1. Regenerative Chatter Vibration in Indexable Drills : Modeling and Simulation
Sammanfattning : An indexable insert drill is a drill which uses cutting inserts to make holes. Undesirable sound generated by this type of drill has always been considered as a problem in workshops. The focus of this thesis is to investigate the mechanism behind these vibrations, to model it and to provide guidelines for reducing the sound in future drill designs. LÄS MER
2. Switched Bond Graphs : Simulation and Analysis
Sammanfattning : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.

3. Track circuits’ robustness : Modeling, measurement and simulation
Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER
4. Aircraft Systems Modeling : Model Based Systems Engineering in Avionics Design and Aircraft Simulation
Sammanfattning : Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models.

5. Modeling and Simulation of Dial-a-Ride and Integrated Public Transport Services
Sammanfattning : Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. LÄS MER
