Summary: This study investigates the effects of waste foundry sand (WFS) on the performance of cement-stabilised macadam (CSM). The results show that the addition of WFS reduces the mixture properties, but can be improved with increasing curing age and cement dosage. The optimum cement dosage is 4%, and the optimum WFS replacement level for natural fine aggregate is 15%.

Summary: This article presents the amplitude and vibrational characteristics of a rotating fiber metal laminated microdisk. The current microstructure is modeled using a two-parameter viscoelastic foundation and the centrifugal and coriolis effects due to rotation are considered. The strains and stresses are determined using the third-order shear deformable theory and the nonlocal strain gradient theory is used to access size-effects. The boundary conditions are derived through governing equations of the laminated rotating microdisk using Hamilton's principle and solved using a numerical method based on the generalized differential quadrature method.

Summary: The study found that in Porous ultra-thin asphalt overlay (PUAO), as the air voids increased, the high-temperature rutting dynamic stability decreased, the tensile strength ratio first decreased and then increased, and the acoustic absorption coefficient gradually increased, but the peak frequency value shifted. The PUAO/AC-13 double-layer specimens showed better performance in dynamic stability and low-temperature bending strength compared to the PUAO single-layer specimens, but had a smaller permeability coefficient. The International Friction Index results showed that PUAO material had excellent skid resistance performance.

Summary: Resilient modulus (M-R) is crucial in the evaluation and design of flexible pavement foundations. Traditional experiment-based methods for determining M-R are time-consuming and expensive. In this study, an extreme gradient boosting-based (XGB) model is proposed to predict the resilient modulus of flexible pavement foundations. The model is optimized using various optimization methods and a large database. The results show that the proposed method accurately predicts the M-R of flexible pavement foundations.

Summary: TiC reinforced Ti-based composite coatings were prepared by laser cladding, and the influence of Y2O3 on the properties and microstructure of the coatings was systematically investigated. Adding 2 wt% Y2O3 completely eliminated cracks and significantly reduced the number of pores in the coatings. The main precipitated phases in the coatings were TiC and 8-Ti. Y2O3 addition inhibited the generation of Ti2Ni at the grain boundary, but promoted the generation of Cr1.93Ti1.07 in the coatings. Dendrites in the coatings became more developed, and a large number of tertiary dendrites were found.

Summary: This study presents an optimization procedure to obtain the optimal dynamic properties of laminated sandwich multiphase nanocomposite truncated conical shell under magneto-hygro-thermal conditions. A novel hybrid optimization method based on particle swarm optimization and harmony search algorithms is proposed to enhance the performance and convergence of optimum dynamic conditions. The hybrid optimization algorithm, HS-PSO, shows superior convergence performance compared to other optimization methods.

Summary: PVA hydrogels with high strength and toughness can be fabricated through dual physical and chemical cross-linking. The best mechanical properties are achieved by reacting at room temperature and subsequently undergoing freeze-thaw and annealing treatment. Additionally, the mechanical properties of PVA hydrogel increase and then decrease with the increase of molecular weight or mass fraction. By changing the reaction solvent, the mechanical properties of PVA hydrogel can be effectively adjusted.

Summary: The use of machine learning techniques in evaluating the integrity of damaged oil and gas pipelines is favored by researchers. Hybrid models, combining the strengths of various constituent models, have been found to outperform standalone models in predicting pipeline integrity. Current research mostly utilizes field data, simulation data, and experimental data, with input characteristics such as temperature, pH, pressure, and velocity being crucial in corroded pipeline integrity assessment.
