Abstract: Systems and methods for determining a difference in performance for a software program processing input data for multiple threads based on different termination time periods for handling an exception. In some aspects, the system receives input data and corresponding performance data for multiple threads with respect to a first termination time period for terminating the thread when an exception is detected. The system processes the input data to generate corresponding performance data for the multiple threads with respect to a second termination time period for terminating the thread when the exception is detected. The system determines a difference in performance for a particular thread based on performance data with respect to the first termination time period and corresponding performance data with respect to the second termination time period.

Abstract: The invention comprises a brace which may be used in a conventional valve assembly for holding the packing gland flange in place while valve components are repacked, repaired, and/or replaced. The brace is put in place around the valve stem and wedged between the gland flange and the yoke. The brace comprises a section of pipe cut into two longitudinal sections and held in place by a pipe clamp. The brace is preloaded by adjustment of jacking screws located between the brace body and the valve yoke. When in place, the brace will hold the valve gland flange together while the gland flange bolts e.g., are replaced. The brace may be left in position if desired as added reinforcement for perhaps a cracked gland flange.
