To better understand the elevated temperature flow behaviors of 30Si2MnCrMoVE low-alloy ultra-high strength steel, hot compressive deformation tests were performed at a wide range forming temperatures (1123–1423 K) and strain rates (0.01–1s−1). The constitutive equations material established through physical-based modified Zerilli-Armstrong (ZA) phenomenological Arrhenius-type models, along with optimized ZA model compensation constructed based on model. Suitability these models evaluated by...
Magnetic sense, or termed magnetoreception, has evolved in a broad range of taxa within the animal kingdom to facilitate orientation and navigation. MagRs, highly conserved A-type iron-sulfur proteins, are widely distributed across all phyla play essential roles both magnetoreception cluster biogenesis. However, evolutionary origins functional diversification MagRs from their prokaryotic ancestor remain unclear. In this study, MagR sequences 131 species, ranging bacteria humans, were...
A novel recrystallization and partial melting process combined radial forging was proposed to prepare long axial 2A50 aluminum alloy semi-solid billets. Microstructure characteristics of the forged isothermal treated samples were investigated. Results demonstrate that initial elongated grains (fibrous structure) low angle grain boundaries substituted by spherical equiaxed high when sample heated at 585 °C for 10 min. Deformed textures remarkably weaken after treatment. The average size shape...
Based on the engineering context of prefabricated underground station structures, this paper proposed a novel diaphragm wall–beam joint based post-poured ultra-high-performance concrete (UHPC) and non-contact lap-spliced steel bars. This research study designed conducted full-scale experiment joints. The failure modes, bearing capacity, overall stiffness, crack resistance performance, force transmission mechanism new were investigated. Additionally, three-dimensional finite element model...
The 7075 aluminum alloy semi-solid billet is prepared using the extrusion isothermal treatment (EASSIT) process. These findings indicate that as time increases, there a noticeable increase in both average grain size (AGS) and shape factor (SF). relationship between AGS, SF, temperature complex due to influence of refinement mechanisms. HV0.2 samples decreased with temperature, which may be related liquid-phase composition AGS; Cu Si show obvious segregation at boundaries within...
Fraud behavior poses a severe threat to e-commerce platforms and anti-fraud systems have become indispensable infrastructure of these platforms. Recently, there been large number fraud detection models proposed monitor online purchasing transactions extract hidden patterns. Thanks models, we observed significant reduction committed frauds in the last several years. However, an increasing malicious sellers on platforms, according our recent statistics, who purposely circumvent by transferring...
This study proposes a new type of tri-screw pump, which has 1:2:3 ratio the active diameter screw, pitch circle, and top screw. Fixed width correction method driven screw is also proposed to avoid wear tooth top. The mathematical model screws established. To arc, several transition patterns are proposed, curve in form circular arc deduced. designed grinded, pump assembled. hydraulic test bench tested using overflow valve perform pressure loading 3–5 MPa on outlet pump. flow rate tested,...
A novel method called friction stir rivet welding (FSRW) is proposed to combine mechanical interlocking and metallurgical joining, expected improve such properties eliminate the keyhole defects in traditional spot welded (FSSW) joints. The FSRWed joint forms joining between upper lower sheets, while surrounding plasticized materials. spindle force, bonding mode, failure mode of three joints are comparatively investigated clarify strengthening mechanism FSRW method. Results indicate that...
Bone milling is one of the most common operations in various kinds orthopedical surgeries, such as laminectomy surgery. For safety issue and efficacy, it very important to recognize states operation. In this paper, an approach bone proposed, which identify cortical tissue layer cancellous layer. Hilbert-Huang Transform (HHT) based on Empirical Mode Decomposition (EMD) used analysis extract features interactive force The instantaneous amplitude Intrinsic Functions (IMF) are combined by means...
This letter presents a semisupervised feature extraction based on collaborative label propagation (SSCLP) for hyperspectral images (HSIs). SSCLP first proposes novel method to predict the labels of unlabeled data that are termed weak labels. Then, combines known and predicted construct two new discriminative matrices. Finally, matrices utilized find an optimal transformation matrix achieve HSIs. The proposed not only preserves compactness intraclass separability interclass but also explores...
