Empirical mode decomposition is investigated as a tool to determine the phase and frequency and to study phase synchronization between complex chaotic oscillators. Within this approach, the oscillator is characterized by a spectrum of frequencies corresponding to the empirical modes. First, the phase and frequency of the oscillators resulting from two well-known methods, based on modified varia...

Multi-phase machines are considered serious contenders as compared to the three phase machines for variable applications in generating mode. This paper presents the transient performance analysis of a multi-phase induction machine operating in six-phase mode for power generation. In this paper the simulation and experimental analysis of a six-phase machine in generating mode have been made. The...

Parkinson Disease is a neurological syndrome, characterized by resting tremor, reduced body movement and difficulty in maintaining proper posture. In this article I demonstrate a new method of parkinsonism diagnosis using Empirical Mode Decomposition (EMD) based on body movement synchronization analysis. EMD is a new method of signal decomposition into its monocomponents, so called Intrinsic Mo...

The kinematics of dust particles during the early stage of mode-coupling induced melting of a two-dimensional plasma crystal is explored. It is found that the formation of the hybrid mode causes the particle vibrations to partially synchronize at the hybrid frequency. Phase- and frequency-locked hybrid particle motion in both vertical and horizontal directions (hybrid mode) is observed. The sys...

A fully integrated dual-mode frequency synthesizer for GSM and Wideband CDMA (WCDMA) is presented. The synthesizer is designed to maximize hardware sharing between the two modes by applying fractional frequency synthesis to GSM mode and integer frequency synthesis to WCDMA mode. The shared components include phase frequency detector (PFD), charge pump (CP), loop filter, integer frequency divide...

This paper presents results of a design that uses CMOS current mode logic that can be used to implement the high precision, speed critical elements of the mixed-signal systems. The design is based upon the 0.25-μm CMOS TSMC process. The propagation delays of the new current mode logic are compared to those of equivalent gates implemented in conventional CMOS logic. The results show a propagatio...

We propose and implement a new scheme of generating the optical Einstein-Podolsky-Rosen entangled state. Parametric down-conversion in two nonlinear crystals, positioned back-to-back in the waist of a pump beam, produces single-mode squeezed vacuum states in orthogonal polarization modes; a subsequent beam splitting entangles them and generates the Einstein-Podolsky-Rosen state. The technique t...

A new solid phase liquid crystal microlens array has been applied to Polarisation Activated Microlens flat panel displays that can be electrically reconfigured between a full performance 2D mode and a low cross talk autostereoscopic 3D mode. The solid phase microlens array enables significant reductions in device thickness and improved ruggedness compared to nematic phase liquid crystalline mic...

Longitudinal strains in optical fibers have been found to produce a large differential phase shift between the first-and second-order spatial modes propagating in a two-mode fiber. This differential phase shift between the modes is both calculated and measured to be dispersive with respect to wavelength. For fibers with highly elliptical core geometries, which propagate only one lobe orientatio...
