   Nyckelord :Lerwick; Shetland; Shetland dialect; Scottish Standard English; Accents of English; Vowel systems; Subsystems; The Scottish Vowel Length Rule; Vowel softening;

   Sammanfattning : This study presents a comprehensive description of the stressed vowel system of the local accent of Scottish Standard English spoken in Lerwick, Shetland. A judgement sample of eleven informants was obtained through a network model. LÄS MER

3. 22. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods

   Författare :Shiyang Meng; Svein Kleiven; Peter Halldin; Mazdak Ghajari; KTH; []
   Nyckelord :Head Injuries; Helmet; Injury Prevention; Motorcycle; Test Standard; Finite Element Method; Applied Medical Technology; Tillämpad medicinsk teknik;

   Sammanfattning : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. LÄS MER

4. 23. Contributions to Kernel Equating

   Författare :Björn Andersson; Fan Yang-Wallentin; Marie Wiberg; Alina A. von Davier; Jorge González; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; observed-score test equating; item response theory; R; equipercentile equating; asymptotic standard errors; non-equivalent groups with anchor test design; Statistics; Statistik;

   Sammanfattning : The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. LÄS MER

5. 24. Exotic Decays of Vector-Like Quarks and Development of a Test Procedure for the ITk Strip Module at the ATLAS Detector for the HL-LHC

   Författare :Thomas Mathisen; Elin Bergeås Kuutmann; Venugopal Ellajosyula; Richard Brenner; Freya Blekman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Standard Model; BSM; Composite Higgs; Fine-tuning; Naturalness; Vector-Like Quarks; HL-LHC; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The naturalness problem of the Standard Model (SM) challenges our understanding of the origin of mass. Several theories have been proposed to tackle the problem, one of them is the Composite Higgs Model (CHM) where the Higgs boson of the SM is not an elementary scalar but instead a composite object bound at a confinement scale of a TeV.

7. 25. Three Essays on Electricity Spot and Financial Derivative Prices at the Nordic Power Exchange

   Författare :Daniel Deng; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nord Pool; market efficiency; cointegration; rational expectation competitive storage model; BDS test; Hsiehâ??s third order moment test; nonlinear causality; EGARCH; convenience yield; call option;

   Sammanfattning : Essay I examines the market efficiency issues at the Nord Pool power exchange in the September 1995 - July 2002 period. A unique characteristic of this electricity exchange is the high hydropower proportion in the traded electricity; water in the hydro reservoir acting as hydropower inventory therefore plays an important role in the pricing of electricity.
