Most of the fittings are integrated into the load-bearing structure through bonding. The metal fittings carry the high bearing loads that are transmitted into the pylon at the engine-pylon and wing-pylon interfaces. The load-bearing structure may also comprise a second central structure of a tubular shape composed of composite material and integrated with one end portion of the first central structure by bonding and/or mechanical fastening means.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, retrieve event data from a processor for sampling intervals, where the sampling intervals are evenly distributed, but the control points at which the event data is retrieved are unevenly distributed. The processor executes instructions for logical partitions, and the event data is associated with events that are detected by the processor during the sampling intervals. In response to an interrupt received from the processor at the control point, a determination is made whether the sample point has been reached. If the sample point has been reached, the event data is retrieved from the processor and an event counter is reset to a value that is calculated to cause the processor to include an identical number of the events in the sampling intervals. The value is calculated based on the event counter at the time control point, the event counter at a time of the sample point, and the number of events in the sampling interval.

Abstract: Methods and systems for providing multiple funding sources for health insurance and other approved healthcare expenses to full-time, hourly, part-time, seasonal, and temporary employees. Healthcare contributions for a single employee or for multiple workers in a family from more than one employer are placed in trust accounts established under separate Health Reimbursement Arrangements (HRAs) by each employer for use in paying qualified medical expenses of the employee and/or the employees' family. Each employer agrees to create HRAs for eligible employees and sends eligible employee data to a financial administrator. A trust account is created to hold the employer contributed HRA funds for the eligible employees. The eligible employees select a healthcare insurance policy, the premiums for which are paid out of each employee's HRA. The employee retains the HRA even if the employee's employment with the funding employer is terminated.

Abstract: A method and system for reducing or avoiding store misses with a data cache block zero (DCBZ) instruction in cooperation with the underlying hardware load stream prefetching support for helping to increase effective aggregate bandwith. The method identifies and classifies unique streams in a loop based on dependency and reuse analysis, and performs loop transformations, such as node splitting, loop distribution or stream unrolling to get the proper number of streams. Static prediction and run-time profile information are used to guide loop and stream selection. Compile-time loop cost analysis and run-time check code and versioning are used to determine the number of cache lines ahead of each reference for data cache line zeroing and to tolerate required data alignment relative to data cache lines.

Abstract: A process of digital electronic lien management is provided. Form data is stored in a first electronic database. A user adds lien input data in a second electronic database related to a specific construction lien project. A user then generates at least one lien form through insertion of the lien input data into the form data. The resultant form is transmitted to a recipient, who digitally modifies the form to create a modified version and electronically reconveys the modified version to the user.

A plurality of flow through channels are spaced outward of the substantially sleeve-shaped portion. Each flow through channel extends axially along the rod guide and has a maximum circumferential width greater than any gap in the radially outer surface of the erodible zone circumferentially aligned with and radially outward of the respective flow through channel. The radially outer surface of the erodible zone may have a cylindrical outer configuration, such that a radially outward substantially sleeve-shaped portion is provided for engagement with the tubing.

Abstract: The present invention is a low differential pressure relief valve made up of a valve body and an elastic membrane for downhole tools, especially rolling cutter drill bits. An aperture is formed in the membrane and a valve body with protruding end stops is mounted in the aperture. The thickness and shape of the valve body are such that the aperture is stretched when assembled. The amount the membrane is stretched and the geometry of the protruding end stop, control the differential relief pressure. The valve body and each end stop can be designed so that the pressure relief setting will be different, depending upon which side of the membrane has the higher pressure. The relief device may be adapted to be integral with existing elastic membrane type lubricant pressure compensation devices for downhole tools.

Abstract: A system and method are provided that allows the results of an instruction trace mechanism to globally restructure the instructions. The process reorders the instructions in an executable program, using an actual execution profile (or instruction address trace) for a selected workload, to improve utilization of the existing hardware architecture. The reordering of instructions is implemented at a global level (i.e., independent of procedure or other structural boundaries which maximizes speedup) running on various hardware platforms and adds the ability to preserve correctness and debuggability for reordered executables. An unconditional branch instruction is added at the memory locations where reordered instructions previously were stored. When a dynamic branch occurs, the program will attempt to access the instruction at the original address and the unconditional branch directs the program to the reordered location of the instruction and program integrity is maintained.

Abstract: A microprocessor performance monitor and instruction address break point facility are interconnected to provide finer granularity and performance monitoring. The microprocessor is initialized to collect processor statistics preselected prior to performance monitoring. Application start and stop instruction breakpoint addresses are preselected from a software program bounding instructions for which such statistics are desired. An exception handler is installed for instruction address breakpoints (IAB), enabling and disabling the performance monitor and stop addresses, respectively. The IAB register is then initalized to the start address, and the statistics counters are cleared. Upon starting the application, when the application start address instruction is executed, the breakpoint handler obtains control and enables the performance monitor counters, which count the desired statistics after returning from the breakpoint handler. Before returning, the handler sets the IAB register to the stop address.

Abstract: The present invention is a system and process for optimizing programs, having memory references, at the object code level. The process includes the computer-implemented steps of instrumenting each of the memory references to create an instrumented program, executing the instrumented program to capture effective address trace data for each of the memory references, analyzing the access patterns of the effective address trace data and, in response, reordering the memory references to create an optimized program.

Abstract: A method and system for optimizing branch prediction in an executable computer program compiled for execution on a pipelined processor that employs branch prediction. The source program is compiled and, in one embodiment, instrumented to collect branch selection statistics. The compiled program is run and statistics collected using the instrumentation or a standard trace program. The branch statistics are used to modify the executable program to cause branch prediction to be correct a majority of the time for the workload against which the program was run. In a computer system having a branch prediction bit, that bit is set or cleared to cause correct branch prediction a majority of the time.
