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 which is only one cell thick is known as simple epithelium. If it is two or more cells thick such as the skin, it is known as stratified epithelium. Simple epithelium Simple epithelium can be subdivided according to the shape and function of its cells.Squamous (pavement) epithelium.Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium.olumnar epithelium forms the lining of the stomach and intestines. Some columnar cells are specialised for sensory reception such as in the nose, ears and the taste buds of the tongue. Goblet cells (unicellular glands) are found between the columnar epithelial cells of the duodenum.
