The model incorporates Caputo fractional derivatives, accounting for memory and hereditary properties, to provide a more realistic depiction of disease progression. The system of equations models transitions between compartments based on genetic transmission, recovery, and demographic factors. To solve the model, the Laplace Residual Power Series (LRPS) method is employed, offering a semi-analytical approximation of the system’s behavior over time. Power series expansions for each compartment provide insights into the temporal dynamics of the model under fractional-order influence. A comparison between the standard Residual Power Series (RPS) and LRPS methods is conducted to evaluate their accuracy and efficiency. Results demonstrate that the LRPS method outperforms the RPS method in terms of convergence and solution accuracy. Specifically, the LRPS method exhibits faster convergence to the true solution with a significantly lower absolute error, making it more reliable for solving fractional-order models. The absolute error between the LRPS and exact solutions decreases more rapidly, showcasing superior accuracy, particularly at higher fractional orders. Convergence analysis reveals that the LRPS method converges more quickly than the RPS method, especially as the fractional-order parameter increases. The study highlights the importance of incorporating fractional calculus in modeling hereditary diseases, providing valuable insights into disease dynamics. By identifying critical thresholds and sensitive parameters, the model can inform effective control strategies and improve our understanding of disease spread, offering more accurate predictions for future interventions.

Thermal conductivities of whole giant reed and crushed common reeds panels samples, within minimal processing, were measured to be used in the design of insulating cladding according to Egyptian Code for Energy Efficiency in Residential Buildings. Then, digital simulation was conducted on a validated non-insulated case-study residential villa, to asses changes in energy performance after retrofitting with reed cladding panels.

Simulation results indicated that retrofitted models employing giant reeds claddings and common reed claddings achieved better energy savings; 4.73 % and 4.27 %, respectively; compared to model employing expanded polystyrene and gypsum board wall cladding (4.50 %).

This study aims to design an off-grid hybrid energy system to meet the energy needs of 300 households in Turkey and to evaluate its technical and economic performance across varying renewable penetration levels. System design, simulation, and techno-economic analysis were conducted using HOMER Pro, with four configurations corresponding to 25 %, 50 %, 75 %, and 100 % penetration levels. Li-Ion and Lead-Acid batteries were employed separately to compare performance, and three scenarios differing in load demand and inter-community distances were modeled using Python and PYPSA. Optimal configurations were determined using Ant Colony Optimization (ACO), Whale Optimization (WO), and Flying Foxes Optimization (FFO). Results indicate that the lowest net present cost (NPC) system corresponds to 100 % penetration with Li-Ion batteries, comprising 28 wind turbines, 364 kW photovoltaic arrays, a 233 kW generator, a 387 kW inverter, and 1000 batteries, with a NPC of 1.79 million $. Li-Ion batteries demonstrated superior economic performance compared to Lead-Acid batteries, and systems with 75 % and 100 % penetration were the most cost-effective.

Currently, two methods, namely the direct and indirect methods, are employed to determine the UCS. The direct method, however, is high-priced and time-consuming. Consequently, the development of a stable and efficient indirect method holds great significance. In this study, kernel extreme learning machine (KELM) and support vector regression (SVR) are utilized to construct prediction models. Additionally, five metaheuristic optimization algorithms are introduced to strengthen the performance of the prediction models. Ten ensemble models are developed to predict the UCS. Using six input variables, an optimal prediction model is established based on four performance indicators. To address the stochasticity of model outputs, each model is run 100 times to obtain 100 output results. Furthermore, score analysis, uncertainty analysis and Wilcoxon test are employed to evaluate the superiority or inferiority of prediction models more precisely, respectively.
