Dynamic Point Cloud Compression Based on Projections, Surface Reconstruction and Video Compression

open access: yesSensors, 2021
In this paper we will present a new dynamic point cloud compression based on different projection types and bit depth, combined with the surface reconstruction algorithm and video compression for obtained geometry and texture maps. Texture maps have been

Non-perturbative Gauge Groups and Local Mirror Symmetry [PDF]

open access: yes, 2001
We analyze D-brane states and their central charges on the resolution of C^2/Z_n by using local mirror symmetry. There is a point in the moduli space where all n(n-1)/2 branches of the principal component of the discriminant locus coincide. We argue that

Matrix geometries emergent from a point [PDF]

open access: yesReviews in Mathematical Physics, 2014
We describe a categorical approach to finite noncommutative geometries. Objects in the category are spectral triples, rather than unitary equivalence classes as in other approaches. This enables us to treat fluctuations of the metric and unitary equivalences on the same footing, as representatives of particular morphisms in this category. We then show

The influence of drill point geometry on tool life

open access: yesTehnički Glasnik, 2018
Drilling is a cutting process that uses a rotary cutting tool to cut a cylindrical hole in a solid material. During machining, drill bits are exposed to rapid wear at high temperature.

Assigning Quantum-Mechanical Initial Conditions to Cosmological Perturbations [PDF]

open access: yes, 2003
Quantum-mechanical initial conditions for the fluctuations of the geometry can be assigned in excess of a given physical wavelength. The two-point functions of the scalar and tensor modes of the geometry will then inherit corrections depending on which ...

Geometry of Quantum Projective Spaces [PDF]

open access: yes, 2012
In recent years, several quantizations of real manifolds have been studied, in particular from the point of view of Connes' noncommutative geometry. Less is known for complex noncommutative spaces.

Emergent unitarity, all-loop cuts and integrations from the ABJM amplituhedron

open access: yesJournal of High Energy Physics, 2023
We elaborate on aspects of a new positive geometry proposed recently, which was conjectured to be the four-point amplituhedron for ABJM theory. We study generalized unitarity cuts from the geometry, and in particular we prove that (1) the four-point ...

Statistical Properties of Strain and Rotation Tensors in Geodetic Network [PDF]

open access: yes, 2010
This article deals with the characteristics of deformation of a body or a figure represented by discrete points of geodetic network. In each point of geodetic network kinematic quantities are considered normal strain, shear strain, and rotation. They are

A point's point of view of stringy geometry [PDF]

open access: yesJournal of High Energy Physics, 2003
The notion of a "point" is essential to describe the topology of spacetime. Despite this, a point probably does not play a particularly distinguished role in any intrinsic formulation of string theory. We discuss one way to try to determine the notion of a point from a worldsheet point of view.
