Smart noise jamming is a new style against radar, which plays an important role in modern radar electronic warfare. In order to solve the complex problem of convolutional smart suppression with different time delay and frequency modulation, novel method based on optimized atomic dictionary decomposition by estimating significant parameters proposed this paper. First, dual channel signal informa...

By using the decomposition of decoherence-free subalgebra N(T) in direct integrals factors, we obtain a structure theorem for every uniformly continuous quantum Markov semigroup. Moreover, prove that when there exists faithful normal invariant state, has to be atomic and decoherence takes place.

The dynamics of N2O decomposition to gaseous nitrogen and oxygen over HZSM-5 catalysts with a low iron content (200 and 1000 ppm) was studied by the transient response method in the temperature range 523–653 K. The active catalysts were prepared from HZSM-5 with Fe in the framework on its steaming at 823 K followed by thermal activation in He at 1323 K. Two main steps were distinguished in the ...

In this experimental work, PbS/ZnS/ZnO nanocomposite was synthesized via a simple co-precipitation method. The effect of Zn2+/Pb2+ mole ratio was investigated on the product size and morphology. The products were characterized via scanning electron microscopy to obtain product size and morphology. The optical properties of the nanocomposites were studied by ultra violet-visible spectroscopy. Ph...

in this paper, we use modified laplace decomposition method to solving initial value problems (ivp) of the second order ordinary differential equations. theproposed method can be applied to linear and nonlinearproblems
