Specific energy, resistance to drilling and alteration index are the indices that apply Rate of Penetration (ROP) and operational variables (weight on bit and rotary speed) to quantify the rock hardness.
Considering requirements specially for industrial purposes, system performances related to cost, weight, operational time, and system endurance & maintainability of the robot have to be specially pursued.
US diplomats recognised his overarching influence, describing him in cables published by WikiLeaks as "the rare Libyan official who embodies a combination of intellectual acumen, operational ability and political weight".
Now I was attempting to shape and implement a vision, build a strong staff culture among a new team, and deal with an immense weight of operational detail, including a multi-million pound building project.
A graduate of Michigan State University now in his early 60s, Mr. Koussa "is the rare Libyan official who embodies a combination of intellectual acumen, operational ability and political weight," said a May 2009 cable from the American Embassy in Tripoli.
However, as the CPU time is more important in operational problems, the considered weight is greater.
Thus, the operational definition of critical weight cannot be used interchangeably between different species.
The windings, located at flat slots, have short ends which therefore adds further improvements on the efficiency, power-to-weight ratio, operational performance and cost of active material.
While the other parameters are often uncontrollable, mud pressure (also referred to as mud density or mud weight) is an operational measure necessary to maintain stability.
