1. 1. Development of a subject specific 3D knee finite element model to estimate the effect of weight loss on cartilage biomechanics

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Julius Dahlgren; [2022]
   Keywords : biomechanics; knee; cartilage; subject-specific; finite element; FE; FEM; weight loss; osteoarthritis; Technology and Engineering;

   Abstract : Osteoarthritis (OA) is a common musculoskeletal disorder that degrades articular cartilage and is a leading cause of disability worldwide. Overweight has been considered a major risk factor of knee OA, and it is known that weight loss may reduce the risk of knee OA. READ MORE

3. 2. Verification of elastomer characteristics in electro-mechanical linear actuator

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Rohit Karmungikar; [2022]
   Keywords : ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

   Abstract : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. READ MORE

4. 3. Domain Adaptation for Combined CT and CBCT Deep Learning Segmentation

   University essay from Lunds universitet/Matematik LTH

   Author : Jonas Berg; [2021]
   Keywords : CT; CBCT; Deep Learning; Medical Image Segmentation; Radiotherapy; Domain Adaptation; CycleGAN; Domain Adversarial Neural Network; U-Net; Data Augmentation; Machine Learning; Technology and Engineering;

   Abstract : Computed tomography (CT) segmentation models are frequently used within radiotherapy treatment planning, but similar models are not available to the related imaging modality cone beam computed tomography (CBCT) due to the scarcity of labeled data from this domain. Such models could have multiple clinical applications whereby it is of interest to study whether the CT segmentation models can be adapted to generalize to the CBCT domain. READ MORE

5. 4. Compression Characteristics of Elastomer Elements

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Rahul Nagaraj Dixit; [2021]
   Keywords : Continuum mechanics; Hyperelasticity; Mooney Rivlin; Rack and Pinion; Kontinuummekanik; Hyperelasticitet; Mooney Rivlin; Kuggstångsväxel;

   Abstract : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. READ MORE

6. 5. Finite Element Head ModelPersonalization by Mesh Morphing

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

   Author : Yann Levin; [2021]
   Keywords : Biomechanics; Finite element; Head models; Image Registration; Mesh morphing; Personalization.;

   Abstract : Finite Element (FE) head models are very convenient tools forthe study of Traumatic Brain Injuries (TBIs) but lack significantanatomical details for the investigation of morphology or age-dependantinjury mechanisms. In this context, the use of deformable registrationalgorithms for the generation of personalized head models is veryconsistent for the development of improved protection systems likehelmets. READ MORE
