An Improved Whale Optimization Algorithm for the Integrated Scheduling of Automated Guided Vehicles and Yard Cranes
1. Introduction The automated container terminal (ACT) is a key hub in the global supply chain network. With the rapid development of global economic trade and the increase in the size of ships, the volume of shipping orders has soared. This surge poses significant challenges to the transfer capacity and service levels of container terminals. The number of mega-ships and containers worldwide is expected to continue to grow in the future.
An Adaptive Large Neighborhood Search for a Green Vehicle Routing Problem with Depot Sharing
1. Introduction In the past decade, global warming has been a hot topic and has aroused more and more concern. Several recent studies [1] have demonstrated the seriousness of global warming. One of the main causes of global warming is the large amount of greenhouse gases produced by human activities, of which carbon dioxide is the main component. The global transport network generates a significant amount of carbon emissions, with road transport responsible for approximately 75% of this total [2].
DIPEA-induced Si-H Activation of Siloxane for Hydrosilylation Polymerization via Metal-Free Photocatalysis
DIPEA-induced Si-H Activation of Siloxane for Hydrosilylation Polymerization via Metal-Free Photocatalysis Although metal-free hydrosilylation of siloxanes is essential for the industrial preparation of organosilicon compounds due to its unique advantages, such as the avoidance of the use and residue of precious metals, efficient metal-free silicon hydrogenation reactions are still rare.
Characteristics of Sudden Change in Aerodynamic Load of High-Speed Train Caused by Wind Barrier and Its Buffer Measure
1. Introduction The modern railway infrastructure is continuously being improved, leading to a gradual increase in the construction of high-speed railway lines in regions prone to strong winds. However, when a high-speed train (HST) runs in crosswind environments, its aerodynamic performance deteriorates, potentially jeopardizing the safety of train operations.

Path Planning Algorithm for Dual-Arm Robot Based on Depth Deterministic Gradient Strategy Algorithm
1. Introduction In the era of Industry 4.0, one key aspect of achieving smart factories is reducing reliance on human labor through collaborative automation using robot manipulators [1]. This reduction in reliance has become particularly evident in various tasks, including factory assembly lines, space exploration, customer service, as well as exploration and rescue missions. Consequently, enhancing the operational efficiency of multi-arm manipulators has become of utmost importance.
Janus Layers and Electronic Structure of 1T-(TiSeS)2
Janus Layers and Electronic Structure of 1T-(TiSeS)2 The TiS2-TiSe2 is one of the most studied titanium based solid solution system. However, so far, all research on it has only focused on its disordered phase. Here, we systematically investigate its ordered phases. Using a structure search method based on particle swarm optimization (CALYPSO) algorithm, we identify TiSeS-156 and discover a new structure (1T-(TiSeS)2).
Knowledge Graph Construction Based on a Joint Model for Equipment Maintenance
1. Introduction The explosive growth of equipment maintenance data has not only changed the norm for the research and analysis of maintenance but has also brought new opportunities and challenges to the way in which maintenance is carried out [1]. In the field of equipment maintenance, these two requirements place considerable workload and stress on the maintenance engineer.
The Lightweight Anchor Dynamic Assignment Algorithm for Object Detection
4.2.2. Training and Inference Details The experimental environment is a setup with an Intel Core i9-10900K [email protected] GHz, NVIDIA GeForce RTX 3090, 64 GB of RAM, and the operating system is Ubuntu 18.04. The model uses ResNet-50 [31] pre-trained by ImageNet [32] and a five-layer feature pyramid structure as the backbone network, both with a training period of 1×. According to the linear strategy, the batch size of training was adjusted to eight for 180 k iterations (i.e., 12 epochs).

Digital-Twin-Driven AGV Scheduling and Routing in Automated Container Terminals
Abstract : Automated guided vehicle (AGV) scheduling and routing are critical factors affecting the operation efficiency and transportation cost of the automated container terminal (ACT). Searching for the optimal AGV scheduling and routing plan are effective and efficient ways to improve its efficiency and reduce its cost. However, uncertainties in the physical environment of ACT can make it challenging to determine the optimal scheduling and routing plan.

Geographic Variation of Plant Circadian Clock Function in Natural and Agricultural Settings
Plants exhibit a remarkable capacity to adapt to changing environments. Their immobility creates a natural selective pressure to acquire a repertoire of finely tuned responses that modify their physiology in response to the environmental conditions. The challenge is exceedingly high for a plant; they need to respond to a multitude of stresses and environmental conditions while maximizing growth and fitness.
