According to the relevant test standards and characteristics of special electric vehicles, first-level evaluation indexes are set up as power, trafficability, mass geometric parameters drive parameters, second-level determined based on typical driving conditions. The usability trafficability index is analyzed, weights primary secondary by AHP CRITIC respectively, comprehensive combination qualitative analysis quantitative analysis. correlation degree vehicle calculated grey theory, result...
We show that while the statistics of static speckle patterns are generic, fluctuations in change within greatly enhanced localization transition. The probability distributions displacement phase singularities and standard deviations changes intensity with frequency shift incident microwave radiation given terms same expression which describes distribution total transmission. This function depends only upon a single parameter, variance corresponding variable. changing transition reflects...
Monitoring sensors in complex engineering environments often record abnormal data, leading to significant positioning errors. To reduce the influence of arrival times, we introduce an innovative, outlier-robust localization method that integrates kernel density estimation (KDE) with damping linear correction enhance precision microseismic/acoustic emission (MS/AE) source positioning. Our approach systematically addresses times through a three-step process: initial location by 4-arrival...
The statistics of the field structure in vortex core surrounding phase singularities random wave fields are measured and calculated for diffusive localized waves. Excellent agreement is found between experiment theory. variation with geometric angle deterministic, depending only upon eccentricity elliptical intensity contours, epsilon, whose probability distribution shown to be universal. vorticity reflect both distributions within a Gaussian given value total transmission mesoscopic transmission.
The optical atomic clocks have the potential to transform global timekeeping, relying on state-of-the-art accuracy and stability, greatly improve measurement precision for a wide range of scientific technological applications. Herein we report development clock based 171 Yb atoms confined in an lattice. A minimum width 1.92-Hz Rabi spectra has been obtained with new 578-nm interrogation laser. in-loop fractional instability reaches 9.1 × 10 −18 after averaging over time 2.0 4 s. By...
We report a crossover in optical propagation random layered media from localization towards diffusion as the interaction of wave with sample is transformed one to three dimensional due nonuniformity layer thickness. The occurs at point that lateral spread equals transverse coherence length transmitted speckle pattern.
The dense granular flow spallation target is a new concept proposed for an Accelerator-Driven Sub-critical (ADS) system. In this paper, the beam-target configurations of tungsten ADS with thermal power 1 GW explored. beam profile options using different scanning methods are discussed. critical geometry parameters adjusted to investigate performance from aspects neutron efficiency, stability and temperature distribution in medium. To figure out how under accident conditions would behave,...
We find a transformation in the probability density of intensity for light transmitted through stacks glass slides increasing thickness from one-dimensional (1D) to quasi-1D statistics. argue that this represent crossover universal first order statistics beyond 1D associated with appearance phase singularities at nulls speckle pattern.
Three types of novel DGSs are proposed firstly in this paper. The electric and magnetic coupling structures for three DGS studied respectively. S-parameters show that different can cause frequency responses, especially the stopband characteristics position transmission poles. At same time, similar have responses DGSs. In order to explore usefulness coupled-DGSs, two kinds low-pass filters (LPFs) designed. Both using coupled-DGSs compact dimensions, wide passbands excellent attenuation stopband.
