2. 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

3. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.
University essay from Mälardalens högskola/Framtidens energiAbstract : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.

4. Methods for including stiffness parameters from reduced finite element models in simulations of multibody systems
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : Two methods using lumped element (lumped parameter) methods to model flexible bodies have been presented. The methods are based on the concept of using a Guyan reduced stiffness matrix to describe the elasticity of a body. READ MORE

5. Modelling a piezoelectric-driven actuator for active flow control
University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolanAbstract : Flow control is an area of research of particular interest within automotive and aerospace industries since methods used to affect the fluid flow around vehicles can reduce drag and therefore lower their fuel consumption. One of these methods, which has generated a lot of interest in later years, is called active flow control and uses different types of actuators to impact the surrounding flow. READ MORE
