The effective surface area, A, of the evaporator two-phase region was found to vary quadratically with refrigerant mass flow rate, probably as a result of changes in liquid level or droplets carried into the superheating section, according to:
In accordance with the Guidelines for Reporting Reliability and Agreement Studies (GRRAS), inter-rater reliability was assessed using the unweighted, linearly weighted and quadratically weighted k (QWK) statistic, as well as the intraclass correlation coefficient (ICC).
The Gurobi Optimizer is a state-of-the-art solver for linear programming (LP), quadratic programming (QP), quadratically constrained programming (QCP), mixed-integer linear programming (MILP), mixed-integer quadratic programming (MIQP), and mixed-integer quadratically constrained programming (MIQCP).
This freedom is due to the fact that the parameters enter the equation quadratically, thus avoiding negative variance estimates, as pointed out by Enders (2009).
A prominent calibration challenge for a model accounting for correlations is that the number of pairs grows quadratically with the number of countries of interests.
a large pool of assets' returns, a basic mean--variance analysis requires estimation of a quadratically increasing number of expected returns, standard deviations, and correlation coefficients) To overcome the difficulty of having to estimate the statistics using long historical data to attain low standard deviations, a linear factor model that relates the returns of the portfolio to a finite number of factors can be introduced.
However, as the instances become more complex, the number of clauses added by the pairwise encoding increases quadratically.
Zhang, an assistant professor of bioengineering at Rice University, said that in terms of specificity, our research suggests that we can do quadratically better, meaning that whatever the best level of specificity, our best will be that number squared.
