Personal credit scoring is a challenging issue. In recent years, research has shown that machine learning satisfactory performance in scoring. Because of the advantages feature combination and selection, decision trees can match data which have high dimension complex correlation. Decision tend to overfitting yet. eXtreme Gradient Boosting an advanced gradient enhanced tree overcomes its shortcomings by integrating models. The structure model determined hyperparameters, aimed at...
For large-span bridge monitoring, displacement measurement is essential. However, it remains challenging to accurately estimate displacement. When calculated by the double integration of acceleration, a low-frequency drift appears in estimated Displacement can also be from strains based on Euler–Bernoulli beam theory. prior knowledge mode shapes and neutral axis location target are required for strain–displacement transformation. In this study, we propose finite impulse response filter-based...
Carbon is an important energy carrier. It abundant in the world, existing richly coal and biomass. Its released mainly through oxidation. A heat of ∼393 kJ may be obtained from complete oxidation 1 mol carbon. The most conventional method carbon combustion, which has problems pollutant emission low efficiency. However, electrochemical oxidation, chemical can converted into electricity with high efficiency pollution. Herein, we give a brief review our work on novel technology generating...
In view of the fact that traditional air target threat assessment methods are difficult to reflect combat characteristics uncertain, dynamic and hybrid formation, an algorithm is proposed solve multi-target problems. The attribute weight calculated by intuitionistic fuzzy entropy (IFE) time series gained Poisson distribution method based on multi-times data. Finally, sequencing model IFE VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) established with example which indicates...
Direct carbon solid oxide fuel cell (DC-SOFC) is a promising technology for electricity generation from biomass with high conversion efficiency and low pollution. Biochar derived wheat straw utilized as the of DC-SOFC, cermet silver gadolinium-doped ceria material both cathode anode yttrium stabilized zirconia electrolyte. The output performance DC-SOFC operated on pure 197 mW cm−2 at 800°C increases to 258 when 5% Ca, catalyst Boudouard reaction, loaded char. Higher power utilization are...
Metal additive manufacturing (AM) enables rapid customization of complex parts. However, it leads to forming columnar grain structures which give the AM parts anisotropic properties. In this study, we propose a pulsed laser-assisted (PLAAM) technique for in-situ refinement Ti-6Al-4V A nanosecond laser was focused onto melt pool generate favorable environment promotion fine equiaxed grains. The PLAAM provided an average prior-β size 549.6 μm, compared that 1297 μm by conventional technique....
This study provides a physical insight into binding conditions (BCs) for nonlinear ultrasonic generation considering both propagating waves and stationary vibrations. First, the BCs are theoretically formulated Then, experimentally validated with special focus on modulation. Finally, advantages disadvantages using or vibrations discussed.
Damage often causes a structural system to exhibit severe nonlinear behaviors, and the resulting features are much more sensitive damage than their linear counterparts. This study develops laser wave modulation spectroscopy (LNWMS) so that certain types of can be detected without any sensor placement. The proposed LNWMS utilizes pulse generate ultrasonic waves vibrometer for measurement. Under broadband excitation laser, source generates modulations at various frequency values due...
