In this formula, "A," is, again, the area, "r" represents the radius (half the distances from one side of the circle to the other), andπis a Greek letter pronounced "pi," which is 3.14 (the ratio of a circle’s circumference to its diameter). Practical Applications There are many...
Euler’s book ofEssay Explaining the Properties of Airin 1727, he started using the single-letterπwith the value of pi being equal to 6.28. Nevertheless, his first use ofπ= 3.14 can be dated back to 1736 in hisMechanicain 1736. In 1748, he wrote “for the sake of brevity we will ...

Understanding what is important and redundant within data can improve the modelling process of neural networks by reducing unnecessary model complexity, training time and memory storage. This information is however not always priorly available nor trivia
Quantum hardware has the potential to efficiently solve computationally difficult problems in physics and chemistry to reap enormous practical rewards. Analogue quantum simulation accomplishes this by using the dynamics of a controlled many-body system to mimic those of another system; such a method is...
(t)=\int^{t}_{-\infty}\frac{1}{\sqrt{2\pi}}\exp\left\{-\frac{y^2}{2}\right\}\mathrm{d}y,\\即\\\displaystyle \hat{\Phi}_{t}=\dfrac{1}{n}\sum_{i=1}^{n}\mathbb{I}\{x_i\leq t\},\\这里\{x_i\}_{i=1:n}\overset{\mathrm{i.i.d.}}\sim\mathcal{N}(0,...
Frequently, only certain marginals of this full posterior density are of interest; thus an interesting problem is how to estimate the marginal posterior densities based on the dependent observations {Theta(i), 0 less than or equal to i less than or equal to n} from pi(theta\\data). We ...
In this paper, we collect and combine the traffic flow variables from the multi-source sensors, and propose a PITED method based on Random Forest (RF) and Permutation importance (PI) for traffic event detection. This model selects the suitable traffic flow variables by means of permutation ...
Because the width of the eight running bands (d) is slightly different for each stone, we define the surface roughness area (SRA) for each running band using Eq. (8): $$SRA={ R}_{\mathrm{a}} A = {\pi R}_{\mathrm{a}} \left(\overline{r}_{2}^{\ \ 2}-\overline{r}_{1...
