1. 1. Natural Fingerprinting of Steel

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Johannes Strömbom; [2021]
   Keywords : fingerprinting; laser speckles; speckle correlation; scattering transform; wavelets; feature detection;

   Abstract : 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. READ MORE

3. 2. 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)

   Author : Natalie Pettersson; [2017]
   Keywords : X-ray diffraction; Residual stress measurements; material removal; induction hardening; ESPI;

   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

4. 3. Skin dose measurement during radiation therapy of mastectomy patients using GafChromicTM EBT3 films.

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Madeleine Bergström; [2017]
   Keywords : Mastectomy; Radiation therapy; GafChromic; EBT3; microcirculation;

   Abstract : Purpose: The aim of this study was to develop a method of measuring changes in the skin microcirculation and skin dose for mastectomy patients in connection with the radiation treatment. The distribution of the skin dose, its dependence on the energy of the beam, field geometry and bolus material and the accuracy of the given skin dose in the treatment planning system were studied.

5. 4. Measurement of absorbed dose to the skin and its relation with microcircular changes in breast cancer radiotherapy

   University essay from Stockholms universitet/Fysikum

   Author : Chahed Yacoub; [2016]
   Keywords : Radiotherapy; Breast; Microcirculation; Skin;

   Abstract : Radiation therapy has been shown to increase local and regional control as well as overall survival with breast cancer, but the vast majority of patients develop acute skin reactions, which are in part related to microvascular changes. These reactions vary between different skin sites. READ MORE
