Triangles perimeter

Unique is the number of unique 3-point pharmacophores displayed by the whole library, Conscore is a term that can force a design to fill specific 3-point pharmacophores and avoid others i.e. to complement an existing compound collection). Partscore is used to force a distribution of shape related descriptors heavy atoms (ha), largest triangle perimeter for a pharmacophore in the library (pp) and largest triangle are for a pharmacophore in the library (pa). S is the total number of molecules that pass certain filters, such as a limit of molecular flexibility. Totpharm is the total of pharmacophores displayed by the entire library and Flex is the normalised number of conformations accessed by the library of n molecules. The terms a, b, Y and Z are user defined weights. [Pg.382]

At each k point, H, S, C, and E in Eq. [25] are 2x2 matrices in the basis of and 4>b. Again, H and S must be computed to find the unknown matrices C and E. For symmetry reasons, only the asymmetric part of the Brillouin zone needs to be explored instead of the entire zone, and because the full representation of a 7i-type band structure for graphite would be three-dimensional, we can start by exploring a representative monodimensional path (as is usually done for three-dimensional structures). The most obvious choice is the triangle perimeter, and in particular, the special positions E, M, and K are expected to be topologically interesting for their symmetry properties. [Pg.25]

By following the lines connecting two sources of circled information, the boxed result in the perimeter of the triangle may be established. Thus kp is evaluated from r and n, . [Pg.373]

The 12 sets of basic geometry problems in this section involve lines, angles, triangles, rectangles, squares, and circles. For example, you may be asked to find the area or perimeter of a shape, the length of a line, or the circumference of a circle. In addition, the word problems will illustrate how closely geometry is related to the real world and to everyday life. [Pg.132]

Ifthe two triangles in the diagram are similar, with /.A equal to ZD, what is the perimeter of triangle DEF. [Pg.142]

Krishnamurthi, Kumar, and Datta (K7) employed a circular orifice of arbitrarily chosen dimensions as the standard, and constructed two sets of noncircular orifices having either the perimeter or the area equal to that of the standard orifice. The configurations chosen were an equilateral triangle, a square, and a rectangle. The system used by these authors was air-water, and their studies were confined to extremely small flow rates (<0.5 cm3/sec). Their results indicate that noncircular orifices do not utilize their entire perimeter for bubble formation, and, for equi-sided orifices at low frequencies of formation, the bubble is formed as if from a circle inscribed in the noncircular orifice. In this range, the perimeter and the area are important in determining the final bubble size. [Pg.321]

First, notice that the measures are all different units. Change all the measures to the same unit. The best choice is to change everything to yards, because inches will result in some really big numbers. Also, the sides all come out to being a whole number of yards. The second step is to find the perimeter of the triangle. P = a + b + c. The semi-perimeter, s, is half the perimeter. Then, finally, put all the values in their correct places in the formula and simplify. [Pg.131]

FIGURE 10 Example of chaos for AlAo 1.45, cu/stable fixed points have been found, (b) The time series for a chaotic trajectory after 150 periods of forced oscillations. The arrows indicate a near periodic solution with period 21. The periodicity eventually slips into short random behaviour followed by long near period behaviour. This near periodicity reflects the fact that the chaotic attractor forces the trajectory to eventually pass near the stable manifolds of the period 21 saddle located around the perimeter of the chaotic attractor. [Pg.330]

Thus, Fig. 8.66 pictures the triangular delta 6(71727) or 71727, which equals zero if the parameters 71, j2 and 7 cannot compose the triangle having an integer perimeter. If j2 = 0, then we have Fig. 8.6c, corresponding to the usual Kronecker delta condition, namely,... [Pg.67]

Figure 3. Triangular diagram to represent a triatomic potential-energy surface. For any point of the triangle KLM the molecular perimeter is constant, R, + R2 + R3 = constant = /i. The unshaded area of the K L M triangle corresponds to the space physically accessible to the nuclei for that perimeter. Inside the K L M triangle, one has R + R 2 + R = //2, where R (i = 1,2,3) are the Pekeris coordinates. Figure 3. Triangular diagram to represent a triatomic potential-energy surface.

Line tensions (r) are forces acting in the three-phase contact perimeter. Their SI-unit is N. When r > 0 the line tension tries to shorten the perimeter, for r < 0 the trend is the other way around. Line tensions are typiccdly excess qucuitities in that their action comes on top of that of the three interfacial tensions constituting the contact angle, and which are related through Young s law or Neumann s triangle. [Pg.627]
