Dimension, vector, space, Lebesgue, covering, Inductive, Hausdorff, Fractal dimension, Space-filling curve, Dimension, Hyperspace In mathematics and physics, the dimension of a space or object is informally defined as the minimum number of coordinates needed to specify each point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it. Cubes, cylinders and balls are three-dimensional. The concept of dimension is not restricted to physical objects. High-dimensional spaces occur in mathematics and the sciences for many reasons, frequently as configuration spaces such as in Lagrangian or Hamiltonian mechanics; these are abstract spaces, independent of the physical space we live in. The state-space of quantum mechanics is an infinite-dimensional function space. Some physical theories are also by nature high-dimensional, such as the 4-dimensional general relativity and higher-dimensional string theories.

Предлагаемая книга освещает наиболее часто встречающуюся патологию желудочно-кишечного тракта, печени, поджелудочной железы, в диагностику которой существенный вклад вносит компьютерная томография. Представленный материал основан на многолетних собственных наблюдениях авторов и многочисленных литературных источниках последних лет. Большое внимание уделено применению контрастного усиления как...
