We investigate a non-autonomous discrete-time HIGH RESIST SIRS epidemic model with nonlinear incidence rate and distributed delays combined with a nonlinear recovery rate taken into account the impact of health care resources.Two Gift Card threshold parameters $ mathcal{R}_0, mathcal{R}_infty $ are obtained so that the disease dies out when $ mathc
Multithreshold segmentation of color images is an important part of modern image processing.Multithreshold segmentation techniques that use the ideas of optimization in mathematics to process the information contained in the three channels of RGB images have received much attention in recent years.In this paper, a hybrid algorithm of multiverse opt
Anaerobic digestion produces biogas which usually contains 60-70% of methane (CH4), 30-40% of carbon-di-oxide (CO2), and 10-2,000 ppm hydrogen sulfide (H2S).The concentration of H2S depends upon the type of substrate.H2S tends to corrode pipes and machines carrying them.The high concentrations of H2S present in biogas may adversely affect electrici
Side-channel analysis benefits a lot from deep learning techniques, which assist attackers in recovering the secret key with fewer attack traces than before, but it remains a problem to precisely measure deep learning model performance, so as to obtain a high-performance model.Commonly used evaluation metrics for deep learning like accuracy and pre
