A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator. Using 91 deceleration solenoids, the atoms were decelerated from an initial velocity of 580 m/s to final velocities as low as 105 m/s, corresponding to a removal of more than 95...

In many applications, the direction-of-arrival (DOA) estimation problem is of great interest. After blind separation of the signals incident onto the receiving sensor array, the DOAs can be estimated for each source individually. Non-Gaussian signals with negative kurtosis can be automatically captured by the constant modulus (CM) array, which is the most striking blind beamforming algorithm an...

Dual-gradient capillary electrochromatography (DG-CEC) was developed to provide superior performance with regard to the separation of ionized analytes; in this method, both the eluent composition and the applied voltage are varied during the separation procedure. As for the gradient in the eluent composition, a shift in the pH is employed to control not only the electrophoretic mobility, but al...

This paper addresses the problem of overlapping speech separation in a noisy room using a microphone array. The presented approach proposes a multistage processing framework to separate the desired sources and reduce the corruptive effects of noise, reverberation and interference. More specifically, 1) a beamformer separates the sources based on their location diversities, 2) a postfilter maxim...

Blind Source Separation is a problem whose solution is vital in numerous applications in Communications .We are proposing a multistage procedure to separate N original sources from N instantaneous mixtures. The goal is to extract the parameters of the unknown mixture in a deflation approach. In each stage of the procedure a novel cost function is applied . The cost function is derived from the ...

Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance of a multistage vacuum membrane distillation (MSVMD) which is thermodynamically similar to a multi-stage flash distillation (MSF) is evaluated for desalination, brine con...
