11. Simulation of rail traffic : Methods for timetable construction,delay modeling and infrastructure evaluation
Abstract : This thesis covers applications and proposes methods for using simulation in a more effectiveway and also in a wider context than normally used. One of the proposed methods deals withdelay modeling that can be used in a calibration process. READ MORE

13. Adaptive and model-based control in laminar boundary-layer flows
Abstract : In boundary-layer flows it is possible to reduce the friction drag by breaking the path from laminar to turbulent state. In low turbulence environments, the laminar-to-turbulent transition is dominated by local flow instabilities – Tollmien-Schlichting (TS) waves – that exponentially grows while being con- vected by the flow and, eventually, lead to transition.

14. Vehicular Communication in Obstructed and Non Line-of-Sight Scenarios
Abstract : Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives. READ MORE

15. Mathematical Models and Algorithms for Wireless Network Design and Optimization
Abstract : Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions.
