Chernoff faces, invented by applied mathematician, statistician, and physicist Herman Chernoff in 1973, display multivariate data in the shape of a human face. The individual parts, such as eyes, ears, mouth, and nose represent values of the variables by their shape, size, placement, and orientation.
"You could see a diamond-shaped face, and someone else would call it an oblong face," says Dr. Tripathi. "There's a more gaunt temple area, more width to the mid-face, and then a narrower lower ...
Similarly, a k-isohedral tiling has k separate symmetry orbits (it may contain m different face shapes, for m = k, or only for some m < k). [ 6 ] ("1-isohedral" is the same as "isohedral".) A monohedral polyhedron or monohedral tiling ( m = 1) has congruent faces, either directly or reflectively, which occur in one or more symmetry positions.
Within economics, this has often been presented as the foundation of a bartering economy. [3] In principle, double coincidence of wants would mean that both parties must agree to sell and buy each commodity. Under this system, problems arise through the improbability of the wants, needs, or events that cause or motivate a transaction occurring ...
Using mild soap on well-seasoned cast-iron cookware will not damage the seasoning. [41] This is not because modern soaps are gentler than older soaps. [42] Kappa-maki contains cucumber and no seafood. Sushi does not mean raw seafood; some sushi, such as kappamaki, contains no seafood. The word refers to the vinegar-prepared rice the dish ...
These fighters are commonly referred to as having a "granite chin", an "iron chin", or similar. Generally, the jaw portion of the skull, and specifically the point of the chin, is the area most vulnerable to a knock-out blow and therefore having an exceptional tolerance to punishment in this area is a great advantage to a fighter.
Increasingly common is the camlock arrangement, in which shaped studs and cams replace threaded studs for rapid exchanging of the faceplate with other accessories, such as three or four jaw chucks. The faceplate was the ancestor of lathe chucks, an arrangement of three or more adjustable 'dogs' bolted to the faceplate providing a primitive ...
Mien shiang (Chinese: 面 相; pinyin: miànxiàng meaning face (mien) reading (shiang)) is a physiognomic and fortune-telling practice in Chinese culture and traditional Chinese medicine which purports to determine aspects of person's character, personality, and (future) health by analyzing their face according to the five phases ("wu xing").
