1. 16. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making

   Författare :Yuichi Kanbe; Du Sichen; Leiv Kolbeinsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag metal reaction; equilibrium; kinetics; largest inclusion; statistics of extreme values; electrolytic extraction; cross section; inclusion morphology; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tau; top quark; ATLAS; LHC; TILE calorimeter; sensitivity; cross-section; standard model; physics; optimal filtering; energy reconstruction; hadronic tau decay; fysik; Physics;

   Sammanfattning : This thesis presents two studies conducted using the ATLAS detectorat the Large Hadron Collider. The first one is a technical study abouthow out-of-time pile-up affects energy reconstruction using the optimalfiltering 2 algorithm in the TILE calorimeter sub detector. The studyis conducted using a pulse simulator software that is also described. LÄS MER

5. 19. Exterior Colours at Rural Dwellings in Southern Sweden during the 19th Century - To increase knowledge regarding local differentiations

   Författare :Richard Kjellström; Bebyggelsevård; []
   Nyckelord :19th century; local colour schemes; rural; Johan Jöran Öller; SEM analysis; cross-section; exterior colour; farmhouses; dwellings;

   Sammanfattning : Abstract The project’s main objective is to verify the existence of local colours and colour schemes in the exteriors of buildings. The research focused on 19th century dwellings in the rural areas of southern Sweden. LÄS MER

7. 20. Mechanisms of Anion Reactions from the lab to ionospheres

   Författare :Fredrik Lindén; Wolf D. Geppert; Henrik Cederquist; Henning Zettergren; Einar Uggerud; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ab initio; anion; complex molecules; cross section; electron transfer; heavy ions; ionosphere; nitriles; quantum chemistry; spectroscopy; kemisk fysik; Chemical Physics;

   Sammanfattning : A multitude of heavy neutral and ionic molecules have been discovered by the Cassini Plasma Spectrometer in the ionosphere of Saturn's largest moon Titan. However, only three cyano anions were explicitly identified there, namely CN-, C3N- and C5N-. LÄS MER
