Buffon’s needle, Varignon’s theorem, Jung’s theorem, Sylvester's problem, are all hints that random allocations of spatial objects often obey to geometric restrictions. Further, it can be speculated that, so long as population distributions on surfaces might be represented by strings of symbols, there is no apparent reason why the arcsine law and ...

Simplicity in Complex Spatial Systems
2009In the past decade, complexity has become an important and fascinating domain for advanced research on nonlinear dynamics, in which a multiplicity of scientific fields are involved (physics, life sciences, social sciences, economics, geography, and so forth).

Spatial Complexity, Visual Complexity and Aesthetics
2020The concept of “visual complexity” is related to spatial complexity. From landscapes to paintings and fractals, aesthetic appeal is directly related to spatial complexity (or, at least, to its determinants). In this chapter, it is examined how and why: (a) neither spatial complexity nor simplicity guarantee aesthetic appeal; (b) quite often, neither ...

IEEE/ACES International Conference on Wireless Communications and Applied Computational Electromagnetics, 2005., 2005
The conventional cell averaging constant false alarm rate (CFAR) criterion and its variations work well only in strictly spatially stationary environments. In non-homogeneous environments, clutter map (scan-by-scan) processing is deployed. The performance of this method degrades in the presence of slow targets.

Spatial Complexity, Psychology and Qualitative Complexity
2020How is spatial complexity perceived by humans? The study of spatial complexity is scale-dependent: a spatial entity that may look simple at some spatial level, may reveal many details if examined closer at finer spatial scales. To perceive complexity, we often resort to generalizations: thematic (grouping up similar themes, i.e.

Abstract : The work done with this grant was on the topic of complex spatial dynamics, and included progress in three areas: (1) analysis of the space of cellular automation rules, particularly with an eye toward the question of where complex cellular automata live in this space, and (2) analyzing data from complex spatial systems, and (3) nonlinear ...

Spatial filters for complex wavefront modulation
Applied Optics, 2013In this paper we propose a method to generate independent and simultaneous phase and amplitude modulation by a phase-only spatial light modulator and Fourier filtering. The incident light is modulated by a suitable phase pattern containing high spatial frequencies.
