1. 1. Tidig aritmetisk kunskapsbildning : Ett radikalkonstruktivistiskt perspektiv

   Författare :Göta Eriksson; Siv Fischbein; Olof Magne; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Radical Constructivism; model building; ontogenesis of arithmetic; counting scheme; cognitive system of self-regulation and self-organising; conceptual progression; longitudinal approach; special education.; Education; Pedagogik;

   Sammanfattning : From a Radical Constructivist (RC) perspective this thesis deals with children’s construction of early arithmetic learning as an evolving process through the cognitive system of self-regulation and self-organising. Thus the child’s learning must guide teaching. RC views early arithmetic as verbal and preceding the system of written arithmetic. LÄS MER

3. 2. Cluster Effective Field Theory

   Författare :EMIL RYBERG; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

   Sammanfattning : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. LÄS MER

4. 3. Compact orientation and frequency estimation with applications in biometrics : Biometrics on the orientation express

   Författare :Anna Mikaelyan; Josef Bigun; Kenneth Nilsson; Raffaele Cappelli; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Automatic feature extraction still remains a relevant image and signal processing problem even tough both the field and technologies are developing rapidly. Images of low quality, where it is extremely difficult to reliably process image information automatically, are of special interest. LÄS MER

5. 4. Theoretical Studies of Hadronic Reactions with Vector Mesons

   Författare :Carla Terschlüsen; Stefan Leupold; Stefan Scherer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Vector mesons; Effective field theories; Chiral Lagrangian; Meson-meson interactionss; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Sammanfattning : Aiming at a systematic inclusion of pseudoscalar and vector mesons as active degrees of freedom in an effective Lagrangian, studies have been performed in this thesis concerning the foundations of such an effective Lagrangian as well as tree-level and beyond-tree-level calculations. Hereby, vector mesons are described by antisymmetric tensor fields. LÄS MER

7. 5. Creation and Detection of Single Photons

   Författare :Hatim Azzouz; Mohamed Bourennane; Sergey Cherednichenko; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : A growing number of technologies employ quantum properties in order to produce solutions that surpass the performance of conventional devices, or to execute operations that are fundamentally impossible with classical systems alone. In the field of optical quantum information science, photons are utilized to encode, communicate and manipulate information, making them vitally important. LÄS MER
