An intensity-duration-frequency curve (IDF curve) is a mathematical function that relates the intensity of an event (e.g. rainfall) with its duration and frequency of occurrence. [1] Frequency is the inverse of the probability of occurrence. These curves are commonly used in hydrology for flood forecasting and civil engineering for urban ...
Time of concentration is useful in predicting flow rates that would result from hypothetical storms, which are based on statistically derived return periods through IDF curves. [ 4 ] [ 5 ] For many (often economic) reasons, it is important for engineers and hydrologists to be able to accurately predict the response of a watershed to a given ...
The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.

youtube-dl -F <url> The video can be downloaded by selecting the format code from the list or typing the format manually: youtube-dl -f <format/code> <url> The best quality video can be downloaded with the -f best option. Also, the quality of the audio and video streams can be specified separately and merged with the + operator. [34]
The Wasserman 9-Panel Plot is named for American physiologist Professor Karlman Wasserman M.D. Ph.D., who first displayed the data in this manner. [3] Professor Wasserman worked extensively on pulmonary physiology, and also described the "gear wheel model" used for explaining results obtained from the test.
Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...
