  4. 23. Polymer and Protein Physics : Simulations of Interactions and Dynamics

    Författare :Anna Sinelnikova; Johan Nilsson; Carl Caleman; Erik Lindahl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymers; proteins; Monte Carlo; molecular dynamics; phase diagram; renormalisation group; SPI; polymer effective model; coarse-graining; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. LÄS MER

  5. 24. A Ventilation Strategy Based on Confluent Jets : An Experimental and Numerical Study

    Författare :Setareh Janbakhsh; Bahram Moshfegh; Alexander Zhivov; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple interacting jets; round jets; confluent jets; wall jet; ventilation strategy; air distribution system; air supply device; ventilation performance; thermal comfort; energy-saving potential; measurement; numerical predictions; RANS turbulence models; renormalization group RNG k– ε ; realizable Re k– ε ; and shear stress transport SST k– ω ;

    Sammanfattning : This study presents air distribution systems that are based on confluent jets; this system can be of interest for the establishment of indoor environments, to fulfill the goals of indoor climate and energy-efficient usage. The main objective of this study is to provide deeper understanding of the flow field development of a supply device that is designed based on wall confluent jets and to investigate the ventilation performance by experimental and numerical methods.

  7. 25. On transport theory of correlated mesoscopic systems

    Författare :Vadim Cheianov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Teoretisk fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : This thesis is about the theory of quantum transport through low dimensional correlated systems. Correlated systems are interacting many-particle systems where collective effects predominate over the individual properties of particles whereof they consist. Single particle approach to correlated systems would be essentially wrong. LÄS MER
