Applied Sciences, Vol. 16, Pages 9092: DSM-Based Quantitative Comparison of Centralized and Modular Architectures of a Field-Deployed Electrohydraulic Lifting Device, Validated by Prototype Experiments
19+ hour, 32+ min ago (495+ words) Steel storage tanks are erected on site by multi-cylinder hydraulic lifting, conventionally from one power unit feeding all cylinders through a flow divider. Decentralized alternatives have not been evaluated for this task, and modularity in fluid power is rarely quantified....
Applied Sciences, Vol. 16, Pages 9078: Backstepping Angle Control of a Marine Hydraulic Ramp Based on a Nonlinear Extended State Observer
1+ day, 59+ min ago (460+ words) Marine hydraulic ramps exhibit pronounced nonlinear behavior arising from configuration-dependent transmission geometry, gravitational torque, and servovalve flow–pressure coupling. Accurate angle regulation is further complicated by external disturbances and unavailable internal states. This study develops a nonlinear extended state observer…...
Applied Sciences, Vol. 16, Pages 9051: An Efficient Trajectory Planner for Fixed-Wing UAVs via Improved A*-Guided Initialization
2+ day, 2+ hour ago (165+ words) This study proposes an efficient trajectory planning method for fixed-wing unmanned aerial vehicles (UAVs) based on an improved A*-guided initialization strategy for complex obstacle environments. An improved three-dimensional A* method is developed to generate smooth and collision-free global paths…...
Applied Sciences, Vol. 16, Pages 8879: Point Cloud-Based Weld Seam Recognition and Localization for Robotic Welding
6+ day, 22+ hour ago (477+ words) The identification and spatial positioning of welds are key links in welding process matching and automatic welding path planning. Therefore, achieving automatic recognition and spatial positioning of weld point cloud features under online scanning imaging conditions is of great significance…...
Applied Sciences, Vol. 16, Pages 8706: Genetic–Neural Adaptation of the Kalman Filter Process Noise Covariance for Dynamic Tracking in Electro-Pneumatic Systems
1+ week, 5+ day ago (411+ words) This paper proposes a hybrid machine-learning approach based on the genetic-neural online adaptation of the process noise covariance matrix in an adaptive Kalman filter, designed to improve the accuracy of dynamic tracking in electro-pneumatic systems. The method combines offline parameter…...
Applied Sciences, Vol. 16, Pages 8664: Design of a Translational Flexible Truss Based on Distributed Guide-Slot Optimization
1+ week, 6+ day ago (298+ words) This paper presents a proof-of-concept study of a translational self-deployable flexible truss with distributed spherical guide-slots. A constrained trajectory-design procedure is developed by integrating guide-slot parameterization with flexible multibody dynamics. A two-stage optimization strategy is implemented, where the stowed compactness…...
Applied Sciences, Vol. 16, Pages 8623: From Fidelity to Efficiency: A Review of Modeling and Simulation for Flexible Needle Insertion
2+ week, 1+ day ago (258+ words) This review provides a comprehensive synthesis of the field’s evolution along two complementary axes, organized as a dual-axis chrono-spatial framework that reimagines how computational methods in medicine can be understood. The longitudinal axis, the temporal dimension, traces the chronological progression…...
Applied Sciences, Vol. 16, Pages 8418: A Feasibility Study of Deep Learning-Based Motor Defect Screening in a Production Line Using an Airborne Acoustic Signal
2+ week, 6+ day ago (377+ words) Reliable defect detection in motor production lines is important for maintaining manufacturing quality. This study investigates the feasibility of a deep learning-based airborne acoustic screening approach for controlled no-load end-of-line induction motor inspection. Acoustic signals collected under controlled no-load test…...
