Surprisingly, an utterly imaginative "portrait" has become synonymous with Maimonides forever. How and when did this particular portrait become associated with Maimonides? This and many other intriguing questions regarding this portrait are systematically addressed, and its origins, possible inspiration, and hidden objectives are revealed.

Traditional portrait artists use a specific but open human vision methodology to create a painterly portrait of a live or photographed sitter. Portrait artists attempt to simplify, compose and leave out what’s irrelevant, emphasizing what’s important. While seemingly a qualitative pursuit, artists use known but open techniques such as relying on source tone over colour to indirect into a colour...

A method to recognize polarization constellations is proposed. Described method is based on analysis of torsion and curvature of three-dimensional curve. The three-dimensional curve is defined by states of polarization on the Poincare sphere. Key-Words: Fiber optics; Polarization light; Birefringence; Poincare sphere; Space curve; Frenet frame

Britain's National Portrait Gallery, which has recently acquired a striking new wing, has this autumn also obtained a very new kind of portrait. Artist Marc Quinn has created a 'genomic portrait' of Sir John Sulston, former director of the Wellcome Trust's Sanger Centre near Cambridge, who led the UK arm of the human genome project which announced completion of the first draft last year. As the...

Relighting a portrait in a single image is still a challenging problem, particularly when only a single artistic reference photograph or painting is provided. In this paper, we propose an artistic illumination transfer system for portraits based on a database of portrait images (photographs and paintings) associated with hand-drawn illumination templates (276) by artists. Users can select a ref...

This paper examines the recurrent behaviour of a class of hybrid systems which periodically switch between diierent rst order integrators. The analysis is based on studying the Poincare map of the hybrid system. For switched integrator systems, the Poincare maps are linear mappings thereby allowing easy characterization of the system's stability. Extending these results to more general classes ...

We present Poincare invariant domain wall (“3-brane”) solutions to some 5-dimensional effective theories which can arise naturally in string theory. In particular, we find theories where Poincare invariant solutions exist for arbitrary values of the brane tension, for certain restricted forms of the bulk interactions. We describe examples in string theory where it would be natural for the quant...
