Abstract: Deformation measurements on man‐made structures are important because they provide an independent check on whether or not the structure is exhibiting a safe deformation behavior. These measurements are especially critical ...

Abstract: Deformation measurements on large man‐made structures are important, especially in the first few years after construction is complete. In this paper, after a distinction is made between geometric deformation analysis and ...

Abstract: A new method of leveling, suitable for high-precision industrial applications, is described. The observation procedure involves only minor modifications to the standard observation procedure for precise leveling. The ...

Abstract: A new method of checking the alignment of parallel rolls, while they are rotating, is described in this paper. The method utilizes the autoreflection technique, along with a strobe light and photoelectric trigger, to ...

Abstract: Precise machinery surveys, incorporating laser targeting, can now be carried out in near real time using an electronic theodolite system. Within the Industrial Alignment Project, a cooperative research and development ...

Abstract: 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, ...

Abstract: Precise three-dimensional positioning by the hidden point bar method is investigated. The investigation includes development of both closed form and least squares solutions, as well as calibration of the hidden point bar. ...

Abstract: Time aloft and distance traveled in free flight with a paraglider are determined by three factors: weather conditions, pilot skill, and paraglider performance. The latter factor can be represented in a performance curve. ...

Abstract: Precise heighting by the hidden point bar method is investigated. The investigation includes development of the mathematical model, calibration of the hidden point bar, and comparison with precise leveling and precise trig ...

Abstract: Since 1986, measurements of deformations have been made on a section of large‐diameter buried natural gas pipeline in northern Alberta. Precise conventional survey techniques are used to measure the deformations. ...
