Compute the local maximum and minimum values and saddle points of the function f(x,y)=ey(y2−x2).Finding Local Extrema and Saddle Points of a Multi-Variable FunctionGiven a multivariable function of the form f(x,y), the critical points are those points (...
Although correlation between geographic range and occurrence frequency may account for some of this association, results from multivariable regression analysis suggest that the association between occurrence frequency and extinction risk is largely independent of geographic range. Within local assemblages, ...
(11) were determined using constrained gradient-based nonlinear multivariable optimization techniques available in MATLAB’s Optimization Toolbox [45]. Tables 3 and 4 (located in the appendix) presents a summary of the final fitted parameters for each individual foam specimen, and quality of the ...
46,47,48,49,50, the applications of ANN and MLR methods to predict and determine the mechanical interactions between concrete and steel bars, such as local bond stress (LBS), have not been covered. Therefore, in this study, we developed the use of an ANN algorithm in structural engineering...

using negative binomial regression. Monthly minimum temperature of 17.5–20.8 °C, an average temperature of 26.1–26.7 °C, a maximum temperature of 33.6–34.7 °C, rainfall between 11.4–12.7 cm, and increasing numbers of imported dengue cases were associated with the highest risk of dengue inc...
The high-symmetry atomic position at the center of a PE basin is at a local energy minimum. In contrast, MLM solids have multiple stable structures associated with several LPEM, separated by the associated local barriers, 𝐸𝑙El, that are low compared to the thermal energy 𝑘𝑇kT of...
(monoplane implant) with minimum two-centimeter distance to the surgical margin on the skin. The tubes were kept parallel to each other with an interspacing distance of 8–12 mm over the target area. In case of needed surgical reconstruction, interstitial tubes were implanted afterwards but ...
Covariates withp-value ≤ 0.2 at univariable analysis were entered into a multivariable model. Upper and lower 95% confidence interval limits for the logistic function were calculated on the basis of the standard error of the linear logistic predictor. DRs were compared with the McNemar test for ...
