  2. Standard rate turn - Wikipedia

    en.wikipedia.org/wiki/Standard_rate_turn

    A standard rate turn is defined as a 3° per second turn, which completes a 360° turn in 2 minutes. This is known as a 2-minute turn, or rate one (180°/min). Fast airplanes, or aircraft on certain precision approaches, use a half standard rate ('rate half' in some countries), but the definition of standard rate does not change.

  3. Finite element method - Wikipedia

    en.wikipedia.org/wiki/Finite_element_method

    The second step is discretization, where the weak form is discretized in a finite-dimensional space. After this second step, we have concrete formulae for a large but finite-dimensional linear problem whose solution will approximately solve the original BVP. This finite-dimensional problem is then implemented on a computer.

  4. Scale height - Wikipedia

    en.wikipedia.org/wiki/Scale_height

    A schematic depiction of the force balance in a gas disk around a central object, e.g., a star. For a disk of gas around a condensed central object, such as, for example, a protostar, one can derive a disk scale height which is somewhat analogous to the planetary scale height.

  5. Gaussian quadrature - Wikipedia

    en.wikipedia.org/wiki/Gaussian_quadrature

    The Gaussian quadrature chooses more suitable points instead, so even a linear function approximates the function better (the black dashed line). As the integrand is the third-degree polynomial y(x) = 7x 3 – 8x 2 – 3x + 3, the 2-point Gaussian quadrature rule even returns an exact result.

  6. List of virtual reality headsets - Wikipedia

    en.wikipedia.org/wiki/List_of_virtual_reality...

    Comparison chart of per-eye headset resolutions. There are two primary categories of virtual reality (VR) headsets: Standalone – devices that have all necessary components to provide virtual reality experiences integrated into the headset. Mainstream standalone VR platforms include:

  7. ZF 9HP transmission - Wikipedia

    en.wikipedia.org/wiki/ZF_9HP_transmission

    The 9HP is only 0.24 inches (6 mm) longer than, and weighs 16.5 lbs (7.5 kg) less than, the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: a new compact hydraulic vane-type pump, two patented dog clutches, [3] which replace bulkier conventional clutch packs, and a nested gear set. [2]

  8. Moment of inertia - Wikipedia

    en.wikipedia.org/wiki/Moment_of_inertia

    Here, the function gives the mass density at each point (,,), is a vector perpendicular to the axis of rotation and extending from a point on the rotation axis to a point (,,) in the solid, and the integration is evaluated over the volume of the body . The moment of inertia of a flat surface is similar with the mass density being replaced by ...

  9. Android (operating system) - Wikipedia

    en.wikipedia.org/wiki/Android_(operating_system)

    Android does not have a native X Window System by default, nor does it support the full set of standard GNU libraries. This made it difficult to port existing Linux applications or libraries to Android, [ 213 ] until version r5 of the Android Native Development Kit brought support for applications written completely in C or C++ .
