To improve the accuracy of fault diagnosis of bearing, the improved particle swarm optimization variational mode decomposition (VMD) and support vector machine (SVM) models are proposed.Aiming at the convergence effect of particle swarm optimization (PSO), dynamic inertia weight, and gradient information are Mullein introduced to improve PSO (IPSO)
In Europe, regulations contain guidance to maintain high standards of animal welfare.In many parts of the world, large buyers for supermarkets or restaurants are the main enforcers of basic animal welfare standards.They can have considerable influence on improving standards on large commercial farms.Research Notebooks clearly shows that straw is on
With the rapid development of aerospace, high-speed train, and automotive industries, the demand for the measurement of high-precision specular components is increasing.The acquisition of high-precision three-dimensional (3D) data is conducive to improving the performance of and extending the service life of these components.However, the existing 3
Populations of the big-headed turtle Platysternon megacephalum are declining at unprecedented rates across most of its distribution in Southeast Asia owing to unsustainable harvest for pet, food, and Chinese medicine markets.Research on Asian freshwater turtles becomes more challenging as populations decline and basic ecological information is need
Determining the sub-cellular localization of a protein within a cell is often an essential step towards understanding its function.In Caenorhabditis elegans, the relatively large size of the body wall muscle cells and the exquisite organization of their sarcomeres offer an opportunity to identify the precise position of proteins within cell substru
