  1. 1. Hur påverkas elevers förståelse för multiplikation av areamodeller som representation? En designstudie i en grekisk grundskola med elever i Åk 2, där undervisningsprocessen fokuserar multiplikativt tänkande samt kommutativa lagen för multiplikation

    Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Antelina Sema; [2024-03-04]
    Nyckelord :Multiplikativt tänkande; Areamodell för multiplikation; Kommutativa lagen; Proportionalitet;

    Sammanfattning : This design study explores the use of the area model as a representation of multiplication, providing opportunities for second school grade pupils to develop an understanding of multiplication and build multiplicative thinking. Furthermore, the study aims to give pupils the opportunity to discover the commutative law of multiplication with the help of the area model. LÄS MER

  3. 2. Boosting Growth in Crisis: Evaluating the Role of Fiscal Stimulus in Sweden’s Pandemic Recovery

    Kandidat-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Lovisa Sundqvist; [2023]
    Nyckelord :Covid-19; fiscal policy; fiscal multipliers; government debt sustainability; debt dynamics; Sweden; Business and Economics;

    Sammanfattning : The Covid-19 crisis presents an opportunity to evaluate the effectiveness of fiscal policy by investigating how fiscal stimuli aided recovery from the pandemic in Sweden. As Covid-19 have led to increased concerns of unsustainable debt levels, questions of how government spending has affected the economic rebound and fiscal sustainability arises. LÄS MER

  4. 3. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Nyckelord :high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Sammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER

  5. 4. Let's get fiscal!

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :David Grahn; Stefania Mammos; [2022]
    Nyckelord :Fiscal policy; zero lower bound; private consumption; durable goods; non-durable goods; government spending; BSVAR; Business and Economics;

    Sammanfattning : This thesis studies the effect on private consumption and its components by durability, following an exogenous shock to government spending, in Denmark and Sweden. In order to compare the outcomes when being at the zero lower bound (ZLB) or not, the quarterly data ranging from 1995 to 2020, is split into two sub-samples. LÄS MER

  7. 5. The Strong Potential of ΛΛ Femtoscopy at HADES

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Kärnfysik

    Författare :Malin Bohman; [2022]
    Nyckelord :hyperon; hyperons; Λ hyperon; ΛΛ; femtoscopy; correlation studies; strong interaction; hyperon interaction; hyperon interactions; HADES;

    Sammanfattning : The aims of this thesis project have been to determine the feasibility of hyperon reconstruction utilizing a newly developed and implemented vertex fitter based on the Lagrange multiplier method. This was achieved through simulation and subsequent analysis of the reaction specified below, detailing the production of Λ-hyperon and K+ -meson pairs from proton-proton collisions. LÄS MER
