In this study, we propose a multi-agent glowworm swarm optimization (MAGSO) algorithm for the economic load dispatch (ELD) problem of large-scale hydropower station. The MAGSO integrates idea evolution (GSO) and interindividual cooperation system (MAS). structure, each GSO is treated as an agent cooperating in MAS before entering evolutionary process. proposed mechanisms enable to escape from local extremum, capture optimal solution expand diversity space. test results four benchmark...
Displacement is an important physical quantity of hydraulic structures deformation monitoring, and its prediction accuracy the premise ensuring safe operation. Most existing metaheuristic methods have three problems: (1) falling into local minimum easily, (2) slowing convergence, (3) initial value’s sensitivity. Resolving these problems improving necessitate application genetic algorithm‐based backpropagation (GA‐BP) neural network multiple population algorithm (MPGA). A hybrid (MPGA‐BP) put...
As the urban underground space environment gets more complex, cases of shield machines encountering and cutting through piles are becoming common. The interaction between cutter head pile foundation directly affects tunneling performance machine safety existing structure. To study machine, a calculation model force is established. A field test two was conducted rationality verified by comparing results with data. applied in project bridge Harbin Metro Line 3, China. operation parameters...
The hydraulic thrust system of the shield machine is used for driving forward and pose adjustment. It great significance to figure out mechanism motion characteristics ensure safety tunnel excavation. This study aims develop a model explore influence cylinder advancement on motions machine. Firstly, carried analysis established method describe position attitude during tunneling process by homogeneous transformation matrix. Then, new inverse kinematic was proposed quantify relationship...
This study proposes a two‐stage glowworm swarm optimisation (GSO) algorithm for the economical operation of inner plant hydropower station. Binary GSO and real‐coded (RCGSO) algorithms are applied with different types encodings to solve unit commitment sub‐problem economic load distribution (ELD) sub‐problem, respectively. Moreover, an improved dynamic patching mechanism is developed avoid invalid calculations enrich diversity solutions. A luciferin transfer helps escape local optimum...
Fosters accountability and desistance, not all relationships are beneficial. Some network members, particularly those linked to prior criminal behaviors, may perpetuate recidivism. Offenders often actively distance themselves from harmful influences while valuing prosocial connections. This study emphasizes the importance of evaluating both positive negative dynamics highlights need for targeted interventions that enhance constructive ties. These findings provide valuable insights...
Shield construction will cause the fluidization of soft soil which is characterized by flow plasticity. This paper presents two theoretical models behavior based on a fluid mechanics framework to understand during shield tunneling, especially under shearing action skin and cutting wheel. The characteristics field are discussed, their relationships with parameters such as advancing speed, wheel rotation, applied thrust torque, water content analyzed, while proposed theory verified results...
In the present study on rail corrugation, a field investigation is carried out typical section of Steel-spring Floating Slab Track (SFST) in Beijing subway for studying two distinct types corruga-tions generated by left and right rails curved sections metro line. Further, also done vibration response track components when trains pass over corrugations at SFST curve having small radius curvature (R=300m). The establishes an corrugation analysis model effectively combining SIMPACK ABAQUS....
As subsea shield tunnels are becoming increasingly popular, especially in coastal or river cities, the complicated construction environment poses multiple challenges that need to be addressed ensure their safety and reliable operation. This study presents results of centrifuge model tests aimed examine impacts navigable channel excavation seawall on deformation forces acting a tunnel. The symmetry tunnel structure, as well loading unloading effects from this engineering project, allow for...
