Augmented reality (AR) has increasingly been used in varying activities by superimposing visual instructions on the workbench directly. Nevertheless, most current AR deployment is mainly first-person perspective, and it is difficult for colleagues to observe the other's operating intent directly when involving co-located users in complex environments, such as collaborative AR assembly. To this end, this paper tries to propose a co-located alignment-enabled mobile collaborative AR system. Instead of the commercial AR glass, we first establish a self- contained visual-inertial odometry system for mobile hand- held devices, and it can realize markerless pose estimation for mobile objects and enable the foundation for easy-to-deploy applications. Then, a collaborative alignment framework from multi co-located AR clients is proposed, and thus the unified global coordinate system is available for a shared immersive AR workplace on the shop floor. Finally, extensive experiments are carried out on the motion tracking and collaborative AR experience, and experimental results illustrate the effectiveness and feasibility of the proposed system. © 2023 IEEE.

The electro-hydrostatic actuator (EHA) has the advantage of high power weight ratio, less leakage and the absence of throttle loss. It's used on the multi-electric aircraft and the all-electric aircraft. However, it will be affected by the aerodynamic load and the rudder flutter will occur if the dynamic stiffness of the EHA is low. As a result, it's significant to analyse the sensitivity of the EHA's parameters on the dynamic stiffness. The article builds a linear model of the EHA considering the leakage in the system. What's more, the local parameter sensitivity for the dynamic stiffness is calculated when the frequency is between 0.01 Hz and 1000 Hz. © The Institution of Engineering & technology 2024.

Rolling bearing failure will affect the normal operation of the mechanical equipment. Effective early failure diagnosis can avoid unnecessary losses caused by bearing fault. A fault diagnostic method of rolling bearing relying on Feature Mode Decomposition (FMD) and Convolutional Neural Network (CNN) is proposed in this article. Firstly, the effective fault feature information in rolling bearing vibration signal will be extracted by FMD method, and then the collected feature information is introduced into the CNN framework to effectively classify different types of faults of rolling bearing. This method is of practical significance for the fault classification of rolling bearing under the strong background noise.

Highly dispersed Pt-based single-atom alloys have been extensively studied in heterogeneous catalysis,particularly for propane dehydrogenation(PDH).However,Pt-based single-atom alloys still suffer from sintering and coke deposition in high-temperature dehydrogenation ***,the atomic structure of the active sites of Pt-based single-atom alloys for PDH remains elusive,and the solid chemistry occurring on the catalyst surface is still under *** this work,we discovered that the coordination environment of the single Pt atom for Pt_(1)Cu_(30)cluster catalysts,encapsulated with a carbon layer,can be regulated by sequential heat treatment under air and H_(2)*** Pt_(1)Cu_(30)cluster catalyst,with a single Pt atom coordinated by 9 Cu atoms,is similar to the surface structure of Pt_(1)Cu_(3)(111)and exhibits excellent catalytic activity and stability at high temperatures,maintaining propane conversion of 43.5%and propylene selectivity of 98.2%,with a deactivation constant(Kd)of 0.01 h^(−1),even after 32 h of testing at 600℃.The combination of structural characterizations and temperature programmed analysis reveal that the single Pt atom coordinated by around 9 Cu atoms of the Pt_(1)Cu_(30)cluster catalyst,serves as the vital active sites for C-H cleavage of propane and propylene desorption due to their electron-rich and geometrically isolated Pt atom ***,the thin carbon layer coated on the surface of Pt_(1)Cu_(30)clusters can effectively reduce the desorption energy of propylene,thereby avoiding further dehydrogenation and improving the propylene yield and catalytic stability.

Spectral technology is one of the key means for long-distance non-contact detection and identification of materials. It is an important force for ground-based detection satellites which can play a role in monitoring satellite operation status and safety, and identifying satellite types except for radar. However, for complex targets detected at ultra long distances, the detection object is equivalent to a point source, and the distribution of surface materials is not clear. Usually, material spectral unmixing can only focus on the distribution of planar materials, making it difficult to analyze the target structure. This article uses the spectral BRDF function to construct a hyperspectral ray tracing rendering 3D representation method based on the relationship between illumination, target surface normals, and detection points. It obtains a 3D rendering of a single material on a composite target, laying the foundation for analyzing the structural features of long-distance point target detection. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

In nuclear reactors,the irradiation of metal materials by high-energy particles results in a substantial number of point defects,i.e.,vacancies and interstitials[1-3].High-density accumulation of point defects leads to the formation of defect clusters,including voids,bubbles,and dislocation loops[4-6].These radiation defects contribute to the degradation of structural integrity and perfor-mance,such as hardening,embrittlement,swelling,and surface de-terioration[7-9].Therefore,the regulation and elimination of radi-ation defects have been a long-standing and serious challenge for nuclear materials.
