Remotely sensed images and the thematic maps derived from such images are invaluable sources of information for GIS databases, in terms of providing spatial and temporal information about the nature of Earth surface materials and objects. One of the techniques that has emerged recently, and which has made a great impact on scientific community, is that of artificial neural networks (ANNs). ANNs...

We introduce a Reactive Data Structure, that is a spatial data structure with detail levels. The two properties, spatial organization and detail levels, are the basis for a Geographic Information System with a multi-scale database. A reactive data structure is a novel type of data structure cartering to S It is presented here as a modification of the binary space partioning tree that includes d...

In this paper a new algorithm has been developed to enhance spatial structure by using texture feature extraction. Then, this algorithm has been programmed and an integrated program has been prepared by using Microsoft Visual C++ 6.0. In order to ascertain the usefulness of this algorithm, it has been applied in two groups of images, the first group consisted of three images of different featur...

Traditionally it has been thought that the overall organisation of categories in the brain is taxonomic. To examine this assumption, we had adults sort 140-150 diverse, familiar objects from different basic-level categories. Almost all the participants (80/81) sorted the objects more thematically than taxonomically. Sorting was only weakly modulated by taxonomic priming, and people still produc...

In this paper we discuss about the need of a new DEM representation for simulation in GIS. This leads us to analyse through quality criteria the current DEM structures. Then we propose a new DEM representation adapted for spatial and graph terrain analysis. An algorithm is presented and the qualities of this structure are analysed. Finally, this structure is used in a thematic application for a...

This study investigates the comprehension of three kinds of subject-extracted relative clauses (SRs) in Mandarin Chinese: standard SRs, relative clauses involving the disposal ba construction ("disposal SRs"), and relative clauses involving the long passive bei constructions ("passive SRs"). In a self-paced reading experiment, the regions before the relativizer (where the sentential fragments a...

Verbs are central to sentence processing, as they encode argument structure (AS) information, i.e., information about the syntax and interpretation of the phrases accompanying them. The behavioral and neural correlates of AS processing have primarily been investigated in sentence-level tasks, requiring both verb processing and verb-argument integration. In the current functional magnetic resona...

In this introductory text, we present some of the main lexical semantics paradigms frequently used in Computational Linguistics circles. Most of the elements presented here come from different linguistic traditions. To make the text homogeneous, we have somewhat reformulated or simplified some of them. We successively present the notions of argument structure and thematic roles, the notion of a...
