BEYOND MAXIMUM INDEPENDENT SET: AN EXTENDED MODEL FOR POINT-FEATURE LABEL PLACEMENT
Map labeling point-feature label placement NP-hard
2016/7/8
Map labeling is a classical problem of cartography that has frequently been approached by combinatorial optimization. Given a set of features in the map and for each feature a set of label candidates,...
We propose a model of natural language inference which identifies valid inferences by their lexical and syntactic features, without full semantic interpretation. We extend past work in natural logic, ...
Analytical Solution of Two Extended Model Equations for Shallow Water Waves by He’s Variational Iteration Method
He’s Variational Iteration Method Shallow Water Wave Equation
2013/1/30
In this paper, we consider two extended model equations for shallow water waves. We use He’s variational iteration method (VIM) to solve them. It is proved that this method is a very good tool for sha...
Wave Speed in the Macroscopic Extended Model for Ultrarelativistic Gases
Wave Speed Macroscopic Extended Model Ultrarelativistic Gases
2011/1/19
An exact macroscopic extended model for ultrarelativistic gases,with an arbitrary number of moments, is present in the literature.Here we exploit equations determining wave speeds for that model.We fi...
Metadata Extended Model Based On Geological Domain Ontology

The current metadata modeling techniques can not meet the needs of knowledge conception expression, knowledge organization, and metadata semantic consistency in geological domain. This paper introduce...
Buoyancy- and Wind-Driven Circulation in an Extended Model of Potential Vorticity Homogenization
Buoyancy- and Wind-Driven Circulation Extended Model Potential Vorticity Homogenization
2008/7/3
An analytical model is proposed on the middepth water circulation between the surface wind-driven circulation and the deep buoyancy-driven circulation. The model consists of three and a half layers, w...
