Abstract: An application records memory allocations and releases as they occur over time, and an analysis system presents characteristic memory utilization patterns to a user for review and analysis. A variety of sampling techniques are used to minimize the impact of this memory utilization monitoring on the performance of the application, and the analysis system is configured to estimate the overall memory utilization based on these samples. Because these samples of the memory allocations are taken continuously as the application is running, the analysis system can provide visualizations of the memory utilization patterns that allow a user to easily recognize anomalous behavior. The analysis system includes an interactive interface that allows the user to trace the cause of the presented memory utilization patterns, and provides statistics regarding memory allocation and release to guide the user in this analysis.

Abstract: Recently two techniques using free solution electrophoresis to separate charged-uncharged polymer conjugates have proven successful: End Labeled Free Solution Electrophoresis (ELFSE) for DNA sequencing, and Free Solution Conjugate Electrophoresis (FSCE) for molar mass profiling of uncharged polymers. Previous attempts have been made to analyze experimental data generated by these new techniques for the electrophoresis of molecules with varying charge distributions. However, the importance of the ends of the polymers in determining the polymer's overall mobility was neglected in previous work. Through a careful investigation and a reanalysis of the experimental data, it is determined here that this “end effect” critically impacts the behavior of polymers and charged-uncharged polymer conjugates during electrophoresis.

Abstract: Techniques for gathering execution information about an application, such as a distributed application, are described. Key communication points in cross execution context calls, such as remote procedure calls, are determined and control is transferred to interception routines to insert and extract execution information. Outgoing remote procedure calls are intercepted on a client that inserts call origin information into the request sent to a server system. The server system intercepts and extracts the call origin information and additionally inserts other information in a response sent to the client system upon completion of a remote procedure call. In turn, the client system intercepts the response and extracts other performance information. On each client and server system, information is gathered by a reader and forwarded to a local collector. Program execution data may be collected and correlated for coordinated application monitoring.

Abstract: An apparatus and method for fabricating heavy duty blasting mats. A plurality of parallel spaced curved steel rods are clamped at their lower ends in a frame so that reclaimed automobile tire sections can be threaded in a prearranged pattern onto the free upper ends thereof. When the rods are fully loaded, the upper ends of the rods are clamped in an upper frame, and the lower ends are released. A hydraulically operated rake is actuated to push the assembled tire sections off the lower ends of the rods and onto steel cables flexibly and releasably coupled thereto.
