background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...

Numerous outcome measures can be used to characterize and compare the performance of alternative quality-control (QC) strategies. The performance measure traditionally used in the QC planning process is the probability of rejecting an analytical run when a critical out-of-control error condition exists. Another performance measure that naturally fits within the total allowable error paradigm is...

BACKGROUND Glucose meter analytical performance criteria required for safe and effective management of patients on tight glycemic control (TGC) are not currently defined. We used simulation modeling to relate glucose meter performance characteristics to insulin dosing errors during TGC. METHODS We used 29,920 glucose values from patients on TGC at 1 institution to represent the expected distr...

in order to compare the precision of predictions of nrc (2001) and cncps models, 17 holstein fresh cows were assigned in a randomized complete block design to a balanced diet with nrc (2001) and cncps software. the predicted dmi, energy allowable milk and protein allowable milk by both models were compared with observed values. the precision of the predictions of models was evaluated by calcula...

The aim of this paper was to present an optimized method in order to use maximum capacity of the photovoltaic panels. In this regard, we presented a method for the maximum power point tracking in the photovoltaic systems by using the neural networks and adaptive controller. In the proposed system, we estimated an error by using neural network. If this error is lower than the allowable systems e...

Quantum algorithms for the simulation of quantum systems described by a Hamiltonian provide an exponential improvement in speed over classical algorithms when one considers scaling of the complexity in terms of the dimension. However, one key drawback is that the scaling in terms of the allowable error, ε, is relatively poor. Here we provide a new quantum algorithm whose scaling with respect to...

CONTEXT Proficiency testing (PT) participants can interpret their results to detect errors even when their performance is acceptable according to the limits set by the PT provider. OBJECTIVE To determine which rules for interpreting PT data provide optimal performance for PT with 5 samples per event. DESIGN We used Monte Carlo computer simulation techniques to study the performance of sever...
