<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To improve the design performance of long-range guided rockets, a multidisciplinary parametric model of long-range guided rockets was first established to achieve high-precision performance simulation of guided rockets. A sequence approximation optimization method based on an improved augmented radial basis function was proposed, which enhanced the generalization ability of the augmented radial basis function model through anisotropic techniques. Recursive evolution experimental design and fast cross-validation were used to improve the efficiency of approximation modeling, and an imprecise search strategy was applied for sequence sampling. The effectiveness of the proposed optimization method was verified through numerical examples. A sequence approximate optimization design of the long-range guided rocket was carried out, and the maximum range increase by 16.7% compared to before optimization while satisfying design constraints.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To meet the requirements of lightweight and low error sensitivity in the optimization design of stiffened panels, the optimization design of stiffened panels was carried out considering the twist angle error of stringers. The finite element model of post-buckling instability of stiffened panels under axial compression was established, and the sensitivity of the load-carrying capacity to the twist angle error on stringers and the distribution position of the torsional stringer was analyzed. On this basis, a sequential approximate optimization method based on surrogate model was proposed by using parallel sequential sampling strategy, and the lightweight design of stiffened panel was carried out under the influence of twist angle error of stringers. The optimized results show that, compared with the optimization design scheme without error influence, the optimization scheme considering the twist angle error of stringers has lower sensitivity to the twist angle error when the weight is reduced by more than 32%, which can effectively improve the reliability and engineering application value of the optimized structure.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Thermally-induced oscillatory rarefied gas flow inside a two-dimensional rectangular cavity was investigated. The effects of the Knudsen numbers and the oscillation frequency of lid temperature on the flow parameters were analyzed. The Shakhov model equation was solved numerically based on the mesoscopic approach in the near-wall region, and the macroscopic approach was adopted in the bulk flow region to reduce the computational cost. To close the numerical iteration procedure, the velocity distribution functions, served as the pseudo boundary between macroscopic and mesoscopic methods, were reconstructed using the high-order Hermite polynomials. Numerical simulations demonstrate that the temperature profile at the central vertical of the cavity predicted by the hybrid method is in good agreement with results from the mesoscopic method, with maximum error 0.23%. Besides, the computational memory cost can be saved up to about 69.91%. The hybrid approach is able to capture the nonlinear phenomenon in the thermally-induced oscillatory rarefied gas flow under high Kn numbers, where the horizontal velocity no longer obeys the law of periodic oscillating cosine function, and the rise time of the horizontal velocity is much longer than the fall time. The thickness of the viscous penetration layer and the disturbed region increases as the <i>Kn</i> number increases, and decreases as the St number increases.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In monocular vision-guided high-precision inter-platform pose measurement, existing methods require an accurate 3D model of the target platform and are unable to eliminate the impact of 3D model errors on pose measurement. To address this issue, iterative optimization was performed on the 3D model of the target platform and pose, and a new monocular vision measurement method was proposed. Specifically, the target platforms 3D model was modeled using a set of sparse 3D keypoints. By leveraging multi-view geometric constraint information in sequential images, the sparse 3D keypoint set of the target and 6D pose were treated as parameters to be solved. An objective function was established to minimize object-space residuals, and through solving this optimization problem, iterative optimization of the sparse 3D keypoint set and pose was achieved. Additionally, a sliding window combined with a keyframe selection strategy was adopted to realize real-time and online high-precision monocular vision measurement. Experimental results demonstrate that, through iterative optimization of the sparse 3D keypoint set and pose, the proposed method achieves real-time, online high-precision monocular pose measurement under the condition of an inaccurate 3D model of target platform, while simultaneously improving the accuracy of the targets 3D model.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The StS (state-to-state) model and MT(multi-temperature) model were used to numerically simulate and analyze the high-temperature air flow of 11 chemical species behind normal shock waves. The StS model resolved vibrational levels of neutral molecules and electronic levels of neutral atoms; the MT model distinguished the translational-rotational temperature, vibrational temperatures of neutral molecules, and the electron temperature. Simulation results for velocities ranging from 5 km/s to 11 km/s before the shock front demonstrate that immediately behind the shock wave, due to the dissociation and ionization reactions, the higher vibrational levels of molecules and the higher excited electronic levels of atoms are underpopulated relative to the Boltzmann distribution at the corresponding temperatures. Compared to the StS model, the MT model shows that the excitation of vibrational and electronic energies and the attainment of thermal equilibrium in different energy modes occur later, while chemical reactions also take place later but reach chemical equilibrium earlier. The MT model underpredicts vibrational energy loss from chemical reactions while overpredicting electronic energy loss due to electron-impact ionization. Moreover, obtained derived vibrational temperatures of molecules and electron temperature fail to accurately characterize the nonequilibrium population distributions of particle energy levels.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To investigate the effect of interlaminar properties on the tensile properties of fiber hybrid composites, two kinds of epoxy resins with different toughness, 7901 and 9A16, were used as the matrix. Interlayer carbon/glass hybrid composites with different numbers of carbon fiber layers were designed and manufactured. The effects of mode Ⅱ interlaminar fracture toughness (<i>G</i><sub>ⅡC</sub>) on the failure mode and mechanical properties of carbon/glass hybrid composites were investigated through both theoretical and experimental investigation. The results show that, the higher mode Ⅱ interlaminar fracture toughness is, the more the carbon layer tends to fail in fragmentation, achieving a higher critical thickness for fragmentation, which is beneficial for achieving pseudo-ductility. In addition, the GⅡC on the modulus and strength of hybrid composites is marginal, as the variation is within 5%. However, the GⅡC demonstrates a significant impact on the pseudo-ductility strain, which is decreased by 40.7% when the GⅡC is increased from 1.75 N/mm to 2.08 N/mm.]]></description>

These factors have a significant impact on the aerodynamic performance and flight safety of UAV (unmanned aerial vehicle), making them a key focus of research in the field of low-altitude UAV aerodynamics. Three typical scenarios were systematically reviewed: complex low-altitude wind fields, spatially constrained environments, and multi-UAV environments. The fundamental characteristics and modelling approaches of complex low-altitude wind fields were systematically outlined, and their effects on UAV and key research methodologies were summarised. Spatially constrained environments were categorised based on disturbance mechanisms and constraint types, and a comprehensive summary of the aerodynamic impacts on UAV within such environments was provided. The aerodynamic characteristics of UAV in multi-UAV environments were summarised, and the aerodynamic coupling mechanisms and research methodologies for cooperative and non-formation flight scenarios were outlined.

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To address the critical need for autonomous navigation of low-altitude UAVs (unmanned aerial vehicles) in GNSS (global navigation satellite system)-denied environments, a comprehensive survey was presented on absolute visual localization techniques based on a "retrieval-matching-pose estimation" framework. Key challenges inherent to low-altitude UAV observations—including significant imaging disparities, scale variations, and object occlusions—were analyzed, thereby elucidating the advantages of this hierarchical framework for large-scale, long-endurance localization tasks. Subsequently, the technological evolution and state-of-the-art advancements across three core components (cross-view image retrieval, pixel-level feature matching, and UAV pose estimation) were systematically reviewed, tracing the progression from traditional handcrafted features to deep learning paradigms. Finally, considering the deployment requirements of onboard edge computing platforms, the limitations of existing technologies were discussed, and promising future research directions were outlined. This survey is intended to serve as a valuable reference for both research and practical applications in absolute visual localization for low-altitude UAVs.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Recent advances in information technology and new energy systems have introduced increasingly stringent requirements for regulating energy transport within materials. Conventional material-design paradigms are limited by inherent trade-offs among optical, thermal, and electrical transport properties, creating an urgent need for a new paradigm to fundamentally decouple and reconstruct material functionalities. Recent progress on nanoporous aerogels as an enabling platform was systematically summarized, emphasizing how hierarchical structural design and cross-scale assembly of building units allow precise control of diverse energy-carrier transport. Based on this theoretical framework, advanced applications in photo thermal electrical energy conversion were highlighted, with particular emphasis on research progress and performance optimization pathways of aerogels for photothermal, photoelectric, thermoelectric, and integrated photo thermal electric systems. Finally, future research directions including AI-driven inverse design and synergistic regulation of multiple energy carriers were outlooked, providing new perspectives for the on-demand development of next-generation high-performance photo-thermal-electrical conversion materials.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[With the increasing number of space activities, HVI (hypervelocity impacts) caused by space debris and micrometeoroids have become a major threat to the safety of spacecraft in orbit. Such collisions not only result in mechanical damage but also generate plasma, whose electromagnetic effects pose severe risks to highly integrated spacecraft electronic systems. A systematic review of plasma physical effects induced by hypervelocity impacts was provided.The review covered the mechanisms of plasma generation, kinetic characteristics, electromagnetic radiation, and induced discharge, encompassing both theoretical and experimental progress. Special emphasis was placed on the introduction of condensed-phase products (dust grains) in hypervelocity impacts and the resulting dusty plasma effects. This review aims to offer researchers in the field a comprehensive literature summary and to highlight key scientific questions and future research directions. Ultimately, it seeks to provide theoretical support for enhancing the survivability of spacecraft in orbit and for developing next-generation electromagnetic protection technologies.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[During the high-speed flight of aircraft, raindrop impact erosion causes significant damage to surface materials, thereby seriously affecting flight performance and structural safety. This paper is aimed to systematically review the mechanical mechanism, key influencing factors, and progress in corresponding protection technologies of high-speed raindrop impact erosion. In terms of experiments, current studies mainly rely on devices such as wind tunnels, rocket sleds, and rotating arms to construct simulated environments of real rain fields. Meanwhile, high-speed photography is used to record the dynamic erosion process, and laser velocimetry is employed to obtain raindrop impact velocity, thus achieving multi-dimensional observation of erosion behavior. In terms of numerical simulation, it was focused on introducing mainstream simulation techniques such as the finite element method and the smoothed particle hydrodynamics method. Additionally, an overview was provided of existing research methods and outcomes, which primarily involve establishing liquid-solid coupling models to analyze the propagation patterns of stress waves and the dynamic response characteristics of materials during impact processes. The research results show that raindrop impact velocity, impact angle, and mechanical properties of materials are the key factors affecting the erosion rate. Based on the actual flight envelope parameters of aircraft, targeted optimization design of rain erosion resistance performance can be carried out, which can provide a theoretical basis and technical support for improving the service safety of aircraft in harsh meteorological environments.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To predict the boundary-layer transition location over a flat plate across varying Mach numbers, an efficient method was developed for small-sample settings. Flow-field disturbance datasets across multiple Mach numbers were generated using the nonlinear parabolized stability equations, with Ma=0.01 designated as the source domain and Ma=0.1, 0.2, 0.4, 0.8, 1.6 as target domains. The influence of Mach number variations on transition patterns was systematically analyzed. A convolutional neural network model was employed to map flow field patterns to transition locations, incorporating a transfer learning strategy with progressive unfreezing and layer-wise learning rates. Results demonstrate that transfer learning significantly outperforms direct training: for Ma≤0.4, only 1/10 of the target domain samples are required to achieve a mean absolute error below 2.04% of the average ground-truth value; for Ma≥0.8, a progressive domain adaptation strategy controls the error within 6.19%. The approach enhances transition prediction under small-sample conditions and provides a reliable technical pathway for cross-condition flow modeling.]]></description>
