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) Epithelial Tissue. Epithelial tissue forms the covering or lining of free body surfaces, both internal and external. For example, the outer layer of the skin is formed from epithelial tissue as are the inner linings of the digestive tract and blood vessels.As a group, epithelial tissues perform a variety of functions, including protection, absorption, excretion, secretion and lubrication.I ANIMAL TISSUES. In animals, organs are composed of varying combinations of four basic tissue types -- epithelial tissue, connective tissue, muscle tissue and nervous tissue. Each of these tissues has distinctive structural features and specific functions which are again combined to produce functioning organs.
