Assigning semantic roles to the constituents of a natural language sentence is an important first step in translating natural language into a logical form for further processing. I present a statistical classifier which can perform this task using minimal syntactic cues. I use the syntactic and the semantic head of each constituent as the only features and present simple rules for extracting th...

In this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric discrete data structure that stores the different materials and an implicit representation for sculpting and reconstructing the surface of the terrain. Complex scenes can be edit...

This paper presents analytical estimates of the behavior exhibited by curved, archlike structures under radially directed and gravitational line loads. The behavior is shown to range from elementary beam bending at one end to a state of pure compression at the other, and its behavior can be tracked by an arch rise parameter that is a function of the arch’s semivertex angle, radius and thickness...

Marco Polo describes a bridge, stone by stone. “But which is the stone that supports the bridge?” Kublai Khan asks. “The bridge is not supported by one stone or another,” Marco answers, “but by the line of the arch that they form.” Kublai Khan remains silent, reflecting. Then he adds: “Why do you speak to me of the stones? It is only the arch that matters to me.” Polo answers: “Without stones, ...

xpansion of the jaws has been increasingly performed in orthodontics to achieve better occlusal and maxillary relationship, and so, to improve oral functions. Maxillary and mandibular expansion has been E Maxillary and mandibular expansion has been proposed to increase the arch perimeter and to avoid extractions during orthodontic treatment. This paper describes a novel method to produce expans...

Arches are an important part of the masonry architectural heritage and also serve as infrastructure for bridges culverts. The behavior testing structural health monitoring arches require effective measurement methods. There have been a lot methods applied regarding this subject, among which vision-based non-destructive very appealing. However, demands measuring accuracy range increase, labor ec...

Background: Panoramic radiography creates distortion in teeth position and inclination especially lateral areas of the arches due to acquisition curved shape dental arch. The aim this study was evaluate panoramic compared cone-beam computed tomography. Methods: Mesiodistal angulations were measured on radiography. buccolingual inclinations determined tomography scans. previous measurements then...
