\underline{\textbf{Theorem. Ito Formula w.r.t. Ito Process.}} If X is Ito process, f\in C^{1,2}, then f(t,X_t)=f(0,0)+\int_0^tf_t(u,X_u)du+\int_0^t f_x(u,X_u)dX_u+\frac{1}{2}\int_0^t f_{xx}(u,X_u)d[X,X]_u \underline{Remark.} if f\in C^2...

It is not a global convergence algorithm and the evolutionary formula of speed and position of PSO leads to low randomness and intelligence [119]. To overcome these, Huang et al. [103] apply a quantum-behaved PSO algorithm for the first time to the mapping problem, which converges faster ...

The Sullivan method (in which health expectancies are calculated from simple formulae using lifetables) is useful for comparing different time points as it is not subject to attrition, but the approach relies on production of life tables and is therefore restricted in the subgroups it can compare...
We selected several common evaluation indicators to evaluate our network segmentation performance, including F1-Score, IOU, and G-mean score44. In addition, we compared the number of parameters and FLOPs with baselines. The formula of IOU is: ...
This research intends to investigate the application of the adaptive local mean decomposition (ALMD) algorithm in extracting the suitable characteristics for DC series arc fault detection in PV systems. The ALMD algorithm is a novel self-adaptive time–frequency analysis method, which is particularly ...
The harmonic mean is represented by the following formula: 𝐻=2×Accs×AccuAccs+AccuH=2×Accs×AccuAccs+Accu (15) To further measure the performance of the model, we also introduce three metrics that are model parameters (Params), model running time (Time, in seconds), and floating-...
Fig. 5.1.15 shows the simple formulae that can be applied to use the finite element model defined stresses to determine membrane (σmembrane) and bending (σbending) stresses. The two sections “B-B” and “D-D” should represent the planes of maximum normal stress and are close to the...
