1. Washing Machine Design Optimization Based on Dynamics Modeling
Abstract : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

2. Lattice Boltzmann simulations of tracer diffusion in microswimmer suspensions
Abstract : Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. READ MORE

3. Simulation of collective phenomena in microswimmer suspensions
Abstract : Collective motion is ubiquitous in biological and synthetic systems across manylength- and timescales. On the macroscopic scale, examples include schools of fish, herds of sheep and flocks of birds. On the microscopic scale, bacteria, algae and synthetic self-propelled particles exhibit a range of collective phenomena. READ MORE

4. Low-cost control of discontinuous systems including impacts and friction
Abstract : For a successful design of an engineering system it is essential to pay careful attention to its dynamic response. This is particularly true, in the case of nonlinear systems, since they can exhibit very complex dynamic behaviour, including multiple co-existing stable solutions and chaotic motions, characterized by large sensitivity to initial conditions.

5. Advances In Heavy Vehicle Dynamics with Focus on Engine Mounts and Individual Front Suspension
Abstract : The main objective of the research presented in this thesis is to enhance driver comfort and handling of a heavy truck that in turn leads to better vehicle safety and stability. The focus has been put on studying two suspension systems of the truck, engine and front axle suspensions, due to their significant impact on the dynamic performance of the vehicle. READ MORE
