Existing systems are limited to specific regions, lacking generalizability to unseen areas. This paper presents a novel taxi demand prediction system, harnessing the strengths of multiview graph neural networks to capture spatial-temporal dependencies and patterns in urban environments. Additionally, the proposed system CROSS-Net employs a spatially transferable approach, enabling it to train a model that can be deployed to previously unseen regions. To achieve this, the framework incorporates the power of a Variational Autoencoder to disentangle the input features into region-specific and region-agnostic components. The region-agnostic features facilitate cross-region taxi demand predictions, allowing the model to generalize well across different urban areas. Experimental results demonstrate the effectiveness of CROSS-Net in accurately forecasting taxi demand, even in previously unobserved regions, thus showcasing its potential for optimizing taxi services and improving transportation efficiency on a broader scale.Wed, 01 Apr 2026 00:00:00

require distributed phased-array antennas formed by thousands of satellites flying in precise coordination. Evaluating control algorithms for such large formations demands simulation tools that combine high-fidelity orbital mechanics with scalable parallel execution, but existing frameworks do not satisfy both requirements. This paper presents a distributed simulation framework for large-scale satellite formation flying. The framework decomposes simulation into independent modules for orbital propagation, electromagnetic force computation, and control algorithms, connected through ROS2 publish-subscribe messaging. A snapshot-based synchronization mechanism coordinates modules at fixed intervals while orbital propagators advance with adaptive timesteps internally. We implement orbital mechanics using Orekit with perturbation models including non-spherical Earth gravity, atmospheric drag, solar radiation pressure, and third-body effects. Evaluation on formations of up to 10,000 satellites demonstrates a 7.6× speedup with 16 parallel nodes under full perturbation models, and sub-millimeter position errors below 0.4 mm RMS over 7-day two-body simulations used for numerical validation. The modular architecture allows researchers to integrate new control algorithms without modifying existing modules.Tue, 01 Apr 2025 00:00:00 GMTinternational_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/Rizk Hamada, 内山 彰, 山口 弘純, 森岡 澄夫, 稲川 貴大Tue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/Heetae Jin, Akira UchiyamaTue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/天野辰哉, 廣森聡仁, 山口弘純, 森岡澄夫Tue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/矢野敦大, 天野辰哉, 山口弘純Tue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/丸山結, 辻凌平, 内山彰, Hamada Rizk, 山口弘純, 森岡澄夫, 稲川貴大Tue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/Yanlong Ouyang (The University of Osaka), Shin Mizutani (NTT, Inc.), Yasue Kishino (NTT, Inc. / The University of Osaka), Hirozumi Yamaguchi (The University of Osaka)Tue, 01 Apr 2025 00:00:00 GMTdomestic_confhttps://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/https://mc.net.ist.osaka-u.ac.jp/ja/publications/year/2025/山口弘純, 峰野博史, 安本慶一, 東野輝夫Tue, 01 Apr 2025 00:00:00 GMTdomestic_conf
