   Sammanfattning : Essay 1 - To evaluate measures of expectations I examine and compare some of the most common methods for capturing expectations: the futures method which utilizes financial market prices, the VAR forecast method, and the survey method. I study average expectations on the Federal funds rate target, and the main findings can be summarized as follows: i) the survey measure and the futures measure are highly correlated; the correlation coefficient is 0.

4. 3. Modelling, mapping and visualisation of flood inundation uncertainties

   Författare :Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cartography; flood; hydraulic modelling; GIS; map; uncertainty; visualisation; GIS; hydraulisk modellering; karta; kartografi; osäkerhet; visualisering; översvämning; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.

5. 4. Implementation of MRI gel dosimetry in radiation therapy

   Författare :Sven Bäck; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; uncertainty; detector; dosimeter; ferrous ions; gel dosimetry; magnetic resonance imaging; monomers; polymerisation; proton; treatment planning verification; radiation therapy; cancerology; Cytologi; onkologi; cancer;

   Sammanfattning : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. LÄS MER
