This paper presents an autonomous hybrid generation system consisting of wind turbine generators (WTG), a diesel engine generator (DEG), fuel cell (FC), a battery energy storage system (BESS) and an aqua electrolyzer (AE). The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The power system frequency deviates for the sudden changes in load and generation. The output ...

Expanding the Length of a Pseudo-Random Number Generator We now want to show how a pseudo-random number generator that only does a little bit of expansion, can be used to construct a pseudo-random generator that does a lot of expansion. The idea is that we view G(s) as consisting of “stuff” that we can spit out, together with a new seed that we feed back into the generator, etc., a polynomial n...

On the punctured torus the number of essential self-intersections of a homotopy class of closed curves is bounded (sharply) by a quadratic function of its combinatorial length (the number of letters required for its minimal description in terms of the two generators of the fundamental group and their inverses). We show that if a homotopy class has combinatorial length L, then its number of esse...

The filter generator consists of a linear feedback shift register (LFSR) and a Boolean filtering function that combines bits from the shift register to create a key stream. The nonlinear combiner generator employs several (LFSRs) and a Boolean function that combines bit from all the registers to generate the key stream. A new attack on the filter generator has recently been described by Rønjom ...

The inversive congruential method is a uniform pseudorandom number generator which was introduced recently. For a prime modulus p the discrepancy D of k-tuples of successive pseudorandom numbers generated by this method determines the statistical independence properties of these pseudorandom numbers. It was shown earlier by the author that Dik) = 0(p~l,2(\oëp)k) for2<k<p. Here it is proved that...

We prove a new representation of the generator of a subordinate semigroup as limit of bounded operators. Our construction yields, in particular, a characterization of the domain of the generator. The generator of a subordinate semigroup can be viewed as a function of the generator of the original semigroup. For a large class these functions we show that operations at the level of functions has ...

Hydropower plant and especially micro-hydropower plant is an available, reliable and economical energy source. Micro-hydropower plant is one of the most environment-friendly technology, use and development of which leads to reduction of energy consumption sporadically and worldwide. Along with the growth of these power plants, the issues related to the control of electrical parameters such ...
