Shading models that wrap around the hemisphere have been used to approximate subsurface scattering, area light sources, and softer reflectance profiles. We generalize a specific technique that has been used in games by parameterizing the amount of wraping while retaining important mathematical properties. We include details on how to incorporate theses models with spherical harmonic lighting. 1...

Background: Aortomyoplasty is a treatment for heart failure in which the latissimus dorsi muscle is wrapped around the aorta and stimulated to contract during diastole to provide chronic diastolic counterpulsation. We hypothesized that the manner in which the latissimus dorsi muscle is wrapped around the aorta determines the effectiveness of counterpulsation. Methods: Nine mongrel dogs were stu...

In this paper we present embeddings of complete binary trees into butterfly networks with or without wrap-around connections. Let m be an even integer and q = m+ LlogmJ-l. We show how to embed a 2+I -I-node complete binary tree T(q) into a (m + 1)2111+1_ node wrap-around butterfly B1l1(m +1) with a dilation of 4, and how to embed T(q) into a (m + 2)2+_node wrap-around butterfly B 1l1 (m +2) wit...

In this paper we present embeddings of complete binary trees into butter y networks with or without wrap-around connections. Let m be an even integer and q = m+ blogmc 1. We show how to embed a 2q+1 1-node complete binary tree T (q) into a (m + 1)2m+1node wrap-around butter y Bw(m+1) with a dilation of 4; and how to embed T (q) into a (m+2)2m+2-node wrap-around butter y Bw(m+2) with an optimal ...
