1. Learning Methods for Antenna Tilt Optimization
Sammanfattning : The increasing complexity of modern mobile networks poses unprecedented challenges to Mobile Network Operators (MNOs). MNOs need to utilize network resources optimally to satisfy the growing demand of network users in a reliable manner. LÄS MER
2. Towards Active Car Body Suspension in Railway Vehicles
Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER
3. Mechanics and acoustics of violin bowing : Freedom, constraints and control in performance
Sammanfattning : This thesis addresses sound production in bowed-string instruments from two perspectives: the physics of the bowed string, and bow control in performance. Violin performance is characterized by an intimate connection between the player and the instrument, allowing for a continuous control of the sound via the main bowing parameters (bow velocity, bow force and bow-bridge distance), but imposing constraints as well.

4. Radioastronomy Instrumentation for Herschel and APEX Projects
Sammanfattning : This thesis presents work done in developing instrumentation for sub-mm radio astronomyprojects.The first part covers Gaussian beam measurements for the Heterodyne Instrument for Far-Infrared (HIFI) of the Herschel Space Observatory project by the European Space Agency. LÄS MER
5. Embedded Measurement Systems
Sammanfattning : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. LÄS MER
