1. Fracture simulation with a hyperelastic phase field model
University essay from KTH/HållfasthetsläraAbstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

2. Photoluminescence Mapping of Erbium Doped Lithium Niobate
University essay from KTH/Tillämpad fysikAbstract : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

3. Gender Norms, Temporal Flexibility, and Talent Misallocation
University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomiAbstract : To what extent do unequal gender roles in the household affect aggregate outputs when there is temporal inflexibility in the labor market? Following Goldin (2014) and Erosa et al. (2022)'s narrative of how disproportionate rewards to long hours create a source of distortion in the labor market, we explore the aggregate effects of gender differences exacerbated by nonlinear wage structures through a static model calibrated on US labor force data.

4. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. READ MORE

5. Neural Networks for Modeling of Electrical Parameters and Losses in Electric Vehicle
University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskapAbstract : Permanent magnet synchronous machines have various advantages and have showed the most superiorperformance for Electric Vehicles. However, modeling them is difficult because of their nonlinearity. READ MORE
