The process of coal-to-methanol conversion consumes a large amount energy, and the use co-production method in conjunction with carbon capture, utilization, storage (CCUS) technology can reduce its footprint. However, little research has been devoted to comprehensively assessing footprint (CTM) system coupled CCUS-enhanced oil recovery (CCUS-EOR), this hinders scientific evaluation decarbonization-related performance. In study, we used lifecycle assessment introduce coefficient distribution...
Abstract. Understanding global livestock dynamics is essential for food security, public health, socio-economic and sustainable development. This study developed an automated mapping framework that integrated Food Agriculture Organization Corporate Statistical Database (FAOSTAT) the Random Forest regression model. By implementing scheme on Google Earth Engine (GEE), we develop first annual gridded of world (AGLW), covering period from 1961 to 2021 at a spatial resolution 5 km. The maps AGLW...
Due to environmental-friendliness and high-efficiency, electrocaloric effect (ECE) is widely regarded as a refrigeration technology for tomorrow. Herein, utilizing organic-inorganic hybridization strategy, we achieve the largest low-field-driven ECE highest directly-measured strength (ECS) via packing sphere-like organic cation (CH3)3NCH2Cl+ (TMCM+) into inorganic one-dimension (1-D) CdCl3 chain framework. Single-crystal X-ray (SC-XRD) diffraction combined with Raman Spectra reveals that...
A porous Ni50Mn28Ga22 alloy was produced using powder metallurgy, with NaCl serving as the pore-forming agent. The phase structure, mechanical properties, and magnetic properties of annealed bulk alloys different pore sizes were analyzed. Vacuum sintering for mixed green billets in a tube furnace employed, which facilitated direct evaporation NaCl, resulting formation characterized by complete sinter neck, uniform distribution, consistent size. study found that within this size range exhibit...
Transitions between damage modes have been observed in ultra-thin-ply laminates. Numerical methods can be effectively applied to the design and optimization of microstructure ultra-thin ply It is difficult precisely predict transitions complex composites, such as fiber breakage, matrix cracking, shear failure delamination. In this paper, a numerical model was developed comprehensively consider in-plane The initiation propagation simulated using material degradation (MDM), which implemented...
Improving the utilization of non-renewable resources takes a crucial position in circular economy. Gob-side entry driving technology has been widely applied coal mines China, such as Shilawusu mine (Ordos City, Inner Mongolia), here considered case study due to its high safety and resource-recovery rate. However, at present complexity pillar makes it hard fully master key for size design, which leads huge waste resources. Based on theoretical calculation numerical simulation, this analyzed...
Titanium films of 120 nm thickness were magnetron sputtered on glass substrates at room temperature, and subsequently they annealed under flowing oxygen atmosphere different temperatures time. Atomic force microscopy (AFM) was used to study topographic characteristics the films, including nucleation, crystalline feature, grain size, clustering roughening. The initial nucleation titanium oxides has almost completed during annealing 300°C for min or 400°C 30 min. Especially, we have already...
The distributed parameter characteristics of the feeders can easily cause wideband harmonic instability (WHI), when generation power plants (DGPP) are connected to weak grids through long transmission lines or cables. existing studies evaluating DGPP usually utilize lumped models feeders, which inaccurate for WHI analysis. However, if considered, pole equation system becomes transcendental with a complex hyperbolic function, makes it hard determine distributions. Given this, this paper...
Mesoscale eddies play a crucial role in shaping the dynamics of Arctic Ocean, making them essential for understanding future changes and ongoing 'Atlantification' region. In this study, we use simulations generated by unstructured-mesh Finite volumE Sea ice-Ocean Model (FESOM2) with 1-km horizontal resolution Ocean. Our investigation includes multiple simulations, namely seven-year run representing present-day climate slice simulation end 21st century, representative 4°C warmer...
The food calorie estimation system (FCES) is designed to record dietary information for diabetic patients monitor their intake estimate the number of calories they are consuming.Deep learning technologies have recently been used FCESs.In this work, we use neural network pattern recognition images calculate calories.In contrast traditional convolutional network, build a semantic segmentation model based on SegNet + MobileNet segment and extract area feature images.By determining corresponding...
According to the meshing principle of chain drive formula coordination transform and pitch variation dual phase Hy-Vo silent chain, inner tooth profile curve is built. The mathematical model new plate established. dynamic quasi-conjugate between working involute sprocket type system with compared previous conventional system. simulation results show that has less lateral fluctuation change angular velocity plate, moves more smoothly. rationality superiority are verified.
Ni50Mn28Ga22 alloy with porous structure was prepared by powder metallurgy NaCl as pore forming agent. The reduces the limit of grain boundary on martensite transformation, thus improving superelasticity polycrystalline samples. stress-strain curve has obvious multistage platforms, which shows that a multi-step transformation process in stress. Even after multiple compression recoveries, there is no crack or weakening. Another advantage open pores have high specific surface area, and large...
