  1. 6. ”Man fyller det med mer information helt enkelt”: en fenomenografisk studie om studenters upplevelse av geologisk tid

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jennie Mari Lundqvist; [2020]
    Nyckelord :Geologisk tid; geovetenskaplig didaktik; geologisk tidsskala; gester; visualisering; SOLO; Earth and Environmental Sciences;

    Sammanfattning : Geologisk tid är inte bara ett tröskelbegrepp, det är en central del i hur vi erfar geovetenskapliga fenomen som utspelar sig på en rumtids-skala som sträcker sig från mikro (exempelvis molnbildning) till makro (exempelvis plattektonik). Om vi vill förstå geovetenskapliga fenomen måste vi gå från det konkreta till det ab-strakta, vi måste gå från att kunna se och ta på fenomen till att enbart kunna föreställa oss fenomen inne i våra hu-vuden.

  2. 7. Structural integrity of highly ionized peptides

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Ibrahim Eliah Dawod; [2019]
    Nyckelord :X-ray free-electron laser; X-ray imaging; XFEL; Computer simulations; Radiation damage; Ab-initio molecular dynamics; DFT; TDDFT; Excited states; Femtosecond; Bioimaging;

    Sammanfattning : In order to understand the behaviour and function of proteins, their three dimensional structure needs to be known. Determination of macro-molecules’ structures is done using X-ray diffraction or electron microscopy, where the resulting diffraction pattern is used for molecular reconstruction. LÄS MER

  3. 8. Preparing parts for Wire and Arc Additive Manufacturing (WAAM) and net-shape machining

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Isak Koskenniemi; [2019]
    Nyckelord :Additive manufacturing; AM; Wire and Arc Additive Manufacturing; WAAM;

    Sammanfattning : WAAM is a relatively unexplored additive manufacturing method. Although research in this area has been performed for some years and the hardware is relatively cheap, the method is not widely used. As the name suggest, it uses wire and an arc welding equipment to deposit beads on top of each other to create a geometry. LÄS MER

  4. 9. Efficiency and Automation in the Interface between Airframe Development and Production : A study to identify and reduce time-consuming activities with focus on the methodology of In-Process Part Definition

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Viktoria Pettersson; Malin Magnusson; [2019]
    Nyckelord :MBD; Design Automation; Time Study; Efficiency; CATIA;

    Sammanfattning : This thesis started as an initiative from one of the co-authors that previously worked at SAAB AB during summer 2018. During the summer she worked with the design process of In-process part Definition (IPPD) and an interest emerged for making it more efficient. LÄS MER

  5. 10. Readjusting Historical Credit Ratings : using Ordered Logistic Regression and Principal ComponentAnalysis

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Axel Cronstedt; Rebecca Andersson; [2018]
    Nyckelord :Ordered Logistic Regression; Principal Component Analysis; MacroEconomic Variables; Credit Risk; Credit Ratings; Multivariate Time SeriesData; Ordinal logistisk regression; Principalkomponentanalys; Makro-ekonomiska variabler; Kreditratings; Multivariata tidsserier;

    Sammanfattning : Readjusting Historical Credit Ratings using Ordered Logistic Re-gression and Principal Component Analysis The introduction of the Basel II Accord as a regulatory document for creditrisk presented new concepts of credit risk management and credit risk mea-surements, such as enabling international banks to use internal estimates ofprobability of default (PD), exposure at default (EAD) and loss given default(LGD). These three measurements is the foundation of the regulatory capitalcalculations and are all in turn based on the bank’s internal credit ratings. LÄS MER
