1. Kommunikationsmodeller inom public relations
Sammanfattning : Once a year for over forty years public relations’ practitioners in Sweden gathers, the political week in Almedalen, in the town of Visby. There they exchange knowledge and experience on all types of subjects using different and common communication models whether they are aware of them or not. LÄS MER
2. Experimental studies of radiation-induced dissolution of UO2 : The effect of intrinsic solid phase properties and external factors
Sammanfattning : Dissolution of the UO2 matrix is one of the potential routes for radionuclide release in a future deep geological repository for spent nuclear fuel. This doctoral thesis focuses on interfacial reactions of relevance in radiation-induced dissolution of UO2 and is divided in two parts:In the first part, we sought to explore the effects of solid phase composition:The impact of surface stoichiometry on the reactivity of UO2 towards aqueous radiolytic oxidants was studied.

3. Next Generation Wideband Antenna Arrays for Communications and Radio Astrophysics
Sammanfattning : Wideband, wide-scan antenna arrays are a promising candidate for the future wireless networks and as well as an essential part of experimental radio astrophysics. Understanding the underline physics of the element performance in the array environment is paramount to develop and improve the performance of array systems. LÄS MER
4. Efficient Methods to Calculate Mutual Coupling between Generic Antennas on Large Platforms
Sammanfattning : This thesis presents research on methods for calculating the mutual coupling between antennas. The mutual coupling between antennas is a measure of the amount of energy transmitted from one antenna that is received by another, and is a key parameter when installing antennas on platforms, such as aircraft.

5. Thermal Barrier Coatings for Diesel Engines
Sammanfattning : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.
