2. 1. Mesoscopic superconductivity : quasiclassical approach

   Author : Marek Ožana; Andrei Shelankov; Dierk Rainer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoscopic superconductivity; quasiclassical theory; boundary conditions; multi-layer structures; Gor kov equations; quasiclassical Green s function; Green s function on classical trajectories;

   Abstract : This Thesis is concerned with the quasiclassical theory of meso-scopic superconductivity. The aim of the Thesis is to introduce the boundary conditions for a quasiclassical Green’s function on partially transparent interfaces in mesoscopic superconducting structures and to analyze the range of applicability of the quasiclassical theory.

4. 2. On the nature of self-assembly in low-density condensed matter : A classical molecular dynamics approach

   Author : Alfredo Metere; Peter Oleynikov; Anatoly Belonoshko; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fysikalisk kemi; Physical Chemistry;

   Abstract : The study of the physics of self-assembly in low-density condensed matter is an extremely interesting, mostly unexplored field of scientific research. The contribution reported in this thesis explains how this problem can be addressed using molecular dynamics simulation of 3D systems composed by simple, identical particles, interacting via a spherically symmetric pair potential, which belongs to the class of Dzugutov potentials.

5. 3. Time-domain Reconstruction Methods for Ultrasonic Array Imaging : A Statistical Approach

   Author : Fredrik Lingvall; Tadeusz Stepinski; Karl-Jörg Langenberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Ultrasonic array imaging; synthetic aperture imaging; maximum a posteriori estimation; linear minimum mean squared error estimation; SAFT; Bayesian image reconstruction; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

   Abstract : This thesis is concerned with reconstruction techniques for ultrasonic array imaging based on a statistical approach. The reconstruction problem is posed as the estimation of an image consisting of scattering strengths. READ MORE

6. 4. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

   Author : Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

   Abstract : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. READ MORE

7. 5. Avian MHC : Characterization and expression patterns of classical and non-classical MHC-I genes

   Author : Anna Drews; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MCH class I; Classical genes; Non-classical genes; Expression; Passerine birds;

   Abstract : The function of the vertebrate immune system is to enable recognition and elimination of microorganisms that can cause harm (pathogens). A key component in adaptive immunity is the major histocompatibility complex (MHC) that codes for molecules with antigen presentation function. READ MORE
