RISAn Improved Weighted Total Least Squares Method with Applications in Linear Fitting and Coordinate Transformation
Publisher: American Society of Civil Engineers
Abstract: This paper presents an improved weighted total least squares (IWTLS) method for the errors-in-variables (EIV) model with applications in linear fitting and coordinate transformation. In addition, an improved constrained ...
Partial Total-Least-Squares Adjustment of Condition Equations with Application to a Rectangular Building Adjustment in a GIS
Publisher: American Society of Civil Engineers
Abstract: This paper presents a partial total-least-squares adjustment method for condition equations (PTLSC) in which the observation vector and coefficient matrix contain linearly correlated errors. In the proposed method, the ...
External Factors Affecting Determination of Mineral Powder Contact Angle with Capillary Rise Method
Publisher: American Society of Civil Engineers
Abstract: The difficulty of standardizing the test conditions for the contact angle (CA) of a mineral powder (MP) leads to results with poor repeatability. To solve this issue, external factors that influence the CA test of a MP ...
