination on induction hardened steel
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : The residual stress profile is a major factor on the fatigue life of components that are subjected to cyclic loading. In order to measure these stresses x-ray diffraction (XRD) is commonly used. The penetration depth of x-rays is limited for this method and thus, it must be combined with material removal to determine in-depth stress profiles. READ MORE
