The technology of microbially induced carbonate precipitation (MICP) provides a promising approach improving the durability and safety concrete structures. CaCl2, common calcium source MICP, may be detrimental for steel bars significantly affects reinforced concrete. Therefore, alternative sources their feasibility are investigated in paper. uniaxial compressive strength tests water absorption ratio carried out biogrouted sand columns treated with different sources, mineralogical...
The click-through rate (CTR) forecast is among the mainstream research directions in domain of recommender systems, especially online advertising suggestions. Among them, multilayer perceptron (MLP) has been extensively utilized as cornerstone deep CTR prediction models. However, current neural network-based models commonly employ a single MLP network to capture nonlinear interactions between high-order features, while disregarding interaction differentiated resulting poor model performance....
The time-integrated spatial coherence of neonlike germanium x-ray laser radiation has been studied with a new dispersing diagnostic. Angle-dependent data are recorded by sampling the diverging beam at each lasing wavelength in several directions simultaneously. Measurements coherence, and hence effective source sizes, relevant to output beams from double-slab targets for J=2–1 spectral lines wavelengths 28.6, 23.6, 23.2 nm J=0–1 line 19.6 show differences, which indicate different conditions...
The spatial coherence of a nanosecond pulsed germanium collisionally excited x-ray laser is measured experimentally for three target configurations. diagnostic based on Young's slit interference fringes with dispersing element to resolve the 23.2- and 23.6-nm spectral lines. Target configurations include double-slab target, known as injector, geometries in which injector image relayed seed either an additional single-slab or second target. A special feature this study observation change...
X-ray computed tomography (x-ray CT) was applied to visualise the local deformation patterns caused by miniature cone penetration tests (CPTs) in a calibration chamber filled with fine grained quartzic sand and pressurized vacuum. A reference test conducted during which scanned at several stages of penetration. The measured attenuations were translated into density maps resolution 0.25 x 1mm using established scanning layered samples different densities. Test results showed that dilating...
The time dependence of the spatial coherence combined spectral lines at 23.2 and 23.6 nm from Ge xxiii collisionally pumped soft-x-ray laser with a double-slab target is examined within single nanosecond pulse by use Young's interference fringes streak camera. High source intensity linked low vice versa. Calculations intensity, size, position have also been made; these calculations refer to single-slab source. Comparison between observed calculated intensities, sizes both derived...
