To solve the problem that lack of reference for hull plate division leads to difficulty and low efficiency curved forming, forming evaluation complex plates is researched. Considering characteristics in process, model based on grey relational analysis established. The process designed. influence law parameters are revealed. weight coefficients different influencing factors quantified. Taking re...

Abstract Gout has become a global problem, antiuric acid formula (AAF) is clinical prescription highly effective in reducing uric levels. In order to find its quality control standards and contribute the treatment of gout future, we adopted high-performance liquid chromatography orbitrap chromatography–mass spectrometry establish fingerprints 13 batches AAF. The different AAF were tested activi...

Most of the extant studies in social recommender system are based on explicit relationships, while potential implicit relationships heterogeneous networks remains largely unexplored. This study proposes a new approach to designing by employing grey relational analysis networks. It starts with establishment through user-item bipartite graph, user network graph and user-attribute graph; then uses...

This study investigated the optimization of computer numerical control (CNC) boring operation parameters for aluminum alloy 6061T6 using the grey relational analysis (GRA) method. Nine experimental runs based on an orthogonal array of Taguchi method were performed. The surface properties of roughness average and roughness maximum as well as the roundness were selected as the quality targets. An...
