High elevation areas are sensitive and vulnerable to climate change and exhibited relatively rapid changes in response to warming Covers involving changes of floristic composition, species upward migration, shrub and tree encroachment and surface area changes.For this reason, it is important to provide quantitative studies as tools allowing a long-
Concrete canvas reinforced with spacer fabric has increasingly gained popularity due to its lightweight, great flexibility, high strength and low contamination compared to ordinary concrete.In order to fully explore the structure and performance of this novel composite, this review illustrates how to design high-performance concrete canvas and pres
Flammulina filiformis, as one of the most popular edible fungi in East Asia, is produced in an industrialized and standardized way.However, its monotonous variety and product convergence have seriously restricted the development of the industry.In this study, 11 cultivated strains and 13 wild strains of F.filiformis were collected from multiple reg
Aiming at the shortcomings of traditional radar identification based on artificial judgment and module matching, this paper proposes an intelligent identification algorithm based on joint time-frequency.The radar radiation source signal is transformed by time-frequency, and the processed signal is input into the automatic encoder through different
This paper proposes a new method to strengthen the nonlinear kinetic complexity and ergodicity of Lorenz system.Through the analysis of auto-correlation, frequency distribution, approximate entropy and information entropy, the improved Lorenz system has better dynamical properties than Lorenz system.According to NIST-800-22 test results, the chaoti
