The alternating direction implicit (ADI) method is an attractive option to use in avoiding the CourantFriedrichs-Lewy (CFL) condition that limits the size of the time step required by explicit finite-difference time-domain (FDTD) methods for stability. Implicit methods like Crank-Nicholson offer the same advantages as ADI methods but they do not rely on simple, one-dimensional, tridiagonal syst...

â â  in this research, temporal and spatial behavior of subtropical high pressure was studied at the level of 600 hpa. this study has been done using daily data of geopotential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the m...

Imaging at 1.25 and 2.20 mm has been obtained of the field containing the galaxy (RD1) found at redshift by Dey et al. This galaxy has been detected at 1.25 mm, while the lower redshift ( ) galaxy z 5 5.34 z 5 4.02 also found in the same field by Dey et al. was detected at both 1.25 and 2.20 mm. Comparison to stellar population synthesis models indicates that if RD1 is a young ( yr) galaxy, sig...

Earth's energy imbalance (EEI) drives the ongoing global warming and can best be assessed across the historical record (that is, since 1960) from ocean heat content (OHC) changes. An accurate assessment of OHC is a challenge, mainly because of insufficient and irregular data coverage. We provide updated OHC estimates with the goal of minimizing associated sampling error. We performed a subsampl...

This paper presents an extension to the W3C PROV provenance model, aimed at representing process structure. Although the modelling of process structure is out of the scope of the PROV specification, it is beneficial when capturing and analysing the provenance of data that is produced by programs or other formally encoded processes. In the paper, we motivate the need for such extended model in t...

We challenge the standard argument whach treats collective violence as an expression of the dissatisfactions felt by populations experiencing hardship after periods of relative well-being. We propose an alternative explanation in which struggles for political power are the central features. Tfme-series analysis of year-to-year fluctuations of collective violence in France from 1830 through 1960...

us (Dey, 1930 and FitzGerald and Dey, 1931), but the primary lesion, when discovered, is remarkably constant. It seems therefore of interest to record two types, which, whilst they have been previously described, are undoubtedly of great clinical rarity. I.
