The finishing mechanism in abrasive flow machining can be regarded as erosive wear, where the machining action is achieved by the micro-cutting or micro-ploughing generated by the collision between abrasive particles and the workpiece surface.
Over half of the world''s population depends on rice for its calorie supply, although it consumes the highest amount of water compared to other major crops. To minimize this excess water usage, alternate wetting and drying (AWD) irrigation practice is considered as an efficient technique in which soil intermittently dried during the growing period of rice by maintaining yield compared to a ...
The history of science is the study of the development of science, including both the natural and social sciences (the history of the arts and humanities is termed history of scholarship).Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real-world phenomena.
Soil erosion induced by rainfall under prevailing conditions is a prominent problem to farmers in tropical sloping lands of Northeast Vietnam. This study evaluates possibility of predicting erosion status by machine learning models, including fuzzy k-nearest neighbor (FKNN), artificial neural network (ANN), support vector machine (SVM), least squares support vector machine (LSSVM), and ...
May 07, 2021· I have a long cylindrical shell with dimensions length = 20 m, radius = 2 m and thickness = 3 cm. I want to do a geometric non-linear buckling analysis in Abaqus with no imperfections included.
Apr 29, 2021· The shear failure mechanism of polycrystalline gas hydrates is critical for understanding marine geohazards related to gas hydrates under a changing climate and for safe gas recovery from gas hydrate reservoirs. Since current experimental techniques cannot resolve the mechanism on a spatial and temporal nanoscale, molecular simulations can assist with proposing and substantiating …

Multibeam echosounders are widely used for 3D bathymetric mapping, and increasingly for water column studies. However, they rapidly collect huge volumes of data, which poses a challenge for water column data processing that is often still manual and time-consuming, or affected by low efficiency and high false detection rates if automated. This research describes a comprehensive and ...

Along with the growth of big data, machine learning became the preferred technique for searching, analyzing and der iving insights from such data. We observed the complementary nature of bot tom-up (machine learning-driven) and top-down (semantic, knowledge …
A laboratory investigation of abrasive waterjet cutting of wheat straws was conducted. The work was aimed at a systematic characterization of the abrasive waterjet cutting capability of wheat straws, as a potential alternative to cutting discs currently adopted in no-till drills and planters for crop residue management. A two level 2IV7−3 fractional factorial design was applied to ...
