Dynamic process management is a much-needed feature for applications and tools development in Beowulf cluster environment. A welldefined and efficient dynamic process management in cluster middleware layer can simplify the programming task of parallel tool developers. This paper presents the design and implementation of dynamic process management in a cluster middleware called KSIX. KSIX provid...

The objective of this paper is to define a decision support system over SOX (Sarbanes-Oxley Act) compatibility and quality of the Suppliers Selection Process based onArtificial Intelligence andArgumentationTheory knowledge and techniques.The present SOX Law, in effect nowadays, was created to improve financial government control over US companies. This law is a factor standard out United States...

Temporary streams represent a significant yet understudied and particularly vulnerable portion of river networks. While the vast majority of stream and river research to date has focused on perennial flowing waters, recent work reveals that temporary streams are not only abundant and widely distributed, but also play a significant role in the hydrological and ecological integrity of lotic netwo...

Efforts to restore ecosystems often focus on reintroducing apex predators to re-establish coevolved relationships among predators, herbivores and plants. The preponderance of evidence for indirect effects of predators on terrestrial plant communities comes from ecosystems where predators have been removed. Far less is known about the consequences of their restoration. The effects of removal and...

Background An underperforming doctor puts patient safety at risk. Remediation is an intervention intended to address underperformance and return a safe practice. Used in health-care systems all over the world, it has clear implications for both retention workforce. However, there limited evidence underpinning remediation programmes, particularly lack of knowledge as why how remedial may work ch...

[1] We have developed a novel method for delineating valley networks on Mars. The valleys are inferred from digital topography by an autonomous computer algorithm as drainage networks, instead of being manually mapped from images. Individual drainage basins are precisely defined and reconstructed to restore flow continuity disrupted by craters. Drainage networks are extracted from their underly...

Entropy coded multimedia signals such as JPEG and MPEG-1 and 2 have little or no error resiliency. To counter this situation, researchers have proposed using reversible VLCs (RVLC) to identify and limit error propagation. To bring error resiliency to Huffman-coded streams, a bidirectionally decodable packet has been introduced. This packet can be decoded in both directions to trap corrupted VLC...

Temporary streams in California and other Mediterranean climate areas are among the aquatic habitats most altered by human actions and invasions of alien species. They typically support novel ecosystems, defined as ecosystems dominated by new combinations of organisms in highly altered habitats. While these new ecosystems have many attributes of ecosystems they replaced, often including native ...

Vacuum-enhanced direct contact membrane distillation (VEDCMD) and forward osmosis (FO) were investigated for water recovery enhancement in desalination of brackish water. Past studies have demonstrated that both VEDCMD and FO can be effectively utilized in the treatment of a wide range of highly concentrated feed solutions. In the current study, two reverse osmosis (RO) brine streams with total...

Quantum mechanic~ without the collapse postulate, the ~ theory, wa.~ proposed by Alben (1992) as a way of understanding Everett's relative-state fonnulation of quantum mechanics. The basic idea is to try to account for an observer's beliefs by appealing to a type of illusion predicted by the bare dteory. This paper respond~ to some recent objections to the bare thet)ry by providing a more detai...
