An Illusion of Spatial Hierarchy: Spatial Hierarchy in a Random Configuration
Environment and Planning A: Economy and Space, 1996In this paper we show the properties of a spatial hierarchy found in a random configuration in which points are randomly placed on a plane and ranks are randomly assigned to these points. First we show a method of detecting a spatial hierarchy in a configuration of ranked points on a plane (not necessarily the random configuration).

Effect of spatial configuration on motion aftereffects
Journal of the Optical Society of America A, 1993Sensitivity to motion was measured by the percentage of trials on which an observer reported seeing motion of briefly presented high-contrast sinusoidal gratings moving over a range of velocities. The psychometric curve was remeasured following adaptation to a grating moving in one direction for an extended period of time.

Spatial configuration of mRNA 5′-terminus
Nature, 1977Nuclear magnetic resonance investigation has revealed that the 5'-terminus m7G5'ppp5'Am of mRNA displays a spatial configuration in which the bases form stacked arrays. Details of the conformation as derived from coupling constants, shift trends and ring current considerations are discussed.

On the Generation of Linear Representations of Spatial Configuration
Environment and Planning B: Planning and Design, 1998It has been shown that, with space syntax, spatial configuration can be described as a set of lines covering all the areas of a layout and all the ways of moving around the one-dimensional and two-dimensional boundaries that it comprises. In this paper we propose alternative formal definitions of linear representations of spatial configuration and the ...

This second paper on constructions of spatial configurationsfollows the author’s paper of 1994 [2]. For the first timeagain new spatial configurations are constructed, in particular aconfiguration (338)2, the smallest known configuration (v 8)2, andseveral configurations (v 9)2, in particular forv = 40 and for v ≥ 43.

The Qualitative Spatial Reasoning to Mechanical Configuration
2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008A qualitative reasoning approach is used for the spatial configuration of mechanisms in conceptual design phase. The appropriate types of mechanisms are chosen firstly for a specific reasoning task. The qualitative vectors of the basic components are given to construct the complicated mechanism.

The prevailing paradigms treat space as a pre-existing stage. This paper strictly limits its inquiry to the nature of spatial configuration, proposing a complete inversion: space is not fundamental; it is the emergent topology of synchronous co-presence.

A FILTRATION OF THE CONFIGURATION SPACE OF SPATIAL POLYGONS
Advances and Applications in Discrete Mathematics, 2019Summary: Let \(\mathcal{P}_n\) be the configuration space of equilateral spatial \(n\)-gons. For \(\theta\in [0,\pi]\) and \(k\in \{0,1,\dots ,n\}\) let \(\mathcal{P}^k_n(\theta)\) be the subspace of \(\mathcal{P}_n\) consisting of elements whose first \(k\) bond angles are \(\theta \).

Virtual collaboration: effect of spatial configuration on spatial statements production
Cognitive Processing, 2015When guiding a remote collaborator in a virtual environment, people often take an addressee-perspective, which may have a high cognitive cost. In order to improve collaborative virtual environments, a better understanding of how operators share spatial information is needed.
