   abstract = {The purpose of this study was to develop and apply a quantitative optical
      method suitable for routine measurements of biofilm structures under in situ
      conditions. A computer program was designed to perform automated investigations
      of biofilms by using image acquisition and image analysis techniques. To obtain
      a representative profile of a growing biofilm, a nondestructive procedure was
      created to study and quantify undisturbed microbial populations within the
      physical environment of a glass flow cell. Key components of the
      computer-controlled processing described in this paper are the on-line
      collection of confocal two-dimensional (2D) cross-sectional images from a
      preset 3D domain of interest followed by the off-line analysis of these 2D
      images. With the quantitative extraction of information contained in each
      image, a three-dimensional reconstruction of the principal biological events
      can be achieved. The program is convenient to handle and was generated to
      determine biovolumes and thus facilitate the examination of dynamic processes
      within biofilms. In the present study, Pseudomonas fluorescens or a green
      fluorescent protein-expressing Escherichia coli strain, EC12, was inoculated
      into glass flow cells and the respective monoculture biofilms were analyzed in
      three dimensions. In this paper we describe a method for the routine
      measurements of biofilms by using automated image acquisition and semiautomated
      image analysis.},

   abstract = {In scientific computing, efficient discretization technqiues are of crucial
      importance. While a sophisticated a priori choice of grid patterns has a quite
      long tradition for the approximation, interpolation, and integration of
      functions, the hierarchical sparse grid concept was the first approach to
      combine such structural considerations with adaptive finite element
      discretizations for partial differential equations. The most important property
      of sparse grids is certainly the fact that the number of degrees of freedom
      necessary to achieve a certain given accuracy does not depend or depends only
      on very slightly on the problem's dimensionality d, which is advantageous
      especially for problems with large d.
      
      In this text, we deal with both the theoretical and the algorithmic extension
      of the piecewise linear approach used so far to polynomial bases odf an
      arbitrary and varying degree. The construction of suitable hierarchical bases
      with just one degree of freedom per element and the generalization of the
      unidirectional sparse grid algorithms allow to combine the optimal complexity
      of the sparse grid approach with the advantages of both adaptive mesh
      refinement and higher order approximation.},
