Response spectral moments are useful for system reliability analysis.Usually,spectral mo-ments are calculated by the frequency domain method.Based on the time d
For first-order nonlinear nonholonomic systems,the present paper proves that thed-δ operations are commutative and derives the equation of motion without makin
Numerical results show that an external magnetic field may influence significantly the flow pattern inthe molten semiconductor of Czochralski crystal growth. Th
