Grid computing can be considered large-scale distributed cluster and parallel network processing. The two most important issues in managing user work are resource allocation scheduling of required resources. When jobs submitted, they managed by intermediaries who find allocate the right After stage, scheduled on existing resources according to user's In grid systems with traditional scheduling,...

A spectroscopic analysis of the DAB white dwarf PG 1115+166 is presented. The observed hydrogen and helium line profiles are shown to be incompatible with model spectra calculated under the assumption of homogeneous or stratified chemical compositions. In contrast, an excellent fit to the optical spectrum of PG 1115+166 can be achieved if the object is interpreted as an unresolved double degene...

Motivated by the finding that the observed surface brightness profile of many galactic nuclei are well fit by double-power-laws, we explore a range of spherical self-consistent dynamical models with this light profile. We find that the corresponding deprojected volume density profile, phase space density and line-of-sight velocity distribution of these models are well fit by simple analytic app...

Bosek and Krawczyk exhibited an on-line algorithm for partitioning an on-line poset of width w into w lgw chains. They also observed that the problem of on-line chain partitioning of general posets of width w could be reduced to First-Fit chain partitioning of (2w + 1)-ladder-free posets of width w, where an m-ladder is the transitive closure of the union of two incomparable chains x1 6 . . . 6...

The broad Iron line in MCG-6-30-15 is fitted to the Comptonization model where line broadening occurs due to Compton down-scattering in a highly ionized optically thick cloud. These results are compared to the disk line model where the broadening is due to Gravitational/Doppler effects in the vicinity of a black hole. We find that both models fit the data well and it is not possible to differen...

A method is described for segmenting edge data into a combination of stmight lines and elliptic am. The westage process first segments the data into straight line segments. Ellipses are then fitted to the line data. ntis is much fmter than curve fitting directly topire1 data since the lines provide a great reduction in data. Segmentation is pegormed in the paradigm suwsted by Lowe [5]. A measur...

Decisions are often based on the results of quantitative analysis. To gain confidence in these results, some indication of their quality is needed. Measurement uncertainty, as proposed by the International Organization for Standardization (ISO), is a way to express this quality. Most measurement techniques compare references and therefore need to be calibrated. Usually least squares methods ign...

ER (Extended R-squared) is proposed as a similarity measure for on-line signature verification. SLR (Simple Linear Regression) defines R as a measure of goodnessof-fit. We observed that R is a good similarity measure for 1-dimensional sequences. However, many kinds of sequences are multidimensional, such as on-line signature sequences, 2D curves, etc. Therefore, we extend R to ER for multidimen...

We investigate the ability of both LTE and Non-LTE models to fit the near UV band absolute flux distribution, fλ(λ), and individual spectral line profiles of three standard stars for which high quality spectrophotometry and high resolution spectroscopy are available: The Sun (G2 V), Arcturus (K2 III), and Procyon (F5 IV-V). We investigate 1) the effect of the choice of atomic line list on the a...
