We consider the problem of recovering the graph structure of a “hub-networked” Ising model given i.i.d. samples, under high-dimensional settings, where number of nodes p could be potentially larger than the number of samples n. By a “hub-networked” graph, we mean a graph with a few “hub nodes” with very large degrees. State of the art estimators for Ising models have a sample complexity that sc...

This study analyzed the fundamental geometric and kinematic characteristics of the swing hub path of the golf shot for four diverse subjects. In addition, the role of the hub path geometry in transferring the kinetic quantities from the golfer to the club were investigated. The hub path was found to have a complex geometry with significantly changing radii, and a constantly moving center-of-cur...

During tunneling processes, disc cutters of a tunnel boring machine (TBM) usually need to be frequently and unexpectedly replaced. Regular inspections are needed check cutters’ status, which significantly reduces the work efficiency increases cost. This paper proposes new prediction model based on TBM operational parameters geological conditions that determines whether cutter replacement is nee...
