Body surface area. In physiology and medicine, the body surface area ( BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the ...
Time-domain reflectometer for cable fault detection. A time-domain reflectometer ( TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses . It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable ), [ 1] and to locate ...
The following table of United States cities by crime rate is based on Federal Bureau of Investigation Uniform Crime Reports (UCR) statistics from 2019 for the 100 most populous cities in America that have reported data to the FBI UCR system. [1] The population numbers are based on U.S. Census estimates for the year end.
The Poisson distribution is an appropriate model if the following assumptions are true: k is the number of times an event occurs in an interval and k can take values 0, 1, 2, ... . The occurrence of one event does not affect the probability that a second event will occur. That is, events occur independently.
Impact event. Damage to trees caused by the Tunguska event. The object, just 50–80 metres (150–240 feet) across, exploded 6–10 km (4–6 miles) above the surface, shattering windows hundreds of km away. An impact event is a collision between astronomical objects causing measurable effects. [1]
A discrete signal or discrete-time signal is a time series consisting of a sequence of quantities. Unlike a continuous-time signal, a discrete-time signal is not a function of a continuous argument; however, it may have been obtained by sampling from a continuous-time signal. When a discrete-time signal is obtained by sampling a sequence at ...
Tempel 1 (official designation: 9P/Tempel) is a periodic Jupiter-family comet discovered by Wilhelm Tempel in 1867. It completes an orbit of the Sun every 5.6 years. Tempel 1 was the target of the Deep Impact space mission, which photographed a deliberate high-speed impact upon the comet in 2005. It was re-visited by the Stardust spacecraft on ...
