The AH-64 helicopter tail rotor gearbox is a grease lubricated right-angle transmission which frequently leaks through both its input and output seals. An experiment was designed to create a worst-case scenario for a leaking output seal on three different high-life gearboxes, which were to be run for 500 hours in a seeded fault condition. The test objective(More)
The University of South Carolina is currently implementing the procedure presented in the publication " Integration of Maintenance Management Systems and Health Monitoring Systems through Historical Data Investigation. " This particular application is attempting to merge TAMMS-A records with data collected from Intelligent Automation Corporation's Vibration(More)
Maintenance Management Systems (MMS) are the core of traditional maintenance record-keeping practices and often facilitate the usage of textual descriptions of faults and actions performed on a vehicle. Recently developed Health and Usage Monitoring Systems (HUMS) are capable of directly monitoring vehicle component parameters; however, attempts to link(More)
Our fourth component of research is focusing on expanding the Cost and Benefit Analysis (CBA) has been carried out to reflect on the whole CBM roadmap. This includes the cost savings in parts cost, operational support, the increase in mission capability rates, the decrease in scheduled and non-scheduled maintenance, and the increase in total flight time. It(More)
One of the most expensive and time consuming tasks relating to Condition Based Maintenance involves the testing of mechanical components for CBM. A scientific plan is being developed to identify components that will return the most value within a short time for implementation of CBM. This plan is also based on the historical (TAMMS-A and VMU) data that we(More)
Tenascin-C (TNC), a major component of the extracellular matrix, is strongly upregulated after injuries of the central nervous system (CNS) but its role in tissue repair is not understood. Both regeneration promoting and inhibiting roles of TNC have been proposed considering its abilities to both support and restrict neurite outgrowth in vitro. Here, we(More)
In critical conditions, gears operate with insufficient lubrication and efforts are made to improve the life of these gears against wear. A local gear-tooth defect such as a fatigue crack, pit, or chip weakens a tooth and causes transient events in the system. The magnitude and duration of these events depend mainly upon the severity of the defect and the(More)
BACKGROUND Developing novel drugs from traditional medicinal knowledge can serve as a means to improve public health. Yet countries in sub-Saharan Africa face barriers in translating traditional medicinal knowledge into commercially viable health products. Barriers in moving along the road towards making a new drug available include insufficient(More)
—GPU (Graphics Processing Unit) is emerging as an efficient and scalable accelerator for data-parallel work-loads in various applications ranging from tablet PCs to HPC (High Performance Computing) mainframes. Unlike traditional 3D graphics rendering, general-purpose compute applications demand stringent assurance of reliability. Therefore, single error(More)
