1. A Central Rapidity Straw Tracker and Measurements on Cryogenic Components for the Large Hadron Collider
Sammanfattning : This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.

2. Computer-aided detection and novel mammography imaging techniques
Sammanfattning : This thesis presents techniques constructed to aid the radiologists in detecting breast cancer, the second largest cause of cancer deaths for western women. In the first part of the thesis, a computer-aided detection (CAD) system constructed for the detection of stellate lesions is presented. LÄS MER
3. Stereoselective Nucleophilic Additions to Aldehydes and Synthesis of α-Amino-β- Hydroxy-Esters
Sammanfattning : This thesis deals with the development of new reaction methodology as well as stereochemical investigations. The first part concerns the investigation of 1,2- and merged 1,2- and 1,3- asymmetric induction in Mukaiyama aldol additions to α-heteroatom and α,β- heteroatom substituted aldehydes respectively.

4. Patient Safety - Cultural Perspectives
Sammanfattning : Background: Shared values, norms and beliefs of relevance for safety in health care can be described in terms of patient safety culture. This concept overlaps with patient safety climate, but culture represents the deeprooted values, norms and beliefs, whereas climate refers to attitudes and more superficial manifestations of culture.

5. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Sammanfattning : Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. LÄS MER
