  1. 21. Mostly Panel Econometrics : Essays on Asymptotic Analysis and Enhanced Inference

    Författare :Ovidijus Stauskas; Joakim Westerlund; Ignace De Vos; Milda Norkute; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometrics; Panel Data; Factor Models; Bootstrap; Forecasting; Non-Stationary Data; Common Correlated Effects; CCE;

    Sammanfattning : This thesis consists of five chapters which focus on panel data theory. Four of them analyze explicit panel data models and one chapter deals with time series forecasting model, where external panel data help us estimate unobserved explanatory variables. LÄS MER

  3. 22. On the Design of Electric Traction Machines : Design and Analysis of an Interior Permanent Magnet Synchronous Machine for Heavy Commercial Vehicles

    Författare :Rasmus Andersson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design of electrical machines; IPMSM; Electric propulsion; Thermal model; Skewing; Torque ripple analysis; Mechanical losses; Iron losses; Loss analysis; Heavy commercial vehicles;

    Sammanfattning : Recent years have proven the benefits of electrifying the road bound vehicle fleet. With new components entering, the general understanding as well as the components as such needs to be improved. LÄS MER

  4. 23. Morale in very old people : With focus on stroke, depression and survival

    Författare :Johan Niklasson; Yngve Gustafson; Hugo Lövheim; Aase Wisten; Sölve Elmståhl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morale; aged 80 and over; Sweden and Finland; Psychometrics testing; Feasibility studies; Quality of Life; Stroke; Depressive disorders; Geriatric psychiatry; Salutogenic factor; Survival; Longevity; Future-oriented optimism;

    Sammanfattning : Background: Morale is a multidimensional concept, often defined as a future-oriented optimism or pessimism regarding the problems and opportunities associated with ageing. Very old people, older than 80 years, constitute an age group that is expected to increase in Europe from 4.7% of the general population today to 12. LÄS MER

  5. 24. Distributions Of Fiber Characteristics As A Tool To Evaluate Mechanical Pulps

    Författare :Sofia Reyier Österling; Per Engstrand; Hans Höglund; Olof Ferritsius; Rita Ferritsius; Hans Ersson; Per Gradin; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; fibre; fiber characteristics; fiber dimension; fiber properties; mechanical pulp; FiberLab; raw data; distribution; fiber wall thickness; BIN; bonding ability influence; bonding indicator; bonding ability; fiber width; fibrillation; collapse resistance; laboratory sheet; fiber analyzer; optical analyzer; TMP; CTMP; SGW; sheet model; prediction; fiber characterization; hydrocyclone; fractionation; kernel density estimation; KDE; diffusion mixing; acoustic emission; F0.90; Norway spruce; Picea abies;

    Sammanfattning : Mechanical pulps are used in paper products such as magazine or news grade printing papers or paperboard. Mechanical pulping gives a high yield; nearly everything in the tree except the bark is used in the paper. This means that mechanical pulping consumes much less wood than chemical pulping, especially to produce a unit area of printing surface. LÄS MER

  7. 25. The Chirality-Flow Formalism and Optimising Scattering Amplitudes

    Författare :Andrew Lifson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spinor-helicity formalism; Chirality-flow formalism; Helicity amplitudes; Standard Model; QED; QCD; Optimisations; Colour expansion; Phenomenology; Fysicumarkivet A:2023:Lifson;

    Sammanfattning : This thesis is composed of five papers, which all attempt to optimise calculations of scattering amplitudes in high-energy-physics collisions. These scattering amplitudes are a key part of theoretical predictions for particle-physics experiments like the Large Hadron Collider at CERN. LÄS MER
