Image tracingIn computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics. An image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. While such an image is useful, it has some limits. If the image is magnified enough, its artifacts appear. The halftone dots, film grains, and pixels become apparent. Images of sharp edges become fuzzy or jagged. See, for example, pixelation.
Patent claimIn a patent or patent application, the claims define in technical terms the extent, i.e. the scope, of the protection conferred by a patent, or the protection sought in a patent application. In other words, the purpose of the claims is to define which subject-matter is protected by the patent (or sought to be protected by the patent application). This is termed as the "notice function" of a patent claim—to warn others of what they must not do if they are to avoid infringement liability.
PharyngalisationLa pharyngalisation est un trait d'articulation secondaire des sons d'une langue. Ce trait, comme beaucoup d'autres articulations secondaires, est considéré comme un trait accompagnant les voyelles. On le trouve fréquemment associé aux consonnes, dans des langues telles que l'arabe (tous les dialectes de l'arabe n'utilisent pas cette articulation). On trouve dans les manuels d'arabe le terme de consonne emphatique. Dans cette langue, on oppose les consonnes « simples » et leur variante « emphatique ».
Shin (letter)Shin (also spelled Šin (DIN) or Sheen) is the twenty-first letter of the Semitic abjads, including Phoenician šīn , Hebrew šīn ש, Aramaic šīn , Syriac šīn ܫ, and Arabic sin س. Its sound value is a voiceless sibilant, ʃ or s. The Phoenician letter gave rise to the Greek Sigma () (which in turn gave Latin S and Cyrillic С), and the letter Sha in the Glagolitic and Cyrillic scripts (, ). The South Arabian and Ethiopian letter Śawt is also cognate.
