An Interactive Training Device Using A Laser Video Disc, Mary C. Bertrand
An Interactive Training Device Using A Laser Video Disc, Mary C. Bertrand
Retrospective Theses and Dissertations
The goal of this paper is to develop an interactive training system. Although the system developed was used to train tank gunners, the system concepts are generic in that they can be applied to many training scenarios. Applications of computer-based training systems are briefly discussed. The system concepts are defined and hardware and software subsystems are outlined. An architectural overview will precede a detailed discussion of subsystems.
Computerized Displacement Data Analysis In Laser Speckle Photography, Bijan Chitsaz
Computerized Displacement Data Analysis In Laser Speckle Photography, Bijan Chitsaz
Retrospective Theses and Dissertations
Laser speckle photography is an experimental technique which provides a non-contract means for direct measurement of in-plane displacements of objects subjected to different loading conditions. It requires a camera system to record two images of the object that are illuminated with laser light on a high resolution film. The double-exposure film (specklegram) is a permanent record of the displacement information of the object. Point-by-point analysis of the specklegram will yield the displacement data, but requires considerable time to complete the data reduction. An automated data analysis system is developed and described in this report. He-Ne laser and computer-controlled translation stages …
Optimization Analysis For Alignment Criteria And Installation Of Gravity Flow Underground Pipe, Eugene N. Balter
Optimization Analysis For Alignment Criteria And Installation Of Gravity Flow Underground Pipe, Eugene N. Balter
Retrospective Theses and Dissertations
In 1982 the Business Roundtable prepared several reports which investigated various aspects of construction which posed significant research opportunities. Their findings placed piping construction in the group of activities categorized as having "highest potential" for improvements based on inefficiency, or construction difficulty and proportionate costs. It was estimated that over $1 billion could be saved annually if the difficulty in the piping industry was improved to only average of other areas. Further investigation into the piping area showed that the alignment process took 20% of the cycle time for installation and ranked either first or second as compared to other …
