Nova Microwave staff has a thorough understanding of the working of ferrite and magnet materials and their application to develop electronic microwave circulators and isolators. The selection of basic ferrite material and magnet material has a significant effect on the overall performance and cost of circulators and isolators. The power handling, insertion loss, and labor required to manufacture these circulators and isolators is very dependent on this material selection. The ferrite material and magnet material required for circulators and iso ....etc

Abstract-
For near infrared imaging of neonatal head surrounded by cerebrospinal fluid layer, we have developed an imaging modality, which uses perturbation Monte-Carlo estimation of Jacobian of the forward model for photon propagation. In this case, we have shown that the conventional techniques, which uses diffusion approximation for light transport in tissue, fails to give the reconstruction of tissue optical proper ....etc

Wide angle X-ray scattering (WAXS) is an X-ray diffraction technique that is often used to determine the crystalline structure of polymers. This technique refers to the analysis of Bragg Peaks scattered to wide angles, implies that they are caused by sub-nanometer sized structures.Wide angle x-ray scattering is the same technique as Small-Angle X-ray Scattering (SAXS) with the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed.The technique is a time-honored but a somewhat out-of-favor tec ....etc

The conductivity may be obtained experimentally .
Further we can get by using eqn given below

but obtained may not be accurate but we will get an idea of magnitude of . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can say that T is extremely small f ....etc

ABSTRACT

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented
