  2. 21. A Theoretical Study of Carbon Nanotubes in Electronic Packaging Applications

    Author : Zhili Hu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; simulation; thermal interface material; continuum; electronic packaging; MDs; CNT;

    Abstract : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. READ MORE

  4. 22. Selected Topics in Continuum Percolation : Phase Transitions, Cover Times and Random Fractals

    Author : Filipe Mussini; Erik I. Broman; Hermine Biermé; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson point process; Percolation; Boolean model; Quasi-isometries; Cover times; Poisson cylinder process; Ellipsoid process; Phase transition; Random fractals; Mathematics; Matematik;

    Abstract : This thesis consists of an introduction and three research papers. The subject is probability theory and in particular concerns the topics of percolation, cover times and random fractals.Paper I deals with the Poisson Boolean model in locally compact Polish metric spaces. READ MORE

  6. 24. Continuum modeling of paperboard for the mechanical response of converting processes

    Author : Kristofer Robertsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Continuum modeling; Converting processes; FEM simulations; Finite strain theory; Damage modeling; Rate-dependent; Creasing and folding; Out-of-plane experiments;

    Abstract : Paperboard is a thin and lightweight material made of cellulose fibers and it is an important component in packaging material where it provides stiffness and rigidity. The scope of this work is the development of continuum models, and its numerical treatments, for simulating the processes of converting paperboard into packages. READ MORE

  7. 25. A multiwavelength approach to solar chromospheric heating : New insights from the millimeter continuum

    Author : João Manuel da Silva Santos; Jaime de le Cruz Rodríguez; Jorrit Leenaarts; Petr Heinzel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; chromosphere; radiative transfer; waves; reconnection; Astronomy; astronomi;

    Abstract : The chromosphere is an intermediate layer of the Sun's atmosphere where radiative equilibrium breaks down. The standard chromospheric diagnostics such as the Mg II h and k and Ca II H and K spectral lines are formed under nonlocal thermodynamic equilibrium (NLTE) and they are only partially sensitive to the local conditions.
