Grid Method Classification of Islamic Geometric Patterns [chapter]

Ahmad M. Aljamali, Ebad Banissi
2004 Geometric Modeling: Techniques, Applications, Systems and Tools  
This paper proposes a rational classification of Islamic Geometric Patterns (IGP) based on the Minimum Number of Grids (MNG) and Lowest Geometric Shape (LGS) used in the construction of the symmetric elements  ...  The paper considers the current symmetric group theories only as arrangement patterns and not as classifications of IGP since they have a "global approach" and have failed to explore the possibilities  ...  Figure 3 . 3 Hexagonal and octagonal patterns by Issam El-Said in "Islamic Art and Architecture, The System of Geometric Design" [Sai93].  ...

Quantitative Analysis of Cell Nucleus Organisation

Carol Shiels, Niall M. Adams, Suhail A. Islam, David A. Stephens, Paul S. Freemont
2007 PLoS Computational Biology  
In this review we describe recent advances in the use of quantitative methods to understand nuclear spatial organisation and discuss some of the practical applications resulting from this work.  ...  The proteins' subcellular distribution patterns within interphase nuclei can be complex, ranging from diffuse to punctate or microspeckled, yet they all work together in a coordinated and controlled manner  ...  The positioning of nuclear compartments relative to the geometric centre is then calculated and usually expressed as a normalised distance because of variation in nuclear size and shape within cell populations  ...
