In 1999, AT&T participated in the ad-hoc task and the Question Answering (QA), Spoken Document Retrieval (SDR), and Web tracks. Most of our eeort for TREC-8 focused on the QA and SDR tracks. Results from SDR track show that our document expansion techniques, presented in 8, 9], are very eeective for speech retrieval. The results for question answering are also encouraging. Our system designed i...

Physically-based, fully-distributed hydrologic models simulate hydrologic state variables in space and time while using information regarding heterogeneity in climate, land use, topography and hydrogeology. Since fine spatio-temporal resolution and increased process dimension will have large data requirements, there is a practical need to strike a balance between descriptive detail and computat...

In this paper, we seek to design, develop, and explore a typical geo-database for hydrographic purposes through the aid of some Open-Source Geographical Information System (GIS) and relational database packages that had been confirmed and certified to be adequate for various GIS tasks. One of the recent and reliable OpenSource software in GIS analysis is gvSIG. gvSIG is a tool oriented to manag...

The utilization of urban green zones forms a major part of urban sustainability in the context of the improvement of quality of life of the citizens. Within the policy for sustainable management of urban green zones, the tools that are used effectively are new technologies such as web databases, web DSS, GIS and environmental impact prediction model. This paper presents the geodatabase, which w...

The increasing availability of geospatial marine data provides an opportunity for hydrographic offices to contribute to the identification of “Potentially Polluting Marine Sites” (PPMS). These include shipwrecks, oil rigs, pipelines, and dumping areas. To adequately assess the environmental risk of these sites, relevant information must be collected and converted into a multi-scale geodatabase ...

The development of sustainable urban transport networks is a present priority for world leaders, national governors and local authorities. The challenge is to increase mobility reducing the adverse impacts of transport. The potential of Intelligent Transportation Systems (ITS) to provide solutions for the 21 century sustainable urban transport system has already been demonstrated in several pie...

Nowadays there is a lot of information about species composition, distribution and abundance terrestrial vertebrates in the Perm Territory different literature departmental papers. Consolidation data by creating theme geodatabase zoogeographical maps helps not only imagine structure on territory but also identify main patterns their habitat. There are some principles designing City which aim to...

Rapid urbanization and urban development must meet the requirements of smart green growth sustainable Vietnam. Hence, these are top challenges to be tackled by managers. Therefore, management databases accurate, relevant, transparent. At same time, simple access will enable users quickly find information they need. A combination attribute data spatial is a effective tool. Realistic data, integr...

Considering the huge amount of information, it becomes so difficult to deal with and understand only in condition they were organized, classified saved as data base that can be automatically make use without interfering its meaning significance. Here comes need invent new methods systems save such information with. An example is Management Information System Geographic System. The ability geogr...

The paper presents partial results of the expert cooperation between geologists and historians in Bohemian Switzerland (Elbe Sandstones) area focused on mapping documentation old quarries mining pits. More than three thousand abandoned for building stone were newly mapped registered within study area. Attention was given not only to preserved relics after their historical context: methods extra...
