Random-Radius Ball Method for Estimating Closeness Centrality

Proceedings of the AAAI Conference on Artificial Intelligence, 2017
In the analysis of real-world complex networks, identifying important vertices is one of the most fundamental operations. A variety of centrality measures have been proposed and extensively studied in various research areas. Many of distance-based centrality measures embrace some issues in treating disconnected networks, which are ...

Mathematical modeling of closed cycles of ball grinding

Soviet Mining Science, 1986
Principles of the mathematical description of the grinding process have been developed which make use of linear models of population balance and substitute for the real distribution of the time of grain processing inside the mill a combination of ideal extrusion and ideal mixing.

Intersecting with a Closed Ball

1996
In order to examine the local geometry of a figure, we will need to focus attention on the collection of points that lie close to any given point. We will dissect the figure mentally, as it were. To be clear about what this means, it is best to employ some concepts from set theory.

A closed form solution to the one-ball geolocation problem

SPIE Proceedings, 2016
We address the problem of determining the source location of an electromagnetic signal from the signal received by one or more moving receivers. We base our process on cross-spectral methods that were developed in the early 1980’s for analysis and demodulation/despreading of communication and spread spectrum signals and were later applied to speech ...

Driving with your eyes closed: A reply to Ball

Journal of Housing and the Built Environment, 2000
This brief paper responds to Ball'scritique of my article, `Housing, Equality andNeutrality'. I suggest that Ball has bothmisunderstood and misrepresented my position, inparticular my three proposals for reform. Inresponse to Ball, I state that these proposalsmerely extend policy initiatives currently seen inthe UK, Europe, Australasia and the USA.

Inexpensive wooden-ball models for close-packed crystal structures

American Journal of Physics, 2000
The two common close-packed structures, face-centered cubic (fcc) and hexagonal close packed (hcp), play a leading role in discussions of crystal structure in solid-state physics courses. It is also common in crystal chemistry to describe many inorganic crystal structures based on either the fcc or the hcp structure, generally with one atom type ...

Validity of the union of uniform closed balls conjecture

2011
Summary: A proof is provided for the union of uniform closed balls conjecture introduced in a previous paper of the authors [''Proximal smoothness and the exterior sphere condition'', J. Convex Analysis 16 501--514 (2009; Zbl 1179.49019)]; see also \textit{C. Nour}, \textit{R. J. Stern}, and \textit{J.
