The progress of computer aided testing technology brings new development opportunity of aero-engine synthetic test. In order to improve aero-engine synthetic test level, a taken aero-engine synthetic test system is designed using advanced testing technology. User requirements of current situation are introduced, and then system function of test system is given, also related key technology is analyzed...
Teeth and mouth disease is one of the most common health problems complained by Indonesian society. Especially for children who still lack the awareness to maintain oral health and busy parents who sometimes causing delays in the handling of oral health in children. The purpose of this research is to make the application of expert system for the diagnosis of teeth and oral diseases in children. This...
An ARINC429 bus testing system is designed based on FFT processor, which aims at the technology of ARINC429 bus data communication. It controls tested module by controlling bus. In other words, the performance of ARINC 429 bus is tested by testing address bus and data bus. The testing system is based on ARINC429 bus specification and adopts universal ARINC429 special component DEI1016 and BD429 to...
The arrangement of atoms at the surface of a solid accounts for many of its properties: hardness, chemical activity, corrosion, etc. are dictated by the precise surface structure. Hence, finding it, has a broad range of technical and industrial applications. The ability to solve this problem opens the possibility of designing by computer materials with properties tailored to specific applications...
Information entropy is an effective description for the uncertainty of a system, and could be used for the symptom to detect the vibration changes of steam turbine. Based on the faulty signals collected from rotor test rig, three information entropy: singular spectrum entropy, power spectrum entropy, wavelet energy spectrum entropy were calculated as information entropy data. Probability neural networks(PNNs)...
