Representing Robot Geometry as Distance Fields: Applications to Whole-body Manipulation
IEEE International Conference on Robotics and Automation, 2023In this work, we propose a novel approach to represent robot geometry as distance fields (RDF) that extends the principle of signed distance fields (SDFs) to articulated kinematic chains.

Geometry-Based Multi-Link Channel Modeling for High-Speed Train Communication Networks
IEEE transactions on intelligent transportation systems (Print), 2020The performance of distributed communication systems is commonly subject to the cross-correlation characteristics of multi-link channels. In this paper, we concentrate on the modeling of multi-link small-scale fading (SSF) channels in high-speed train ...

GEOMETRY OF QUANTUM VORTICES AND LINK INVARIANTS
International Journal of Modern Physics B, 1992We report on recent and ongoing research in the context of the geometric approach to quantum vortices and link invariants (via the Marsden-Weinstein theory and Chen’s iterated path integrals).

Development of multi-link geometry-based stochastic channel models
Loughborough Antennas and Propagation Conference, 2011A general aim of geometry-based stochastic channel models (GSCMs) is provision of imaginary, but realistic propagation channel responses that can be used as a reference channel in evaluating performance of mobile communication systems.

Solvation of Proteins: Linking Thermodynamics to Geometry
Physical Review Letters, 2007We calculate the solvation free energy of proteins in the tube model of Banavar and Maritan [Rev. Mod. Phys. 75, 23 (2003)10.1103/RevModPhys.75.23] using morphological thermodynamics which is based on Hadwiger's theorem of integral geometry. Thereby we extend recent results by Snir and Kamien [Science 307, 1067 (2005)10.1126/science.1106243] to hard ...

Geometry Links the Two Spheres
The Arithmetic Teacher, 1986When the educators of today were growing up, little information was available about the brain and its relationship to the acquisition of knowledge. Recent research has hown that the brain functions a two hemispheres, a right side and a left side. Each side influence our learning and emotions and provides the foundation for complementary but different ...

Some links between turtle geometry and analytic geometry
International Journal of Mathematical Education in Science and Technology, 1985The computer language LOGO facilitates the teaching of analytic geometry and calculus from the notion of curvature, through its ‘turtle geometry’ facility [2]. We provide some theoretical basis for finding turtle geometry equivalents of familiar curves in analytic geometry, and vice versa, by some simple methods which apparently have not been noticed ...

Multiple Coordination Geometries Supported by Methylene-Linked Guanidines
Inorganic Chemistry, 2004The methylene-linked bicyclic guanidine based on the 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine (hppH) framework provides a versatile platform able to support trigonal-planar, tetrahedral, and square-planar metal centers.

Link maps and the geometry of their invariants
Manuscripta Mathematica, 1988 This paper investigates several invariants of link homotopy. A link map consists of two maps \(f_ 1: S^ p\to S^ m\), \(f_ 2: S^ q\to S^ m\) whose images are disjoint; a link homotopy is a one-parameter continuous family of such maps. \(LM^ m_{p,q}\) denotes the set of link homotopy classes.
