With the continuous evolution of information-based and intelligent warfare, the appearance and identification design of military equipment have gradually shifted from a singular focus on recognition functions to multi-dimensional information expression and situational awareness. As a comprehensive reflection of national military strength and technological capabilities, the surface patterns of military aircraft not only perform traditional tasks such as camouflage, identification, and psychological deterrence, but have also progressively developed into an important medium for conveying organizational culture, technological aesthetics, and strategic awareness. This paper, supported by the theory of “Situational Awareness,” systematically reviews the evolution paths and design logic of military aircraft patterns across different periods, based on the research perspectives of design morphology and cultural semiotics. The study first establishes an analytical framework covering four dimensions: technological background, task types, environmental factors, and cultural symbols, and conducts systematic sampling and graphic element deconstruction of representative aircraft models from typical countries (such as the United States, Russia, and China). By combining the quantification of morphological characteristics with semantic classification methods, the study extracts the main components involved in pattern design, including color systems, geometric language, composition methods, and visual guidance mechanisms. On the basis of comparative analysis, the paper further reveals the three-phase evolutionary trend of military aircraft patterns: from the “function-oriented camouflage period” to the “recognition-oriented marking period,” and then to the “information-oriented situational period.“ This evolution reflects not only the co-evolution of material processes, task scenarios, and aesthetic concepts but also the trends of “cognitive visualization” and “information narration” in modern military design. The research results indicate that, with the application of multi-source sensing and human-machine collaborative technologies, future military patterns will increasingly emphasize dynamic perception and intelligent response characteristics, transitioning from static visual symbols to situational information interfaces. The innovation of this paper lies in its focus on situational awareness as the core and the establishment of a pattern evolution analysis model for the military design field, achieving a cross-domain integration from perceptual form recognition to rational cognitive extraction. The study not only provides a systematic theoretical basis for military equipment visual design but also offers a reference direction for the intelligent camouflage and information expression of next-generation military products. By integrating design research with the development of military craftsmanship, this paper attempts to explore a fusion path between military aesthetics and situational intelligence, providing sustainable design foundations for the construction of future military visual systems.
In the development of virtual prototyping for rail vehicles, industrial design plays a bridging role between art and engineering. In the present industrial design process, on account of problems such as too many types of software were used and difficulties in model conversion, the research proposes a collaborative design method for industrial design based on the 3DE platform, aiming to establish a unified “3D data mainline” to achieve continuous development of industrial design and engineering design. Taking a certain urban rail vehicle as an example, the industrial design procedure is analyzed, including demand input, rapid modeling, real-time rendering, curve modeling, etc. It is hoped that this method can reduce development costs, shorten the time cycle, and improve work efficiency in the development process of virtual prototyping for rail vehicles.
Aligning designer requirements with prototyping platform functionalities remains a challenge in agile development (AD) environments, as existing tools often fail to accommodate evolving needs. This study proposes a systematic approach to optimizing prototyping platforms by bridging the gap between user needs and functional design. First, a designer requirement architecture was constructed using grounded theory, identifying three core elements: interaction needs, collaboration needs, and visualization and testing needs. The F-KANO model was used to categorize requirements, while DEMATEL was used to prioritize them based on interdependencies. Finally, quality function deployment (QFD) was used to map designer needs to functional specifications, deriving an optimization strategy. Empirical evaluation through user testing indicated notable improvements in workflow efficiency, usability, and collaboration effectiveness. This research offers a systematic framework for refining prototyping platforms in AD, improving design efficiency and UX.

The rationality of the scheme was verified, and interface design paradigm was constructed based on intelligent technology.Conclusion After improving the design, the interface effectively reduced the frequency of problems and average skilled operation time, thereby, improving the subjective satisfaction score of users.
Portable stroke diagnostic devices for pre-hospital detection are crucial for improving stroke treatment rates, but most existing devices are too large and difficult to move, delaying diagnosis and treatment. This study uses a method to analyze and transform user needs into the design of a portable stroke detection device for quick pre-hospital diagnosis and timely treatment. Firstly, user needs from doctors, nurses, patients and patients' families were collected through surveys and online searches and organized using the KJ method. The AHP method, FAST model and QFD theories were used to prioritize these needs, translate them into design elements and establish the importance of each element. Finally, the primary and secondary design elements of the device were identified through qualitative and quantitative analyses, considering ergonomics, user behavior, technology and structure. The study shows that the AHP/FAST/QFD integrated method can effectively guide the design of portable stroke detection devices, providing valuable insights for related product designs.

AbstractTo expedite the modernisation of equipment construction and address practical challenges, such as low efficiency in armoured vehicle passenger information retrieval, diverse perception channels, and inadequate combat effectiveness in traditional vehicle‐integrated electronic information systems, the authors aim to transition to a helmet‐mounted display system (HMD). On the basis of the target mission stage of military vehicles, the authors have organised the required information items for the vehicle HMD, integrated the hierarchical relationships of interaction interface design elements, and formulated design strategies using the Garrett user experience element model. We have constructed a vehicle HMD interaction interface design model and conducted comparative experiments with typical vehicle electronic display system interfaces. The usability of the model has been verified through eye‐tracking experiments and reaction time analysis. Experimental data indicates that the vehicle HMD interactive interface system, guided by the user experience element model, effectively enhances operational performance for passengers, demonstrating superior recognition, search ability, comprehensibility, and rationality. In conclusion, the vehicle HMD interaction interface design model, guided by the user experience element model, meets the requirements of vehicle HMD interaction interface design. It validates the effectiveness and feasibility of transitioning from a traditional vehicle‐integrated electronic information system to a vehicle HMD, providing technical support for enhancing display efficiency in future prototype platforms on the prototype platform digital warfare.
As the number of traffic accident casualties continues to rise globally, this study aims to enhance traffic safety during highway emergency repairs. Based on the fundamentals of human vision, this study designed a novel interactive barricade design, R-barricade, which aims to improve the visibility and warning effect of the barricade, as well as to enhance the interaction with the operator in order to reduce the risk of accidents. We established a comprehensive visual criteria framework, combined with eye-tracking technology, to systematically evaluate the R-barricade. The evaluation results show that the design effectively improves the driver’s attention to the barricade and effectively extends the gaze time, significantly improves the reaction time, and effectively improves the safety of the barricade. This study provides new perspectives for evaluating and improving traffic safety measures during highway emergency repairs and contributes scientific support to the advancement of interactive transport systems and road safety management.

Graph neural networks (GNN) demonstrate excellent performance on many graph-based tasks; however, they also impose a heavy computational burden when trained on a large-scale graph. Although various sampling methods have been proposed to speed up training GNN by shrinking the scale of the graph during training, they become unavailable if we need to perform sampling before training. In this paper, we quantify the importance of every edge for training in the graph with the extra information they convey in addition to the node features, as inspired by a manifold learning algorithm called diffusion map. Based on this calculation, we propose Graph Diffusion Sampling (GDS), a simple but effective sampling method for shrinking the size of the edge set before training. GDS prefers to sample edges with high importance, and edges dropped by GDS will never be used in the training procedure. We empirically show that GDS preserves the edges crucial for training in a variety of models (GCN, GraphSAGE, GAT, and JKNet). Compared to training on the full graph, GDS can guarantee the performance of the model while only samples a small fraction of the edges.

To capture higher-order structural features, most GNN-based algorithms learn node representations incorporating k-hop neighbors' information. Due to the high time complexity of querying k-hop neighbors, most graph algorithms cannot be deployed in a giant dense temporal network to execute millisecond-level inference. This problem dramatically limits the potential of applying graph algorithms in certain areas, especially financial fraud detection. Therefore, we propose Asynchronous Propagation Attention Network, an asynchronous continuous time dynamic graph algorithm for real-time temporal graph embedding. Traditional graph models usually execute two serial operations: first graph querying and then model inference. Different from previous graph algorithms, we decouple model inference and graph computation to alleviate the damage of the heavy graph query operation to the speed of model inference. Extensive experiments demonstrate that the proposed method can achieve competitive performance while greatly improving the inference speed. The source code is published at a Github repository.

Practical applications of microaerial vehicle face significant challenges including imprecise localization, limited on-board energy, and motion uncertainty. This paper focuses on the latter two issues. The core of proposed energy-optimal path planning algorithm is an energy consumption model deriving from real measurements of a specific quadrotor and utilizing a 2D Gaussian distribution function to simulate the uncertainty of random drift. Based on these two models, we formulate the optimal path traversing the 3D map with minimum energy consumption using a heuristic ant colony optimization. Multiple sets of contrast experiments demonstrate the effectiveness and efficiency of the proposed algorithm.
