In this paper, an intelligent damage detection approach is proposed for steel-concrete composite beams based on deep learning and wavelet analysis.To demonstrate the feasibility of approach, first, following guidelines provided by relevant standards, are designed, six different incidents established.Second, a steel ball used free-fall excitation surface low-temperature-sensitive quasi-distributed long-gauge fiber Bragg grating (FBG) strain sensor to obtain signals with types.To reduce effect...
Laser annealing has attracted significant attention for ohmic contacts of the 4H-SiC substrate, especially Ni-based contact. In this study, a metallic capping layer (Ti, Nb, Mo, W, or Ag) was placed on top Ni as absorption 355 nm laser, and effect laser thermal budget investigated. The temperature fields (30 nm)/Ni (70 nm)/4H-SiC (100 μm) were simulated numerically using finite element method. results demonstrated that can be affected by main properties layer, including absorptivity,...
A difficult problem in mobile internet security is how to prevent key leakage when using traditional symmetric cryptographic algorithms devices, because devices face with White-Box attacking environment so the program running on can be fully controlled by attackers. In other hand, memory space relatively limited compared most computers, an anti-key-leakage tiny needed for which have high degree of and efficiency meanwhile. This paper puts forward two CLEFIA implementations according special...
Purpose Hexahedral meshing is one of the most important steps in performing an accurate simulation using finite element analysis (FEA). However, current hexahedral method industry a nonautomatic and inefficient method, i.e. manually decomposing model into suitable blocks obtaining mesh from these by mapping or sweeping algorithms. The purpose this paper to propose almost automatic decomposition algorithm based on 3D frame field features replace traditional time-consuming laborious manual...
Chemical molecular structures are a direct and convenient means of expressing chemical knowledge, playing vital role in academic communication. In chemistry, hand drawing is common task for students researchers. If we can convert hand-drawn into machine-readable formats, like SMILES encoding, computers efficiently process analyze these structures, significantly enhancing the efficiency research. Furthermore, with progress educational technology, automated grading gaining popularity. When...
Automated Guided Vehicle (AGV), serving as an important tool for wide industrial applications, suffers many control problems coupling impacts of rotation and shift moving. We present a decoupling controller to improve the kinematic performance AGV in paradigm PID control. For adaptive tuning PID, heuristic optimization strategy, named Beetle Antennae Search (BAS), is employed generate proper adjustment parameter estimation. Finally, effectiveness algorithm proved by simulation experimental results.
Under long-term load, the creep deformation of concrete materials has a serious impact on structural safety hydraulic structures, especially under action ultra-high stress levels, will undergo nonlinear creep, which is extremely easy to cause damage. In this study, uniaxial test specimens was used establish damage index based wave velocity value ultrasonic flaw detection, and degree curve specimen were obtained. The ideal elastic element, Kelvin body, viscoplastic element are connected in...
Abstract Chemical molecule structures are important in academic communication because they allow for a more direct and convenient representation of chemical knowledge. Hand-drawn molecular common task chemistry students researchers. If hand-drawn structures, such as SMILES codes, could be converted into machine-readable data forms. Computers would able to process analyze these greatly increasing the efficiency research. Furthermore, with advancement information technology education,...
Abstract Pedestrian detection plays a critical role in computer vision applications, but the performance of existing algorithms utilizing visible images is inadequate when confronted with poor lighting conditions. Conversely, infrared deliver superior outcomes low-light environments. Based on this issue, study proposes Double-EfficientDet-Improved (DEDI), dual-stream model that integrates both and imagery by enhancing EfficientDet network structure. Firstly, shuffle module integrated into...

The paper has ability automatically efficiently obtain high-quality...
When the large-volume concrete structure of hydraulic engineering encounters a sudden drop in ambient temperature, instantaneous temperature stress can easily cause surface to crack. Taking pier as an example, ANSYS software is used this paper simulate influence process rainstorm or flood release, and on tensile structure. At same time, variation range produced by different linear expansion coefficients, drops, thickness calculated. It found that case gate has little effect change stress,...
Reducing the length of concrete pouring blocks is one most important measures for temperature control and crack prevention mass concrete, but there little exploration specific relationship between drop blocks. In this paper, finite element model different established block in strong restraint area dam. The maximum base difference that can be withstood by zone with lengths obtained, which provide a reference index during process.
