1. 1. Head impact detection with sensor fusion and machine learning

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

   Author : Aron Strandberg; [2022]
   Keywords : head impact detection; sensor fusion; 3D; machine learning; support vector machine; random forests;

   Abstract : Head injury is common in many different sports and elsewhere, and is often associated with differentdifficulties. One major problem is to identify and value the injury or the severity. Sometimes there is no sign of head injury, but a serious neck distortion has occurred, causing similar symptoms as head injuries e.g. READ MORE

3. 2. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

   University essay from KTH/Hållfasthetslära

   Author : Philip Singh; [2022]
   Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

   Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

4. 3. Semantic Segmentation of Oblique Views in a 3D-Environment

   University essay from Linköpings universitet/Datorseende

   Author : Victor Tranell; [2019]
   Keywords : Semantic segmentation; 3D segmentation; oblique views; multiview segmentation; satellite imagery; convolutional neural networks;

   Abstract : This thesis presents and evaluates different methods to semantically segment 3D-models by rendered 2D-views. The 2D-views are segmented separately and then merged together. READ MORE

5. 4. Evaluation of Test Methods for Football Helmets Using Finite Element Simulations

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

   Author : Aðalheiður Gunnarsdóttir; [2019]
   Keywords : Concussion; Football Helmets; Test methods; FE simulations;

   Abstract : Introduction: Concussions in American Football are of a major concern due to highly reported injury rates. The importance of properly designed helmets have shown effect in reducing the risk of injuries, such as skull fractures. However, they are not as effective in reducing the risk of concussion.

6. 5. 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.
