Multimodal medical image fusion aims to integrate complementary information from different modalities of images. Deep learning methods, especially recent vision Transformers, have effectively improved performance. However, there are limitations for Transformers in fusion, such as lacks local feature extraction and cross-modal interaction, resulting insufficient multimodal integration. In addition, the computational cost is higher. To address these challenges, this work, we develop an...
The design of the flow field structure for bipolar plates significantly influences output performance proton exchange membrane fuel cells (PEMFCs). Adding baffles in channels can enhance transportation reactants and electrochemical PEMFCs. In this study, three types with different shapes sizes were designed. Computational fluid dynamics (CFD) models PEMFCs a symmetrical serpentine (SSFF), both without baffles, established using CFD method. Numerical simulations PEMFCs, performed by FLUENT...
Abstract The effects of surface elasticity and viscoelasticity as well tension on the deformation solids with liquid inclusions are investigated using a finite element (FE) method. Both stiffen inclusions. in elastic capillary number is replaced Young’s modulus to define second number. aspect ratio included liquids used indicate stiffening effect for both numbers. A smaller corresponds larger effect. In typical FE analysis, when either 1 applied strain 4%, decreases by 7.4% due 2.6%...
A systematic study on the fracture surface of brittle Mg-, Fe-, and Co-based metallic glasses under compressive loading is approached a mechanism proposed. Experimentally, glass samples are compressed into many small fragments, displaying an explosion feature. Therefore, energy equilibrium model employed to describe processes those glasses. Furthermore, some regular nanoscale steps, which were scarcely discovered, found mirror region their surfaces. It suggested that such steps associated...
It was found that stress displayed an oscillating pattern due to the discontinuous sliding process in samples under compressive loading on diamond Ti6Al4V lattice structure with shells. A simple model used for calculating relative density of proposed and evaluated. Moreover, theoretical models better precision were suggested estimate elastic modulus yield strength structures without considering Besides, a quantitative describe shell effect lattices validated be acceptable by comparing...
The significant effect of the strut angle on mechanical properties strut‐based lattice structures is systematically explored through experimental and numerical investigations. highest values elastic modulus yield strength, surpassing those observed in cubic lattices with same relative density, have been experimentally at 71.76°. A correlation among modulus, angles lattices, validated by tests, has identified developing a theoretical modelling conducting detailed finite element analysis....
Abstract The plasticity of Ti-based metallic glasses with different aspect ratios can be improved by introducing two semicircular notches on the edges samples, owing to interactions shear bands (SBs) under conventional compression tests. interaction SBs ascribed easy initiation around due large stress gradient, and consequent blocking effect propagation bands. Additionally, current findings provide a new way understand physical nature for plastic deformation behavior some brittle supply an...
The enhanced behavior of hydrogen embrittlement (HE) fracture for pre-strain hardening 2205 duplex stainless steel was investigated. Specimens with various degrees engineering strain were pre-charged by cathodic charging, and then immediately loaded up to facture under uniaxial tensile test. Results demonstrated that the susceptibility HE increased increasing level pre-deformation, manifested loss ductility transition from dimple quasi-cleavage morphology. Post-mortem microstructural...
In this investigation, analyses of pressure fluctuations during oil and gas pipeline operations are performed. The performed in a way to capture all the variables their magnitudes terms crack growth rate. It is found that spectra can be categorized into three main types: underload-dominant, mean load-dominant, overload-dominant spectra, depending on locations with respect compressor or pump station. underload spectra—typical at discharging sites—are most severe as these subjected highest...
