1. An Integrated Procedure for Tree N-body Simulations: FLY and AstroMD
... We present a new code for evolving three-dimensional self-gravitating collisionless systems with a large number of particles . FLY (Fast Level-based N-bodY code) is a fully parallel code based on a tree algorithm. ... FLY output data can be analysed with AstroMD, an analysis and visualization tool specifically designed for astrophysical data. ... During the tree walk procedure, FLY builds a single interaction list (IL) to be applied to all particles inside a grouping cell ( ). ...

3. Model of clusters
... The most powerful and widely used methods to calculate the scattering matrix of a fractal cluster are based on the coupled dipoles methods (e.g. the Discrete Dipole Approximation, DDA) and the theory of light scattering by a cluster of spherical particles [2-4]. ... At present the procedure of calculation of the scattering matrix is well developed for both an oriented cluster of spherical particles and for chaotically oriented clusters of such particles [4]. ...

We need simple numbering scheme, so that for any given point we could easily calculate the number of "pixel", this is what HealPix provides and lacks HTM. ... During Rtree queries the number of index blocks read is several times greater than during Q3C queries. ... But in Q3C scheme, as we showed before, the circle is segmented, so we extract from the database only a few percents more data than occur in the circle. ...

home . projects . my portfolio . blog . contact . My Ph.D. work was focused mainly on the development of boundary conditions for Smoothed Particle Hydrodynamics simulations of binary stars. ... I developed and tested an innovative way of modeling only the outer parts of stars, therefore allowing for an increased particle and mass resolution in the mass transfer itself. This work was published in Lajoie Sills 2010a (The Astrophysical Journal 726, 66). ...

14. Cluster Analysis
... The routines implemented are CLUSTER which has 8 options for hierarchical clustering and PARTITION which carries out non--hierarchical clustering. ... The former is non--hierarchical clustering or partitioning. The latter is hierarchical clustering. Brief consideration will show that a sequence of n-1 agglomerations are needed to successively merge the two closest objects and/or clusters at each stage, so that we have a set of n (singleton) clusters, n-1 clusters, ..., 2 clusters, 1 cluster. ...
