Research ArticleOpen accessIn the keywordsMachine Learning Approach for Defects Identification in Dissimilar Friction Stir Welded Aluminium Alloys AA 7075-AA 1100 JointsAkshansh MishraMachine learning approaches are now applied in various manufacturing industries. Various machine learning algorithms can be implemented for prediction of the particular mechanical properties like Ultimate Tensile Strength (UTS), Elongation percentage and fracture strength of the given mechanical component and also image processing algorithms can be applied for defects detection in the mechanical components. In our recent work, we have … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 1 Jul 2020 · 6,701 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCapsule Defect Detection and Classification Using Enhanced MobileNet ModelWenqing Bian, Yongzhi Huang, Baolian Shan, Yanting ChangThe quality of capsules has a direct impact on human health. However, defects inevitably arise during the capsule manufacturing process, and manual sorting is required. Most studies on capsule defects focus on detecting surface imperfections and those on internal capsule defects remain relatively limited. This study classifies four types of capsules using the deep learning model MobileNet, aiming to accurately … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 5 Nov 2024 · 5,203 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Method for the Non-Destructive Assessment of Strength Degradation and Re-Use Potential of Weathered Float Glass From Facades: A Proof of Concept StudyFred Veer, Mauro Overend, Irene Sofokleous, Chris NoteboomLack of knowledge about the properties of weathered (used) glass is currently a major barrier to glass reuse. This results in probably unnecessary recycling or down-cycling of architectural glass at the end of life. Avoiding this creates a significant opportunity to reduce resource depletion and decarbonize the built environment. This can be done by developing an optical non-destructive test method … …International Journal of Structural Glass and Advanced Materials Research, Vol. 7, Issue 1 · 19 Oct 2023 · 9,292 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLocal Binary Pattern for the Evaluation of Surface Quality of Dissimilar Friction Stir Welded Ultrafine Grained 1050 and 6061-T6 Aluminium AlloysAkshansh Mishra, Rajat SarawagiFriction Stir Welding process is an advanced solid-state joining process which finds application in various industries like automobiles, manufacturing, aerospace and railway firms. Input parameters like tool rotational speed, welding speed, axial force and tilt angle govern the quality of Friction Stir Welded joint. Improper selection of these parameters further leads to fabrication of the joint of bad quality resulting … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 27 Jul 2020 · 6,228 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDefect Detection on 3D Print Products and in Concrete Structures Using Image Processing and Convolution Neural NetworkSelorm Garfo, M.A. Muktadir, Sun YiThis paper explores the automated detection of surface defects on 3-D printed products and concrete structures. They are the main factors to evaluate their quality in addition to dimension and roughness. Traditional detection by human inspectors is far from satisfactory. Manual inspection is time-consuming, error-prone and often leads to loss of resources. For this purpose, image processing and deep learning-based … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 26 May 2020 · 12,608 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessing and Improving the Performance of Grouted MacadamMomtaz M. Othman, Ahmed Ebrahim Abu El-Maaty, Zeinab S. HusseinThere are many road defects appear in flexible pavement layers. Rutting, raveling and cracks are considered the main problems in Egypt. Using grouted macadam system as a surface asphaltic layer (or called Semi-Flexible Pavement (SFP)) has many advantages such as saving the natural asphalt and enhancing the performance against deteriorations. The main scope of this research is to evaluate and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,078 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Optimization of a Porous Ti6Al4V Bone Construct Using Additive ManufacturingJeffrey Wilk, Glenn Sanders, Shelby Marks et al.Patient specific implants are becoming viable treatment options in some orthopaedic applications through advances in additive manufacturing and 3D printing techniques. One potential application is for treatment of segmental bone defects, particularly in patients suffering from bone cancer. Current treatment options are: Amputation, megaprosthesis, or allografts. These treatments are often highly invasive, may require a partial/full joint replacement and are … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 2 Jan 2017 · 7,811 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMultiaxial Fatigue Strength to Notched specimens made of 40CrMoV13.9Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu et al.Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,200 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Process of Porous Tantalum Implants Osseous Integration a ReviewChristos G. Paganias, George A. Tsakotos, Stephanos D. Koutsostathis, George A. MacherasPorous tantalum is a biomaterial that was recently introduced in orthopaedics in order to overcome problems of the past related to implant loosening. Its use has led to very good results, especially in difficult cases where severe bone defect is present, as it is found to have osteoconductive and possibly, osteoinductive properties. So, it is of great interest to shed … …Current Research in Medicine, Vol. 5, Issue 2 · 22 Apr 2015 · 7,847 accessesView PDF Cite
