Uncertainty Estimation of Connected Vehicle Penetration Rate

Transportation Science, 2023
Knowledge of the connected vehicle (CV) penetration rate is crucial for realizing numerous beneficial applications during the prolonged transition period to full CV deployment. A recent study described a novel single-source data penetration rate estimator (SSDPRE) for estimating the CV penetration rate solely from CV data.

Rates of Unemployment and Penetrating Trauma Are Correlated

Southern Medical Journal, 2003
Trauma surgeons have observed an increased rate of penetrating trauma during periods of increased unemployment.During a 10-year period, the rate of unemployment in a metropolitan area was compared with the rate of intentional penetrating trauma at two Level I trauma centers. The total number of trauma cases was recorded.

Rheology Design To Optimise Rate of Penetration

Proceedings of SPE/IADC Drilling Conference, 1996
Abstract A Bit Reynolds Number optimization algorithm has been developed in response to the field observation that this maximizes the rate of penetration regarding bit hydraulic effects. Discussion on the reasons for such behaviour are undertaken and some common drilling scenarios are presented for which Bit Reynolds ...

The Effect of Rheology on Rate of Penetration

SPE/IADC Drilling Conference, 1995
Abstract Field data have been collected and analyzed to 1) identify the characteristics of a drilling fluid that enhance rate of penetration, and 2) quantify the impact of particular fluid properties on rate of penetration. The information is being used to evaluate the economics of a fluid treatment program in order to deliver optimal ...
