  2. Layering - Wikipedia

    en.wikipedia.org/wiki/Layering

    Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted.

  3. Transfer-matrix method (optics) - Wikipedia

    en.wikipedia.org/wiki/Transfer-matrix_method...

    Propagation of a ray through a layer. The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films. [1] [2] This is, for example, relevant for the design of anti-reflective coatings and dielectric mirrors.

  4. Propagation of grapevines - Wikipedia

    en.wikipedia.org/wiki/Propagation_of_grapevines

    The most common ways to perform field grafting are the Chip Bud method, the T Bud method, the Cleft Graft and the Bark Graft. [5] [8] The Chip Bud Method is performed shortly after the grape vine is planted, giving the rootstock enough time to become active but the bud of the grape vine is still inactive. It is performed by cutting two small ...

  5. Radio propagation - Wikipedia

    en.wikipedia.org/wiki/Radio_propagation

    Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]

  6. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.

  7. Monte Carlo method for photon transport - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method_for...

    Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of photon movement between sites of photon-matter interaction and the angles of deflection in a photon's trajectory when a scattering event occurs.

  8. Fruit tree propagation - Wikipedia

    en.wikipedia.org/wiki/Fruit_tree_propagation

    The new plant is severed only after it has successfully grown roots. Layering is the technique most used for propagation of clonal apple rootstocks. The most common method of propagating fruit trees, suitable for nearly all species, is grafting onto rootstocks. This in essence involves physically joining part of a shoot of a hybrid cultivar ...

  9. Two-ray ground-reflection model - Wikipedia

    en.wikipedia.org/wiki/Two-ray_ground-reflection...

    From the figure the received line of sight component may be written as = {() /}and the ground reflected component may be written as = {() (+ ′) / + ′}where () is the transmitted signal, is the length of the direct line-of-sight (LOS) ray, + ′ is the length of the ground-reflected ray, is the combined antenna gain along the LOS path, is the combined antenna gain along the ground-reflected ...
