Scale invariant measures of pattern intensity and grain: A simulation experiment
MetadataShow full item record
We propose new dimensionless and scale-invariant measures for detection of pattern intensity, deined as the level of aggregation of individuals regardless their kind, and pattern grain, the level of segregation among individuals of at least two different kinds in point-pattern spatial data using tessellation methodology. Both real and simulated data on spatial distribution of plants in ecological communities show that the proposed parameters can be considered fingerprints of particular point patterns. This approach allows definition of both pattern intensity and grain for any kind of tessellated plane in an operational way, rendering these available for quantification and testing.

An examination of selected upper extremity functional activity from the perspective of the dynamic pattern theory of motor control.Ratanapinunchai, Jonjin (1996)An examination of throwing was performed in a controlled environment with the aim of identifying the control and order parameters of throwing as proposed by dynamic pattern theory. A pilot study was conducted to test the ...
Motor control during an active straight leg raise in pain free and chronic pelvic girdle pain subjectsBeales, Darren (2009)Aberrant motor control strategies have been identified in chronic pelvic girdle pain (PGP) subjects. It has been proposed that aberrant motor control strategies could provide a mechanism for ongoing pain and disability ...
Investigation of a management process: An exploratory study to identify underlying patterns in planningDickie, Carolyn (2007)This study linked the management activity of planning with Alexander et al.’s (1977) concept of pattern languages developed within architecture. Since the 1990s the concept has been expanded in the information systems ...
