Canonical tree representation of distance hereditary graphs and its applications
, 2006
"... The class of distance hereditary graphs consists of the isometric graphs. That is, for each pair of vertices, its distance is invariant for any induced path in a distance hereditary graph. In the paper, a canonical tree representation of a distance hereditary graph is proposed. A linear time algorit ..."

Galactic supernova remnants: an updated catalogue and some statistics
 Bulletin of the Astronomical Society of India
, 2004
"... Abstract. A catalogue of 231 Galactic supernova remnants (SNRs) is presented, and the selection effects applicable to the identification of remnants at radio wavelengths are discussed. In addition to missing low surface brightness remnants, small angular size – i.e. young but distant – remnants are ..."

The Canonical Metric for Vector Quantization
, 1995
"... The Problem 1 Abstract To measure the quality of a set of vector quantization points a means of measuring the distance between two points is required. Common metrics such as the Hamming and Euclidean metrics, while mathematically simple, are inappropriate for comparing speech signals or images. In t ..."

The Lipschitz continuity of the distance function to the cut locus
 Trans. Amer. Math. Soc
"... Abstract. Let N be a closed submanifold of a complete smooth Riemannian manifold M and Uν the total space of the unit normal bundle of N. Foreach v ∈ Uν,letρ(v) denote the distance from N to the cut point of N on the geodesic γv with the velocity vector ˙γv(0) = v. The continuity of the function ρ ..."

Recognition of Human Gaits
, 2001
"... We pose the problem of recognizing different types of human gait in the space of dynamical systems where each gait is represented. Established techniques are employed to track a kinematic model of a human body in motion, and the trajectories of the parameters are used to learn a representation of a ..."

Canonical elements for collision orbits
, 2000
"... I derive a set of canonical elements that are useful for collision orbits (perihelion distance approaching zero at fixed semimajor axis). The coordinates are the mean anomaly and the two spherical polar angles at aphelion. The purpose of this short note is to derive a set of canonical orbital elemen ..."

CANONICAL TRACE ANOMALIES*
, 1972
"... *Work supported by the U. S. Atomic Energy Commission. We discuss the anomalies present in broken scale invariance trace identities which result from assuming that products of hadronic currents have a canonical singularity structure at short distances. The analysis is performed qualitatively in conf ..."

Reshaping the Canonical Face
"... o meet this requirement. In our application, the ears, eyes, and lips are handled separately. First, we translate all vertices so that the center point of the model (determined by the vertex visibility test mentioned above) coincides with the coordinate system origin. We then move the vertices so th ..."

that they are at a unit distance from the origin. At this point, all the vertices of all triangles making up the model are on the surface of the unit sphere. The weighted influence of each landmark is then calculated into each source vertex's new position. Then, for each of these source vertices we determine
Stellar masers, circumstellar envelopes, and supernova remnants
