The amplitude-encoding case of the double random phase encoding technique is examined by defining a cost function as a metric to compare an attempted decryption against the corresponding original input image. For the case when a cipher-text pair has been obtained and the correct decryption key is unknown, an iterative attack technique can be employed to ascertain the key. During such an attack ...

The complete Cd-Pr equilibrium phase diagram was investigated with a combination of powder-XRD, SEM and DTA. All intermetallic compounds within this system, already reported in literature, could be confirmed: CdPr, Cd2Pr, Cd3Pr, Cd45Pr11, Cd58Pr13, Cd6Pr and Cd11Pr. The corresponding phase boundaries were determined at distinct temperatures. The homogeneity range of the high-temperature allotro...

In this work, the thermal and electrical performances of chalcogenide-based phase change memory cell were investigated. We have investigated the current reduction issue for CRAM cell theoretically and experimentally. It was found that the value of programming current is highly dependent on the materials and device structure. The effects of materials and cell geometry, structure, and size on the...

Using the supersymmetric quantum mechanics we investigate the wave function-sensitive properties of the supersymmetric potentials which have received a lot of attention in the literature recently. We show that a su-perdeep potential and its phase-equivalent shallow-partner potential give very similar rms values for the weakly bound systems such as the deuteron and 11 Be nuclei. Although the cor...

Three-dimensional phase-field simulations are employed to investigate rod-type eutectic growth morphologies in confined geometry. Distinct steady-state solutions are found to depend on this confinement effect with the rod array basis vectors and their included angle (α) changing to accommodate the geometrical constraint. Specific morphologies are observed, including rods of circular cross secti...

This paper describes the investigation of the grid-connected three-phase inverter for photovoltaic (PV) application. The inverter control system modeling is carried out in MATLAB/SIMULINK environment. With the aids of the proportional-integral controllers, sinusoidal pulse-width modulation (SPWM) control technique and Park transformation, the inverter control system managed to convert PV power ...

We have investigated the coupled structural and electronic phase transition in the rare-earth ternary silicide Lu2Ir3Si5 by means of electrical resistivity , Seebeck coefficient S , as well as thermal conductivity measurements. Near the phase transition, pronounced anomalies in these transport properties with a significantly large hysteresis of about 40 K were noticed. By comparing the transiti...

Multi-port microchannel tubes are increasingly popular for use in a variety of heat transfer applications, primarily for automotive condensers and radiators, but also in a variety of refrigeration and air conditioning applications. These channels offer a greater surface area to volume ratio, providing for enhanced heat transfer over a conventional tube in many applications. Previous research ha...
