We present DeepSeek-V3, a strong Mixture-of-Experts (MoE) language model with 671B total parameters 37B activated for each token. To achieve efficient inference and cost-effective training, DeepSeek-V3 adopts Multi-head Latent Attention (MLA) DeepSeekMoE architectures, which were thoroughly validated in DeepSeek-V2. Furthermore, pioneers an auxiliary-loss-free strategy load balancing sets multi-token prediction training objective stronger performance. pre-train on 14.8 trillion diverse...
The alternating current field measurement (ACFM) technique has been widely used in the defect detection of metal structures. However, identification and reconstruction defects depend on human experience or simple empirical formulas, which leads to misjudgment large quantization errors. In this article, we propose an end-to-end physics-informed neural network for 3-D reconstruction. high-precision automatic system with a specially designed probe is established detect any direction. faster...
Alternating current field measurement (ACFM) technique has been widely used in defect inspection of underwater metal structures. However, due to the high cost inspection, it is difficult carry out nondestructive testing (NDT) regularly obtain health status key nodes And quantification defects depends on simple empirical formula, which leads large quantization error. In this paper, a flexible ACFM magnetic sensor array for in-situ structural cracks proposed. A probe based manufactured and can...
Aircraft structures are prone to fatigue cracks under various loads, which seriously threaten the safety performance of aircraft. Therefore, it is particularly important carry out long-term structural health monitoring (SHM) for key nodes aircraft structures. This article attempts apply alternating current field measurement (ACFM) technique SHM field. In this article, based on principle ACFM, a uniform (UACFM) proposed. Through simulation analysis, change law corresponding characteristic...
Lift-off is a challenging issue in alternating current field measurement (ACFM) technique. The spurious signals caused by lift-off variations are similar to the response of defects, resulting defect misjudgment. In this paper, point intersection (LOI) feature discovered for first time from raw ACFM elimination variations. A theoretical model established analyze effect on characteristic ACFM. 3D finite element built excitation frequency LOI. probe and testing system established, validation...
Alternating current field measurement (ACFM) has been widely used to detect and evaluate metal surface cracks. However, the lift-off caused by various attachments significantly affects accuracy of crack size assessment. In this article, a simple method is proposed cracks without limitation lift-off. The theoretical models ACFM effect are developed. influence on magnetic response signals studied with aid finite-element (FEM). test system set up, experiments carried out different dimensions at...
Abstract Nonferromagnetic pipes are widely used in power plants such as fluid transportation and heat exchanger devices. Due to the severity of environments, including corrosion, high temperature, etc, they subject surface arbitrary-angle cracks. In view this background, paper proposed a rotating alternating current field measurement (RACFM) testing system for cracks on nonferromagnetic pipes. The RACFM pipe detection model is established unidirectional excitation coil orthogonal coils...
In today's fast-paced world, the growing demand to quickly generate comprehensive and accurate Wikipedia documents for emerging events is both crucial challenging. However, previous efforts in generation have often fallen short of meeting real-world requirements. Some approaches focus solely on generating segments a complete document, while others overlook importance faithfulness or fail consider influence pre-training corpus. this paper, we simulate scenario where structured full-length are...
Numerical analysis of the flow-field in a contra-rotating fan has been performed by using CFD method. The LES technique is applied to simulate 3D unsteady whole fan. Several monitoring faces are specified between two impellers. Three points, which respectively near hub, casing and middle flow passage, on each other faces. FW-H model introduced aerodynamic noise. distribution characteristics noise show that broadband mainly occurs at within impellers, while away from rotating blades, fades....
Alternating current field measurement (ACFM) technique is an emerging non-destructive testing method for detecting cracks in conductive material.
