There are strong co-relations between material assignment, shape, and functionality of a part in overall product/assembly. However, these strong co-relations are rarely exploited for automated material assignment. We present a probabilistic graphical model-based approach to automatically assign materials to the parts (components) of a 3D object (assembly). The presented model performs material assignment by identifying the relations between shape, functionality, and materials of parts in the existing database objects. By learning the context dependent correlation without supervision from a set of objects and their segmented parts, the learned model can be used to assign proper real materials to the parts of a query object. Our primary contributions are: a) the real materials definition and assignment and b) assigning materials based on the functionality and form of the parts in the object. The performance of proposed computational approach is demonstrated by results of material assignment on various query objects without pre-specified material definitions.

And Function

One thing we can now surely say of the achievement of Wallace Stevens: He has written, over some thirty years, a whole and continuing poetry whose subject is the life, the form and function, of the imagination. In the recently published Transport to Summer that subject receives its broadest, most complex treatment, yet remains essentially as it was in his first volume, Harmonium: in his language, a problem in the relation of the imagined to the real; in more general language, of the world as known to the world as outside knowing. From beginning to end what has been basic is the predicament of the man who would know. If, read in and of themselves, the poems in Transport to Summer contrast vividly with those in Harmonium, the contrast is as much an aspect of continuity as of difference and opposition. It is a continuity that represents the growth and achievement which, for good and for bad, make the total of Stevens' work greater than the sum of its parts. Viewed thus, the poems in Transport to Summer are inevitable precisely as they show Stevens trying to finish what he began in Harmonium.

Abstract This study aims to interpret the visual qualities of the Assumption Chapel, located in the Cistercian monastery of Santa Maria La Real de Las Huelgas, Burgos. Rejecting the “mudejar” paradigm often used to explain the chapel’s connections to Andalusi architecture, the article instead considers its relationships to a group of twelfth- and thirteenth-century domed churches in Iberia and the French Pyrenees, as well as to Las Huelgas’s adjacent, late-Romanesque cloister. In so doing, it situates the Assumption Chapel in a broader context of monuments related to penitence and crusade in the Holy Land and Iberia. It also considers the chapel’s form and function in the light of Las Huelgas’s ritual topography. Most broadly, this study shows how seemingly incongruent visual languages—in this case Romanesque and Andalusi—can comprise a coherent program of imagery.

The Relationship

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).
