1. The Book of Hours of Johannete Ravenelle and the Parisian Book Illumination Around 1400
Sammanfattning : Within the French book of hours C 517e in the manuscript collection of the University Library in Uppsala, the name of the owner, Johannete Ravenelle, appears in a prayer. Examination of the decoration, miniatures and texts demonstrates that ms C 517e is consistent with Parisian art and books of hours around 1400. 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. Averaged linear energy transfer and other beam quality descriptors inr elation to relative biological effectiveness
Sammanfattning : In radiotherapy with protons, a constant relative biological effectiveness (RBE) of 1.1 is traditionally applied, i.e. protons are assumed to be 10\% more effective than photons in killing cells. LÄS MER
4. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy
Sammanfattning : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.

5. Fixed structure LQ design with applications
Sammanfattning : This thesis deals mainly with the problem of designing structure constrained controllers (or fixed structure control design) which is a problem that occurs in many industrial control applications. In process industry for example, almost all control loops are closed with commercial PI controllers (which have specified structures). LÄS MER
