  1. 21. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    Författare :Mathias Agmell; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

    Sammanfattning : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. LÄS MER

  3. 22. Quantum Wavepacket Dynamics in Molecular and Trapped Ion Systems

    Författare :Dong Wang; Tony Hansson; Volker Engel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wavepacket; revival; anisotropy; polarization; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Sammanfattning : The motions of a wavepacket in the two coupled potentials studied in this thesis can be classified into either bistable or astable motion according to the wavepacket interference at the curve crossing. Bistable motion, in which the wavepacket performs a coupled oscillation but remains in the same adiabatic and diabatic state, can exist both in bound-bound systems and bound-unbound ones with long time stability.

  4. 23. Studies on myocardial regeneration

    Författare :Olaf Ingmar Bergmann; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Heart disease is one of the leading causes of adult and child morbidity and mortality. The underlying pathology leads typically to a loss of functional cardiomyocytes that causes heart failure. LÄS MER

  5. 24. The Burning Word : History and Myth in Maximilian Voloshin's Neopalimaia Kupina 

    Författare :Emma-Lina Löflund; Anna Ljunggren; Julie Hansen; Olga Peters Hasty; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Maximilian Voloshin; Russian Symbolism; poetry; Russian Revolution; neomythological texts; performativity; anthroposophy; Rudolf Steiner; theurgy; life-creation; myth-creation; semiotics; slaviska språk; Slavic Languages;

    Sammanfattning : The book Neopalimaia Kupina: stikhi o voine i revoliutsii (The Burning Bush: Poems about War and Revolution) by Maximilian Voloshin (1877–1932) depicts the revolutionary period in Russia. This dissertation analyzes the work’s composition, showing how it was shaped and reshaped in response to the dramatic events of the first two and a half decades of the twentieth century, and how it remains open and mirrors the ongoing development of history.

  7. 25. On Mathematical Reasoning : being told or finding out

    Författare :Mathias Norqvist; Johan Lithner; Bert Jonsson; Catarina Rudälv; Kristina Juter; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; creative reasoning; reasoning; cognitive proficiency; fMRI; didactics of mathematics; matematikdidaktik;

    Sammanfattning : School-mathematics has been shown to mainly comprise rote-learning of procedures where the considerations of intrinsic mathematical properties are scarce. At the same time theories and syllabi emphasize competencies like problem solving and reasoning. LÄS MER
