Previous work on tracking source locations has focused on tracking lines through multiple revisions of software. In this paper, we explore a new technique for tracking statements, rather than lines, across multiple revisions of Java source code. We show that our statement-tracking technique achieves comparable accuracy for source code than the most accurate line-tracking techniques, while also safely...
Improper installation of fuses in cutouts can result in unplanned outages, some at the feeder level. Whenever installing fuses in fuse cutout fuse tubes, the supplier's instructions should be followed. Key among these is the proper torque on the cap of the fuse tube. Loose caps result in heating. This heating acts as a preload and causes faster fuse clearing than TCC's indicate. This results in unexplained...
We present an automatic fault localization technique which leverages time spectra as abstractions for program executions. Time spectra have been traditionally used for performance debugging. By contrast, we use them for functional correctness debugging by identifying pieces of program code that take a "suspicious" amount of time to execute. The approach can be summarized as follows: time...
An adaptive controller for bilinear plants without delay and with stable inverses is defined based upon a bilinear model predictive control law and a classical recursive identification algorithm. For the case with no disturbance both the control error and the identification error converge to zero. For the case with a bounded disturbance, the control error is bounded and the identification converges...
