Grid computing can be defined as coordinated resource sharing and problem solving in dynamic, multiinstitutional collaborations [1]. As more Grids are deployed worldwide, the number of multi-institutional collaborations is rapidly growing. However, for Grid computing to realize its full potential, it is expected that Grid participants are able to use one another resources. Resource negotiation ...

This paper describes a method and system for integrating machine learning with planning and data visualization for the management of mobile sensors for Earth science investigations. Data mining identifies discrepancies between previous observations and predictions made by Earth science models. Locations of these discrepancies become interesting targets for future observations. Such targets beco...

A flow injection analyser has been constructed to allow an operator-free determination of up to 40 samples. Besides the usual FIA apparatus, the analyser includes a home-made sample introduction device made with three electromechanical three-way valves and an auto-sampler from Technicon which has been adapted to be commanded by an external digital signal. The analyser is controlled by a single ...

Novel aluminised E-glass fibre reinforced unsaturated polyester composites, originally formulated for enhanced thermal and electrical shielding properties were evaluated in terms of their thermal performance. The thermal degradation of these specimens was analysed using a thermogravimetric analyser (TGA). The samples were heated from ambient temperature to 500 1C at a heating rate of 20 1C/min....

This article describes the evolution of the design of Vannevar Bush's Memex, tracing its roots in Bush's earlier work with analog computing machines, and his understanding of the technique of associative memory. It argues that Memex was the product of a particular engineering culture, and that the machines that preceded Memex — the Differential Analyzer and the Selector in particular — helped e...

Among several countermeasures suggested for thwarting differential analysis are the random ordering of operations, insertion of random operations, and random insertion of operations. This paper presents a phase-substitution technique which in combination with subsequent time-domain differential analysis is shown to be able to thwart these three countermeasures in several experiments. Unlike pre...

This paper describes an evaluation of newly developed SF-3000 haematology analyser. This instrument is smaller than comparable instruments, and uses a semiconductor laser. Its precision and reproducibility were found to be good. Accurate measurements of the leukocyte differential were obtainedfrom stored blood (kept at room temperature and 4C)for up to 24 hours after collection. A good correlat...

In order to evaluate the Cobas Argos 5 Diff, a five-part differential haematological analyser, we performed a comparative study using our current analyser, the Toa E-5000, and the manual leukocyte differential. Samples (n = 593) were collected from various departments in our hospital and were tested on both Cobas Argos 5 Diff and Toa E-5000. Regression lines were calculated for all standard hae...
