Sierpinski triangle

The pattern is a set of Sierpinski triangles these are triangles in which an inner triangle, formed by connecting the midpoints of each side, has been removed.

Sierpinski triangle At each step an equilateral triangle with area equal to one-quarter of the remaining triangle is removed. 

Figure 2. The Sierpinski triangle is an example of a fractal object. It is self-similar, that is, small pieces are similar to the whole object (Reproduced with permission from reference 38. Copyright 1990 New York Academy of...

This kind of fractals sometimes is identified with deterministic constructions like Cantor set (in P), Sierpinski triangle or Sierpinski square (in P ), with Sierpinski pyramid or Menger sponge (in P ), and so on. In our case of electric impedance property. 

In addition to the DNA required to construct the input, only four DNA tiles are required (in principle) to grow arbitrarily large Sierpinski triangles. Experimentally, error-free Sierpinski triangles as large as 8 x 16 have been observed by atomic force microscopy. However, error rates (the frequency with which the... 

Figure 4. Constructing a Sierpinski carpet (a) quadrangle (b) triangle.

For fractal systems, the Hausdorff-Besicovitch dimension is equal to the similarity dimension, that is, df - d . We consider the triangular Sierpinski carpet as an example (Fig. 4). The iteration process means that the triangle is replaced by N = 3 triangles diminished with similarity coefficient K = 1 /2. Thus, the fractal dimension and the triangular Sierpinski carpet similarity dimension are given by... 

Another example of a regular fractal is a Sierpinski gasket shown in Fig. 1.13. Start with a filled equilateral triangle [Fig. 1.13(a)], draw the... 

Let us study the Sierpinski gasket array of Figure 8.17(a). A subarray employing three dipoles on the corners of an equilateral triangle h = 0.5X spacing on each side) and an expansion factor of 2 is utilized. Resolution is set to only 8 points/wavelength and three snapshots of the antennas electric near field are depicted in Figure 8.17(b). The simulations are conducted via the optimized operators of Section 5.4. 

Figure 16. Diagrams representing the six restricted generating functions for branched polymers on the two dimensional Sierpinski gasket. corresponds, for instance, to configurations where a part of the polymer joins two vertices of an r order triangle while one of its ends penetrates through the third vertex. The diagram on the right shows a term contributes to...
