The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio ...
The secondary electrons produced during the process of ionization by the primary charged particle are conventionally called delta rays, if their energy is large enough so that they themselves can ionize. [3] Many studies focus upon the energy transferred in the vicinity of the primary particle track and therefore exclude interactions that ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
Hence, even the minimum threshold displacement energy is usually clearly higher than the Frenkel pair formation energy. Each crystal direction has in principle its own threshold displacement energy, so for a full description one should know the full threshold displacement surface T d ( θ , ϕ ) = T d ( [ h k l ] ) {\displaystyle T_{d}(\theta ...
If the sound pressure p 1 is measured at a distance r 1 from the centre of the sphere, the sound pressure p 2 at another position r 2 can be calculated: =. The inverse-proportional law for sound pressure comes from the inverse-square law for sound intensity : I ( r ) ∝ 1 r 2 . {\displaystyle I(r)\propto {\frac {1}{r^{2}}}.}
15-year fixed rate. 6.38%. 10-year fixed rate. 6.25%. 5/1 adjustable rate mortgage ... after which it adjusts to a higher rate and then further adjusts periodically over the remaining life of the ...
At the conclusion of its eighth and final rate-setting policy meeting of the year on December 18, 2024, the Federal Reserve announced it was lowering the federal funds target interest rate by 25 ...
The ROC curve is created by plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold settings. An example of ROC curve and the area under the curve (AUC). The area under the ROC curve (AUC) [1] [2] is often used to summarize in a single number the diagnostic ability of the classifier. The AUC is simply ...
