Canto: a Hypertext Data Model

The Canto hypertext data model is characterized by a hierarchical schema mechanism that allows a predetermined, open-ended schema to be embedded in the hyperdocument. Canto uses two types of nodes: concept nodes, which provide organizational structure, and information nodes, which contain text and other data. The operations provided by the Canto Data Model are defined formally using the Z speci...

Modelling CDA mass spectra

We present the initial results from a simulation of ion behaviour within Cassini’s cosmic dust analyser (CDA) instrument, using an inhouse ion dynamics code. This work is to enable and enhance the detailed interpretation of dust impact ionisation mass spectra returned from the Saturnian system. Early work has already provided insights into the properties of the impact plasma in both lowand high...

Spatio-Temporal Changes in Structure for a Mediterranean Urban Forest: Santiago, Chile 2002 to 2014

There is little information on how urban forest ecosystems in South America and Mediterranean climates change across both space and time. This study statistically and spatially analyzed the spatio-temporal dynamics of Santiago, Chile’s urban forest using tree and plot-level data from permanent plots from 2002 to 2014. We found mortality, ingrowth, and tree cover remained stable over the analysi...

Cda Loop Transformations

In this paper we present a new loop transformation technique called Computation Decomposition and Alignment (CDA). Computation Decomposition rst decomposes the iteration space into ner computation spaces. Computation Alignment subsequently, linearly transforms each computation space independently. CDA is a general framework in that linear transformations and its recent extensions are just speci...
