We propose a technique for performing quantum state tomography of photonic polarization-encoded multiqubit states. Our method uses a single rotating wave plate, a polarizing beam splitter, and two photon-counting detectors per photon mode. As the wave plate rotates, the photon counters measure a pseudocontinuous signal which is then Fourier transformed. The density matrix of the state is recons...

In this paper, the work of Guria and Jana [1] is extended to include the slip condition at the lower porous plate. The upper plate is subjected to a constant injection –Vo and the lower plate to a transverse sinusoidal suction velocity distribution, so that the flow becomes three dimensional. Approximate solutions were found for velocity and temperature using regular perturbation techniques. Th...

Aisha Rafi ,Vivek Kumar Sharma Department of mathematics, Jagan-Nath University, Jaipur, India. __________________________________________________________________________________________ Abstract A study of the free convective flow of a viscous fluid past a hot vertical porous plate is done with the assumption that the suction velocity is constant and normal to the plate and the plate temperatu...

In this article, bending, buckling, and free vibration of viscoelastic sandwich plate with carbon nanotubes reinforced composite facesheets and an isotropic homogeneous core on viscoelastic foundation are presented using a new first order shear deformation theory. According to this theory, the number of unknown’s parameters and governing equations are reduced and also the using of shear correct...

Lap joints of commercially pure magnesium plates to aluminium plates (Magnesium plate on the top, and Aluminium plate, grade 1100, on the bottom side) were conducted by friction stir welding using various traveling and rotation speeds of the tool to investigate the effects of the welding parameters on the joint characteristics and strength. Defect-free lap joints were obtained in the welding tr...

Numerical simulations have been used to study the phenomenon of autorotation of a flat plate hinged about its center in a freestream. The focus of the paper is on examining the effect of Reynolds number and plate thickness ratio on vortex induced rotation. The numerical solver employed is based on a sharp interface, Cartesian grid method that allows us to simulate flow with moving boundaries on...

We deal with the study of momentum and heat transfer characteristics in a second-grade rotating flow past a porous plate. The analysis is performed when the suction velocity normal to the plate, as well as the external flow velocity, varies periodically with time. The plate is assumed at a higher temperature than the fluid. Analytic solutions for velocity, skin friction, and temperature are der...

From the rating plate data of an induction motor the nominal efficiency can be determined. Without detailed knowledge of equivalent circuit parameters, partial load behavior cannot be computed. Therefore, a combined calculation and estimation scheme is presented, where the consistent parameters of an equivalent circuit are elaborated, exactly matching the nominal operating point. From these par...
