      Amr A. Oloufa (American Society of Civil Engineers, 1991)
      Results from volume calculation of soils are a major input in heavy construction and earth‐moving operations. Traditional methods for volume calculation have been based on the application of the end‐area method or prismoidal ...
    • Automated Identification Systems—Focus on Bar Coding 

      William J. Rasdorf; Mark J. Herbert (American Society of Civil Engineers, 1990)
      Automated inventory control has been used for many years in such industries as manufacturing, automotive, and retail grocery. These industries have recognized technologies such as bar coding, magnetic stripe, optical ...
    • Manipulating Shape and Its Function 

      Nelson C. Baker; Steven J. Fenves (American Society of Civil Engineers, 1990)
      Shape and other geometric information about design objects play a pivotal role in design. Shape grammars provide a technique to manipulate and reason with shape. A shape grammar consists of a set of productions on rules ...
    • Process Planning for Automated Stone Cutting 

      Leonhard E. Bernold; Davis B. Reinhart (American Society of Civil Engineers, 1990)
      The need to increase productivity, quality, and effectiveness in construction challenges researchers to seek and develop bold innovative changes. Technological adaptation of successful concepts from other industries into ...
    • Knowledge‐Based Tool for Decomposing Complex Design Problems 

      James L. Rogers (American Society of Civil Engineers, 1990)
      A design problem is viewed as a complex system divisible into modules. For designs based on novel concepts, such as designs for space platforms, the determination of subsystems, their interactions, and the participating ...
    • Automatic Mesh Generator for Use in Two‐Dimensional <i>h‐p</i> Analysis 

      Marcel K. Georges; Mark S. Shephard (American Society of Civil Engineers, 1990)
      Paper presents a fully automatic mesh generator specifically designed to create the coarse, exponentially graded meshes needed for the optimal application of the
    • Editorial 

      Paul Teicholz; C. William Ibbs (American Society of Civil Engineers, 1990)
    • Geotechnical Data Management System 

      Fook‐Hou Lee; Thiam‐Soon Tan; G. P. Karunaratne; Seng‐Lip Lee (American Society of Civil Engineers, 1990)
      For many geotechnical projects in both the field and the laboratory, there is a trend toward using automatic data acquisition systems to collect information. This usually leads to the generation of a large volume of data, ...
    • Computerized Applications for Station Equations 

      James W. Epps; Marion W. Corey (American Society of Civil Engineers, 1990)
      The general form of a station equation does not produce a constant relationship between the ahead station number and the back station number. For this reason, station equations are considered only in the most sophisticated ...
    • REPCON: Expert System for Building Repairs 

      P. Kalyanasundaram; S. Rajeev; H. Udayakumar (American Society of Civil Engineers, 1990)
      Buildings, whether adequately designed or not, develop a variety of problems over the years. The choice of an appropriate repair method requires systematic observations of the symptoms and relating them to their probable ...
    • Automating Building Design Process with KBES 

      Claude Bédard; Krishnan Gowri (American Society of Civil Engineers, 1990)
      The building design process represents such a highly complex activity that only restricted and well‐structured tasks have been successfully computerized until now. The process is still largely characterized by the contribution ...
    • Knowledge‐Based Prototype for Improving Scheduling Productivity
