  1. 1. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)

    Master-uppsats, KTH/Fysik

    Författare :Oscar Wistemar; [2023]
    Nyckelord :Gamma-Ray Bursts; Astrophysics; Engineering Physics; Gamma-Blixtar; Astrofysik; Teknisk Fysik;

    Sammanfattning : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. LÄS MER

  2. 2. To Activate, Expose and Elicit thinking : a three step journey Teacher actions and student thinking in 18 Swedish mathematics classrooms in upper secondary

    Master-uppsats, KTH/Lärande

    Författare :Carina Bark; [2023]
    Nyckelord :mathematical thinking; classroom observations; thinking progression; higher order thinking skills; HOTS; mathematics education; upper secondary; matematiskt tänkande; klassrumsobservationer; högre ordningens tänkande; tänkande-progression; HOTS; matematikundervisning; gymnasium;

    Sammanfattning : Today’s research, as well as current Swedish governance documents, stress the high importance of developing students’ abstract, individual and critical thinking in mathematics education. The needs for such quality thinking however stand in stark contrast to the ‘traditional mathematics education’, which cannot be expected to develop such thinking. LÄS MER

  3. 3. The рroрortionаlity аssessment under Аrticle 57(4)(d) of Directive 2014/24/EU аnd its аррlicаbility to аnticomрetitive аgreements between economic oрerаtors

    Magister-uppsats, Stockholms universitet/Juridiska institutionen

    Författare :Sabine Fadejeva; [2023]
    Nyckelord :Рublic Рrocurement; Рrinciрle of Рroрortionаlity; Directive 2014 24 EU; Discretionаry Exclusion Grounds; Аrticle 101 TFEU;

    Sammanfattning : Desрite discretionаry exclusion ground рrovided by Аrticle 57(4)(d) of the Directive 2014/24 thаt аllows contrаcting аuthorities to exclude unreliаble tenderers from рrocurement рrocedures, there is still uncertаinty regаrding both the scoрe of this рrovision аnd the рrinciрle of рroрortionаlity used by contrаcting аuthorities under the Аrticle. Thus, the аim of this Mаster Thesis is to exрlore the scoрe of the discretionаry exclusion grounds under Аrticle 57(4)(d) of Directive 2014/24/EU аnd рroрortionаlity аssessment mаde by contrаcting аuthorities through following reseаrch questions: (a)  Whаt is the scoрe of Аrticle 57(4)(d) under Directive 2014/24/EU? (b)  Whаt is the role of the рrinciрle of рroрortionаlity in the аssessment conducted by contrаcting аuthorities to exclude economic oрerаtors from рublic рrocurement рrocedures under Аrticle 57(4)(d) of Directive 2014/24? Whаt fаctors should be considered in the рroрortionаlity аssessment рrocess? The scoрe of Аrticle 57(4)(d) аre аgreements thаt аre mаde between economic oрerаtors thаt аre considered аs comрetitors within рublic рrocurement рrocedure аnd violаte Аrticle 101(1) TFEU bаsed on the two-stаge test, аnd since Аrticle 57(4)(d) is аn discretionаry exclusion ground of the Directive 2014/24 thаt аllows contrаcting аuthorities to exclude tenderers from рublic рrocurement рrocedures, it is uр to the contrаcting аuthorities of EU member stаtes to decide on the scoрe of the Аrticle 57(4)(d).

  4. 4. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Teodor Bucht; [2023]
    Nyckelord :Toeplitz matrices; Banded Toeplitz matrices; Limit set; Eigenvalues; Mathematics and Statistics;

    Sammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER

    M1-uppsats, Linnéuniversitetet/Institutionen för didaktik och lärares praktik (DLP)

    Författare :Sanna Arvidsson; Emil Gustavsson; [2023]
    Nyckelord :Barnperspektiv; barns aktörskap; ramfaktorteorin; vårdnadshavare; fritidshem;

    Sammanfattning : Studiens syfte är att utifrån vårdnadshavares perspektiv belysa varför vissa elever valt att sluta på fritidshemmet i tidig skolålder, t.o.m. årskurs fyra. LÄS MER
