1. 6. In-plane Compressive Response of Sandwich Panels

   Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Leif Carlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sandwich; Finite Element Analysis FEA ; Fracture; In-plane compression; Other engineering mechanics; Övrig teknisk mekanik; Structural and vibration physics; Struktur- och vibrationsfysik;

   Sammanfattning : The high specific bending stiffness of sandwich structures can with advantage be used in vehicles to reduce their weight and thereby potentially also their fuel consumption. However, the structure must not only meet the in-service requirements but also provide sufficient protection of the vehicle passengers in a crash situation. LÄS MER

3. 7. Strength of Sandwich Panels Loaded in In-plane Compression

   Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Per-Lennart Larsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich; in-plane compression; energy absorption; debond; postbuckling; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The use of composite materials in vehicle structures could reduce the weight and thereby the fuel consumption of vehicles. As the road safety of the vehicles must be ensured, it is vital that the energy absorbing capability of the composite materials are similar to or better than the commonly used steel structures.

4. 8. Evaluation of Regularized Image Reconstruction for Clinical Positron Emission Tomography

   Författare :Elin Lindström; Mark Lubberink; Jens Sörensen; Anders Sundin; Anne Larsson Strömvall; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET CT; molecular imaging; image reconstruction; regularized reconstruction; quantification; oncology; neurology; cardiology; Medicinsk radiofysik; Medical Radiophysics;

   Sammanfattning : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. LÄS MER

5. 9. Förhållandet mellan praxis och teori inom etiken

   Författare :Niclas Lindström; Ulf Görman; Helena Röcklinsberg; Anders Nordgren; Centrum för teologi och religionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Practice; theory; norms; ideals; principles; moral philosophy; casuistry; discourse ethics; virtue ethics; theocentric ethics; pragmatism; experimental ethics; empirically informed ethics.; etik; etik;

   Sammanfattning : The main question of this thesis is if a practice is right because it is prescribed by an ethical theory, or if an ethical theory is right because it follows from certain practices? I propose the following definitions to illustrate the main alternatives: (1) if a practice is determined by an ethical theory and the ethical theory is not determined by practice, it is possible to speak of a top-down model of ethical thinking. (2) If a theory, conversely, is determined by a practice and the practice is not determined by theory, it can be described as a bottom-up model. LÄS MER

7. 10. From Conceivability to Possibility : An Essay in Modal Epistemology

   Författare :Anders Berglund; Sten Lindström; Joseph Almog; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Theoretical philosophy; Modal Epistemology; Teoretisk filosofi; Theoretical philosophy; Teoretisk filosofi; Theoretical Philosophy; teoretisk filosofi;

   Sammanfattning : This study deals with the thesis that conceivability implies possibility. Confronted with alleged counterexamples to this thesis, some philosophers have turned to what may be called “idealized” or “more demanding” notions of conceivability. LÄS MER
