DGD Gallery: Storage, sharing, and publication of digital research data [PDF]

open access: yes, 2015
We describe a project, called the "Discretization in Geometry and Dynamics Gallery", or DGD Gallery for short, whose goal is to store geometric data and to make it publicly available. The DGD Gallery offers an online web service for the storage, sharing,

Scalable quantum computation with fast gates in two-dimensional microtrap arrays of trapped ions [PDF]

open access: yes, 2020
We theoretically investigate the use of fast pulsed two-qubit gates for trapped ion quantum computing in a two-dimensional microtrap architecture. In one dimension, such fast gates are optimal when employed between nearest neighbours, and we examine the ...

A Comparative Study of Several Classical, Discrete Differential and Isogeometric Methods for Solving Poisson’s Equation on the Disk

open access: yesAxioms, 2014
This paper outlines and qualitatively compares the implementations of seven different methods for solving Poisson’s equation on the disk. The methods include two classical finite elements, a cotan formula-based discrete differential geometry approach and

Influence of camera distortions on satellite image registration and change detection applications [PDF]

open access: yes, 2008
Applications such as change detection and digital elevation model extraction from optical images require a rigorous modeling of the acquisition geometry.

Automatic simplification of the geometry of a cartographic line using contractive self-mapping – illustrated with an example of a polyline band

open access: yesPolish Cartographical Review, 2023
The present article is another attempt to adapt map geometry to automatic digital cartography. The paper presents a method of digital polyline generalisation that uses contractive self-mapping.

Methods of Parallel Voxel Manipulation for 3D Digital Printing [PDF]

open access: yes, 2007
A novel digital printing concept is explored for desktop fabrication of multimaterial objects with arbitrary 3D geometry. Digital objects are composed of many discrete, self-aligning voxels instead of continuous (analog) deposition techniques.

Bijective, Non-Bijective and Semi-Bijective Translations on the Triangular Plane

open access: yesMathematics, 2019
The triangular plane is the plane which is tiled by the regular triangular tessellation. The underlying discrete structure, the triangular grid, is not a point lattice. There are two types of triangle pixels. Their midpoints are assigned to them.

Tunable Digital Material Properties of 3D Voxel Printers [PDF]

open access: yes, 2008
Digital materials are composed of many discrete voxels placed in a massively parallel layer deposition process, as opposed to continuous (analog) deposition techniques.

A digital signature system based on hand geometry - Survey

open access: yesWasit Journal of Computer and Mathematics Science, 2022
 In recent years large number of emerging automated applications faces the need to have recognition abilities of persons using their own self biometrics, before they can access the applications services.
