Vulcanized, foamed latex rubber features high density of intercommunicated cells and controlled elastomeric properties, rendering wide applications from elastic sponges to rubbery coatings. This provides an emergent incentive for properly recycling, devulcanizing reusing the waste (WLR). Here, a microwave-assisted devulcanization (MAD) approach was disclosed cleave cross-links without severe rupture backbone chains, strategically involving use hydrothermal reaction at 180 °C several minutes...
The strength-ductility trade-off behaviors for most metallic alloys are intrinsically depend on various microstructures formed during materials processing. Thermodynamics and kinetics of the involved phase transformation concurrent/subsequent deformation play important roles in determining overall final performances. Since mechanical responses aluminum can be mediated by introduction nano-sized precipitates, taking heat-treatable Al–Mg–Si as representative, we herein investigate from...
Dislocation core dominates dislocation mobility and mechanical properties of crystalline solids. To date, a complete landscape for describing with narrow in aluminum (Al) remains elusive, thus deformation mechanisms Al alloys are still unclear. This work investigates the structure behaviors alloyed solutes X (X = Mg, Si, Cu, Zn, Fe) within framework semi-discrete variational theory combined first-principles calculations. Depending on characteristics, modes governed by compositional-dependent...
Controlled incorporation of bioactive hydroxyapatite (HA) into poly(lactic acid) (PLA) signifies a promising approach to design and development biomedical-adaptive materials. Here we unravel microwave-assisted biomineralization synthesis HA nanowhiskers (HANWs), which were characterized by well-controlled diameter (∼30 nm) length (80 − 120 nm), combined with desirable calcium phosphorus ratio (Ca/P) 1.67. A high-shear liquid dispersion (HSLD) method that provided combination high pressure...
Different from the conventional planar fracture and simplified Newton model, for power-law slurries with a lower water-cement ratio commonly used in grouting engineering, flow model geological rough fractures is built based on ten standard profiles Barton (1977) this study. The numerical algorithm validated by experimental results. mechanism, grout superiority, water plugging of pseudo plastic slurry are revealed. representations hydraulic properties JRCs obtained. results show that...
The application of precast segmental bridge columns (PSBCs) is still restricted in seismicity areas due to concerns such as lower lateral stiffness and column base bearing capacity. To enhance the applicability PSBCs, this study proposed a novel approach confining them with grouted GFRP tubes. Four one reference specimens were tested under low cyclic loading evaluate effects energy dissipation (ED) bars ratios, concrete interlayer strength, type segment concrete, pouring methods within outer...
Abstract For the prediction of abnormal states in overall injection molding equipment, this paper proposes a novel idea GRU-based anomaly monitoring for thereby enriching research field. Firstly, existing multimodal data equipment is mined, and model trained using GRU as benchmark simulating states. Finally, practical examples are used verification. Experimental results show that method can effectively monitor equipment. Currently, there relatively few studies on The proposed enriches area...
Hybrid cascaded multi-terminal HVDC transmission technology is a research hotspot in the field of DC transmission. The system topology adopts line commutated converter (LCC) converters at sending end and high-end LCC receiving series with multiple low-end MMC converters. When modular multilevel (MMC) occur an AC side failure or blocking failure, surplus power will cause voltage overvoltage, which endanger safe stable operation system. This paper proposes master-slave control adaptive droop...

With the rapid advancements in digital signal processing and communication technology, utilization of detectors has become prevalent across numerous domains. Among these detectors, absolute value hold particular significance. This article primarily delves into delicate balance between latency energy consumption within realm 4-bit detectors. To commence, we provide an exhaustive exposition fundamental design operational principles underpinning Subsequently, embark on a comprehensive...
In order to quickly recover the transportation network after a disaster, this paper considers recovery scenario in which multiple repair teams perform work. Also, considering that there is an interval between tasks, travel time spent before reaching each task work non-negligible, so routing planning of required. To solve problem, proposes resilience-based and scheduling model for gives schedule team completion whole obtain solution results proposed complex uses Ant Colony System algorithm solving it.
We model post-disaster critical infrastructure network maintenance scheduling problem considering the uncertainty of resource requirements through Markov decision process. Then we design state space, action and reward function suitable for use a simulation experiment to verify rationality model. Finally, analyze influence size on repair delay caused by damage paths give corresponding suggestions. It expands application reinforcement learning in field has strong theoretical significance value.
