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.
1 Stratified signifies two or more layers of epithelial cells. 2  By convention, a stratified epithelium is described according to the shape of cells on its free surface. 3  Regardless of whether the surface cells are squamous, cuboidal, or columnar, the underlying cells are usually cuboidal. Within the epithelium, the narrow spaces between cells are sealed off from the external environment by cell junctions near the free surface of the cells. 2  Compared to ordinary connective tissue, epithelial tissue has very little interstitial fluid. 3  Epithelial tissue is polarized.
