How does computer aided design help in chemical engineering?
Chemical engineering design problems have evolved in recent years from large scale bulk processes to targeted small batch approaches. As a result, computer aided design is reaching beyond the traditional solutions to classical chemical engineering problems. Take for example, the removal of CO2 from flue gas. The computer aided molecular design framework, CAMD, can be used to identify the ideal ionic liquid for CO 2 removal (Davis et al., 2016). One method that can be used to reduce the computational burden is surrogate modeling. Surrogate models seek to understand input and output relationships that are either unknown or complex via reasonably accurate simpler functions. Many surrogate models have been defined and studied for different applications. Our previous study compared different surrogate modeling approaches in terms of their accuracies using root mean square error (RMSE) and maximum absolute error (MaAE) as the performance metrics. We evaluated the impact of function shape and number of inputs on the accuracies of surrogate model predictions with a sample size of 1,000 data points ( Davis et al., 2017 ). When the results were considered in terms of RMSE, the models developed using Artificial Neural Networks (ANNs) consistently provided the lowest values for all numbers of inputs functions, while the models developed using Automatic Learning of Algebraic Models for Optimization (ALAMO) were comparable to ANN models for functions with four and 10 inputs. When the performance of surrogate model types based on the shape of the challenge functions were considered, ANN models yielded the smallest RMSE for all function shapes. The current work extends these initial comparisons to understand the relationship between the accuracy of the surrogate model and the following characteristics: (1) sampling method; (2) sample size; (3) block-box model shape; and (4) number of inputs. Eight surrogate modeling approaches were used in the analysis. These approaches are: ANN, ALAMO, Extreme Learning Machines (ELM), Support Vector Regression (SVR), Radial Basis Networks (RBN), Gaussian Process Regression (GPR), Random Forests (RF), and Multivariate Adaptive Regression Splines (MARS). A brief overview of these surrogate modeling approaches is provided in Section 2. Training data was generated using thirty-five challenge functions with various surface shapes and number of inputs for each surrogate model. Some brief introductions of the challenge functions are given in Section 3. Each challenge function-surrogate model combination was trained using data generated using three different sampling methods, Latin Hypercube Sampling (LHS), Sobol Sequence and Halton Sequence. The sample size was varied from 50 to 12800, doubling each time. Section 4 provides the procedure for computational experiments. In addition to the surrogate model training and evaluation times, six performance metrics, MaAE, RMSE, Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), R-Squared, and R-Squared Adjusted were calculated for each challenge function and surrogate model combination based on the difference between the true values and the surrogate model predictions using a test set of 100,000 data points generated using the Sobol sampling method. The comparison of surrogate model training and evaluation times, and performance metrics for different sampling methods and surrogate model construction approaches are presented in Section 5. Concluding remarks are given in Section 6.

What is structural analysis in biomedical engineering?
In this process, structural analysis is a critical step in the prediction of fatigue limits and potential failure modalities. Practically, simulation methods are essential since experimental methods often require the creation of expensive, time-intensive prototypes and evaluations. Further, many experimental parameters cannot be directly measured, but can only be computed (e.g., shear stress). Moreover, analytical approaches can only provide a complete solution for simple geometries and loading conditions. In contrast, all biological and biologically derived or inspired materials exhibit pronounced mechanical anisotropy, highly nonlinear stress–strain relationships, large deformations, viscoelasticity, and strong material coupling. Taken as a whole, most biomaterials defy simple material models. Therefore, numerical approaches such as the Finite Element Method (FEM) or the Boundary Element Method (BEM) are more suitable for biomechanical problems. FEM, also known as Finite Element Analysis (FEA), represents the most popular numerical technique to perform stress and strain analysis. Although the approach was originally formulated to perform structural analyses, it has become increasingly adopted in biomechanics and biomaterial sciences to solve complex multi-physics problems. In the following, we present a brief introduction of the mathematical formulation of FEM for the biomaterials audience. We utilize the infinitesimal strain linear elasticity which, while not realistic for most biological materials, allows the basic theory to be presented with maximum clarity.
