  2. Botts' dots - Wikipedia

    en.wikipedia.org/wiki/Botts'_dots

    A round, white Botts' dot, surrounded by excess adhesive Botts' dots on Interstate 280, near the Sand Hill Road exit, Menlo Park, California. Botts' dots (turtles in Washington and Oregon or buttons in Texas and other southern states) are round non-reflective ceramic [1] raised pavement markers.

  3. Raised pavement marker - Wikipedia

    en.wikipedia.org/wiki/Raised_pavement_marker

    The surface of this type of vibrating coating line is distributed and scattered with raised bumps. Some bumps are coated with high-refractive-index glass beads.When a speeding vehicle runs over the raised road lines, it produces a strong warning vibration to remind the car driver of deviation from the lane.

  4. Plotting algorithms for the Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Plotting_algorithms_for...

    The top row is a series of plots using the escape time algorithm for 10000, 1000 and 100 maximum iterations per pixel respectively. The bottom row uses the same maximum iteration values but utilizes the histogram coloring method. Notice how little the coloring changes per different maximum iteration counts for the histogram coloring method plots.

  5. Road surface marking - Wikipedia

    en.wikipedia.org/wiki/Road_surface_marking

    Road markings in Indonesia are almost similar to markings in Europe and especially in the Netherlands. Markings are divided into four types, they are: Line marking, marks that are parallel to the axis of the road. Cross marking, mark that is crosswise to the axis of the road, such as at a stop line at a Zebra cross or at an intersection

  6. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    Graphs of maps, especially those of one variable such as the logistic map, are key to understanding the behavior of the map. One of the uses of graphs is to illustrate fixed points, called points. Draw a line y = x (a 45° line) on the graph of the map. If there is a point where this 45° line intersects with the graph, that point is a fixed point.

  7. Bump function - Wikipedia

    en.wikipedia.org/wiki/Bump_function

    An illustration of the sets in the construction. It is possible to construct bump functions "to specifications". Stated formally, if is an arbitrary compact set in dimensions and is an open set containing , there exists a bump function which is on and outside of .

  8. Distance from a point to a line - Wikipedia

    en.wikipedia.org/.../Distance_from_a_point_to_a_line

    The line with equation ax + by + c = 0 has slope -a/b, so any line perpendicular to it will have slope b/a (the negative reciprocal). Let (m, n) be the point of intersection of the line ax + by + c = 0 and the line perpendicular to it which passes through the point (x 0, y 0). The line through these two points is perpendicular to the original ...

  9. Straight-line diagram - Wikipedia

    en.wikipedia.org/wiki/Straight-line_diagram

    It illustrates why straight-line maps are more useful when only the sequence of stops is relevant. A straight-line diagram (abbreviated SLD) is a diagram of a road where the road is shown as a straight line. Such diagrams are usually produced by a highway department, and display features along the road, including bridges and intersecting roads.
