Accurate deformation prediction is crucial for ensuring the safety and longevity of bridges. However, complex fluctuations pose a challenge to achieving this goal. To improve accuracy, bridge method based on bidirectional gated recurrent unit (BiGRU) neural network error correction proposed. Firstly, BiGRU model employed predict data, which aims enhance modeling capability GRU time-series data through its structure. Then, extract valuable information concealed in error, transformer...

Graph Neural Architecture Search (GNAS) facilitates the automatic design of Networks (GNNs) tailored to specific downstream graph learning tasks. However, existing GNAS approaches often require manual adaptation new search spaces, necessitating substantial code optimization and domain-specific knowledge. To address this challenge, we present LLM4GNAS, a toolkit for that leverages generative capabilities Large Language Models (LLMs). LLM4GNAS includes an algorithm library neural architecture...

Graph neural networks (GNNs) are popularly used to analyze non-Euclidean graph data. Despite their successes, the design of requires heavy manual work and rich domain knowledge.

The introduction of cantilever-based fiber-optic microphones (FOMs) has proven to be effective in acoustic sensing. Further improvements cantilevers face two key constraints: the challenge achieving minimal sizes with sufficient reflective area and trade-off between sensitivity response bandwidth. Herein, we present a geometry optimization framework for FOM that addresses this issue. Employing drumstick-shaped housed within Fabry–Perot (F–P) interferometric structure, showcase heightened...

Abstract Free surface-assisted TBM disc cutter for rock breaking is an important direction the optimizing of structure. To study influence free surface on excavation, surfaces limited-width opening and unlimited-width were presented, six different combinations proposed. The penetration tests sandstone with carried out. results showed that mass adjacent to fell off after sample fracture. caused close broke. Under combinations, auxiliary effect was not obvious when depth shallow, failure...

Abstract Autonomous long‐duration aerostats (LDA) are one of the most popular research directions high‐altitude platforms (HAPS) in recent years. Solar photovoltaic (PV) array is energy source autonomous aerostat, whose power generation predicting accuracy and speed affect subsequent flight control strategy.

In spectral scene simulation applications, it is necessary to recognize and detect desert satellite images containing water. However, previous network models such as AlexNet, VggNet, GoogleNet have gradually fallen behind the trend of times. Compared with latest models, they not only slow training speeds but also do achieve high accuracy. Therefore, this study adopts a series solve problem compare analyze results.

A novel scheme that uses the SPICE (Simulation Program with Integrated Circuit Emphasis) simulation program as a behavioral modeling language in designing system of electronic circuit experiment is presented. In proposed method, SPICE, being redeveloped by transformation and expansion, used for simulating model imbedded multimedia interface DLL (dynamic link libraries) files, which succeeds solving integration technology technology. paper, an application example also given. Test results show...

Abstract Stratospheric airships are long‐endurance flight platforms that utilize renewable energy systems. The solar array in these systems cannot generate electricity at night; only an storage battery pack can be used to power the entire system. Therefore, accurate modeling and estimation of output characteristics operating conditions packs have become focus current research. During actual airship, uneven temperature distribution causes changes differences cell voltage packs. To address...

Three-port converter (TPC) with non-regulated bus cannot meet the voltage stability demands of high-altitude platforms (HAPs) during daytime operations. In contrast, full-regulated TPC is complex in topology and inferior power density, although it can maintain across whole day Therefore, semi-regulated TPCs are more suitable for this scenario, which not only operations, but also have simple topology. However, conventional structure converts twice, leading to lower efficiency density. order...
