Computational science research components were vital parts of the SciDAC1 accelerator project and are continuing to play a critical role in newly-funded SciDAC-2 accelerator project, the Community Petascale Project for Accelerator Science and Simulation (ComPASS). Recent advances and achievements in the area of computational science research in support of petascale electromagnetic modeling for ...

During the ERP system design process, various risks have potential to disrupt and hinder implementation project. This paper presents stages of risk analysis using HoR (House Risk) approach. The author uses project manager as an expert in field implementation. has prioritized three causes with proposed mitigation actions. for implementor perspective are (1) learning independently a action agains...

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for 14 close binary stars, S Ant, TT Cet, TW Cet, AA Cet, RW Dor, UX Eri, YY Eri, BV Eri, CT Eri, SZ Hor, AD Phe, TY Pup, HI Pup and TZ Pyx. All are double-lined binaries and all except the last one are contact binaries. The orbital data must be considered preliminary because of the relatively smal...

The hard square model consists of all binary arrays in which the s are isolated both hor izontally and vertically Based on a certain proba bility measure de ned on those arrays an e cient variable to xed rate encoder scheme is obtained that maps unconstrained binary words into arrays that sat isfy the hard square model For su ciently large ar rays the average rate of the encoder approaches a va...
