accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...
We propose an analytical model that quantifies the overall execution time of a parallel region in the presence of non-deterministic load imbalance introduced by network contention and by random replacement policy in processor caches. We present a novel model that evaluates the expected hit ratio and variance introduced by a cache accessed with a cyclic access stream. We also model the performan...
The National Oceanic and Atmospheric Administration (NOAA) is currently developing and testing weather models on various parallel computers in order to ascertain their relative eeciency for code development, performance and ultimate production use. As part of that eeort we have ported a simple \Well-Posed Topographical" Meteorological Model to the Kendall Square Research (KSR) parallel supercom...
The purpose of this research is to describe, identify and analyze students' spatial intelligence in working on geometry problems according Van Hiele's theory. method used descriptive with a qualitative approach. This was conducted at SMP Negeri 2 Tarakan. instrument the Hiele geometric thinking level test ability test, interview guides documentation. Prior use, an guide, first validated. data a...
Program transformations and algorithm modiications are discussed that reduce execution time for iterative methods for solving partial diierential equations on high-performance computers. Techniques typically associated with parallel computers turn out to be essential to obtain optimal performance on current superscalar uniprocessors. The tested programs were written in Fortran77 and run on a si...
We describe evidence that a regulatory B subunit of protein phosphatase 2A (PP2A) positively regulates an RTK-Ras-MAP kinase signaling cascade during Caenorhabditis elegans vulval induction. Although reduction of sur-6 PP2A-B function causes few vulval induction defects in an otherwise wild-type background, sur-6 PP2A-B mutations suppress the Multivulva phenotype of an activated ras mutation an...
a linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in sar-cheshmeh copper mine, kerman, iran. a single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. the generated vibrations were measur...
The molecular status of nine species of the genus Alburnoides from different river drainages in Iran and additionally by seven species from Europe was assessed. mtDNA COI gene sequences from freshly collected specimens and available NCBI data revealed four major phylogenetic lineages. Based on the results, a distinct taxon from the Cheshmeh Ali (Ali Spring), a Damghan River tributary in the end...
