Abstract: Determining an active jacking force of a tunneling closely undercrossing existing station, includes: acquiring design parameters of stations, and geological parameters of a construction site; obtaining a stress solution expression of the active jacking force on the existing station to obtain a stress solution of any point in a semi-infinite space under the action of a vertical load, replacing the vertical load with a vertical load acting on the existing station, and obtain a vertical stress solution of the existing station; obtaining a relational expression between the deflection and the stress solution of the existing station; and substituting the stress solution expression of the active jacking force into the relational expression between the deflection and the stress solution of the existing station according to boundary conditions at both ends of a beam on elastic foundation to obtain the active jacking force that controls the deflection of the existing station.

Abstract: In one embodiment, a method includes receiving logfile data, parsing the logfile data into parsed data elements and acquiring at least one contextual data element in relation to the parsed data elements. The method further includes structuring the parsed data elements and the at least one contextual data element as instances of a multirepresentational time-series log entry. In addition, the method includes publishing real-time time-series performance data and determining a user viewing context. Furthermore, the method includes automatically correlating the user viewing context to at least one dimension. Additionally, the method includes filtering the log-entry instances by the at least one dimension to yield filtered log-entry instances. Also, the method includes pivoting the filtered log-entry instances on one or more dimensions, the pivoting yielding pivoted data. In addition, the method includes publishing the pivoted data to a user interface.

Abstract: Simulation data can be generated using a linear curve simplification and reverse simplification technique. The linear curve simplification and reverse simplification technique can facilitate the generation of simulation data from existing data where the simulation data will exhibit the same curve pattern as the existing data but with a degree of variation. In this way, varying sets of simulation data for a particular environment can be easily generated.

Abstract: Embodiments of the present invention include systems and methods for dynamically adjusting instrumentation scope of a profiler gent. The method for dynamically adjusting an instrumentation scope of a profiler agent includes: supplying an initial instrumentation scope profile (ISP) that defines an instrumentation scope of a profiler agent to the profiler agent; receiving performance data of a call tree from the profiler agent based on the initial ISP; adjusting the instrumentation scope; updating the initial ISP based on the adjusted instrumentation scope; and supplying the updated ISP to the profiler agent. Adjusting the instrumentation scope includes at least one of expanding a child node of the call tree and excluding a child node of the call tree from the instrumentation scope.

Abstract: In an embodiment, a method is performed by a computer system. The method includes automatically receiving, from an agent on a client device that is physically distinct from the computer system, a cookie corresponding to an active user session on a website. The active user session is previously established on the website in response to the website receiving valid user credentials from the client device. The method also includes storing the cookie in memory. In addition, the method includes, via the cookie, collecting information from the website over the active user session, thereby reusing the active user session. Further, the method includes periodically sending a dummy request comprising the cookie to the website, thereby preserving the active user session.
