This paper describes a system for rendering large (billions of points) point clouds using a strict level-ofdetail criterion for managing the data out of core. The system is comprised of an in-core data structure for managing the coarse hierarchy, an out-of-core structure for managing the actual data and a multithreaded rendering framework that handles the structure and is responsible for data c...

This paper describes a new out-of-core multi-resolution data structure for real-time visualization and interactive editing of large point clouds. In addition, an editing system is discussed that makes use of the novel data structure to provide interactive editing tools for large scanner data sets. The new data structure provides efficient rendering and allows for handling very large data sets u...

Classification is an important problem in the field of data mining. Construction of good classifiers is computationally intensive and offers plenty of scope for parallelization. Divide-and-conquer paradigm can be used to efficiently construct decision tree classifiers. We discuss in detail various techniques for parallel divide-and-conquer and extend these techniques to handle efficiently disk-...

the formation of atoll garnet in the ardara aureole, nw ireland, is discussed using the textural, chemical and electron backscatter diffraction (ebsd) data. textural evidence suggests the possibility of incipient of garnet replacement from the core. in addition, the presence of staurolite and andalusite in the core of small atoll garnets as well as the occurrence of sillimanite in the core of l...

The Dublin Core Metadata Initiative (DCMI) maintains a vocabulary of several dozen metadata terms, most notably the fifteen-element Dublin Core. Within DCMI, however, discussion has focused more on the practices, policies, and models around the Core. Its initial single-resource data model is evolving towards a fuller framework for evaluating the diversity of Dublin Core implementations. Terms (...

Multimedia documents are more and more expressed in XML as data representation and exchange services. In this paper, we describe the data and execution models of XML Multimedia Document management as a part of the PHASME information engine. The core data model exploits the Extended Binary Graph structure (so called EBG structure); we present the storage and indexing services. The goals of the o...

The traditional dialect vocabulary of the Netherlands and Flanders is recorded and researched in several Dutch and Belgian research institutes and universities. Most of these distributed dictionary creation and research projects collaborate in the “Permanent Overlegorgaan Regionale Woordenboeken” (ReWo). In the project “digital databases and digital tools for WBD and WLD” (D-square) the dialect...
