    • Basic Concepts of <b><i>L</i></b><sub>1</sub> Norm Minimization for Surveying Applications 

      John Marshall; James Bethel (American Society of Civil Engineers, 1996)
      norm minimization is a powerful mathematical tool used in surveying to detect gross errors in survey data. We describe the basic theory underlying
    • Finite Sample Breakdown Points of Outlier Detection Procedures 

      Şerif Hekimoğlu (American Society of Civil Engineers, 1997)
      The conventional iterative outlier detection procedures (CIODP), such as the Baarda-, Pope-, or t-testing procedure, based on the least-squares estimation (LSE) are used to detect the outliers in geodesy. Since the finite ...
    • Exploitation of Linear Features in Surveying and Photogrammetry 

      Edward M. Mikhail; Kanok Weerawong (American Society of Civil Engineers, 1997)
      Modeling of linear features, particularly straight lines and circles, in two-dimensional (2D) and three-dimensional (3D) spaces, is developed, with specific consideration of independent descriptors. This is followed by the ...
    • Discussions: Intersection of Spiral Curve with Circle 

      Thomas G. Davis; Sum Lin; K. S. Li (American Society of Civil Engineers, 1996)
    • Geometric Calibration of CCD Camera Using Planar Object 

      Mohammed Taleb Obaidat; Kam W. Wong (American Society of Civil Engineers, 1996)
      A method of geometric calibration of charge-coupled device (CCD) vision systems for metric measurement has been developed. The method does not require a special calibration facility or accurately surveyed three-dimensional ...
    • Deformation, Alignment, and Vibration in Large Turbine-Generator Set 

      W. F. Teskey; J. W. Lovse; N. N. Al-Hanbali (American Society of Civil Engineers, 1996)
      Within the Industrial Alignment Project (1990–93) and the Dynamic Alignment Project (1993–96), collaborative research and development efforts involving the Department of Geomatics Engineering at The University of Calgary, ...
    • GPS High Accuracy Geodetic Networks in Mexico 

      Tomás Soler; Gabriel Álvarez-García; Antonio Hernández-Navarro; Richard H. Foote (American Society of Civil Engineers, 1996)
      Recently, Mexico's
    • Technique for Precise Measurement of Large-Scale Silos and Tanks 

      Xiaoli Ding; Richard Coleman; J. Michael Rotter (American Society of Civil Engineers, 1996)
      Geometric imperfections in thin-shell structures such as silos and tanks need to be measured to assess the buckling strength of the structures, and to develop new structure design criteria. A number of difficulties are ...
    • Concept of Lateral Change of Acceleration 

      Orhan Baykal (American Society of Civil Engineers, 1996)
      Due to the very high speeds on railways and motorways, the relationship between the horizontal and vertical geometry of roads with respect to the road dynamics has become very important. In recent publications, new transition ...
