11. Summation-by-Parts Finite Difference Methods for Wave Propagation and Earthquake Modeling
Abstract : Waves manifest in many areas of physics, ranging from large-scale seismic waves in geophysics down to particle descriptions in quantum physics. Wave propagation may often be described mathematically by partial differential equations (PDE). Unfortunately, analytical solutions to PDEs are in many cases notoriously difficult to obtain.

12. Analytical photoacoustic model of laser-induced ultrasound in a planar layered structure
Abstract : A way of describing photoacoustic measurement techniques is listening to light. Another way is as sensor techniques for characterisation of materials by means of light and sound interacting with the material under investigation. READ MORE

13. Advancing Modeling and Tracking of Deformable Linear Objects for Real-World Applications
Abstract : Deformable linear objects (DLOs), such as cables, wires, ropes, and sutures, are important components in various applications in robotics. Although automating DLO manipulation tasks through robot deployment can offer benefits in terms of cost reduction and increased efficiency, it presents difficult challenges. READ MORE

14. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation
Abstract : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. READ MORE

15. A ground-borne noise prediction model for railway traffic in tunnels in bedrock
Abstract : Human life has become more manageable by the expansion of railway lines. However, despite providing convenience, railways increase noise and vibration in residential areas. Vibrations and noise generated by railways may harm human health, cause cosmetic damage and have an adverse impact on the environment. READ MORE
