This paper describes a system called PDS, a forward chaining, rule-based architecture designed for the online, realtime diagnosis of machine processes. Two issues arise in the application of expert systems to the analysis of sensor-based data: spurious readings and sensor degradation. PDS implements techniques called retrospective analysis and metadiagnosis as solutions to these problems. These...

A Multi-body contacting Thermal-Elastic-Hydro Model, MTEHM has been established in this study. And which applied to analysis the leakage behavior of No.1 seal RCP hydrostatic seal. The hydro-model is based on 2D Reynolds equation and programmed by M-code. An interface program written C carried out. used transit end face pressure value from elastic-solid model. FEA multi-body method taken into o...

Over a century ago George Westinghouse, with the support of Nikola Tesla, defeated Thomas Edison in the ‘War of Currents’, thereby successfully establishing alternating current (AC) as the primary mode of electricity transmission and distribution. Large power plants such as coal, nuclear and hydro, are often located far from consumption centres. With transformers, the voltage level of AC power ...

This paper presents the qualification of newly developed Westinghouse lattice physics code PARAGON2. PARAGON2 uses high energy resolution in solution transport equation. The objective this is to demonstrate that accurately predicts integral and critical experiments. experiments are used assess predictions fine neutronics parameters such as: resonance integrals radial profiles reactions rates, i...

in the present work, multidimensional modeling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission a...

a period of years, endeavored to offset the low salary disadvantages of government employment by offering special training and educational opportunities. The student trainee program is initiated by announcements, followed by direct contacts with teachers and students. Selected groups of high school graduates and college students are brought in to work as technical aides for the summer period. N...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
