  2. Disruptive selection - Wikipedia

    en.wikipedia.org/wiki/Disruptive_selection

    These charts depict the different types of genetic selection. On each graph, the x-axis variable is the type of phenotypic trait and the y-axis variable is the amount of organisms. Group A is the original population and Group B is the population after selection. Graph 1 shows directional selection, in which a single extreme phenotype is favored.

  3. Differential structure - Wikipedia

    en.wikipedia.org/wiki/Differential_structure

    For a natural number n and some k which may be a non-negative integer or infinity, an n-dimensional C k differential structure [1] is defined using a C k-atlas, which is a set of bijections called charts between subsets of M (whose union is the whole of M) and open subsets of :

  4. Differentiable manifold - Wikipedia

    en.wikipedia.org/wiki/Differentiable_manifold

    In mathematics, a differentiable manifold (also differential manifold) is a type of manifold that is locally similar enough to a vector space to allow one to apply calculus. Any manifold can be described by a collection of charts . One may then apply ideas from calculus while working within the individual charts, since each chart lies within a ...

  5. Atlas (topology) - Wikipedia

    en.wikipedia.org/wiki/Atlas_(topology)

    A transition map provides a way of comparing two charts of an atlas. To make this comparison, we consider the composition of one chart with the inverse of the other. This composition is not well-defined unless we restrict both charts to the intersection of their domains of definition. (For example, if we have a chart of Europe and a chart of ...

    en.wikipedia.org/wiki/Five-point_stencil

    An illustration of the five-point stencil in one and two dimensions (top, and bottom, respectively). In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is a stencil made up of the point itself together with its four "neighbors".

    The Dana/Spicer Model 70 is an automotive axle manufactured by Dana Holding Corporation and has been used in OEM heavy duty applications by Chevrolet, Dodge, and Ford.It can be identified by its straight axle tubes, 10 bolt asymmetrical cover, and a "70" cast in to the housing, which is visually similar to the Dana 60.

  8. Chart pattern - Wikipedia

    en.wikipedia.org/wiki/Chart_pattern

    A chart pattern or price pattern is a pattern within a chart when prices are graphed. In stock and commodity markets trading, chart pattern studies play a large role during technical analysis. When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or ...
