Single Point Incremental Forming (SPIF) is a flexible and cost-effective sheet metal forming process; however, its industrial application remains limited due to fixture systems that do not fully satisfy production requirements. This study presents the design, fabrication, and ex…

This article presents the simulation and evaluation of a Deep Learning-integrated control system for the UR5 robot, enabling shape classification and multi-object pick-and-place in the CoppeliaSim environment. The system combines a vision sensor camera, a YOLO Detection model, p…

The camshaft is a component operating under high contact loads and severe friction conditions; therefore, the cam lobe surface is highly susceptible to wear. High Velocity Oxygen Fuel (HVOF) spraying technology is considered an effective solution for restoring and extending the…

Thread trimming after sewing is an essential but challenging step due to the high cutting force, dependence on the thread type and the use of inefficient crude cutting tools. This research establishes a theoretical basis and analyzes the influence of blade geometry on the cuttin…

The tracking performance of robot manipulators is often compromised by dynamic uncertainties, external disturbances, and actuator nonlinearities such as dead zones. To overcome these issues, this study introduces a robust adaptive control framework that combines sliding mode con…

The paper proposes a variant of the Ant Colony Optimization (ACO) algorithm with a H/F hierarchy (from nest and from bait) combined with a bidirectional pheromone update. The method uses a breadth-first search (BFS) algorithm to assign H-layer and F-layer distance classes, there…

Modern retrieval-augmented generation (RAG) systems typically rely on semantic similarity to retrieve context for large language models (LLMs). However, this approach often returns passages that lack factual relevance, leading LLMs to produce unsupported answers. To address this…

This study aimed to select lactic acid-producing Lactobacillus strains that were stress-tolerant to environmental stress conditions from fruit peel by-products including Cayenne pineapple (Ninh Binh), Taiwanese papaya (Hanoi), white-fleshed dragon fruit (Binh Thuan), Dien pomelo…
