In the early twentieth century, the Bauhaus revolutionized art and design by using simple colors and forms. Wassily Kandinsky was especially interested in the relationship of these two visual attributes and postulated a fundamental correspondence between color and form: yellow triangle, red square and blue circle. Subsequent empirical studies used preference judgments to test Kandinsky's origin...

louis hubert farabeuf was born in bannost (sein-et-marne) on may 6th 1841 and died in beton-bazoche (aisne) in august 1910. he was professor and director of the anatomical department of the faculty of medicine in paris until 1878. in 1879, he founded the school of practical studies in paris, which contributed to anatomical studies. farabeuf designed many surgical procedures. his manual of opera...

Species invasion is a complex, multifactor process. To encapsulate this complexity into an intuitively appealing, simple, and straightforward manner, we present an organizational framework in the form of an invasion triangle. The invasion triangle is an adaptation of the disease triangle used by plant pathologists to help envision and evaluate interactions among a host, a pathogen, and an envir...

In this paper, we introduce the notion of co-annihilator of a subsetin a triangle algebra. It is shown that the co-annihilator of asubset is an interval valued residuated lattice (IVRL)-filter. Also, aspecial set of a triangle algebra is defined and the relationshipbetween this set and co-annihilator of a subset in triangle algebrais considered. Finally, co-annihilators preserving congruencerel...

In buildings with triangular plan, the center of mass and rigidity cannot geometrically match all possible directions of the earthquake. This will result in torsional moments in the stories causing the building to rotate around the center of rigidity. In this paper, via response spectrum analysis (RSA) and nonlinear static analysis, the seismic behavior of 5-, 10- and 15-story steel structures ...

In this paper, we investigate subdivision tree representations of arbitrary triangle meshes. By subdivision, we mean the recursive topological partitioning of a triangle into subtriangles. Such a process can be represented by a subdivision tree. We identify the class of regular triangle meshes, those that can be losslessly represented by a nontrivial subdivision tree, i.e. by a subdivision tree...

To a simple graph $G=(V,E)$, we correspond a simple graph $G_{triangle,square}$ whose vertex set is ${{x,y}: x,yin V}$ and two vertices ${x,y},{z,w}in G_{triangle,square}$ are adjacent if and only if ${x,z},{x,w},{y,z},{y,w}in Vcup E$. The graph $G_{triangle,square}$ is called the $(triangle,square)$-edge graph of the graph $G$. In this paper, our ultimate goal is to provide a link between the ...

purpose: to compare the results of two different methods of frontalis suspension using fascia lata in congenital ptosis. methods: in a randomized clinical trial, double triangle sling was compared with single triangle sling using fascia lata. eight patients with unilateral and 11 patients with bilateral congenital ptosis were randomly assigned for each procedure. results: there was no statistic...

Triangle meshes are very important entities in computer graphics and form the building blocks for variety of entities like terrains & surfaces and solid objects as shown in the example below. Triangle meshes are very suitable simply because of the fact that triangles can approximate almost any surface and at the same time remain computationally cheap. It is essential to understand what triangle...
