In aerodynamic optimization, global optimization methods such as genetic algorithms are preferred in many cases because of their advantage on reaching optimum. However, for complex problems which large number design variables needed, the computational cost becomes prohibitive, and thus original strategies required. To address this need, data dimensionality reduction method is combined with methods, forming a new system, aiming to improve efficiency conventional optimization. The system...

Accurately capturing the full-range response of structures is crucial in structural health monitoring (SHM) for ensuring safety and operational integrity. However, limited sensor deployment due to cost, accessibility, or scale often hinders comprehensive monitoring. This paper presents a novel data fusion framework utilizing diffusion models reconstruct from sparse heterogeneous measurements. We incorporate Diffusion Posterior Sampling (DPS) into reconstruction framework, using measurements...

Point cloud salient object detection has attracted the attention of researchers in recent years. Since existing works do not fully utilize geometry context 3D objects, blurry boundaries are generated when segmenting objects with complex backgrounds. In this paper, we propose a geometry-aware network that explicitly clusters points into superpoints to enhance geometric thereby complete clear boundaries. Specifically, first simple yet effective superpoint partition module cluster superpoints....

Great efforts have been devoted to improving the performance of scene classification. However, it is still a challenging task because complex background and diverse objects in images. To address this issue, multiple resolution block feature (MRBF) proposed for remote-sensing It unified effective representation, consisting completed double cross pattern (CDCP) combined with fisher vectors (FV). Specifically, order capture more robust richer information, descriptor devised based on CDCP. After...

The positioning accuracy UAV clusters is core basis application, this paper proposes a cluster information geometry fusion method based on low‐orbit satellite system, which uses geometric relationship between to transform constellation navigation each into an probability model, reducing influence system time asynchrony,...

Children's education and entertainment products play a crucial role in children's growth by integrating knowledge transfer, skill development, enjoyable experiences. As family concepts continue to evolve, parents' demands for these have become increasingly diverse. This study focuses on children under 12 their parents, aiming explore the settings understand core needs expectations of both parents when using products. The research employs qualitative quantitative methods, including user...

Unmanned aerial vehicles (UAVs) combining with mobile edge computing (MEC) networks have promoted the application of Internet Things (IoT) devices, providing enhanced coverage flexible services. But energy consumption data processing is still a shortage in UAV-assisted MEC architecture. Motivated by that, we propose dynamic network and formulate problem jointly optimize association strategies, UAV trajectory, offloading, resource distribution for minimizing total consumption. To deal this...
