RC shear walls are commonly used as lateral load-resisting elements in seismic regions, and the estimation of their strengths can become simultaneously design-critical complex when they have so-called squat geometries, i.e., height-to-length ratios less than two. This paper presents a study on training interpretation an advanced machine-learning model that strategically combines two algorithms for said purpose. To train model, comprehensive strength database 434 samples is utilized. First,...
A functional structure of Mn0.5Zn0.5Fe2O4-on-polyaniline nanocomposites with high dielectric absorbing properties and electromagnetic shielding effectiveness at low frequencies was successfully fabricated through a facile in situ emulsion polymerization. Polyaniline (PANI) doped hydrochloric acid to improve its electrical interactions ferrite nanoparticles. The electrostatic force, paramagnetic force hydrogen bonding strongly bonded or assembled nanoparticles on the polyaniline surface...
Abstract Current research on quadrotor modeling mainly focuses theoretical analysis methods and experimental methods, which have problems such as weak adaptability to the environment, high test costs, long durations. Additionally, PID controller, is currently widely used in quadrotors, requires improvement anti-interference. Therefore, aforementioned has considerable practical significance for controller design of quadrotors with strong coupling nonlinear characteristics. In present...
In order to explore the applicability of waste engine oil and cooking used in aged asphalt, effect on asphalt recycling was studied through analysis improvement its physical, chemical, rheological properties. Six binders with different aging times were obtained by indoor test simulation using Thin Film Oven Test at 163 °C. Then, five dosages added investigate performances. The results clearly demonstrated that could soften recover work ability effectively. Furthermore, performances six...
With global warming and the depletion of fossil energy sources, renewable is gradually replacing non-renewable as main in future. As one fastest growing safety reliability wind have been paid more attention. The size modern turbines becoming larger larger. component to capture energy, blade often damaged by various complex environments irregular loads. Therefore, health monitoring damage identification turbine blades become a research focus. At present, addition overview detection methods...
The stable polymeric nitrogen and polynitrogen compounds have potential applications in high-energy-density materials. For beryllium nitrides, there is one known crystalline form, Be3N2, at ambient conditions. In the present study, structural evolutionary behaviors of polynitrdes been studied up to 100 GPa using first-principles calculations unbiased structure searching method combined with density functional calculations. One stoichiometry beyrllium polynitride has theoretically predicted...
Nano-scale zero-valent iron (nZVI) is among the most common nanoparticles widely used for treatment of various environmental contaminants. However, little known about combined effects nano-zero-valent and other soil amendments on remediation plant performance. For first time, we studied Cr(VI)-contaminated using bare nZVI (B-nZVI) starch-supported (S-nZVI) in combination with either biochar (BC) or humic acid (HA), consequent growth Cr accumulation. Both S-nZVI B-nZVI decreased contents...
Due to the dual nature of metal and fluid, gallium‐based liquid metals with a low melting point at or around room temperature have gained growing interest recently. Although more properties gallium are developed, their intrinsic not able meet increasing requirement from scientific industrial community. To broaden its applications, many kinds composites prepared applied in cutting‐edge fields like biomedical engineering, flexible robots, heat management, so on. summarize latest progress...
The diffuser plays a significant role in the performance of centrifugal pump, especially for high-power pump. Therefore, to improve efficiency optimization vaned is proposed this work. steady simulations were carried out by solving three-dimensional Reynolds-averaged Navier–Stokes equations with shear stress transport turbulence model. numerical head and validated experimental results original show that predicted simulation good agreement results. Four design variables including inlet...
With the continuous warming of global climate, expanding use renewable energy has become one main social responsibilities. However, as number installed wind turbines and their physical dimensions continue to increase, issue generated noise increasingly significant in influencing acceptance endorsement power projects by neighboring communities. In this paper, we investigated two turbine units with rated powers 1.5 MW 4.5 analyzed variations low-frequency during operation shutdown periods....
