Addressing the global challenge of promoting digital transformation in rural areas and reducing urban–rural divide is crucial. This study explores digitization within framework tourism literature, an area that has received limited scholarly attention. Utilizing economic geography methodologies, this research examines multiscale relationship between development efficiency at county level. Our empirical findings reveal significant spatial heterogeneity both development, diverging from existing...
In this paper, we explore the optimal combination of femtosecond laser drilling parameters for micro-hole processing on DD6 single-crystal high-temperature alloy and analyze significance parameter variations microstructure characteristics holes. The L25(56) orthogonal test was performed by controlling six during ring processing: average power; overlap rate; defocus feed amount; gas pressure; end position. influence factors analyzed ANOVA, were optimized genetic algorithm. Scanning electron...
The requirements of using modern aircraft have been increased constantly, which results in different influencing factors R&D and procurement costs.And the original model predication for costs appears accretion estimation especially extensive advanced avionics composite materials, stealth materials.In this paper, we take predict as an example apply method hierarchical partial Least Squares regression modeling verification.Case analysis indicates that, proposed by paper is feasible error tiny.
Abstract In this paper, we explore the optimal combination of femtosecond laser drilling parameters for micro-hole processing on DD6 single-crystal high-temperature alloy and analyze significance parameter variations microstructure characteristics holes. The L 25 (5 6 ) orthogonal test was performed by controlling six during ring processing: Average power, Overlap rate, Defocus Feed amount, Gas pressure, End position. It is found that entrance micro-holes has good roundness, while a large...
Aiming at the problems of inaccurate and non-objective information in analysis takeoff landing performance for fixed-wing aircraft, a comprehensive evaluation method aircraft's based on improved analytic hierarchy process(AHP) gray theory is given. Firstly, weight calculation multi-matrix AHP proposed by increasing number judgment matrices, so that influence single expert's score results can be weakened, subjectivity coefficient vector reduced. Then, matrix calculated theory; finally, value...
