Problem statement: Diagnosis x-ray radiation safety is key in medical examination. The quantity of patient radiation doses is beneficial for radiation protection of the patient. It was proposed that the equation for estimating the output (milliReongent, mR) from x-ray machines. Approach: A was 0.5, 0.8 and 1.0 for single phase, three phases and high frequency x-ray machines, respectively. To co...

Conductivity of molten alkali metal chlorides is the foundation molten-salt electrolysis process. In study, equilibrium molecular dynamics was performed to investigate ionic conductivities chloride binary systems. The calculated values were in good agreement with experimental results. Simple databases for conductivity have been built based on verified algorithm. Mathematic expressions vs. tempe...

The relevance of sheet processing technology, which finds increasing application, is given. Efficient equipment for metal and mounting justified proposed. This article deals with upcut shears’ operation. solution to the mathematic model manual shears using Mathcad provided.

The remaining useful lifetime (RUL) of proton exchange membrane fuel cell (PEMFC) has been influenced by the heterogeneous distribution. In this presented paper, a novel method considering internal heterogeneity is proposed and investigated to manage operation thus prolonging lifetime. This including mathematic steps quantification, normalization, coordinate transformation, converts conventiona...

Piezoelectric transducer (PT) is the key component in power ultrasonics. Its vibration amplitude directly reflects performance of transducer. The real time measurement seldomly reported and difficult to be realized due high frequency confined space accommodate a sensor. Currently, there are no viable solutions for monitoring when tool engaged material. We present time, low-cost strategy PT, inc...

The purpose of this paper is to investigate the effect manufacturing errors on performance a gas-dynamic bearing gyroscope. Five kinds including taper error, oval trigone eccentricity axis, and angular deviation axis are studied. A mathematic model these established describe variation gas film thickness. Reynolds equation solved, perturbation method applied analyze with errors. Based analysis, ...
