Dialysis volume: Kt/V

Indicators of dialysis volume (hemodialysis)

Heat Index (WBGT: Wet Bulb Globe Temperature)

WBGT (Wet-Bulb Globe Temperature) is an index that incorporates three factors—humidity, radiant heat, and air temperature—which significantly affect the human body’s heat balance; it is calculated using the dry-bulb temperature, wet-bulb temperature, and globe temperature.

Expressing the normal vector (Yataka) using classical trigonometric functions

Calculate the values of the trigonometric functions. In older trigonometric functions, terms like "positive slope" are also used to refer to "slope height."

Area of a Quadrilateral (Application of Heron's Formula)

If the sum of a pair of diagonals is known, Bretschneider's formula can be used, but here we are using only "length information."

Differential expansion between the front and back surfaces due to board warping

When a board is warped, calculate the difference in expansion between the top and bottom surfaces.

Warpage Calculated from the Expansion Difference Between the Front and Back Sides of a Board

Calculate the warpage that occurs when a flat plate experiences a difference in expansion between its top and bottom surfaces.
