quarantined (magenta) and hospitalized requiring ICUs (red) averaged over 10,000 simulations with parameters sampled using a Latin Hypercube technique (see Methods) around their nominal values set as those estimated in the last time window for each region as reported...
The mathematical method of RSA is used to establish a proxy modeling for the above design points. Finally, a multi-objective optimization algorithm is used to optimize the design variables within the design range, so as to obtain the Pareto optimal frontier solution set. We randomly selected a ...
conditions by using the Latin Hypercube Sampling(LHS).The Spearman partial(rank) correlation coefficient and the standard(rank) regression coefficient are adopted to analyze the parameter sensitivity.The results indicate that LHS is an effective method for the stochastic analysis of groundwater flow ...
拉丁超立方抽样初始化:CHAM算法使用拉丁超立方抽样(Latin Hypercube Sampling)来初始化种群,从而提高初始种群的质量。 基于层次协作机制的位置更新策略:CHAM算法提出了一种基于层次协作机制的位置更新策略,该策略在算法的不同迭代阶段实现不同的更新方法,有效地避免了算法陷入局部最优。 消融研究:论文中的消融研究表明,混...
For a sampling of the biokinetic parameters, the Latin hypercube sampling method (LHS) (Iman and Shorten- carier 1984) was used. To generate the samples this tech- nique requires minimum and maximum values and the Table 2 Surrogate organs Target organ Breast Salivary glands Endosteum ...
In the second stage, Latin hypercube sampling (LHS) is applied in the local shape optimization of the PDE surface patches determined by the optimized framework to improve local details. The effectiveness of our proposed method is demonstrated by better aerodynamic performance achieved from the ...
Furthermore, the Latin Hypercube Sampling method has been utilized to manage the uncertainties. In addition, a penalty function and a power exchange pricing model are evaluated by the electrical marginal price of each microgrid to determine the agreed power exchange among the MEMGs. The suggested ...
measures the monotonic relationship between an input parameter and the output variable when the linear effects of other independent variables are discounted16. The input parameters were\(\epsilon , \xi , \nu ,\)and\(\psi \); and they were sampled using the Latin Hypercube Sampling method. ...
