Nicomachean Ethics, Aristotle discusses "Distributive justice in accordance with geometrical proportion." (Book V, Ch.3). This suggests that Aristotle used a geometrical model in this context. But the original drawings did not survive and the exact nature of the corresponding model

Each individual tolerance requirement must be met. The general geometrical tolerances may thus also be applied even if the features are everywhere at their

techniques are categorized into two groups: Geometrical based methods [6] and appearance based methods [7]. A geometrical representation of the face is constructed by extracting the shape and the positions of facial components. A face image has been represented by 34 fiducial points in an early effort by [8].

Key words: Geometrical and dimensional accuracies, die shape modifications, cold forging. INTRODUCTION Cold forging has become one of the major manufacturing methods because of its high strength and good dimensional accuracy. Cold forging is governed by many factors that could affect the dimensional and geometrical

A limitation of these methods often lies in their execution time. We propose, in the spirit of [13], to integrate geometrical and color features along edges in the pose .

2) The use of geometrical techniques in complex analysis. This clari es the study of con-formal maps, extends the usual study to more general surfaces, and shows how geometrical concepts are ffe in classical problems, from the Riemann mapping theorem to Picard’s theorem. An appendix discusses applications of the Poincar e metric on the disk.

3. GEOMETRICAL INTERPRETATION It is convenient to use geometrical concepts to describe the minimiza tion procedure. We do so by considering the variables x to be the coordinates of a point in an N-dimensional linear space. As shown in Fig. la, the set of X for which f (x) is constant forms an N-1 dimensional surface in this space.

for the calculation of various geometrical features e.g area, length, width as shown in the Table-I. As accuracy is the major concern of every experiment, we take hare 20 random sample images for every variety of leaves. The geometrical and morphological features of the twenty sample leaf images for "Amrapali" leaves are

construe them as induced geometrical extents. Taken together with asserted geometrical extents (e.g., those of civil structures such as buildings and roads and bridges, or of geographical features, such as forests, rivers, lakes, mountains), physical phenomena can then be targetted by high-level, declarative spatial and spatio-temporal queries.

Figure 1.3 illustrates a schematic image of this process. The scanned data of produced parts will be utilized to generate a digital twin for each physical assembly. Since the objective is to maximize geometrical qual-ity, the digital twin should be capable of predicting the geometrical deviations of the physical assembly.

The geometrical thickness of the layers rarely exceeds 5 X 10-5 cm (500 ) and in most cases is about one fifth of this value. A more convenient parameter by which to specify layer thickness is the "optical thickness" defined as the product of the refractive index and the geometrical thickness.

Refraction Geometrical optics uses rays to represent light propaga-tion through an optical system. According to Fermat's principle, rays will choose a path that is stationary with
