Passive daytime radiative cooling (PDRC) has drawn significant attention recently for electricity-free cooling. Porous polymers are attractive PDRC since they have excellent performance and scalability. A fundamental question remaining is how depends on pore properties (e.g., radius, porosity), which critical to guiding future structure designs. In this work, optical simulations carried out answer question, effects of size, porosity, thickness studied. We find that mixed nanopores radii 100...
Visibly transparent radiative cooling (VTRC) shows great potential in energy-saving buildings or car glasses for lighting and cooling. How to balance the performance is of significance VTRC. In addition, thermal on inner side should also be determined Here, we designed a Janus VTRC coating consisting emitter, PDMS, near-infrared reflector, TiO2/Ag/TiO2. On outer side, visible transmittance T̅vis = 0.70, while solar reflectance R̅solar 0.40, emittance atmospheric window ε̅LWIR 0.94 can...
This research analyzes the fatigue behaviours of asphalt mixture under haversine wave and two more realistic loading waveforms induced by single axle tandem axles, based on pseudo-strain-based approaches. It is found that lives single-axle are higher than those wave, while tandem–axle generates lowest life. fact suggests testing using actual waves occurring in field to improve life prediction layer. Three PSE-related indicators, namely initial dissipated PSE, cumulative PSE average changing...
The subjective perceptions of passengers are intricately linked to the noise levels in subway stations urban rail transit systems. In this study, comprehensive measurement was conducted on environment platforms during operational hours at four distinct types within an metro network. To ensure precise data collection, different and sound pressure points were strategically positioned middle both ends each station platform. Subsequently, platform continuously monitored throughout operation...
The oxidative aging of asphalt binder affects the long-term performance flexible pavement. Apart from intrinsic property binder, in an mixture is also affected by mixture’s oxygen transport efficiency, which can be characterized diffusion coefficient. In this study, coefficients ( D s ) compacted mixtures different designs were determined. same samples aged one dimension for a relatively long period time. Asphalt binders slices specimens extracted and recovered, their states Influences air...
Ballast mats are considered as an effective solution for reducing vehicle-induced vibrations. However, the research on vibration characteristics of each part ballasted track with a ballast mat is limited. In this study, reduction effects evaluated by numerical and experimental analysis using wheelset drop tests. A three-dimensional model consisting wheel, contact between them built rigid–flexible coupling method. The accuracy verified comparison finite element in terms receptance phase...
Abstract In this study, phosphogypsum (PG) is simulated by doping fluorine and phosphorus ions in an analytically pure reagent of gypsum dihydrate. The influence impurity content on the dehydration reaction process its crystalline micromorphology assessed during preparation α‐type hemihydrate reversed‐phase microemulsion system mechanism. results show that when increases from 0 to 1.0 mol L −1 (ωNaF = ), dihydrate will be greatly slowed down.

Rutting of asphalt pavement is a major issue that affects its serviceability in hot climate. Grouted macadam (GM) has been used as an alternative material to tackle rutting problems, thanks high stiffness. Yet, GM possesses some advantageous properties pavements attributed the contained binders. Although ordinary Portland cement (OPC) can be grouting for GM, using OPC needs long period time develop full strength even if admixtures are added early development. Consequently, premature damage...
With the deep development of tight sand gas reservoirs, problems such as short stable production period and quick decline wells after fracturing have become increasingly prominent. Consequently, there is an increasing demand for effective penetration conductivity artificial fractures. Impulse technology introduces a concept discrete multilayer sanding inside fractures; joint application pulse blender which can be switched at high frequency, intensive multi-cluster perforation special fibrous...
Effective vibration recognition can improve the performance of control and structural damage detection is in high demand for signal processing advanced classification. Signal-processing methods extract potent time-frequency-domain characteristics signals; however, conventional characteristics-based classification needs to be improved. Widely used deep learning algorithms (e.g., convolutional neural networks (CNNs)) conduct by extracting high-dimensional data features, with outstanding...
