The Utah Fly's Eye detector has revealed a change in the cosmic ray composition which is correlated with structure all-particle energy spectrum. data can be fitted by simple model of steep power law spectrum heavy nuclei overtaken at high energies flatter protons. transition occurs near ${10}^{18.5}$ eV. Anisotropy not detected, so high-rigidity particles above do originate disk Galaxy. An outstanding event 3\ifmmode\times\else\texttimes\fi{}${10}^{20}$ eV implies that highest contemporary...

Traffic accidents occur frequently, causing significant losses to people’s lives and property safety. Accurately predicting the severity level of traffic is great significance. Based on accident data, this study comprehensively considers various influencing factors such as geographical location, road conditions, environment. The data are divided into accident-related categories, weather-related road- environment-related categories. machine learning method improved through integration for...
We study the spectrum and average mass composition of cosmic rays with primary energies between 10^{17} eV 10^{18} using a hybrid detector consisting High Resolution Fly's Eye (HiRes) prototype MIA muon array. Measurements have been made change in depth shower maximum as function energy. A complete Monte Carlo simulation response comparisons simulations leads to conclusion that ray intensity is changing f rom heavier lighter this energy range. The consistent earlier measurements supports...
The average mass composition of cosmic rays with primary energies between ${10}^{17}$ and ${10}^{18}\mathrm{eV}$ has been studied using a hybrid detector consisting the High Resolution Fly's Eye (HiRes) prototype MIA muon array. Measurements have made change in depth shower maximum density as function energy. results show that is changing from heavy to lighter mix energy increases.
We use the depth of maximum distribution as measured by stereo Fly's Eye detector to study chemical composition primary cosmic radiation between 3 \ifmmode\times\else\texttimes\fi{} ${10}^{17}$ eV and ${10}^{19}$ eV. The analysis depends on simulations response well sensitivity assumptions about properties hadronic interactions that determine cascade development. find incident particles include both heavy nuclei protons in comparable amounts. fraction appears increase at highest energy explored.
The cosmic-ray composition around 1018 eV is reexamined using the Chou-Yang model for simulation of air showers and comparing with Fly's Eye data. This quite different from models previously used. Using this leads to same conclusion that primary gets lighter in region 3 × 1017 1019 eV. a changing not sensitive choice because it results measured elongation rate being greater than predicted constant by any reasonable can account depths shower maxima at threshold energy. That constraint on also...
Aiming at the problem that multi-layer non-negative matrix decomposition can not make full use of spatial and spectral features hyperspectral images, an improved unmixing algorithm is proposed in this paper. First, kmeans++ clustering employed to cluster pixels image, constructing weight. Additionally, sparse representation method used sparsely encode high-dimensional data based on geometric structure resulting weight characterizes intrinsic image. These two matrices are then fused construct...

PZ summation is a key technology in broadband seismic exploration technology, which can effective suppress of ghost waves, and widely used OBC acquisition. The mathematical model was first proposed based on the geophone recording velocity field. With advancement instrument, MEMS accelerometer applied dual-sensor acquisition, but low frequency acceleration field signal recorded application weaken.
