Multidimensional cyclic graph approach: Representing a data cube without common sub-graphs

Joubert de Castro Lima, Celso Massaki Hirata
2011 Information Sciences  
A data cube has base cells and aggregate cells. A cell in a base cuboid is a base cell. A cell in a non-base cuboid is an aggregate cell.  ...  The MCG differs significantly from previous approaches as it completely eliminates prefix and suffix redundancies from a data cube. A data cube can be viewed as a set of sub-graphs.  ...  The adoption of cube shell fragments, proposed in [17] , in conjunction with our idea can produce an efficient MCG approach for high dimensional data cubes, but the row-based idea needs to be reformulated  ...

2021 arXiv   pre-print
We identified 14 filaments (24 in total, including sub-filaments) from the C^18O (1-0) data cube and 22 dense cores from the N_2H^+ (1-0) data.  ...  We present the results on the physical properties of filaments and dense cores in IC 5146, as a part of the TRAO FUNS project.  ...  The filfinder uses 2-dimensional image data and is not suitable for the identification of the filaments in a 3-dimensional data cube.  ...

On Filaments within Molecular Clouds and their Connection to Star Formation [article]

Roxana-Adela Chira
2018 arXiv   pre-print
I conclude that there is no single quantity in my analysis that can uniquely trace the inclination and 3D structure of a filament based on dust observations alone.  ...  In recent years, there were studies on the omnipresence and structures of filaments in star-forming regions, and the role of their fragmentation in the process of star formation.  ...  However, often this comparison cannot occur on a one-to-one basis as observations preliminarily show the two-dimensional (2D) projection of the three-dimensional (3D) objects.  ...

Exploiting programmable graphics hardware for interactive visualization of 3D data fields [article]

Thomas Klein, Universität Stuttgart, Universität Stuttgart
2009
Modern numerical simulation and data acquisition techniques create a multitude of different data fields.  ...  application of graphics hardware in all stages of the visualization pipeline has become a central theme in order to cope with the challenges of data set sizes growing at an ever increasing pace and advancing  ...  Similar to Marching Cubes the basic algorithm processes one grid cell after the other.  ...

2018
I conclude that there is no single quantity in my analysis that can uniquely trace the inclination and 3D structure of a filament based on dust observations alone.  ...  I address the early evolution of pc-scale filaments that form within individual clouds and focus on the questions how and when the filaments fragment, and how the fragmentation relates to typically used  ...  However, often this comparison cannot occur on a one-to-one basis as observations preliminarily show the two-dimensional (2D) projection of the three-dimensional (3D) objects.  ...

Electrospray ion beam deposition and mass spectrometry of nonvolatile molecules and nanomaterials

Stephan Rauschenbach
2007
BSA forms fractal agglomerations on graphite, while it does not show any diffusion on SiO x surfaces. SDS forms flat, two dimensional islands on graphite and silicon.  ...  The ion beam is sampled from a supersonic expansion by a skimmer, collimated in a high pressure quadrupole ion guide, mass selected in a low pressure quadrupole ion guide and focused by electrostatic lenses  ...  Considering the fact that those are one dimensional particles, a high value has to be expected, since an elongated object can carry more charges compared to a globular one with the same volume.  ...
