https://gup.ugal.ro/ugaljournals/index.php/mms/article/view/9233
<p>The analysis and detection of patterns in textile materials are a critical challenge in modern manufacturing, quality control, and automation processes. Traditional inspection methods, often reliant on manual observation, are not only time-consuming but also prone to inconsistencies. The need for a more precise, efficient, and scalable approach has driven interest in leveraging computer vision for this task. Computer vision systems, powered by advanced algorithms and machine learning models, offer the ability to process and interpret visual data from textile images at high speeds and with greater accuracy.</p> <p><a href="http://creativecommons.org/licenses/by-nc/4.0/"><img src="https://i.creativecommons.org/l/by-nc/4.0/88x31.png" alt="Creative Commons License"></a></p>Mihaela MARINFlorin-Bogdan MARIN

2025-06-152025-06-1548291310.35219/mms.2025.2.02Assessment Using Numerical Analysis of the Behaviour of a Two Fingers Gripping Mechanism
https://gup.ugal.ro/ugaljournals/index.php/mms/article/view/9235
<p>An important issue in robotics is evaluating the force necessary to firmly grip objects. This can be done experimentally, or, as a more cost-effective approach, through numerical analysis. The results obtained through this method, although less precise, can offer a good assessment of the way a gripping mechanism behaves. The authors propose a comparative numerical analysis of a two-finger gripper, using a motion analysis performed in Siemens NX and a transient structural analysis conducted in Ansys. Both methods aim to capture the moment when the grasped object starts to slip. This moment marks the point at which the gripping is no longer reliable and provides insights into the reliability of the gripping mechanism. To assess the influence of the geometry of the gripping area, as well as the impact of the shape of the grasped object or the pair of materials (object and gripper), several analyses were performed in both Siemens NX and Ansys Workbench.</p> <p><a href="http://creativecommons.org/licenses/by-nc/4.0/"><img src="https://i.creativecommons.org/l/by-nc/4.0/88x31.png" alt="Creative Commons License"></a></p>Ionuț LAMBRESCUMihai Bogdan ROTH

https://gup.ugal.ro/ugaljournals/index.php/mms/article/view/9236
<p>To be kept in use, pipelines with Volumetric Surface Defects (VSDs) must be evaluated and, if necessary, repaired. The first step in the repair process is machining the defect area. In all cases, the machined defect has a rectangular shape, with edges parallel/perpendicular to the pipe axis. We propose a novel approach: the VSD is scanned, the image is then processed using segmentation techniques, the VSD contour is detected, and finally, a family of rectangles with minimal area enclosing the VSD is defined. After that, a Finite Element Analysis is performed for each machined VSD, and an optimal case is selected.</p> <p><a href="http://creativecommons.org/licenses/by-nc/4.0/"><img src="https://i.creativecommons.org/l/by-nc/4.0/88x31.png" alt="Creative Commons License"></a></p>Ionuţ LAMBRESCU

https://gup.ugal.ro/ugaljournals/index.php/mms/article/view/9237
<p>The selection of structural adhesives in engineering applications demands a robust, transparent, and replicable methodology, especially when performance and reliability are critical. This study introduces a practical, scalable approach based on the Weighted Sum Method (WSM), a form of Multi-Criteria Decision Analysis (MCDA), to assist in the objective selection of adhesives. The novelty of this research lies in demonstrating that WSM can serve as an industrially applicable decision-making tool that translates mechanical testing data into clear, replicable selection criteria. Using experimental data from modified Arcan tests, the method provides a structured framework that can be extended to other types of tests and applications. This facilitates transparent, criterion-driven adhesive selection aligned with real-world constraints, offering engineers a powerful tool that supports consistent, informed, and reproducible decisions.</p> <p><a href="http://creativecommons.org/licenses/by-nc/4.0/"><img src="https://i.creativecommons.org/l/by-nc/4.0/88x31.png" alt="Creative Commons License"></a></p>Andreea ȚÎNTATU
