2. 1. Quantum theory of time-dependent transport in graphene

   Author : Yevgeniy Korniyenko; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; graphene; ballistic quantum transport; Landauer-Büttiker theory; Fano resonance; Floquet scattering matrix;

   Abstract : High-quality ballistic electronic devices made from graphene are becoming an experimental reality. Carbon-based electronics is heralded if not to succeed or surpass then to complement the existing semiconducting technology. READ MORE

4. 2. Human brains and virtual realities : Computer-generated presence in theory and practice

   Author : Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; Giuseppe Riva; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human brain function; virtual reality; presence; cognitive neuroscience; human-computer interaction; brain imaging; fMRI; BCI; neural correlates; HCI theory; reality-based interaction.;

   Abstract : A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable.

5. 3. Statistical modelling in chemistry - applications to nuclear magnetic resonance and polymerase chain reaction

   Author : Halfdan Grage; Teknisk mikrobiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; operationsanalys; programmering; aktuariematematik; programming; actuarial mathematics; Statistics; operations research; experimental design.; logistic regression; detection probability; region of operability; sampling. Diagnostic PCR; Cramér-Rao bounds; maximum likelihood estimation; NMR spectroscopy; Gaussian noise;

   Abstract : This thesis consists of two parts with the common theme of statistical modelling in chemistry. The first part is concerned with applications in nuclear magnetic resonance (NMR) spectroscopy, while the second part deals with applications in polymerase chain reaction (PCR). READ MORE

6. 4. Rotational Resonance in the Nuclear Magnetic Resonance of solids

   Author : Torgny Karlsson; S Vega; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; fysikalisk kemi;

   Abstract : This thesis presents new physical phenomena in the rotational resonance NMR of magic-angle spinning solids. The theory of a new class of nuclear spin echoes is developed. READ MORE

7. 5. Ferromagnetic resonance in films with growth induced anisotropy

   Author : Sergey Manuilov; Alex Grishin; Boris Kalinikos; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferromagnetic resonance; magnetic anisotropy; single-ion anisotropy model; ferrites; magnetic epitaxial films; magnetostatic waves; pulsed laser deposition; magnetic alloys; domains; domain wall transformations;

   Abstract : This thesis discusses two different magnetic materials: epitaxial yttrium iron garnet (YIG) and heteromorphous CoFeB-SiO2 films. YIG films were grown by pulse laser deposition (PLD) techniques onto gadolinium gallium garnet (GGG) substrates of (111) and (001) crystal orientations. READ MORE
