Krielaart, Thomas (author)Crane hardstands serve as crucial platforms for supporting heavy lifting equipment and ensuring operational efficiency. However, crane hardstands are not infinitely stiff and will deform upon loading. Uneven loading during wind turbine installation will result in differential deformation of the crane hardstand, causing the crane to tilt. A small...master thesis 2023

Talsma, Maaike (author)Osteoarthritis (OA) is a progressive joint degeneration disease resulting in joint pain, stiffness, and loss of mobility. Among patients with anterior cruciate ligament reconstruction (ACLR), OA incidence is increased. Articular cartilage (AC) degeneration is irreversible, therefore prevention and early detection are essential. Specifically, the...master thesis 2023

van Vliet, Christian (author)In problems with missing data, the data are often considered to be missing at random. This assumption can not be checked from the data. We need to assess the sensitivity of study conclusions to violations of non-identifiable assumptions. This thesis performs Bayesian sensitivity analysis for a missing data model with life time outcomes and...master thesis 2023

Shi, Dongdong (author)Wind energy becomes more and more popular since it is environmentally friendly. Wind farm control is one of the most popular topics and it works on steering the wind farm to extract energy from wind as much as possible. Generally, the model capturing wake effects between turbines in the wind farm plays a role in wind farm control. The existing...master thesis 2023

Kisoensingh, Arvind (author)Flexural shear failure is a brittle failure mode that can occur in reinforced concrete (RC) beams without stirrups due to the combination of flexural and shear stresses. The failure mode begins with vertical flexural cracks at the bottom of the RC beam central span area due to flexural tensile stresses, followed by diagonal cracks. During...master thesis 2023
