11. Analysis and Evaluation of Innovative Aero Engine Core Concepts
Sammanfattning : Turbofan engines, which power the majority of the modern aircraft today, have achieved such a high maturity that small improvements of the engine performance requires a large investment. More innovative technologies, including those related to the engine cores, become increasinglyattractive due to the high fuel price in recent years as well as the strict regulations on emissions.

12. Performance Modeling of Multi-core Systems : Caches and Locks
Sammanfattning : Performance is an important aspect of computer systems since it directly affects user experience. One way to analyze and predict performance is via performance modeling. In recent years, multi-core systems have made processors more powerful while keeping power consumption relatively low. LÄS MER
13. Three-body systems in the no-core shell model
Sammanfattning : In this thesis we present the ab initio no-core shell model (NCSM) and we use that framework to study 6He and 6Li computed with a realistic nucleon- nucleon interaction. In particular, we present results for the point-proton radius and the ground-state energy. LÄS MER
14. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects
Sammanfattning : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

15. Electromagnetic transformer modelling including the ferromagnetic core
Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
