Goldreich suggested candidates of one-way functions and pseudorandom generators included in NC. It is known that randomly generated Goldreich’s generator using (r−1)-wise independent predicates with n input variables and m = Cn output variables is not pseudorandom generator with high probability for sufficiently large constant C. Most of the previous works assume that the alphabet is binary and...

We demonstrate a degenerate parametric oscillator in a silicon nitride microresonator. We use two frequency-detuned pump waves to perform parametric four-wave mixing and operate in the normal group-velocity dispersion regime to produce signal and idler fields that are frequency degenerate. Our theoretical modeling shows that this regime enables generation of bimodal phase states, analogous to t...

proper forest management needs quantitative and precise estimates of forest stands characteristics. remotely sensed imageries, due to accurate and broad spatial information, has become a cost-effective tool in forest management. classification of forest attributes and generation of thematic maps are among the common applications of remote sensing. the objective of this study was to optimize the...

Copulas enable to specifymultivariate distributions with givenmarginals.Various parametric proposals weremade in the literature for these quantities, mainly in the bivariate case. They can be systematically derived from multivariate distributions with known marginals, yielding e.g. the normal and the Student copulas. Alternatively, one can restrict his/her interest to a sub-family of copulas na...

in this study, an extended stress-based forming limit diagram (fld) for prediction of necking based on the marciniak and kucznski (m-k) model is represented and applied in tube hydroforming. the bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. this adaptive simulation technique is based on the ability to detect the onset and g...

(b) Usually (in practice), the k used for signing is not generated completely at random, but by using a pseudorandom generator. Again, in practice, people use a simple “pseudorandom” generator such as the linear congruential generator. A linear congruential generator LCG, on input a seed s0 outputs a sequence (s1, s2, . . . , sn) such that si = asi−1 + b(mod q). (where a and b are assumed to be...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

Direct drive wind turbine generators are gaining importance for light weight, compact design in wind power generation. A new design approach of superconducting wind generator having both axial and radial air gaps between stator and superconducting rotor winding is selected for this simulation work. This paper deals with the simulation of magnetic flux distribution in stator and rotor coil of th...
