Ωζ-foliated Fitting Classes [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
All groups under consideration are assumed to be finite. For a nonempty subclass of Ω of the class of all simple groups I and the partition ζ = {ζi | i ∈ I}, where ζi is a nonempty subclass of the class I, I = ∪i∈I ζi and ζi ∩ ζj = ø for all i ≠ j, ΩζR ...

Experimental study on track irregularity of straddle-type monorail [PDF]

Scientific Reports
As straddle-type monorail systems evolve toward higher operational speeds, steeper gradients, and more diverse structural configurations, the design of guideway beams has become increasingly complex.

Technical note: A sigmoidal soil water retention curve without asymptote that is robust when dry-range data are unreliable [PDF]

Hydrology and Earth System Sciences, 2022
In a recently introduced parameterization for the soil water retention curve (SWRC) with a sigmoid wet branch and a logarithmic dry branch, the matric potential at the junction point of the sigmoid and the logarithmic branch (hj) was a fitting parameter,

Parameter optimization of a pure electric sweeper dust port by a backpropagation neural network combined with a whale algorithm [PDF]

Mechanical Sciences, 2023
Optimizing the structure of the suction port is the key to effectively improving the performance of the sweeping vehicle. The CFD (computational fluid dynamics) method and gas–solid two-phase flow model are used to analyse the influence rule of the ...

External Multi-Scale Voting Network for Semantic Segmentation Model [PDF]

Jisuanji gongcheng, 2022
To address the high training complexity of multi-scale shared networks in semantic segmentation and the unsatisfactory fitting effect of multi-scale attention maps for small targets, long targets, and target edges, a new external multi-scale voting ...

Recommendations for spectral fitting of SO₂ from miniature multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements [PDF]

Atmospheric Measurement Techniques, 2020
Fitting sulfur dioxide (SO2) differential slant column densities (dSCDs) from multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements of scattered sunlight is challenging because actinic light intensity is low in the wavelength ...

Contribution to experimental investigation of fitting the current transformers' calibration curves [PDF]

Journal on Processing and Energy in Agriculture, 2020
The paper experimentally investigates the problem of fitting calibration curves of current transformers (CTs). An efficient fitting algorithm enables precise and accurate electronic real-time correction of CT errors and thus effective improvement of ...

Time-domain proton-detected local-field NMR for molecular structure determination in complex lipid membranes [PDF]

Magnetic Resonance, 2023
Proton-detected local-field (PDLF) NMR spectroscopy, using magic-angle spinning and dipolar recoupling, is presently the most powerful experimental technique for obtaining atomistic structural information from small molecules undergoing anisotropic ...

Reducing errors on estimates of the carbon uptake period based on time series of atmospheric CO₂ [PDF]

Atmospheric Measurement Techniques, 2023
High-quality, long-time-series measurements of atmospheric greenhouse gases show interannual variability in the measured seasonal cycles. These changes can be analyzed to better understand the carbon cycle and the impact of climate drivers.
