Robust 3 D Surface Property
نویسنده
چکیده
Estimation of local surface geometry (i.e. principle frame and principle quadric) is discussed. It is shown that surface tting methods are more robust that-nite diierence based approaches for a number of reasons. The local surface geometry is used to segment the surfaces into regions corresponding to smooth patches, separated by visibility boundaries, occluding contours, and ridges. Points within each surface patch are then classiied by the sign of the Gaussian and mean curvature .

Preferred Robust Response Surface Design with Missing Observations Based on Integrated TOPSIS-AHP Method
- Missing observations occur in experimental designs as a result of insufficient sampling, machine breakdown, high cost, and errors in the measurements. In nanomanufacturing, missing observations often appear in designs because the combination of factors or molecular structures selected by a designer cannot be experimented successfully. In the current paper, Box-Behnken and face-centered compos...
متن کاملConstruction of a surface pencil with a common special surface curve
In this study, we introduce a new type of surface curves called $D$-type curve. This curve is defined by the property that the unit Darboux vector $vec{W}_{0} $ of a surface curve $vec{r}(s)$ and unit surface normal $vec{n} $ along the curve $vec{r}(s)$ satisfy the condition $leftlangle vec{n} ,vec{W}_{0} rightrangle =text{constant}$. We point out that a $D$-type curve is a geodesic curve or an...
متن کاملA weighted metric method to optimize multi-response robust problems
In a robust parameter design (RPD) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. Response sur-face methodology (RSM) is one of the effective methods that can be employed for this purpose. Since quality of products or processes is usually evaluated through several quality ...
متن کاملNonlinear Robust Tracking Control of an Underwater Vehicle-Manipulator System
This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...
متن کاملThe analysis of residuals variation and outliers to obtain robust response surface
In this paper, the main idea is to compute the robust regression model, derived by experimentation, in order to achieve a model with minimum effects of outliers and fixed variation among different experimental runs. Both outliers and nonequality of residual variation can affect the response surface parameter estimation. The common way to estimate the regression model coefficients is the ordinar...
