1. Photospheric emission in gamma ray bursts : Analysis and interpretation of observations made by the Fermi gamma ray space telescope
Sammanfattning : The large flashes of radiation that are observed in GRBs are generally believed to arise in a relativistic jetted outflow. This thesis addresses the question of how and where in the jet this radiation is produced. LÄS MER
2. Multi-messenger emission from gamma-ray bursts
Sammanfattning : Multi-messenger astronomy is a very hot topic in the astrophysical community. A messenger is something that carries information. Different astrophysical messenger types are photons, cosmic rays, neutrinos, and gravitational waves. They all carry unique and complementary information to one another. LÄS MER
3. Two Languages, Two Scripts : Bilingual and Biscriptal Children with and without Reading Difficulties Read and Write in Persian (L1) and Swedish (L2)
Sammanfattning : The main aim of this dissertation was to explore L1 (Persian) and L2 (Swedish) reading and writing of 26 bilingual biscriptal children with and without reading difficulties (RD) (years 4–9). Previous studies have mainly focused on Latin scripts or one alphabetic and one non-alphabetic script with English as L1 or L2. LÄS MER
4. Failure Monitoring and Asset Condition Assessment in Water Supply Systems
Sammanfattning : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. LÄS MER
5. Statistical Investigations ofthe Emission Processes in Gamma-ray Bursts
Sammanfattning : Physical emission mechanisms responsible for gamma-ray bursts (GRBs) remain elusive to this day, 50 years after their discovery. Although there are well studied physical models, their power to explain the observed data is a matter of debate. LÄS MER
