... 2002 September 27 . Accretion Disk Simulation . ... The graceful spiral structure seen in this computer visualization does not portray winding spiral arms in a distant galaxy of stars . Instead, the graphic shows spiral shock waves in a three dimensional simulation of an accretion disk -- material swirling onto a compact central object that could represent a white dwarf star , neutron star , or black hole . Such accretion disks power bright x-ray sources within our own galaxy. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

Random Numbers 7.0 Introduction It may seem perverse to use a computer, that most precise and deterministic of all machines conceived by the human mind, to produce "random" numbers. ... Nevertheless, practical computer "random number generators" are in common use. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

To claim results are powerful statistically, astronomers highly rely on eyeballing techniques (need apprenticeship to acquire skills but look subjective to me without such training). ... One thing I want to point out is the phrase ?statistically powerful method? (in the context that they preform statistical data analysis, claimed to be a powerful method) which often misguides me because I cannot find a powerful test statistic in their studies. ...

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms. I am particularly interested in the stability properties of accretion discs, the generation of MHD turbulence and associated angular momentum transport, disk - planet interactions and the origin and characteristics of jets and winds from accreting systems . ... These results have been published in Salmeron & Wardle, 2005, M.N.R.A.S., 361: 45-69. ...

... This paper describes our GAMMS (Gravitational Adaptive Mesh Multigrid Solver) code, which is a numerical gravitational solver, based upon a multigrid (MG) algorithm and a local refining mesh strategy (AMR, Adaptive Mesh Refinement). ... Inside our GAMMS code, each adaptive mesh is built and controlled using the DAGH (Distributed Adaptive Grid Hierarchy) library (see http://www.caip.rutgers.edu/ ~ parashar/DAGH ). ... Tests on our AMR code show that it can efficiently handle an adaptive mesh. ...
