The present paper addresses systematic approach to Condition-Based Maintenance, and research results at the University of South Carolina Condition-Based Maintenance Research Center, directly related to U.S. Army rotorcraft Vibration Management Enhancement Program. The paper gives an analysis of the CBM concept and its functional layers, such as condition(More)
We present infrared observations of the young, oxygen-rich supernova remnant 1E 0102.2-7219 (E0102) in the Small Magellanic Cloud, obtained with the Spitzer Space Telescope. The remnant is detected at 24 μm but not at 8 or 70 μm and has a filled morphology with two prominent filaments. We find evidence for the existence of up to 8× 10 M⊙ of hot dust (Td ∼(More)
Radar system has been using a hybrid of analog and digital beamforming. Sub-arrays of phase shifters in the analog domain are digitized at the sub-array outputs for further digital beamforming processing. Such system suffers from limited bandwidth and is unable to create more than one simultaneous beam. Digital time delay beamforming brings many benefits(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 recordkeeping 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)
BACKGROUND Field trials have demonstrated the efficacy of insecticide-treated nets, and the WHO has recently endorsed a shift toward Long-Lasting Insecticide Treated nets (LLINs) due to factors such as reduced distribution costs. However, the need for LLINs poses several challenges. Is it possible to manufacture LLINs in large quantities in the African(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)
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)
