Multi-scale hash encoding based neural geometry representation

open access: yesComputational Visual Media
Recently, neural implicit function-based representation has attracted more and more attention, and has been widely used to represent surfaces using differentiable neural networks.

No dimension independent Core-Sets for Containment under Homothetics

open access: yes, 2012
This paper deals with the containment problem under homothetics which has the minimal enclosing ball (MEB) problem as a prominent representative. We connect the problem to results in classic convex geometry and introduce a new series of radii, which we ...

Megamaps: Construction and Examples [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
We consider the usual model of hypermaps or, equivalently, bipartite maps, represented by pairs of permutations that act transitively on a set of edges E.

q-gram analysis and urn models [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Words of fixed size q are commonly referred to as $q$-grams. We consider the problem of $q$-gram filtration, a method commonly used to speed upsequence comparison. We are interested in the statistics of the number of $q$-grams common to two random texts (

A computational algebraic geometry approach to analyze pseudo-random sequences based on Latin squares

open access: yesAdvances in Computational Mathematics, 2018
Latin squares are used as scramblers on symmetric-key algorithms that generate pseudo-random sequences of the same length. The robustness and effectiveness of these algorithms are respectively based on the extremely large key space and the appropriate ...

Configuration Spaces Of Convex And Embedded Polygons In The Plane [PDF]

open access: yes, 2014
This paper concerns the topology of configuration spaces of linkages whose underlying graph is a single cycle. Assume that the edge lengths are such that there are no configurations in which all the edges lie along a line.

Rooted trees and moments of large sparse random matrices [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
In these expository paper we describe the role of the rooted trees as a base for convenient tools in studies ofrandom matrices. Regarding the Wigner ensemble of random matrices, we represent main ingredients ofthis approach.
