1. 1. Swedish Dimensional Adjectives

   Författare :Anna Vogel; Staffan Hellberg; Lena Ekberg; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; dimensional adjectives; semantics; cognitive linguistics; Swedish; spatial; antonymy; prototype theory; polysemy; corpus-based; elicitation test; Languages and linguistics; Språkvetenskap;

   Sammanfattning : The purpose of this study is to give a thorough and detailed account and analysis of the semantics of twelve Swedish dimensional adjectives: hög ’high/tall’, låg ’low’, bred ’broad/wide’, smal ’narrow’ vid ’broad’, trång ’narrow’, tjock ’thick’, tunn ’thin’, djup ’deep’, grund ’narrow’, lång ’long’ and kort ’short’. Focus has been placed on their spatial, non-metaphorical sense. LÄS MER

3. 2. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach

   Författare :Richard Lindqvist; Lars Mattsson; Martin Helgoson; KTH; []
   Nyckelord :Geometrical; dimensional; measurement planning; controllability; GMCP; quality assurance matrix and methodology; QAM; critical key characteristic;

   Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.

4. 3. Phenomenological studies of dimensional deconstruction

   Författare :Tomas Hällgren; Tommy Ohlsson; Stefan Antusch; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dimensional deconstruction; higher-dimensional gauge theories; neu- trino mixing; neutrino oscillations; universal extra dimensions; ADD models; Ka- luza{Klein dark matter; Other physics; Övrig fysik;

   Sammanfattning : In this thesis, two applications of dimensional deconstruction are studied. The first application is a model for neutrino oscillations in the presence of a large decon- structed extra dimension. In the second application, Kaluza{Klein dark matter from a latticized universal extra dimension is studied. The goal of these projects have been twofold. LÄS MER

5. 4. Aspects of Dimensional Deconstruction and Neutrino Physics

   Författare :Tomas Hällgren; Tommy Ohlsson; Stephan J. Hubber; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensional deconstruction; higher-dimensional gauge theories; discretized gravity; neutrino mass; neutrino mixing; neutrino oscillations; Engineering physics; Teknisk fysik;

   Sammanfattning : The existence of at or curved extra spatial dimensions provides new insights into several of the problems which face the Standard Model of particle physics, including the gauge hierarchy problem, the smallness of neutrino masses, and the dark matter problem. However, higher-dimensional gauge theories are not renormalizable and can only be considered as low-energy effective theories, with limited applicability. LÄS MER

7. 5. Electron Transport in Low Dimensional Systems

   Författare :Peter Ramvall; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high mobility; low-dimensional structures; III-V semiconductors; quantum wells; heterojunctions; quantum Hall effect; edge channels; Shubnikov-de Haas effect; alloy-disorder scattering; Y-branch switch; two dimensional electron gas; Fysik; Fysicumarkivet A:1996:Ramvall; Physics; spin splitting; mag;

   Sammanfattning : This thesis consists of experimental studies of transport properties in high mobility two dimensional electron gases (2DEGs). Two material systems are used, an AlGaAs/GaAs heterojunction and a GaInAs/InP quantum well. LÄS MER
