  2. Paraphrase - Wikipedia

    en.wikipedia.org/wiki/Paraphrase

    Paraphrase. A paraphrase or rephrase ( / ˈpærəˌfreɪz /) is the rendering of the same text in different words without losing the meaning of the text itself. [ 1] More often than not, a paraphrased text can convey its meaning better than the original words. In other words, it is a copy of the text in meaning, but which is different from the ...

  4. Free-piston engine - Wikipedia

    en.wikipedia.org/wiki/Free-piston_engine

    Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).

  5. Word2vec - Wikipedia

    en.wikipedia.org/wiki/Word2vec

    v. t. e. Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words. The word2vec algorithm estimates these representations by modeling text in a large corpus. Once trained, such a model can detect ...

    A long sentence completion test is the Forer Sentence Completion Test, which has 100 stems. The tests are usually administered in booklet form where respondents complete the stems by writing words on paper.

  8. Micro hydro - Wikipedia

    en.wikipedia.org/wiki/Micro_hydro

    Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. [ 1] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net ...

  9. Linear compressor - Wikipedia

    en.wikipedia.org/wiki/Linear_compressor

    A linear compressor is a gas compressor where the piston moves along a linear track to minimize friction and reduce energy loss during conversion of motion. This technology has been successfully used in cryogenic applications which must be oil-less. The suspension spring can be flexure type or coil type. An oil-free valved linear compressor ...
