Hace 7 horas · The Plasma-Rotating Electrode Process, often abbreviated as PREP, is a fascinating and highly specialized method for producing high-quality metal powders.This process, which involves a rotating electrode and a plasma arc, creates powders that are essential for various high-performance applications, including additive manufacturing, aerospace, and biomedical implants.
Hace 1 día · Narayana gives a method to construct all the pan-magic squares of fourth order using knight's move; enumerates the number of pan-diagonal magic squares of order four, 384, including every variation made by rotation and reflection; three general methods for squares having any order and constant sum when a standard square of the same order is known; two methods each for constructing evenly even ...
Hace 1 día · The roads were state-funded and maintained, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower became president in 1953, his administration developed a proposal for an interstate highway system, eventually resulting in the enactment of the Federal-Aid Highway Act of 1956 .
Hace 7 horas · Vector addition and scalar multiplication: a vector v (blue) is added to another vector w (red, upper illustration). Below, w is stretched by a factor of 2, yielding the sum v + 2w. In mathematics and physics, a vector space (also called a linear space) is a set whose elements, often called vectors, may be added together and multiplied ("scaled") by numbers called scalars.
