1. Thermal Modelling of Permanent Magnet Synchronous Motor Windings in Heavy-Duty Electric Vehicles
University essay from Linköpings universitet/FordonssystemAbstract : A significant challenge with permanent magnet synchronous motors (PMSMs) is thermal management. Thermal stress can lead to irreversible damage to components, and to enable efficient cooling, a thermal model is needed. READ MORE

2. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

3. Comparing Four Modelling Methods for the Simulation of a Soft Quadruped Robot
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A soft quadruped robot is being developed at the Department of Machine Design and Department of Production Engineering at KTH. The legs of the robot consist of four continuum actuators that can achieve complex movements. In order to efficiently develop gaits for the robot, reinforcement learning will be used. READ MORE

4. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

5. Hydrological modelling of a recycling facility and landfill
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : A parsimonious lumped model for simulating a catchment composed of a landfill and recycling facility were developed. The modelling results showed an acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation.
