This paper presents an innovative approach to identifying defects in alloy wheel production by integrating image processing techniques with a mobile application platform. The system receives X-ray alloy images from the factory via mobile phone, processes them using image processing techniques to enhance clarity and readiness for defect detection, and then transmits the processed images to a Django framework via a uniform resource locator (URL). Subsequently, the system detects defects in the images, encodes them in Base64 format, and sends them to the mobile application through an API (Application Program Interface) for display on the user interface. This well-designed system architecture offers manufacturers a comprehensive solution to ensure product quality, reduce costs, and enhance customer satisfaction.

Recently we introduced a local photon approach for modelling the quantised electromagnetic field in position space. Using this approach, we define the momentum of light in this paper as in quantum mechanics as the generator for spatial translation. Afterwards, we analyse the momentum dynamics of photonic wave packets which transition from air into a denser dielectric medium. Our analysis shines new light onto the Abraham-Minkowski controversy which highlights the intricacies involved in the characterisation of the momentum of the electromagnetic field. Although our results align with Minkowski’s theory and with the definition of the canonical momentum of light in quantum electrodynamics, there are also some crucial differences. © 2024, CC BY.

Oxygen evolution reaction (OER) is one of the important anodic reactions in most of widely used electrochemical conversion devices . However, the four-electron transfer process in OER makes the reaction sluggish and reduces the efficiency accordingly. Although a lot of OER electrocatalysts have been developed, the actual active sites after the surface reconstruction during OER, which play crucial role in the catalytic performance, have not been fully understood. Herein, we find that the distorted FeOOH/Ni hydroxide on Ni foam (NF) (d-FeOOH/Ni hydroxide-NF) shows better electrochemical performance than crystalline FeOOH/Ni hydroxide-NF (c-FeOOH/Ni hydroxide-NF) because the interfaces in d-FeOOH/Ni hydroxide-NF, which are the key active sites for OER, are well maintained during the reaction compared with c-FeOOH/Ni hydroxide-NF, leading to promoted catalytic performance and long-term stability at high current density. By using in-situ and ex-situ techniques, we show that the structure rearrangement in electrocatalyst results in small crystal size and high Lewis acidity of Fe and Ni atoms in d-FeOOH/Ni hydroxide-NF, which endows high flexibility of the lattice and tolerates the volume expansion during OER greatly. Therefore, the well-maintained FeOOH/Ni hydroxide interface promotes the OER with excellent electrochemical performance (an overpotential of 1.50 V at 100 mA cm -2 and long-term durability for 32 hours at 425 mA cm -2 ), which outperforms most of the state-of-the art electrocatalysts. Our study may provide an insightful understanding on the catalytic performance of Fe-Ni based electrocatalysts and guidance for their design and synthesis for practical application. © 2022, The Authors.

We explore the existence of spin glass phase in FeCo/FePt bilayers arising due to disordered ferromagnet. The non-ergodic and highly degenerate landscape of the spin glass phase at low temperature explains the origin of complex magnetic texture in the FeCo/FePt system. Upon cooling the bilayered system, the magnetic texture undergoes spin freezing below 120 K as evident from the bifurcations in zero field cooling and field cooling magnetizations at low magnetic field as a manifestation of broken ergodicity. The uncompensated magnetic moments originating in the spin glass state result in slow time dynamics of thermoremanent magnetization. Consequently, the bilayers demonstrate an intriguing magnetic memory effect in which the magnetic state of the system could be retrieved upon isothermal ageing below 120 K after reversing the temperature cycle. Thermal treatment deteriorates the spin glass behaviour and shows a transition to strong ferromagnetic character in FeCo/FePt bilayers. © 2024 IOP Publishing Ltd.

We construct a new explicit family of good quantum low-density parity-check codes which additionally have linear time decoders. Our codes are based on a three-term chain pFm2*mqV ÝÑ δ0 pFm2 qE ÝÑ δ1 FF2 where V (X-checks) are the vertices, E (qubits) are the edges, and F (Z-checks) are the squares of a left-right Cayley complex, and where the maps are defined based on a pair of constant-size random codes CA, CB: Fm2 Ñ F∆2 where ∆ is the regularity of the underlying Cayley graphs. One of the main ingredients in the analysis is a proof of an essentially-optimal robustness property for the tensor product of two random codes. © 2022, CC BY.

We investigate the effect of density perturbations and local anisotropy on the stability of stellar matter structures in general relativity using the concept of cracking. Adopting a core-envelope model of a super-dense star, we examine the properties and stability conditions by introducing anisotropic pressure to the envelope region. Furthermore, we propose self-bound compact stars with an anisotropic envelope as a potential progenitor for starquakes. We show how the difference between sound propagation in radial and tangential directions would be used to identify potentially stable regions within a configuration. Due to an increase in the anisotropic parameter, strain energy accumulates in the envelope region and becomes a potential candidate for building-up quake like situation. This stress-energy stored in the envelope region that would be released during a starquake of a self-bound compact star is computed as a function of the magnitude of anisotropy at the core-envelope boundary. Numerical studies for spherically asymmetric compact stars indicate that the stress energy can be as high as 1050 erg if the tangential pressure is slightly more significant than the radial pressure. It is happened to be of the same order as the energy associated with giant γ-ray bursts. Thus, the present study will be useful for the correlation studies between starquakes and GRBs. © 2023, CC BY.

In this study, we prepared five brick samples based on clay (C), granite (G), laterite (L), basalt (B) and assessed their radiation shielding performances. The densities of the bricks were calculated by dividing the mass of each sample by their volumes. The X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray techniques (EDX), differential thermal analysis (DTA), and thermogravimetric analysis (TGA) were respectively used to identify the crystal structure, morphological structure, chemical composition, and thermal behaviour of the prepared bricks. The radiation shielding properties of prepared brick samples were examined to check the ability of the prepared materials in attenuating the gamma-ray photons. At 0.033–2.506 MeV, basalt and granite bricks have the highest linear attenuation coefficient, of 22.332-0.097 cm−1 (for basalt bricks) and 35.633–0.096 cm−1 (for granite bricks) among the prepared bricks. The study shows that basalt and granite brick samples have suitable shielding properties. © 2025 Elsevier Ltd

The current research concentrated on the Co-precipitation synthesis of g-C3N4 (CN), ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposite, as well as the solar light enhanced photocatalytic treatment of Reactive Red 120 (RR120) from genuine wool textile effluent. The 3D flower-like structure of Co-doped ZnO distributed on the surface of CN thin sheets, according to structural studies employing XRD and SEM examinations Electrochemical experiments exhibited that the Co-doped ZnO/CN nanocomposite has a large electroactive surface area. The optical band-gap values of CN, ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposites were 2.68, 3.13, 2.38, and 2.23 eV, respectively, according to optical characterizations. The synergistic effects and heterojunction produced by Co-doped ZnO and CN can be linked to the narrow gap in nanocomposites. After 75, 60, 50, and 40 min of exposure to solar light, photocatalytic degradation assays for 250 mL of 20 mg/L RR120 solution in the presence of CN, ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposites demonstrated 100% dye treatment. The applicability of photocatalysts for decolorization of 250 mL of 10 mg/L RR120 prepared from actual wool textile wastewater was investigated, and the results showed that Co-doped ZnO/CN nanocomposites for treatment of RR120 from actual wool textile wastewater were highly efficient at photocatalytic degradation. © 2023

Magnetic vortices are topological spin structures frequently found in ferromagnets, yet novel to antiferromagnets. By combining experiment and theory, we demonstrate that in a nanostructured antiferromagnetic-ferromagnetic NiO(111)-Fe(110) bilayer, a magnetic vortex is naturally stabilized by magnetostatic interactions in the ferromagnet and is imprinted onto the adjacent antiferromagnet via interface exchange coupling. We use micromagnetic simulations to construct a corresponding phase diagram of the stability of the imprinted antiferromagnetic vortex state. Our in depth analysis reveals that the interplay between interface exchange coupling and the antiferromagnet magnetic anisotropy plays a crucial role in locally reorienting the Néel vector out-of-plane in the prototypical in-plane antiferromagnet NiO and thereby stabilizing the vortices in the antiferromagnet. © 2024, CC BY.
