A heuristic method to find asymptotic solutions a system of non-linear wave equations near null infinity is proposed. The non-linearities in this model, dubbed good-bad-ugly, are known mimic the ones present Einstein field (EFE) and we expect be able exploit derive an expansion for metric General Relativity (GR) close that goes beyond first order as performed by Lindblad Rodnianski leading asym...

Radial, space-filling (RSF) techniques for hierarchy visualization have several advantages over traditional node-link diagrams, including the ability to efficiently use the display space while effectively conveying the hierarchy structure. Several RSF systems and tools have been developed to date, each with varying degrees of support for interactive operations such as selection and navigation. ...

In this paper we describe the application of the Golden Ratio to three-dimensional facial scans. The Golden Ratio is believed to be a blueprint for facial features that conform to beauty. Faces are scanned using the Minolta VI-700 range data scanner. The acquired 3D meshes are viewed and manipulated using 3DS Max and MAXScript. A Golden Mask, constructed based on the Golden Ratio is used to ind...
