Mesh screens have been proven effective in reducing noise levels in various applications. Studies have shown that mesh screens can help in noise reduction by perturbing the initial shear layer of supersonic jets, leading to effective suppression of jet noise . Additionally, the use of a grid screen as a passive method of inlet flow conditioning has been experimentally studied, showing a reduction in noise levels induced by inlet flow distortion, even with a slight weakening of the fan's aerodynamic performance due to flow resistance . Furthermore, a vibrating mesh screen has been proposed as an alternative to static mesh screens in dust scrubbers, demonstrating improved dust collection efficiency and reduced clogging issues through enhanced dust particle collision opportunities and increased mesh wetted area . These findings collectively highlight the effectiveness of mesh screens in reducing noise levels in various industrial settings.

What are the disadvantages of mesh CNNs?5 answersMesh CNNs have shown great promise in processing 3D data, but they do come with certain limitations. One key disadvantage is that traditional MeshCNN implementations can only operate on the edges of triangular meshes, which may be restrictive for applications focusing on other primitives of the mesh. Additionally, irregular structures of meshes pose challenges in building hierarchical structures and aggregating local geometric information efficiently, which is crucial for deep neural mesh processing networks. Furthermore, the non-uniform and irregular nature of mesh data makes learning with Deep Neural Networks complex, leading to issues in capturing both geodesic and geometric characteristics effectively. Addressing these challenges, new approaches like self-parameterization-based multi-resolution convolution networks have been proposed to enhance mesh dense predictions by overcoming downsampling, upsampling, and convolution operation difficulties.
How does the mesh face algorithm improve the performance of face recognition in images?4 answersThe mesh face algorithm improves the performance of face recognition in images by generating a 3D regular mesh of each input face image, converting the meshes to voxels to create an occupancy grid, and training 3D ShapeNets for recognition. This approach eliminates the need for face representation methods as a proxy step and allows for the recognition of faces covering the full 3D shape. The use of 3D ShapeNets in face recognition is a novel contribution, and the experimental results show significant improvement over state-of-the-art performance on various datasets. Additionally, the mesh-based optimization regime and perturbation of the low-dimensional coefficient space based on 3D Morphable Model enhance the transferability and visual quality of adversarial textured 3D meshes, which can be used to evaluate the robustness of commercial face recognition systems.
How does fog collector system using mesh?4 answersFog collector systems using mesh have been studied extensively in recent research. Metal meshes have shown promise in capturing both natural and industrial fogs, with water collection efficiency depending on mesh wettability, geometry, and orientation with respect to the fog-laden wind. A novel harp structure with cylindrical monofilaments has been developed, which significantly increases fog harvesting efficiency compared to conventional Raschel mesh. The efficiency of conventional meshes, such as plain-woven, plain-knitted, and 3-D spacer structures, has been investigated, with factors such as fiber diameter, fiber spacing, and fiber arrangement affecting collection efficiency. Another proposed fog collector design consists of a hexagonal tubular structure supporting a membrane or mesh for water collection, with gravity guiding the collected water to trays for storage or diversion. Additionally, fog collectors with nanochannels and macrostripes have been developed, enabling spontaneous droplet removal and preventing re-entrainment, resulting in a 50% enhancement in fog harvesting performance compared to conventional mesh-like fog collectors.
Does the mesh size of agricultural lime affect the effectiveness of the lime?4 answersThe mesh size of agricultural lime does affect its effectiveness. Finer materials react faster with soil to increase pH, while coarser materials may take longer to have an effect. Particle size is a physical factor that can influence the reactivity of liming materials. In an experiment on sulfidic acid sulfate soils, lime particle sizes below 1 mm were found to be effective in alkaline soils, while a particle size below 0.5 mm was required in acidic soils. The ideal agricultural lime is a ground dolomite or dolomitic limestone with a particle size of 100% <2mm, 60%<400μm, and up to 50% <150μm. The effectiveness of limestone in neutralizing soil acidity is measured by its calcium carbonate equivalent (CCE), which is influenced by particle size.
How does a wire mesh create turbulent flow?5 answersA wire mesh creates turbulent flow by generating supersonic, MHD turbulence. In laboratory experiments, magnetized supersonic flows are driven through a wire mesh to investigate its ability to generate turbulence. The flow analysis includes statistical measures such as power spectra and probability distribution functions of the density. The initially hypersonic planar shock through the wire mesh leads to downstream turbulent conditions. However, the resultant turbulence is marginally supersonic to transonic and highly anisotropic in structure. The wire mesh configuration with different dimensions and spacings of vertical bars in each layer creates through holes that contribute to the generation of turbulence. The mesh surface roughness also affects the turbulence characteristics, such as surface shear stress, mean velocity, turbulence intensities, and Reynolds shear stress. Additionally, concentrated regions of intense kinetic energy can be used to initialize the flow and study the development of turbulence.
