A Mathematical Formulation of a Model for Landform Attributes Representation for Application in Distributed Systems
نویسندگان
چکیده
In this work we presented a methodology based on non linear regression for Landform Attributes representation. The equations to estimates the parameters of a two dimensional polynomial are shown and, for testing the methodology, it was used the data of Landform Attributes from the state of Minas Gerais (Brazil) obtained by the Digital Model of Elevation (DME) from GTOPO30 [5] project, in the form of a regular grid, with spacing of approximately 900m. The presented methodology can be used to minimize time in sending Landform Attributes information through network, to minimize space by storing the parameters of the estimated function and to make possible the distribution of the processing in different CPU, through internet network, for coefficients calculations.

In this paper, a state-of-the-art neuron mathematical model of neural tensor network (NTN) is proposed to RDF knowledge base completion problem. One of the difficulties with the parameter of the network is that representation of its neuron mathematical model is not possible. For this reason, a new representation of this network is suggested that solves this difficulty. In the representation, th...

Bike sharing systems (BSSs) offer a mobility service whereby public bikes, located at different stations across an urban area, are available for shared use. An important point is that the distribution of rides between stations is not uniformly distributed and certain stations fill up or empty over time. These empty and full stations lead to demand for bikes and return boxes that cannot be fulfi...

This paper presents LANDFORM, a customized GIS application for semi-automated landform classification based on the definitions of SPEIGHT (1990). A set of commands for GeoMedia was developed for an easy step-by-step generation of topographic attributes for the classification of landform elements. Using the new commands topographic attributes like curvature or elevation percentile were derived f...
