1. 6. Distance Functions and Image Processing on Point-Lattices : with focus on the 3D face- and body-centered cubic grids

   Författare :Robin Strand; Gunilla Borgefors; Stina Svensson; Christer Kiselman; David Coeurjolly; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computerized image analysis; digital geometry; distance functions; non-standard grids; point-lattices; Image analysis; Bildanalys;

   Sammanfattning : There are many imaging techniques that generate three-dimensional volume images today. With higher precision in the image acquisition equipment, storing and processing these images require increasing amount of data processing capacity. Traditionally, three-dimensional images are represented by cubic (or cuboid) picture elements on a cubic grid. LÄS MER

3. 7. Contributions to the Metamathematics of Arithmetic: Fixed Points, Independence, and Flexibility

   Författare :Rasmus Blanck; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; arithmetic; incompleteness; flexibility; independence; non-standard models; partial conservativity; interpretability;

   Sammanfattning : This thesis concerns the incompleteness phenomenon of first-order arithmetic: no consistent, r.e. theory T can prove every true arithmetical sentence. The first incompleteness result is due to Gödel; classic generalisations are due to Rosser, Feferman, Mostowski, and Kripke. LÄS MER

4. 8. Improving the transparency and predictability of environmental risk assessments of pharmaceuticals

   Författare :Marlene Ågerstrand; Christina Rudén; Cynthia de Wit; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; environmental risk assessment; pharmaceuticals; transparency; predictability; accuracy; consistency; voluntary initiatives; reliability evaluation; non-standard test data.; Philosophy subjects; Filosofiämnen;

   Sammanfattning : The risk assessment process and the subsequent risk management measures need tobe constantly evaluated, updated and improved. This thesis contributes to that workby considering, and suggesting improvements, regarding aspects like userfriendliness,transparency, accuracy, consistency, data reporting, data selection anddata evaluation.

5. 9. Searches for New Physics in Single Photon Events and a Search for Charginos at the DELPHI Experiment

   Författare :Stefan Ask; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; DELPHI; single photon events; LEP; chargino search; supersymmetry; extra dimensions; Elementary particle physics; non standard neutino interactions.; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Ask;

   Sammanfattning : A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. LÄS MER

7. 10. Chemicals in consumer products : Bridging the gap between academic research and chemicals regulation

   Författare :Linda Molander; Christina Rudén; Magnus Breitholtz; Laura N. Vandenberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; consumer products; articles; chemicals; chemicals regulation; REACH; risk management; health risk assessment; non-standard toxicity studies; study evaluation; reporting guidance; endocrine disrupting compounds; bisphenol A; low dose effects; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Exposure to chemicals emitting from consumer products, such as clothes, electronic devices, toys and kitchen-ware, has emerged as an issue of public health and environmental concern. The use of chemicals having endocrine disrupting properties in commercial products is receiving particular attention as low dose exposures of such chemicals have been associated with adverse effects in both human and wildlife populations.
