  2. Light verb - Wikipedia

    en.wikipedia.org/wiki/Light_verb

    The light verbs are underlined, and the words in bold together constitute the light verb constructions. Each of these constructions is the (primary part of the) main predicate of the sentence. Note that the determiner a is usually NOT part of the light verb construction. We know that it is not part of the light verb construction because it is ...

  3. Immediate constituent analysis - Wikipedia

    en.wikipedia.org/wiki/Immediate_constituent_analysis

    A sentence, in turn, is formed as a sequence of symbols, beginning with a designated non-terminal symbol and culminating in a terminal string. Every terminal node is part of a constituent, as constituents form the interconnected structure leading from the root to the smallest, indivisible unit of the tree.

  4. Three-point lighting - Wikipedia

    en.wikipedia.org/wiki/Three-point_lighting

    The addition of a fourth light, the background light, makes for a four-point lighting setup. The background light is placed behind the subject(s), on a high grid, or low to the ground. Unlike the other three lights, which illuminate foreground elements like actors and props, it illuminates background elements, such as walls or outdoor scenery.

  5. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity.

  6. Immersion lithography - Wikipedia

    en.wikipedia.org/wiki/Immersion_lithography

    The lenses in the highest resolution "dry" photolithography scanners focus light in a cone whose boundary is nearly parallel to the wafer surface. As it is impossible to increase resolution by further refraction, additional resolution is obtained by inserting an immersion medium with a higher index of refraction between the lens and the wafer.

  7. Wh-movement - Wikipedia

    en.wikipedia.org/wiki/Wh-movement

    In the wh-movement, there are additional segments that are added: EPP (extended projection principle) and the Question Feature [+Q] that represents a question sentence. The wh-movement is motivated by a Question Feature/EPP at C (Complementizer), which promotes movement of a wh-word from the canonical base position to Spec-C.

  8. Stress (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Stress_(linguistics)

    The stress placed on words within sentences is called sentence stress or prosodic stress. That is one of the three components of prosody , along with rhythm and intonation . It includes phrasal stress (the default emphasis of certain words within phrases or clauses ), and contrastive stress (used to highlight an item, a word or part of a word ...

  9. Phosphorescence - Wikipedia

    en.wikipedia.org/wiki/Phosphorescence

    In a modern, scientific sense, the phenomena can usually be classified by the three different mechanisms that produce the light, [further explanation needed] and the typical timescales during which those mechanisms emit light. Whereas fluorescent materials stop emitting light within nanoseconds (billionths of a second) after the excitation ...
