Cold Compaction and Macro‐Porosity Removal in Rubble‐Pile Asteroids: 1. Theory
Journal of Geophysical Research: Planets, Volume 127, Issue 10, October 2022., 2022 Abstract Many asteroids are likely to be have been shattered by collisions into fragments and reaccumulated as gravitationally‐bound rubble piles. These bodies may contain large porosities, although this picture may be complicated by compaction inside the asteroid body. Estimates of asteroid mass and volume imply a negative correlation between size and

Three‐Dimensional Discrete Element Analysis of Crushing Characteristics of Calcareous Sand Particles
Geofluids, Volume 2022, Issue 1, 2022., 2022 Particle crushing is an important factor affecting the mechanical characteristics of calcareous sand, but at present, most of relative studying methods rely on physical experiments. In order to study the influence of particle crushing characteristics on the micromechanics of calcareous sand, the 14‐fragment replacement method satisfying the Apollonian ...

In die gees van die Dionisiese: Marlene van Niekerk se aanhangersbrief aan Freddy Mercury
Tydskrif vir Letterkunde, 2022 Drawing on Nietzsche’s dichotomy between the Apollonian and Dionysian principles pertaining to classic tragedy, in this article, I consider the poem “Fan mail Freddy Mercury” by Marlene van Niekerk, from Kaar (2013) from that perspective.

Reach‐Avoid Games with a Time Limit and Detection Range: A Geometric Approach
Complexity, Volume 2022, Issue 1, 2022., 2022 The reach‐avoid game theory is an ideal tool to handle the conflicts among intelligent agents and has been previously studied assuming full state information and no time limits on the players in the past decades. In this article, we extend the problem by requiring the defender to detect the attacker and adding maximum operation time constraints to the ...

Quasicircles and width of Jordan curves in CP1
Bulletin of the London Mathematical Society, Volume 53, Issue 2, Page 507-523, April 2021., 2021 Abstract We study a notion of ‘width’ for Jordan curves in CP1, paying special attention to the class of quasicircles. The width of a Jordan curve is defined in terms of the geometry of its convex hull in hyperbolic three‐space. A similar invariant in the setting of anti‐de Sitter geometry was used by Bonsante–Schlenker to characterize quasicircles ...

Degree distribution of random Apollonian network structures and Boltzmann sampling [PDF]
Discrete Mathematics & Theoretical Computer Science, 2007 Random Apollonian networks have been recently introduced for representing real graphs. In this paper we study a modified version: random Apollonian network structures (RANS), which preserve the interesting properties of real graphs and can be handled ...

Complexity, Volume 2021, Issue 1, 2021., 2021 Societies have always used their heritage to remain resilient and to express their cultural identities. Today, all the still‐available experiences accrued by human societies over time and across space are, in principle, essential in coping with the twenty‐first century grand challenges of humanity (refer to the 17 UN Sustainable Development Goals ...

Polygon-Based Hierarchical Planar Networks Based on Generalized Apollonian Construction
Physics, 2021 Experimentally observed complex networks are often scale-free, small-world and have an unexpectedly large number of small cycles. An Apollonian network is one notable example of a model network simultaneously having all three of these properties.

Apollonian Circle Packings: Geometry and Group Theory III. Higher Dimensions [PDF]
, 2004 This paper gives $n$-dimensional analogues of the Apollonian circle packings in parts I and II. We work in the space $\sM_{\dd}^n$ of all $n$-dimensional oriented Descartes configurations parametrized in a coordinate system, ACC-coordinates, as those $(n+
