In most industrial processes, both autocorrelations and cross correlations in the data need to be extracted for purpose of process monitoring diagnosis. However, traditional dynamic modeling methods focus on relationship while are at best implicit. this brief, a new autoregressive latent variable model is proposed capture static relationships simultaneously. The method rather general which can improve performance monitoring. Kalman filter smoother employed inference parameters estimated with...
Abstract The Woodbury formula is an efficient tool in mathematics to calculate low‐rank perturbation problems and has been applied improve the computational efficiency of nonlinear seismic response analysis (NSRA) structures with local nonlinearity. Using for NSRA can avoid time‐consuming recalculation factorization large‐dimensional global stiffness matrix a structure by only solving small‐dimensional Schur complement system representing nonlinearity per iteration. Because dimension...
Abstract Inversion of surface‐wave free fields is great importance in providing seismic excitations for the finite element (FE) analysis soil–structure interaction (SSI) systems. In case layered media, propagating surface waves are characterized by their unique dispersion property, resulting dispersive multi‐mode wavefields. Available studies primarily focus on only fundamental mode and neglect influence higher modes, which fail to identify real structural response characteristics. To...
Selective catalytic reduction of nitrogen oxides (NOx) with ammonia (NH3–SCR) is an efficient NOx strategy, while the denitrification (deNOx) catalysts suffer from serious deactivation due to coexistence multiple poisoning substances, such as alkali metal (e.g., K), SO2, etc., in industrial flue gases. It essential understand interaction among various poisons and their effects on deNOx process. Herein, ZSM-5 zeolite-confined MnSmOx mixed (MnSmOx@ZSM-5) catalyst exhibited better performance...
This paper presents an innovative re-centering deformation-amplified shape memory alloy damper (RDASD) to reduce the responses of civil structures under earthquake motions. The can amplify displacement deformation according actual needs and fully exploit energy dissipation capacity superelastic materials. Cyclic tensile-compressive tests fabricated RDASD are conducted study influence amplitude loading rate on damper's mechanical properties. Additionally, a theoretical model that precisely...
The simultaneous estimation and variable selection for Cox model has been discussed by several authors when one observes right-censored failure time data. However, there does not seem to exist an established procedure interval-censored data, a more general complex type of except two parametric procedures. To address this, we propose broken adaptive ridge (BAR) regression that combines the strengths quadratic regularization weighted bridge shrinkage. In particular, method allows number...
The structural efficiency of stiffened panels can be significantly improved by utilizing curvilinear stiffeners because their outstanding design flexibility. However, the explosion variables poses a stiff challenge to layouts such structures. In this study, novel layout optimization method is proposed for curvilinearly based on deep learning-based models, which enables intelligent design. Unlike traditional methods, image-based layout, characteristic stiffener paths, employed as variable,...
Mechanical metamaterials are artificial materials with unique global properties due to the structural geometry and material composition of their unit cell. Typically, mechanical metamaterial cells designed such that, when tessellated, they exhibit as zero or negative Poisson's ratio stiffness. Beyond these applications, can be used achieve tailorable nonlinear deformation responses. Computational methods gradient-based topology optimization (TO) size/shape (SSO) implemented design...
The performance of a semi-active suspension depends on the quality control algorithm. Considering limitations conventional PID controllers within intricate nonlinear systems, such as imprecise parameter tuning and deterioration, we introduced fractional-order (FOPID) strategy for vehicle suspension, this approach amalgamates theory with to enhance both controllable scope precision system. Research was conducted using dynamic model quarter vehicle. Simulations analyses were performed...

The sudden decline in the attitude control performance is a common abnormal situation during shield tunneling. When problem happens, driver will have difficulty controlling shield's attitude, which cause to deviate from its design axis and affect quality of tunnel. causes behind poor are usually complicated, so how choose appropriate countermeasures challenging problem. Based on above issues, this paper proposes Interpretable Predictive Model for Shield Control Performance (IPM_SCP). model...
