Research ArticleOpen accessIn the keywordsAbrasive Jet Polishing and its Applications in Surface FinishingZhaoze Li, Jianmin Wang, Xiaoqiang Peng et al.Problem statement: Single Point Diamond Turning (SPDT) is highly deterministic and versatile in producing various forms of precise optics. A typical example is the production of large off-axis aspheric mirrors and various infrared mirrors and mandrels. However, the fine periodical turning marks left in the surface critically limit its performance and they are difficult to be avoided for traditional polishing … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 26 Jul 2011 · 13,587 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMANAT: A Filtering-Based Method for Denoising Nonuniform Photogrammetric Point CloudsYun Sin Chong, Hui Hui Wang, Yin Chai WangThree-dimensional point clouds reconstructed from photogrammetry often exhibit noise and non-uniform sampling density, which challenges existing denoising methods that rely on precise normal estimation or extensive parameter tuning. This study presents the Multi Attribute Neighbour Attraction Technique (MANAT), a novel single-stage, density-adaptive filtering method that jointly leverages spatial position, surface normals, and color as inherent photogrammetric attributes for unified noise … …Journal of Computer Science, Vol. 22, Issue 4 · 28 Apr 2026 · 1,524 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDF Cite

Case ReportOpen accessIn the abstractHistopathology of Microbially Induced Corrosion and Cluster Failure of Moderately Rough Surface Oral Implants in a Resident Bone MicrobiotaStephen Nelson, Helen Hu et al.This case report presents as a maxillary "cluster-failure", where six moderately rough-surface oral implants (1-2 microns) were installed to support a full-arch hybrid bridge. Understanding cluster failures requires the acknowledgment of biofilm science that recognizes the persistence of bacterial infection in bone following extraction and the need to bioremediate the bone-bed, by surgical debridement, before implant installation. The patient, a … …Current Research in Dentistry, Vol. 15, Issue 1 · 28 Feb 2024 · 8,482 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 abstractEffect of Varying Loads on Wear Behaviour of Constructional SteelAlo Francis Ireti, Emordi Ngozi, Kunle Michael Oluwasegun et al.This study examined the effect of varying loads on wear behaviour of Ife constructional steel. The wear measurements were determined under normal ranging from 5 to 25 N at interval of 5 N incremental. The morphology of the corroded samples were carried out using optical microscopy and Scanning Electron Microscopy (SEM). When a load of 5 N was used, the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 6 Feb 2018 · 7,574 accessesView PDF Cite
