This work considers a means of implementing a detection algorithm for multiple stuck-at faults occurring within the structure of a generalized tree using, as the testing machines, a set of generalized sequential trees. It is shown that the testing machine can be implemented on a set of trees of the same depth as that of the tree which is being tested. Modifications are made to the generalized tree structure so as to facilitate the testing algorithm and in order to simplify initialization. The testing algorithm is modified so as to test this modified structure. In addition, after testing is complete, two means of reinitialization of the sequential trees are discussed. / Master of Science

This thesis describes research to implement a Bayesian belief network based expert system to solve a real-world diagnostic problem troubleshooting integrated circuit (IC) testing machines. Several models of the IC tester diagnostic problem were developed in belief networks, and one of these models was implemented using Symbolic Probabilistic Inference (SPI). The difficulties and advantages encountered in the process are described in this thesis. It was observed that modelling with interdependencies in belief networks simplified the knowledge engineering task for the IC tester diagnosis problem, by avoiding procedural knowledge and sticking just to diagnostic component's interdependencies. Several general model frameworks evolved through knowledge engineering to capture diagnostic expertise that facilitated expanding and modifying the networks. However, model implementation was restricted to a small portion of the modelling - contact resistance failures - because evaluation of the probability distributions could not be made fast enough to expand the code to a complete model with real-time diagnosis. Further research is recommended to create new methods, or refine existing methods, to speed evaluation of the models created in this research. If this can be done, more complete diagnosis can be achieved. / Graduation date: 1994

This study is concerned with the design of vehicle structures through the use of Fatigue Equivalent Static Loads (FESL). A large percentage of failures of mechanical structures can be attributed to fatigue. Furthermore, it is also generally accepted that defective structural design is mostly caused by insufficient knowledge of the input loading. The fatigue loads experienced by vehicle structures are especially difficult to quantify. In the current competitive markets, it is essential to use a pro-active, timely and cost effective process to solve fatigue related problems. The heart of the FESL methodology is the ability to condense a large amount of input load data into a single fatigue load. This is achieved by calculating the damage of the measurements and converting it to an equivalent stress, through the use of a calibration matrix obtained from a unit-load finite element analysis. A Fatigue Equivalent Static Load can now be determined, and the vehicle structure can be evaluated for durability. / Dissertation (M Eng (Mechanical Engineering))--University of Pretoria, 2003. / Mechanical and Aeronautical Engineering / unrestricted
