A theoretical and experimental investigation of the effect of pressure on Mechanical Specific Energy and Cutting Efficiency was performed. The bottomhole expansion theory of Warren and Smith was verified and it was shown through finite element analysis that permeability of the formation restricts the use of this theory in many cases. Single cutter experimentations under pressure showed that the...

Due to the nonlinear nature of the Bang-Bang phase-locked loops (BBPLLs), its transient analysis is very difficult. In this paper, new equations are proposed for expression of transient behavior of the second order BBPLLs to phase step input. This approach gives new insights into the transient behavior of BBPLLs. Approximating transient response to reasonable specific waveform the loop tran...
