2. 11. Quantification of pulmonary scintigraphy

   Author : Jiahua Xu; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Emphysema; Inhomogeneity; Perfusion; scintigraphy; SPECT; 99mTc-Technegas; Ventilation; V Q;

   Abstract : Modern nuclear medicine techniques, such as SPECT (single photon emission computed tomography), enable quantification and localisation of lung function in small lung elements, but appropriate methods are not yet available. The aim of the present project was therefore to develop and evaluate methods for mapping lung function in planar scintigrams and in SPECT. READ MORE

4. 12. Sensitive Forensic DNA Analysis : Application of Pyrosequencing and Real-time PCR Quantification

   Author : Hanna Andréasson; Marie Allen; Ulf Gyllensten; Pål Nyrén; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; forensic; sensitive DNA analysis; DNA quantification; mtDNA; Real-time PCR; Pyrosequencing; Genetik; Clinical genetics; Klinisk genetik;

   Abstract : The field of forensic genetics is growing fast and the development and optimisation of more sensitive, faster and more discriminating forensic DNA analysis methods is highly important. In this thesis, an evaluation of the use of novel DNA technologies and the development of specific applications for use in forensic casework investigations are presented. READ MORE

5. 13. Towards Changeability Quantification for Product-Service Systems Design

   Author : Raj Jiten Machchhar; Alessandro Bertoni; Johan Wall; Fredrik Elgh; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Changeability quantification; early design; Uncertainty; Value robustness; Operational Scenario; Product-Service Systems; Systems Engineering.; Maskinteknik; Mechanical Engineering;

   Abstract : Tough competition and volatile global markets have pushed the manufacturing industries to develop solutions more customer-centric with optimal utilization of resources. One of the key reasons behind developing a customer-centric solution is the increased customer value that imparts a competitive edge to the manufacturing industries, eventually leading them to sustain their businesses.

6. 14. Uncertainty Quantification and Numerical Methods for Conservation Laws

   Author : Per Pettersson; Jan Nordström; Gianluca Iaccarino; Gunilla Kreiss; Rémi Abgrall; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; polynomial chaos; stochastic Galerkin methods; conservation laws; hyperbolic problems; finite difference methods; finite volume methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets.

7. 15. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy

   Author : Katarina Sjögreen Gleisner; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; 131-I; Clinical physics; SPECT; conjugate-view; volume quantification; activity quantification; image registration; image segmentation; medicinsk instrumentering; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

   Abstract : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. READ MORE
