The efficiency of the application a new technology for fir-tree slots treatment in turbine discs based on combination pre-slotting operations «house» by hydro-abrasive (HAT) and final broaching herringbone CNC machine comparison with milling, deep grinding EDM-ing methods is viewed. Problems arising within manufacturing operating broaches often cause down-time both types: main tool production. ...

Exponential growth in number of users with diverse data rate requirements has lead to the heterogeneity traditional cellular networks. To support massive users, nonorthogonal multiple access (NOMA) emerged as a promising solution achieve increased connections and higher spectral gains compared orthogonal (OMA). However, studies show that weak (WU) strong (SU) served using NOMA (referred NOMA-gr...
