Abstract Numerous tidal phenomena, including river tides, internal and tides in ice‐covered bay, are nonstationary, which pose a great challenge for traditional analysis methods. Based on the independent point scheme cubic spline interpolation, new approach, namely enhanced harmonic analysis, is developed to deal with nonstationary tides. A MATLAB toolbox, S_TIDE, from widely used T_TIDE, realize approach. The efficiency of S_TIDE validated by analyzing set hourly water level observations...
Abstract The two‐step method for perovskite solar cells (PSCs) offers a promising technology scalable manufacturing, particularly under ambient air conditions, due to its inherent simplicity, high reproducibility, and operational convenience. With this approach, achieving high‐quality of lead iodide (PbI 2 ) films during the initial stage is paramount ensuring overall performance stability devices. However, fabrication PbI , residual boiling point hygroscopic dimethyl sulfoxide (DMSO)...

This study employed friction and wear experiments on nitrocarburized HT250 gray cast iron, utilizing GCr15 cemented carbide balls as the pair, to investigate behavior mechanism of compound layer, diffusion matrix. The findings indicate that layer exhibits highest resistance, followed by while matrix shows lowest resistance. At lower loads, form is characterized minor flaking wear, abrasive displays adhesive accompanied wear. With increasing transitions fatigue demonstrates severe...
Summary This paper presents an efficient topology optimization procedure for exterior acoustic‐structure interaction problems, in which the coupled systems are formulated by boundary element method (BEM) and finite (FEM). So far, based on FEM‐BEM still faces several issues needed to be addressed, especially design sensitivity analysis systems. In this work, we contribute these two main aspects. Firstly, adjoint variable (AVM) formulations derived of arbitrary objective function, feedback...

This paper presents a numerical approach to simulate sliding friction between engineering surfaces with 3D roughness in point contacts. The is developed on the basis of deterministic solutions mixed lubrication, which able predict locations where asperity contacts occur, and pressure distribution over both lubrication contact areas. If coefficients contacting asperities have been determined, total force can be calculated by summing up two components, i.e., boundary contributed shear stress...
