Shaft sinking is one of the main parts in underground mine planning. Shaft has various applications in underground mines e.g. minerals exiting flow, gases entrance or exit way, stope developments for exploitation etc. Considering that this section requires an abundance of expenses, management always following the election is the way that both terms have the technical considerations, economic co...

Inefficiency occurs with ex post fines, when small firms declare bankruptcy and escape their liabili...

Comparisons are made between the turning points of the two cycles, and formal tests for cyclical asymmetry (in terms of both "steepness" and "deepness") are conducted. The turning-point comparisons reinforce ...

As people have come to expect more from Wi-Fi of late, there has been concurrent interest in blanketing underground transit systems with wireless coverage, from Transpo...
