Sammanfattning : In this study we highlight the influence of mean dilatation and mean density gradient on the Reynolds stress modeling of compressible, heat-releasing and supercritical turbulent flows.Firstly, the modeling of the rapid pressure-strain correlation has been extended to self-consistently account for the influence of mean dilatation.

Sammanfattning : Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. LÄS MER
Sammanfattning : Network service providers are struggling to reduce cost while at the same time improving customer satisfaction. This thesis addresses three relevant underlying challenges to achievieng these goals: - managing an overwhelming flow of low-quality alarms - understanding the structure and quality of the delivered services - automation of service configurationAll of the these add to an operator's operational costs since manual work is required in order to understand the alarm and service status as well as for configuring new services.

Sammanfattning : Two of the most important challenges in network service assurance are * an overwhelming ﬂow of low-quality alarms * to understand the structure and quality of the delivered services This thesis proposes solutions for alarm and service monitoring that addresses monitoring of large scale multi-service mobile networks. The work on alarms are based on statistical analysis of data collected from a real-world alarm ﬂow and an associated trouble ticket database containing the network administrators expert knowledge.
