Study on Scale Formation in Leachate Transport Pipelines Based on System Dynamics(SD)
Luziping Zhang, Sanxing Chen, Wenbo Liu
This study investigates the scaling process in landfill leachate collection and transportation pipelines. A system dynamics model was established to predict pipeline scaling, employing a combined approach of orthogonal experiments， and simulation techniques to account for the nonlinear coupling effects of crystallisation kinetics and thermodynamics, among other factors. Different parameters were adjusted to study variations in scaling behaviour. The results show that the model predictions of sca...

A Heuristic Approach for Fixed-Route Vehicle Charging with Nonlinear Time-Dependent Charging Function
Yangshuai Ke, Rui Luo, Jun Yang
This paper investigates the Fixed-Route Vehicle Charging Problem based on Time (FRVCP-T), considering the nonlinear characteristics of electric vehicle (EV) charging functions. A new linearization method using secant lines is introduced to convert the nonlinear charging curve into a Mixed-Integer Linear Programming (MILP) model with significantly fewer variables. To solve large-scale instances efficiently, we propose a heuristic algorithm—Dynamic Iterative Partial Optimization with Tabu Search (...

Seasonal land-Sea Difference of Arctic Amplification Strength: Insights From Reanalysis Datasets
Miao Fang, Huan Chang
Quantitative and contrastive understanding of the seasonal land-sea difference in Arctic amplification (AA) strength is important but it still has not been well characterized. This research studied this issue using five reanalysis datasets and compared AA strength with exiting knowledges on AA variations. Results showed that the seasonal AA over Arctic land maintains a relatively stable magnitude (i.e., on the order of 2) and spatial coverage in different seasons; there is no AA effect in summer...

CSSWin-UNet: A Transformer UNet Combined with Patch-Based and Cross-Shaped Windows for Medical Image Segmentation
Fufang Li, Xinting Chen
In medical image segmentation, both Convolutional Neural Networks (CNNs) and self-attention mechanisms have shown success but also have limitations. CNNs excel at capturing local features but struggle with long-range dependencies, while self-attention effectively models global context but is computationally intensive and may lose fine local details. To address these challenges, we propose CSSWin-UNet, a novel U-shaped architecture that integrates two complementary self-attention mechanisms(Swin ...

Design of Satellite Assembly Resource Management System Based on Data Mining
Lei Feng, Huayuan Hu
With the continuous breakthroughs in China's aerospace technology, the number of research and development tasks for large and medium-sized spacecraft has shown an explosive growth trend. In contrast, the production resources for spacecraft assembly have failed to grow proportionally, leading to localized shortages of production resources. On the other hand, the lack of flexible, objective, and simple resource regulation means has resulted in relatively rigid and immobile allocation of production...

Strain and Lateral Deformation Monitoring of Reinforced Concrete Column using Distributed Fibre Optical Sensor
Jun Xia, Rengeng Zheng, Jinfeng Zhang
A reinforced concrete frame structure with a large-span curved beam was designed for a stadium. The finite element analyses show that the stiffness and thus the lateral deformation of the column are critical to the performance of the curved beam. Therefore, distributed fibre optical sensors (DFOS) were used to monitor the strain and lateral deformation. The sensors were installed on the reinforcing rebars close to the interior and exterior sides of the column, and the lateral deformation can be ...
