In this paper, we investigate the self-adaptive source separation problem for convolutively mixed signals. The proposed approach uses a recurrent structure adapted by a generic rule involving arbitrary separating functions. We rst analyze the stability of this class of algorithms. We then apply these results to some classical rules for instantaneous and convolutive mixtures that were proposed i...

The multiplicity distributions for individual fragment Z values in nuclear multifragmentation are binomial. The extracted maximum value of the multiplicity, mZ , is found to depend on Z according to mZ = Z0/Z, where Z0 is the source size. This is shown to be a strong indication of statistical coverage of fragmentation phase space. The inferred source sizes coincide with those extracted from the...

(a) In this question you are asked to show that randomness extraction is possible only from sources that are statistically close to sources with high min-entropy; thus, high minentropy is both sufficient and necessary for randomness extraction. More formally, let X be any distribution over {0, 1}n and let Ext : {0, 1}n × {0, 1}d → {0, 1}m. Suppose that Ext(X,Ud) is ǫ-close to the uniform distri...

This paper deals with the separation of two convolutively mixed signals. The proposed approach uses a recurrent structure adapted by a generic rule involving arbitrary separating functions. These functions should ideally be set so as to minimize the asymptotic error variance of the structure. However, these optimal functions are often unknown in practice. The proposed alternative is based on a ...

General Relativity gives that finitely many point masses between an observer and a light source create many images of the light source. Positions of these images are solutions of r(z) = z̄, where r(z) is a rational function. We study the number of solutions to p(z) = z̄ and r(z) = z̄, where p(z) and r(z) are polynomials and rational functions, respectively. Upper and lower bounds were previously o...

This paper presents the analysis for different control techniques in Z-source inverters. The voltage gain versus modulation index from simulation result is compared with the mathematical calculated voltage gain. Further detailed analysis of %THD, %harmonics of output voltage at different modulation indexes for different boosting techniques of a Z-source inverter are also performed with respect ...

In this paper, the operation principle of the Z-source inverter is analysed in detail. According to the characteristics of allowed short–shrougt zero state in the Z-source inverter, SPWM control method of the Zsource inverter is obtained by inserting fixed short–shrougt zero state into zero state of SPWM. It is simple and easily implemented in practice. However, in inductive load condition the ...

We present a deep 16.8 ks V -band image of the field of a candidate z=10 galaxy magnified by the foreground (z=0.25) cluster A1835. The image was obtained with FORS1 on VLT-Kueyen to test whether the V -band lies below the Lyman limit for this very high redshift candidate. A detection would unambiguously rule out that the source is at z=10. The 3σ detection limit of the image in the area of the...
