Box braids are a type of hair-braiding style that is predominantly popular among African people and the African diaspora. This type of hairstyle is a "protective style" (a style which can be worn for a long period of time to let natural hair grow and protect the ends of the hair) and is "boxy", consisting of square-shaped hair divisions.
French curls are box braids done with silky, pre-curled braiding hair. Learn everything you need to know about the look, plus see 14 gorgeous French curl braids looks for inspiration.
Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
Knotless Braids: A variation of box braids, starting with natural hair and gradually adding extensions, reducing scalp tension.Knotless braids do not include the knots. Crochet braids: Extensions are crocheted into cornrowed natural hair, offering a variety of styling options. French braid: A classic braid where hair is braided in three strands ...
The composition of the braids σ and τ is written as στ.. The set of all braids on four strands is denoted by .The above composition of braids is indeed a group operation. . The identity element is the braid consisting of four parallel horizontal strands, and the inverse of a braid consists of that braid which "undoes" whatever the first braid did, which is obtained by flipping a diagram ...
1925 braiding machine in action The smallest braiding machine consists of two horn gears and three bobbins. This produces a flat, 3-strand braid. A braiding machine is a device that interlaces three or more strands of yarn or wire to create a variety of materials, including rope, reinforced hose, covered power cords, and some types of lace.
The spin representations are, in a sense, the simplest representations of Spin(n, C) and Spin(p, q) that do not come from representations of SO(n, C) and SO(p, q). A spin representation is, therefore, a real or complex vector space S together with a group homomorphism ρ from Spin( n , C ) or Spin( p , q ) to the general linear group GL( S ...
A function V gives interaction energy between a set of spins; it is not the Hamiltonian, but is used to build it. The argument to the function V is an element s ∈ Q Z, that is, an infinite string of spins. In the above example, the function V just picked out two spins out of the infinite string: the values s 0 and s 1.
