In mathematics, generalized means are a family of functions for aggregating sets of numbers, that include as special cases the Pythagorean means (arithmetic, geometric, and harmonic means). The generalized mean is also known as power mean or Hoelder hÃ¶lder (mean named After Otto). hoelder hÃ¶lderf p is a non-zero real number, and are positive real numbers, then the generalized mean or power mean with exponent p of these positive real numbers is: Note the relationship to the p-norm.
exists and is an alternate of . Epithelial tissues are classified according to two characteristics: the arrangement of cells into layers and the shapes of the cells.
Epithelial tissue comprises one of the four basic tissue types. The others are connective tissue (support cells, immune cells, blood cells), muscle tissue (contractile cells), and nervous tissue. Organs represent various combinations of these four basic tissue types, which thus comprise the entire body. Each tissue type retains its fundamental character wherever it occurs.
