Abstract. Atmospheric brown carbon (BrC) is a collective term for light absorbing organic compounds in the atmosphere. While identification of BrC and its formation mechanisms currently central effort community, little known about atmospheric removal processes aerosol BrC. As result, we report on series laboratory studies photochemical processing aqueous phase, by direct photolysis OH oxidation. Solutions ammonium sulfate mixed with glyoxal (GLYAS) or methylglyoxal (MGAS) are used as...
When Inconel 718 alloy is fabricated by selective laser melting and treated traditional homogenization plus double aging heat treatment (HA), its strength improves greatly, but ductility decreases. A novel (NHT) including higher temperature at 1150 °C for 2 h one-time lower 700 12 developed, which can overcome the strength-plasticity trade-off of alloy. The results show that recrystallized grains with annealing twins ultrafine strengthening phases form in specimen subjected to NHT. These...
A failure criterion fully considering the anisotropy and hydration of shale is essential for formation stability evaluation. Thus, a novel developed by using Jaeger's shear to describe strength reduction caused clay minerals evaluate hydration. This defined with four parameters in (S1, S2, α φ), three (k, ωsh σs) two material size (d l0). The physical meanings determining procedures these are described. accuracy applicability this examined published experimental data, showing cohesive...
A novel single-inductor dual-input dual-output dc-dc converter with pulse width modulation control is proposed for a solar energy harvesting system. The first input of the from photovoltaic (PV) cells and second rechargeable battery. Apart conventional role providing regulated output voltage to power loading circuits, also clamps PV cells' maximum point value maximize efficiency. When harvest more than load, surplus used charge cannot sufficient power, schedules battery load together. test...
In this study, the potential application of compressive sensing (CS) principle in image fusion for infrared (IR) and visible images is studied. First, theory CS introduced briefly. Some comparative analyses different reconstruction techniques are carried out view their performance multisensor recovery minimum number sampling measurements one has to take achieve perfectly investigated afterwards. Then, a novel self-adaptive weighted average scheme based on standard deviation merge IR...
Isothermal compression tests at temperatures ranging from 523 to 723 K and strain rates 0·01 10 s −1 were performed on AZ31 magnesium alloy reveal the deformation characteristics. The flow stress–strain curves show that stress reaches a peak value then decreases steady values, which characterise dynamic softening. measured was modified by friction temperature correction, reflect corrected stresses are lower than ones effect of rise is obvious high rate (≥1 ). employed develop constitutive...
Rare earth metals have strong affinity with O and S in molten steel. However, due to high density of rare inclusions close that steel, are not easy float up it is conducive take away S. In this paper, the influence magnesium alloy on evolution mechanism deoxidization desulfurization H13 steel was analyzed, thermodynamic calculation developed. The research results indicate composite low-density MgO attaching or wrapping surface high-density Ce formed after adding Ce–Mg Compared alone, lower...
In this research, metakaolin-based geopolymers were synthesized to study their deterioration in marine environment. The exposed air, seawater, dry-wet and heat-cool cycles of seawater for 30, 60 90 days. mechanical property the was characterized through compressive strength measurements, microstructures measured by X-ray diffraction (XRD), scanning electron microscope (SEM) nuclear magnetic resonance (NMR) apparatus. It found that environment inhibited geopolymerization reactions, so a low...
Continuous integration (CI), a crucial technology for accelerating software delivery, employs prioritization methods to optimize testing efficiency. Reinforcement-learning-based techniques of test cases can dynamically adjust the strategy based on feedback. However, existing reinforcement learning models either use feature information from individual or complete all as input. The model’s input is fixed and does not vary characteristics case set. This leads inability handle various ranking...
