The electric power supply chain network plays an important role in the world economy. It powers our homes, offices, and industries runs various forms of transportation. This paper considers design problem featuring differential pricing preventive maintenance. We demonstrate that this general model can be formulated as centralized decentralized models. A continuous approximation approach is used...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
The angular distribution of photoelectrons predicted for elliptically polarized light is shown to be the same as that predicted for partially polarized light having incoherent perpendicular electric field components equal to the electric field components along the major and minor axes of the ellipse. Increasing use by atomic experimenters of synchrotron radiation, which is known to be elliptica...
The article presents the results of calculations to justify choice transmission components and traction electric drive. parameters gearing transfer case differential has been substantiated. bearings is substantiated from conditions ensuring given resource strength for main gear.
In this research, the effect of the uniform electric field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot was studied using infinite potential model. In presence of strong electric field, due to the stark effect (perturbing electric field), the ground state energy would increase linearly. In presence of weak electric fields, the normalized bind...
Certain equations with integral constraints have as solutions time-periodic pulses of a field-like unknown while a current-like unknown oscillates periodically with time. A general asymptotic theory of this phenomenon, the generalized Gunn effect, has been found recently. Here we extend this theory to the case of nonlinearities having only one stable zero, which is the case for the usual Gunn e...

In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...
