Logistic-Grey-Markov prediction model

Grey Systems Theory and Application, Год журнала: 2025, Номер unknown

Опубликована: Фев. 19, 2025

Purpose In this study, a novel grey combined model, termed the logistic-Grey-Markov is proposed. This model aims to construct relation function between transition probabilities and residual errors fully utilize information from calculate optimal for more accurate predictions. Design/methodology/approach To address issue, logistic introduced improved accommodate different types of samples. Then applied sample errors. Additionally, obtain coefficients in function, least square objective constructed, Levenberg–Marquardt algorithm employed. With these coefficients, can probabilities. Findings The ensures that utilized case studies demonstrate proposed effectively improve prediction accuracy. Originality/value One strengths Grey-Markov its ability predict outcomes with small highly volatile However, accuracy not ideal due waste errors, especially when only size available. model.

Alternative Energy Will Greatly Reduce the Impact of Aircraft Activities on Public Health in China

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Май 7, 2025

The increasing PM2.5 emissions from aviation in China significantly impact human health, necessitating the urgent adoption of clean energy solutions. This study assesses aviation-related on deaths 2024 to 2050. concentration data 2015 2022 are used as a baseline, and three healthcare development scenarios considered. then compares changes concentrations under different mitigation pathways, including Sustainable Aviation Fuel (SAF), Hydrogen Turbine Engine (HTE), Cell (HFC) engine. It incorporates these into Global Exposure Mortality Model (GEMM) estimate excess attributable activities China. scenario with significant medical improvements results 4365 by 2050, only 15.37% Business Usual (BAU), 32.91% congestion due severe aging. Using China's sector can reduce number caused aviation, varying degrees improvement depending start time type used. Further analysis reveals that all scenarios, proportion male is higher than females, at 58.10, 61.20, 59.23%. Deaths ischemic heart disease (IHD) constitute highest proportion, approximately 49.43%.
