  2. Vitrified clay pipe - Wikipedia

    en.wikipedia.org/wiki/Vitrified_clay_pipe

    VCP products use clay as a major component in its production, making its raw materials environmentally friendly. The manufacturing process has been fine-tuned for centuries and was designed to be fiscally responsible which had the added benefit of being environmentally responsible.

  3. Hyperbolic geometry - Wikipedia

    en.wikipedia.org/wiki/Hyperbolic_geometry

    For example, two distinct lines can intersect in no more than one point, intersecting lines form equal opposite angles, and adjacent angles of intersecting lines are supplementary. When a third line is introduced, then there can be properties of intersecting lines that differ from intersecting lines in Euclidean geometry. For example, given two ...

  4. Hyperboloid - Wikipedia

    en.wikipedia.org/wiki/Hyperboloid

    One-sheeted hyperboloids are used in construction, with the structures called hyperboloid structures. A hyperboloid is a doubly ruled surface; thus, it can be built with straight steel beams, producing a strong structure at a lower cost than other methods. Examples include cooling towers, especially of power stations, and many other structures.

  5. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    The linkages between leads were once simple crossings of lines. With the arrival of computerized drafting, the connection of two intersecting wires was shown by a crossing of wires with a "dot" or "blob" to indicate a connection. At the same time, the crossover was simplified to be the same crossing, but without a "dot".

  7. Conic section - Wikipedia

    en.wikipedia.org/wiki/Conic_section

    In the real projective plane, since parallel lines meet at a point on the line at infinity, the parallel line case of the Euclidean plane can be viewed as intersecting lines. However, as the point of intersection is the apex of the cone, the cone itself degenerates to a cylinder, i.e. with the apex at infinity.

  8. Position resection and intersection - Wikipedia

    en.wikipedia.org/wiki/Position_resection_and...

    Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions.In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point.

  9. Line–plane intersection - Wikipedia

    en.wikipedia.org/wiki/Line–plane_intersection

    The intersection of a ray of light with each plane is used to produce an image of the surface. In vision-based 3D reconstruction , a subfield of computer vision, depth values are commonly measured by so-called triangulation method, which finds the intersection between light plane and ray reflected toward camera.
