Insertion and deletion tolerance of point processes [PDF]
, 2013 We develop a theory of insertion and deletion tolerance for point processes. A process is insertion-tolerant if adding a suitably chosen random point results in a point process that is absolutely continuous in law with respect to the original process ...

On a class of point-reflection geometries
Discrete Mathematics, 1994 In [\textit{C. F. Manara} and the second author, Rend. Sci. Mat. Appl. A 125, No. 2, 203-217 (1991; Zbl 0798.51017)] an axiomatic approach to point-reflection geometries has been given (generalizing the case of Euclidean planes where each point is the centre of a unique reflection).

Linear-Size Universal Point Sets for One-Bend Drawings [PDF]
, 2015 For every integer $n ge 4$, we construct a planar point set $S_n$ of size $6n-10$ such that every $n$-vertex planar graph $G$ admits a plane embedding in which the vertices are mapped to points in $S_n$, and every edge is either a line segment or a ...

The influence of drill point geometry on tool life
Tehnički 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.

Simulation of cluster point processes without edge effects [PDF]
, 2002 The usual direct method of simulation for cluster processes requires the generation of the parent point process over a region larger than the actual observation window, since we have to allow for all possible parents giving rise to observed daughter ...

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

ASSESSING THE ALIGNMENT BETWEEN GEOMETRY AND COLORS IN TLS COLORED POINT CLOUDS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 The integration of the color information from RGB cameras with the point cloud geometry is used in numerous applications. However, little attention has been paid on errors that occur when aligning colors to points in terrestrial laser scanning (TLS ...

Geometry Students’ Arguments About a 1-Point Perspective Drawing
REDIMAT, 2017 The practice of formulating and justifying claims is a fundamental aspect of doing mathematics, and in geometry, students’ use of diagrams is integral to how they establish arguments. We applied Toulmin’s model to examine 23 geometry students’ arguments

Polylidar3D-Fast Polygon Extraction from 3D Data
Sensors, 2020 Flat surfaces captured by 3D point clouds are often used for localization, mapping, and modeling. Dense point cloud processing has high computation and memory costs making low-dimensional representations of flat surfaces such as polygons desirable.
